Grouting sleeve joint bar adjusting method

Abstract

The invention discloses a grouting sleeve joint bar adjusting method, and relates to the technical field of fabricated concrete buildings, in particular to the grouting sleeve joint bar adjusting method. The grouting sleeve joint bar adjusting method comprises the following steps that S1, the center position of a steel bar is adjusted; S2, the steel bar elevation reference surface is determined; and S3, joint bars are adjusted. According to the grouting sleeve joint bar adjusting method, rust, concrete and other sundries on the surface of the joint bars can be automatically removed, the cleanliness of the surface of the connected steel bar is kept, the connecting effect of the steel bar and sleeve grouting material is improved, therefore the stress and force transmission capacity of the steel bar is enhanced, and the structural safety is improved; straightening and cutting of the steel bar can be rapidly achieved, the construction efficiency is improved, the labor investment is reduced, the construction period is shortened, and the original intention of fabricated rapid construction is achieved.

Description

technical field [0001] The invention relates to the technical field of prefabricated concrete buildings, in particular to a grouting sleeve insertion bar adjustment method. Background technique [0002] The prefabricated building is a building assembled from prefabricated components on the construction site. It is more and more widely used because of its remarkable characteristics such as high construction efficiency, low cost, safety and reliability, energy saving and environmental protection. [0003] Existing prefabricated concrete buildings generally use the steel sleeve grouting connection technology to connect prefabricated components and floors, but the grouting sleeves embedded in the floors often have the following problems: [0004] 1) The surface of the steel bar is easily polluted by the cast-in-place concrete on the upper layer of the laminated slab; [0005] 2) The surface of the steel bar is susceptible to corrosion due to the influence of air, moisture, etc....

AI Technical Summary

Problems solved by technology

[0004] 1) The surface of the steel bar is easily polluted by the cast-in-place concrete on the upper layer of the laminated slab;

[0005] 2) The surface of the steel bar is susceptible to corrosion due to the influence of air, moisture, etc.;

[0006] 3) The positioning of the steel bars is not accurate;

[0008] 5) The steel bars are too long, which prevents the prefabricated components from falling to the specified elevation

[0009] These problems lead to the deterioration of the grouting connection effect of the steel bar sleeve, which affects the force bearing and force transmission effect of the connected steel bar, thereby affecting the structural safety. At the same time, due to the need to adjust the position, anchorage length, verticality, etc. This increases the construction cost, prolongs the construction period, and generally uses cutting machines or electric welding machines when adjusting the anchorage length of the connected steel bars, which poses safety hazards and increases cost input
