Description

太陽電池モジュールの架台、その施工方法、及びそれを備えた太陽光発電システムSolar cell module mount, construction method thereof, and solar power generation system including the same
 本発明は、太陽光を光電変換する太陽電池モジュールの架台、その施工方法、及びそれを備えた太陽光発電システムに関する。 The present invention relates to a stand for a solar cell module that photoelectrically converts sunlight, a method for its construction, and a photovoltaic power generation system including the same.
 この種の太陽光発電システムにおいては、太陽電池モジュールを架台上に固定支持している。例えば、特許文献1では、複数の桟と複数の支持部材を井桁状に組み合わせ、各桟の間に複数の太陽電池モジュールを架け渡して、各太陽電池モジュールを支持している。また、桟上の複数箇所にそれぞれの固定用フックを設け、太陽電池モジュールのフレームの複数箇所に係合凹所を形成し、太陽電池モジュールのフレームの各係合凹所を桟上の各固定用フックに係合させて、太陽電池モジュールを固定している。 In this type of solar power generation system, the solar cell module is fixedly supported on a frame. For example, in Patent Document 1, a plurality of crosspieces and a plurality of support members are combined in a cross beam shape, and a plurality of solar cell modules are bridged between each crosspiece to support each solar cell module. Also, fixing hooks are provided at a plurality of locations on the crosspiece, engagement recesses are formed at a plurality of locations on the solar cell module frame, and each engagement recess of the solar cell module frame is fixed on the crosspiece. The solar cell module is fixed by being engaged with the hook.
 このような架台では、太陽電池モジュール毎に、太陽電池モジュールをその設置位置まで搬送し、太陽電池モジュールを持ち上げて各桟の間に架け渡しているが、太陽電池モジュールが重いため、その搬送や持ち上げの作業が容易ではなく、これが作業効率低下の原因になっていた。 In such a gantry, for each solar cell module, the solar cell module is transported to its installation position, and the solar cell module is lifted and bridged between the bars. The lifting work is not easy, and this causes a reduction in work efficiency.
特開平9-235814号公報JP-A-9-235814
 上述のように従来は、太陽電池モジュールが重いため、太陽電池モジュールをその設置位置まで搬送し、太陽電池モジュールを持ち上げて各桟の間に架け渡すという作業が容易ではなく、これが作業効率低下の原因になっていた。 Conventionally, as described above, since the solar cell module is heavy, it is not easy to transport the solar cell module to its installation position, lift the solar cell module and bridge it between the crosspieces, which reduces work efficiency. It was the cause.
 特許文献1では、太陽電池モジュールを屋根等の狭いスペースに設置し、また各桟の高さが低いので、太陽電池モジュールを搬送したり持ち上げたりする作業が不可能ではない。しかしながら、広い敷地で高い各桟上に多数の太陽電池モジュールを架け渡して設置する場合は、そのような作業の困難性が極めて高くなる。 In Patent Document 1, since the solar cell module is installed in a narrow space such as a roof and the height of each crosspiece is low, it is not impossible to carry or lift the solar cell module. However, when a large number of solar cell modules are installed on each high beam on a large site, the difficulty of such work becomes extremely high.
 そこで、本発明は、上記従来の問題点に鑑みてなされたものであり、太陽電池モジュールの搭載作業が容易な太陽電池モジュールの架台、その施工方法、及びそれを備えた太陽光発電システムを提供することを目的とする。 Therefore, the present invention has been made in view of the above-described conventional problems, and provides a solar cell module mount, a construction method thereof, and a solar power generation system including the same, in which the solar cell module can be easily mounted. The purpose is to do.
 上記課題を解決するために、本発明の太陽電池モジュールの架台は、太陽電池モジュールが載置される桟と、前記太陽電池モジュールが固定される前記桟の固定部位上側に配置された押え部材と、前記桟の固定部位下側で昇降移動できるように設けられた受け部材と、前記桟を介して前記押え部材と前記受け部材を連結する連結部材とを備え、前記桟の固定部位に、前記受け部材の少なくとも一部を前記桟の上方に突出可能とする開口部が形成されていることによって特徴付けられている。 In order to solve the above problems, the solar cell module mount according to the present invention includes a beam on which the solar cell module is placed, and a pressing member disposed on the upper side of the beam on which the solar cell module is fixed. A receiving member provided so as to be able to move up and down below the fixed portion of the crosspiece, and a connecting member that connects the holding member and the receiving member via the crosspiece, It is characterized by an opening that allows at least a part of the receiving member to protrude above the crosspiece.
 このような本発明の太陽電池モジュールの架台では、押え部材を太陽電池モジュールが固定される桟の固定部位上側に配置し、受け部材を桟の固定部位下側で昇降移動出来るように設け、連結部材により押え部材と受け部材を連結している。この連結部材により押え部材と受け部材の間が締め付けられると、押え部材と受け部材との間隔が狭くなり、連結部材により受け部材が持ち上げられ、受け部材の少なくとも一部が桟の固定部位の開口部から桟の上方に突出する。このとき、桟の固定部位では、押え部材と受け部材の間に太陽電池モジュールが挟み込まれて固定される。 In the platform of the solar cell module of the present invention, the holding member is arranged above the fixed portion of the crosspiece to which the solar cell module is fixed, and the receiving member is provided so as to be moved up and down below the fixed portion of the crosspiece. The presser member and the receiving member are connected by the member. When the gap between the presser member and the receiving member is tightened by the connecting member, the interval between the presser member and the receiving member is narrowed, the receiving member is lifted by the connecting member, and at least a part of the receiving member is opened to the fixing portion of the crosspiece. It protrudes above the crosspiece from the section. At this time, in the fixed part of the crosspiece, the solar cell module is sandwiched and fixed between the pressing member and the receiving member.
 ここで、連結部材を締め付ける以前は、押え部材を桟の固定部位上側に配置し、受け部材を桟の固定部位下側で昇降移動出来るように設けていることから、太陽電池モジュールを桟に載せても、太陽電池モジュールが押え部材及び受け部材のいずれにも接することはなく引っ掛かりもせず、太陽電池モジュールを桟上で長い距離スライド移動させることができる。このため、太陽電池モジュールを桟上の設置位置まで容易に移動させることができ、太陽電池モジュールの搭載作業が容易になる。 Here, before tightening the connecting member, the presser member is arranged above the fixed part of the crosspiece and the receiving member is provided so that it can be moved up and down below the fixed part of the crosspiece. However, the solar cell module does not come into contact with any of the pressing member and the receiving member and is not caught, and the solar cell module can be slid on the bar for a long distance. For this reason, a solar cell module can be easily moved to the installation position on a crosspiece, and the mounting operation | work of a solar cell module becomes easy.
 また、本発明の太陽電池モジュールの架台においては、前記太陽電池モジュールに接触する前記押え部材の部位及び前記受け部材の部位に、それぞれ弾性部材を設けてもよい。 Moreover, in the mount for the solar cell module of the present invention, an elastic member may be provided at each of the holding member and the receiving member that are in contact with the solar cell module.
 この構成の場合は、押え部材の弾性部材と受け部材の弾性部材との間に太陽電池モジュールが挟み込まれて支持されるので、太陽電池モジュールの破損等を効果的に防止することができる。 In this configuration, since the solar cell module is sandwiched and supported between the elastic member of the holding member and the elastic member of the receiving member, damage to the solar cell module can be effectively prevented.
 更に、本発明の太陽電池モジュールの架台においては、前記押え部材の弾性部材の下面と前記開口部周囲の前記桟の上面との間の間隔が前記太陽電池モジュールの厚み以上となる状態で、前記押え部材を保持可能とする構成であってもよい。 Furthermore, in the mount of the solar cell module of the present invention, in a state where the distance between the lower surface of the elastic member of the pressing member and the upper surface of the bar around the opening is equal to or greater than the thickness of the solar cell module, The structure which can hold | maintain a pressing member may be sufficient.
 この構成の場合は、連結部材を締め付ける以前は、押え部材の弾性部材の下面と開口部周囲の桟の上面との間の間隔が太陽電池モジュールの厚み以上となる。このため、太陽電池モジュールを桟に載せても、太陽電池モジュールが押え部材の弾性部材に接することはなく引っ掛かりもせず、太陽電池モジュールを桟上でスライド移動させることができる。 In this configuration, before the connecting member is tightened, the distance between the lower surface of the elastic member of the pressing member and the upper surface of the crosspiece around the opening is equal to or greater than the thickness of the solar cell module. For this reason, even if a solar cell module is mounted on a crosspiece, a solar cell module does not touch the elastic member of a pressing member, and does not get caught, and a solar cell module can be slid on the crosspiece.
 また、本発明の太陽電池モジュールの架台においては、前記連結部材は、前記押え部材と前記受け部材の間を締め付けるネジ部材であり、前記ネジ部材は、前記押え部材に対して回転可能に係合し、前記受け部材に螺合する構成であってもよい。 Moreover, in the mount of the solar cell module of this invention, the said connection member is a screw member which clamps between the said pressing member and the said receiving member, and the said screw member is engaged with the said pressing member so that rotation is possible. And the structure screwed to the said receiving member may be sufficient.
 この構成では、連結部材の回転により押え部材と受け部材の間が締め付けられる。 In this configuration, the presser member and the receiving member are tightened by the rotation of the connecting member.
 更に、本発明の太陽電池モジュールの架台においては、前記受け部材は、前記桟に引っ掛かって、該受け部材の下降を制限するストッパーを有していてもよい。 Furthermore, in the mount of the solar cell module of the present invention, the receiving member may have a stopper that is hooked on the bar and restricts the descending of the receiving member.
 この構成の場合は、受け部材が桟に引っ掛かって支持され、連結部材が受け部材にねじ込まれて突設されるので、受け部材に対する連結部材のねじ込み量により連結部材に係合する押え部材の高さ位置を調節することができる。 In this configuration, since the receiving member is hooked and supported by the crosspiece and the connecting member is screwed into the receiving member and protruded, the height of the presser member that engages the connecting member by the amount of screwing of the connecting member with respect to the receiving member is increased. The position can be adjusted.
 また、本発明の太陽電池モジュールの架台においては、前記桟は、該桟の長手方向に沿って形成され、前記太陽電池モジュールを載置する載置板と、該桟の長手方向に沿って形成され、前記太陽電池モジュールを案内する案内レールとを備えていてもよい。 Moreover, in the mount for the solar cell module of the present invention, the crosspiece is formed along the longitudinal direction of the crosspiece, and is formed along the longitudinal direction of the crosspiece, the mounting plate on which the solar cell module is placed. And a guide rail for guiding the solar cell module.
 この構成の場合は、太陽電池モジュールが載置板上でスライドし、太陽電池モジュールが案内レールにより案内される。 In the case of this configuration, the solar cell module slides on the mounting plate, and the solar cell module is guided by the guide rail.
 更に、本発明の太陽電池モジュールの架台においては、前記案内レールは、前記載置板よりも高く突出し、前記押え部材は、前記案内レールに当接して前記桟の固定部位上側で位置決めされることが好ましい。 Furthermore, in the mount of the solar cell module of the present invention, the guide rail protrudes higher than the mounting plate, and the presser member is in contact with the guide rail and positioned above the fixed portion of the crosspiece. Is preferred.
 この構成により、押え部材を桟の固定部位上側で位置決めすることができる。 This configuration allows the presser member to be positioned above the fixed part of the crosspiece.
 一方、本発明の施工方法は、上記本発明の太陽電池モジュールの架台の施工方法であって、前記桟の固定部位下側に前記受け部材を下降させた状態で、前記太陽電池モジュールを前記桟に載せてスライドさせ、前記受け部材の少なくとも一部を前記桟の固定部位に形成された開口部を通じて該桟の上方に突出させ、前記押え部材と前記受け部材の間に前記太陽電池モジュールを挟持することによって特徴付けられている。 On the other hand, the construction method of the present invention is a method of constructing the solar cell module frame of the present invention, wherein the solar cell module is mounted on the rail in a state where the receiving member is lowered below the fixed portion of the rail. The solar cell module is sandwiched between the holding member and the receiving member by causing at least a part of the receiving member to protrude above the crossing through an opening formed in a fixing portion of the crossing. It is characterized by
 この施工方法により、桟の固定部位下側に受け部材を下降させた状態では、太陽電池モジュールを桟に載せても、太陽電池モジュールが受け部材に接することはなく引っ掛かりもせず、太陽電池モジュールを桟上で長い距離スライド移動させることができる。このため、太陽電池モジュールを桟上の設置位置まで容易に移動させることができ、地上での太陽電池モジュールの搬送作業を簡略化することができる。この後に、連結部材を締め付ければ、押え部材と受け部材の間に太陽電池モジュールを挟み込んで固定することができる。 With this construction method, in a state where the receiving member is lowered below the fixed part of the crosspiece, even if the solar cell module is placed on the crosspiece, the solar cell module does not touch the receiving member and does not get caught. It can be moved for a long distance on the pier. For this reason, a solar cell module can be easily moved to the installation position on a crosspiece, and the conveyance work of the solar cell module on the ground can be simplified. After this, if the connecting member is tightened, the solar cell module can be sandwiched and fixed between the pressing member and the receiving member.
 次に、本発明の太陽光発電システムは、上記本発明の太陽電池モジュールの架台を備えていることによって特徴付けられている。 Next, the photovoltaic power generation system of the present invention is characterized by being provided with the mount for the solar cell module of the present invention.
 このような太陽光発電システムにおいても、上記本発明の太陽電池モジュールの架台と同様の作用効果を奏する。 Also in such a solar power generation system, the same operational effects as the above-described solar cell module frame of the present invention are exhibited.
 また、本発明の太陽光発電システムは、太陽電池モジュールと、前記太陽電池モジュールが載置される桟と、前記太陽電池モジュールを上側から押える押え部材と、前記太陽電池モジュールを下側から受ける受け部材と、前記桟を介して前記押え部材と前記受け部材とを連結する連結部材をとを備え、前記桟に設けられた開口部から前記受け部材の少なくとも一部が突出して、前記太陽電池モジュールが前記押え部材と前記受け部材とにより挟持されていることによって特徴付けられている。 The solar power generation system of the present invention includes a solar cell module, a beam on which the solar cell module is placed, a pressing member that presses the solar cell module from the upper side, and a receiver that receives the solar cell module from the lower side. And a connecting member that connects the pressing member and the receiving member via the crosspiece, and at least a part of the receiving member protrudes from an opening provided in the crosspiece, and the solar cell module Is characterized by being sandwiched between the pressing member and the receiving member.
 このような本発明の太陽光発電システムでは、押え部材を上側に配置し、受け部材を下側に配置していることから、太陽電池モジュールを押え部材及び受け部材のいずれにも引っ掛けずに、太陽電池モジュールを桟上で長い距離スライド移動させることができる。このため、太陽電池モジュールを桟上の設置位置まで容易に移動させることができ、太陽電池モジュールの搭載作業が容易になる。 In such a photovoltaic power generation system of the present invention, the pressing member is arranged on the upper side and the receiving member is arranged on the lower side, so that the solar cell module is not hooked on either the pressing member or the receiving member. The solar cell module can be slid on the bar for a long distance. For this reason, a solar cell module can be easily moved to the installation position on a crosspiece, and the mounting operation | work of a solar cell module becomes easy.
 また、本発明の太陽光発電システムにおいては、前記太陽電池モジュールを挟持する部位において、前記押え部材と前記受け部材とのそれぞれに弾性部材が設けられており、前記受け部材の弾性部材が前記桟の開口部を通じて該桟の上方に突出して、前記押え部材の弾性部材と前記受け部材の弾性部材との間に前記太陽電池モジュールが挟み込まれていることが好ましい。 Further, in the photovoltaic power generation system of the present invention, an elastic member is provided on each of the pressing member and the receiving member at a portion where the solar cell module is sandwiched, and the elastic member of the receiving member is the crosspiece. It is preferable that the solar cell module is sandwiched between the elastic member of the pressing member and the elastic member of the receiving member so as to protrude above the crosspiece through the opening.
 この構成の場合は、押え部材の弾性部材と受け部材の弾性部材との間に太陽電池モジュールが挟み込まれて支持されるので、太陽電池モジュールの破損等を効果的に防止することができる。 In this configuration, since the solar cell module is sandwiched and supported between the elastic member of the holding member and the elastic member of the receiving member, damage to the solar cell module can be effectively prevented.
 更に、本発明の太陽光発電システムにおいては、前記太陽電池モジュールの長い方の2辺端部が、平行に配置された2本の前記桟に載せられて支持されていてもよい。 Furthermore, in the photovoltaic power generation system of the present invention, the longer two side ends of the solar cell module may be placed on and supported by the two bars arranged in parallel.
 この場合は、太陽電池モジュールの長い方の対向2辺端部が2本の平行な桟上に載せられ、太陽電池モジュールの短い方の対向2辺の方向で、太陽電池モジュールが各桟間に架け渡される。太陽電池モジュールの長い方の対向2辺の方向での撓み量が短い方の対向2辺の方向での撓み量よりも大きいことから、長い方の対向2辺の方向よりも短い方の対向2辺の方向で、太陽電池モジュールを各桟間に架け渡した方が強度的に優れる。これにより、太陽電池モジュールの補強部材を簡略化して、部品点数を削減し、コストを低減することができる。 In this case, the two opposite ends of the long side of the solar cell module are placed on two parallel bars, and the solar cell module is positioned between the two bars in the direction of the two opposite sides of the solar cell module. It is bridged. Since the amount of bending in the direction of the two opposite opposing sides of the solar cell module is larger than the amount of bending in the direction of the two opposing opposing sides, the opposing two of the shorter one than the direction of the two opposing opposing sides. In the direction of the side, it is better in strength to span the solar cell module between the crosspieces. Thereby, the reinforcing member of the solar cell module can be simplified, the number of parts can be reduced, and the cost can be reduced.
 また、本発明の太陽光発電システムにおいては、前記太陽電池モジュールの短い方の2辺端部の少なくとも一方に保護部材を付設することが好ましい。 Moreover, in the solar power generation system of the present invention, it is preferable to attach a protective member to at least one of the two shorter side edges of the solar cell module.
 各太陽電池モジュールの短い方の対向2辺が隣り合うように各太陽電池モジュールを並設したときに、各太陽電池モジュールの短い方の対向2辺端部が直接接触するため、太陽電池モジュールの短い方の対向2辺端部にそれぞれの保護部材を付設して、各太陽電池モジュール間に各保護部材が挟み込まれるようにしている。 When the solar cell modules are arranged side by side so that the two opposite sides of each solar cell module are adjacent to each other, the ends of the two opposite sides of each solar cell module are in direct contact with each other. Each protection member is attached to the shorter two opposite side edges so that each protection member is sandwiched between the solar cell modules.
 更に、本発明の太陽光発電システムにおいては、前記太陽電池モジュールは、透光性基板と、前記透光性基板上に形成された光電変換層と、光電変換層側に配置された保護板とを備え、前記太陽電池モジュールは、外周部にフレームが設けられていないフレームレスタイプであることが好ましい。 Furthermore, in the solar power generation system of the present invention, the solar cell module includes a translucent substrate, a photoelectric conversion layer formed on the translucent substrate, and a protective plate disposed on the photoelectric conversion layer side. The solar cell module is preferably a frameless type in which a frame is not provided on the outer periphery.
 このようなフレームレスタイプの太陽電池モジュールは、太陽電池モジュールの各端部全体を保護するための矩形状の金属フレームを備えず、構造が簡単であるという利点がある。 Such a frameless type solar cell module is advantageous in that it does not include a rectangular metal frame for protecting the entire ends of the solar cell module and is simple in structure.
 本発明の太陽電池モジュールの架台によれば、桟の固定部位上側に配置された押え部材と、桟の固定部位下側で昇降移動できるように設けられた受け部材と、桟を介して押え部材と受け部材を連結する連結部材とを備え、受け部材の少なくとも一部を桟の上方に突出可能とする開口部が形成されているので、太陽電池モジュールの設置時に押え部材及び受け部材が設置作業に大きな支障を及ぼすことがなく、太陽電池モジュールの搭載作業が容易になる。 According to the mount of the solar cell module of the present invention, the holding member disposed above the fixed portion of the crosspiece, the receiving member provided so as to be moved up and down below the fixed portion of the crosspiece, and the presser member via the crosspiece And a connecting member for connecting the receiving member, and an opening that allows at least a part of the receiving member to protrude above the crosspiece is formed, so that the pressing member and the receiving member are installed when the solar cell module is installed. The solar cell module can be easily mounted without causing any major trouble.
 本発明の太陽電池モジュールの施工方法によれば、桟の固定部位下側に受け部材を下降させた状態で、太陽電池モジュールを桟に載せてスライドさせ、受け部材の少なくとも一部を桟の開口部を通じて上方に突出させ、押え部材と受け部材の間に太陽電池モジュールを挟持するので、太陽電池モジュールを桟上で容易にスライド移動させることができ、太陽電池モジュールの搭載作業が容易になる。 According to the solar cell module construction method of the present invention, in a state where the receiving member is lowered below the fixed portion of the crosspiece, the solar cell module is placed on the crosspiece and slid, and at least a part of the receiving member is opened in the crosspiece. Since the solar cell module is protruded upward through the portion and the solar cell module is sandwiched between the pressing member and the receiving member, the solar cell module can be easily slid on the rail, and the mounting operation of the solar cell module becomes easy.
 本発明の太陽光発電システムによれば、太陽電池モジュールを上側から押える押え部材と、太陽電池モジュールを下側から受ける受け部材と、桟を介して押え部材と受け部材を連結する連結部材とを備え、桟に設けられた開口部から受け部材の少なくとも一部が突出して、太陽電池モジュールが押え部材と受け部材とにより挟持されているので、太陽電池モジュールの設置時に押え部材及び受け部材が設置作業に大きな支障を及ぼすことがなく、太陽電池モジュールの搭載作業が容易になる。 According to the photovoltaic power generation system of the present invention, the pressing member that presses the solar cell module from the upper side, the receiving member that receives the solar cell module from the lower side, and the connecting member that connects the pressing member and the receiving member via the crosspiece.

 以下、本発明の実施形態を添付図面を参照しつつ詳細に説明する。 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
 図1は、本発明の太陽電池モジュールの架台の一実施形態を適用した太陽光発電システムを示す斜視図である。この太陽光発電システムは、発電所としての適用を前提としたものであり、多数の太陽電池モジュールを備えている。 FIG. 1 is a perspective view showing a solar power generation system to which an embodiment of a solar cell module mount of the present invention is applied. This solar power generation system is premised on application as a power plant, and includes a large number of solar cell modules.
 図1に示すように太陽光発電システムでは、複数の支柱11を等間隔に配して地面に垂直に突設し、各支柱11の上端部にそれぞれの縦桟12の中央部を接続して、各縦桟12を傾斜させて固定し、4本の横桟13を各縦桟12と直交するように配して、各横桟13を各縦桟12上に平行に並べかつ相互に異なる高さに配置し、各横桟13間に複数の太陽電池モジュール16を架け渡して傾斜させ、各横桟13に設けられた複数組の押え金具14と受け金具(図示せず)により各太陽電池モジュール16の両端部を固定支持している。 As shown in FIG. 1, in the photovoltaic power generation system, a plurality of support columns 11 are arranged at regular intervals so as to protrude perpendicularly to the ground, and the central portion of each vertical beam 12 is connected to the upper end of each support column 11. The vertical bars 12 are inclined and fixed, the four horizontal bars 13 are arranged so as to be orthogonal to the vertical bars 12, and the horizontal bars 13 are arranged in parallel on the vertical bars 12 and are different from each other. A plurality of solar cell modules 16 are placed between the horizontal rails 13 so as to be inclined, and each of the suns is formed by a plurality of presser fittings 14 and receiving brackets (not shown) provided on the horizontal rails 13. Both ends of the battery module 16 are fixedly supported.
 また、各横桟13と直交する複数の補助桟15を配して、各補助桟15を各横桟13の底面に固定し、各横桟13と各補助桟15を井桁状に組み合わせている。後で述べるように各横桟13と各補助桟15を井桁状に組み合わせた後に、各横桟13を各縦桟12に載せて固定する。 Also, a plurality of auxiliary rails 15 orthogonal to each horizontal beam 13 are arranged, each auxiliary beam 15 is fixed to the bottom surface of each horizontal beam 13, and each horizontal beam 13 and each auxiliary beam 15 are combined in a cross beam shape. . As will be described later, after each horizontal beam 13 and each auxiliary beam 15 are combined in a cross beam shape, each horizontal beam 13 is mounted on each vertical beam 12 and fixed.
 このような構成の太陽光発電システムにおいては、下側から1番目の横桟13と2番目の横桟13の間、2番目の横桟13と3番目の横桟13の間、及び3番目の横桟13と4番目の横桟13の間のいずれにも、複数の太陽電池モジュール16を横一列に並べて搭載している。従って、4本の横桟13上に、複数の太陽電池モジュール16が3列に並べて搭載されている。 In the solar power generation system having such a configuration, the first horizontal beam 13 and the second horizontal beam 13 from the lower side, the second horizontal beam 13 and the third horizontal beam 13, and the third A plurality of solar cell modules 16 are arranged in a horizontal row between each of the horizontal rails 13 and the fourth horizontal rail 13. Therefore, a plurality of solar cell modules 16 are arranged in three rows on the four horizontal rails 13.
 また、太陽電池モジュール16の短い方の対向2辺の方向で、太陽電池モジュール16を各横桟13間に架け渡して、太陽電池モジュール16の長い方の対向2辺端部を各横桟13上に載せている。 Further, the solar cell module 16 is bridged between the horizontal bars 13 in the direction of the two opposite sides of the solar cell module 16, and the opposite two side ends of the longer side of the solar cell module 16 are connected to the horizontal bars 13. It is on top.
 尚、図1において、各支柱11が並ぶ方向をX方向(左右方向)とし、このX方向と直交する方向をY方向(前後方向)としている。 In FIG. 1, the direction in which the columns 11 are arranged is the X direction (left-right direction), and the direction orthogonal to the X direction is the Y direction (front-rear direction).
 図2は、太陽電池モジュール16を示す斜視図である。図2に示すように太陽電池モジュール16は、長方形の太陽電池モジュールであって、本実施形態では、短い方の対向2辺端部16bの少なくとも1辺に保護部材21を設けている。 FIG. 2 is a perspective view showing the solar cell module 16. As shown in FIG. 2, the solar cell module 16 is a rectangular solar cell module, and in the present embodiment, a protection member 21 is provided on at least one side of the shorter two opposite side end portions 16 b.
 太陽電池モジュール16は、例えば2枚のガラス板の間に、透明電極膜、光電変換層(半導体層)、及び裏面電極膜を順次積層してなる太陽電池セルを挟み込んで、各ガラス板の端部を封止したものである。この太陽電池モジュール16についてより詳細に説明すれば、透光性基板であるガラス基板に透明電極と、半導体層からなる光電変換層と、裏面電極層とをこの順に積層して、太陽電池セルを形成し、裏面電極層側に保護板である透光性のガラス基板を貼り合わせて、各ガラス基板間を封止した構成である。あるいは、1枚のガラス板と保護層の間に太陽電池セルを挟み込んで封止したものでもよい。 For example, the solar cell module 16 sandwiches a solar cell formed by sequentially laminating a transparent electrode film, a photoelectric conversion layer (semiconductor layer), and a back electrode film between two glass plates, and the end of each glass plate is sandwiched between them. It is sealed. The solar cell module 16 will be described in more detail. A transparent electrode, a photoelectric conversion layer composed of a semiconductor layer, and a back electrode layer are laminated in this order on a glass substrate that is a light-transmitting substrate, and a solar cell is formed. The transparent glass substrate which is a protective plate is bonded to the back electrode layer side, and the space between the glass substrates is sealed. Alternatively, a solar battery cell sandwiched between one glass plate and a protective layer may be sealed.
 このような太陽電池モジュール16は、その端部を保護するための矩形状の金属フレームを備えず、透光性基板と保護板の周縁端部が露出した形態のいわゆるフレームスタイプの薄膜太陽電池モジュールと称されるものである。 Such a solar cell module 16 does not include a rectangular metal frame for protecting the end portion thereof, and is a so-called frames-type thin film solar cell in which the peripheral end portions of the translucent substrate and the protective plate are exposed. It is called a module.
 保護部材21は、U字型の断面形状を有する弾性部材(例えばゴム材)のみからなり、保護部材21の内側の溝に太陽電池モジュール16の端部16bが嵌め入れられて、保護部材21が太陽電池モジュール16の端部16bに取付けられている。この保護部材21は、図1に示すように横一列に配列された各太陽電池モジュール16の端部16b間に挟み込まれて、各太陽電池モジュール16の端部16b同士の直接接触を防止する。 The protective member 21 is composed only of an elastic member (for example, a rubber material) having a U-shaped cross-sectional shape, and the end portion 16b of the solar cell module 16 is fitted into the groove inside the protective member 21, so that the protective member 21 is The solar cell module 16 is attached to the end 16b. As shown in FIG. 1, the protection member 21 is sandwiched between the end portions 16 b of the solar cell modules 16 arranged in a horizontal row to prevent direct contact between the end portions 16 b of the solar cell modules 16.
 保護部材21の材質としては、耐衝撃性の観点からは弾性部材を用いることが好ましく、また太陽電池モジュール16外周端面での電気的絶縁性の観点からは絶縁性部材を用いることが好ましく、これらの理由からゴム材を用いている。 As the material of the protective member 21, it is preferable to use an elastic member from the viewpoint of impact resistance, and it is preferable to use an insulating member from the viewpoint of electrical insulation at the outer peripheral end face of the solar cell module 16. For this reason, rubber is used.
 尚、太陽光発電システムの施工方法によっては、横一列に配列された各太陽電池モジュール16の端部16bの間隔を空けたり、各太陽電池モジュール16の端部16b同士の接触を緩和させることが可能であり、この場合は、保護部材21を設けなくてもよい。 In addition, depending on the construction method of the solar power generation system, it is possible to increase the spacing between the end portions 16b of the solar cell modules 16 arranged in a horizontal row, or to relax the contact between the end portions 16b of the solar cell modules 16. In this case, the protection member 21 may not be provided.
 図3(a)、(b)は、それぞれ縦桟12を示す斜視図及び断面図である。図3(a)、(b)に示すように縦桟12は、側板12a、及び側板12aの両側で折り曲げられた天板12bと底板12cを有しており、その断面形状が概ねZ字型となっている。側板12aの一端には、上側に突出するストッパー片12dが設けられている。また、4本の横桟13が連結される天板12bのそれぞれの箇所には、長形孔12eが形成されている。更に、側板12aの略中央には、4つの穿孔12fが形成されており、各穿孔12fが縦桟12の長手方向に対して斜め方向の2列に並べて形成されている。 3 (a) and 3 (b) are a perspective view and a cross-sectional view showing the vertical beam 12, respectively. As shown in FIGS. 3A and 3B, the vertical rail 12 has a side plate 12a and a top plate 12b and a bottom plate 12c that are bent on both sides of the side plate 12a, and the cross-sectional shape thereof is generally Z-shaped. It has become. A stopper piece 12d protruding upward is provided at one end of the side plate 12a. Further, a long hole 12e is formed in each portion of the top plate 12b to which the four horizontal rails 13 are connected. Furthermore, four perforations 12f are formed in the approximate center of the side plate 12a, and each perforation 12f is formed in two rows in an oblique direction with respect to the longitudinal direction of the vertical rail 12.
 図4は、縦桟12の側板12aの中央部に重ねられる補強板22を示す斜視図である。図4に示すように補強板22は、矩形状のものであり、縦桟12の側板12aの各穿孔12fに重なるそれぞれの穿孔22aを有している。また、補強板12の4辺が折り曲げられて、その剛性が高められている。 FIG. 4 is a perspective view showing the reinforcing plate 22 superimposed on the central portion of the side plate 12a of the vertical rail 12. As shown in FIG. As shown in FIG. 4, the reinforcing plate 22 has a rectangular shape and has respective perforations 22 a that overlap the respective perforations 12 f of the side plate 12 a of the vertical rail 12. Further, the four sides of the reinforcing plate 12 are bent to increase its rigidity.
 ここで、図1及び図5に示すように支柱11は、相互に対向する一対のフランジ及び各フランジを連結するウェブからなるH字形断面形状の鋼材を適宜の長さに切断してなり、地面に打ち込まれている。この支柱11のフランジの上端部には、4つの長形孔11cが形成されており、ウェブの上端部に縦桟12の側板12aの中央部が重ね合わせられ、縦桟12aの側板12aの中央部に補強板22が重ねられ、ウェブの上端部の各長形孔11c、縦桟12の側板12aの各穿孔12f、及び補強板22の各穿孔22aにそれぞれのボルトが通され、各ボルトにそれぞれのナットがねじ込まれて締め付けられ、支柱11の上端部に縦桟12の中央部が接続固定される。このとき、縦桟12の側板12aの各穿孔12fが縦桟12の長手方向に対して斜め方向の2列に並べて形成されていることから、ウェブの上端部の各長形孔11cと縦桟12の側板12aの中央の各穿孔12fとが重ね合わされると、縦桟12が支柱11に対して傾斜し、この状態で縦桟12が支柱11に固定される。 Here, as shown in FIG.1 and FIG.5, the support | pillar 11 cut | disconnects the steel material of the H-shaped cross section which consists of a pair of mutually opposing flanges and the web which connects each flange to suitable length, Has been driven into. Four elongated holes 11c are formed at the upper end of the flange of the column 11, and the center of the side plate 12a of the vertical beam 12 is overlapped with the upper end of the web, so that the center of the side plate 12a of the vertical beam 12a is overlapped. Reinforcing plates 22 are stacked on the web, and the bolts are passed through the long holes 11c at the upper end of the web, the perforations 12f of the side plates 12a of the vertical rails 12, and the perforations 22a of the reinforcing plates 22, respectively. Each nut is screwed and tightened, and the central portion of the vertical beam 12 is connected and fixed to the upper end portion of the column 11. At this time, since the perforations 12f of the side plate 12a of the vertical beam 12 are formed in two rows obliquely with respect to the longitudinal direction of the vertical beam 12, the long holes 11c at the upper end of the web and the vertical beam are formed. When the perforations 12f at the center of the 12 side plates 12a are overlapped, the vertical beam 12 is inclined with respect to the column 11, and the vertical beam 12 is fixed to the column 11 in this state.
 また、支柱11のウェブの上端部の各長形孔11cが垂直方向に長いことから、各ボルトのナットを緩めれば、縦桟12を上下に移動させて、縦桟12の高さを調節することができる。 Further, since each elongated hole 11c at the upper end of the web of the column 11 is long in the vertical direction, if the nut of each bolt is loosened, the vertical beam 12 is moved up and down to adjust the height of the vertical beam 12 can do.
 図6(a)、(b)は、それぞれ横桟13を示す斜視図及び断面図である。図6(a)、(b)に示すように横桟13は、凸状に突出した案内レール13a、案内レール13aの両側で同一平面上に設けられた各載置板13b、各載置板13bの両側で下方に折り曲げられた各側板13c、及び各側板13cの一辺で内側に折り曲げられ、更に上方に折り曲げられてなるそれぞれの補強縁部13dを有している。 6 (a) and 6 (b) are a perspective view and a cross-sectional view showing the cross rail 13, respectively. As shown in FIGS. 6A and 6B, the horizontal rail 13 includes a guide rail 13a projecting in a convex shape, each mounting plate 13b provided on the same plane on both sides of the guide rail 13a, and each mounting plate. Each side plate 13c is bent downward on both sides of 13b, and each reinforcing edge 13d is bent inward at one side of each side plate 13c and further bent upward.
 案内レール13aは、横桟13の長手方向に形成され、横桟13と同一の長さを有する。また、案内レール13aの複数箇所には、押え金具14を取付けるための1つの穿孔13eと一対のスリット13fが形成されている。 The guide rail 13 a is formed in the longitudinal direction of the horizontal rail 13 and has the same length as the horizontal rail 13. Further, a plurality of holes 13e and a pair of slits 13f for attaching the presser fitting 14 are formed at a plurality of locations on the guide rail 13a.
 各載置板13bも、横桟13の長手方向に形成され、横桟13と同一の長さを有する。また、各載置板13bには、案内レール13aに形成された穿孔13eを挟むようにして各開口部13iが形成されている。 Each mounting plate 13 b is also formed in the longitudinal direction of the horizontal beam 13 and has the same length as the horizontal beam 13. Each mounting plate 13b has an opening 13i so as to sandwich a perforation 13e formed in the guide rail 13a.
 また、横桟13の案内レール13aの両端部には、3個の穿孔13gがそれぞれ形成され、同様に横桟13の各側板13cの両端部にも、3個の穿孔13hがそれぞれ形成されている。 Further, three perforations 13g are formed at both ends of the guide rail 13a of the horizontal rail 13, and similarly, three perforations 13h are formed at both ends of each side plate 13c of the horizontal rail 13, respectively. Yes.
 ここで、横桟13をX方向に極めて長く設ける必要があるものの、そのような長さを単一の部材で実現するのは困難である。このため、複数の横桟13を連結することにより、長い横桟13を形成している。 Here, although it is necessary to provide the horizontal rail 13 extremely long in the X direction, it is difficult to realize such a length with a single member. For this reason, the long horizontal rail 13 is formed by connecting the several horizontal rail 13.
 図7(a)、(b)は、それぞれ複数の横桟13を連結するための内部連結部材23を示す斜視図及び平面図である。斜視図である。図7(a)、(b)に示すように内部連結部材23は、主板23b、及び主板23bの両側で折り曲げられた各側板23aを有しており、その断面形状が概ねC型となっている。主板23bには、6個のネジ孔23cが内部連結部材23の長手方向に並んで形成され、また各側板23aにも、6個のネジ孔23dが内部連結部材23の長手方向に並んで形成されている。 7 (a) and 7 (b) are a perspective view and a plan view showing an internal connection member 23 for connecting a plurality of horizontal rails 13, respectively. It is a perspective view. As shown in FIGS. 7A and 7B, the internal connecting member 23 has a main plate 23b and side plates 23a bent on both sides of the main plate 23b, and the cross-sectional shape thereof is substantially C-shaped. Yes. Six screw holes 23 c are formed in the main plate 23 b along the longitudinal direction of the internal connection member 23, and six screw holes 23 d are formed in each side plate 23 a along the longitudinal direction of the internal connection member 23. Has been.
 内部連結部材23の各側板23aの外側幅は、横桟13の各側板13cの内側の間隔よりも僅かに短くされ、横桟13の各側板13cの内側に外部連結部材23の各側板23aを挿入して抱え込むことができるようにされている。 The outer width of each side plate 23 a of the internal connection member 23 is slightly shorter than the inner space of each side plate 13 c of the horizontal beam 13, and each side plate 23 a of the external connection member 23 is placed inside each side plate 13 c of the horizontal beam 13. It can be inserted and carried.
 図8は、2本の横桟13の連結構造を示す分解斜視図である。図8に示すように2本の横桟13の端部同士を突合せ、各横桟13の端部から該各横桟13の内側へと内部連結部材23を挿入して配置する。このとき、内部連結部材23の中心が各横桟13の継ぎ目に略重なるように内部連結部材23の位置を調節して、内部連結部材23の片側半分が一方の横桟13内側に配置され、かつ内部連結部材23の他の片側半分が他方の横桟13内側に配置されるようにする。この状態では、内部連結部材23の片側半分の主板23bの各ネジ孔23c及び各側板23aの各ネジ孔23dが一方の横桟13の案内レール13aの各穿孔13g及び各側板13cの各穿孔13hに重なり、各ボルト26を一方の横桟13の各穿孔13g、13hを通じて内部連結部材23の片側半分の各ネジ孔23c、23dにねじ込むことができ、同様に内部連結部材23の他の片側半分の主板23bの各ネジ孔23c及び各側板23aの各ネジ孔23dが他方の横桟13の案内レール13aの各穿孔13g及び各側板13cの各穿孔13hに重なり、各ボルト26を他方の横桟13の各穿孔13g、13hを通じて内部連結部材23の他の片側半分の各ネジ孔23c、23dにねじ込むことができ、これにより内部連結部材23を介して、2本の横桟13を連結することができる。 FIG. 8 is an exploded perspective view showing the connecting structure of the two horizontal rails 13. As shown in FIG. 8, the end portions of the two horizontal rails 13 are abutted with each other, and the internal connection members 23 are inserted and arranged from the end portions of the horizontal rails 13 to the inside of the horizontal rails 13. At this time, the position of the internal connection member 23 is adjusted so that the center of the internal connection member 23 substantially overlaps the seam of each horizontal beam 13, and one half of the internal connection member 23 is arranged inside one horizontal beam 13, In addition, the other half of the inner connecting member 23 is arranged inside the other horizontal rail 13. In this state, each screw hole 23c of the main plate 23b on one side half of the internal connecting member 23 and each screw hole 23d of each side plate 23a are each perforation 13g of the guide rail 13a of each side rail 13 and each perforation 13h of each side plate 13c. The bolts 26 can be screwed into the screw holes 23c and 23d on one half of the internal connection member 23 through the perforations 13g and 13h of the one side rail 13, and the other half on the other side of the internal connection member 23. The screw holes 23c of the main plate 23b and the screw holes 23d of the side plates 23a overlap with the perforations 13g of the guide rail 13a of the other side rail 13 and the perforations 13h of the side plates 13c. 13 can be screwed into the screw holes 23c, 23d on the other half of the inner connecting member 23 through the perforations 13g, 13h. Te can couple the two horizontal crosspieces 13.
 次に、横桟13を縦桟12に接続固定するための構造について説明する。 Next, a structure for connecting and fixing the horizontal beam 13 to the vertical beam 12 will be described.
 図9(a)、(b)は、それぞれ横桟13を縦桟12に接続固定するための取付け金具24を示す斜視図及び側面図である。図9(a)、(b)に示すように取付け金具24は、主板24b、主板24bの対向2辺で上方に折り曲げられた各側板24a、各側板24aとは鋭角をなすように該各側板24aの一辺で外側に折り曲げられたそれぞれの嵌合板24c、及び主板24bの他の対向2辺で上方に折り曲げられて折り返され、主板24bの下方に突出した各補強板24dを有している。主板24bの中央には、ネジ孔24eが形成されている。 9 (a) and 9 (b) are a perspective view and a side view showing a mounting bracket 24 for connecting and fixing the horizontal beam 13 to the vertical beam 12, respectively. As shown in FIGS. 9 (a) and 9 (b), the mounting bracket 24 includes a main plate 24b, side plates 24a bent upward at two opposite sides of the main plate 24b, and each side plate so as to form an acute angle with each side plate 24a. Each of the fitting plates 24c is bent outward at one side of 24a, and each reinforcing plate 24d is bent back and bent upward at the other two opposite sides of the main plate 24b and protrudes below the main plate 24b. A screw hole 24e is formed in the center of the main plate 24b.
 取付け金具24の各補強板24dの内側の間隔は、縦桟12の天板12bの幅よりも長くされており、縦桟12の天板12bを取付け金具24の各補強板24dの内側に配置して、取付け金具24の主板24bを天板12bに重ねることができるようにされている。 The inner space of each reinforcing plate 24 d of the mounting bracket 24 is longer than the width of the top plate 12 b of the vertical beam 12, and the top plate 12 b of the vertical beam 12 is arranged inside each reinforcing plate 24 d of the mounting bracket 24. Thus, the main plate 24b of the mounting bracket 24 can be overlaid on the top plate 12b.
 図10は、縦桟12に対する横桟13の接続構造を示す斜視図である。図10に示すように横桟13を縦桟12上に載せて、横桟13の各補強縁部13dの内側に縦桟12の天板12bの長形孔12eが来るように横桟13の位置を調節する。そして、横桟13の内側に取付け金具24を配置し、取付け金具24の各補強板24dの内側に縦桟12の天板12bを嵌め入れて、取付け金具24の主板24bを縦桟12の天板12bに重ね、取付け金具24の各嵌合板24cを横桟13の各補強縁部13dの内側に差込み、取付け金具24の主板24bのネジ孔24eを縦桟12の天板12bの長形孔12eに重ね合わせる。この後、ボルト25をワッシャ及び天板12bの長形孔12eに通して主板24bのネジ孔24eにねじ込んで締め付ける。これにより、縦桟12の天板12bと取付け金具24の主板24bとが相互に密接して固定され、縦桟12の天板12bと取付け金具24の各嵌合板24cとの間に各横桟13の各補強縁部13dが挟み込まれて固定され、横桟13が縦桟12に接続固定される。 FIG. 10 is a perspective view showing a connection structure of the horizontal beam 13 to the vertical beam 12. As shown in FIG. 10, the horizontal beam 13 is placed on the vertical beam 12, and the elongated beam 12 e of the top plate 12 b of the vertical beam 12 is placed inside each reinforcing edge 13 d of the horizontal beam 13. Adjust the position. Then, the mounting bracket 24 is disposed inside the horizontal rail 13, the top plate 12 b of the vertical rail 12 is fitted inside each reinforcing plate 24 d of the mounting bracket 24, and the main plate 24 b of the mounting bracket 24 is attached to the top of the vertical rail 12. Overlaid on the plate 12b, each fitting plate 24c of the mounting bracket 24 is inserted inside each reinforcing edge 13d of the horizontal rail 13, and the screw hole 24e of the main plate 24b of the mounting bracket 24 is a long hole of the top plate 12b of the vertical rail 12. 12e. Thereafter, the bolt 25 is passed through the washer and the elongated hole 12e of the top plate 12b and screwed into the screw hole 24e of the main plate 24b to be tightened. Thereby, the top plate 12b of the vertical beam 12 and the main plate 24b of the mounting bracket 24 are fixed in close contact with each other, and each horizontal beam is interposed between the top plate 12b of the vertical beam 12 and each fitting plate 24c of the mounting bracket 24. Each reinforcing edge 13 d of 13 is sandwiched and fixed, and the horizontal beam 13 is connected and fixed to the vertical beam 12.
 尚、ボルト25を緩めた状態では、横桟13を図1のX方向に移動させて、横桟13のX方向の位置を調節することができる。 In the state where the bolts 25 are loosened, the horizontal beam 13 can be moved in the X direction in FIG. 1 to adjust the position of the horizontal beam 13 in the X direction.
 このような取付け金具24を用いることにより接続構造の部品点数を節減することができる。また、取付け金具24の各補強板24dの内側に縦桟12の天板12bが嵌め入れられることにより取付け金具24に対する縦桟12の向きが決まり、かつ取付け金具24の各嵌合板24cが横桟13の各補強縁部13dの内側に差込まれることにより取付け金具24に対する横桟13の向きが決まり、また取付け金具24の各補強板24dと各嵌合板24cが相互に直交していることから、縦桟12と横桟13間の角度が自動的に直角に設定される。 By using such a mounting bracket 24, the number of parts of the connection structure can be reduced. Further, the top plate 12b of the vertical beam 12 is fitted inside each reinforcing plate 24d of the mounting bracket 24, whereby the orientation of the vertical beam 12 with respect to the mounting bracket 24 is determined, and each fitting plate 24c of the mounting bracket 24 is fixed to the horizontal beam. 13 is inserted into the inside of each reinforcing edge 13d, and the orientation of the cross rail 13 with respect to the mounting bracket 24 is determined, and each reinforcing plate 24d and each fitting plate 24c of the mounting bracket 24 are orthogonal to each other. The angle between the vertical beam 12 and the horizontal beam 13 is automatically set to a right angle.
 また、縦桟12の天板12bの各長形孔12eの間隔に応じて各横桟13の間隔が決まり、各横桟13の案内レール13a間のスペースの幅Sw(図1に示す)が決まる。縦桟12の天板12bの各長形孔12eの間隔は、各横桟13の案内レール13a間のスペースの幅Swが太陽電池モジュール16の幅Tw(図2に示す)よりも僅かに長くなるように予め設定されている。また、縦桟12の天板12bの各長形孔12eが縦桟12の長手方向(Y方向)に長く、ボルト25を緩めた状態では、横桟13をY方向に移動させて、各横桟13の案内レール13a間の間隔を調節することができる。このため、図1に示すように太陽電池モジュール16の短い方の対向2辺の方向で、太陽電池モジュール16を各横桟13間に架け渡して、太陽電池モジュール16の長い方の対向2辺端部16aを各横桟13の載置板13b上に載せることができる。 Further, the interval between the horizontal beams 13 is determined according to the interval between the elongated holes 12e of the top plate 12b of the vertical beam 12, and the width Sw (shown in FIG. 1) between the guide rails 13a of each horizontal beam 13 is determined. Determined. The interval between the elongated holes 12e of the top plate 12b of the vertical beam 12 is such that the width Sw of the space between the guide rails 13a of each horizontal beam 13 is slightly longer than the width Tw (shown in FIG. 2) of the solar cell module 16. It is preset so that Further, in a state where the long holes 12e of the top plate 12b of the vertical beam 12 are long in the longitudinal direction (Y direction) of the vertical beam 12 and the bolt 25 is loosened, the horizontal beam 13 is moved in the Y direction to The interval between the guide rails 13a of the crosspiece 13 can be adjusted. For this reason, as shown in FIG. 1, the solar cell module 16 is bridged between the horizontal rails 13 in the direction of the shorter two opposite sides of the solar cell module 16, and the longer opposite two sides of the solar cell module 16 are The end portion 16a can be placed on the mounting plate 13b of each horizontal rail 13.
 次に、太陽電池モジュール16の端部16aの固定構造について説明する。太陽電池モジュール16の端部16aは、横桟13上の押え金具14と受け金具(図1に示さず)とを組み合わせて固定される。 Next, the fixing structure of the end 16a of the solar cell module 16 will be described. The end 16a of the solar cell module 16 is fixed by combining the presser fitting 14 on the cross rail 13 and a receiving metal fitting (not shown in FIG. 1).
 図11(a)、(b)は、それぞれ押え金具14を示す斜視図及び側面図である。図11(a)、(b)に示すように押え金具14は、主板14a、及び主板14aの両側で下方に折り曲げられたそれぞれの差込み片14bを有している。主板14aの中央には、ネジ孔14cが形成されている。 11 (a) and 11 (b) are a perspective view and a side view showing the presser fitting 14, respectively. As shown in FIGS. 11A and 11B, the presser fitting 14 has a main plate 14a and respective insertion pieces 14b bent downward on both sides of the main plate 14a. A screw hole 14c is formed in the center of the main plate 14a.
 また、主板14aの下面には、各差込み片14bの中心を通る仮想中心線の両側に配されたそれぞれの弾性部材(例えばゴム材)27が貼り付けられている。各弾性部材27の間隔は、横桟13の案内レール13aの幅よりも広くされており、各弾性部材27の間に案内レール13aを入れることができる。 Further, on the lower surface of the main plate 14a, respective elastic members (for example, rubber materials) 27 disposed on both sides of a virtual center line passing through the center of each insertion piece 14b are attached. The interval between the elastic members 27 is wider than the width of the guide rails 13 a of the horizontal rail 13, and the guide rails 13 a can be inserted between the elastic members 27.
 図12は、押え金具14と組み合わせて用いられる受け金具を示す斜視図である。図12に示すように受け金具31は、主板31a、主板31aの両側で折り曲げられた各側板31b、及び主板31aの前後で折り曲げられた各補強部31cを有している。主板31aには、ネジ孔31dが形成されている。また、各側板31bには、外側に突出するストッパー部31eが2つずつ形成されている。これらのストッパー部31eは、三角錐状のものであり、それらの先端が主板31a側に向く。 FIG. 12 is a perspective view showing a receiving metal fitting used in combination with the holding metal fitting 14. As shown in FIG. 12, the metal fitting 31 includes a main plate 31a, side plates 31b bent on both sides of the main plate 31a, and reinforcing portions 31c bent on the front and rear sides of the main plate 31a. A screw hole 31d is formed in the main plate 31a. Each side plate 31b has two stopper portions 31e protruding outward. These stopper portions 31e have a triangular pyramid shape, and their tips are directed to the main plate 31a side.
 また、主板31aの上面には、各補強部31cの中心を通る仮想中心線の両側に配されたそれぞれの弾性部材(例えばゴム材)32が貼り付けられている。各弾性部材27の間隔は、横桟13の案内レール13a両側の各開口部13iの間隔に応じて設定されており、受け金具31を横桟13の内側に配した状態で、受け金具31の各弾性部材27を横桟13の各開口部13iにそれぞれ重ね合わせることができる。 Further, elastic members (for example, rubber materials) 32 disposed on both sides of a virtual center line passing through the center of each reinforcing portion 31c are attached to the upper surface of the main plate 31a. The interval between the elastic members 27 is set in accordance with the interval between the openings 13 i on both sides of the guide rail 13 a of the horizontal rail 13. Each elastic member 27 can be overlaid on each opening 13 i of the cross rail 13.
 ここで、受け金具31の各側板31bの外側幅は、横桟13の各補強縁部13dの内側の間隔よりも僅かに短くされており、受け金具31の各側板31bを横桟13の各補強縁部13dの間に挿入することができる。 Here, the outer width of each side plate 31b of the metal fitting 31 is slightly shorter than the inner space of each reinforcing edge portion 13d of the horizontal beam 13, and each side plate 31b of the metal fitting 31 is connected to each side beam 13 of each horizontal beam 13. It can be inserted between the reinforcing edges 13d.
 また、各側板31bの各ストッパー部31e間の外側距離、つまり一方の側板31bのストッパー部31eの外側頂点から他方の側板31bのストッパー部31eの外側頂点までの距離は、横桟13の各補強縁部13dの内側の間隔よりも僅かに長くされている。従って、受け金具31の各側板31bを横桟13の各補強縁部13dの間に挿入すると、各側板31bの各ストッパー部31eが横桟13の各補強縁部13dの内側に引っ掛かることになる。ところが、各ストッパー部31eが三角錐状のものであるから、受け金具31の各側板31bを強く押し込むと、各ストッパー部31eが横桟13の各補強縁部13dを押し広げながら該各補強縁部13dの上方に侵入して行く。そして、各ストッパー部31eが各補強縁部13dの上方に一旦侵入すると、三角錐状の各ストッパー部31eの下端が各補強縁部13dに引っ掛かって、受け金具31が横桟13の内側から抜けなくなり、受け金具31が横桟13の内側で昇降移動出来るように支持され、受け金具31の下降が制限される。 Further, the outer distance between the stopper portions 31e of each side plate 31b, that is, the distance from the outer vertex of the stopper portion 31e of one side plate 31b to the outer vertex of the stopper portion 31e of the other side plate 31b, It is slightly longer than the interval inside the edge portion 13d. Accordingly, when the side plates 31b of the metal fitting 31 are inserted between the reinforcing edge portions 13d of the horizontal rail 13, the stopper portions 31e of the side plates 31b are caught inside the reinforcing edge portions 13d of the horizontal rail 13. . However, since each stopper portion 31e has a triangular pyramid shape, when each side plate 31b of the receiving bracket 31 is pushed in strongly, each stopper portion 31e pushes and spreads each reinforcing edge portion 13d of the horizontal rail 13 while expanding each reinforcing edge. It enters above the portion 13d. Then, once each stopper portion 31e enters above each reinforcing edge portion 13d, the lower end of each triangular pyramid-shaped stopper portion 31e is hooked on each reinforcing edge portion 13d, and the catch 31 is pulled out from the inside of the horizontal rail 13. The receiving bracket 31 is supported so that it can be moved up and down inside the horizontal rail 13, and the lowering of the receiving bracket 31 is restricted.
 図13及び図14は、横桟13に対する押え金具14及び受け金具31の取付け構造を示す斜視図及び側面図である。図13及び図14に示すように横桟13の各開口部13iの箇所で、横桟13の各補強縁部13dの間に受け金具31の各側板31bを挿入して、受け金具31の各ストッパー部31eを横桟13の各補強縁部13dの上方まで押し込んで、受け金具31の各ストッパー部31eを横桟13の各補強縁部13dに引っ掛け、受け金具31を横桟13の内側に昇降移動出来るように支持し、受け金具31の下降を制限する。このとき、受け金具31のネジ孔31dが横桟13の案内レール13の穿孔13eの下方に位置し、かつ受け金具31の各弾性部材32が横桟13の各載置板13bの開口部13iの下方に位置するように、受け金具31を位置決めする。 FIGS. 13 and 14 are a perspective view and a side view showing a mounting structure of the holding metal fitting 14 and the receiving metal fitting 31 with respect to the horizontal rail 13. As shown in FIGS. 13 and 14, the side plates 31 b of the metal fittings 31 are inserted between the reinforcing edge portions 13 d of the horizontal rails 13 at the positions of the openings 13 i of the horizontal rails 13. The stopper portion 31e is pushed up to above the reinforcing edge portions 13d of the horizontal beam 13, and the stopper portions 31e of the receiving bracket 31 are hooked on the reinforcing edge portions 13d of the horizontal beam 13, so that the receiving metal plate 31 is placed inside the horizontal beam 13. It supports so that it can move up and down, and restricts the descent of the receiving metal 31. At this time, the screw hole 31d of the receiving metal 31 is located below the perforation 13e of the guide rail 13 of the horizontal rail 13, and each elastic member 32 of the receiving metal 31 is the opening 13i of each mounting plate 13b of the horizontal rail 13. The receiving metal fitting 31 is positioned so as to be positioned below.
 また、ボルト33をワッシャに通して押え金具14の主板14aのネジ孔14cにネジ込んでおく。図15に拡大して示すようにボルト33の頭部33a直下には雄ネジ33bを部分的に削除してなる括れ部33cが形成されており、この括れ部33cの外径が雄ネジ33bの外径よりも小さくなっている。このため、ボルト33の括れ部33cが押え金具14のネジ孔14cに達するまで、ボルト33をネジ込んで行くと、押え金具14のネジ孔14cがボルト33の括れ部33cに引っ掛かって、押え金具14がボルト33の括れ部33cに回転可能に係合しかつ落下しなくなる。 Further, the bolt 33 is passed through a washer and screwed into the screw hole 14c of the main plate 14a of the presser fitting 14. As shown in an enlarged view in FIG. 15, a constricted portion 33c formed by partially removing the male screw 33b is formed immediately below the head 33a of the bolt 33, and the constricted portion 33c has an outer diameter of the male screw 33b. It is smaller than the outer diameter. For this reason, when the bolt 33 is screwed in until the constricted portion 33c of the bolt 33 reaches the screw hole 14c of the retainer 14, the screw hole 14c of the retainer 14 is caught by the constricted portion 33c of the bolt 33, and the retainer 14 is rotatably engaged with the constricted portion 33c of the bolt 33 and does not fall.
 この押え金具14の各差込み片14bを横桟13の案内レール13aの各スリット13fに差込み、押え金具14が係合したボルト33を横桟13の案内レール13aの穿孔13eに通して受け金具31の主板31aのネジ孔31dにねじ込むと、受け金具31の各ストッパー部31eが横桟13の各補強縁部13dに引っ掛って、受け金具31の下降が制限されていることから、ボルト33が横桟13の案内レール13a上に突出した状態で支持され、押え金具14が横桟13の案内レール13aから上方に離間して配置される。このとき、押え金具14の主板14a下面の各弾性部材27と横桟13の各載置板13bとの間隔が太陽電池モジュール16の端部16aの厚みよりも広くなるように、受け金具31のネジ孔31dに対するボルト33のねじ込み量を調節しておく。 Each insertion piece 14b of the presser fitting 14 is inserted into each slit 13f of the guide rail 13a of the horizontal rail 13, and the bolt 33 engaged with the presser fitting 14 is passed through the perforation 13e of the guide rail 13a of the horizontal rail 13 to receive the metal fitting 31. When the main plate 31a is screwed into the screw hole 31d, each stopper portion 31e of the receiving bracket 31 is hooked on each reinforcing edge portion 13d of the horizontal rail 13, and the lowering of the receiving bracket 31 is restricted. The support bar 14 is supported in a state of protruding on the guide rail 13 a of the horizontal rail 13, and the presser fitting 14 is arranged to be spaced upward from the guide rail 13 a of the horizontal rail 13. At this time, the metal fittings 31 are arranged so that the distance between each elastic member 27 on the lower surface of the main plate 14 a of the presser fitting 14 and each mounting plate 13 b of the horizontal rail 13 is wider than the thickness of the end portion 16 a of the solar cell module 16. The screwing amount of the bolt 33 into the screw hole 31d is adjusted.
 この状態では、押え金具14の主板14a下面の各弾性部材27と受け金具31の主板31a上面の各弾性部材32が、横桟13の各載置板13bの上方及び下方に在り、各載置板13bの開口部13iを通じて対向する。 In this state, the elastic members 27 on the lower surface of the main plate 14 a of the presser fitting 14 and the elastic members 32 on the upper surface of the main plate 31 a of the receiving metal fitting 31 are located above and below the respective mounting plates 13 b of the horizontal rail 13. It opposes through the opening part 13i of the board 13b.
 こうして押え金具14及び受け金具31を横桟13に取付けた状態で、太陽電池モジュール16の端部16aを押え金具14の主板14a下面の各弾性部材27と横桟13の各載置板13bとの間に挿入する。この後、ボルト33をねじ込んで行くと、ボルト33の括れ部33cに係合した押え金具14が下降して行き、押え金具14の主板14aが横桟13の案内レール13aに当接して、押え金具14が横桟13の各載置板13上側に位置決めされ、押え金具14の主板14a下面の各弾性部材27が案内レール13a上面よりも下方に突出する。更に、ボルト33をねじ込んで行くと、押え金具14が案内レール13aに当接して下降しないことから、ボルト33により受け金具31が持ち上げられ、受け金具31の主板31aが横桟13の各載置板13b下面に当接するまで、受け金具31が上昇し、受け金具31の主板31a上面の各弾性部材32が横桟13の各載置板13bの開口部13iを通じて該各載置板13bの上方に突出する。 With the presser fitting 14 and the receiving metal fitting 31 attached to the horizontal rail 13 in this way, the end 16a of the solar cell module 16 is connected to the elastic members 27 on the lower surface of the main plate 14a of the presser fixture 14 and the mounting plates 13b of the horizontal rail 13. Insert between. Thereafter, when the bolt 33 is screwed in, the presser fitting 14 engaged with the constricted portion 33c of the bolt 33 descends, and the main plate 14a of the presser fitting 14 comes into contact with the guide rail 13a of the cross rail 13 to hold the presser. The metal fitting 14 is positioned above each mounting plate 13 of the horizontal rail 13, and each elastic member 27 on the lower surface of the main plate 14a of the presser fitting 14 protrudes downward from the upper surface of the guide rail 13a. Further, when the bolts 33 are screwed in, the presser fittings 14 come into contact with the guide rails 13a and do not move down, so that the receiving fittings 31 are lifted by the bolts 33, and the main plate 31a of the receiving fittings 31 is placed on the respective horizontal rails 13. Until the abutting against the lower surface of the plate 13b, the receiving metal 31 is raised, and the elastic members 32 on the upper surface of the main plate 31a of the receiving metal 31 are located above the respective mounting plates 13b through the openings 13i of the respective mounting plates 13b. Protrusively.
 このとき、図16に示すように受け金具31の主板31a上面の各弾性部材32により太陽電池モジュール16の端部16aが押し上げられて横桟13の各載置板13bから離間した状態となり、太陽電池モジュール16の端部が押え金具14の主板14a下面の各弾性部材27と受け金具31の主板31a上面の各弾性部材32との間に挟み込まれて支持される。 At this time, as shown in FIG. 16, the end portions 16 a of the solar cell module 16 are pushed up by the elastic members 32 on the upper surface of the main plate 31 a of the metal fitting 31 to be separated from the mounting plates 13 b of the horizontal rails 13. The ends of the battery module 16 are sandwiched and supported between the elastic members 27 on the lower surface of the main plate 14 a of the presser fitting 14 and the elastic members 32 on the upper surface of the main plate 31 a of the receiving metal fitting 31.
 そして、ボルト33を締め付けると、押え金具14の主板14aが横桟13の案内レール13aに当接し、かつ受け金具31の主板31aが横桟13の各載置板13bに当接して、太陽電池モジュール16の端部が押え金具14の各弾性部材27と受け金具31の各弾性部材32との間に挟み込まれて支持された状態が維持される。 When the bolts 33 are tightened, the main plate 14a of the presser fitting 14 comes into contact with the guide rail 13a of the horizontal rail 13, and the main plate 31a of the receiving fixture 31 comes into contact with each mounting plate 13b of the horizontal rail 13, so that the solar cell The state where the end portion of the module 16 is sandwiched and supported between the elastic members 27 of the presser fitting 14 and the elastic members 32 of the support fitting 31 is maintained.
 ここで、図17に示すように横桟13の載置板13bからの案内レール13aの高さh1は、太陽電池モジュール16の端部16aの厚みh2と、非圧縮時の弾性部材27の厚みh3と、載置板13bからの非圧縮時の弾性部材32の突出高さh4との和よりも低くされている(h1<h2+h3+h4)。このため、図16に示すようにボルト33が締め付けられ、押え金具14の主板14aが横桟13の案内レール13aに当接して、押え金具14の主板14aと横桟13の載置板13bとの間隔が高さh1となり、また高さh1の間隔に太陽電池モジュール16の端部16aと、弾性部材27と、載置板13bから突出した弾性部材32が挟み込まれると、各弾性部材27、32が圧縮されて、太陽電池モジュール16の端部が押え金具14の弾性部材27と受け金具31の弾性部材32との間に挟み込まれて支持される。 Here, as shown in FIG. 17, the height h1 of the guide rail 13a from the mounting plate 13b of the horizontal rail 13 is the thickness h2 of the end portion 16a of the solar cell module 16 and the thickness of the elastic member 27 when not compressed. It is lower than the sum of h3 and the protruding height h4 of the elastic member 32 when not compressed from the mounting plate 13b (h1 <h2 + h3 + h4). For this reason, as shown in FIG. 16, the bolt 33 is tightened, the main plate 14a of the presser fitting 14 comes into contact with the guide rail 13a of the horizontal rail 13, and the main plate 14a of the presser fixture 14 and the mounting plate 13b of the horizontal rail 13 When the end portion 16a of the solar cell module 16, the elastic member 27, and the elastic member 32 protruding from the mounting plate 13b are sandwiched between the height h1 and the interval h1, the elastic members 27, 32 is compressed, and the end of the solar cell module 16 is sandwiched and supported between the elastic member 27 of the presser fitting 14 and the elastic member 32 of the receiving fitting 31.
 また、横桟13の各載置板13bからの非圧縮時の弾性部材32の突出高さh4を充分な高さに設定している。これにより、図16に示すように太陽電池モジュール16の端部16aが受け金具31の弾性部材32に載って、ボルト33が締め付けられ、受け金具31の弾性部材32が圧縮されたときでも、太陽電池モジュール16の端部が載置板13bから離間して支持される。 Further, the protruding height h4 of the elastic member 32 when not compressed from each mounting plate 13b of the horizontal rail 13 is set to a sufficient height. As a result, as shown in FIG. 16, even when the end 16 a of the solar cell module 16 is placed on the elastic member 32 of the metal fitting 31, the bolt 33 is tightened, and the elastic member 32 of the metal fitting 31 is compressed, The end of the battery module 16 is supported while being separated from the placement plate 13b.
 すなわち、押え金具14と受け金具31に挟まれる横桟13の載置板13bの領域を太陽電池モジュール16の端部16aを固定する固定部位とすると、押え金具(押え部材)14を固定部位の上側(横桟13の案内レール13a)に配置し、受け金具(受け部材)31を固定部位の下側(横桟13の内側)で昇降移動出来るように設け、押え金具14と受け金具31をボルト33により連結して締め付けることにより、受け金具31の各弾性部材32を載置板13bの開口部13iを通じて該載置板13bの上方に突出させ、太陽電池モジュール16の端部を押え金具14の各弾性部材27と受け金具31の各弾性部材32との間に挟み込んで支持しているといえる。 That is, when the region of the mounting plate 13b of the horizontal rail 13 sandwiched between the presser fitting 14 and the receiving metal fixture 31 is a fixing portion for fixing the end portion 16a of the solar cell module 16, the presser fitting (pressing member) 14 is the fixing portion. It is arranged on the upper side (guide rail 13a of the horizontal rail 13), and a receiving bracket (receiving member) 31 is provided so that it can be moved up and down below the fixed part (inside the horizontal rail 13). By connecting and tightening with bolts 33, each elastic member 32 of the receiving metal fitting 31 protrudes above the mounting plate 13 b through the opening portion 13 i of the mounting plate 13 b, and the end of the solar cell module 16 is pressed against the holding metal fitting 14. It can be said that each of the elastic members 27 and each elastic member 32 of the metal fitting 31 are sandwiched and supported.
 次に、本実施形態の太陽電池モジュールの架台の施工方法を説明する。 Next, a method for constructing the solar cell module mount of the present embodiment will be described.
 まず、図1に示すように各支柱11を等間隔に配して突設し、各支柱11の上端部にそれぞれの縦桟12の中央部を接続して、各縦桟12を傾斜させて固定しておく。 First, as shown in FIG. 1, the columns 11 are projected at equal intervals, and the central portion of each vertical beam 12 is connected to the upper end of each column 11, and each vertical beam 12 is inclined. Keep it fixed.
 また、横桟13における穿孔13e、各スリット13f、及び各開口部13iの形成箇所に、ボルト33が係合した押え金具14及び受け金具31を取付ける。このとき、押え金具14の各弾性部材27の下面と横桟13の各載置板13bの上面との間の間隔が太陽電池モジュール16の端部16aの厚み以上となるように、ボルト33を受け金具31の主板31aのネジ孔31dにねじ込んで、押え金具14を保持する。また、押え金具14の各弾性部材27と受け金具31の各弾性部材32を、横桟13の各載置板13bの上方及び下方に配し、各載置板13bの開口部13iを通じて対向させる。 Also, the holding metal fitting 14 and the receiving metal fitting 31 engaged with the bolts 33 are attached to the positions where the perforations 13e, the slits 13f, and the opening portions 13i are formed in the horizontal rail 13. At this time, the bolts 33 are attached so that the distance between the lower surface of each elastic member 27 of the presser fitting 14 and the upper surface of each mounting plate 13b of the horizontal rail 13 is equal to or greater than the thickness of the end portion 16a of the solar cell module 16. The presser fitting 14 is held by being screwed into the screw holes 31d of the main plate 31a of the support fitting 31. Further, the elastic members 27 of the holding metal fitting 14 and the elastic members 32 of the metal fitting 31 are arranged above and below the respective mounting plates 13b of the horizontal rail 13, and are opposed to each other through the openings 13i of the respective mounting plates 13b. .
 ただし、各横桟13の一端側に最も近い4組の押え金具14と受け金具31の取付けを行わない。 However, the four sets of presser fittings 14 and the receiving metal fittings 31 that are closest to one end of each crosspiece 13 are not attached.
 次に、図8に示すような連結構造により複数の横桟13を連結して、4本の長い横桟13を形成し、各横桟13を平行に並べる。そして、図18に示すように各横桟13と直交する複数の補助桟15を配して、各補助桟15を各横桟13の底面に固定し、各横桟13と各補助桟15を井桁状に組み合わせる。更に、複数の作業員もしくはクレーンにより、井桁状に組み合わせられた各横桟13と各補助桟15を持ち上げて、各横桟13を各縦桟12と直交するように配して、各横桟13を各縦桟12上に載せ、各横桟13を平行に並べかつ相互に異なる高さに配置する。この後、図10に示すような固定構造により各横桟13を各縦桟12に接続固定する。 Next, a plurality of horizontal bars 13 are connected by a connecting structure as shown in FIG. 8 to form four long horizontal bars 13, and the horizontal bars 13 are arranged in parallel. Then, as shown in FIG. 18, a plurality of auxiliary rails 15 orthogonal to the respective horizontal rails 13 are arranged, each auxiliary rail 15 is fixed to the bottom surface of each horizontal rail 13, and each horizontal rail 13 and each auxiliary rail 15 are connected to each other. Combine like a cross. Further, each horizontal beam 13 and each auxiliary beam 15 combined in a cross beam shape are lifted by a plurality of workers or cranes, and each horizontal beam 13 is arranged so as to be orthogonal to each vertical beam 12. 13 are placed on each vertical rail 12, and the horizontal rails 13 are arranged in parallel and arranged at different heights. Thereafter, each horizontal beam 13 is connected and fixed to each vertical beam 12 by a fixing structure as shown in FIG.
 一方、各横桟13の一端側に、全ての太陽電池モジュール16を搬送して配置する。そして、隣り合う一対の横桟13の一端側近傍において、1枚目の太陽電池モジュール16を持ち上げて、太陽電池モジュール16の短い方の対向2辺の方向で、太陽電池モジュール16を各横桟13間に架け渡して、太陽電池モジュール16の長い方の対向2辺端部16aを各横桟13の載置板13b上に載せる。 On the other hand, all the solar cell modules 16 are transported and arranged on one end side of each horizontal rail 13. Then, in the vicinity of one end of a pair of adjacent horizontal rails 13, the first solar cell module 16 is lifted, and the solar cell modules 16 are moved to the respective horizontal rails in the direction of two opposite sides of the solar cell module 16. 13, the longer opposing two side end portions 16 a of the solar cell module 16 are placed on the mounting plate 13 b of each horizontal rail 13.
 そして、各横桟13の載置板13bで太陽電池モジュール16をスライドさせて、太陽電池モジュール16を各横桟13の一端側から他端側まで移動させる。このとき、各横桟13の案内レール13aが太陽電池モジュール16の両端部に摺接して、太陽電池モジュール16の落下が防止される。また、押え金具14の各弾性部材27の下面と横桟13の各載置板13bの上面との間の間隔が太陽電池モジュール16の端部16aの厚み以上に設定され、受け金具31の各弾性部材32が横桟13の各載置板13bの下方に配されているので、太陽電池モジュール16の端部が押え金具14の各弾性部材27や受け金具31の各弾性部材32に接触せず引っ掛かることもなく、太陽電池モジュール16の端部を各横桟13の載置板13b上で滑らかにスライドさせることができる。 Then, the solar cell module 16 is slid by the mounting plate 13b of each horizontal beam 13, and the solar cell module 16 is moved from one end side to the other end side of each horizontal beam 13. At this time, the guide rails 13a of the horizontal rails 13 are in sliding contact with both ends of the solar cell module 16, and the solar cell module 16 is prevented from falling. In addition, the distance between the lower surface of each elastic member 27 of the presser fitting 14 and the upper surface of each mounting plate 13b of the horizontal rail 13 is set to be equal to or greater than the thickness of the end portion 16a of the solar cell module 16, and Since the elastic member 32 is disposed below each mounting plate 13 b of the horizontal rail 13, the end of the solar cell module 16 is brought into contact with each elastic member 27 of the presser fitting 14 and each elastic member 32 of the receiving metal fitting 31. The end of the solar cell module 16 can be smoothly slid on the mounting plate 13b of each horizontal rail 13 without being caught.
 次に、2枚目の太陽電池モジュール16を持ち上げて各横桟13間に架け渡し、各横桟13上で太陽電池モジュール16を該各横桟13の一端側から既に搭載された1枚目の太陽電池モジュール16までスライドさせて移動させる。このとき、各太陽電池モジュール16の短い方の対向2辺端部16bにそれぞれの保護部材21を取付けていることから、各太陽電池モジュール16間に各保護部材21が挟み込まれ、各太陽電池モジュール16の短い方の対向2辺端部16bが直接接触することはない。 Next, the second solar cell module 16 is lifted and bridged between the horizontal rails 13, and the solar cell module 16 is mounted on each horizontal rail 13 from one end side of the horizontal rail 13. The solar cell module 16 is slid and moved. At this time, since the respective protective members 21 are attached to the shorter two opposite end portions 16b of the respective solar cell modules 16, the respective protective members 21 are sandwiched between the respective solar cell modules 16, and the respective solar cell modules. The shorter two opposite side edges 16b of 16 are not in direct contact with each other.
 3枚目以降の太陽電池モジュール16についても、同様の手順で各横桟13間に架け渡し、既に搭載された太陽電池モジュール16までスライドさせて移動させ、複数の太陽電池モジュール16を横一列に並べて搭載する。 The third and subsequent solar cell modules 16 are also spanned between the horizontal rails 13 in the same procedure, and are slid and moved to the already mounted solar cell modules 16 so that the plurality of solar cell modules 16 are arranged in a horizontal row. Install side by side.
 下側から1番目の横桟13と2番目の横桟13の間、2番目の横桟13と3番目の横桟13の間、及び3番目の横桟13と4番目の横桟13の間のいずれにも、複数の太陽電池モジュール16を横一列に並べて搭載する。 Between the first horizontal beam 13 and the second horizontal beam 13 from the lower side, between the second horizontal beam 13 and the third horizontal beam 13, and between the third horizontal beam 13 and the fourth horizontal beam 13. A plurality of solar cell modules 16 are mounted side by side in a row.
 この後、各横桟13において、各押え金具14のボルト33を締め付けて、押え金具14の各弾性部材27と受け金具31の各弾性部材32との間に各太陽電池モジュール16の端部を挟み込んで固定する。 Thereafter, the bolts 33 of the presser fittings 14 are tightened on the horizontal rails 13, and the end portions of the solar cell modules 16 are placed between the elastic members 27 of the presser fittings 14 and the elastic members 32 of the support fittings 31. Insert and fix.
 また、各横桟13の一端側に最も近い4組の押え金具14と受け金具31の取付けを行っていないので、この4組の押え金具14と受け金具31を取付けて、この4組の押え金具14と受け金具31によっても各太陽電池モジュール16の端部を固定する。 In addition, since the four sets of presser fittings 14 and the receiving brackets 31 that are closest to one end of each horizontal rail 13 are not attached, the four sets of presser fittings 14 and the receiving brackets 31 are attached, and the four sets of presser fittings are attached. The end of each solar cell module 16 is also fixed by the metal fitting 14 and the receiving metal 31.
 このように本実施形態の太陽電池モジュールの架台の施工方法では、各横桟13の一端側に全ての太陽電池モジュール16を搬送し、各太陽電池モジュール16を順次持ち上げて各横桟13の間に架け渡し、各太陽電池モジュール16を各横桟13上で順次スライドさせて並べているので、太陽電池モジュールの搭載作業が容易である。 As described above, in the method of installing the solar cell module mount of the present embodiment, all the solar cell modules 16 are transported to one end side of each horizontal beam 13, and each solar cell module 16 is sequentially lifted between the horizontal beams 13. Since the solar cell modules 16 are sequentially slid and arranged on the horizontal rails 13, the mounting operation of the solar cell modules is easy.
 また、押え金具14の各弾性部材27と横桟13の各載置板13bとの間隔が太陽電池モジュール16の端部の厚みよりも広く設定され、受け金具31の各弾性部材32が横桟13の各載置板13bの下方に配された状態で、太陽電池モジュール16の端部を横桟13の載置板13bに載せてスライドさせるので、太陽電池モジュール16を滑らかにスライドさせることができる。 In addition, the distance between each elastic member 27 of the presser fitting 14 and each mounting plate 13b of the horizontal rail 13 is set wider than the thickness of the end portion of the solar cell module 16, and each elastic member 32 of the receiving metal fitting 31 is set to the horizontal rail. Since the end of the solar cell module 16 is placed and slid on the mounting plate 13b of the horizontal rail 13 in a state of being arranged below the respective mounting plates 13b, the solar cell module 16 can be smoothly slid. it can.
 また、ボルト33を締め付けて、太陽電池モジュール16の端部16aを押え金具14の各弾性部材27と受け金具31の各弾性部材32との間に挟み込み、太陽電池モジュール16の端部を押え金具14の主板14a及び横桟13の載置板13bから離間させているので、ガラス板等からなる太陽電池モジュール16の端部16aが押え金具14の主板14aや横桟13の載置板13bに直接接触して欠けることはない。 Further, the bolt 33 is tightened so that the end 16a of the solar cell module 16 is sandwiched between the elastic members 27 of the presser fitting 14 and the elastic members 32 of the support fitting 31, and the end of the solar cell module 16 is held by the presser fitting. 14 is separated from the main plate 14a of the horizontal bar 13 and the mounting plate 13b of the horizontal beam 13, so that the end 16a of the solar cell module 16 made of a glass plate or the like is placed on the main plate 14a of the holding metal fitting 14 or the mounting plate 13b of the horizontal beam 13. There is no chipping due to direct contact.
 更に、太陽電池モジュール16の長い方の対向2辺端部16aを各横桟13上に載せて、太陽電池モジュール16の短い方の対向2辺の方向で、太陽電池モジュール16を各横桟13に架け渡している。これは、太陽電池モジュール16の長い方の対向2辺の方向での撓み量が短い方の対向2辺の方向での撓み量よりも大きいことから、長い方の対向2辺の方向よりも短い方の対向2辺の方向で、太陽電池モジュール16を各横桟13間に架け渡した方が、強度的に優れるためであり、また太陽電池モジュール16の補強部材を簡略化して、部品点数を削減し、コストを低減することができるためである。 Further, the long opposing two side end portions 16a of the solar cell module 16 are placed on the horizontal bars 13, and the solar cell module 16 is connected to the horizontal bars 13 in the direction of the two opposite short sides of the solar cell module 16. It is bridged over. This is because the amount of bending in the direction of the two opposite opposing sides of the solar cell module 16 is larger than the amount of bending in the direction of the two opposing opposing sides, so that it is shorter than the direction of the two opposing opposing sides. This is because it is superior in strength when the solar cell module 16 is bridged between the cross rails 13 in the direction of the two opposite sides, and the reinforcing member of the solar cell module 16 is simplified to reduce the number of parts. This is because the cost can be reduced.
 尚、上記実施形態の太陽電池モジュールの架台においては、全ての横桟13に案内レール13aを設けているが、横桟13上に太陽電池モジュール16を設置しないのであれば、横桟13の案内レール13aの全て又は一部を省略してもよい。例えば、図1の構成において、一番上(下側から4番目)の横桟13の案内レール13aを省略しても良い。 In the solar cell module mount of the above embodiment, the guide rails 13a are provided on all the horizontal rails 13, but if the solar cell module 16 is not installed on the horizontal rails 13, the guide of the horizontal rails 13 is provided. All or part of the rail 13a may be omitted. For example, in the configuration of FIG. 1, the guide rail 13a of the top (fourth from the bottom) horizontal rail 13 may be omitted.
