Prefabricated shear wall groove grouting anchor horizontal connection structure

Abstract

The invention provides a prefabricated shear wall groove grouting anchor horizontal connection structure. The prefabricated shear wall groove grouting anchor horizontal connection structure comprisesa first shear wall and a second shear wall which are laterally arranged side by side, and a first convex plate and a second convex plate are separately disposed on the end faces, facing each other, ofthe first shear wall and the second shear wall. First U-shaped stirrups and second U-shaped stirrups are disposed in a cavity structure in a staggered mode in the vertical direction, wherein the cavity structure is formed by the first and second shear walls and the first and second convex plates in a surrounding mode. Mouth structures formed by overlapping portions of the first and second U-shaped stirrups are provided with reinforcement cages in an inserted mode, and concrete is poured in the cavity structure. Manpower is saved, on-site operation time is reduced and construction is more simple and convenient, the staggered first and second U-shaped stirrups reduce the use of steel bars, and cost is saved; the reinforcement cages inserted in the stirrups improve the shear capacity of theshear walls, the first and second U-shaped stirrups transmit force to the reinforcement cages, and the transmission force is clear, the integrity is improved, and the shear performance is good; and when an earthquake occurs, the reinforcement cages form an embedded column in the shear walls to prevent the shear walls from collapsing.

Description

Technical field: [0001] The invention relates to the technical field of building structure connection components, in particular to a prefabricated assembly type shear wall groove grout anchor horizontal connection structure. Background technique: [0002] The innovation and development of prefabricated structural system is the core driving force for the development of housing industrialization. As a typical structural form in the prefabricated structural system, the prefabricated shear wall structure has the characteristics of fast construction speed, stable and reliable quality, energy saving and environmental protection, and is widely used in my country. [0003] When the weight of the prefabricated shear wall is too large, or the size is long, the shear wall can be set to be formed by two or more horizontal splicing. Therefore, the horizontal connection is to ensure that the prefabricated shear wall structure has sufficient bearing capacity, integrity and good ductility,...

AI Technical Summary

Problems solved by technology

These connection methods solve the horizontal connection of prefabricated shear walls to a certain extent, but there are disadvantages such as complicated construction, high cost, and poor overall performance.

However, the reserved holes for tying steel bars often require formwork during construction, and the on-site tying of steel bars is difficult to construct.

Welding and bolting require professional and technical personnel to operate, the cost is high, and the quality is not easy to guarantee
