DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow dome, and more particularly to a snow dome suitable for constructing a dome having a membrane roof structure in an area with a large amount of snow.

[0002]

2. Description of the Related Art In various dome-type buildings having a roof with a membrane structure, measures are taken to melt snow by blowing hot air when there is snow. Generally conceivable countermeasures include laying a heating wire or using hot water.

No. 3529 discloses a snow-melting type membrane roof structure using warm air.

In winter areas where snow is heavy, outdoor activities are restricted, so that a monotonous life is forced during the snow season. On the other hand, the necessity of living brightly with snow without harming the snow is proposed by Mr. Kihei Takahashi, for example, in the book "People in the Snowy Country", where the need to remove the snow roof is required. There are no roof structures and stilt-type living quarters for indoor lighting.

[0005] In recent years, various facilities have begun to appear in snow-covered regions in response to such a proposal, but as Takahashi points out, there is a strong tendency to introduce the structure of facilities in non-snow-covered regions directly into snow-covered regions. Therefore, various problems have arisen. For example, considering the introduction of a dome with a membrane roof structure in a snow-covered area, the snowfall in a non-snow-covered area is as high as three times in one winter season, and the snowfall at one time is unlikely to exceed 30 cm. Therefore, relatively light snow cover measures are sufficient, but in heavy snowfall areas, especially in heavy snowfall areas where daily snow cover is not rarely more than 1 m, unless severe snow cover measures are taken, the situation is similar to the deep snow Kannon in Joetsu. This would lead to an accident again. Even if measures are taken against snow cover, strict and reinforced measures against snow cover in non-snowy areas are extremely disadvantageous because only initial costs and running costs increase. It is urgently necessary to economically realize a bright dome, which is strongly demanded in snowy countries, so that Mr. Takahashi mentioned above can enjoy living with snow.

[0006] However, the membrane roof structure of the warm air system or the snow sliding system mentioned above is disadvantageous because of its high initial cost.

As apparent from the above, an object of the present invention is to clarify a snow-compatible dome which can be constructed at low cost in a snow-covered area, that is, a snowy dome coexisting with snow.

[0008]

The snow-supporting dome according to the present invention has a one-sided roof continuously arranged at the bottom of the membrane roof, and the tip of the upwind side of the one-sided roof is lower than the downwind side. It is lowered to near the surface, the side part has a gentle slope compared to the other parts, and the structure is such that the snow is scattered from the roof part due to the constant wind during the snowy season, the membrane roof is circular or elliptical in cross section And a configuration in which the skirt portion on the windward side is set higher in the direction of the constant wind in the snowy season at the construction site.

[0009]

Next, the present invention will be described in more detail with reference to the accompanying drawings.

FIG. 1 is a schematic side view of a snow-compatible dome according to the present invention.
Reference numeral 20 denotes a single-flow roof portion in the periphery, and arrows indicate the constant wind direction in winter. As is clear from this figure, the snow-compatible dome according to the present invention is constructed based on the direction of the constant wind in the snowy season in the area where the dome is constructed, and the snow that falls on the membrane roof using the wind is used. Is to be scattered and removed.

As shown in FIGS. 1 and 2, in this embodiment,
The line of the skirt 11 of the membrane roof 10 is configured so that the windward side is slightly higher and inclined. The one-sided roof 20 arranged in a skirt around the membrane roof 10 has a windward side 21 with a leeward side 22. , And the tip of the hem thereof is lower on the windward side 21 near the ground surface. Further, the side portion 23 is configured to have a small width and a small inclination angle as compared with other portions.

It is to be noted that the line of the skirt 11 of the membrane roof 10 can be configured to be horizontal, or conversely, the windward side can be slightly lowered. In such a case, the windward side 21 of the skirt-shaped single-flow roof portion 20 is also used.
Is configured to be lower than near the ground surface as compared with the leeward side 22. Further, the configuration in which the tip of the windward side 21 of the one-sided roof 20 is lowered can also be realized by embankment on the ground surface.

The direction in which the line of the skirt 11 of the membrane roof 10 is inclined or horizontal is determined by the configuration of an auxiliary facility disposed around the membrane roof 10. Ancillary facilities are located below the one-sided roof 20. At this time, if facilities requiring height are arranged on the windward side, the line of the skirt 11 of the membrane roof 10 goes upwind, and In this case, the structure is lowered. In addition, the facilities having the same height are used for
, The line of the skirt 11 of the membrane roof 10 becomes horizontal.

The entrance of the dome is preferably provided below the side portion 23 in order to prevent wind from blowing. The reason why the slope of the one-sided roof 20 is made gentle at the side portion 23 is not only that the wind speed is increased by the configuration of this portion, but also that the speed of falling snow from the roof is made slow. Furthermore, it is also possible to provide a flat roof at the doorway to receive and deposit snow.

Since the snow-supporting dome according to the present invention is constructed as described above, when there is a wind from the direction shown by the arrow, the wind blowing to lick near the ground surface has a single-flow roof 2.
As a result, the snow is blown up along the slope of the roof from the windward side 21 of the zero to the side portion 23, and the snow accumulated on the upper surface of the membrane roof 10 is blown off. In the embodiment described above, the membrane roof 10 is configured to have a hemispherical cross section and the skirt-shaped single-flow roof 20 has an elliptical cross section. However, the membrane roof 10 itself can also have an elliptical cross section.

The snow-compatible dome according to the present invention is adapted to the direction of the constant wind in the summer season as a result of being adapted to the direction of the constant wind in the snowy season at the dome construction site.

It should be noted that the snow-compatible dome according to the present invention does not refuse a configuration in which snow melting means such as warm air or a heating wire is also arranged. These configurations are particularly effective during heavy snowfall, and only a measure against snow of the present invention is sufficient for ordinary snowfall.

Further, a portion requiring a sufficient height as a facility may be constituted by the membrane roof 10, and other attached facilities do not require a large height, so that they can be arranged below the single-flow roof 20. . This is effective for minimizing the size of the membrane roof 10 as much as possible.
It has the advantage of not affecting the design.

[0019]

According to the present invention, the snow cover can be prevented without using any special equipment only by considering the shape and orientation, so that both the initial cost and the running cost can be reduced. In addition, the main body of the dome may have the same shape as the conventional one, and the single-sided roof part can be configured using the roof (low-rise part) of the surrounding accessory facilities, and the wind of each dome can be changed without major design changes. There is an advantage that a shape suitable for the environment can be easily realized. Furthermore, since the shape is such that it does not hinder the wind but flows away, the influence on the surrounding wind environment is small.
