The invention relates to the technical field of railways and highway bridges, and particularly discloses a steel-concrete composite beam overcrossing a railway business line and a construction method.The steel-concrete composite beam comprises a steel box beam, steel flanges are fixedly connected to the two sides of the top end of the steel box beam, tie steel is arranged in the top ends of the steel flanges, and stiffening shins are arranged on the side faces of the tie steel; one end of the steel box girder is fixedly connected with the combination end, the bottom layer pulling buckle is fixedly connected into the combination end, the upper layer pulling buckle is fixedly connected into the connection end, the bottom layer pulling buckle corresponds to the upper layer pulling buckle, the steel frame cage is arranged on the inner side of the separation support, the steel frame cage is arranged in the combination end, and the overall strength and stability are improved. The structure is simple and practical, construction is convenient, the combination section can more evenly and smoothly transmit axial force, shearing force, bending moment and deformation generated by various loads, and good fatigue resistance and durability are achieved.
本发明涉及铁路、公路桥梁技术领域，更具体的公开了一种上跨铁路营业线的钢混结合梁及施工方法，包括钢箱梁，钢箱梁顶端的两侧均固定连接设有钢翼缘，钢翼缘顶端的内部设有拉结钢，拉结钢的侧面设有加劲胫，钢箱梁的一端固定连接设有结合端，结合端的内部固定连接设有底层拉结扣，连接端的内部固定连接设有上层拉结扣，底层拉结扣与上层拉结扣相互对应，分隔支撑的内侧设有钢架笼，钢架笼设在结合端内，整体强度及稳定性得到提高，结构简单实用，施工方便，使结合段能更加均匀顺畅地传递各种荷载产生的轴力、剪力、弯矩和变形，具有良好的抗疲劳性和耐久性。
