Abstract

The invention relates to a steel-concrete composite bridge and a construction method thereof, and relates to the technical field of bridge construction, the steel-concrete composite bridge is formed by splicing a plurality of steel-concrete sections, and each steel-concrete section comprises a bridge deck slab and a steel box girder; a strip-shaped opening is formed in a top plate of the steel boxgirder in the longitudinal bridge direction; the bridge deck slab comprises a deck slab body and a plurality of hollow ribs arranged below the deck slab body, the deck slab body is fixedly arranged on the upper surface of the top plate, and the hollow ribs are contained in the long-strip-shaped openings. The invention further discloses a construction method of the steel-concrete composite bridge.The steel-concrete composite bridge solves the technical problems that in the prior art, a steel-concrete composite bridge is prone to fatigue cracking, and a bridge deck is prone to damage.

Description

technical field [0001] The application relates to the technical field of bridge construction, in particular to a steel-concrete composite bridge and a construction method thereof. Background technique [0002] At present, in bridge construction, steel-concrete composite beams have been widely used because of their superiority in the overall force. Steel-concrete composite beams can effectively utilize the respective advantages of concrete and steel beams, and are easy to assemble. [0003] In related technologies, the steel structure of the steel-concrete composite beam includes a steel roof, U-ribs, and diaphragms, and the steel roof, U-ribs, and diaphragms are connected by welding, and there are many welds; the steel-concrete composite beam The concrete layer can be ordinary concrete or UHPC (Ultra-HighPerformance Concrete, ultra-high performance concrete), and the concrete layer is laid on the steel roof. [0004] However, due to the increasing traffic demand, the bridg...
