 In recent years, OA equipment has been widely used in office spaces along with its variety, and various and large-scale wiring processes on floors have become a problem. . For this reason, the necessity of floor wiring management is increasing. In response to this, the use of double-floor panels is expected and is being widely used.

Recently, double-floor panels have been diversified, such as wiring groove type, support leg integrated type and separated type, and it is easy to respond to linears. Because it is possible, it is a floor-standing, lightweight, easily constructed by anyone, and can be used on uneven floors, with less rattling. The demand for files is increasing.

 In particular, wiring-groove panels have been widely used. As this type of panel, for example, a floor panel described in JP-A-62-284854 is known. This is composed of a wiring groove forming block consisting of a molded resin sheet and concrete, and has a load-bearing capacity and weight, so there is no displacement, etc. There is an advantage that the blocks can be laid with the blocks struck against each other. However, due to the flexibility of the molded resin sheet, it has the characteristic of being able to follow the ground. However, this is a composite material, it is heavily laid, requires a lot of wiring cover to cover the wiring groove, and therefore has a large number of parts, so it must be laid. There was also a problem that it took time to complete the construction and also to carry in and out the construction.

 On the other hand, there is a panel with integrated support legs. This type of panel is a type that is different from the separated type, in which a plurality of support legs are connected at a connection part and integrated to form a unit panel. A panel is laid on the support legs. This is known, for example, from Japanese Utility Model Application Laid-Open No. 60-164537, Japanese Patent Application Laid-Open No. 4-124366, Japanese Patent Application Laid-Open No. 5-28834, and the like.

These are unit-laying unit panels consisting of a plurality of support legs, and are therefore unitary in the laying work. The lack of a connection structure between the panels causes misalignment, and the panels are made of steel plate to ensure strength and are made thicker. However, there was a problem that the construction was troublesome and the workability was deteriorated. However, this kind of non-stick is often large, and even if the support leg has the ability to follow and absorb irregularities, the panel is large. Therefore, it had the disadvantage that it did not become uneven, and there was a problem that rattling occurred when walking.

 In order to solve such a problem, a structure such as a structure in which the fitting between the support and the panel is forcibly and tightly fitted with a fastening member such as a fastener so as to be firmly connected. However, various fixing means have been envisaged. However, in each case, there was a problem that the number of parts increased, the reliability of the fixed force was lacking, and the workability was worsened.

 On the other hand, the connection structure of the panel is, for example, typically the one described in Japanese Utility Model Laid-Open No. 6-85845. Of these, the type that is engaged and connected is to use a completely different engaging structure from that of the panel legs, and further to the legs. Due to the configuration of connecting with a small interval between them, the structure is complicated, it is difficult to attach and detach it, the workability of connecting laying is poor, and the distance between the legs is very small. Due to the proximity of the steel structure, there is a problem of poor track following.

In addition, for example, a coupling structure composed of a ring body and a support portion fitted to the ring body described in Japanese Patent Application Laid-Open No. Hei 6-322 947 etc. In other words, the workability of the connection work must be such that the ring body is fitted so that it is passed over from the height of the support part and fitted. There is a problem that the installation work is troublesome.

 As described above, in the prior art, any of the types of double-floor structures and construction methods described above are of the floor-standing type and have a relatively simple configuration. However, there is a floor panel that has a support part that satisfies both requirements, as it can follow uneven floors, has little rattling, and is easy to construct. Absent.

BEST MODE FOR CARRYING OUT THE INVENTION

 Next, an embodiment of a floor panel having a support portion according to the present invention will be described in detail with reference to the accompanying drawings.

 One aspect of the various aspects of the present invention relates to a structure in which a plurality of floor panels are connected and connected by an upward-downward insertion type concave-convex fitting. The other one has a main configuration of a support part group, a connecting part, a coupling support part, and a coupling fitting part, and the other one has a support part. The present invention relates to a fitting structure formed by engagement of a panel with a panel. Still another aspect relates to a panel laying and support cutting structure and a construction method thereof.

Explanation of floor panel and panel basics and overall configuration

 Referring to FIG. 1A and FIG. 1B, the floor panel according to the present invention is basically composed of a support group composed of a main leg 14 and an auxiliary leg 16. The connecting parts 18 and 22 which connect the supporting parts to each other, extend substantially radially at a predetermined width, and are arranged at substantially equal intervals to each other, and the connecting parts 18 and A first connecting portion 24 and a second connecting portion 26 extending outward from the support portion on one side of at least one of the support portion groups and at least one of the other support portions. It is intended to include

In addition, screw 30 onto the top of each support 14 and 16 A double floor is constructed by laying multiple units so that they are supported at the corners and corners. More specifically, the floor panel 10 has a thickness of about 400 ram to about 400 ram, based on the size of the tile as a floor finishing material. It is set to have a size of 600 ram square, and the connecting portions 18 and 22 are continuously formed in a substantially X-shaped or cross-shaped shape, and the X-shaped intersections are formed. The main leg 14 and the auxiliary leg 16 are arranged at regular intervals at predetermined intervals so that the support strength of the floor panel upper surface is maintained. Can be stabilized.

 Further, the first and second joints 24 and 26 have the same configuration as the auxiliary leg 16 and have a substantially concave bottom surface. The height is lower than this, for example, it can be inserted or engaged in an upward and downward plug-in manner, for example, a substantially convex that is engaged or fitted in the substantially concave shape. And a second connecting portion 26 formed in a shape. As a result, the plurality of floor panels 10 can be connected or positioned with each other by engaging or mating the first and second joints 24 and 26. It can be fixed easily and securely, and the joints 24 and 26 of the floor panels are inconspicuous in appearance, and a large number of floor panels 10 are evenly continuous on the floor. The floor panel can be laid in a targeted manner, and floor panel laying workability is improved. Further, since the support portions 14, 16, and 24 are uniformly arranged at predetermined equal intervals from each other by the connection portions 18 and 22, the floor surface It can be made to sufficiently follow the non-land of the country.

The floor panel 10 is designed to be integrally molded. Since it is easy to manufacture, it is suitable. For example, flame-retardant and non-flammable resin molding is most common. These connecting parts 18 and 22 and the first and second connecting parts 24 and 26 are integrally formed of the floor panel 10 with a minimum amount of resin. In addition, in order to make parts common to the panel 30, a thin steel plate of the same shape is used, and reinforcement is achieved by punching and bending only. Therefore, it is lightweight, easy to transport and lay, and low cost.

 The support group is composed of main legs 14 and auxiliary legs 16 having different diameters, and the main legs 14 cover the four corners of the panel 30 by 1/4 each. Panel 30 is supported at four locations, so that it is supported by areas of equal area. The supporting legs 16 are supported almost entirely near the center of the panel 30, but the supporting legs 16 support the four panels 30, whereas the auxiliary legs 16 support the four panels 30. The 16 functions as a support to support a certain load.

The structure of the main leg portion 14 and the auxiliary leg portion 16 is formed into a columnar shape having an arbitrary planar shape such as a polygonal shape or a circular shape, and a panel is provided on the upper surface 14a. Engaging portions (or engaging portions) 14b and 14c are formed so that the socket 30 can be installed by engaging and fitting. The corresponding panel 30 also has mating portions (or mating portions) 32, 38 and 34 (Fig. 6B) at its four corners 36 (Fig. 6A). It has been. On the other hand, the nozzle 30 is, for example, 1/6 to 1 area of the area of the tire power pad or floor panel 10 (about 40 Oram to about 60 Oram square in this embodiment). An area equal to about / 3 is preferred. In the illustrated embodiment, the floor panel 10 has a substantially square shape and is about lOOraii! So that the floor panel 10 is divided into a plurality of sections. It is a thin sheet made of steel plate with a thickness t of about 1.0 mm to 2.5 mra (typically 2.3 ram), set to a size of ~ 200 mra square (typically 165 mm).

 As a result, a plurality of the panels 30 are laid so as to be supported by the upper surface and the corners of each of the support portions 14 and 16, whereby the panel 30 is laid. The construction of the rule 30 becomes easy, and the support strength can be stabilized by forming a uniform support surface with a simple structure. However, by setting the size of the panel 30 as described above, it is possible to imitate the non-landing following of a large number of laid floor panels 10.

 This panel 30 has the same shape and the same support structure as the mating structure. Even though it is a thin plate, it is enough by punching and bending. Since high strength can be obtained, the number of parts can be reduced, and low cost can be achieved.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. These embodiments are examples in which the present invention is applied to the construction of a double-floor structure, and the present invention is based only on these. They are not to be construed as limiting.

 FIGS. 1A, 1B, 2A, 2B and FIGS. 3A-3D show an embodiment of a floor panel 10 for a double floor, which includes legs. This is an example in which the shape of the part and the configuration of the connecting part for connecting the legs are different. As shown in FIGS. 1A and 2B, the floor panel 10 has two types of legs, the main leg 14 and the area of the support surface more than the main leg 14. It has narrow auxiliary legs 16 and. The main leg portion 14 and the auxiliary leg portion 16 are connected to each other by a band-shaped connecting member 18 having a predetermined width. As a result, it is possible to reduce the weight of the floor panel.

 The main landing gear 14 shown in FIGS. 1A, 1B, 2A, and 2B has a substantially octagonal flat surface shape. The legs 14 may have, for example, a circular planar shape as shown in FIG. The connecting members 18 for connecting the legs are provided with a larger number of connecting members 18 than the floor panels in these embodiments to improve the connection strength. You can do it.

 In the illustrated embodiment, nine main legs 14 and four auxiliary legs 16 are provided, and the auxiliary member 16 is placed on these legs between the main legs 14. The panel 30 as a floor plate to be installed can be supported.

2A and 2B, a cross-shaped groove 14b is formed on a support surface 14a, which is the upper end surface of the main leg portion 14. The groove 14b is used to lock the panel member in the groove when the panel 30 is installed.

 In this way, a leg group is formed in a state where the main leg 14 and the auxiliary leg 16 are connected by the connecting member 18, and a further connecting arm is formed on the leg group. A part 22 is provided. The connecting arm portion 22 is formed by projecting a connecting arm 22 having the same configuration as the connecting member 18 from the outermost main leg portion 14 to form a connecting arm 22. A connecting leg 24 or a connecting small protrusion 26 is formed at the tip of the arm 22 so that the plane shape is substantially V-shaped.

 This is a shape for improving the strength of the protruding connecting arm portion 22 and is effective for withstanding stress generated during construction or the like. . Also, the tips of these connecting arms 22 are placed on the substantially square sides (shown by broken lines 100 in the figure) surrounding the leg group. It is set to be positioned. In the illustrated embodiment, the connecting leg portion 24 and the connecting small protrusion 26 are separately arranged and formed on each two adjacent sides of the rectangular shape.

Also, as can be understood from FIGS. 1B and 2B (a diagram showing the configuration as viewed from the configuration of FIG. 1A), the main legs 14 have the same height. The auxiliary leg 16 is formed to have a height that is slightly lower than, for example, the height of the main leg 14. More specifically, the auxiliary leg portion 16, which is positioned substantially in the center of the panel 30 described later, which is bridged and supported between the main leg portions 14, When the load is applied to the central position of the upper floor member, the connecting legs are configured to support this in a supplementary manner, for example. The part 24 has substantially the same shape and height as the auxiliary leg 16, and the distance from the main leg 14 is set substantially the same as shown in the figure. . The connecting small projection 26 is set to a height that is extremely lower than the heights of the main leg portion 14 and the auxiliary leg portion 16. In the present embodiment, the height is set to, for example, approximately one third or less. The upper end is formed into a rounded R-shaped surface.

 FIG. 2A is a schematic plan view of a state in which a plurality of floor panels 10 (10-1 10-2) according to the embodiment of FIG. 1A are connected. As shown in the figure, the two floor knurls 10-1 and 10-2 are engaged with the two connecting small projections 26 by inserting the connecting legs 24 in a plug-in manner. As a result, they are connected. As described above, since the connecting portions that can be connected and engaged are formed using the two sides of the above-described substantially square shape, a large number of support leg units. Nore 10 (10— 1 10-2 10-3

 When 10-n) are installed continuously with a two-dimensional spread, it is possible to perform them sequentially and easily without having to consider complicated arrangements.

Also, as shown. The cell 30 is set up so as to be supported by the four main legs 14. The panel 30 is made of, for example, metal, and has four corners with improved load bearing strength. Therefore, it has a bent portion 34 bent downward, and the bent portion 34 is installed by being engaged with the groove 14 b of the support surface of the main leg portion 14.

 As shown in FIG. 2A, in a state where two floor panels 10, that is, 10 _ 1 and 10-2 are connected, the connecting portion of the two is connected to the main leg 14. The positional relationship between the main leg portion 14 and the auxiliary leg portion 16 where the leg portion 24 is not a connecting portion, and the support relationship between the panel 30 and the main leg portion 14 can be maintained. Therefore, the connecting structural members are not exposed and conspicuous, and the wiring space of the double-floor structure is not changed irregularly. It is understood that the parts 14 and 16 are formed on the floor at regular intervals.

 The connection operation of the floor panels 10 is basically performed as follows. That is, as shown in Figure 2B, first install the other floor panel 10-1 on the underlying floor. After that, the operation of installing the next floor panel 10-2 is not performed. At this time, the floor panel 10-2 is connected to the two connecting small projections 26 of the floor panel 10-1. -Set the corresponding connecting feet 24 of 2 so that they cover from the bottom side.

 For example, the floor panel 10 is configured such that the main leg 14, the auxiliary leg 16, and the connecting leg 24 are arranged in reverse, and the main leg 14 and the main leg 14 are connected to each other. The floor panels 10 may be connected to each other by the connecting small projections 26.

Next, the connecting arm 22, connecting legs 24 and connecting An example of a connection structure composed of the small projections 26 for 1 f will be described. FIGS. 3A to 3D are schematic enlarged views of the connecting portions of the respective floor panels. As shown in FIG. 3A, at least the connecting member 18 of the floor panel 10 is made of, for example, an integrally molded resin and is made thin to have flexibility. It is formed so that the connecting arm portion 22 can be easily bent upward. With the applied force, as shown in Fig. 2B, while the adjacent floor panels 10-2 were once placed on the floor, they were displaced, The connecting leg 24 can be put on the connecting small protrusion 26 of the floor panel 10-1. In other words, it is sufficient to perform the covering operation at a position lower than the height of the leg (the height of the small connecting projection). Therefore, there is no need to perform the operation of lifting and connecting the entire floor panel 10 as in the conventional technology, and the connecting operation is an easy operation.

In the above-described embodiment, the configuration of the leg portion is an example in which the main leg portion 14 has a large supporting area and the auxiliary leg portion 16 has a small supporting area. The present invention is not limited to such a leg configuration, and the leg group may include only the main leg 32 having a common support surface. FIG. 3B shows an example of the configuration of a connecting portion in an embodiment in which such a main leg portion 32 alone forms a leg group o

 In this case, the connecting small projection 36 is set to a height that is less than half the height of the main leg 32, and the connecting leg 34 has the same height as the main leg 32. It has an outer shape, and a rib 35 as shown in the figure is provided inside, for example, to enhance its strength. In the same manner as the structure shown in FIG. 3A, the connecting operation is performed by engaging and installing the small connecting protrusions 36 so as to cover the connecting legs 34.

FIG. 3C and FIG. 3D show another example of the configuration of the connecting leg and the connecting J-projection of the connecting portion. First, the example shown in FIG. 3C is a modification of the configuration of the connecting small projection, and the configuration of the connecting leg 24 is the same as that of the example shown in FIG. 3A. The same is true. More specifically, the connecting small projection 40 is divided into two parts at almost the center, and the two separated parts slightly separated from each other are open-ended connecting legs 24 having an open bottom. Are pressed from each other by the upper force, and the engaging operation is performed. As a result, the two separated portions of the connecting small protrusion 40 are connected in a direction to spread outward. Since the leg 24 is urged, the connection and engagement between the two is further strengthened.

 FIG. 3D shows an example of the configuration of still another connection part. In this embodiment, the connecting small projection 42 is composed of two pieces 42a and 42b, and the two pieces 42a and 42b exert a force of a predetermined magnitude. By adding, it is configured to be able to bend in a direction closer to each other. Of course, it may be composed of two or more pieces. On the outer surface of each piece, a projecting portion 43 whose diameter is increased outward is formed.

 On the other hand, holes 25 are formed in the side walls of the connecting leg 24 as engagement portions with which the above-mentioned projections 43 engage, respectively, at positions facing the projections 43. It is. Accordingly, the two legs 42a and 42b of the small connecting protrusion 42 are formed by covering the connecting leg 24 from above the small connecting protrusion 42. They are turned in a direction approaching each other. At the end of the covering operation, the small projection 42 for connection is fitted with the projection 43 engaged with the hole 25. In this way, in this embodiment, the connection is stronger than the engagement state in which the connection leg is merely placed on the small connection protrusion as shown in FIGS. 3A and 3B. The state is secured.

The connecting small projections 40 and 42 described above are the ones illustrated in FIGS. 3C and 3D, but the present invention is not limited thereto. In short, embossing and punching Any structure that can be attached and detached upward and downward, can be engaged at the time of attachment, and can be used as a guide for positioning o

 FIG. 5 shows an example in which a floor panel 10 according to one embodiment is installed on the floor of a building to form a double-floor structure. In this figure, the end of the installation area is shown. The installation of the rim, for example, near the wall of the floor, is shown. As shown in Fig. 5, a plurality of floor panels 10 according to the present invention are connected in order and installed to a predetermined position near a wall. Here, a border panel 50 is installed near the wall, from which the width can be adjusted by cutting. The border cover 52 is installed on the border panel 50 closest to the wall, and the other area of the border panel 50 is located in the other area. Border sheet 54 is installed.

On the other hand, the end of the floor panel 10 is set so that the connecting leg 24 is located. The position of the border panel 50 is adjusted so that it reaches from the connecting leg 24 to a predetermined position. As a result, the panel 30 is bridged between the border panel 50 and the main leg 14 so that the panel 30 can be mounted on the border panel. It is reliably supported by the cell 50 and a part of the outermost main leg 14 and the connecting leg 24 located between them. The supporting structure that the connecting legs 24 support the panel 30 at almost the center position is the same as the structure other than the peripheral part of the floor panel. Therefore, floor pa The stability of the installation state of the panel 30 at the end of the installation of the cell 10 is similarly ensured.

 As described above, even if the panel 30 is installed in the area where the border panel 50 and the floor panel 10 are connected to each other, the panel 30 is located at the four corners. Are supported by the border panel 50 and the main leg 14, and the auxiliary leg 16 or the connecting leg 24 can be supported in the approximate center position. It is located in the state. More specifically, this supportable state means that the height of the auxiliary leg 16 and the connecting leg 24 is slightly lower than the height of the main leg 14. For example, when a load due to the installation of the device is applied to the center position of the panel 30 or a load due to human walking is applied, the load is changed according to the load. It supports the center of the radiused panel 30.

 This makes it possible to reduce the thickness of the steel plate of panel 30 as much as possible while maintaining the function of maintaining the load resistance. It is also possible to achieve that weight reduction and cost down. For example, the thickness can be made thinner than 2.3 t, for example, 1.6 t, and a significant cost reduction can be achieved.

On the other hand, in the case of wall-side treatment, as shown in FIG. 5, the connecting small protrusion 26 is located on the border panel 50 side instead of the connecting leg 24. There is. in this case , ,. The bridge 30 can be bridged between the support section 14 and the border panel 50, so that the remaining space beside the wall can be filled. As shown in the figure, since the connecting small projections 26 are lower in height as shown in the figure, they cannot support substantially the center of the rear surface of the panel 30, resulting in insufficient strength.

 In order to prevent such a state, the third supporting portion 45 of the same member is connected to the connecting member 24 so as to have the same height as the connecting leg portion 24 and the supporting portion 14. It may be formed so as to be inserted into the small projection 26 and be in the same state as the connecting leg 24. As a result, as in the case of connecting the floor panels, the bog can be easily constructed by the vertical insertion work.

 The present invention is not limited to the configuration of each of the above-described embodiments, and various modifications are possible within the scope of the invention. For example, the number and shape of the supporting legs constituting the leg group are not limited to the above-described and illustrated configurations, and various numbers and shapes may be set. Good.

 In addition, the internal structure of each leg can be a solid structure, and all the legs are formed as hollow structures. It is also possible to reduce the weight by installing a rib at the end to reinforce the strength.

As described above, according to these embodiments, when laying a floor panel, it is possible to achieve a floor panel that can be easily connected with a simple configuration. I can do it. In addition, stabilization of the connection state can be ensured, and attachment and detachment is easy, and even if it is once installed on the floor surface, its simple operation can be achieved. Can be attached and detached. Also, the panel Since the connecting member does not protrude between the legs supporting the arm, the connecting portion is not conspicuous. When used as a double floor, wiring space can be effectively secured between the legs.

 FIGS. 6A and 6B are useful for explaining the panels shown in FIGS. 1A and 2B described above, and FIG. 6A is a front view of the panels. Figure 6B shows the side view. The panel 30 is made of a steel plate having a predetermined thickness and is formed in a flat plate shape. As shown in FIG. 6A, the panel 30 is formed in a substantially square shape, and each corner of the lower surface thereof is formed. Projections 32 projecting downward are provided at the area positions of the parts 36, respectively. As shown in FIG. 6B, the protruding portion 32 is formed such that its protruding outer surface 32 has a substantially hemispherical shape.

Further, as shown in FIGS. 6A and 6B, when the panel 30 is made of a steel plate, the panel 30 faces downward at a predetermined position on each side so as to secure its rigidity. Thus, the side walls 34, which are bent portions formed to have a predetermined height h, are provided on each side. The side wall part 34 is no. It is installed at a position separated by a predetermined distance so that it can be easily attached to and detached from the four corners 36 of the cell 30, and both ends of the main leg 14 described above are attached to both ends. It has an insertion wall portion 38 that is inserted into the cutout groove portion 14b. The height of the insertion wall portion 38 may be a height at which the notch groove portion 14b can easily be attached and detached, and may be slightly shorter than the side wall portion 34. Almost half of the side wall part 34 A range up to height is preferred.

 In order to facilitate attachment and detachment of the main leg 14 to and from the groove 14b, the engagement force is appropriately adjusted because the side wall 34 is notched in a predetermined amount in a stepped manner. The insertion wall portion 38 thus formed. The present invention is not limited to this specific structure. The engaging force can be adjusted by changing the height and the area or the area of the insertion wall part 38, and it is optional.

Ό o

 Next, regarding the fitting structure of the main leg portion 14 and the panel 30, the configuration of the shock absorbing sheet 40, and the buffer sheet 40, the floor panel 10, the main leg portion 14 and the main leg portion 14 will be described. The positional relationship of each of the panels 30 and 30 will be described below with reference to FIG. FIG. 7 is an exploded perspective view showing a state in which one panel 30 is placed on the floor panel 10, and is an enlarged exploded view in which main parts are disassembled. As shown, the buffer sheet 40 includes a panel 30 and a floor. It is a cushioning member interposed between the main leg portion 14 of the cell 10 and the main leg portion 14. It is advantageously made of cushioning-like elastic material, for example, flexible synthetic resin, foam, rubber, non-woven fabric, etc. Flat material, for example, 0.5 mn! A sheet formed with a thickness of about 2.5 flim is used.

In the illustrated embodiment, the cushioning sheet 40 is formed in an approximately octagonal shape in accordance with the shape of the supporting surface 14a of the main leg portion 14, and the cushioning sheet 40 is formed on the supporting surface 14a. A notch 41 is provided at the position corresponding to the notch groove 14b when placed. ing . The buffer sheet 40 is placed on the support surface 14a of the main leg portion 14 in an overlapping manner so as to cover the through hole 14c, and is bonded on both sides with a double-sided adhesive tape or the like (not shown). It is fixed to the support surface 14a by a member.

 As described above, the panel 30 is placed on the upper surfaces of the four main legs 14 and the one auxiliary leg 16 via the loose mouth sheet 30 therebetween. . At this time, the corner 36 of the panel 30 is placed on a portion that occupies approximately one-fourth of the support surface 14a of the main leg 14, and the corner of each panel 30 is They are laid at predetermined small intervals so that they do not come into contact with each other.

 The projection 32 of the panel 30 is inserted from the upper surface of the buffer sheet 40 into the through hole 14c of the support surface 14a. As a result, the panel 30 is placed without causing rattling due to the engagement state on the floor panel 10. At that time, the insertion wall 38 of the panel 30 is inserted into the notch groove 14 b through the cutout 41, and the panel 30 is placed on the floor panel 10. It can be securely locked.

 Here, in the area of the corner 36 of the panel 30, a flat plate portion that does not form a wall from the corner to a predetermined length is formed, and the main leg 14 is formed. It is placed on the support surface 14a of the battery in a superimposed manner via the buffer sheet 40. By providing such a flat portion of the corner portion 36, the amount of biting into the cut groove portion 14b of the insertion wall portion 38 can be suppressed. .

As a result, after the panel 30 is placed on the floor panel 10 The panel can be easily removed again, for example, by lifting the panel 30 using a predetermined panel mounting / dismounting jig and lifting the floor panel. It can be removed from the socket 10.

 Next, the engagement between the main leg 14 of the floor panel 10 and the panel 30 will be described in detail with reference to FIGS. 8A, 8B and 8C. explain . 8A, 8B, and 8C are cross-sectional views taken along line VIII-VIII when the panel is installed in FIG. First, the main landing gear 14 and the panel 30 with the buffer sheet 40 interposed in a flat condition where the foundation floor of the building has no unevenness on the floor. The case of the relationship with is described with reference to FIG. 8A.

 As shown in FIG. 8A, the projection 32 of the panel 30 is inserted into the main leg 14 from above the through hole 14c. At this time, since the taper portion 15 as a locking portion is formed on the support surface 14a side of the inner side surface of the through hole 14c, the through hole 14c of the projection 32 is formed. It can be easily inserted into the building.

Further, since the lower part of the through hole 14c is open, the projection 32 inserted into the inside of the through hole 14c does not protrude from the bottom, so that the protrusion of the through hole Mc does not protrude. It is supported only by paper part 15. Accordingly, the projection 32 is securely fixed to the through-hole 14c, for example, when the panel 30 bends temporally due to a load or the like. Also, the projection 32 can be securely supported on the through hole 14c. Further, since the projection 32 is held so as to be wrapped by the buffer sheet 40, it depends on the elastic force of the buffer sheet 40 itself. As a result, a good buffering action in the vertical direction is provided. Further, since the buffer sheet 40 is sandwiched between the outer surface 32a of the projection 32 and the taper portion 15, it is possible to prevent damage such as cutting of the buffer sheet 40. Can be protected.

 Here, as shown in FIG. 8A, the insertion wall portion 38 of the panel 30 is inserted into the cutout groove portion 14b through the cutout portion 41 of the buffer sheet 40. In addition, the notch portion 41 is bent downward, and the tip portion 41 a thereof is always in contact with the insertion wall portion 38. Therefore, for example, the walking sound generated from the panel 30 due to walking on the panel 30 causes discomfort, particularly to human hearing. This makes it possible to suppress high-frequency sounds that can be easily detected.

Next, with reference to FIGS. 8B and 8C, the engagement relationship between the main landing gear 14 and the panel 30 when there is unevenness on the foundation floor surface. It is explained. As shown in FIG. 8B, when the floor panel 10 follows the unevenness of the foundation floor and the position of the main leg 14 is deviated, the projection 32 of the panel 30 and the main leg are displaced. The fourteen through-holes 14c are not engaged with each other, and are arranged at positions shifted from each other. If the amount of displacement is small, the outer surface 32a of the projection 32 will bite into the buffer sheet 40 existing between the tapered portion 15 and the projection 32. Securely lock 32 to main leg 14 This is powerful, and at the same time, the cushioning of the panel 30 to the floor panel 10 can be obtained.

 As indicated by the symbol F in the same figure, the force of the buffer sheet 40 between the panel 30 and the support surface 14a, as well as the force of the two, are shown. Direct contact can be prevented, and the cushioning of the panel 30 can be maintained.

 Figure 8C shows the panel installation state when the panel 30 floats slightly above the support surface 14a of the main landing gear 14 due to unevenness of the foundation floor. Is shown. In this case, as shown in the figure, the portion 32a submerged in the through hole 14c of the buffer sheet 40 has a panel due to its elasticity, that is, the cushioning property. It comes into contact with the projection 32 of 30 and holds it. Therefore, the result of the unevenness of the foundation floor surface. It is possible to prevent rattling of the cell 30. Then, as shown in the figure, when the distal end portion 41a of the cutout portion 41 of the buffer sheet 40 comes into contact with the insertion wall portion 38 and the side wall portion 34 of the panel 30, walking is performed. The pedestrian noise generated by time is synergistically reduced.

Also, for example, when the floor panel 10 is on the support surface 14a without being locked by the through hole 14c due to the large unevenness of the foundation floor, the notch is notched. By inserting the insertion wall portion 38 into the groove 14b, the panel 30 can be securely locked, and a cushion is provided between the panel 30 and the wall portion 38. Since the sheet 40 is interposed, cushioning can be maintained. .

 From the above, according to the double-floor panel structure of the present embodiment, even if the floor panel 10 absorbs and follows the unevenness of the foundation floor surface, it will not be possible. The panel 30 placed on the upper surface of the floor panel 10 can be reliably positioned and fixed on the floor panel 10. Panel 30 is the floor. It can be installed in a state where it is securely locked without rattling on the nap, and when walking on the panel 30, etc. The generated reverberation can also be reliably suppressed.

 Further, the structure of the projections 32 of the panel 30 is not limited to those of the illustrated embodiment, and various changes can be made within the gist of the present invention. In the case of a steel plate, nail-like or tongue-like projections may be formed by punching and pressing. In short, it is only necessary that the positioning and fixing of the panel and the non-woven fabric due to the buffer sheet 40 be capable of engaging with the through hole Uc.

As shown in FIGS. 9A and 9B, which are schematic diagrams, the protrusion 32 in the above-described embodiment and a through hole into which a part of the protrusion 32 is inserted. Even for the type without 14c (Fig. 9A), the tip 41a of the notch 41 should always be in contact with the insertion wall 38 (Fig. 9A). According to FIG. 9B), the effect of reducing the effect of the walking sound generated from the panel 30 can be obtained. In this case, as shown in FIG. 9B, the support surface 14a of the main leg 14 and the panel 30 are separated from the cushion sheet 40. Since the contacts are overlapped with each other, it is possible to suppress the rattling of the panels 30 provided at a predetermined interval from each other.

 More specifically, as shown in FIG. 9A, at least the tip of the cushioning material 20 is brought into contact with the side surface of the panel 30 laid on the support portion 10. Or, it is configured so as to be held or pinched, and the above-mentioned cushioning member 20 for reducing the walking sound is provided in the groove 16 formed on the upper surface of the support portion 10. Then, when the panel 30 is laid as shown in FIG. 9B, the panel ends 38 at the four corners are fitted into the grooves 14b of the support portion 14, and The tip 41a of the cushioning member 40 (the notch 41 in FIG. 7) contacts at least the side surface of the panel end portion 38, or holds both side surfaces of the end portion. In this state, the panel 30 is held on the support.

 As shown in FIG. 9B, the holding of the panel 30 is performed because the tip 41a of the cushioning member 40 extends across the inner sides of both sides of the panel end 38 as shown in FIG. 9B. As a result, it is possible to suppress the sound of the walking sound during walking, and particularly to suppress high frequency components that are easily perceived by human ears.

 Conventionally, the cushioning material 40 comes into contact with the side edge of the panel and is held by merely fitting the floor panel 10 into the groove on the upper surface of the support portion, so that the walking sound can be buffered. In this case, it is only necessary to fit the cushioning member 40 into the groove 14b on the upper surface of the column, so that the construction is easy.

* When a load is applied on the panel or at the top of the panel, By fitting at least one end of the loop end into the groove 14b, at least one of the groove and the cushioning member 40 is fitted to the end of the panel 30. The contact makes it possible to hold the panel 30 on the support part, and this ensures that the panel 30 is released even if there is unevenness on the floor surface. Sound generation can be reduced.

 Engagement or engagement structure between the main leg portion 14 and the panel 30 shown in FIGS. 7, 8A, 8B, 8C, 9A and 9B described above. In contrast to the embodiment shown in FIG. 10, another modified embodiment will be described with reference to FIG. A projection 51 is provided on the support portion 54 of the floor panel 50 laid on the foundation floor surface, while a through hole 65 is provided on the panel 60 placed on the floor panel 50. An example in which is set is shown. This embodiment corresponds to a case where the through-hole 14c shown in FIG. 8A of the above-described embodiment is installed upside down, and has the same functions and effects in this embodiment. Can be obtained.

 As shown in the drawing, the support portion 54 has a different size depending on its disposition position, and has a predetermined number of protrusions 51 protruding at a predetermined position inside the support portion 54. ing . As shown in FIGS. 8A, 8B, and 8C, the shape of the projection 51 is such that the projection 32 in the embodiment shown in FIG. 3A is turned upside down. Corresponding to the shape.

The panel 60 includes a plate portion 61 formed in a flat plate shape, and four legs 62 formed below each of the corner regions. Each leg 62 includes a wall 63 having a predetermined height, Bottom portions 64 extending in the direction approaching each other by a predetermined width in parallel with the plate portion 61 from the lower end portion of the wall portion 63 are provided. . Each bottom surface portion 64 has two through-holes 65 on its lower surface, which can be engaged with the projections 51 provided on the support portion 54, at predetermined positions. . This through hole 65 penetrates the bottom surface portion 64.

 The buffer sheet 80 is formed in a substantially rectangular sheet shape that can be positioned and positioned on the bottom 53 in the support portion 54. The cushioning sheet 80 can be simply attached to the bottom portion 53 of the support portion 54, and does not need to be attached as in the above-described embodiment. It is not necessary to provide a cut-out part 41 through which the insertion wall part 38 of the panel 30 passes.

 In the embodiment described above, the projections 32 of the panels 30 and 60 or the projections 51 of the support portion 54 cause the panels 30 and 60 to have Positioning and fixing during installation can be performed easily and accurately, and double-floor construction can be performed easily.

It should be noted that the floor panel structure of the present embodiment is not limited to the configuration of each of the above-described embodiments, but may be variously modified within the scope of the present invention. It is. For example, the above-described through hole 14 c is set as a penetrated hole, but it is not limited to this form, and the recessed projection 3 2 Alternatively, it may be formed as a concave hole shape having a bottom at a position where the buffer sheet 40 pushed in by the above does not contact. Further, it is preferable that the floor panels 10 and 50 are mainly formed of a flame-retardant or non-flammable resin, and the size per one sheet is preferably not larger. The size is set to about 450-600mni square based on the carpet size.

 Each of the panels 30 and 60 has a substantially square shape obtained by dividing the floor panel 10 into a plurality of sections and is, for example, about 100 to 200 mm square, and has a thickness of about 1.0. It is preferable to use a thin steel plate formed with 2.5 ram. This makes it possible to follow the unevenness of the foundation floor and absorb it, and it is lightweight, and therefore easy to transport and lay, and at the same time, has a high load-bearing capacity. A satisfactory double floor panel structure is provided.

 Further, the materials of the buffer sheets 40 and 80 are not limited to those of the above-described embodiments, but include, for example, damping materials and sound absorbing materials. It is possible to use timber to absorb the rattling of the panel 30 due to unevenness of the foundation floor, and reduce the reverberation generated from the panel 30 when walking. It only needs to be made of a cushioning elastic material that can do this o

As described above, according to the floor panels 10 and 50 according to the present embodiment, the panels 30 and 60 can be reliably supported and fixed. Position shift can be prevented. Also, it is possible to prevent rattling of the panels 30 and 60 without being affected by unevenness of the foundation floor, etc. Suppresses reverberation from cells 30 and 60 can do .

 Next, the detailed structure of the support leg portion 14, the notch for cutting, and the method of construction will be described. FIG. 11A is an enlarged perspective view of the first support portion 14 as a main leg portion, and FIG. 11B is a bottom view of the first support portion 14. The first support portion 14 as a main leg portion has a groove portion 14b formed as a slit and serving as a guide for a separation position of the support portion 14. A notch 14d is formed in at least one of at least one of the lower portion and the upper portion of the outer side of the support portion 14 by being connected to the groove portion 14b. A cutting tool such as a cutter is applied to the cutout 14d so that the support 14 can be separated by the action of an upward and downward force. The support portion 14 is configured with four hollow blocks 14-1, 14-2, 14-3, and 14-4 at four corners, and each block is provided with four hollow blocks 14-1, 14-2, 14-3, and 14-4. The upper surface 14 a, the outer side surface 15, and the inner inner wall 13 are formed in a cylindrical shape having a predetermined thickness t, so that two or four support portions 14 are provided. Even when they are separated from each other, they each have strong strength.

 In the illustrated embodiment, the cut portion 14d is provided at a position between the lower connecting portion 17 outside the support portion 14 and the upper surface side 14a. It may be located only in the outer, inner, or inner positions, and is not limited to these particular forms, but may be used separately, Or multiple combinations are possible.

On the other hand, FIGS. 12A and 12B are the same as those shown in FIGS. 11A and 11B described above. Blocks 14-1, 14-2, 14-3, and 14-4 are schematically indicated by diagonal hatching. In each of FIGS. 12A and 12B, the upper diagram is a plan view and the lower diagram is a side view. The first support portion 14 can be separated by cutting the support portion 14 from the above-described groove portion 14b in which the side wall portion 34 or the insertion wall portion 38 of the panel 30 fits. A notch 14d is provided. The cutouts 14d are formed on the outside of the support 14 in FIG. 12A and on the inside of the support 14 in FIG. 12B based on the position of the groove 14. Each is set up.

 In this way, at least one of at least one of the lower outer side (joining part 17), the inner side, and the upper side 14a of the support part 14 is provided. By providing the cutouts 14d, for example, the action of a force for cutting a cutting tool such as a cutter or a nut into the cutouts 14d in an upward and downward direction. Therefore, it is possible to easily cut off only, for example, it is possible to easily form a storage space for wiring equipment and the like.

 The round hole 19 in the center of the upper surface 14a of the support portion shown in the figure has an area of 1/4 that of the upper surface of the support portion 14 when forming a storage space for wiring equipment and the like. It is formed to prevent the cut by the cut from reaching the other 3/4 area when it is necessary to cut it.

For example, if a blade with a width longer than the width of the support part 14 is used, at least all of the lower, inner, and upper surfaces One of the notches 14d is applied to the support portion 14d, and the support portion 14 can be easily cut alone or plurally by cutting upward or downward to apply a punching force. can in the resection at the same time, easy construction is Oh O ₀

 Next, referring to FIGS. 13A to 13D, the supporting portions 14 and 24, the connecting portion 26, and the first and second connecting portions 18 and 22 can be cut off. A unit-type combination in a pillar cut of a floor panel 10 including a notch 14 d formed by being connected in the form of a slit. The construction method is described.

First, in the first construction step, the floor panel 10 is cut by a cut 14d and shown by thick solid lines 101, 103 and 105 in FIGS. 13A to 13D. In accordance with the predetermined rules, the plurality of divided unit bodies al to a4, bto b4, cto c4, and dto d3, which are divided into predetermined sizes, are formed. You For example, as shown in Fig. 13A, the unit is divided into alunits al, a2, a3, and a4, and as shown in Fig. 13B, the unit body b1 is divided. , B2, b3, and b4, and as shown in FIG. 13C, into unity bodies c1, c2, c3, and c4, and Can be divided into unity bodies d1, d2 and d3 as shown in Figure 13D. These split unit bodies are floor mats. For example, the cell 10 is divided into four parts in a cross, four parts in a horizontal direction, three parts in an L-shape, three parts in a horizontal part, and the corners are cut off. Thick solid lines 101, 103 and 105 As shown, it has been cut and formed according to prescribed rules.

 Next, in the second construction step, each of the split units is so positioned that the connecting leg 24 and the connecting small projection 26 are not positioned outside the support portion 14. The connecting leg 24 and the connecting small protrusion 26 are connected to each other to form a connecting unit having a form different from that of the unit 1.

 More specifically, in the case of FIG. 13A, each of the divided unit bodies al, a2, a3, and a4, which are cut in a cross shape, is rotated by 180 degrees. Each is connected to each other by a connecting leg 24 and a connecting small projection 26 to form a connecting unit body as shown in FIG. 14A.

 Next, in the example shown in Fig. 13B, each of the divided unit bodies bl, b2, b3, and b4, which is divided into three parts in the horizontal direction and cut, is connected in the horizontal direction. It is formed by linking with. This is achieved by first connecting the unit bodies b2 and b3 laterally with the connecting legs 24 and the connecting small projections 26, and then causing the bl and b4 to face each other. The concatenated one is further connected to b3 in the horizontal direction. This forms a horizontally long connecting unit as shown in FIG. 14B. In this case, it can be effectively used for a residual space having a width of one panel 30 or a wall-side treatment.

In addition, the example shown in Fig. 13C is a divided unit body cl, c2, c3, and c4 that cuts the right side and the lower side. Are connected at a position that is symmetrical to the cut position. This is done by first connecting the unit bodies cl and c2 on the left side with the leg portions 24 and the small protrusions 26, then connecting the unit units cl and c3 on one side, and leaving the rest. By placing the remaining unit unit c4 in the upper left position as shown in the figure, a connected unit unit as shown in FIG. 14C is formed. This basically has the same shape as the connecting unit shown in FIG. 14A.

 In addition, the example shown in Fig. 13D shows the connection of divided unit units dl, d2 and d3, which are cut at the top and bottom and at the four corners. The legs 24 and the connecting small projections 26 are connected to both sides of the unit body dl at d2 and d3, and the remaining four corners are formed without connection. . This forms a rectangular connecting unit as shown in FIG. 14D.

 By such a construction method, a plurality of connected unit units are laid uniformly on the floor surface to form a floor panel structure.

 Here, after the second construction step, a third construction step as described below is added. In other words, in the third step, the main leg 14 and the auxiliary leg 16 as the first and second support portions are provided on each of the connecting unit units. A plurality of panels 30 are laid on each supporting portion so as to be supported by the floor panel, and a floor panel structure is formed.

By cutting such a supporting portion 14 by an arbitrary cutting method of the cutting portion 14d according to a predetermined rule as shown in FIGS. 13A to 13D, It is shown in Fig.14A ~ Fig.14D In this way, the connecting units 24 and the connecting small projections 26 having a different shape and / or area from the floor panel 10 are not extended. Can be obtained.

 As a result, when it is desired to connect to a predetermined remaining space portion or another floor panel, for example, a border panel for wall construction, it is necessary to lay it continuously. It can be constructed, and the processing of filling the remaining space near the wall can be easily performed.

 In addition, since the area can be changed, the work can be performed according to the laying area and the remaining area near the wall.

 In the description of the above-described embodiment, only four cutting methods are illustrated. However, the present invention is not limited to only these cutting methods. There are methods of cutting to imitate the notch, and various other cutting and linking methods.

 It should be noted that the embodiments described herein are for the purpose of illustrating the present invention, and modifications or modifications that can be made by those skilled in the art without departing from the spirit of the present invention. It goes without saying that is included in the scope of the present invention.
