PROTECTIVE FENCE COLUMN
PROBLEM TO BE SOLVED: To provide a protective fence column capable of efficiently absorbing collision energy when a vehicle collides, excellent in handleability in a lightweight type, and being high in permeability.SOLUTION: A protective fence column on the present invention comprises a base part fixed to an installation surface and a column body part for supporting a cross-beam on one side in the horizontal direction by standing on this base part. The column body part includes a stress dispersion part formed so as to uniformly disperse stress acting when imparting pressing force in the horizontal direction to a predetermined place of an upper part on the side for supporting the cross-beam and a stress concentration part of tilting to the opposite side of the side for supporting the cross-beam by becoming a starting point when imparting the pressing force in the horizontal direction to the predetermined place of the upper part on the side for supporting the cross-beam.
【課題】車両衝突時の衝突エネルギーを効率よく吸収でき、軽量で取り扱い性に優れ、透過性の高い防護柵支柱を提供する。【解決手段】本発明に係る防護柵支柱は、設置面に固定されるベース部と、このベース部上に立ち上がり水平方向の一側に横梁を支持する支柱本体部と、を備え、前記支柱本体部は、前記横梁を支持する側の上部の所定箇所を水平方向に押圧力を付与した際に作用する応力が均一に分散するように形成された応力分散部と、前記横梁を支持する側の前記上部の前記所定箇所を水平方向に押圧力を付与した際に起点となって前記横梁を支持する側と反対側に傾倒する応力集中部と、を備えたことを特徴とする。【選択図】図４
