AI Technical Summary

Technical Problem

When constructing existing steel reinforcement cages in confined spaces, there are problems such as multiple welding sections, long construction period, complicated procedures, and low efficiency, especially when the construction is near sensitive areas, the construction complexity is high.

Method used

The design adopts an inwardly folding flexible steel cage. Through the interlocking of the main connectors and reinforcing stirrups, and utilizing the triangular support structure of the support rods and rotating seats, the steel cage can be folded inward and stretched stably, reducing welding joints and improving convenience and stability.

Benefits of technology

It effectively solves the construction problem of steel cages in narrow spaces, improves construction efficiency, simplifies procedures, shortens construction cycle, and enhances the overall stability and ease of use of steel cages.

Abstract

The invention discloses a flexible reinforcement cage capable of being folded inwards, and relates to the technical field of low-clearance foundation construction, the flexible reinforcement cage comprises main reinforcements and reinforcing stirrups, the reinforcing stirrups are sleeved with a plurality of main connecting pieces, and the main connecting pieces are matched with the main reinforcements in an inserted connection mode; a plurality of stirrup connecting pieces are further arranged on the reinforcing stirrups, each stirrup connecting piece comprises a stirrup sleeve, each stirrup sleeve is provided with a connecting hole in sliding connection with the corresponding reinforcing stirrup, a supporting rod is fixed to each stirrup sleeve, and the supporting rods on every two adjacent reinforcing stirrups are hinged and matched with each other; and at least two supporting rods are arranged on each group of stirrup connecting pieces and are used in a running fit manner. The construction complexity of the reinforcement cage in the narrow space is reduced, and the use convenience of the reinforcement cage in the narrow space is improved.
