A transverse bearing system girder bridge

Abstract

The invention discloses a bridge with a transverse bearing system. The bridge comprises a plurality of foundation piles, pier columns and a bridge deck, wherein the pier columns are arranged on the foundation piles, the bridge deck is arranged on upper sides of the pier columns, a bent cap body is arranged between the pier columns and the bridge deck in the longitudinal direction of the bridge deck, the bridge deck comprises a plurality of transverse element girders, and the transverse element girders are arranged on the bent cap body in the transverse direction of the bridge deck. The bridge with the transverse bearing system has the advantages that the bent cap body is arranged between the pier columns and the bridge deck in the longitudinal direction of the bridge deck, and is positioned at both sides of the existing obstacle, and the number of pier columns and the span diameter of the bent cap body can be freely adjusted according to the obstacle under the bridge and the weight on the bridge deck, so the clearance under the bridge or the ground is effectively saved; and meanwhile, the transverse element girders are arranged on the bent cap body in the transverse direction of the bridge deck, and the moving loads and the dead weight of the bridge decks can be directly borne by the transverse element girders, so the capability of crossing over the obstacle under the bridge or the ground is higher in comparison with the traditional transverse bent cap which firstly bears the longitudinal load of the bridge deck. The bridge with the transverse bearing system is used for the field of bridges.

Description

technical field [0001] The invention is used in the field of bridges, in particular to a girder bridge. Background technique [0002] Bridges are generally divided into five categories, namely steel frame bridges, girder bridges, arch bridges, suspension bridges and composite bridges. Among them, beam bridges are generally built in places with large spans and shallow waters. They are composed of bridge columns and bridge decks. The weight of objects is transmitted from bridge decks to bridge columns. beam or truss beam. The solid web girder has a simple structure and is more convenient to manufacture, erect and maintain, and is widely used in medium and small span bridges; the rods of the truss girder bear axial force, the material can be fully utilized, the weight is light, and the spanning capacity is large, and it is mostly used in construction Long-span bridges. [0003] At present, conventional girder bridges in my country mainly include simply supported girder bridg...

AI Technical Summary

Problems solved by technology

However, due to the large span, the structural height of the cover girder or the ground girder and the size of the bridge piers are correspondingly increased. This kind of girder bridge is not only unsightly, but also has weak spanning ability, and occupies a large clearance under the bridge or underground.
