FILLING STRUCTURE FOR ROAD BRIDGE EXPANSION DEVICE
To provide a filling structure for road bridge expansion device having excellent durability, in which the durability of a filling component is improved by reducing the load applied to the filling component.SOLUTION: In a state where a gap S is smallest, a vertical displacement member 16A is at the most downwardly displaced position and a support member 40 is accordingly also at the most downwardly displaced position. The support member 40 is located at a position downwardly separated from a filling component 32 located between mutually facing side portions of the V-shaped convex part (between the side end faces). In a state where the gap S is largest, the vertical displacement member 16A is at the most upwardly displaced position and the support member 40 is accordingly also at the most upwardly displaced position. The support member 40 lifts the filling component 32 up to a position where the upper end of the filling component 32 is located slightly below a top face 2002 of a faceplate 20.SELECTED DRAWING: Figure 7
【課題】間詰め部材が受ける負荷を軽減することで間詰め部材の耐久性を向上させ、耐久性に優れる道路橋伸縮装置用間詰め構造を提供する。【解決手段】隙間Ｓが最も小さくなった状態では、上下変位部１６Ａは最も下方に変位した位置となり、これに伴い支持部材４０も最も下方に変位した位置となり、支持部材４０は、Ｖ字状凸部の互いに対向する側部間（側部先端面間）に位置する間詰め部材３２の箇所の下方に離れた箇所に位置する。隙間Ｓが最も大きくなった状態では、上下変位部１６Ａは最も上方に変位した位置となり、これに伴い支持部材４０も最も上方に変位した位置となり、支持部材４０は、間詰め部材３２の上端が表面板２０の上面２００２よりも僅か下方に位置する箇所まで間詰め部材３２を持ち上げる。【選択図】図７
