AI Technical Summary

Technical Problem

In prefabricated structure construction, the anchoring of reinforcing bars in composite slabs affects the efficiency of reinforcing bar binding in cast-in-place beams, and the lower longitudinal reinforcement threading operation is interfered with and poses safety hazards.

Method used

Temporary fixing clamps for reinforced concrete beams using composite slabs are employed, including a rebar gripper and a threaded rod pull ring. These clamps enable temporary fixing of the lower longitudinal reinforcement bars through gripping, dragging, and hanging functions, allowing for changes in the binding sequence and expansion of the working space.

Benefits of technology

It improves the construction efficiency of composite slab cast-in-place beam structures, expands the working space, avoids space constraints after the reinforcement cage is formed, and enhances safety and ease of operation.

Abstract

This invention provides a temporary fixing clamp for reinforcing bars in cast-in-place composite slab beams, belonging to the technical field of auxiliary tools for building construction. It includes a reinforcing bar gripper and a screw pull ring. The reinforcing bar gripper is a U-shaped structure for easy gripping of reinforcing bars, with anti-slip blocks inside the U-shaped groove, and interlocking snaps and snap slots on the end face of the groove. Anti-slip handles are provided on both sides of the bottom of the gripper for easy hand pressure. The screw pull ring includes a mounting screw and a movable pull ring. The top of the gripper has a pull ring mounting threaded hole, and the bottom of the mounting screw is threaded and screwed into the pull ring mounting threaded hole, pressing the reinforcing bar against the anti-slip blocks. The movable pull ring is located at the top of the mounting screw and is used for dragging or suspending the reinforcing bar. This invention achieves temporary fixing of the lower longitudinal reinforcing bars through gripping, dragging, and suspending functions, thereby changing the binding sequence, expanding the working space, and improving construction efficiency.
