AI Technical Summary

Technical Problem

The existing precast pier lifting rings require steel plates to be pre-embedded at the top and middle of the pier during construction, which is a complicated process, especially since the lower steel plate is difficult to install after the main steel reinforcement has been installed.

Method used

The method of welding and fixing reinforcing bars on both sides of the pre-embedded reinforcing bars is adopted to replace the pre-embedded steel plate in the middle of the pier column. The steel plate and the fixing plate are fixed by screw connection. The lifting ring body and the reinforcing plate are added to form a cast-in-place structure, which improves stability and construction convenience.

Benefits of technology

The construction process was simplified, the stability of the lifting rings and the ease of construction were improved, and the stability and ease of operation were ensured when lifting and moving precast piers.

Abstract

The utility model belongs to the technical field of pier construction, and disclose a kind of prefabricated pier hoisting ring, including pier body, the inner wall of pier body is evenly embedded with multiple embedded reinforcing steel bars, multiple branch shape fixing reinforcing steel bars are welded side by side in the both sides of embedded reinforcing steel bar, and the fixing reinforcing steel bars of both sides are staggered arrangement, and multiple embedded reinforcing steel bars are connected between the top of fixed steel plate, and fixed steel plate is embedded in the top of pier body, the both sides of fixed steel plate are integrally formed with fixed plate, the sidewall of fixed plate and pier body is side by side provided with multiple fixed holes, and fixed bolt is screwed between corresponding fixed hole, the top of fixed steel plate is side by side connected with multiple hoisting ring body. By the above scheme, the hoisting ring currently used needs to embed steel plate at the top and middle of pier, the process is complicated, and it is not convenient to operate, especially after the main reinforcing steel bar has been constructed, the lower end steel plate construction is more difficult.
