Problems solved by technology

Moreover, the larger the span, the more obvious the advantages. However, due to the controlling influence of the buckling stability of the steel web, the span of the corrugated steel web-concrete composite box girder bridge is greatly limited. At present, the maximum span is only 164m, while the concrete The maximum span of the web box girder bridge has exceeded 300 meters
The span of corrugated steel web-concrete composite box girder bridge is extremely limited, and its advantages cannot be fully utilized

Embodiment Construction

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] refer to figure 1 , the composite corrugated steel web box girder of the present invention is made of top plate 10, bottom plate 11, left side corrugated steel web 12, right side corrugated steel web 13, referring to figure 2 , the left corrugated steel web 12 and the right corrugated steel web 13 include an outer corrugated steel plate 131 and an inner corrugated steel plate 132, and the outer corrugated steel plate 131 and the inner corrugated steel plate 132 are connected as one by a connector 14 to form a composite corrugated steel plate web.

[0015] Without increasing the total thickness of the web, the composite corrugated steel web can greatly improve the stiffness of the steel web in both directions, greatly improve the buckling stability of the web, and thus greatly improve the composite corrugated steel web-concrete The limit span o...

Abstract

The invention discloses a composite corrugated steel web box girder to greatly increase the limit span of a corrugated steel web and bring the superiority of a steel-concrete composite box girder bridge into full play. The composite corrugated steel web box girder is composed of a top plate, a base plate, a left corrugated steel web and a right corrugated steel web, wherein the left corrugated steel web and the right corrugated steel web each comprise outer corrugated sheet steel and inner corrugated sheet steel, and the outer corrugated sheet steel and the inner corrugated sheet steel are connected into a whole through connectors to form the composite corrugated steel webs.

Description

technical field [0001] The invention relates to bridges, in particular to a composite corrugated steel web box girder applied to long-span continuous rigid frame (beam) box girder bridges. Background technique [0002] The corrugated steel web-concrete composite box girder bridge has better economic advantages, shorter construction period and convenient construction than the concrete web box girder bridge. Moreover, the larger the span, the more obvious the advantages. However, due to the controlling influence of the buckling stability of the steel web, the span of the corrugated steel web-concrete composite box girder bridge is greatly limited. At present, the maximum span is only 164m, while the concrete The maximum span of the web box girder bridge has exceeded 300 meters. The span of corrugated steel web-concrete composite box girder bridge is extremely limited, and its superiority cannot be fully utilized. [0003] The overall mechanical characteristics of corrugated ...
