STEEL/CONCRETE COMPOSITE FLOOR SLAB USING STEEL BEAM OF HAT-SHAPED CROSS SECTION, AND ITS CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a steel/concrete composite floor slab and its construction method of high concrete filling performance and working efficiency without slidingly fitting hat-shaped steel beams to each other. SOLUTION: In the construction method of the steel/concrete composite floor slab, a plurality of hat-shaped steel beams 1 are arranged in parallel on the same level over spaced support girders 10, and the hat-shaped steel beams 1 with arm parts 4 placed at the respective hat-shaped steel beams 1 and arranged in parallel are continuously arranged in the longitudinal direction of the support girders 10. Concrete is placed and solidified in a recessed part 11 between webs 3 of the adjacent hat-shaped steel beams 1 to continuously integrate the hat-shaped steel beams 1 arranged in parallel. After continuously integrating the hat-shaped steel beams 1, the upper faces are provided with surface pavement 20 such as concrete or asphalt pavement to form a multilayered structure.
