However, the conventional metal siding material has a synthetic resin foam integrally interposed between a surface material and a sheet-like material such as kraft paper, and has a male-female connection structure and a structure in which only one end is fixed. The width of the decorative surface is about 400mm,
When the thickness is about 25 mm or more, there are disadvantages that the siding material is easily detached, the decorative surface becomes mountain-shaped, and it is difficult to insert the male and female connecting portions. Further, the sandwich panel has a disadvantage in that it lacks aesthetics due to its structure being beaten in the brain via bolts, and must be constructed with a crane or the like. Of course, ALC siding and ceramic siding materials were heavy, had limited decorative surface and thickness, were difficult to construct, and had weaknesses in freeze-thaw. Further,
Covers the joint by attaching the cap with the mounting bracket,
Although the fixture was prevented from being exposed to the exterior, the mounting of the cap required a mounting bracket, which was poor in workability and poor in heat insulation and waterproofness. In addition, there is a risk that the joint cover may be detached if the panel is not properly installed, which also has a disadvantage of poor heat insulation and waterproofness.

According to the joint structure of the wall according to the present invention as described above,
Since a wide panel with a hat-shaped cross section is used, both sides of the decorative surface can be firmly fixed to the frame. The nail head does not appear on the decorative surface of the panel and can be formed into a beautiful appearance. Since the panel is fixed on both sides, there is an advantage that the decorative surface does not have a mountain shape. Since an attachment is not required to attach the joint cover to the joint, the workability can be improved. In the case where the joint of the joint cover is one, even if the joint between the panels becomes wider or narrower, the joint cover can be easily attached regardless of the dimensions. Horizontal stretching is also possible.
Waterproof, airtight, shockproof, thermal insulation, fireproof, soundproof,
Panel with improved workability. There are features and effects such as.
