Abstract

The invention discloses a split mounting type emergency combined bridge, and relates to the technical field of rapid construction and erection of emergency bridges; the split mounting type emergency combined bridge comprises a main beam structure, a plurality of bridge floor structures arranged above the main beam structure in parallel and bridge end transition slabs located at the two ends of the bridge floor structures, and the main beam structure comprises a main beam frame and a plurality of supporting structures. According to the invention, the section steel is spliced on site, universal profiles such as H-shaped steel, square tubes and steel plates are selected, modular design is adopted, the structure is simple, machining is convenient, and on-site welding and assembling are easy. According to the emergency combined steel bridge, on-site welding, assembling and erecting can be completed through a small amount of manpower and mechanical equipment, the personnel guarantee requirement is lowered, the installing and erecting efficiency is improved, and thus, the emergency guarantee requirement of small and medium-span bridges can be better met.

Description

technical field [0001] The invention relates to the technical field of rapid construction and erection of emergency bridges, in particular to an assembled emergency composite bridge. Background technique [0002] With the development of the country's economy and transportation, the number of small and medium-span highway bridges is increasing. Once a large-scale natural disaster occurs, it will inevitably become a major factor affecting transportation. Building temporary emergency passages and quickly erecting emergency bridges will become an important topic for research and development at present and in the future. [0003] At present, the common method is to use the reserved fabricated highway steel bridge. The prefabricated highway steel bridge is a special equipment consisting of trusses, beams and connectors. The equipment consists of many components and requires a lot of manpower for handling and installation. The installation and erection personnel must also have pro...
