Problems solved by technology

However, the setting of the tapered tube in the above-mentioned grouting sleeve makes the inner diameter of this part suddenly smaller. Because the steel bar has a certain rigidity, it is difficult to make the steel bar to be connected on the same straight line, and it is even impossible to extend the steel bar to the end of the sleeve. Inside, there is a defect in the force

Abstract

The invention belongs to the field of constructional engineering, and particularly discloses a grouting sleeve and a prefabricated member. The grouting sleeve comprises a sleeve body, wherein the sleeve body is provided with a grouting port and an exhaust port; two ends of the sleeve body are open; fixing members are arranged in the middle of an inner cavity of the sleeve body; the inner wall of the sleeve body is provided with steel clacks; the thicknesses of the steel clacks gradually increase from the two ends to the middle of the sleeve body; the widths of the positions, which approach the fixing members, of the steel clacks are larger than the those of positions approaching end parts. The integral rigidity of the sleeve body is increased through the arrangement of the steel clacks of the grouting sleeve. In addition, poured slurry for grouting forms a fastening structure matched with an inner hollow part and the steel clacks of the sleeve in the sleeve body; the anchoring reliability of a steel bar is greatly improved; by using the grouting sleeve and the prefabricated member, the accurate axial control and radial positioning of the steel bar can be realized; the positioning accuracy between the steel bar and the grouting sleeve is guaranteed.

Description

technical field [0001] The invention belongs to the field of construction engineering, in particular to a grouting sleeve and a prefabricated part. Background technique [0002] In the traditional cast-in-place concrete structure, the steel bars are often connected by mechanical connection methods such as lap joints, welded joints or extrusion sleeves. The construction of the steel bar connection is relatively complicated, and the steel bar connection must be completed before pouring the concrete, which cannot The connection of steel bars between prefabricated parts makes it impossible to carry out prefabricated construction. [0003] In the prior art, the steel bar connection between the prefabricated concrete building parts needs to be connected by sleeve grouting. The two connected steel bars are inserted into the metal sleeve and high-performance cement mortar is poured into the gap between the sleeve and the steel bar. After the cement mortar is hardened, the three are...
