Description

本発明は、太陽電池モジュールを屋根などに取り付ける技術に関する。   The present invention relates to a technique for attaching a solar cell module to a roof or the like.
従来から、屋根などに太陽電池基板とフレームからなる太陽電池モジュールを取り付けるために様々な施工方法がある。
一例として、太陽電池パネルを支持金具で建物の屋根などの固定物に支持している太陽電池パネルの支持装置において、支持金具を、太陽電池パネル側の支持金具と、固定物側の支持金具とで構成し、一方の支持金具には縦長の長孔を、他方の支持金具には横長の長孔を形成し、両孔を通して止められるボルトで両支持金具を固定した構造がある(例えば、特許文献1)。
Conventionally, there are various construction methods for attaching a solar cell module including a solar cell substrate and a frame to a roof or the like.
As an example, in a solar cell panel support device in which a solar cell panel is supported by a support fixture on a fixed object such as a roof of a building, the support fixture includes a support fixture on the solar cell panel side, and a support fixture on a fixed object side. One support bracket has a vertically long hole, the other support bracket has a horizontally long hole, and both support brackets are fixed with bolts that can be stopped through both holes (for example, patents). Reference 1).
特開平2005−290755JP 2005-290755 A
しかし、上述の従来技術は、一方の金具に縦長の長孔を形成し、他方に横長の長孔を形成して、これら両孔を通してボルトで締める構成であったため、太陽電池モジュールの取付精度は、このボルトの締め具合により影響されてしまい、ボルトで締める際に両金具がずれてしまうことが多く、微妙な調整ができないという問題があった。特に、縦長の長孔は、垂直方向の加重がかかるため、わずかにボルトが緩んだり、金具を持っている手が緩んだ場合でも動いてしまい、微妙な調整が難しかった。   However, since the above-described conventional technology has a structure in which a vertically long slot is formed in one metal fitting and a horizontally long slot is formed in the other, and bolted through these holes, the mounting accuracy of the solar cell module is The bolts are affected by the degree of tightening, and both metal fittings are often displaced when tightened with bolts, and there is a problem that fine adjustment cannot be performed. In particular, since the vertically long slot is subjected to a vertical load, even if the bolt is slightly loosened or the hand holding the metal fitting is loosened, it has been difficult to make fine adjustments.
本発明は、上述の課題を解決するためになされたものであって、簡単で、かつ、太陽電池モジュールの取付位置の調整が容易な太陽電池モジュール取付構造を提供することを目的とする。   The present invention has been made to solve the above-described problems, and an object thereof is to provide a solar cell module mounting structure that is simple and that allows easy adjustment of the mounting position of the solar cell module.
上記目的を達成するため、本発明の一の観点にかかる太陽電池モジュール取付構造は、屋根などの取付面に太陽電池モジュールを取り付けるための取付構造であって、上記取付面の傾斜方向とほぼ直交する方向に横溝が形成された固定金具と、上記固定金具により取付面上に固定され、その中央部に上記屋根取付面の傾斜方向に形成された縦長の長穴が形成された縦材とを有し、上記横溝にボルトの頭部の大径部をスライドさせて嵌め込むと共に、ボルトのねじ部分を固定金具から上方に向かって突設させ、上記縦材の長穴に嵌めて固定する際に、上記ボルトを上記横溝に沿ってスライドさせると共に、上記縦材を上記長穴に沿って移動させることで上記縦材の取付位置を調整することを特徴とする。   In order to achieve the above object, a solar cell module mounting structure according to one aspect of the present invention is a mounting structure for mounting a solar cell module on a mounting surface such as a roof, and is substantially orthogonal to the inclination direction of the mounting surface. A fixing bracket having a transverse groove formed in the direction to be fixed, and a vertical member fixed on the mounting surface by the fixing bracket and having a vertically long slot formed in the inclined direction of the roof mounting surface at the center thereof. When the large diameter part of the bolt head is slid and fitted into the horizontal groove, the screw part of the bolt protrudes upward from the fixing bracket, and is fitted into the elongated hole of the vertical member for fixing. In addition, the bolt is slid along the transverse groove, and the vertical member is moved along the elongated hole to adjust the attachment position of the vertical member.
上記縦材には、係合部が形成されており、この係合部に太陽電池モジュールの上端部を引掛けると共に、上下に隣り合う太陽電池モジュール同士を互いに連結させてもよい。
また、上記取付面は、平型の屋根であってもよい。
An engaging portion is formed on the vertical member, and the upper end portion of the solar cell module may be hooked on the engaging portion, and the solar cell modules adjacent in the vertical direction may be connected to each other.
Further, the mounting surface may be a flat roof.
本発明によれば、部品点数も少なく、また太陽電池モジュールの取付が簡単で、その取付位置の調整が容易となる。   According to the present invention, the number of components is small, the solar cell module can be easily mounted, and the mounting position can be easily adjusted.
以下、本発明を適用した太陽電池モジュールの例を、図面を参照して説明する。
図1に本実施形態にかかる太陽電池モジュール1を平型の屋根60上に複数配置した状態を示す。
太陽電池モジュール1は、屋根60上に一面に配置されており、各太陽電池モジュール1は、その棟側の上端部が、軒側の下端部よりも持ち上がった形で取り付けられている。
Hereinafter, an example of a solar cell module to which the present invention is applied will be described with reference to the drawings.
FIG. 1 shows a state in which a plurality of solar cell modules 1 according to the present embodiment are arranged on a flat roof 60.
The solar cell module 1 is arranged on one surface on the roof 60, and each solar cell module 1 is attached such that the upper end portion on the ridge side is raised from the lower end portion on the eave side.
太陽電池モジュール1を取り付ける屋根上などには、図5に示すように固定金具3により屋根60上に固定された縦材2により屋根60上に固定される。
固定金具3は、図6に示すように、ねじにより屋根60上の傾斜面に沿って所定の間隔を置いて一列に取り付けられている。固定金具3は、一枚の板を折り曲げるようにして、左右に形成された取付部3aと、この取付部3aから左右に盛り上がるようにようにして形成された縦材保持部3bと、縦材保持部3bにより形成された溝3cと、縦材保持部上端から溝3cの開口部の内側に向かって突出した係合部3dとを有しており、その上端部には開口が形成されている。溝3cは、太陽電池モジュール1の取付面である屋根60の傾斜方向とは略直交する方向に形成された横溝となっている。この溝3cの幅は、縦材2を固定するためのボルト30のねじ部分30bの径よりも大きく、かつ、ボルト30の大径部をなす頭部30aの径よりも小さくなっている。これにより、ボルト30が、その頭部30aを溝3cの側面の開口からスライドされて固定金具3に挿入して取付けられることにより、ボルト30のねじ部分30bが固定金具3上から突出した状態で、溝3cに沿ってスライドして動くようになる。この際、頭部30aは、係合部3dに引っ掛かるため、溝3cからは外れず、ねじ部30bだけが固定金具3から突出した状態となる。そして、この状態で、ねじ部分30bを縦材2の長穴22に嵌めて、突出したねじ部分にナットを嵌めて縦材2を固定することができる。
On the roof to which the solar cell module 1 is attached, as shown in FIG. 5, the solar cell module 1 is fixed on the roof 60 by the vertical member 2 fixed on the roof 60 by the fixing bracket 3.
As shown in FIG. 6, the fixtures 3 are attached in a row at predetermined intervals along the inclined surface on the roof 60 by screws. The fixing bracket 3 includes a mounting portion 3a formed on the left and right as a single plate is bent, a vertical member holding portion 3b formed so as to rise from the mounting portion 3a to the left and right, and a vertical member. It has a groove 3c formed by the holding portion 3b and an engaging portion 3d protruding from the upper end of the vertical material holding portion toward the inside of the opening of the groove 3c, and an opening is formed at the upper end portion. Yes. The groove 3 c is a horizontal groove formed in a direction substantially orthogonal to the inclination direction of the roof 60 that is the mounting surface of the solar cell module 1. The width of the groove 3 c is larger than the diameter of the screw portion 30 b of the bolt 30 for fixing the vertical member 2 and smaller than the diameter of the head portion 30 a forming the large diameter portion of the bolt 30. Thereby, the bolt 30 is slid from the opening on the side surface of the groove 3c and inserted into the fixing bracket 3 so that the screw portion 30b of the bolt 30 protrudes from above the fixing bracket 3. Then, it slides and moves along the groove 3c. At this time, the head portion 30a is caught by the engaging portion 3d, so that it does not come off from the groove 3c, and only the screw portion 30b protrudes from the fixing bracket 3. In this state, the threaded portion 30b can be fitted into the elongated hole 22 of the longitudinal member 2, and a nut can be fitted to the protruding threaded portion to fix the longitudinal member 2.
縦材2は、図7に示すように、亜鉛めっき鋼板などの部材を折り曲げるようにして形成されており、その下端部が開口した横長の中空の四角柱状に形成されている。縦材2の上端部には、係合部21と、長孔22が形成されている。係合部21は、縦材2上に、所定の間隔(太陽電池モジュール1の縦幅から接合部分11gの幅を引いた長さの間隔)をおいて設けられている。これにより、係合部21に太陽電池モジュール1が取り付けられた場合、上下に隣り合う太陽電池モジュール1の上側の太陽電池モジュール1の接合部11gと下側の太陽電池モジュール1のモジュール取付部11bとが重なるようになっている。この係合部21は、縦材2の上端部を切り起こして上側に突出させて形成されている。したがって、係合部21は、縦材2の上端面から立ち上がって上側(棟側)に開口し、縦材2上面との間にわずかな隙間ができるようになっている。
長孔22は、係合部21、21間に設けられ、この長孔22には、固定金具3からのボルト30が通され、ナットにより締められることで、縦材2が固定金具3上に固定されるようになっている。
これらの縦材2は、複数連結させることで、屋根60の大きさや形に合わせて一面に配置され、平行に設けられた2本の縦材で太陽電池モジュール1を支える。
縦材2の下端部上面には、縦材2の端縁部をカバーするスタートカバー4を取り付けるためのねじ穴23が形成されている。スタートカバー4により、太陽電池モジュール1の下に風が入り、その風圧で太陽電池モジュール1が外れないようにすることができる。
As shown in FIG. 7, the vertical member 2 is formed by bending a member such as a galvanized steel plate, and is formed in a horizontally long hollow rectangular column shape having an open lower end. An engagement portion 21 and a long hole 22 are formed at the upper end portion of the vertical member 2. The engaging portions 21 are provided on the vertical member 2 at a predetermined interval (a length interval obtained by subtracting the width of the joint portion 11 g from the vertical width of the solar cell module 1). Thereby, when the solar cell module 1 is attached to the engaging portion 21, the joint portion 11g of the solar cell module 1 on the upper side of the solar cell module 1 adjacent to the upper and lower sides and the module attachment portion 11b of the solar cell module 1 on the lower side. And overlap. The engaging portion 21 is formed by cutting and raising the upper end portion of the longitudinal member 2 so as to protrude upward. Therefore, the engaging portion 21 rises from the upper end surface of the longitudinal member 2 and opens upward (toward the ridge side), so that a slight gap is formed between the engaging portion 21 and the upper surface of the longitudinal member 2.
The long hole 22 is provided between the engaging portions 21, 21, and the bolt 30 from the fixing bracket 3 is passed through the long hole 22 and is tightened by a nut, so that the vertical member 2 is placed on the fixing bracket 3. It is supposed to be fixed.
By connecting a plurality of these vertical members 2, the solar cell module 1 is supported by two vertical members that are arranged on one surface according to the size and shape of the roof 60 and provided in parallel.
A screw hole 23 for attaching the start cover 4 that covers the edge of the vertical member 2 is formed on the upper surface of the lower end of the vertical member 2. The start cover 4 can prevent wind from entering the solar cell module 1 and prevent the solar cell module 1 from being detached by the wind pressure.
太陽電池モジュール1は、図2、図4に示すように、中空枠状のフレーム11と、このフレーム11の中空枠内に取り付けられた太陽電池基板12を有している。

また、柱部11cには、図2(c)に示すように、穴11Mが2つ形成されている。この穴11Mは、フレーム11の幅方向の中心Cを基準として対称な位置、すなわち、それぞれ中心Cから距離Lおいた位置に設けられている。この穴11Mは、この太陽電池基板12により発電された電力を外部に送電するためのケーブル14を引き出すための穴である。
なお、この実施例では、穴11Mの位置が、穴11Hの位置に対応するようになっているが、必ずしもケーブル14を引き出すための穴11Mの位置は穴11Hの位置と対応させる必要はない。
係合部11dは、柱部11cからフレーム内側向かって延び出して形成されることで、太陽電池モジュール1を取り付けた状態で軒側に開口して形成されている。太陽電池モジュール1が縦材2に取り付けられる際、この係合部11dは、縦材2の係合部21に係合するようになっている。
基底部11eは、柱部11cからフレーム外側にそれぞれ向かって延びており、この基底部11eを押さえ金具により押さえることで、太陽電池モジュール1の上端部を縦材2上に固定するようになっている。

The holes 11M are provided at symmetrical positions with respect to the center C in the width direction of the frame 11, that is, at positions spaced from the center C by a distance L. This hole 11M is a hole for pulling out the cable 14 for transmitting the electric power generated by the solar cell substrate 12 to the outside.
In this embodiment, the position of the hole 11M corresponds to the position of the hole 11H, but the position of the hole 11M for pulling out the cable 14 does not necessarily correspond to the position of the hole 11H.
11 d of engaging parts are extended and formed toward the inner side of a flame | frame from the pillar part 11c, and are opened and formed in the eaves side in the state which attached the solar cell module 1. As shown in FIG. When the solar cell module 1 is attached to the longitudinal member 2, the engaging portion 11 d is engaged with the engaging portion 21 of the longitudinal member 2.

次に、本発明にかかる太陽電池モジュール1の取り付け方法の一例について図を参照して説明する。
本例は、平型屋根60に対して太陽電池ジュール1を取り付ける場合の例である。
まず、図6(a)に示すようにまず、屋根60上に固定金具3を取り付ける。
この場合、屋根60の垂木上に、固定金具3のビス穴を位置決めして、ドリルで屋根60上に穴を開ける。
この際、穴から雨水が浸入することを防ぐため、穴を開けた後に、ブチルゴム等の防水シートを固定金具3と屋根面の間に挟み、図6(a)に示すように、固定金具3のビス穴からビスを打ち込んで屋根60上に固定し、固定金具3、および、ブチルゴム等の防水シートの周囲に防水剤Sを塗布する。
Next, an example of a method for attaching the solar cell module 1 according to the present invention will be described with reference to the drawings.
In this example, the solar cell module 1 is attached to the flat roof 60.
First, as shown in FIG. 6A, first, the fixing bracket 3 is attached on the roof 60.
In this case, the screw hole of the fixture 3 is positioned on the rafter of the roof 60, and a hole is made on the roof 60 with a drill.
At this time, in order to prevent rainwater from entering through the hole, a waterproof sheet such as butyl rubber is sandwiched between the fixing metal 3 and the roof surface after the hole is formed, and as shown in FIG. A screw is driven in from the screw hole and fixed on the roof 60, and a waterproofing agent S is applied around the fixing bracket 3 and a waterproof sheet such as butyl rubber.
固定金具3の取り付が完了したところで、図6(b)に示すように、ボルト30の頭部分30aを、溝3cの側面の開口からスライドされて固定金具3に挿入して取付ける。
これにより、ボルト30は、溝3cに沿ってスライドして動くことができるが、その頭部30aは係合部30dにより引っ掛かるため溝3cからは外れず、ねじ部30bだけが固定金具3から突出した状態となる。
この状態で、図7に示すように、ねじ部分30bに、縦材2の長穴に嵌めて、突出したねじ部分30bにナットを嵌めて縦材2を固定する。この際、縦材2を取り付けた状態で、ナットを緩めてボルト30を溝3cに沿って移動させることで、縦材2の横方向の位置を調整することができる。また、縦材2の長孔に沿って、ねじ部分30bをスライドさせることで、縦方向の調整をすることができる。これにより、太陽電池モジュール1の取付位置を縦横で調整することができる。そして、取付位置が決まったところで、ナットをしっかり締めることで、縦材2を固定することができる。
When the mounting of the fixing bracket 3 is completed, the head portion 30a of the bolt 30 is slid from the opening on the side surface of the groove 3c and inserted into the fixing bracket 3 as shown in FIG. 6B.
Thereby, the bolt 30 can slide and move along the groove 3c, but its head 30a is hooked by the engaging portion 30d and thus does not come off from the groove 3c, and only the screw portion 30b protrudes from the fixing bracket 3. It will be in the state.
In this state, as shown in FIG. 7, the longitudinal member 2 is fixed by fitting the screw portion 30b into the elongated hole of the longitudinal member 2 and fitting the nut to the protruding screw portion 30b. At this time, the position of the vertical member 2 in the horizontal direction can be adjusted by loosening the nut and moving the bolt 30 along the groove 3c with the vertical member 2 attached. Further, the screw portion 30b is slid along the long hole of the vertical member 2, whereby the vertical adjustment can be performed. Thereby, the attachment position of the solar cell module 1 can be adjusted vertically and horizontally. And when the attachment position is determined, the vertical member 2 can be fixed by firmly tightening the nut.
また、この縦材2を屋根60の幅に合わせて一直線に配置するためには、縦材2を複数繋いで固定することで、屋根60の広さに応じて一直線状に取り付けることができる。これにより、図5に示すように屋根60上には、複数条の縦材2がそれぞれ平行に取り付けられた状態となる。
また、最も軒側の縦材2の下端部には、図8に示すようにスタートカバー4を縦材2上にねじ止めして取り付ける。
Further, in order to arrange the vertical members 2 in a straight line in accordance with the width of the roof 60, the vertical members 2 can be attached in a straight line according to the width of the roof 60 by fixing a plurality of the vertical members 2. Thereby, as shown in FIG. 5, on the roof 60, it will be in the state by which the multiple vertical material 2 was each attached in parallel.
Further, as shown in FIG. 8, the start cover 4 is screwed onto the vertical member 2 and attached to the lower end portion of the vertical member 2 closest to the eaves.
縦材2及びスタートカバー4の取り付けが完了すると、軒側から順に太陽電池モジュール1を取り付けていく。
この場合、図9に示すように、太陽電池モジュール1を縦材2上に仮置し、その状態で太陽電池モジュール1をわずかに上側にずらすことで、係合部11eを縦材2の係合部21に引っ掛ける。
そして、太陽電池モジュール1の基底部11eを押さえ金具で押さえて、この押さえ金具をねじ止めすることで太陽電池モジュール1を取り付ける。
When the attachment of the vertical member 2 and the start cover 4 is completed, the solar cell modules 1 are attached in order from the eaves side.
In this case, as shown in FIG. 9, the solar cell module 1 is temporarily placed on the vertical member 2, and in this state, the solar cell module 1 is slightly shifted upward, so that the engaging portion 11 e is engaged with the vertical member 2. Hang on the joint 21.
And the solar cell module 1 is attached by hold | suppressing the base part 11e of the solar cell module 1 with a pressing metal fitting, and screwing this pressing metal fitting.
また、この際、穴11Mからケーブル14を引き出し、左右に隣り合う太陽電池モジュール1を直列に接続する。例えば、+側のケーブル14を左隣の太陽電池モジュール1に接続し、−側のケーブル14を右隣の太陽電池モジュール1に接続していく。そして、最終端の太陽電池モジュール1のケーブル14を、図示しない集電ケーブルを介して接続箱へ接続することで、屋根全体の太陽電池パネルにより発電した電力を送電することができる。   At this time, the cable 14 is pulled out from the hole 11M, and the solar cell modules 1 adjacent to the left and right are connected in series. For example, the + side cable 14 is connected to the solar cell module 1 on the left side, and the − side cable 14 is connected to the solar cell module 1 on the right side. And the electric power generated with the solar cell panel of the whole roof can be transmitted by connecting the cable 14 of the solar cell module 1 of the last end to a connection box via the current collection cable which is not illustrated.
この状態からさらに棟側に向かって上下に隣り合う太陽電池モジュール1を連結して取り付けることにより、屋根全体に太陽電池モジュール1を固定することができる。   From this state, the solar cell modules 1 can be fixed to the entire roof by connecting and attaching the solar cell modules 1 that are vertically adjacent to each other toward the building.
このように、縦材2を固定金具3に固定する際、縦材2を取り付けた状態で、ナットを緩めてボルト30を溝3cに沿って移動させることで、縦材2の横方向の位置を調整することができる。また、縦材2の長孔に沿って、ねじ部分30bをスライドさせることで、傾斜方向(縦方向)の調整をすることができる。これにより、太陽電池モジュール1の取付位置を縦横で調整して、取り付けをすることができるため、縦材2の取付精度を良くすることができる。   As described above, when the vertical member 2 is fixed to the fixing metal 3, the nut 30 is loosened and the bolt 30 is moved along the groove 3c with the vertical member 2 attached. Can be adjusted. Moreover, the slanting direction (longitudinal direction) can be adjusted by sliding the screw portion 30b along the long hole of the longitudinal member 2. Thereby, since the attachment position of the solar cell module 1 can be adjusted vertically and horizontally and can be attached, the attachment accuracy of the vertical member 2 can be improved.
