Abstract

PROBLEM TO BE SOLVED: To provide a floor structural body causing no slip and no deviation between a floor decorative material and a substrate and excellent in walking feeling by forming a floor substrate section with folding plate-like members having valley sections and ridge sections, and affixing cushioning materials to the apex faces of the ridge sections of the folding plate-like members. SOLUTION: After the rear beam of a frame B is fitted to a building skeleton, folding plate-like members 20 are fixed on floor joists so that water stop materials are inserted between the connecting end sections of the folding plate-like members 20 and the end sections are overlapped with each other. Cushioning materials 10 such as rubber sheets are affixed to the apex faces 221 of ridge sections 22, and a floor decorative material 30 is laid on the cushioning materials 10. The execution work is simple, and most of the water flowing down from the floor decorative material 30 is drained in a short time from the valley sections of the folding plate-like members 20 even at a localized torrential downpour in use. Since the cushioning materials 10 are affixed to the apex faces 221 of the ridge sections 22 of the folding plate-like members 20, the walking sound caused by the abutting of the floor decorative material 30 with a floor substrate section at the time of walking can be prevented, and the floor decorative material 30 is prevented from slipping on a floor substrate face.
