Embodiment Construction

[0054] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts are all related to the protection scope of the present invention.

[0055] like Figure 1 to Figure 4 As shown, this embodiment proposes a prefabricated building grouting sleeve connector for connecting steel bars, including

[0056] The first sleeve 1 has a first reinforcement channel 101 and a second reinforcement channel 102. The first reinforcement channel 101 and the second reinforcement channel 102 are arranged along the axial direction of the first sleeve 1 and are located at both ends of the first sleeve 1 respectively....

Abstract

The invention relates to the technical field of grouting sleeve connection, and proposes a prefabricated building grouting sleeve grouting system, including a prefabricated building grouting sleeve connector for connecting steel bars, including a first sleeve with a first steel bar channel and the second steel bar channel, the first steel bar channel and the second steel bar channel are arranged axially along the first sleeve, respectively located at both ends of the first sleeve, and the second sleeve is arranged at In the first sleeve, a first cavity is formed between the second sleeve and the first sleeve, the second sleeve has a second cavity, and the second sleeve has several outlets. One end of the discharge port communicates with the first cavity, the other end communicates with the second cavity, and both the first reinforcement channel and the second reinforcement channel are connected to the second cavity connected. Through the above technical solution, the problem of insufficient slurry density in the grouting sleeve in the prior art, which leads to a decrease in the connection strength of the steel bars, is solved.

Description

technical field [0001] The invention relates to the technical field of building grouting sleeve connection, in particular to a prefabricated building grouting sleeve grouting system. Background technique [0002] The grouting sleeve is also called grouting sleeve joint or sleeve grouting joint. The grouting sleeve is a combination of specially processed sleeves, matching grouting materials and steel bars. When connecting steel bars, fast-hardening non-shrinking grouting materials are injected, and the steel bars and sleeves are connected by the bonding and occlusal effect between the materials. The sleeve grouting joint has the advantages of reliable performance, wide applicability and easy installation. Grouting sleeve connection technology is suitable for reinforced concrete structure engineering, steel structure engineering, bridge engineering, offshore oil drilling platform engineering, offshore wind power tower and other fields. The grouting sleeve connection technolo...
