Description

[Detailed description of the invention] The present invention relates to a solar heat collection roof structure.

Conventionally, solar water heaters have been installed near the roof ridge, but because they are exposed to the outside, they look unsightly. On the other hand, in the conventional ridge structure, roof tiles are covered with waterproof roofing on the roofing board, and a cap board is placed on the ridge along the length of the roof board. It was fixed to the rafters with long nails that penetrated through the base plate, and the ridge cover covered the cap and was fixed with nails. As a result, there is almost no space inside the ridge wrapper, making it difficult to install a hot water tank in this area.Also, with this structure, strong winds can cause rainwater to seep into the caps and rot them, and during construction. There were disadvantages such as the need for skill due to the use of long nails.

The present invention eliminates the above-mentioned drawbacks and provides a roof structure in which a heat pipe for collecting solar heat is installed inside the tile and a hot water storage tank can be installed inside the ridge cover.

An embodiment of the present invention will be described below based on the drawings.

In the figure, the roof board 1 has a longitudinal cross-section with a valley-shaped notch 2a formed at the base of the upper surface of a pentagon, spanning both sides of the ridge, and is symmetrical with respect to the vertical plane on the center line of the ridge. A plurality of pieces of material 2 are placed at intervals in the direction of the ridge so that the top ridgeline is on the center line of the ridge and in a vertical plane. The girder 2 is attached to the roof board 1 by driving nails 8a diagonally downward from both sides of the ridge.
Fixed. The angle formed by the intersecting bottom surfaces of the valley-shaped notch 2a is set smaller than the apex angle formed by the left and right sheathing boards 1, 1 of the roof. both inclined shoulder surfaces 22 sandwiching the top ridgeline of the girder 2;
Upper frame members 3a, 3a each having a long rectangular cross section are provided on the upper frame members 22, and side frame members 3b, which are approximately the same shape as the upper frame member, are provided below the both sides 21, 21, respectively. 3b are attached continuously along the length direction of the ridge, and are fixed to the girder 2 with nails 8b and 8c. The upper frame material 3
A extends downward from the girder 2 on both sides of the ridge, and its outer end is flush with the outer end of the side frame member 3b.

Left and right roofings 4, 4 are continuously stretched from above the sheathing board 1, covering these shedding boards 1 and frame materials 3a, 3b, and both roofings are covered with girder materials 2.
Duplicated above. Then, a tile material 5 is placed on the roofing board 1 and close to the side frame material 3 via the roofing. The upper end of the tile material is fixed with nails 8d. Then, a ridge cover 6 made of a metal plate is attached to cover the upper part of the upper surface of the tile material 5 and the roofings 4, 4 that enclose the frame material 3. Since the ridge wrapping 6 covers the tile material 5, a downwardly bent contact piece 61 is formed at the lower end of the leg portion 6a along the slope of the tile material. Applicable piece 61
and the tile material 5 are made watertight by a caulking material 7. Then, the ridge wrapper 6 is attached with nails 8e from the outside of the side.
The material 2 inserted through the side frame material 3b by
Fixed.

As shown in the third figure, in the space of the frame 3 formed between the members 2 along the ridge length direction inside the ridge wrapper 6, there is a space on the ridge that is approximately the same width as the spar members 2 and is horizontal. A hot water storage tank 9 for a water heater having a bottom surface is installed. The outer surface of the hot water storage tank 9 is covered with a heat insulating material, and the hot water storage tank 9 is mounted on a frame 10 on the roofing boards 1 on both sides of the ridge. In addition, a heat pipe 32 embedded in the tile B is connected to the hot water tank 9 as described below, and a hot water pipe 12 and a water supply pipe 13 are connected to the roofing board 1, the roofing 4, or the ridge wrapping 6, respectively. connected through.

Next, tiles B with embedded heat pipes that absorb solar heat will be placed on the roof. FIG. 4 shows a state in which the rectangular flat tiles B are arranged in a staggered arrangement. The tile B is constructed as follows. The heat insulating main body 31 is made of a heat insulating material such as rock wool or asbestos cement, and has a rectangular flat plate shape that has the strength of a normal roof tile. A front positioning step 311 is provided on the lower surface of the front part of the main body to protrude downward along its front edge, and the step 311 is provided on the upper surface of the rear part of the main body along the rear edge.
A rear positioning step 312 is provided to protrude upward at the same height as 11. Further, on the upper surface of the rear step portion 312, there are a plurality of circular recesses 312a along the lateral direction of the tile from which the rear end of the heat pipe (described later) is exposed.
) are arranged at equal intervals.

A plurality of heat pipes 32 are embedded in the main body 31 in parallel with each other at regular intervals along the roof inclination direction. A portion of their outer circumferential surfaces are exposed along the surface of the main body 31. Moreover, these plurality of tiles are arranged at symmetrical positions with respect to the center line along the roof inclination direction of the tiles. The heating part of the heat pipe is on the lower side, the cooling part is on the upper side, and the tip of the heating part is bent toward the back side of the main body, and the tip protrudes downward from the back side behind the front step section 311. . Further, the tip of the heat pipe cooling portion is bent toward the front side of the main body 31, penetrates halfway into the rear step portion 312, and is exposed at the bottom of the recess 312a. Heat pipes are made of good thermal conductors such as copper, aluminum, and iron, and are highly corrosion resistant. Water, ammonia, etc. are used as a heat medium for the heat pipe.

On the upper side of the heat pipe, a heat receiving plate 33 is fixed to the main body 31 via an adhesive layer 34 between the heat pipe and the main body 31 in contact with the outer peripheral surface thereof. The heat receiving plate 33 is made of a material with excellent thermal conductivity and corrosion resistance, such as copper, aluminum, colored iron plate, or stainless steel. When two tiles like those described above are stacked one on top of the other, the connecting part between the cooling part and the heating part of the heat pipe 32 has a
A connecting agent 35 made of a heat-conducting adhesive mixed with easily meltable metal such as solder or metal powder is filled to ensure heat conduction.

According to the conventional method of roofing, as shown in Figure 4, the above-mentioned roof tiles are first laid out in a horizontal straight line, with a plurality of tiles placed side-by-side butt-to-bottom, and then the upper tiles are placed in a row with a width of 1/2 of the horizontal length. They are also placed horizontally in a straight line, shifted by . At this time, as shown in FIG. 5, the front and rear step parts 311 and 312 of the main bodies of the lower tile and the upper tile are engaged with each other to position them in the roof inclination direction, and the tip of the heat pipe heating section of the upper tile is positioned. It sinks into the recess 312a of the lower tile and comes into contact with the heat pipe cooling section of the lower tile. The cooling part of the top tile is connected to the roofing hole 4 through the heat pipe insulation material R.
a, it is connected to the hot water storage tank 9 through the notch 3b' of the frame.

Therefore, during the daytime when the water is exposed to solar heat, the hot water storage tank is at its lowest temperature, and then the roof tiles become hotter as you move down. Therefore, there will be a slight temperature difference between the heating section and the cooling section of the heat pipe in the lowermost tile. Therefore, the thermal liquid condensed at the lower end of the heat pipe due to the heat received in the lowest tile evaporates and rises, reaching the cooling section at the upper end, where it is transferred to the heating section of the heat pipe of the upper tile. give heat. Thereby, the vapor condenses into liquid and returns to the lower end due to gravity and the height difference caused by the roof slope. The above action is repeated again, and the heat from the lower tiles is transferred to the upper tiles. Thereafter, heat is sequentially transferred from the lower tile to the upper tile in the same manner, and finally the heat is transferred to the hot water tank 9.

Then, in the evening, when the sun's heat decreases and the tiles cool down to a temperature lower than that of the water in the hot water tank 9, the heat medium in the heat pipe 32 is in a liquid state and is pushed to the lower end by gravity and capillary action inside the heat pipe. The hot water remains stored, and the heat does not flow backwards from the hot water tank 9 to the tiles.

In place of the tile heat receiving plate 33, a heat receiving layer filled with a thermally conductive inorganic material may be used instead of the tile heat receiving plate 33.

FIG. 7 shows a second embodiment of the roof tile. In this example, the tile does not have front and rear stepped sections, and the cooling section of the heat pipe of the lower tile is bent upward and protrudes upward, heating the heating section of the upper tile via a heat conductive connecting agent. . In addition, in the third embodiment shown in FIG. 8, the heating part of the heat pipe of the upper layer tile is bent and protrudes downward, and the heat pipe is heated by the heat pipe cooling part of the lower layer tile provided below via a thermally conductive connecting agent. be done. Furthermore, in the fourth embodiment shown in FIG. 9, a stepped portion 313 is formed on the back surface of the upper layer tile on the upper side along the roof slope of the lower layer tile, and a heat pipe heating section bent and fitted in this step is connected with a good thermal conductor. It is heated by the cooling part of the lower layer heat pipe protruding from the rear end surface of the lower layer tile through the agent.

In the second and fourth embodiments of the tiles, a recess 312a to be filled with the thermally conductive connecting agent 35 is provided in the upper layer, and in the third example, the lower layer.

Further, FIG. 10 shows a fifth embodiment of the tile, and the tip of the heat pipe 32 is immersed into the tile without protruding from the outer surface of the tile, and at the connection part, heat is transferred into the connection hole 31a through the connection agent 35. A metal piece 36 is housed across the upper and lower tiles.

During construction, the nails 8a for nailing the girder 2 are driven approximately at right angles to the intersecting bottom surfaces of the valley-shaped notches 2a. Then, drive the nail until the head of the nail is buried in the wood 2. As a result, the shingled timbers 2 are firmly nailed to the roofing board 1, and the side frame members 3b are brought into close contact with the shingled timbers 2.

As described above, the present invention uses a special tile in which a heat pipe is built into the tile, and the hot water tank 9 is installed using the space inside the ridge cover, so these solar water heaters are not placed on the roof at all. No need to expose it.
It is sufficient to fix the stilts 2 to the roof board 1 using short nails 8a. Moreover, since the girder 2 and the frame members 3a and 3b are covered with the roofing 4, they are prevented from being corroded by the intrusion of rainwater. Furthermore, since the gap between the ridge wrapper 6 and the tile material 5 is made watertight by the caulking material 7, water intrusion is further blocked. Since the ridge wrapper 6 is integrally molded, it has a beautiful appearance, and is made even more beautiful by color printing.

In the above embodiment, two pieces of roofing 4 were used on the left and right sides, but one piece of roofing material 2 and one frame material 3a, 3b were used.
Of course, it may be covered with a single piece of roofing.

As described above, the present invention incorporates heat pipes into tiles and installs the hot water storage tank on the ridge, so these hot and cold water facilities are not exposed on the roof at all, and have a good appearance, and also have hot water. can be obtained efficiently,
It also had a great effect on energy conservation.

In addition, the ridge basically consists of multiple girders placed at intervals along the length of the ridge, an upper frame, and a side frame, and a hot water storage tank is installed in the space between these girders. be done. Therefore, a water storage tank that is completely watertight and has sufficient heat retention and strength can be prepared at a factory rather than at a construction site, and the hot water storage tank can be installed within a building in a short time. Moreover,
There is no risk of water leaking from the hot water tank. In addition, the strength of the ridge can be easily ensured, and the girders only need to be fixed to the roofing boards with short nails, and the girders and frame materials are wrapped in roofing to prevent corrosion due to rainwater infiltration. .
