Abstract

[0002] A truss constructed with steel bars as top and bottom chords and web members, connected by resistance spot welding, is called a steel truss. The combined load-bearing slab formed by resistance spot welding the steel truss and the base plate is called a steel truss floor deck. Concrete pouring is the core step in cast-in-place beam construction. Construction workers place rebar and other fixing materials inside the formwork before pouring concrete directly into it. Furthermore, appropriate vibration is applied depending on the pouring height.
[0003] The existing construction technology of cast-in-place concrete slabs and beams on floors still has some defects. Most of them use formwork for laying and reinforcement, and finally pouring. This requires a lot of manpower to remove the formwork, which reduces work efficiency. For this reason, we propose a thin flat steel truss floor deck and cast-in-place concrete beam construction node support structure. Utility Model Content
