CONCRETE SLAB STRUCTURAL MEMBER AND CONSTRUCTION METHOD FOR POURING SAME

摘要

A concrete slab structural member comprises a frame of cold bend thin wall steel profiles and concrete enclosing the same, in which the main surfaces of two longitudinal cold bend thin wall steel profiles (51, 52, 91, 92) included in each longitudinal cold bend thin wall steel profile keel are parallel to the main surface of the concrete slab, the two longitudinal cold bend thin wall steel profiles (51, 52, 91, 92) are spaced apart and opposite each other along a direction perpendicular to the main surface of the concrete slab, so that a space (200) for the concrete to flow through when it is poured is left between the two longitudinal cold bend thin wall steel profiles. Also provided is a construction method for building a concrete slab structural member. The structural member has avoided or reduced as much as possible the problem of the flowing of concrete being hindered when it is poured, due to the placement of the cold bend thin wall steel profiles perpendicular to the concrete slab, which exists in the concrete structural member with cold bend thin wall steel profiles in the prior art, and the problem of cold bridges that is created by the perpendicularly placed cold bend thin wall steel profiles in the concrete formed after pouring the same.
