[Detailed description of the invention] This invention can efficiently melt roof snow using the heat of circulating hot water during the snow melting season, and efficiently absorb and utilize solar heat during the solar heat utilization season. The structure of a circulating pipe structure for a roof system capable of melting snow and utilizing solar heat will be described in detail as follows with reference to the accompanying drawings showing one embodiment.

A partition plate in which the roof of a building is formed of a folded roof 1 having a substantially wave-shaped cross section, and the valley bottom 2 of the folded roof 1 has water passage holes 4 at a predetermined interval above the valley bottom surface 3. The body 5 is suspended horizontally along the valley floor 2, and a circulation pipe 7 is disposed approximately in the center of the compartment 6 divided by the partition plate 5 and the valley floor 3, so that the circulation pipe 7 Then, hot water is circulated in the circulation pipe 7 to warm the air in the compartment 7, and the warm air melts the roof snow through the partition plate 5, and the melted snow water a flows through the water passage hole. 4, the snowmelt water flows down on the valley floor 3 to melt the snow, and during the solar heat utilization season, the snowmelt water flows through the circulation pipe 7.
Snow melting and solar heat by circulating water inside the compartment, warming the circulating water with the warm air in the compartment 6 heated by solar heat via the partition plate 5, and using the solar heat as the circulating water as hot water. In the dual-use roof device, the circulation pipe 7 is made of a material such as copper or aluminum, and the cross section of the circulation pipe 7 is formed into a flat shape with a small water passage area. This device is characterized in that a black film 7a is formed on the outer surface by applying black paint or the like.It will be described in more detail.

The folded roof 1 of the roofing device of this embodiment has a beam material 8 and a band-shaped evening frame 9 having substantially the same cross-sectional shape as the folded roof 1.
are fixed in parallel at several places, the folded roof 1 is placed on this tight frame 9, and the folded roof 1 is connected and fixed to the peak part 10 of the folded roof 1 by a connecting bolt 11 projecting upward.

Further, at each mountaintop 10, a snow shielding plate 13 is provided over the depth of the folded roof 1, separated by a predetermined distance from the upper surface and both slopes by spacing nuts 12, and the connecting bolts 11
Mounting plates 14 having approximately the same width as the tight frame 9 are attached to each mountain top 10, and the folded roof 1 and snow shielding plate 13 are attached to the tight frame 9 by connecting bolts 11, spacing nuts 12, and tightening nuts 15. - The mounting plate 14 is fixed, a warm air introduction chamber 16 is formed between the snow shielding plate 13 and the upper surface and both slopes of the folded roof 1, and upper and lower hooks are installed on both left and right sides of the mounting plate 14. A lower hooking piece 14b is formed on the piece 14a1, and a net-shaped partition plate body 5 extending over the depth of the folded roof 1 is hooked between the upper hooking piece 14a and the adjacent upper hooking piece 14a.
Only during the solar heat usage season, a reflective plate 17 spanning the depth of the folded roof 1 is hooked between the lower hook pieces 14b and the adjacent lower hook pieces 14b.

This reflective plate 17 has a galvanized iron plate 19 formed on the upper surface of a heat insulating material 18.

The circulation pipe 7 of this embodiment is made of a copper member, and its shape is such that both sides of the central part of a circular pipe are crushed to make the cross section flat, and the passage hole 20 is divided into left and right parts. This reduces the water flow area, and the outer surface of the circulation pipe 7 is coated with black paint to form a black film 7.
It forms a.

Since this embodiment has the above-mentioned configuration, during the snow melting season, the partition plate 5 is suspended between the upper hanging pieces 14a as shown in FIG. A snow-free compartment 6 is formed in the valley bottom 2 of the folded roof 1 due to snow accumulation, and the snow shielding plate 13 prevents warm air between the snow shielding plate 13 and the upper surface and both slopes of the folded roof 1. An introduction chamber 16 is formed, and when hot water is supplied and circulated in the circulation pipe 7 by a boiler or the like, the air in the compartment chamber 6 is warmed by the heat of the hot water, and the warmed air flows into the warm air introduction chamber 16. In this way, the snow on the partition plate 5 and the snow on the snow shield plate 13 are melted, and the melted snow water a flows into the water passage hole of the partition plate 5. 4 and flows down onto the valley bottom surface 3, where it is collected and discharged by the roof slope, where snow melting is performed.

In addition, during the solar heating season, as shown in Fig. 3, if the reflector plate 17 is placed under the circulation pipe 7 and suspended between the lower hanging pieces 14b, then the sunlight will not be directly transmitted. On the other hand, the snow shield plate 13
The light is reflected on the slope, concentrated on the valley bottom 2, indirectly enters the circulation pipe 7, is further reflected on the surface of the reflector 17, enters the circulation pipe 7, and is reflected in the compartment 6. The air is heated, and the circulation pipe 7 is heated by this warm air, etc., and when water is circulated in the circulation pipe 7, the circulating water is heated by the warm air, etc. in the compartment 6 and becomes hot water, and the hot water is heated by solar heat. You will get it.

Although the partition plate 5 of this embodiment has a net shape, it is also possible to use a plate with holes drilled therein to form the water passage holes 4, or a plate with holes formed in the side edges of the plate to form the water passage holes 4. It can also be applied to a material with cutout grooves formed therein.

As mentioned above in this invention, during the snow melting season, the circulation pipe 7
When hot water is circulated inside, the heat of the hot water causes the compartment chamber 6 to
The air inside the room will be warmed, and the snow will be melted by the warm air. Also, during the solar heating season, when water is circulated in the circulation pipe 7, the air inside the compartment 6 heated by solar heat will be heated. The circulating water in the circulation pipe 7 is heated by warm air, etc., and hot water is produced by solar heat. At this time, the circulation pipe 7 is formed of a material such as copper or aluminum, and the circulation pipe 7 is 7 has a flat cross-sectional shape with a small water-flowing area, which not only improves heat conduction, but also reduces the water-flowing area relative to the outer surface area compared to a circular cross-sectional shape. This means that during the solar heat utilization season, the solar heat absorption area is larger than the water passing area, which improves the solar heat utilization efficiency.Also, even during the snow melting season, the heat radiation efficiency is good, making it more efficient than the conventional method. Heat absorption and heat radiation efficiency can be improved compared to circular pipes.

Furthermore, since the black film 7a is formed on the outer surface of the circulation pipe 7 using black paint or the like, the heat absorption efficiency is further improved by the black film 7a.

As described above, according to the present invention, roof snow can be efficiently melted using the heat of circulating hot water during snow melting season, and solar heat can be efficiently absorbed and utilized during solar heat utilization season. The present invention provides a circulation pipe structure for a roof system that can be used for both snow melting and solar heat utilization, and has excellent practical effects such as:
