Abstract

The embodiment of the invention discloses an assembly type corrugated steel web steel and concrete composite beam bridge and a construction method. The assembly type corrugated steel web steel and concrete composite beam bridge comprises a steel box beam, a profiled steel plate arranged at the top of the steel box beam and a bridge deck slab arranged at the top of the profiled steel plate, whereinthe steel box beam comprises a steel bottom plate, corrugated steel webs, an upper wing plate and partition plates; the corrugated steel webs are welded on the steel bottom plate and are positioned on the two sides of the steel bottom plate; and the bottom edges of the partition plates are connected to the steel bottom plate, the two sides of the partition plates are connected with the corrugatedsteel web, and the upper wing plate is arranged at the top of the corrugated steel web plate. The assembly type corrugated steel web steel and concrete composite beam bridge is convenient to assembleand construct, and can guarantee the quality of bridge prefabricated members during transportation.

Description

technical field [0001] The invention relates to the field of bridges, in particular to an assembled corrugated steel web steel-concrete composite girder bridge and a construction method. Background technique [0002] The existing steel-concrete composite beams with corrugated steel webs mainly replace the webs with corrugated steel webs on the basis of traditional concrete box girders, and retain the original reinforced concrete bottom and roof. Although the problem of web cracking is optimized, the concrete The durability of the bottom plate has not been really improved, and the self-weight of the bridge has not been reduced, and most of them are continuous structures. There are many steel-concrete connections, which are prone to fatigue damage during operation, which greatly increases maintenance costs. [0003] Therefore, it is necessary to develop an assembled corrugated steel web steel-concrete composite girder bridge and a construction method that is convenient for as...
