Description
本発明は、太陽光発電パネルを太陽光発電パネル設置用架台に取り付ける際に、太陽光発電パネルと太陽光発電パネル設置用架台との間に介在させて用いられる連結金具に関する。
The present invention relates to a connecting metal fitting used by interposing between a photovoltaic power generation panel and a photovoltaic power generation panel installation mount when the photovoltaic power generation panel is attached to the photovoltaic power generation panel installation mount.
多くの太陽光発電パネルは、複数枚配列したセルを樹脂や強化ガラスなどで挟み、外周を金属製のフレーム枠で補強した構造となっており、地盤に打設された支持杭の上部に井桁状に組まれた桟材を連結した構造からなる太陽光発電パネル設置用架台に取り付けて使用される。一般にフレーム枠の裏側（セルが配列されている集光面の逆側）は、安定的に架台の桟材上に載置できるように内側に向かってフランジを有するように形成されている。
Many photovoltaic power generation panels have a structure in which multiple cells arranged are sandwiched between resin or tempered glass, and the outer circumference is reinforced with a metal frame, and the girder is placed on top of the support piles placed in the ground. It is used by attaching it to a stand for installing a photovoltaic power generation panel, which has a structure in which crosspieces assembled in a shape are connected. Generally, the back side of the frame (the opposite side of the light collecting surface on which the cells are arranged) is formed so as to have a flange inward so that the frame can be stably placed on the crosspiece of the gantry.
このような太陽光発電パネルを太陽光発電パネル設置用架台に取り付ける際には、例えば特許文献１に開示されているように、太陽光発電パネルのフレーム枠に設けられた取付孔に合わせたボルト挿通孔を架台の桟材にあけ、ボルトを取付孔及びボルト挿通孔に通してナットを螺合させて締め付けることで、太陽光発電パネルを太陽光発電パネル設置用架台に固定する方式が一般的に用いられている。
When such a photovoltaic power generation panel is attached to a frame for installing a photovoltaic power generation panel, for example, as disclosed in Patent Document 1, bolts matching the mounting holes provided in the frame frame of the photovoltaic power generation panel. It is common to fix the photovoltaic power generation panel to the photovoltaic power generation panel installation mount by making an insertion hole in the crosspiece of the gantry, passing the bolt through the mounting hole and the bolt insertion hole, and screwing and tightening the nut. It is used in.
破損や故障等により太陽光発電パネルの交換が必要になった場合、図７に示すように、交換対象となる太陽光発電パネルを架台から取り外して、新たな太陽光発電パネルを上述のような固定方法で再び取り付けることになる。しかしながら、交換対象となった太陽光発電パネルと新しい太陽光発電パネルの型番が異なると取付孔の位置が異なる場合があり、そのような場合には太陽光発電パネル設置用架台のボルト挿通孔と交換する新しい太陽光発電パネルの取付孔の位置が合わないという問題が生じる。新しい太陽光発電パネルの取付孔の位置に合わせて太陽光発電パネル設置用架台側に新たなボルト挿通孔をあけることも考えられるが、すでに現場に設置されている架台に対してそのような作業を行うことは大変非効率であり、また必ずしも新しい太陽光発電パネルの取付孔に対応する位置に架台の桟材が存在するとは限らない。
When it becomes necessary to replace the photovoltaic power generation panel due to damage or failure, as shown in FIG. 7, the photovoltaic power generation panel to be replaced is removed from the gantry, and a new photovoltaic power generation panel is installed as described above. It will be reattached by the fixing method. However, if the model number of the photovoltaic power generation panel to be replaced is different from that of the new photovoltaic power generation panel, the position of the mounting hole may be different. There is a problem that the mounting holes of the new PV panel to be replaced are not aligned. It is conceivable to make a new bolt insertion hole on the side of the pedestal for installing the photovoltaic power generation panel according to the position of the mounting hole of the new photovoltaic power generation panel, but such work is done for the pedestal already installed at the site. It is very inefficient to do this, and the pedestal crosspiece is not always present at the position corresponding to the mounting hole of the new PV panel.
本発明は上述のような事情に基づいてなされたものであり、太陽光発電パネル側の取付孔と太陽光発電パネル設置用架台側のボルト挿通孔との位置関係によらず、太陽光発電パネルを太陽光発電パネル設置用架台に取り付けることを可能にする連結金具の提供を目的とする。

本実施形態に係る連結金具１は、やや厚みのある平面視略矩形状のプレート形状を有しており、太陽光発電パネルを太陽光発電パネル設置用架台に取り付ける際に、太陽光発電パネルと太陽光発電パネル設置用架台との間に介在させ、六角ボルトを用いて太陽光発電パネル及び太陽光発電パネル設置用架台のそれぞれに固定される。連結金具１は、図１（ａ）及び（ｂ）に示すように、反対方向に開口する二つの取付溝（第１取付溝１１ａ、第２取付溝１１ｂ）を備える。なお、本実施形態の説明においては、図１に示すように、連結金具１の取付溝１１ａ、１１ｂが形成されている方向をｘ方向、取付溝１１ａ、１１ｂと直交する方向をｙ方向、厚み方向をｚ方向と呼ぶことがある。
The connecting metal fitting 1 according to the present embodiment has a slightly thick plate shape having a substantially rectangular shape in a plan view, and when the photovoltaic power generation panel is attached to the stand for installing the photovoltaic power generation panel, it is combined with the photovoltaic power generation panel. It is interposed between the pedestal for installing the photovoltaic power generation panel and fixed to each of the photovoltaic power generation panel and the pedestal for installing the photovoltaic power generation panel using hexagon bolts. As shown in FIGS. 1A and 1B, the connecting metal fitting 1 includes two mounting grooves (first mounting groove 11a and second mounting groove 11b) that open in opposite directions. In the description of the present embodiment, as shown in FIG. 1, the direction in which the mounting grooves 11a and 11b of the connecting metal fitting 1 are formed is the x direction, the direction orthogonal to the mounting grooves 11a and 11b is the y direction, and the thickness. The direction may be referred to as the z direction.
連結金具１の第１取付溝１１ａ及び第２取付溝１１ｂは、互いに反対方向を向いて開口するように形成されており、連結金具１を太陽光発電パネルと太陽光発電パネル設置用架台との間に介在させるときに、第１取付溝１１ａが太陽光発電パネル側に向いている場合には第２取付溝１１ｂが太陽光発電パネル設置用架台側を向くように、第２取付溝１１ｂが太陽光発電パネル側に向いている場合には第１取付溝１１ａが太陽光発電パネル設置用架台側を向くように構成されている。また、第１取付溝１１ａ及び第２取付溝１１ｂはそれぞれ直線状に、かつ両者が平行になるように形成されており、連結金具１において第１取付溝１１ａ及び第２取付溝１１ｂは平面視（ｘｙ平面視）で重ならないように配置されている。このように第１取付溝１１ａ及び第２取付溝１１ｂを形成することにより、第１取付溝１１ａ及び第２取付溝１１ｂが隣り合うように連結金具１を構成することが可能になり、連結金具１の厚み（ｚ方向の長さ）を抑えることができる。
The first mounting groove 11a and the second mounting groove 11b of the connecting metal fitting 1 are formed so as to open in opposite directions to each other, and the connecting metal fitting 1 is provided between the photovoltaic power generation panel and the stand for installing the photovoltaic power generation panel. When intervening between them, if the first mounting groove 11a faces the photovoltaic power generation panel side, the second mounting groove 11b faces the photovoltaic power generation panel installation mount side. When facing the photovoltaic power generation panel side, the first mounting groove 11a is configured to face the photovoltaic power generation panel installation stand side. Further, the first mounting groove 11a and the second mounting groove 11b are formed so as to be linear and parallel to each other, and the first mounting groove 11a and the second mounting groove 11b in the connecting metal fitting 1 are viewed in a plan view. They are arranged so as not to overlap in (xy plane view). By forming the first mounting groove 11a and the second mounting groove 11b in this way, it becomes possible to configure the connecting metal fitting 1 so that the first mounting groove 11a and the second mounting groove 11b are adjacent to each other, and the connecting metal fitting 1 can be configured. The thickness of 1 (length in the z direction) can be suppressed.
第１取付溝１１ａは、図１（ｂ）に示すように、底面部１１１ａと、底面部１１１ａの両端から対向するように延設される一対の側面部（第１側面部１１２ａ、第２側面部１１３ａ）と、一対の側面部１１２ａ、１１３ａのそれぞれの端部から底面部１１１ａと平行にかつ互いに近づく方向に延設される一対の天面部（第１天面部１１４ａ、第２天面部１１５ａ）とから構成される。また、第２取付溝１１ｂは、図１（ｂ）に示すように、底面部１１１ｂと、底面部１１１ｂの両端から対向するように延設される一対の側面部（第１側面部１１２ｂ、第２側面部１１３ｂ）と、一対の側面部１１２ｂ、１１３ｂのそれぞれの端部から底面部１１１ｂと平行にかつ互いに近づく方向に延設される一対の天面部（第１天面部１１４ｂ、第２天面部１１５ｂ）とから構成される。また、第１取付溝１１ａと第２取付溝１１ｂの長手方向（ｘ方向）の両端面は開放面となっている。本実施形態においては、第１取付溝１１ａと第２取付溝１１ｂとが（反対方向に開口しているものの）隣り合うように形成されているため、第１取付溝１１ａの第２側面部１１３ａは第２取付溝１１ｂの第２側面部１１３ｂとしても機能しており、第２取付溝１１ｂの第２側面部１１３ｂは第１取付溝１１ａの第２側面部１１３ａとして機能しているともいえる。
As shown in FIG. 1B, the first mounting groove 11a is a pair of side surface portions (first side surface portion 112a, second side surface) extending so as to face each other from both ends of the bottom surface portion 111a and the bottom surface portion 111a. A pair of top surface portions (first top surface portion 114a, second top surface portion 115a) extending in parallel with the bottom surface portion 111a and in a direction approaching each other from the respective end portions of the portion 113a) and the pair of side surface portions 112a and 113a. It is composed of and. Further, as shown in FIG. 1B, the second mounting groove 11b is a pair of side surface portions (first side surface portions 112b, first side surface portions 112b, 1st side surface portions 112b, which are extended so as to face each other from both ends of the bottom surface portion 111b and the bottom surface portion 111b. Two side surface portions 113b) and a pair of top surface portions (first top surface portion 114b, second top surface portion) extending from the respective ends of the pair of side surface portions 112b and 113b in parallel with the bottom surface portion 111b and in a direction approaching each other. It is composed of 115b). Further, both end surfaces of the first mounting groove 11a and the second mounting groove 11b in the longitudinal direction (x direction) are open surfaces. In the present embodiment, since the first mounting groove 11a and the second mounting groove 11b are formed so as to be adjacent to each other (although they are opened in opposite directions), the second side surface portion 113a of the first mounting groove 11a is formed. Also functions as the second side surface portion 113b of the second mounting groove 11b, and it can be said that the second side surface portion 113b of the second mounting groove 11b functions as the second side surface portion 113a of the first mounting groove 11a.
図１（ｂ）に示すように、第１取付溝１１ａ及び第２取付溝１１ｂはそれぞれが断面視Ｃ字形状を有し、連結金具１は全体として断面視Ｓ字形状を有する。（ここでいう断面とは第１取付溝１１ａ及び第２取付溝１１ｂに直交するｙｚ平面である。）本実施形態においては、第１取付溝１１ａ及び第２取付溝１１ｂが、開口方向が反対方向ではあるものの同じ形状・寸法を有しており、連結金具１は断面視点対称となる形状を有するように構成されている。連結金具１をこのように断面視点対称となる形状にすることにより、上下の区別なく連結金具１を用いることができるため、第１取付溝１１ａ及び第２取付溝１１ｂのどちらを太陽光発電パネル側に向けても使用でき、連結金具１使用の利便性が向上する。
As shown in FIG. 1 (b), the first mounting groove 11a and the second mounting groove 11b each have a C-shaped cross-sectional view, and the connecting metal fitting 1 has an S-shaped cross-sectional view as a whole. (The cross section referred to here is a yz plane orthogonal to the first mounting groove 11a and the second mounting groove 11b.) In the present embodiment, the first mounting groove 11a and the second mounting groove 11b have opposite opening directions. Although they are oriented in a direction, they have the same shape and dimensions, and the connecting metal fitting 1 is configured to have a shape that is symmetrical in terms of cross-sectional viewpoint. By forming the connecting metal fitting 1 into a shape symmetrical in terms of cross-sectional viewpoint, the connecting metal fitting 1 can be used regardless of the upper and lower sides. Therefore, either the first mounting groove 11a or the second mounting groove 11b is used as a photovoltaic power generation panel. It can also be used toward the side, improving the convenience of using the connecting bracket 1.
第１取付溝１１ａにおいては、第１側面部１１２ａ及び第２側面部１１３ａの離隔間隔（ｙ方向の間隔）が、連結金具１と太陽光発電パネル、連結金具１と太陽光発電パネル設置用架台の固定に用いる六角ボルト２の頭部２１の二面幅に等しいか又は大きく、かつ六角ボルト２の頭部２１の対角距離よりも小さく形成されており、第２取付溝１１ｂにおいても、第１側面部１１２ｂ及び第２側面部１１３ｂの離隔間隔（ｙ方向の間隔）が、連結金具１と太陽光発電パネル、連結金具１と太陽光発電パネル設置用架台の固定に用いる六角ボルト２の頭部２１の二面幅に等しいか又は大きく、かつ六角ボルト２の頭部２１の対角距離よりも小さく形成されている。このように第１取付溝１１ａ及び第２取付溝１１ｂを形成することにより、各取付溝の一対の側面部（第１側面部１１２ａ及び第２側面部１１３ａ、あるいは第１側面部１１２ｂ及び第２側面部１１３ｂ）が六角ボルト２の頭部２１を回転不能に保持することができるので、連結金具１を用いた太陽光発電パネルの太陽光発電パネル設置用架台への取付作業を安定的に行うことができるとともに、取付状態を安定させることができる。
In the first mounting groove 11a, the separation interval (interval in the y direction) between the first side surface portion 112a and the second side surface portion 113a is the connecting metal fitting 1 and the photovoltaic power generation panel, and the connecting bracket 1 and the photovoltaic power generation panel installation stand. It is formed to be equal to or larger than the width across flats of the head 21 of the hexagon bolt 2 used for fixing, and smaller than the diagonal distance of the head 21 of the hexagon bolt 2, and also in the second mounting groove 11b. The separation interval (interval in the y direction) between the 1 side surface portion 112b and the second side surface portion 113b is the head of the hexagon bolt 2 used for fixing the connecting bracket 1 and the photovoltaic power generation panel, and the connecting bracket 1 and the pedestal for installing the photovoltaic power generation panel. It is formed to be equal to or larger than the width across flats of the portion 21 and smaller than the diagonal distance of the head 21 of the hexagon bolt 2. By forming the first mounting groove 11a and the second mounting groove 11b in this way, a pair of side surface portions (first side surface portion 112a and second side surface portion 113a, or first side surface portion 112b and second) of each mounting groove are formed. Since the side surface portion 113b) can hold the head portion 21 of the hexagon bolt 2 non-rotatably, the work of stably attaching the photovoltaic power generation panel to the photovoltaic power generation panel installation stand using the connecting metal fitting 1 is performed. At the same time, the mounting state can be stabilized.
また、第１取付溝１１ａにおいては、第１天面部１１４ａ及び第２天面部１１５ａの離隔間隔（ｙ方向の間隔）が、六角ボルト２の軸部２２の軸径に等しいか又は大きく、かつ六角ボルト２の頭部２１の二面幅よりも小さく形成されており、第２取付溝１１ｂにおいても、第１天面部１１４ｂ及び第２天面部１１５ｂの離隔間隔（ｙ方向の間隔）が、六角ボルト２の軸部２２の軸径に等しいか又は大きく、かつ六角ボルト２の頭部２１の二面幅よりも小さく形成されている。このように第１取付溝１１ａ及び第２取付溝１１ｂを形成することにより、各取付溝（第１取付溝１１ａ及び第２取付溝１１ｂ）に嵌合させた六角ボルト２の頭部２１が一対の天面部（第１天面部１１４ａ及び第２天面部１１５ａ、あるいは第１天面部１１４ｂ及び第２天面部１１５ｂ）の間（すなわち第１取付溝１１ａ及び第２取付溝１１ｂの開口）から抜けないように保持することができるので、連結金具１を用いた太陽光発電パネルの太陽光発電パネル設置用架台への取付作業を安定的に行うことができるとともに、取付状態を安定させることができる。
Further, in the first mounting groove 11a, the separation interval (interval in the y direction) between the first top surface portion 114a and the second top surface portion 115a is equal to or larger than the shaft diameter of the shaft portion 22 of the hexagon bolt 2, and is hexagonal. The bolt 2 is formed to be smaller than the width across flats of the head 21, and even in the second mounting groove 11b, the separation interval (interval in the y direction) between the first top surface portion 114b and the second top surface portion 115b is a hexagon bolt. It is formed to be equal to or larger than the shaft diameter of the shaft portion 22 of 2 and smaller than the width across flats of the head 21 of the hexagon bolt 2. By forming the first mounting groove 11a and the second mounting groove 11b in this way, a pair of heads 21 of the hexagon bolt 2 fitted in each mounting groove (first mounting groove 11a and second mounting groove 11b) are paired. Can not come out from between the top surface portions (first top surface portion 114a and second top surface portion 115a, or first top surface portion 114b and second top surface portion 115b) (that is, openings of the first mounting groove 11a and the second mounting groove 11b). Since the solar power generation panel can be held in such a manner, the work of mounting the solar power generation panel on the solar power generation panel installation stand using the connecting metal fitting 1 can be stably performed, and the mounting state can be stabilized.

図４（ａ）に示すように、新たに取り付けられる太陽光発電パネル３（新パネル３）のフレーム３１には、太陽光発電パネル設置用架台４に取り付けるために用いられる取付孔３２が４箇所設けられている。一方、図４（ｂ）に示すように、交換のために取り外された太陽光発電パネル３Ａ（旧パネル３Ａ）のフレーム３１Ａにも、太陽光発電パネル設置用架台４に取り付けるために用いられる取付孔３２Ａが４箇所設けられているが、型番の違いにより、新パネル３に設けられている取付孔３２の位置と旧パネル３Ａに設けられている取付孔３２Ａの位置とにずれが発生してしまっている。
As shown in FIG. 4A, the frame 31 of the newly mounted photovoltaic power generation panel 3 (new panel 3) has four mounting holes 32 used for mounting on the pedestal 4 for installing the photovoltaic power generation panel. It is provided. On the other hand, as shown in FIG. 4 (b), the frame 31A of the photovoltaic power generation panel 3A (former panel 3A) removed for replacement is also attached to the frame 31A for mounting the photovoltaic power generation panel. There are four holes 32A, but due to the difference in model number, the position of the mounting hole 32 provided in the new panel 3 and the position of the mounting hole 32A provided in the old panel 3A are misaligned. It's closed.
図５には、太陽光発電パネル設置用架台４から旧パネル３Ａを取り外した状態が示されており、太陽光発電パネル設置用架台４の桟材４１にはボルト挿通孔４２が４箇所設けられている。この４箇所のボルト挿通孔４２の位置は、元々取り付けられていた旧パネル３Ａの取付孔３２Ａに対応した位置になっているため、太陽光発電パネル設置用架台４に直接新パネル３を載置し、取付孔３２とボルト挿通孔４２とを用いて六角ボルト２及び六角ナット８で固定することはできない。
FIG. 5 shows a state in which the old panel 3A is removed from the pedestal 4 for installing the photovoltaic power generation panel, and the crosspiece 41 of the pedestal 4 for installing the photovoltaic power generation panel is provided with four bolt insertion holes 42. ing. Since the positions of these four bolt insertion holes 42 correspond to the mounting holes 32A of the old panel 3A that was originally mounted, the new panel 3 is directly mounted on the pedestal 4 for installing the photovoltaic power generation panel. However, it cannot be fixed with the hexagon bolt 2 and the hexagon nut 8 by using the mounting hole 32 and the bolt insertion hole 42.
そこで、新パネル３と太陽光発電パネル設置用架台４との間に連結金具１を４つ挟み込み、連結金具１を介して新パネル３を太陽光発電パネル設置用架台４に取り付ける。具体的には、新パネル３の取付孔３２と太陽光発電パネル設置用架台４のボルト挿通孔４２との位置関係に応じて連結金具１をｘｙ平面上で回転させて調整し、連結金具１の第１取付溝１１ａに嵌合させた六角ボルト２が新パネル３の取付孔３２に対応する位置に来るようにし、連結金具１の第２取付溝１１ｂに嵌合させた六角ボルト２が太陽光発電パネル設置用架台４のボルト挿通孔４２に対応する位置に来るようにする。図６に、４つの連結金具１を用いて、新パネル３を太陽光発電パネル設置用架台３に取り付けた状態を示す。このように、太陽光発電パネル３側の取付孔３２と太陽光発電パネル設置用架台４側のボルト挿通孔４２との位置関係に応じて連結金具１を回転させて調整するだけで、太陽光発電パネル３側の取付孔３２が太陽光発電パネル設置用架台４側のボルト挿通孔４２の位置に対応する位置になくとも、連結金具１を介して太陽光発電パネル３を太陽光発電パネル設置用架台４に取り付けることが可能となる。
Therefore, four connecting brackets 1 are sandwiched between the new panel 3 and the pedestal 4 for installing the photovoltaic power generation panel, and the new panel 3 is attached to the pedestal 4 for installing the photovoltaic power generation panel via the connecting bracket 1. Specifically, the connecting metal fitting 1 is adjusted by rotating it on the xy plane according to the positional relationship between the mounting hole 32 of the new panel 3 and the bolt insertion hole 42 of the photovoltaic power generation panel installation stand 4, and the connecting metal fitting 1 is adjusted. The hexagon bolt 2 fitted in the first mounting groove 11a of the new panel 3 is located at a position corresponding to the mounting hole 32 of the new panel 3, and the hexagon bolt 2 fitted in the second mounting groove 11b of the connecting metal fitting 1 is the sun. Make sure that the position corresponds to the bolt insertion hole 42 of the stand 4 for installing the photovoltaic power generation panel. FIG. 6 shows a state in which the new panel 3 is attached to the stand 3 for installing the photovoltaic power generation panel by using the four connecting metal fittings 1. In this way, the solar power can be adjusted simply by rotating and adjusting the connecting metal fitting 1 according to the positional relationship between the mounting hole 32 on the photovoltaic power generation panel 3 side and the bolt insertion hole 42 on the photovoltaic power generation panel installation stand 4. Even if the mounting hole 32 on the power generation panel 3 side does not correspond to the position of the bolt insertion hole 42 on the solar power generation panel installation stand 4, the solar power generation panel 3 is installed via the connecting metal fitting 1. It can be attached to the stand 4.
