Description

[Detailed Description of the Invention] This invention relates to a structure for attaching a so-called roof-integrated solar heat collector to a roof, in which a plurality of solar heat collectors are fixed to a roof base material so as to serve as roof plates.

Various roof-mounting structures have been proposed for roof-integrated solar heat collectors, but all of them not only require complicated structures to maintain watertightness, but also lack sufficient strength. Therefore, it is particularly unsuitable for application to the roofs of ordinary houses, and further problems remain when applied to existing roofs.

This proposal eliminates the drawbacks of the conventional method and is designed to ensure sufficient watertightness between adjacent heat collectors when multiple heat collectors are installed adjacently. The details of this proposal will be explained with reference to this document.

For example, the water supply pipe 22 and the hot water take-out pipe 23 that supply water to the triple heat collectors are connected to the lowest heat collector 4.
and the nozzle 8' of the uppermost heat collector 4, and extend to a predetermined position along the roof. In this case, the water supply pipe 22 and the hot water outlet pipe 23 are preferably arranged within the interval between the adjacent support frames 3, 3. In addition, the nozzle 7' of the lowest heat collector and the nozzle 8' of the top heat collector are pulled out from inside each heat collector case 5 through the case bottom plate 24 and into the support frame 3, and then the roof plate 2 It may also be guided through the attic to the attic.

Adjacent heat collectors 4, 4 in the above triple heat collector
Between the spaces = A horizontal gutter B is provided under S, and the horizontal gutter B
has a channel-shaped gutter body 41 that is slightly longer than the left and right width of the outer frame of the support frame 3 and slightly shorter than the interval between the left and right hanging plates 11, 11 of the heat collector 4;
Two locking strips 42, 42 having a hook-like cross section are protruded from a mounting plate extending from one side of the heat collector. 35
The gutter body 41 is secured to the
The gutter body 41 is extended horizontally between the heat collector and the support frame 3 in a state that it matches the lower opening of the gutter body 41.
The vertical frame 1 of the support frame 3 is connected to both open ends of the
3 and 13 and hanging plates 11 and 11. 43 is an elastic tight material such as rubber pushed into the upper opening of the spacer S (Fig. 3), and 44 is a drain hole formed by cutting out the middle part of the tight material 19, 19 of the left and right hanging plates 11, 11. (Figure 3). In this way, the rainwater that has entered the space S falls into the horizontal gutter B, and flows through the horizontal gutter B from the open end to the tight material 19 between the support frame 3 and the left and right hanging plates 11, 11. , 19, and is discharged to the outside from the drain port 44 of the tight material.

Note that the left and right openings of the space S and the space between the adjacent hanging plates 11, 11 may also be closed with a suitable watertight material such as a tight material or a sealing material. However, in some cases, the upper and left and right openings of the spacer S may be left open.

In addition, the drainage port 44 of the tight material 19 is connected to the tight material 1 of the hanging plate on the lower side of the roof slope in the lowest heat collector.

A fourth heat collector is installed on the uppermost side of the three heat collectors in the roof slope direction.
As shown in the figure, a rain cover 45 is provided, and the rain cover 45 is a rectangular plate with approximately the same width as the left and right width of the heat collector 4, and one end thereof is fixed to the upper wall of the uppermost heat collector 4. The cover is extended obliquely to the upper roof surface, the upper end of the cover is similarly extended over the extended part 16 of the flashing board 15, and the upper end is bent into a backsplash 46 and overlapped under the roof board P. There is. The means for fixing one end of the cover 45 to the heat collector includes, as shown in the fourth figure, a supporting plate 47 having an upward hook-shaped cross section that extends over the entire length of the hanging plate 11 and protrudes from the outer surface of the hanging plate 11 body. It has a structure in which one end of a cover 45 is folded over from above and secured with rivets 48 to the upward end of the support plate. In this way, rainwater flowing down the roof surface from above the heat collector is distributed to the left and right from above the rain restraint cover 45 and flows to the right and left sides of the heat collector 4, and the support frame 4
There is no accumulation on the outside of the upper horizontal frame 14. This prevents rainwater from concentrating on the outside of the upper horizontal frame 14 and overflowing from the upper horizontal frame 14 into the frame during heavy rain.

The slope of the flashing cover 45 is preferably set to be appropriately sloped downward from the horizontal plane toward the lower side of the roof slope.

In this case, except for horizontal gutter B in the above example,
It is also possible to support the heat collectors 4 with their bottom surfaces in contact with the top surface of the support frame 3.

It goes without saying that the above example can also be applied to the roof mounting structure of a solar heat collector using air as a heat medium.

The structure for mounting the solar heat collector on the roof of this invention has an extremely simple structure in which the collector is supported on a frame-shaped support frame fixed to the roof base material, yet it is able to ensure sufficient watertightness. In addition, it can firmly support the heat collector, and therefore, it can be easily installed not only on newly built roofs but also on existing roofs, and in particular, can be easily installed on the roofs of ordinary houses.
Furthermore, according to the present invention, it is possible to maintain watertightness between a plurality of adjacent heat collectors by the horizontal gutter, thereby making it easy to support a plurality of heat collectors in a watertight manner on one support frame. be.
