AI Technical Summary

Technical Problem

In existing building construction, the positioning of tie bars is inaccurate and the installation efficiency is low. Furthermore, the existing fixing devices are difficult to adapt to changes in wall thickness and bar diameter, making them prone to loosening and affecting structural quality.

Method used

A wall tie bar positioning clamp was designed, which consists of a clamp body, a fixed clamp arm, a movable clamp arm, and an adjustment component. It uses L-shaped claws to clamp the wall and arc-shaped clamps to hold the steel bars. Combined with the adjustment screw and guide rod, it achieves precise positioning and reliable locking.

Benefits of technology

It ensures the accurate positioning of the tie bars, prevents loosening, adapts to bars of different diameters, improves installation efficiency and the overall integrity and seismic performance of the structure, and is suitable for various building scenarios.
