AI Technical Summary

Technical Problem

When fabricating steel cages inside a foundation pit, workers face safety threats such as poisoning, falls, and being struck by objects. Existing technologies make it difficult to safely and efficiently complete the fabrication of steel cages outside the foundation pit.

Method used

A modular rebar cage fabrication device is adopted, which connects multiple modular rebar cages outside the foundation pit and uses components such as clamping parts, rotating rings and transmission wheels to achieve unmanned lowering of the rebar cages into the pit, ensuring safe production.

Benefits of technology

This avoids risks such as gas poisoning, falls, and collapses, improves production speed and construction precision, ensures the safety of workers, and enhances the efficiency and quality of steel cage production.

Abstract

This invention relates to the field of rebar cage fabrication technology, specifically to a modular rebar cage fabrication device, comprising a base, a support member fixedly installed on the upper end of the base, a positioning ring fixedly connected to the upper end of the support member, and multiple sets of transverse moving members movably arranged inside the positioning ring, each transverse moving member having a clamping member fixedly connected to its inner side: an inner ring expansion ring unit located outside the transverse moving members, an expansion groove provided on one side of the inner ring expansion ring unit, and an expansion member provided on the other side of the inner ring expansion ring unit, the inner ring expansion ring unit being used to move the position of the clamping members after the two sets of modular rebar cages are joined; and a fixing ring located outside the positioning ring. This invention, through the proposed modular rebar cage fabrication device and its method of use, first divides the rebar cage into sections, and then uses the modular rebar cage fabrication device to join multiple sections of the modular rebar cage outside the foundation pit, achieving unmanned operation throughout the entire rebar cage fabrication process.
