PROBLEM TO BE SOLVED: To provide a composite deck floor structure of a simple structure that enhances construction work efficiency, realizing an open living space by securing a high ceiling height while keeping a floor height low, by eliminating a need to install a binder.SOLUTION: In a building comprising a reinforced concrete column and a steel beam 12, a composite deck floor structure includes a lower flange part 21 connected to an upper flange 12a of the steel beam 12, the lower flange part being of a groove shape formed by bending into a groove-shaped cross-section, with a groove opening facing upward. Also included are a plurality of groove-shaped members 2 arranged with a lengthwise direction X2 thereof facing a direction orthogonal to a beam axial direction X1 of the steel beam 12, a reinforcing bar 3 placed on top of the groove-shaped members 2 arranged on the steel beam 12, and concrete 4 cast to have the reinforcing bar 3 embedded. Web parts 22 that form the groove shape of the adjacent groove-shaped members 2 are connected using a high-strength bolt.SELECTED DRAWING: Figure 1 |
