Abstract

The invention discloses a prefabricated and assembled narrow-web combined box girder structure, which comprises a box girder body and two side longitudinal beams respectively arranged at both ends of the box girder body, and a bridge deck is arranged on the top surface of the box girder body; An anti-collision zone is provided on the side of the upper part of each side stringer close to the bridge deck, and the crash zone includes a sealing plate, an anti-collision panel and an anti-collision zone fixedly connected with the side plate of the side stringer. Collision K brace, the anti-collision panel is located on the side of the anti-collision K brace away from the side longitudinal beam, the sealing plate is located above the anti-collision K brace, the anti-collision panel and the side longitudinal beam The beams are fixedly connected to the sealing plates respectively. The prefabricated and assembled narrow-web composite box girder structure and its construction method of the present invention have simple structure and convenient assembly, and can meet the requirements of rapid construction of urban bridges.

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...
