Steel beam and concrete beam connecting structure and construction technology

JIN HUAIYIN / JIANG FENGPING

The invention provides a steel beam and concrete beam connecting structure and a construction technology, and belongs to the technical field of building structures. The structure comprises a reinforced concrete beam and a steel beam which are connected through an annular rectangular steel pipe hoop, the annular rectangular steel pipe hoop comprises first Z-shaped profile steel and second Z-shaped profile steel which are arranged on the outer side of the reinforced concrete beam in a wrapping mode, and the two ends, making contact with each other, of the first Z-shaped profile steel and the second Z-shaped profile steel are fixedly connected through a plurality of fixing bolts. An H-shaped steel beam corbel is arranged on the surface of one side of the second Z-shaped section steel and corresponds to the steel beam, the steel beam is connected with flanges on the two sides of the H-shaped steel beam corbel in a welded mode, and the steel beam is connected with a middle web of the H-shaped steel beam corbel through a connecting auxiliary plate. According to the connecting structure and the connecting process of the node connecting steel member, the integrity and the rigidity of the node are guaranteed, the stress requirement of the rigid node is met, and the anti-seismic property of the node is effectively improved.

本发明提供一种钢梁与混凝土梁连接结构及施工工艺，属于建筑结构技术领域。本发明包括通过环向矩形钢管箍相连接的钢筋混凝土梁和钢梁，环向矩形钢管箍包括包覆设置在钢筋混凝土梁外侧的第一Z形型钢和第二Z形型钢，所述第一Z形型钢和第二Z形型钢相接触的两端通过若干个固定螺栓固定连接，第二Z形型钢一侧表面对应钢梁设置H型钢梁牛腿，钢梁与H型钢梁牛腿的两侧翼缘焊接连接，钢梁与H型钢梁牛腿的中间腹板通过连接副板相连接，本发明提高了连接节点的抗剪性能，节点连接钢构件的连接构造及连接工艺保证了节点的整体性及刚度，满足了刚性节点的受力需要并有效提高了节点的抗震性能。
