Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering equipment, in particular to a steel bar truss floor deck. Background Art

[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.

[0003] The utility model patent with announcement number CN211007249U discloses a steel truss floor deck, in which the truss does not need to be welded to fix it when connected to the floor deck body. However, during the use of the truss structure of the application, due to the bumps during transportation and the force majeure caused by the accidental collision with the truss, the connection structure of the truss as a whole will be deformed to a certain extent, thereby affecting the overall force direction and causing the overall load-bearing capacity to be unstable. For this reason, we propose a steel truss floor deck. Utility Model Content

[0010] Specifically, each welding point of the bottom support rod, the first support rod and the second support rod is welded to the lower chord rod.

[0011] By adopting the above technical solution, the triangular structural strength of the truss body is enhanced by welding the bottom support rod, the first support rod, the second support rod and the lower chord rod, thereby improving the overall strength of the truss.

[0012] Specifically, the bottom end of the bottom support rod is fixedly connected to the top end of the bottom plate.

[0013] By adopting the above technical solution, a stable supporting point is obtained by connecting and fixing the bottom support rod to the bottom plate.
