BRIDGE FALL PREVENTION STRUCTURE
To provide a bridge fall prevention structure that can prevent a girder from falling off by using the upper surface side of the girder without deteriorating the original performance of the bridge.SOLUTION: A bridge fall prevention structure of a bridge 1 for preventing the falling off of an adjustment girder 2 whose end is installed at a girder receiving part 33 of adjacent viaducts 3, 3 includes: a beam member 4 installed on an upper surface 21 of the adjustment girder 2 and having an overhang part 42 projecting from an end edge 22 of the adjustment girder 2 in a bridge axial direction Y; and an anchor member 5 for attaching the beam member 4 to the adjustment girder 2 without restraining the expansion and contraction of the beam member 4 in the longitudinal direction. A plurality of beam members 4 is provided at intervals in the direction orthogonal to the bridge axis of the adjustment girder 2, and a plurality of anchor members 5 is provided at intervals in the longitudinal direction of the beam members 4.SELECTED DRAWING: Figure 1
【課題】橋梁の本来の性能を低下させることがないうえに、桁部の上面側を利用することで桁部の脱落を防ぐことができる橋梁の落橋防止構造を提供する。【解決手段】隣接する高架橋３，３の桁受け部３３に端部が設置された調整桁２の脱落を防ぐための橋梁１の落橋防止構造である。調整桁２の上面２１に設置されて調整桁２の橋軸方向Ｙの端縁２２から張出部４２が張り出される梁部材４と、梁部材４の長手方向の伸縮を拘束することなく調整桁２に梁部材４を取り付けるためのアンカー材５とを備えている。梁部材４は調整桁２の橋軸直交方向に間隔を置いて複数設けられるとともに、アンカー材５は梁部材４の長手方向に間隔を置いて複数設けられている。【選択図】図１
