Description

[Detailed description of the invention] This invention relates to a solar heat-collecting glass tile roof.

Conventional roof-mounted solar water heaters are not only unsightly, but also unstable in the face of wind and earthquakes. A type of solar water heater that is built into the roof has been proposed as a solution to these problems; Since the entire roof structure is changed to one that does not use tiles, aesthetic problems still remain.

The present invention is a completely new solar heat-collecting glass tile roof that solves all of these drawbacks. A heat collecting plate is placed under the glass tile, and the heat collecting plate is heated by sunlight passing through the glass tile.The glass tile is characterized by a shape particularly suitable for a solar heat collecting roof. do.

Next, embodiments of the present invention will be described according to embodiments shown in the drawings. Figure 1 is an explanatory diagram of the roof according to the present invention, where the plain tiles are the heat-collecting glass tile roof made of glass tiles, and the spot tile parts are the roof made of ordinary tiles. In this invention, the glass tile roof section can be freely installed in the required area at a selected location on a conventional roof. That is, the tiles of the heat collecting glass roof portion are made of glass tiles having substantially the same size and shape as ordinary tiles, and the heat collecting plate is placed under the glass tiles.

Figure 2 is a cross-sectional view of such a glass tile roof (the first
(A-A section) in the figure. In the figure, 1 is a glass tile, 2 is a regular tile, 3 is a heat collecting plate, 4 is a roof plate, and 5 is a tile beam. The tile beams 5 are installed directly on the roof board 4 or after laying waterproof paper. in this case,
The spacing is selected according to the length of the tile used,
There is no particular reason to change the height of the tile crosspiece 5 from the roof plate of the ordinary tile 2; in addition to securing the upper part of the glass tile 1, it also functions as a pillow for the glass tile, and the heat collecting plate 3 is placed between the roof plate 4 and the roof plate 4. It is only necessary to obtain a space for arranging the .

The glass tile 1 and the ordinary tile 2 differ only in their materials, and are substantially the same in shape and size. Therefore, when the ordinary tile 2 is a Japanese tile, the shape of the glass tile 1 is also the same as that of a Japanese tile.
Its shape can be selected as appropriate.

FIG. 3 is an enlarged view of such a glass tile 1. The glass tile 1 is molded from molten glass, and in this case, the glass has a high transmittance to sunlight and is resistant to thermal shock, such as borosilicate glass, which has a low iron content and a coefficient of linear expansion. A small one is suitable.

As shown in FIG. 4, the upper edge of the glass tile 1 is formed with a downwardly protruding edge 6 for locking to the roof plate 5 and an upwardly directed drainage weir 7, and the lower edge is formed with a downwardly directed drainage weir. A weir 8 is formed. In this case, for the above-mentioned purpose, it is sufficient to provide the protruding edge 6 at a part of the upper edge, for example, at a location where the lower surface of the glass tile 1 contacts the roof board 5, but it is sufficient to provide the protruding edge 6 at a portion of the upper edge, for example, at a location where the lower surface of the glass tile 1 contacts the roof board 5. are formed so as to extend over substantially the entire area of the upper and lower edges, respectively.

In the present invention, when the upward weir 7 and the downward weir 8 of these glass tiles constitute a heat collecting glass tile roof,
The heat collecting efficiency of the heat collecting plate 3 disposed under the glass tile 1 is designed to be as high as possible. That is,
When overlapping the upper weir and the lower weir and stacking glass tiles, these weirs are formed so that even if the overlapping portion of both is as small as possible, intrusion due to backflow of rainwater does not occur.
This is because the larger the overlapped portion of the glass tiles, the lower the heat transmittance.

On the other hand, the height a of the upward weir 7 provided on the upper edge of the glass tile 1 is made larger than the height b of the downward weir 8 on the lower edge, and these two weirs are overlapped as shown in FIG. When the glass tiles are stacked one on top of the other, the lower upward weir 7 comes into close contact with the lower surface of the upper tile to prevent rainwater from entering. Furthermore, in order to further ensure the intrusion of rainwater, a space A is formed between these two weirs. If a predetermined space A is formed between the two weirs, even if rainwater enters from below the downward weir 8, it can remain in this space, so that it functions effectively as an escape area for the intruding rainwater. Therefore, this space A
Although the size of is not specified, it is undesirable if it is extremely small. Further, the wall surface of the upward weir 7 facing the space A may be made as perpendicular to the top surface of the glass tile 1 as possible to prevent rainwater from entering the interior beyond the upward weir 7. It's important.

Note that the heat collecting plate 3 is disposed on the roof plate below the glass tile 1 via a heat insulating material or with a space between them. Although the details of this heat collecting plate 3 are omitted, it is equipped with a thin tube body that conducts a heat medium, and is disposed laterally in the area between the tile beams 5, and the solar rays projected from the glass tile 1 The heating medium is heated.

Since the present invention is constructed as described above, it is possible to obtain a heat-collecting glass tile roof that is integrated into a normal tile roof, which not only has an aesthetically pleasing appearance but also has safety against wind and earthquakes. In addition to having good properties and stability, the draining shape of the glass tiles prevents rainwater from entering and improves solar heat absorption efficiency.
