[Problems to be Solved by the Invention]

However, the conventional metal siding material has a structure in which a synthetic resin foam is integrally interposed between a surface material and a sheet-shaped material such as kraft paper, and has a male-female connection structure, and a structure in which only one end is fixed, If the makeup width is about 400 mm and the thickness is 25 mm or more, there are drawbacks that the siding material is likely to come off, the makeup surface has a mountain shape, and it is difficult to insert and insert the male and female connection parts. In addition, the sandwich panel has a structure that is struck by the brain through bolts, which is unattractive and has the disadvantage of having to be constructed with a crane or the like. Of course, ALC and ceramic siding materials are heavy, have a limited decorative surface and thickness, are difficult to apply, and have the drawback of being vulnerable to freezing.

[Means for solving the problem]

In order to eliminate such drawbacks, the present invention forms a rectangular or rectangular decorative surface and side walls protruding downward at four side edges of the decorative surface, and projects the lower end of each side wall outward. And a protruding piece formed to form a cutout portion at two corner portions diagonally located out of the four corner portions of the protruding piece to divide into a polymerization protruding piece and a supporting protruding piece, In addition, a surface material having a height difference from the decorative surface of the protruding piece for polymerization and the supporting protruding piece, and a box-shaped recess surrounded by the decorative surface and the side wall of this surface material are filled and By excluding the back surface of the piece, by comprising a core material that swells and fills downward with an equal thickness in a region including the back surface of the supporting projection piece, and a back surface material that covers at least the back surface of the core material,
We propose a sandwich panel with improved heat insulation, waterproofness, soundproofing, earthquake resistance, wind pressure resistance, and aesthetics.
