PC structure grouting sleeve connection construction method

Abstract

The invention belongs to the field of structural connection of fabricated buildings, particularly relates to a PC structure grouting sleeve connection construction method, and aims to solve the technical problems that the field connection quality is difficult to meet the design requirement due to less research on the existing field connection construction process of the fabricated building structure and lack of strict field construction quality control regulations and specifications. According to the scheme, one end of grouting sleeve connection is connected through sleeve grouting, when a component is hoisted, a ribbed steel bar reserved in a base layer needs to be inserted into a reserved sleeve of a PC component, then the position of the steel bar is adjusted through the modes of perpendicularity, elevation, positioning and the like, the component is temporarily fixed, after the strength of a grouting material meets the requirement, grouting material mixtures are injected through grouting holes, grouting is stopped when grout flows out of the grout outlets, and the grouting holes and the grout outlets are blocked. The basic materials of the grouting materials are cement, and the grouting materials also comprise an additive, fine aggregate and other materials, and a proper amount of water is added and stirred.

Description

technical field [0001] The invention relates to the technical field of structural connection of prefabricated buildings, in particular to a PC structure grouting sleeve connection construction method. Background technique [0002] In recent years, prefabricated buildings have developed rapidly during the current upgrading and transformation of the construction industry due to their advantages such as energy saving and environmental protection, low labor costs, and simple construction processes. One of the basic design concepts of prefabricated concrete structures is equivalent to cast-in-place, and the key to its realization lies in the interconnection between prefabricated components. [0003] According to the research results on the seismic performance and connection forms of prefabricated concrete structures at home and abroad, a reasonable connection method can improve the reliability of the connection quality of key nodes of the building structure, making the organic an...

Problems solved by technology

However, at present, there are few researches on the construction technology of the on-site connection of prefabricated building structures at home and abroad, and the lack of strict on-site construction quality control procedures and specifications makes it difficult for the on-site connection quality to meet the design requirements.
