[0012] The snow that slides on the roof top surface 1 is heated and heated by the warm water or well water that is stored in the water tank portion 3 as a dam and is heat-exchanged by the heating pipe 4 or flows into the water tank portion 3 from the heating inflow pipe. Water storage promotes snow melting.

Excess snowmelt water is discharged from the discharge hole 5 without overflowing from the water tank 3.

Further, since the dam wall 2 does not have to be erected at the tip of the eaves, it is erected slightly on the ridge side to form the water tank part 3, and the water tank part 3 (the dam wall 2) is closer to the eaves side. In the above, since the inclined surface 6 is formed between the upper part of the dam wall portion 2 and the tip of the eaves, snow is not accumulated between them and snow canopies are formed, and the snow falling on the inclined surface 6 glides down to the eaves. To do.

[0015]

Embodiments of the present invention will be described with reference to the drawings.

At the eaves and side edges of the roof, a dam wall 2 for standing up rainwater and snow melting water flowing down the roof top surface 1 toward the eaves side is erected, and the dam wall 2 and the roof top surface 1 form rainwater. A water tank portion 3 for storing snowmelt water is formed.

A heating pipe 4 for heating or heating the dammed snow or snow-melting water is arranged in the water tank 3.

The heating pipe 4 is constructed so that hot water heated by the boiler 9 or ground water warmer than the outside air temperature is pumped to heat it by heat exchange.

Even if the heating pipe 4 is not provided in the water tank portion 3 as described above, a heating inflow pipe is provided so that well water, ground water or the like which is warmer than the heating water or the snow melting water can be directly introduced. The stored water may be heated to warm the stored water.

Further, a drain hole 5 for preventing overflow is provided at a predetermined height of the dam wall portion 2 on the side of the water tank portion 3 so as to prevent water from being stored above this height.

Further, an inclined surface 6 is provided between the upper portion of the dam wall portion 2 of the water tank portion 3 and the eave tip end portion of the roof and the side edge of the roof.
And the inclined surface 6 is formed continuously in the peripheral portion of the roof. Therefore, rainwater and snowmelt water flow on the roof top surface 1 toward the eaves side and are dammed up by the damming wall 2 and the water tank 3
And is heated or heated by the heating tube 4. The snow that slides on the roof top surface 1 is stored in the water tank portion 3 as a dam and is heated or heated by the heating pipe 4 to promote snow melting.

Excess snow melting water is discharged from the discharge hole 5 without overflowing from the water tank 3.

Since the dam wall portion 2 does not have to be erected at the tip of the eaves, it is erected slightly on the ridge side to form the water tank portion 3 and the water tank portion 3 (the dam wall portion 2) is closer to the eaves side. In the above, since the inclined surface 6 is formed between the upper part of the dam wall portion 2 and the tip of the eaves, snow is not accumulated between them and snow canopies are formed, and the snow falling on the inclined surface 6 glides down to the eaves. To do.

As described above, unlike the conventional example, this embodiment forms the water tank portion 3 by standing the dam wall portion 2 on the existing roof material, so that the construction is easy and the existing roof is also easy. Moreover, since the water tank portion 3 is provided on the ridge side rather than at the edge of the eaves, it is easy to implement in this sense and is excellent in safety. Further, since the sloped surface 6 is provided at the eaves portion because it is provided on the slightly peak side, no eaves or the like is formed around the roof as described above.

Further, a water bearing support 7 having water through holes such as a punching metal or a perforated plate that does not allow snow to come into contact with the bottom of the water tank 3 is installed at a position above the bottom.

Therefore, since the snow slid and stored in the water tank portion 3 is immersed in the water while being supported by the water-passing support 7, the snow-melting effect of the snow is further improved.

Further, a heating pipe 8 for heating or heating the roof top surface 1 to promote melting of snow or sliding to the eaves side is also provided inside the roof slope and the slope 6. .

Therefore, the snow falling on the roof slope and the slope 6 is less likely to accumulate, the snow falling on the roof slope easily slides to the water tank 3, and the snow falling on the slope 6 slides down the eaves. It will be easier.

Since the present invention is constructed as described above, the water tank portion can be formed by simply erecting the damming wall portion on the eaves of the roof, so that the water tank portion can be manufactured very easily.
It is a snow melting device for roofs with excellent practicality that can be easily applied to existing roofs.

Moreover, since this water tank does not have to be erected at the tip of the eaves and is not formed at the tip of the eaves, the manufacturing is simple and excellent in this respect as well, and a dam wall is provided at the tip of the eaves. Since an inclined surface formed between the upper parts is provided,
A snow melting device for roofs with extremely excellent practicality is achieved without the formation of eaves or the like at the eaves.

Further, since the heating pipe or the heating inflow pipe is provided in the water tank portion, the snow melting effect is improved, and since there is no overflow due to the discharge hole, the snow melting device for the roof is more practical.

According to the second aspect of the present invention, the snow stored by sliding in the water tank portion is immersed in the state of being supported by the water-passing support, so that the snow melting effect is further improved.

According to the third aspect of the invention, the snow falling on the roof slope becomes less likely to be covered with snow, and the snow falling on the roof slope easily slides into the water tank.

Further, according to the invention as defined in claim 4, there is provided an excellent snow melting device for a roof, in which a snow visor is hardly formed around the roof.
