Description

[Detailed description of the invention] This invention integrates a heat absorption plate that utilizes solar thermal energy, a flow pipe, and a roof board, and simultaneously performs these functions to improve the temperature raising efficiency of water or hot water in the flow pipe. The present invention relates to a solar heat-utilizing roof plate that can be constructed simply and quickly and at low cost.

Recently, research and development on the use of solar thermal energy has been actively conducted as one of the energy saving measures.

Among these, many solar water heaters have been developed.

Most water heaters were installed on the roof or part of the wall of structures such as houses.

For this reason, the heat absorption area of the water heater is small, and the temperature raising efficiency, heat exchange rate, etc. are not necessarily good.

In addition, the water heater must be installed on the roof or wall after the roof or wall is thatched, which is extremely troublesome and may damage the roof or wall during installation, and this damage may cause rain leaks. There was a drawback.

Additionally, the attached water heater has the disadvantage that it is expensive in addition to the cost of the roof or walls.

Therefore, the present invention is a roof board in which chevron-shaped overlapping parts are formed on both sides of the main plate in the longitudinal direction, and a plurality of chevron-shaped parts are bulged out in the middle of the chevron-shaped overlapping parts of the main plate in parallel. A heat insulating material is filled between adjacent chevron parts, and the tops of the chevron parts filled with the heat insulating material are covered with heat absorbing plates and fixed to the chevron parts,
By forming one or more grooves on this heat absorption plate and fitting and fixing the flow pipes into these grooves, when a roof is constructed with this, a water heating system using solar heat can be constructed at the same time. The heating efficiency and heat exchange rate are also high, and since the roof, heat absorption plate, and water heating system using the distribution pipe are integrated, there is no damage to the roof, and construction and repair can be done easily and quickly, and at a lower cost. The above-mentioned drawbacks can be solved.

Its structure will be explained with reference to the drawings.

Reference numeral 1 denotes a long roof plate, which is made of weather-resistant metal and whose surface has been treated. On both sides of the main plate 2, substantially trapezoidal chevron-shaped overlapping portions 3.4 are formed.

The outer inclined part of this chevron-shaped overlapping part 4 is formed short, and is formed to be larger by the thickness of the chevron-shaped overlapping part 3 so that this chevron-shaped overlapping part 4 overlaps the chevron-shaped overlapping part 3 of the adjacent roof sheet 1. There is.

Reference numeral 5 denotes a substantially trapezoidal chevron-shaped portion, which overlaps the chevron-shaped overlapping portion 3 of the main plate 2.
．． A plurality of bulges (two ridges in FIGS. 1 to 5, three ridges in FIG. 6) are formed along the longitudinal direction in the middle of 4.

The size of the chevron portion 5 is approximately the same as the size of the chevron overlapping portion 3.4.

The roof board 1, which is integrally constituted by the main board 2, the overlapping part 3.4, and the part 5, is formed by bending a single strip using a large number of rolls.

6 is a heat insulating material such as glass wool or foamed synthetic resin;
It is filled on the main plate 2 between the adjacent chevron portions 5.5.

If the chevron portion 5 has two peaks (see Figs. 1 to 5),
Fill only between the gaps, but in the case of three peaks (see Figure 6),
Each of the spaces between the chevron portions 5.5 is filled.

Reference numeral 7 denotes a long heat-absorbing plate made of a metal with relatively good thermal conductivity such as copper, and has sloped edges bent downward from both sides of the flat part. In the middle, one or more grooves 8 into which the lower half of a flow pipe 9 to be described later is fitted are formed along the longitudinal direction.

The heat absorbing plate 7 is covered between the tops of adjacent chevron portions 5.5 filled with a heat insulating material 6, and both inclined edges of the heat absorbing plate 7 are fixed to the chevron portions 5 by spot welding or the like. .

At this time, the position of the groove 8 is configured such that it does not exist on the angular portion 5 but on the cross-sectional material 6, even if three or more angular portions 5 are provided.

Reference numeral 9 denotes a flow pipe made of metal or synthetic resin, which may be in the form of a circular tube (see Figures 1, 3, 4, 6, and 7), or in the form of a flat panel, with a In some cases, a large number of through holes are provided in the longitudinal direction (see Figs. 2, 5, and 8).

The flow pipe 9 is fitted and fixed in the groove 8 of the heat absorbing plate 7.

A surface plate 10 is made of transparent or translucent glass or synthetic resin, covers the upper surfaces of the flow pipe 9 and the heat absorption plate 7, and forms a sealed cavity with the heat absorption plate 7.

In the case of a flat surface plate (see FIG. 7), it is attached via a gasket or the like.

In the case of a flat mountain shape (see FIG. 8), the inclined edge thereof is fixed to the side portion of the mountain portion 5.5.

The surface plate 10 may not be provided (see Figs. 1 to 5).
(see figure).

11 is a structural member such as a main building of the structure, and 12 is a roof bracket.

Next, the effects will be explained.

First, the flow pipe 9 and the roof plate 1 with the heat absorption plate 7 are attached to the structural material 11.
Then, the chevron-shaped overlapping portion 4 of the adjacent roof sheet 1 is overlapped with the chevron-shaped overlapping portion 3 of this roof sheet 1 from above and fixed with bolts or the like. , this process is repeated one after another to form the roof.

Then, the lower ends and upper ends of the large number of flow pipes 9.9 are connected to each other by a lower connecting pipe and an upper connecting pipe (not shown) to complete the construction of the hot water system.

In this way, in the present invention, the roof plate 1 has the chevron-shaped overlapping portions 3.4 formed on both sides of the main plate 2, and the heat absorption plate 7 and the flow pipe 9 are provided on the main plate 2, thereby improving the structure. It is placed on the structural material 11 of the object, and the adjacent roof board 1.
When the opposing chevron-shaped overlapping parts 3.4 of 1 are sequentially polymerized and fixed,
Installation of the heat collection section or heat exchange section that utilizes solar thermal energy can be completed at the same time as the roofing, allowing for simple and quick construction.

Furthermore, the heat absorption plate 7 and the flow pipe 9 as the heat collecting part are
It exists between the chevron parts 5.5 on the inner side of the chevron overlap parts 3.4, and when roofing is done, the heat collecting part does not interfere with the roofing, and can be roofed in the same way as ordinary roofing sheets. It is possible.

Further, in the present invention, a plurality of chevron portions 5 are provided in the middle of the main plate 2.
is formed into a bulge, a heat insulating material 6 is filled between the adjacent chevron portions 5.5, and a heat absorbing plate 7 is provided so as to cover between the tops of the chevron portions 5.5 filled with the heat insulating material 6. One or more grooves 8 are formed in this heat absorbing plate 7, and a flow pipe 9 is fitted and fixed in this groove 8, so that the flow pipe 9, which contains water or hot water, is exposed to the radiant heat of sunlight. However, the heat generated by the heat absorption plate 7 is conducted to the flow pipe 9 through the groove 8, and the temperature raising efficiency or heat exchange rate of water or hot water by solar thermal energy can be extremely improved. ,
The presence of the heat insulating material 6 on the lower surface of the heat absorbing plate 7 can prevent the hot water in the flow pipe 9 from radiating heat downward.

In addition, since the roof plate 1 and the heat collecting part are integrated in advance at the factory, there is no need to attach them to the roof or wall separately as in the past, and the roof etc. will not be damaged at that time. The cause can be prevented, the construction can be done more quickly than the conventional method, and the heat collecting part can be installed using the structure of the roof board 1 without using any special parts. It is economical and can be provided at low cost.

Furthermore, since each roof plate 1 is provided with a heat collecting section, it is possible to heat a large amount of water.

Moreover, when the roof plate body of the present invention is installed, the appearance is almost the same as a conventionally known roof, and an extremely neat and elegant roof with a built-in water heating device can be obtained.

In addition, a heat insulating material 6, a heat absorption plate 7, a flow pipe 9, that is, a heat collecting section is built in the middle of the main plate 2, and the other parts are a flat main plate 2.
Since the heat absorbing plate 7 and the flow pipe 9 may accumulate dust and deteriorate heat absorption, or if they are damaged, the heat collecting part may be damaged. It can be easily cleaned or repaired by riding on the main plates 2 on both sides, and the heat collecting part will not be damaged, and the heat collecting part is not related to the chevron-shaped overlapping parts 3.4 on the left and right sides of the roof board 1. Since it is provided in a portion, even if a heat collecting portion is provided, there is an effect that no cause of rain leakage occurs due to this.

Note that if the flow pipe 9 and the heat absorption plate 7 are configured to be covered with the surface plate 10 with a certain gap, the flow pipe 9 and the heat absorption plate 7
An air layer is formed that is isolated from the outside air, and this air layer acts as a heat insulating layer to prevent heat radiation from the hot water, and when the temperature of the air layer increases (approximately 130 degrees Celsius), the water or hot water inside the flow pipe 9 It is possible to raise the temperature further.
