However, in the conventional metal siding material, a synthetic resin foam is integrally interposed between a surface material and a sheet-like material such as kraft paper, and has a male and 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.

As described above, according to the joint structure of the present invention, a wide panel having fixing portions formed at both ends is used, so that 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. Since the insertion piece and the engagement piece are formed by projecting the distal end of the protruding piece outward, the insertion piece and the engagement piece become a waterproof surface, and rainwater and the like do not reach the skeleton side.
Horizontal stretching is also possible. Because of the structure in which the ends of the panels are connected to each other by the insertion pieces and the locking grooves, there is no gap between the panels, and the panels have excellent earthquake resistance, waterproofness, and airtightness. Because the metal surface material and back material do not contact even at the joints,
Excellent fire resistance, heat resistance and dew condensation resistance due to prevention of thermal bridges.
There are features and effects such as.
