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

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

  As shown in FIG. 1, the metal roof material A of the present invention includes a roof material main body 1 formed in a substantially flat plate shape, and a connection portion 3 formed at the side end portions of both side portions 2 of the roof material main body 1. And a fitting part 4 formed at the eaves side end of the roof material main body 1, a fitted part 5 formed at the ridge side end of the roofing material main body 1, and a ridge side end of the fitted part 5 And a fixed piece 10 protruding from the portion.

  The roof material main body 1 is formed long in the lateral direction (direction orthogonal to the roof gradient), and as shown in FIG. 2A, the lateral length L1 is, for example, a standard length of about 2000 mm. Moreover, the working width L2 of the vertical direction (roof gradient direction) of the roofing material main body 1 can be about 200 mm as shown in FIG.2 (b), for example. The connecting portion 3 is formed over substantially the entire length in the longitudinal direction of the roof material main body 1, and the cross-sectional shape in the horizontal direction of the connecting portion 3 is substantially corrugated (several ribs) such that the convex portions 3 a and the concave portions 3 b repeat alternately. Shape). The width L3 of the connecting portion 3 is preferably 100 to 200 mm from the side end of the roofing material body 1. The side edges in the lateral direction of the roofing material body 1 are bent to make the edges difficult to see from the outside in order to improve rust prevention and rigidity. Moreover, the metal roofing material A is left-right symmetric by providing the connection part 3 in both the side edge parts of the roofing material main body 1. FIG.

  The fitting part 4 is formed over substantially the entire length in the lateral direction of the roofing material body 1, and the vertical cross-sectional shape is formed in a substantially inverted U shape, and its thickness T is, for example, about 5 mm. Can do. The fitted portion 5 is formed over substantially the entire length in the lateral direction of the roof material body 1, and the vertical cross-sectional shape is substantially inverted V-shaped by connecting the upper piece 5 a and the lower piece 5 b at the eave side end. It is formed in a shape. Further, as shown in FIGS. 2B and 2C, the fitted portion 5 is formed so that the upper piece 5a and the lower piece 5b are close to and away from each other in the vertical direction so that the fitted portion 5 can be moved vertically. It is formed to be stretchable. The fixed piece 10 is formed over substantially the entire length of the roof material body 1 in the horizontal direction, and the cross-sectional shape in the vertical direction is formed in a substantially reverse letter shape, from the upper piece 5a of the fitted portion 5 toward the rear. Projecting.

  As described above, the metal roofing material A of the present invention is formed by combining bending portions of the fitting portion 4 as much as possible and combining portions that are easy to overlap. Also, the fitting part (front part) 4 is visible, so it is rounded, but the part to be fitted (back part) 5 has an inverted V shape to make it easy to process, and bending R processing Is lost.

  And the metal roof material A of this invention lays a plurality of the sheets on the roof base | substrate 6 of a field board etc. vertically and horizontally, and can thereby form a metal roof. In this case, the metal 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 metal roof materials A and A adjacent in the horizontal direction are connected by overlapping the side portions 2 and 2 up and down. Here, since the cross-sectional shape in the vertical direction of the metal roof material A 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, It is preferable to overlap 100 mm or more from the end, but the overlapping dimension can be changed according to the adjustment of the size of the storage of each part of the roof. In addition, although the upper limit of the dimension to overlap | superpose is not set in particular, since a useless part will increase in the metal roofing material 1, if it is too large, the dimension to superimpose shall be half or less of a horizontal dimension from the side edge of the roofing material main body 1. It is preferable that the thickness is 200 mm or less, and the overlapping portion can be the side portion 2 of the roof material body 1. Moreover, since the metal roofing material A is symmetrical, both the left and right sides of the metal roofing materials A and A adjacent in the horizontal direction can be overlaid as shown in FIGS. 4 (a) and 4 (b). The roof base 6 can be laid sequentially from either the left or right direction in the lateral direction. And by the substantially wave-shaped connection part 3, a space (gap) can be provided between the side parts 2 and 2 of the metal roofing materials A and A overlapped vertically, and rainwater drainage and capillary action can be prevented. Is. At this time, as shown in FIG.4 (c), the same effect can be acquired even if the convex parts 3a and 3a of upper and lower metal roofing materials A and A do not agree | coincide with concave parts 3b and 3b. The metal roof materials A and A adjacent in the vertical direction are connected by overlapping a part thereof vertically. In this case, the fitting portion 4 of the metal roof material A laid on the ridge side is fitted into the fitted portion 5 of the metal roof material A laid on the eave side.

  Here, the connection of the metal roof materials A and A in the horizontal direction and the vertical direction will be described in detail. First, as shown in FIG. 5 (a), the metal roofing material A is placed on the roof base 6 with the fitted portion 5 extended upward, and as shown in FIG. The fixing piece 11 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 fitted portion 5 is contracted up and down to reduce the vertical dimension (thickness). Next, another metal roof material A is placed side by side on the fixed metal roof material A. At this time, as described above, the adjacent metal roof materials A and A are connected by overlapping the side portions 2 and 2 vertically. Moreover, as shown in FIG.5 (c), the to-be-fitted part 5 of the metal roofing material A of the newly arrange | positioned is covered on the eaves side and upper side of the to-be-fitted part 5 of the fixed metal roofing material A. In addition, the fixed piece 10 of the metal roof material A to be newly arranged is placed on the upper side of the fixed piece 10 of the fixed metal roof material A. Next, as shown in FIG. 5 (d), the fixed piece 10 of the metal roofing material A in which the fixture 11 is newly arranged, the fixed piece 10 of the fixed metal roofing material A, and the roof base 6 are newly driven. The fixed piece 10 of the metal roofing material A arranged in is fixed. In this way, after laying a plurality of metal roofing materials A, A ... in a horizontal row, another plurality of metal roofing materials A, A ... are sequentially placed in a horizontal row on the ridge side of the laid metal roofing material A. Lay down. At this time, as shown in FIG. 5 (e), the fitting portion 4 of the metal roof material A on the ridge side is fitted to the fitting portions 5 and 5 overlapped on the eaves side, and thereafter, FIG. ), The fitting portion 4 of the metal roof material A on the other ridge side is replaced with the fitting portion 4 of the metal roof material A on the ridge side and the fitted portion 5 of the metal roof material A on the eave side. 5 and 5. Thus, the two fitting parts 4 and 4 and the two to-be-fitted parts 5 and 5 are finally fitted and overlapped, but the to-be-fitted part 5 is substantially inverted V-shaped. Since the overlapping surfaces are all diagonal (triangular), the fitting portion 4 can be smoothly fitted.

  Moreover, since the metal roofing material A of the present invention does not have a portion perpendicular to the surface of the roofing material body 1 in the fitting part 4 or the fitted part 5, as shown in FIG. It can be easily bent at a substantially right angle so that the side portion 2 protrudes upward. Therefore, the metal roofing material A is not cut in the storage structure of the boundary portion between the roof base 6 and the rising wall, and can be adjusted with the overlapping dimensions, and the generation of waste material at the construction site is minimized. Can do.

  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. 7A, a plurality of metal roof materials A, A are provided on the long surface 6a. ... is laid in the lateral direction and from the eaves side toward the ridge side, but the side 2 on the short surface 6b side of the metal roofing material A laid in the portion closest to the short surface 6b is folded to surface the short surface 6b Arrange along the line. Next, as shown in FIG. 7B, a plurality of metal roofing materials A, A... Are laid on the short surface 6b from the lateral direction and from the eaves side toward the ridge side. The side portion 2 on the long surface 6a side of the metal roof material A laid in the near part is bent and arranged along the surface of the metal roof material A laid on the long surface 6a. Thereafter, as shown in FIG. 7C and FIG. 8, the metal roofing material A can be constructed by attaching the cover material 13 having a substantially square cross section to the descending ridge 6 c and the ridge 6 d. And as shown in FIG.8 (b), like the case where it constructs in the boundary part of a roof base | substrate and a rising wall, it can accommodate and adjust a superimposition dimension, without cut | disconnecting the metal roofing material A. The generation of waste materials at the construction site can be minimized. Moreover, as shown in FIG.8 (c), when the metal roofing material A of this invention is constructed | assembled to the short surface 6b, it overlaps as it rolls up from the eave side to the ridge side (it shows with a dotted pattern). However, when the construction is performed on the long surface 6a, the dimension of the overlapped portion K (shown by dotted patterns) is constant and can be accommodated without being cut.

  Moreover, the metal roof material A of the present invention can be laid by a through-back plate method. As shown in FIG. 9, the through back plate 15 is formed long by providing protruding pieces 17 that protrude obliquely toward the surface side on both sides of the substrate 16. A waterproof packing 18 is provided on the surface of the protruding piece 17.

  The through-back plate method is performed as follows. First, as shown in FIG. 10 (a), a plurality of back plates 15 are arranged side by side in the lateral direction from the eave side of the roof base 6 to the building side and the descending building side. Here, in the conventional through back plate, although it was formed in the length dimension substantially the same as the vertical direction (eave ridge direction) of the metal roof material A, in the case of this invention, it covers the full length of the eave ridge direction of the roof base 6. The back plate 15 can be used as a single line, and a considerable working time can be reduced and an internal drainage structure similar to the conventional one can be formed. Next, as shown in FIG. 10 (b), two rows of metal roofing materials A and A are arranged in the first row on the eaves side. Next, as shown in FIG. 10 (c), another two rows of metal roofs are filled so as to fill the space between the two rows of metal roof materials A, A arranged at the first stage on the eaves side. Materials A and A are disposed. At this time, the side part 2 of the metal roof material A is overlapped with the side part 2 of another adjacent metal roof material A. Thereafter, similarly to the second and subsequent stages from the eaves side, as shown in FIG. 10 (d), after arranging two rows of metal roofing materials A, A, as shown in FIG. 10 (e), The other two rows of metal roof materials A and A are arranged so as to fill the space between the metal roof materials A and A. Thus, by laying a plurality of metal roof materials A, A... Sequentially from the eave side toward the ridge side, a roof as shown in FIG. In this case, by shifting the overlapping portion of the adjacent metal roof materials A and A in each stage, the joints can be prevented from overlapping in the eaves-ridge direction, and the appearance can be improved.

  And in the metal roofing material A of the present invention, the overlapping dimension (spreading foot) of the adjacent metal roofing materials A, A can be freely adjusted, so that the gap from the flat part, the descending ridge part, the wall rising part In order to adjust the dimensions, the roof material body 1 can be constructed without cutting. 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-length metal roofing material A, cutting is necessary. However, if the length is also adjusted at the factory, there is no need for cutting at the site, and there is no waste material. In addition, the metal roofing material A used in the loose part, the descending ridge part, and the wall raising part 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 metal roof material A of the present invention is simple and has a substantially flat shape, the metal roof material A can be constructed without being cut by bending the metal roof material A with the ridge line as a fulcrum. Moreover, since the shape of the metal roof material A of the present invention is simple, there is no need to process it after sheet metal work (unnecessary part cutting), and workability can be improved. In addition, even if the length of the metal roofing material A of the present invention is constant, it can be handled by placing an order in consideration of the roof area and the overlapping allowance without requiring on-site measurement, and the estimation and integration work is easy. Become. In addition, the metal roofing material A of the present invention is bilaterally symmetric and can be run from either the left or right side, and even when cut in half, it can be placed in a loose part or a descending ridge part so that the cut surface is on the surface. It can be stored without taking out, and can be efficiently squeezed without taking extra laps. In addition, the receiving member (cover material) of the descending ridge part and the ridge part has a simple shape, and the storage of the intersections and joints can be stacked as it is, and the length can be adjusted in the same way as the metal roofing material A. Can be reduced as much as possible.
