Problems solved by technology

The shortcomings of this traditional method are fully exposed by infrared detection, and it will be difficult to pass the acceptance of the project quality of the main branch
The deviation of the steel bar is formed, and the thickness deviation of the steel bar cover is large
In particular, the vertical steel bars of high-rise shear walls are deviated, not vertical, the horizontal steel bars are bent, the mesh spacing deviation is large, and the steel bar cover thickness deviation is large, which does not meet the allowable deviation value range in Table 5.5.2 of GB50204-2002 and "Appendix E Structure Relevant regulations on the inspection of the thickness of the protective layer of solid steel reinforcement

Embodiment Construction

[0010] 1. General idea:

[0011] Steps: binding vertical ladder reinforcement, binding horizontal ladder reinforcement, binding vertical wall reinforcement, binding wall horizontal reinforcement.

[0012] The vertical ladder reinforcement is composed of two vertical reinforcements one level larger than the vertical reinforcement of the wall and several transverse reinforcements, and the horizontal ladder reinforcement is composed of two longitudinal reinforcements and several horizontal reinforcements.

[0013] Remove the horizontal ladder bars after pouring the concrete.

[0014] 2. The steel bar binding process is as follows: figure 1 shown.

[0015] 3. The installation process of shear wall reinforcement is as follows: figure 2 shown.

[0016] 4. Operation points:

[0017] 1. Construction preparation

[0018] According to the drawings and specification requirements, draw vertical trapezoidal ribs, horizontal trapezoidal ribs, fixed-distance frames, "∏"-shaped inner b...

Abstract

The invention discloses a steel bar bonding method of a shearing wall of a high-rise building, which relates to the technical filed of building engineering, in particular to the technical field of steel bar bonding in the construction of the shearing wall of the high-rise building. The method comprises ordinal steps of bonding a vertical ladder steel bar, bonding a horizontal ladder steel bar, bonding the vertical steel bars of a wall body and boding the horizontal steel bars of the wall body; the vertical ladder steel bar consists of two vertical steel bars and a plurality of horizontal steel bars; the horizontal ladder steel bar consists of two vertical steel bars and a plurality of horizontal steel bars; and the horizontal ladder steel bar is disassembled after concrete is poured. The method has easy operation and promotion, reduces the proportion of skillful workers, raises assembly speed, improves labor productivity, can effectively control the interval between the steel bars of walls and columns in reinforced concrete structure and the accuracy of the protective layer, and ensure the quality of assembly location of steel bar engineering.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to the technical field of binding steel bars in the construction of high-rise shear walls. Background technique [0002] Reinforcement engineering is an important sub-item of reinforced concrete engineering. The accuracy of the installation position of the steel bars is fundamental to meet the structural design requirements and ensure the quality of the main structure project. In the past, the method of binding steel bars was to adjust the spacing of the vertically thrown steel bars, bind the vertical bars, draw the distance between the horizontal bars on the vertical bars at both ends, and tie the horizontal bars. And the thickness of the protective layer, with an intuitive means of inspection. The shortcomings of this traditional method are fully exposed by infrared detection, and it will be difficult to pass the acceptance of the project quality of the main bra...
