Description

  The present invention relates to a roof structure formed by arranging solar cell modules side by side.

In recent years, solar cell modules have attracted attention as a new energy source due to increasing environmental awareness. This solar cell module has a structure including a solar cell panel which is a photoelectric conversion device capable of converting light energy into electric energy.
The solar cell panel includes a transparent electrode layer, a back electrode layer, and a photoelectric conversion element sandwiched between the two electrode layers. The photoelectric conversion layer including the photoelectric conversion element is provided with a glass plate, a back surface, and a back plate. It is sealed in a state sandwiched between backside sealing materials formed of a sheet or glass. Then, carriers generated by irradiating the photoelectric conversion layer with light can be collected in the electrode layer and taken out to an external circuit.

Conventionally, such a solar cell module is attached to the roof of a building directly or via a metal fitting, or attached to a pedestal installed on a flat ground.
For example, Patent Document 1 related to the application of the present applicant discloses a roof structure in which a solar cell module is mounted on a roof via a metal fitting that is integrally attached to a slate roof tile.

Here, the solar cell module includes a module with a frame attached to the outer peripheral portion and a frameless module without the frame. Since the frameless solar cell module is small and light, it has an advantage of being easy to mount and excellent in appearance.
More specifically, in a solar cell module with a frame, when it is mounted on a roof, the metal frame portion may appear more conspicuous than the peripheral portion. In this case, the metal portion impairs the sense of unity of the roof appearance, which is not preferable from the viewpoint of making the roof appearance beautiful.
On the other hand, in the frameless solar cell module, since there is no metal portion at the edge portion, a clean and beautiful appearance can be realized.

  Here, in order to further improve the appearance, the present inventors have considered that the solar cell panel of the frameless solar cell module is further thinned and mounted on the roof. However, if the solar cell panel is not formed with a frame and is formed thin, there is a problem that the strength of the solar cell module is weakened. That is, there is a possibility that the solar cell module may be damaged by a snow load or a blowing load due to a strong wind. And depending on the place where it was damaged, there is a possibility that the amount of power generation is reduced or the power generation is impossible.

That is, a wall-like portion 70 a that intersects the lower surface of the upper plate portion 62 substantially perpendicularly is formed in the lower rear portion of the upper massive portion 70. The wall-like portion 70 a is a portion having a substantially rectangular shape when viewed from the rear side, and the upper end portion is continuous with the lower surface of the upper plate portion 62 positioned rearward, and the lower end portion is continuous with the lower surface of the upper lump-like portion 70. ing.

  The long groove portion 71 is a portion having a substantially rectangular cross-sectional shape and extending along the longitudinal direction of the upper plate portion 62, and is a portion that is recessed from the periphery. The long groove portion 71 is in a state extending from one end portion to the other end portion in the longitudinal direction of the upper plate portion 62.

  In the present embodiment, the two long groove portions 71 are arranged in parallel with a gap in the short direction of the upper plate portion 62 (in the direction of the eaves building when being mounted on the roof). That is, the two long groove portions 71 are formed at positions separated from each other in the short direction of the upper plate portion 62.

The protrusion 66 formed on the upper plate 62 has the same shape as the protrusion 66 formed on the lower plate 60 described above, but the protruding direction is different. That is, the protrusion 66 of the upper plate portion 62 is a thin plate-like portion protruding rearward and lower.
Here, also on the lower surface of the upper plate portion 62, the two protrusions 66 are formed at positions separated from each other in the short direction of the upper plate portion 62. That is, the two ridge portions 66 are formed at positions separated from each other in the short direction of the upper plate portion 62.

  In the buffer member 17, the upper plate portion 62 and the lower plate portion 60 are opposed to each other with an interval in the vertical direction, and the upper lump portion 70 that is a part of the upper plate portion 62 and a part of the lower plate portion 60. Are also opposed to each other with a gap in the vertical direction. That is, the upper lump portion 70 and the lower lump portion 65 are located at the same position in the front-rear direction (eave building direction) of the buffer member 17, and both are located at the eave side end. The lower block 65 is located at a position away from the upper block 70 downward.

Of the two ridges 66 of the upper plate portion 62, the two ridges 66 of the lower plate portion 60 are located on the eaves side below the ridge portion 66 located on the eaves side. The protrusion 66 is located. Of the two ridges 66 of the upper plate part 62, the two ridges 66 of the lower plate part 60 are located on the ridge side below the ridge part 66 located on the ridge side. The protrusion 66 is located.
That is, the protrusion 66 formed on the upper plate 62 is located below the protrusion 66 formed on the lower plate 60. In other words, each of the protrusions 66 formed on the upper plate part 62 is in a state of being opposed to and separated from another protrusion 66 formed on the lower plate part 60 in the vertical direction.

In the present embodiment, the thickness of the upper plate portion 62 is thicker than the thickness of the lower plate portion 60. More specifically, when the cross-sectional area of the upper plate part 62 in the cross section orthogonal to the longitudinal direction of the buffer member 17 is compared with the cross-sectional area of the lower plate part 60 in the same cross section, the cross-sectional area of the upper plate part 62 Is not less than 1.3 times and not more than 2 times the cross-sectional area of the lower plate portion 60.
At this time, when the eaves side end portion (upper lump portion 70) of the upper plate portion 62 and the eave side end portion (lower lump portion 65) of the lower plate portion 60 are compared, the eave side end portion of the upper plate portion 62 is It is thicker than the eaves side end of the lower plate part 60. In addition, in other parts of the upper plate part 62 and other parts of the lower plate part 60, the other parts of the upper plate part 62 are thick.

  As shown in FIG. 8, the buffer member 17 is formed on the solar cell module 4 by positioning the ridge side of the solar cell module 4 in a space formed between the upper plate portion 62 and the lower plate portion 60. On the other hand, it is attached integrally. In other words, in the buffer member 17, the space formed between the upper plate portion 62 and the lower plate portion 60 is a space in which the eaves side portion is opened, and the upper lump portion 70 and the lower lump portion 65. A portion between the two functions as a portion that functions as an introduction port of the solar cell module 4. When the buffer member 17 is attached to the solar cell module 4 (the solar cell panel 10 and the long side reinforcing member 50), the ridge side portion of the solar cell module 4 is sandwiched between the upper plate portion 62 and the lower plate portion 60. Become.

More specifically, in the upper plate portion 62, the upper lump portion 70 and the lower portions of the two protrusions 66 are in contact with the upper surface of the solar cell module 4 (solar cell panel 10). . A gap is formed between the other part of the upper plate part 62 and the upper surface of the solar cell module 4.
Similarly, in the lower plate portion 60, the lower block 65 and the upper portions of the two protrusions 66 are in contact with the lower surface of the solar cell module 4 (solar cell panel 10 and long side reinforcing member 50). It has become. That is, a gap is also formed between the other part of the lower plate portion 60 and the lower surface of the solar cell module 4.

  And the eaves side part of the protrusion part 68 is in the state which contacted the ridge side end surface of the solar cell module 4 (long side reinforcement member 50) among the standing board parts 61. FIG. As a result, a drainage space 75 that is a space surrounded by the two protruding portions 68, the ridge side end surface of the long side reinforcing member 50, and the eaves side surface of the standing plate portion 61 is formed. The drainage space 75 is a groove-like space extending in the longitudinal direction of the buffer member 17, and is a space extending in a direction orthogonal to the eave building direction, that is, a direction parallel to the building ridge when installed.

Thus, by forming the drainage space 75 that is a space for drainage, the buffer member 17 of the present embodiment has a structure in which rainwater or the like is unlikely to collect between the solar cell panel 10 and the buffer member 17. .
In addition, a gap is formed between a portion of the eaves side surface of the upright plate portion 61 where the protruding portion 68 is not formed and the ridge side end surface of the solar cell module 4.

Here, as described above, the buffer member 17 is in a state of being integrally attached to the solar cell panel 10 by being brought closer to the eaves side from the ridge side of the solar cell panel 10. In other words, the buffer member 17 is integrally attached to the solar cell panel 10 by moving the solar cell panel 10 relatively close to the buffer member 17, that is, relatively moving toward the ridge side. It becomes.
That is, it can be said that the insertion direction when the solar cell panel 10 is attached is a direction from the eave side to the ridge side, and the removal direction is a direction from the ridge side to the eave side.

  And as above-mentioned, the protrusion part 66 is the state which the protrusion end inclined to the ridge side. That is, the solar cell panel 10 is inclined toward the front end side in the insertion direction. Thus, the buffer member 17 is easy to attach to the solar cell panel 10 and hardly come off.

  More specifically, when the buffer member 17 is attached to the solar cell panel 10, that is, when the solar cell panel 10 is inserted between the upper plate portion 62 and the lower plate portion 60 of the buffer member 17, the solar cell When the panel 10 is moved relative to the ridge side, each protrusion 66 is pushed to the ridge side by the solar cell panel 10. At this time, since each protrusion 66 is inclined toward the ridge, the protrusion 66 pressed by the solar cell panel 10 is shifted to a state where it is largely inclined as it is. That is, since the ridge 66 that has been inclined in advance is largely inclined as it is, a large force is not required to deform the ridge 66.

On the other hand, when removing the buffer member 17 from the solar cell panel 10, the solar cell panel 10 is moved relative to the eaves side. At this time, the ridge 66 is in a state of being greatly inclined and tends to return to its original shape due to elasticity, so the upper ridge 66 presses the solar cell panel 10 downward, The protrusion 66 presses the solar cell panel 10 upward. In other words, the solar cell panel 10 is tightened by the upper and lower ridge portions 66. For this reason, when removing the buffer member 17 from the solar cell panel 10, a bigger force than the time of attachment is needed.
Thus, the buffer member 17 of this embodiment has a structure that is easy to attach and difficult to come off.

And it is set as the structure which clamps the solar cell panel 10 from upper and lower in this way, Between the upper board part 62 and the upper surface of the solar cell panel 10, Between the standing board part 61 and the ridge side end surface of the solar cell panel 10, The lower board part 60 When a large number of gaps are formed between the solar cell panel 10 and the lower surface of the solar cell panel 10, it can be easily moved in the direction perpendicular to the eaves-ridge direction (longitudinal direction of the buffer member 17).
That is, as shown in FIG. 8, the buffer member 17 can be easily slid in the longitudinal direction of the solar cell panel 10 with the buffer member 17 attached to the solar cell panel 10.

  As shown in FIGS. 9 and 10, the intermediate mounting bracket 6 includes a fixed portion constituting member 120, an intermediate plate member 121, and a pressing plate member 122.

  As shown in FIG. 10, the fixing member 120 is formed by bending a single plate, and has a lower plate member 125 and an upper plate member 126, both of which are connected by an upright portion 127. It has a shape. That is, the lower plate member 125 has a flat plate shape, and the front side end portion in the longitudinal direction is folded back 180 degrees to form the upper plate member 126.

  The lower plate member 125 and the upper plate member 126 both extend in the eaves-ridge direction (front-rear direction), and are opposed to each other with a slight gap in the vertical direction. The length of the upper plate member 126 is longer than the length of the lower plate member 125, and more specifically, is about two to three times longer.

As shown in FIG. 10, a part of the upper plate member 126 is convex upward, and has a low position portion having a relatively low height and a high position portion having a relatively high height. It has become. More specifically, a front end side (eave side) portion and a rear end side (ridge side) portion are low position portions, and a portion therebetween is a high position portion.
The high position portion occupies about one-third to one-fourth of the entire upper plate member 126 and is formed at a position facing the lower plate member 125.

In addition, a hook portion 128 for hooking cables (the positive side cable 19 and the negative side cable 20) is formed in the lower position portion located on the rear end side than the higher position portion.
The hook portion 128 is formed by cutting a substantially “U” -shaped cut into the upper plate member 126 and raising the cut, and each of the hook portions 128 faces the high position portion side (eave side).

  The upper plate member 126 is formed with four holes including two large opening holes 130 and two member fixing holes 131 at a high position. In addition, four holes including two existing holes 132 and two fixing holes 133 are formed in the lower position portion located on the rear side of the higher position portion.

  More specifically, in the high position portion, the two large opening holes 130 are arranged in parallel at a predetermined interval in the left-right direction, and two members located on the front side (eave side) of the two large opening holes 130 The fixing holes 131 are also arranged in parallel at a predetermined interval in the left-right direction. At this time, the two large opening holes 130 are equal in distance from the center portion in the left-right direction of the high position portion, and the two member fixing holes 131 are also separated from the center portion in the left-right direction of the high position portion. The distance is equal. The distance between the two large opening holes 130 is longer than the distance between the two member fixing holes 131.

  In the low position portion located on the rear side of the high position portion, the two existing holes 132 are arranged in parallel in the left-right direction near the front end, and the two fixing holes 133 are arranged in the left-right direction near the rear end. In parallel with a predetermined interval. Of these, the two fixing holes 133 are both elongated holes extending in the eaves-ridge direction (front-rear direction).

Here, the lower plate member 125 is also provided with four through holes 134, which are arranged in two rows and two columns. Note that only two are shown in FIG. 11, and the other two are not shown.
Each of these through holes 134 is formed one below the two large opening holes 130 and one below each of the two existing holes 132. The through hole 134 positioned below the large opening hole 130 has an opening diameter smaller than that of the large opening hole 130.

As shown in FIGS. 9 to 11, 12, and the like, the intermediate plate member 121 is made by bending a single plate in a step shape.
That is, the intermediate plate member 121 has a first flat plate portion 135, a first upright plate portion 136, a second flat plate portion 137, and a second upright plate portion 138 sequentially from the rear side to the front side. It is provided.

As shown in FIG. 12, two long holes 139 are formed in the first flat plate portion 135. The long hole 139 extends to the wall surface of the first upright plate portion 136, and more specifically, is a long hole extending over the first flat plate portion 135 and the first upright plate portion 136.
A part of the long hole 139 formed in the first upright plate part 136 has a substantially rectangular shape when viewed from the back, and the length in the width direction is formed in the first flat plate part 135 of the same long hole 139. It is longer than the part.

More specifically, the portion formed in the first upright plate portion 136 of the long hole 139 has a size through which the head of the screw 140 can pass. On the other hand, the width of the portion formed in the first flat plate portion 135 is designed to have such a dimension that the neck portion of the screw 140 can pass but the head cannot pass.
The second upright plate portion 138 is provided with two fastening holes 141 as shown in FIG.

  The pressing plate member 122 is a member having a cross-sectional shape of “L” shape, and a front plate portion 143 and a folded portion 144 are formed. The front plate portion 143 is provided with two fastening holes 145.

  Next, the assembly structure of the intermediate mounting bracket 6 will be described.

  As shown in FIGS. 9 and 12, the intermediate mounting member 6 of the present embodiment has the intermediate plate member 121 mounted on the fixing member constituting member 120, and the presser plate member 122 attached to the intermediate plate member 121. ing.

  That is, with the first flat plate portion 135 of the intermediate plate member 121 placed on the high position portion of the fixed portion constituting member 120, the screw 140 is inserted into the long hole 139, and the fixed portion constituting member 120 and the intermediate plate member are inserted. 121 is fixed.

In the present embodiment, as shown in FIG. 9, the long hole 139 extends over the first flat plate portion 135 and the first upright plate portion 136 that intersect substantially vertically, and the first upright plate portion. The width of the portion formed in 136 is wider than the width of the portion formed in the first flat plate portion 135. And in the part formed in the 1st upright board part 136, the head of the screw | thread 140 can pass.
For this reason, when the screw 140 is loosened and the head portion of the screw 140 is separated from the upper surface of the first flat plate portion 135, the screw 140 is engaged with the member fixing hole 131 of the fixing member 120. The intermediate plate member 121 can be slid and moved in and out of the state.

  The holding plate member 122 abuts the back surface side of the front plate portion 143 on the surface of the second upright plate portion 138, and overlaps the fastening hole 141 of the second upright plate portion 138 and the fastening hole 145 of the front plate portion 143. In the combined state, a fastening element such as a screw is inserted and fixed to the intermediate plate member 121.

  As shown in FIGS. 9 and 11, the intermediate mounting bracket 6 of the present embodiment has a structure including a first recess 150, a second recess 151 (holding recess), and a third recess 152 (holding recess). ing.

The 1st recessed part 150 is comprised by the lower board member 125 and the upper board member 126, and is a recessed part opened to the back side (ridge side).
The second recess 151 is configured by a part of the upper plate member 126 and a part of the intermediate plate member 121 positioned thereon, and is a recess that opens in a direction opposite to the first recess 150.
The third concave portion 152 is a concave portion that is configured by a part of the intermediate plate member 121 and the pressing plate member 122 positioned thereon and opens in the same direction as the first concave portion 150.
That is, the intermediate mounting bracket 6 includes a first recess 150 that opens to one side of the intermediate mounting bracket 6, a third recess 152 that opens in the same direction as the first recess 150, and a direction opposite to the first recess 150. A second recess 151 is formed in the opening.

Note that a panel protection member is also attached to the intermediate mounting bracket 6 at a portion that holds the solar cell panel 10. That is, the standing wall surface and the ceiling surface of each of the second recess portion 151 and the third recess portion 152 are covered with the panel protection member.
These panel protective members not only function as protective members that prevent damage to the solar cell panel 10 due to contact with the metal fittings, but also seals that prevent rainwater and the like from entering between the solar cell panel 10 and the metal fittings. Also functions as a material.

  Then, the construction method of the roof structure 1 of this embodiment is demonstrated in detail, referring drawings.

The roof structure 1 of this embodiment forms a roof base | substrate, and arranges the slate tile 2 in a line form and multiple steps | paragraphs on it. That is, it is set as the state which mounted the several slate tile 2 so that it may have a planar expansion on a roof base | substrate. And when this slate roof tile 2 is mounted, the eaves tip mounting bracket 5 and the intermediate mounting bracket 6 are mounted in parallel.
That is, in this embodiment, the foundation roof structure 3 is constructed prior to the installation of the solar cell module 4.

First, as shown in FIG. 13, an eaves edge drainer (not shown) is attached to the eaves of the roof base, and the eaves attachment fitting 5 is placed thereon.
Here, in the present embodiment, a plurality of eaves mounting brackets 5 are attached to the roof base. Thus, when attaching the several eaves attachment metal fittings 5, it is set as the state arrange | positioned close to the space | interval of the left-right direction (parallel direction) so that a clearance gap may not be made when it sees from the front side.

  And the eaves side 1st stage slate roof tile 2a is attached. In the present embodiment, two slate roof tiles 2a on the eaves side are attached in a stacked state. That is, the slate tile 2a-1 positioned below is attached on the roof base (not shown in FIG. 13, refer to FIG. 15, etc.), and the slate tile 2a-2 positioned above to cover the slate tile 2a-1 It is attached.

In addition, the slate tile 2a-1 located below has a shorter length in the eaves ridge direction than the slate tile 2a-2 located above. Thus, since the slate roof tile 2a-2 positioned above is larger than the slate roof tile 2a-1 positioned below, the entire area of the slate roof tile 2a-1 positioned below is positioned above the slate roof tile 2a-2. It is in a state covered with. In other words, the slate roof tile 2a-1 located below is not exposed to the outside.
Moreover, the attachment hole 12 of the lower slate roof tile 2a-1 is in the state located in the eaves side rather than the attachment hole 12 of the upper slate roof tile 2a-2. In other words, the mounting hole 12 of the lower slate roof tile 2a-1 and the mounting hole 12 of the upper slate roof tile 2a-2 are arranged at positions shifted in the eaves-ridge direction. As a result, the mounting hole 12 of the lower slate roof tile 2a-1 is covered with a portion where the mounting hole 12 of the upper slate roof tile 2a-2 is not formed, and rainwater or the like does not enter. ing.

Further, as shown in FIGS. 14 and 15, the eave side second-stage slate roof tile 2 b is attached.
This slate roof tile 2b is disposed in a state where a part of the slate roof tile 2b is overlapped with the first-stage slate roof tile 2a that has been laid. Then, a fastening element such as a nail is inserted into the mounting hole 12 of the slate tile 2b and fixed to the roof base, and the intermediate mounting bracket 6 is mounted in parallel with this process.
As a recommended procedure, as shown in FIGS. 14 and 13, the intermediate plate member 121 is removed from the intermediate mounting bracket 6 (see FIG. 8 and the like), and only the fixing member constituting member 120 is fixed in advance. preferable.

  More specifically, as shown in FIG. 15, the fixing member constituting member 120 is placed on the slate roof tile 2 b placed in advance, and the four through holes 134 (see FIG. 9) of the lower plate member 125 are placed. Among them, the upper plate member 126 is attached using one of the two through holes 134 positioned below the large opening hole 130. That is, the through hole 134 of the lower plate member 125 and one of the four mounting holes 12 of the slate roof tile 2b are overlapped, and a fastening element such as a nail is inserted through these two holes.

  That is, the upper plate member 126 exists above the lower plate member 125, but the large opening hole 130 is provided at a position corresponding to the upper portion of the through hole 134 of the lower plate member 125. The fastening element can be inserted through the through hole 134 by passing through. Furthermore, since the large opening hole 130 is larger than the through hole 134, the driver can easily rotate.

And when fixation of the eaves side 2nd stage slate roof tile 2b is completed, as shown in FIG. 16, the 3rd stage slate roof tile 2c is attached.
When attaching the third-stage slate roof tile 2c, the eaves side end of the slate roof tile 2c is inserted into the first recess 150 of the intermediate mounting bracket 6 as shown in FIG. And the eaves side edge part of the slate roof tile 2c will be in the state which covered the through-hole 134 of the lower board member 125 located in the inside of the 1st recessed part 150. FIG. That is, in the lower part of the upper plate member 126, the third-stage slate roof tile 2c exists throughout the entire area.
This can prevent rainwater from entering the through hole 134.

  In this state, either one of the fixing holes 133 provided from the rear end of the upper plate member 126 of the intermediate mounting bracket 6 is matched with one of the mounting holes 12 of the third-stage slate roof tile 2c. The intermediate mounting bracket 6 is fixed by inserting a fastening element such as a nail into the both.

Thereafter, as shown in FIG. 18, the fourth and subsequent slate roof tiles 2 are attached, and in the same manner as described above, the intermediate mounting bracket 6 (fixing member constituting member 120) together with the slate roof tiles 2 as necessary. To fix.
At this time, the intermediate mounting bracket 6 (fixed portion constituting member 120) is in a state where the ridge side portion is covered with the slate roof tile 2 located on the ridge side. As a result, the two fixing holes 133 of the upper plate member 126 are covered with the slate roof tile 2, and rainwater can be prevented from entering from the fixing holes 133. Moreover, the attachment hole 12 of the slate tile 2 on the eaves side is covered with the slate tile 2 on the ridge side. As a result, the intrusion of rainwater from the mounting hole 12 can be prevented.
Then, by attaching the slate tile 2 from the eaves side to the ridge, the laying of the slate tile 2 is completed on the roof base, and the foundation roof structure 3 is completed.

  Subsequently, the solar cell module 4 is installed on the foundation roof structure 3. Further, as a recommended procedure, it is desirable to carry out wiring of the solar cell module 4 when the solar cell module 4 is fixed.

The solar cell module 4 is fixed on the roof in order from the eaves side. Accordingly, first, the eaves-side first-stage solar cell module 4a is fixed.
Here, as shown in FIG. 19, the eaves-end fitting 5 is provided with a holding portion 63 in the vicinity of the upper end. The holding portion 63 is in a state where the ridge side portion is open, and is a portion that is depressed toward the eaves side.

In this embodiment, as shown in FIGS. 19 and 20, the eaves side end of the solar cell module 4 is fitted into the holding portion 63 of the eaves tip mounting bracket 5, and the ridge side end of the solar cell module 4 a is placed. The part is placed on the intermediate mounting bracket 6a (fixed part constituting member 120) attached together with the second-stage slate roof tile 2b.
More specifically, the ridge-side end portion of the solar cell module 4a is placed on the low position portion located on the front side (eave side) of the fixed portion constituting member 120 (see FIG. 20).

And as FIG. 20 shows, the intermediate | middle board member 121 and the pressing board member 122 are fixed to the fixing | fixed part structural member 120 in the state which mounted the ridge side edge part of the solar cell module 4a on the fixing | fixed part structural member 120. FIG. And attach.
As a result, the solar cell module 4a faces the eaves side because the eave side engages with the holding portion 63 of the eaves tip mounting bracket 5, and the ridge side engages with the second recess 151 of the intermediate mounting bracket 6a. Both sides are held, and the base roof structure 3 cannot be detached.

When the eaves-side first-stage solar cell module 4a is attached, subsequently, cable wiring is performed between the adjacent solar cell modules 4a. That is, as shown in FIG. 21, the positive electrode side cable 19 on one side of the adjacent solar cell module 4 and the negative electrode side cable 20 on the other side are connected.
In the present embodiment, the cable that has been wired is engaged with the hook portion 128 of the intermediate mounting bracket 6. By doing in this way, processing of a cable becomes easy.

  At this time, the eaves-side first-stage solar cell modules 4a are in parallel in a direction orthogonal to the eaves ridge direction, that is, in a direction parallel to the building ridge. At this time, each solar cell module 4a is mounted so that the longitudinal direction thereof is a direction orthogonal to the eaves-ridge direction.

Here, as described above, the buffer member 17 is attached to the ridge side of the solar cell module 4a. Therefore, as shown in FIG. 21, the buffer member 17 and the intermediate mounting bracket 6a are in a state of being aligned in a straight line in a direction orthogonal to the eaves-ridge direction. That is, the intermediate mounting bracket 6a is located outside the buffer member 17 and at a position separated in a direction parallel to the building ridge. In other words, the shock-absorbing member 17 is located outside the intermediate mounting bracket 6a and at a position separated in a direction parallel to the building ridge. Thus, the buffer member 17 and the intermediate mounting bracket 6a are in parallel with each other with a predetermined interval.
More specifically, one or two (plural) buffer members 17 are located between the two intermediate mounting brackets 6a.

  Further, as described above, although the buffer member 17 is difficult to be detached from the solar cell panel 10, it can be easily slid in the direction orthogonal to the eaves-ridge direction (longitudinal direction of the solar cell panel 10). It has become. From this, in a state where the buffer member 17 and the intermediate mounting bracket 6a are arranged in parallel with each other at a predetermined interval, the buffer member 17 can be slid in a direction parallel to the building ridge to adjust the position. That is, position adjustment can be performed as necessary.

Subsequently, the second-stage solar cell module 4b on the eaves side is laid.
The eaves side second-stage solar cell module 4b is fixed by the intermediate mounting bracket 6 on both the eaves side and the ridge side. That is, the eaves side of the solar cell module 4b is inserted into the third recess 152 of the intermediate mounting bracket 6a located on the eaves side as shown in FIG.

  At this time, the ridge side of the solar cell module 4b is placed on the intermediate mounting bracket 6b (fixed member constituting member 120) further located on the ridge side, similarly to the solar cell module 4a on the first eave side. (See FIG. 23). Then, as in the case described above, the intermediate plate member 121 and the pressing plate member 122 are attached to the fixed portion constituting member 120 in this state. As a result, the eaves side of the solar cell module 4b engages with the third recess 152 of the intermediate mounting bracket 6a located on the eave side, and the second recess 151 of the intermediate mounting bracket 6b whose ridge side is positioned on the ridge side. Are engaged with each other, the opposite sides of the solar cell module 4b are held and cannot be detached from the foundation roof structure 3.

Similarly, the solar cell modules 4 on the eaves side third and subsequent stages are installed as necessary. And the cable extended from one of the solar cell modules 4 is connected to a drawing-in cable (not shown) as needed.
When the installation of the desired number of stages is completed, the rain closing plate 11 is installed on the ridge side of the solar cell module 4 at the uppermost part.
Thereby, the roof structure 1 of this embodiment is completed (refer FIG. 1).

  Here, as shown in FIG. 24, the ridge side portion of the solar cell module 4a located on the eave side and the eave side portion of the solar cell module 4b located on the ridge side are overlapped when viewed in plan. It has become. More specifically, the ridge side portion of the solar cell module 4a located on the eave side is covered with the eave side portion of the solar cell module 4b arranged at a position apart upward. And the buffer member 17 located in the ridge side part of the solar cell module 4a is also covered with the solar cell module 4b located on the ridge side, and is not exposed to the outside. As a result, the buffer member 17 is not exposed to direct sunlight or rain and wind, and therefore, the aged deterioration of the buffer member 17 can be suppressed.

25, a slight gap is formed between the upper plate portion 62 of the buffer member 17 attached to the eaves-side solar cell module 4a and the solar cell module 4b located on the ridge side. It has become.
A slight gap is also formed between the lower plate portion 60 of the buffer member 17 attached to the eaves-side solar cell module 4 a and the slate roof tile 2.
That is, the buffer member 17 is not in contact with the solar cell module 4b located above and the slate roof tile 2 located below in a normal state.

Here, a case where snow or the like is piled up on the solar cell module 4b on the ridge side and the solar cell module 4b on the ridge side is bent due to the load will be described.
In this case, the eaves side end portion of the solar cell module 4b is deformed so as to be directed downward, and the back surface thereof comes into contact with the upper surface of the upper plate portion 62 of the buffer member 17. Thus, the load applied to the upper solar cell module 4b can be received by the lower solar cell module 4a to which the buffer member 17 is attached. That is, the solar cell module 4b can be prevented from being damaged by dispersing the load applied to the upper solar cell module 4b.
Furthermore, since the back surface of the upper solar cell module 4b does not directly contact the upper surface of the lower solar cell module 4a (a surface forming the same plane as the light receiving surface), damage caused by such contact is prevented. it can.

In addition, when a load is applied to the upper solar cell module 4b from this state, the lower solar cell module 4a may be bent.
However, in this case, the ridge side end of the solar cell module 4a is deformed so as to go downward, and the lower plate portion 60 of the buffer member 17 comes into contact with the slate roof tile 2. That is, since it becomes possible to receive and disperse | distribute a load with a roof surface (slate tile 2), damage to the upper side solar cell module 4b and the lower side solar cell module 4a can be prevented.
At this time, since the lower solar cell module 4a does not directly contact the slate roof tile 2, damage due to such contact can be prevented.

  In the solar cell module 4 of the present embodiment, the upper end surface of the long side reinforcing member 50 and the upper surface (light receiving surface) of the solar cell panel 10 are in the same plane (see FIG. 6 and the like). That is, the light receiving surface of the solar cell module 4 is in a state in which a flat surface having no unevenness is formed over the entire area. As a result, when snow accumulates on the solar cell module 4, the accumulated snow flows without any stagnation to the eaves side end and falls to the eaves side as it is. That is, it is difficult for snow to stay on the solar cell module 4, and a large snow load is difficult to be applied to the solar cell module 4.

In the above-described embodiment, the example of the reinforcing member 16 including the long-side reinforcing member 50 having the back surface protecting plate 53 and the end surface protecting plate 54 and the short-side reinforcing member 51 having the upright plate shape is shown. It is not limited.
For example, as shown in FIGS. 26 and 27, the long-side reinforcing member 350 (first reinforcing member) and the short-side reinforcing member 51 are both in the form of a standing plate, and both have a structure in which the back surface protection plate 53 is not provided. The member 316 may be used. And the attachment hole 355 may be formed in the end surface of the longitudinal direction of the long side reinforcement member 350, you may make it connect with the attachment hole 56 of the short side reinforcement member 51, and may insert a fastening element. In other words, the end face in the longitudinal direction of the long side reinforcing member 350 and the portion of the inner side surface of the short side reinforcing member 51 located at the end in the longitudinal direction may be contacted and fixed integrally.

  In the above-described embodiment, the length of the end face protection plate 54 and the short side reinforcing member 51 in the vertical direction (thickness direction of the solar cell panel 10) and the length in the thickness direction of the solar cell panel 10 are the same length, and the end face The example of the solar cell module 4 in which the upper surface of the protection plate 54 and the short side reinforcing member 51 and the light receiving surface of the solar cell panel 10 form the same plane is shown. However, the present invention is not limited to this, and the upper surfaces of the end face protection plate 54 and the short-side reinforcing member 51 may be located on the back side of the light receiving surface of the solar cell panel 10. That is, the upper surface of the end face protection plate 54 and the short side reinforcing member 51 and the light receiving surface of the solar cell panel 10 may be continuous through a step.

In the above-described embodiment, the length of the long side reinforcing member 50 is the same as the long side of the solar cell panel 10, and the length of the short side reinforcing member 51 is slightly longer than the length of the short side of the solar cell panel 10. Although an example of the reinforcing member 16 is shown, the present invention is not limited to this.
For example, the length of only the end face protection plate in the long side reinforcing member 50 is slightly longer than the long side of the solar cell panel 10, and the length of the short side reinforcing member is the same length as the short side of the solar cell panel 10. It is good.

  In this case, an attachment hole that penetrates the end face protection plate in the thickness direction may be provided at an end portion in the longitudinal direction of the end face protection plate, and an attachment hole may be provided in the end face in the longitudinal direction of the short side reinforcing member. That is, the inner side surface of the end face protection plate and the end surface in the longitudinal direction of the short side reinforcing member may be fixed integrally with each other.

  In the above-described embodiment, the example of the reinforcing member 16 including the long-side reinforcing member 50 having the back surface protecting plate 53 and the end surface protecting plate 54 and the short-side reinforcing member 51 having the upright plate shape is shown. Not limited to this, the long side reinforcing member may be a standing plate shape, and the short side reinforcing member may be a shape having a back surface protection plate and an end surface protection plate.

  Moreover, you may be the structure which forms a back surface protection board in both a long side reinforcement member and a short side reinforcement member. In this case, one or both of the back surface protection plates may be slightly shorter than the length of the side of the adjacent solar cell panel 10.
