Embodiment Construction

[0020] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0021] as attached Figure 1~3 As shown, the present invention provides a kind of artificially assembled single-layer highway fast bridge, and this fast bridge comprises upper string box girder 1, end beam 2, springboard 3 and bridge deck 4; Bridge deck 4 connects two upper string box girders 1 laterally The standard section of a single-story bridge, the standard sections can be connected to each other in the longitudinal direction to form a bridge section, and the end beam 2 and the springboard 3 can be assembled at the end of the bridge section to form a single-story bridge. Bridges of different lengths can be spliced ​​to meet the requirements of external conditions such as different obstacle lengths and different traffic loads.

[0022] as attached Figure 4 As shown, the upper string box girder 1 can be used as the main longitudinal beam of the sing...

Abstract

The invention discloses an artificial assembled single-layer road express bridge and belongs to the technical field of emergency bridge structures. The express bridge comprises upper string box beams, end floor beams, a gangplank and a decking; two upper string box beams are transversely connected by the decking to form a standard section of a single layer bridge; the standard sections are longitudinally and mutually detachably connected to form a bridge main body; two ends of the bridge body are assembled with the end floor beams; the end floor beams and the gangplank are assembled to form a single-layer bridge. Single-layer bridges of different length can be assembled through adding/reducing the number of middle standard sections. The artificial assembled single-layer road express bridge of the invention can satisfy external condition requirements such as obstacles of different length and different pass load.

Description

technical field [0001] The invention relates to the technical field of emergency bridge structures, in particular to an expressway bridge manually assembled. Background technique [0002] At present, emergency bridges that can be quickly erected are mainly divided into two types: artificially assembled bridges and mechanized erected bridges. The artificially assembled bridges that have been finalized in my country mainly include "321" combat readiness steel bridges, GQL230 heavy-duty truss bridges, and ZB-200 assembled highway steel bridges. Bridges, they have played an important role in emergency relief, emergency repairs and construction. However, the above-mentioned three kinds of artificially assembled bridges are all steel structure bridges, and their individual components are heavy. It is very difficult to construct them entirely by manual assembly, and the erection speed is slow, which cannot meet the emergency erection requirements in emergency situations. Contents ...
