  When renovating existing roofs as they are, existing roofs (not shown) such as slate roofs, new tile roofs, tile roofs, tile roofs, metal side roofs, etc. are formed on these roof bases α. The existing roof structure is the roof base α. Of course, the exterior material A can be formed of an exterior material A such as a slate roof, a new tile roof, a tile roof, a tile rod roof, or a metal side roof.

  The metal exterior material B is formed by roll molding, press molding, extrusion molding, or the like of a metal plate (color steel plate, copper plate, aluminum plate, titanium plate, stainless steel plate, sandwich steel plate, clad steel plate, etc.), for example. . Of course, the surface material of the exterior material A may be formed of a ceramic material or a synthetic resin material (plastic) instead of the metal exterior material B.

  More specifically, the metal exterior material B has a long plate shape, and its one side edge in the width direction is bent in a substantially U shape on the lower side of the decorative surface 4, that is, on the back surface 5 side. A male connecting portion 9 having an insertion edge 7 is formed, and a substantially U-shaped hooking groove 8 is formed from the decorative surface 4, the stepped decorative surface 6, and the insertion edge 7.

  Further, the other end of the decorative surface 4 is provided with a fitting groove 10 which is bent upward from the decorative surface 4 and has a substantially U-shaped cross section to be fitted to the insertion edge 7 and a tip of the fitting groove 10. A female mold having a fitting edge 11 folded back in a letter shape, and a fixed piece 12 that is bent downward at the tip of the fitting edge 11 and bent outwardly in an L-shape substantially parallel to the decorative surface 4 The connecting portion 13 is formed. Further, the end of the decorative surface 4 is bent downward to form a waterproof piece 14 as shown in FIG.

  Furthermore, the insertion edge 7 is notched and the notch 15 is formed in the right-and-left end part of the metal exterior material B. FIG. When the notch 15 is formed as shown in FIGS. 2 (a), 2 (b) and 3 (a) to 3 (c) and connected as shown in FIGS. 1 (b) and 4 (b), It is formed so that the rainwater is not smoothly drained on the lower exterior material A through the matting plate D as shown in FIG.

  The backing material C functions as a waterproofing material, a heat insulating material, a sound absorbing material, a shock absorbing material, a fireproofing material, a dew condensation preventing material, etc., a non-woven fabric, a synthetic resin foamed sheet (for example, a crosslinked foamed polyethylene sheet), etc.), Use rock wool, tex (soft fiber board), rubber sheet, resin sheet, etc., or those impregnated with, impregnated with, mixed with, laminated (single layer or multiple layers), sandwich, etc. You can also

  In particular, the non-woven fabric is a non-woven fabric or the like in which various fibers are bonded with an adhesive or the like, unlike a conventional method in which warps and wefts are crossed to form a woven fabric from fibers. In this nonwoven fabric, fibers are crossed in parallel, or thin felts arranged randomly are bonded with an adhesive, or another thermoplastic fiber is mixed in the main fiber state, It is made by melting by heating and pressing and bonding them together. Of course, if the material itself is not waterproof, a resin material is coated, or a waterproof function is added to one or both sides with a water repellent, a waterproof coating agent, or the like.

  The siding plate D is as shown in FIGS. 4A and 4B, and includes a groove 16, an upper piece 17, and a side piece 18. The material is made of a metal plate material, a plastic material, or the like, and is, for example, a short material formed by press-molding a metal plate material. The laying board D is constructed as shown in FIGS. 1B and 4B to prevent rainwater from entering from the joints. In addition, as shown in FIG.1 (b) and FIG.4 (b), the upper piece 17 and the side piece 18 of the lining board D are contact | abutted and formed so that it may bite into the backing material C of the exterior material A, and it is waterproof. To demonstrate.
