The invention belongs to the technical field of prefabrication and assembly engineering, and particularly relates to a grouting sleeve structure and a construction method.

Background

The grouting sleeve is one of the common reinforcing steel bar connection modes of the assembly type building in China at present. In 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, so that a force transmission structure is formed.

The grouting sleeve has strong adaptability, but the construction process flow is more complicated, and the grouting efficiency cannot be improved and the manpower and financial cost cannot be reduced.

Disclosure of Invention

The invention provides a grouting sleeve structure and a construction method, aiming at simplifying the construction process of a grouting sleeve, improving the construction efficiency of the grouting sleeve and reducing the cost of manpower and financial resources.

The technical scheme of the grouting sleeve structure is as follows:

According to the grouting sleeve structure, the structural adhesive is packaged in the sleeve, during construction, a steel bar to be connected is inserted into the sleeve from the sleeve cover, the structural adhesive in the sleeve can react with the steel bar to be connected after contacting, a solidified body is generated, a force transmission structure is formed, and connection between components is completed.

Compared with the traditional grouting sleeve construction process, the grouting sleeve structure provided by the invention has the advantages that the grouting operation is omitted, the grouting sleeve construction process is simplified, and the grouting sleeve construction efficiency is improved.

Furthermore, the grouting sleeve structure further comprises a connecting groove arranged at the top of the sleeve. The connecting groove is used for connecting the upper reinforcing steel bars.

Further, the grout sleeve structure, specifically, the interface of spread groove is straight screw thread.

Further, in the grouting sleeve structure, the sleeve jacket is a one-way jacket. After the sleeve envelope is arranged into a unidirectional envelope, the sleeve envelope can be opened after being subjected to certain pressure from the outside. The steel bar to be connected can be directly inserted into the sleeve from the sleeve cover, so that the construction process is simplified.

The invention also provides a construction method of the grouting sleeve structure, and the technical scheme is as follows:

a construction method of a grouting sleeve structure comprises the following steps:

firstly, filling structural adhesive in a sleeve;

secondly, placing a grouting sleeve structure in place;

and thirdly, uncovering the slurry overflow port envelope, inserting the steel bar to be connected into the sleeve from the sleeve envelope, reacting the structural adhesive with the steel bar to be connected to form a solid to wrap the steel bar to be connected, and completing the connection of the steel bar to be connected.

According to the construction method of the grouting sleeve structure, the structural adhesive is packaged in the sleeve, during construction, the steel bar to be connected is inserted into the sleeve from the sleeve cover, the structural adhesive in the sleeve can react with the steel bar to be connected after contacting, a solidified body is generated, a force transmission structure is formed, and connection between components is completed.

Compared with the traditional grouting sleeve construction process, the construction method of the grouting sleeve structure omits grouting operation, simplifies the construction process of the grouting sleeve, and improves the construction efficiency of the grouting sleeve.
