Problems solved by technology

In addition, the mortar block is easy to break and fall off, so the position of the shear wall reinforcement and the thickness of the protective layer are difficult to guarantee
In addition, the Chinese patent also discloses a steel bar fixing bracket with a patent number of ZL91206901. Due to structural limitations, the frame has no elasticity at the bayonet and cannot accommodate steel bars of various diameters. In addition, the length between the two supports Not adjustable, resulting in too many models, difficult processing and other disadvantages

Embodiment Construction

[0017] According to the accompanying drawings, the embodiment is further described. The plastic bracket for positioning the steel bars in the shear wall is made of engineering plastics. The left and right two groups of steel bar positioning members 2 are threaded connections, and the extension rods 4 can be made into different lengths of 50mm and 100mm. The length of the bracket is determined according to the thickness of the shear wall. The wheeled structure of the reinforcing bar positioning member 2 is provided with an elastic bayonet, and an elastic card 3 is arranged in the bayonet, and a groove is provided on the outer surface of the straight rod part. The outer side of the wheel rim of the wheel structure of the steel bar positioning member 2 is provided with three convex points 1 . When in use, after the double rows of steel bars in the shear wall are bound, choose a plastic frame of appropriate length, perpendicular to the double rows of steel bars, and just clamp the ...

Abstract

A plastic frame for locating the reinforcing bar and arranging protecting layer of shear wall is made of engineering plastics. The left and right locating members are connected by spiral thread and have wheel-type unit with elastic opening and elastic fastening piece. Its straight rod has slots on its external surface. Its advnatages are high strength, elastic and reliability and precise size.

Description

technical field [0001] The invention belongs to the technical field of building components, in particular to a plastic bracket used for positioning steel bars of a shear wall. Background technique [0002] In the prior art, the shear wall structure is a concrete structure type commonly used in high-rise buildings, and the shear wall reinforcement is double-row reinforcement. In previous constructions, S-shaped steel bars were often used as tie bars to control the spacing of double-row steel bars, and mortar pads were used to protect the thickness of the steel bar cover. Because the tie bars can only control the double steel bars not to deviate outward, but not to control their inward deviation. In addition, the mortar block is easy to break and fall off, so the position of the shear wall reinforcement and the thickness of the protective layer are difficult to be guaranteed. In addition, the Chinese patent also discloses a steel bar fixing bracket with a patent number of ZL...
