Abstract

The invention discloses a steel-Concrete composite bridge structure and composite bridge deck. This steel-concrete composite bridge structure comprises a composite bridge deck and a supporting beam structure supporting the connecting bridge deck. The composite bridge deck comprises a corrugated steel top plate, a reinforcing bar structure arranged on the upper part of the corrugated steel top plate and a concrete structure poured on the corrugated steel top plate and the reinforcing bar structure and connected with the corrugated steel top plate through a connecting piece. The concrete composite bridge deck comprises a corrugated steel top plate, a reinforcing bar structure arranged on the corrugated steel top plate and the corrugated steel top plate. limit bending resistance is obviouslyimproved, the cost is reduced and the dead weight is reduced at the same time.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a steel-concrete composite bridge structure and a composite bridge deck. Background technique [0002] In the existing bridge structure, the traditional orthotropic steel deck mainly includes the roof, longitudinal ribs, and transverse diaphragms. The traditional orthotropic steel deck is prone to problems such as insufficient local stiffness, prominent fatigue, and easy damage to the pavement. . Based on the above considerations, in the prior art, a concrete structure layer is set on the traditional orthotropic steel bridge deck, and the two are connected by connectors to achieve the effect of joint force, so that the key fatigue vulnerable parts can be effectively reduced by increasing the stiffness of the bridge deck The degree of stress concentration can be improved, so as to improve the fatigue cracking of orthotropic steel bridge deck and the vulnerability of b...
