Description

  The present invention relates to a mounting structure for a roof material such as a metal roof material.

  Conventionally, a roof is formed by laying a plurality of roofing materials vertically and horizontally on a roof base, but in this case, the roof adjacent in the horizontal direction (direction perpendicular to the water flow direction of the roof) The material is trying to secure the waterproofness of the roof by overlapping the side edges of the material. For example, as shown in FIG. 16, the roof material A described in Patent Document 1 forms a substantially flat cover portion 20 at one side end portion, and has a substantially wavy cross section at the other side end portion. A plate portion 21 is formed, and two roofing materials are formed so that a cover portion 20 of another roofing material A is covered on the discarding plate portion 21 of the roofing material A laid on the roof base 6. A and A are laid adjacent to each other in the horizontal direction. However, in the roof material A described above, from the viewpoint of waterproofing, the cover portion 20 and the discard plate portion 21 are formed to have a certain length, and the cover portion 20 and the discard plate portion 21 are overlapped to connect the roof material A. Therefore, the roof material must be cut to adjust the dimensions at the loose part of the roof base 6, the falling ridge, or the boundary part (wall rising part) between the roof base 6 and the wall of the second floor part. There was a possibility that the waste material of the roofing material was generated at the construction site. Moreover, since the cover part 20 is always put on the discard board part 21, the direction in which the roofing material is laid is limited to one of the left to right or right to left directions of the roof base, and the workability is improved. There was a risk of decline.

Japanese Patent Laid-Open No. 11-159066

  In view of this, the present applicant has proposed a roofing material having a connection portion having a substantially wavy cross section at both side end portions (Japanese Patent Application No. 2009-3473). In this case, as shown in FIG. 17, the dimension adjustment is performed by appropriately adjusting the overlapping length of the side end portions of the roofing material A adjacent in the lateral direction (direction orthogonal to the water flow direction) according to the construction site. It is not necessary to cut the roofing material for this purpose, and there is no particular restriction on which roofing material is placed on the right or left of the adjacent roofing material and which roofing material is placed on the bottom. The direction of laying is not limited to one direction.

  Further, the roof material A adjacent in the vertical direction (water flow direction) is connected by locking the locked portion 4 and the locking portion 5. The to-be-latched part 4 is formed in the underwater side edge part (for example, eaves side edge part) of the roof material main body 1, Comprising: The said extension extended in the underwater side edge part of the roof material main body 1 A part of the metal plate is bent so as to be folded back to the back side of the underwater side end portion of the roofing material body 1, thereby forming the roofing material body 1 over substantially the entire length in the lateral direction. Moreover, the latching | locking part 5 is formed in the water-side edge part (for example, ridge side edge part) of the roof material main body 1, Comprising: The said metal extended in the water-side edge part of the roof material main body 1 By bending a part of the plate so as to be folded back to the surface side of the water-side end of the roofing material body 1, the cross-section consisting of the upper piece 5 a and the lower piece 5 b over the substantially entire length in the lateral direction of the roofing material body 1. It is formed in an inverted U shape. The fixed piece 10 is formed of a part of the metal plate protruding from the water-side end of the locking portion 5. The fixed piece 10 is formed over substantially the entire length in the horizontal direction of the roof material main body 1, and the vertical cross-sectional shape is formed in a substantially reverse letter shape, from the upper piece 5 a of the locking portion 5 toward the water side. Projecting.

  Then, when connecting the roof materials A and A adjacent in the vertical direction, first, the roof material A disposed under the water is attached to the roof base 6. In this case, as shown in FIG. 18, the attachment strength of the roof material A is reinforced and fixed by using the suspension B. The hanging element B is formed by a fitting part 30 having a substantially inverted U-shaped cross section and a fixing part 31 protruding from the upper end of the fitting part 30 toward the water side. Such a hanging element B fits the fitting part 30 on the surface side (outside) of the locking part 5 and arranges the fixing part 31 on the surface side (upper side) of the fixing piece 10. The roof material A and the suspension B are fixed to the roof base 6 by driving a fixing tool 32 such as a screw into the roof base 6 from the upper side of the fixing portion 31 so as to penetrate 10. The suspension B can be provided at a pitch of about 900 mm in the lateral direction. Thereafter, the locked portion 4 of the roof material A disposed on the water side is locked to the locking portion 5 of the above-described roof material A on the water side. In this case, the locked portion 4 of the roof material A on the upper side is inserted between the locking portion 5 of the roof material A on the lower side and the roof material main body 1, and the lower side of the locking portion 5 is engaged. The stop 4 is locked. The hanger B is in a state in which the surface side (outside) is covered with the engaged portion 4 and the underwater end portion of the roof material body 1.

  In this way, the portion where the hanging element B is provided is fixed for fixing a functional member such as a photovoltaic power generation panel because the locking portion 5 is covered and reinforced by the fitting portion 30 along its outer shape. Member C can be attached.

  However, since the above-mentioned hanging element B has a thickness of about 1.2 mm and is thicker than the roofing material A, and is provided so as to protrude from the outer surface of the locking portion 5, the surface of the roofing material A fixed by the hanging element B When a plurality of roofing materials A arranged on the side are connected in the horizontal direction, there is a problem that the side edge 1a of the roofing material A hits the hanger B and interferes with it, so that the construction of the roofing material A is difficult to perform. .

  This invention is made | formed in view of said point, and it aims at providing the attachment structure of the roof material which construction is easy to perform.

The roof material mounting structure of the present invention is provided with a locking portion 5 projecting to the surface side of the roof material body 1 at the water-side end portion of the substantially flat roof material body 1 and the water-side end of the roof material body 1. The roof material A is formed by providing the locked portion 4 protruding to the back side of the roof material main body 1 at the part, and among the roof materials A and A adjacent in the water flow direction, The to-be-latched part 4 is latched by the latching | locking part 5 of the roof material A under water, and the side of one roofing material main body 1 among the roofing materials A and A adjacent in the direction orthogonal to the water flow direction. An attachment structure of the roof material A whose end is overlapped and connected to the other roof material main body 1, wherein the locking portion 5 includes an upper piece 5 a and a lower piece 5 b and has a substantially inverted U-shaped cross section. is formed, the reinforcing member 40 inside the locking portion 5 is provided, the reinforcing member 40 is disposed along the upper surface of the lower piece 5b, the engaged portion 4 before Is characterized in that the composed locked to the lower surface of the lower piece 5b.

  In the present invention, the reinforcing member 40 is preferably fixed to the roof base 6.

  In the present invention, a waterproof portion 41 is formed on the roof material main body 1 so as to be substantially perpendicular to the surface at the water-side end of the roof material A closest to the ridge portion of the roof base 6. It is preferable that the packing 42 is provided on the surface of the roof material main body 1 on the underwater side.

  In the present invention, the reinforcing member 40 can be prevented from projecting to the outer surface of the locking portion 5, and the roof material on the water side is connected when connecting the adjacent roof materials A and A in the direction orthogonal to the water flow direction. The locked portion 4 and the side edge portion 1a of A do not hit the reinforcing member 40, so that the construction can be easily performed.

  Hereinafter, modes for carrying out the present invention will be described.

  The roof material A used in the present invention can be formed into a desired shape by processing a metal plate by roll forming or the like. As the metal plate, for example, a metal plate having a thickness of 0.3 to 0.5 mm can be suitably used. As the type of the metal plate, various types such as a coated steel plate, a galvanized steel plate, and a Galvalume steel plate (registered trademark) are used. Can be used. In addition, for manufacturing, conventionally, the roll forming machine can only be used, but the roofing material A used in the present invention has almost no R processing (curved surface processing), and can be handled by a bender processing machine. It can be handled by hemming bending and pressing.

  As shown in FIG. 2, the roof material A used in the present invention is formed to be bilaterally symmetric (line symmetric), and includes a roof material main body 1, a locked portion 4, a locking portion 5, and a fixed piece 10. Etc. are formed.

  The roof material main body 1 is formed long in the lateral direction (direction orthogonal to the water flow direction of the roof), and the length L1 in the lateral direction can be, for example, a standard length of about 2000 mm. The working width L2 of the material main body 1 in the vertical direction (the water flow direction of the roof) can be set to, for example, 200 to 280 mm, and preferably about 250 mm. A plurality of protrusions 2 are formed substantially parallel to both side end portions of the roofing material body 1. The protrusion 2 can be formed by a groove having a substantially V-shaped cross section that opens on the surface of the roofing material body 1 by rib processing or the like. Is formed over. The protrusion 2 can have a width of 4 to 10 mm, a depth from the surface of 0.5 to 1.5 mm, and a length of 180 to 280 mm, for example. It is preferable to form the protrusion part 2 in the range of the width dimension L3 = 100-200 mm from the side edge part 1a of the roofing material main body 1. FIG. The protrusion 2 may be formed so as to protrude from the surface of the roofing material body 1, and both the protrusion 2 protruding from the surface of the roofing material body 1 and the protrusion 2 protruding from the back surface are formed. Also good. The side edge 1a of the roofing material body 1 is bent to make it difficult to see the edge from the outside in order to improve rust prevention and rigidity.

  Further, a positioning portion 3 is formed on the roof material main body 1. The positioning portion 3 is formed in a substantially inverted V-shaped cross-section that opens on the back surface of the roofing material body 1 by rib processing or the like, protrudes from the surface of the roofing material body 1 and extends over the substantially entire length of the roofing material body 1 in the vertical direction. Is formed. Moreover, the positioning part 3 can be provided in the both sides of the roof material main body 1 one by one or plural pieces. When one positioning part 3 is provided on each side of the roofing material body 1, the positioning part 3 can be formed at a position of a predetermined dimension from the side edge 1 a of the roofing material body 1, for example, the side edge of the roofing material body 1. The positioning part 3 can be formed at a position 100 mm from the edge 1a. In addition, when a plurality of positioning portions 3 are provided on both sides of the roof material main body 1, the positioning portions 3 can be formed at regular intervals from the side edge 1 a of the roof material main body 1. The positioning part 3 can be formed at an interval of 100 mm from the edge part 1a. The positioning portion 3 may be formed in any shape or position as long as it can be visually recognized.

  The to-be-latched part 4 is formed in the underwater side edge part (for example, eaves side edge part) of the roof material main body 1, Comprising: The said extension extended in the underwater side edge part of the roof material main body 1 By bending a part of the metal plate so as to be folded back to the back side of the underwater side end portion of the roof material main body 1, the roof plate main body 1 can be formed over substantially the entire length in the lateral direction.

  The locking portion 5 is formed at the water-side end portion (for example, the ridge-side end portion) of the roof material main body 1 and extends from the water-side end portion of the roof material main body 1. By bending a part so as to be folded back to the surface side of the water-side end portion of the roof material main body 1, the cross-section of the upper piece 5a and the lower piece 5b is substantially inverted over substantially the entire length of the roof material main body 1 in the lateral direction. It can be formed in a letter shape. Therefore, the locking part 5 is formed to protrude from the water-side end of the roofing material body 1 toward the waterside above the roofing material body 1, and the water-side end of the locking part 5 is closed, The cross section is formed in a substantially inverted U shape so that the water side of the locking portion 5 is opened.

  The fixing piece 10 can be formed by a part of the metal plate protruding from the water-side end of the locking portion 5. The fixed piece 10 is formed over substantially the entire length in the horizontal direction of the roof material main body 1, and the vertical cross-sectional shape is formed in a substantially reverse letter shape, from the upper piece 5 a of the locking portion 5 toward the water side. Projecting.

  And the above-mentioned roof material A is laid in the vertical and horizontal directions on a roof base 6 such as a field plate, whereby a roof can be formed. In this case, the roofing materials A and A are laid adjacent to each other and are connected to ensure attachment strength and improve waterproofness.

  As shown in FIG. 3, the roofing materials A and A that are adjacent in the horizontal direction overlap the side ends of the roofing material main body 1 up and down, or the side end of the roofing material main body 1 of one roofing material A. The other roofing material A is connected to the roofing material main body 1 by being superimposed one above the other. Here, since the cross-sectional shape of the roof material A in the vertical direction is substantially constant over the entire length in the horizontal direction, the overlapping dimension can be arbitrarily set, and in order to ensure waterproof performance, Although it is preferable to overlap 100 mm or more from the edge 1a, the overlapping dimension can be changed according to the adjustment of the size of each part of the roof. In addition, although the upper limit of the dimension to overlap is not set in particular, since a useless part will increase in the roofing material A if it is too large, the dimension to overlap is less than half of the horizontal dimension from the side edge part 1a of the roofing material main body 1. It is preferable to set it to 200 mm or less. Further, since the roof material A is symmetrical, it is possible to overlap both the left and right roof materials A and A adjacent in the horizontal direction, and from either the left or right direction of the roof base 6 in the horizontal direction. It can be laid sequentially.

  And the clearance gap S can be provided by the projection part 2 between the roof materials A and A which overlapped up and down. That is, as shown in FIG. 4A, the protrusion 2 provided on the upper roof material A is placed on the flat portion of the surface of the roof material body 1 of the lower roof material A, so that the lower side A gap S can be formed between the surface of the roof material body 1 of the roof material A and the back surface of the roof material body 1 of the upper roof material A. Usually, rainwater flows on the surface of the roofing material A, and rainwater does not enter the gap S. However, in the unlikely event that rainwater falls under the roofing material A on the upper side in the overlapping portion of the roofing materials A and A adjacent in the lateral direction. Even when it enters, rainwater can be drained through the gap S. Therefore, it is preferable that the protrusions 2 of the roofing materials A and A that overlap in the vertical direction do not overlap with each other in order to form the reliable gap S. In addition, when the protrusion part 2 protrudes on the surface of the roof material main body 1, the roof material main body 1 of the upper roof material A is formed on the upper end of the protrusion part 2 provided on the roof material main body 1 of the lower roof material A. By placing the flat portion on the back surface of this, a gap S similar to the above can be formed. Moreover, the roof materials A and A adjacent in the vertical direction are connected by overlapping a part thereof vertically. In this case, the locked portion 4 of the roof material A laid on the water side (for example, the ridge side) is locked to the locking portion 5 of the roof material A laid on the water side (for example, the eave side). .

  Here, the connection of the roof materials A and A in the horizontal direction and the vertical direction will be described in detail. First, the roof material A is placed on the roof base 6 with the locking portion 5 extended upward, and a fixing tool 11 such as a screw is driven into the fixing piece 10 and the roof base 6 to fix the fixing piece 10. By fixing the fixing piece 10 in this manner, the shape can be fixed (determined) in a state where the engaging portion 5 is contracted up and down to reduce the vertical dimension (thickness). Here, the reinforcing member 40 is also fixed to the roof base 6. The reinforcing member 40 is made of metal or the like, and has a flat plate-like fixing portion 40a, an upper piece support portion 40b having an approximately L-shaped cross section that protrudes substantially vertically upward from the water-side end of the fixing portion 40a, A lower piece reinforcing portion 40c that protrudes obliquely upward from the water-side end portion of the piece support portion 40b is formed in a piece shape. And the reinforcement member 40 inserts the upper piece support part 40b and the lower piece reinforcement part 40c inside the latching | locking part 5, ie, between the upper piece 5a and the lower piece 5b from the water side of the latching | locking part 5. The fixed portion 40a is disposed below the fixed piece 10 of the roof material A. Here, the lower piece reinforcement part 40c is arrange | positioned along the upper surface of the lower piece 5b, and, thereby, the lower piece 5b can be reinforced with the lower piece reinforcement part 40c. The upper piece support portion 40b is located immediately below the upper piece 5a, and supports the upper piece 5a when it is deformed downward. The fixing portion 10 a is fixed to the roof base 6 by the fixing piece 11 being driven together with the fixing piece 10. The reinforcing members 40 can be provided in the lateral direction of the roof material A, for example, at a pitch of 900 mm.

  Next, another roof material A is placed side by side on the fixed roof material A. At this time, as described above, the adjacent roofing materials A and A are connected by being superposed vertically while being shifted in the lateral direction. Moreover, when the locking part 5 of the fixed roofing material A is inserted from the water side between the upper piece 5a and the lower piece 5b of the locking part 5 of the newly arranged roofing material A, FIG. As shown in Fig. 2, the surface of the fixed portion 10 of the fixed roofing material A is covered with the engaging portion 5 of the roofing material A to be newly arranged on the surface of the fixed portion 5 of the fixed roofing material A. The fixed piece 10 of the roof material A to be newly arranged is put on. Next, as shown in FIG. 5 (b), the newly placed roof is formed by driving a fixing tool 11 into the newly-fixed roof material A fixing piece 10 and the fixed roof material A fixing piece 10. The fixing piece 10 of the material A is fixed. And, when covering the locking portion 5 of the roof material A to be newly placed on the surface of the locking portion 5 of the fixed roof material A, the reinforcing member 40 does not protrude from the surface of the locking portion 5, It is easy to cover.

  In this way, after laying a plurality of roofing materials A, A ... in a horizontal row, another plurality of roofing materials A, A ... are sequentially laid in a horizontal row above the laid roofing material A. Go. At this time, as shown in FIG. 5 (c), the locked portion 4 of the roof material A on the upper side is connected to the roof material body 1 and the locked portion of the roof material A (the roof material covered on the upper side) A. The inserted locked portion 4 is locked to the lower surface of the locking portion 5. At this time, since the reinforcing member 40 does not protrude from the surface of the locking portion 5, the locked portion 4 can be easily inserted between the roof material body 1 and the locking portion 5. Thereafter, as shown in FIG. 5 (d), the locked portion 4 of the other roof material A on the upper side is further replaced with the locked portion 4 of the roof material A on the upper side and the roof material A on the lower side. By being inserted between the roof material main body 1 and the roof material body 1, the water is locked to the locking portion 5 of the roof material A on the underwater side. Thus, in the location where the four roof materials A are adjacent to each other in the vertical direction and the horizontal direction, the two locked portions 4 and 4 and the two locking portions 5 and 5 are finally overlapped. . In this way, a roof can be formed by laying a plurality of roof materials A vertically and horizontally.

  And in the attachment structure of the roofing material A of this invention, when the roofing materials A and A adjacent to the horizontal direction are piled up and down, the positioning part 3 is made into a guide (guideline). For example, as shown to Fig.4 (a), the positioning part 3 provided in one roofing material A among the roofing materials A and A adjacent to a horizontal direction, and the side edge part 1a of the other roofing material A, and To overlap. Thus, the overlapping position of the roof materials A and A adjacent in the lateral direction can be adjusted using the positioning portion 3 as a guideline, and thus the roof materials A and A adjacent in the horizontal direction are overlapped on each other. The boundary line (joint) L between the side edge 1a of the roofing material body 1 of the roofing material A and the surface of the roofing material body 1 of the roofing material 1 positioned below can be easily aligned regularly throughout the roof. Therefore, for example, as shown in FIG. 6, the roof materials A and A adjacent in the horizontal direction are overlapped and connected so that the boundary line L of the roof materials A and A adjacent in the vertical direction is aligned. As a result, irregular joints are less likely to be formed on the roof, and the appearance of the roof is less likely to deteriorate.

  In addition, when a plurality of positioning portions 3 are formed at both side end portions of the roof material main body 1, as shown in FIG. 4 (b), one of the roof materials A and A adjacent in the lateral direction. The positioning portion 3 provided on the roof material A and the side edge portion 1a of the other roof material A can be overlapped, and the other remaining positioning portions 3 can be overlapped. Note that the side edge 1a of the roofing material body 1 is bent so as to be inclined obliquely downward in order to have an appearance approximate to the protrusion 2 in plan view. Therefore, an appearance similar to that of the boundary line L is expressed by the protrusions 2 so that the boundary line L is not noticeable.

  Since the roofing material A of the present invention does not have a portion perpendicular to the surface of the roofing material main body 1 in the locked part 4 or the locking part 5, the side end of the roofing material A protrudes upward. It can be easily folded at a substantially right angle. Accordingly, in the storage structure of the boundary portion between the roof base 6 and the rising wall, the side end portion of the roof material A is bent upward at a substantially right angle so as to be along the surface of the rising wall and the adjacent roof materials A and A are overlapped. By adjusting the dimensions, the roof material A is not cut, and the generation of waste materials at the construction site can be minimized. In addition, since the present invention has a shape that can be easily bent as described above, it can be laid in a descending ridge along the surface of the roof base 6 without cutting. That is, when the long surface 6a and the short surface 6b of the roof base 6 are adjacent to each other via the descending ridge 6c, first, as shown in FIG. 7B, a plurality of roof materials A, A. Are laid in the lateral direction and from the eaves side toward the ridge side, but the side edge on the short surface 6b side of the roofing material A laid in the portion closest to the short surface 6b is bent to follow the surface of the short surface 6b. To be arranged. Next, as shown in FIG. 7C, a plurality of roofing materials A, A... Are laid on the short surface 6b from the lateral direction and from the eaves side to the ridge side, but are closest to the long surface 6a. The side end portion on the long surface 6a side of the roof material A laid on the part is bent and arranged along the surface of the roof material A laid on the long surface 6a. Thereafter, as shown in FIG. 7 (a), the roof material A can be constructed by attaching the cover material 13 having a substantially square cross section to the descending ridge 6c and the ridge 6d. And, as shown in FIG. 7 (a), as in the case of construction at the boundary between the roof base and the rising wall, the roof material A can be adjusted and stored without cutting, Generation of waste materials at the construction site can be minimized. Moreover, as shown in FIG.7 (c), when the roofing material A of this invention is constructed in the short surface 6b, as it rolls up from the eave side to the ridge side, it overlaps and shows the overlapping part K (it shows with a dotted pattern). Although the dimension becomes longer, when the construction is performed on the long surface 6a, the dimension of the overlapped portion K is constant and can be accommodated without being cut.

  The roof material A can be bent in advance according to the shape of the roof, not at the construction site but at a factory or the like. The roof base 6 on which the roofing material A is constructed has an error between the design dimensions described in the drawings and the actual dimensions actually measured at the construction site, and conventionally, the roofing material A at the construction site according to the actual dimensions. Therefore, it is difficult to process the roof material A in advance at a factory or the like. However, in the present invention, the roofing materials A and A that are adjacent in the lateral direction are overlapped and constructed, so that the above error can be absorbed by adjusting the overlapping dimension. Therefore, the roofing material A can be processed in advance in the factory according to the design dimensions to make a pre-cut product, and the construction time can be greatly shortened and the roofing material can be accurately obtained without depending on the technique of the installer. A can be finished.

  And in said roof material A, since it can adjust freely the overlapping dimension (spreading leg) of the adjacent roof materials A and A, it is a dimension in a gap part, a descending ridge part, and a wall raising part from a plane part. Construction can be done without cutting the roof material body 1 for adjustment. Therefore, the workability can be greatly improved by adjusting the overlapping dimension after bending the end portion without focusing on the dimension adjustment at the site. Further, in the present invention, since there is no cutting work, it is a construction method that generates as little waste as possible on site. In the case of the short roof material A, cutting is necessary. However, if the length is also adjusted at the factory, cutting is not necessary at the site, and no waste material can be obtained. In addition, the roofing material A used in the loose portion, the descending ridge portion, and the wall raising portion can be processed in advance and delivered to the site, thereby saving the labor of the field work and further improving the workability. Moreover, since the roof material A of the present invention has a simple and nearly flat shape, the roof material A can be constructed without cutting by bending the roof material A around the ridge line in the ridge. In addition, since the shape of the roof material A of the present invention is simple, it is not necessary to process after sheet metal work (unnecessary portion cutting), and workability can be improved. Moreover, even if the length of the roofing material A of the present invention is fixed, it is possible to cope with the order by placing a quantity considering the roof area and the overlap allowance without the need for on-site measurement, and facilitating estimation and integration work. . Moreover, the roofing material A of the present invention is bilaterally symmetric and can be sown from either the left or right side, and even when cut in half, it can be put in a loose part or a descending ridge part to bring the cut surface to the surface. It can be stored without any additional cost, and can be efficiently sown without taking up an extra allowance. In addition, the receiving member (cover material) of the descending ridge part and the ridge part also has a simple shape, and the storage of the intersections and joints can be overlapped as it is, and the length can be adjusted in the same way as the roofing material A. It can be reduced as much as possible.

  Moreover, as shown in FIG. 1, the fixing member C for fixing functional members, such as a photovoltaic power generation panel, can be attached in the location which provided the reinforcement member 40. As shown in FIG. The fixing member C includes a base portion 60 and a sandwiching piece 61 and is formed in a substantially C-shaped cross section. The fixing member C is provided with a fastener 62 such as a bolt that penetrates the base portion 60 and the sandwiching piece 61 up and down. A screwing tool 63 such as a nut is screwed onto 62 at the upper side of the clamping piece 61. And between the roofing material main body 1 and the latching | locking part 5 in which the to-be-latched part 4 was inserted, the front-end | tip of the base part 60 was further inserted, and the roof material A of the water side which inserted the to-be-latched part 4 was inserted. By engaging the clamping piece 61 with the upper surface of the roof material main body 1 and screwing the screwing tool 63 into the fastening tool 62, the locked part 4, the locking part 5, and the base part 60 and the clamping piece 61. The reinforcing member 40 is sandwiched. Thereby, the fixing member C can be attached to the roofing material A. And since the reinforcement member 40 is provided inside the latching | locking part 5, it becomes difficult to produce the deformation | transformation and damage of the latching | locking part 5 or the to-be-latched part 4, and the fixing member C can be attached stably.

The contact can be strengthened by the elastic force of the locked portion 4, a waterproof line can be formed reliably, and the locking between the locking portion 5 and the locked portion 4 can be strengthened.

  The roofing materials A and A having the locking part 5 and the locked part 4 shown in FIG. 13 can also be connected vertically and horizontally in the same manner as in FIG. First, the roof material A is placed on the roof base 6 with the locking portion 5 extended upward, and a fixing tool 11 such as a screw is driven into the fixing piece 10 and the roof base 6 to fix the fixing piece 10. By fixing the fixing piece 10 in this manner, the shape can be fixed (determined) in a state where the engaging portion 5 is contracted up and down to reduce the vertical dimension (thickness). Next, another roof material A is placed side by side on the fixed roof material A. At this time, as described above, the adjacent roofing materials A and A are connected by being superposed vertically while being shifted in the lateral direction. Moreover, as shown to Fig.14 (a), the roof part A of the roof material A which is newly arrange | positioned is covered on the surface of the latching part 5 of the fixed roof material A, and the fixed roof material The fixed piece 10 of the roof material A to be newly arranged is placed on the surface of the fixed piece 10 of A. Next, as shown in FIG. 14 (b), the newly placed roof is formed by driving a fixture 11 into the newly-fixed roof material A fixing piece 10 and the fixed roof material A fixing piece 10. The fixed piece 10 of the material A is fixed to the roof base 6.

  In this way, after laying a plurality of roofing materials A, A ... in a horizontal row, another plurality of roofing materials A, A ... are sequentially laid in a horizontal row above the laid roofing material A. Go. At this time, as shown in FIG. 14 (c), the locked portion 4 of the roof material A on the upper side is connected to the roof material main body 1 and the locked portion of the roof material A (the roof material covered on the upper side) A. The inserted locked portion 4 is locked to the lower surface of the locking portion 5. Thereafter, as shown in FIG. 14 (d), the locked portion 4 of the other roof material A on the water side is further replaced with the locked portion 4 of the roof material A on the water side and the roof material A on the water side. By being inserted between the roof material main body 1 and the roof material body 1, the water is locked to the locking portion 5 of the roof material A on the underwater side. Thus, in the location where the four roof materials A are adjacent to each other in the vertical direction and the horizontal direction, the two locked portions 4 and 4 and the two locking portions 5 and 5 are finally overlapped. . In this way, a roof can be formed by laying a plurality of roof materials A vertically and horizontally.

  FIG. 15 shows another embodiment. In this roof material mounting structure, the reinforcing member 40 shown in FIG. 1 is provided with a spacer piece 70, and the other configurations are the same as described above. As shown in FIGS. 15B and 15C, the spacer piece 70 is integrally bent at both end portions of the upper piece support portion 40 b of the reinforcing member 40. Further, the spacer piece 70 is formed so as to protrude to the front side of the fixed portion 40a and to be positioned below the lower piece reinforcing portion 40c. Further, the front end portion of the spacer piece 70 projects forward from the front end of the lower piece reinforcing portion 40c, and a spacer protrusion 71 having a height of about 3 mm is provided on the upper surface of the front end portion of the spacer piece 70.

  And also when constructing roofing material A using such a reinforcing member 40, it can carry out similarly to the said FIG. 1, However, The spacer piece 70 is the roofing material arrange | positioned under water rather than the reinforcing member 40. It is located between the lower surface of the roof material body 1 of A and the upper surface of the roof base 6. Here, the surface of the roof base 6 is covered with a roofing material 72, and the spacer piece 70 is located between the lower surface of the roofing material body 1 and the upper surface of the roofing material 72. Accordingly, the roof material A is lifted from the upper surface of the roofing material 72 by the sum of the thickness of the spacer piece 70 (for example, 1.2 mm) and the height of the spacer protrusion 71, and the lower surface of the roofing material body 1 and the roofing material. A space (gap) SP corresponding to the sum of the thickness of the spacer piece 70 (for example, 1.2 mm) and the height of the spacer protrusion 71 is generated between the upper surface of 72. Therefore, even if water leaks to the lower side of the roof material A, the water is drained to the eaves through the space SP along the surface of the roofing material 72. In the conventional roofing roof material, the roofing material and the roofing surface are in close contact with each other, and water is dammed there, so that water cannot be smoothly drained to the eaves and water is collected inside the roof. In the long term, if the moisture state continues, there is a risk that the base plate and the roofing material will deteriorate. However, with the structure shown in FIG. 15, it is difficult for water to collect inside the roof, leading to reduction of deterioration.

  Further, when the spacer projection 71 is pressed against the roof material main body 1 of the roof material A that covers the spacer projection 71, the roof material main body 1 is deformed into a convex shape so as to protrude on the surface according to the shape of the spacer projection 71. Will be. And the position of the reinforcement member 40 can be easily recognized using this convex deformation part as a mark. Therefore, the fixing member C can be accurately arranged at the insertion position of the reinforcing member 40. In particular, even when the fixing member C is attached at a certain time after construction of the roof material A, the attachment position of the fixing member C is easily understood and effective.
