Of course, when the existing wall is peeled off as the base α, or when the existing wall is repaired as the base α as it is, the existing wall structure in which the existing wall (not shown) is formed on the base α is the base α. It will be. Of course, the base α on which the waterproof sheet 3 is not formed may be used.

  The metal outer wall 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, instead of the metal outer wall material B, the surface material of the outer wall material A may be formed of a ceramic material, a synthetic resin material (plastic), or the like.

To further illustrate, metal siding B is a long plate shape, as shown in FIG. 1 (a) ~ (c) , and Ryakutaira planar decorative surface 4, a back surface 5, of the decorative surface 4 tip , A stepped decorative surface 6, a stepped decorative surface 6 and an upper surface 7 projecting inward along the decorative surface 4, an innermost piece 8 projecting the tip of the upper surface 7 downward, and an innermost piece 8. A substantially U-shaped engagement groove 10 is formed from the insertion piece 9 whose tip is protruded under water, the upper surface 7, the innermost piece 8, and the insertion piece 9, and the upper surface 7 and the engagement groove 10 An insertion gap 11 is formed, and the decorative surface 4 has a protruding piece 4a further protruding from the water-side tip of the decorative surface 4, as shown in FIGS. 1 (b), 1 (c), 2 (a) and 2 (b). In this way, the protrusion 4a on the underwater side of the decorative surface 4 is partially bent with respect to the longitudinal direction on the upper side in the drawing to form the concavo-convex portion 4b to form the male connecting portion 12.

Further, as shown in FIGS. 1A to 1C, a fixed piece in which the upper end portion of the decorative surface 4 protrudes further to the upper water side and the tip hangs down to the lower water side at the upper surface portion of the decorative surface 4. 15, a first waterproof piece 13 with the lower end of the fixed piece 15 bent upward, an upper surface 14 with the tip of the first waterproof piece 13 protruding upward, a top surface 14, and a fixed surface 15.
