Abstract

The invention discloses an assembly type combined steel bridge. The assembly type combined steel bridge comprises four bridge seats, two longitudinal beams, a bridge deck slab and more than two crossbeams, wherein the two longitudinal beams are arranged in parallel, more than two cross beams are transversely connected between the two longitudinal beams, and the cross beams are used for supportingthe longitudinal beams connected to the two ends of the cross beams and serve as bearing beams of the bridge deck slab; the bridge deck slab is arranged on the cross beam and is used for bearing a load; the bottoms of the cross beams corresponding to the four corners of the bridge deck slab are supported on the bridge abutment through bridge seats respectively.

Description

technical field [0001] The invention relates to the technical field of emergency bridge equipment, in particular to an assembled composite steel bridge. Background technique [0002] Emergency support tasks have more and more stringent requirements for emergency equipment. The existing emergency prefabricated composite steel bridges in my country mainly include "321" combat readiness steel bridges and ZB-200 prefabricated highway steel bridges. Insufficient diameter and other shortcomings need to be researched and improved. Contents of the invention [0003] In view of this, the present invention provides a prefabricated composite steel bridge, which has the advantages of small deflection and large span, and can solve the problems of large deflection and insufficient span of the prefabricated composite steel bridge in the prior art. [0004] The present invention is achieved through the following technical solutions: an assembled composite steel bridge, comprising: four br...
