Description

本発明は、連結ボルトの軸部にスライド装着することができるボルト装着用スペーサーに係り、主に太陽電池モジュールをアレイ用架台に連結する連結ボルトに装着することで、太陽電池モジュールの連結作業等を容易にすることができるボルト装着用スペーサーに関する。   The present invention relates to a bolt mounting spacer that can be slidably mounted on a shaft portion of a connecting bolt, and is mainly connected to a connecting bolt that connects a solar cell module to an array frame, thereby connecting solar cell modules, etc. The present invention relates to a bolt mounting spacer that can facilitate the above.

ボルトの軸部にスライド装着することができるスペーサーとして、特許文献１に記載されているナット用スペーサーがある。このスペーサーは、側面が切り離されたリング形状を成し、内周面に雌ネジを設けると共に外周面に雄ネジを設けたものである。そして、ボルトの軸部に装着する際に、スペーサーのリング状側面を広げた状態で目的の位置までスライドさせてネジ山部分に雌ネジを嵌合して装着し、その後、スペーサー外周面の雄ネジに所定のナットをネジ止めして固定する。   As a spacer that can be slide-mounted on the shaft portion of the bolt, there is a nut spacer described in Patent Document 1. This spacer has a ring shape with side surfaces cut off, and is provided with a female screw on the inner peripheral surface and a male screw on the outer peripheral surface. Then, when attaching to the shaft of the bolt, slide the ring-shaped side surface of the spacer to the desired position, fit the female thread to the thread, and then attach the male screw on the outer peripheral surface of the spacer. Secure the screw with a specified nut.

一方、太陽電池モジュール１０は、複数枚つなぎ合わせた太陽電池用のセルをフレーム１１に装着したものである。このような太陽電池モジュール１０をアレイ用架台２０上にいくつも並べて連結することで、大きな電力を取り出せる太陽電池アレイが構築される（図７参照）。この太陽電池モジュール１０とアレイ用架台２０とを連結するには、アレイ用架台２０の主材２１上面に、太陽電池モジュール１０のフレーム１１を載置し、これらフレーム１１と主材２１とを連結ボルトＰにて連結する。   On the other hand, the solar cell module 10 is obtained by mounting a plurality of solar cell cells connected to a frame 11. A number of such solar cell modules 10 are connected side by side on the array mount 20 to construct a solar cell array that can extract a large amount of power (see FIG. 7). To connect the solar cell module 10 and the array mount 20, the frame 11 of the solar cell module 10 is placed on the upper surface of the main material 21 of the array mount 20, and the frame 11 and the main material 21 are connected. Connect with bolts P.

このとき、フレーム１１の下面には水抜き孔１２が設けられている。この水抜き孔１２は、フレーム１１内に水が溜まると寒冷時に凍結してフレーム１１を破損するおそれがあるので、これを防止するものである。そのため、フレーム１１と主材２１とを連結ボルトで連結する際に、この水抜き孔１２を塞がないようにして連結する必要がある。従来では、フレーム１１と主材２１との間に、連結ボルトを通すボルト挿通孔を設けた平鋼等のスペーサー１００を介することでフレーム１１の水抜き孔１２を塞がないようにしている（図８参照）。   At this time, a drain hole 12 is provided on the lower surface of the frame 11. The drain hole 12 prevents the water from being accumulated in the frame 11 because it may freeze in the cold and damage the frame 11. Therefore, when the frame 11 and the main material 21 are connected by the connecting bolt, it is necessary to connect the drain hole 12 so as not to be blocked. Conventionally, the drain hole 12 of the frame 11 is not blocked by a spacer 100 such as a flat steel provided with a bolt insertion hole through which the connecting bolt is passed between the frame 11 and the main material 21 ( (See FIG. 8).

また、従来の太陽電池モジュールにおいて、フレーム等の支持部材に水抜き孔を設けた例として特許文献２に示される太陽電池モジュールがある。この太陽電池モジュールではフレームの代わりに板状の金属屋根材を支持部材として使用するものである。このようにタイプの異なる太陽電池モジュールでも、支持部材となる金属屋根材に水抜き孔を設ける構成が記載されており、支持部材の水抜き孔の重要性が示されている。
実開平８‐１４２３６号公報 特開２０００‐１１４５７８号公報 Moreover, in the conventional solar cell module, there exists a solar cell module shown by patent document 2 as an example which provided the drainage hole in support members, such as a flame | frame. In this solar cell module, a plate-shaped metal roof material is used as a support member instead of a frame. As described above, even in solar cell modules of different types, a configuration in which a water drain hole is provided in a metal roof material serving as a support member is described, and the importance of the water drain hole of the support member is shown.

特許文献１に記載のスペーサーは、ボルトの軸部にスライド装着することは可能でも、このスペーサーを固定するために更にナットをネジ止めする必要がある。すなわち、このスペーサーの装着作業には、スペーサーのスライド装着と、ナットの固定といった二度の手間を要することになる。しかも、その１つはナットを回してネジ止めする作業であるから、スペーサーの装着作業に多くの手間と時間を要するものである。   Although the spacer described in Patent Document 1 can be slid on the shaft portion of the bolt, it is necessary to further screw a nut to fix the spacer. That is, the work of attaching the spacer requires two troubles such as the slide attachment of the spacer and the fixing of the nut. In addition, since one of them is an operation of turning the nut and screwing it, it takes a lot of labor and time to install the spacer.

一方、図８に示されるアレイ用架台２０に、従来のスペーサー１００を使用して太陽電池モジュール１０を連結するには多くの課題があった。第１の課題は、アレイ用架台２０の主材２１に傾斜がついているので、この主材２１上にスペーサー１００を仮置きできないことが原因になっている。従来の作業手順では、アレイ用架台２０が仮組みされた後、主材２１上で太陽電池モジュール１０をボルト止めする位置（通常１フレームにつき４箇所）に、ボルト挿通孔が開穿されたスペーサー１００を両面接着テープにて仮接着する。そして、連結ボルトＰをフレーム１１からスペーサー１００を介して主材２１に至るまで挿通し、ナットＱをネジ止めして固定していた。しかしながら、このような両面接着テープを使用した作業では、スペーサー１００の仮接着作業に多くの手間を要し、しかも、両面テープを使用する際に出るゴミ処理を行う作業が増える不都合もあった。   On the other hand, there are many problems in connecting the solar cell module 10 to the array platform 20 shown in FIG. 8 using the conventional spacer 100. The first problem is caused because the spacer 100 cannot be temporarily placed on the main material 21 because the main material 21 of the array mount 20 is inclined. In the conventional work procedure, after the array mount 20 is temporarily assembled, a spacer in which bolt insertion holes are opened at positions where the solar cell module 10 is bolted on the main material 21 (usually four locations per frame). 100 is temporarily bonded with a double-sided adhesive tape. Then, the connecting bolt P is inserted from the frame 11 through the spacer 100 to the main material 21, and the nut Q is fixed with screws. However, in the operation using such a double-sided adhesive tape, a lot of labor is required for the temporary bonding operation of the spacer 100, and there is also a problem that the work of performing dust disposal that occurs when using the double-sided tape is increased.

第２に、太陽電池モジュール１０の位置合わせ作業が困難になっていた。すなわち、主材２１上にスペーサー１００を仮接着した後は、この上に太陽電池モジュール１０のフレーム１１を載置する。このとき、太陽電池モジュール１０を主材２１上に載せ、片手で連結ボルトＰを持ち、反対の手で太陽電池モジュール１０を移動してボルト挿通孔の位置に合わせ、この位置が合ったところで連結ボルトＰを挿通するといった作業になる。ところが、この作業では、重い太陽電池モジュール１０を片手で持って調整する必要があるので、この位置合わせ作業が困難な作業になっている。   Secondly, the alignment operation of the solar cell module 10 has been difficult. That is, after the spacer 100 is temporarily bonded on the main material 21, the frame 11 of the solar cell module 10 is placed thereon. At this time, the solar cell module 10 is placed on the main material 21, the connection bolt P is held with one hand, the solar cell module 10 is moved with the other hand to the position of the bolt insertion hole, and the connection is made when this position is matched. The operation is such that the bolt P is inserted. However, in this work, since it is necessary to adjust the heavy solar cell module 10 with one hand, this positioning work is difficult.

また、別の位置合わせ作業として、両手で太陽電池モジュール１０の位置を調整することも可能である。この場合、フレーム１１のボルト挿通孔に予め連結ボルトＰを挿通しておき、この連結ボルトＰの下端部を、仮接着したスペーサー１００から主材２１のボルト挿通孔に挿入する作業になる。ところが、フレーム１１のボルト挿通孔に予め挿通した連結ボルトＰはフリーなので揺れ易く、連結ボルトＰの下端部の位置が定まりにくい状態にある。その上、スペーサー１００や主材２１のボルト挿通孔は、主材２１に沿って傾斜しているので、予めフレーム１１に挿通しておいた連結ボルトＰを、これらのボルト挿通孔に挿入することは極めて困難な作業にならざるを得ない。このように、太陽電池モジュール１０の位置合わせ作業が困難になっていた。   Further, as another positioning operation, the position of the solar cell module 10 can be adjusted with both hands. In this case, the connecting bolt P is inserted through the bolt insertion hole of the frame 11 in advance, and the lower end portion of the connecting bolt P is inserted into the bolt insertion hole of the main member 21 from the temporarily bonded spacer 100. However, since the connecting bolt P inserted in advance into the bolt insertion hole of the frame 11 is free, the connecting bolt P is easily shaken, and the position of the lower end portion of the connecting bolt P is difficult to be determined. In addition, since the spacer 100 and the bolt insertion holes of the main material 21 are inclined along the main material 21, the connecting bolts P that have been inserted through the frame 11 in advance are inserted into these bolt insertion holes. Must be an extremely difficult task. Thus, the alignment operation of the solar cell module 10 has been difficult.

第３は、メンテナンス上の課題である。この種の太陽電池アレイは、施工してから数年後に、点検や交換等で太陽電池モジュール１０をアレイ用架台２０から取外すことがある。このとき、主材２１から連結ボルトＰを抜き取ると、スペーサー１００を仮接着していた両面テープの接着力が既に消滅しているので、スペーサー１００が落下する危険がある。このように落下するスペーサー１００により、施設の塗膜防水処理を施した天井面や床面等を傷付けてしまうおそれがあり、また、作業者の安全性も問題になる。   The third is a maintenance problem. In this type of solar cell array, the solar cell module 10 may be removed from the array mount 20 by inspection or replacement several years after construction. At this time, if the connecting bolt P is removed from the main material 21, the adhesive force of the double-sided tape that has been temporarily bonded to the spacer 100 has already disappeared, and there is a risk that the spacer 100 will fall. Thus, the falling spacer 100 may damage the ceiling surface or floor surface of the facility that has been subjected to the waterproofing treatment of the coating film, and the safety of the operator also becomes a problem.

そこで本発明は上述の課題を解消すべく創出されたもので、簡単な操作で連結ボルトにスライド装着することができ、太陽電池モジュールをアレイ用架台に連結する連結ボルトに装着することで、太陽電池モジュールの連結作業や点検、交換作業においても安全に行うことが可能なボルト装着用スペーサーの提供を目的とするものである。   Therefore, the present invention has been created to solve the above-described problems, and can be slid and attached to the connecting bolt by a simple operation. By attaching the solar cell module to the connecting bolt for connecting to the array base, An object of the present invention is to provide a bolt mounting spacer that can be safely performed in battery module connection work, inspection, and replacement work.

上述の目的を達成すべく本発明における第１の手段は、連結ボルトＰで連結される一対の部材相互の間に配設され、該連結ボルトに仮止めするスペーサーであって、一方の部材に当接する当接基盤１と、該当接基盤１の盤面中央部から突出して他方の部材に当接する突出板２とが形成され、該突出板２の板面中央に連結ボルトＰを挿通する挿通孔３が開穿され、該挿通孔３の一側縁部から突設されて挿通孔３の上下いずれか一方に向いて傾斜する係止突起４を形成し、挿通孔３内の連結ボルトＰが係止突起４の傾斜に沿ったときにスペーサーが移動するように設け、挿通孔３内の連結ボルトＰが該挿通孔３に対して略直交する状態のときに挿通孔３の内側縁部が連結ボルトＰのネジ山Ｐ１に係止すると共に、係止突起４の先端４Ａが連結ボルトＰの側面を支持してスペーサーがネジ山Ｐ１に沿って回転するように設けたことにある。   In order to achieve the above-mentioned object, the first means in the present invention is a spacer which is disposed between a pair of members connected by a connecting bolt P and is temporarily fixed to the connecting bolt. An abutment base 1 that abuts and a protruding plate 2 that protrudes from the center of the board surface of the corresponding contact base 1 and abuts against the other member are formed, and an insertion hole through which the connecting bolt P is inserted in the center of the plate surface of the protruding plate 2 3 is opened to form a locking projection 4 that protrudes from one side edge of the insertion hole 3 and inclines toward one of the upper and lower sides of the insertion hole 3, and the connecting bolt P in the insertion hole 3 A spacer is provided so as to move along the inclination of the locking projection 4, and when the connecting bolt P in the insertion hole 3 is substantially orthogonal to the insertion hole 3, the inner edge of the insertion hole 3 is While locking to the thread P1 of the connecting bolt P, the tip 4A of the locking projection 4 is connected to the connecting bolt.

The inner edge portion is provided so as to be locked at two positions of the thread P1 of the connecting bolt P when it is substantially orthogonal to.

第３の手段は、前記突出板２の係止突起４において、該係止突起４の先端部を平面略Ｖ字形状に形成し、挿通孔３内の連結ボルトＰが該挿通孔３に対して略直交するときに該先端部が連結ボルトＰの側面二箇所を支持するように設けたものである。   The third means is that the locking projection 4 of the protruding plate 2 is formed with a substantially V-shaped front end portion of the locking projection 4, and the connecting bolt P in the insertion hole 3 is connected to the insertion hole 3. The tip portion is provided so as to support the two side surfaces of the connecting bolt P when substantially orthogonal.

第４の手段は、前記突出板２の挿通孔３において、挿通孔３の一側縁部から突設されて挿通孔３の上下いずれか一方に向いて傾斜する係止突起４を形成すると共に、
挿通孔３の他側縁部から突設されて該係止突起４の上下反対方向に傾斜する補助係止突起５を形成し、
挿通孔３内の連結ボルトＰが係止突起４と補助係止突起５との傾斜に沿ったときにスペーサーが移動するように設けると共に、挿通孔３内の連結ボルトＰが該挿通孔３に対して直交するときに係止突起４と補助係止突起５との先端４Ａ、５Ａが連結ボルトＰ側面のネジ山Ｐ１に係止するように設けたものである。 The fourth means forms a locking projection 4 which protrudes from one side edge of the insertion hole 3 and inclines toward one of the upper and lower sides of the insertion hole 3 in the insertion hole 3 of the protruding plate 2. ,
Auxiliary locking projections 5 that protrude from the other side edge of the insertion hole 3 and incline in the opposite direction to the locking projections 4 are formed.
A spacer is provided so that the spacer moves when the connecting bolt P in the insertion hole 3 follows the inclination of the locking protrusion 4 and the auxiliary locking protrusion 5, and the connecting bolt P in the insertion hole 3 is inserted into the insertion hole 3. The ends 4A and 5A of the locking projection 4 and the auxiliary locking projection 5 are provided so as to be locked to the thread P1 on the side surface of the connecting bolt P when they are orthogonal to each other.

第５の手段において、前記連結ボルトＰで連結される一対の部材は、太陽電池モジュール１０を支える略角筒状のフレーム１１と、水抜き孔１２が開穿されたフレーム１１の下面に連結するアレイ用架台２０の主材２１とし、これらフレーム１１と主材２１との間に前記スペーサーを配するように設けたことを課題解消のための手段とするものである。   In the fifth means, the pair of members connected by the connecting bolt P are connected to the substantially rectangular tube-shaped frame 11 that supports the solar cell module 10 and the lower surface of the frame 11 in which the drain hole 12 is opened. The main material 21 of the array mount 20 and the spacers are provided between the frame 11 and the main material 21 to solve the problem.

本発明の請求項１の如く、挿通孔３内の連結ボルトＰが係止突起４の傾斜に沿ったときにスペーサーが移動するように設け、挿通孔３内の連結ボルトＰが該挿通孔３に対して略直交する状態のときにスペーサーがネジ山Ｐ１に沿って回転するように設けたことにより連結ボルトＰへの装着作業がワンタッチで行うことが可能になった。この結果、ボルトを使用する連結手段においてスペーサーの装着作業を極めて容易に行うことができる。   As in claim 1 of the present invention, the spacer is moved so that the connecting bolt P in the insertion hole 3 moves along the inclination of the locking projection 4, and the connecting bolt P in the insertion hole 3 is connected to the insertion hole 3. By providing the spacer so as to rotate along the screw thread P1 when it is substantially orthogonal to the connecting bolt P, it is possible to perform the mounting operation to the connecting bolt P with one touch. As a result, the spacer mounting operation can be performed very easily in the connecting means using the bolts.

しかも、連結ボルトＰのネジ山Ｐ１に回転自在になっているので、連結ボルトＰが挿入されている部材側に本発明スペーサーを圧着することで、スペーサーのみならず、連結ボルトＰも安定した状態に固定することができる。   Moreover, since it is rotatable about the thread P1 of the connecting bolt P, the spacer according to the present invention is crimped to the member side where the connecting bolt P is inserted, so that not only the spacer but also the connecting bolt P is stable. Can be fixed to.

また、連結ボルトＰに沿って移動中のスペーサーから手を離した場合でも、スペーサーの自重で揺れ動き、係止突起４と挿通孔３とがネジ山Ｐ１に自然に係止するので、スペーサーの不意の落下を防止し、安全な使用が可能になる。   Further, even when the spacer is moved along the connecting bolt P, the spacer swings due to the weight of the spacer, and the locking protrusion 4 and the insertion hole 3 are naturally locked to the screw thread P1. Prevents falling and enables safe use.

請求項２の如く、前記係止突起４に相対する内側縁部を平面略Ｖ字形状に形成し、該内側縁部が連結ボルトＰの側面二箇所に係止するように設けたことで、連結ボルトＰのネジ山Ｐ１に挿通孔３の内側縁部が効率良く係止する。この結果、挿通孔３に対して略直交状態になっている連結ボルトＰを安定した状態に保持できる。   As in claim 2, the inner edge facing the locking protrusion 4 is formed in a substantially V-shaped plane, and the inner edge is provided so as to be locked at two positions on the side surface of the connecting bolt P. The inner edge of the insertion hole 3 is efficiently locked to the thread P1 of the connecting bolt P. As a result, the connecting bolt P that is substantially orthogonal to the insertion hole 3 can be held in a stable state.

請求項３の如く、係止突起４の先端部を平面略Ｖ字形状に形成し、該先端部が連結ボルトＰの側面二箇所に係止するように設けたことで、連結ボルトＰのネジ山Ｐ１に係止突起４の先端部が効率良く係止する。この結果、挿通孔３に対して略直交状態になっている連結ボルトＰを安定した状態に保持できる。   According to a third aspect of the present invention, the front end of the locking projection 4 is formed in a substantially V-shape and is provided so that the front end is locked at two positions on the side surface of the connection bolt P. The tip end portion of the locking projection 4 is efficiently locked to the peak P1. As a result, the connecting bolt P that is substantially orthogonal to the insertion hole 3 can be held in a stable state.

請求項４の如く、挿通孔３の上下いずれか一方に向いて傾斜する係止突起４と、該係止突起４の上下反対方向に傾斜する補助係止突起５を形成し、連結ボルトＰが該挿通孔３に対して直交するときに係止突起４と補助係止突起５との先端４Ａ、５Ａが連結ボルトＰ側面のネジ山Ｐ１に係止するように設けたことで、連結ボルトＰのネジ山Ｐ１に係止突起４と補助係止突起５との先端部が効率良く係止する。この結果、挿通孔３に対して略直交状態になっている連結ボルトＰを安定した状態に保持できる。   According to a fourth aspect of the present invention, there are formed the locking protrusions 4 inclined toward one of the upper and lower sides of the insertion hole 3 and the auxiliary locking protrusions 5 inclined in the opposite vertical direction of the locking protrusions 4. By providing the tips 4A and 5A of the locking projection 4 and the auxiliary locking projection 5 so as to be locked to the thread P1 on the side surface of the connecting bolt P when orthogonal to the insertion hole 3, the connecting bolt P The end portions of the locking projection 4 and the auxiliary locking projection 5 are efficiently locked to the thread P1. As a result, the connecting bolt P that is substantially orthogonal to the insertion hole 3 can be held in a stable state.

請求項５では、連結ボルトＰとナットＱで連結される一対の部材は、太陽電池モジュール１０を支える略角筒状のフレーム１１と、水抜き孔１２が開穿されたフレーム１１の下面に連結するアレイ用架台２０の主材２１とすることで、太陽電池モジュール１０とアレイ用架台２０との連結作業が極めて合理化される。たとえば、従来の両面接着テープを使用した作業のように、両面テープを張る作業や両面テープを使用する際に出るゴミ処理を行う作業が不要になった。   In claim 5, the pair of members connected by the connecting bolt P and the nut Q are connected to the substantially rectangular tube-shaped frame 11 that supports the solar cell module 10 and the lower surface of the frame 11 in which the drain hole 12 is opened. By using the main material 21 of the array mount 20 to be performed, the connection work between the solar cell module 10 and the array mount 20 is extremely rationalized. For example, the work of applying a double-sided tape or the treatment of dust generated when using a double-sided tape, such as the work of using a conventional double-sided adhesive tape, has become unnecessary.

また、両手で太陽電池モジュール１０の位置を調整する場合、フレーム１１のボルト挿通孔に予め連結ボルトＰを挿通しておき、この連結ボルトＰに本発明スペーサーを装着することで、連結ボルトＰの下端部を、主材２１のボルト挿通孔に容易に挿入することができる。   Moreover, when adjusting the position of the solar cell module 10 with both hands, the connection bolt P is previously inserted in the bolt insertion hole of the frame 11, and the spacer of the present invention is attached to the connection bolt P, so that the connection bolt P The lower end can be easily inserted into the bolt insertion hole of the main material 21.

更に、点検や交換等で太陽電池モジュール１０をアレイ用架台２０から取外す場合でも、主材２１上面から連結ボルトＰから本発明スペーサーが落下する危険がなくなり、施設の塗膜防水処理を施した天井面や床面等を傷付けてしまうおそれや、作業者の安全性の問題も解決した。   Furthermore, even when the solar cell module 10 is removed from the array mount 20 for inspection or replacement, there is no risk of the spacer of the present invention falling from the connecting bolt P from the upper surface of the main material 21, and the ceiling subjected to the waterproof coating treatment of the facility The problem of damaging the surfaces and floors and the safety issues of workers were also solved.

このように本発明によると、簡単な操作で連結ボルトにスライド装着することができ、太陽電池モジュールをアレイ用架台に連結する作業上の手間を軽減することが可能で、太陽電池モジュールの点検や交換作業においても安全に行うことができるなどといった種々の効果を奏するものである。   As described above, according to the present invention, it is possible to slide the mounting bolt to the connecting bolt with a simple operation, and it is possible to reduce the labor for connecting the solar cell module to the array mount. Various effects, such as being able to perform safely also in exchange work, are produced.

本発明の最良の形態は、連結ボルトに仮止めして該連結ボルトＰで連結される一対の部材相互の間に配設されるスペーサーを設ける。一方の部材に当接する当接基盤１と、該当接基盤１の板面中央部から突出して他方の部材に当接する突出板２とを一体に形成する。該突出板２の板面中央に連結ボルトＰを挿通する挿通孔３が開穿され、該挿通孔３の一側縁部から突設されて挿通孔３の上下いずれか一方に向いて傾斜する係止突起４を形成し、該挿通孔３内の連結ボルトＰが係止突起４の傾斜に沿ったときにスペーサーが移動するように設ける。
挿通孔３内の連結ボルトＰが該挿通孔３に対して略直交する状態のときに挿通孔３の内側縁部が連結ボルトＰ側面のネジ山Ｐ１に係止すると共に、係止突起４の先端４Ａが連結ボルトＰの側面を支持してスペーサーがネジ山Ｐ１に沿って回転するように設ける。

連結ボルトＰとナットＱで連結される一対の部材は、太陽電池モジュール１０を支える略角筒状のフレーム１１と、水抜き孔１２が開穿されたフレーム１１の下面に連結するアレイ用架台２０の主材２１とすることで当初の目的を達成するものである。 In the best mode of the present invention, a spacer is provided between a pair of members that are temporarily fixed to the connecting bolt and connected by the connecting bolt P. An abutment base 1 that abuts one member and a projecting plate 2 that projects from the center of the plate surface of the contact base 1 and abuts the other member are integrally formed. An insertion hole 3 through which the connecting bolt P is inserted is opened in the center of the plate surface of the protruding plate 2, and protrudes from one side edge portion of the insertion hole 3 so as to incline toward the upper or lower side of the insertion hole 3. The locking protrusion 4 is formed, and the spacer is moved so that the connecting bolt P in the insertion hole 3 moves along the inclination of the locking protrusion 4.
When the connecting bolt P in the insertion hole 3 is substantially orthogonal to the insertion hole 3, the inner edge of the insertion hole 3 is locked to the thread P1 on the side surface of the connecting bolt P, and the locking projection 4 The tip 4A supports the side surface of the connecting bolt P, and the spacer is provided so as to rotate along the thread P1.
The inner edge facing the locking projection 4 is formed in a substantially V-shaped plane, and the inner edge is connected to the connecting bolt P when the connecting bolt P in the insertion hole 3 is substantially orthogonal to the insertion hole 3. It is provided so as to be locked at two places on the side surface of P.
The front end portion of the locking projection 4 is formed in a substantially V shape in a plane, and when the connecting bolt P in the insertion hole 3 is substantially perpendicular to the insertion hole 3, the front end portion is a side surface of the connecting bolt P. It is provided so as to be locked in place.
The pair of members connected by the connecting bolts P and nuts Q are a substantially rectangular cylindrical frame 11 that supports the solar cell module 10 and an array mount 20 that is connected to the lower surface of the frame 11 in which the drain holes 12 are opened. By using the main material 21, the initial purpose is achieved.

以下、本発明の一実施例を説明する。本発明スペーサーは、連結ボルトＰで連結される一対の部材相互の間に配設され、該連結ボルトに仮止めするスペーサーである（図４参照）。更に本発明スペーサーは、太陽電池モジュール１０を支える略角筒状のフレーム１１と、アレイ用架台２０の主材２１との間に配設される（図７参照）。   An embodiment of the present invention will be described below. The spacer of the present invention is a spacer that is disposed between a pair of members that are connected by a connecting bolt P and is temporarily fixed to the connecting bolt (see FIG. 4). Furthermore, the spacer of the present invention is disposed between a substantially rectangular cylindrical frame 11 that supports the solar cell module 10 and the main member 21 of the array mount 20 (see FIG. 7).

本発明スペーサーの構成は、当接基盤１、突出板２、挿通孔３、係止突起４からなる（図１参照）。当接基盤１は、一方の部材に当接する部材で、該当接基盤１の盤面中央部から突出して他方の部材に当接する突出板２を形成している（図２参照）。図示例では、当接基盤１と突出板２とを金属板のプレス加工等で一体成形し、断面略円弧形状を成す突出板２を設けているが、当接基盤１と突出板２とを別体に形成することも可能である。また、突出板２の板厚は、連結ボルトＰのネジ山Ｐ１に係止する程度の厚みで形成することで、連結ボルトＰのネジ山Ｐ１に係止可能になる。   The configuration of the spacer of the present invention comprises a contact base 1, a protruding plate 2, an insertion hole 3, and a locking projection 4 (see FIG. 1). The contact base 1 is a member that contacts one member, and forms a protruding plate 2 that protrudes from the center of the board surface of the corresponding contact base 1 and contacts the other member (see FIG. 2). In the illustrated example, the contact base 1 and the projecting plate 2 are integrally formed by pressing a metal plate or the like, and the projecting plate 2 having a substantially arc-shaped cross section is provided. It is also possible to form it separately. Further, the projecting plate 2 can be locked to the thread P1 of the connecting bolt P by forming the protruding plate 2 with a thickness that can be locked to the thread P1 of the connecting bolt P.

該突出板２の板面中央に連結ボルトＰを挿通する挿通孔３が開穿され、該挿通孔３の一側縁部から突設されて挿通孔３の上下いずれか一方に向いて傾斜する係止突起４を形成している（図２参照）。図示例では、係止突起４の先端４Ａを平面略Ｖ字形状に形成することで、連結ボルトＰが該挿通孔３に対して略直交するときに該先端４Ａが連結ボルトＰの側面二箇所を支持するように設けている（図３参照）。   An insertion hole 3 through which the connecting bolt P is inserted is opened in the center of the plate surface of the protruding plate 2, and protrudes from one side edge portion of the insertion hole 3 so as to incline toward the upper or lower side of the insertion hole 3. A locking projection 4 is formed (see FIG. 2). In the illustrated example, the tip 4A of the locking protrusion 4 is formed in a substantially V-shaped plane so that when the connecting bolt P is substantially orthogonal to the insertion hole 3, the tip 4A is located on two side surfaces of the connecting bolt P. (See FIG. 3).

図１乃至図４に示す係止突起４は、挿通孔３から下方、すなわち当接基盤１方向に傾斜している（図２参照）。連結ボルトＰが、この係止突起４の傾斜面に接するとき、すなわち係止突起４の傾斜に沿ったときに本発明スペーサーが移動可能になるものである（図４（イ）参照）。更に、挿通孔３内の連結ボルトＰが該挿通孔３に対して略直交する状態のときに挿通孔３の内側縁部が連結ボルトＰのネジ山Ｐ１に係止すると共に、係止突起４の先端４Ａが連結ボルトＰの側面を支持してスペーサーがネジ山Ｐ１に沿って回転するように設けている（図４（ロ）参照）。図示例では、連結ボルトＰを挿入している部材（フレーム１１）にスペーサーを押圧することで、連結ボルトＰを安定させている。そして、連結ボルトＰの下端部に連結する他の部材（主材２１）を連結し、ナットＱにて固定する（図４（ハ）参照）。   The locking projections 4 shown in FIGS. 1 to 4 are inclined downward from the insertion hole 3, that is, toward the contact base 1 (see FIG. 2). The spacer of the present invention can be moved when the connecting bolt P is in contact with the inclined surface of the locking projection 4, that is, along the inclination of the locking projection 4 (see FIG. 4 (a)). Further, when the connecting bolt P in the insertion hole 3 is substantially orthogonal to the insertion hole 3, the inner edge of the insertion hole 3 is locked to the thread P1 of the connecting bolt P, and the locking projection 4 4A supports the side surface of the connecting bolt P, and the spacer is provided to rotate along the thread P1 (see FIG. 4B). In the illustrated example, the connecting bolt P is stabilized by pressing a spacer against the member (frame 11) in which the connecting bolt P is inserted. And the other member (main material 21) connected with the lower end part of the connection bolt P is connected, and it fixes with the nut Q (refer FIG. 4 (C)).

一方、図５（イ）乃至（ハ）に示す係止突起４は、本発明スペーサーの他の実施例を示している。すなわち、同図（イ）は、係止突起４を上方に向けたもので、同図（ロ）は、係止突起４の他に補助係止突起５を形成したもの、同図（ハ）は、傾斜した係止突起４の先端４Ａを更に折り返して連結ボルトＰのネジ山Ｐ１に係止せしめるものである。   On the other hand, the locking projections 4 shown in FIGS. 5A to 5C show another embodiment of the spacer of the present invention. That is, FIG. 4A shows the locking projection 4 facing upward, and FIG. 2B shows the auxiliary projection 5 formed in addition to the locking projection 4, FIG. Is for further folding back the tip 4A of the inclined locking projection 4 and locking it to the thread P1 of the connecting bolt P.

このとき、図５（ロ）は、挿通孔３の一側縁部から挿通孔３の上下いずれか一方に向いて傾斜する係止突起４と、挿通孔３の他側縁部から突設されて該係止突起４の上下反対方向に傾斜する補助係止突起５とを形成している。図示例では、傾斜が上向きのものを係止突起４とし、下向きのものを補助係止突起５としているが、いずれを係止突起４としてもよい。この場合、挿通孔３内の連結ボルトＰが係止突起４と補助係止突起５との傾斜に沿ったときにスペーサーが移動する。そして、挿通孔３内の連結ボルトＰが該挿通孔３に対して直交するときに係止突起４と補助係止突起５との先端４Ａ、５Ａが連結ボルトＰ側面のネジ山Ｐ１に係止するものである。   At this time, FIG. 5B is projected from the one side edge of the insertion hole 3 toward the upper or lower side of the insertion hole 3 and the other side edge of the insertion hole 3. Thus, an auxiliary locking projection 5 that is inclined in the opposite direction to the vertical direction of the locking projection 4 is formed. In the illustrated example, the upwardly inclined slope is the locking projection 4 and the downward slope is the auxiliary locking projection 5, but any of them may be the locking projection 4. In this case, the spacer moves when the connecting bolt P in the insertion hole 3 follows the inclination of the locking protrusion 4 and the auxiliary locking protrusion 5. When the connection bolt P in the insertion hole 3 is orthogonal to the insertion hole 3, the tips 4A and 5A of the locking projection 4 and the auxiliary locking projection 5 are locked to the thread P1 on the side surface of the connection bolt P. To do.

突出板２の挿通孔３は、前述のごとく、挿通孔３に対して連結ボルトＰが斜めのときにスペーサーがスライド移動し、連結ボルトＰが略直交するときにネジ山Ｐ１に係止するように形成している（図４（イ）、（ロ）参照）。図示例では、係止突起４に相対する挿通孔３の内側縁部を平面略Ｖ字形状に形成することで、連結ボルトＰが略直交するときに該内側縁部が連結ボルトＰのネジ山Ｐ１二箇所に係止するように設けている（図３参照）。また、このような挿通孔３によると、本発明スペーサーを係止突起４に沿って傾けたときに挿通孔３がネジ山Ｐ１に係合し難くなり、スライド移動がスムーズになる利点もある。   As described above, the insertion hole 3 of the protruding plate 2 is configured such that the spacer slides when the connection bolt P is oblique with respect to the insertion hole 3 and is locked to the thread P1 when the connection bolt P is substantially orthogonal. (See FIGS. 4A and 4B). In the illustrated example, the inner edge of the insertion hole 3 facing the locking projection 4 is formed in a substantially V-shaped plane so that when the connecting bolt P is substantially orthogonal, the inner edge is a thread of the connecting bolt P. P1 is provided so as to be locked at two places (see FIG. 3). Moreover, according to such an insertion hole 3, when the spacer of the present invention is tilted along the locking projection 4, the insertion hole 3 becomes difficult to engage with the thread P1, and there is an advantage that the sliding movement is smooth.

本発明スペーサーの使用例を図７に示している。すなわち、連結ボルトＰで連結される一対の部材は、一方が太陽電池モジュール１０のフレーム１１であり、他方がアレイ用架台２０の主材２１である。フレーム１１は角筒状を成し、下面に水抜き孔１２が開穿されている。そして、これらフレーム１１と主材２１とを連結する際に、水抜き孔１２を塞がないようにするため、本発明スペーサーを使用する。この場合、フレーム１１に予め挿通した連結ボルトＰのネジ山Ｐ１にスペーサーをスライド装着するものである。   An example of use of the spacer of the present invention is shown in FIG. That is, one of the pair of members connected by the connection bolt P is the frame 11 of the solar cell module 10, and the other is the main material 21 of the array mount 20. The frame 11 has a rectangular tube shape, and a drain hole 12 is opened on the lower surface. And when connecting these flame | frame 11 and the main material 21, in order not to block the drain hole 12, the spacer of the present invention is used. In this case, a spacer is slid onto the thread P1 of the connecting bolt P that has been inserted through the frame 11 in advance.

この使用例によると、両手で太陽電池モジュール１０の位置を調整することが可能になる。すなわち、フレーム１１のボルト挿通孔に予め連結ボルトＰを挿通しておき、フレーム１１下面の連結ボルトＰに本発明スペーサーをスライド装着し（図４（イ）参照）、更にスペーサーを回転させてフレーム１１に固定する（図４（ロ）参照）。この状態にすると、連結ボルトＰの下端部を目印にして主材２１のボルト挿通孔に探す作業が容易になる。しかも、主材２１のボルト挿通孔が主材２１に沿って傾斜していても、連結ボルトＰがフレーム１１に固定されているので、連結ボルトＰを主材２１のボルト挿通孔に挿入する作業も容易に行える（図４（ハ）参照）。   According to this use example, the position of the solar cell module 10 can be adjusted with both hands. That is, the connecting bolt P is inserted through the bolt insertion hole of the frame 11 in advance, the spacer of the present invention is slid onto the connecting bolt P on the lower surface of the frame 11 (see FIG. 4A), and the spacer is further rotated to rotate the frame. 11 (see FIG. 4B). In this state, it is easy to search for the bolt insertion hole of the main material 21 with the lower end portion of the connecting bolt P as a mark. Moreover, even if the bolt insertion hole of the main material 21 is inclined along the main material 21, the connection bolt P is fixed to the frame 11, so that the connection bolt P is inserted into the bolt insertion hole of the main material 21. Can also be easily performed (see FIG. 4C).

尚、本発明は、図示例に限定されるものではなく、当接基盤１や突出板２、あるいは挿通孔３や係止突起４の形状や構造の変更、若しくは材質の変更などは、本発明の要旨を変更しない範囲において自由に変更できるものである。   In addition, this invention is not limited to the example of illustration, The change of the shape or structure of the contact | abutting base | substrate 1, the protrusion board 2, or the insertion hole 3, the latching protrusion 4, or a material is the present invention. As long as the gist of the invention is not changed, it can be freely changed.
