PROBLEM TO BE SOLVED: To reduce cost while surely preventing corrosion of a joint member 14.SOLUTION: An expansion device 10 for a road bridge comprises a pair of joint members 14, a water cutoff member 16 and a rubber layer 18. An upper plate part 20 and a side plate part 22 of the joint members 14 are integrally formed of a steel material. The water cutoff member 16 is to prevent a downward flow of rainwater of intruding from a clearance S such as rainfall time, and is arranged under the joint members 14. In the water cutoff member 16, a pair of base parts 1602 are positioned on both ends in the width W direction of the water cutoff member 16, and are respectively installed on an inner surface 2202 of the corresponding side plate part 22 by vulcanization-adhesion. The rubber layer 18 covers the whole area of the inner surface 2202 of the side plate part 22 exposed from the water cutoff member 16, the whole area of an undersurface 2004 of the upper plate part 20, the whole area of a tip surface 2006 of the upper plate part 20 and the whole area of an upper surface 2002 of the upper plate part 20.SELECTED DRAWING: Figure 3
【課題】継手部材１４の腐食を確実に防止しつつコスト低減を図る。【解決手段】道路橋用伸縮装置１０は、一対の継手部材１４と止水部材１６とゴム層１８を備えている。継手部材１４の上板部２０と側板部２２は鋼材により一体的に形成されている。止水部材１６は、降雨時などに隙間Ｓから侵入する雨水の下方への流下を防止するものであり、継手部材１４の下方に配置されている。止水部材１６は、一対の基部１６０２が、止水部材１６の幅Ｗ方向の両端に位置し、対応する側板部２２の内面２２０２にそれぞれ加硫接着により取着されている。ゴム層１８は、止水部材１６から露出する側板部２２の内面２２０２の全域、上板部２０の下面２００４の全域、上板部２０の先端面２００６の全域、上板部２０の上面２００２の全域を被覆するものである。【選択図】図３
