Fully-fabricated steel-concrete slab truss combined bridge and construction method thereof
The invention discloses a full-assembly type steel-concrete slab truss combined bridge and a construction method thereof, belongs to the field of bridge engineering, and solves the problems that a steel truss steel pipe wall of a traditional steel-concrete combined structure bridge is prone to buckling and complex in structure. The fabricated bridge comprises a fabricated main beam and a fabricated bridge pier, the fabricated main beam comprises a truss and a prefabricated concrete bridge deck, the fabricated bridge pier adopts a box type concrete filled steel tube bridge pier, two rectangular cavities are formed in an inner cavity of the box type concrete filled steel tube bridge pier, first strip-shaped steel plates are arranged on the peripheries of the inner walls of the cavities, and a plurality of holes are formed in the first strip-shaped steel plates; the cavity is filled with steel fiber reinforced concrete, and the box type concrete filled steel tube pier is connected with the truss. The construction method comprises the steps of installing the box-type concrete-filled steel tube pier; assembling type main beams are installed; and mounting the prefabricated concrete bridge deck slab. The assembly type main beam and the assembly type bridge piers form a pier beam rigid connection structure system, so that force transmission of the upper structure and the lower structure is smooth, and the structural integrity and the anti-seismic property are further improved.
本发明公开了一种全装配式钢‑混凝土板桁组合桥梁及其建造方法，属于桥梁工程领域，解决了传统的钢混组合结构桥梁存在的钢桁钢管壁容易产生屈曲、构造复杂的问题。本发明包括装配式主梁和装配式桥墩，装配式主梁包括桁架和预制混凝土桥面板，装配式桥墩采用箱型钢管混凝土桥墩，箱型钢管混凝土桥墩内腔设有两个矩形腔室，腔室内壁四周均设有第一条状钢板，第一条状钢板上开设有多个孔洞，腔室内填充有钢纤维混凝土，箱型钢管混凝土桥墩与桁架相连。建造方法：安装箱型钢管混凝土桥墩；安装装配式主梁；安装预制混凝土桥面板。本发明中的装配式主梁和装配式桥墩组成墩梁刚接结构体系，使得上、下部结构传力顺畅，结构整体性、抗震性能进一步提高。
