[0002] Under the premise of advocating green construction and prefabricated construction, steel truss floor decking composite floor is widely used in industrial and civil buildings (structures). Steel truss floor decking has the advantages of mechanized production and prefabricated construction, which can significantly reduce the amount of on-site steel bar binding work. Its steel bar spacing and concrete cover are uniform, which improves the construction quality of the floor slab and has a fast construction progress, meeting the national green energy-saving and environmental protection requirements.

[0003] During the construction phase, the steel truss floor slab must bear the deadweight of wet concrete and the construction load. During the use phase, the steel truss and the concrete as a whole bear the use load together. Therefore, the steel truss floor slab should be designed in two stages: construction and use. According to the different restraint forms, the steel truss floor slab composite floor is divided into simply supported and continuous slab. During the construction phase, the elastic stage analysis method is used to calculate the load effects of the steel truss and the bottom formwork respectively.

[0004] Most of the existing related devices directly use bolts and welding to lock the bottom support of the steel truss floor deck. This method is very difficult to disassemble later, and it is easy to continue to expand the degree of inclination after the inclination occurs, and even cause lodging.
