Description

本発明は、太陽電池モジュールを架台の縦桟上に固定するための金具と、これを用いた太陽電池モジュールの固定方法に関する。   The present invention relates to a metal fitting for fixing a solar cell module on a vertical rail of a gantry, and a method for fixing a solar cell module using the same.

太陽電池モジュールは、一般的に、矩形状の太陽電池パネルと、この太陽電池パネルの周縁を囲んでこれを保持するアルミニウム等の金属製の枠体とで構成される。このように構成された複数の太陽電池モジュールが、架台上に並べられて固定され、太陽電池装置が構成される。一般に、架台は、支柱上に横桟と縦桟を格子状に組んで構成される。太陽電池モジュールは、架台を構成する縦桟又は横桟上に固定金具を用いて固定される。ところで、太陽電池モジュールは、太陽電池の発電によって帯電した電荷をアースするために枠体が接地される。
枠体のアース接地と、架台の取り付け桟への固定とを同時に簡単、確実に行うことができる太陽電池パネル取り付け架台が特許文献１に提案されている。この太陽電池パネル取り付け架台においては、架台を構成する取り付け桟の上に下部固定金具を介して太陽電池モジュールが固定される。取り付け桟上には、相互間隔を置いて隣接配置される２つの太陽電池モジュールの端部の枠体が下部固定金具を介して載せられる。２つの太陽電池モジュールの枠体の上面には、両枠体間に跨がるよう上部固定金具が配置され、上部固定金具、下部固定金具及び取り付け桟の３者を貫通するボルトが装着される。上部固定金具に連続する、ねじ孔付きの下板が、補助孔を介して取り付け桟の下面側へ回し入れられ、そのねじ孔にボルトが螺合され、ボルトの締め付けによって、２つの太陽電池モジュールが同時に取り付け桟上に固定される。下部固定金具の表面には、環状突条が形成されており、これが２つの太陽電池モジュールの枠体の下面に食い込んで枠体と下部固定金具とが電気的に導通し、接地される。 The solar cell module is generally composed of a rectangular solar cell panel and a metal frame such as aluminum that surrounds and holds the periphery of the solar cell panel. A plurality of solar cell modules configured as described above are arranged and fixed on a gantry to constitute a solar cell device. In general, the gantry is configured by assembling a horizontal beam and a vertical beam in a grid pattern on a support column. The solar cell module is fixed on a vertical beam or a horizontal beam constituting the gantry using a fixing bracket. By the way, in the solar cell module, the frame body is grounded in order to ground the electric charge charged by the power generation of the solar cell.
Patent Document 1 proposes a solar cell panel mounting frame that can easily and reliably perform grounding of the frame body and fixing the frame to the mounting frame at the same time. In this solar cell panel mounting frame, the solar cell module is fixed on a mounting bar constituting the frame via a lower fixing bracket. On the mounting bar, the frame bodies at the ends of the two solar cell modules arranged adjacent to each other at a distance from each other are placed via the lower fixing bracket. On the upper surface of the frame of the two solar cell modules, an upper fixing bracket is disposed so as to straddle between the two frames, and a bolt that penetrates the upper fixing bracket, the lower fixing bracket, and the mounting bar is attached. . A lower plate with a screw hole that is continuous with the upper fixing bracket is turned into the lower surface side of the mounting bar via the auxiliary hole, and a bolt is screwed into the screw hole. Are fixed on the mounting bar at the same time. An annular protrusion is formed on the surface of the lower fixing bracket, which bites into the lower surfaces of the frames of the two solar cell modules, and the frame and the lower fixing bracket are electrically connected to each other and grounded.

上記従来の太陽電池モジュールの取り付け架台は、特殊形状の上部固定金具及び取り付け桟を用いるもので、製作に比較的大きなコストがかかる。これを用いずに、通常のボルト、ナットを用いる場合には、取り付け桟の下側からナットを螺合させる必要があるが、この場合、取り付け桟上への太陽電池モジュールの位置決め、設置、固定金具とボルトの装着、取り付け桟の下側へ廻ってのナットの締め付けの作業が繁雑になる。
したがって本発明は、太陽電池モジュールを固定するためのナットの締め付け作業を架台の下側から行わなければならない場合に、架台上への太陽電池モジュールの位置決め、設置及び固定金具の装着を容易に行うことができる太陽電池モジュールの隣接端部固定金具と、これを用いた太陽電池モジュールの固定方法を提供することを目的としている。 The above-mentioned conventional solar cell module mounting frame uses a specially shaped upper fixing bracket and mounting bar, and is relatively expensive to manufacture. If normal bolts and nuts are used without this, it is necessary to screw the nuts from below the mounting rail. In this case, the solar cell module is positioned, installed, and fixed on the mounting rail. Installation of metal fittings and bolts, and tightening nuts around the lower side of the mounting bar become complicated.
Therefore, according to the present invention, when the tightening operation of the nut for fixing the solar cell module must be performed from the lower side of the gantry, the solar cell module is easily positioned on the gantry, installed, and the fixing bracket is attached. It is an object of the present invention to provide an adjacent end fixing bracket for a solar cell module, and a solar cell module fixing method using the same.

As shown in FIG. 5, the vertical cell 31 is adjacent to the solar cell module according to the present invention. A plurality of solar cell modules 41 (41a, 41b) are fixed by using the end fixture 1. In the present specification and drawings, the extending direction of the vertical rail 31 is referred to as “vertical direction”, and the direction orthogonal thereto is referred to as “lateral direction” or “left-right direction”.

図６に示すように、縦桟３１は、平らな上面３２と、互いに平行な左右側面３３，３４と、複数のボルト挿通孔３５とを有する。ボルト挿通孔３５は、太陽電池モジュール４１の縦方向の寸法に対応する所定間隔で上下に貫通するように形成される。図示の実施形態において、縦桟３１は、チャンネル鋼材からなり、一端側から他端側（図１Ａ）おいて下端側から上端側）へ向かって高くなるように傾斜して配置されているが、これに限定されない。   As shown in FIG. 6, the vertical rail 31 has a flat upper surface 32, left and right side surfaces 33 and 34 parallel to each other, and a plurality of bolt insertion holes 35. The bolt insertion holes 35 are formed so as to penetrate vertically at a predetermined interval corresponding to the vertical dimension of the solar cell module 41. In the illustrated embodiment, the vertical beam 31 is made of channel steel, and is arranged to be inclined so as to increase from one end side to the other end side (FIG. 1A) from the lower end side to the upper end side.
