Embodiment 1

[0023] refer to figure 1 , a grouting sleeve structure in this embodiment, including a sleeve 1, a sleeve envelope 2 arranged at the bottom of the sleeve 1, a grout hole 3 arranged at the top of the wall of the sleeve 1, a grout hole 3 arranged at the The overflow port cover 4 at the overflow port, and the structural glue 5 arranged in the sleeve 1 .

[0024] A kind of grouting sleeve structure of this embodiment, the structural adhesive 5 is packaged in the sleeve 1, and during construction, the steel bar to be connected is inserted into the sleeve 1 from the sleeve envelope 2, and the structural adhesive 5 in the sleeve 1 and After the connected steel bars are in contact, a reaction can occur to form a solidified body, thereby forming a force-transmitting structure and completing the connection between components.

[0025] The grouting sleeve structure of this embodiment, compared with the traditional grouting sleeve construction process, eliminates the grouting operation, ...

Embodiment 2

[0030] refer to figure 1 , figure 2 , the present embodiment provides a construction method of the grouting sleeve structure described in Embodiment 1, and the technical scheme is as follows:

[0031] A construction method for a grouting sleeve structure, comprising the steps of:

[0032] In the first step, the structural glue 5 is filled in the sleeve 1;

[0033] In the second step, the grouting sleeve structure is in place;

[0034] The third step is to uncover the cover 4 of the overflow port, insert the steel bar to be connected into the sleeve 1 from the sleeve cover 2, the structural glue 5 reacts with the steel bar to be connected, and forms a solid to wrap the steel bar to be connected, and completes the installation of the steel bar to be connected connect.

[0035] In the construction method of a grouting sleeve structure in this embodiment, the structural glue 5 is encapsulated in the sleeve 1. During construction, the steel bar to be connected is inserted into...

Abstract

In order to simplify the construction process of a grouting sleeve, improve the construction efficiency of the grouting sleeve and reduce the human and financial cost, the invention provides a grouting sleeve structure and a construction method. The grouting sleeve structure comprises a sleeve, a sleeve sealing sleeve, a grout overflowing hole, a grout overflowing opening sealing sleeve and a structural adhesive, wherein the sleeve sealing sleeve is arranged at the bottom of the sleeve, the grout overflowing hole is formed in the top of the sleeve wall of the sleeve, the grout overflowing opening sealing sleeve is arranged at the grout overflowing opening of the grout overflowing hole, and the structural adhesive is arranged in the sleeve. According to the grouting sleeve structure, the structural adhesive is packaged in the sleeve, a to-be-connected steel bar is inserted into the sleeve from the sleeve sealing sleeve during construction, and the structural adhesive in the sleeve can react after making contact with the to-be-connected steel bar so as to generate a solidification body, so that a force transmission structure is formed, and the connection between components is completed.

Description

technical field [0001] The invention belongs to the technical field of prefabricated assembly engineering, in particular to a grouting sleeve structure and a construction method. Background technique [0002] Grouting sleeve is one of the commonly used steel bar connection methods in prefabricated buildings in my country. During the construction process, after the ribbed steel bar is inserted into the grouting sleeve, the special grouting material is filled in the gap between the grouting sleeve and the steel bar to form a force transmission structure. [0003] The grouting sleeve has strong adaptability, but the construction process is relatively complicated, which cannot improve the grouting efficiency and reduce the cost of human and financial resources. Contents of the invention [0004] In order to simplify the construction process of the grouting sleeve, improve the construction efficiency of the grouting sleeve, and reduce human and financial costs, the invention p...
