AI Technical Summary
The lack of effective auxiliary reinforcement structures at the connection nodes of the steel T-beams of bridges leads to insufficient safety and load-bearing strength at the connection points, making them prone to cracking or movement due to prolonged external forces.
The structure adopts a vertical connection of longitudinal and transverse steel beams. Primary and secondary reinforcement components are set at the connection. Through the combination of main reinforcement components, support arms and connectors, a ring-shaped connection is formed and fixed with connecting bolts to distribute pressure and improve the stress level.
It effectively improves the stress strength and safety of bridge connections, avoids cracking and movement caused by vertical external forces, and enhances the overall reinforcement effect of the bridge.
