必要がある。``Conventional technology'' Roofs with arched membrane structures do not have support in the center, so when snow accumulates, it is necessary to slide off the snow before the amount of snow accumulates too much, or the roof is exposed to light. In order to take advantage of the membrane structure's ability to transmit light, it is necessary to slide the snow off.

より滑り落すようにしている。Therefore, as shown in Figure 4, an infrared irradiation device B is placed below the arched single roof A, and when snow accumulates on the membrane roof, the infrared irradiation device irradiates the membrane roof with infrared rays. The surface temperature of the membrane surface is raised to 1, melting the snow in the area in contact with the membrane surface and causing the snow on the membrane roof 1- to slide off.

が多くなって不経１斉であった。(Problem to be solved by the invention) Conventionally, in order to remove snow from arch-shaped membrane roofs, the membrane roof surface is illuminated with infrared rays! The snow on both sides of the top is connected 1. In some cases, the snow is stuck to the top of the membrane roof and cannot be removed. In such cases, it is necessary to continue irradiating infrared rays more than necessary, resulting in increased energy consumption and a waste of time.

膜屋根に接する積雪面を融雪装置により加熱して融かし
、積雪を膜屋根の傾斜面にＫ）って自重で滑り落とす。The snow sliding method for a dome-shaped membrane roof according to the present invention involves attaching heating elements along lines extending radially from the top of the membrane roof, and dividing the snow on the membrane roof into the radial lines. The snow-covered surface in contact with the roof is heated and melted by a snow-melting device, and the snow falls onto the slope of the membrane roof and slides off under its own weight.

滑べり落ちる。"Operation" According to the 12th stage, the snow on the membrane roof can be melted by the heating elements arranged on one or more lines, and the snow on the +1 roof -L can be divided. Therefore, if the snow layer on the roof side is melted, the divided snow layer will not be stopped anywhere and will slide down due to its own weight along the slope of the +1!2 roof.
なお膜屋根は熱の伝達が速いので、融雪装置で加熱され
た場合、容易に膜屋根に接した部分の雪を融かすことが
