。[Problems to be Solved by the Invention] The prior art described above has the following problems. In other words, snow eaves suppression devices such as retaining walls and chain-link fences are installed vertically, which creates turbulence in wind flow and accumulates snow, which can have the opposite effect. Chain-link fences do not separate the snow on top of the structures, and they also reduce wind speed, which actually encourages snow eaves. The present application has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to provide a device that can do the following. That is, the present invention aims to smooth the flow of wind, allow snow to fall naturally while still being lightweight, and prevent snow from forming on top of construction structures, thereby helping to reduce the number of maintenance personnel.

When the surface plate is shaped like an arc, the center angle of the arc is preferably around 60°.
If the center angle is 90°, the top will be a horizontal surface, which will cause a snow cap. In addition, since the surface plate can be painted, it can be colored to match the color of the structure or the environment.Painting improves snow sliding properties and suppresses snow accumulation and snow accumulation. Furthermore, by using solar cells and electricity for the surface plate material,
A heating element can be attached to the top plate, or the top plate itself can be made to generate heat. In addition, if the surface of the top plate is covered with snow due to local conditions, it is also possible to move a linear object parallel to the top plate to separate the top plate from the snow and allow it to fall. The lower member 4A3 has a hole 4A31 for an anchor bolt 9 to be installed on the frame, and below the vertical member 4A2 is an extension leg 7 for coping with cases where the frame is sloped, uneven, etc. Bolt holes 4A32 are drilled for bolts B to connect the vertical members 4A2, and when the snow eave prevention plates are installed in parallel, they can be connected to the adjacent ones and can be used alone. To prevent falling, a bolt hole 4A33 for a bolt B that locks the back surface connecting member 8 is provided. The wind direction converter 6 is formed by forming a connecting piece 6B bent upward on one edge of a plate 6A having a predetermined width.
is attached to a predetermined location on the vertical member 4A2 of the frame 4 in an inclined state when viewed from the front. 4A34 is a bolt hole for attaching this wind direction converter 6. In this case, the support angle of the wind direction converter 6 will be determined according to the condition of the installation location of the snow eaves prevention device.

As described above, it is installed and fixed to the upper part 2 of a structure such as a tunnel, an overpass, a retaining wall, or a shelter entrance using anchor bolts 9 or the like. In this case, it goes without saying that it can be removed by loosening the anchor bolts 9 and the like, or that it can be replaced with another snow eaves prevention plate. When the snow eave prevention plates 3 are installed in parallel in this way, the adjacent snow eave prevention plates 3 can be placed in close contact with each other, or they can be provided with a certain distance D by using the back connecting material 8. By spacing them apart, even if snow falls on the eaves prevention board, it prevents the snow from snowing next to it and allows the snow to fall while it is lightweight. The height of the snow eave prevention board can be approximately 70% of the maximum snow depth in each region, and it does not create a feeling of pressure when installed on a structure, and it is an economical board that corresponds to the local conditions. be.

る。[Effects of the Invention] Since the present invention is constructed as described above, it produces the following effects. Each snow eave prevention plate has a slope on the front to smooth the flow of wind and allow snow to fall off naturally.It is also easy to install on-site as it is made into a single product and can be attached to the frame with anchor bolts. Since they are installed in parallel on the top of a construction structure, a series of snow eaves prevention effects can be obtained. When the snow eave prevention boards configured as described above are installed in parallel, they are spaced apart to a certain extent so that even if snow accumulates on the snow eave prevention boards, the snow will not be piled up and the snow will slide off. be. Since the snow eave prevention board has an inner cavity, the wind from the back passes through the inner space of the snow eave prevention board that is lined up in parallel, becomes hollow and increases the wind speed, and snow does not accumulate in the inner space of the snow eave prevention board. It's also effective. Therefore, since snow does not accumulate within the snow eave prevention plate, it is effective in preventing the formation of icicles and the like even when snow freezes and thaws. In areas with heavy snowfall, by installing a wind direction converter on the back, it is possible to utilize wind from the sides, suppress snow accumulation on the back, reduce snow accumulation, and reduce the height of the snow eaves prevention board. Additionally, the shape can be changed depending on the local conditions and wind direction at each site, and it can also be replaced.
