INSTALLATION STRUCTURE, BASE MEMBER, AND INSTALLATION METHOD OF BRIDGE GUARD FENCE
PROBLEM TO BE SOLVED: To provide an installation structure of a bridge guard fence that ensures sufficient strength even when a ground cover is narrow.SOLUTION: An installation structure for a bridge guard fence includes: a plurality of anchor bolts B1 fitted on a top surface of a ground cover W of a road bridge and arranged to form two or more rows in a direction of extension of the ground cover W; a base member 3 fixed to project outward in a bridge width direction from the ground cover W; a support post 1 fixed on the base member 3; and a beam fitted on the support post 1. The base member 3 includes a plurality of anchor bolt fitting holes 311 through which each of the plurality of anchor bolts B1 penetrates. An interval between the plurality of anchor bolt fitting holes 311 arranged in the direction of extension of the ground cover W is of a ratio between 0.5 and 3.0 with respect to an embedded depth of the plurality of anchor bolts B1 into the ground cover W.SELECTED DRAWING: Figure 1
【課題】幅の狭い地覆であっても十分に強度を確保できる橋梁用防護柵の設置構造を提供する。【解決手段】道路用橋梁における地覆Ｗの上面に取り付けられ、地覆Ｗの延長方向に向かって２列以上となるように配置される複数のアンカーボルトＢ１と、地覆Ｗから橋梁幅方向外側に張り出すように固定されるベース部材３と、前記ベース部材３上に固定される支柱１と、前記支柱１に取り付けられる横梁と、を備え、前記ベース部材３は、前記複数のアンカーボルトＢ１の各々が貫通する複数アンカーボルト取付孔３１１を備え、前記複数のアンカーボルト取付孔３１１は、地覆Ｗの延長方向における配置の間隔につき、前記複数のアンカーボルトＢ１の地覆Ｗへの埋め込み深さを基準とした比率で０．５〜３．０となる間隔で配置された橋梁用防護柵の設置構造である。【選択図】図１
