Vertical Connection Structure, Shear Wall and Construction Method of Prefabricated Stiff Concrete Shear Wall

Abstract

The present invention provides a vertical connection structure and shear wall of a prefabricated stiffened concrete shear wall. The vertical connection structure includes a left connection body and a right connection body, wherein the left connection body includes a first pre-embedded steel bar, a second A pre-embedded steel plate, a first connecting plate, and the right connecting body includes a second pre-embedded steel bar, a second pre-embedded steel plate, a second connecting plate, and a third connecting plate. In the state where the left connecting body and the right connecting body are connected and fixed, The first connecting plate is located between the second connecting plate and the third connecting plate, and is respectively welded and fixed to the second connecting plate and the third connecting plate, so as to vertically connect and fix the two-stiff concrete shear wall. The vertical connection structure and the shear wall of the assembled stiffened concrete shear wall provided by the present invention have simple structure, material saving, strong shear resistance and reliable force transmission; convenient construction operation, easy positioning control, high precision and universality Strong, can be widely used in prefabricated rigid concrete structures.

Description

technical field [0001] The present invention generally relates to the field of building structure engineering, and mainly relates to a prefabricated rigid concrete shear wall, especially a vertical connection structure of the prefabricated rigid concrete shear wall, a prefabricated rigid concrete shear wall and a construction method. Background technique [0002] Under the background of creating a "resource-saving and environment-friendly" society, it is an inevitable requirement for the development of the construction industry to transform from the traditional high-pollution and high-energy-consumption manual workshop construction method to the environmental protection and energy-saving factory-like and standardized construction method. The prefabricated stiff concrete shear wall structure is the main force to achieve this goal. The prefabricated rigid concrete shear wall structure has the characteristics of high production efficiency, good quality, and ecological environme...
