specific Embodiment 2

[0031] refer to Figure 4 The characteristics of the specific embodiment 2 of the present invention are: the zigzag-shaped tie bars 2 are composed of several sections of V-shaped tie bars, and the lengths of the two sides of each V-shaped tie bar meet the overlapping length, and are formed by welding or mechanical connection. Make each section of V-shaped tie bars form a continuous zigzag tie bar. Welding or mechanical connection is used to make each section of V-shaped tie bars form a continuous zigzag tie bar. All the other are with specific embodiment 1.

Abstract

The invention relates to a shear wall with a continuous zigzag tie bar structure. The shear wall comprises a concrete wall body and a steel bar structure built in the concrete wall body, and is characterized in that the steel bar structure is formed by connecting a plurality of tie bars, a plurality of vertical distribution bars and a plurality of horizontal distribution bars; the vertical distribution bars are vertically and parallelly ranged into two rows; zigzag tie bars are arranged in the two rows of vertical distribution bars from top to bottom; a cuspidal point of each zigzag tie bar is fixedly connected with the vertical distribution bars to form a three-dimensional framework structure; the horizontal distribution bars are arranged at the outer side or the inner side of the vertical distribution bars from top to bottom; and in the zigzag tie bars, the cuspidal point(s) of one or a plurality of zigzag tie bars is(are) fixedly connected with the adjacent horizontal distribution bars to form a three-dimensional shear wall truss structure with a one-layer or multi-layer horizontal frame body structure. The shear wall can solve the problems that the steel consumption is great; the restriction of the tie bars and the horizontal distribution bars on the vertical distribution bars is insufficient; and the effect of improving the ductility of the shear wall cannot be achieved. The shear wall has the beneficial effects that the steel bar overturning in the construction period can be prevented; the cost is low; and the ductility is high.

Description

technical field [0001] The invention relates to a shear wall, in particular to a shear wall with a continuous zigzag lacing structure, and belongs to the technical field of building structures. Background technique [0002] At present, shear walls are formed by pouring concrete on the basis of steel cages. Since the vertically distributed reinforcement is in a cantilever state when making the reinforcement cage, it is easy to topple over and affect the construction. [0003] In the prior art, it is generally adopted to increase the size of the vertical reinforcement to solve this problem, that is, the diameter of the vertical distribution reinforcement is required to be not less than 10mm; however, this requirement not only increases the steel consumption, but also does not fundamentally Above all, it solves the problem that the vertical distribution bars are always in a cantilever state, so that the lead wires fall over, and the effect of preventing the overturning of the ...
