Steel plate of the outer skin is plated with zinc, magnesium, aluminum alloy, so when applied to buildings in coastal areas, fluorine coating is required on the outer circumference to prevent salt damage, thereby increasing the cost or damaging the coating film. Even if it is difficult to compensate for this problem.

Literature 3 relates to a sandwich panel for construction, wherein a metal plate is disposed on both sides of a non-combustible material, and a non-combustible material and a metal plate are integrally formed with a non-flammable adhesive to reduce weight, thereby providing convenience for transport to an operator.

As shown in Fig. 2, the sandwich panel of Document 3 includes a bead method, one heat insulating plate, a bead method, two heat insulating plates, an extruded heat insulating plate, a hard urethane, a phenol foam, glass wool, mineral wool, a vacuum insulation material, and heat. Only one or more of reflective insulation, water-based flexible foam insulation, or bead-based insulation is used to improve the insulation, and the type of steel used is not listed, so even if it is applied to buildings in coastal areas, the damage caused by salt damage Hard to prevent.

Document 4 relates to a sandwich panel that is easy to assemble and dismantle, wherein the first joint part and the second joint part are formed at both ends of the side where the outward metal plate is coupled to be screwed together.

The sandwich panel of Document 4 uses a method in which the first joint part of one of two panels disposed adjacent to each other is screwed into the second joint part of the other panel. As shown in FIG. 3, an empty space is formed between the panel and the panel. Is formed there is a problem that the rain water is introduced by the capillary phenomenon is leaking.
