EXPANSION DEVICE FOR ROAD BRIDGE
To provide an expansion device for a road bridge which has a built-in water cut-off member and can increase the durability of the water cut-off member.SOLUTION: A water cut-off member 18 comprises a gutter part 31, and a pair of fixing parts 32 each of which is integrally formed on both end parts of the gutter part 31. The gutter part 31 has flexibility in the bridge axial direction, and the fixing part 32 is harder than the gutter part 31. The water cut-off member 18 is formed in a shape close to the service condition by extrusion molding. The water cut-off member 18 is fixed by rivet fixing of the fixing part 32 to a joint 12.SELECTED DRAWING: Figure 3
【課題】止水部材内蔵型のものであって止水部材の耐久性を高くすることができる道路橋用伸縮装置を提供する。【解決手段】止水部材１８は、樋部３１と、この樋部３１の両端部にそれぞれ一体に形成された一対の固定部３２とから構成される。樋部３１は、橋軸方向に可撓性を有し、固定部３２は、樋部３１よりも硬くされている。止水部材１８は、押出成形により、使用状態に近い形状に成形される。止水部材１８は、継手１２に固定部３２をリベット止めすることで固定される。【選択図】図３
