Description

  The present invention relates to a solar cell module provided with a flange for flowing rainwater, and also relates to a roof structure formed by laying such a solar cell module. Furthermore, this invention relates to the eaves extension member for solar cell modules used attaching to the solar cell module provided with the eaves part for flowing rain water.

  In recent years, there has been a photovoltaic power generation system in which a solar cell module is installed on a roof such as a roof of a general house or a roof of a building, and the power used in the building is covered by solar power generation and surplus power is sold to an electric power company. It has become widespread.

  A solar cell module employed in this type of solar power generation system is generally formed by mounting a solar cell panel provided with a photoelectric conversion element on a metal frame. Here, some metal frames constituting a part of the solar cell module have a flange portion for flowing rainwater at a position adjacent to a main body portion on which the solar cell panel is mounted.

For example, in Patent Document 1, a solar cell arrangement portion that is a planar portion for placing a solar cell panel and a groove-shaped flange portion formed at a position adjacent to the solar cell arrangement portion are integrated. A substrate (frame) is disclosed.
That is, the solar cell module disclosed in Patent Document 1 is formed by attaching a solar cell panel to this base material, and has a groove-like rain gutter extending in the eaves-ridge direction at one end in the longitudinal direction. Are integrally formed. That is, the solar cell module disclosed in Patent Document 1 is a rain gutter integrated solar cell module in which gutters are integrally formed.

JP 2009-299465 A

Here, when laying a gutter-integrated solar cell module (hereinafter also simply referred to as a solar cell module) on the roof, the eave side end of the eaves is another solar cell module located on the eave side. Or above roof members such as tiles and at positions sufficiently away from the ridge end portions on the eaves side.
According to such an arrangement, when the rainwater that has flowed through the eaves part of the solar cell module located on the ridge side flows out further from the eaves end portion of the eave part to the eaves side, another solar cell module or roof member located on the eave side. It flows out to the upper surface of the solar cell module and flows as it is toward the eaves side through the upper surfaces of other solar cell modules and roof members.

On the other hand, if the eaves side end of this eaves part is located near the ridge side end of another solar cell module or roof member located on the eave side, the solar cell module or roof member ridge side There is a possibility that rainwater flows into the roof base side from the gap formed in the vicinity of the end.
Explaining in detail, there is a slight gap between the solar cell modules adjacent to each other in the eaves building direction and the boundary between the solar cell modules and the roof member. May be. Therefore, if the eaves side end of the eaves portion that becomes the outflow portion of rainwater is located in the vicinity of this gap, rainwater may flow from this gap to the roof base side.

By the way, on the roof of the building where the solar cell module is laid, tiles (roof members) may be laid together with the solar cell module, and the type of tiles laid together at this time is appropriately selected for each building. Become. As a specific example, when a solar cell module is laid on a part of the roof and a flat roof tile is laid on the other part, or a solar cell module is laid on a part of the roof and a sheet metal roof is laid on the other part. There is a case to do. These are all mixed with a solar cell module and one type of roof tile, and the types of roof tiles to be laid are different.
When the types of tiles laid on the roof are different, the working length (the length of the portion excluding the portion overlapping with other tiles at the time of installation) may be different for each type. For example, there are cases where the working length differs between a flat roof tile and a sheet metal roof tile. Furthermore, even when the same tile is laid, it may be laid so that the working length is different when laying on the roof. For example, when a sheet metal tile is laid around the solar cell module, it may be laid to have a normal working length, or the same sheet metal tile is laid to have a longer (or shorter) working length than usual. That happened.

For this reason, there has been a problem that the length of the eaves portion of the rain gutter integrated solar cell module laid on the roofs of various buildings cannot be made uniform.
To explain specifically with an example, according to the normal working length of the flat roof tiles laid together, the eaves end portion of the eaves is set to be arranged at the appropriate position described above, on the roof When a solar cell module is laid on a part and a flat roof tile is laid on the other part with a normal working length, a rain gutter integrated solar cell module can be laid without any problem.
However, when a sheet metal roof tile is laid together with a solar cell module having the same setting of the collar part, the length of the collar part is insufficient, and another solar cell module in which the eaves end part of the collar part is located on the eaves side Or in the vicinity of the ridge end portion of the roof member.

In other words, if the normal working length of the flat roof tile and the normal working length of the sheet metal roof are slightly different, it becomes possible to appropriately lay the solar cell module having the same setting collar portion with some adjustment. There is a case. However, if the normal working length of a flat roof tile is substantially different from the actual working length of a sheet metal roof, as in the case where a sheet metal roof is installed with a different working length, the solar gutter integrated solar It was necessary to change the length of the battery module cage.
In other words, the length of the ridge portion of the rain gutter integrated solar cell module may have to be changed according to the working length of the roof member laid together.

However, if the length of the ridge portion of the solar cell module integrated with the rain gutter is not made uniform, and the length is appropriately changed, mass production of the solar cell module becomes difficult. Manufacturing cost will be high.
That is, when manufacturing a solar cell module, it is preferable to manufacture a large amount of the same specifications in order to reduce the manufacturing cost. On the other hand, when manufacturing solar cell modules having different ridge lengths according to the working lengths of the roof members laid together, solar cell modules having different specifications are manufactured, which increases production efficiency. Therefore, the manufacturing cost is inevitably increased.

  Moreover, in the solar cell module 3 of this embodiment, as shown in FIG. 6, it is possible to extend the length of the rainwater flow path by integrally attaching the eaves extension member 65 to the eaves portion 22. It has become. In other words, the rainwater flow path is formed by the eaves part 22 and the eaves extension member 65, so that the rainwater flow path is longer in the front-rear direction (eave building direction) than when the rainwater flow path is formed only by the eaves part 22. Can be formed.

  As shown in FIG. 7, the eaves extending member 65 is formed on a flat bottom plate forming portion 70 (extension side bottom plate portion) extending in the front-rear direction (eave building direction) and one end side in the short direction of the bottom plate forming portion 70. The inner side wall portion 71 (extended side wall portion) located and the outer side wall portion 72 (extended side wall portion) located on the other end side are provided.

At the front end (eave side end) of the bottom plate forming portion 70, an extension hook retaining portion 73 (hanging) formed by bending the front end side of the bottom plate forming portion 70 downward and further bending the lower end side rearward. Stop) is formed. In other words, the extended hook latching portion 73 is a portion that extends downward from the front end of the bottom plate forming portion 70 and then extends to the rear side.
That is, the extended hook latching portion 73 includes a vertical plate-like connecting plate portion 73a extending downward from the front end side of the bottom plate forming portion 70 and a flat plate-like latching plate body portion 73b extending rearward from the lower end of the connecting plate portion 73a. And. In other words, it can be said that the extended hook locking portion 73 is a hook-like portion that is bent so that the side view shape is substantially “L” shape.

The inner side wall portion 71 is formed by bending one end of the bottom plate forming portion 70 in the short direction upward, and is a vertical plate-like portion protruding upward from the bottom plate forming portion 70.
The inner side wall portion 71 is a portion that forms one of two side wall portions that are positioned in the lateral direction of the heel extension member 65 and are opposed to each other, and is attached to the heel portion 22 as shown in FIG. Sometimes a side wall portion located on the solar cell module main body 63 side is formed. That is, the inner side wall portion 71 is a portion protruding upward from the inner end portion in the short direction of the bottom plate forming portion 70.

As shown in FIG. 7, the outer side wall 72 is bent upward at one end in the short direction of the bottom plate forming portion 70, and further, the upper end portion is directed toward the center side in the short direction of the bottom plate forming portion 70. It is formed by bending.
That is, the outer side wall portion 72 includes an upright plate-like side wall forming plate portion 72a that protrudes upward from one side end portion in the short direction of the bottom plate forming portion 70, and the other end portion (inner side from the upper end of the side wall forming plate portion 72a. And a flat plate-like restricting plate portion 72b (regulating piece portion) that protrudes toward an end portion where the side wall portion 71 is located.

  The outer side wall portion 72 is a portion that forms one of two side wall portions that are positioned in the lateral direction of the eaves extension member 65 and are opposed to each other. As shown in FIG. Sometimes a side wall portion located outside the solar cell module main body 63 is formed. That is, the outer side wall portion 72 is a portion that is continuous with the outer end portion in the short direction of the bottom plate forming portion 70.

In this eaves extending member 65, it is a space formed above the bottom plate forming portion 70, and is an extended inner groove shape that is a space surrounded by the bottom plate forming portion 70, the inner side wall portion 71, and the outer side wall portion 72. The space 74 functions as a flow path for flowing rainwater.
The extended inner groove-like space 74 is a groove-like space extending in the front-rear direction. In other words, in a state where the solar cell module 3 is mounted on the roof portion 22 of one solar cell module 3 and installed on the roof (details will be described later), a groove-like space extending in the eaves-ridge direction is formed. Yes.
This extended inner groove-like space 74 is formed inside the eaves extension member 65 and is a space for flowing rainwater from the ridge side (rear side) to the eaves side (front side).

Here, as described above, the heel extension member 65 is a heel extension member for a solar cell module that can be attached to the heel portion 22 of the solar cell module 3 (see FIG. 6).
That is, as shown in FIG. 6, the eaves extension member 65 can be integrally attached to the eaves portion 22 by being fitted into the eaves portion 22 from the front (eave side). In other words, by attaching at least a part of the flange portion 22 to the extended inner groove-like space 74 that is the inner space of the flange extension member 65, the attachment to the flange portion 22 is possible.

At this time, the entire length of the rainwater flow path (hereinafter also simply referred to as the rainwater flow path 80) formed by the collar 22 and the collar extension member 65 is varied by varying the insertion length of the collar 22. be able to.
The rainwater flow passage 80 is a space in which a part of the inner groove-like space 24 and the extended inner groove-like space 74 are continuous in the front-rear direction and extend in the groove shape along the front-rear direction (eave building direction). .

Specifically, for example, the heel extension member 65 is slid to the front side (eave side) from the state where the entire ridge portion 22 is inserted into the extended inner groove-like space 74 (see FIG. 6B). Only the front side portion including the front end of the flange portion 22 is inserted into the extended inner groove-like space 74. In this case, the distance of the rainwater flow passage 80 is increased by the distance moved by sliding.
That is, it is possible to vary the overall length of the rainwater flow passage 80 by varying the length of the overlapping portion of the collar portion 22 and the collar extension member 65 that overlap in the vertical direction.

More specifically, when the collar portion 22 is inserted into the inner space of the collar extension member 65, only the front side portion including the front end of the collar portion 22 or the entire collar portion 22 is inserted into the extended inner groove-shaped space 74. Will be. That is, a portion including at least a part on the front side (eave side) of the collar portion 22 is inserted.
At this time, in the portion of the collar portion 22 inserted into the extended inner groove-like space 74, an overlapping portion is formed in which the collar portion 22 and the collar extension member 65 overlap in the vertical direction. That is, a part of the heel extension member 65 is located below at least a part of the heel part 22, in other words, a part of the heel extension member 65 is located outside at least a part of the heel part 22. Yes. Therefore, paying attention to each part of the overlapping portion, the heel bottom plate portion 22a overlaps the bottom plate forming portion 70 of the heel extension member 65 in the vertical direction, and the inner heel side wall portion 22d is connected to the inner side wall portion 71 of the heel extension member 65. The outer heel side wall portion 22c is overlapped with the outer side wall portion 72 of the heel extension member 65 in the left and right direction.
In other words, the portion of the collar portion 22 that is inserted into the inner space of the collar extension member 65 is a part surrounded by the collar extension member 65 on the lower side, the inner side, and the outer side.

Therefore, as the length of the portion of the collar portion 22 inserted into the extended inner groove-like space 74 is shortened, the overall length (length in the front-rear direction) of the rainwater flow passage 80 is increased. In other words, the total length of the rainwater flow passage 80 is calculated based on the sum of the length of the collar portion 22 (length in the front-rear direction) and the length of the collar extension member 65 (length in the front-rear direction). It is a value obtained by subtracting the length of 65 overlapping portions (length in the front-rear direction). And since the length of the part inserted in the inner space of the collar extension member 65 in the collar part 22 is also the length of the overlapping part of the collar part 22 and the collar extension member 65, the part inserted in the inner space is short. As a result, the entire length of the rainwater flow passage 80 becomes longer.
When the length of the portion inserted into the inner space of the eaves extension member 65 is increased, the length of the rainwater flow passage 80 is reduced, but the eaves portion 22 and the eaves extension member 65 are firmly attached (dropped off). Difficult state).

Further, the collar portion 22 of the present embodiment has a shape that fits almost exactly when inserted into the inner space of the collar extension member 65. In other words, at the overlapping portion of the collar portion 22 and the collar extension member 65, at least a part of the collar portion 22 and a part of the collar extension member 65 are in close contact with each other.
That is, the width (length in the left-right direction) of the bottom plate forming portion 70 of the heel extension member 65 is slightly longer than the width (length in the left-right direction) of the heel bottom plate portion 22a of the heel portion 22. Further, the vertical length of the outer side wall portion 72 of the eaves extension member 65 is longer than the vertical length of the outer side wall portion 22c of the eaves bottom plate portion 22a. Specifically, the length of the side wall forming plate portion 72a is longer than the length of the outer side wall side wall portion 22c in the vertical direction.
From the above, when the collar part 22 is inserted into the inner space of the collar extension member 65, the bottom surface of the collar bottom plate part 22a in the collar part 22 and the upper surface of the bottom plate forming part 70 in the collar extension member 65 are in close contact with each other. Become. Similarly, the outer side surface of the inner side wall side wall portion 22d of the flange portion 22 and the inner side surface of the inner side wall portion 71 of the flange extension member 65 are in close contact with each other, and the outer side surface of the outer side wall side wall portion 22c of the flange portion 22 The inner side surface of the outer side wall portion 72 of the extension member 65 is in close contact.

In addition, the front inclination part 46 (refer FIG. 6 etc.) of the collar part 22 is formed by slightly bending the front-end part (eave side edge part) of the collar bottom board part 22a below as mentioned above. .
Therefore, the front inclined portion 46 is a portion that can be elastically deformed. When the heel extension member 65 is attached, the front inclined portion 46 is deformed by attaching the bottom plate forming portion 70 of the heel extension member 65 from the lower side. The shape extends to the front side along the upper surface of the bottom plate forming portion 70. In other words, the deformed lower surface of the front inclined portion 46 and the upper surface of the bottom plate forming portion 70 are in close contact (or substantially in close contact).

Further, in a state where the collar portion 22 is inserted into the inner space of the collar extension member 65, the regulation plate portion 72 b functions as a regulation section for regulating the downward movement of the collar extension member 65.
That is, in the state where the heel extension member 65 is attached to the heel part 22, even if the heel extension member 65 attempts to drop downward due to gravity or the like, the lower surface of the restriction plate part 72 b of the heel extension member 65 is The movement is regulated by coming into contact with the upper end of the outer flange side wall portion 22c. As a result, it is possible to prevent the eaves extension member 65 from falling off, and the solar cell module 3 can be carried with the eaves extension member 65 attached to the eaves portion 22.

As shown in FIGS. 8 and 9, the tile member 4 is a roof plate formed by appropriately bending a metal plate, and the eaves side tile hooking portion 85 (roof material eaves) located below the eave end side. Side latching portion), a flat tile body plate portion 86, and a ridge side tile latching portion 87 (roof material ridge side latching portion). In addition, a tile mounting hole 88 is provided in a portion located slightly ahead of the rear end portion (ridge side end portion) of the tile member 4 in order to fix the tile member 4 on the roof. A plurality (two in FIG. 8) of the tile mounting holes 88 are formed, and are formed so as to be arranged in parallel at intervals in the left-right direction.
Furthermore, as shown in FIG. 9, an under-tile foam heat insulating material 89 is attached to the back surface of the tile main body plate portion 86.

The eaves side tile retaining portion 85 is a portion formed by bending the front end side (eave end side) of the tile main body plate portion 86 downward and further bending the lower end side rearward.
That is, the eaves side tile hooking portion 85 includes a vertical plate-like portion extending downward from the front end side of the tile main body plate portion 86 and a flat plate-like portion extending rearward from the lower end of the vertical plate-like portion. It is a bowl-shaped portion that extends downward and then extends backward.

Each of both end portions in the left-right direction of the tile main body plate portion 86 is provided with a standing-plate-like roof tile side wall portion 90 formed by bending an end portion in the left-right direction downward.
The tile side wall 90 has a lower end that is higher than the lower end of the eaves side tile hook 85 and is located slightly rearward (ridge side) from the front end (eave end) of the tile member 4. To a portion located slightly forward of the rear end of the roof tile member 4.

  The ridge-side tile hooking portion 87 is a portion formed by bending a part of a metal plate so as to be convex on the front side, and in the front and back direction of the roof tile member 4, the direction from the back side to the front side. A protruding plate-like protruding wall portion 87a formed so as to protrude in the direction from the lower side to the upper side, and formed so as to protrude in the direction from the upper end of the protruding wall portion 87a toward the front side (eave side). It has a structure provided with a flat upper plate part 87b. That is, the ridge-side tile retaining portion 87 has a substantially “L” shape when viewed from the side, and is a portion extending in the left-right direction.

As shown in FIG. 9, the under-tile foam heat insulating material 89 is formed by appropriately covering the surface of a foamed resin member with an aluminum film or the like, and has a substantially rectangular parallelepiped shape. More specifically, the under-foam foam heat insulating material 89 is formed so that its thickness becomes thinner toward the rear side (ridge side), and is positioned above the front end side (eave end side). The corner portion to be cut off is formed into a rounded shape, and the inclined portion is formed by removing the corner portion positioned above the rear end side (ridge end side).
Further, the under-brick foam heat insulating material 89 has a shape in which a portion on one end side in the longitudinal direction (left-right direction) of the roof tile member 4 is omitted. That is, the under-brick foam heat insulating material 89 extends from a position slightly distant from the one end portion in the longitudinal direction to a position reaching the vicinity of the other end portion. In other words, the one end portion in the longitudinal direction of the under-tile foam heat insulating material 89 is located slightly closer to the center side than the one end portion in the longitudinal direction of the tile member 4, and the other end in the longitudinal direction of the under-tile foam heat insulating material 89. The end portion is located in the vicinity of the other end portion in the longitudinal direction of the roof tile member 4 (arranged at substantially the same position).
That is, the under-brick foam heat insulating material 89 is arranged from the other end portion in the left-right direction of the tile member 4, and the under-brick foam heat insulating material 89 is attached around one end portion in the longitudinal direction of the tile member 4. A buttocks arrangement area 91 that is not a part is formed.

  The collar part arrangement | positioning area | region 91 is a part formed between the one side edge part of the under-brick foam heat insulating material 89, and the tile side wall part 90, The length of the left-right direction (width direction) of the collar part 22 mentioned above It is slightly longer than the length in the left-right direction. More specifically, the length in the left-right direction (width direction) is the left-right direction (width direction) of the rainwater flow passage 80 (see FIG. 6 and the like) formed by attaching the heel extension member 65 to the heel portion 22. It is slightly longer than the length of. In this collar part arrangement | positioning area | region 91, the thickness is thinner than the part to which the under-sill foam insulation material 89 was attached.

  Then, the roof structure 1 of this embodiment is demonstrated in detail along a construction procedure.

  First, as shown in FIG. 10, a process of attaching the eaves edge fitting 2 to the eaves side end of the roof base 95 is performed. For the sake of drawing, only a part of the eaves metal fitting 2 is given a reference numeral, and the other reference numerals are omitted.

The roof foundation 95 is attached to a roof surface of a building to be laid at a predetermined angle by a roofing material (not shown) such as an eaves drain (not shown) or a waterproof sheet, and further, a vertical pier (not shown), A horizontal crosspiece 97 and Hirokomai 98 (not shown in FIG. 10, refer to FIG. 11) are attached and formed.

  In the present embodiment, as shown in FIG. 10, a plurality of eaves-end fittings 2 are fixed in parallel along the left-right direction (the column direction).

Then, the process of fixing the tile member 4 and the solar cell module 3 which belong to the eaves side 1st step with respect to the roof base | substrate 95 which attached the eaves-end metal fitting 2 is implemented.
When fixing the roof tile member 4 belonging to the first eaves side first stage, as shown in FIG. 12, the roof side tile latching portion 85 (see FIG. 8, etc.) of the roof tile member 4 is attached to the plurality of eaves end brackets 2. It is assumed that the eaves side portion of the roof tile member 4 is hooked on the plurality of eaves end fittings 2 through the hooking space 17 (see FIG. 11). In other words, the eaves side portion of the roof tile member 4 is in a state of being hooked to the eaves tip metal fitting 2 which is an external member. And the ridge side part is rotated in the direction which goes below using the eaves side part of the tile member 4 as a rotation fulcrum. Further, when the tile member 4 is moved to the installation position by sliding in the column direction (left and right direction), the fastening element is inserted into the ridge side portion and fixed on the roof base 95.
That is, after the slide movement, as shown in FIG. 13, the tile mounting holes 88 of the roof tile member 4 are overlapped with the cross beams 97, and the fastening elements are inserted through these to make the roof tile 95 the roof tile 95. Fasten together on top.

When the solar cell module 3 belonging to the first eave side first stage is fixed, as shown in FIG. 14, a plurality of module eaves side latching portions 50 (see FIGS. 3 and 5) of the solar cell module 3 are provided. It is inserted into the hooking space 17 (see FIG. 11) of the eaves-end fitting 2 and is hooked on the eaves-end fitting 2. At this time, the extended hook locking portion 73 (see FIG. 6 and the like) located at the eaves end of the rainwater flow passage 80 is also in a state of being hooked to the eaves fitting 2 as necessary. That is, it is set as the state which hooked the eaves side part of the solar cell module 3 on the eaves tip metal fitting 2 which is an external member. And the eaves side part of the solar cell module 3 is made to rotate in the direction which a ridge side part goes to the downward direction using a rotation fulcrum. Further, when the solar cell module 3 is moved to the installation position by sliding in the column direction (left and right direction), the fastening element is inserted into the ridge side portion and fixed on the roof base 95.
More specifically, after the slide movement, a mounting hole (not shown) formed in the pressing plate member 33 and the horizontal crosspiece 97 overlap each other in the vertical direction, and a fastening element is inserted through these, so that the solar cell The module 3 is fixed integrally on the roof base 95.

In this manner, the roof tile member 4 and the solar cell module 3 belonging to the first eave side first stage are fixed.
Here, in the first stage on the eaves side of the roof structure 1 in the present embodiment, as shown in FIG. 1 and the like, the roof tile members 4 are fixed to both outer sides in the crossing direction, and a plurality of solar cell modules 3 are interposed therebetween. It is structured to be fixed in a state of being aligned in the column direction.

  Therefore, as shown in FIG. 15 and FIG. 16, after fixing the first solar cell module 3 a in the first stage on the eave side, the second solar cell is positioned adjacent to the left and right direction (column direction). The battery module 3b is fixed. The second solar cell module 3b is also fixed in the same procedure as the fixing of the first solar cell module 3a described above.

Here, when attention is paid to a portion (for example, a portion indicated by A1 in FIG. 16) serving as a boundary between the first solar cell module 3a and the second solar cell module 3b, the first solar cell module 3a. As shown in FIG. 16, the rainwater flow passage 80 (see FIG. 15) including the flange portion 22 is located below the second solar cell module 3 b.
Specifically, the rainwater flow path 80 belonging to the first solar cell module 3a is in a state of being housed in the heel arrangement region 58 (see FIG. 4) of the second solar cell module 3b.

From this, as shown in FIG. 17, the front cover 31 (front protection) of the second solar cell module 3b is located further on the eaves side than the eaves end of the rainwater flow passage 80 belonging to the first solar cell module 3a. The plate portion 48) is located, and the solar cell module main body 63 of the second solar cell module 3b is located further above the upper end.
That is, the front (eave side) and the upper side of the rainwater flow passage 80 belonging to the first solar cell module 3a are covered with the second solar cell module 3b arranged adjacent to each other, and almost all This part has a structure that is not exposed to the outside. In other words, the second solar cell is located above and in front of the entire area from the rear end (ridge side end) to the front end (eave side end) of the rainwater flow passage 80 belonging to the first solar cell module 3a. The battery module 3b (solar cell module main body 63) is positioned.

Subsequently, as shown in FIG. 18 and FIG. 19, the third solar cell module 3c is fixed to a position adjacent to the second solar cell module 3b, and further, the third solar cell module 3c The second roof tile member 4 is fixed at an adjacent position.
At this time, the third solar cell module 3b is also fixed in the same procedure as the fixing of the first solar cell module 3a, and the second tile member 4b is also fixed to the above-described tile member. 4 (first roof tile member 4a) is fixed in the same procedure.

  At this time, at the boundary portion between the second solar cell module 3b and the third solar cell module 3c, there are also three rainwater flow passages 80 belonging to the second solar cell module 3b as described above. It is in the state of being housed in the buttocks arrangement region 58 (see FIG. 4) of the solar cell module 3c of the eye.

When attention is paid to a portion (for example, a portion indicated by A2 in FIG. 19) serving as a boundary between the third solar cell module 3c and the second roof tile member 4b, as shown in FIG. The rainwater flow path 80 including the flange portion 22 of the solar cell module 3c is located below the second roof tile member 4b.
Specifically, the rainwater flow path 80 belonging to the third solar cell module 3c is in a state of being housed in the heel arrangement region 91 (see FIG. 9) of the second roof tile member 4b.

From this, as shown in FIG. 20, the eaves-side tile hooking portion 85 of the second tile member 4b is further on the eaves side than the eaves end of the rainwater flow passage 80 belonging to the third solar cell module 3c. The tile main body plate portion 86 of the second tile member 4b is located further above the upper end.
That is, the front (eave side) and upper side of the rainwater flow passage 80 belonging to the third solar cell module 3c are covered with the second tile member 4b arranged adjacent to each other, and almost all The structure is such that the portion is not exposed to the outside. In other words, the second tile is located above and in front of the entire area from the rear end (ridge side end) to the front end (eave side end) of the rainwater flow passage 80 belonging to the third solar cell module 3c. The member 4b is in a positioned state.

  This completes the process of fixing the roof tile member 4 and the solar cell module 3 belonging to the first eaves side. Following this, a step of fixing the roof tile member 4 and the solar cell module 3 belonging to the second eave side stage is performed.

When fixing the roof tile member 4 belonging to the eaves-side second stage, for example, as shown in FIG. It is set as the state hooked on the ridge side tile latching part 87 of the tile member 4a belonging to the first side of the side and the module ridge side latching part 59 of the solar cell module 3a belonging to the first stage of the eaves side. That is, a part of the eaves side tile hooking portion 85 is hooked on the ridge side tile hooking portion 87 and the other part is hooked on the module ridge side hooking portion 59.
Then, the eaves side portion of the roof tile member 4c belonging to the eaves side second stage is rotated in the direction in which the ridge side portion is directed downward, with the rotation side fulcrum as a rotation fulcrum. Furthermore, when the tile member 4c belonging to the eave side second stage is moved to the installation position by sliding in the column direction (left and right direction), a fastening element is inserted into the ridge side portion and fixed on the roof base 95. To do.
That is, after the eaves-side tile hooking portion 85 is hooked on an external member, rotated, and further slid, as shown in FIG. 22, the tile attachment hole 88 of the tile member 4c is overlapped with the horizontal beam 97. The tile member 4c is integrally fixed on the roof base 95 by inserting fastening elements through them.

When fixing the solar cell module 3 belonging to the eaves-side second stage, for example, as shown in FIG. 23, the module eaves side latching portion 50 ( 3, FIG. 5, etc.) are hooked on the module building side latching portion 59 of two solar cell modules 3 (solar cell module 3 a, solar cell module 3 b) that are adjacently arranged in the first eave side. And That is, a part of the module eaves side latching part 50 is hooked on the module building side latching part 59 of one solar cell module 3a, and the other part of the module eaves side latching part 50 is hooked on the other solar cell module. It is assumed that it is hooked on the module building side latching portion 59 of 3b.
Then, the eaves-side portion of the solar cell module 3 belonging to the eave-side second stage is rotated in the direction in which the ridge-side portion is directed downward, using the rotation fulcrum as a rotation fulcrum. Further, when the solar cell module 3 is moved to the installation position by sliding in the column direction (left and right direction), the fastening element is inserted into the ridge side portion and fixed on the roof base 95 (see FIG. 24).
More specifically, after the module eaves side latching part 50 is hooked on the external member, rotated, and further slid, the mounting hole (not shown) formed in the pressing plate member 33, the cross beam 97, Are overlapped in the vertical direction, and a fastening element is inserted through them to fix the solar cell module 3 integrally on the roof base 95.

As described above, in the step of fixing the roof tile member 4 and the solar cell module 3 belonging to the second stage of the eaves side, in the position where they are rotated, in other words, in the position shifted in the direction of the column from the installation position. The eaves side portion is hooked on the roof tile member 4 and the solar cell module 3 fixed on the side, and then rotated. In other words, in the first stage on the eaves side, the state is hooked and rotated with respect to a group composed of the tile member 4 and the solar cell module 3 arranged adjacent to each other or a group composed of the two solar cell modules 3.
Therefore, as will be described in detail later, in the case where two roof tile members 4 are arranged adjacent to each other in the first row of the eaves side, the roof tile members 4 and the solar cell modules 3 belonging to the second stage of the eaves side are arranged. The eaves side end may be hooked on the two roof tile members 4 and rotated. That is, at the position where the roof tile member 4 and the solar cell module 3 belonging to the second eave side are rotated, one or more of the roof tile member 4 and the solar cell module 3 located on the eave side are provided. What is necessary is just to make it the state hooked with respect to the member, and to rotate after that.

  Here, as shown in FIG. 1 and the like, the roof member 1 of the roof structure 1 of the present embodiment also has the roof member 1 on the eaves side second stage, and the roof tile members 4 are fixed to both outer sides in the crossing direction, and a plurality of solar cell modules 3 are interposed therebetween. Are fixed in parallel.

  Therefore, similarly to the first stage on the eave side, after fixing the first roof tile member 4c in the second stage on the eave side, a plurality of solar cell modules 3 are fixed in order from one end side in the row direction. Then, the second roof tile member 4d is fixed.

In addition, in the roof structure 1 of this embodiment, the two tile members 4 adjacent in the eaves ridge direction (roof inclination direction) are attached in a state where both end positions in the row direction (left and right direction) are aligned. That is, above the roof tile member 4a located on the first eave side, the roof tile member 4c located on the second eave side is located, and both ends of the roof tile member 4a in the row direction are located. Each of the both ends of the roof tile tile 4c in the direction of the row is located at a position adjacent to each of the sections on the ridge side.
Similarly, the both end positions in the column direction of the solar cell modules 3 adjacent in the eaves-ridge direction are also aligned.

  Here, as shown in FIG. 24 and FIG. 25, in the state where the first solar cell module 3 d in the second eave side second stage is arranged at the installation position, the solar cell module main body of this solar cell module 3 d On one side of the eave 63, one of the two solar cell modules 3 (solar cell module 3a) adjacently disposed in the first eave side is located. On the other hand, the other of the two solar cell modules 3 (solar cell module 3b) is located at the eaves end of the rainwater flow passage 80 of the solar cell module 3d.

That is, the module eaves side latching part 50 (refer FIG. 3 etc.) of the 1st solar cell module 3d in the eaves side 2nd step | paragraph is one solar cell module 3a adjacently arranged by the eaves side 1st step | paragraph. The module building side latching portion 59 (see FIG. 23, etc.).
Then, as shown in FIG. 25, the extended rod hooking portion 73 of the solar cell module 3d is hooked to the module building side hooking portion 59 of the other solar cell module 3b that is adjacently disposed. In other words, the extended hook latching portion 73 is latched to the module building side latching portion 59 which is an external member.

If the solar cell module 3a at the first eave side is used as a reference, the solar cell module 3d on the ridge side is an external member of the solar cell module 3a. That is, it can be said that the module eaves side latching part 50 of the solar cell module 3d, which is an external member, is latched to the module building side latching part 59 of the eaves side first stage solar cell module 3a. .
Similarly, it can be said that the extended hook latching portion 73 of the solar cell module 3d, which is an external member, is latched to the module building side latching portion 59 of the solar cell module 3b on the eaves side first stage. .

  As a result, the eaves-side end of the rainwater flow passage 80 of the first solar cell module 3d in the eave-side second stage is away from the ridge-side end of the solar cell module 3b adjacent to the eaves. Yes, specifically, it is fixed to the upper side of the position near the eave end portion of the pressing plate member 33 of the solar cell module 3b adjacent to the eave side.

Subsequently, as shown in FIG. 26 and FIG. 27, the second solar cell module 3e is fixed at a position adjacent to the first solar cell module 3d, and the second solar cell module 3e The third solar cell module 3f is fixed at an adjacent position.
At this time, these solar cell modules 3 (solar cell module 3e and solar cell module 3f) are also fixed in the same procedure as the fixing of the solar cell module 3d described above.

  Here, attention is paid to a portion that becomes a boundary between the two solar cell modules 3 in the second stage on the eaves side. As shown in FIG. 24 and FIG. 26, the rainwater flow path 80 of the first solar cell module 3d is provided at the boundary between the first solar cell module 3d and the second solar cell module 3e. (Refer FIG. 24) It has been in the state located under the 2nd solar cell module 3e (refer FIG. 26). That is, the rainwater flow path 80 belonging to the first solar cell module 3d is in a state of being accommodated in the heel arrangement region 58 (see FIG. 4) of the second solar cell module 3e.

That is, similarly to the boundary portion between the two solar cell modules 3 (the solar cell module 3a and the solar cell module 3b) in the first stage on the eaves side, the rear end (building) of the rainwater flow passage 80 belonging to one solar cell module 3d. The other solar cell modules 3e arranged adjacent to each other in the row direction are located above and in front of the entire region from the side end) to the front end (eave end).
That is, as shown in FIG. 28, in the eave side second stage, the module eaves side hooking portion 50 and the extended eaves hooking portion 73 that are the eaves side portion of the solar cell module 3 are not the eaves end bracket 2, This is different from the first eave side first stage in that the solar cell module 3 located on the eaves side is hooked to the module building side latching portion 59. However, as in the first stage on the eaves side, the rainwater flow passage 80 is covered with the solar cell modules 3 arranged adjacent to each other in the row direction so that the rainwater flow passage 80 is not exposed to the outside.

  Similarly, the rainwater flow path 80 belonging to the second solar cell module 3e is also the third solar cell at the boundary between the second solar cell module 3e and the third solar cell module 3f. The battery module 3f is in a state of being housed in the collar part arrangement region 58 (see FIG. 4).

  Here, as shown in FIG. 27, in the state where the third solar cell module 3f in the second stage on the eave side is arranged at the installation position, the eaves of the solar cell module main body 63 of this solar cell module 3f. On the side, the solar cell module 3c arranged in the first stage on the eave side is located. On the other hand, the roof tile member 4b arranged at the eave side first stage is located at the eaves end of the rainwater flow passage 80 of the solar cell module 3f.

  That is, the module eaves side hooking portion 50 (see FIG. 3 and the like) of the third solar cell module 3f in the second eave side has the roof tile and the solar cell module 3c arranged adjacent to each other in the first eave side. Among the members 4, the module 4 is hooked on a module ridge side hooking portion 59 (see FIG. 23 and the like) formed on the solar cell module 3c. Then, as shown in FIG. 29, the extended rod hooking portion 73 of the solar cell module 3f is hooked to the ridge side roof tile hooking portion 87 formed on the roof tile member 4b. In other words, the ridge side tile hooking portion 87 is in a state in which the extended hook hooking portion 73 that is an external member is hooked.

  Accordingly, the eaves side end of the rainwater flow passage 80 of the third solar cell module 3f in the second eave side is a position away from the ridge side end of the tile member 4b adjacent to the eaves. Specifically, it is fixed to the upper side of the tile main body plate portion 86 of the tile member 4b adjacent to the eaves side.

Subsequently, as shown in FIG. 30, the second roof tile member 4d in the second eave side is fixed to a position adjacent to the third solar cell module 3f in the second eave side.
The roof tile member 4d is fixed by the same procedure as that for fixing the roof tile member 4 (first roof tile member 4b).

Here, when attention is paid to a portion that becomes a boundary between the third solar cell module 3f and the second roof tile member 4d, as shown in FIG. 31, the flange portion 22 of the third solar cell module 3f is included. The rainwater flow passage 80 is located below the second tile member 4d.
Specifically, the rainwater flow passage 80 belonging to the third solar cell module 3f is in a state of being housed in the heel arrangement region 91 (see FIG. 9) of the second roof tile member 4d.

That is, like the boundary portion between the solar cell module 3c and the roof tile member 4b in the first stage on the eaves side, from the rear end (ridge side end) of the rainwater flow passage 80 belonging to one solar cell module 3d to the front end (eave The roof tiles 4b are arranged adjacent to each other in the direction of the rows in the upper part of the entire area up to the side end part) and in front of it.
That is, as shown in FIG. 31, in the second stage of the eaves side, the eaves side portion of the solar cell module 3 f is not the eaves end fitting 2, but the module building side latching portion of the solar cell module 3 c located on the eave side. 59 and the eaves-side first stage is different in that it is hooked to the ridge-side tile hooking portion 87 of the roof tile member 4b located on the eaves side. However, as in the first stage on the eaves side, the rainwater flow passage 80 is covered with the roof tile members 4b arranged adjacent to each other in the direction of the beam so that the rainwater flow passage 80 is not exposed to the outside.

  With the above, the process of fixing the roof tile member 4 and the solar cell module 3 belonging to the second eave side is completed. Thereafter, similarly, a step of fixing the roof tile member 4 and the solar cell module 3 belonging to the eaves-side third and subsequent stages for each stage is performed. In addition, a roof structure 1 as shown in FIG. 1 is formed by attaching a decorative member or the like (not shown) to the ridge side of the step located closest to the ridge side as necessary.

In the above-described first embodiment, the rainwater flow passage 80 is formed by inserting the collar portion 22 into the inner space of the collar extension member 65 and positioning the collar extension member 65 on the lower side of the collar portion 22. However, the present invention is not limited to this.
A heel extension member that is smaller than the heel extension member 65 of the first embodiment described above is formed, the heel extension member is inserted into the inner space of the heel portion 22, and the heel portion 22 is positioned below the heel extension member. A rainwater flow passage may be formed. In this case, the restriction piece portion may be formed not on the side wall portion of the heel extension member but on the side wall portion of the heel portion 22.

  In the above-described embodiment, an example in which a plurality of module building side latching portions 59 are formed in the eaves side portion of the solar cell module 3 is shown, but the present invention is not limited to this. You may provide only one module ridge side latching part long in the column direction. In this case, it may extend from one end in the column direction to the other end.

In the above-described embodiment, both ends of the two tile members 4 adjacent in the eave building direction (the inclination direction of the roof) are aligned in the row direction, and both ends in the row direction of the solar cell modules 3 adjacent in the eave building direction are aligned. Although the example of the roof structure 1 laid with the same position is shown, the present invention is not limited to this.
For example, the solar cell module 3 located on the ridge side may be formed such that the center portion in the row direction is located on the ridge side of the boundary portion between two solar cell modules 3 that are adjacently arranged on the eave side in the row direction. Good. That is, it is not necessary to arrange the both end positions in the column direction of the solar cell modules 3 adjacent in the eaves-ridge direction. According to such a configuration, it becomes possible to arrange the rainwater flow passage 80 of the solar cell module 3 located on the ridge side at a position far from the boundary portion between the two solar cell modules 3 that are adjacently arranged on the eaves side. . As described above, when the rainwater flow passage 80 is arranged at a position away from the boundary portion between the two members laid on the roof, the rainwater intrusion into the roof base 95 from the gap that may be formed in the boundary portion is prevented. Since it can prevent more reliably, it is preferable.
