Detailed Description
As shown in fig. 1-6, the utility model provides an assembled composite floor structure, mainly be the assembled structure that comprises profiled sheet 1, apron 2, concrete, fire proof board 5, connecting piece 6. The utility model discloses an in the concrete embodiment, wave form profiled sheet is chooseed for use to the profiled sheet, and fixed connection's such as accessible spot welding or bolted connection mode makes a plurality of profiled sheets connect gradually the back tiling become a whole between a plurality of profiled sheets. The top of profiled steel sheet is provided with the apron, and preferably, the apron chooses thin-walled steel, through with thin-walled steel through the mode of fixed connection such as welding or bolted connection, lays in the profiled steel sheet top, on the one hand, can satisfy combination floor surface flatness and the requirement of reinforcing combination floor intensity and rigidity, and on the other hand has realized the processing of sealing of a plurality of profiled steel sheets. A cavity is formed between the sealed profiled steel sheet and the thin-wall section steel, concrete is filled in the cavity, the advantages of light weight and strong anti-seismic performance of the profiled steel sheet and the advantage of strong compressive capacity of the concrete are fully exerted, and the defects of low shearing resistance and easy deformation of the profiled steel sheet can be effectively overcome by filling the concrete in the cavity of the profiled steel sheet. It should be noted that the concrete includes standard concrete 3 and lightweight concrete 4, wherein, in order to increase the shear resistance of the end of the composite floor slab, a cavity in the range of the flexural shear section of the composite floor slab is filled with standard concrete of C30; in order to effectively reduce the dead weight of the composite floor slab, lightweight concrete is filled in the cavity in the range of the pure bending section of the composite floor slab.
In addition, the bottom of the profiled steel sheet is also provided with a fireproof plate which is fixedly connected through a connecting piece. In order to effectively improve the anti-stripping capability of the profiled steel sheet and the fireproof plate and further improve the integrity of the composite floor slab, the connecting piece adopts a shear key, and in a specific embodiment, the shear key can adopt any one of stainless steel self-plugging rivets, shooting nails, bolts, metal steel nails and self-tapping screws according to the design requirement; the fireproof coiled material can be a gel plate, a calcium silicate plate or other fireproof plates and is specifically arranged according to the fireproof requirement.
