BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow retaining structure on a side of a passage and a structure for preventing rolling-up. More specifically, the present invention relates to a snowy approach to a place where a high step is formed on the side of a passage such as an approach in a residential area. The present invention relates to a fastening and rolling prevention structure.

As is well known, in residential area planning and the like,
An approach that is a mounting passage from a residential road to the entrance of each house or a kitchen may be installed, but a step higher than the passage may be formed beside the passage such as the approach. is there. When a high step portion is formed on the side of the passage as described above, in a snowy area, a snow layer formed on the step portion depends on the environment such as temperature, humidity, solar radiation, and wind speed. Various phenomena occur with respect to. As an example, a phenomenon referred to as so-called hang-over may occur. As shown in FIG. 6, the wrap-around is caused by the snow layer C formed on the upper surface of the step B which is damaged on the side of the passage A. Step B
This is a phenomenon in which the paper is bent so as to be caught inside with the icicles C1 generated at all ends of the side edges B1 without cutting and falling. Further, as another example, the snow layer formed on the upper surface of the step portion may rise extremely high, and a phenomenon that a large amount of snow falls at once by the influence of wind or the like may occur.

[0003]

However, in the case where the steps on the side of the passage are rolled up or a large amount of snow falls from the steps as described above, the pedestrians who are moving up and down the passage are required. This will cause adverse effects such as underlaying. For this reason, it is indispensable to prevent the occurrence of the rolling and the large amount of snowfall in order to avoid snow damage in a snowy area, but it is troublesome and necessary to avoid such a situation. There is a problem that a complicated snow removal operation is required, and a large labor and cost are required.

The present invention has been made in view of the above circumstances, and in the case where a high step is formed on the side of a passage such as an approach or the like, the winding generated at the step or the upper surface of the step. It is an object of the present invention to reliably prevent a large amount of snowfall by a floor-side configuration, thereby improving safety during traffic.

[0005]

A specific means for achieving the above technical object is to provide a step which is higher than the passage at the side of the passage and partially at the side of the passage. Snow stopper
So that the side edges of the steps are prevented
In the configuration in which the stop shelves are provided, the prevention shelves are provided between the upright supports.
Even if the net is stretched over the entire surface without any gaps
Or a plurality of pieces provided with means for giving vibration or heating
The side of a passage characterized by having a stretched strip body
One side with snow closure and anti-rolling structure.

[0006]

According to the above-mentioned means, when a snow layer is formed on the upper surface of a high step portion present on the side of the passage, even if the snow layer has an extremely high raised body, the side edge of the step portion can be formed. The snow layer is closed and blocked by the action of the preventive shelves attached to the vehicle, so that a large amount of snow does not occur at once even under the influence of wind or the like. Also, even if the snow layer formed on the upper surface of the step portion grows in the horizontal direction and protrudes from the side edge portion of the stub, the protruding portion is cut by the prevention shelf and falls early. . And the prevention shelf is
A plurality of tensioned strips provided with means for
If they have, these tensioning strips vibrate or
Therefore, the cutting of the contact area with the snow layer is further promoted.
Act like

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a snow stopper and anti-roll-over structure according to the present invention. FIG. 1 shows a first embodiment of the present invention, in which a step 2 having a height higher than the passage 1 is formed on a side of a passage 1 having an outer step 1a. A protection shelf 3 is attached along the edge 2a. The prevention shelf 3 is provided at the side edge 2 of the step portion 2.
a standing pillars 4... 4 fixed to a.
… 4, and a plurality of wires (stretched strips) 5… 5, which are arranged at a predetermined pitch in the vertical direction. And stretched so as to extend in the lateral direction.

According to the above-described structure, when a snow layer is formed on the upper surface of the stepped portion 2, even if the snow layer is raised to a high level, it is blocked by the prevention shelf 3, and Even if this snow layer is affected by wind, etc., the shelves 3
Prevents a large amount of snow from falling. FIG.
As shown in the figure, the snow layer X formed on the upper surface of the step portion 2 is
It grows in the horizontal direction under the influence of its own weight and the influence of the wind, and protrudes slightly outward from the wires 5... 5 of the prevention shelf 3. In this case, the position of the wires 5. The portion indicated by the imaginary line Z generates a shearing force due to the weight of the protruding portion X1 of the snow layer X, and as a result, the protruding portion X1 falls downward as shown in FIG. This is because the properties of the snow layer X do not have sufficient strength against shearing force.

[0009] The wires 5 ... 5 are affected by solar radiation and temperature.
Mere or metal wire warmed receiving is not limited to a resin wire or a glass fiber line or the like, heat cut snow layer X by using the heating wire or the like, may be snow melting, or,
A means for applying vibration to the wire 5 may be added so that the protruding portion X1 of the snow layer X is cut and dropped earlier. If wires 5 ... 5 consist of heating wires,
Snow melting occurs at the contact area with the snow layer X, which protrudes.
The early cutting of the portion X1 is promoted. Therefore, snow layer X
Is trying to grow outward from wire 5 ... 5
However, there is a limit to this growth, and a slight overhang X1
Is generated, by the cutting action of the wires 5 ... 5
The protruding portion X1 falls, and the winding as shown in FIG.
It does not grow until the sagging occurs.

[0010] Means for giving vibration to wires 5 ... 5 are added.
In this case, the area around the snow layer
Movement, and the early cutting of the protruding portion X1 is performed as described above.
Disruption is encouraged.

FIG . 4 shows a second embodiment of the present invention.
In the same manner as above, there is a high step portion 2 on the side of the passage 1.
In this configuration, the stepped portion 2 is disposed along the side edge 2a.

The growth of the portion X1 can be eliminated earlier. Obedience
Therefore, also in the case of the second embodiment,
No more large amounts of snow fall and rolling
Can also be reliably prevented.

FIG . 5 shows a third embodiment of the present invention.
In this case as well, in the same manner as the above two examples,
In the configuration having the high step portion 2, the side edge portion 2 of the step portion 2 is provided.

In the above embodiment, each house comes out of a residential area.
Apply the present invention to the approach that is a mounting passage to the entrance
However, even if it is another passage,
In places where high steps are formed
It goes without saying that the present invention can be applied.

[0014]

[Effect of the Invention] As described above, according to the present invention, the side of the passage is provided.
The front shelves were installed on the side edges of the high steps in
The snow layer formed on the upper surface of the stepped section is
It is blocked and a large amount of snow falls at once
And the snow layer is outside the shelves
