CONNECTION STRUCTURE FOR STEEL GIRDER BRIDGE AND CONNECTION METHOD FOR EXISTING STEEL GIRDER BRIDGE
PROBLEM TO BE SOLVED: To provide a connection structure capable of making jointless an upper structure of a steel girder bridge comprising various main girder structures, and a connection method for an existing steel girder bridge.SOLUTION: As a connection structure for a steel girder bridge 1 in which multiple upper structures 2 and 3 comprising steel main girders 10 which are disposed at predetermined intervals in a bridge axis right-angle direction W, in a bridge axis direction L and steel cross-girders 20 disposed in the vicinity of ends of the steel main girders 10 in the bridge axis right-angle direction W, are disposed in the bridge axis direction L, in opposite portions of the upper structures 2 and 3 being adjacent in the bridge axis direction L, connection part concrete 31 provided between the steel cross-girders 20 and PC steel bars 32 connecting the steel cross-girders 20 with each other are provided. The PC steel bar 32 is disposed in an upper part of the steel main girder 10, and the connection part concrete 31 is provided at a position higher than a lower flange 11b of the steel main girder 10 by a predetermined height.SELECTED DRAWING: Figure 1
【課題】様々な主桁構造を備えた鋼桁橋梁の上部構造物を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１０と、鋼製主桁１０の端部近傍に配置された橋軸直角方向Ｗの鋼製横桁２０とを備えた上部構造物２，３を橋軸方向Ｌに複数配置した鋼桁橋梁１の連結構造として、橋軸方向Ｌに隣り合う上部構造物２，３同士の対向部分において、鋼製横桁２０同士の間に設けられた連結部コンクリート３１と、鋼製横桁２０同士を連結するＰＣ鋼棒３２とが備えられるとともに、ＰＣ鋼棒３２が鋼製主桁１０における上部に配置され、連結部コンクリート３１が、鋼製主桁１０の下フランジ１１ｂより所定高さ高い位置に設けられた。【選択図】図１
