Reinforcing steel bar sleeve glue pouring connection structure and construction method

Abstract

The invention discloses a reinforcing steel bar sleeve glue pouring connection structure. The connection structure comprises a sleeve and a binder used for connecting reinforcing steel bars, the two ends of the sleeve are each provided with a connector facilitating insertion of the reinforcing steel bars, the middle of the sleeve is further provided with a pouring hole used for pouring the binder, and a screw thread used for increasing the bite force of the binder is further arranged in the sleeve. During use, through the steps of sleeve installation, binder inspection, binder pouring, maintenance, fixing material removal, quality inspection and the like, the steel bars are connected, the bonding effect of the binder is fully played, the defects of steel bar welding and mechanical connection are overcome, the construction is feasible, the quality is ensured to be reliable, and the economical efficiency is high.

Description

technical field [0001] The invention relates to the technical field of steel bar connection, in particular to a steel bar sleeve glued connection structure, and in particular to a construction method of the steel bar sleeve glued connection structure. Background technique [0002] The traditional process of steel bar connection is generally divided into three connection methods: welding, mechanical connection and binding. These three connection methods of steel bars have their own scope of application and corresponding shortcomings: [0003] 1. The binding connection is not suitable for steel bars with a diameter greater than 20mm, the connection strength is low, it is not suitable for tension members, and the length of the steel bar overlap is long, generally reaching 40 times the steel bar diameter, which consumes a large amount of steel bars; [0004] 2. The mechanical connection needs to be equipped with special equipment and corresponding sleeves, which is not easy to o...

AI Technical Summary

Problems solved by technology

[0003] 1. The binding connection is not suitable for steel bars with a diameter greater than 20mm, the connection strength is low, it is not suitable for tension members, and the overlapping length of the steel bars is long, generally reaching 40 times the diameter of the steel bars, which consumes a large amount of steel bars;

[0004] 2. The mechanical connection needs to be equipped with special equipment and corresponding sleeves, which is not easy to operate on site and takes a long time;

[0005] 3. The steel bar welding process consumes electricity and belongs to hot work, which will produce more waste gas, flash and other pollution, which will affect the health of welders
