Abstract

The invention discloses a prefabricated assembled narrow-web combined box girder structure which comprises a box girder body and two side longitudinal beams arranged at the two ends of the box girderbody respectively, and a bridge deck slab is arranged on the top face of the box girder body. An anti-collision area is arranged on the side, close to the bridge deck slab, of the upper portion of each side longitudinal beam. The anti-collision area comprises a sealing plate, an anti-collision panel and an anti-collision K support fixedly connected with a side plate of the edge longitudinal beam,the anti-collision panel is located on the side, away from the edge longitudinal beam, of the anti-collision K support, the sealing plate is located above the anti-collision K support, and the anti-collision panel and the edge longitudinal beam are fixedly connected with the sealing plate. According to the prefabricated assembled narrow-web combined box girder structure and the construction methodthereof, the structure is simple, assembling is convenient, and the requirement for rapid construction of urban bridges can be met.

Description

technical field

[0001] The invention relates to the technical field of bridge structures, in particular to a prefabricated assembled narrow-web composite box girder structure and a construction method thereof. Background technique

[0002] Most of the anti-collision walls are concrete structures. As protective components of bridge structures, they are bulky, self-heavy, and rigid, but they are not included in the structural calculation range. Only the self-weight of the anti-collision wall is included in the structural design calculation. The contribution of anti-collision walls to bridge stiffness and mechanical performance has been neglected, and the existing anti-collision walls have complex structures and slow construction, which cannot meet the requirements of rapid construction of urban bridges. Contents of the invention

[0003] The object of the present invention is to provide a prefabricated assembled narrow-web composite box girder structure and its construction...
