Abstract

The invention relates to an assembly type steel bridge and a building method of the steel bridge. The assembly type steel bridge comprises supporting frames, a bridge deck slab, an H-shaped beam, bridge deck slab connecting parts and H-shaped beam locking mechanisms. The H-shaped beam is arranged on the supporting frames. The extension direction of the H-shaped beam is perpendicular to the extension direction of the supporting frames. The supporting frames support the H-shaped beam. The bridge deck slab is laid on the H-shaped beam. The supporting frames and the H-shaped beam are fixedly installed through the H-shaped beam locking mechanisms. The H-shaped beam and the bridge deck slab are fixedly installed through the bridge deck slab connecting parts. According to the steel bridge, the number of components is small, the structure is light and simple, erecting is fast, assembling, disassembling and replacing are convenient, the components can be purchased in batches according to the requirement of the construction progress in the construction and installation process, and installing and erecting are carried out while materials enter the site; in the disassembling process, disassembling is carried out while the materials are moved out of the site in batches, and the problem that due to stacking of the materials, construction of other special projects is influenced can be effectively solved.

Description

technical field [0001] The invention relates to an assembled steel bridge and a construction method thereof, belonging to the technical field of bridge construction. Background technique [0002] Prefabricated steel bridges are usually suitable for emergency emergencies. Therefore, the bridge structure is required to be light, strong in mobility, convenient in transportation, fast in assembly, and strong in adaptability. It can be widely used in wartime repairs and peacetime flood control and disaster relief. Rapid construction of road bridges and temporary road bridges, as well as auxiliary equipment for road construction. Prefabricated steel bridges are mainly used in bridge construction, and 80% of them are top-supporting bridges, but the existing installation structure cannot meet the requirements of construction; the invention adopts the design of the bottom-supporting structure, which changes the usual construction bridge to the upper-supporting The integrated design ...
