Fabricated partially-restrained steel-reinforced concrete column system and construction method thereof

YAO PANFENG

An assembly type partially-restrained steel-reinforced concrete column system comprises two prefabricated steel-reinforced concrete columns which are connected up and down and a post-pouring material. The prefabricated steel-reinforced concrete column comprises longitudinal steel ribs, prefabricated concrete, external ribs, anti-shearing pieces and flange restraining pieces. The longitudinal steel rib comprises a steel rib web and a steel rib flange; the outer ribs comprise outer transverse ribs and outer vertical ribs; the longitudinal steel ribs are arranged in the precast concrete in the vertical direction in a full-length mode. 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 concrete column and the lower steel rib concrete column are fixedly connected; the outer vertical ribs of the upper and lower assembly type partially constrained steel reinforced concrete columns are fixedly connected, discontinuously connected or disconnected; and the post-pouring material is poured at the joint of the vertically connected steel-reinforced concrete columns and is connected with the upper and lower steel-reinforced concrete columns.
