Embodiment 1

[0032] see figure 1 with Figure 4 , a corrugated steel arch bridge, including several piers 1 arranged on the foundation, each pier 1 is provided with embedded parts, the embedded parts include embedded bolts 101 and embedded angle steel 102; fixed connection between several piers 1 Corrugated steel arch bridge assembly, the corrugated steel arch bridge assembly includes a corrugated plate arch ring 2, which is located in the center of the bridge body, and the two ends of the corrugated plate arch ring 2 are fixed between two piers 1 by embedded parts; A number of corrugated supporting longitudinal plates 3 are respectively arranged on both sides and the upper end of the circle, and the multiple groups of corrugated supporting longitudinal plates 3 are parallel to each other, and the length of the arrangement is equal to that of the bridge plate 4, and the lower ends of the multiple groups of corrugated supporting longitudinal plates 3 respectively pass through The embedded ...

Embodiment 2

[0038] The difference from Embodiment 1 is that in this embodiment, the upper end of a single corrugated plate arch ring is directly connected to the bridge plate, and several corrugated supporting longitudinal plates are respectively arranged in parallel on both sides of the corrugated plate arch ring, and are also arranged in parallel on the corrugated plate arch ring. In the void space formed by the arch ring and the bridge plate.

Embodiment 3

[0040] see Figure 7 , a corrugated steel arch bridge, including several piers 1 arranged on the foundation, each pier 1 is provided with embedded parts, the embedded parts include embedded bolts and embedded angle steel; corrugated steel is fixedly connected between several piers 1 The arch bridge combination, the corrugated steel arch bridge combination includes a plurality of corrugated plate arch rings, which are respectively a large corrugated plate arch ring 201 located in the center of the bridge body and a number of small corrugated plate arch rings arranged on the upper end surface or both sides of the large corrugated plate arch ring 201 Ring 202, in this embodiment, the small corrugated plate arch ring 202 is arranged on the upper end surface of the large corrugated plate arch ring 201, forming a structural form similar to "Zhaozhou Bridge". Several small corrugated plate arch rings 202 are arranged symmetrically; On both sides of the corrugated plate arch ring 201,...

Abstract

The invention relates to a corrugated steel arch bridge which comprises a plurality of piers arranged on a foundation, an embedded part is arranged in each pier, a corrugated steel arch bridge assembly is fixedly connected among the piers, and the corrugated steel arch bridge assembly comprises at least one corrugated plate arch ring and a plurality of corrugated supporting longitudinal plates. The corrugated supporting longitudinal plates are distributed on the two sides or the upper end of the corrugated plate arch ring, the upper portions of the corrugated plate arch ring and the corrugated supporting longitudinal plates are connected with the bridge plate formed by corrugated steel, and the upper end face of the bridge plate is filled and laid with a roadbed bridge floor. Corrugated steel plates are adopted as construction units, the corrugated plate arch rings, the corrugated supporting longitudinal plates and the corrugated steel bridge plates which can be assembled are manufactured, the supporting strength of the corrugated supporting longitudinal plates is large, and the wind resistance and the water flow resistance of a bridge body can be greatly reduced by longitudinally arranging the corrugated supporting longitudinal plates in parallel at intervals; the single corrugated plate arch ring or the multiple corrugated plate arch rings have the curvature so as to increase the overall flexural rigidity and endurance of the bridge, and therefore the bridge body has the good pressure bearing performance and the large span.

Description

technical field [0001] The invention relates to an arch bridge structure, in particular to a corrugated steel arch bridge. Background technique [0002] An arch bridge refers to a bridge with an arch as the main load-bearing member of the structure in the vertical plane. [0003] Most of the small and medium-sized arch bridges are traditional reinforced concrete structures, which require a large amount of construction work, long design and construction time, and high maintenance costs after completion. [0004] Corrugated steel plate is a new type of product that can be widely used in various road bridges. Compared with reinforced concrete structures, it has the advantages of small interface, good flexibility, light weight, convenient production and transportation, simple construction, and short construction period. It is widely used at present. On road culverts, how to expand the application of corrugated plates to the bridge structure through the refinement and improvemen...
