Large-span prefabricated bridge structure
The invention discloses a large-span prefabricated bridge structure. The large-span prefabricated bridge structure comprises a beam body, wherein the beam body is sequentially provided with a beam rib area and a beam wing plate area which are connected in the longitudinal direction of the beam body. Bridge floor cast-in-place layers are arranged on the tops of the beam rib area and the beam wing plate area. The beam rib area is provided with a plurality of first cross-joint force-bearing assemblies which are arranged at intervals and a plurality of first buried assemblies arranged at intervals. The first cross-joint force-bearing assemblies and the first embedded assemblies are welded and connected. The beam wing plate area is provided with a plurality of second cross-joint force-bearing assemblies which are arranged at intervals and a plurality of second buried assemblies arranged at intervals. The second cross-joint force-bearing assemblies and the second buried assemblies are arranged in the transverse direction of a large-span prefabricated bridge. The second cross-joint force-bearing assemblies and the second buried assemblies are welded and connected. By means of the large-span prefabricated bridge structure, the tensile strength of breaking joint positions is improved, and therefore cracks at end joints are reduced, the influences of water seepage caused after a bridge floor cracks on the beam body are reduced, and the durability of the bridge is improved.
