Abstract

The invention relates to the technical field of bridge construction and discloses a fabricated steel bridge. The fabricated steel bridge comprises a left truss, a right truss and cross beams, whereinthe cross beams are paved with bridge plates, and the bridge plates comprise first sub-plates and second sub-plates which are sequentially arranged in the length direction of the bridge; first bolts are arranged on the ends, close to the second sub-plates, of the first sub-plates, and second bolts are arranged on the ends, close to the first sub-plates, of the second sub-plates; each first sub-plate is slidingly connected with an insert in the length direction of the bridge, an insertion hole for the insert to be inserted is formed in each second sub-plate, each insert is provided with a wedgeblock positioned in the corresponding first sub-plate, the lower side of each wedge block is provided with an inclined plane inclined downward toward the direction of the corresponding insertion hole, the side, far away from the second bolt, of each wedge block abuts against the first bolt, and a nut matched with each first bolt abuts against the upper side of the corresponding wedge block. The sub-plates are connected, so that the sub-plates form a whole to prevent the sub-plates from shifting or falling off after the connection between the sub-plates and the cross beams is loosened or fallsoff, thus reducing potential safety hazards.

Description

technical field

[0001] The invention relates to the technical field of bridge construction, more specifically, it relates to an assembled steel bridge and an installation method thereof. 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.

[0003] The Chinese patent with the patent announcement number CN203625760U discloses a large-span assembled highway steel truss bridge, which includes a left truss and a right truss, a crossbeam is arranged between the left truss and the right truss, and a crossbeam is arranged between two adjacent crossbeams. Wind-resistant tie ro...
