Ladder rib for controlling spacing of vertical reinforcement of shear wall and using method thereof

Abstract

The invention discloses a ladder rib for controlling the spacing of vertical reinforcement of a shear wall. The ladder rib comprises two horizontal ladder ribs, a plurality of step ribs and a plurality of nuts. The ladder rib is characterized in that the two horizontal ladder ribs are arranged in parallel, the lengths of the two ladder ribs are the lengths of a wall section of the shear wall section plus 100mm. The multiple step ribs are fixedly welded between the inner sides of the two ladder ribs at equal intervals. A plurality of nut bodies are in a hexagonal shape, threaded holes are formed in nut bodies, the side walls of the nut bodies are fixedly welded on outer sides of horizontal ladder ribs at the welded joints of the two horizontal ladder ribs and the step ribs, and the verticalreinforcement can pass through the threaded holes of the nuts when the ladder rid is used. The ladder rib for controlling the spacing of the vertical reinforcement of the shear wall and a using method thereof have the advantages that a novel horizontal ladder rib device is simple in structure and convenient to use, the labor is saved, the construction is fast, the efficiency is high, the construction quality is safe and reliable, the installation quality of wall ribs are effectively ensured, materials are saved, environmental protection is achieved, the horizontal ladder ribs can be reused, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a ladder bar for positioning the steel bar of a wall, in particular to a ladder bar for controlling the vertical bar spacing of a shear wall and a method for using the same. Background technique [0002] Controlling the spacing of vertical steel bars in concrete shear walls has always been a key point in the installation of wall steel bars, which has attracted widespread attention from colleagues in the industry. [0003] Chinese patent CN202380642U disclosed a ladder bar for shear wall structures on August 15, 2012, in which a pair of main bars arranged on the left and right sides and parallel to each other and a plurality of vertical and fixed connections between the two main bars And along the extension direction of the main reinforcement, the stepping ribs are distributed at intervals in sequence; the stepping ribs located at the two ends and the middle of the main rib are the top mold ribs, and the stepping ribs located at...

AI Technical Summary

Problems solved by technology

However, the ladder bars still need to be fixed with the vertical bars of the shear wall with iron wires during use, and it is difficult to ensure that the vertical bars of the shear wall do not deviate

[0005] The design of traditional horizontal ladder bars is relatively simple, and it is more troublesome to bind, which will easily affect the construction progress

Due to the different qualities of operators, the quality of construction is difficult to control the qualified rate of steel bar spacing

[0006] Therefore known ladder bar exists above-mentioned various inconveniences and problems in the fixed mode of shear wall vertical reinforcing bar and iron wire binding
