The seal piece 112 has an L-shaped cross section and is attached to the second flat plate portion 87 and the second step portion 88.

Next, the construction method of the roof structure 1 of this embodiment is demonstrated. In order to construct the roof structure 1 of the present embodiment, the first roof base is formed, and the slate tiles 2 are arranged in a row and in a plurality of stages on the roof structure 1 so as to have a planar spread. And when installing this slate roof tile 2, the eaves edge attachment metal fitting (eave edge attachment tool) 5 and the intermediate attachment metal fitting (attachment tool) 6 are attached.
That is, in this embodiment, the foundation roof structure 3 is constructed prior to the installation of the solar cell module 10.

The specific procedure is as follows.
That is, as shown in FIG. 16, the eaves drainage 68 of the normal slate tile 2 is installed at the eaves of the roof base, and the eaves attachment fitting (eave attachment fixture) 5 is installed. The position of the front portion 60 of the connecting piece 51 of the eaves mounting bracket 5 is the eaves side by the thickness of the eaves mounting bracket 5 (ml in FIG. 19) from the projected dimension of the slate roof tile 2 from the eaves (tl in FIG. 19). It will be the position that came out.
The eaves mounting bracket 5 is mounted by inserting a fastening element 115 such as a wood screw or a nail into the mounting hole 59 of the lower plate portion 52 and engaging the fastening element 115 with the roof base.
The eaves mounting bracket 5 is mounted with a small interval so that there is no gap in the eaves when viewed from the front 60 side.

  As shown in FIG. 17, in a state where the eaves mounting bracket 5 is attached to the eaves, the roof member holding recess 64 constituted by the lower plate portion 52, the first front rising portion 53, and the upper plate portion 55 is formed. Open to the side.

And as the next process, the slate roof tile 2-1 of the row | line | column of the eaves side 1st step | line is installed. The side of the eaves side is held by the slate tile being fitted into the roof member holding recess 64 of the eaves tip mounting bracket 5 described above. (Fig. 18)
Further, since the slate tile covers the entire upper part of the lower plate portion 52 of the eaves attachment bracket 5, the attachment hole 59 of the eaves attachment bracket 5 is covered with the slate tile 2-1 in the first row of the eaves side. Therefore, rainwater does not enter the mounting hole 59 of the eaves mounting bracket 5.

  Further, as described above, since the four attachment holes 12 are provided in the slate roof tile 2, a nail 116 or the like is inserted into the attachment hole and engaged with the roof base, and an intermediate portion of the slate roof tile 2-1. To fix. As a result, as shown in FIG. 19, the slate roof tiles 2-1 in the first row of eaves side are held by the eaves tip mounting bracket 5 and the middle portion is fixed by a nail 116 or the like, which is stable as a whole. To do.

Subsequently, the second row of slate roof tiles 2-2 is installed from the eaves side.
The installation method of the second row of slate tiles 2-2 is the same as the known roof construction, and a part of the slate tile 2-1 of the first row of slate tiles 2-1 laid on the eaves side first. Then, a part of the eaves side of the slate roof tile 2-2 in the second row is overlaid (FIG. 20).
Here, the size of the overlap between the slate roof tile 2-1 in the first row and the slate roof tile 2-2 in the second row depends on the rule of thumb, but at least the slate roof 2- in the first row. The first mounting hole 12 is overlapped with the second row of slate roof tiles 2-2. As described above, the mounting holes 12 of the slate roof tiles 2 are arranged in a line near the center of the slate roof tile 2 in the short direction, so that the slate roof tiles 2-1 in the first row and the second row of rows are aligned. The overlap (OW) of the slate roof tile 2-2 exceeds 50 percent of the length of the slate roof tile 2 in the short direction.

When the installation of the slate roof tiles 2-2 in the second row is finished, the nails 117 are inserted through the four mounting holes 12 of the slate roof tiles 2-2 in the second row to cover the nails 117. In this embodiment, the intermediate mounting bracket (mounting tool) 6 is attached in parallel with this step.
As a recommended procedure, as shown in FIGS. 21 and 22, the intermediate plate member 71 is detached from the assembled intermediate mounting member 6 and only the fixing member constituting member 70 is attached.

More specifically, only the fixing member constituting member 70 of the intermediate mounting bracket 6 is placed on the slate roof tiles 2-2 in the second row arranged in advance.
Here, the fixing portion constituting member 70 of the intermediate mounting bracket 6 has a lower plate member 72 and an upper plate member 73 and both are connected by a rising portion 75. It will be placed on the slate roof tile 2-2 in the second row. And, two holes in a total of four holes 100a, 100b, 101a, 101b in two rows and two columns provided in the lower plate member 72 of the fixed portion constituting member 70 are two holes in the front side row (the rising portion 75 side). 100a and 100b, and the fixing member 70 is attached using one of the holes. That is, any one of the holes 12a, 12b, 12c, 12d of the slate roof tile 2-2 in the second row and the holes 100a, 100b in the front row of the fixing member 70 are visually matched. Then, a screw is inserted into both of them, and the fixing member constituting member 70 is fixed. Here, the slate roof tiles 2-2 in the second row are in an exposed state, and the slate roof holes 12a, 12b, 12c, and 12d are directly visible, so the slate roof holes 12a , 12b, 12c, 12d and the holes 100a, 100b of the fixing member constituting member 70 can be easily matched.

Further, the upper plate member 73 exists on the lower plate member 72, but since the holes 102a and 102b are provided at positions corresponding to the upper portions of the holes 100a and 100b of the lower plate member 72, the holes 102a and 102b are provided. Screws can be inserted through the lower plate member 72 through 100a and 100b. Furthermore, since the holes 102a and 102b of the upper plate member 73 are larger than 100a and 100b of the lower plate member 72, the driver can easily rotate.
In a state in which the fixing portion constituting member 70 is fixed, the first concave portion 105 constituted by the lower plate member 72, the rising portion 75, and the upper plate member 73 opens toward the roof ridge side.
In addition, the slate tile holes 12a, 12b, 12c, and 12d in the second row, which are not used for fixing the fixing member 70, are inserted into the roof base by screws and nails. Is done.

When the fixing of the slate roof tiles 2-2 in the second row is completed as shown in FIG. 23, the slate roof tiles 2-3 in the third row are then attached as shown in FIG. The slate roof tiles 2-3 in the third row are inserted into the first concave portion 105 of the intermediate mounting bracket 6 at the front end portion of the eaves side. As described above, since the first recess 105 opens toward the roof ridge side, it is easy to insert the slate tile 2-3 in the third row.
As shown in FIGS. 24 and 25, the side of the eaves side of the slate roof tile 2-3 in the third row enters deeply into the first recess 105. Here, since the holes 100a and 100b of the lower plate member 72 through which the screws are inserted in the previous operation are in the first recess 105, the side of the eaves side of the slate roof tile 2-3 in the third row is arranged. By inserting the first concave portion 105, the third row of slate roof tiles 2-3 covers the lower plate member 72 100 a and 100 b. More specifically, portions other than the upper slate roof mounting holes overlap the upper portions of the lower plate member 72 at 100a and 100b. Therefore, rainwater does not enter the holes 100a and 100b of the lower plate member 72.

Further, in this state, the lower row of the upper plate member 73 of the intermediate mounting bracket 6 has the third row of slate roof tiles 2-3 in the entire region. Then, as the next step, as shown in FIGS. 26 and 27, one of the mounting holes 80a and 80b provided near the rear end of the upper plate member 73 of the intermediate mounting bracket 6 and the slate in the third row. One of the holes 12a, 12b, 12c, and 12d of the roof tile 2-3 is matched, and a nail 118 (a nail or a screw) is inserted through both of them to fix the intermediate mounting bracket 6.
Here, the hole used for mounting the intermediate mounting bracket 6 is the hole (slate roof tile 2-2 that was selected when the screw 117 or the like was previously inserted between the second stage row of slate roof tiles 2-2. It is desirable to select a hole (any one of 12a, 12b, 12c, and 12d of the slate roof tile 2-3) at a position shifted in the column direction with respect to any one of 12a, 12b, 12c, and 12d.
More specifically, as shown in FIG. 28, among the four mounting holes provided in the lower plate member 72, the two front mounting holes 100a and 100b and the rear end side hole are arranged. Of the 80a and 80b, if the lower plate member 72 is fixed first using the mounting hole 100a, the hole 80b is selected as the hole in the rear end row. On the other hand, if the lower plate member 72 is fixed first using the mounting hole 100b, the hole 80a is selected as the hole in the rear end row.
In other words, the hole is selected so that the straight line connecting the hole through which the screw 117 or the like is inserted on the front side and the hole through which the screw or the like 118 is inserted on the rear side is a line inclined with respect to the inclination direction of the roof.
In the present embodiment, since the intermediate mounting bracket 6 is fixed with the screws provided in such a shifted position, the mounting strength of the intermediate mounting bracket 6 is strong.

The operation of matching any one of the mounting holes 80a and 80b of the intermediate mounting bracket 6 and any of the holes 12a, 12b, 12c, and 12d of the slate roof tile 2-3 in the third row is as follows. Since the upper plate member 73 is placed in an exposed state on the slate roof tiles 2-3 in the third row, it is easy because the holes can be directly observed.
Further, the total length of the upper plate member 73 is longer than the total length of the lower plate member 72, and the lower plate member 72 does not exist below the mounting holes 80a, 80b provided near the rear end of the lower plate member 72. Etc. 118 simply passes through any one of the mounting holes 80a, 80b of the upper plate member 73 and the holes 12a, 12b, 12c, 12d of the slate roof tile 2-3, and the work can be performed in a visible state. Because it can, workability is good.

Subsequently, the slate roof tiles 2-4 in the fourth row are laid. The laying operation of the fourth row of slate roof tiles is substantially the same as the above-described laying operation of the second row of slate roof tiles 2-2. A part on the eaves side of the slate roof tile 2-4 in the fourth row is overlapped with a part on the ridge side 2-3 (FIG. 29). The size of the overlap between the slate roof tiles 2-3 in the third row and the slate roof tiles 2-4 in the fourth row depends on empirical rules, but is at least that of the slate roof 2-3 in the third row. The mounting holes 12 (any one of 12a, 12b, 12c, and 12d) are stacked so as to cover the slate roof tiles 2-4 in the fourth row.
Therefore, the slate roof tiles 2-4 in the fourth row are covered on the mounting holes 80a and 80b of the intermediate mounting bracket 6 and the fastening elements such as the nail 118. More specifically, parts other than the attachment holes 12 (12a, 12b, 12c, 12d) of the upper slate roof tile 2-4 overlap the upper portions of the attachment holes 80a, 80b of the upper plate member 73. Therefore, rainwater does not enter the mounting holes 80a and 80b of the upper plate member 73.

  Then, as shown in FIG. 30, when the installation of the slate roof tiles 2-4 in the fourth row is finished, the slate roof tiles 2-4 in the fourth row are finished as in the laying work of the second row. The nails 119 are inserted into the four mounting holes 12 to engage the nails 119 with the roof base, and the intermediate mounting bracket 6 is attached in parallel with this process. The work of attaching the intermediate mounting bracket 6 is the same as the work of the second row. Then, as shown in FIG. 31, the slate roof tile 2-5 is attached by the same method as the slate roof tile 2-3 described above.

In this way, the fifth and sixth stages are sequentially constructed, and the slate roof tile 2 is attached until reaching the building. Then, as shown in FIG. 32, the laying of the slate tile 2 is completed on the roof base, and the foundation roof structure 3 is completed.
As a result, the eaves mounting bracket 5 is fixed to the most eaves side of the roof, and only the fixed portion constituting member 70 of the intermediate mounting bracket 6 is mounted on every other slate tile 2.
As described above, in the present embodiment, the four attachment holes 12 of the slate roof tile 2 are used for the attachment of the intermediate attachment 6 (fixed portion constituting member 70). Therefore, it is not necessary to perform processing such as providing a new mounting hole in the slate roof tile 2, and the strength is not reduced by the hole provided in the new slate roof tile 2. In addition, since the slate tile 2 can be attached without processing, the attachment work is easy.

Subsequently, the solar cell module 10 is installed on the basic roof structure 3.
In the present embodiment, the solar cell module 10 is wired when the solar cell module 10 is laid.

The solar cell modules 10 are arranged on the foundation roof structure 3 in a row and in a plurality of stages and are placed with a planar spread, but the wiring is simple, and the solar cell modules 10 adjacent on the same row are arranged. Just connect the cable.
In the present embodiment, as shown in FIG. 33, in the adjacent solar cell modules 10, 10, the first connector 20 of one solar cell module 10 and the second connector 22 of the other adjacent solar cell module 10 are When connected, two adjacent solar cell modules 10 and 10 can be electrically connected in parallel as shown in FIG. That is, by connecting the white first connector 20 attached to the white first cable 16 and the black second connector 22 attached to the black first cable 18, the adjacent solar cell modules 10, Ten parallel connections are possible. Therefore, the solar cell module 10 of this embodiment connects all the solar cell modules 10 included in the module stage 36 sequentially in parallel by connecting the left and right adjacent solar cell modules 10 and 10 using the cables 16 and 18. Can be connected to.

  Hereinafter, the process of attaching the solar cell module 10 onto the basic roof structure 3 and the cable wiring work performed in parallel therewith will be described.

The solar cell module 10 is laid in order from the eaves side row.
Since the eaves mounting bracket 5 is attached to the eaves by the operation of constructing the basic roof structure 3 described above, the solar cell modules 10-1 in the first row are inserted into the module holding recesses 65 of the eaves mounting bracket 5. Engage the eaves side (the side where the cable does not protrude).
That is, as shown in FIG. 35, in the eaves-end fitting 5, a module holding recess 65 is constituted by the support base 57, the second front rising portion 58, and the cover plate constituting portion 61, and the module holding recess 65 is a building. It opens toward the ridge side. Therefore, the eaves side of the solar cell module 10-1 is slid into the module holding recess 65 from the ridge side.

On the other hand, as shown in FIG. 36, the ridge side of the solar cell module 10-1 (the side from which the cable protrudes) is the central area of the fixing member constituting member 70 attached to the second-stage slate roof tile 2-2. Place on the front side of B.
Then, the intermediate plate member 71 and the pressing plate member 74 are attached to the fixed portion constituting member 70 while the ridge side of the solar cell module 10-1 is placed on the front end portion of the central area B. In practice, the intermediate plate member 71 and the pressing plate member 74 are integrated in advance, and in this state, the intermediate plate member 71 and the pressing plate member 74 are attached to the fixed portion constituting member 70 (FIG. 37).

More practically, the screws 91 a and 91 b are engaged with the female screw holes 84 a and 84 b of the fixed portion constituting member 70 in a loosened state, and the first flat plate portion 85 of the intermediate plate member 71 is engaged with the fixed portion constituting member 70. The intermediate plate member 71 is slid to the eaves side while being pressed against the area B, and the heads of the screws 91a and 91b are passed through the long hole extension 90 provided on the wall surface of the first step portion 86, and the screws 91a, 91 b is led to the long hole 89.
Thereafter, the screws 91a and 91b are tightened. As a result, the front surface side of the solar cell module 10-1 is pressed on the back surface side of the intermediate plate member 71. In other words, the intermediate plate member 71 provided on the upper plate member 73 and the area A of the upper plate member 73 of the intermediate mounting bracket 6 by attaching the intermediate plate member 71 and the pressing plate member 74 to the fixed portion constituting member 70. As a result, the second recess 106 is formed, and the ridge side of the solar cell module 10-1 is engaged with the second recess 106.

In this state, as shown in FIG. 38, the solar cell module 10-1 is engaged with the module holding recess 65 of the eaves end mounting bracket 5 on the eave side and the second recess 106 of the intermediate mounting bracket 6 on the ridge side. Since the two sides are engaged with each other, both sides facing each other are held and cannot be detached from the foundation roof structure 3.
Moreover, since the cover 66 and the protective member 67 are provided in the module holding recess 65 that engages with the eaves side, the eaves side of the solar cell module 10-1 is not damaged and does not rattle.
Similarly, since the foamed elastic body 108 and the sealing member 109 are similarly provided in the second recess 106 of the intermediate mounting bracket 6, the ridge side of the solar cell module 10-1 is not damaged and does not rattle. .

When the solar cell modules 10-1 in the first row are attached in this manner, the cables are subsequently wired between the adjacent solar cell modules.
That is, the first cable 16 and the second cable 18 of the adjacent solar cell modules 10-1 and 10-1 are connected.

  Here, in the solar cell module 10 of the present embodiment, the first cable 16 is formed shorter than the second cable 18 as described above. Therefore, in the solar cell module 10, the operator confirms the length of the cables 16, 18, so that the connectors 20, 22 attached to the cables 16, 18 are the first connectors 20, or the second connectors 22. It can be instantly determined.

Moreover, in this embodiment, since the cables 16 and 18 protrude from the long side 150 on the ridge side of the solar cell module 10, the connection work between the connectors 20 and 22 is performed on the outer upper side of the solar cell module 10. Can do. When the solar cell modules 10 in the upper row are installed, the cables 16 and 18 (including the connectors 20 and 22) wired in the wiring storage space 41 of the solar cell modules 10 in the upper row are accommodated. Become.
Here, in this embodiment, since the hook portion 77 is provided in the intermediate mounting bracket 6, the cable processing is facilitated by engaging the cable that has been wired with the hook portion 77.

That is, as shown in FIG. 39, at the stage where the first-stage solar cell module 10-1 has been laid, the upper stage portion is still in a state where the slate roof tile 2 is exposed, The hook portion 77 provided on the plate member 73 is exposed to the outside.
Therefore, the connected cables as shown in FIGS. 40 and 41 can be easily engaged with the hook portion 77. The cable is positioned by being engaged with the hook portion 77, and the cable is prevented from going further to the ridge side than the hook portion 77.

Subsequently, the second-stage solar cell module 10-2 is laid.
As shown in FIGS. 42 and 43, the second-stage solar cell module 10-2 is installed between the intermediate mounting brackets 6. That is, the intermediate mounting bracket 6 is mounted on every two slate roof tiles 2 as described above.
The second-stage solar cell module 10-2 includes an intermediate mounting bracket 6 that holds the ridge side of the first-stage solar cell module 10-1 (hereinafter referred to as a lower-side intermediate mounting bracket 6) and an upper side thereof. Are fixed to an intermediate mounting bracket 6 (hereinafter referred to as an upper-side intermediate mounting bracket 6).
Specifically, in the second-stage solar cell module 10-2, the side on the eave side is engaged with the third recess 107 (module mounting portion) of the lower-side intermediate mounting bracket 6.
That is, the lower intermediate mounting bracket 6 has a third recess 107 constituted by a part of the intermediate plate member 71 and the pressing plate member 74. The third recess 107 opens in the same direction as the first recess 105 and opens toward the ridge side.
Therefore, the eaves side of the solar cell module 10-2 can be slid from the ridge side to the third recess 107 of the lower intermediate mounting bracket 6, and by this operation, the eaves side of the solar cell module 10-2 is moved to the lower middle. It can be engaged with the third recess 107 of the mounting bracket 6.

  The third recess 107 of the lower-side intermediate mounting bracket 6 is in the central area B of the upper plate member 73 and is a high position portion. Therefore, the eaves side of the second stage solar cell module 10-2 overlaps the ridge side of the first stage solar cell module 10-1.

On the other hand, the ridge side of the solar cell module 10-2 (the side from which the cable protrudes) is the upper side attached to the fourth-stage slate roof tile 2-4, like the first-stage solar cell module 10-1. The fixed portion constituting member 70 is placed on the front end side of the central area B (FIG. 42).
Then, the intermediate plate member 71 and the pressing plate member 74 are attached to the fixed portion constituting member 70 while the ridge side of the solar cell module 10-2 is placed on the central area B, and the back side of the intermediate plate member 71 is attached. Hold with. As a result, the second recessed portion 106 is formed by the front plate side area A and the central area B of the upper plate member 73 of the upper intermediate fitting 6 and the intermediate plate member 71 provided on the upper plate member 73. The side of the ridge side of the solar cell module 10-2 is engaged with the recess 106, and the opposite sides of the solar cell module 10-2 are held, so that the solar cell module 10-2 cannot be detached from the foundation roof structure.

Further, the third recess 107 that engages the eaves side of the solar cell module 10-2 is provided with a seal member 110 (not shown in FIGS. 42 and 43 for convenience of drawing). The eaves side of the module 10-2 is not damaged and does not rattle.
Similarly, since the foamed elastic body 108 and the sealing member 109 are similarly provided in the second concave portion 106 of the upper intermediate mounting bracket 6, the ridge side of the solar cell module 10-2 is not damaged and is loose. Nor.

As shown in FIG. 44, the cables 16 and 18 of the first-stage solar cell modules 10-1 and 10-1 previously wired are provided on the upper plate member 73 of the lower-side intermediate mounting bracket 6. Since the hook portion 77 is engaged, the cable is stored in the wiring storage space 41 on the back surface side of the solar cell module.
That is, as described above, the heat insulation reinforcing material 23 is provided on the back surface side of the solar cell module 10, but the heat insulation reinforcing material 23 is missing and a predetermined gap is provided in the vicinity of the eave side. . In this embodiment, since the cable is engaged with the hook part 77 protruding from the foundation roof structure part side, the cable does not enter the ridge side excessively. Therefore, even if the second-stage solar cell module 10-2 is installed, the heat insulation reinforcing material 23 of the second-stage solar cell module 10-2 steps on the cable of the first-stage solar cell module 10-1. There is nothing.

  When all the second-stage solar cell modules 10-2 have been installed in this way, the cables are wired in the same manner as described above, and the cables are engaged with the hook portions 77. Further, a third-stage solar cell module 10-3 is installed. Thus, the solar cell modules 10 are sequentially installed, and when the installation of the desired number of stages is completed, the rain closing plate 11 is installed on the ridge side of the uppermost solar cell module 10 to complete the construction (FIG. 45).

When the roof structure 1 of this embodiment is exposed to rain, most of the rainwater flows over the solar cell module 10 to the eaves and falls from the eaves.
However, although some rainwater goes under the solar cell module 10, since the slate roof tile 2 is laid under the solar cell module 10, rainwater does not enter into the building. In addition, the slate tile 2 on the upper side overlaps the mounting holes of the intermediate mounting bracket 6 so that rainwater does not enter the mounting holes.

Referring to FIG. 29, the roof member (slate tile 2-3) into which the edge on the eaves side is inserted into the first recess 105 of the intermediate mounting bracket 6 is defined as a “specific roof member”, and the lower plate of the intermediate mounting bracket 6 The roof member (slate tile 2-2) that is located below the member 72 and overlaps with the “specific roof member” is defined as the “lower roof member”, and the eaves-side freedom on the “specific roof member” The roof member (slate tile 2-4) which has an end and overlaps with the “specific roof member” will be described as the “upper roof member”.
The intermediate mounting bracket 6 is attached to the end portion of the “specific roof member”, and the lower plate member 72 is disposed between the “specific roof member” and the “lower roof member”. Then, screws or the like 117 (fastening elements) are inserted into the holes 100 (either the holes 100a or 100b) of the lower plate member 72, and the screws or the like 117 (fastening elements) are inserted into the mounting holes 12 of the “lower roof member”. As a result, the lower plate member 72 of the intermediate mounting bracket 6 is fixed to the roof.
As described above, the roof members (slate tiles 2) are arranged in a row and a plurality of stages in a state where a part of the roof members (slate tiles 2) overlap with the adjacent roof members (slate tiles 2) as if they were fish scales. A “specific roof member” is placed on a “lower roof member” which is placed with a flat spread (see FIG. 32) and screws 117 (fastening elements) are inserted therethrough. Therefore, the “specific roof member” is covered with the mounting hole 12 of the “lower roof member”, and rainwater does not enter the mounting hole 12.
Further, the upper plate member 73 is overlaid on the “specific roof member”, and a screw or the like 118 (fastening element) is inserted into the mounting hole 80 (one of the mounting holes 80a, 80b) of the upper plate member 73 to “specify” The screw or the like 118 (fastening element) is inserted into the mounting hole 12 of the roof member of the “roof member”, and the upper plate member 73 of the intermediate mounting bracket 6 is fixed to the foundation roof structure by the screw or the like 118 (fastening element). .
Further, since the “upper roof member” is placed on the “specific roof member” through which the screws 118 or the like are inserted, the “upper roof member” covers the mounting hole of the “specific roof member”. Rainwater will not enter the mounting holes.

The same applies to the mounting hole 59 of the eaves mounting bracket 5, and the first-stage slate roof tile 2-1 overlaps, and rainwater does not enter the mounting hole 59 (FIG. 19).
Therefore, the rainwater that has entered under the solar cell module 10 flows on the slate roof tile 2 and reaches the eaves. Here, since the fixing pieces 50 are attached to the eaves-end fitting 5 with a considerable interval, there is a large gap between the fixing pieces 50. Therefore, rainwater passes through this gap and falls under the eaves (FIG. 47).
Therefore, rainwater does not accumulate on the roof.

When attention is paid to the overlapping state of the slate roof tiles 2 in this embodiment, it can be said that the position of the terminal box 14 on the back surface side of the solar cell module 10 is also ideal.
That is, as described above, since the overlap of the slate roof tiles 2 at each stage exceeds 50% of the length of the slate roof tile 2 in the short direction, as shown in FIG. There is a portion X1 where the slate roof tiles 2 overlap and a portion X2 where the three slate roof tiles overlap.
More specifically, each of the slate roof tiles 2 has the eaves side end portion 128 exposed, but the eave side end portion 128 is always in the X2 position (for example, the eave side of the slate roof tile 2-3). The tip portion 128 is at the position X2a). On the other hand, the position ahead (eave side) of the eaves side front end portion 128 of each slate roof tile 2 is X1.
Therefore, when considering the height protruding from the roof base to the top side, the protruding amount of the portion (X2) where the three slate tiles 2 overlap is large, and the portion (X1) where the two slate tiles 2 overlap. The protruding amount of is small. In other words, the surface of the foundation roof structure 3 has irregularities, the eaves side front end portion 128 of each slate tile 2 protrudes the most, and the position ahead is the most concave.

On the other hand, the solar cell module 10 stacked on top has a flat plate shape. Moreover, the length of the short side direction of the solar cell module 10 is longer than that of the slate roof tile 2, and the solar cell module 10 is exposed to the exposed portions of the two slate roof tiles 2 (slate roof tiles 2-3 and 2-4). It is arranged across.
Therefore, the gap between the solar cell module 10 and the surface of the slate roof tile 2 varies depending on the position, and the portion (X1) where the two slate roof tiles 2 overlap has a large gap, and the three slate roof tiles 2 overlap. The gap of the portion (X2) that is present is small.

  Here, in the present embodiment, the terminal box 14 is fixed to the back surface side of the solar cell module 10 using an adhesive or the like, and its position is substantially the center of the long side of the solar cell module 10, and the upper side. It is attached at a position close to it (FIG. 5).

The upper side of the solar cell module 10 is held by an intermediate mounting bracket 6 attached to the protruding end portion of the slate roof tile 2-4. The solar cell module 10 has three upper side positions. This is the portion (X2c) where the slate roof tiles overlap. Therefore, the upper side of the solar cell module 10 is a position having the smallest gap with the surface of the slate roof tile.
Further, since the lower side of the solar cell module 10 is also held by the intermediate mounting bracket 6, the solar cell module 10 also has a portion (X2a) where three slate roof tiles overlap at the lower side position. ). Therefore, the lower side of the solar cell module 10 is a position having the smallest gap with the surface of the slate roof tile.
Furthermore, in this embodiment, since the solar cell module 10 is arranged straddling the exposed part of the two slate roof tiles 2-3 and 2-4, the slate roof tile 2 is also located immediately below the solar cell module 10. -4 has a tip. Accordingly, the central portion in the short direction of the solar cell module is also the portion (X2b) where the three slate roof tiles overlap. Therefore, the central portion of the solar cell module 10 is also the position where the gap with the surface of the slate roof tile is the smallest.

Conversely, the position excluding the vicinity of the upper and lower sides and the vicinity of the center is a portion (X1) where two slate roof tiles overlap, and is between the back side of the solar cell module 10 and the surface of the slate roof tile. The gap is large.
In the present embodiment, the terminal box 14 is located in an area where the gap is large.
That is, the terminal box 14 of the solar cell module is substantially at the center of the long side of the solar cell panel 13 as shown in FIG. 5, closer to the region on the upper side, and slightly inside the upper side. Installed in position.

This position is a portion (X1) where the two slate roof tiles overlap, and is a region where the gap between the back surface side of the solar cell module 10 and the surface of the slate roof tile is large.
Therefore, according to this embodiment, the height of the surface of the solar cell module 10 can be close to the height of the surface of the slate roof tile. There is a sense of unity between the solar cell module 10 and the underlying slate roof.
Therefore, the roof structure of this embodiment has a beautiful appearance.
In other words, the solar cell module 10 employed in the present embodiment has a thin thickness, and when it is placed on the roof, it is easy to produce a sense of unity with other parts of the roof and is beautiful.

Next, a procedure for maintaining the roof structure 1 of the present embodiment will be described.
When one of the solar cell modules 10 fails for some reason, the solar cell module 10 needs to be replaced. However, in the roof structure 1 of the present embodiment, the solar cell module 10 at an arbitrary position can be taken out without difficulty. it can.
For example, when the first-stage solar cell module 10 fails, the connection piece 51 of the eaves mounting bracket 5 is removed as shown in FIG. As described above, the connecting piece 51 is attached to the fixed piece 50 by the screws 62 and 63. Therefore, when the screws 62 and 63 are removed, the fixed piece 50 remains on the foundation roof structure 3 as shown in FIG. Only the connecting piece 51 comes off.
When the connection piece 51 is detached, the upper part of the module holding recess 65 (see FIG. 9 and the like) is removed, and the solar cell module can be extracted.

Further, when the solar cell module 10 in the second and subsequent stages fails, the pressing plate member 74 of the intermediate mounting bracket 6 is removed as shown in FIGS. As described above, the holding plate member 74 is attached to the intermediate plate member 71 by the screws 97a and 97b. Therefore, when the screws 97a and 97b are removed, the intermediate plate member 71 is mounted on the foundation roof structure 3 as shown in FIG. And only the presser plate member 74 is removed.
When the pressing plate member 74 is removed, the upper portion of the third recess 107 is removed, and the solar cell module 10 can be extracted upward as shown in FIG.

As described above, the intermediate mounting bracket 6 employed in the present embodiment is designed for the purpose of mounting on the roof when the foundation roof structure 3 is constructed, but it can also be mounted on an existing roof. Designed.
That is, in the intermediate mounting bracket 6 employed in the present embodiment, as described above, the lower plate member 72 is provided with holes 100 and 101 in two rows and two columns (see FIGS. 11, 12, and 13). As described above, the two holes 100a, 100b in the front row (the rising portion 75 side) out of the total four holes 100a, 100b, 101a, 101b in 2 rows and 2 columns, and the upper plate The intermediate mounting bracket 6 is mounted using mounting holes 80a and 80b provided near the rear end of the member 73 (a position far from the rising portion 75 side).

  On the other hand, when attaching the intermediate mounting bracket 6 to the existing roof, the mounting holes 80a and 80b in the vicinity of the rear end are not used, and a total of four in two rows and two columns provided in the lower plate member 72. Of the holes 100a, 100b, 101a, 101b, two holes 101a, 101b in the rear side row are used.

Hereinafter, a method for attaching the intermediate mounting bracket 6 to the existing roof will be described.
The existing roof, like the slate tiles 2 etc., is partly overlapped with the adjacent roof member, and the remaining part is exposed and arranged in a row and a plurality of steps on the roof base with a planar spread It is placed.
When attaching the intermediate mounting bracket 6 to such a completed roof, the lower plate member 72 of the intermediate mounting bracket 6 is inserted between the overlapping portions of the slate tile 2 as shown in FIG.
As a result, as shown in FIG. 51, the lower plate member 72 of the intermediate mounting bracket 6 slides under the specific slate roof tile 2 and cannot be seen from the outside. On the other hand, the upper half of the upper plate member 73 is exposed on the specific slate roof tile 2, and the latter half of the upper plate member 73 is also sunk under the roof tile overlapping the specific slate roof tile 2.
Accordingly, of the six holes 102a, 102b, 103a, 103b, 80a, 80b provided in the upper plate member 73, the mounting holes 80a, 80b near the rear end are hidden under the slate roof tile, but are provided in the front half. The two rows and two columns 102a, 102b, 103a, and 103b are exposed to the outside.

When attaching the intermediate mounting bracket 6 to the existing roof, the rear holes 103a and 103b are used among the two rows and two columns 102a, 102b, 103a and 103b exposed to the outside. That is, a fastening member such as a screw nail or a nail is directly inserted into the holes 103a and 103b. Of course, you may provide a pilot hole with a drill as needed.
When a screw nail, a nail, or the like is driven into the holes 103a, 103b, the tip of the nail or the like passes through the slate roof tile 2 and reaches the lower plate member 72 of the intermediate mounting bracket 6.
Here, in the intermediate mounting bracket 6 employed in the present embodiment, holes 101a and 101b are provided in the lower plate member 72 immediately below the holes 103a and 103b provided in the upper plate member 73 (see FIG. 13). . For this reason, when a nail or the like is driven from the upper plate member 73 side, the leading end of the nail or the like enters the holes 101a and 101b of the lower plate member 72, and further falls downward to engage with the roof base. Therefore, the intermediate mounting bracket 6 is firmly attached.

In the embodiment described above, the intermediate mounting bracket 6 is exemplified such that the length of the upper plate member 73 is longer than the length of the lower plate member 72. However, as shown in FIG. There may be. However, when such a configuration is adopted, it is necessary to provide a hole 121 in the lower plate member 72 directly below the mounting holes 80a and 80b in the vicinity of the rear end of the upper plate member 73.
Further, the lower plate member 72 may be longer as shown in FIG. When such a configuration is adopted, it is necessary to provide a hole 121 near the rear end of the lower plate member 72.

In embodiment described above, the magnitude | size of the solar cell module 10 was taken as the magnitude | size arrange | positioned ranging over the exposed part of the two slate roof tiles 2. FIG. However, the size of the solar cell module 10 is arbitrary, may be the same size as the slate roof tile 2, and is a size arranged across the exposed portions of the three slate roof tiles 2. Also good.
However, since the basic configuration of this embodiment is to attach the solar cell module 10 to the intermediate mounting bracket 6 attached to the eaves-side protrusion of the slate roof tile 2, the length of the solar cell module 10 in the short direction is plural. The length of the exposed portion of the slate roof tile 2 is added to the length of the overlap of the solar cell modules 10.

Moreover, the solar cell module 10 of above-mentioned embodiment is provided with the limitation groove | channel 21 which crosses each photovoltaic cell 17 as a specific structure (refer FIG. 3). A region (B region) above the limiting groove 21 is not connected to the terminal box 14.
This configuration is a configuration recommended for making the solar cell module 10 last longer. In other words, the above-described B region is a portion that is covered with the solar cell module 10 on the ridge side and is not shaded, and does not contribute to power generation. Therefore, there is no inconvenience even if the solar cell module 10 is provided with the limiting groove 21 and the region (B region) above the limiting groove 21 is not connected to the terminal box 14.

On the other hand, as shown in FIG. 1 and the like, this portion is a gap portion between the solar cell modules 10 and is a portion that may cause an unexpected failure due to the invasion of insects, spiders, birds, or the like.
That is, in this embodiment, each solar cell module 10 is attached via the intermediate mounting bracket 6. Since the intermediate mounting bracket 6 has a certain thickness, there is inevitably a gap between the eaves-side free end of each solar cell module 10 and the solar cell module 10 therebelow, so that insects and the like are present. invade. For example, there is a concern that bees may invade and form a nest, and ants may invade and form a nest.
Here, some of the secretions secreted by insects, spiders, etc. may cause unexpected harm over the years. For example, formic acid secreted by ants is a strong acid, and by touching this formic acid over a long period of time, a part of the solar cell module 10 may be corroded.

In addition, since the region B is a portion that is covered with the solar cell module 10 and is shaded, the state cannot be seen from the outside. Therefore, for example, a mouse may enter from the gap between the raining plates 11 and bite the solar cell module 10.
For this reason, the region (B region) above the limiting groove 21 has a fear of causing an unexpected short circuit, disconnection, or electric leakage. In addition, since the region is not visible from the outside, it is difficult to find the cause of the failure when a failure occurs, and there is a concern that all the solar cell modules 10 will be replaced after all.

Therefore, in the present embodiment, the portion covered with the solar cell module 10 on the ridge side is electrically separated by the limiting groove 21 to eliminate the concern about the accident.
Thus, although the structure which the limited groove | channel 21 which crosses each photovoltaic cell 17 provides is a recommended structure, it is not essential for this invention and adoption is arbitrary.

  In the embodiment described above, the pressing plate member 74 of the intermediate mounting bracket 6 employs a member having an L-shaped cross section, but the shape of the pressing plate member is not limited to this. For example, as shown in FIG. 53, a pressing plate member 114 having a “U” cross section may be used. The shape of the pressing plate member may be changed as appropriate.

  Moreover, in embodiment described above, although the heat insulation reinforcing material 23 which has the groove-shaped part 46 was attached to the solar cell module 10, the shape and number of heat insulation reinforcing materials are not restricted to this. For example, as shown in FIG. 54, a heat insulating reinforcement 135a having a "concave" shape in front view is attached to the central portion of the solar cell module 10, and 135b and 135c having substantially square shapes in front view are attached to both ends in the longitudinal direction. May be. You may change suitably the shape and number of a heat insulation reinforcing material.

  In the above-described roof structure of the present invention, the description has been given of the mode in which two hooks are provided on the upper plate member 73 of the intermediate mounting bracket 6 and the cable protruding from the solar cell module 10 is engaged to lock the cable. The method for locking the cable of the battery module 10 is not limited to this. For example, the cable may be locked by another member or method. Further, the number of hook portions 77 (members that engage the cable) is not limited to two. These may be one, or three or more. Furthermore, the position where the hook portion 77 (member that engages the cable) is provided is not limited to the upper plate member, and may be installed at an appropriate location such as the rising portion 75.

  For example, as shown in FIG. 55, the upper plate member 73 may be cut and raised, and a plate-like locking portion 123 protruding from the upper plate member 73 may be provided. And you may arrange | position a cable so that the latching | locking part 123 may be met. When arranged in this way, the cable is restrained to the eaves side by the contact surface of the locking portion 123 with the cable, so that it is possible to prevent the cable from moving to an unspecified location.

  Also, as shown in FIG. 56, the upper plate member 73 may be bent to form a groove-like locking portion 124 into which the cable can be fitted. When the cable is arranged in the locking portion 124, the cable is arranged along the groove, so that the cable can be held at a predetermined position, and the cable does not move to an unspecified position.

  Furthermore, as shown in FIG. 57, a hook-shaped locking portion 125 having a tip portion bent in a hook shape may be formed. The locking portion 125 is longer in the width direction (the direction of the arrow X in FIG. 57) than the two hooks described above.

  In addition, as shown in FIG. 58, an annular locking portion 126 may be provided so that the cable is inserted into the hole inside the locking portion 126. According to such a locking method, since the cable is firmly fixed to the intermediate mounting bracket 6, it is possible to more reliably prevent the cable from moving to a position outside the specified range.

  Further, as shown in FIG. 59, a plurality of plate-like portions protruding from the upper plate member 73 are provided by means such as cutting and raising the upper plate member 73, and the cut and raised plate-like portions are arranged to face each other. Thus, the locking portion 127 may be formed. And a cable may be arrange | positioned between plate-shaped parts and the position of a cable may be fixed.

  In addition, the latching | locking part for latching a cable is not restricted to what processes the intermediate attachment metal fitting 6. FIG. As shown in FIG. 60, the locking portion 129 may be separately prepared and attached to the intermediate mounting bracket 6 by appropriate means such as welding such as spot welding or a fastening element such as a screw.

Further, the above-described locking portions 123 to 127 and 129 are not provided only on the upper plate member 73. For example, as shown in FIG. 61, the groove-shaped locking part 130 may be arranged in the rising part 75.
In addition, although the method of locking the cable of the solar cell module 10 can be appropriately changed as described above, the direction toward the front end side area A as in the hook portion 77 described above (the direction that becomes the eave side when attached) It is desirable to use hooks bent to). According to such a locking method, when the solar cell module 10 is replaced by maintenance or the like, the cables 16 and 18 are detached from the hook portion 77 simply by pulling the solar cell module 10 to the eaves side, so that the replacement work can be easily performed. Can do.

Hereinafter, the cross-sectional structure of the solar battery cell 17 of the solar battery panel 13 employed in the above-described embodiment will be additionally described. FIG. 62 is an example of a conceptual diagram of a solar cell for simply explaining the layer configuration of the solar cell panel 13. As shown in FIG. 62, the solar cell panel 13 is formed by sequentially laminating a transparent conductive film 142, a semiconductor layer 143, and a back electrode film 144 on a glass substrate 141. The transparent conductive film 142 and the back electrode film 144 are stacked. A potential difference occurs between the two. That is, the transparent conductive film 142, the semiconductor layer 143, and the back electrode film 144 constitute a solar cell 140.
However, the voltage generated by one solar cell 140 is extremely low, and a single solar cell 140 alone does not reach a practical voltage. Therefore, a plurality of grooves 15 are provided in the thin film of the solar cell 140 to divide it into a large number of unit cells (solar cells 17), and the large number of solar cells 17 are electrically connected in series to increase to a practical voltage. Ingenuity has been made. Such a solar cell is called an integrated solar cell.

FIG. 63 is a conceptual diagram for conceptually explaining the layer configuration of the integrated solar cell configured in the solar cell panel 13 employed in the present embodiment.
The layer structure of the integrated solar cell 155 of the solar cell panel 13 is such that a transparent conductive film 142, a semiconductor layer 143, and a back-side electrode film 144 are sequentially laminated on a glass substrate 141, and grooves 156, 157, 158 is formed.

That is, the first groove 156 is formed in the transparent conductive film 142, and the transparent conductive film 142 is divided into a plurality of parts. In addition, a second groove (electrical connection groove) 157 is formed in the semiconductor layer 143, the semiconductor layer 143 is divided into a plurality of parts, and a part of the back-side electrode film 144 enters the second groove 157 to form the groove. It is in contact with the transparent conductive film 142 at the bottom.
Further, a third groove 158 is formed by cutting away the back-side electrode film 144 and the semiconductor layer 143 and reaching the surface of the transparent conductive film 142.

  Further, in the vicinity of the end portion of the integrated solar cell 155, three rows of electrode connection grooves 159 extending from the back surface side electrode film 144 and the semiconductor layer 143 to the transparent conductive film 142 are provided. Solder 160 is poured into the electrode connection groove 159, and a lead 161 disposed on the upper portion of the laminated body is connected. The lead 161 communicates with the transparent conductive film 142 via the solder 160. Although not shown, the back-side electrode film 144 is also in electrical communication with another lead 161 and solder 160.

  A separation groove 162 is formed outside the electrode connection groove 159. As shown in FIG. 63, the separation groove 162 is a groove formed by removing all of the transparent conductive film 142, the semiconductor layer 143, and the back-side electrode film 144.

  And the limiting groove 21 which crosses each photovoltaic cell 17 is provided. The limited groove 21 is also a groove formed by removing all of the transparent conductive film 142, the semiconductor layer 143, and the back-side electrode film 144 as shown in FIG.

Furthermore, the outermost part of the glass substrate 141 is a bare ground portion 165 from which the laminate is removed.
Further, the further back side of the back side electrode film 144 is covered with a coating film (not shown).

The integrated solar cell 155 configured in the solar cell panel 13 includes a first groove 156 provided in the transparent conductive film 142, a semiconductor layer 143 (specifically, having a p layer, an i layer, and an n layer) and a back surface. Each thin film is partitioned by a third groove 158 provided in the side electrode film 144, and an independent cell is formed. As described above, a part of the back-side electrode film 144 enters the second groove 157, and a part of the back-side electrode film 144 is in contact with the transparent conductive film 142, and one cell is an adjacent cell. And electrically connected in series.
That is, the current generated in the semiconductor layer (solar cell film) 143 flows from the transparent conductive film 142 side toward the back electrode film 144 side, but a part of the back electrode film 144 is transparent via the second groove 157. The current generated in the first cell is in contact with the conductive film 142 and flows in the transparent conductive film 142 of the adjacent cell. For this reason, the voltages are sequentially added.

In addition, since the limited groove 21 crossing each photovoltaic cell 17 is provided as described above, two large and small integrated solar cells 163 and 164 are configured. As described above, the limiting groove 21 is formed by removing the transparent conductive film 142, the semiconductor layer 143, and the back-side electrode film 144 together, so that the large and small integrated solar cells 163 and 164 are formed as follows. It is electrically insulated.
Only the integrated solar cell 163 in the area A (operating area) on the lower side of the drawing is connected to the terminal box 14. The integrated solar cell 164 in the B region (non-operating region) is not connected to the terminal box 14.
That is, the A region (operating region) 161 a of the lead 161 provided at the end is connected to the terminal box 14, and the lead 161 b in the B region (non-operating region) is not connected to the terminal box 14.

  The grooves are formed by laser scribing using a laser processing machine. Sand blasting or the like is employed for forming the bare ground portion 165.

It is preferable to use an integrated solar cell as described above or a so-called thin film solar cell as the solar cell module 10 of the present invention because the solar cell module 10 can be designed to be thin.
However, the solar cell used in the solar cell module 10 of the present invention is not limited to such a thin-film solar cell or an integrated solar cell. These may be replaced with arbitrary solar cells.
