Prefabricated assembled superposed plate type concrete shear wall and construction method thereof

Abstract

The invention relates to a prefabricated assembled superposed plate type concrete shear wall and a construction method thereof. The prefabricated assembled superposed plate type concrete shear wall comprises superposed wall plates and a cast-in-place concrete core wall, wherein each superposed wall plate is formed by superposing two prefabricated concrete single wall plates which are of the same specification and are symmetrically arranged at an equal interval; supporting plate steel bar supports are arranged between the two single wall plates; node connection reinforcement steel bars are arranged on end nodes of the superposed wall plates; the superposed wall plates are fixedly integrated with the cast-in-place concrete core wall; and the superposed wall plates, the cast-in-place concrete core wall, the supporting plate steel bars and the node connection reinforcement steel bars are fixedly connected with one another to form the shear wall structure. The invention also provides a construction method for the shear wall structure. By the construction method, when an extensive form building mode is changed, and structural members of a house are standardized and modularized, engineering construction is high in speed, and materials are saved; and the overall structural performance is high.

Description

technical field [0001] The invention belongs to the technical field of building construction, and in particular relates to a prefabricated and assembled laminated plate concrete shear wall structure and a construction method thereof. [0002] Background technique [0003] At present, the structural forms of cast-in-place concrete structures such as walls and beams and slabs are mostly wet operations, that is, after the formwork and supports are installed, the steel bars are bound, and then the concrete is poured. The erection of the formwork support should determine the strength, stiffness, spacing, step distance, etc. of the formwork support according to the joint action of the dead load and the construction load. Although the operation is not difficult, there are many procedures, a large workload, and a large amount of steel and formwork. The structural form is also not conducive to the development direction of housing industrialization. The construction of this type of ...

Problems solved by technology

The erection of the formwork support should determine the strength, stiffness, spacing, step distance, etc. of the formwork support according to the joint action of the dead load and the construction load. Although the operation is not difficult, there are many procedures, a large workload, and a large amount of steel and formwork. The structural form is also not conducive to the development direction of housing industrialization

The construction of this type of structure has high requirements on the workers' operating skills, and the installation of formwork and supports has many human and tool factors, which is arbitrarily large, and the quality of concrete molding is not easy to control; And the overall stability of the support does not meet the requirements, which is likely to cause local uneven force and deformation, which affects the forming quality of the concrete structure; Steel pipe support is uneconomical
