Novel steel bar connecting full-grouting sleeve and construction method thereof

Abstract

The invention relates to a novel steel bar connecting full-grouting sleeve and a construction method thereof. The novel steel bar connecting full-grouting sleeve comprises a sleeve body and is characterized in that the novel steel bar connecting full-grouting sleeve further comprises a partition structure located in the sleeve body, the partition structure partitions a cavity in the sleeve body into a first chamber used for accommodating a first steel bar, and a second chamber used for accommodating a second steel bar and providing detection, and the sleeve body at the second chamber is provided with a grouting hole and a grout discharging hole which communicate with the second chamber. According to the novel steel bar connecting full-grouting sleeve, a traditional sleeve penetrating through a chamber is improved into two sleeves isolating the chamber, thus a part of grouting is prefabricated and completed in a factory, meanwhile, the part grouted on site is provided with a detection structure, and thus the problems of low construction efficiency and quality control are solved. The novel steel bar connecting full-grouting sleeve can be widely applied to connection construction of aprefabricated structure.

Description

technical field [0001] The invention relates to a steel bar connector and a construction method thereof, in particular to a sleeve for a steel bar connection part in a prefabricated reinforced concrete structure and a method for using the same, belonging to the field of prefabricated building construction. Background technique [0002] The existing conventional full-grouting sleeve has a sleeve body, and the inner cavity of the body is connected, and the grouting process is only carried out at the construction site once. The main problem is that, on the one hand, the steel bars at both ends of the grouting construction can only be grouted after they are sent into the sleeve, and the grouting construction required on site is difficult and inefficient; on the other hand, the connection quality of the steel bars at the sleeve is in an unmonitorable state , and there is currently no effective detection method, let alone a remedy.

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the above-mentioned defects of the prior art, the present invention provides a new steel bar connection full grouting sleeve and its construction method, by improving the traditional through-chamber sleeve into two isolated chamber sleeves, so as to realize partial The grouting anchor is prefabricated in the factory, and at the same time, a detection structure is set up on the site grouting part to solve the problems of low construction efficiency and quality control, and provide a simple remedy
