This rafter 3 made of a metal profile, for example an aluminum alloy profile, is composed of a horizontal piece 5, a vertical piece 6 rising upward at the center thereof, and rising pieces 7, 7 rising upward on both sides of the horizontal piece 5. Side edges 7', 7' projecting outward are formed at the tops of the rising pieces 7, 7.

Further, an upper horizontal piece 4 is formed at the upper end of the vertical piece 6, and rainwater returns 4', 4' directed upward and inward are formed at both ends thereof.

In addition, drain grooves 8, 8 are formed between the upstanding pieces 7, 7 and the vertical piece 6, and are opened at the eave edge portions as drain ports, which will be described later.

On the other hand, on the lower surface of the surface plate 12, which consists of a heat absorbing plate 10 made of an aluminum plate or the like with a black heat absorbing surface 9 formed thereon, and a water pipe 11 made of a steel pipe or the like installed integrally in the longitudinal direction of the heat absorbing plate 10, a foamed synthetic resin is The heat insulating material 13 and the reinforcing plate 14 are stacked one after another to form a heat collecting plate main body 15 as a whole.

In this embodiment, the reinforcing board 14 also serves as a roofing board.

Further, plywood can be used for the reinforcing plate 14, and the edge of the surface plate 12 extends longer than the insulating material 13 and the reinforcing plate 14 and is bent downward to form a fold-down edge 16 for draining.
It is desirable to form a

The heat collecting plate main body 15 having the above structure is placed on the side edge 7' via an angle member 17 attached to the lower surface of the end to prevent falling off, and further via a spacing member 18 placed on the surface plate 12. A transparent plate 19 made of a glass plate or the like is mounted, and as a result, a space 20 is formed between the transparent plate 19 and the heat receiving plate main body 15.

In this example, the spacing member 18 is made of a backing that maintains watertightness between the surface plate 12 and the transparent plate 19.

Next, a two-character fixed angle 21 fixed to the lower side of the upper horizontal piece 4 of the rafter 3 is connected to the end edge 1 of the transparent plate 19 via a backing 22 formed below the fixed angle 21.
Hold 9'.

Each of the above-mentioned parts is constructed symmetrically on both sides of the rafter 3, and hooks are attached to both ends of the upper horizontal piece 4 so as to be finally attached to the upper horizontal piece 4 of the rafter 3. By pressing the lower surface of the protruding edge 25 of the cap cover 24 having the side protrusions 23 and 23 against the transparent plate 19 via the backing 25', the attachment of the heat collecting plate main body 15 and the transparent plate 19 is completed. do.

The above explanation has been made with respect to FIG. 2, which is a cross-sectional portion taken along line II-II in FIG. -III
This is shown in detail in FIG. 3, which shows a cross section along a line.

In this figure, the light-transmitting plate joining material 26 made of an aluminum profile or the like is connected to a horizontal member 27, a vertical member 28 planted in the center of the horizontal member 27, and a vertical member 28 extending from the upper end of the vertical member 28 to one side. The translucent joint material 26 is arranged so that the upper side member 29 is oriented downward with respect to the slope of the roof, and the upper side member 29 is formed in a cross-sectional shape with an extending upper side plate 29. It fits onto both ends of the side cross members 27 and supports the ends of the adjacent translucent plates 19 via the backing 30, and in this case, the lower translucent plate 19a with respect to the slope of the roof is attached to the backing 30. and the upper side member 29.

Note that a sealing material 3 is provided between the transparent plate 19 and the vertical member 28.
At the same time, on the upper side of the slope of the roof, the caulking material 32 is filled so that the upper surface of the transparent plate 19b on this side and the upper surface of the transparent plate joint material 26 are connected in a plane. Prevent dirt and dust from accumulating in the area.

A sealing material 31 and a backing 3 are placed on the lower side member 27.
A drainage channel 33 is formed between the light transmitting plate 19 and the light transmitting plate 19, and this drainage channel 33 is provided in a longitudinal manner to prevent rainwater or condensation water from entering from the edge of the transparent plate 19 for some reason. , and because it is inserted into the rafter 3 from the end of the light-transmitting plate joint material 26, the drainage channel 33 opens toward the drainage groove 8 of the rafter 3 at its end.

In this case, the folded down edge 16 prevents rainwater from entering the heat collecting plate main body 15.

Next, the fit of the eaves and ridge will be explained with reference to FIGS. 4 and 5.

First, at the eaves part shown in Fig. 4, the water pipe 11 shown in Fig. 2 is installed.
is connected to a lower header pipe 35 via a flexible jointed flat pipe 34, and the transparent plate 19 is provided up to near this part, and the area below it on the eaves side is a normal roof board 36.

The outer surface of the header pipe 35 connected to a water supply source (not shown) is surrounded by a heat insulating material 37.

The space 20 formed between the rafter 3 and the transparent plate 19 is the space 20 between the roof plate 36 and the rafter 3 in FIG.
0', and this space 20' communicates with the atmosphere at a drainage port 38 provided in the rafter 3 at the eaves,
Therefore, an air flow is formed within the spaces 20', 20, and the space 20 is also communicated with the atmosphere at the ridge portion shown in FIG.

That is, FIG. 5 shows a configuration in which the upper end of the water pipe 11 is connected to an upper header pipe 40 via a flexible spliced flat pipe 39, surrounded by a heat insulating material 41, and connected to a used end (not shown). The hot water in the upper header pipe 40 is sent out, and in this ridge part, a ridge ventilation unit 45 is attached on the ridgepole 42 via a ridge holder 43 and a cap 44, and a top plate part 46 and a side plate The roof ventilation unit 45 includes a section 47, an inner wall section 48, and a bottom wall section 49, each of which is made of a shaped material such as an aluminum alloy. 51. Bottom wall part 4
A drain port 52 is formed in 9, and these vent ports 50 and 5
1 ventilates the attic of the building, and at the same time, the space 20 is also communicated with the outside air.If the air is made to blow through from the eaves to the ridge in this way,
This eliminates air stagnation that would cause dew condensation due to condensation of moisture in the air on the inner surface of the transparent plate 19, and maximizes the heat collection effect of the surface plate 12 without reducing the transmittance of sunlight. can be done.

Note that the space 20 is provided at the eaves and ridge portions respectively.
Air is allowed to circulate only in the notch 54 provided in the partition wall 53 so as to block the air flow.

In the above configuration, the water pipe 1 is connected through the lower header pipe 35.
When water passes through 1, it passes through the transparent plate 19 and the surface plate 12
The water in the water pipe 11 is heated by the solar heat that heats the water pipe 11 and can be taken out as hot water, which is similar to known devices of this type. With a space 20 placed between the heat-receiving plate main body 15 having a heat insulating structure including the surface plate 12 and the transparent plate 19, it can be easily attached to the rafters 3 as a set, and can be attached to the roof of the building. Since there is no need for a double structure, the material cost is low, and work is easy because it can be handled as a set.Rafters 3 with drainage channels 8 can drain rainwater, making it easy to shut off rain. This has practical effects such as ease of use.
