Abstract
【解決手段】間隔を置いて支柱2,3…3,2を立設すると共に、これら支柱2,3…3,2間に防護面13を設けた防護体において、上部の前後に、雪が滑り落ちる傾斜面22Aを有する覆い体21を設ける。覆い体21の傾斜面22Aにより雪が滑り落ち、雪庇が大型化することが防止され、雪庇による荷重を削減できる。また、雪庇が大型化して道路などに落下することを防止できる。さらに、前後の傾斜面22A,22Aのなす角度は34〜40度が好ましく、雪により防護柵に加わる沈降力を軽減できる。また、隣合う支柱2,3…3,2の上部間に角型鋼材23を配置し、この角型鋼材23に覆い体21を外装したから、角型鋼材23により覆い体21の強度を向上することができる。
