Connecting and manufacturing method of steel frame column and concrete column foot
The invention discloses a connecting and manufacturing method of a steel frame column and a concrete column foot. The steel frame column and a bottom plate are connected through fillet welds with the same welding foot size, abdomen stiffening rib steel plates are arranged on two sides of a web of the steel frame column, two flange stiffening rib steel plates are correspondingly arranged on two sides of a flange of the steel frame column, and a base plate and the bottom plate are connected through mounting welds. A hole is formed in the base plate, a foundation anchor bolt is arranged in the hole in a penetrating mode and adopts double nuts, an anti-shearing key for bearing column foot shearing force is welded to the lower part of the bottom plate, the anti-shearing key adopts an I-shaped section, a peripheral concrete column with a square section is arranged below the bottom plate, and the section size of the peripheral concrete column is larger than that of the steel frame column. Non-shrinkage fine aggregate concrete is poured between the steel frame column and the peripheral concrete column, a plurality of longitudinal steel bars are evenly distributed on the periphery of the non-shrinkage fine aggregate concrete, and the longitudinal steel bars are fixed through stirrups. The stress condition of the column foot is met, and the column foot is good in stability, ductility and fatigue performance.
本发明公开了一种钢框架柱与混凝土柱脚的连接及制造方法，钢框架柱与底板用相同焊脚尺寸的角焊缝连接，腹部加劲肋钢板设置在钢框架柱的腹板的两侧，钢框架柱的翼缘两侧各设置两个翼缘加劲肋钢板，垫板与底板用安装焊缝连接，垫板上面设有孔洞，空洞内穿设有地脚锚栓，地脚锚栓采用双螺帽，底板下面焊有承受柱脚剪力的抗剪键，抗剪键采用工字型截面，底板的下方为正方形截面的外围混凝土柱，并且外围混凝土柱的截面尺寸大于钢框架柱的截面尺寸，钢框架柱与外围混凝土柱之间浇注有无收缩细石混凝土，无收缩细石混凝土的四周均布有多条纵向钢筋，纵向钢筋用箍筋固定。本发明满足柱脚的受力情况并且稳定性好，延性好，疲劳性能好。
