AI Technical Summary

⚠Technical Problem

In existing precast shear wall structures, the soft cable connectors are difficult to tension and adjust during on-site installation, and are prone to loosening, which affects the initial stiffness and deformation coordination of the horizontal joints. Furthermore, the lack of simple and effective tensioning devices leads to low construction efficiency.

⚗Method used

The steel strand tension is adjusted by using a slot connection assembly, which connects two slot pieces to the pull rod. Combined with the tight sleeve and countersunk hole design, the tension of the steel strand is adjusted. The mechanical connection of the pull rod avoids complicated grouting or welding operations, forming a closed-loop fixation.

🎯Benefits of technology

It effectively solved the problem of steel strand slack, ensured the initial stiffness of the horizontal joint, simplified the construction process, achieved a connection effect that combines rigidity and flexibility, and ensured the ability to transfer shear force and coordinate deformation.

Abstract

The application discloses a prefabricated shear wall cable slot connecting structure and a construction method thereof, and belongs to the technical field of building construction. The structure comprises a first prefabricated shear wall and a second prefabricated shear wall, anchor steel bars are pre-buried in the walls, and a steel cable is arranged around the walls, the two ends of the steel cable extending to the adjacent sides of the walls. A slot connecting assembly is arranged between the opposite steel cables of the two walls, the assembly comprising two symmetrical slot pieces, a counterbore being formed on one side of each slot piece, and a rope passing hole being formed on the other side of each slot piece and communicating with the counterbore, the two ends of the steel cable passing through the rope passing holes and being fixed by a tight sleeve pipe, and the two slot pieces being connected by a pair of pull rods. During construction, the prefabricated walls are hoisted into position, the steel cable is connected with the slot pieces and is tensioned, and the post-poured belt and the corrugated pipe concrete are poured after formwork is erected. The steel cable is tensioned and adjusted on site by the slot connecting assembly, connection slack is avoided, the initial rigidity of the joint is ensured, the joint ductility is good, and force can be reliably transmitted by combining flexible anchoring with rigid connection, and the construction is simple and efficient.
