Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mounting for a solar collector mounted on a roof.

Conventionally, solar heat collectors such as solar water heaters installed on a thatched roof have been installed on the thatched roof by a method as shown in FIG. That is, the solar heat collector 10 is placed directly on the roof 12, and the mounting part 1 is installed on the side of the solar heat collector 10.
4 and was directly attached to the roof with a wire 16.

However, when using such an installation method, there is a risk that the solar heat collector 10 may fall from the roof due to breakage of the wire 16 due to corrosion. In addition, roof tiles and slates were broken, and wires were cut due to strong winds, causing the solar heat collector 10 to fall. Moreover, the wire 16 that fixes the solar heat collector 10 and the water supply and water collection pipes 18 connected to the solar heat collector 10 are exposed, which is unfavorable in terms of appearance, and the use of solar heat collectors has become widespread. was delayed.

In order to prevent the above solar heat collector from falling, a pillar with plywood fixed to the lower end is attached to the roof, and a valley coil that matches the shape of the roofing material such as tiles is inserted into the pillar. The structure is disclosed (Japanese Patent Application Laid-Open No. 57-471
53). However, when using this method, the valley coils must be changed according to the shape of the tiles covering each roof.
Holes for passing the pillars drilled in the valley coils had to be drilled appropriately at the work site depending on the location, which made workability difficult.

The present invention has been made in order to eliminate the drawbacks of the prior art, and an object of the present invention is to provide a solar heat collector mounting fixture that allows a solar heat collector to be easily installed.

The present invention provides a metal tube with a fixing device for fixing the metal tube to a roof structure, a fixing device for identifying a solar heat collector, etc. on the metal tube, and a bendable metal tube between these fixing devices. The metal plate is fixed and the metal plate is deformed according to the shape of the roof tiles, etc. on which the solar heat collector will be installed, making it easy to install the solar heat collector. This is what I did.

1 and 2 are perspective views of an embodiment of the solar heat collector mounting device according to the present invention, and FIG. FIG. 4 is a sectional view showing a solar heat collector mounting fixture according to an embodiment of the present invention fixed to a roof; FIG. 4 shows a solar heat collector mounting fixture according to an embodiment of the present invention; It is a sectional view showing a state where it is installed on a roof.

In FIG. 2, the fitting 20 has a metal tube 22 made of a steel pipe or a stainless steel pipe inserted through a cover plate 24, and a heat collector fixture 2 is placed above the cover plate 24 of the metal tube 22.
6 is provided, and a roof fixture 28 is provided below the cover plate 24.
is provided. The cover plate 24 is made of a bendable rectangular or square metal plate made of lead or lead alloy, and preferably has a thickness of about 0.5 to 3 mm in consideration of bendability, weight, etc.

The contact portion 30 between the metal tube 22 and the cover plate 24 is fixed by welding or by Homoken adhesive, sealant, etc. to prevent rain leakage.

An example of the heat collector fixture 26 and the roof fixture 28 is shown in FIG. The heat collector fixture 26 in this embodiment has a pipe shape with a flange at the top, is fitted onto the metal tube 22, and is fixed to the metal tube 22 by welding or the like. Like the heat collector fixture 26, the roof fixture 28 has a pipe shape with a flange 32 formed at the top, is fixed to the metal pipe 22, and is fixed to the roof rafter 36 by a bolt 34. It is now possible to do so.

Attachment of such an attachment 20 to the roof is carried out as follows. A hole 38 is bored in the rafter 36, and this hole 38
Fix the roof fixture 28 to the roof fixture 28, insert the metal pipe 22 from above the rafter 36, and connect the flange 3 of the roof fixture 28
The lower surface of 2 is still in contact with the rafter 36. Thereafter, as shown in FIG. 3, the mounting bracket 38 is fixed to the rafter 36 using the port 34.

Next, as shown in FIG. 4, the cover plate 24 is bent to match the shape of the roofing material 40 such as tiles, and the lower side of the cover plate 24 along the slope of the roof is attached to one end of the roofing material 40. The lower end of another roofing material 40 is placed on the upper side of the cover plate 24. Thereafter, the mounting portion 14 of the solar heat collector 10 is placed on the heat collector fixture 26 and fixed with bolts or the like. Then, the upper part of the metal tube 22 is blind-covered.

By configuring the cover plate 24 using a relatively soft metal plate such as lead or lead alloy as described above, the shape of the roofing material 40 such as tile, slate, or shingle roofing material can be used at the site where the solar heat collector 10 is installed. It can be deformed into any shape according to the weather conditions, simplifying the installation work of the solar heat collector 10, and providing the same rain protection effect as the roofing material 40.

Moreover, since the cover plate 24 is a thin metal plate made of lead or lead alloy, it has a suitable weight and will not easily be turned over by wind or the like.

5 and 6 show other embodiments of the roof fixture. The roof fixture 28 in FIG.
It consists of a pipe 44 and a nut 46 that are fitted onto the metal tube 22 and fixed to the metal tube 22.

The pipe 44 has a 7/jet 32 formed at its upper end, and a fitting part 48 formed at its lower circumferential surface, and a nut 46 is screwed into this threaded part to connect the flange 9 part 32 and the nut. 46, it can be fixed to the rafters 36. The roof fixture 28 shown in FIG. 6 is a plate-like member fixed to the metal pipe 22. In this case, the method of fixing the fixture 20 to the roof is to bend the backing plate 24 upward as shown in FIG. 6, and then drive the nails 50 into the rafters 36 with a C/752, or attach them to the rafters with screws. I can do it. Moreover, when using this method, even in an existing house, several pieces of roofing material can be removed and the fixture 20 can be easily fixed to the rafters from above the roofing board.

FIGS. 7 to 9 are diagrams showing other embodiments of the heat collector fixture. The heat collector fixture 26 shown in FIG. 7 has a plate shape and is fixed to the metal tube 22. As shown in FIG.

The heat collector fixing device 26 shown in FIG. 8 consists of a pipe 54 with a threaded part on the outer peripheral surface, and circles &56 screwed into the threaded part of this pipe 54. The heat collector fixture 26 shown in the figure is a vibro 0 having a flank 58 on the upper part, and the vibro 0 is detachably attached to the metal tube 22.

Then, a bolt 64 is attached to the female threaded part 62 provided on the vibro 0.
screw together, and hold the bolt 64 to connect the pipe 60 to the metal pipe 22.
Fixed to.

Both of the heat collector fixing devices 26 shown in FIGS. 8 and 9 can adjust the fixing position of the solar heat collector 10 in the vertical direction of the metal tube 22. That is, the distance between the lower surface of the solar heat collector 10 and the roof can be freely selected. Moreover, the heat collector fixing device 26 shown in FIG. 9 can be made by drilling holes in the same roofing material as the roofing material 40, as shown in FIG. , and you won't notice the appearance.

FIG. 11 shows an inspection method when the position of the roof strength member such as the rafter 36 to which the fixture 20 is fixed does not match the mounting pitch of the heat collector. In this way, when the pitch between the roof strength members and the mounting pitch of the solar heat collector 10 do not match, fix the bridge bar 60 between the fixtures 20 and install the solar heat collector 10 on this bridge bar 60. Fix it. In addition, the code|symbol 66 shown in FIG. 11 is a field board.

In FIG. 12, a gold k device 22 with a mounting 20 is used as a relay pipe for supplying and collecting heat medium (water, oil, etc.) for the solar heat collector 10. By doing this, it is possible to eliminate the pipes that are conventionally installed on the roof, and the appearance and aesthetics of the roof are not impaired.

As explained above, according to the present invention, a solar heat collector can be easily installed on a roof.
