This is the part that functions as a fixing part for fixing the panel A to the wall base α by driving fixing tools β such as nails into the wall. In addition, the concave fixing groove 13 is formed to be larger than the height and width of the nail head of the fixing tool β, so that the fixing tool β does not protrude above the surface of the joint basement 5, and the panel A is engaged. When doing so, no gap is formed between the upper surface 15 of the female connecting part 14, the joint base 5, and the upper edge 8, which will be described later, and a gap is formed by the fixing groove 13 to prevent capillary phenomenon. This helps strengthen waterproofness.

The female connecting portion 14 has an upper surface 15 in which the lower edge of the side wall 4 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. a fitting groove 17 formed in the bottom surface 17, a bottom surface 18 of the engagement piece having a tip end of the bottom surface 16 bent inward and having substantially the same length as the bottom surface 16;

This is the part that engages the engagement groove 11 and fixes the panel A to the wall base α. The steps 2b and 2c formed on the decorative surface 2a are for making the decorative joints step-like, thereby making the joints three-dimensional and clear, and improving the design.

As shown in FIG. 3, the back material 17 has vertical pieces 22 and 23 that project upward from both ends of a long plate, and the tips of the vertical pieces 22 and 23 are bent outward and inward. , horizontal pieces 24 and 25 having substantially the same length as the lower edge 10 of the engagement groove and the lower surface 18 of the engagement piece, an insertion portion 26 consisting of the vertical piece 22 and the horizontal piece 24, and the vertical piece 23 and the horizontal piece 25. The reinforcing pieces 28 and 29 are formed by bending the ends of the horizontal pieces 24 and 25 inward, and a gutter-like part 21a is formed from these pieces. This back material 21 covers the back surface of a core material 30 (to be described later) to make the panel A a sandwich structure, and improves the mechanical strength of the panel A itself. It serves as a packing material, etc., and is made of the same metal or synthetic resin material as the surface material 1. In addition, the insertion part 27 and the insertion part 26 are connected as shown in FIG. 4, and the insertion part 27 is fixed to the fixed insertion part 26, and both ends of the back material 21 are fixed to the wall base α. This makes the wall strong against external forces. Furthermore, the insertion part 26 and the insertion part 27 are designed to greatly improve fireproofing and airtightness.In particular, in the unlikely event of a fire, they prevent flames from penetrating to the back surface 21b, making them fireproof and fireproof. This is to make Panel A capable of passing the test. In addition, in the figure, in order to further improve fire resistance and fire resistance, the front material 1 and the back material 21 are formed so as not to come into contact with each other to prevent thermal bridging and dew condensation.

The core material 26 is mainly made of synthetic resin foam, which functions as a heat insulating material, a reinforcing material, a soundproofing material, a cushioning material, a fireproofing material, an adhesive material, etc., such as polyisocyanurate foam, phenol foam, Synthetic resin foams such as polyurea foam and polyimide foam, and flame retardants (borates, silicates, phosphates, etc.) in these synthetic resin foams.

Alternatively, it may be made of cement board, gypsum board, rock wool board, glass wool board, ALC, insulation board, wood chip board, glass wool, etc., and may be formed from a single material or a combination of multiple materials. In addition, in the figure, the core material 30 is formed by filling the gutter-like portions 1a and 21a of the surface material 1 and the back material 21, and by preventing the surface material 1 and the back material 21 from coming into contact with each other even at the connecting portion. Even if the material 1 is heated due to a fire or the like, the heat is not transmitted to the backing material 21, thereby improving fire resistance, heat insulation, and dew condensation resistance by preventing thermal bridges. Further, 31 is a male part, and 32 is a female part.

Further, 33 is a sealing material, and when the core material 30 is made of a material such as synthetic resin foam that is discharged as a raw material and foamed and hardened, liquid leakage occurs between the front and back materials 1 and 21. It is designed so that it does not occur.
