Composite floor structure

Abstract

The invention discloses a composite floor structure. The composite floor structure comprises a truss girder, a profiled steel sheet and an upper layer plate, wherein a sinking groove used for containing the profiled steel sheet is formed in the top of the truss girder, fixing devices used for fixing the profiled steel sheet are installed at the two ends of the sinking groove, each fixing device comprises a plurality of inserting plates, a plurality of inserting grooves are formed in one end of the sinking groove, the inserting plates are inserted into the inserting grooves in a one-to-one correspondence mode, the inserting plates are fixedly connected to the bottom of the profiled steel sheet, limiting grooves are formed in the inserting plates, limiting plates are slidably connected into the bottom walls of one ends of the sinking grooves, the limiting plates can be inserted into the limiting grooves, inclined planes are arranged on the opposite inner sides of the limiting plates and the inserting plates respectively, and the two inclined planes are matched with each other; an elastic assembly used for driving the limiting plates to move in the direction close to the inserting grooves is installed in the bottom wall of one end of the sinking groove, and a driving mechanism used for driving the multiple limiting plates to move in the direction away from the limiting grooves is installed at one end of the sinking groove. According to the composite floor structure, the profiled steel sheet is convenient to disassemble and assemble.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a composite floor structure. Background technique [0002] At present, composite floor slabs can also be called floor slabs, load-bearing slabs, floor slabs, floor slabs and steel slabs. [0003] For the prior art, please refer to the Chinese utility model patent whose authorized notification number is CN207794401U, which discloses a composite floor slab, which includes a truss beam, a profiled steel plate fixed on the truss beam, and an upper plate fixed on the profiled steel plate, There are at least two hoisting rods installed on the truss beam, the hoisting rods are located under the profiled steel plate, and at least three hoisting holes are opened on the upper layer, the hoisting holes pass through the upper layer and the profiled steel plate, and the hoisting holes are located at the bottom of the hoisting rod directly above, at least one hoisting hole is ...

AI Technical Summary

Problems solved by technology

[0004] However, the existing profiled steel plates and truss beams are often connected by welding, which may make it inconvenient to disassemble and assemble the profiled steel plates
