PROBLEM TO BE SOLVED: To provide a guard fence for a bridge properly plastically deformable to an impact load by a collision of a vehicle.SOLUTION: A front support part 4F and a rear support part 4R for constituting a support member 4 are integrated into a base member 2, and the front support part 4F and the rear support part 4R are integrated via a center pillar 3, and a column body 5 is integrated into the center pillar 3, and is integrated into the front support part 4F, and a fixing end to the base member 2 in the front support part 4F and the rear support part 4R is further positionally dislocated forward to the center pillar 3, and buckling strength of the column body 5 is set higher than buckling strength of the support member 4.SELECTED DRAWING: Figure 4
【課題】 車両の衝突などによる衝撃荷重に対して適度に塑性変形させ得る橋梁用防護柵の提供を課題とする。【解決手段】 支持部材４を構成する前方支持部４Ｆ、および後方支持部４Ｒがベース部材２に一体化され、前方支持部４Ｆ、および後方支持部４Ｒは中柱３を介して一体化され、支柱本体５は中柱３に一体化されるとともに、前方支持部４Ｆに一体化され、さらに、前方支持部４Ｆ、後方支持部４Ｒにおけるベース部材２への固定端は、中柱３に対して前方に位置ずれしており、支柱本体５の座屈強度は、支持部材４の座屈強度に比べて高く設定されている。【選択図】 図４
