Honeycomb profiled steel sheet-concrete precast slab

A honeycomb profiled steel sheet-concrete precast slab is suitable for the construction field, and comprises a honeycomb profiled steel sheet and a concrete floor, wherein the honeycomb profiled steel sheet is a corrugated steel sheet formed by bending or press-rolling a thin steel sheet with regular honeycomb holes; the lower flange of the honeycomb profiled steel sheet and concrete are poured into a whole, so that the precast slab (a precast unit) is obtained finally; the lower flange of the honeycomb profiled steel sheet extends out for a certain section, so that splicing of precast units is fabricated. Due to the holes formed in the profiled steel sheet, the bonding effect between the profiled steel sheet and the concrete floor can be further enhanced, and transverse reinforcement or pipelines can penetrate through the holes conveniently.
