In this embodiment, since there is no need to weld angle steel or other steel members for placing the steel bar truss floor support plate 20, the construction is more convenient, quick and efficient, and the construction period can be shortened.
The following is a specific example:
if the width of the concrete frame beam 10 is b=400 mm and the thickness of the reinforcement cover c=25 mm, the width of the beam stirrup assembly 11 is 400mm-25×2=350 mm.
