Description

[Detailed Description of the Invention] This invention relates to a watertight structure of the upper and lower adjacent parts of the solar heat collectors that are vertically adjacent in the slope direction in a sloped roof in which a plurality of solar heat collectors are arranged.

The present applicant previously proposed a watertight structure for the upper and lower adjacent parts of adjacent heat collectors in this type of sloping roof, including a cover body that covers the upper and lower adjacent parts of the heat collectors, and a horizontal gutter part that protrudes from the main body. A horizontal cover consisting of is fixed to the lower heat collector in the inclined direction with screws, with its horizontal gutter part positioned between the upper and lower adjacent parts of the above heat collector, and the horizontal cover is connected to the upper heat collector in the inclined direction. We have proposed a watertight structure in which the rainwater that has entered between the heat collectors is received by the horizontal gutter, thereby effectively ensuring watertightness between the upper and lower adjacent parts of the heat collector.

This proposal further improves this, and fixes the horizontal cover to the upper heat collector in the inclined direction, making it possible to more fully ensure watertightness between the horizontal cover and the heat collector. The details of the proposal will be explained with reference to .

In Figures 1 and 2, a plurality of main buildings 1 supported on the sloping roof constituent surface of building F are mounted on rafters 2...
・ are fixed parallel to each other at regular intervals in a direction perpendicular to the main building, and on top of these rafters 2 are waterproof plates made of aluminum alloy plates, etc., with a length that spans almost the entire length of the slope of the roof. 3... and with the rectangular plate-shaped solar heat collector 4... placed above it, each adjacent waterproof plate 3, 3,... and Heat collector 4, 4,...
The left and right adjacent parts of each heat collector 4 are fixedly supported on the rafters 2, respectively, and the upper surfaces between the left and right adjacent parts and between the upper and lower adjacent parts of each heat collector 4 are fixedly supported. Vertical cover 5...
. . . and the horizontal cover 6 .

The watertight structure of the above-mentioned upper and lower adjacent parts is as follows.

First, the case 4' of the heat collector 4 is a flat box-shaped body with an opening on the top surface, and a flange 7 is protruded from the four circumferences of the opening edge on the top surface, and an inner flange 8 is protruded from a position slightly lower than the flange 7. Place the four circumferential parts of the transparent glass 9, and place the glass holding plate 10 on the four circumferential parts of the glass with a sealant interposed therebetween.
At the same time, the holding plate is fastened by screwing screws 11 to the flange 7, and the glass holding plate 10 has a hanging plate 12 extending further downward from its outer end at a right angle.

Reference numeral 13 designates a heat collecting plate disposed within the case 4' and having a flow path for heated fluid, and 14 designates a heat insulating material.

Such heat collectors 4 are fixedly supported on rafters 2 by screws 16 via brackets 15 as shown in the fourth figure, in a state where they are adjacent to each other with a small interval d above and below in the inclination direction. has been done.

As shown in the third figure, the horizontal cover 6 has an arm plate 18 protruding at right angles from the upper part of the lower surface of the flat horizontal cover body 17 in the inclined direction, and the lower end of the arm plate extends toward the upper part in the inclined direction in a U-shaped cross section. A channel-shaped horizontal gutter portion 19 is formed which is bent in a shape and opens upward, and a seat plate 20 further protrudes downward from the end of the horizontal gutter portion. protrudes at right angles, and the lower end of the arm plate is bent in a U-shape in cross section toward the lower part of the arm plate in the form of a channel-shaped horizontal gutter section 22 that opens upward. With the parts 19 and 22 positioned between the upper and lower adjacent parts of the heat collectors 4 and 4, insert the fixing screw 23 from the upper end of the cover body 17 to the upper and lower adjacent parts of the heat collector 4 in the upper direction in the inclined direction. It is screwed and fixed to the plate 10 and the flange 7, in which case the arm plate 18 is
In this example, the presser plate 10 in the upper heat collector 4 in the inclination direction is in contact with the hanging plate 12, and the side wall and seat plate 20 of the horizontal gutter part 19 are in contact with the lower surface in the inclination direction of the heat collector 4,
If necessary, the seat plate 20 may be fixed to the heat collector with screws 24.

The other horizontal gutter section 22 is located below the lower end of the hanging plate 12 of the glass holding plate 10, which is adjacent to the upper and lower parts of the heat collector 4 at the lower side in the inclination direction.

25 is a sealing material interposed between the cover main body 17 and the glass holding plate 10, and 26 is a caulking material for sealing between the upper end of the cover main body 17 and the glass 9 of the heat collector.

In this way, among the seal parts between the horizontal cover 6 and the heat collectors 4, 4, the seal part where rainwater flowing down the sloped roof is likely to enter is the seal part with the heat collector 4 located above the slope (sealing material 2).
5), but in this sealing part, the horizontal cover 6
Since the upper end is fixed to the heat collector 4 by the screw 23, the sealed state is maintained for a long period of time.

- If rainwater infiltrates from the seal part, the rainwater passes between the hanging plate 12 and the arm plate 18, flows down into the horizontal gutter part 19, is guided to the horizontal gutter part 19, and passes through an appropriate drainage structure. It is discharged to the outside.

Although there is no water leakage from the seal between the horizontal cover 6 and the lower heat collector 4 in the inclined direction, if rainwater intrudes, the hanging plate 12
It flows down into the horizontal gutter 22 and is discharged in the same manner as described above.

As an example, the rafter 2 supporting the heat collector is formed with a channel-shaped downpipe portion 28° 28 with an opening at the top on both left and right sides of the rafter main body 27 in the cross section as shown in the fourth figure. The open side end of the horizontal gutter section 19 is positioned above the horizontal gutter section 28 as shown in the fourth figure, and rainwater flowing through the horizontal gutter section 19 falls into the vertical gutter section 28 and is discharged downward through the vertical gutter section. It is like that.

The open side end of the horizontal gutter section 22 is similarly located on the vertical gutter section 28.

In FIG. 4, reference numeral 29 denotes a bracket protruding from the rafter 2 with screws, and the vertical cover 5 is fixed to the upper end of the bracket with bolts and nuts.

30. Reference numeral 30 denotes a pair of brackets fixed with bolts and nuts on the main building 1 with a fireproof board 31 in between, and the rafters 2 are fixed to these with bolts and nuts.

The waterproof board 3 has its left and right ends connected to the side walls 3 of the downpipe section 28.
2 is screwed to the upper end.

Another embodiment shown in FIG. 5 is an example in which the horizontal cover 6 is fixed by screwing fixing screws 23 from the arm plate 18 to the hanging plate 12.

According to the watertight structure between collectors of a roof with a solar heat collector of this invention, since the upper part of the horizontal cover in the slope direction is fixed to the collector in the upper part in the slope direction, rainwater can easily enter into the collector part in the upper part in the slope direction. The sealed state of the seal portion between the heat collector and the side cover can be maintained for a long period of time, thereby making it possible to maintain sufficient watertightness between the upper and lower adjacent parts of the heat collector.
