[Problem to be Solved by the Invention] However, a gap γ is formed between the panels a1 and a2 by the head of the fixing tool β, and rainwater etc. blown up from the joint part b is prevented from forming the frame α by this large gap γ. There was a drawback that it could be transmitted to the side and corrode the main body α. Furthermore, since the fixture β is formed near the joint part b, rainwater etc. can directly reach the head of the fixture β,
Since the fixture β reaches the fixing hole drilled in the panel a1, there are drawbacks such as rusting of the fixture β and rainwater entering the frame α from the fixing hole. Also, this panel a
In order to install this, the joint width had to be adjusted one by one, and the construction required skill. In addition, this type of panel a has a synthetic resin foam integrally formed between the metal front and back materials, and since the synthetic resin foam that serves as the core material is flammable, it is compliant with JIS-A-1301, JIS −
Although they somehow passed the fireproof structure test of A-1302, there was no certainty that they passed the fireproof structure test of JIS-A-1304.

This is a part that functions as a fixing part for fixing the panel B to the frame body α by casting the fixture β. Further, the concave fixing groove 12 is formed to be larger than the height and width of the head of the fixing tool β, so that the fixing tool β does not protrude above the surface of the joint base 7, and the panel B is engaged with the fixing groove 12. When doing so, the upper surface 15 and the joint base 7, which will be described later,
This prevents the formation of a gap at the contact portion with the upper edge 10, thereby enhancing waterproofness. Furthermore, the reinforcing piece 13 is used to reinforce the male connecting part 8 side of the surface material 3, and to insert nails or the like into the fixing groove 12 when fixing panel B to the frame α, as shown in FIG. 1, the connecting part of panel B. When the fixing device β is driven, the reinforcing piece 13 is also fixed by the fixing device β, and when the insertion edge 9 is inserted into the fitting groove 17, the insertion edge 9 is prevented from being pressed and deformed by the lower surface 16. , which helps ensure secure fixation.

The female connecting portion 14 has an upper surface 15 in which the lower edge of the side wall 6 is bent inward, a lower surface 16 in which the tip of the upper surface 15 is bent outward, and the cross section formed by the upper surface 15 and the lower surface 16 is approximately U-shaped. It consists of a fitting groove 17 formed in the bottom surface 17 and a reinforcing piece 18 with the tip of the lower surface 16 bent inward, and this fitting groove 17 is engaged with the insertion edge 9 of the male connecting part 8. Panel B on frame α
This is the part that fixes the.

The back surface material 19 is formed of an inner piece 20 having one end edge of a long plate bent inward substantially parallel to the plate, and an outer piece 21 having the other end bent outward substantially parallel to the plate. A gutter-like part was formed from these.

This back material 19 covers the back surface of a core material 24 to be described later, making panel B a sandwich structure.
In addition to improving its own mechanical strength, it serves as a function of a noncombustible sheet, waterproof membrane, heat shielding material, soundproofing material, packing material, etc., and its material is a metal material of the same quality as the surface material 3. It is more than that. Its installation is
