Embodiment 1

[0010] The sleeve body 1 of the present invention can be made by casting. In order to remove the mold smoothly, the wall thickness of the middle part of the sleeve body 1 can be greater than that of the two ends, which is more in line with the distribution rule that the internal force in the middle part of the sleeve body is large and the internal force at both ends is small. The independent cubic block-shaped protrusion 6 provided on the inner wall of the sleeve ensures the bonding effect between the steel bars 7 and 8, the grouting material and the sleeve body 1. After the grouting material is solidified and hardened, the two reserved steel bars are connected through the sleeve to form a One. The outer diameter of the elastic rubber sealing ring 2 at both ends of the sleeve body 1 is greater than the inner diameter of the sleeve body 1, and the inner diameter of the elastic rubber sealing ring 2 is slightly smaller than the outer diameter of the steel bars 7 and 8 to ensure t...

Embodiment 2

[0012] The construction method of the present invention is as follows. After the assembled prefabricated components are manufactured in the factory, the reserved steel bar 7 can be temporarily fully inserted into the sleeve body 1, and temporarily fixed with the limit bolt 3 to prevent the sleeve from being lost. During assembly construction, the limit bolt 3 is loosened. Remove the sleeve body 1, put two elastic sealing rubber rings 2 on the reserved steel bars 7 and 8 respectively, screw in the limit bolt 3 to limit the position of the steel bar 7 and the steel bar 8 in the sleeve, and put the The reserved steel bars 7 and 8 of the two assembled prefabricated components are inserted from both ends of the sleeve body 1 to a limited position, squeezed into the elastic sealing rubber ring 2, the grouting gun is connected to the grouting hole 4 through threads, and the cement-based grouting material is poured in , When grouting, the vent hole 5 should be unblocked to ensure that...

Abstract

The invention discloses a connecting and grouting sleeve for assembled prefabricated member steel bars and a construction method thereof, aims at solving the connection problem of the assembled prefabricated member steel bars and has the advantages of simplicity in construction, low cost, high strength and reliability in connection. The connecting and grouting sleeve comprises a sleeve body, sealing rings and a position-limiting bolt, wherein a grouting hole and an exhaust hole position-limiting bolt are arranged on the sleeve body, a block-like bulge is arranged on the inner wall, and the sealing rings are arranged at the two ends in the sleeve body. When prefabricated members are assembled and constructed, the position-limiting bolt is screwed in, two reserved steel bars of the assembled prefabricated members are inserted into limited positions from the two ends of the sleeve body, the elastic sealing rubber rings are squeezed in, cement-based grout is grouted from the grouting hole, and the two reserved steel bars are connected through the sleeve to form a whole. The connecting and grouting sleeve disclosed by the invention can be used for connecting the various assembled prefabricated member steel bars.

Description

technical field [0001] The invention relates to the technical field of concrete prefabricated components, in particular to a grouting sleeve for connecting steel bars of an assembled prefabricated component and a construction method thereof. Background technique [0002] In traditional cast-in-place concrete structures, the steel bars are often connected by means of lap joints, welded joints, or extruded sleeve mechanical connections. Rebar connection. The key problem is: the connection method of this kind of steel bar cannot be applied to the steel bar connection of prefabricated components. Contents of the invention [0003] The object of the present invention is to provide a connection grouting sleeve for the steel bars of assembled prefabricated components and a construction method thereof, which has the characteristics of simple construction and reliable performance. [0004] The purpose of the present invention is achieved like this. The prefabricated comp...
