Description

[0001] Grade maintainable steel box girder bridge [0002]

The present invention relates to a girder girder bridges, and more particularly, to a girder girder bridges which is provided so as to support a supporting member at an inner side portion or an outer side portion with respect to a curve radius in a curved section of a bridge, The present invention relates to a girder bridge capable of being maintained.

Generally, a bridge is a road structure that traverses a river or the like. The bridge is composed of a pile, a top plate installed on the pile head, and has a general road bridge, a bicycle bridge, a walking bridge, Consists of a number of piers, and a top plate that is placed on the piers and piers.

Such conventional bridges are generally installed parallel to the ground, but they are installed to provide a section in the form of a curved line in a plan view according to the geographical conditions such as a ramp section and a mountainside. In such a curved section, a slope is generally made to have an inclination from the outer periphery outside the center of rotation to the inner periphery inside. For example, as shown in Figs. 1 and 2, in the case of a girder bridge, the upper plate 11 supported by the girder girder 10 is installed so as to have a gradient? In the curve section. By thus forming the bridge, it is possible to prevent the phenomenon that the vehicle departs to the outside of the upper plate 11 when the vehicle runs on the curved line.

However, when a large number of vehicles travel for a long period of time at the outer portion of the upper plate 11, fatigue accumulates, and when the fatigue limit is exceeded, there is a problem that the upper plate 11 can be turned over.
