Grouted overlapping assembly type reinforced concrete shear wall structure and method for building grouted overlapping assembly type reinforced concrete shear wall structure

Abstract

The invention discloses a method for building a grouted overlapping assembly type reinforced concrete shear wall structure, belongs to the field of buildings and relates to an improvement on a design and construction method of an existing assembly type concrete structure. The structure of a cast-in-place reinforced concrete shear wall is subjected to design splitting and is split into a plurality of structural components; a hollow hole which can be of any shape is reserved in each shear wall component in the vertical direction; the inner wall of each hole and the horizontal direction connection end part of the shear wall are provided with anti-shear sliding key slots; the prefabrication production of the structural component is completed in a prefabricated component factory, the structural components are transported to the engineering construction field to be lifted and installed; after the structural components are positioned and fixed and a small number of post-poured connection joints are subjected to form erecting, the components are subjected to horizontal and vertical splicing and then the structural components are subjected to grouted concreting overlapping, so that the structural components are combined into one whole body.

Description

technical field [0001] The present invention relates to buildings, in particular to building concrete structure engineering, in particular to a prefabricated concrete structure system. "The construction method of the reinforced concrete house with the prefabricated shear wall structure of pouring core. Background technique [0002] At present, residential buildings such as high-rise residences and apartments mostly adopt shear wall (seismic fortified area is called seismic wall) structure. In recent years, with the adjustment of the national construction industry policy, the prefabricated concrete shear wall structure has emerged. For example, Vanke has introduced Japan’s superimposed cast-in-place wall technology ("New Developments in Construction Technology of Prefabricated Concrete Structures for Housing Construction", "Construction Technology", Guo Zhengxing, Volume 40, Issue 342, June 2011), and the prefabricated side of the shear wall It can also be used as a formwor...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the problems of the existing prefabricated concrete shear wall structure construction methods, such as low industrialization degree and low construction efficiency, difficult quality assurance, overly complicated process and high construction cost, the present invention proposes a core-filling and prefabricated prefabricated reinforced concrete shear wall construction method. The construction method of the force wall structure house, that is, the factory prefabricated concrete hollow shear wall components, through a small amount of cast-in-place concrete connection nodes and the method of pouring laminated concrete on the hollow parts of the prefabricated concrete hollow shear wall components, to achieve the realization of each The overall connection of prefabricated components achieves the purpose of being equivalent to cast-in-place concrete structures
