Combined light swivel bridge structure and construction method thereof
The invention relates to a combined light swivel bridge structure and a construction method thereof. The bridge structure comprises bridge piers, a main beam and a bridge deck slab, the main beam is arranged on the bridge piers, the bridge structure further comprises swivel spherical hinge assemblies arranged on the bridge piers, the main beam is a steel truss beam, and the steel truss beam comprises a plurality of truss units arranged in the transverse bridge direction; each truss unit comprises an upper chord member, a lower chord member and a plurality of web members located between the upper chord member and the lower chord member, each upper chord member is connected with the bridge deck slab, and each lower chord member is supported on the bridge pier. The self-weight and the vehicle load are transmitted through the steel truss girder, the structural efficiency is high, the self-weight is greatly reduced compared with the self-weight of a concrete T-shaped structure and a continuous beam of the same scale, the requirement for a swivel spherical hinge assembly is reduced, different-position disassembly or maintenance is convenient, the economic benefit is remarkable, and the durability is good; the bridge deck slab and the steel truss girders can be prefabricated, the construction period can be shortened, and the construction difficulty is reduced.
本发明涉及一种组合式轻型转体桥梁结构及其施工方法；桥梁结构包括桥墩、主梁以及桥面板，所述主梁设置在桥墩上，还包括设置在桥墩上的转体球铰组件，主梁为钢桁架梁，所述钢桁架梁包括若干沿横桥向布设的桁架单元，各所述桁架单元包括上弦杆、下弦杆以及位于上弦杆和下弦杆之间的多个腹杆，各所述上弦杆均与所述桥面板连接，各所述下弦杆支承在所述桥墩上。本发明中通过钢桁架梁传递自重及车辆荷载，结构效率高，自重较同等规模混凝土T构及连续梁自重大大减轻，降低对转体球铰组件要求且方便异位拆除或维修，经济效益显著，耐久性好；桥面板和钢桁架梁均可预制，可节省工期，降低施工难度。
