Description

[Detailed description of the invention] [Industrial application field] This invention prevents snowmelt water melted by artificial energy such as electricity, gas, and oil from freezing again, while allowing it to flow naturally. This invention relates to a snow-melting roof that discharges snow to the ground and protects the roof of a building from damage caused by snow accumulation or freezing.

[Conventional technology] Removing snow from the roofs of buildings in snowy areas is a serious problem in daily life, and research on countermeasures and practical application is being conducted in various fields to overcome this problem, but the results are still not satisfactory. No solution has been found. As a result, destruction of buildings and accidents involving people are occurring every year.

The main measures currently being taken to prevent such disasters are as follows.

(1) Manual snow removal.

(2) A method in which heating waste heat is led into the attic and the stored heat indirectly warms the roof and melts snow.

(3) A method of melting snow by laying electric heating materials on the roof and converting electrical energy into thermal energy.

(4) A method of installing a heat pipe heating section on the roof and melting snow using thermal energy transmitted from other heat sources.

(5) A method in which water pipes are installed on the roof, hot water heated by another heat source is passed through the pipes, and snow is melted by the heat radiated from the pipes.

(6) A method of melting snow by sprinkling underground water on the roof.

(7) A method of mechanically removing snow by spreading tent cloth on the roof and vibrating it.

In this case, if the snow on the roof exceeds a certain value, or if it becomes frozen after being loosened by solar heat or warm air, it will be very difficult to melt the snow.
It is desirable to melt snow before snowfall exceeds a certain value.

[Problems that the invention aims to solve] By the way, when snow is melted using the conventional snow melting method described above, if there is a mistake in the treatment of the melt water, it will freeze immediately when the temperature is below freezing, and the subsequent flow of melt water will be inhibited. As a result, ice blocks develop and increase in size. In particular, if a snow stopper (see number 3 in Figure 1) is installed in the middle of the roof, the snow on the roof will try to melt and flow down to the eaves, but the snow near the stop will freeze. Water from melting snow accumulates in this area, and this water leaks into the attic, causing problems such as so-called gas leaks. Therefore, when trying to melt and melt snow using artificial energy, an important point is how to treat the melt water flowing on the roof. This invention was made against this background and aims to provide a snow-melting roof that can drain snow-melting water without freezing it.

[Means for Solving the Problems] In order to solve the above problems, this invention is based on a snow catcher installed horizontally on the roof, and a roof section and eaves gutter located below the snow catcher from above. It is characterized by comprising a covering part attached to cover the roof, a first heating means for heating the inside of the covering part, and a second heating means for heating the roof.

[Operation] According to the above configuration, the snow accumulated on the roof is
The snow is melted by the heating means, and the melted water is drained through between the cover and the roof. In this case, the interior of the cover is shielded from the outside air and warmed by the first heating means, so the melt water does not freeze.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

In FIGS. 1 to 3, reference numeral 1 indicates a roof made of metal plate tiles and sticks. In the direction of the slope of the roof 1, tile rods 2, 2... are installed side by side at intervals of about 45 cm, and colored iron plates are joined at these parts. In addition, on top of the tile rod 2, perpendicular to this, there is a cross-sectional inverted L
A letter-shaped snow stopper 3 is erected. This snow stopper 3
is a metal member that prevents inconveniences such as snow falling all at once and jumping into neighboring houses, etc.

Roof part 1a and gable part 1 below the snow stopper 3
b is provided with a cover portion 5 that covers these. The cover part 5 consists of a double roof part 5a installed on the tile bar 2 parallel to the roof part 1A, and a double gable part 5b parallel to the gable part 1b.
The upper end of the snow stopper 3 is fixed to the snow stopper 3, and the double gable part 5b is attached to the gable part 1b via a plate member 6 and a fitting 7. Further, an eaves gutter 8 having a U-shaped cross section is provided in the space formed between the gable part 1b and the double gable part 5b, and is adapted to receive drainage from the roof 1. The waste water collected in the eaves gutter 8 is sent to an underground reservoir 11 through a gutter 9 and a downspout 10, and flows into a side gutter 12 due to an overflow phenomenon to be drained.
Here, each of the gutter 9, 10 is made of a heat insulating material,
It is designed to block out the cold air from outside. Also,
Both sides of the roof portion 1a and the cover portion 5 are also shielded from the outside (for convenience of explanation, this shielding member is not shown in FIG. 1).

Next, the heating means of this embodiment will be explained.

First, inside the tile rod 2, there is a heat pipe 21.
(second heating means) is housed therein. That is,
Inside the tile rod 2, there is a U-shaped fishing rod 2 with a width of about 5 cm.
2 are provided at appropriate intervals, and the rising part of the collar iron plate is fixed to the back plate of the roof 1, and a long fishing rod 23 is inserted inside the fishing rod 22. A heat pipe 21 is housed inside. In addition, the upper part of the tile rod 2 is connected to the cap 24.
Closed by.

The lower end 21a of the heat pipe 21 is bent into an L shape and inserted into a stainless steel pipe 25 (first heating means) for circulating hot water.
FIG. 3 is an enlarged sectional view showing this state. In the figure, the stainless steel tube 25 is provided with insertion holes 25a that project obliquely upward at regular intervals, and the lower end 21a of the heat pipe 21 is inserted into the tube through the insertion holes 25a. A flange 25b formed at the end of the insertion hole 25a, and a flange 21 formed in the middle of the heat pipe 21.
b are joined, and the heat pipe 21 is fixed to the stainless steel tube 25. In addition, the eaves gutter 8 shown in Figure 1
A stainless steel pipe 26 is also installed inside the eaves gutter 8 to heat the eaves gutter 8. In addition, in Figure 2, 27
It is a rafter tree.

In such a configuration, when hot water is sent from a domestic boiler or the like to the stainless steel pipes 25 and 26, the heat pipe 21 absorbs the heat of the hot water and heats the colored iron plate, which is the roof finishing material, to melt snow. Water from melting snow is
It passes under the snow stopper 3, enters between the roof part 1a and the double roof part 5a, enters the eaves gutter 8, passes through the insulated pipe gutter 9 and downspout 10, and falls into the nearby storage tank 11. , drained into the side gutter (sewage) 12.

In this case, the melted snow water is transferred to the stainless steel pipe 2.
5, 26, the gutter 9, 10 immediately enters the eaves gutter 8 and is shielded from the outside air.
Because it is discharged through the air, it will not freeze on contact with the outside air. Furthermore, snow falling on the roof is immediately melted by the heat from the heat pipe 21, so snow does not accumulate on the roof 1.

In addition, in the above embodiment, the stainless steel pipe 2
Although hot water is passed through No. 5, the invention is not limited to this. For example, instead of hot water, a sheath heater may be passed through the stainless steel tube 25 to warm the inside of the stainless steel tube 25. Alternatively, the waste heat of the boiler may be guided to the heat pipe 21, thereby warming the heat pipe 21 and the cover portion 5, thereby making effective use of the waste heat.

[Effects of the invention] As explained above, this invention consists of a snow stopper installed horizontally on the roof, and a cover attached to cover the roof and eaves gutters below the snow stopper from above. Since it includes a first heating means for heating the inside of the covering part, and a second heating means for heating the roof, the following effects can be achieved.

(1) There is no need for snow removal.

(2) Icicle formation rarely occurs.

(3) There is almost no chance of leakage.

(4) Almost no ice formations are observed at the lower end of the roof. (5) Wasteful consumption of artificial energy will be eliminated.

(6) It can be easily installed on the roof of an existing building (roof of an existing building) without requiring large-scale construction work.
