PURPOSE:To form a wide variety of floor finishing surface easily by interposing a sheet material, whose steel plate covering a floor wiring pit is dividually arranged and secured, and which is provided with a number of soft convexed bodies or a suction construction on its upper surface, between a floor having a wiring pit and a finishing material composing the floor finishing surface. CONSTITUTION:Plurally divided rigid plates 12 are arranged and fixed by crossing them horizontally and vertically on the back of a flexible non-woven fabric sheet 10 which has a number of soft convexed bodies 11 of polyvinyl chloride attached to its top surface. A height adjusting plate 13 of approximately the same thickness as the rigid plate 12 attached to the back of the non-woven fabric sheet 10 on spots other than where rigid plates 12 are arranged and secured. A sheet material 1 is then made by adhering a polyethylene foam sheet 14 on the back of the rigid plate 12 and the height adjusting plate 13. When accomplishing construction, firstly, wiring pits 30 are arranged on a floor wall 3 so as to make them join together. The wiring pits 30 are then covered with the rigid plate 12 of the sheet material 1, the sheet material 1 laid on the floor wall 3 and a finishing material 2 laid thereon. |
