Abstract

The invention discloses a grouting sleeve for rebar connection. The grouting sleeve comprises a grouting sleeve body, a grouting cavity is arranged inside the grouting sleeve body, a thread with a first rebar inserted is arranged at one end of the grouting sleeve body and communicated with the cavity, a notch which extends out is formed in the tail end of the screw, a sleeve thread connected with a second rebar is arranged at the other end of the grouting sleeve body, a shear force ring is arranged on the outer surface of the grouting sleeve body, a grouting port is arranged at one end, close to the thread, of the grouting sleeve body, a grout outlet is arranged at one end, close to the sleeve thread, of the grouting sleeve body, and a thread is arranged on the outer surface of each of the grouting port and the grout outlet. The grouting sleeve is reasonable in design, and occlusive force of the sleeve and concrete is increased; more easiness in operation is realized in the process of production due to integral design, an externally-connected grouting pipe is enabled to be less prone to falling, an outer side die is enabled to be easier to position, and axial positioning is more accurate, so that construction quality is improved.

Description

technical field [0001] The invention relates to a steel bar connection device, in particular to a grouting sleeve for steel bar connection. Background technique [0002] Traditionally, there are three main methods of connecting steel bars: lap joints, mechanical joints and welding. However, with the development of construction, the requirements for the production of steel cages are getting higher and higher. The new requirements cannot be completed by traditional steel connection methods. When the sleeve is used, it is difficult to control the axial direction, the positioning is not accurate, and the quality of the project cannot be guaranteed. Contents of the invention [0003] In order to make up for the deficiencies of the prior art, the invention provides a grouting sleeve for steel bar connection which is easy to operate and accurately positioned. [0004] The present invention is achieved through the following technical solutions: [0005] A grouting sleev...
