The invention provides a
bridge deck capable of being used for a steel-UHPC (
Ultra High Performance Concrete) composite
beam bridge, a steel channel beam, a
beam bridge and a construction method thereof the
bridge deck, and aims to solve technical problems that the steel-UHPC composite
beam bridge is
overweight in bridge structure, not high in span, poor in
crack resistance of a concrete
bridge deck and the like. The bridge
deck is a one-way rib UHPC bridge
deck and comprises a thin bridge
deck body and a plurality of UHPC transverse ribs integrally formed at the bottom of the bridge deck body, and the one-way rib UHPC bridge deck is not provided with longitudinal ribs; the steel channel beam is a U-shaped channel beam and comprises a bottom plate, webs connected to the two sides of the bottom plate and
flange plates connected to the top faces of the webs, and longitudinal bridge direction stiffening ribs are arranged on the bottom plate and the webs; the beam bridge comprises a plurality of full-hole simply-supported beams which are mutually connected in the longitudinal direction of a bridge, and each full-hole simply-supported beam comprises a one-way rib UHPC bridge deck slab, a steel tank beam and a shear key. The beam bridge adopts a mode that in-
plant construction is firstly performed to form a full-hole simply supported beam, and then on-site hoisting is performed. The bridge deck is advantaged in that the
self weight of the bridge structure is reduced, stress is reasonable,
pier top
crack resistance is high, joints are few, construction is easy and convenient, and durability is excellent.
