Steel-structure bridge

Abstract

The invention relates to the field of bridges, in particular to a steel-structure bridge, which comprises a foundation, folding bridge supporting structures, a bridge structure, a climbing structure and a buffer traction structure, wherein the number of the folding bridge supporting structures is multiple, the plurality of folding bridge supporting structures are arranged uniformly, and the bottoms of the plurality of folding bridge supporting structures are mounted at the top of the foundation; the folding bridge supporting structure comprises two first long pipes, two second long pipes, twothird long pipes, a cross beam, two bottom pipes and locking bolts, wherein the two first long pipes, the two second long pipes, the two third long pipes and the two bottom pipes are vertically arranged, and the adjacent side walls of the top ends of the two first long pipes, the two second long pipes, the two third long pipes and the two bottom pipes are connected through the cross beam. The steel-structure bridge has the advantages that the first long pipes retract into the second long pipes, the second long pipes retract into the third long pipes, and the third long pipes retract into the bottom pipes, so that the overall length can be shortened after folding, and the transportation, hoisting, loading and unloading processes are facilitated.

Description

technical field [0001] The invention relates to the field of bridges, in particular to a steel structure bridge. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. [0003] A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles. The substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment, and the auxiliary structures refer to the bridge head board, conical slope protection, revetment, diversion en...

Problems solved by technology

[0003] A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles. The substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment, and the auxiliary structures refer to the bridge head board, conical slope protection, revetment, diversion engineering, etc. At present, the steel columns on the steel structure bridge are erected, and the height of the installation is high. , during the transportation process, the steel column needs to be placed upside down. Due to the high height, the transportation occupies a large space and is not convenient for transportation.
