Description

[Detailed Description of the Invention] This invention relates to a roof-mounting structure for a so-called roof-integrated solar heat collector, in which the solar heat collector also serves as a part of the roof plate and is attached to the roof surface.

The inventor first proposed a solar heat collector by fixing a frame-shaped heat collector support frame that rises appropriately above the roof surface on the roof base, and placing a ready-made heat collector on the support frame. We proposed a roof-mounting structure.

This proposal further improves this by lowering the protruding height of the heat collector from the roof surface and making it possible to install the pipes connected to the heat collector within the heat collector support frame without exposing them to the outside. It is configured so that it can
The details of the present invention will be explained below with reference to the drawings showing the mounting structure of the dual heat collectors.

In Figures 1, 2, and 3, rafters 1 are supported parallel to the roof structure of the building, and roofing boards 2 are placed on the rafters.
, furthermore, stretch waterproof paper 3 on top of each,
These rafters, roofing boards, and waterproof paper constitute a roof base, and a rectangular frame-shaped heat collector support frame 5 rising from the roof board surface at an appropriate height is fixed to this roof base, and is adjacent to the support frame on the left and right. Two heat collectors 6, 6' connected together are supported, and the roof subsurface around the support frame 5 is covered with slate, metal plate, or other roofing board 4 to form a roof. be.

First, in this example, the solar heat collectors 6, 6' are of a type that heats liquid such as water, and their structure is that of a flat box-shaped case 7 as shown in FIGS. A transparent glass 8 is fitted on the upper surface of the flat opening, and a lower base pipe 9 for water supply and an upper base pipe 10 for hot water extraction are installed inside the case 7, and a heat collecting plate 11 having multiple channels 12 between the two base pipes. Mounting flanges 17 are integrally protruded perpendicularly to the outer surface of the case 7 at intermediate portions (slightly upward in this example) of the outer surface of the case 7. In one of the heat collectors 6, 6', the nozzle 13 is inserted through the side surface of the case 7 from the right end of the lower base pipe 9, as shown in the fourth figure.
Similarly, nozzles 14, 14 are protruded to the outside from the left and right ends of the lower base pipe 9, respectively, and nozzles 13', 14 are similarly protruded from the left and right ends of the lower base pipe 9 in the other heat collector 6'.
3' and a nozzle 14' are similarly protruded from the left end of the upper base pipe 10, and the nozzles 13, 13' and 14, 14' are arranged so that the heat collectors 6, 6' are adjacent to each other on the left and right sides. Connecting pipe 15,1
6, respectively, to form a two-unit configuration. 18 is a heat insulating material inside the heat collector.

Next, in this example, the heat collector support frame 5 has a vertical dimension inside the frame (a dimension of the top and bottom of the roof slope) that is slightly larger than the vertical dimension of the heat collector 6 or 6', and The dimensions are appropriately larger than the left and right dimensions of the dual heat collectors 6, 6', and the frame material of this support frame is made of aluminum alloy extrusion, other metal plates, or synthetic resin, and its cross-sectional shape is are the second and third

1... Seal material 24 such as caulking agent between the top surface
is filled and sealed watertight.

The lower bodies of the dual heat collectors 6, 6' (the portions below the mounting flanges 17) are inserted into the support frame 5 from above, and the upper and lower sides of each heat collector are bent. Mounting flanges 17, 17 are placed on upper and lower support flanges 22, 22 of the support frame 5, and the heat collector 6,
6', and at that time, a piping space S is provided between the left and right outer surfaces of the dual heat collectors 6, 6' and the left and right inner surfaces of the support frame 5, and in this state, the flanges 17, 17 are , 22, 22 are fixed with screws 25...

A water supply pipe 30 and a hot water outlet pipe 31 are connected to the lower base pipe nozzle 13' of the heat collector 6' and the upper base pipe nozzle 14 of the heat collector 6 in spaces S and S in the support frame 5, respectively. , these tubes 30,3
1 is led to the attic from a convenient position within the space S, S through the roof board 2, and is extended to a predetermined position.

A cover 26 is placed on the open upper surface of the space S, and the four sides of the cover are placed on the left and right mounting flanges 17 of the heat collector and the left and right and top and bottom support flanges 22 of the support frame 5, respectively. screw 27
Fixed by... A cover 28 is placed on the open upper surface between the heat collectors 6, 6', and the four sides of the cover are attached to the mounting flanges 17, 17 on the left and right sides of the heat collectors and the support flanges on the top and bottom sides of the support frame 5. 22, 22, and are fixed thereon by screws 29, respectively. Note that the mounting flange 17, the support flange 22, and the cover 26, and the support flange 22 and the cover 26 are watertightly sealed by appropriate means such as sandwiching waterproof packing.

The sealing between the roof plate and the outer seat plate with the sealing material is performed by supporting frames 5a of the roof plates 4a, as shown in FIG.
Bring the end of the support frame closer to the support frame upright part 19a, and then move the roof board 4a...the end, the outer seat board 21a, and the upright part 1.
Alternatively, a groove 30a may be formed between the grooves 9a, and the sealing material 24a may be filled in the groove.

In another embodiment shown in FIG. 6, the frame body of the heat collector support frame 5b is provided with an outer seat plate 21b at the lower end of the upright portion 19b and a support flange 22b at the upper end, and the inner seat plate is removed. As shown in the figure, the outer seat plate 21b
are fixed to the roof board 2b with screws 23b..., and the roof board 4b... is fixed on the outer seat board 21b with the screws 23b.

A composite outer seat plate 33c is formed by spreading 32c on a waterproof paper 3c from above, and the upper end is fixed to the support flange part 22c using screws 27c. Of the formed composite outer seat plates 33c..., on both left and right sides and on the upper side of the roof slope, the roof plate 4c is placed on the flashing plate extended portion 32c... as shown in FIG. 7.
At the same time, the tip of the spread part is bent into an upward water return 34c, and in the composite outer seat plate 33c on the lower side of the roof slope, the flashing board material spread part 32c is bent as shown in Figure 7a. A roof plate is placed underneath, and the tip of the extension part is bent into a downward water return 35c, and the other structures are substantially the same as those in FIGS. 1, 2, and 3.

Of course, the solar heat collector of the present invention can also be of a type that heats gas such as air.

According to the solar heat collector mounting structure on the roof of this invention, since the heat collector is supported in a recessed state within the support frame, the protrusion height from the roof surface is reduced and the appearance can be improved. In addition, a space for piping can be formed between the support frame and the outer surface of the heat collector, and piping can be installed within the space, which further contributes to improving the appearance.
