Description

  The present invention relates to a snowfall prevention member that is installed on the outer edge of a building and prevents the formation of snowfall, and more specifically, the main body portion of the snowfall prevention member having a main body portion formed in a substantially right-angled triangle shape is configured. It is related with the panel member to do.

  Conventionally, in cold regions, snowfall prevention members have been installed at the upper edge of the building, and snow that has fallen on the top of the building is blown away by the wind passing through the top of the building. Winding wind that engulfes the wind and passes through the upper part of the outer edge of the building, and the wind wind that rotates along the outer wall of the building creates snow traps that grow when the snow in the wind adheres to the upper part of the outer edge of the building and grows Is prevented by this snow candy preventing member (see, for example, Patent Document 1).

  However, depending on the wind power of the wind that blows, the snow that flies with the wind can not get over the inclined panel surface of the main body part formed in a substantially right triangle shape in the cross section of the snow leopard prevention member without sticking to the inclined panel surface, In addition, there is a risk of strongly colliding with the inclined panel surface and adhering to the inclined panel surface.

  Therefore, as described above, when snow adheres to the inclined panel surface of the main body, new snow adheres to the first adhering snow, and the snow eventually accumulates higher than the upper end of the sag prevention member. There has been a risk of causing snowfall on the upper end of the snowfall prevention member.

Japanese Patent Laid-Open No. 7-166661 (pages 1 to 5, FIGS. 1 to 3)

  According to the present invention, it is possible to provide a snow leopard prevention member capable of reducing the rate at which snow adheres to the inclined panel surface in the main body without being affected by the wind of the wind passing through the upper part of the building.

In order to solve the above-described problem, a snowfall prevention member according to the present invention is a snowfall prevention member having a substantially right-angled triangular cross section that is installed on the outer edge of a building to prevent the formation of a snowfall. Each of the vertical panel located on the outer edge side and the inclined panel inclined downward from the upper end of the vertical panel toward the inside of the building is constituted by a panel member having air permeability.
Further, the upper end portion of the inclined panel is vertically raised along the vertical panel.

  Further, the fore edge panel to be mounted in the left and right fore edge opening portion of the snow scum prevention member is composed of a panel member having air permeability.

  Further, the vertical panel, the inclined panel, and the fore edge panel are made of a punching metal material in which a large number of through holes penetrating both the front and back surfaces of the panel are provided.

  According to the snowfall prevention member of the present invention, at least the vertical panel and the inclined panel in the main body portion of the snowfall prevention member are made of a punching metal material in which a large number of through holes are arranged. A part of the wind passing through the upper part can pass through the punching metal material through-holes of the vertical panel and the inclined panel and pass through the inside of the main body part of the snow candy preventing member.

  Therefore, part of the wind that passes through the top of the building that hits the vertical panel can pass through the body part of the snow skein prevention member, so that it fell on the snow and on the top of the building. Even when snow is caught, a part of the wind hitting the vertical panel passes through the punched metal material of the vertical panel and the tilted panel together with the snow caught in the wind, and enters the body part of the snow haze prevention member. You can go through.

  As a result, the snow that could not be passed over the inclined panel surface of the main body by wind or the snow that could strongly collide with the inclined panel surface and adhere to the inclined panel surface was And the through hole of the punching metal material that constitutes the slant panel) and can pass through the inside of the main body portion of the snowfall prevention member, so that it is difficult for the snow to adhere to the slant panel surface in the main body portion.

  And, by configuring the body part of the snowfall prevention member with a punching metal material in which a large number of through-holes are arranged, when the weather is sunny when the sun shines, the sunlight falls into this body part. Since it enters from the through hole, the snow remaining without being able to pass through the main body with the wind can also be melted by the sunlight.

  Further, since at least the vertical panel and the inclined panel in the main body portion of the snow scum prevention member are made of a punching metal material having a large number of through holes, the snow sack prevention member can be reduced in weight, and the snow sack prevention member The weight burden on the building where it is installed can be reduced.

  Furthermore, since the snowfall prevention member can be reduced in weight, even when the snowfall prevention member is transported by a vehicle, more snowfall prevention members can be transported, and transportation efficiency can be improved.

  And since the part where the snowfall prevention member is installed is the upper part of the outer edge of the building, there is a risk of falling if you step on the foot. Adjustment can be facilitated, and safety in the arrangement adjustment work can be improved.

DETAILED DESCRIPTION OF THE INVENTION Hereinafter, a snowfall prevention member of the present invention will be described with reference to the accompanying drawings.
In the snowfall prevention member 1, the vertical panel 2 and the inclined panel 4 of the main body are made of a punching metal material in which a large number of through holes 3 and 5 are arranged.

  Moreover, the snowfall prevention member 1 shown in FIG. 5 mounts the fore edge panel 9 which arrange | positions many through-holes 10 in the forehead opening part of the snowfall prevention member 1 shown in FIG.

  Further, as shown in FIG. 2, a space 8 is formed in the main body portion composed of the vertical panel 2 and the inclined panel 4.

  When the wind 12 entraining the snow 11 blows on the surface of the inclined panel 4 in the main body of the snow leopard prevention member 1, it functions as shown in FIGS. 3 and 4.

  FIG. 3 shows the flow of the wind 12 in the snow leopard prevention member 1 when the wind force of the wind 12 is weak. In this case, since the cushion of air generated on the surface of the inclined panel 4 by the blowing of the wind 12 is small, the inclined panel Almost all of the wind 12 involving the snow 11 hitting the four surfaces passes through the through holes 5 of the inclined panel 4 in the main body portion of the snowfall prevention member 1 together with the snow 11 to pass through the space 8 in the main body portion and the through holes 3 of the vertical panel 2. Pass through and pass out of the building.

  Therefore, even when the wind 12 is weak and the snow 11 cannot ride over the inclined panel 4 on the wind 12, the ratio of the snow 11 to the inclined panel 4 surface is small.

  FIG. 4 shows the flow of the wind 12 in the snow leopard prevention member 1 when the wind 12 is strong. In this case, the cushion of air generated on the inclined panel 4 surface by the blowing of the wind 12 becomes large. Contrary to the case where the wind force 12 of the wind 12 is weak, most of the wind 12 involving the snow 11 hitting the surface of the inclined panel 4 along with the snow 11 along the inclined panel 4 surface in the main body portion of the snowfall prevention member 1 is provided. It flows upward on four sides and blows out from the upper end of the inclined panel 4 to the outside of the building.

  Further, the snow 11 and the wind 12 that pass through the through-hole 5 of the inclined panel 4 against the air cushion generated on the surface of the inclined panel 4 pass through the space 8 in the main body part and the through-hole 3 of the vertical panel 2, Pass through the building as it is.

  The ratio of the through holes 3 and 5 in the vertical panel 2 and the inclined panel 4 is preferably about 30 to 55% for the vertical panel and about 25 to 50% for the inclined panel. If the opening ratio is less than 1, the air permeability of the member according to the present invention is not sufficiently secured, and if the opening ratio exceeds the upper limit, the rigidity of the entire member may be reduced.

  In addition, although the small edge panel 9 is less likely to be directly blown by the wind, the ratio of the through holes 10 in the small edge panel 9 is preferably about 10 to 35%, and the reason for setting the range of the opening ratio is also the vertical panel described above. This is the same as the reason for setting the aperture ratio range in the inclined panel.

  The shape of the opening of the through hole is circular in the drawings shown in the embodiments, but may be another opening shape such as an oval or an ellipse.

  Further, the surface of the vertical panel 2, the inclined panel 4, and the fore edge panel 9 may be subjected to fluorine processing or the like having a large water repellency.

  Reference numeral 6 in the drawings of the embodiment is a bottom formed by bending the vertical panel 2, and reference numeral 7 is a screw that fixes the inclined panel 4 and the fore edge panel 9.
