FALL PREVENTION STRUCTURE
PROBLEM TO BE SOLVED: To provide a fall prevention structure of rainwater or the like, which reduces the number of replacement operations as much as possible due to vibration caused by a traveling vehicle and deterioration of components from the environmental aspect.SOLUTION: A fall prevention upper plate 6 is fixed to a wall balustrade 4 provided on a bridge 1 by an anchor bolt 9, and a fall prevention lower plate 7 is fixed by the anchor bolt 9 to an embankment 5 provided on a bridge 2. The fall prevention upper plate 6 and the fall prevention lower plate 7 are laid so as to face each other while maintaining an appropriate gap. The fall prevention upper plate 6 and the fall prevention lower plate 7 are not affected by mutual vibrations even when the bridge 1 and the bridge 2 independently vibrate.SELECTED DRAWING: Figure 1
【課題】本発明は走行車両による振動と環境面からの構成部材の劣化を迎え、交換作業回数を極力低減する、雨水等の落下防止構造を提供することを目的とする。【解決手段】橋梁１に設けられた壁高欄４には落下防止上板６がアンカーボルト９によって固定されており、橋梁２に設けられた地覆部５には落下防止下板７がアンカーボルト９によって固定されている。落下防止上板６と落下防止下板７は適切な隙間を保ちながら対向させるように敷設される。落下防止上板６と落下防止下板７は、橋梁１と橋梁２が独立して振動した場合においても、相互からの振動の影響を受けない。【選択図】図１
