Abstract

The invention relates to a large-span bridge structure which comprises a bridge body, the bridge body comprises a plurality of piers and a bridge body arranged on the piers, stand columns are arranged on the piers and located on the two sides of the bridge, and first rod bodies are arranged between the adjacent stand columns in the length direction of the bridge body; a plurality of second rod bodies are arranged on the bridge body, the second rod bodies and the first rod bodies are arranged in a one-to-one opposite mode, and a plurality of slings are arranged between the first rod bodies and the second rod bodies in the length direction of the first rod bodies. The sling is arranged on the first rod body and the second rod body in a sliding mode in the length direction of the first rod body and the second rod body, and the first rod body is provided with a first fixing piece used for fixing one end of the sling to any moved position. And a second fixing piece used for fixing the other end of the sling to any moved position is arranged on the second rod body. The lifting device has the advantage that the transmission effect of the sling when the bridge is stressed is improved.

Description

technical field [0001] The present application relates to the field of bridge construction, in particular to a large-span bridge structure and a construction method thereof. Background technique [0002] Cable-stayed bridge is an important structural form of modern long-span bridges. As a kind of stay cable system, cable-stayed bridges have greater spanning capacity than girder bridges, and are the most important bridge type of long-span bridges. [0003] The Chinese Patent Application Publication No. CN109868717A discloses a long-span bridge, including a bridge pier, a support is installed at the top of the bridge pier, a bridge span structure is installed on the surface of the support, and a bridge pier base is installed at the bottom of the bridge pier , a bridge deck is arranged on the surface of the bridge span structure, an arch structure is arranged between the bridge pier and the bridge pier, the highest point of the arch structure is connected with the bridge span s...
