Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a structure in which a solar heat collector that absorbs solar heat rays using water, air, etc. as a heat medium is installed on a sloped roof surface and also serves as a roofing material.

This type of structure, which has been used in the past, uses mounting brackets to fix heat collectors formed in a roughly rectangular box shape on the roof, and covers the gaps between each heat collector with a cover material. Consists of roofing material.

In the system shown in FIGS. 5 and 6, a vertical cover material 2' and a horizontal cover material 3' are disposed in a cross pattern above the gap between adjacent heat collectors 1' and 1', and each cover The gaps between the upper edge surfaces of the heat collectors 1' and 1' are closed with gaskets 4' interposed between the horizontal cover members 3' and the notches of the vertical cover members 2'. penetrates through. The above-mentioned cover materials 2' and 3' are connected to the heat collector 1',
1', screw receivers 5', 6' are hooked to the holes drilled in the end face of the heat collector facing the gap, and the cover members 2', 2' are fixed via the screws 7', 8'. 3' and screw receivers 5' and 6', respectively.

The above system has a simple structure, but since it uses only the cover material and gasket to protect against rain, water leakage will occur if the gasket cracks due to deterioration or the like.

An improvement on the above method is the system shown in FIGS. 7 and 8. This method uses a cover material and a gutter to catch water leakage, and vertical gutter 9' and horizontal gutter 10' are placed below the heat collector in the gap between heat collectors 1' and 1'. The screw groove member 1 fixed to both gutters 9' and 10'
1', 12' are connected to the respective cover members 2', 3' via screws 13'. At this time, as shown in FIG. 8, a portion of each of the vertical cover material 2' and the vertical gutter 9' is cut out to allow the horizontal cover material 3' and the horizontal gutter 10' to pass through.

This method provides complete rain protection compared to the methods shown in Figures 5 and 6, but requires both a cover material and a gutter, and also requires a gap between the heat collector and the roof underlayment. Since both gutters 9' and 10' are provided between them,
The drawback is that it not only takes time and effort to construct, but also increases material costs.

The present invention has been made in view of the above, and includes a drain section formed integrally with the main body of the heat collector at the upper part of the four circumferences of the heat collector, and a drain section located below the drain section and in the middle of the gap between the heat collectors. To provide a roof rain protection structure consisting of an economical and complete heat collector by arranging vertical gutters and horizontal gutters.

The present invention will be explained below with reference to Examples.

Figure 1 shows heat collectors 1, 1,...
..., each heat collector 1 is in the vertical direction (direction along the roof slope) and horizontal direction (direction parallel to the ridge direction)
They are placed with a gap between them. The left side of the figure shows a state in which the cuts of the horizontal gutter match the gaps in the vertical direction, which will be described later, and the right side shows a state in which the horizontal gutter intersects with the gaps in the vertical direction.

Figure 2 is a cross-sectional view along the slope of the roof showing the gap between the heat collectors 1 and 1 arranged along the slope of the roof, and shows the top of the rafters 2 or roofing boards 3 that form the base of the roof. A heat collector 1 is fixed with a mounting bracket 5 through a waterproof paper 4. Adjacent heat collector 1,
1, a conduit 6 for flowing a medium is connected to a connecting pipe 7.
A grommet 8 is provided on the end face of the heat collector body 9 to guide the conduit 6.

The heat collector 1 used in the present invention is of a known type that uses water or air as a medium, and has a glass plate 10 placed on its upper surface to transmit solar heat rays. In order to attach this glass plate 10 to the heat collector 1,
At the top of the four peripheries are screw receivers 9A on the top of the heat collector body 9.
A glass plate holder 11 fixed with screws is provided (FIG. 2 shows the glass plate holder 11 in the horizontal direction). The edge portion of the glass plate holder 11 that is separated from the glass plate 10 is bent downward to form a draining portion 11A. A similar drain section 9B is also formed integrally with the heat collector body directly below the drain section 11A. Note that 12A and 12B are upper and lower gaskets that hold the glass plate 10 in a sealed manner.

A horizontal gutter 13, which also serves as a cover to close the gap, is disposed between the heat collectors 1, which are vertically adjacent to each other along the slope of the roof. The upper surface of the horizontal gutter 13 is almost on the same plane as the glass plate holder 11, and the upper and lower end surfaces of the heat collector along the slope and the drain section 11 are located on the same plane.
A, 11A is provided with a slight gap, and at the bottom there is a horizontal gutter part 1 bent in a U-shape with an upward opening.
4 and 14 are formed. The above-mentioned horizontal gutter 13 is connected to the heat collector bodies 9, 9 using L-shaped cross-section receiving metal fittings 15, 15.
It is convenient to attach it to the opposite end faces of the

FIG. 3 is a sectional view taken along the - line in FIG. 1, and a vertical gutter 16 having a U-shaped cross section and opening upward is attached to one end surface of the heat collector body 9. This vertical gutter 1
6 is housed within the thickness of the heat collector 1 rather than under the heat collector, unlike the conventional system. The glass plate presser 11 and the heat collector body 9 in the vertical direction are each provided with a water drain section 1.
1A, 11A and drainage parts 9B, 9B (these drainage parts 9B, 9B are formed integrally with the heat collector body), and a small gap is provided between each drainage part. In FIG. 3, the horizontal gutter section 14 is partially cut out at a location 17 to allow the horizontal gutter section 14 and the vertical gutter 16 to communicate with each other.

Watertight materials 18 and 19 made of an elastic material such as rubber are fitted between the thus formed draining portion 11A and the horizontal gutter 13 in FIG. 2 and between the draining portions 11A and 11A in FIG. 3, respectively, to complete the assembly. Incidentally, if a part of the screw receiver 9A shown in FIGS. 2 and 3 is cut out at the lowest position when the heat collector is installed, rainwater that has entered through the gasket 12A can be easily drained onto the side gutter, which is convenient for drainage. Incidentally, instead of the watertight material described above, a sealing material made of an amorphous sealing material may be used as the watertight material.

FIG. 4 shows a case where the horizontal gutter 13 is discontinuous above the vertical gutter 16. In this case, horizontal gutter 1
Since there is a gap between 3 and 13, the notch 17 is unnecessary.

As explained in the conventional example, the watertight materials 18 and 19 constructed on site are not completely watertight against rainwater because of deterioration due to aging, water leakage due to capillary action, water leakage due to wind pressure, etc. Therefore, if there is a leak in the watertight material, the rainwater enters the horizontal gutter section 14, then flows through the vertical gutter 16 that slopes along the roof surface and is discharged to the outside. Therefore, water leakage will not enter the indoor side. Furthermore, when the draining section 9B is formed, it is also possible to omit the draining section 11A.

Since the present invention is constructed as described above, even if there is water leakage in the watertight part, it can be drained outside through the drainage part and the gutter, so if the roof is formed with a heat collector, the water leakage can be carried indoors. There is no need to consider the watertightness of the area around the drain because the water drain is formed integrally with the heat collector body. Furthermore, since it is not necessary to use both the cover material and the gutter together, and the gutter is not disposed between the heat collector and the roof base material, it has the advantage of easy construction and low material costs.
