FOUNDATION BLOCK FOR ELECTING POLE OF RIGID GUARD FENCE
PROBLEM TO BE SOLVED: To provide a foundation block which is safe because the shape thereof does not deformed with respect to the collision load of a vehicle even if used in a rigid guard fence vertically provided near the boundary between a roadway and a sidewalk.SOLUTION: A foundation block 1 for electing a pole 32 of a rigid guard fence 30, in which a pair of side walls 2 of an approximately square shaped plate whose lengthwise direction is along the extending direction of the road are away from and face each other respectively. A swollen part 4 across the lengthwise direction projects inward at an upper part 3 of the side wall, and the section below the swollen part is set to an inner side wall 5 widened and opened downwardly. A pole support 9 which is connected to substantially central part in the lengthwise direction between the pair of side walls to constitute a substantially I-shape in plan view projects at its upper end face 10 from the upper part, and both side end faces 11 in the lengthwise direction are gradually reduced downwardly, or massive formed by crossing between both the side walls so that a lower end face forms a void 20 at a lower level. Also, a vertical hole 13 for vertically providing the pole of the rigid guard fence is provided at least a single position on the upper end face. A void which opens to the upper part of the side wall and the side of a junction end face 6 is included also on both the side in the lengthwise direction of the pole support.SELECTED DRAWING: Figure 1
【課題】車道と歩道の境付近に立設される剛性防護柵に使用しても、車両の衝突荷重に対し変状を伴わない安全な基礎ブロックを提供する。【解決手段】剛性防護柵３０の支柱３２建て込み用の基礎ブロック１であって、長さ方向を道路の延長方向に沿わせる一対の略方形板状の側壁２は、夫々を離隔して対向せしめ、側壁の上部３で長さ方向に渡る膨出部４を内方に向けて突出するとともに、膨出部以下を下方拡開状の内側壁５とし、一対の側壁間の長さ方向略中央部に連結されて、平面視略エ字形を構成する支柱支持部９は、上端面１０が側壁の上部より上突出し、長さ方向両側の側端面１１が下方漸縮状、又、下端面が下位で空所２０を形成すべく両内側壁間に架け渡されてなる塊状であるとともに、剛性防護柵の支柱を立設する縦孔１３が少なくとも一箇所上端面に設けられ、支柱支持部の長さ方向両側にも側壁の上部及び合端面６側に開口する空所を有する。【選択図】図１
