Abstract

【Task】
The purpose is to make effective use of thinned timber by making blown snow fences on the shoulders of roads.
[Solution]
Forming thinned wood into a round bar shape, forming a snow plate with a gap, changing the angle of the snow plate, and adjusting the strength of the wind (snow) that blows through, eliminates the puddle that can be created on the road surface To ensure traffic safety.

Description

  The present invention relates to a blow-off type snow fence using thinned wood processed into a cylindrical shape for the entire structure.

On roads on the Sea of Japan where snowstorms are likely to occur mainly, snow blow-off type snow fences are widely installed on the shoulder side of the roads to prevent accidents from snow accumulation caused by snowstorms and driving disturbance due to poor visibility.

  Blow-off snow fences reduce the amount of snow blowing at the driver's line of sight by gathering wind (snow) downward by adjusting the angle of several snow-prevention plates installed at the top of the fence. The purpose is to eliminate the snow puddle created on the road surface by combining with the wind blowing from the space below the fence.

  In general, this snow fence is made of metal and is not only expensive to construct, but the snow protection plate is also a flat plate with no gaps. It was about.

  The inventor completed the present invention as a result of continual research considering the use of thinned wood instead of metal snow fences such as iron and aluminum. Using thinned wood, this is processed into a round columnar shape, and in particular with regard to snow-proof plates, as shown in Fig. 2, seven round bars are arranged with a slight gap between them to form a plate-like body. .

  As described above, the snow fence of the present invention is made by processing thinned wood that has been scrapped into round wood instead of the conventional metal snow fence. Especially, it is to pass a part of the wind flow by forming a plate body by combining columnar round members with a snow plate and providing a slight gap between the columnar bodies, combined with the wind blowing from the underside of the fence The snow puddle formation position can be moved downwind, and according to the results of the wind tunnel experiment, the puddle suppression range includes the width of a four-lane road. Moreover, although it is a little inferior in a 2 lane road compared with the conventional metal snow fence about the improvement effect of visibility, it is a wind tunnel experiment result superior in a 4 lane road. As a result, road safety can be ensured, reducing the number of accidents during a snowstorm and reducing vehicle traffic.

  Referring to the attached drawings, the structure of the blow-off type snow fence according to the present invention will be described. FIG. 1 is a front view of a part of the snow fence that is erected on the shoulder of the road, and symbol A indicates a snow board. In the figure, the upper A1, the middle A2, and the lower A3 are provided in three stages at the upper part between the columns (3) and (3) which are erected in a gate shape. The snow plate A will be described in detail with reference to FIG.

  FIG. 2 is formed by a round bar (1). This round bar (1) is a columnar body processed to a diameter of 5 cm, and this round bar (1) is formed in a plate-like body by arranging and fixing it in a plane with a 2 cm gap, and a snowproof plate A Form.

  Therefore, the snow fence according to the present invention is provided with three snow protection plates A made of round bars (1) each having a gap formed in the lateral direction at the upper part of the support column (3), and is formed with a space B for wind passage below this. Yes.

  For this reason, the snow fence according to the present invention allows a part of the wind to pass through by providing a gap (2) in the snow fence compared to the conventional snow fence formed by a flat plate without a gap. Combined with the wind blown from the space B, the leeward wind of the snow fence can be strengthened and the blowing effect there can be enhanced.

  FIG. 4 shows a side view of the snow fence according to the present invention, and illustrates a state diagram in which the snow guard plate A is provided at an angle and a state in which the snow guard plate A is housed other than in winter.

  As described above, the snow fence according to the present invention can effectively use thinned wood, and by forming the snow plate A having a gap (2) with a round bar, it is possible to protect the winter snow road from blowing snow. . For this reason, utility value is very large.

Claims (1)

Thinned wood is processed into a cylindrical shape to form all members, and the snow-prevention plate A is made up of several round bars (1) and a few gaps (2). (3) The wind vent part B is left below and the snow guard plate A is mounted on the upper part of the wind vent part B so that the angle can be adjusted to A1, A2, A3 and upper, middle, and lower three stages. A blow-off type snow fence using thinned wood.
