（実施例） 図１ないし図５は本発明に係る太陽電池モジュールと、その折版屋根への取り付け構造の実施例を示す。図５において太陽電池モジュールＭは、ベース体１と、ベース体１に装着される電池本体２とで構成する。ベース体１は、一対の締結壁３と、締結壁３に連続して上向きに立ち上がる一対の脚壁４と、両脚壁４の上端どうしを繋ぐ組付壁５とを一体に備えた横長のパネル体からなり、鋼板をロール成形して、あるいはベンダー成型により形成する。 (Example) FIG. 1 thru | or FIG. 5 shows the Example of the solar cell module which concerns on this invention, and the attachment structure to the folding plate roof. In FIG. 5, the solar cell module M includes a base body 1 and a battery body 2 attached to the base body 1. The base body 1 is a horizontally long panel that is integrally provided with a pair of fastening walls 3, a pair of leg walls 4 that rises continuously upward from the fastening wall 3, and an assembly wall 5 that connects the upper ends of both leg walls 4. It consists of a body, and a steel plate is formed by roll forming or bender forming.

ベース体１の締結壁３および脚壁４には、隣接する折版屋根材１０の連結構造に応じて溝６あるいはボルト穴７のいずれかが形成される。詳しくは、図３に示すように隣接する折版屋根材１０どうしが、山部分１１の上面上方に突出するはぜ締め構造１３で連結してある場合には、締結壁３および脚壁４に、図５に示すようになぜ締め構造１３を跨ぐための溝６を一定間隔おきに切り欠き形成する。溝６の隣接ピッチは、横方向に隣接するはぜ締め構造１３の隣接ピッチに一致させる。   Either the groove 6 or the bolt hole 7 is formed in the fastening wall 3 and the leg wall 4 of the base body 1 according to the connection structure of the adjacent folded roof materials 10. Specifically, as shown in FIG. 3, when the adjacent folding roof materials 10 are connected by a fastening structure 13 protruding above the upper surface of the mountain portion 11, the fastening walls 3 and the leg walls 4 are connected. As shown in FIG. 5, the grooves 6 for straddling the fastening structure 13 are cut out at regular intervals. The adjacent pitch of the groove | channel 6 is made to correspond with the adjacent pitch of the brazing structure 13 adjacent to a horizontal direction.

また、図７に示すように隣接する折版屋根材１０の山部分１１どうしが、タイトフレーム１５に対してボルト１８で連結固定してある場合には、締結壁３にボルト１８を挿通するためのボルト穴７を一定間隔おきに形成する。ボルト穴７の隣接ピッチはボルト１８の横方向隣接ピッチに一致させる。   Further, as shown in FIG. 7, when the adjacent mountain portions 11 of the folded roofing material 10 are connected and fixed to the tight frame 15 with bolts 18, the bolts 18 are inserted into the fastening walls 3. The bolt holes 7 are formed at regular intervals. The adjacent pitch of the bolt holes 7 is matched with the lateral adjacent pitch of the bolts 18.

図１に示すように、電池本体２は、プラスチックフィルム基板２０の表面に太陽電池層２１を形成したフィルム型のアモルファス太陽電池からなる。フィルム型のアモルファス太陽電池は、ガラス基板の表面に太陽電池層を形成した結晶系太陽電池に比べて、単位面積あたりの重量を軽量化できるうえ、湾曲変形できるので曲面に沿って配置できる特長を有する。因みに、この実施例の電池本体２は、１平方ｍ当り１kgの重量しかなく、従来の結晶系太陽電池に比べて１０分の１にまで軽量化できる。   As shown in FIG. 1, the battery body 2 is a film-type amorphous solar cell in which a solar cell layer 21 is formed on the surface of a plastic film substrate 20. Film-type amorphous solar cells can reduce the weight per unit area compared to crystalline solar cells with a solar cell layer formed on the surface of a glass substrate, and can be curved and deformed. Have. Incidentally, the battery body 2 of this embodiment has a weight of only 1 kg per square meter, and can be reduced to 1/10 of the weight of the conventional crystalline solar battery.

プラスチックフィルム基板２０は、耐候性、なかでも紫外線によって劣化しにくいプラスチック材、例えばフッ素樹脂などを素材にして形成してあり、その片面に太陽電池層２１をプラズマＣＶＤ法で形成する。電池本体２は、プラスチックフィルム基板２０を先の組付壁５に接着することにより、ベース体１と一体化する。図１における符号２２は接着剤層を示す。   The plastic film substrate 20 is made of a plastic material, such as a fluororesin, which is resistant to weathering, especially ultraviolet rays, and a solar cell layer 21 is formed on one surface thereof by a plasma CVD method. The battery body 2 is integrated with the base body 1 by bonding the plastic film substrate 20 to the previous assembly wall 5. Reference numeral 22 in FIG. 1 indicates an adhesive layer.

太陽電池モジュールＭの設置例を図１ないし図４に示す。この設置例における折版屋根材１０は、逆台形状の谷部分１２の両端に山部分１１が形成され、山部分１１の端部にはぜ継手１３ａ・１３ｂが折り曲げ形成してある。隣接する折版屋根材１０の山部分１１は、屋根下地に固定したタイトフレーム１５で受け止め支持され、タイトフレーム１５に固定した吊子１６にはぜ継手１３ａ・１３ｂを締め込むことにより、隣接する折版屋根材１０どうしが連結される。   Examples of installation of the solar cell module M are shown in FIGS. In the folded roofing material 10 in this installation example, crest portions 11 are formed at both ends of the inverted trapezoidal trough portion 12, and joints 13 a and 13 b are bent at the end portions of the crest portion 11. The adjacent peak portion 11 of the folded roofing material 10 is received and supported by a tight frame 15 fixed to the roof base, and is adjacent to the suspension 16 fixed to the tight frame 15 by fastening the joints 13a and 13b. The folded roof materials 10 are connected.

上記のように、隣接する折版屋根材１０どうしが、山部分１１の上方に突出するはぜ締め構造１３を介して連結してある屋根においては、各溝６がはぜ締め構造１３を跨ぐようにしてベース体１を山部分１１の上面に載置し、ベース体１の締結壁３をはぜ締め構造１３に締結した締結金具２５で固定することにより、太陽電池モジュールＭを折版屋根材１０に直接固定する。   As described above, in the roof in which the adjacent folded plate roof materials 10 are connected to each other via the fastening structure 13 protruding above the mountain portion 11, each groove 6 straddles the fastening structure 13. In this manner, the base body 1 is placed on the upper surface of the mountain portion 11 and the fastening wall 3 of the base body 1 is fixed with the fastening metal fitting 25 fastened to the fastening structure 13 so that the solar cell module M is folded. Fix directly to the material 10.

図１および図４において締結金具２５は、クリップ状の金具本体２６と、金具本体２６をはぜ締め構造１３に締結するボルト２７およびナット２８で構成する。金具本体２６は、はぜ締め構造１３の首部１７を挟持する一対の取付脚３０と、両取付脚３０の上部で対向するボルト２７用の締結座３１と、両締結座３１の上端どうしを繋ぐ上壁３２と、取付脚３０の下部に連続する押え壁３３を一体に備えており、厚みが２mm強の鋼材を折り曲げて形成する。締結座３１の幅方向中央にはボルト挿通穴が通設され、その両側に外形が涙滴状の補強リブ３４が膨出形成してある（図４参照）。   1 and 4, the fastening bracket 25 includes a clip-shaped bracket main body 26, and bolts 27 and nuts 28 that fasten the bracket main body 26 to the fastening structure 13. The metal fitting body 26 connects a pair of mounting legs 30 that sandwich the neck portion 17 of the fastening structure 13, a fastening seat 31 for the bolt 27 that is opposed to each other at the upper part of the both mounting legs 30, and upper ends of the fastening seats 31. The upper wall 32 and the presser wall 33 continuous to the lower part of the attachment leg 30 are integrally provided, and a steel material having a thickness of more than 2 mm is bent and formed. A bolt insertion hole is formed in the center of the fastening seat 31 in the width direction, and reinforcing ribs 34 having a teardrop-shaped outer shape are formed on both sides of the fastening seat 31 (see FIG. 4).

垂直の締結座３１に連続する一対の取付脚３０は、部分円弧状に形成されて下すぼまり状に折り曲げられており、その下端に押え壁３３が横向きに折り曲げてある。自由状態における締結金具２５は、取付脚３０と押え壁３３との間の屈折部３５の対向間隔が、はぜ締め構造１３の左右幅より僅かに大きく設定してあるが、図１に示すように、対向する締結座３１をボルト２７とナット２８で締め付けて固定した状態では、屈折部３５がはぜ締め構造１３の首部１７を左右に挟持し、押え壁３３が締結壁３を山部１１と協同して上下に挟持固定している。   A pair of mounting legs 30 continuing to the vertical fastening seat 31 is formed in a partial arc shape and is bent in a conical shape, and a presser wall 33 is bent sideways at the lower end thereof. As shown in FIG. 1, the fastening bracket 25 in the free state is set so that the facing distance of the refracting portion 35 between the mounting leg 30 and the pressing wall 33 is slightly larger than the left and right width of the hose fastening structure 13. In addition, in a state where the opposing fastening seats 31 are fastened and fixed with bolts 27 and nuts 28, the refracting portion 35 holds the neck portion 17 of the fastening structure 13 to the left and right, and the presser wall 33 connects the fastening wall 3 to the mountain portion 11. It is clamped and fixed up and down in cooperation with.

ボルト２７の引き寄せ締結力を利用して、押え壁３３を締結壁３に強固に押し付けるために、取付脚３０の下半部分に傾斜壁３６を設けている。締結金具２５をはぜ締め構造１３に上方から係止したのちボルト２７を締め付けると、傾斜壁３６がはぜ締め部分の下あご部分に接当し、下あご部分から受ける締め付け反力によって、締結金具２５の全体が徐々に下向きに押し下げられる。その結果、押え壁３３が締結壁３に密着して、溝６に臨む締結壁３を山部分１１およびタイトフレーム１５と協同して強固に挟持固定できる。   In order to firmly press the holding wall 33 against the fastening wall 3 by using the pulling fastening force of the bolt 27, an inclined wall 36 is provided in the lower half portion of the mounting leg 30. When the bolt 27 is tightened after the fastener 25 is locked to the fastening structure 13 from above, the inclined wall 36 comes into contact with the lower jaw part of the fastening part and is fastened by the fastening reaction force received from the lower jaw part. The entire metal fitting 25 is gradually pushed downward. As a result, the presser wall 33 comes into close contact with the fastening wall 3, and the fastening wall 3 facing the groove 6 can be firmly clamped and fixed in cooperation with the mountain portion 11 and the tight frame 15.

同様にして、はぜ締め構造１３とベース体１との交差部分を締結金具２５で締結することにより、左右に長い太陽電池モジュールＭを、屋根の軒棟方向と直交する状態で設置できる。なお、太陽電池モジュールＭの両端は、図２に示すように、山部分１１から片持ち梁状に突出ていてもよい。折版屋根材１０の山部分１１の隣接ピッチやはぜ締め構造１３にもよるが、山部分１１の隣接ピッチが比較的小さい場合には、図３に示すように山部分１１の隣接ピッチの２ピッチ（あるいは３ピッチ）おきに、はぜ締め構造１３とベース体１との交差個所を締結金具２５で締結すればよい。また、隣接するはぜ締め構造１３の隣接ピッチが大きい場合には、はぜ締め構造１３とベース体１との交差個所の全てを締結金具２５で締結するとよい。   Similarly, by fastening the intersecting portion between the helical fastening structure 13 and the base body 1 with the fastening bracket 25, the solar cell module M that is long on the left and right can be installed in a state orthogonal to the roof eaves direction. Note that both ends of the solar cell module M may protrude from the mountain portion 11 in a cantilever shape as shown in FIG. Although it depends on the adjacent pitch of the mountain portion 11 of the folded roofing material 10 and the fastening structure 13, when the adjacent pitch of the mountain portion 11 is relatively small, as shown in FIG. What is necessary is just to fasten the intersection part of the screw fastening structure 13 and the base body 1 with the fastening bracket 25 every 2 pitches (or 3 pitches). In addition, when the adjacent pitch of the adjacent fastening structures 13 is large, all the intersections between the fastening structures 13 and the base body 1 may be fastened with the fastening fittings 25.

太陽電池モジュールＭを、図２に示すように軒棟方向へ隣接して設置する場合には、例えば最下段の太陽電池モジュールＭの軒先側に位置する締結壁３のみを折版屋根材１０に固定したのち、その上方に次段の太陽電池モジュールＭを所定間隔をあけて載置する。そのうえで、上下のベース体１・１の間に露出するはぜ締め構造１３に締結金具２５を締結して、下段のベース体１の棟側に位置する締結壁３と、上段のベース体１の軒先側に位置する締結壁３の両者を、締結金具２５で同時に固定する。   When the solar cell module M is installed adjacent to the eave building as shown in FIG. 2, for example, only the fastening wall 3 positioned on the eaves side of the lowermost solar cell module M is used as the folded roof material 10. After fixing, the next-stage solar cell module M is placed at a predetermined interval above it. In addition, the fastening bracket 25 is fastened to the screw fastening structure 13 exposed between the upper and lower base bodies 1, 1, and the fastening wall 3 positioned on the ridge side of the lower base body 1 and the upper base body 1 are connected. Both of the fastening walls 3 located on the eaves side are simultaneously fixed by the fastening fittings 25.

以後、同様にして複数の太陽電池モジュールＭを軒棟方向へ隣接する状態で固定し、さらに横方向へ隣接する状態で設置することにより、図２に示すような合計面積が大きく、発電電力量が大きな太陽光発電システムを構築することができる。図示していないが、個々の太陽電池モジュールＭで発電された電力は、個々のモジュールから導出された出力ケーブルを介して出力調整器へ出力され、そこで電圧を調整したのち交流電流に変換されて商用電源などに供給される。   Thereafter, in the same manner, a plurality of solar cell modules M are fixed so as to be adjacent to each other in the eave building direction, and further installed in a state adjacent to the horizontal direction, so that the total area as shown in FIG. Can build a large photovoltaic system. Although not shown, the electric power generated by each solar cell module M is output to an output regulator via an output cable derived from each module, where the voltage is adjusted and then converted into an alternating current. Supplied to commercial power.

金具本体２６の上壁３２の上面には、仮設枠４０を支持するための枠受座４１が、上壁３２の内面側から挿通されるボルト４２と、上壁３２の上面側からボルト４２にねじ込まれるナット４３とで締結固定してある。枠受座４１は正方形または円形に切断した鋼板で形成されており、その中央部分にボルト４２用の挿通穴が通設してある。図４に示すように、仮設枠４０はハット形断面のチャンネル材からなり、そのチャンネル溝壁に先のボルト４２を挿通するための挿通穴４４が形成してある。挿通穴４４の隣接ピッチは、横方向のボルト列を構成するボルト４２の隣接ピッチに一致させてある。必要があれば、挿通穴４４の隣接ピッチが、軒棟方向のボルト列を構成するボルト４２の隣接ピッチに一致させてある仮設枠４０も併せて設けることができる。   On the upper surface of the upper wall 32 of the metal fitting body 26, a frame receiving seat 41 for supporting the temporary frame 40 is inserted from the inner surface side of the upper wall 32 to the bolt 42 from the upper surface side of the upper wall 32. The nut 43 is screwed and fixed. The frame receiving seat 41 is formed of a steel plate cut into a square or a circle, and an insertion hole for the bolt 42 is provided in the center portion thereof. As shown in FIG. 4, the temporary frame 40 is made of a channel material having a hat-shaped cross section, and an insertion hole 44 through which the bolt 42 is inserted is formed in the channel groove wall. The adjacent pitch of the insertion hole 44 is made to correspond to the adjacent pitch of the volt | bolt 42 which comprises a volt | bolt row | line | column of a horizontal direction. If necessary, a temporary frame 40 in which the adjacent pitch of the insertion holes 44 is matched with the adjacent pitch of the bolts 42 constituting the bolt row in the eave building direction can also be provided.

各挿通穴４４がボルト４２に外嵌する状態で、仮設枠４０を枠受座４１の上面に載置することにより、仮設枠４０を太陽電池モジュールＭと平行に支持でき、あるいは仮設枠４０を太陽電池モジュールＭと直交する状態で支持できる。いずれにしろ、枠受座４１で支持した仮設枠４０を足場とすることにより、既設の太陽電池モジュールＭを踏みつけることなく、そのメンテナンスや、交換作業などを効果的に行うことができる。必要があれば、仮設枠４０の上面に足場パネルを締結してもよい。   The temporary frame 40 can be supported in parallel with the solar cell module M by placing the temporary frame 40 on the upper surface of the frame receiving seat 41 in a state where each insertion hole 44 is fitted over the bolt 42. It can support in the state orthogonal to the solar cell module M. In any case, by using the temporary frame 40 supported by the frame receiving seat 41 as a scaffold, the maintenance or replacement work can be effectively performed without stepping on the existing solar cell module M. If necessary, a scaffold panel may be fastened to the upper surface of the temporary frame 40.

上記の実施例では、隣接する折版屋根材１０どうしが丸はぜ構造のはぜ締め構造１３で連結してある場合について説明したが、折版屋根材１０どうしが角はぜ構造のはぜ締め構造１３で連結してある場合には、図６に示す金具本体２６を使用する。角はぜ構造のはぜ締め構造１３では、はぜ締め部分が吊子１６の一側方においてかしめ変形される。そのため、金具本体２６の一方の取付脚３０は、締結座３１に連続して垂直に形成し、他方の取付脚３０に限って傾斜壁３６を形成する。他は先の実施例と同じであるので、同じ部材に同じ符号を付してその説明を省略する。以下の実施例についても同様に扱う。   In the above-described embodiment, the case where the adjacent folding roof materials 10 are connected to each other by the round-tightening structure 13 is described. When the fastening structure 13 is used for connection, the metal fitting body 26 shown in FIG. 6 is used. In the corner tightening structure 13, the bolting portion is caulked and deformed on one side of the hanging member 16. Therefore, one mounting leg 30 of the metal fitting body 26 is formed continuously and perpendicularly to the fastening seat 31, and only the other mounting leg 30 forms an inclined wall 36. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted. The following examples are similarly treated.

金具本体２６をボルト２７ではぜ締め構造１３に締結した状態においては、垂直の取付脚３０と傾斜壁３６とではぜ締め構造１３が挟持固定されて、屈曲部３５が首部１７と接当することはない。ボルト２７を完全に締結した状態では、先の実施例と同様に、傾斜壁３６がはぜ締め構造１３の下あご部分から締め付け反力を受けるので、押え壁３３を締結壁３に密着させて、溝６に臨む締結壁３を山部分１１およびタイトフレーム１５と協同して強固に挟持固定できる。   In a state where the metal fitting body 26 is fastened to the fastening structure 13 with the bolt 27, the fastening structure 13 is sandwiched and fixed between the vertical mounting leg 30 and the inclined wall 36, and the bent portion 35 contacts the neck portion 17. There is no. In the state in which the bolt 27 is completely fastened, the inclined wall 36 receives the tightening reaction force from the lower jaw portion of the helical tightening structure 13 as in the previous embodiment, so that the presser wall 33 is brought into close contact with the fastening wall 3. The fastening wall 3 facing the groove 6 can be firmly clamped and fixed in cooperation with the mountain portion 11 and the tight frame 15.

図７および図８に、隣接する折版屋根材１０の山部分１１どうしがボルト（剣先ボルト）１８で連結固定してある場合の太陽電池モジュールＭの設置構造を示す。この場合には、タイトフレーム１５の上面で上下に重ねた山部分１１を、ボルト１８、ナット１９、および座金４６などで締結して、隣接する折版屋根材１０どうしを連結するので、ボルト１８、ナット１９、および座金４６をそのまま利用して、太陽電池モジュールＭを折版屋根材１０に直接締結固定する。   7 and 8 show the installation structure of the solar cell module M in the case where the mountain portions 11 of the adjacent folding roof materials 10 are connected and fixed by bolts (sword tip bolts) 18. In this case, the mountain portion 11 that is vertically stacked on the upper surface of the tight frame 15 is fastened with the bolt 18, the nut 19, the washer 46, and the like, and the adjacent folding roof materials 10 are connected to each other. The solar battery module M is directly fastened and fixed to the folded roofing material 10 by using the nut 19 and the washer 46 as they are.

既存の屋根においては、ナット１９および座金４６をボルト１８から取り外したのち、ベース体１のボルト穴７がボルト１８に外嵌する状態で、太陽電池モジュールＭを山部分１１に載置する。この状態でボルト１８に座金４６を組み、ナット１９をボルト１８に締結することによりベース体１を固定して、太陽電池モジュールＭを屋根の軒棟方向と直交する状態で折版屋根１０に直接固定できる。   In the existing roof, after removing the nut 19 and the washer 46 from the bolt 18, the solar cell module M is placed on the mountain portion 11 in a state where the bolt hole 7 of the base body 1 is fitted around the bolt 18. In this state, the washer 46 is assembled to the bolt 18, the nut 19 is fastened to the bolt 18, the base body 1 is fixed, and the solar cell module M is directly applied to the folded roof 10 in a state orthogonal to the roof eaves direction. Can be fixed.

ベース体１に設けたボルト穴７の軒棟方向の隣接ピッチＰ１と、タイトフレーム１５の軒棟方向の隣接ピッチＰ２とは必ずしも一致しないので、太陽電池モジュールＭを屋根の軒棟方向に隣接配置する場合には、タイトフレーム１５の軒棟方向の隣接ピッチＰ２をひとつの基準にしてベース体１を用意する必要がある。多くの場合は、ボルト穴７の軒棟方向の隣接ピッチＰ１に比べて、タイトフレーム１５の軒棟方向の隣接ピッチＰ２が充分に大きいので、前者ピッチＰ１を後者ピッチＰ２の整数分の１とすると、全てのボルト１８をベース体１の締結に利用することができ、新たに追加すべき締結部品を最小限化できる。もちろん前者ピッチＰ１と後者ピッチＰ２とは一致していてもよい。   Since the adjacent pitch P1 in the eave building direction of the bolt holes 7 provided in the base body 1 and the adjacent pitch P2 in the eave building direction of the tight frame 15 do not necessarily coincide, the solar cell module M is arranged adjacent to the roof eave building direction. In this case, it is necessary to prepare the base body 1 with the adjacent pitch P2 in the eave building direction of the tight frame 15 as one reference. In many cases, the adjacent pitch P2 in the eaves direction of the tight frame 15 is sufficiently larger than the adjacent pitch P1 in the eaves direction of the bolt holes 7, so that the former pitch P1 is set to 1 / integer of the latter pitch P2. Then, all the bolts 18 can be used for fastening the base body 1, and fastening parts to be newly added can be minimized. Of course, the former pitch P1 and the latter pitch P2 may coincide with each other.

図８においては、ボルト穴７の軒棟方向の隣接ピッチＰ１を、タイトフレーム１５の軒棟方向の隣接ピッチＰ２の２分の１に設定して、上下に隣接配置したベース体１の締結壁３を上下に重ねた状態で、そのボルト穴７をボルト１８に挿通し、座金４６を組んだのちナット１９をボルト１８に締結することにより、締結壁３を山部分１１およびタイトフレーム１５に締結固定できる。軒棟方向に隣接するタイトフレーム１５の間では、先のボルト１８を利用できないので、上下に重さなる締結壁３をワンサイドボルト４７で山部分１１に締結固定する。   In FIG. 8, the adjacent pitch P <b> 1 in the eave building direction of the bolt holes 7 is set to one half of the adjacent pitch P <b> 2 in the eave building direction of the tight frame 15, and the fastening wall of the base body 1 arranged adjacently in the vertical direction. 3, the bolt hole 7 is inserted into the bolt 18, the washer 46 is assembled, and the nut 19 is fastened to the bolt 18 to fasten the fastening wall 3 to the mountain portion 11 and the tight frame 15. Can be fixed. Since the previous bolt 18 cannot be used between the tight frames 15 adjacent in the eaves-and-ridge direction, the fastening wall 3 that overlaps vertically is fastened and fixed to the mountain portion 11 with the one-side bolt 47.

詳しくは、ベース体１の軒先側の締結壁３をボルト１８に仮固定した状態で、棟側の締結壁３に形成したボルト穴７をガイドにして、山部分１１にワンサイドボルト４７用の締結穴４８をドリルで形成する。こののち、仮固定した太陽電池モジュールＭの棟側に新たな太陽電池モジュールＭ配置し、両モジュールＭの締結壁３・３を上下に重ね、ボルト穴７・７を位置あわせする。この状態でワンサイドボルト４７をボルト穴７・７に上方から差し込み、全体を押さえ込んだ状態でナット４９をねじ込み操作することにより、ねじ軸に外嵌するスリーブ５０の下半側を拡開変形させて、締結壁３を山部分１１に締結固定する。   Specifically, in a state where the fastening wall 3 on the eaves side of the base body 1 is temporarily fixed to the bolt 18, the bolt hole 7 formed in the fastening wall 3 on the ridge side is used as a guide, and the peak portion 11 is used for the one-side bolt 47. The fastening hole 48 is formed by a drill. After that, a new solar cell module M is arranged on the ridge side of the temporarily fixed solar cell module M, the fastening walls 3 and 3 of both modules M are vertically stacked, and the bolt holes 7 and 7 are aligned. In this state, the one-side bolt 47 is inserted into the bolt holes 7 and 7 from above, and the nut 49 is screwed in while the whole is pressed down, so that the lower half side of the sleeve 50 fitted on the screw shaft is expanded and deformed. Then, the fastening wall 3 is fastened and fixed to the mountain portion 11.

以後、ベース体１の締結壁３をボルト１８とワンサイドボルト４７で締結することにより、太陽電池モジュールＭが軒棟方向に隣接でき、その側方に同様のモジュール列を設置することにより、大面積の太陽光発電システムを構築することができる。仮設枠４０は、その挿通穴４４をボルト１８とワンサイドボルト４７に外嵌し、チャンネル溝壁をナット１９・４９の上面に載置することにより、太陽電池モジュールＭと平行に支持できる。   Thereafter, the fastening wall 3 of the base body 1 is fastened with the bolts 18 and the one-side bolts 47 so that the solar cell module M can be adjacent to the eaves ridge, and by installing a similar module row on the side, An area solar power generation system can be constructed. The temporary frame 40 can be supported in parallel with the solar cell module M by fitting the insertion hole 44 to the bolt 18 and the one-side bolt 47 and placing the channel groove wall on the upper surfaces of the nuts 19 and 49.

図９および図１０にベース体１の変形例を示す。そこでは、ベース体１の締結壁３を壁端縁へ向かって上り傾斜させて、締結壁３と脚壁４との屈曲部３ａが折版屋根材１０の山部分１１で受け止められるようにした。この場合の締結金具２５は、押え壁３３の軒先縁および棟縁に連続して、それぞれへ字状の係止片３７を形成し、締結金具２５をはぜ締め構造１３に締結した状態において、ベース体１の締結壁３を係止片３７で押圧固定できるようにした。この固定状態において、押え壁３３は山部分１１から浮き離れており、屈曲部３ａのみが折版屋根材１０の山部分１１を押圧している。   9 and 10 show a modification of the base body 1. There, the fastening wall 3 of the base body 1 is inclined upward toward the edge of the wall so that the bent portion 3a between the fastening wall 3 and the leg wall 4 is received by the mountain portion 11 of the folding plate roofing material 10. . In this case, the fastening bracket 25 is formed in a state where a hook-shaped locking piece 37 is formed continuously from the eaves edge and the ridge edge of the holding wall 33, and the fastening bracket 25 is fastened to the screw fastening structure 13. The fastening wall 3 of the base body 1 can be pressed and fixed by the locking piece 37. In this fixed state, the presser wall 33 floats away from the mountain portion 11, and only the bent portion 3 a presses the mountain portion 11 of the folding roof material 10.
