Abstract

The invention discloses a steel bar connecting sleeve joint and an implementation method, and belongs to the field of steel bar engineering. The steel bar connecting sleeve joint comprises a first sleeve and a second sleeve which are provided with openings at two ends, a first liner tube and a second liner tube which are provided with openings at two ends, and a center rod, and the surface of thecentral rod is provided with annular raised rib rings. The liner tubes are provided with grooves corresponding to the center rod and are inlaid with the rib rings of the center rod. The surfaces of the liner tubes are threaded and can be screwed into a sleeve with threads on the inner wall. The steel bar connection at two ends of the sleeve adopts threaded mechanical connection, the sleeve can rotate freely in the axial direction around the center rod by the liner tubes, and the steel bar connecting sleeve joint and the implementation method are suitable for various working conditions requiring the connection of steel bars.

Description

technical field [0001] The invention relates to the technical field of steel bar engineering, in particular to a steel bar connection sleeve joint and an implementation method. Background technique [0002] With the progress of the times, new technologies in my country's construction industry are also developing rapidly. In reinforced concrete construction, the mechanical connection of reinforcement is most common. The mechanical connection of steel bars can not only ensure the joint strength, but also save steel bars. [0003] The traditional steel sleeve joints are very difficult to construct, and the stress of the steel joints cannot be released, and in order to meet the requirements of various working conditions, such as: bending steel bar connection, mutual docking of cast-in-situ pile steel cages, and bridge steel bars are too long and dense, etc. , In these occasions where it is inconvenient to rotate the steel bars, various auxiliary devices need to be used, which ...
