Connecting structure and method for concrete-filled steel tubular column and steel reinforced concrete transfer beam
The invention discloses a connecting structure and method for a concrete-filled steel tubular column and a steel reinforced concrete transfer beam. The connecting structure comprises the concrete-filled steel tubular column, a lining round steel tube, the steel reinforced concrete transfer beam, a vertical steel bar, a core column joint bar, a stirrup and a tie bar. A steel pipe of the concrete-filled steel tubular column does not extend into the steel reinforced concrete beam, a lining steel pipe is arranged at the top of the steel pipe of the concrete-filled steel tubular column to improve the local pressure bearing capacity, a plurality of vertical steel bars and core column joint bars are inserted into the steel pipe of the concrete-filled steel tubular column, and the vertical steel bars and the core column joint bars extend upwards into the transfer beam. Part of the vertical steel bars and the section steel beam are welded in a slotting mode to form a first force transmission piece when being overlapped, and the other vertical steel bars and core column joint bars adopt closed stirrups and tie bars to form core columns to serve as second force transmission pieces. The vertical steel bars and the core column joint bars can effectively transmit axial force, bending moment and shearing force at the joints. The transfer beam longitudinal bars continuously and freely penetrate through the column position, effective anchoring of the transfer beam longitudinal bars and the profile steel is ensured, force transmission is good, and construction is convenient.
本发明公开一种钢管混凝土柱与型钢混凝土转换梁的连接结构及方法，所述连接结构包括钢管混凝土柱、内衬圆钢管、型钢混凝土转换梁、竖向钢棒、芯柱插筋、箍筋、拉筋。钢管混凝土柱的钢管不伸入型钢混凝土梁内，钢管混凝土柱的钢管顶部设置内衬钢管提高局部承压承载力，钢管混凝土柱的钢管内插入多根竖向钢棒和芯柱插筋，竖向钢棒和芯柱插筋向上伸入转换梁内。部分竖向钢棒与型钢梁重叠时采取开槽焊接组成第一传力件，其他竖向钢棒及芯柱插筋采用闭口箍筋和拉筋形成芯柱为第二传力件。竖向钢棒和芯柱插筋可以有效传递节点处轴力、弯矩和剪力。本发明的转换梁纵筋连续自由贯穿柱位，确保转换梁纵筋及型钢的有效锚固，传力佳且便于施工。
