Z-shaped fabricated core column steel plate shear wall and assembly construction method thereof

Abstract

The invention relates to a Z-shaped fabricated core column steel plate shear wall. The shear wall comprises square edge stiffening columns, circular core columns, flat steel tie rods, webs and concretes, a plurality of circular core columns are uniformly distributed in a Z shape to form a Z-shaped core column wall body, square edge stiffening columns are arranged at the corner and the top of the wall body, the square edge stiffening columns are welded with the circular core columns through the webs by groove penetration welding, two outer side surfaces of the wall body are evenly provided witha plurality of flat steel tie rods, two ends of the flat steel tie rods are respectively welded on the adjacent two core columns, and the outer portions of the circular core columns and the square edge stiffening columns are filled with concretes; four gaps are symmetrically formed in upper ends of the circular core columns and the square edge stiffening columns, and downward shrinking trumpet-shaped throats are formed in the lower ends of the circular core columns and the square edge stiffening columns. The shear wall has good overall performance, simple manufacture and convenient splicing,work efficiency is improved, simultaneously the connection strength between components is high, structure safety performance is high, and anti-seismic performance is good.

Description

technical field [0001] The invention relates to the technical field of construction, in particular to a Z-shaped assembled core column steel plate shear wall and an assembly construction method thereof. Background technique [0002] Building industrialization is a low-carbon, green, environmentally friendly and efficient construction method.

Problems solved by technology

[0003] At present, for prefabricated buildings, there are two main issues affecting structural safety: 1. Seismic performance of components; 2. Connection strength between components

In order to improve the seismic performance of traditional reinforced concrete shear walls, a large number of steel bars need to be configured to resist seismic shear forces. At present, when prefabricated shear walls are manufactured and processed in factories, the steel mesh and steel cages have not been fully automated. Still rely on manual binding, low production efficiency, difficult to guarantee quality, high labor costs, and difficult to meet the needs of automated pouring production lines

At present, the connection between traditional prefabricated reinforced concrete shear wall components mostly adopts grouting sleeve connection, grout anchor connection and other forms. The above connection forms require high processing precision of components, difficult construction and low efficiency. At the same time, due to internal grouting If the quality is not well controlled, it will seriously affect the connection strength between components and reduce the safety performance of the overall structure
