Description

  The present invention relates to a panel frame to which an outer wall material or the like is attached.

  In Patent Document 1, a horizontal frame in a panel frame has vertical pieces on both sides, and a diaphragm thickness is formed between a pair of sandwiching pieces formed by projecting both vertical pieces at one end of the horizontal frame. Is inserted in order between the middle diaphragm portion of the vertical frame and the end diaphragm portion of the other horizontal frame, which are substantially the same as the thickness of the sandwiching piece, and the vertical frame and the other horizontal frame are fitted to both the sandwich pieces. A structure in which the device is joined is disclosed. If it is the structure which has the said edge part narrowing part, surface material attachment surfaces, such as an outer wall material, in a panel frame can be made flat.

JP-A-8-128133

  However, the conventional technique requires a processing operation for forming the end narrowed portion, and has a drawback that the manufacturing cost increases.

  In view of the above circumstances, an object of the present invention is to provide a panel frame in which a face material mounting surface can be made flat without forming the end diaphragm portion.

  In order to solve the above problems, a panel frame according to the present invention is a panel frame formed by connecting a plurality of frame members, and an insertion member provided between adjacent frame members, and a screw And a screw that is positioned so as not to protrude from the face material mounting surface by deforming the frame member by a portion being penetrated through the frame member and screwed into the insertion member. .

  With the above configuration, since the frame members are connected to each other by passing through the frame member and the screw portion of the screw is screwed into the insertion member, the panel frame can be easily manufactured and reduced. Cost can be reduced. Further, the screw head is positioned so as not to protrude from the face material mounting surface by deforming the frame member by the screwing, and thus the face material mounting surface can be made flat.

  A concave portion is formed on the surface side of the insert material into which the screw is screwed, and the deformed portion of the frame member enters the concave portion so that the head portion of the screw does not protrude from the face material mounting surface. You may make it locate in. According to this, the frame member can be easily deformed by the recess, and the head can be positioned so as not to protrude from the face material mounting surface.

  The insertion material having the concave portion may be entirely or partially made of steel. Steel is stronger than wood and can make the panel frame sturdy.

  By deforming the insert material, the deformed portion of the frame member may enter, and the head portion of the screw may be positioned so as not to protrude from the face material mounting surface. According to this, the process which forms the said recessed part can be omitted, and cost reduction can be carried out.

  In the configuration in which the insertion material is deformed, the specific gravity of the entire insertion material or the specific gravity of the surface layer portion on the surface side into which the screw is screwed is preferably 0.3 or more and 0.5 or less. According to this, the said insertion material can be deform | transformed reliably and can be located so that the said head may not protrude from the said face material attachment surface.

  In the configuration in which the insertion member is deformed, it is desirable that a screwless neck portion is formed on the screw with a length equal to or greater than the height of the head. According to this, the deformation of the insertion member is smoothly caused by the presence of the neck portion of the screwless, and the head can be surely positioned so as not to protrude from the face material mounting surface.

  Alternatively, the screw may be a full screw screw, and a pilot hole having a length equal to or greater than the height of the head may be formed on a surface side of the insertion material into which the screw is screwed. According to this, the deformation of the insertion member is smoothly caused by the presence of the pilot hole, and the head can be reliably positioned so as not to protrude from the face material mounting surface.

  If it is this invention, there exists an effect of being able to provide the panel frame which has a flat face material attachment surface at low cost.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
As shown in FIG. 1, the panel frame 1 according to this embodiment includes horizontal frame members 11 and 12 provided at the upper and lower portions, a central horizontal frame member 13 provided at the central portion, a left side and a right side. The vertical frame members 14 and 15 are provided. The horizontal frame member 11 provided in the upper part is provided across the vertical frame members 14 and 15 on the upper end side of the vertical frame members 14 and 15. Similarly, the horizontal frame member 12 provided in the lower part is provided across the vertical frame members 14 and 15 on the lower end side of the vertical frame members 14 and 15. The central horizontal frame member 13 is shorter than the horizontal frame members 11 and 12 and is provided so as to be sandwiched between the vertical frame members 14 and 15. These frame members 11, 12, 13, 14, 15 are made of lightweight channel steel having a U-shaped cross section (channel shape).

  The horizontal frame members 11, 12 and the vertical frame members 14, 15 are connected by an insert 2. The central horizontal frame member 13 is also connected to the vertical frame members 14 and 15 by the insert 2. The insertion material 2 is formed between the adjacent horizontal frame members 11 and 12 and the vertical frame members 14 and 15 and between the adjacent central horizontal frame member 13 and the vertical frame members 14 and 15. It is provided in the frame members 11, 12, 13, 14, and 15 (in the space between two opposing surface portions in a U-shaped cross section). The insertion material 2 is formed in, for example, a quadrangular prism shape, and is formed of wood, artificial wood, resin, or the like. Here, two opposing surface portions of the frame members 11, 12, 13, 14, and 15 form a frame surface of the panel frame 1, respectively, and one of the frame surfaces is attached with an outer wall material or the like. It is used as a face material mounting surface. The outer wall material or the like is fixed to the panel frame 1 with a drill screw or the like. Further, for example, after an outer wall base material is fixed to the panel frame 1 to form an outer wall of a building, paint or mortar may be applied to the outer wall base material.

  As shown in FIGS. 2, 3 (A), 3 (B), and 3 (C), the insert 2 is, for example, four on one side at both ends of the central lateral frame member 13. The central horizontal frame member 13 is fixed by a total of eight drill screws 3. Similarly, the insertion member 2 is fixed to the horizontal frame member 14 (15) at the center of the vertical frame member 14 (15) by, for example, a total of eight drill screws 3 of four on one side. . Similarly, in the horizontal frame members 11, 12, the vertical frame member 14 (15) is connected using the insertion material 2 and the drill screw 3.

  A screw portion 3a of the drill screw 3 passes through the frame members 11, 12, 13, 14, and 15 and is screwed into the insert member 2, and the countersunk head of the drill screw 3 is driven by the driving force of this screwing. The portion 3b deforms the frame members 11, 12, 13, 14, and 15 and is positioned below the face material mounting surface. That is, the head 3b is positioned so as not to protrude from the face material mounting surface. In this embodiment, when the insert 2 is deformed, the deformed portions of the frame members 11, 12, 13, 14, 15 enter the insert 2, and the head 3 b of the drill screw 3 is Located below the face material mounting surface. That is, the head 3b sinks below the face material mounting surface. The specific gravity of the insert 2 is, for example, 0.3 or more and 0.5 or less in order to facilitate the deformation.

  As shown in FIG. 4, the drill screw 3 has the screw portion 3a, the head portion 3b, and a neck portion 3c. The neck portion 3c is a screwless portion where a screw is not cut. Further, the length L of the neck portion 3c is equal to or greater than the height a of the head portion 3b.

  If it is said structure, the said frame members will be joined by the thread part 3a of the said drill screw 3 penetrating the said frame members 11, 12, 13, 14, and 15 and being screwed in the said insertion material 2. Therefore, the panel frame 1 can be easily manufactured and the cost can be reduced. Further, the head 3b of the drill screw 3 is positioned below the face material mounting surface by deforming the frame members 11, 12, 13, 14, and 15 by the driving force of the screwing, so a machine such as a press machine is required. The surface material mounting surface can be made flat without taking time and effort.

  The specific gravity of the entire insertion material 2 is not limited to 0.3 or more and 0.5 or less, and the surface layer portion on the surface side into which the drill screw 3 is screwed (see, for example, a two-dot chain line in FIG. 4). The specific gravity may be 0.3 or more and 0.5 or less, and the portion other than the surface layer portion may be made of wood or the like having a specific gravity greater than 0.5. The thickness of the surface layer portion is, for example, not less than the height a.

  Further, as shown in FIGS. 5A and 5B, the insertion material 2 may be constituted by a core material 21 and two surface layer materials 22. The core material 21 is formed by bending a steel material into a U-shaped cross section, for example, and the surface layer material 22 is provided outside two opposing face portions in the U-shaped cross section of the core material 21. The surface layer material 22 is made of, for example, wood, artificial wood, resin, or the like, and has a thickness of, for example, the height a or more.

  Further, as the drill screw 3, it is also possible to use an all screw type drill screw without the screwless neck portion 3c. Further, when such an all-screw type drill screw is used, a diameter larger than the valley diameter of the screw portion 3a, preferably larger than the outer diameter, is provided on the surface into which the drill screw 3 of the inner insert 2 is screwed. It is desirable to form a pilot hole. The depth of the pilot hole is, for example, not less than the height a.

  Moreover, as shown to FIG. 6 (A), FIG. 6 (B), and FIG. 6 (C), the panel frame 1 can also be comprised using the insertion material 4. As shown in FIG. The insert 4 is formed by bending a steel plate into a U-shaped cross section, for example. And the two surface parts which oppose in the cross-sectional U-shape of this insertion material 4 are made into the surface into which the said drill screw 3 is screwed. A concave portion 4a into which a deformed portion of the frame member 11, 12, 13, 14, 15 generated by the screwing is formed is formed at a position where the drill screw 3 of the surface portion is screwed. The frame members 11, 12, 13, 14, 15 can be deformed to position the head 3 b below the face material mounting surface. The recess 4a is formed in, for example, a triangular or trapezoidal mortar shape or a groove shape having a triangular or trapezoidal cross-sectional shape. The depth of the recess 4a is, for example, not less than the height a.

  Even in the configuration using the insertion member 4 in which the recess 4 a is formed, the screw part 3 a of the drill screw 3 is screwed into the insertion member 4 through the frame members 11, 12, 13, 14, 15. Thus, since the frame members are joined to form a frame, the panel frame 1 can be easily manufactured and the cost can be reduced.

  Furthermore, when the said insertion material 4 consists of steel materials, joining part intensity | strength improves and fire resistance performance also improves.

  As shown in FIG. 7A, FIG. 7B, and FIG. 7C, the insert 4 is made of block-like wood, artificial wood, resin, etc. The surface portion may have a recess 4a. The depth of the recess 4a is, for example, not less than the height a.

  Further, as shown in FIGS. 8A, 8B, and 8C, the interpolating material 4 may be composed of a core material 41 and two surface layer materials 42. For example, the core material 41 is formed by bending a steel plate into a U-shaped cross section, and the surface layer material 42 is provided outside two opposing face portions in the U-shaped cross section of the core material 41. The surface layer material 42 is made of, for example, wood, artificial wood, resin, or the like, and the depth of the recess 4a is, for example, not less than the height a.

  As the drill screw 3 to be screwed into the concave portion 4a of the insertion member 4, an all screw type drill screw 3 without a screwless neck portion 3c can be used. Also good.

The plate thickness of the frame members 11, 12, 13, 14, and 15 is, for example, 2.3 mm or less, preferably 1.6 mm or less, from the viewpoint of ease of deformation by screwing the drill screw 3. The lower limit of the plate thickness is determined from the viewpoint of strength to be provided as a panel frame. The frame member 11 and the like are preferably made of, for example, SS400 class (for example, SS400, SSC400) of JIS (Japanese Industrial Standard) from the viewpoint of ease of deformation by screwing the drill screw 3. The frame member 11 and the like preferably have a yield point that is less than the tensile strength of the drill screw 3 to be used. For example, when the tensile strength of the drill screw 3 to be used is 450 N / mm ² which is the smallest strength section, it is desirable to use a steel material having a yield point of 450 N / mm ² or less as the frame member 11 or the like. .

  Further, a through hole may be formed in the frame member 11 or the like, and the drill screw 3 may be screwed through the through hole. The diameter of the through hole may be smaller than the diameter of the screw portion 3a of the drill screw 3. When the through hole is formed, a general screw can be used.

  In the embodiment described above, the head 3b is positioned below the frame surface on both of the two frame surfaces in the panel frame 1, that is, the frame surface on the side that is not the face material mounting surface. It is not always necessary to position the head 3b below the frame surface on the frame surface that is not the face material mounting surface.

  As mentioned above, although embodiment of this invention was described with reference to drawings, this invention is not limited to the thing of embodiment shown in figure. Various modifications and variations can be made to the illustrated embodiment within the same range or equivalent range as the present invention.
