Steel box tied-arch bridge steel structure construction system and method

Abstract

The invention provides a steel box tied-arch bridge steel structure construction system and method, a transportation isolation protection support is additionally arranged in the transportation process of steel beam components, and the quality and transportation safety of the steel beam components are guaranteed; according to a temporary support system, steel pipe columns are directly connected with the strip-shaped foundation embedded parts through connecting sleeves, meanwhile, the steel pipe columns are anchored with one another through unit type sliding connecting parts, an integral type steel frame is arranged at the top, and the whole temporary support system is high in building speed and good in stability; the fixed steel beam components are finely adjusted through a steel beam component splicing position adjusting device composed of an L-shaped steel plates and a jack, so that it is guaranteed that joints are tidy, the elevation is proper, the waste of raw materials is reduced, and the mounting precision and quality of the steel beam components are greatly improved. A temporary fixing system is formed between the installed steel beam components and the installed steel structure through horse plates and clamps on the two sides, and the time needed by hoisting and splicing work is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a construction system and a construction method for a steel box tie rod arch bridge steel structure. Background technique [0002] Steel box tied arch bridge has the advantages of large spanning capacity, practical durability, beautiful appearance, and less interference to traffic during construction. Compared with stone arch bridges and concrete arch bridges, steel box tied arch bridges have the lightest dead weight. And because the steel arch rib is lighter in weight, it provides convenience for the segmental assembly construction method, and gradually becomes one of the bridge types commonly used in urban bridges and scenic spots in my country. [0003] However, the structure of the steel box tied arch bridge is relatively complicated, so there are many factors that affect the stability of the structure and the dynamic performance. However, there are still many pro...
