Prefabricated vertical component and sleeve grouting construction method thereof

Abstract

The invention relates to a prefabricated vertical component and a sleeve grouting construction method thereof. The prefabricated vertical component comprises a component body of a reinforced concretestructure, wherein a plurality of grouting sleeves are pre-buried in the component body, a grouting pipe and a plurality of indicating pipes arranged on the two sides of the grouting pipe are furtherpre-buried in the component body, the two ends of the grouting pipe and the two ends of the indicating pipes extend to the bottom face and the side face of the component body correspondingly and can communicate with the outer space of the component body, and the height of the connecting positions of the indicating pipes and the grouting pipe and the side face of the component body is larger than the height of the top of the grouting sleeves. According to the prefabricated vertical component and the sleeve grouting construction method thereof, the construction work efficiency is high, and supplementary grouting can be conducted, so that the engineering safety is guaranteed.

Description

technical field [0001] The invention relates to the technical field of grouting sleeve construction, in particular to a prefabricated vertical component and a sleeve grouting construction method thereof. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the late 1960s, Dr. Yu Zhanshu, an American scientist, invented the steel sleeve connector for connecting prefabricated vertical components, such as wall panels, columns, etc. After that, the grouting technology was used and applied to a 38-story prefabricated building for the first time ——In the prefabricated column connection of Ala Moana Hotel, it pioneered the connection of steel bars in vertical concrete structures through sleeve grouting technology. In the following decades, socket grouting connections were widely used in industrialized buildings in European and American countries. [0004]...

AI Technical Summary

Problems solved by technology

[0005] The inventor also found that, using the existing grouting sleeve construction technology, the bottom seams of the prefabricated components are made of soft elastic materials such as rubber and plastic strips, which are easily compressed and deformed under pressure for a long time, causing the top grout to fall back; the prefabricated components The bottom seam is not strictly leaking, causing the top slurry to fall; the air brought in by stirring and the air enclosed during grouting will turn up when standing, causing the top slurry to fall; the warehouse will cause the top slurry to fall; The liquid level may be lower than the height required by the minimum anchorage length 8d of steel bars caused by the fall

Insufficient sleeve grouting fullness brings great safety hazards to the project, and even becomes a dangerous building
