Description

[Detailed Description of the Invention] The present invention relates to a snow melting roof, and more specifically, to a snow melting roof that can prevent snow from accumulating on the roof without requiring human effort by increasing the temperature of the roof surface.

Generally, in areas with heavy snowfall, snow removal work is performed manually to prevent damage to houses due to the weight of snow accumulated on roofs.

However, removing snow is extremely hard and dangerous work, and it must be repeated from time to time, so businesses and households alike have been burdened by this troublesome and complicated work. In particular, households without male workers or households with elderly people faced problems such as having to have workers on hand at all times.

Therefore, the purpose of this invention is to solve the above-mentioned problems of conventional roofs, and to eliminate the need for human or mechanical power.
To provide a snow-melting roof capable of melting accumulated snow on a roof surface with simple equipment.

That is, in the snow melting roof according to the present invention, a heat insulating material is laid between a metal roof plate and a roof base material, and a copper pipe for allowing a heat transfer fluid to flow through the upper layer of the heat insulating material is parallel to the surface of the roof plate. Along with piping to
The upper surface of the copper tube is configured to come into contact with the back surface of the roof board through an electrolytic corrosion prevention sheet.

Hereinafter, an embodiment of the snow melting roof according to the present invention will be described with reference to FIGS. 1 and 2.

Figure 1 shows a cross section between adjacent tile rods of a roof with tile rods, and there is a heat insulating material between the sheathing board 1 of the roof and a metal roofing board 6, such as a galvanized color iron sheet. For example, a hard urethane foam 2 is laid.

Grooves 3a, 3b, and 3c are formed on the upper surface of the heat insulating material 2 at regular intervals in the direction of the slope of the roof. These grooves are alternately connected to adjacent grooves at the ridge and eaves of the roof. For example, in the ridge part, adjacent grooves 3a and 3b are connected almost horizontally by a groove having the same cross section, and in the eave area, adjacent grooves 3b and 3c are connected almost horizontally by a groove having the same cross section. Because
The grooves 3a, 3b, and 3c form a single curved communication path on the upper surface of the heat insulating material.

Inside these communicating grooves 3a, 3b, and 3c, a single copper tube 4 having an oval cross-sectional shape is housed so as to meander and circulate above the heat insulating material along the grooves.

Further, as shown in detail in FIG. 2, the upper surface of the groove 3 is covered with an electrolytic corrosion prevention sheet, for example, an aluminum sheet 5, which is wider than the upper surface of the groove, and the upper surface of this aluminum sheet 5 is covered with a metal roofing plate. It is in close contact with the back side of 6. The upper surface of the copper tube 4 is covered with an aluminum sheet 5.
Since the upper surface of the copper tube 4 is in close contact with the lower surface of the metal roof plate 6, the upper surface of the copper pipe 4 comes into contact with the lower surface of the metal roof plate 6 via the aluminum sheet 5. This aluminum sheet 5 may be a stainless steel sheet.

Furthermore, the inlet and outlet of the copper tube 4 are connected to a heat exchanger (not shown), and the heat transfer fluid is heated by the heat exchanger, such as a fluid containing ethylene glycol as a main ingredient and additives added thereto. melts the snow by dissipating heat from the upper surface of the collar steel plate 6 through the aluminum sheet 5 while flowing along the groove 3 in the copper pipe, and the heat transfer fluid whose temperature has decreased is returned to the heat exchanger and heated, and this circulation This is becoming more and more common.
Although this embodiment describes a case in which piping is provided between adjacent tile rods, it goes without saying that one piping may be connected between a plurality of tile rods or for the entire roof.

As is clear from the above explanation, according to the present invention, the lower surface and both sides of the copper space in which the heat transfer fluid is circulated are surrounded by a heat insulating material, and the upper surface is covered with a metal attic through an aluminum sheet etc. with good heat conduction. Since it is in contact with the surface, it can efficiently maintain the metal roof surface above a certain temperature and melt snow, making it possible to prevent snow from accumulating on the roof without requiring dangerous manual labor. .

In addition, since a galvanic corrosion prevention sheet, such as an aluminum sheet or a stainless steel sheet, is interposed between the copper pipe and the metal roof sheet, it is possible to reliably prevent galvanic corrosion and ensure long-term use. I can do it.
