The invention discloses a steel-concrete composite beam which comprises a steel beam and a pier arranged at the lower end of the steel beam. The steel beams comprise a plurality of box-shaped main beams, cross beams arranged among the box-shaped main beams, and a plurality of diaphragm plates and stiffening ribs which are arranged in the cross beams and are used for supporting, and bridge decks are arranged on the upper end surfaces of the cross beams. The invention further discloses a construction method of the steel-concrete composite beam, which comprises the following steps of: S1, constructing the lower foundation, manufacturing the steel beams in a factory section by section, and pouring the bridge deck slabs of the section steel beams; s2, construction of adjacent box-shaped girders is completed, cross beams are transported to the position close to a bridge site, and the box-shaped girders are hoisted to the bridge floor in place; s3, the step S2 is repeated, the steel cross beams are installed, the box-shaped main beams are connected into a whole, and bridge deck slabs are laid; and S4, concrete of the cast-in-place part of the bridge deck slab is The construction progress is accelerated, the impact coefficient is reduced, the anti-seismic property is good, the anti-fatigue strength is high, the local compression stability is good, and the service life is long.
本申请公开了一种钢混组合梁，包括钢梁和设置于钢梁下端的桥墩；钢梁包括：数个箱形主梁、设置于箱型主梁之间的横梁、和数个设置于横梁内部的且用于支撑的横隔板及加劲肋，横梁上端面设有桥面板。本申请还公开了一种钢混组合梁的施工方法，包括以下步骤：S1、下部基础的施工，在工厂里分节段制作钢梁，浇筑分段钢梁的桥面板；S2、完成相邻箱形主梁的施工，将横梁运至桥位附近，吊装箱形主梁至桥面就位；S3、重复S2，安装钢横梁，连接箱形主梁为整体，铺设桥面板；S4、浇筑桥面板现浇部分混凝土。本申请加快了施工进度，降低冲击系数，抗震性能好，抗疲劳强度高，局部受压稳定性能良好，使用寿命长。
