Description

[Detailed Description of the Invention] (Object of the Invention) This invention relates to a new structure for the eaves of a building in a snowy region, and is particularly aimed at eliminating damage caused by snow accumulating on the roof surface of a building during a snowy period. The purpose of this project is to provide a snow melting structure with a new structure that enables the following.

(Prior Art) In snowy regions such as the Hokuriku and Tohoku regions, the problem of snow disposal during the snowy period from December to March of the following year becomes a major social problem. One of these is the issue of how to deal with snow that accumulates on roofs.

The snow that accumulates on the roof usually stays at the eaves for a long time in the condition shown in Figure 2 of the drawing, so it is not only a problem as a load on the building, but also a problem due to the temperature and temperature. Individuals are concerned with administrative matters, such as the problems of "sugamore" and "icicles" that occur due to repeated snowfall, the problem of damage to property due to falling snow, and the problem of removing snow that accumulates on the ground due to snow removal and falling snow. They are also under great financial and psychological burden.

Reflecting this situation, recently, as shown schematically in Figure 1, a roof with a V-shaped cross section is formed, with the roof surface sloping downward toward the center, and snow is placed in the center of the roof. Buildings with "no-snow roof structures" have been implemented, which install drains to treat snowmelt water, and create a continuous space from the wall to the roof base to circulate warm air and prevent snow from accumulating on the roof surface. ``Air cycle architecture,'' which eliminates air pollution, has also been proposed and put into practical use.

However, in the former structure, the snow melting pipe passes vertically through the center of the building, which poses major problems such as restrictions on the floor plan and hindrance to repairs and inspections. It has not necessarily become as popular as expected due to problems in usage and exterior design, and the latter structure has the major disadvantage of being too expensive in terms of architectural structure. Due to reasons such as not having high expectations from the standpoint of snow efficiency, it has not yet reached the point where it is widely used.

In view of the above-mentioned circumstances, this invention has been developed and researched diligently for many years, and as a result, we have finally completed a snow melting structure for the eaves part that has a completely new structure as detailed below. It is ivy.

(Structure of the Invention) As clearly understood from the representative embodiment of the invention shown in FIG. This forms a reinforced snow-resistant eaves portion, and the eaves 4 is formed in the eaves portion so as to have an opposite slope to the slope of the main roof surface 10, while the boundary between the eaves 4 and the main roof surface 10 is The snow melting structure of the eaves part is formed by connecting the formed gutter 1 to a downpipe 3 which also serves as a blowing pipe for warm air 5 from a heat source as appropriate.

As shown in the figure, the eaves reinforcement beam 2 that is horizontally suspended on the eave girder or gable 20 is
Snow 15 is distributed in a well-balanced manner above, and falls from the main roof surface 10, is caught by the eaves 4 with a different slope, and remains accumulated on the eaves until it is forcibly melted. However, it is necessary to create a structure that is sufficiently designed to support the snow load without any problems.

In the figure, reference numeral 10 indicates snow accumulated on the roof surface, and reference numeral 16 indicates icicles hanging down from the eaves.

(Preferred Embodiment 1) FIG. 4 shows an enlarged longitudinal cross-section of essential parts to show the above-mentioned configuration in more detail.

As can be understood from this figure, the downspout 3, which is connected to the gutter 1 and also serves as a blowing pipe for warm air 5 from an appropriate heat source, functions as a normal rain gutter except during snowfall periods. While the lower end is guided to the drainage, a guide pipe for guiding the warm air 5 from the attic is connected to a suitable position below the gutter 1, in the example below the paving girder,
During the snowfall period, the warm air 5 that accumulates in the attic is forcibly sent in by the fan 6. Therefore, this downpipe 3 is used as a column during the snowfall period, a drain pipe for melting snow water, and a guide pipe for the warm air 5. It also serves as

In the figure, 9 is insulation material, 11 is under the eaves, 12 is the ceiling,
Reference numeral 13 indicates a wall, and reference numeral 14 indicates a floor.

(Preferred Embodiment 2) FIG. 4 also shows an embodiment in which a geothermal induction pipe 7 with a trap for inducing geothermal heat is connected to an appropriate position at the lower end of the downspout 3.

In this embodiment as well, the downspout 3 only functions as a rain gutter except during the snowfall period, but during the snowfall period, in addition to its function as a drainage pipe, the downspout 3 also functions as a drainpipe and drains natural water through the geothermal induction pipe 7 with a trap. It functions as a guide pipe that guides the warm air rising from the geothermal heat 8 to the gutter 1.

(Preferred Embodiment 3) As described above, the downspout 3 has two functions: one as a guide pipe that guides the heat source as the warm air 5 accumulated in the attic, and the other as a guide pipe that guides the warm air using the geothermal heat 8 as the heat source. In addition to being able to perform both functions independently, it is also possible to combine both functions as shown in the illustrated embodiment.

The snow melting structure for the eaves of the present invention, which has the above-mentioned basic structure, may be further added with the following structure.

That is, the lower end of the downspout 3 connected to the gutter 1 is connected to the drainage basin 17, and at the same time, the geothermal induction pipe 7 having a trap 18 is connected to a suitable position on the lower side of the downspout 3.

The tip of the downspout 3 connected to the drainage basin 17 should be carefully positioned so that it is always located below the water surface to prevent cold air from flowing back.

The trap 18 in the trap-equipped geothermal induction pipe 7 is adopted for the purpose of preventing falling snowmelt water from flowing back into the guide pipe 7 and reducing the geothermal heat.

On the other hand, the downspout 3 in the snow melting structure of the eaves of the present invention is arranged with a heat insulating material 9 etc. on its outer periphery so that the warm air from the heat source can be appropriately guided to the gutter 1 without waste. It is advantageous to realize an upper insulating structure.

(Operation and Effect) In the snow melting structure of the eaves part of the present invention having the above-described configuration, a snow-resistant eave part reinforced by combining the eaves reinforcement beams 2 on the eave beams or end beams 20 is formed, and the roof In addition to realizing a structure that can sufficiently withstand even if the snow 15 that accumulates on the surface stays in the same place temporarily, it is also possible to forcibly use warm air 5 from the surplus heat source in the attic or warm air from the geothermal heat 8. Since it can melt snow, it is possible to eliminate various problems caused by falling snow from the roof surface at once. It has a simple structure that requires only a combination of the above and the slope of the eaves, and the downspout 3 can be placed on the outer wall, making it extremely economical. .

In addition, since it is possible to achieve a significantly different appearance from the exterior of the building in conjunction with the main roof surface 10, it is superior in terms of design compared to conventional ones, and is advantageous in terms of popularization. Become.

In addition, because the heat source for snow melting can be effectively used alone or in combination with surplus heat in the attic or geothermal heat8, there is almost no need to spend money on snow melting, and there is no need to spend money on snow melting, which would otherwise be expensive. This will be very advantageous for the lives of the people in the area.

On the other hand, connect the lower end of the downspout 3 to the drainage basin 17,
In the case of a structure that has a trap 18 at the appropriate location on the lower end side, cold air from the outside may flow backwards,
Since the snowmelt water does not flow back into the ground, there is very little risk that the heat of the warm air guided to the gutter 1 will be cooled down.

This effect becomes even more remarkable in the case where the outer periphery of the downspout 3 has an insulating structure for heat conduction.

As mentioned above, the snow melting structure of the eaves of this invention functions extremely effectively and economically in melting snow in buildings located in snowy regions, and is also excellent in terms of design, regardless of whether it is used outside, newly built, or renovated. Since it also has the characteristic of being employable,
This makes it possible to realize an almost ideal snow melting structure.
