Reference numeral 1 denotes an outdoor structure in which the solar cell module 2 is installed on the roof 13, and the solar cell module 2 is attached to the outdoor structure 1. A plurality of long flat ribs 3 fixed in the depth direction on the purlin 14 and nuts 51 are fastened to bolts 5 which are erected by inserting bolt heads into the C-shaped grooves 32 of the flat ribs 3. 3 is provided with a C-shaped presser frame 4 having an elongated cross-section that is fixed orthogonally on the upper side, and an upward L-shaped fixing piece 21 that projects from the end of the solar cell module 2 in the width direction is covered by the C-shaped presser frame 4. The L-shaped fixing piece 21 is sandwiched between the C-shaped presser frame 4 and the flat rib 3 by fitting.

本例にあって屋外構築物１は、例えば、自転車、オートバイ等二輪車用の充電ステーションとしてあり、太陽電池モジュールにより発電し、コントロールボックス１７における図示省略の制御機器、バッテリーを介して、充電ボックス１８の図示省略の充電器に電力を供給し、該充電器によって二輪車のバッテリーに充電を行うようにしてあり、このとき該屋外構築物１は、例えば既存のカーポートの、一対の支柱１１から傾斜突出した梁１２に屋根１３を載置固定したものを用い、該屋根１３に太陽電池モジュール２を設置することによって構成したものとしてある。本例の屋根１３は、例えば幅（横幅）を３ｍ程度、突出長さ（奥行）を２ｍ程度として、梁１２の傾斜に応じて自由端を上位の棟側とし、支柱１１側を下位の軒側とするように、例えば１０°の角度に傾斜した傾斜屋根としてあり、該屋根１３には、例えば横幅を１ｍ弱程度、長さを１．５ｍ弱とした太陽電池モジュール２を、幅方向に３枚設置して、上記充電用の発電を行うようにしてある。   In this example, the outdoor structure 1 is, for example, a charging station for a motorcycle such as a bicycle or a motorcycle. The outdoor structure 1 generates power by a solar cell module and is connected to the charging box 18 via a control device and a battery (not shown) in the control box 17. Electric power is supplied to a charger (not shown), and the battery of the motorcycle is charged by the charger. At this time, the outdoor structure 1 protrudes from a pair of struts 11 of an existing carport, for example. The roof 12 is mounted and fixed on the beam 12, and the solar cell module 2 is installed on the roof 13. The roof 13 of this example has, for example, a width (width) of about 3 m, a protruding length (depth) of about 2 m, the free end as the upper ridge side according to the inclination of the beam 12, and the column 11 side as the lower eave The solar cell module 2 having a lateral width of about 1 m and a length of about 1.5 m is arranged in the width direction on the roof 13. Three are installed to generate the power for charging.

太陽電池モジュール２は、その幅方向端部にそれぞれ上向きのＬ字固定片２１を備えてあり、該Ｌ字固定片２１は、例えば、太陽電池モジュール２に配置したアルミ製のフレームに該フレーム下端から側方に底板を突出し、該底板の先端から起立片を上向きに突出した該フレームに一体のものとしてある。   The solar cell module 2 is provided with an upward L-shaped fixing piece 21 at each end in the width direction. The L-shaped fixing piece 21 is, for example, an aluminum frame disposed in the solar cell module 2 on the lower end of the frame. The bottom plate protrudes laterally from the frame, and the upright piece protrudes upward from the tip of the bottom plate.

平リブ３は、幅広基板３１と、該幅広基板３１の中央位置に配置したボルト頭をスライド自在に嵌挿するＣ字溝３２を備えた、アルミ製長尺一体のものとしてあり、本例にあって該平リブ３は、幅を５ｃｍ程度、Ｃ字溝３２を含めた高さを１ｃｍ程度、長さを屋根幅の略全長に亘るように３ｍ弱としてある。   The flat rib 3 has a long substrate made of aluminum and includes a wide substrate 31 and a C-shaped groove 32 into which a bolt head arranged at the center of the wide substrate 31 is slidably inserted. The flat rib 3 has a width of about 5 cm, a height including the C-shaped groove 32 of about 1 cm, and a length of a little less than 3 m so as to cover the entire length of the roof width.

平リブ３は複数、例えば２本用いて、屋根１３の母屋１４上に固定してあり、本例にあって該固定は、これを、母屋１４に対して平リブ３の幅広基板３１を直接ネジ固定することによって行なってある。   A plurality of, for example, two flat ribs 3 are used and fixed on the purlin 14 of the roof 13. In this example, the fixing is performed by directly attaching the wide substrate 31 of the flat rib 3 to the purlin 14. This is done by screw fixing.

即ち、屋根１３は、屋根構造材として母屋１４を備えているから、平リブ３は、これを該屋根構造材をなす母屋１４に対して重合する如くに固定することによって屋根１３の上下２箇所に幅方向に向けて平行に配置してある。   That is, since the roof 13 includes the main building 14 as the roof structure material, the flat rib 3 is fixed to the main building 14 forming the roof structure material so as to be superposed on the roof 13 at two positions above and below the roof 13. Are arranged in parallel in the width direction.

本例にあって、上記母屋１４に対する直接固定は、該母屋１４に載置固定した屋根材固定枠１５によって葺設した屋根材１６を介して、母屋１４に対してネジを螺入することによって行ってあり、該屋根材１６に上記平リブ３の上記幅広基板３１を載置し、所定間隔で該幅広基板３１からのネジを、これら屋根材１６及び屋根材固定枠１５を貫通して母屋１４に螺入することによって、該平リブ３を母屋１４に対して重合する如くにその直接の固定を行ってある。   In this example, the direct fixing to the main building 14 is performed by screwing a screw into the main building 14 through the roof material 16 installed by the roof material fixing frame 15 placed and fixed on the main building 14. The wide substrate 31 of the flat rib 3 is placed on the roof material 16, and screws from the wide substrate 31 are passed through the roof material 16 and the roof material fixing frame 15 at a predetermined interval. The flat rib 3 is directly fixed so as to be superposed on the main building 14 by being screwed into the base 14.

Ｃ字押え枠４は、例えば２〜３ｃｍの基板と、該基板の両端に太陽電池モジュールの高さ、例えば３．５ｃｍより低い、同じく２〜３ｃｍ程度の垂下片を下向きに突出した断面Ｃ字状にして、太陽電池モジュール２の端部長さを同等の１．５ｍ弱の長さを有する、同じくアルミ製一体長尺のものとしてあり、基板の長手方向に適宜間隔のボルト貫通孔を複数透設したものとしてあり、本例にあって該Ｃ字押え枠４は、太陽電池モジュール２の間に２本、端部に２本の合計４本を用いるものとしてある。   The C-shaped presser frame 4 has a C-shaped cross-section in which, for example, a substrate having a length of 2 to 3 cm and a solar cell module height on the both ends of the substrate, for example, lower than 3.5 cm, and a hanging piece of about 2 to 3 cm are projected downward The end length of the solar cell module 2 has an equivalent length of less than 1.5 m, and is also made of a single long aluminum body, and a plurality of bolt through holes that are appropriately spaced in the longitudinal direction of the substrate. In this example, a total of four C-shaped presser frames 4 are used between the solar cell modules 2 and two at the end.

上記２本の平リブ３及び４本のＣ字押え枠４による太陽電池モジュール２の取付けは、Ｃ字押え枠４によって上記太陽電池モジュール２の隣接する一対のＬ字固定片２１又は端部にあっては該端部片側のＬ字固定片２１を被嵌するとともに平リブ３に起立してＣ字押え枠４のボルト貫通孔を貫通したボルト５に、該Ｃ字押え枠４上でナット５１を締着して、上記Ｌ字固定片２１をＣ字押え枠４で平リブ３に押付け状とすることによって行ってあり、即ち、上記２本の平リブ３に、各固定位置の数、本例にあっては各４本のボルト５を、平リブ３のＣ字溝３２にボルト頭を嵌挿して起立し、該ボルト５のボルト軸を、上記Ｌ字固定片２１を被嵌したＣ字押え枠４のボルト貫通孔を貫通して該Ｃ字押え枠４の基板上に突出し、各ボルト軸にＣ字押え枠４の上面からナット５１を締着し、該ボルトナット６、６１の締着によって、母屋１４上の平リブ３に、Ｌ字固定片２１を被嵌したＣ字押え枠４を一体化して、その太陽電池モジュール２の固定を行ったものとしてある。   The solar cell module 2 is attached by the two flat ribs 3 and the four C-shaped presser frames 4 to the pair of adjacent L-shaped fixing pieces 21 or ends of the solar cell module 2 by the C-shaped presser frame 4. In this case, the L-shaped fixing piece 21 on the end piece side is fitted, and the bolt 5 that stands on the flat rib 3 and penetrates the bolt through hole of the C-shaped presser frame 4 is put on the nut on the C-type presser frame 4. 51 is fastened, and the L-shaped fixing piece 21 is pressed against the flat rib 3 by the C-shaped presser frame 4, that is, the number of each fixed position is set on the two flat ribs 3. In this example, each of the four bolts 5 is erected by inserting a bolt head into the C-shaped groove 32 of the flat rib 3, and the bolt shaft of the bolt 5 is fitted with the L-shaped fixing piece 21. Pierced through the bolt through hole of the C-shaped presser frame 4 and protruded onto the substrate of the C-type presser frame 4, and the C-shaped presser frame 4 The nut 51 is fastened from the upper surface of the frame 4, and the C-shaped presser frame 4 in which the L-shaped fixing piece 21 is fitted is integrated with the flat rib 3 on the purlin 14 by fastening the bolt nuts 6 and 61. The solar cell module 2 is fixed.

即ち、該ボルトナット６、６１の締着によって、Ｃ字押え枠４の垂下片が、平リブ３上に載置したＬ字固定片２１の底板をその上面に圧接して、該垂下片によるＬ字固定片２１の抜止め状態で、該Ｌ字固定片２１を平リブ３とＣ字押え枠４間に一体化するように挟持する結果、太陽電池モジュール２は、その幅方向端部の複数箇所で屋根１３に対して強固に固定されるに至るとともに屋根面と太陽電池モジュール２間には上記平リブ３の高さに応じた空隙が生じるところ、本例の平リブ３の高さは１ｃｍ程度の狭小空隙であるから、太陽電池モジュール２は、該１ｃｍ程度の狭小空隙を介して屋根面に近接した状態で固定されるに至る。   That is, when the bolts and nuts 61 and 61 are fastened, the hanging piece of the C-shaped presser frame 4 presses the bottom plate of the L-shaped fixing piece 21 placed on the flat rib 3 against the upper surface thereof, and the hanging piece As a result of sandwiching the L-shaped fixing piece 21 so as to be integrated between the flat rib 3 and the C-shaped presser frame 4 in a state where the L-shaped fixing piece 21 is not pulled out, the solar cell module 2 has an end portion in the width direction. Along with being firmly fixed to the roof 13 at a plurality of locations, a gap corresponding to the height of the flat rib 3 is formed between the roof surface and the solar cell module 2. Is a narrow gap of about 1 cm, the solar cell module 2 is fixed in the state of being close to the roof surface through the narrow gap of about 1 cm.

このとき、上記太陽電池モジュール２の軒側又は棟側端部に端部枠乃至端部パネル、本例にあっては端部パネル６を設置して、屋根１３と太陽電池モジュール２間の空隙を閉鎖したものとしてある。即ち、本例にあって、幅を３ｍ程度、突出長さを２ｍ程度とした屋根１３に横幅を１ｍ弱程度、長さを１．５ｍ弱とした太陽電池モジュール２を幅方向に３枚設置し、このとき図示されるように屋根突出長さ方向先端に合せて棟側に該３枚の太陽電池モジュールを引寄せ状に配置したから、屋根１３幅方向はこれら太陽電池モジュール２が覆う一方、屋根突出長さ方向の支柱１側、即ち軒側端部に０．５ｍ程度のスペースが生じるところ、本例にあっては該スペースを埋めるように上記端部パネル６を設置してある。   At this time, an end frame or an end panel, in this example, an end panel 6 is installed at the eaves side or ridge side end of the solar cell module 2, and the gap between the roof 13 and the solar cell module 2 is installed. Is closed. That is, in this example, three solar cell modules 2 having a width of about 1 m and a length of about 1.5 m are installed in the width direction on the roof 13 having a width of about 3 m and a protruding length of about 2 m. At this time, as shown in the figure, the three solar cell modules are arranged close to each other on the ridge side in accordance with the front end of the roof protrusion length direction. When a space of about 0.5 m is generated at the support 1 side in the roof protruding length direction, that is, at the eaves side end, in this example, the end panel 6 is installed so as to fill the space.

本例の端部パネル６は、例えば屋根面、本例にあっては屋根材１６に上記平リブ３と平行に断面Ｃ字状の下地材６１をネジ固定し、該下地材６１に上記スペースを覆う幅を有する端部パネル６、例えばアルミパネルを太陽電池モジュール２の軒側に近接するように載置し、該端部パネル６側からの所定間隔のネジで該端部パネル６を下地材６１に固定することによって、該スペースを被覆してあり、これによって屋根１３と太陽電池モジュール２間に生じる上記１ｃｍ程度の上記狭小空隙を閉鎖し、屋根面との間に空隙が開口して残存するのを防止してある。   The end panel 6 of this example is, for example, a roof surface, in this example, a base material 61 having a C-shaped cross section is screwed to the roof material 16 in parallel with the flat rib 3, and An end panel 6, such as an aluminum panel, having a width that covers the surface of the solar cell module 2 is placed close to the eaves side of the solar cell module 2, and the end panel 6 is grounded with screws at a predetermined interval from the end panel 6 side. The space is covered by fixing to the material 61, thereby closing the narrow gap of about 1 cm generated between the roof 13 and the solar cell module 2, and opening the gap between the roof surface. It is prevented from remaining.

以上の屋根１３に対する太陽電池モジュール２の取付構造によれば、該取付けに用いる平リブ３のネジ止め、平リブ３上への太陽電池モジュール２の配置、Ｃ字押え枠４の被嵌配置、ボルト５の起立及びナット５１の締着等の、太陽電池モジュール２の設置作業は、これを、全て屋根面上で容易になし得るとともに該太陽電池モジュール２の屋根面への固定も強固且つ確実になし得る上、屋根面と太陽電池モジュール間の空隙は、上記１ｃｍ程度であるから、強風時も該空隙に風が入り込むのを抑制し得るし、仮に入っても空隙が狭小であるから風圧が減衰され、太陽電池モジュール２が煽られて平リブ３のネジに過大な応力が作用することもない。また、本例では上記端部パネル６を配置して、該空隙を閉鎖したことによって更に強風の影響を解消することができ、太陽電池モジュール２の長期に安定した設置状態を維持することができる。   According to the mounting structure of the solar cell module 2 to the roof 13 described above, the flat rib 3 used for the mounting is screwed, the solar cell module 2 is disposed on the flat rib 3, and the C-shaped presser frame 4 is fitted. Installation work of the solar cell module 2 such as standing of the bolt 5 and fastening of the nut 51 can be easily performed on the roof surface, and the solar cell module 2 can be firmly fixed to the roof surface. In addition, since the gap between the roof surface and the solar cell module is about 1 cm as described above, it is possible to suppress the wind from entering the gap even in a strong wind, and the wind pressure is small even if temporarily entered. Is attenuated, and the solar cell module 2 is beaten, and an excessive stress does not act on the screw of the flat rib 3. Further, in this example, the end panel 6 is arranged and the gap is closed, so that the influence of strong wind can be further eliminated, and the solar cell module 2 can be maintained in a stable installation state for a long time. .

図示した例は以上のとおりとしたが、上記平リブの母屋上の固定を、母屋に対して平リブの水平固定片を他の部材を介して間接的にネジ固定するようにすること、上記太陽電池モジュールの軒側又は棟側端部に端部枠を設置し、また、端部パネルを棟側端部に設置して、屋根と太陽電池モジュール間の空隙を閉鎖するようにすること等を含めて、本発明の実施に当って、母屋、平リブ、Ｃ字押え枠、ボルト、Ｌ字固定片、必要に応じて用いる端部枠乃至端部パネル等の各具体的形状、構造、材質、これらの関係、これらに対する付加等は、上記発明の要旨に反しない限り様々な形態のものとすることができる。   Although the illustrated example is as described above, the fixing of the flat rib on the main roof is indirectly fixed to the main roof by screwing the horizontal fixing piece of the flat rib through another member, Install an end frame at the eaves side or ridge side end of the solar cell module, and install an end panel at the ridge side end to close the gap between the roof and the solar cell module, etc. In carrying out the present invention, including the main building, flat rib, C-shaped presser frame, bolt, L-shaped fixed piece, each of the specific shapes and structures, such as the end frame or the end panel used as necessary, The materials, their relationship, addition to these, and the like can be in various forms as long as they do not contradict the gist of the invention.
