This proposal further improves this structure and proposes a roof-mounting structure for a natural circulation solar heat collector that can be supported on the roof. The structure is designed to prevent damage to the roof panels due to the vibration and impact of the hot water storage tank during construction, or in the event of strong winds or earthquakes after construction, and to prevent accidents such as water leakage caused by this. be. The details of the present invention will be explained below with reference to the drawings.

In Figures 1 and 2, rafters 1 are supported parallel to the roof structure of the building, roof boards 2 are stretched over the rafters, and if necessary, waterproof paper is laid on top of them, and these rafters, roof boards, etc. A roof is constructed by covering a roof substratum 4 with roof plates 4, and in this roof surface, a roof surface that approximately corresponds to the installation base area of the heat collector part 5a of the natural circulation solar heat collection device 5 to be installed. A frame-shaped heat collector support frame 6 that rises appropriately from the roof plate surface is placed on the roof plate non-laying surface F, leaving the roof plate uncovered.
is fixed, and a heat collector section 5a to which a hot water storage tank section 5b is connected is supported on the support frame 6.

First, the heat collector part 5a of the heat collector 5 has the third and fourth parts.

The other hot water storage tank portion 5b has a hot water storage tank 34 installed inside a tank case 33 as shown in the second and fourth figures, and its support means are provided on the roof sloped upper portions of the left and right sides of the heat collector case 7. Vertical member 35,3
A hot water storage tank holding frame is formed by fixing one end of 5 and extending the other end upward, and fixing a cross member 43 between the extending ends of both vertical members 35, 35. In this structure, the tank case 33 is placed on the horizontal member 43 and fixed to the vertical members 35, 35 with bolts 36.

The hot water storage tank 34 connected and supported in this way is connected to the heat collector through circulation connection pipes 37 and 38 as shown in the fourth figure, and a water supply pipe connection nozzle 39 connected to the upper water supply port of the hot water storage tank 34; and hot water sampling pipe connection nozzles 40 and 41 connected to the lower and upper sampling ports of the tank 34, respectively, protrude outward from the sides of the tank case 33, and a drain nozzle connected to the lower base pipe 8 of the heat collector. 42 protrudes from the side surface of the heat collector case 7 to the outside.

Next, the heat collector support frame 6 is constructed by connecting four wooden frame members 20 with a rectangular cross section, and the outer dimensions of the frame are slightly smaller than the inner dimensions of the hanging plates 14 of the heat collector section. It is formed into a rectangular frame, and this support frame 6 is fixed on the roofing board 2 with nails, etc., and a rain flashing plate 21 is attached to each frame material 20 of this support frame from the top surface to the outer surface of each frame material. The upper ends of each flashing board are fixed to the upper surface of the frame material 20 with screws 22, and the side edges of adjacent flashing boards 21, 21 are watertightly joined. On the left and right frame members 20, 20 of the support frame 6 thus constructed, an inverted Ω-shaped heat collector receiving piece 23 is fixed at one end of the receiving piece at a position corresponding to the mounting piece 18 using the screw 22. It has been done. Among the above-mentioned flashing board materials 21..., the extended portions above the roof slope and on the left and right sides are stacked under the roof panels 4... as shown in the second and third figures, and the tips are bent into the water return 24, and the roof The downwardly extending part is the second
As shown in the figure, it is stacked on top of the roof board 4.

In this example, the roof board 2 is not provided on the inside of the support frame 6 and the attic is opened, but depending on the case, a roof board may be provided. The flashing plate material 21 is preferably a bendable material such as an annealed aluminum alloy thin plate, a metal thin plate such as a galvanized iron plate, or a synthetic resin sheet.

The heat collector part 5a with the hot water storage tank part 5b is mounted on the support frame 6 with the receiving piece 23 as described above, and the mounting piece 18 is attached with the hanging plates 14 hanging outside the support frame 6. ...Receiving piece 23...
When placed on top and fixed with bolts 25 and nuts 26, the hot water tank portion 5b is supported in a state appropriately spaced upward from the surface of the roof plate 4, as shown in the second figure.

The piping structure for water supply, hot water sampling, etc. is as follows. First, the water supply pipe connection nozzle 39 protrudes outside the tank case 33, and the hot water sampling pipe connection nozzles 40, 41.
Connecting pipes 44, 4 for piping made of flexible pipes
5 and 46, and if necessary, connecting pipes 47 are connected to the drain nozzle 42 by joints 48, respectively, and round piping holes 49 are opened in the left and right hanging plates 14, 14 at positions close to the respective nozzles. At the same time, U-shaped piping holes 50 cut from the upper end are opened at positions corresponding to the piping holes 49 of the left and right frame members 20, 20 of the support frame 6 and the flashing plates 21, 21, As shown in the third diagram, the piping holes 50 are opened above the pressure tangent line between the tight material 15 and the outer surface of the support frame 6, and the connecting pipes 4
4 to 47 pass through the piping holes 49..., 50... and are guided into the support frame 6 and the attic, and the water supply pipe 51, hot water sampling pipes 52, 53, and drain pipe 54 are arranged in the attic. are connected to each other by joints 55.

The actual connection work of the connecting pipes 44 to 47 is performed by, for example, connecting one end of each of the connecting pipes 44 to 47 to each pipe in the attic before supporting the heat collector section 5a on the support frame.
1 to 54, and let the other end look into the piping hole 50... from inside the support frame 6. Next, when placing the heat collector section 5a on the support frame 6, connect each connecting pipe 44 to 47. The other end is pulled out to the outside through the piping holes 49 of the hanging plate, and then connected to each nozzle 39-42. These operations can be easily performed because the connecting pipe is flexible.

The connecting pipes 44 to 47 are, for example, bellows-like flexible pipes, preferably those in which the peaks or valleys of the bellows are not continuous in a spiral shape. 5
Reference numeral 6 denotes a grommet for watertightly sealing the gap between the piping hole 49 of the hanging plate and the connecting pipe.

In this case, the connections between the water supply pipes, hot water sampling pipes, etc. in the attic and the water supply piping connections, hot water sampling piping connections, etc. in the hot water storage tank are not only through the flexible connecting pipes mentioned above, but also through the above-mentioned water supply, hot water sampling pipes, etc. This also includes a configuration in which the water is further drawn out from the attic through each piping hole and connected to the water supply, hot water sampling, etc. piping connections.

According to the roof mounting structure of the natural circulation solar heat collector of this invention, the hot water storage tank is held apart from the roof surface by the holding frame, so the hot water storage tank is protected from vibrations and shocks caused by strong winds, earthquakes, etc. There is no risk of damage to the roof panels or water leakage even if the hot water tank is exposed to water, and since it is not covered by rainwater flowing down the roof surface, the watertightness of the hot water tank can be ensured sufficiently. Furthermore, according to the present invention, since the heat collector section is supported by the support frame with its hanging plate covering the outside of the support frame, it also has the advantage of extremely good watertightness.
