  The above-described problem is solved by a roof snow melting structure characterized in that a carbon sheet is provided on the back surface of a metal roof board so as to span a snowy part and a snowless part that receives solar radiation. (First invention).

  The carbon sheet is a sheet material also referred to as a graphite sheet or the like, which is obtained by heating expanded graphite into a sheet shape at a high temperature, and has a layered crystal structure and a large thermal conductivity in the plane direction. The thermal conductivity in the thickness direction has a specific thermal conductivity characteristic that it is relatively smaller than that in the plane direction.

  In the above-mentioned roof snow melting structure, by adopting a carbon sheet whose thermal conductivity in the plane direction is higher than the thermal conductivity in the thickness direction, it was transmitted to the carbon sheet part present in the snow-free part that receives solar radiation. Solar heat is transmitted quickly and widely to the carbon sheet part existing in the snowy part, and the snow in the snowy part is melted by the heat, and the snow on the roof can be melted effectively without electricity. it can.

  Moreover, since the carbon sheet is in the form of a sheet, it is advantageous in terms of space on the back surface of the metal roof plate, and can be easily installed, and since the snow melting effect is exhibited by the carbon sheet alone, The structure is also simple.

  Furthermore, since the carbon sheet is provided on the back surface of the metal roof plate, solar heat is efficiently transmitted to the carbon sheet through the metal roof plate, and is further protected by the metal roof plate.

  Moreover, said subject is solved by the snow melting structure characterized by the carbon sheet being provided so that it may extend over a snow part and a snow-free part which receives solar radiation (2nd invention). That is, the snow melting structure of the present invention is not limited to the roof, and can be used in various places to effectively melt snow without electricity, and it can be realized with a simple structure without being overwhelmed. .

  In the first and second inventions described above, a local snow melting mechanism for forming a snow-free part that receives solar radiation may be provided (third invention). In this case, even if the snowy part and the snowless part are not formed naturally, it can be formed reliably, and the local snow melting mechanism is an electric type. Regardless of whether it is a non-electric type, as long as it can melt snow locally, it does not become a large scale, does not require a large installation space, even when using electricity The amount of power used can be reduced.

  In addition, the above problem is solved by a hut temperature improving structure characterized in that a carbon sheet is provided on the back side and / or shed of the roof material so that a part of the carbon sheet faces the outdoor side. Is done.

  In this hut temperature improvement structure, a carbon sheet having a higher thermal conductivity in the plane direction than the thermal conductivity in the thickness direction is adopted, so that the carbon sheet can be used on the back side of the roof material and / or the shed. The received heat is quickly transmitted over a wide area to the portion of the carbon sheet facing the outdoor side, and the heat is dissipated to the outdoor side, so that the temperature of the back of the cabin can be effectively improved. In particular, when the carbon sheet is provided on the back surface side of the roofing material, the improvement of the hut temperature can be realized with a simple structure without being overwhelmed.

  Since the roof snow melting structure and the snow melting structure of the present invention are as described above, snow can be melted effectively without electricity, and it can be realized with a simple structure without being overwhelmed. it can.
