Combined floor slab

The utility model relates to a combined floor slab consisting of upper iron steel bars, lower steel bars, wave-shaped steel bars and a profiled steel sheet, wherein the upper iron steel bars and the lower iron steel bars are arranged in a staggered manner, two sides of each upper iron steel bar are provided with lower iron steel bars, the wave-shaped steel bars are connected between the upper iron steel bars and the lower iron steel bars, and the lower iron steel bars are connected with clamping pieces and the profiled steel sheet. Compared with the prior art, the combined floor slam provided by the utility model has the advantages that the construction temporary support is omitted, so that the combined floor slab construction becomes more convenient, the construction schedule is accelerated effectively, the construction period is shorted, and the construction cost is lowered; through built-in space trusses, the lower iron steel bars and the profiled steel sheet work together so that the stress performance of the combined floor slab can be improved effectively; in design, the diameter of the lower iron steel bars of the combined floor slab can be reduced, and therefore steel can be saved and the combined floor slab becomes more economical and reasonable.
