PURPOSE:To permit direct setting of interiors of floor on the upside of a slab by a method in which a formwork is assembled along the periphery of the slab, many steel pipes for forming a hollow are set horizontally in parallel, and concrete is placed in to the space surrounded by the formwork. CONSTITUTION:A trench 11 is excavated along the peripheral footing portion of a slab and cobble stones 12 are laid in the trench 11 and on the building land surrounded by the trench 11. A moisture-proof sheet 16 is then laid over the whole surface of the cobble stones 12 on the building land. A formwork 13 is assembled along the periphery of the slab, reinforcing bars 14 are set, many steel tubes 15 for forming a hollow are horizontally set in parallel, and concrete is placed into the space surrounded by the formwork 13. The upside of the slab is leveled to enable the floor interior, e.g., carpet, mat, etc., to be directly set on the upside of the slab. |
