Problems solved by technology

[0002] For general steel structure bridge slabs, most of the horizontal structures have large deflection, and the strength of the existing connection structure cannot meet the actual needs of the project. The upper part of the bridge deck is the pavement, which often works under the state of dynamic deflection, which will lead to the failure of the pavement. Severe splintering, in addition, the horizontal structure is not conducive to saving material

Embodiment Construction

[0019] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.

[0020] The multi-span connection structure of the present invention is installed between adjacent bridge slabs of the multi-span pipeline, and the multi-span pipeline is formed by juxtaposing two or more bridge slabs. The connection structure is used to connect adjacent bridge slabs of the pipeline, and the adjacent bridge slabs belong to different pipeline compartments. In traditional multi-span structures, when the bridge slab is arched, the force points on both sides are set on long concrete piers, such as figure 1 shown. The anchor bolts are pre-embedded on the concrete pier, and the angle steel is used as the intermediate connector, and then the angle steel and the corrugated steel plate are connected by bolts. After many years of project case summary and research by the applicant, it is found that the above-mentioned prior art has the ...

Abstract

The invention discloses a combined multi-span bridge plate connecting structure. Bridge plates with two or more spans are arranged side by side in the horizontal direction, the bridge plates are arched corrugated plates, the structure further comprises longitudinal beams arranged between arch feet of the adjacent bridge plates, each longitudinal beam comprises a beam crown and a base arranged below the beam crown, the vertical section of each beam crown is in a groove shape, an outward opening is formed in the top of each beam crown, the inner folded edges on the two sides of the opening of each beam crown are attached to and connected with arch feet of adjacent bridge plates, and shear nails are arranged in each beam crown and filled with concrete. The beam crowns are of a combined structure of steel and concrete and is high in strength, reinforcing meshes and shear nails are arranged in the beam crowns, and the strength and structural stability of the beam crowns are further improved; when the arched corrugated plates are stressed, the horizontal force generated by the arched corrugated plates extrudes the concrete in the beam crowns, so that the internal stress bearing capacityof the concrete in all directions is improved.

Description

technical field [0001] The invention relates to a connection structure, in particular to a combined multi-span bridge plate connection structure. Background technique [0002] For general steel structure bridge slabs, most of the horizontal structures have large deflection, and the strength of the existing connection structure cannot meet the actual needs of the project. The upper part of the bridge deck is the pavement, which often works under the state of dynamic deflection, which will lead to the failure of the pavement. Fragmentation is severe, and in addition, the horizontal structure is not conducive to saving material. Contents of the invention [0003] Purpose of the invention: The present invention aims to provide a bridge-slab connection structure with high strength, low cost and convenient installation. [0004] Technical solution: In the combined multi-span bridge slab connection structure of the present invention, the bridge slabs with two or more spans are a...
