Description

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

[Conventional technology]

Conventionally, sprinkler type, electric heater type, and hot water pipe type are known as this type of roof snow melting device.

[Problem that the invention seeks to solve]

However, all of these methods have disadvantages in that they are uneconomical due to high construction costs and maintenance and operation costs, and are unsatisfactory in terms of snow melting effect.

[Means for solving problems]

The purpose of the present invention is to solve these inconveniences.The gist of the present invention is to form a snow-melting roof plate, which serves as a roofing material for a building, from a folded metal roofing material, and to connect the snow-melting roof plate to a ceiling wall. In a roof snow melting device that melts accumulated snow on a snow melting roof board by warm air introduced indoors during the period of warm air introduction, the snow melting roof board is provided with an upright structure on the outer circumference of the snow melting roof board of the building that protrudes upward from the upper surface of the snow melting roof board. A roof snow melting device is characterized in that it is configured by arranging a wall portion.

[Effect]

Introducing warm air The warm air inside the room melts the snow on the snow-melting roof panels made of folded roofing materials, and the standing walls located on the outside cool the snow on the snow-melting roof panels and freeze them. can be suppressed.

〔Example〕

1 and 2 show an embodiment of the invention.

The snow-melting roof board 1 is made of a material that has the strength to withstand snow loads in snowy areas, has good thermal conductivity, and has a condensation adsorption material attached to the back side. Large cross-section corrugated roofs) are preferred.

A commercially available folded roof roof with a height of 17 cm and a pitch of 30 cm is said to be able to withstand approximately 2 m of snow.

A rising wall 2 of an appropriate height is provided around the outer circumference of the snow-melting roof board 1 to protrude upward from the upper surface of the snow-melting roof board 1 to prevent accumulated snow from freezing as it is cooled by outside air from the sides. do.

A warm air introduction chamber 4 is provided between the snow melting roof board 1 and the ceiling wall 3.

It is desirable to lay a heat insulating material 5 on the upper surface of the ceiling wall 3.

Warm air is introduced into this warm air introduction chamber 4.

This introduction may take advantage of the rise of the warm air and may be introduced naturally or may be forcibly introduced from the warm air introduction port 7 using the introduction fan 6.

The introduced warm air melts the snow on the snow-melting roof board 1, and the cold air after heat exchange is forcibly exhausted from the forced exhaust hole 8 using an exhaust fan 9.

In the case of a two-story house or more, an atrium 10 or a communication hole 11 is provided to guide warm air sequentially from the lower floor to the upper floor.

A water drop adsorbing material 13 for adsorbing water droplets condensed on the top and bottom of the folded roof 12 is adhered to the back surface of the folded roof 12 to prevent the condensation from falling due to its water supply action.

In particular, since the water drop adsorbing material 13 provided on the back surface of the valley bottom is dried by warm air, it adsorbs dew condensation better and prevents it from dripping onto the ceiling wall 3.

In addition, snowmelt water is collected in the meltwater gutter 14, and this meltwater gutter 1
A drain pipe 15 is installed vertically at the drain pipe 15, and it is desirable to place this drain pipe 15 indoors so that the melt water flowing down therein does not freeze. It is necessary to wrap the roof with insulation to prevent water from freezing or forming into icicles.

It is desirable that the melt water gutter 14 is also placed close to the warm air introduction chamber 4 so that it can be heated with warm air.

In the figure, 16 is a sewage pipe, and 17 is a sewage ditch.

The present invention provides heaters 18 used on each floor (for example, a stove 18' on the first floor, a kotatsu 1 on the second floor,
8'') is guided to the top floor through the atrium 10 and the communication hole 11,
The hot air is introduced into the warm air introduction chamber 4 by natural rise due to convection.

This warm air is forcibly exhausted from the forced exhaust hole 8 by the exhaust fan 9, but during that time, the introduced warm air exchanges heat through the snow melting roof board 1 made of a material with good thermal conductivity, and the snow accumulation on the snow melting roof board 1 is carried out. It will melt more and more.

This snow-melting roof board 1 itself can sufficiently withstand the snow load, and since snowfall does not last for many days, even if the amount of snowfall exceeds the amount that is temporarily melted, only the snow-melting action will be performed once the snowfall stops. The snow gradually melts from the lower layer, reducing the amount of snow, and if care is taken to ensure smooth drainage, there will be no need to remove the snow at all.

Of course, it is natural to think that in order to melt snow, a heat source is necessary to melt it, but the present invention takes a leap forward from this natural way of thinking and directs only the residual heat of the warm air used indoors to the attic. By taking the following precautions, which we had not noticed until now, we are trying to melt the snow using only this residual heat.

For this purpose, the first step is to use snow-melting roof panels such as metal folded roofs.

Next, warm exhaust air is guided to the underside of this snow melting roof board,
This hot exhaust melts the snow on the snow melting roof board, and the cold air after heat exchange is promptly discharged from the forced exhaust hole 8, and at the same time prevents outside air from entering the warm air introduction room through the forced exhaust hole 8. This is the point.

With this consideration, the accumulated snow on the snow melting roof board can be sufficiently melted by simply collecting warm indoor air in the attic without preparing a special heat source for snow melting, and also consideration is given to quickly draining this snow melting water. As a result, even if the snow accumulates, using heating indoors will gradually increase the snow melting effect, and as the weather gets better, the snow melting effect will become even better, eventually making it unnecessary to remove the snow, such as in Tokamachi City. It has been proven that even in areas with heavy snowfall, it is possible to remove the snow even once.

The inventor adopted the snow melting method of the present invention in a three-story office, installed kerosene stoves on the first, second, and third floors, and used it as a normal office from 1974 to 1972.
During the winter of 2017, I had to remove the snow from the 5th floor roof of a nearby private house, but my office didn't have to remove the snow even once, and the amount of snow was 1.
It never exceeded m.

In other words, I don't use the stove at all because I work at the office at night and in the morning and evening, but I can get a good snow melting effect even if I use the stove during daytime office hours without having to remove the snow enough. It was.

In particular, since a rising wall portion 2 that protrudes upward from the upper surface of the snow melting roof sheet 1 is provided around the outer circumference of the snow melting roof sheet 1 of the building, the presence of the rising wall portion 2 causes the snow melting roof sheet 1 to rise. It is possible to prevent the snow from freezing due to being cooled by the outside air, and improve the snow melting effect.

Moreover, the roof of the present invention may be a normal folded roof, and the only special equipment required is to attach water droplet absorbing material to the underside of the attic and add a drainage device to prevent melt water from freezing. It would be a good idea to take this into consideration.

Therefore, unlike traditional snow melting methods, there is almost no equipment cost, and in addition, the most important heat source cost is that there is no need to fire a stove specifically for snow melting, making it extremely economical and completely cost-effective. It is no exaggeration to say that this is an innovative roof snow melting device that eliminates the need to remove snow.

In addition, by attaching a water droplet adsorbent to the back of the snow melting roof board and the forced removal of warm air, even if condensation occurs, it evaporates while it is adsorbed by the water droplet adsorbent and prevents dripping. In the summer, the room can be cooled by drawing air warmed by radiant heat from the warm air introduction room through the forced exhaust vents.

In addition, the roof snow melting device of the present invention will be more effective if used in a factory where a large amount of warm air can be obtained, but it will also have an excellent snow melting effect when used in an office, store, or general residence that uses heating. This is an excellent roof snow melting device that can be used for melting snow on arcades and other various types of snow melting using the warm air inside the store.

〔Effect of the invention〕

As described above, according to the present invention, the accumulated snow on the snow-melting roof board made of folded roofing material is melted by the warm air in the room where warm air is introduced, and the snow-melting roof board is melted by the rising wall portion located on the outer circumference of the snow-melting roof board. It is possible to prevent the snow from being cooled by the outside air and freezing, and the snow melting efficiency can be improved accordingly.
