Mixed steel rib confined concrete column structure and construction method thereof

YAO PANFENG

A mixed steel rib confined concrete column structure comprises two steel rib confined concrete columns which are connected up and down. The steel rib confined concrete column comprises longitudinal steel ribs, concrete, external ribs, anti-shearing pieces and flange restraining pieces. The longitudinal steel rib comprises a steel rib web and a steel rib flange, and the steel rib web is fixedly connected with the steel rib flange; the concrete comprises inner concrete and outer concrete; the outer ribs comprise outer transverse ribs and outer vertical ribs; the flange restraining pieces are arranged at intervals along the ends of the steel rib flanges, and the two ends of the flange restraining pieces are fixedly connected with the adjacent steel rib flanges correspondingly. The external ribs are positioned on the outer sides of the longitudinal steel ribs and the flange constraint pieces; the longitudinal steel ribs of the upper steel rib confined concrete column are fixedly connected with the longitudinal steel ribs of the lower steel rib confined concrete column, and the steel rib flanges and the steel rib webs are correspondingly arranged; and the outer vertical ribs of the upper steel rib confined concrete column are fixedly connected with the outer vertical ribs of the lower steel rib confined concrete column.
