Description

[Detailed description of the invention] The present invention relates to a structure for mounting a solar heat collector on a roof surface, which is suitable for so-called roof integrated type, in which the heat collector also serves as a part of the roof board and is fixed to the roof base material. .

It has been conventional practice to install solar heat collectors on the south roofs of houses for the purpose of hot water supply and heating/cooling, and various mounting structures have been proposed for roof-integrated heat collectors. However, not only do they require complex structures to maintain watertightness, but they also do not have sufficient mounting strength, making them unsuitable for installation on roofs, especially on the roofs of ordinary houses. However, there were still problems with installing it on an existing roof.

The present invention has an extremely simple structure for installation on the roof, can be installed on a strong roof by simply installing appropriate members on the roof side, and has excellent watertightness. The purpose is to provide a mounting structure for a solar heat collector.

The present invention will be described in detail below with reference to the drawings.
In the figure, a roof base material is formed by laying waterproof paper or the like on a roof board or roof board 1 of a building. A solar heat collector is installed on the roof base material as shown below, but other parts are covered with roofing materials such as slate, metal plates, tiles, etc. (not shown) to form the roof.

In the above-mentioned roof base material surface, a solar heat collector support frame 3 is installed, which rises upward as appropriate, on the non-roofing surface that corresponds approximately to the installation base area of the solar heat collector 2 to be installed. The heat collector support frame 3 is constructed by laying wooden flat timbers 4 or two metal shapes equivalent to wooden flat timbers on the left and right sides of at least one heat collector on the shedding board 1. Through it, it is fixed in a hanging position (not shown). Further, rectangular members 4 are laid in the same manner at right angles to the upper and lower ends of the two rectangular members 4 in the slope direction to form a rectangular frame-shaped heat collector support frame 3.

Rain restraint construction is performed on the square frame-shaped heat collector support frame 3. The flashing board material 5 is made of a thin plate such as a colored steel plate or an aluminum plate, and is attached to the outer surface from the top surface of each rectangular board 4, stretched to an appropriate length 6 on waterproof paper, and the upper end of each flashing board material 5 is nailed. , are fixed to the rectangular member 4 with screws 7, etc., and the butt corners of the rectangular member 4 are joined to each other in a watertight manner using means such as welding or folding. Further, the upper end of the flashing plate material 5 is bent upward to form a water return 8.

The solar heat collector 2 shown as a heat collector that heats liquid such as water is constructed by opening the flat upper surface of a flat box-shaped case 9 and fitting a light-transmitting plate 10 such as glass into the case 9. A lower base pipe 11 for water supply and an upper base pipe 12 for taking out hot water are arranged, and a heat collecting plate 14 having a large number of channels 13 through which hot water flows is connected between the two base pipes. Reference numeral 15 denotes a heat insulating material in the case 9 that surrounds the sides and bottom of the combination of the base tubes 11 and 12 and the heat collecting plate 14, and is made of glass wool or the like.

At the bottom of the heat collector case 9, a rectangular frame-shaped hanging plate 16 is vertically installed along the four peripheral walls of the case. The hanging plate 16 has an outer wall portion 17 and a rising portion 18 to be placed on the upper surface of the support frame 3, and is formed into a key-shaped cross section. As shown in the figure, a C-shaped channel 19 is formed on the inner lower edge of the outer wall portion 17 of the hanging plate 16, and a tight material 20 made of an elastic material such as rubber or plastic and having a tongue-shaped cross section is attached to the channel 19 in the form of a cantilever. Installing. The outer wall portion 17 of the hanging plate 16 is formed into a square frame shape that is larger than the heat collector support frame 3 described above, and when the hanging plate 16 is placed on the support frame 3, it covers the outer surface of the support frame 3. The gap W between the flashing board material 5 and the outer wall portion 17 of the hanging board 16 is approximately 15 mm. In such a gap W, the tip of the tight member 20 elastically contacts the flashing plate 5 to close the gap W in a watertight manner. The tight material 20 is provided inside the four circumferences of the outer wall portion 17 of the hanging board, and a notch (not shown) is provided in the lower portion in the direction of the roof slope to drain water.

The reason why the heat collector case 9 and the hanging plate 16 are formed separately in the present invention is to facilitate the installation of the horizontal gutter 21 when a plurality of heat collectors are connected in the slope direction, and to make it easier to install the horizontal gutter 21 if necessary. This is because hanging plates of a different design can be replaced and installed. Therefore, in some cases, the case 9 and the hanging plate 16 can be integrated to simplify the work.

Prior to installing the heat collector 2, the heat collector mounting bracket 22 is attached to the rectangular member 4 in the longitudinal direction of the heat collector support frame 3 fixed on the roof base material. The mounting bracket 22
is a short-side member with a square cross-section, and normally four mounting fittings 22 are used for one heat collector 2. Mounting bracket 2
2 is attached to the rectangular material 4 covered with the flashing board material 5 using screws or the like. Next, angle plates 23 corresponding to the above-mentioned mounting brackets 22 are caulked in advance to the assembly of the heat collector 2 and the hanging plate 16 on which the tight material 20 is attached, and the angle plates 23 are attached to the rising part 18 of the hanging plate 16.
is fitted on the outside of the heat collector support frame 3 so that the lower end of the rectangular member 4 comes into contact with the upper surface of the rectangular member 4, and the angle plate 23 and the mounting bracket 22 are fastened with bolts or the like. Note that the portions of the hanging plate 16 and the like that overlap with the mounting fittings 22 are cut out in advance.

When using the heat collector mounting structure of the present invention, rain that falls on the roofing material flows down the roof surface along the outside of the square frame-shaped support frame 3 that stands above the roofing material surface. There is no flow into the inside of 3. In addition, even if rainwater rises up the side surface of the support frame 3 due to surface tension, it is prevented by the tight material 20.
Even if a small amount of rainwater passes through the part 0, water intrusion into the support frame 3 is completely prevented by the rising part 18 of the hanging plate 16 and the water return 8 at the upper end of the flashing plate 5.

As described above, the present invention is configured as described above, and the square frame-shaped heat collector support frame is formed smaller than the square frame of the hanging plate hanging from the four circumferences of the heat collector to support the heat collector. When fixed to the frame, the tip of the elastic support beam-like tight material attached to the hanging plate is in close contact with the outer periphery of the support frame, which has the effect of maintaining sufficient watertightness with an extremely simple structure. .
