A formed steel bar product for cast-in-place concrete shear wall panels

Abstract

The invention proposes a shaped steel bar product for cast-in-place concrete shear wall panels, which includes a first layer of steel mesh sheets, a second layer of steel mesh sheets, and the first layer of steel mesh sheets and the second layer of steel mesh sheets. There are multiple groups of trapezoidal horse stool bars between; the first layer of steel mesh sheets and the second layer of steel mesh sheets are parallel to each other and there is a certain distance between them; each group of trapezoidal horse stool bars The corners of the sheet and the second-layer steel mesh are connected and fixed; each group of trapezoidal horse stool bars includes a horizontal trapezoidal horse stool bar and a vertical trapezoidal horse stool bar; the present invention greatly saves the manufacturing cost and improves the processing efficiency , It can also keep the geometric shape unchanged during the stacked transportation, hoisting and on-site installation of the shear wall formed steel bar products.

Description

technical field [0001] The invention relates to the technical field of steel bar products, in particular to a formed steel bar product for cast-in-place concrete shear wall panels. Background technique [0002] The traditional shear wall reinforcement cage is composed of two steel mesh sheets that are parallel to each other and spaced at a certain distance and tied steel bars. In terms of production, due to the large number of steel connection points, the binding workload is large. In terms of transportation, the tie bars are in the shape of hooks, which cannot limit the displacement of the steel mesh into the wall. If a highly efficient stacking and transportation method is adopted, the two layers of steel mesh are easy to stick together due to gravity during transportation. , which brings great inconvenience to the later construction. In terms of construction, due to the poor rigidity of the reinforcement cage, it is easy to deform during lifting and transportation, and ...

AI Technical Summary

Problems solved by technology

It can be seen that the traditional shear wall binding steel cage is difficult to meet the production, transportation and installation requirements in the construction process of prefabricated buildings

In addition, the traditional shear wall tying reinforcement cage requires a lot of work and time-consuming to bind the steel reinforcement, and the overall rigidity of the tying reinforcement cage is poor, and it is easy to deform during transportation and hoisting

[0003] Chinese Patent Publication No. CN 110847505 A is an invention patent, which provides a forming reinforcement cage for double-skin walls and its processing method, which discloses the first side reinforcement mesh and the second side reinforcement arranged in parallel intervals Mesh sheet and multiple vertical ladder bars, however, the vertical ladder bars used in this invention and the traditional truss bars use a large amount of steel, the manufacturing cost is high, and they are easily deformed during hoisting
