Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a roof snow extinguishing device that melts snow by emitting exhaust heat inside a building directly from the roof surface.

[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 with heaters, hot air, and exhaust heat 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 shine directly on the snow, and is less effective in the case of heavy snow. there were.

[Problem that the invention seeks to solve]

The present invention solves this problem by installing a large number of heat exhaust pipes protruding from the roof surface, discharging the waste heat from inside the building through the heat exhaust pipes, and directly applying this waste heat to the snowfall, resulting in an efficient and effective method. It is a technical challenge to provide a roof snow removal device capable of removing snow.

[Means for solving problems]

A heat exhaust pipe 3 is provided almost uniformly over the entire surface of the roof surface 1 and slightly protrudes from the roof surface 1 through which the waste heat inside the building 2 is discharged, and a heat exhaust path forming cover 4 is provided above the heat exhaust pipe 3. and a heat exhaust path 5 formed by the heat exhaust path forming cover 4 and the roof surface 1.
Therefore, the exhaust heat inside the building 2 is discharged from the heat exhaust pipe 3, and introduced into the snow 6 on the roof surface 1 through the heat exhaust path 5, melting the snow 6 from the inside and extinguishing the snow.

〔Example〕

Figure 1 shows a long tile rod tin roof with a gable, and heat exhaust pipes 3 are installed vertically at every other tile rod 7 in four locations in the slope direction, but the diameter is small. The heat exhaust pipes 3 may be provided closely spaced between the tile rods 7.

This heat exhaust cylinder 3 is formed by raising the twisted edge of the heat exhaust hole.

This heat exhaust path forming cover 4 is made of temporary FRP, galvanized iron plate,
A mouth-shaped board material such as a wooden board is used, and this "shaped board material is made parallel to the ridge and fixed to the snow stopper angle material 9 via the mounting bracket 8. Also, a partition plate 10 is provided on the tile bar 7m, and this partition plate 10 Exhaust heat dispersion holes 11 are bored to disperse exhaust heat in the left and right directions.

Figure 5 shows a roof made of wood wool cement board, with a heat exhaust tube 3 installed vertically on the heat exhaust hole hill, and above which the heat exhaust hole portion is covered with a single heat exhaust path forming cover 4. . (This heat exhaust path forming cover 4 is also fixed to the snow stop angle member 9 via the mounting bracket 8.) This heat exhaust path forming cover 4 has left and right walls and a rear wall, and the left and right walls also have exhaust holes. Heat dispersion holes 11 are bored.

In the above embodiments, the heat exhaust path 5 is directed toward the ridge, but it may also be directed toward the needle.

〔Effect of the invention〕

Since the present invention is configured as described above, the exhaust heat inside the building 2 is exhausted from the heat exhaust pipe 3, and this exhaust heat is transferred to the exhaust heat path forming cover 4.
Exhaust heat is directly introduced into the snow pile 6 from the tip of the heat exhaust passage 5 formed on the roof surface 1 and melts the snow pile 6 sequentially from the inside to the outside. Since this is a method of extinguishing snow while constantly stocking exhaust heat in the cavity formed in the snow, it is possible to provide a snow extinguishing device with a large extinguishing power.

This thermal energy uses the natural exhaust heat inside building 2 (indoors), but since it is a snow removal system that stores the exhaust heat in the cavity and applies the thermal energy directly to the snow, it is not affected by the outside temperature. Therefore, exhaust heat is sufficient, but if the snow-melting ability decreases due to severe cold or heavy snowfall, this can be solved by using an extra heater, which is economical and does not require much expense.

The roof structure is designed so that this waste heat causes a convection phenomenon,
By considering the way to open the heat exhaust hole U, the shape of the heat exhaust path forming cover 4, and the way to attach it, a more efficient snow removal device is expected.

In addition, since the upper part of this exhaust heat vi3 is covered with the exhaust heat path forming cover 4, snow does not get in, and since the exhaust heat path forming cover 4 is also heated, snow can be melted even in the area of the exhaust heat path forming cover 4. Since the upper part of this heat exhaust pipe 3 also slightly protrudes from the roof surface 1, melt water is prevented from flowing back into the heat exhaust hole.

In this way, the present invention has become an unprecedented roof snow removal device, and in the summer, indoor exhaust heat is released from this heat exhaust pipe 3, and on the other hand, outside air enters, so that the indoor temperature is reduced. In addition to being expected to have the effect of reducing It has excellent features such as being able to be installed on both new and existing RC buildings as well as new and existing RC buildings.
