A slip spliced ​​full grout sleeve

Abstract

The invention relates to a sliding splicing full grouting sleeve, which comprises a segmented grouting sleeve provided with a grout inlet hole and a grout outlet hole, and the segmental grouting sleeve is provided with multiple holes for centering and straightening prefabricated component steel bars. Level limiting device, wherein: the inner wall of the cylinder of the segmented grouting sleeve is provided with a pair of clamping channels along its length direction, and the multi-level limiting device includes a pair of connecting rods arranged longitudinally and arranged at intervals in sequence on both sides. A plurality of steel bar centering units between the connecting rods, the prefabricated component steel bars are inserted into the steel bar centering units; the connecting rods are matched with the clamping tracks, and the multi-stage limiting device passes through the connecting rods Inserted into the clamping channel of the segmental grouting sleeve, the sliding splicing of the multi-level limit device and the segmental grouting sleeve cylinder is realized. The grouting material is filled in the full grouting sleeve, and after the grouting material is hardened, the prefabricated component reinforcement connection is completed. The grouting sleeve has simple structure and high construction efficiency, and can be widely used in prefabricated buildings.

Description

technical field [0001] The invention belongs to the technical field of prefabricated building steel bar connection, and in particular relates to a sliding splicing full grouting sleeve. Background technique [0002] In recent years, in order to realize the modernization of green buildings and the construction industry, the country has vigorously promoted prefabricated buildings, and the reliable connection of prefabricated steel bars between prefabricated components is a key factor affecting the structural performance of prefabricated buildings. The grouting sleeve connection technology is widely used in the steel bar connection of prefabricated buildings in my country because of its reliable connection performance, fast construction speed, and good economy. It is one of the important directions for the development of prefabricated structures. [0003] At present, the grouting sleeve joints on the market can be divided into two categories: full grouting joints and semi-grout...

AI Technical Summary

Problems solved by technology

However, the grouting sleeve provided by this invention cannot ensure the centering and straightening of the prefabricated steel bars. When the steel bars stick to the wall, the positioning is not accurate, or the grouting is not dense, it is easy to lead to the pull-out damage of the steel bars, which seriously affects the assembled prefabrication. Reliability and security of component connections
