Description

[Detailed description of the invention] This invention relates to a roof that uses indoor heating waste heat to melt snow on the roof.

In snowy areas, it is important to remove snow from roofs. For this purpose, there is a method of guiding and storing heating waste heat in the attic, a method of installing an electric field in the roof eaves where ice is formed, a method of sprinkling water on the roof, and a method of spreading tent cloth on the roof and applying vibration to the cloth. Various methods have been tried. When heat is applied to the roof shingles, the snow on the roof melts and flows down to the eaves.In order to prevent the snow from falling all at once and invading neighboring houses, metal fittings called snow stoppers are installed on the eaves of roofs in snowy areas. Since the snow in that area has frozen, the water that has melted and flowed down collects in the frozen area and leaks into the attic, causing what is called a leak. Furthermore, water droplets form and adhere to the attic panels, forming dew condensation and causing the phenomenon of aging of the ceiling panels. Therefore, it is not desirable to apply heat to the roof shingles. Furthermore, in the downspout that guides melt water on the roof, water that flows into the same type freezes at the upper end and hangs down like an icicle, and the drain function is lost in the winter.

Therefore, this idea was created by installing a simple roof for snow accumulation on top of the conventional roof, that is, forming a double roof, surrounding it with standing walls, and providing heating waste heat to the roof panels for snow accumulation. The purpose is to provide a roof in which water from melting snow can be drained without accumulating, condensation does not occur in the conventional attic, and there is no leakage and there is no need for snow removal work.

To explain an example, a general roof 2 installed over a room 1 has an eaves removed, and a roof board 3 for snow accumulation is provided on top of the roof 2 with legs 4 covering the entire surface of the roof 2. . As shown in FIG. 2, the roof board 3 for snow accumulation is a metal plate with corrugated edges, and small holes 7 for drainage are bored in the bottom surface 5 and side surfaces 6 thereof. The general roof 2 is one that is covered with metal plate roofing sheets that are widely used in snowy regions, and the snow-covering roofing sheets 3 are supported by connecting legs 4 to the snow-stopping angles 8 described above. . The roof board 3 extends by the length of the eaves that is missing from the general roof 2, and a standing wall 11 is provided between the standing pillars 10 that are connected to the outer pillars 9 of the house in contact with its peripheral edge. Therefore, the roof 2 and the roof shingle 3 are surrounded by a standing wall 11, and a space 13 covered with the snow roof shingle 3 is formed between the edge 12 of the general roof 2 and the standing wall 11. , the space 13 is also bent from the edge 12 of the general roof 2 to form a groove and a standing wall 1
The bottom is covered by a concave groove 14 of a metal plate raised along 1. The exhaust heat from the heater 15 in the room 1 is discharged outdoors through the chimney 16, and then guided through the vertical wall 11 onto the groove 14. The leading tube 1
7 is a metal fitting 18 supported on the edge 12 of a general roof
It is provided along the bottom surface of the snow roof board 3. The conduit 17 has a hole for exhaust, and the other end is blind. The groove 14 is inclined somewhat toward one end and communicates with a drainage gutter 19 at the other end, and the gutter 19 is surrounded by a heat insulating material 20 along the outer column 9 and communicates with the drainage groove. In the figure, 21 is a decorative material. The roof 2 of the embodiment can also be a single-slope roof.
Moreover, the snow-covering roof board 3 can be replaced with a normal corrugated iron plate instead of the large wave corrugated iron plate shown in the illustrated example.

According to the above configuration, a large space is formed on the general roof 2 surrounded by the snow-covering roof board 3, the standing walls 11 on the four sides, and the groove 14, so that exhaust heat from heating accumulates, and the snow-covering roof board Heats 3 efficiently. The snowmelt water flows downstream from the small hole 7 and is drained from the groove 14 by the drainage gutter 19. At this time, the drain gutter 19 is heated by the exhaust heat in the space 13 and is insulated below that temperature, so it does not freeze. Furthermore, this idea
It is a very practical idea, as it has the effect of being able to be carried out by using the air, and in the summer, room 1 is cool due to insulation, and water tanks for solar heating can be installed in the spaces on both roofs 2 and 3, so it can be used. There is a side. In addition, by passing the heating exhaust gas through a heat exchanger and using the secondarily warmed air heat, it is possible to prevent corrosion of the snow-melting roofing material of this invention and also prevent the occurrence of fires. It can be prevented.
