Description

Technical Field

[0001] The present application relates to the technical field of steel bar construction, and more specifically, to a vertical steel bar positioning device for shear walls of residential buildings. Background Art

[0002] Shear wall structure construction is a common construction project in the field of building construction. Concrete pouring operations are carried out on the steel frame structure composed of vertical and horizontal steel bars, and shear wall structure construction is completed through vibration operations, maintenance operations, etc. The steel frame structure serves as the foundation of shear wall construction. The spacing between adjacent vertical and adjacent horizontal steel bars and the accuracy of steel bar positioning directly affect the quality of shear wall structure construction.

[0003] The search publication (announcement) number: CN207376967U discloses a shear wall vertical reinforcement positioning device, comprising two parallel positioning bars, each of which is provided with a plurality of positioning holes for inserting vertical reinforcement bars evenly along its length direction, an adjustment rod for adjusting the spacing between the two positioning bars is inserted between the two positioning bars, and the adjustment rod is provided with a plurality of fasteners for locking the positioning bars. This application can solve the problem that the shear wall vertical reinforcement positioning device needs to weld the end of the vertical reinforcement bar to the outside of the connection between the supporting reinforcement bar and the short limb reinforcement bar during actual use, and the short limb reinforcement bar and the supporting reinforcement bar are connected by welding, which makes the installation method complicated and leads to low working efficiency.

[0004] Moreover, the application utilizes two groups of positioning holes formed by relatively designed semi-positioning holes to achieve the clamping and positioning of the bottom end of the constructed steel bars. However, since there is a gap between the inner wall of the positioning hole and the joint of the steel bar, and the clamping and positioning of the steel bar is limited to one fulcrum, the constructed steel bar still has room to shake, which can easily lead to deviations in the position of the steel bar and reduce the overall stability of the subsequent shear wall.

[0005] In order to solve the above problems, the present application provides a vertical steel bar positioning device for shear walls of residential buildings. Utility Model Content
