IMPACT-RESISTANT BOLLARD, CORE MATERIAL FOR IMPACT-RESISTANT BOLLARD, AND UNDERGROUND BURIED STRUCTURE OF IMPACT-RESISTANT BOLLARD
To provide a bollard installed at the boundary between a roadway and a sidewalk, which is an impact-resistant bollard having strength withstanding the collision when a traveling automobile accidentally or intentionally (terrorism or the like) runs on the sidewalk or the safety area of a pedestrian and collides with a car stop, so as to protect the safety of the pedestrian from a vehicle.SOLUTION: In an impact-resistant bollard, a bollard and a support body 10 of a core material of the bollard are provided with a ground constriction 11 and an underground constriction 12, and a structurally weak part is intentionally provided to control a bending position and a deformation amount, so that energy at the time of collision is absorbed by the bollard. A buried structure is also provided in which a plurality of concrete blocks is arranged to weaken an impact applied to the ground, to prevent the bollard from falling down, and to be used even when a buried depth cannot be taken deep or when there is an obstacle around a buried place.SELECTED DRAWING: Figure 1
【課題】 車道と歩道の境界などに設置されるボラードにおいて、走行中の自動車が偶発的或いは故意（テロなど）に歩道又は歩行者の安全領域に乗り上げ、車止めに追突した場合、その衝突に耐える強度を持つ耐衝撃性ボラードとして、車両から歩行者の安全を守る。【解決手段】ボラード及びボラードの芯材の支柱本体１０に地上くびれ１１、地中くびれ１２を設け、敢えて構造的に弱い箇所を設けることで、曲がる位置と変形量をコントロールし、衝突時のエネルギーをボラードで吸収する。また、地中へかかる衝撃を弱め、ボラードの倒れ込みを防ぎ、かつ、埋設深度を深く取れない場合や埋設場所の周りに障害物がある場合でも使用可能な複数のコンクリートブロックを配列した埋設構造物を提供する。【選択図】図１
