Threaded grouting sleeve suitable for side-by-side connection of double parallel bars

Abstract

The invention discloses a threaded grouting sleeve suitable for side-by-side connection of double parallel bars. The threaded grouting sleeve comprises a sleeve body. An upper sealing plug is arranged at a top opening of the sleeve body, a lower sealing plug is arranged at a bottom opening of the sleeve body, a slurry discharging hole is formed in the side face of the top of the sleeve body, a grouting hole is formed in the side face of the bottom of the sleeve body, a limiting partition is arranged in the sleeve body, the lower parts of two upper end steel bars penetrate through the upper sealing plug to be inserted into the sleeve body and then make contact with the limiting partition, the upper parts of two lower end steel bars penetrate through the lower sealing plug to be inserted into the sleeve body and then make contact with the limiting partition, grouting materials are poured into the sleeve body, a plurality of shear keys and a plurality of threaded ribs are arranged on the inner wall of the sleeve body, and the limiting partition is of a cross-shaped structure. The threaded grouting sleeve can be suitable for parallel bar connection and is high in reliability.

Description

technical field [0001] The invention belongs to the field of prefabricated building construction, and relates to a threaded grouting sleeve suitable for parallel connection of double parallel ribs. Background technique [0002] In the design of some long-span or high-rise structures and structures bearing heavy equipment loads, such as bridges, viaducts in rail transit, elevated stations, etc., in order to reduce the self-weight of the structure while ensuring the ductility of the bearing capacity and other requirements, the cross-sectional size of the components is often controlled, and then Due to the large amount of self-reinforcement and tight arrangement, it is difficult for the spacing of steel bars to meet the minimum clear spacing requirements in the code; in addition, the dense steel bars will make it difficult to arrange and bind during the construction process, and it is difficult to vibrate concrete pouring. [0003] In order to solve the problems in the above-me...

AI Technical Summary

Problems solved by technology

[0004] The emergence of combined reinforcement is mainly to solve the following reinforcement arrangement problems: 1. Cannot obtain sufficient diameter reinforcement or the reinforcement is limited according to the clear distance requirements; 2. The structural reinforcement is designed according to the clear distance limit and calculation needs, but cannot be arranged In the required position; 3. Dense reinforcement layout makes concrete pouring difficult
