[0002] A truss made of steel bars as the upper chord, lower chord and web members connected by resistance spot welding is called a steel truss. The combined load-bearing plate formed by the steel truss and the bottom plate connected into an integral whole by resistance spot welding is called a steel truss floor deck. The earliest corrugated steel plates were mainly used for roof panels of factory roofs. Later, the corrugated steel plates used for floors were gradually classified as floor decking. When floor decking is used on floors, concrete needs to be poured on its surface.

[0003] After searching, the existing Chinese patent publication number is: CN219175609U, which provides an assembled non-disassembly floor decking. The patent uses cement fiber board, detachable parts and steel trusses. The detachable parts are composed of fixing parts and fasteners. The steel truss is composed of three main steel bars arranged in an axial direction. The main steel bars are connected to each other through web bars. The main steel bars are connected to the cement fiber board through fixing parts and fasteners. The fixing part is generally "concave" shaped, and an internal card interface in the shape of a barb is provided on one side of the fixing part, and an external card interface is provided at one end of the fixing part. The fastener is "U" shaped, and an internal card opening compatible with the internal card interface is provided on it.

[0004] Although the above patent can solve the problem of low work efficiency due to the need for welding work at the construction site, the above-mentioned prefabricated floor decking still has the following problems: the bottom plate and the steel truss are fixed by bolts, etc., and after the later pouring is completed, the bottom plate cannot be recycled, resulting in a waste of resources and a great waste of time. In addition, the structure of the joints of the prefabricated floor decking is simple, and it is easy to leak when the poured cement is not dry, resulting in a poor working environment.

[0005] In view of the above problems, an assembled prefabricated floor deck is proposed. Utility Model Content
