Prefabricated column joint connection structure and construction method

Abstract

The invention provides a prefabricated column joint connection structure. The prefabricated column joint connection structure includes a first prefabricated column, a second prefabricated column and stirrups. The first end of the first prefabricated column and the second end of the second prefabricated column are opposite and arranged at a certain distance; and first prefabricated column steel bars protruding outward are arranged at the first end of the first prefabricated column; second prefabricated column steel bars protruding outward are arranged at the second end of the second prefabricated column. The first prefabricated column steel bars and the second prefabricated column steel bars are connected in a overlapped mode, and the stirrups are tied to the overlapped part; ultra-high performance concrete is poured between the first end of the first prefabricated column and the second end of the second prefabricated column; and the first prefabricated column steel bars and the secondprefabricated column steel bars are embedded in the ultra-high performance concrete to form integral connection. Compared with a joint connection structure of an existing solid prefabricated column, the prefabricated column joint connection structure is easy to observe during hoisting and can be hoisted quickly, and the quality of the grouting is easily guaranteed. Compared with an existing cavityprefabricated column joint connection structure, the prefabricated column joint connection structure does not require the use of special steel bar connection pieces, and the cost is lower.

Description

technical field [0001] The present disclosure relates to the field of building component construction, in particular to a prefabricated column node connection structure and a construction method. Background technique [0002] Prefabricated buildings refer to buildings assembled on site using prefabricated components. In recent years, my country's prefabricated buildings have developed rapidly, and assembled integral laminated shear wall structures have emerged as the times require. Laminated shear walls and prefabricated columns are commonly used prefabricated components. The prefabricated column joint used as the connection between prefabricated columns is an important component connection node of the prefabricated structure, which has always been a difficult point to solve for the prefabricated frame structure. [0003] The current prefabricated column joint connections are divided into prefabricated solid column joints and prefabricated cavity column joints. The struct...

AI Technical Summary

Problems solved by technology

[0004] However, the connection method of the prefabricated solid column joints currently used cannot be observed when the grouting material is injected into the sleeve, and it is difficult to ensure the construction quality

The connectors of the prefabricated cavity columns need to use special steel connectors, and the cost is relatively high
