AI Technical Summary

Technical Problem

In modular buildings, when precast beams are connected to precast shear walls, it is difficult to anchor the reinforcing bars of the beams into the precast shear walls, especially when there are dense reinforcing bars at the ends of the precast shear walls. The reinforcing bars of the beams and the longitudinal bars of the shear walls interfere with each other, making anchoring difficult.

Method used

Auxiliary connectors are installed at the intersection of the load-bearing beam and the longitudinal reinforcement of the shear wall. The auxiliary connectors have through holes in the middle, through which the reinforcing bars with greater stress are allowed to pass completely, while the reinforcing bars with less stress are cut off and connected to both sides of the auxiliary connectors. The steel components have cuts on the sides to avoid interference, and are fixed by welding or threaded connection.

Benefits of technology

This solution resolved the interference issue between the load-bearing beam members and the longitudinal reinforcement of the shear wall, ensuring that the load-bearing beam members could be smoothly anchored in, enhancing the structural integrity and seismic performance of the modular building, and improving the connection reliability and stiffness of the nodes.

Abstract

The application discloses a connecting structure for a modular building with dense steel bars at a beam-wall joint, wherein the modular building is provided with a prefabricated beam and a prefabricated shear wall, a vertical steel piece is embedded in the prefabricated shear wall, a beam stress piece of the prefabricated beam is anchored into the prefabricated shear wall, an auxiliary connecting piece is arranged at a position where the beam stress piece intersects with longitudinal reinforcement of the shear wall, a through hole is arranged in the middle of the auxiliary connecting piece, and steel bar connecting structures are arranged on opposite sides of the auxiliary connecting piece; the beam stress piece is compared with the longitudinal reinforcement of the shear wall, wherein a steel bar with relatively large stress is kept intact and passes through the through hole of the auxiliary connecting piece, and a steel bar with relatively small stress is cut off and fixedly connected with the steel bar connecting structures on the opposite sides of the auxiliary connecting piece; a side surface of the steel piece is provided with a notch corresponding to a position of the beam stress piece, a part of the beam stress piece anchored into the prefabricated shear wall passes through the notch, and the beam stress piece and the steel piece are welded. The application can still anchor the beam stress piece under the condition that the steel bars are dense at the end of the prefabricated shear wall.
