Abstract

The invention provides a concrete frame column roll welding spiral stirrup reinforcement cage and a preparation method thereof, and belongs to the technical field of civil engineering. The concrete frame column roll welding spiral stirrup reinforcement cage comprises inner ring longitudinal reinforcements, inner ring polygonal spiral stirrups, middle longitudinal reinforcements, middle polygonal spiral stirrups, outer ring longitudinal reinforcements and outer ring polygonal spiral stirrups. The concrete frame column roll welding spiral stirrup reinforcement cage is roll-welded in a spot welding mode, so that the production efficiency of the concrete frame column reinforcement cage is improved, the labor amount is reduced, the steel consumption is reduced, and the building construction cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of civil engineering and relates to the design and construction of a concrete frame structure, in particular to a concrete frame column rolling-welded spiral stirrup reinforcement cage and a preparation method thereof. Background technique [0002] For the stirrups of concrete frame columns, the method of binding ordinary stirrups specified in the "Code for Design of Concrete Structures" GB50010-2010 (2015 Edition) is used in most cases at present. Consumption of labor, the first paragraph of Article 11.4.17 stipulates that when using spiral hoops, composite or continuous composite rectangular spiral hoops, the volume reinforcement ratio of the hoops in the column hoop density area can be reduced by about 20%, and the use of Spiral hoops, composite or continuous composite rectangular spiral hoops can also save about 10% of the steel consumption of common stirrup hooks, which can save 30% of steel, reduce eng...
