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 configured to ensure sufficient watertightness between each heat collector when multiple heat collectors are installed.
The details of the present invention will be explained below with reference to the drawings.

In Figure 1, rafters 1...
are supported in parallel, and the sheathing board 2 is stretched over the rafters 1..., and at the same time, waterproof paper is laid on the sheathing board or not (in this example, waterproof paper is not laid) to form a roof base. On this base, heat collector support frames 3, which are in the form of a vertically long frame that spans the entire length of the roof slope and have an appropriate height rising above the roof surface, are fixed in parallel with each other at small intervals in the left and right direction. On each support frame 3, three flat plate type solar heat collectors 4 are supported adjacently in the roof inclination direction to form a triple heat collector.

As shown in Figures 3, 4, and 5, in this example, the solar heat collector 4 has a flat top surface of a flat box-shaped case 5 open, and a transparent glass 6 is fitted therein in a watertight manner, and a water supply is provided inside the case 5. In addition to installing a lower header pipe 7 for hot water and an upper header pipe 8 for taking out hot water, a large number of channels 10 through which hot water flows between both header pipes 7 and 8 are installed.
A heat collecting plate 9 having a heat collector case 5 is connected, and one end of each lower and upper header pipe 7, 8 is used as a lower and upper header pipe nozzle 7', 8' to penetrate the left and right side walls of the heat collector case 5 and protrude to the outside. In this case, as shown in the second figure, in the lowest and highest heat collectors among the three heat collectors, the lower header pipe nozzle 7' projects to the left, and the upper header pipe nozzle 8' projects to the right. At the same time, in the middle heat collector, the lower header pipe nozzle 7' projects to the right and the upper header pipe nozzle 8' projects to the left. Suspended plates 11 of appropriate lengths connected to each other are extended downward from the side walls, and hanging plates 11 connected to each other are extended downward from the left and right side walls and the upper side wall of the case 5 of the uppermost heat collector. Also, hang down plates 1 from the left and right side walls of case 5 of the intermediate heat collector.
1 and 11 are extended, and the rafter plates 11 of these triple heat collectors 4... collectively form a rectangular frame-shaped hanging plate. 12 is a heat insulating material inside the case 5.

The heat collector support frame 3 is a wooden vertical frame 1 with a rectangular cross section.
3, 13 and the horizontal frames 14, 14, and
It is formed into a rectangular frame whose outer dimensions are slightly smaller than the inner frame size of the rectangular frame-shaped hanging boards 11... of the continuous heat collectors 4..., and this support frame 3 is fixed on the roofing board 2 with nails, etc. Then, as shown in Figures 3, 4, and 5, the flashing boards 15 are attached from the top surface of the support frame 3 to the outer surface and spread 16 on the shedding board 2, and the upper end of each flashing board is screwed. 17... are fixed to the upper surface of the support frame 3, and each of the flashing plates 15... are connected watertightly by welding, folding, etc., and the vertical frame 1 of the support frame 3 is
3, 13, fix one side of the heat collector mounting material 18 made of angle material that spans the entire length of these frame materials to the upper surface of the horizontal frames 14, 14 using the screws 17... mentioned above, and fix the other sides. The support frame 3 is connected to the support frame 3 by elastic fin-shaped tight members 19 made of rubber or the like, which are hung on the outside of each of the frame members 13, 13, 14, 14 at a slight interval, and attached to the inner surface of the lower end of each mounting member 18. Mounting material 18
This creates a watertight seal between the two. In addition, a plurality of the heat collector mounting materials 18 may be fixed as short materials on each frame material of the support frame 3, and in that case, the tight materials 19 may be attached to each hanging plate 11. .

Among the above-mentioned flashing board materials 15..., the flashing board materials 15, 15 attached to the adjacent vertical frames 13, 13 of the adjacent support frames 3, 3 are made by bending a single board material almost into a channel shape as shown in the third figure. The extended portion 16' is formed into a downspout d extending in the direction of roof inclination.

The flashing plate material 15 is a metal plate such as an annealed aluminum alloy thin plate or a galvanized iron plate.

On the support frame 3 with mounting material 18 as described above,
The triple heat collector 4 is placed with its hanging plate 11 covered on the outside of the mounting material 18,
Each hanging plate 11 is fixed to a hanging portion of a mounting member 18 by a screw 20. The lower header pipe nozzle 7' and the upper header pipe nozzle 8' of the upper and lower adjacent heat collectors 4, 4 of the triple heat collectors 4 supported in this way are connected to the connecting pipe 2 on the outside of the heat collector.
1... are connected.

A water supply pipe 22 that supplies water to the triple heat collectors 4 and a hot water outlet pipe 23 that takes out hot water from the triple heat collectors.
For example, as shown in the second diagram, 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 pulled out from the base plate 2. It may be arranged to penetrate through and lead to the attic.

In addition, the upper surface of the space|interval between adjacent triple heat collectors 4... and 4... may be closed with a suitable cover.

Between the adjacent heat collectors 4 and 4 of the above triple heat collectors
In case S, tight material fitting grooves 25 are provided in the upper and bottom parts of the side walls of the opposing cases 5 and 5, respectively, as shown in figures 4 and 6, and these fitting grooves are filled with an elastic material such as rubber. A watertight tight material 26, 26 having a length that spans the entire length of the side wall is fitted and the above-mentioned space S is
At the same time as closing the upper and lower openings of the
The left and right openings of the same are filled with watertight tight materials 27, 27, and the hanging plates 1 of the adjacent heat collectors 4, 4 are
A watertight sealing material 28 such as caulking material is filled in the space between 1 and 11 continuously with the tight material 26.
When filling the sealing material 28, the adjacent hanging plates 1
The heat collector mounting material 18 closes the space between 1 and 11 from the back side and acts as a seal receiver.

Between the adjacent glass retainers 31, 31 of the adjacent heat collectors 4, 4, a rain retainer piece 32 extending from the upper glass retainer 31 in the roof inclination direction to the lower glass retainer 31 is extended. A tight material 33 made of an elastic material such as rubber attached to the tip of the piece 32 is pressed against the lower glass retainer 31, thereby promoting water-tight formation of S between the heat collectors 4, 4.

If the heat collector mounting material 18 is a short one that does not have the tight material 19, the short mounting material is placed in the position that closes the space between the adjacent hanging plates 11, 11 from the back side. Fix it as a seal holder like this.

When the short heat collector mounting material or other heat collector mounting material is used as the seal receiver between the adjacent hanging plates 11, 11, as shown in FIG. For example, a channel-shaped seal receiver 29 may be fixed to one back side by welding or the like so that the channel portion is located on the back side between the hanging plates.

In this case, depending on the case, the heat collector 4,
Between 4〓Tight material 26 of the upper opening in S,
It is also possible to omit the tight members 27, 27 and the flashing piece 32 for the left and right side openings.

In addition, at the shingle part of the roof (Fig. 3) and the eaves part (Fig. 4), the extended part 16 of the flashing board 15 is bent downward from the shingle end and the eaves, and the tip is secured with needles. It has been done. Also, the ridge part (Fig. 5)
In the above, the extended portion 16 of the flashing board material 15 is folded over the end of the ridge-suppressing member 30 covering the ridge in a water-backed state.

It goes without saying that the solar heat collector in the present invention is not limited to one configured to heat a liquid such as water as described above, but may also be appropriately configured to heat a gas such as air.

The roof mounting structure for solar collectors of this invention is an extremely simple structure in which multiple collectors with hanging plates are supported on a frame-shaped support frame fixed to the roof base material, yet it is possible to ensure sufficient watertightness and firmly support multiple collectors.Therefore, it can be easily implemented on newly built roofs as well as existing roofs, and can be easily installed on the roofs of ordinary houses.Furthermore, according to this proposal, the spaces between adjacent collectors of a multiple collector series can be kept watertight, thereby making it easy to support the multiple collectors on the support frame in a watertight state.
