Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roof snow extinguishing device that discharges heat within a building directly from the roof surface and applies this heat directly to snow on the roof surface to eliminate snow. It is something.

[Conventional technology]

In Niigata Prefecture, an area with heavy snowfall, various roof snow removal devices have been developed.

The main types of snow melting equipment include those that use sprinklers such as water nozzles and pipes on the roof to melt snow, and those that heat the attic using heaters, hot air, exhaust, etc. to melt snow. The former has the disadvantage that the roof is easily damaged and is not durable, and water leaks when the roof freezes, while the latter has poor snow removal efficiency because the heat does not directly hit the snow, and is less efficient in the case of heavy snow. Ta.

[Problem to be solved by the invention]

The present invention solves this problem by providing a large number of exhaust pipes protruding from the entire surface of the roof, discharging the heat inside the building through the heat exhaust pipes, and directing this waste heat to the snow, which is highly efficient. It is a technical challenge to provide a roof snow removal device capable of removing snow.

[Means to solve the problem]

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

A heat exhaust pipe 3 that discharges heat from the building 2 to the entire surface of the roof 1
are protruded almost uniformly, and a heat exhaust gap 4 for discharging the heat inside the building 2 to the outside is provided at the upper end opening of the heat exhaust tube 3, and a cap 5 for preventing snow fall is fitted over the upper opening of the heat exhaust tube 3 to dissipate the heat. A roof snow removal device characterized by discharging heat inside a building 2 to the outside through a gap 4, introducing it to the snow 6 on the roof 1, melting the snow 6 from the inside to the outside, and extinguishing the snow. This is related.

[Effect]

The heat inside the building 2 is exhausted from the heat exhaust tube 3 to the outside through the heat exhaust gap 4, and the snow on the roof 1 is melted from the inside to the outside by this exhaust heat.

〔Example〕

The drawing shows the case where the present invention is applied to a long tile rod galvanized roof with a gable. Heat exhaust pipes 3 are formed protruding at regular intervals in the slope direction and the ridge direction. In the case of small heat exhaust cylinders 3, it is preferable to provide them with close intervals.

Although this heat exhaust tube 3 is formed by raising the edge of the heat exhaust hole 7, a heat exhaust tube 3 made of an FRP board may be attached.

The snow falling prevention cap 5 shown in FIG. 3 has a double peripheral wall, and heat exhausting notches 8 and 9 are provided at several locations on the inner wall 5a and at several locations on the heat exhaust tube 3 to create a heat discharging gap 4. is forming.

Figure 4 shows the snow fall prevention cap 5 and the heat exhaust pipe 3.
This is a case in which the heat exhaust gap 4 is formed by mounting slightly above the upper edge, and 10 is a mounting metal fitting.

This snow fall prevention cap 5 is made of galvanized iron plate.
It is best to make it from FRP etc.

11 in the figure is a snow stopper angle material. This snow stopper angle member 11 prevents a snow load from being applied to the heat exhaust pipe 3.

〔Effect of the invention〕

Since the present invention is configured as described above, this heat exhaust pipe 3
The heat inside the building 2 is discharged, and this waste heat is directly introduced into the snow 6, and the direct heat hits the snow 6, melting the snow 6 sequentially from the inside to the outside. Since snow is melted while storing exhaust heat in a cavity formed inside the snow pile 6 without letting it escape to the outside, thermal energy is not wasted, and a snow melting device having a correspondingly large snow melting ability is provided.

This thermal energy is economical because it uses the natural exhaust heat inside the building 2 (indoors), and it is also a snow removal system that stores the exhaust heat in the cavity and applies the thermal energy directly to the snow, so it does not change the outside temperature. This exhaust heat is sufficient because it does not depend on snow, but if the snow removal ability is reduced due to severe cold or heavy snowfall, more effective snow removal can be achieved by using an extra heater.

By creating a roof structure in which this exhaust heat causes convection, by considering the diameter of the heat exhaust tube 3, and by considering how to attach the heat exhaust tube 3, a more efficient snow removal device can be expected.

In addition, since the upper part of the heat exhaust cylinder 3 is covered with the snow fall prevention cap 5, snow does not get in, and since the snow fall prevention cap 5 is also heated, snow can be melted even at the snow fall prevention cap 5. Furthermore, since the upper part of the heat exhaust pipe 3 protrudes from the surface of the roof, melt water is prevented from flowing back into the heat exhaust pipe 3.

In this way, the present invention has become an unprecedented roof snow removal device, and in the summer, indoor heat is released from this heat exhaust pipe 3, and conversely, outside air is introduced indoors, so that indoor heat is In addition to being expected to have the effect of lowering the temperature, this device also has a heat exhaust pipe 3 that protrudes from the roof.
Since the roof has a simple structure by simply installing a snow fall prevention cap 5 above, it has excellent features such as being able to be installed on wooden buildings, reinforced steel buildings, and newly constructed and existing RC buildings.
