Steel reinforcement cage for multi-ribbed composite wall and method for installing steel reinforcement cage

Abstract

The invention provides a steel reinforcement cage for a multi-ribbed composite wall and a method for installing a steel reinforcement cage. The steel reinforcement cage comprises a longitudinal reinforcement, a first semicircular stirrup, a second semicircular stirrup and a positioning closed stirrup, wherein the first semicircular stirrup is in the shape of a groove the lower / right end of which is opened; the second semicircular stirrup is in the shape of a groove the upper / left end of which is opened; two side edges of the first semicircular stirrup and the second semicircular stirrup are respectively perpendicular to the bottom edges of the first semicircular stirrup and the second semicircular stirrup, and the ends of the two side edges are bent to the interiors of the grooves; the stirrup surfaces of the first semicircular stirrup, the second semicircular stirrup and the positioning closed stirrup are respectively mutually perpendicular to the trending direction of the longitudinal reinforcement; and the positioning closed stirrup is horizontally bundled around the whole longitudinal reinforcement, the first semicircular stirrup is horizontally bundled around the upper / left half part of the longitudinal reinforcement, and the second semicircular stirrup is horizontally bundled around the lower / right half part of the longitudinal reinforcement. The steel reinforcement cage and method provided by the invention have the advantages of reducing the workload for bundling reinforcements applied to reinforced concrete member or structure construction sites, and accelerating the construction speed.

Description

Technical field [0001] The invention relates to the technical field of building structures, in particular to a steel cage used in a multi-ribbed composite wall and a method for installing the steel cage. Background technique [0002] Reinforced concrete components or structures are composed of steel cages and concrete. The steel cages are composed of longitudinal steel bars and stirrups. After the steel cages are tied, concrete is poured to form a reinforced concrete component or structure. Traditional steel cages are formed by tying longitudinal steel bars and closed stirrups at the component or structure construction site by workers. That is, first locate the longitudinal steel bars in the component or structure, then locate the closed stirrups, and finally Close the stirrups and the longitudinal steel bars for binding to form a steel cage. [0003] With the development of building structure technology, new structural systems with multi-ribbed composite walls, grid seismic walls...

AI Technical Summary

Problems solved by technology

[0006] (1) The binding process is very complicated, due to the large number of rib beams and rib columns, and the large number of beam-column nodes, and the reinforcement cage composed of longitudinal steel bars and closed stirrups must be formed by workers on-site binding

Therefore, it takes a lot of manpower and man-hours to bind the reinforcement cage at the construction site. The traditional arrangement of the reinforcement cage and the binding method determine that the construction speed of the manual binding of the reinforcement is difficult to be substantially improved;

[0007] (2) Due to the method of binding steel cages by workers at the construction site, it is difficult to guarantee the quality of binding due to the influence of on-site construction conditions such as high-altitude binding operations and bad weather binding operations.
