GUARD FENCE SUPPORT POST
To provide a guard fence support post which brings about excellent effects in the sense that even if it is used in the work of replacing the deck of a road on a bridge, there is no need for temporary re-installation, and even if it is used on roads with narrow median strips, it can be used for both guard fences installed on both sides.SOLUTION: In a guard fence support post 1 which includes a base plate 11 fixed to a slab 7 as a foundation and a pipe body 21 erected from the base plate 11, and can absorb through plastic deformation of the tube body 21 the impact load applied to the tube body 21, the tube body 21 is square shaped, and a pair of notch holes 31A, 31B are respectively provided at the four corners 21e of the lower end 21a of the rectangular tube body 21 with intervals 33 in the tube axis direction.SELECTED DRAWING: Figure 2
【課題】橋梁上の道路の床版取替え工事に用いても、仮設し直しの手間を要さず、中央分離帯が狭い道路等に用いても、両側に設ける防護柵の両方に対して、その優れた効果を発揮させることができる、防護柵用支柱を提供する。【解決手段】基礎としての床版7に固定されるベースプレート11と、ベースプレート11から立設された管体21とを備え、管体21に負荷される衝撃荷重を管体21の塑性変形により吸収可能な防護柵用支柱1であって、管体21は、角形であり、この角形の管体21の下端部21aの四隅の角部21eに、その管軸方向に間隔33を空けて形成された一組の切欠孔31A,31Bをそれぞれ備えている。【選択図】図2
