Concrete-filled steel tube column base joint
The invention belongs to a concrete-filled steel tube column base joint in the field of civil engineering structures. The concrete-filled steel tube column base joint has the technical scheme that a concrete-filled steel tube column is positioned above a foundation; holes are formed in the center of a column base bottom plate of the concrete-filled steel tube column, so that the column base bottom plate is annular; a reinforcement cage is vertically sleeved in a root area of the concrete-filled steel tube column and comprises vertical main reinforcements and stirrups; and the vertical main reinforcements downwards penetrate through the open holes to be inserted into the foundation. The concrete-filled steel tube column base joint has the advantages that a shear key groove does not need to be reserved during foundation construction; a cup opening does not need to be reserved in a bearing platform; and a deep pit in which a steel tube column is embedded does not need to be reserved in a foundation bottom plate, so that construction is convenient and fast; and meanwhile, the cost is also reduced.
本发明属于土木工程结构领域的一种钢管混凝土柱脚节点，技术方案为：钢管混凝土柱位于基础上方，钢管混凝土柱的柱脚底板中心开孔，使柱脚底板为环形，钢筋笼竖向套在钢管混凝土柱的根部区域内，钢筋笼包括竖向主筋和箍筋；竖向主筋向下穿过开孔插入基础内。该柱脚节点无需在基础施工时预留剪力键槽，不用在承台留设杯口，也不用在基础底板上预留需埋入钢管柱的深坑，使施工便利快捷，同时也节约了成本。
