Description
(1)支柱の中間部に配設する中間部防雪板群は空隙率が約30〜40%の多数枚の有孔板で構成し、上部側に配設する上部防雪板群は空隙率が約70〜90%の1枚乃至複数枚の網状パネルで構成することにより、防雪柵に掛る風荷重を可及的に小さくすると共に重心を低くしたから、柱脚体を大型にすることなく柵高を防風・防雪効果の高い約7mの高さにまで高くすることができる。
(2)下部防雪板群、中間部防雪板群及び上部防雪板群は、支柱の高さの約3分の1ずつの縦幅に設定したことにより、防雪柵に掛る風荷重は上側に対して下側が大きくて重心位置も下側になり、柱脚体に掛る転倒モーメントも従来技術の場合と殆ど変わらないことから、支柱高さを約7mに設定しても柱脚体は従来技術のものと同程度の大きさで足りる。
(3)支柱の上部側に配設する防雪板は、空隙率が約70〜90%の網状パネルで構成してあり、網状パネルを通して景観を目視できるから運転者に与える圧迫感を最小限にすることができるし、景観阻害の問題も解決できる。

Claims (3)
- 道路に沿って所定の間隔毎に地盤に埋設する柱脚体と、該各柱脚体に立設する支柱と、該支柱間に架設することにより高さ方向に配設した複数枚の防雪板とからなる防雪柵において、前記支柱間の下部側に設ける下部防雪板群は複数枚の無孔板により構成し、中間に設ける中間部防雪板群は空隙率が約30〜40%の複数枚の有孔板により構成し、上側に設ける上部防雪板群は空隙率が約70〜90%の1枚乃至複数枚の網状パネルにより構成してあることを特徴とする吹き止め式防雪柵。
- 前記支柱は直線状の鋼材からなることを特徴とする請求項1記載の吹き止め式防雪柵。
- 前記下部防雪板群、中間部防雪板群及び上部防雪板群は、前記支柱の高さの約3分の1ずつの縦幅に設定してあることを特徴とする請求項1記載の吹き止め式防雪柵。
