AI Technical Summary

Technical Problem

In existing technologies, prestressed concrete steel bars cannot be quickly and effectively connected to hot-rolled ribbed steel bars. Traditional connecting sleeves are complex in structure and time-consuming and labor-intensive to install, and cannot guarantee the connection quality.

Method used

The system adopts a combination structure of steel bar connecting sleeve and rebar connecting sleeve, including clamping ring, joint sleeve and threaded sleeve. The steel bar is clamped by clamping ring, and the sleeves are interlocked by snap-fit ​​bar and L-shaped groove, which simplifies the installation process and improves friction.

Benefits of technology

This technology enables rapid and reliable connection between steel bars and hot-rolled ribbed steel bars, improving connection quality and production efficiency, simplifying the operation process, and ensuring the stability and reliability of the connection.

Abstract

This utility model belongs to the field of rebar connection technology, and provides a connector for steel bars and hot-rolled ribbed steel bars used in prestressed concrete pipe piles. It includes a steel bar connecting cylinder and a rebar connecting cylinder. The steel bar connecting cylinder includes a clamping ring and a connector sleeve. The bottom end of the connector sleeve is provided with an installation plate, which has through-holes at the top and bottom. The clamping ring is composed of multiple clamping pieces for clamping the steel bar. The side wall of the connector sleeve has an L-shaped groove. The rebar connecting cylinder includes a threaded sleeve with a compression rod at its bottom end and a locking rod on its side wall. In use, the steel bar is inserted into the clamping ring of the connector sleeve, the threaded sleeve is threaded to the rebar, the compression rod is inserted into the connector sleeve, and the locking rod enters the L-shaped groove. Interlocking of the two sleeves is achieved by compression and tightening. The connector has a simple and reliable structure, good connection effect, simple operation, saves labor time, improves production efficiency, and effectively ensures the quality of rebar connections.
