AI Technical Summary
In the use of prefabricated connectors in existing steel structure buildings, the connecting piles only fix one side of the crossbeam, resulting in a large torque on the crossbeam on the connecting piles, the tie rod bearing a large tensile force, and the connecting bolts being prone to stress concentration, leading to damage.
By setting multiple sets of screw holes at the front and rear of the connecting pile, combined with the fixing plate and the limiting frame, the radial and axial limiting and fixing of the crossbeam is achieved, thereby enhancing the installation stability of the crossbeam on the connecting pile.
This effectively avoids the fixing bolts from bearing shear force, extends the service life of the bolts, improves the bearing capacity of the connecting piles and the installation stability of the crossbeams, and enhances the reliability of the connection.
