It is necessary to reinforce the connection between the beam and the column to improve the safety and stability of the steel structure. The existing reinforcement method mostly adopts welding reinforcing steel plates at the bottom of the beam and the side of the column to reinforce the connection between the beam and the column. The reinforcement method of the reinforced steel plate can only passively increase the supporting force, and cannot apply prestress to the bottom of the beam to support it. At the same time, welding operations are carried out at high altitudes, which are difficult and dangerous, and it is inconvenient to fix the reinforcing steel plates. Utility Model Content
