Description

The present invention relates to a roof structure having a solar cell module, and more particularly to a roof structure in which a solar cell module is directly fixed to a base plate of a roof of a building.

The size of solar cell modules (hereinafter simply referred to as “modules”) constructed by fitting cell strings in which solar cells are connected in series into the outer frame is standardized by each manufacturer. Not.
Therefore, generally, for example, as shown in Japanese Patent Application Laid-Open No. 2012-117351 (Patent Document 1), a roof finishing material (tile) is rubbed and then a module fixing device so that remodeling is possible. The method of installing the module and fixing the module to the roof is adopted.

On the other hand, as disclosed in Japanese Patent Application Laid-Open No. 2000-336864 (Patent Document 2), a method of directly installing a module on a roof base plate is also known.

JP 2012-117351 A (Claims, FIG. 1) JP 2000-336864 A (Problems to be Solved by the Invention, FIG. 1)

Although the method described in Patent Document 1 in which a module fixing device is arranged on a rolled roof tile and the module is mounted on the fixed device has many advantages such as being able to be reformed, the size of the module itself is small. Since it differs from manufacturer to manufacturer, it is necessary to replace all the equipment except for the same manufacturer when renovating.
Furthermore, since the module fixing device is directly placed on the roof tile, an unexpected load may be applied to the roof tile or roof, so that there is a problem to be solved from the viewpoint of roof strength and maintenance.

  The method described in Patent Document 2 can mount the module directly on the base plate constituting the roof. Therefore, when laying the module in a large area, it is easy to construct and requires no special equipment, so it is economical. Yes, the size of the module itself varies from manufacturer to manufacturer.

  For this reason, when placing tiles or slate tiles on the entire roof surrounding the module, if the module size is given priority, the surrounding parts may contain small cuts depending on the location, resulting in loss and residual material. Therefore, there is an environmental problem such as waste of material and cost of processing of the generated scrap material, contrary to the part of utilizing natural energy.

  Furthermore, when using modules of the same size from the same manufacturer for renovation, there will be no particular problem, but if the size is different or if it is replaced with a module from another manufacturer, it will be laid on the roof. It is necessary to change all of the finished roofing materials (tiles).

  In particular, the stone-like thin plate-like slate roof tiles have different standards depending on the manufacturer as in the case of the module. Therefore, there is a problem that the amount of edge material generated varies depending on the slate roof tiles to be used.

In view of the present situation, the present invention is to fix the module directly to the field board, by setting the size of the module to an integer multiple of the working width of the slate roof tile to be used. It is an object of the present invention to provide a roof structure having a solar cell module in which a slate roof tile can be easily and easily laid, and generation of edge materials can be minimized.

In order to achieve the above object, the invention according to claim 1 of the present invention provides:
In the roof structure consisting of slate tiles and solar cell modules,
The slate roof tile works in a portion other than a portion overlapping with each other in the height direction, a portion other than a portion where a nail for fixing to the base plate is driven, and a portion defined by a length that is 1/2 of the length in the lateral direction. The width
The solar cell module has a depth that is an integral multiple of a longitudinal length of a working width of the slate roof tile, and a lateral width that is an integral multiple of a length that is ½ the lateral length. A roof structure having a solar cell module.

The invention according to claim 2 of the present invention is
In the roof structure having the solar cell module according to claim 1,
The field plate is
The entire surface is covered with waterproof paper.

The invention according to claim 3 of the present invention is
In the roof structure having the solar cell module according to claim 1,
The slate roof tile
The whole is plate-shaped, and its working width is about 182 mm in length and about 910 mm in width.

The invention according to claim 4 of the present invention is
In the roof structure having the solar cell module according to claim 1,
The field plate is
The entire surface of the solar cell module is covered with a waterproof sheet, and a carbon fiber plate having an area substantially the same as or larger than the bottom surface of the solar cell module is laid on the solar cell module. A step difference from the slate roof tile is eliminated.

  The roof structure having the solar cell module of the present invention has a portion other than a portion overlapping each other in the height direction (vertical direction) and a portion where a nail for fixing to the base plate is driven, and 1 / of the length in the lateral direction. A slate roof tile having a working width defined by a length of 2; a depth of the slate roof tile that is an integral multiple of the longitudinal length of the working width; and an integral multiple of the lateral length. Since it is composed of a solar cell module with a horizontal width, the generation of edge material that occurs on the slate tiles laid on the roof surface excluding the solar cell module is minimized, regardless of where the solar cell module is installed on the roof. Can be suppressed.

  In particular, in the present invention, the solar cell module is designed in conjunction with the working width of the slate roof tile to be used, so that the joint portion of the slate roof tile can be minimized and can be installed quickly and easily. It becomes possible.

Further, in the present invention, by interposing a carbon fiber plate having a required thickness between the solar cell module and the base plate, the step with the slate tile is eliminated as much as possible, and the unit is integrated with the roof surface. And a beautiful roof is constructed.
Furthermore, there is no need to lay slate tiles on the lower surface of the solar cell module, and there is no need for equipment to install the module, so it is possible to save waste of resources and greatly reduce the roof load. To demonstrate.

It is a schematic explanatory drawing which shows an example of the roof structure which has the solar cell module of this invention. It is a longitudinal cross-section of the principal part shown in FIG. It is a front perspective view which shows an example of the slate tile used for the roof structure which has the solar cell module of this invention, (A) shows a slate tile main body, (B) shows a starter. It is explanatory drawing which shows the construction method of the slate roof tile shown in FIG.

  Hereinafter, an example of the roof structure having the solar cell module of the present invention will be specifically described with reference to the accompanying drawings. However, the present invention is not limited only to the examples, and the scope does not change the gist thereof. Various changes can be made.

  Before describing an example of a roof structure having a solar cell module of the present invention, a slate roof tile 1 used in the present invention and a method of howling it will be described with reference to FIG.

As is apparent from FIG. 3A, the slate roof tile 1 is a rectangular flat plate as a whole, and has a thickness of about 5.0 mm, a width L of about 910 mm, and a depth H of about 410 mm. belongs to.
The slate roof tile 1 has a plurality of nail holes formed at a predetermined interval in order to fix the slate roof tile 1 to the base plate on the same line in the width direction at a portion having a height of about 230 mm from the lower edge. 2 is formed.

In addition, when the roof is spread with the slate tile 1, as shown in FIG. 3 (B), a rectangular shape having a thickness of about 5.0 mm × width of about 910 mm × depth of about 230 mm is provided. Slate roof tiles 4 called “starters” are used.
Since this slate roof tile 4 is also formed with a nail hole 2 for fixing to the base plate, a portion extending from the bottom of the nail hole 2 to the lower edge, in the embodiment, about 160 mm × 910 mm appears on the roof. Will be put out.

However, when slate tiles are laid on the roof, if they are laid in the height direction, that is, in the vertical direction, the lower part of the slate tile that is laid upward is overlapped with the upper part of the slate tile that is laid downward. To be beaten.
On the other hand, when rolling in the left-right direction, the side edges of the slate tile are in contact with each other. Are shifted by a length of 1/2 of the length and are staggered in the vertical direction.

  In such a slate tile 1, the height h from the lower part to the lower edge of the fixed portion 3 appears on the roof as a slate tile, but this region (width of about 910 mm × height of about 180 mm) When all the working widths are defined, when the size of the solar cell module is defined, the horizontal width of the solar cell module becomes very long, and the size of the general-purpose solar cell module cannot be obtained.

  Therefore, in the present invention, in order to make the size of the solar cell module versatile, the length of the region is ½ of the width, that is, the height direction of the slate roof tile. In this example, the working width is defined as a portion other than a portion overlapping each other and a portion other than a portion where a nail for fixing to the base plate is driven, and a portion defined by a length that is ½ of the length in the lateral direction.

That is, in the present invention, the “working width” refers to a case where, in the height direction, the lower edge portion of the slate roof tile arranged on the upper side is overlapped with the upper edge portion of the slate roof tile arranged on the lower side. The lower edge portion of the upper slate roof tile does not overlap, and in the lateral direction, it is defined as a region having a length half that length (approximately 455 mm in width × about 180 mm in height).
As a matter of course, the size of the slate roof tile varies depending on the manufacturer, but the definition of the working width is unchanged regardless of the slate roof tile of any manufacturer.

In general, when the slate roof tile 1 is laid on the roof R as shown in FIG. 1, the side edges of the slate roof tiles 1 are in contact with each other in the lateral direction. It is beaten toward the end side.
However, in the case where it is sown in the vertical direction, it is carried out with the lower edge of the upper slate roof tile 1 partially overlapping the upper part of the lower slate roof tile 1.

That is, when rolling up and down, as shown in FIG. 4A, the slate roof tiles 4, 4. The side edges of the slate roof tiles 4 are spread out in close contact with each other.
At that time, as a matter of course, each slate roof tile 4 is fixed to the base plate by a nail.
In this embodiment, the leftmost slate roof tile 4 having a width of about 455 mm is used.

  Next, as shown in FIG. 4 (B), the slate roof tiles 1, 1,... Are sequentially placed on the upper edge of the slate roof tile 4 while the lower edge of the reference slate roof tile 1 is overlapped. The left and right side edges are placed in close contact with each other.

Thus, when the first stage slate roof tiles are finished, as shown in FIG. 4C, the second stage slate roof tiles 1, 1,. While overlapping so as to be in contact with the upper edge of the width h, the left and right side edges are brought into close contact with each other in the direction from the other end to the other end, and the first slate roof tile 1 is staggered in the vertical direction. go.
Similarly, as shown in FIG. 4 (D), the slate roof tile 1 is sowed and the slate roof tiles 1, 1... Are similarly fired until the top of the roof R is reached.

In the solar cell module, a commercially available module has a depth of about 800 mm and a width of about 1,580 mm.
On the other hand, in the embodiment of the present invention, the size of the module 5 is set to 900 mm which is five times the depth 180 mm of the working width of the slate roof tile 1 to be used, and the horizontal width is 455 mm of the working width. Was set to 1,365 mm, which is three times as large as.

As shown in FIG. 2, after fixing the field board 7 which consists of a water-resistant plywood to the upper surface of the rafter 6 which comprises the roof R, the waterproof sheet 8 is stuck and fixed covering the surface of the field board 7 concerned.
Next, the height of the slate roof tiles 1, 1,..., Having the same size as that of the bottom surface of the module 5 and laid on the roof R at the part where the module 5 of the base plate 7 is to be attached. A carbon fiber plate 9 having substantially the same height is disposed, and the module 5 is fixed on the carbon fiber plate 9.

At that time, instead of the carbon fiber plate, a member obtained by processing a thin plate or a sheet metal can be used as a member for eliminating the step.
In the figure, reference numeral 10 denotes a makeup nose cover.

  After that, the slate tile 1 is laid along the depth and / or width of the module 5 fixed to the roof R. The depth of the module 5 is the depth of the working width of the slate tile 1, and the width is Since it is set to an integral multiple of 1/2 the length of the tile 1 in the lateral direction, it can be easily laid without causing any edge material to the slate roof tile 1 as much as possible.

  Further, since the carbon fiber plate 9 floats the module 5 from the surface of the base plate 7, by fixing the module 5 on the carbon fiber plate 9, a step with the slate roof tiles 1, 1,. , And can be more integrated with the roof surface to form a beautiful roof surface.

In this embodiment, the method of mounting the module 5 on the part where the roof R is desired to be installed and then laying the slate tiles 1, 1,. From the eaves side of the R, only the part where the module 5 is to be installed may be opened and laid sequentially, and then the module 5 may be fixed later to the part where the slate roof tile 1 is not laid.

The roof structure having the solar cell module according to the present invention can suppress the generation of edge material generated when slate tiles are laid as much as possible by providing a correlation between the module and the slate tiles that run on the roof. Therefore, the waste of resources is eliminated, and it can be widely used particularly in the construction industry of detached houses.
