The non-combustible sheet 4 is integrated with the molded floor plate 3 with an adhesive or the like. Further, 1a is a tongue piece for enhancing waterproofness and preventing danger, and can also hold the end of the non-combustible sheet 4.

The fireproof panel A is formed on the back surface of the joint portion F of the fireproof panel B as shown in FIG. 1 to prevent infiltration of rainwater, flame, etc. from the space between the fireproof panels B to the building body α side, It functions as a guide or the like when fixing the panel B.

The non-combustible sheet 4 is a sheet made of inorganic fibers and is made of, for example, rock wool felt, ceramic wool, glass wool, etc., and is laid along the shape of the floor plate 3, as shown in FIG. After the joint portion F is formed, the joint portion is in close contact with the end of the fireproof panel B, which is effective for improving the fire resistance performance of the joint portion F.

The refractory panel B has, for example, a surface material 5 which has a shape as shown in FIG. 3 and is long, a core material 20 formed on the back surface of the surface material 5, and a back surface of the core material 20. It is formed in a sandwich structure from the back material 17 thus formed.

The surface material 5 is formed of a decorative surface 6 in a horizontal plane, a male fixing piece 7 formed at one end of the decorative surface 6, and a female fixing piece 8 formed at the other end. The male fixing piece 7 includes a groove 9 having a concave portion near the end of the decorative surface 6, a side wall 10 and a side wall 1 having an end of the decorative surface 6 bent downward.
The protruding piece 11 has a lower end protruding outward and a reinforcing piece 12 whose outer end is bent downward.

The groove 9 is a place where a fixing tool β for fixing the male fixing piece 7 side of the refractory panel B is provided, and has a surface parallel to the decorative surface 6 at the bottom, the depth of which is fixed. It is more than the height of the head of β. The cross-sectional shape of the groove portion 9 is preferably formed in a trapezoidal shape having a long bottom side for the purpose of attaching and locking the groove portion cover material E.
