Abstract

A fence with a structure in which snow is deposited before and after a fence that suppresses wind permeability blocks the driver's vision and gives the driver a sense of oppression. The number of rows of fences is usually four or more. SOLUTION: A fence formed by arranging a plurality of vertically long panels whose horizontal cross sections are curved or bent at regular intervals so that an inner surface and an outer surface alternately appear on a curved or bent surface is formed by changing the interval between the fences. The height is almost the same as that of the three rows.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow trap fence installed as a countermeasure for eliminating a traffic obstruction at the time of a snowstorm.

[0002]

2. Description of the Related Art Snow-covered fences, which are widely used, are:
It blocks snow from entering the road before it covers the road, and prevents snow from accumulating on the road.For example, a plurality of plate bodies are grounded on a support and a support at regular intervals. There are many structures that are laid sideways with an interval up and down so as to block the snowstorm.

[0003]

However, the snow trap fence with such a structure has the effect of suppressing the wind permeability and accumulating snow before and after the fence and preventing snow from accumulating on the road. It obstructs the sight of the driver and causes the landscape to be lost, giving the driver a sense of oppression. In addition, in the field, both sunlight and breeze are stopped, so there is a situation that it is necessary to set up near the occurrence of snowstorm and to dismantle it early in the spring.

[0004] In addition, it is economically preferable that such snow-covered fences can be installed in a smaller number of rows, but it is generally said that four rows are preferably installed (see the magazine "Expressway"). And Automobile, November 1986).

[0005]

SUMMARY OF THE INVENTION The present inventor has developed a plurality of vertically long panels having a curved or bent horizontal section without obstructing the driver's vision or obstructing sunlight or breeze. Was proposed in Japanese Utility Model Registration No. 1942354, in which a curved or bent inner surface and an outer surface were alternately formed at regular intervals so as to be arranged in parallel.

The present inventor has studied whether or not the above proposal can be applied to a snow-covered fence and completed the present invention.

Basically, a fence formed by arranging a plurality of vertically long panels having a curved or bent horizontal cross section at regular intervals so that an inner surface and an outer surface of a curved or bent alternately appear.
The present invention provides snow trap fences in which a plurality of snow fences are installed with the distance between the fences substantially equal to the height of the fences.

Preferably, a fence formed by arranging a plurality of vertically long panels whose horizontal cross sections are curved or bent at regular intervals so that curved or bent inner and outer surfaces appear alternately.
The present invention provides snow trap fences with three rows of fences, with the spacing between the fences substantially equal to the height of the fences.

[0009]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a plan view showing an example of a fence, and FIG.
It is the same front view.

The panel 2 is formed by bending a vertically long steel plate so that the horizontal cross section is substantially 90 degrees at the center, and a plurality of the beams are formed of bar steel so that the bent inner surface 2a and the outer surface 2b alternately appear. 3 is fixed. Fixing is not particularly limited, such as bolting or welding. The panel 2 may be arranged between two beams and fixed from both sides. The bending angle of the panel 2 does not need to be 90 degrees, may be different, may be curved, and may be determined according to the situation at each time.

In this manner, the panel 2 is fixed to the beam 3 to form the fence 1. The fence 1 is attached to the support 4 using the metal fitting 7, and is installed at the installation place via the foundation 5.

In this example, the height of the fence is 2.5 m and the width between the columns is 3 m.

The fences 1 formed in this manner are arranged in the width direction by a necessary distance in the width direction to form a row, and as shown in FIG. .
Three rows are installed at intervals of 5 m to form a snow-collecting fence against snowstorm as a whole. 6 is a fixing wire. (Action)

When the snow-covered fence is formed as described above, the following effects are produced.

In the above configuration, in particular, when the height of the fences is made substantially the same as the fence interval, the flow of the passing wind is in principle drawn in a circle with the fences in diameter, and there is a portion where the wind does not move between the fences, Snow due to snowstorm often falls before and after the fence.

Further, since the panel 2 has an angle at which the panel 2 opens alternately, the wind reversal is reduced by a synergistic effect with the reversal wind due to the reversal of the wind by the curved or bent inner surface of the open panel. Naturally adjusted as.

Since the panels are vertically long, a sun hit is obtained by the movement of the sun between the panels.

[0019]

As described above, the present invention has the following effects.

A fence formed by arranging a plurality of vertically long panels having a curved or bent horizontal cross section at regular intervals so that the inner surface and the outer surface of the curved or bent alternately appear. Since multiple units were installed at approximately the same height, the flow of the passing wind was drawn in a circle with the diameter of the fence as a rule, and there was a part where the wind did not move between the fences. drop down. Therefore, the number of rows of fences can be reduced. In particular, a three-row installation is sufficient as disclosed in claim 2.

The curved or bent inner surface and outer surface of the panel appear alternately with respect to the direction of the wind, so that the wind transmittance is naturally adjusted. Because the sunshine is not obstructed, even if the demolition work is delayed, there is little effect on crops.

Further, since the panel is formed in a vertically long shape, a driver of a car or the like is not obstructed from the outside view regardless of the height of the line of sight.
