Abstract

The invention relates to the field of bridge construction, in particular to an arch rib segment structure and an arch bridge. The arch rib segment structure comprises a steel arch box, a steel outrigger and a steel corbel. The steel outrigger extends out of the steel arch box away from the central axis of a main beam, the steel corbel extends out of the steel arch box towards the central axis of the main beam, and the steel corbel is arranged below the horizontal plane where the steel outrigger is located. A deflection angle is formed between the body axis of the steel arch box and the centralaxis of the main beam. Alignment structures spliced with other arch rib segments are arranged at the upper end and the lower end of the steel arch box respectively. Under the cooperation of the steelarch box, the steel outrigger and the steel corbel, the arch rib segment structure is stably connected with the main beam, so that the supporting effect of the arch rib is effectively exerted.

Description

【Technical field】 [0001] The invention relates to the field of bridge construction, in particular to an arch rib segment structure and an arch bridge. 【Background technique】 [0002] With the rapid development of the modern economy, the development of high-speed railways and highways has also entered a stage of rapid development. There are more and more long-span bridges, and arch bridges have the advantages of large spanning capacity, simple structure, clear force, various forms, and beautiful appearance. High-speed railways and highways are more and more widely used, especially when crossing rivers in urban areas and suburbs. [0003] In concrete arch bridges, in addition to pier columns, arch ribs are also important supporting members of the arch bridge, which are used to assist the pier columns to balance the vertical load of the main girder. However, in the existing arch ribs, the positional relationship and matching relationship of the various components used to direc...
