[0002] During the construction process of the increasingly popular disk-type scaffolding formwork support system, the formwork support system is a difficult and key control object affecting quality and safety during the construction process. In the ordinary formwork support system scheme, the cross bar at the bottom of the beam is usually not connected to the side frames, or a double-support beam form is adopted. Since the cross bar at the bottom of the beam does not share or is not allowed to share with the frame, during the installation construction process at the bottom of the beam, the position at the bottom of the beam is difficult to fix and is prone to shift to both sides; while the double-support beam is limited to the erection of the frame, and often on complex construction surfaces, the double-support beam cannot be applied; in view of the above-mentioned technical disadvantages of the bottom beam frame erection and formwork reinforcement, this patent combines on-site construction and construction plans to reduce the mixed use of steel pipes at the current construction site and the easy deviation of the bottom beam formwork reinforcement.
