る。The fence 4 is provided with a wind oscillating member 21 for preventing snow accumulation as a snow accumulation prevention structure. As shown in FIGS. Then, the upper part of the wind oscillating member 21 is connected to the fence 4
And the lower part is fixed to the road-side end face 3T of the roof 3. The wind oscillating member 21 can be made of a flexible sheet such as a cloth sheet, a resin sheet, a rubber sheet, or rather, a blind or a net. What moves, that is, swings and vibrates is used. In addition, the wind oscillating member 21
The side surface of the road is preferably made to have a low friction surface by Teflon processing or the like, and preferably has waterproofness by waterproof processing or the like. As shown in the perspective view of FIG.
An iron plate, a wooden plate, a resin plate, or a rod made of such a material is used as the mounting member 22. The mounting member 22 is provided over substantially the entire length of the wind oscillating member 21 in this example. The wind oscillating member 21 is wound around the mounting member 22, and is fixed by bonding or welding. The upper one becomes the fence mounting member 22, and the lower one becomes the roof mounting member 22. In the case of a meeting, the end of the wind oscillating member 21 is formed in a bag shape, and the attachment member 22 is attached to the bag-shaped portion.
Should be inserted and fixed. Then, a fixing means 23 such as a bolt and nut is inserted into the upper mounting member 22 and fixed to the upper portion of the support post 7, and the lower mounting member 22 is fixed to the end face of the roof 3 by fixing means 24 such as an anchor. Fix to 3T. By providing the mounting member 22 on the upper part of the wind oscillating member 21, the upper part of the wind oscillating member 21 can be easily mounted between the columns 7, 7,. Thereby, the lower part of the wind oscillating member 21 can be attached to the end face 3T of the roof 3 without any gap.

である。Next, the operation of the above configuration will be described. When the snow falls in winter, since the road side surface of the fence 4 is shielded by the wind oscillating member 21, it is possible to prevent snow on the fence 4, Since the wind oscillating member 21 is provided obliquely, the snow falling on the oscillating member 21 falls downward along the inclination. Further, even if snow adheres to the wind oscillating member 21, the wind oscillating member 21 oscillates when receiving wind, so that the snow is shaken off, and a snow mass is formed on the wind oscillating member 21. There is no. If the oscillating member 21 is sheet-shaped, it is easy to oscillate in response to wind. On the other hand, if the oscillating member 21 has air permeability such as a blind or a net, the oscillating member 21 is suitable for a strong wind. It can be selected according to.

The wind oscillating member 21 is inclined between the upper part of the fence 4 and the end face 3T of the roof 3, and the fence 4 is provided with a wind oscillating member 21 for preventing snow accumulation. From
The snow that has fallen on the wind swinging member 21 covering the fence 4 falls before the swinging member 21 rocks because the swinging member 21 swings by the wind,
Snowing on the fence 4 can be prevented, and falling of snow or ice blocks from the roof 3 of the protective structure can be prevented. Further, the swinging member
The snow that has fallen due to the swing of the swing member 21 falls down from the end face side of the roof 3 to below the roof 3 due to the oblique arrangement of the swing member 21, so that it is difficult for the snow to fall on the swing member 21 even in the absence of wind. It can be dropped before it clumps.
