<p>PROBLEM TO BE SOLVED: To provide a construction method of a concrete hollow slab in which an embedding body can be fixed in a slab reliably and firmly, the tilt and lateral movement of the embedding body may not occur even by concrete pressure or buoyancy of the embedding body in the concrete placement, a covering thickness with the concrete of the embedding body is secured and a sufficient proof stress can be obtained, workability, stability and high quality are superior, and repair work is unnecessary while having superior workability and labor saving properties.SOLUTION: A construction method of a concrete hollow slab includes: a bottom rebar arrangement step of arranging a bottom rebar in a lattice pattern; a bottom fixing rebar arrangement step of arranging a bottom fixing rebar to support a bottom side of the embedding body between adjacent bottom rebars; a top fixing rebar temporal placement step of temporarily placing a top fixing rebar for securing a top side of the embedding body on the bottom rebar or the bottom fixing rebar; a top rebar arrangement step of arranging a top rebar in the lattice pattern; an embedding body installation step of installing the embedding body on the bottom fixing rebar in a space partitioned by the bottom rebar and the top rebar; and a top fixing rebar engagement step of engaging the top fixing rebar between the embedding body and the top rebar.</p> |
