Rectangular-section steel-bar framework with variable-pitch continuous stirrups and forming method of rectangular-section steel-bar framework
The invention discloses a rectangular-section steel-bar framework with variable-pitch continuous stirrups. The rectangular-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 rectangular 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 'tian'-shaped and meshed stirrup structure. The forming method comprises the following steps: compressing the variable-pitch continuous stirrups, storing, perfuming distributing and positioned supporting on the main bars, releasing the stirrups, and fixing the distributed stirrups and main-bar nodes. The rectangular-section steel-bar framework and the forming method disclosed by the invention have 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.
