[0002] In the basement or ordinary floor of a house building, frame beams with a cross-sectional size of 300mm×700mm or more are usually set between the load-bearing columns. The common casting method of frame beams is to install transverse steel pipes on the vertical poles of the floor formwork support with steel pipe fasteners, and then place longitudinal wooden strips or square steel pipes and other supporting parts on the transverse steel pipes to form a supporting surface. The bottom of the beam is often deflected due to insufficient anti-slip force of the steel pipe fasteners or insufficient rigidity of the horizontal horizontal steel pipes, and the deflection of the bottom of the beam affects the construction quality. When the cross-section of the frame beam is large, it is also necessary to add vertical poles at the bottom of the beam, and set a top support to support the steel pipe cross beam, which increases the material consumption and the workload of manual installation and removal. At the same time, the supporting capacity of the vertical poles near the beam side is not fully utilized. Summary of the invention
