To provide a bridge expansion device which solves a problem in which there is a risk that conventionally a tooth profile may cause outflow of main girders when side pressure is applied to the main girders, and proposes a concept which prevents the outflow by normal earthquake or floods striking the girders.SOLUTION: By forming a tooth profile of main girders of a conventional bridge and an expansion device part on the road side into a right-angle notch, passing through to the road side and the main girder portions by the expansion or contraction of the main girders and side pressure by floods is prevented, that is, the outflow of the bridge does not occur.SELECTED DRAWING: Figure 3
【課題】橋梁の伸縮装置に関するもの。従来に歯形形状では主桁に側圧がかかれば主桁が流出の恐れがある。従来の問題を解決しようとするものであり、通常の地震や橋桁にかかる洪水程度では流失しない構想を提案する。【解決手段】従来の橋梁の主桁と道路側の伸縮装置部の歯形形状を直角の切り込み形状にすることで、主桁の伸縮にも、洪水等による横からの圧力に対しても道路側と主桁部分に抜けることがなく、すなわち橋の流出が発生しない。【選択図】図３
