Polygonal section steel-bar framework with variable-pitch continuous stirrups
The invention discloses a polygonal section steel-bar framework with variable-pitch continuous stirrups. The polygonal section steel-bar framework comprises main bars arranged longitudinally and spiral stirrups confined on the main bars, wherein the main bars are arranged by a plurality of steel bars in a manner of polygonal section; the spiral stirrups are continuously bent into polygonal spiral lines to be confined on the main bars by one steel bar so as to form a staggered and meshed stirrup structure; the quantity, the shape and the size of the main bars and the stirrups are determined by the strength and the size of building members such as beams and columns formed by the steel-bar framework according to the corresponding specifications; metal-wire binding or welding is adopted for node connection of the main bars and the spiral stirrups confined on the main bars. The polygonal section steel-bar framework disclosed by the invention has the advantages that the constraining capability of the steel bars on concrete can be enhanced and simultaneously the automation level for forming the steel-bar framework can be improved.
