Description

本発明は、冬期間における道路等への積雪量を軽減し、かつ視程障害を緩和するため、道路脇に設置する防雪柵に関する。   The present invention relates to a snow fence installed on the side of a road in order to reduce the amount of snow on a road during winter and to reduce visibility obstacles.

従来、防雪板の上部を整流部とし、防雪板の整流部より下方を吹き止め部とした防雪柵は知られている。   2. Description of the Related Art Conventionally, a snow fence is known in which an upper portion of a snow protection plate is a rectifying portion, and a lower portion than the rectification portion of the snow protection plate is a blowing prevention portion.

例えば、実開昭５９−６１３１２号公報の第５図には、防雪柵上部の一枚の整流板を路面上に向けて上向き傾斜とし、整流板より下方に適当な通風率を有する防雪板を配置した防雪柵が示されている。   For example, in FIG. 5 of Japanese Utility Model Laid-Open No. 59-61312, a snow proof plate having an appropriate ventilation rate is provided below the rectifying plate with a single rectifying plate on the top of the snow proof fence inclined upward on the road surface. The arranged snow fence is shown.

この防雪柵では、整流板により風下側において風雪の巻き込みおよび落下が抑止され、風雪は上空で遠方に飛散され、道路への積雪を最小限に押さえることができる、という効果が示されている。   In this snow fence, it is shown that the baffle is prevented from being caught and dropped on the leeward side by the baffle plate, and the wind and snow are scattered far away in the sky, so that snow accumulation on the road can be minimized.

また、特開２００２−２２７１３８号公報には、風流入側の一端部が曲面に形成されている風向変換板を、断面形状の厚さが変化しない薄鋼板としたもの、断面形状が中空の翼型としたものが示されている。
実開昭５９−６１３１２号公報 特開２００２−２２７１３８号公報 Japanese Patent Application Laid-Open No. 2002-227138 discloses that a wind direction conversion plate having a curved end portion on the wind inflow side is a thin steel plate whose cross-sectional shape does not change, and a blade having a hollow cross-sectional shape. The type is shown.
Japanese Utility Model Publication No.59-61312 JP 2002-227138 A

前記の実開昭５９−６１３１２号公報における技術では、防雪柵の上部に一枚の整流板を路面上に向けて上向き傾斜としたものであるが、整流板より風下側の風雪の巻き込みは防止できるが、防雪柵の風上側に形成する吹き溜まりについては考慮されていない。   In the technique disclosed in Japanese Utility Model Publication No. 59-61312, a single rectifying plate is inclined upward on the road surface at the top of the snow fence, but entanglement of wind and snow on the leeward side of the rectifying plate is prevented. Yes, but it does not take into account the puddle that forms on the windward side of the snow fence.

一般的な吹き止め柵は、現地の気象条件を考慮して、冬季間のうちに防雪柵の風上側に形成する吹き溜まりが柵を越えないよう柵高を設定するが、そのため柵高が５ｍ以上と非常に高くなってしまい、その設置費用がかさむという問題があった。   For general blow-off fences, considering the local weather conditions, the fence height is set so that the puddle that forms on the windward side of the snow fence does not cross the fence during the winter. There was a problem that the installation cost was increased.

柵高が低い、あるいは積雪が想定を超えた場合には、吹き溜まりが柵を越え、道路に雪が堆積し、防雪柵としての機能を失ってしまうという問題があった。   When the fence height is low or the snow cover exceeds the expected level, there is a problem that the snow pool accumulates over the fence and the function as a snow fence is lost.

そこで本発明は、防雪柵の風上に形成される吹き溜まりの成長を押さえ、比較的柵高が低くても防雪柵としての機能を失ってしまうことがなく、設置費用を低減させることを目的とする。   Therefore, the present invention aims to reduce the installation cost by suppressing the growth of the puddle formed on the windward side of the snow fence and without losing the function as the snow fence even if the fence height is relatively low. To do.

請求項１の発明による防雪柵は、道路の風上側に所定間隔ごとに支柱２を立設し、支柱２間に複数枚の防雪板３を配置した防雪柵において、防雪板３の上部を整流部５とし、整流部５に路面上に向けて上向き傾斜の整流板６を設け、整流板６は上下に配置した複数枚で構成され、上下に配置した複数枚の整流板６が上方ほど路面上から遠ざかる風上側に位置するよう傾斜して配置し、防雪板３の整流部５より下方は通風を妨げる吹き止め部４としたものである。 The snow fence according to the first aspect of the present invention is a snow fence with standing pillars 2 provided at predetermined intervals on the windward side of the road, and a plurality of snow guard plates 3 arranged between the pillars 2, and the upper portion of the snow guard plate 3 is rectified. The rectifying unit 5 is provided with a rectifying plate 6 inclined upward toward the road surface. The rectifying plate 6 is composed of a plurality of plates arranged vertically, and the plurality of rectifying plates 6 arranged vertically are arranged on the road surface upward. It is arranged to be inclined so as to be located on the windward side away from the top, and below the rectifying part 5 of the snow protection plate 3 is a blow-off part 4 that prevents ventilation.

請求項２の発明による防雪柵は、整流部５の整流板６を翼型断面21，22としたものである。   The snow fence according to the invention of claim 2 is configured such that the rectifying plate 6 of the rectifying unit 5 has airfoil cross sections 21 and 22.

請求項１の発明によれば、防雪板３の上部を整流部５とし、整流部５に路面上に向けて上向き傾斜の整流板６を設け、整流板６は上下に配置した複数枚で構成され、上下に配置した複数枚の整流板６が上方ほど路面上から遠ざかる風上側に位置するよう傾斜して配置し、整流板６が防雪柵の風上側に形成する吹き溜まりに接近し、整流部５が吹き溜まりの雪を強く吹き払う作用が増すから、防雪柵の風上側に形成される吹き溜まりの成長を押さえ、比較的柵高が低くても防雪柵としての機能を長期間持続でき、設置費用を低減させることができる。 According to the invention of claim 1, the upper part of the snow protection plate 3 is the rectifying unit 5, the rectifying unit 5 is provided with the rectifying plate 6 inclined upward toward the road surface, and the rectifying plate 6 is composed of a plurality of plates arranged vertically.

Can be reduced.

請求項２の発明によれば、整流部５の整流板６を翼型断面21，22としたから、より整流部５の強く雪を吹き払う作用が増し、より防雪柵の風上側に形成する吹き溜まりが防雪柵を越えにくい。
According to the invention of claim 2 , since the rectifying plate 6 of the rectifying unit 5 has the airfoil cross sections 21 and 22, the rectifying unit 5 has a stronger effect of blowing off snow more and is formed on the windward side of the snow fence. The puddle is hard to cross the snow fence.

防雪柵の風上側に形成される吹き溜まりの成長を押さえるという目的を、防雪板３の上部を整流部５とし、整流部５に路面上に向けて上向き傾斜の整流板６を設け、整流板６は上下に配置した複数枚で構成され、上下に配置した複数枚の整流板６が上方ほど路面上から遠ざかる風上側に位置するよう傾斜して配置することにより実現した。 For the purpose of suppressing the growth of the puddle formed on the windward side of the snow fence, the upper part of the snow protection plate 3 is used as a rectification unit 5, and the rectification unit 5 is provided with a rectification plate 6 inclined upward toward the road surface. This is realized by arranging a plurality of rectifying plates 6 arranged one above the other so as to be positioned on the windward side away from the road surface as the upper side is arranged.
