PEDESTRIAN ROAD BOUNDARY BLOCK
To provide a pedestrian road boundary block 1 that includes a foundation part 2 where an electric wire cable 4 is placed on the top and a curb part 3 that has a generally U shape with a lower part opened in the cross section placed on the top surface of the foundation part so as to cover the electric wire cable, and which has a configuration that the distance between the fastening position of an anchor bolt 5 for fixing the curb part to the foundation part and the lower end of a side wall part 3b of the curb part 3 is reduced as possible while reducing the action of the force applied to the side wall part 3b of curb part 3 on the anchor bolt 5 and reducing the width of the foundation part 2.SOLUTION: A disclosed pedestrian road boundary block 1 has a recess 3d formed by removing a part of the lower part of the side wall part of a curb part, and a through hole 5a drilled in the recess in the vertical direction. Anchor bolts 5 for fixing the curb part to the upper surface of the foundation part penetrate the through hole and are fastened to the upper surface of the foundation part.SELECTED DRAWING: Figure 1
【課題】 電線ケーブル４が上面に載置される基礎部２と電線ケーブルを覆うように基礎部の上面に配置される断面に於いて下側が開口した略Ｕ字形状の縁石部３とを含む歩車道境界ブロック１に於いて、基礎部に対して縁石部を固定するためのアンカーボルト５の締結位置と縁石部３の側壁部分３ｂの下端との間の距離をできるだけ小さくして、縁石部３の側壁部分３ｂに与えられる力のアンカーボルト５に対する作用を軽減すると共に、基礎部２の幅も小さくできる構成とすること。【解決手段】 本発明の歩車道境界ブロック１は、縁石部の側壁部の下方部分の一部に於いて肉抜きされて凹部３ｄが形成され、該凹部にて鉛直方向に貫通孔５ａが穿たれ、該貫通孔を基礎部の上面に縁石部を固定するためのアンカーボルト５が貫通して基礎部の上面に締結される。【選択図】 図１
