AI Technical Summary

Technical Problem

Existing thin-walled double-steel plate concrete composite shear walls are prone to deformation during construction, affecting the verticality and flatness of the wall, especially impacting the installation of elevator shafts in high-rise buildings.

Method used

The structure employs an injection cavity between inner and outer steel plates, with the inner and outer steel plates connected by inner and outer reinforcing components and tie rod components. Combined with steel mesh and channel steel stiffeners, the strength of the steel plates and connection stability are optimized, and deformation is reduced.

Benefits of technology

It improves the verticality and flatness of the thin-walled double-steel plate concrete composite shear wall after construction, simplifies the construction process, increases the building assembly rate and construction efficiency, and reduces the project cost.
