AI Technical Summary
In existing technologies, the strength of connectors in the reinforcement and renovation of old buildings is insufficient, which affects the reinforcement effect.
The external U-shaped vertical and horizontal steel frames are made by casting and are connected by connecting slots, grooves, connecting plates and blocks. They are then fixed to the beams and columns with bolts. The connection strength is enhanced by the cooperation of the forward and backward L-shaped brackets with the cantilever beams.
The reinforcement strength of the vertical and horizontal beams has been improved, ensuring the stability and practicality of the connection and enhancing the overall support effect of the reinforced structure.
