Description

[Detailed description of the invention] The present invention relates to a roof snow melting device.

Conventionally, this type of roof snow melting equipment has either a hot water sprinkling pipe installed at the top of the roof and hot water sprinkled from the hot water sprinkling pipe to melt roof snow, or a hot water pipe installed in the attic. In addition, electric surface heating elements were installed in the attic, and
By installing hot air pipes as in Publication No. 31216,
Examples include those configured to melt roof snow using hot water heat, electric heat, steam heat, etc.

However, these conventional configurations have disadvantages in that they are unsuitable for practical use due to insufficient groundwater, increased electricity consumption, and rising equipment costs due to hot water production boilers, steam boilers, and the like.

The present invention aims to provide a roof snow melting device that can eliminate these inconveniences.

Hereinafter, the gist of the present invention will be explained with reference to the accompanying drawings.

In this device, a roof plate member 2 of a building 1 is formed of a folded metal member having a substantially corrugated cross section, and a warm air chamber 4 is formed between the roof plate member 2 and a ceiling wall member 3 of the building 1. , and a melt water gutter section 5 is arranged inside the outer wall member 6 of the building 1 at the downstream edge of the roof sheet member 2, and a melt water separation plate 7 is provided at the bottom of the valley of the roof sheet member 2. A melt water flow path 8 is formed between the melt water separation plate 7 and the bottom surface of the roof plate member 2, and the melt water gutter portion 5
This roof snow melting device is characterized in that a drain pipe 9 is also arranged hanging down inside the outer wall member 6, and the drain pipe 9 is arranged to communicate with a drain 10 or the like.

Further, this example will be specifically explained.

In this embodiment, a raised ceiling part 11 is formed on one side of the warm air chamber 4, an inlet 12 communicating with the inside of the building 1 is formed, and a suction fan 13 is formed in this inlet 12.
In addition, an exhaust port 1 is installed on the other side of the warm room 4.
4, an exhaust fan 15 is installed in this exhaust port 14, and an air vent 17 is formed in the upper wall member 16 of each floor to forcibly introduce the warm air inside the building 1 into the warm air room 4. , I'm trying to exhaust it.

Reference numeral 18 is a kotatsu, and 19 is a stove.

Further, the drain pipe 9 of this embodiment has a heat insulating material wrapped around its outer circumferential surface.

Reference numeral 20 is a water reservoir groove.

Furthermore, an asbestos member 21 for removing dew condensation is disposed on the back surface of the roof plate member 2 of this embodiment.

Further, the melt water separation plate 7 of this embodiment is installed along the length direction of the valley bottom of the roof plate member 2, and water passage holes 22 are formed scattered on the plate surface.

As described above, in the present invention, the roof plate member 2 of the building 1 is formed of a folded metal member having a substantially corrugated cross section, and a warm air chamber 4 is formed between the roof plate member 2 and the ceiling wall member 3 of the building 1. A melt water gutter section 5 is arranged inside the outer wall member 6 of the building 1 at the downstream edge of the roof sheet member 2, and a melt water gutter section 5 is provided at the bottom of the valley of the roof sheet member 2. A plate 7 is disposed, a melt water flow passage 8 is formed between the melt water separation plate 7 and the bottom surface of the roof plate member 2, and a drain pipe 9 is connected to the melt water gutter portion 5. Since the drain pipe 9 is arranged to hang down inside the building 1, and the drain pipe 9 is arranged to communicate with the sewer 10, etc., the warm air inside the building 1, for example, the warm air from a kotatsu, a stove, etc., rises by convection and flows into the warm air room. The interior of the warm air chamber 4 becomes warm, and the warm air in the warm air chamber 4 exchanges heat with the snow on the roof plate member 2, thereby melting the snow.

In other words, the residual heat inside the building 1 performs the snow melting action, eliminating the need for any special heat source, thereby improving economic efficiency.

At this time, since the roof plate member 2 has a substantially wave-shaped cross section, the snow melting area is large, and since it is made of metal, the heat exchange effect is good, and the snow melting effect can be increased accordingly.

Then, the melt water flows down the valley bottom surface of the roof plate member 2 due to the roof slope.

At this time, due to the presence of the melt water separation plate 7, the snow cover S and the melt water are separated, and once the melted water is not sucked up into the snow cover again, the snow melting effect can be improved accordingly, and the melt water separation plate Since the melt water flow path 8 is formed by the melt water flow path 8, the melt water quickly flows down without coming into contact with the snow, and can be prevented from freezing again, thereby improving the water melt effect.

Thereafter, the flowing melt water is collected in the melt water gutter section 5, and then falls through the drain pipe 9 and is drained into the sewer ditch 10 or the like.

At this time, the melt water gutter section 5 and the drain pipe 9 are connected to the building 1.
Since the melt water is disposed inside the outer wall member 6, the flowing melt water is rapidly descended and drained without freezing.
Therefore, the snow melt water passes through the melt water flow path 8, the melt water gutter section 5, the drain pipe 9, and is drained to the sewer 10 etc.
In addition, the water can be rapidly drained without freezing at any position, that is, the melted water can be rapidly drained without freezing, thereby significantly improving the snow melting effect.

As described above, the intended purpose can be fully achieved.
