PURPOSE:To prevent a siding material from coming off by making material of the surface and the rear of metal plates, laying insulating materials as a unit between the materials of two sides and providing projecting pieces interlocking with a skeleton to both sides of a facing plane in case of execution. CONSTITUTION:Insulating materials 7 with a hat-like cross section are sticked on the rear of a metallic surface material 1 with a hat-like cross section and a longer body, and the rear of the insulating materials 78 is coated with a metallic rear plane material 8 to form into a sandwich construction. At that time, an inclined and bent side wall 3, projecting pieces extended outward, an inclined and bent joint cover fittings guide section 5 and side pieces 6 are respectively formed downward of both side edges of a rectangular facing plane 2 of the surface material 1. |
