CONNECTION STRUCTURE OF STEEL GIRDER BRIDGE AND CONNECTION METHOD OF EXISTING STEEL GIRDER BRIDGE
PROBLEM TO BE SOLVED: To provide a connection structure capable of integrally connecting steel girders in a superstructure of a steel girder bridge each having different configurations in a joint-less manner, and a connection method of existing steel girder bridges.SOLUTION: The connection structure of a steel girder bridge 1 which includes superstructures 2a and 2b having a plurality of steel girders 20 and 30 which are disposed along a bridge axial direction L at predetermined intervals in a direction W perpendicular to the axis. A connection cross beam 60, which is disposed along a direction W perpendicular to the bridge axis and which is disposed between the superstructures 2a and 2b neighboring each other along a bridge axial direction L, is connected to the steel girders 20 and 30.SELECTED DRAWING: Figure 1
【課題】鋼桁橋梁の上部構造物において、構成が異なる鋼製主桁同士を連結して一体化し、ジョイントレス化できる連結構造及び既設鋼桁橋梁における連結工法を提供することを目的とする。【解決手段】橋軸直角方向Ｗに所定間隔を隔てて配置された橋軸方向Ｌの鋼製主桁２０，３０を備えた上部構造物２ａ，２ｂを橋軸方向Ｌに沿って複数配置した鋼桁橋梁１の連結構造であって、橋軸方向Ｌに沿って隣り合う上部構造物２ａ，２ｂ同士の間に配置された橋軸直角方向Ｗに沿って配置された連結横桁６０に、鋼製主桁２０，３０を連結した。【選択図】図１
