実施の形態１．
図１は、この発明の太陽電池モジュール架台の実施の形態１の斜視図である。図２は、図１のＡ面の断面図である。図３は、レール部材の斜視図である。本実施の形態の架台５０は、太陽電池モジュールの縁部に係合する係合部材２０と、係合部材２０を貫通するタッピングネジ（ネジ）３０と、タッピングネジ３０が長手方向任意の位置で締結する長尺のレール部材１０とから構成されている。 Embodiment 1 FIG.
FIG. 1 is a perspective view of Embodiment 1 of the solar cell module mount of the present invention. 2 is a cross-sectional view of the A surface of FIG. FIG. 3 is a perspective view of the rail member. The gantry 50 of the present embodiment includes an engaging member 20 that engages with an edge of the solar cell module, a tapping screw (screw) 30 that penetrates the engaging member 20, and the tapping screw 30 at an arbitrary position in the longitudinal direction. It is comprised from the elongate rail member 10 to fasten.

レール部材１０は、アルミニウム系合金の押出し加工にて作製され、細長直線状を成し全長にわたり断面コ字状に形成された本体１１と、本体１１のコ字状開口部の反対側に形成されたフランジ部１２とからなる。レール部材１０は、屋根などの設置面に固定される際、本体１１のコ字状開口部を上方に向けて固定される。フランジ部１２は、設置面に固定される際、設置面に沿って広がる方向に延び、安定して固定されるよう裏面に大面積の固定面を形成している。つまり、レール部材１０においては、設置場所に向けられる固定面に対して反対側に開口を向けて断面コ字状のコ字状溝が長手方向に延びて形成されている。   The rail member 10 is formed by extrusion processing of an aluminum-based alloy, and is formed on the opposite side of the main body 11 formed in an elongated linear shape and having a U-shaped cross section over the entire length, and the U-shaped opening of the main body 11. And a flange portion 12. When the rail member 10 is fixed to an installation surface such as a roof, the U-shaped opening of the main body 11 is fixed upward. When the flange portion 12 is fixed to the installation surface, the flange portion 12 extends in a direction extending along the installation surface and forms a fixed surface having a large area on the back surface so as to be stably fixed. That is, in the rail member 10, a U-shaped groove having a U-shaped cross section is formed extending in the longitudinal direction with the opening facing the opposite side to the fixed surface directed to the installation location.

タッピングネジ３０は、ステンレスを初めとする鋼系材料にて作製され、例えば下穴が形成された締結箇所にねじ込まれる際、自らタップ加工（ネジ切り）しながらねじ込まれるネジである。   The tapping screw 30 is made of a steel-based material such as stainless steel, and is screwed while being tapped (threaded) by itself when screwed into a fastening portion where a pilot hole is formed, for example.

レール部材１０の本体１１のコ字状開口部の対向する２つの内面１１ａ，１１ａは、タッピングネジ３０がねじ込まれる際、タッピングネジ３０が雌ねじ部を形成しながら螺合するのに適度な溝幅となっている。そして、さらに２つの内面１１ａ，１１ａの開口部よりには、タッピングネジ３０が雌ねじ部を形成しやすいように、タッピングネジ３０のネジ山と同じピッチの断面三角形の係合可能なネジ係合溝１１ｂ，１１ｂが全長にわたり形刻されている。   The two inner surfaces 11a, 11a opposite to each other of the U-shaped opening of the main body 11 of the rail member 10 have an appropriate groove width so that when the tapping screw 30 is screwed, the tapping screw 30 is screwed together while forming the female screw portion. It has become. Further, an engaging screw engaging groove having a triangular cross-section having the same pitch as the thread of the tapping screw 30 so that the tapping screw 30 can easily form a female screw portion from the openings of the two inner surfaces 11a, 11a. 11b and 11b are engraved over the entire length.

図３に良く示されるように、２つの内面１１ａ，１１ａのネジ係合溝１１ｂ，１１ｂの深さ方向中間部に、タッピングネジ３０がねじ込まれる際、これを突き破る薄肉部１１ｃがネジ係合溝１１ｂ，１１ｂ間を塞ぐように架け渡されて形成されている。そして、タッピングネジ３０がねじ込まれる際、薄肉部１１ｃを突き破ることで、タッピングネジ３０は、レール部材１０の長手方向の移動を完全に規制される。この薄肉部１１ｃの厚さは、タッピングネジ３０のネジ部径の４分の１程度が、作業性の観点から望ましい。また、この薄肉部１１ｃの上部表面には凹凸が作製されている。その結果、タッピングを容易とし、作業性・締結状態の安定性を向上させている。   As shown well in FIG. 3, when the tapping screw 30 is screwed into the intermediate portion in the depth direction of the screw engaging grooves 11b, 11b of the two inner surfaces 11a, 11a, the thin-walled portion 11c that breaks through this is the screw engaging groove. 11b is formed so as to bridge between 11b. When the tapping screw 30 is screwed, the tapping screw 30 is completely restricted from moving in the longitudinal direction of the rail member 10 by breaking through the thin portion 11c. The thickness of the thin portion 11c is preferably about one quarter of the screw portion diameter of the tapping screw 30 from the viewpoint of workability. In addition, irregularities are formed on the upper surface of the thin portion 11c. As a result, tapping is facilitated, and workability and stability of the fastening state are improved.

このような構成の太陽電池モジュール架台５０は、まず、レール部材１０のフランジ部１２に開口する貫通穴１２ａに挿入された図示しない木ネジなどにより、例えば屋根の垂木にネジ止めされることにより、レール部材１０を屋根の設置面に固定され、次いで、係合部材２０とレール部材１０との間に太陽電池モジュール８０の縁部を挟み込み、係合部材２０を貫通するタッピングネジ３０をレール部材１０にねじ込んで締結することにより、太陽電池モジュール８０を屋根に設置する。   The solar cell module mount 50 having such a configuration is first screwed to a rafter of a roof, for example, with a wood screw (not shown) inserted into a through hole 12a opened in the flange portion 12 of the rail member 10, The rail member 10 is fixed to the installation surface of the roof, and then the edge of the solar cell module 80 is sandwiched between the engaging member 20 and the rail member 10, and the tapping screw 30 penetrating the engaging member 20 is inserted into the rail member 10. The solar cell module 80 is installed on the roof by screwing in and fastening.

図４は、架台５０にて太陽電池モジュールを固定した具体的な様子を示す斜視図である。太陽電池モジュール８０は、図示しない複数の太陽電池セルを併設して樹脂封止して成る平板状の太陽電池パネル８１と、太陽電池パネル８１の外縁部を全周にわたって囲む枠部材８２とから構成されている。枠部材８２は、断面コの字形を成し太陽電池パネル８１の外縁部を全周にわたって挟み込む縁保持部８２ａと、この縁保持部８２ａの背面から太陽電池パネル８１の裏面側に延びる板状部８２ｂと、この板状部８２ｂの下端からパネル内方に延びて形成された内フランジ部８２ｃと、板状部８２ｂの下端からパネル外方に延びて形成された外フランジ部８２ｄとから構成されている。係合部材２０の一端が外フランジ部８２ｄの上面に当接している状態で、タッピングネジ３０をレール部材１０にねじ込み、係合部材２０下面とレール部材１０の上面とで外フランジ部８２ｄを挟み込むようにして、太陽電池モジュール８０をレール部材１０に固定する。   FIG. 4 is a perspective view showing a specific state in which the solar cell module is fixed by the gantry 50. The solar cell module 80 includes a flat solar cell panel 81 formed by resin-sealing a plurality of solar cells not shown, and a frame member 82 that surrounds the outer edge of the solar cell panel 81 over the entire circumference. Has been. The frame member 82 has a U-shaped cross section, and an edge holding portion 82a that sandwiches the outer edge portion of the solar cell panel 81 over the entire circumference, and a plate-like portion that extends from the back surface of the edge holding portion 82a to the back surface side of the solar cell panel 81. 82b, an inner flange portion 82c formed to extend inward from the lower end of the plate-like portion 82b, and an outer flange portion 82d formed to extend outward from the lower end of the plate-like portion 82b. ing. The tapping screw 30 is screwed into the rail member 10 while one end of the engaging member 20 is in contact with the upper surface of the outer flange portion 82d, and the outer flange portion 82d is sandwiched between the lower surface of the engaging member 20 and the upper surface of the rail member 10. In this way, the solar cell module 80 is fixed to the rail member 10.

図５及び図６は、レール部材１０の他の使い方示すものであり、図５は、係合部材２０を用いずに、枠部材８２の内フランジ部８２ｃを貫通するタッピングネジ３０をレール部材１０上に直接締結する様子を示す斜視図であり、図６は、レール部材１０Ａ上に直交するように他のレール部材１０Ｂを重ねて使用する様子を示す斜視図である。図５の使い方においては、部品点数を削減することができる。また、図６の使い方においては、太陽電池モジュールの主面に対して、縦横方向に位置調整することができる。このように架台５０は、図４に示すような基本的な使い方のみならず、いろいろな使い方をされてよい。   5 and 6 show other uses of the rail member 10, and FIG. 5 shows that the tapping screw 30 penetrating the inner flange portion 82c of the frame member 82 is used for the rail member 10 without using the engaging member 20. FIG. It is a perspective view which shows a mode that it fastens directly on, FIG. 6 is a perspective view which shows a mode that other rail member 10B is piled up and used so that it may orthogonally cross on rail member 10A. In the usage of FIG. 5, the number of parts can be reduced. Moreover, in the usage of FIG. 6, the position can be adjusted in the vertical and horizontal directions with respect to the main surface of the solar cell module. As described above, the gantry 50 may be used in various ways in addition to the basic usage shown in FIG.

本実施の形態においては、上記のような構成を採用することで、コ字状溝に沿った任意の場所にネジ締結をすることが可能となるため、太陽電池モジュールを最適に配置するための位置調整において、溝に沿った方向に位置を決定後、下穴加工やスライド金具の設置などの二次的な作業を省略することができ、作業性を向上することが出来る。また、スライド金具を用いた方式と比較すると、スライド金具をなくすことが出来るため、架台全体としてのコストも低減できる。   In the present embodiment, by adopting the configuration as described above, it is possible to fasten the screw at an arbitrary location along the U-shaped groove, so that the solar cell module is optimally arranged. In the position adjustment, after determining the position in the direction along the groove, secondary work such as drilling of a pilot hole or installation of a slide fitting can be omitted, and workability can be improved. Moreover, compared with the system using a slide metal fitting, since the slide metal fitting can be eliminated, the cost of the entire gantry can be reduced.

なお、本実施の形態においては、上記のように、レール部材１０は、アルミニウム系合金の押出し加工にて作製されている。アルミニウム系合金の押出し加工は、軸方向に同一の断面形状であれば比較的安価に様々な断面形状を直接作製できるため、追加工無しでネジ係合溝１１ｂ，１１ｂを容易に作製することができる。また、アルミニウム系合金は、繊維強化樹脂などの非金属材料と比較すると、耐環境性、強度に優れており、屋外にて１０年以上の長期にわたって使用される太陽電池モジュール架台に適している。レール部材１０をアルミニウム系合金で作製した場合、タッピングネジ３０はステンレスを初めとする鋼系材料を用いればよい。その場合、タッピングネジ３０には、アルミニウムとの電位差による腐食を避けるため、腐食防止コーティングを行うのが望ましい。   In the present embodiment, as described above, the rail member 10 is manufactured by extrusion of an aluminum alloy. Since the extrusion process of the aluminum-based alloy can directly produce various cross-sectional shapes relatively inexpensively as long as they have the same cross-sectional shape in the axial direction, the screw engagement grooves 11b and 11b can be easily produced without additional processing. it can. In addition, aluminum alloys are superior in environmental resistance and strength compared to non-metallic materials such as fiber reinforced resins, and are suitable for solar cell module mounts used outdoors for a long period of 10 years or more. When the rail member 10 is made of an aluminum alloy, the tapping screw 30 may be made of a steel material such as stainless steel. In that case, the tapping screw 30 is preferably subjected to a corrosion prevention coating in order to avoid corrosion due to a potential difference with aluminum.

なお、本実施の形態のレール部材１０においては、タッピングネジ３０の長手方向の移動を完全に抑制するために、薄肉部１１ｃが設けられているが、薄肉部１１ｃが無くてもタッピングネジ３０の移動を防止でき良好に締結できる場合には薄肉部１１ｃは省略されてもよい。   In addition, in the rail member 10 of this Embodiment, in order to suppress the movement of the tapping screw 30 in the longitudinal direction completely, the thin portion 11c is provided, but even if there is no thin portion 11c, the tapping screw 30 The thin-walled portion 11c may be omitted when the movement can be prevented and the fastening can be performed satisfactorily.

また、本実施の形態のレール部材１０には、タッピングネジ３０が雌ねじ部を形成しやすいように２つの内面１１ａ，１１ａの開口部よりにネジ係合溝１１ｂ，１１ｂが全長にわたり形刻されている。そのため、タッピングネジ３０の締結時にねじ山形成が容易となり、ネジ締結時の作業性・締結状態の安定性が向上される。しかしながら、材料などの選択により、タッピングネジ３０が締結するのにネジ係合溝１１ｂ，１１ｂがなくても十分に雌ねじ部を形成できるのであれば、ネジ係合溝１１ｂ，１１ｂは必ずしも必要とするものではない。逆に全く雌ねじ部を形成できないものであっても、ネジ係合溝１１ｂ，１１ｂをネジ係合可能な完全な形に成形しておけばタッピングネジ３０に限らず、一般的なネジであっても締結することができる。   Further, in the rail member 10 of the present embodiment, screw engagement grooves 11b and 11b are engraved over the entire length from the openings of the two inner surfaces 11a and 11a so that the tapping screw 30 can easily form the female screw portion. Yes. Therefore, the thread formation is facilitated when the tapping screw 30 is fastened, and the workability and the stability of the fastened state when the screw is fastened are improved. However, the screw engagement grooves 11b and 11b are necessarily required if the internal thread portion can be sufficiently formed without the screw engagement grooves 11b and 11b to fasten the tapping screw 30 by selecting the material. It is not a thing. On the contrary, even if the female thread portion cannot be formed at all, if the screw engagement grooves 11b and 11b are formed into a complete shape that can be screw-engaged, not only the tapping screw 30 but also a general screw. Can also be concluded.

FIG. 7 is a perspective view of Embodiment 2 of the solar cell module mount of the present invention. 8 is a cross-sectional view of the B surface of FIG. In the gantry 55 of the present embodiment, the engaging member 25 has a U-shaped cross section that covers the main body 11 of the rail member 10, and has two inner surfaces 25 a and 25 a that are in contact with the two outer surfaces of the main body 11. have. In addition, an uneven slip stopper 25b is formed at the tip of the opening of the U-shaped wall surface in contact with the flange portion 12 of the rail member 10 to restrict movement in the longitudinal direction.

このように本実施の形態においては、タッピングネジ３０によって固定される係合部材２５が、レール部材１０のコ字状溝の溝状のタッピングネジ３０の締結位置の外側を覆うようにはめ込まれている。この結果、係合部材２５の剛性により、コ字状溝の雌ねじ部形成位置がタッピングネジ３０の径方向に拡大するのが防がれ、締結強度を向上させることができる。   Thus, in the present embodiment, the engaging member 25 fixed by the tapping screw 30 is fitted so as to cover the outside of the fastening position of the groove-shaped tapping screw 30 of the U-shaped groove of the rail member 10. Yes. As a result, the rigidity of the engagement member 25 prevents the female thread portion forming position of the U-shaped groove from expanding in the radial direction of the tapping screw 30, and the fastening strength can be improved.

このような構造をとることで、ネジ締結に失敗したり、太陽電池モジュールを複数回取り付け直したりすることがありコ字状溝の雌ねじ部がつぶれてしまったとしても、この雌ねじ部を修復することなく、軸方向に同一の位置に図示しない係合部材を締結することが可能となる。 Embodiment 3 FIG.
FIG. 9: is a perspective view of the rail member which shows Embodiment 3 of the solar cell module mount of this invention. In the mount of the solar cell module of the present embodiment, the U-shaped grooves formed by the two screw engaging grooves 11b facing each other are formed in parallel in the rail member 15.
By adopting such a structure, even if screw fastening fails or the solar cell module may be reattached multiple times, even if the female screw part of the U-shaped groove is crushed, this female screw part is repaired Without this, it becomes possible to fasten the engaging member (not shown) at the same position in the axial direction.

なお、本実施の形態のようにレール部材に複数のコ字状溝が無い場合において、同一の場所にてネジ止めをする場合には、インサートなどのネジ山形成工具を用いてネジ山を修復作業する必要がある。   In addition, when there are no plurality of U-shaped grooves in the rail member as in this embodiment, when screwing in the same place, the thread is repaired using a thread forming tool such as an insert. I need to work.

実施の形態４．
図１０は、この発明の太陽電池モジュール架台の実施の形態４の斜視図である。本実施の形態の太陽電池モジュール架台６０においては、タッピングネジ３０のネジ係合部にゆるみ防止の硬化充填材４１が充填されている。これにより、タッピングネジ３０のゆるみが防止されるとともに長手方向の移動がさらに規制される。また、雨水等の浸入が防止され係合部材２０やタッピングネジ３０の腐食が低減する。 Embodiment 4 FIG.
