Screws 360 are screwed into the screw holes 321 and fastened to the frame 210 to prevent lateral displacement of the frame 210 and to ground the frame 210.
　また、図３に示すように、挟持部３３０には、化粧カバー４００が着脱自在に固定されている。化粧カバー４００は、挟持部３３０に嵌合される嵌合部４１０と、この嵌合部４１０に一体に設けられ、外部に露出するカバー部４２０とを備えている。化粧カバー４００は、軒先等に向けて配置され、太陽電池固定装置３００が露出しないように覆うものである。 Moreover, as shown in FIG. 3, the decorative cover 400 is detachably fixed to the clamping part 330. The decorative cover 400 includes a fitting portion 410 fitted to the holding portion 330 and a cover portion 420 provided integrally with the fitting portion 410 and exposed to the outside. The decorative cover 400 is arranged toward the eaves or the like, and covers the solar cell fixing device 300 so as not to be exposed.
　なお、太陽電池固定装置３００は、フレーム２１０の中途部に配置されるだけではなく、図４に示すように、同一挟持部３００に隣接する太陽電池モジュール２００を同時に取り付けることで連結する機能も有している。 Note that the solar cell fixing device 300 is not only arranged in the middle of the frame 210, but also has a function of connecting the solar cell modules 200 adjacent to the same clamping unit 300 by attaching them simultaneously as shown in FIG. is doing.
　アスファルトシングル１００には、段差部Ｄには必要に応じてスペーサ１３０が積層配置され、平板部３１０とアスファルトシングル１００の上面との間に隙間が生じない。スペーサ１３０は、厚さ３ｍｍのものを１～３枚組み合わせるか、厚さ３ｍｍ及び６ｍｍのものを組み合わせて用いる。 In the asphalt single 100, a spacer 130 is laminated on the step portion D as necessary, and no gap is generated between the flat plate portion 310 and the upper surface of the asphalt single 100. As the spacer 130, one to three spacers having a thickness of 3 mm are combined, or ones having a thickness of 3 mm and 6 mm are combined.
　このように構成された太陽電池固定装置３００を用いて、次のようにしてアスファルトシングル１００上に太陽電池モジュール２００を取り付ける。すなわち、スペーサ１３０で高さ位置を調整し、アスファルトシングル１００を平坦にした上で平板部３１０をアスファルトシングル１００に載置し、ボルト３５０をボルト孔３１１から屋根下地材に向けてねじ込む。 Using the thus configured solar cell fixing device 300, the solar cell module 200 is mounted on the asphalt single 100 as follows. That is, the height position is adjusted by the spacer 130, the asphalt single 100 is flattened, the flat plate portion 310 is placed on the asphalt single 100, and the bolt 350 is screwed from the bolt hole 311 toward the roof base material.
　次に、太陽電池モジュール２００を太陽電池固定部材３００の挟持部３３０にスライドして取り付ける。このとき、適宜、ビス孔３２１にビス３６０をねじ込み、太陽電池モジュール２００を固定する。この作業を繰り返すことで、太陽電池モジュール２００をアスファルトシングル１００に設置することができる。 Next, the solar cell module 200 is slid and attached to the clamping portion 330 of the solar cell fixing member 300. At this time, the screw 360 is appropriately screwed into the screw hole 321 to fix the solar cell module 200. The solar cell module 200 can be installed in the asphalt single 100 by repeating this operation.
　また、この際、太陽電池モジュール２００に接続されるケーブル２３０は、ケーブル収納部３１２，３１３に収納する。 At this time, the cable 230 connected to the solar cell module 200 is stored in the cable storage units 312 and 313.
　上述したように、本実施の形態にかかる太陽電池固定装置３００では、アスファルトシングル１００上に固定する部材と、太陽電池モジュール２００を支持する部材とが一体化されているため、部品コストを低減することができる。また、アスファルトシングル１００に固定する作業と、太陽電池モジュール２００を固定する作業を同時にできるため、作業が簡単化し、設置コストを低減することができる。 As described above, in the solar cell fixing device 300 according to the present embodiment, the member fixed on the asphalt single 100 and the member supporting the solar cell module 200 are integrated, thereby reducing the component cost. be able to. Moreover, since the operation | work which fixes to the asphalt single 100 and the operation | work which fixes the solar cell module 200 can be performed simultaneously, an operation | work can be simplified and installation cost can be reduced.
　また、太陽電池固定装置３００は、太陽電池モジュール２００のフレーム２１０に沿って、スライド移動できるため、アスファルトシングル１００を支持するトラス等の屋根下地材に直接固定することができ、取付強度を増すことができる。したがって、ボルトやビスの本数を減らすことができる。また、太陽電池固定装置３００の平板部３１０のスライド方向の長さはフレーム２１０に比べて短いので、取付強度を増したい場合には、容易に増やすことができる。 In addition, since the solar cell fixing device 300 can slide along the frame 210 of the solar cell module 200, it can be directly fixed to a roof base material such as a truss that supports the asphalt single 100, thereby increasing the mounting strength. Can do. Therefore, the number of bolts and screws can be reduced. Moreover, since the length of the flat plate part 310 of the solar cell fixing device 300 in the sliding direction is shorter than that of the frame 210, it can be easily increased when it is desired to increase the mounting strength.
　さらに、ケーブル収納部３１２，３１３が設けられているため、追加部品を用いることなく、ケーブル２３０を固定することができるため、部品点数を減らすことができる。 Furthermore, since the cable storage portions 312 and 313 are provided, the cable 230 can be fixed without using additional components, so that the number of components can be reduced.
　また、スペーサ１３０を太陽電池固定装置３００の下面に設置することで、隣接する太陽電池モジュール２００の間に配置することで、太陽電池モジュール２００の間の段差調整を行うことができる。 In addition, by installing the spacer 130 on the lower surface of the solar cell fixing device 300, the step difference between the solar cell modules 200 can be adjusted by arranging the spacer 130 between the adjacent solar cell modules 200.
　なお、本発明は前記実施の形態に限定されるものではなく、本発明の要旨を逸脱しない範囲で種々変形実施可能であるのは勿論である。例えば、上述した例では、屋根材としてアスファルトシングルを用いたが、平坦な屋根面を有する屋根材であれば、スペーサ１３０は不要となり、さらに設置が容易となる。 It should be noted that the present invention is not limited to the embodiment described above, and various modifications can be made without departing from the scope of the present invention. For example, in the above-described example, asphalt single is used as the roofing material. However, if the roofing material has a flat roof surface, the spacer 130 becomes unnecessary and the installation becomes easier.
　本発明によれば、太陽電池モジュールの屋根材上の取り付ける際の部品コスト及び設置コストの低減化を図ることができる。 According to the present invention, it is possible to reduce the component cost and the installation cost when the solar cell module is mounted on the roof material.
