Description

  TECHNICAL FIELD The present invention relates to a snow ridge occurrence prevention device installed on a roof of a snow-free construction.

  In the heavy snow region, there are many houses that use snow-free construction. The snow-free construction is to process the snow on the roof naturally without removing it (snow removal). There is an advantage that it is difficult to form an icicle like a triangular roof, but there is a case where a snow ridge is generated. A snow leopard is a lump of snow that is blown in one direction on the roof of snow-free snow. 2. Description of the Related Art Conventionally, as a countermeasure against a snowfall, a snowfall prevention device that does not generate a snowfall is provided (for example, Patent Document 1).

Utility Model Registration No. 3094983

  The snowfall prevention device of Patent Document 1 is a snowfall generation prevention device installed with the inclined surface facing the windward side, and the inclined surface rises about 45 ° to 60 ° from the horizontal plane, It is a curved surface composed of an upper inclined plate that stands up from about 75 ° to 80 ° from a horizontal plane that continues above the lower inclined plate. Since the inclined surface is a bent surface, the lower inclined plate guides the wind to the upper inclined plate, and the upper inclined plate smoothly directs the wind guided from the lower inclined plate to increase the wind speed. The position of the vortex generated in the leeward can be separated from the wall surface to prevent the occurrence of snowfall.

The device for preventing snowfall of Patent Literature 1 uses an inclined surface to separate the position of a vortex generated in the lee of a building from the wall surface to prevent the occurrence of snowfall. Moreover, it becomes difficult to accumulate snow on an inclined surface by making an inclined surface into a bending surface.
However, when there is snow on the inclined surface, there was a case where a snowfall occurred beyond the upper inclined plate.

  The present invention solves the above-described problems, and an object of the present invention is to provide an apparatus for preventing the formation of snow scum that prevents snow scum from being generated by melting snow accumulated on the apparatus.

The apparatus for preventing occurrence of snowfall of the present invention is provided with a plate-shaped snowfall prevention plate provided with a large number of holes provided vertically on the wall surface of the caps of a snow-free roof, and a number of holes for receiving snow accumulated on the upper surface of the caps. And a snow receiving plate pedestal extending from the snow icing preventing plate to the top of the headboard, and fixed to the snow receiving plate pedestal. A space is placed between the snow receiving plate and the headboard so that no snow accumulates by placing the plate and the snow receiving plate above the headboard, and the snow that accumulates on the snow receiving plate due to a rise in the temperature of the space due to a rise in the outside air temperature. It is made to melt .
Further, the snow receiving plate rest is provided with a lifting member for supporting the snow receiving plate at a predetermined height and adjusting the height .

  The apparatus for preventing the occurrence of snowfall according to the present invention is provided with a snow receiving plate for receiving snow accumulated on the upper surface of the headboard. Due to the space formed below the snow receiving plate by the snow receiving plate, the snow that accumulates on the snow receiving plate is melted on a fine day, so that it is possible to prevent the generation of snow traps beyond the snow bag generating prevention device.

It is a front view of the snow jar occurrence prevention device of the present invention. It is AA sectional drawing of FIG. It is a BB end view of Drawing 1, and is a figure showing the condition of use of the snowfall prevention device of Drawing 1.

  The present invention realizes that the snowfall of the snowfall prevention device is melted to prevent the occurrence of snowfall.

The apparatus for preventing snow scum occurrence of the present invention is described. FIG. 1 is a front view of an apparatus for preventing the occurrence of snow plow according to the present invention. FIG. 2 is a cross-sectional view taken along the line AA of FIG. 3 is a cross-sectional view taken along the line BB in FIG. 1 and shows a usage state of the snow scum occurrence prevention device in FIG.
The apparatus 10 for preventing occurrence of snowfall of the present invention includes a snowfall prevention plate 14 provided perpendicularly to the upper surface of a cap 12a (parapet) of the snow-free roof 12, and a snow receiving plate 16 provided above the cap 12a. Moreover, the space 18 is formed between the snow receiving plate 16 and the headboard 12a by providing the snow receiving plate 16 above the headboard 12a.

The snowfall prevention plate 14 is a plate having a predetermined height and width provided perpendicular to the headboard 12a of the snowless roof 12. In the snow-free roof 12, when the snow 20 is piled up on the top surface of the headboard 12a and the roof body 12b, and the wind blows from the roof body 12b toward the headboard 12a, a snow ridge (snow lump) extending from the headboard 12a toward the wall surface. appear. By providing the snow scum generation prevention plate 14 at a predetermined height on the top surface of the scab 12a, it is possible to prevent the generation of a sag that occurs on the sag 12a.
1 is provided with a large number of holes 14a (FIG. 3).
The snowfall prevention plate 14 is fixed vertically to the first base 22 attached to the outer edge of the headboard 12a. The first base 22 is a metal plate formed in a U shape, and is attached so as to cover the edge portion of the headboard 12a.

A snow receiving plate stand 24 extending from the prevention plate 14 to the top of the headboard 12a is fixed to the snow pail generation prevention plate 14. The snow receiving plate rest 24 is in the shape of a square member, and a plurality of the snow receiving plate rests 24 are fixed to the snow pail generation preventing plate 14 at a predetermined interval. The snow receiving plate rest 24 is provided longer than the width of the headboard 12a.
The snow receiving plate rest 24 is provided with an elevating member 26 for adjusting the height thereof. The elevating member 26 is fixed to a second base 28 attached to the inner edge of the headboard 12a. The second base 28 is the same member as the first base 22.

1 to 3, a plate-like snow receiving plate 16 is placed on a snow receiving plate placing table 24. At this time, since the snow receiving plate 16 is disposed above the headboard 12a, a space 18 is formed between the snow receiving plate 16 and the headboard 12a. It is assumed that the snow receiving plate 16 is provided with a large number of holes 16a (FIG. 3).
In the snowfall prevention device 10, the snow receiving plate 16 is provided above the headboard 12a, so that the snow 20 does not accumulate on the headboard 12a during snowfall. That is, a space 18 in which the snow 20 does not accumulate is formed below the snow receiving plate 16.
During the snowfall, snow 20 is piled up on the snow candy occurrence prevention plate 14 and the snow receiving plate 16 (FIG. 3). When the snow stops and the weather becomes clear, the temperature of the outside air 30 rises. At this time, the temperature of the space 18 also rises. When the temperature of the space 18 rises, the snow 20 (snow 20a close to the space 18) that accumulates on the snow receiving plate 16 starts to melt. When the snow 20a close to the space 18 starts to melt, the snow 20b approaches the space 18 and melts due to the weight of the snow (20b) above the snow 20. As described above, according to the snow ridge generation preventing apparatus 10 of the present invention, the snow cover 20 around the space 18 is melted in fine weather. The water 32 generated by the melting of the snow flows from the hole 16a of the snow receiving plate 16 through the upper surface of the headboard 12a, flows into the snow-free snow roof main body 12b, and is discharged to the cage (not shown) of the snow-free snow roof 12. Further, the snow accumulation 20 of the snow-free roof main body 12b is also melted by the temperature rise of the outside air 30 and the flow of water 32.
In the first snowfall, when the wind blows toward the leeward (Kasagi 12a), the snow 20 blows into the space 18, but the snow 20 blown into the space 18 melts in fine weather. In addition, since there is snow 20 on the snow receiving plate 16, the snow 20 does not accumulate in the space 18 during subsequent snowfall.

As described above, the snow scum occurrence prevention device of the present invention has a snow melting function. According to the present invention, the snow that has accumulated on the snow receiving plate or the snow-falling roof body during snowfall is gradually melted as it is in clear weather (that is, without snow removal) (FIG. 3). Snow can be reduced by the time of snowfall. As a result, it is possible to prevent a snowfall from occurring beyond the snowfall prevention plate. The apparatus for preventing occurrence of snowfall of the present invention prevents the occurrence of snowfall by melting snow on a snow-free roof.
On the other hand, the conventional snowfall prevention device (Patent Document 1) prevents the accumulation of snowfall by preventing snow accumulation. However, since there is no component that melts snow, snowfall continues in the snowfall prevention device, and snowfall may occur beyond the upper inclined plate.
In addition, as shown in FIG.1 and FIG.2, you may provide the reinforcing material 34 which fixes the snow candy generation | occurrence | production prevention board 14 and the snow receiving board stand 24. As shown in FIG.
