AI Technical Summary

Technical Problem

The existing prestressed concrete truss reuse process suffers from problems such as uneven disassembly leading to uneven stress release, unstable storage causing deformation or cracks, difficulty in verifying the structural performance after reinforcement, and low positioning accuracy during reinstallation. These problems result in low reuse qualification rate, high cost, serious waste of resources, and safety hazards.

Method used

The construction method employs tiered unloading, adaptive buffer storage, targeted reinforcement, tiered loading, and intelligent positioning installation, including a prestressed precision unloading system, an adaptive buffer platform, carbon fiber reinforcement, tiered loading tests, and an intelligent positioning installation system, to ensure stable disassembly, stable storage, effective reinforcement, and comprehensive performance testing.

Benefits of technology

It significantly improved the truss reuse qualification rate to over 98%, increased construction efficiency by 40%, reduced resource waste and project costs, and ensured the safety and stability of the structure.

Abstract

The application discloses a construction method for overall recycling of roof prestressed concrete truss, which comprises the following steps: S1, truss dismounting: the truss is subjected to graded unloading, and the stress increment of each grade of unloading is not more than 10% of the design prestress of the truss; S2, layered buffer storage: single-truss trusses are subjected to layered buffer storage by using self-adaptive buffer pedestals; S3, reinforcement of the trusses, double-truss splicing and re-reinforcement, and formation of combined roof trusses; S4, static load test of the combined roof trusses by graded loading, and judgment of whether the combined roof trusses meet normal use performance requirements; and S5, reinstallation of the combined roof trusses meeting the normal use performance requirements, and realization of overall recycling. The application has the advantages of standard operation, high safety, and the like, can improve the qualified rate of truss recycling to more than 98%, improve construction efficiency by 40%, significantly reduce resource waste and engineering cost, and is suitable for the reconstruction, relocation and recycling engineering of various prestressed concrete truss structures such as industrial plants, bridges, large-scale stadiums and the like.
