Abstract

<P>PROBLEM TO BE SOLVED: To provide a base for installation of a structure, which firmly supports even a large number of solar cell modules, and which facilitates the construction work thereof by using fewer components. <P>SOLUTION: A left side end of each side plate 15a of a first crosspiece member 151 is sandwiched by being inserted into the inside of the one-side end of each side plate 15a of a second crosspiece member 152. The side plates 15a spread on the sides of hat-shaped cross-section openings of crosspieces 15 (the crosspiece members 151 and 152), respectively. Thus, when the one-side end of each side plate 15a of a second crosspiece member 152 has only to cover the left side end of each first side plate 15a of the first crosspiece member 151, the left side end of each first side plate 15a is sandwiched by being inserted into the inside of the one-side end of each second side plate 15a. In this state, each side plate 15a of the second crosspiece member 152 is connected to each side plate 15a of the first crosspiece member 151. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

本発明は、太陽電池モジュール等の構造物を設置するための構造物用設置架台、その施工方法、及び太陽電池システムに関する。   The present invention relates to a structure installation stand for installing a structure such as a solar cell module, a construction method thereof, and a solar cell system.

この種の架台は、構造物の荷重を単に支持するというだけではなく、構造物に受けた風圧等にも耐えねばならないため、高い強度を要求される。特に、太陽電池モジュールを支持する場合は、太陽電池モジュールが平板状であって傾斜して配置されることから、太陽電池モジュールに大きな風圧がかかり易く、架台の強度に十分な注意が払われている。   This kind of gantry is required not only to support the load of the structure but also to withstand the wind pressure received on the structure, and therefore requires high strength. In particular, when the solar cell module is supported, the solar cell module is flat and inclined, so that a large wind pressure is easily applied to the solar cell module, and sufficient attention is paid to the strength of the gantry. Yes.

例えば、特許文献1では、複数の筒状体を組み合わせた支持レールを固定し、この支持レールにより太陽電池モジュールの端部を支持している。筒状体そのものの断面係数が大きいため、複数の筒状体の組み合わせにより支持レールの強度が高くなる。   For example, in patent document 1, the support rail which combined the some cylindrical body is fixed, and the edge part of the solar cell module is supported by this support rail. Since the cylindrical body itself has a large section modulus, the strength of the support rail is increased by combining a plurality of cylindrical bodies.

また、特許文献2では、ハット型の断面形状を有する複数のフレームを並設し、これらのフレーム上に太陽電池モジュールを固定支持している。このハット型のフレームの断面係数も大きく、フレーム強度も高い。   In Patent Document 2, a plurality of frames having a hat-shaped cross-sectional shape are juxtaposed, and a solar cell module is fixedly supported on these frames. The hat-shaped frame has a large section modulus and high frame strength.

ここで、特許文献1及び2では、住宅等への太陽電池モジュールの設置が前提となっているので、太陽電池モジュールの設置面積が限られ、支持レールやフレームは、長くても数m程度であると考えられる。   Here, in patent documents 1 and 2, since the installation of the solar cell module in a house or the like is a premise, the installation area of the solar cell module is limited, and the support rail and the frame are about several meters at the longest. It is believed that there is.

しかしながら、大規模な発電所等においては、多数の太陽電池モジュールを並べて設置することから、特許文献1の支持レールや特許文献2のフレームを適用するならば、これらを延長する必要がある。   However, since a large number of solar cell modules are installed side by side in a large-scale power plant or the like, if the support rails of Patent Document 1 and the frame of Patent Document 2 are applied, these need to be extended.

特許文献1では、2本の支持レールの一方の端部に筒状部を設けると共に他方の端部に棒状部を設け、これらの端部の筒状部と棒状部を相互に嵌合させて、2本の支持レールを接続し、これにより支持レールの延長を可能にしている。ところが、これらの筒状部や棒状部を設けると、支持レールの形状が複雑化したり、部品点数が増大する。また、2本の支持レールの筒状部と棒状部を嵌合させるには、これらの支持レールを直線状に支持する必要があり、その作業が容易ではない。このため、このような支持レールを大規模な発電所等に適用したならば、コストが非常に高くなり、施工作業が困難になる。   In Patent Document 1, a cylindrical portion is provided at one end portion of two support rails, and a rod-like portion is provided at the other end portion, and the cylindrical portion and the rod-like portion of these end portions are fitted to each other. Two support rails are connected, which makes it possible to extend the support rails. However, when these cylindrical portions and rod-shaped portions are provided, the shape of the support rail becomes complicated and the number of parts increases. Moreover, in order to fit the cylindrical part and bar-shaped part of two support rails, it is necessary to support these support rails linearly, and the operation | work is not easy. For this reason, if such a support rail is applied to a large-scale power plant or the like, the cost becomes very high and the construction work becomes difficult.

また、特許文献2では、フレームの延長についての記載がなく、大規模な発電所等へのフレームの適用が考えられていない。   Moreover, in patent document 2, there is no description about the extension of a flame | frame, and application of the flame | frame to a large-scale power plant etc. is not considered.

そこで、本発明は、上記従来の問題点に鑑みてなされたものであり、多数の太陽電池モジュールであっても、これらの太陽電池モジュールを強固に支持することができ、部品点数が少なく、その施工作業が容易な構造物設置用架台、構造物設置用架台の施工方法、及び太陽電池システムを提供することを目的とする。   Therefore, the present invention has been made in view of the above-mentioned conventional problems, and even with a large number of solar cell modules, these solar cell modules can be firmly supported, and the number of components is small. It is an object of the present invention to provide a structure installation stand, a structure installation method, and a solar cell system that are easy to perform.

A plurality of arms each projecting, a plurality of vertical beams spanned and fixed to the other end of each base beam and the upper end of each arm, and arranged to be orthogonal to each vertical beam, A plurality of horizontal bars arranged in parallel on the vertical bars and arranged with the structures mounted thereon, the horizontal bars having a main plate and a pair of side plates extending in the same direction; A plurality of crosspieces each having a shape in which the sides of the side plate extending in the direction are connected by the main plate are connected, and at least one main plate end or a part of the side plate end of each of the connected crosspieces is cut. Each side plate end portion of each crosspiece member is outside the other side plate end portion. Or in a state superposed on the inner side, the side plates end of the each side plate end of the one and the other is connected.

また、前記各ベース桟、前記各アーム、及び前記各縦桟は、前記桟部材と同一断面を含む部材からなる。   Each base beam, each arm, and each vertical beam are formed of members having the same cross section as the beam member.

更に、前記各横桟、前記各ベース桟、前記各アーム、及び前記各縦桟の桟部材は、相互に対向する一対の側板、該各側板を連結する主板、及び前記各側板の縁で折り曲げられたそれぞれの鍔からなるハット型断面を有する。   Furthermore, the crosspieces of the horizontal crosspieces, the base crosspieces, the arms, and the vertical crosspieces are bent at a pair of side plates facing each other, a main plate connecting the side plates, and edges of the side plates. Each having a hat-shaped cross section.

また、前記各横桟、前記各ベース桟、前記各アーム、及び前記各縦桟の桟部材は、ロールフォーミング加工により形成されている。   In addition, the cross members of the horizontal bars, the base bars, the arms, and the vertical bars are formed by roll forming.

次に、本発明の施工方法は、上記本発明の構造物設置用架台の施工方法であって、前記各桟部材の一方の各側板端部を前記他方の各側板端部の内側又は外側に重ねた後、前記一方の各側板端部と前記他方の各側板端部を接続している。   Next, the construction method of the present invention is the construction method of the structure installation stand of the present invention, wherein one side plate end of each crosspiece member is placed inside or outside the other side plate end. After overlapping, the one side plate end and the other side plate end are connected.

また、本発明の太陽電池システムは、上記本発明の構造物設置用架台を備え、この構造物設置用架台の横桟上に構造物としての太陽電池モジュールを搭載している。   Moreover, the solar cell system of the present invention includes the above-described structure installation stand of the present invention, and a solar cell module as a structure is mounted on a horizontal rail of the structure installation stand.

本発明の構造物設置用架台では、桟は、同一方向に延びる主板及び一対の側板を有し、該一対の側板の前記方向に延びる各辺が前記主板により連結された形状の桟部材を複数接続したものである。このような桟部材は、コの字型もしくはコの字型に近い断面形状となり、その断面係数が大きく、桟部材の強度が高くなる。このため、複数の桟部材を接続した桟の強度も高くなる。   In the structure installation stand of the present invention, the crosspiece has a main plate and a pair of side plates extending in the same direction, and a plurality of crosspiece members each having a shape in which the sides extending in the direction of the pair of side plates are connected by the main plate. Connected. Such a cross member has a U-shape or a cross-sectional shape close to a U-shape, has a large section coefficient, and increases the strength of the cross member. For this reason, the intensity | strength of the cross | link which connected the some crosspiece member also becomes high.

また、接続された各桟部材の少なくとも一方の主板端部もしくは側板端部の一部が切られた形状とされている。これにより、各桟部材の一方の各側板端部を他方の各側板端部の外側または内側に重ねることが容易になる。そして、この状態で各桟部材端部を接続しているので、各桟部材の接続箇所では、両側の側板が2重構造となり、その強度が向上する。しかも、桟を延長するべく、桟部材の本数を増やしても、各桟部材の一方の各側板端部を他方の各側板端部の外側又は内側に重ねて接続するという工程を繰り返すだけであるから、施工作業が容易である。   Further, at least one main plate end portion or side plate end portion of each connected crosspiece member has a cut shape. Thereby, it becomes easy to overlap each one side plate edge part of each crosspiece member on the outer side or inner side of the other side plate edge part. And since each crosspiece member edge part is connected in this state, the side plate of both sides becomes a double structure in the connection location of each crosspiece member, and the intensity | strength improves. Moreover, even if the number of crosspiece members is increased in order to extend the crosspieces, only the process of connecting one side plate end of each crosspiece member on the outside or inside of the other sideplate end is repeated. Therefore, construction work is easy.

例えば、接続された各桟部材の少なくとも一方の主板端部と各側板端部の一部を前記方向に沿って切除するか、もしくは主板端部と各側板端部間に前記方向に沿う切り込みを形成すればよい。   For example, at least one main plate end portion and each side plate end portion of each connected crosspiece member are cut along the direction, or a cut along the direction is made between the main plate end portion and each side plate end portion. What is necessary is just to form.

このような接続構造では、接続された各桟部材の主板の幅が同一であっても、各桟部材を連結することができる。   In such a connection structure, even if the width | variety of the main plate of each connected crosspiece member is the same, each crosspiece member can be connected.

また、接続された各桟部材端部の少なくとも一方の主板端部を切除した場合は、各桟部材端部の接続箇所で該各桟部材の主板が離間する。よって、各桟部材の主板が相互に干渉することはなく、各桟部材の端部の接続が容易になる。   Further, when at least one main plate end of each connected cross member end is cut off, the main plate of each cross member is separated at the connection portion of each cross member end. Therefore, the main plates of the crosspieces do not interfere with each other, and the end portions of the crosspieces can be easily connected.

更に、各桟部材の一方の各側板が他方の各側板の外側又は内側に重ねられるように、各側板が弾性変形する。すなわち、各側板の弾性変形により、各桟部材の一方の各側板を他方の各側板の外側又は内側に重ねることが可能になる。   Further, each side plate is elastically deformed such that one side plate of each crosspiece member is overlapped on the outside or inside of the other side plate. That is, by elastic deformation of each side plate, one side plate of each crosspiece member can be stacked on the outside or inside of the other side plate.

また、一方又は他方の各側板端部の内側にパイプを配置し、ボルトを一方の各側板端部の孔、他方の桟部材の各側板端部の孔、及びパイプに通して、ボルトの端部にナットをネジ込んで締め込むことにより各桟部材端部を接続している。この場合は、1本のボルト、1本のパイプ、及び1個のナットにより各桟部材端部を接続することができ、部品点数及び組立て工数の増大を抑えることができる。   Also, pipes are arranged inside one or other side plate end, and bolts are passed through holes in one side plate end, holes in each side plate end of the other crosspiece member, and pipes, and bolt ends. The end portions of the crosspiece members are connected by screwing nuts into the sections. In this case, each crosspiece member end can be connected by one bolt, one pipe, and one nut, and an increase in the number of parts and assembly man-hours can be suppressed.

あるいは、一方又は他方の各側板端部の内側に筒状雌ねじ部材を配置し、2本のボルトを一方の各側板端部の孔及び他方の各側板端部の孔を通じて筒状雌ねじ部材両端から該筒状雌ねじ部材内側の雌ネジにそれぞれねじ込んで締め込むことにより各桟部材端部を接続している。この場合は、2本のボルト、1本の筒状雌ねじ部材により各桟部材端部を接続することができ、部品点数及び組立て工数の増大を抑えることができる。   Alternatively, a cylindrical female screw member is arranged inside one or the other side plate end portion, and two bolts are inserted from both ends of the cylindrical female screw member through holes in one side plate end portion and holes in each other side plate end portion. The end portions of the crosspiece members are connected to each other by screwing the female screw inside the cylindrical female screw member. In this case, the end portions of the crosspiece members can be connected by two bolts and one cylindrical female screw member, and an increase in the number of parts and assembly man-hours can be suppressed.

また、桟部材の各側板の間隔が該桟部材の主板から離れるほど広くなるように主板に対する各側板の折り曲げ角度を設定している。つまり、桟部材の開口側が広くされている。この場合は、一方の桟部材の各側板を他方の桟部材の各側板に被せるだけで、一方の桟部材の各側板内側に他方の桟部材の各側板を容易に重ねることが可能になる。   Further, the bending angle of each side plate with respect to the main plate is set so that the interval between the side plates of the cross member becomes wider as the distance from the main plate of the cross member increases. That is, the opening side of the crosspiece member is widened. In this case, each side plate of the other cross member can be easily overlapped inside each side plate of the one cross member only by covering each side plate of the one cross member on each side plate of the other cross member.

更に、桟部材は、相互に対向する一対の側板、各側板の対向一辺を連結する主板、及び各側板の縁で折り曲げられたそれぞれの鍔からなるハット型断面を有する。このハット型断面の断面係数は、コの字型断面の断面係数よりも大きく、桟部材の強度がより高くなる。   Furthermore, the crosspiece member has a hat-shaped cross section that includes a pair of side plates facing each other, a main plate that connects opposite sides of each side plate, and each ridge bent at the edge of each side plate. The section modulus of the hat-shaped section is larger than the section coefficient of the U-shaped section, and the strength of the crosspiece member is further increased.

また、桟部材がロールフォーミング加工により形成されている。このロールフォーミング加工は、桟部材の大量生産に好適であり、桟部材のコストを低減することができる。   Moreover, the crosspiece member is formed by roll forming. This roll forming process is suitable for mass production of crosspieces, and can reduce the cost of the crosspieces.

更に、桟を構成するべく接続された複数の桟部材の接続箇所近傍を支持して、該桟を架設している。この接続箇所近傍を支持することにより該接続箇所を補強することができる。   Furthermore, the crosspieces are constructed so as to support the vicinity of connection points of a plurality of crosspiece members connected to form the crosspieces. By supporting the vicinity of this connection location, the connection location can be reinforced.

また、桟を3本並べて架設し、これらの桟間に各構造物を架け渡して搭載しており、並べられた各桟のうちの中央のものだけに補強部材を付設している。ここで、3本の桟間に各構造物を架け渡して搭載する場合は、中央の桟に大きな荷重がかかり、両側の桟に小さな荷重がかかる。そこで、両側の桟にかかる小さな荷重に合わせて、3本の桟の強度を設定して、各桟を共通化すれば、各桟の軽量化とコストの低減を果たすことができる。ただし、中央の桟の強度が不足するので、この中央の桟に補強部材を付設する。   In addition, three bars are installed side by side, and each structure is bridged and mounted between these bars, and a reinforcing member is attached only to the central one of the arranged bars. Here, when mounting each structure between the three crosses, a large load is applied to the central cross and a small load is applied to both crosses. Therefore, if the strength of the three bars is set according to the small load applied to the bars on both sides and the bars are made common, the weight of each bar can be reduced and the cost can be reduced. However, since the strength of the central beam is insufficient, a reinforcing member is attached to the central beam.

換言すれば、各桟のうちの中央のものだけに補強部材を付設するという構造により、両側の桟にかかる小さな荷重を基準にして、3本の桟の強度を設定し、各桟の軽量化とコストの低減を果たすことを可能にしている。   In other words, a structure in which a reinforcing member is attached only to the center of each of the bars, the strength of the three bars is set based on the small load applied to the bars on both sides, and the weight of each bar is reduced. And make it possible to reduce costs.

仮に、中央の桟にかかる大きな荷重に合わせて、3本の桟の強度を設定したならば、各桟を共通化することができても、各桟が重くなって、コストも高くなる。   If the strength of the three bars is set in accordance with the large load applied to the central bar, even if the bars can be shared, the bars become heavy and the cost increases.

補強部材は、中央の桟の桟部材の一端部に付設されるだけでよい。補強部材を桟部材の両端部に付設すると、補強部材の個数が多くなって、施工作業が煩雑になり、コストが高くなる。例えば、補強部材は、トラス構造を有するものでよい。   The reinforcing member only needs to be attached to one end portion of the crosspiece member of the central crosspiece. If the reinforcing members are attached to both ends of the crosspiece member, the number of reinforcing members increases, and the construction work becomes complicated and the cost increases. For example, the reinforcing member may have a truss structure.

また、中央の桟だけに、桟の長手方向に沿って該桟の中央付近に重ねられて固定される補強具を設けることによっても、中央の桟を補強することができる。   Further, the central rail can be reinforced only by providing a reinforcing tool that is superposed and fixed in the vicinity of the center of the rail along the longitudinal direction of the rail only in the central rail.

更に、この補強具を構造物を桟に連結接続するために兼用すれば、部品点数の増大を抑えることができる。   Furthermore, if this reinforcing tool is also used to connect the structure to the crosspiece, an increase in the number of parts can be suppressed.

次に、他の本発明の構造物設置用架台では、並設された各ベース桟と、各ベース桟の一端にそれぞれ突設された各アームと、各ベース桟の他端と各アームの上端にそれぞれ架け渡され固定された各縦桟と、各縦桟と直交するように配されて、該各縦桟上に並設され、各構造物が搭載されて配列される各横桟とを備え、各横桟は、上記桟部材を複数接続したものである。従って、横桟の強度が高く、また複数の桟部材の接続により横桟を容易に延長することができ、施工作業が容易である。   Next, in another structure installation stand of the present invention, the base rails arranged in parallel, the arms protruding from one end of each base rail, the other end of each base rail, and the upper end of each arm Each vertical beam spanned and fixed to the vertical beam, and each horizontal beam arranged so as to be orthogonal to each vertical beam, arranged in parallel on each vertical beam, and on which each structure is mounted and arranged Each horizontal rail is formed by connecting a plurality of the rail members. Therefore, the strength of the horizontal beam is high, and the horizontal beam can be easily extended by connecting a plurality of beam members, so that the construction work is easy.

また、各桟部材だけでなく、各ベース桟、各アーム、および、各縦桟も上記桟部材と同一断面を含む部材からなる。このため、ベース桟、アーム、及び縦桟の異なる種類の桟を接続させて架台を構成する際に、桟の各側板端部を他の桟の各側板端部の外側又は内側に重ねて、端部同士を接続することが可能になり、施工作業を単純化することができる。   Moreover, not only each crosspiece member but also each base crosspiece, each arm, and each vertical crosspiece is made of a member having the same cross section as the crosspiece member. For this reason, when configuring a base by connecting different types of base rails, arms, and vertical rails, overlap each side plate end of the beam on the outside or inside of each side plate end, It becomes possible to connect ends, and construction work can be simplified.

更に、各横桟、各ベース桟、各アーム、及び各縦桟の断面形状をハット型断面とし、それらの強度の向上を図ってもよい。   Furthermore, the cross-sectional shape of each horizontal crosspiece, each base crosspiece, each arm, and each vertical crosspiece may be a hat-shaped cross section to improve their strength.

また、各横桟、各ベース桟、各アーム、及び各縦桟の桟部材をロールフォーミング加工により形成して、桟部材の大量生産によるコストの低減を図ってもよい。   Moreover, the crosspieces of the horizontal crosspieces, the base crosspieces, the arms, and the vertical crosspieces may be formed by roll forming to reduce the cost by mass production of the crosspiece members.

次に、本発明の施工方法では、各桟部材の一方の各側板端部を他方の各側板端部の内側又は外側に重ねた後、一方の各側板端部と他方の各側板端部を接続しているので、桟を延長するべく、桟部材の本数を増やしても、そのような接続作業を繰り返すだけであって、施工作業が容易である。   Next, in the construction method of the present invention, after each side plate end of each crosspiece member is overlapped inside or outside of the other side plate end, one side plate end and the other side plate end are Since they are connected, even if the number of crosspiece members is increased in order to extend the crosspiece, only such connection work is repeated, and the construction work is easy.

次に、本発明の太陽電池システムでは、上記本発明の構造物設置用架台の横桟上に構造物としての太陽電池モジュールを搭載している。太陽電池モジュールが平板状であって傾斜して配置されることから、太陽電池モジュールの表裏に大きな風圧がかかり易い。このため、上記本発明の構造物設置用架台は、太陽電池システムの架台として好適である。   Next, in the solar cell system of the present invention, a solar cell module as a structure is mounted on the horizontal rail of the structure installation stand of the present invention. Since the solar cell module has a flat plate shape and is inclined, a large wind pressure is likely to be applied to the front and back of the solar cell module. For this reason, the structure installation stand of the present invention is suitable as a stand for a solar cell system.

以下、本発明の実施形態を添付図面を参照しつつ詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

図1は、本発明の構造物設置用架台の一実施形態を適用した太陽電池システムを示す斜視図である。また、図2は図1の太陽電池システムを示す背面図であり、図3は図1の太陽電池システムを部分的に拡大して示す斜視図である。   FIG. 1 is a perspective view showing a solar cell system to which an embodiment of a structure installation stand of the present invention is applied. 2 is a rear view showing the solar cell system of FIG. 1, and FIG. 3 is a partially enlarged perspective view of the solar cell system of FIG.

この太陽電池システムでは、大規模な発電所の実現を前提としており、本実施形態の構造物設置用架台を用いて、多数の太陽電池モジュールを設置している。   This solar cell system is premised on the realization of a large-scale power plant, and a large number of solar cell modules are installed using the structure installation stand of this embodiment.

図1、図2、及び図3に示すように本実施形態の構造物設置用架台では、複数のコンクリート基礎11を等間隔に地面上に敷設し、各コンクリート基礎11の上面11-1にそれぞれのベース桟12を固定して、これらのベース桟12を等間隔に並設し、各ベース桟12の後端部12-1にそれぞれのアーム13を接続して立設し、各ベース12の先端部12-2と各アーム13の上端部13-1にそれぞれの縦桟14を斜めに架け渡して固定し、3本の横桟15を各縦桟14と直交するように配して、各横桟15を各縦桟14上に並設している。また、図1において最も右側のベース桟12を1番目とすると、偶数番目のベース桟12毎に、ベース桟12と中央の横桟15間に2本のトラス16を架け渡して、中央の横桟15を補強するためのトラス構造を構築している。   As shown in FIGS. 1, 2, and 3, in the structure installation stand of the present embodiment, a plurality of concrete foundations 11 are laid on the ground at equal intervals, and are respectively placed on the upper surface 11-1 of each concrete foundation 11. The base bars 12 are fixed, the base bars 12 are arranged in parallel at equal intervals, the respective arms 13 are connected to the rear ends 12-1 of the base bars 12, and the base bars 12 are erected. Each vertical beam 14 is obliquely bridged and fixed to the front end 12-2 and the upper end 13-1 of each arm 13, and three horizontal beams 15 are arranged so as to be orthogonal to each vertical beam 14, Each horizontal beam 15 is juxtaposed on each vertical beam 14. Further, assuming that the rightmost base beam 12 is the first in FIG. 1, two truss 16 are bridged between the base beam 12 and the central horizontal beam 15 for each even-numbered base beam 12, and A truss structure for reinforcing the crosspiece 15 is constructed.

尚、図1、図2、及び図3においては、各コンクリート基礎11が並ぶ方向をX方向(左右方向)とし、このX方向と直交する方向をY方向(前後方向)としている。   1, 2, and 3, the direction in which the concrete foundations 11 are arranged is the X direction (left-right direction), and the direction orthogonal to the X direction is the Y direction (front-rear direction).

このような構成の構造物設置用架台において、上側の横桟15と中央の横桟15に複数の太陽電池モジュール17を横一列に並べて搭載し、下側の横桟15と中央の横桟15にも複数の太陽電池モジュール17を横一列に並べて搭載している。従って、3本の横桟15上に、複数の太陽電池モジュール17が2列に並べて搭載されている。また、左右に隣合う2本の縦桟14間に、6枚の太陽電池モジュール17が割り振られている。太陽電池モジュール17は、複数の太陽電池セルを行列方向に配置してなる太陽電池パネル18を枠部材19により保持したものである。   In the structure installation stand having such a configuration, a plurality of solar cell modules 17 are mounted side by side on the upper horizontal beam 15 and the central horizontal beam 15, and the lower horizontal beam 15 and the central horizontal beam 15 are mounted. In addition, a plurality of solar cell modules 17 are mounted in a horizontal row. Accordingly, a plurality of solar cell modules 17 are arranged in two rows on the three horizontal rails 15. In addition, six solar cell modules 17 are allocated between two vertical bars 14 adjacent to the left and right. The solar cell module 17 is obtained by holding a solar cell panel 18 in which a plurality of solar cells are arranged in a matrix direction by a frame member 19.

次に、構造物設置用架台を構成するコンクリート基礎11、ベース桟12、アーム13、縦桟14、横桟15、トラス16等について説明する。   Next, the concrete foundation 11, the base beam 12, the arm 13, the vertical beam 14, the horizontal beam 15, the truss 16 and the like constituting the structure installation stand will be described.

各コンクリート基礎11は、地面上に型枠を形成し、この型枠にコンクリートを流し込んで固めたものである。各コンクリート基礎11は、等間隔に配置され、それらの上面11-1が水平かつ同一高さで面一となっている。   Each concrete foundation 11 is formed by forming a mold on the ground and pouring concrete into the mold. The concrete foundations 11 are arranged at equal intervals, and their upper surfaces 11-1 are horizontal and flush with each other.

これらのコンクリート基礎11の上面11-1が水平な基礎面として用いられ、この基礎面上に各ベース桟12が等間隔にかつ平行に固定され、更に各ベース桟12、各アーム13、各縦桟14、各横桟15、及び各トラス16等が組立てられ接続されて、構造物設置用架台が構築されている。勿論、複数のコンクリート基礎11の代わりに、コンクリートを架台の設置域全体に一様に流し込んでなるベタ基礎など他の構造の基礎を適用しても構わない。   The upper surface 11-1 of the concrete foundation 11 is used as a horizontal foundation surface, and the base rails 12 are fixed on the foundation surface at equal intervals and in parallel. Further, the base rails 12, the arms 13, and the vertical bars are fixed. The crosspiece 14, the horizontal crosspieces 15, the truss 16 and the like are assembled and connected to construct a structure installation stand. Of course, instead of the plurality of concrete foundations 11, a foundation of another structure such as a solid foundation in which concrete is uniformly poured into the entire installation area of the gantry may be applied.

図4は、ベース桟12を示す斜視図である。図4に示すようにベース桟12は、相互に対向する一対の側板12a、各側板12aの対向一辺を連結する主板12b、及び各側板12aの縁で外側に折り曲げられたそれぞれの鍔12cからなるハット型断面形状を有している。ベース桟12の先端部12-2では各鍔12cが切除され、このベース桟12の先端部12-2が各側板12a及び主板12bからなるコの字型断面形状となっている。   FIG. 4 is a perspective view showing the base bar 12. As shown in FIG. 4, the base crosspiece 12 is composed of a pair of side plates 12a facing each other, a main plate 12b connecting the opposite sides of each side plate 12a, and respective flanges 12c bent outward at the edges of each side plate 12a. It has a hat-shaped cross-sectional shape. Each flange 12c is cut off at the front end portion 12-2 of the base crosspiece 12, and the front end portion 12-2 of the base crosspiece 12 has a U-shaped cross-sectional shape including the side plates 12a and the main plate 12b.

このベース桟12の主板12bの両端近傍にはそれぞれの長形孔12dが形成され、各側板12aの両端部にはそれぞれのボルト孔12eが形成され、各鍔12cの中央部にはそれぞれのボルト孔12fが形成されている。   Long holes 12d are formed in the vicinity of both ends of the main plate 12b of the base bar 12, bolt holes 12e are formed in both ends of each side plate 12a, and each bolt 12c is formed in the center of each flange 12c. A hole 12f is formed.

図5は、アーム13を示す斜視図及び平面図である。図5に示すようにアーム13は、相互に対向する一対の側板13a、各側板13aの対向一辺を連結する主板13b、及び各側板13aの縁で外側に折り曲げられたそれぞれの鍔13cからなるハット型断面形状を有している。アーム13の下端部13-2では主板13b及び各鍔13cが切除されて、各側板13aだけが残されている。また、アーム13の上端部13-1でも主板13b及び各鍔13cが切除され、各側板13aだけが残されている。更に、アーム13の各側板13aの両端部にはそれぞれのボルト孔13dが形成されている。   FIG. 5 is a perspective view and a plan view showing the arm 13. As shown in FIG. 5, the arm 13 includes a pair of side plates 13 a facing each other, a main plate 13 b that connects opposite sides of each side plate 13 a, and a hat 13 c that is bent outward at the edge of each side plate 13 a. It has a mold cross-sectional shape. At the lower end 13-2 of the arm 13, the main plate 13b and the flanges 13c are cut away, leaving only the side plates 13a. Further, the main plate 13b and the flanges 13c are also cut off at the upper end portion 13-1 of the arm 13, and only the side plates 13a are left. Further, respective bolt holes 13 d are formed at both ends of each side plate 13 a of the arm 13.

図6(a)及び(b)は、縦桟14を示す斜視図及び平面図である。図6に示すように縦桟14は、相互に対向する一対の側板14a、各側板14aの対向一辺を連結する主板14b、及び各側板14aの縁で外側に折り曲げられたそれぞれの鍔14cからなるハット型断面形状を有している。   FIGS. 6A and 6B are a perspective view and a plan view showing the vertical rail 14. As shown in FIG. 6, the vertical rail 14 is composed of a pair of side plates 14a facing each other, a main plate 14b connecting the opposing sides of the side plates 14a, and respective flanges 14c bent outward at the edges of the side plates 14a. It has a hat-shaped cross-sectional shape.

この縦桟14の主板14bの両端近傍及び中央には、一対のT字形孔14dがそれぞれ形成されている。また、各側板14aの先端部にはそれぞれのボルト孔14eが形成され、各側板14aの中央部から後端部寄りの部位にもそれぞれのボルト孔14eが形成されている。   A pair of T-shaped holes 14d are formed in the vicinity of the both ends and the center of the main plate 14b of the vertical beam 14, respectively. Further, each bolt 14e is formed at the front end of each side plate 14a, and each bolt hole 14e is also formed at a position near the rear end from the center of each side plate 14a.

図7(a)、(b)及び図8は、横桟15を構成する桟部材を示している。図1に示すように横桟15がX方向に極めて長く、横桟15を単一の部材で構成するのは不可能であるため、横桟15を複数の桟部材を接続して構成している。   FIGS. 7A, 7 </ b> B, and 8 illustrate a crosspiece member that forms the horizontal crosspiece 15. As shown in FIG. 1, the horizontal beam 15 is extremely long in the X direction, and it is impossible to configure the horizontal beam 15 with a single member. Therefore, the horizontal beam 15 is configured by connecting a plurality of beam members. Yes.

図7(a)及び(b)は、図1において横桟15の最も右側の桟部材151を1番目とすると、この1番目の桟部材151を示す斜視図及び平面図である。図7に示すように1番目の桟部材151は、相互に対向する一対の側板15a、各側板15aの対向一辺を連結する主板15b、及び各側板15aの縁で外側に折り曲げられたそれぞれの鍔15cからなるハット型断面形状を有している。換言すれば、桟部材151は、各側板15aの長手方向に延びる各辺が主板15bにより連結され、各鍔15cがそれぞれの側板15aから外側に突出した形状を有する。   FIGS. 7A and 7B are a perspective view and a plan view showing the first crosspiece member 151 when the rightmost crosspiece member 151 of the horizontal crosspiece 15 in FIG. As shown in FIG. 7, the first crosspiece 151 includes a pair of side plates 15 a facing each other, a main plate 15 b that connects opposite sides of each side plate 15 a, and each ridge bent outward at the edge of each side plate 15 a. It has a hat-shaped cross section consisting of 15c. In other words, the crosspiece member 151 has a shape in which the sides extending in the longitudinal direction of the side plates 15a are connected by the main plate 15b, and the flanges 15c protrude outward from the side plates 15a.

この桟部材151の主板15bの4箇所には、一対のスリット15dとボルト孔15eがそれぞれ形成されている。更に、各側板15aの複数箇所にそれぞれのボルト孔15fが形成され、各鍔15cの両端部にはそれぞれの長形孔15gが形成されている。   A pair of slits 15d and bolt holes 15e are formed at four locations on the main plate 15b of the crosspiece 151, respectively. Further, bolt holes 15f are formed at a plurality of locations on each side plate 15a, and respective elongated holes 15g are formed at both ends of each flange 15c.

また、桟部材151の長さは、図1に示す各縦桟14の間隔よりも僅かに長くされ、桟部材151を各縦桟14間に架け渡すことが可能にされている。   Further, the length of the crosspiece member 151 is slightly longer than the interval between the vertical crosspieces 14 shown in FIG. 1 so that the crosspiece member 151 can be bridged between the vertical crosspieces 14.

図8は、図1において最も右側の桟部材151を1番目とすると、この1番目よりも左側の2番目以降の桟部材152を示す斜視図である。図8に示すように2番目以降の桟部材152も、図7の桟部材151と同様に、一対の側板15a、主板15b、及び各鍔15cからなるハット型断面形状を有している。また、主板15bの3箇所に一対のスリット15dとボルト孔15eがそれぞれ形成され、各側板15aの複数箇所にそれぞれのボルト孔15fが形成され、各鍔15cの一端部にそれぞれの長形孔15gが形成されている。   FIG. 8 is a perspective view showing the second and subsequent beam members 152 on the left side of the first when the rightmost beam member 151 is the first in FIG. As shown in FIG. 8, the second and subsequent crosspiece members 152 also have a hat-shaped cross-sectional shape including a pair of side plates 15a, a main plate 15b, and respective flanges 15c, similarly to the crosspiece member 151 of FIG. Also, a pair of slits 15d and bolt holes 15e are formed at three locations on the main plate 15b, bolt holes 15f are formed at a plurality of locations on each side plate 15a, and each elongated hole 15g is formed at one end of each flange 15c. Is formed.

更に、桟部材152の片側端部152-1で主板15b及び各側板15aの一辺に沿う部分が切除され、各側板15a及び各鍔15cだけが残されている。   Furthermore, a portion along one side of the main plate 15b and each side plate 15a is cut off at one end portion 152-1 of the crosspiece member 152, so that only the side plates 15a and the flanges 15c are left.

また、桟部材152の長さは、図1に示す各縦桟14の間隔と略同一であって、桟部材151よりも僅かに短くされている。   Moreover, the length of the crosspiece member 152 is substantially the same as the interval between the vertical crosspieces 14 shown in FIG. 1, and is slightly shorter than the crosspiece member 151.

図9は、トラス16を示す斜視図である。図9に示すようにトラス16は、相互に対向する一対の側板16a、各側板16aの対向一辺を連結する主板16b、及び各側板16aの縁で外側に折り曲げられたそれぞれの鍔16cからなるハット型断面形状を有している。   FIG. 9 is a perspective view showing the truss 16. As shown in FIG. 9, the truss 16 includes a pair of side plates 16 a facing each other, a main plate 16 b that connects opposite sides of each side plate 16 a, and a hat 16 c that is bent outward at the edge of each side plate 16 a. It has a mold cross-sectional shape.

このトラス16の一端部16-1では主板16b及び各鍔16cが切除されて、各側板16aだけが残されている。また、トラス16の他端部16-2でも主板16b及び各鍔16cが切除され、各側板16aだけが残されている。更に、トラス16の各側板16aの両端部にはそれぞれのボルト孔16dが形成されている。   At one end portion 16-1 of the truss 16, the main plate 16b and the flanges 16c are cut away, leaving only the side plates 16a. Further, the main plate 16b and the flanges 16c are also cut off at the other end portion 16-2 of the truss 16, leaving only the side plates 16a. Further, respective bolt holes 16 d are formed at both ends of each side plate 16 a of the truss 16.

ここで、ベース桟12、アーム13、縦桟14、横桟15、及びトラス16のいずれも、各側板、各側板の対向一辺を連結する主板、及び各側板の縁で外側に折り曲げられたそれぞれの鍔からなるハット型断面形状を有している。また、いずれのハット型断面形状も同一サイズである。換言すれば、主板の幅及び側板の幅が同一である。更に、いずれも、同一厚さのメッキ鋼板を切断もしくは孔開け加工した後、メッキ鋼板を折り曲げ加工して形成される。このため、材料及び加工装置を共通化することができ、コストの大幅な低減を図ることができる。   Here, each of the base rail 12, the arm 13, the vertical rail 14, the horizontal rail 15, and the truss 16 is bent outward at each side plate, a main plate that connects opposite sides of each side plate, and an edge of each side plate. It has a hat-shaped cross-sectional shape consisting of Moreover, all hat-shaped cross-sectional shapes are the same size. In other words, the width of the main plate and the width of the side plate are the same. Further, both are formed by cutting or punching a plated steel sheet having the same thickness and then bending the plated steel sheet. For this reason, the material and the processing apparatus can be shared, and the cost can be significantly reduced.

更に、メッキ鋼板をハット型断面形状に成型するためにロールフォーミング加工を適用することができる。この場合は、大量生産を迅速に行うことができ、コストをより大幅に低減させることができる。先に述べたように本実施形態の構造物設置用架台が適用される太陽電池システムは、大規模な発電所の実現が前提となっているので、太陽電池モジュールの枚数が極めて多く、架台の規模も大きい。このため、ベース桟12、アーム13、縦桟14、横桟15、及びトラス16の使用数が多く、これらを迅速に大量生産するには、これらの断面形状及びサイズを同一にして、ロールフォーミング加工を適用するのがよく、この結果としてコストの大幅な低減を可能にしている。   Furthermore, roll forming can be applied to form a plated steel sheet into a hat-shaped cross-sectional shape. In this case, mass production can be performed quickly, and the cost can be further greatly reduced. As described above, since the solar cell system to which the structure installation platform of the present embodiment is applied is premised on the realization of a large-scale power plant, the number of solar cell modules is extremely large. The scale is also large. For this reason, the base beam 12, the arm 13, the vertical beam 14, the horizontal beam 15, and the truss 16 are used in large numbers, and in order to rapidly mass-produce them, roll forming is performed with the same cross-sectional shape and size. Processing is often applied, resulting in a significant cost reduction.

また、ベース桟12、アーム13、縦桟14、横桟15、及びトラス16のハット型断面形状は、図10に示すように各側板aの間隔が主板bから離れるほど広くなるように主板aに対する各側板aの折り曲げ角度αを設定した形状である。つまり、桟のハット型断面形状の開口部側で各側板aが広がって、桟の開口部よりも主板bの方の幅が狭くなっている。このため、後で述べるように桟端部の各側板を他の桟端部に重ねるという施工作業が容易になる。   Further, as shown in FIG. 10, the hat-shaped cross-sectional shapes of the base rail 12, the arm 13, the vertical rail 14, the horizontal rail 15, and the truss 16 are such that the distance between the side plates a increases as the distance from the main plate b increases. Is a shape in which the bending angle α of each side plate a is set. That is, each side plate a spreads on the opening side of the cross-sectional hat shape of the crosspiece, and the width of the main plate b is narrower than the opening portion of the crosspiece. For this reason, as will be described later, the construction work of stacking each side plate of the crosspiece end on the other crosspiece end becomes easy.

次に、コンクリート基礎11上に、ベース桟12、アーム13、及び縦桟14を組立ててなる三角構造について説明する。   Next, a triangular structure in which the base beam 12, the arm 13, and the vertical beam 14 are assembled on the concrete foundation 11 will be described.

図11(a)、(b)は、ベース桟12、アーム13、及び縦桟14からなる三角構造を示す斜視図及び正面図である。図11に示すようにコンクリート基礎11の上面11-1にベース桟12を固定し、ベース桟12の後端部12-1にアーム13を接続して立設し、ベース12の先端部12-2とアーム13の上端部13-1に縦桟14を斜めに架け渡して固定し、ベース桟12、アーム13、及び縦桟14からなる三角構造を構築している。   FIGS. 11A and 11B are a perspective view and a front view showing a triangular structure composed of a base beam 12, an arm 13, and a vertical beam 14, respectively. As shown in FIG. 11, the base beam 12 is fixed to the upper surface 11-1 of the concrete foundation 11, and the arm 13 is connected to the rear end portion 12-1 of the base beam 12 so as to stand upright. 2 and an upper end portion 13-1 of the arm 13 are fixed to the vertical beam 14 in an oblique manner, and a triangular structure including the base beam 12, the arm 13, and the vertical beam 14 is constructed.

コンクリート基礎11の上面11-1には2本のボルト21を予め突設しており、これらのボルト21をベース桟12の主板12bの各長形孔12dに挿し通して、ベース桟12の主板12bをコンクリート基礎11の上面11-1に当接させて、ベース桟12を載置する。このとき、ベース桟12並びに各ボルト21を各長形孔12dに沿って(図1のY方向に)移動させることができるので、ベース桟12をY方向に移動させて、Y方向の位置を調節する。   Two bolts 21 are projected in advance on the upper surface 11-1 of the concrete foundation 11, and these bolts 21 are inserted into the respective elongated holes 12d of the main plate 12b of the base bar 12 so as to pass through the main plate of the base bar 12. The base bar 12 is placed with the surface 12b brought into contact with the upper surface 11-1 of the concrete foundation 11. At this time, the base rail 12 and the bolts 21 can be moved along the long holes 12d (in the Y direction in FIG. 1), so that the base rail 12 is moved in the Y direction to adjust the position in the Y direction. Adjust.

図12は、ベース桟12の固定に用いられるコの字型補強金具22を示す斜視図である。このコの字型補強金具22は、主板22aと、主板22aの両縁で折り曲げられたそれぞれの側板22bとを有しており、主板22aの中央にボルト孔22cが形成されている。   FIG. 12 is a perspective view showing a U-shaped reinforcing bracket 22 used for fixing the base rail 12. The U-shaped reinforcing metal fitting 22 has a main plate 22a and side plates 22b bent at both edges of the main plate 22a, and a bolt hole 22c is formed at the center of the main plate 22a.

このようなコの字型補強金具22を2個用いる。ベース桟12の主板12bをコンクリート基礎11の上面11-1に載置した後、2個のコの字型補強金具22の孔にそれぞれのボルト21を通して、各コの字型補強金具22をベース桟12の内側に配置する。このとき、図13に示すようにコの字型補強金具22の各側板22bがベース桟12の各側板12aと直交するようにコの字型補強金具22の向きを設定し、コの字型補強金具22の各側板22bをベース桟12の主板12bに当接させる。そして、各ボルト21にそれぞれのナットをねじ込んで締め込み、これによりベース桟12をコンクリート基礎11の上面11-1に固定する。   Two such U-shaped reinforcing brackets 22 are used. After the main plate 12b of the base rail 12 is placed on the upper surface 11-1 of the concrete foundation 11, the respective U-shaped reinforcing brackets 22 are inserted into the holes of the two U-shaped reinforcing brackets 22 through the respective bolts 21. Arranged inside the crosspiece 12. At this time, as shown in FIG. 13, the direction of the U-shaped reinforcing bracket 22 is set so that each side plate 22 b of the U-shaped reinforcing bracket 22 is orthogonal to each side plate 12 a of the base bar 12. Each side plate 22b of the reinforcing bracket 22 is brought into contact with the main plate 12b of the base bar 12. Then, each nut 21 is screwed and tightened, whereby the base bar 12 is fixed to the upper surface 11-1 of the concrete foundation 11.

この状態では、コの字型補強金具22の各側板22bがベース桟12の主板12bに圧接して、ベース桟12の主板12bが補強される。また、コの字型補強金具22の各側板22bの幅がベース桟12の各側板12aの間隔と略同一に設定されていることから、ベース桟12の各側板12aが補強される。   In this state, the side plates 22b of the U-shaped reinforcing metal fitting 22 are pressed against the main plate 12b of the base beam 12, and the main plate 12b of the base beam 12 is reinforced. Further, since the width of each side plate 22b of the U-shaped reinforcing metal fitting 22 is set to be substantially the same as the interval between the side plates 12a of the base bar 12, each side plate 12a of the base bar 12 is reinforced.

この後、ベース桟12の後端部12-1にアーム13を接続して立設する。アーム13の下端部13-2では主板13b及び各鍔13cが切除されて、各側板13aだけが残されている。また、図10に示すようにベース桟12の各側板12aがハット型断面形状の開口部側で広がっている。このため、各側板13aの下端部を相互に接近するように弾性変形させつつ、ベース桟12の各側板12aの後端部内側に各側板13aの下端部を容易に差し込んで挟み込むことができ、各側板13aの下端部と各側板12aの後端部を重ね合わせることができる。このとき、アーム13が自立し、引き続くアーム13の接続作業が容易になる。   Thereafter, the arm 13 is connected to the rear end portion 12-1 of the base bar 12 and is erected. At the lower end 13-2 of the arm 13, the main plate 13b and the flanges 13c are cut away, leaving only the side plates 13a. Moreover, as shown in FIG. 10, each side plate 12a of the base crosspiece 12 spreads on the opening side of the hat-shaped cross section. For this reason, while elastically deforming the lower end portions of the side plates 13a so as to approach each other, the lower end portions of the side plates 13a can be easily inserted and sandwiched inside the rear end portions of the side plates 12a of the base bar 12, The lower end of each side plate 13a and the rear end of each side plate 12a can be overlapped. At this time, the arm 13 is self-supporting, and the subsequent connection work of the arm 13 is facilitated.

このアーム13が自立した状態で、図13に示すようにアーム13の各側板13a間にパイプ25を挿入して、パイプ25、アーム13の各側板13aのボルト孔13d、及びベース桟12の各側板12aのボルト孔12eを位置合わせし、ボルト26をパイプ25、アーム13の各側板13aのボルト孔13d、ベース桟12の各側板12aのボルト孔12e、及びワッシャに通して、ボルト26の一端にナット27をねじ込んで締め込み、アーム13の各側板13aの下端部をベース桟12の各側板12aに接続する。   In a state where the arm 13 is self-supporting, a pipe 25 is inserted between the side plates 13a of the arm 13 as shown in FIG. 13, and the pipe 25, the bolt holes 13d of the side plates 13a of the arm 13 and the base rails 12 are The bolt hole 12e of the side plate 12a is aligned, and the bolt 26 is passed through the pipe 25, the bolt hole 13d of each side plate 13a of the arm 13, the bolt hole 12e of each side plate 12a of the base rail 12, and the washer. A nut 27 is screwed into and tightened to connect the lower end of each side plate 13 a of the arm 13 to each side plate 12 a of the base bar 12.

このようにボルト26を、パイプ25、アーム13の各側板13a、及びベース桟12の各側板12aに通して、ナット27を締めこむと、パイプ25が各側板13a、12a間に挟みこまれて、該各側板が補強され、アーム13及びベース桟12のハット型断面形状(図10に示す)の変形を防ぐことができる。また、パイプ25の長さと桟の各側板間の離間距離が等しく、ナット等と比較して、パイプ25のサイズが大きいため手作業での施工性が向上する。また、パイプ25、ボルト26、及びナット27等を1個ずつ用いるだけであるから、部品点数、工数、及びコストを低減させることができる。   In this way, when the bolt 26 is passed through the pipe 25, the side plates 13a of the arm 13 and the side plates 12a of the base bar 12, and the nut 27 is tightened, the pipe 25 is sandwiched between the side plates 13a and 12a. The side plates are reinforced, and the deformation of the hat-shaped cross-sectional shape (shown in FIG. 10) of the arm 13 and the base bar 12 can be prevented. Further, since the length of the pipe 25 and the distance between the side plates of the crosspiece are equal and the size of the pipe 25 is larger than that of a nut or the like, the workability by manual work is improved. Moreover, since only the pipe 25, the bolt 26, the nut 27, etc. are used one by one, the number of parts, a man-hour, and cost can be reduced.

次に、ベース12の先端部12-2とアーム13の上端部13-1に縦桟14を斜めに架け渡して固定する。ベース桟12の先端部では各鍔12cが切除されている。また、図10に示すように縦桟14の各側板14aがハット型断面形状の開口部側で広がっている。このため、ベース桟12の各側板12aの先端部を相互に接近するように弾性変形させつつ縦桟14の各側板14aの先端部内側に容易に差し込むことができ、各側板12aの先端部と各側板14aの先端部を重ね合わせることができる。   Next, the vertical beam 14 is bridged obliquely between the tip portion 12-2 of the base 12 and the upper end portion 13-1 of the arm 13 and fixed. Each ridge 12c is cut off at the tip of the base bar 12. Further, as shown in FIG. 10, each side plate 14a of the vertical beam 14 spreads on the opening side of the hat-shaped cross section. For this reason, the tip of each side plate 12a of the base beam 12 can be easily inserted into the inside of the tip of each side plate 14a of the vertical beam 14 while being elastically deformed so as to approach each other. The front ends of the side plates 14a can be overlapped.

この状態で、図13と同様に、ベース桟12の各側板12a間にパイプを挿入して、パイプ、ベース桟12の各側板12aのボルト孔12e、及び縦桟14の各側板14aのボルト孔14eを位置合わせし、ボルトをパイプ、ベース桟12の各側板12aのボルト孔12e、縦桟14の各側板14aのボルト孔14e、及びワッシャに通して、ボルトの一端にナットをねじ込んで締め込み、縦桟14の各側板14aの先端部をベース桟12の各側板12aに接続する。   In this state, as in FIG. 13, pipes are inserted between the side plates 12 a of the base beam 12, and the pipes, the bolt holes 12 e of the side plates 12 a of the base beam 12, and the bolt holes of the side plates 14 a of the vertical beam 14. 14e is aligned, the bolt is passed through the pipe, the bolt hole 12e of each side plate 12a of the base beam 12, the bolt hole 14e of each side plate 14a of the vertical beam 14, and the washer, and a nut is screwed into one end of the bolt and tightened. The front ends of the side plates 14 a of the vertical beam 14 are connected to the side plates 12 a of the base beam 12.

同様に、アーム13の上端部13-1でも、主板13b及び各鍔13cが切除されて、各側板13aだけが残されているため、各側板13aの上端部を相互に接近するように弾性変形させつつ、各側板13aの上端部を縦桟14の各側板14aの内側に差し込むことができる。   Similarly, at the upper end 13-1 of the arm 13, since the main plate 13b and the flanges 13c are cut away and only the side plates 13a are left, the upper end portions of the side plates 13a are elastically deformed so as to approach each other. The upper end portion of each side plate 13a can be inserted into the inside of each side plate 14a of the vertical rail 14 while making it happen.

この状態で、図13と同様に、アーム13の各側板13a間にパイプを挿入して、パイプ、アーム13の各側板13aのボルト孔13d、及び縦桟14の各側板14aのボルト孔14eを位置合わせし、ボルトをパイプ、アーム13の各側板13aのボルト孔13d、縦桟14の各側板14aのボルト孔14e、及びワッシャに通して、ボルトの一端にナットをねじ込んで締め込み、アーム13の上端部13-1を縦桟14の各側板14aに接続する。   In this state, as in FIG. 13, a pipe is inserted between the side plates 13 a of the arm 13, and the bolt holes 13 d of the side plates 13 a of the arm 13 and the bolt holes 14 e of the side plates 14 a of the vertical beam 14 are formed. The bolts are passed through pipes, bolt holes 13d of the side plates 13a of the arm 13, bolt holes 14e of the side plates 14a of the vertical rails 14, and washers. A nut is screwed into one end of the bolt and tightened. Are connected to the side plates 14a of the vertical beam 14 respectively.

このようにしてベース桟12、アーム13、及び縦桟14からなる三角構造を構築している。この三角構造では、格別に部品点数を増やさなくても、垂直方向及び水平方向のいずれの力にも十分に耐えることができる。   In this way, a triangular structure including the base beam 12, the arm 13, and the vertical beam 14 is constructed. This triangular structure can sufficiently withstand both the vertical and horizontal forces without particularly increasing the number of parts.

次に、横桟15を構成する桟部材151、52を縦桟14に接続固定するための構造について説明する。   Next, a structure for connecting and fixing the beam members 151 and 52 constituting the horizontal beam 15 to the vertical beam 14 will be described.

図14は、横桟15の桟部材151、52を縦桟14に接続固定するのに用いられる取付け金具31を示す斜視図である。この取付け金具31は、主板31aに2つのネジ孔31bを形成し、主板31aの両側に側板31cを設け、また主板31aの前後にも側板31dを設けて2重に折り曲げ、各側板31dの中央からそれぞれのT字型の支持片31eを突出させたものである。   FIG. 14 is a perspective view showing a mounting bracket 31 used for connecting and fixing the crosspiece members 151 and 52 of the horizontal crosspiece 15 to the vertical crosspiece 14. The mounting bracket 31 is formed with two screw holes 31b in the main plate 31a, side plates 31c on both sides of the main plate 31a, side plates 31d on the front and rear sides of the main plate 31a, and a double bend. Each T-shaped support piece 31e is protruded from.

図6及び図11に示すように縦桟14の主板14bの両端近傍及び中央には、一対のT字形孔14dがそれぞれ形成されている。この一対のT字形孔14d毎に、取付け金具31を縦桟14の主板14bに取付け、縦桟14の主板14bの中央及び両端近傍の3箇所にそれぞれの取付け金具31を配置する。   As shown in FIGS. 6 and 11, a pair of T-shaped holes 14 d are formed in the vicinity of both ends and the center of the main plate 14 b of the vertical rail 14. For each pair of T-shaped holes 14d, the mounting bracket 31 is mounted on the main plate 14b of the vertical beam 14, and the respective mounting brackets 31 are arranged at three locations near the center and both ends of the main plate 14b of the vertical beam 14.

図15に示すように取付け金具31の各支持片31eの頭部をそれぞれのT字形孔14dのスリット14fに挿し込み、各支持片31eをそれぞれのT字形孔14dの係合孔14gへと移動させて、各支持片31eの頭部をそれぞれのT字形孔14dの係合孔14gに引っ掛けて、取付け金具31を縦桟14の主板14bに取付ける。   As shown in FIG. 15, the head of each support piece 31e of the mounting bracket 31 is inserted into the slit 14f of each T-shaped hole 14d, and each support piece 31e is moved to the engagement hole 14g of each T-shaped hole 14d. Then, the mounting bracket 31 is attached to the main plate 14b of the vertical beam 14 by hooking the heads of the respective support pieces 31e into the engagement holes 14g of the respective T-shaped holes 14d.

図1及び図16に示すように桟部材151、152を縦桟14と直交するように該縦桟14の主板14b上に載せ、桟部材151、152の各鍔15cを取付け金具31の各支持片31eの頭部間に配置する。そして、桟部材151、152の各鍔15cの長形孔15gを縦桟14の主板14bの各T字形孔14dを介して取付け金具31の各ネジ孔31bに重ね、各ボルト32を桟部材151、152の各鍔15cの長形孔15g及び縦桟14の主板14bの各T字形孔14dを介して取付け金具31の各ネジ孔31bにねじ込んで仮止めする。   1 and 16, the beam members 151 and 152 are placed on the main plate 14b of the vertical beam 14 so as to be orthogonal to the vertical beam 14, and the flanges 15c of the beam members 151 and 152 are supported by the mounting bracket 31. It arrange | positions between the heads of the piece 31e. The elongated holes 15g of the flanges 15c of the crosspieces 151 and 152 are overlapped with the screw holes 31b of the mounting bracket 31 via the T-shaped holes 14d of the main plate 14b of the vertical crosspiece 14, and the bolts 32 are attached to the crosspiece 151. , 152 are screwed into the screw holes 31b of the mounting bracket 31 via the long holes 15g of the flanges 15c and the T-shaped holes 14d of the main plate 14b of the vertical rail 14 and temporarily fixed.

この仮止めの状態では、各ボルト32を桟部材151、152の各鍔15cの長形孔15gに沿って移動させることができることから、桟部材151、152を各長形孔15gに沿って(図1のX方向に)移動させて、X方向の位置を調節する。   In this temporarily fixed state, the bolts 32 can be moved along the long holes 15g of the flanges 15c of the crosspieces 151 and 152. Therefore, the crosspieces 151 and 152 are moved along the long holes 15g ( (In the X direction in FIG. 1) to adjust the position in the X direction.

また、取付け金具31を縦桟14の主板14bの各T字形孔14dに沿って(縦桟14の長手方向に)移動させることができ、この取付け金具31と共に桟部材151、152も移動させることができる。この縦桟14の長手方向への桟部材151、152の移動により、縦桟14上に配置された3本の横桟15の間隔を調節する。   Further, the mounting bracket 31 can be moved along each T-shaped hole 14d of the main plate 14b of the vertical beam 14 (in the longitudinal direction of the vertical beam 14), and the beam members 151 and 152 are also moved together with the mounting bracket 31. Can do. The distance between the three horizontal rails 15 arranged on the vertical rail 14 is adjusted by the movement of the rail members 151 and 152 in the longitudinal direction of the vertical rail 14.

こうして3本の横桟15のX方向の位置を調節し、各横桟15の間隔を調節した後、それぞれの取付け金具31の各ボルト32を締め込んで、各横桟15を縦桟14上に固定する。   Thus, after adjusting the position of the three horizontal rails 15 in the X direction and adjusting the interval between the horizontal rails 15, the bolts 32 of the respective mounting brackets 31 are tightened so that the horizontal rails 15 are placed on the vertical rails 14. Secure to.

このように横桟15のX方向の位置を調節することができる。また、先に述べたようにベース桟12をY方向に移動させて、Y方向の位置を調節することができるため、ベース桟12の位置調節により横桟15のY方向の位置を調節することができる。従って、横桟15のXY方向の位置調節が可能である。更に、各横桟15の間隔を調節することができる。このため、各コンクリート基礎11の位置に誤差があっても、各横桟15のXY方向の位置調節及び各横桟15の間隔の調節により各横桟15の位置決めを正確に行うことができ、延いては各横桟15上に取付けられる各太陽電池モジュール17の位置決めを正確に行うことができる。   In this way, the position of the horizontal rail 15 in the X direction can be adjusted. Further, as described above, the base beam 12 can be moved in the Y direction to adjust the position in the Y direction. Therefore, the position of the horizontal beam 15 can be adjusted by adjusting the position of the base beam 12. Can do. Accordingly, the position of the horizontal rail 15 in the XY direction can be adjusted. Further, the interval between the horizontal rails 15 can be adjusted. For this reason, even if there is an error in the position of each concrete foundation 11, each horizontal beam 15 can be accurately positioned by adjusting the position of each horizontal beam 15 in the XY direction and adjusting the interval between the horizontal beams 15, As a result, each solar cell module 17 mounted on each horizontal rail 15 can be accurately positioned.

次に、横桟15を構成する複数の桟部材151、152の接続構造について説明する。   Next, the connection structure of the some crosspiece members 151 and 152 which comprise the horizontal crosspiece 15 is demonstrated.

図7に示す桟部材151は、図1における横桟15の最も右側の1番目の桟部材であり、図1における1番目と2番目の各コンクリート基礎11の縦桟14間に架け渡され、これらの縦桟14に取付け金具31を用いて固定される。   The crosspiece member 151 shown in FIG. 7 is the first rightmost crosspiece member of the horizontal crosspiece 15 in FIG. 1, and is bridged between the vertical crosspieces 14 of the first and second concrete foundations 11 in FIG. It is fixed to these vertical bars 14 using mounting brackets 31.

また、図8に示す桟部材152は、図1における横桟15の2番目以降の桟部材であり、1つ手前の順番の桟部材の左側端部と次の縦桟14間に架け渡される。例えば、2番目の桟部材152が1番目の桟部材151の左側端部と3番目の縦桟14間に架け渡され、また3番目の桟部材152が2番目の桟部材152の左側端部と4番目の縦桟14間に架け渡され、以降同様に、n番目の桟部材152が(n−1)番目の桟部材152の左側端部と(n+1)番目の縦桟14間に架け渡される。そして、2番目以降の桟部材152も、それぞれの縦桟14に取付け金具31を用いて固定される。   A crosspiece member 152 shown in FIG. 8 is a second or subsequent crosspiece member of the horizontal crosspiece 15 in FIG. 1, and is bridged between the left end portion of the first crosspiece member and the next vertical crosspiece 14. . For example, the second cross member 152 is bridged between the left end portion of the first cross member 151 and the third vertical cross member 14, and the third cross member 152 is the left end portion of the second cross member 152. And the fourth vertical beam 14, and similarly, the nth beam member 152 extends between the left end of the (n−1) th beam member 152 and the (n + 1) th vertical beam 14. Passed. The second and subsequent crosspieces 152 are also fixed to the respective vertical crosspieces 14 using the mounting bracket 31.

図7(a)、(b)に示すように1番目の桟部材151の両端部のいずれにおいても主板15bが切除されていない。また、図8に示すように2番目以降の桟部材152の片側端部152-1で主板15b及び各側板15aの一辺に沿う部分が切除されて、各側板15a及び各鍔15cだけが残されている。そして、図1及び図3に示すように2番目以降の各桟部材152の片側端部152-1が1つ手前の順番の桟部材の左側端部に接続さている。   As shown in FIGS. 7A and 7B, the main plate 15b is not cut off at either end of the first crosspiece 151. Further, as shown in FIG. 8, a portion along one side of the main plate 15b and each side plate 15a is cut off at one end portion 152-1 of the second and subsequent crosspiece members 152, and only the side plates 15a and the flanges 15c are left. ing. As shown in FIGS. 1 and 3, one end 152-1 of each of the second and subsequent crosspiece members 152 is connected to the left end of the first crosspiece member.

例えば、図17(a)に示すように2番目の桟部材152の各側板15aの片側端部内側に1番目の桟部材151の各側板15aの左側端部を差し込んで挟み込んでいる。図10に示すように横桟15(桟部材151、152)のハット型断面形状の開口部側で各側板15aが広がっていることから、2番目の桟部材152の各側板15aの片側端部を1番目の桟部材151の各側板15aの左側端部に被せるようにするだけで、2番目の各側板15aの片側端部内側に1番目の各側板15aの左側端部を差し込んで挟み込むことができる。   For example, as shown in FIG. 17A, the left end of each side plate 15 a of the first cross member 151 is inserted and sandwiched inside one end of each side plate 15 a of the second cross member 152. As shown in FIG. 10, each side plate 15a spreads out on the side of the hat-shaped cross-sectional opening of the horizontal beam 15 (the beam members 151 and 152), so one side end portion of each side plate 15a of the second beam member 152 Is simply put on the left end of each side plate 15a of the first crosspiece 151, and the left end of each first side plate 15a is inserted and sandwiched inside one end of each second side plate 15a. Can do.

この状態で、図17(b)に示すように1番目の桟部材151の各側板15a間にパイプ25を挿入して、パイプ25、1番目の桟部材151の各側板15aのボルト孔15f、及び2番目の桟部材152の各側板15aのボルト孔15fを位置合わせし、ボルト26をパイプ25、1番目の桟部材151の各側板15aのボルト孔15f、2番目の桟部材152の各側板15aのボルト孔15f、及びワッシャに通して、ボルト26の一端にナット27をねじ込んで締め込み、2番目の桟部材152の各側板15aを1番目の桟部材151の各側板15aに接続する。   In this state, as shown in FIG. 17 (b), the pipe 25 is inserted between the side plates 15a of the first crosspiece member 151, the pipe 25, the bolt holes 15f of the side plates 15a of the first crosspiece member 151, The bolt holes 15f of the side plates 15a of the second cross member 152 are aligned, the bolts 26 are connected to the pipe 25, the bolt holes 15f of the side plates 15a of the first cross member 151, and the side plates of the second cross member 152. The nut 27 is screwed into one end of the bolt 26 and tightened through the bolt hole 15f and the washer 15a, and the side plates 15a of the second cross member 152 are connected to the side plates 15a of the first cross member 151.

また、3番目の桟部材152の各側板15aの片側端部を2番目の桟部材151の各側板15aの左側端部に被せて、3番目の各側板15aの片側端部内側に2番目の各側板15aの左側端部を差し込んで挟み込み、パイプ25、ボルト26、ナット27、及びワッシャを用いて、3番目の各側板15aを2番目の各側板15aに接続する。   In addition, one side end portion of each side plate 15a of the third cross member 152 is put on the left end portion of each side plate 15a of the second cross member 151, and the second end is placed inside the one end portion of each third side plate 15a. The left end of each side plate 15a is inserted and sandwiched, and the third side plate 15a is connected to the second side plate 15a by using a pipe 25, a bolt 26, a nut 27, and a washer.

同様に、n番目の桟部材152の各側板15aの片側端部内側に(n−1)番目の桟部材151の各側板15aの左側端部を差し込んで挟み込み、パイプ25、ボルト26、ナット27、及びワッシャを用いて、n番目の各側板15aを(n−1)番目の各側板15aに接続する。   Similarly, the left end of each side plate 15a of the (n-1) th cross member 151 is inserted and sandwiched inside one end of each side plate 15a of the nth cross member 152, and the pipe 25, bolt 26, nut 27 is inserted. The nth side plate 15a is connected to the (n-1) th side plate 15a by using a washer.

このように複数の桟部材151、152を接続することにより1本の長い横桟15を構成している。   In this way, one long horizontal beam 15 is configured by connecting a plurality of beam members 151 and 152.

図17(a)、(b)から明らかなように各桟部材151、152の接続箇所では、両側の側板15aが2重構造となり、その強度が向上する。しかも、横桟15を延長するべく、桟部材151、152の本数を増やしても、同様の接続工程を繰り返すだけであるから、施工作業が容易である。   As is apparent from FIGS. 17A and 17B, the side plates 15a on both sides have a double structure at the connection location of the crosspiece members 151 and 152, and the strength thereof is improved. Moreover, even if the number of the crosspiece members 151 and 152 is increased in order to extend the horizontal crosspiece 15, the construction process is easy because only the same connection process is repeated.

また、桟部材152の片側端部152-1で主板15bを切除していることから、各桟部材の接続箇所において該各桟部材の主板15bが離間する。このため、各桟部材の主板15bが相互に干渉することはなく、各桟部材の端部の接続が容易になる。   In addition, since the main plate 15b is cut off at the one end portion 152-1 of the crosspiece member 152, the main plate 15b of each crosspiece member is separated at the connection portion of each crosspiece member. For this reason, the main plates 15b of the cross members do not interfere with each other, and the end portions of the cross members are easily connected.

次に、中央の横桟15を補強するためのトラス構造について説明する。   Next, a truss structure for reinforcing the central cross rail 15 will be described.

ここで、図1に示すように3本の横桟15上に複数の太陽電池モジュール17が2列に並べて搭載されていることから、中央の横桟15には、上側及び下側の横桟15よりも大きな荷重がかかっている。例えば、図1において最も右側にある上下2枚の太陽電池モジュール17に着眼すると、上側及び下側の横桟15には0.5枚分の太陽電池モジュール17の荷重がそれぞれかかり、中央の横桟15には1.0枚分の太陽電池モジュール17の荷重がかかると概ね考えることができる。従って、中央の横桟15には、上側及び下側の横桟15と比較して、略2倍の荷重がかかる。   Here, as shown in FIG. 1, a plurality of solar cell modules 17 are mounted in two rows on the three horizontal rails 15, so that the central horizontal rail 15 has upper and lower horizontal rails. A load greater than 15 is applied. For example, when attention is paid to the upper and lower two solar cell modules 17 on the rightmost side in FIG. 1, the load of 0.5 solar cell modules 17 is applied to the upper and lower horizontal rails 15 respectively. It can be generally considered that a load of 1.0 solar cell modules 17 is applied to the crosspiece 15. Therefore, a load approximately twice as large as that of the upper and lower horizontal rails 15 is applied to the central horizontal rail 15.

そこで、上側及び下側の横桟15にかかる小さな荷重に合わせて、3本の横桟15の強度を設定して、各横桟15を共通化すれば、各横桟15の軽量化とコストの低減を果たすことができる。ただし、中央の横桟15の強度が不足するので、図1に示すようにベース桟12と中央の横桟15間に2本のトラス16を架け渡して、中央の横桟15を補強するためのトラス構造を構築している。   Therefore, if the strength of the three horizontal rails 15 is set according to the small load applied to the upper and lower horizontal rails 15 and each horizontal rail 15 is made common, the weight and cost of each horizontal rail 15 are reduced. Can be reduced. However, since the strength of the central crosspiece 15 is insufficient, two truss 16 are bridged between the base crosspiece 12 and the central crosspiece 15 to reinforce the central crosspiece 15 as shown in FIG. The truss structure is built.

換言すれば、各横桟15のうちの中央のものだけを補強するという構造により、上側及び下側の横桟15にかかる小さな荷重を基準にして、3本の横桟15の強度を設定し、各横桟15の軽量化とコストの低減を果たしている。   In other words, the strength of the three horizontal rails 15 is set based on the small load applied to the upper and lower horizontal rails 15 by the structure in which only the middle one of the horizontal rails 15 is reinforced. The weight of each crosspiece 15 is reduced and the cost is reduced.

尚、本実施形態では、太陽電池モジュール17を2列に並べたが、3列以上並べてもよい。その場合、上端の横桟および下端の横桟以外の横桟は、上記の中央の横桟に相当するものとし、トラスを付設する。   In addition, in this embodiment, although the solar cell module 17 was arranged in 2 rows, you may arrange 3 or more rows. In this case, the horizontal rails other than the upper horizontal rail and the lower horizontal rail correspond to the central horizontal rail, and a truss is attached.

また、図1において最も右側のベース桟12を1番目とすると、偶数番目のベース桟12毎に、トラス構造を配している。これにより、中央の横桟15のそれぞれの桟部材151、152が1本のトラス16のみにより補強され、トラス16の本数が抑えられて、施工作業の煩雑化及びコストの上昇が抑えられる。   Further, assuming that the rightmost base beam 12 is the first in FIG. 1, a truss structure is provided for each even-numbered base beam 12. As a result, the crosspiece members 151 and 152 of the central crosspiece 15 are reinforced by only one truss 16, and the number of trusses 16 is reduced, thereby preventing the construction work from being complicated and the cost from increasing.

図18及び図19は、ベース桟12と中央の横桟15間に架け渡された各トラス16を示す正面図及び側面図である。図19から明らかなように各トラス16を側方から見ると、各トラス16を太陽電池モジュール17に対して垂直に配置している。これは、太陽電池モジュール17の荷重もしくは風圧によりトラス16が倒されないようにするためである。また、各トラス16を太陽電池モジュール17に対して垂直に配置するには、各トラス16をベース桟12に対して斜めに支持する必要があり、このためにベース桟12と2本のトラス16を接続するための接続金具31の各側板31bを傾斜させている。   FIGS. 18 and 19 are a front view and a side view showing the trusses 16 spanned between the base rail 12 and the central horizontal rail 15. As apparent from FIG. 19, when the trusses 16 are viewed from the side, the trusses 16 are arranged perpendicular to the solar cell module 17. This is to prevent the truss 16 from being overturned by the load or wind pressure of the solar cell module 17. Further, in order to arrange each truss 16 perpendicular to the solar cell module 17, it is necessary to support each truss 16 obliquely with respect to the base beam 12. For this reason, the base beam 12 and the two trusses 16 are required. Each side plate 31b of the connection fitting 31 for connecting is inclined.

図20(a)、(b)は、ベース桟12と2本のトラス16を接続するための接続金具31を示す斜視図及び側面図である。この接続金具31は、主板31aと、主板31aの両縁で折り曲げられたそれぞれの側板31bとを有しており、主板31aに対して各側板31bが斜めに傾斜している。主板31aには2本の長形孔31cが形成され、各側板31bにはボルト孔31d及びネジ孔31eがそれぞれ形成されている。   FIGS. 20A and 20B are a perspective view and a side view showing a connection fitting 31 for connecting the base bar 12 and the two trusses 16, respectively. The connection fitting 31 has a main plate 31a and side plates 31b bent at both edges of the main plate 31a, and each side plate 31b is inclined with respect to the main plate 31a. Two long holes 31c are formed in the main plate 31a, and bolt holes 31d and screw holes 31e are formed in each side plate 31b.

この接続金具31の主板31aを偶数番目のベース桟12の各鍔12cの略中央に載せ、主板31aの2つの長形孔31cを各鍔12cのボルト孔12fに重ねて、2本のボルトを主板31aの各長形孔31cと各鍔12cのボルト孔12fに通して、これらのボルトの一端にそれぞれのナットをねじ込み、接続金具31をベース桟12の各鍔12c上に仮止めする。   The main plate 31a of the connection fitting 31 is placed in the approximate center of each rod 12c of the even-numbered base bar 12, and the two long holes 31c of the main plate 31a are overlapped with the bolt holes 12f of each rod 12c, and two bolts are attached. The nuts are screwed into one end of these bolts through the elongated holes 31c of the main plate 31a and the bolt holes 12f of the flanges 12c, and the connection fittings 31 are temporarily fixed on the flanges 12c of the base bar 12.

この仮止め状態では、各ボルトを接続金具31の主板31aの各長形孔31cに通していることから、接続金具31を各長形孔31cに沿って(図1のX方向に)移動させることができる。   In this temporarily fixed state, since each bolt is passed through each long hole 31c of the main plate 31a of the connection fitting 31, the connection fitting 31 is moved along each long hole 31c (in the X direction in FIG. 1). be able to.

この接続金具31の仮止めの後、2本のトラス16の両端部を接続金具31と中央の横桟15に接続する。このとき、2本のトラス16の各側板16aの端部(図9における一端部16-1)と接続金具31の各側板31bが互い違いになるように重ね合わせる。そして、相互に対向する最も内側の各側板間にパイプを挿入して、パイプ、各トラス16の各側板16aのボルト孔16d、及び接続金具31の各側板31bの孔31d、31eを位置合わせし、ボルトをパイプ、2本のトラス16の各側板16aのボルト孔16d、接続金具31の側板31bのボルト孔31d、及びワッシャに通して、ボルトの一端を接続金具31の側板31bのネジ孔31eにねじ込んで、2本のトラス16の端部を接続金具31に仮止めする。   After temporarily fixing the connection fitting 31, both ends of the two trusses 16 are connected to the connection fitting 31 and the central crosspiece 15. At this time, the end portions (one end portion 16-1 in FIG. 9) of the side plates 16a of the two trusses 16 and the side plates 31b of the connection fitting 31 are overlapped with each other. Then, pipes are inserted between the innermost side plates facing each other, and the pipes, the bolt holes 16d of the side plates 16a of the trusses 16 and the holes 31d and 31e of the side plates 31b of the connection fitting 31 are aligned. The bolt is passed through the pipe, the bolt hole 16d of each side plate 16a of the two trusses 16, the bolt hole 31d of the side plate 31b of the connection fitting 31, and the washer, and one end of the bolt is threaded 31e of the side plate 31b of the connection fitting 31. Then, the ends of the two trusses 16 are temporarily fixed to the connection fitting 31.

また、2本のトラス16のいずれについても、トラス16の各側板16aの端部(図9における他端部16-2)を相互に接近するように弾性変形させつつ、これらの側板16aの端部を中央の横桟15の桟部材151又は152の各側板15aの内側に差し込む。そして、トラス16の各側板16a間にパイプを挿入して、パイプ、トラス16の各側板16aのボルト孔16d、及び桟部材151又は152の各側板15aのボルト孔15fを位置合わせし、ボルトをパイプ、トラス16の各側板16aのボルト孔16d、桟部材151又は152の各側板15aのボルト孔15f、及びワッシャに通して、ボルトの一端にナットをねじ込んで、各トラス16の端部を桟部材151又は152に仮止めする。   Further, for both of the two trusses 16, the end portions of the side plates 16a of the truss 16 are elastically deformed so that the end portions (the other end portion 16-2 in FIG. 9) approach each other. The portion is inserted inside the side plate 15a of the crosspiece member 151 or 152 of the central horizontal crosspiece 15. Then, pipes are inserted between the side plates 16a of the truss 16, the bolt holes 16d of the side plates 16a of the truss 16 and the bolt holes 15f of the side plates 15a of the crosspieces 151 or 152 are aligned, and the bolts are Pipe, bolt hole 16d of each side plate 16a of truss 16, bolt hole 15f of each side plate 15a of crosspiece 151 or 152, and washer are screwed into one end of the bolt, and the end of each truss 16 is crosspieced. Temporarily fix to the member 151 or 152.

このような各トラス16の取付けに際しては、接続金具31を各長形孔31cに沿って(図1のX方向に)移動させながら、各トラス16の各側板16aの端部(図9における他端部16-2)の位置を調節して、各側板16aの端部のボルト孔16dと桟部材151又は152の各側板15aのボルト孔15fの位置合わせを行う必要がある。これは、先に述べたように横桟15の桟部材151、152をX方向に移動させて、横桟15のX方向の位置を調節していることから、この横桟15のX方向の位置の調節分だけ各トラス16の位置もずらす必要があるためである。   When attaching each truss 16 as described above, the end of each side plate 16a of each truss 16 (the other in FIG. 9) is moved while the connection fitting 31 is moved along each elongated hole 31c (in the X direction in FIG. 1). It is necessary to adjust the position of the end portion 16-2) to align the bolt hole 16d at the end portion of each side plate 16a with the bolt hole 15f of each side plate 15a of the crosspiece member 151 or 152. As described above, the crosspieces 151 and 152 of the crosspiece 15 are moved in the X direction to adjust the position of the crosspiece 15 in the X direction. This is because it is necessary to shift the position of each truss 16 by the position adjustment.

こうして各トラス16の両端部を接続金具31と中央の横桟15に接続した後、各トラス16の両端部を接続するためのそれぞれのボルトを締め込んで、各トラス16を固定する。   After connecting both ends of each truss 16 to the connection fitting 31 and the central crosspiece 15, each bolt for connecting both ends of each truss 16 is tightened to fix each truss 16.

次に、太陽電池モジュール17を横桟15上に取付けるための構造について説明する。   Next, a structure for mounting the solar cell module 17 on the horizontal rail 15 will be described.

ここで、図1から明らかなように中央の横桟15は、上下の太陽電池モジュール17の端部を支持し、また上側及び下側の横桟15は、上側又は下側の太陽電池モジュール17の端部を支持している。このため、太陽電池モジュール17の取付け構造は、中央の横桟15と上側及び下側の横桟15とでは異なり、これらの取付け構造を別々に説明する。   Here, as is clear from FIG. 1, the central horizontal beam 15 supports the ends of the upper and lower solar cell modules 17, and the upper and lower horizontal beams 15 are the upper or lower solar cell module 17. The end of the is supported. For this reason, the mounting structure of the solar cell module 17 is different between the central horizontal rail 15 and the upper and lower horizontal rails 15, and these mounting structures will be described separately.

図21(a)、(b)、(c)は、中央の横桟15において太陽電池モジュール17の裏面側に配置される第1接続金具を示す正面図、及び第1接続金具を表裏から見て示すそれぞれの斜視図ある。この第1接続金具41は、側板41a、及び側板41aの上縁で折り曲げられた主板41bを有している。主板41bには、該主板41bの一辺中央部で折れ曲がって垂下する垂下片41e、及び該主板41bの一辺両端部で折れ曲がって起こされた各突起部41fが形成されている。また、主板41bの略中央にネジ孔41dが形成され、側板41aにボルト孔41cが形成されている。側板41aの高さは、横桟15の側板15aの高さに略等しい。   FIGS. 21A, 21B, and 21C are a front view showing the first connection fitting disposed on the back side of the solar cell module 17 in the central cross rail 15, and the first connection fitting seen from the front and back. FIG. The first connection fitting 41 has a side plate 41a and a main plate 41b bent at the upper edge of the side plate 41a. The main plate 41b is formed with a hanging piece 41e that is bent at the central portion of one side of the main plate 41b and a protruding portion 41f that is bent and raised at both ends of the one side of the main plate 41b. Further, a screw hole 41d is formed in the approximate center of the main plate 41b, and a bolt hole 41c is formed in the side plate 41a. The height of the side plate 41a is substantially equal to the height of the side plate 15a of the horizontal rail 15.

図22(a)、(b)は、図21の第1接続金具41と共に用いられる補強金具を示す斜視図及び平面図である。この補強金具42は、相互に対向する一対の側板42a、各側板42aの対向一辺を連結する主板42b、及び各側板42aの縁で折れ曲がって外側に突出するそれぞれの鍔42cからなるハット型断面形状を有しており、横桟15の内側に嵌合されるような幅に設定されている。   22A and 22B are a perspective view and a plan view showing a reinforcing metal fitting used together with the first connecting metal fitting 41 of FIG. The reinforcing metal fitting 42 has a hat-shaped cross-sectional shape including a pair of side plates 42a facing each other, a main plate 42b connecting one side of each side plate 42a, and a flange 42c that is bent at the edge of each side plate 42a and protrudes outward. The width is set so as to be fitted inside the horizontal rail 15.

この補強金具42の各側板42aにはそれぞれのネジ孔42dが形成され、また各鍔42cにはそれぞれの長形孔42eが形成されている。   Each side plate 42a of the reinforcing metal fitting 42 is formed with a screw hole 42d, and each flange 42c is formed with a long hole 42e.

図23は、太陽電池モジュール17の受光面側に配置される第1固定金具を示す斜視図である。この第1固定金具43は、押圧板43aの前後端部に下方に折り曲げられた突起片43bを形成し、押圧板43aの中央部にボルト孔43cを形成したものである。   FIG. 23 is a perspective view showing the first fixing fitting disposed on the light receiving surface side of the solar cell module 17. The first fixing fitting 43 is formed by forming a protruding piece 43b bent downward at the front and rear end portions of the pressing plate 43a and forming a bolt hole 43c at the central portion of the pressing plate 43a.

図24は、太陽電池モジュール17の受光面側に配置される第2固定金具を示す斜視図である。この第2固定金具44は、押圧板44aの前後端部に下方に折り曲げられた突起片44bを形成し、押圧板44aの中央部にボルト孔44cを形成し、押圧板44aの一端縁から垂直に屈曲した立壁44dを形成し、立壁44dの下端縁を折り曲げて底部片44eを形成したものである。   FIG. 24 is a perspective view showing the second fixing bracket disposed on the light receiving surface side of the solar cell module 17. The second fixing bracket 44 has a protruding piece 44b bent downward at the front and rear end portions of the pressing plate 44a, a bolt hole 44c formed at the central portion of the pressing plate 44a, and perpendicular to one end edge of the pressing plate 44a. A standing wall 44d is formed, and the bottom edge 44e is formed by bending the lower edge of the standing wall 44d.

第1接続金具41、補強金具42、第1及び第2固定金具43、44のいずれも、ベース桟12、アーム13、縦桟14、横桟15、及びトラス16よりも十分に厚い鋼板を加工したものであり、高い強度を有する。   All of the first connection fitting 41, the reinforcing fitting 42, and the first and second fixing fittings 43 and 44 are made of steel plates that are sufficiently thicker than the base rail 12, the arm 13, the vertical rail 14, the horizontal rail 15, and the truss 16. It has a high strength.

ここで、第1接続金具41は、中央の横桟15の桟部材151、152の主板15bにおける一対のスリット15dとボルト孔15eの形成箇所にそれぞれ2個1組で配され、図25に示すように2個の第1接続金具41の側板41aが横桟15の各側板15aに重ねられ、これらの第1接続金具41の主板41bが横桟15から外向きに突出するように向けられ、これらの第1接続金具41の各突起部41fが横桟15の主板15bよりも上方に突出する。   Here, two first connection fittings 41 are arranged in pairs at the positions where the pair of slits 15d and bolt holes 15e are formed in the main plate 15b of the crosspieces 151 and 152 of the central crosspiece 15 as shown in FIG. As described above, the side plates 41a of the two first connection fittings 41 are stacked on the side plates 15a of the horizontal rails 15, and the main plates 41b of these first connection fittings 41 are directed so as to protrude outward from the horizontal rails 15, Each protrusion 41f of the first connection fitting 41 protrudes upward from the main plate 15b of the cross rail 15.

また、補強金具42も、第1接続金具41と同様に、中央の横桟15の主板15bにおける一対のスリット15dとボルト孔15eの形成箇所に配されて、横桟15の内側に嵌合され、図25に示すように補助金具42の各側板42aが横桟15の各側板15aの下側部分に重ねられ、補助金具42の各鍔42cが横桟15の各鍔15cに重ねられる。   Similarly to the first connection fitting 41, the reinforcing fitting 42 is also arranged at a position where the pair of slits 15 d and the bolt hole 15 e are formed in the main plate 15 b of the central transverse rail 15 and is fitted inside the lateral rail 15. As shown in FIG. 25, each side plate 42a of the auxiliary metal fitting 42 is overlaid on the lower part of each side plate 15a of the horizontal rail 15, and each bar 42c of the auxiliary metal fitting 42 is overlapped with each bar 15c of the horizontal rail 15.

そして、図25に示すように2本のボルトが、第1接続金具41の各側板41aのボルト孔41c及び横桟15の各側板15aのボルト孔15fを介して補助金具42の各側板42aのネジ孔42dにそれぞれねじ込まれて締めこまれる。このため、第1接続金具41の部位では、側板及び鍔が2重もしくは3重構造となり、この部位での強度が高くなる。   Then, as shown in FIG. 25, two bolts are connected to each side plate 42a of the auxiliary fitting 42 through the bolt holes 41c of each side plate 41a of the first connection fitting 41 and the bolt holes 15f of each side plate 15a of the horizontal rail 15. Each screw hole 42d is screwed and tightened. For this reason, in the site | part of the 1st connection metal fitting 41, a side plate and a collar become a double or triple structure, and the intensity | strength in this site | part becomes high.

尚、図1における中央の横桟15の最も右側の1番目の桟部材151には、図7に示すように一対のスリット15dとボルト孔15eが4箇所に形成されていることから、この4箇所に第1接続金具41が2個ずつ設けられ、同4箇所に補助金具42が1個ずつ設けられる。また、横桟15の2番目以降の桟部材151には、図8に示すように一対のスリット15dとボルト孔15eが3箇所に形成されていることから、この3箇所に第1接続金具41が2個ずつ設けられ、同3箇所に補助金具42が1個ずつ設けられる。   Incidentally, since the first crosspiece 151 on the rightmost side of the central crosspiece 15 in FIG. 1 has a pair of slits 15d and bolt holes 15e formed in four places as shown in FIG. Two first connection fittings 41 are provided at each location, and one auxiliary fitting 42 is provided at each of the four locations. Further, as shown in FIG. 8, a pair of slits 15d and bolt holes 15e are formed in three places in the second and subsequent crosspiece members 151 of the horizontal crosspiece 15. Therefore, the first connection fitting 41 is provided in these three places. Are provided two by two, and one auxiliary metal fitting 42 is provided at each of the three locations.

また、図7に示す桟部材151の両端部においては、補助金具42の各鍔42cの長形孔42eが桟部材151の各鍔15cの長形孔15gに重なる。更に、図8に示す桟部材152の片端部においても、補助金具42の各鍔42cの長形孔42eが桟部材152の各鍔15cの長形孔15gに重なる。このため、桟部材151、152の各鍔15cの長形孔15gが補助金具42の各鍔42cで塞がれたり、それらの長形孔15gの長さが制限されることはなく、各長形孔15gに沿う(図1のX方向)桟部材151、152の移動が阻まれることはない。   In addition, at both ends of the crosspiece member 151 shown in FIG. 7, the elongated holes 42e of the flanges 42c of the auxiliary metal fitting 42 overlap the elongated holes 15g of the flanges 15c of the crosspiece member 151. Further, also at one end portion of the crosspiece member 152 shown in FIG. 8, the long holes 42 e of the respective flanges 42 c of the auxiliary metal fitting 42 overlap the long holes 15 g of the respective flanges 15 c of the crosspiece member 152. Therefore, the elongated holes 15g of the flanges 15c of the crosspieces 151 and 152 are not blocked by the flanges 42c of the auxiliary metal fitting 42, and the lengths of the elongated holes 15g are not limited. The movement of the crosspiece members 151 and 152 along the shape hole 15g (X direction in FIG. 1) is not hindered.

図26(a)は、第1接続金具41、補強金具42、及び第1固定金具43を用いて、中央の横桟15に上下左右4枚の太陽電池モジュール17を取付けた状態を示す平面図である。また、図26(b)は図26(a)のB−Bに沿う断面図であり、図25(c)C−Cに沿う断面図である。更に、図27は、図26の状態を太陽電池モジュールの受光面側から見て示す斜視図である。   FIG. 26A is a plan view showing a state in which four solar cell modules 17 are attached to the central cross rail 15 using the first connection fitting 41, the reinforcement fitting 42, and the first fixing fitting 43. It is. Moreover, FIG.26 (b) is sectional drawing which follows BB of Fig.26 (a), and is sectional drawing which follows FIG.25 (c) CC. Further, FIG. 27 is a perspective view showing the state of FIG. 26 as viewed from the light receiving surface side of the solar cell module.

図26(a)、(b)、(c)に示すように下側左右の各太陽電池モジュール17の枠部材19を下側の第1接続金具41の各突起部41f間に入れて横桟15の主板15b上に載置する。このとき、下側左右の各太陽電池モジュール17の枠部材19の内縁19aが下側の第1接続金具41の各突起部41fに当接するまで、各太陽電池モジュール17が横桟15の主板15b上でずれ落ちて、各太陽電池モジュール17の上下位置が位置決めされる。   26 (a), (b), and (c), the frame member 19 of each of the lower left and right solar cell modules 17 is inserted between the protrusions 41f of the lower first connection fitting 41, and the horizontal rails are inserted. It is placed on 15 main plates 15b. At this time, each solar cell module 17 is connected to the main plate 15b of the horizontal rail 15 until the inner edge 19a of the frame member 19 of each of the lower left and right solar cell modules 17 comes into contact with each protrusion 41f of the lower first connection fitting 41. The upper and lower positions of each solar cell module 17 are positioned by shifting upward.

そして、図26(a)、(b)、図27に示すように下側左右の各太陽電池モジュール17の枠部材19間に第1固定金具43の各突起片43bを差し込んで、該各太陽電池モジュール17の枠部材19を一定間隔だけ離間させ、同時に図26(b)に示すように該各太陽電池モジュール17の枠部材19の底辺突起部19bを第1接続金具41の各突起部41fに当接させて、該各太陽電池モジュール17の左右位置を位置決めする。   Then, as shown in FIGS. 26 (a), (b), and FIG. 27, the projection pieces 43 b of the first fixing bracket 43 are inserted between the frame members 19 of the lower left and right solar cell modules 17 to The frame members 19 of the battery modules 17 are spaced apart by a fixed interval, and at the same time, the bottom projections 19b of the frame members 19 of the solar cell modules 17 are connected to the projections 41f of the first connection fitting 41 as shown in FIG. The left and right positions of the solar cell modules 17 are positioned.

引き続いて、ボルト45を第1固定金具43のボルト孔43c及び下側左右の各太陽電池モジュール17の枠部材19の隙間を介して第1接続金具41の主板41のネジ孔41dにねじ込んで締め込む。これにより、第1固定金具43と横桟15の主板15b間に下側左右の各太陽電池モジュール17の枠部材19が挟み込まれて固定される。   Subsequently, the bolt 45 is screwed into the screw hole 41d of the main plate 41 of the first connection fitting 41 via the gap between the bolt hole 43c of the first fixing fitting 43 and the frame member 19 of each of the lower left and right solar cell modules 17 and tightened. Include. As a result, the frame members 19 of the lower left and right solar cell modules 17 are sandwiched and fixed between the first fixture 43 and the main plate 15b of the horizontal rail 15.

同様に、上側左右の各太陽電池モジュール17の枠部材19を上側の第1接続金具41の各突起部41f間に入れて横桟15の主板15b上に載置する。このとき、上側左右の各太陽電池モジュール17の枠部材19を下側左右の各太陽電池モジュール17の枠部材19に当接させて、上側左右の各太陽電池モジュール17の上下位置を位置決めする。そして、上側左右の各太陽電池モジュール17の枠部材19間に第1固定金具43の各突起片43bを差し込み、該各太陽電池モジュール17の枠部材19の底辺突起部19bを第1接続金具41の各突起部41fに当接させて、該各太陽電池モジュール17の左右位置を位置決めする。   Similarly, the frame members 19 of the upper left and right solar cell modules 17 are placed between the protrusions 41 f of the upper first connection fitting 41 and placed on the main plate 15 b of the horizontal rail 15. At this time, the frame members 19 of the upper left and right solar cell modules 17 are brought into contact with the frame members 19 of the lower left and right solar cell modules 17 to position the vertical positions of the upper left and right solar cell modules 17. And each protrusion piece 43b of the 1st fixing bracket 43 is inserted between the frame members 19 of each of the upper left and right solar cell modules 17, and the bottom protrusion 19b of the frame member 19 of each solar cell module 17 is connected to the first connection bracket 41. The left and right positions of the solar cell modules 17 are positioned in contact with the projections 41f.

引き続いて、ボルト45を第1固定金具43のボルト孔43c及び上側左右の各太陽電池モジュール17の枠部材19の隙間を介して第1接続金具41の主板41のネジ孔41dにねじ込んで締め込み、上側左右の各太陽電池モジュール17の枠部材19を固定する。   Subsequently, the bolt 45 is screwed into the screw hole 41d of the main plate 41 of the first connection fitting 41 through the gap between the bolt hole 43c of the first fixing fitting 43 and the frame member 19 of each of the upper left and right solar cell modules 17 and tightened. The frame members 19 of the upper left and right solar cell modules 17 are fixed.

一方、第2固定金具44は、図1において最も右側又は左側にある上下2枚の太陽電池モジュール17を固定するために用いられる。   On the other hand, the second fixing bracket 44 is used to fix the upper and lower two solar cell modules 17 located on the rightmost or left side in FIG.

図28に示すように最も右側又は左側の太陽電池モジュール17の枠部材19を第1接続金具41の各突起部41f間に入れて横桟15の主板15b上に載置する。そして、第2固定金具44の底部片44eを横桟15の主板15b上に載せ、第2固定金具44の各突起片44bを太陽電池モジュール17の枠部材19に押し付けて、太陽電池モジュール17の枠部材19の底辺突起部19bを第1接続金具41の突起部41fに当接させ、太陽電池モジュール17の左右位置を位置決めする。   As shown in FIG. 28, the frame member 19 of the rightmost or leftmost solar cell module 17 is placed between the protrusions 41 f of the first connection fitting 41 and placed on the main plate 15 b of the horizontal rail 15. Then, the bottom piece 44e of the second fixing bracket 44 is placed on the main plate 15b of the horizontal rail 15, and each protruding piece 44b of the second fixing bracket 44 is pressed against the frame member 19 of the solar cell module 17, so that the solar cell module 17 The bottom projection 19b of the frame member 19 is brought into contact with the projection 41f of the first connection fitting 41, and the left and right positions of the solar cell module 17 are positioned.

そして、ボルト45を第2固定金具44のボルト孔44cを介して第1接続金具41の主板41bのネジ孔41dにねじ込んで締め込む。これにより、第2固定金具44と横桟15の主板15b間に太陽電池モジュール17の枠部材19が挟み込まれて固定される。   Then, the bolt 45 is screwed into the screw hole 41 d of the main plate 41 b of the first connection fitting 41 through the bolt hole 44 c of the second fixing fitting 44 and tightened. As a result, the frame member 19 of the solar cell module 17 is sandwiched and fixed between the second fixing bracket 44 and the main plate 15 b of the horizontal rail 15.

ここで、先に述べたように第1接続金具41及び補助金具42の部位では、横桟15の側板15a、第1接続金具41の側板41a、及び補助金具42の側板42aが2重もしくは3重に重なり、また、横桟15の鍔15c及び補助金具42の鍔42cが2重に重なることから、この部位での強度が高くなる。また、横桟15の主板15b、各側板15a、及び補助金具42の主板42が四角状の閉構造となるので、これによっても該部位での強度が高くなる。   Here, as described above, in the portion of the first connection fitting 41 and the auxiliary fitting 42, the side plate 15a of the cross rail 15, the side plate 41a of the first connection fitting 41, and the side plate 42a of the auxiliary fitting 42 are double or three. In addition, since the flange 15c of the horizontal rail 15 and the flange 42c of the auxiliary bracket 42 are doubled, the strength at this portion is increased. Further, since the main plate 15b of the crosspiece 15 and the side plates 15a and the main plate 42 of the auxiliary metal fitting 42 have a square closed structure, this also increases the strength at the portion.

また、太陽電池モジュール17の表裏面に強い風圧がかかった際には、風圧により太陽電池モジュール17の中央部がたわみ、その影響で太陽電池モジュール17の枠部材19をその係止箇所から外そうとする強い力が発生する。ところが、本実施形態では、太陽電池モジュール17の表裏面に風圧がかかっても、第1接続金具41の突起部41fが太陽電池モジュール17の枠部材19の内側に引っ掛かり、太陽電池モジュール17の枠部材19が第1接続金具41と第1又は第2固定金具43、44間で挟み込まれることになるため、太陽電池モジュール17の枠部材19が外れることはない。   Further, when a strong wind pressure is applied to the front and back surfaces of the solar cell module 17, the central portion of the solar cell module 17 is bent by the wind pressure, and the frame member 19 of the solar cell module 17 is removed from the locking portion due to the influence. A strong force is generated. However, in the present embodiment, even if wind pressure is applied to the front and back surfaces of the solar cell module 17, the projection 41 f of the first connection fitting 41 is caught inside the frame member 19 of the solar cell module 17, and the frame of the solar cell module 17. Since the member 19 is sandwiched between the first connection fitting 41 and the first or second fixing fitting 43, 44, the frame member 19 of the solar cell module 17 is not detached.

更に、2個1組の第1接続金具41は、横桟15を介して対向配置され、横桟15の中心線S(図26(a)に示す)に対して上下対称に配置されている。そして、上下の各太陽電池モジュール17を固定するための各ボルト45がそれぞれの第1接続金具41のネジ孔41dにねじ込まれて、該各ボルト45も横桟15の中心線Sに対して上下対称に配置されている。   Further, the set of two first connection fittings 41 is disposed so as to face each other via the horizontal rail 15, and is arranged vertically symmetrically with respect to the center line S (shown in FIG. 26A) of the horizontal rail 15. . Then, the bolts 45 for fixing the upper and lower solar cell modules 17 are screwed into the screw holes 41 d of the first connection fittings 41, and the bolts 45 are also vertically moved with respect to the center line S of the horizontal rail 15. They are arranged symmetrically.

風圧の影響で第1接続金具41の突起部41fと第1又は第2固定金具43、44の箇所に力が生じるが、この配置設計を誤ると、この力が横桟15や太陽電池モジュール17の枠部材19をねじるように力が作用し、これらが変形してしまう。しかしながら、図26に示すように、2個1組の第1接続金具41の突起部41が第1又は第2固定金具43、44のボルト45並びに桟15の中心線Sと平行な直線上に概ね配置され、かつ、第1又は第2固定金具43、44のボルト45及び突起部41fが横桟15の中心線Sに対して上下対称に配置されているので、風圧の影響による力が横桟15や太陽電池モジュール17の枠部材19をねじるように作用することはなく、これらが変形することはない。   A force is generated at the position of the protrusion 41f of the first connection fitting 41 and the first or second fixing fitting 43, 44 due to the influence of the wind pressure. If this layout design is mistaken, this force is applied to the horizontal rail 15 or the solar cell module 17. A force acts so as to twist the frame member 19, and these are deformed. However, as shown in FIG. 26, the protrusions 41 of the pair of first connection fittings 41 are on a straight line parallel to the bolt 45 of the first or second fixing fitting 43, 44 and the center line S of the crosspiece 15. Since the bolts 45 and the projections 41f of the first or second fixing brackets 43 and 44 are arranged vertically symmetrically with respect to the center line S of the horizontal rail 15, the force due to the influence of wind pressure is lateral. It does not act to twist the crosspiece 15 or the frame member 19 of the solar cell module 17, and these do not deform.

このねじれの力を防ぐためには、2個の第1接続金具41の突起部41f及び第1又は第2固定金具43、44のボルト45を横桟15の中心線S上に配置することが最も望ましいが、図26から明らかなように上下の太陽電池モジュール17の枠部材19を横桟15の中心線S上に共に固定することができないため、2個の第1接続金具41の突起部41f及び第1又は第2固定金具43、44のボルト45を横桟15の中心線Sに対して対称な位置に設けている。   In order to prevent this twisting force, it is most preferable to arrange the protrusions 41f of the two first connection fittings 41 and the bolts 45 of the first or second fixing fittings 43 and 44 on the center line S of the horizontal rail 15. Although it is desirable, since the frame members 19 of the upper and lower solar cell modules 17 cannot be fixed together on the center line S of the horizontal rail 15 as is apparent from FIG. 26, the protruding portions 41 f of the two first connection fittings 41. The bolts 45 of the first or second fixing brackets 43 and 44 are provided at positions symmetrical with respect to the center line S of the horizontal rail 15.

また、各ボルト45を横桟15よりも十分に厚い第1接続金具41のネジ孔41dにねじ込んでいるので、太陽電池モジュール17にかかった風圧により各ボルト45が引き抜かれることもない。   Further, since each bolt 45 is screwed into the screw hole 41 d of the first connection fitting 41 that is sufficiently thicker than the horizontal rail 15, each bolt 45 is not pulled out by the wind pressure applied to the solar cell module 17.

すなわち、横桟15、第1接続金具41、及び補助金具42により2重もしくは3重構造と閉構造を構成し、かつ上下の各太陽電池モジュール17を固定するための各突起部41f及び各ボルト45を横桟15の中心線Sに対して上下対称に配し、かつ各ボルト45を十分に厚い第1接続金具41のネジ孔41dにねじ込んだことにより、横桟15の耐荷重性が大幅に向上している。   That is, each of the projections 41f and the bolts for forming a double or triple structure and a closed structure by the horizontal rail 15, the first connection fitting 41, and the auxiliary fitting 42, and for fixing the upper and lower solar cell modules 17 to each other. 45 is arranged symmetrically with respect to the center line S of the horizontal beam 15 and each bolt 45 is screwed into the screw hole 41d of the sufficiently thick first connection fitting 41, so that the load resistance of the horizontal beam 15 is greatly increased. Has improved.

図29Aは、上側及び下側の横桟15において太陽電池モジュール17の裏面側に配置される第2接続金具を示す斜視図である。また、図29B(a)、(b)は、図29Aの第2接続金具を示す平面図及び側面図である。この第2接続金具51は、相互に対向する一対の側板51a、各側板51aの対向一辺を連結する主板51b、及び各側板51aの縁で折れ曲がって外側に突出するそれぞれの鍔51cからなるハット型断面形状を有しており、横桟15の内側に嵌合するような形状及びサイズに設定されている。   FIG. 29A is a perspective view showing a second connection fitting disposed on the back side of the solar cell module 17 in the upper and lower horizontal rails 15. FIGS. 29B (a) and 29 (b) are a plan view and a side view showing the second connection fitting of FIG. 29A. The second connection fitting 51 is a hat-type comprising a pair of side plates 51a facing each other, a main plate 51b connecting the opposing sides of each side plate 51a, and a flange 51c that is bent at the edge of each side plate 51a and protrudes outward. It has a cross-sectional shape and is set to a shape and size that fits inside the horizontal rail 15.

この第2接続金具51の主板51bの両端から内側へとL字形の切り込みがそれぞれ形成され、これらのL字形の切り込みの内側が起こされて、それぞれの突起部51fとなっている。また、第2接続金具51の各側板51aにはそれぞれのネジ孔51dが形成され、主板51bの中心線上にネジ孔51eが形成され、各鍔51cにそれぞれの長形孔51gが形成されている。   L-shaped cuts are respectively formed from both ends of the main plate 51b of the second connection fitting 51 to the inside, and the insides of these L-shaped cuts are raised to form projections 51f. Further, each side plate 51a of the second connection fitting 51 is formed with a screw hole 51d, a screw hole 51e is formed on the center line of the main plate 51b, and each elongated hole 51g is formed in each flange 51c. .

この第2接続金具51も、第1接続金具41、補強金具42、第1及び第2固定金具43、44と同様に十分に厚い鋼板を加工したものであり、高い強度を有する。   The second connection fitting 51 is formed by processing a sufficiently thick steel plate similarly to the first connection fitting 41, the reinforcing fitting 42, and the first and second fixing fittings 43 and 44, and has high strength.

このような第2接続金具51は、上側及び下側の横桟15の主板15bにおける一対のスリット15dとボルト孔15eの形成箇所にそれぞれ配されて、横桟15の内側に嵌合される。   Such second connection fittings 51 are respectively arranged at positions where the pair of slits 15d and bolt holes 15e are formed in the main plate 15b of the upper and lower horizontal rails 15 and are fitted inside the horizontal rails 15.

図30に示すように第2接続金具51が横桟15の内側に嵌合されると、第2接続金具51の主板51bの各突起部51fが横桟15の主板15bの一対のスリット15dから上方に突出する。   As shown in FIG. 30, when the second connection fitting 51 is fitted inside the horizontal rail 15, the projections 51 f of the main plate 51 b of the second connection fitting 51 are formed from the pair of slits 15 d of the main plate 15 b of the horizontal rail 15. Projects upward.

また、第2接続金具51の各側板51aが横桟15の各側板15aに重なり、主板51bが横桟15の主板15bに重なり、各鍔51cが横桟15の各鍔15cに重なる。   Further, the side plates 51 a of the second connection fitting 51 overlap the side plates 15 a of the horizontal rail 15, the main plate 51 b overlaps the main plate 15 b of the horizontal rail 15, and the flanges 51 c overlap the flanges 15 c of the horizontal rail 15.

この状態で、2本のボルトが、横桟15の各側板15aのボルト孔15fを介して第2接続金具51の各側板51aのネジ孔51dにそれぞれねじ込まれて締め込まれる。このため、第2接続金具51の部位では、主板、側板、及び鍔が2重構造となり、この部位での強度が高くなる。   In this state, the two bolts are respectively screwed and tightened into the screw holes 51d of the side plates 51a of the second connection fitting 51 through the bolt holes 15f of the side plates 15a of the horizontal rail 15. For this reason, in the site | part of the 2nd connection metal fitting 51, a main board, a side board, and a collar become a double structure, and the intensity | strength in this site | part becomes high.

尚、図1における上側及び下側の横桟15の最も右側の1番目の桟部材151には、図7に示すように一対のスリット15dとボルト孔15eが4箇所に形成されていることから、この4箇所に第2接続金具51が設けられる。また、横桟15の2番目以降の桟部材151には、図8に示すように一対のスリット15dとボルト孔15eが3箇所に形成されていることから、この3箇所に第2接続金具51が設けられる。   Incidentally, since the rightmost first rail member 151 of the upper and lower horizontal rails 15 in FIG. 1 has a pair of slits 15d and bolt holes 15e formed in four places as shown in FIG. The second connection fittings 51 are provided at these four locations. Moreover, since the pair of slits 15d and the bolt holes 15e are formed in three places in the second and subsequent crosspiece members 151 of the horizontal crosspiece 15 as shown in FIG. 8, the second connection fitting 51 is provided in these three places. Is provided.

また、図7に示す桟部材151の両端部においては、第2接続金具51の各鍔51cの長形孔51gが桟部材151の各鍔15cの長形孔15gに重なる。更に、図8に示す桟部材152の片端部においても、第2接続金具51の各鍔51cの長形孔51gが桟部材152の各鍔15cの長形孔15gに重なる。このため、桟部材151、152の各鍔15cの長形孔15gが第2接続金具51各鍔51cで塞がれたり、それらの長形孔15gの長さが制限されることはなく、各長形孔15gに沿う桟部材151、152の移動が阻まれることはない。   In addition, at both ends of the crosspiece member 151 shown in FIG. 7, the long holes 51 g of the flanges 51 c of the second connection fitting 51 overlap the long holes 15 g of the hooks 15 c of the crosspiece member 151. Further, also at one end portion of the crosspiece member 152 shown in FIG. 8, the long holes 51 g of the flanges 51 c of the second connection fitting 51 overlap the long holes 15 g of the flanges 15 c of the crosspiece member 152. Therefore, the elongated holes 15g of the flanges 15c of the crosspieces 151, 152 are not blocked by the flanges 51c of the second connection fitting 51, and the length of the elongated holes 15g is not limited. The movement of the crosspiece members 151 and 152 along the long hole 15g is not obstructed.

図31(a)は、第2接続金具51及び第1固定金具43を用いて、上側及び下側の横桟15に左右の2枚の太陽電池モジュール17を取付けた状態を示す平面図である。また、図31(b)は図31(a)のB−Bに沿う断面図であり、図31(c)C−Cに沿う断面図である。   FIG. 31A is a plan view showing a state in which the left and right solar cell modules 17 are attached to the upper and lower horizontal rails 15 using the second connection fitting 51 and the first fixing fitting 43. . Moreover, FIG.31 (b) is sectional drawing which follows BB of Fig.31 (a), and is sectional drawing which follows CC of FIG.31 (c).

図31(a)、(b)、(c)に示すように左右の各太陽電池モジュール17の枠部材19を第2接続金具51の各突起部51f間に入れて横桟15の主板15b上に載置する。そして、左右の各太陽電池モジュール17の枠部材19間に第1固定金具43の各突起片43bを差し込んで、該各太陽電池モジュール17の枠部材19を一定間隔だけ離間させ、同時に該各太陽電池モジュール17の枠部材19の底辺突起部19bを第2接続金具51の各突起部51fに当接させて、該各太陽電池モジュール17の左右位置を位置決めする。   31 (a), 31 (b), and 31 (c), the frame member 19 of each of the left and right solar cell modules 17 is inserted between the projections 51f of the second connection fitting 51, and on the main plate 15b of the horizontal rail 15. Placed on. Then, the protruding pieces 43b of the first fixing bracket 43 are inserted between the frame members 19 of the left and right solar cell modules 17, and the frame members 19 of the solar cell modules 17 are separated by a predetermined interval. The bottom protrusion 19b of the frame member 19 of the battery module 17 is brought into contact with each protrusion 51f of the second connection fitting 51, and the left and right positions of the solar cell modules 17 are positioned.

引き続いて、ボルト45を第1固定金具43のボルト孔43c、各太陽電池モジュール17の枠部材19の隙間、及び横桟15の主板15bのボルト孔15eを介して第2接続金具51の主板51のネジ孔51eにねじ込んで締め込む。これにより、第1固定金具43と横桟15の主板15b間に各太陽電池モジュール17の枠部材19が挟み込まれて固定される。   Subsequently, the main plate 51 of the second connection fitting 51 is connected to the bolt 45 through the bolt hole 43c of the first fixing fitting 43, the gap between the frame members 19 of each solar cell module 17, and the bolt hole 15e of the main plate 15b of the horizontal rail 15. And screwed into the screw hole 51e. As a result, the frame member 19 of each solar cell module 17 is sandwiched and fixed between the first fixing fitting 43 and the main plate 15b of the horizontal rail 15.

一般には、施工性を考慮して、下側の太陽電池モジュール17の下側の側辺を支えるように接続金具を配置する。しかし、先に用いた第1接続金具41により中央の横桟15にて上下方向の位置決めがされているため、第2接続金具51による固定箇所は太陽電池モジュール17の水流れ方向の側辺でよい。このため施工性を損なうことなく、接続金具41、51の間隔を太陽電池モジュール17の水流れ方向の側辺より短くすることが可能となる。下側の太陽電池モジュール17に支えられて位置決めされる上側の太陽電池モジュール17の接続金具41、51の間隔についても同様である。これにより、縦桟14を上下の太陽電池モジュール17の水流れ方向の長さよりも短くすることが可能となり、延いては架台の小型化も可能になる。   In general, in consideration of workability, the connection fitting is arranged so as to support the lower side of the lower solar cell module 17. However, since the first connection fitting 41 used above is positioned in the vertical direction at the central crosspiece 15, the fixing location by the second connection fitting 51 is on the side of the solar cell module 17 in the water flow direction. Good. For this reason, it becomes possible to make the space | interval of the connection metal fittings 41 and 51 shorter than the side of the water flow direction of the solar cell module 17 without impairing workability. The same applies to the distance between the connection fittings 41 and 51 of the upper solar cell module 17 that is positioned by being supported by the lower solar cell module 17. As a result, it is possible to make the vertical rail 14 shorter than the length of the upper and lower solar cell modules 17 in the water flow direction, and it is possible to reduce the size of the gantry.

また、第2固定金具44は、図1において最も右側又は左側にある上下2枚の太陽電池モジュール17を固定するために用いられる。図32に示すように最も右側又は左側の太陽電池モジュール17の枠部材19を第2接続金具51の各突起部51f間に入れて横桟15の主板15b上に載置する。そして、第2固定金具44の底部片44eを横桟15の主板15b上に載せ、第2固定金具44の各突起片44bを太陽電池モジュール17の枠部材19に押し付けて、太陽電池モジュール17の枠部材19の底辺突起部19bを第2接続金具51の突起部51fに当接させ、太陽電池モジュール17の左右位置を位置決めし、ボルト45を第2固定金具44のボルト孔43c及び横桟15の主板15bのボルト孔15eを介して第2接続金具51の主板51のネジ孔51eにねじ込んで締め込む。これにより、第2固定金具44と横桟15の主板15b間に太陽電池モジュール17の枠部材19が挟み込まれて固定される。   Further, the second fixing bracket 44 is used for fixing the upper and lower two solar cell modules 17 located on the rightmost side or the left side in FIG. As shown in FIG. 32, the frame member 19 of the rightmost or leftmost solar cell module 17 is placed between the protrusions 51 f of the second connection fitting 51 and placed on the main plate 15 b of the horizontal rail 15. Then, the bottom piece 44e of the second fixing bracket 44 is placed on the main plate 15b of the horizontal rail 15, and each protruding piece 44b of the second fixing bracket 44 is pressed against the frame member 19 of the solar cell module 17, so that the solar cell module 17 The bottom protrusion 19b of the frame member 19 is brought into contact with the protrusion 51f of the second connection fitting 51, the left and right positions of the solar cell module 17 are positioned, and the bolt 45 is connected to the bolt hole 43c and the horizontal rail 15 of the second fixing fitting 44. And screwed into the screw hole 51e of the main plate 51 of the second connection fitting 51 through the bolt hole 15e of the main plate 15b. As a result, the frame member 19 of the solar cell module 17 is sandwiched and fixed between the second fixing bracket 44 and the main plate 15 b of the horizontal rail 15.

ここで、先に述べたように第2接続金具51の部位では、側板、主板、及び鍔が2重構造となることから、この部位での強度が高くなる。   Here, since the side plate, the main plate, and the flange have a double structure in the portion of the second connection fitting 51 as described above, the strength in this portion is increased.

また、太陽電池モジュール17の表裏面に強い風圧がかかった際には、風圧により太陽電池モジュール17の中央部がたわみ、その影響で太陽電池モジュール17の枠部材19をその係止箇所から外そうとする強い力が発生する。ところが、本実施形態では、太陽電池モジュール17の表裏面に風圧がかかっても、第2接続金具51の突起部51fが太陽電池モジュール17の枠部材19の内側に引っ掛かり、太陽電池モジュール17の枠部材19が第2接続金具51と第1又は第2固定金具43、44間で挟み込まれることになるため、太陽電池モジュール17の枠部材19が外れることはない。   Further, when a strong wind pressure is applied to the front and back surfaces of the solar cell module 17, the central portion of the solar cell module 17 is bent by the wind pressure, and the frame member 19 of the solar cell module 17 is removed from the locking portion due to the influence. A strong force is generated. However, in the present embodiment, even if wind pressure is applied to the front and back surfaces of the solar cell module 17, the protrusion 51 f of the second connection fitting 51 is caught inside the frame member 19 of the solar cell module 17, and the frame of the solar cell module 17. Since the member 19 is sandwiched between the second connection fitting 51 and the first or second fixing fitting 43, 44, the frame member 19 of the solar cell module 17 is not detached.

また、横桟15の主板15bの中心線S(図31(a)に示す)上にボルト孔15eが形成され、第2接続金具51の主板51bの中心線S上にネジ孔51eが形成されている。そして、太陽電池モジュール17を固定するためのボルト45がボルト孔15eを介してネジ孔51eにねじ込まれて、ボルト45が横桟15の主板15b及び第2接続金具51の主板51bの中心線S上に配置されている。   Further, a bolt hole 15e is formed on the center line S (shown in FIG. 31A) of the main plate 15b of the horizontal rail 15, and a screw hole 51e is formed on the center line S of the main plate 51b of the second connection fitting 51. ing. Then, a bolt 45 for fixing the solar cell module 17 is screwed into the screw hole 51e through the bolt hole 15e, and the bolt 45 is centerline S of the main plate 15b of the horizontal rail 15 and the main plate 51b of the second connection fitting 51. Is placed on top.

このように第2接続金具51の突起部51fが横桟15の中心線S上に概ね配置され、かつ第1又は第2固定金具43、44のボルト45も横桟15の中心線S上に配置されているので、風圧の影響による力が横桟15や太陽電池モジュール17の枠部材19をねじるように作用することは殆どなく、これらが変形することはない。   Thus, the protrusion 51f of the second connection fitting 51 is generally disposed on the center line S of the horizontal rail 15, and the bolts 45 of the first or second fixing bracket 43, 44 are also on the center line S of the horizontal rail 15. Since they are arranged, the force due to the influence of the wind pressure hardly acts to twist the horizontal beam 15 or the frame member 19 of the solar cell module 17, and these do not deform.

このねじれの力を防ぐには、第2接続金具51の突起部51fとボルト45が横桟15の中心線S上にあるのが理想的であるが、第2接続金具51の強度的な観点から突起部51fを形成するためのL字型切り込みエリアと側板51a間の距離を確保する必要があって、このために突起部51fが中心線Sからややずれた位置に設けられている。しかしながら、第1又は第2固定金具43、44のボルト45が横桟15の中心線S上にあるので、ねじれの力の影響が極力小さく抑えられている。   In order to prevent this twisting force, it is ideal that the protrusion 51f and the bolt 45 of the second connection fitting 51 are on the center line S of the horizontal rail 15. However, the strength of the second connection fitting 51 is considered. Therefore, it is necessary to secure a distance between the L-shaped cut area for forming the protrusion 51f from the side plate 51a and the protrusion 51f is provided at a position slightly shifted from the center line S. However, since the bolts 45 of the first or second fixing brackets 43 and 44 are on the center line S of the horizontal rail 15, the influence of the twisting force is minimized.

また、ボルト45を横桟15よりも十分に厚い第2接続金具51のネジ孔51eにねじ込んでいるので、太陽電池モジュール17にかかった風圧によりボルト45が引き抜かれることもない。   In addition, since the bolt 45 is screwed into the screw hole 51e of the second connection fitting 51 that is sufficiently thicker than the horizontal rail 15, the bolt 45 is not pulled out by wind pressure applied to the solar cell module 17.

すなわち、横桟15及び第2接続金具51により2重構造を構成し、かつ太陽電池モジュール17を固定するための突起部51f及びボルト45を横桟15の中心線S上に配し、かつボルト45を十分に厚い第2接続金具51のネジ孔51eにねじ込んだことにより、横桟15の耐荷重性が大幅に向上している。   That is, the horizontal beam 15 and the second connection fitting 51 constitute a double structure, and the protrusion 51f and the bolt 45 for fixing the solar cell module 17 are arranged on the center line S of the horizontal beam 15, and the bolt Since 45 is screwed into the screw hole 51e of the sufficiently thick second connection fitting 51, the load resistance of the crosspiece 15 is greatly improved.

次に、図33乃至図44を参照しつつ図1の太陽光発電システムの施工手順を整理して説明する。   Next, the construction procedure of the photovoltaic power generation system of FIG. 1 will be described with reference to FIGS. 33 to 44.

まず、図1に示すように複数のコンクリート基礎11を地面上に等間隔に形成し、それらの上面11-1を水平かつ面一として、水平な基礎面を形成する。   First, as shown in FIG. 1, a plurality of concrete foundations 11 are formed on the ground at equal intervals, and their upper surfaces 11-1 are horizontal and flush with each other to form a horizontal foundation surface.

図33に示すようにベース桟12をコンクリート基礎11の上面11-1に固定する。このとき、先に述べたようにコンクリート基礎11の上面11-1の2本のボルト21をベース桟12の主板12bの各長形孔12dに挿し通して、ベース桟12を載置し、ベース桟12をY方向に移動させて、Y方向の位置を調節する。そして、2個のコの字型補強金具22の孔にそれぞれのボルト21を通して、各コの字型補強金具22をベース桟12の内側に配置し、各ボルト21にそれぞれのナットをねじ込んで締め込み、ベース桟12を固定する。   As shown in FIG. 33, the base bar 12 is fixed to the upper surface 11-1 of the concrete foundation 11. At this time, as described above, the two bolts 21 on the upper surface 11-1 of the concrete foundation 11 are inserted into the respective elongated holes 12d of the main plate 12b of the base beam 12, and the base beam 12 is placed. The crosspiece 12 is moved in the Y direction to adjust the position in the Y direction. Then, the respective U-shaped reinforcing brackets 22 are arranged inside the base bar 12 through the respective bolts 21 through the holes of the two U-shaped reinforcing brackets 22, and the respective nuts are screwed into the respective bolts 21 and tightened. And fix the base bar 12.

図34に示すようにベース桟12の後端部内側にアーム13の各側板13aの下端部を差し込んで挟み込み、アーム13を自立させ、先に述べたようにアーム13の各側板13a間にパイプを挿入して、ボルトをパイプ、アーム13の各側板13aのボルト孔13d、ベース桟12の各側板12aのボルト孔12e、及びワッシャに通して、ボルトの一端にナットをねじ込んで締め込み、アーム13の各側板13aの下端部をベース桟12の各側板12aに固定する。   As shown in FIG. 34, the lower end portion of each side plate 13a of the arm 13 is inserted into the rear end portion inside the base rail 12 and sandwiched between them, so that the arm 13 is self-supported. As described above, the pipe is connected between the side plates 13a of the arm 13. The bolt is passed through the pipe, the bolt hole 13d of each side plate 13a of the arm 13, the bolt hole 12e of each side plate 12a of the base bar 12, and the washer, and a nut is screwed into one end of the bolt and tightened. The lower ends of the 13 side plates 13 a are fixed to the side plates 12 a of the base bar 12.

図35に示すようにベース12の先端部とアーム13の上端部に縦桟14を斜めに架け渡して固定する。ベース12の先端部と縦桟14の間、及びアーム13の上端部と縦桟14の間でも、パイプ、ボルト、ワッシャ、及びナット等を用いて、両者を接続する。   As shown in FIG. 35, a vertical beam 14 is obliquely bridged and fixed between the tip of the base 12 and the upper end of the arm 13. The pipe 12, the bolt, the washer, the nut, and the like are also connected between the tip of the base 12 and the vertical beam 14 and between the upper end of the arm 13 and the vertical beam 14.

図36に示すように縦桟14の主板14bに形成された一対のT字形孔14dに取付け金具31を取付ける。縦桟14の主板14bの3箇所に一対のT字形孔14dがそれぞれ形成されているので、それぞれの箇所に取付け金具31を取付ける。   As shown in FIG. 36, the mounting bracket 31 is attached to a pair of T-shaped holes 14d formed in the main plate 14b of the vertical beam 14. Since a pair of T-shaped holes 14d are formed at three locations on the main plate 14b of the vertical beam 14, the mounting bracket 31 is attached to each location.

図37に示すようにコンクリート基礎11毎に、ベース桟12、アーム13、及び縦桟14からなる三角構造を構築する。また、各縦桟14のいずれについても、主板14bの3箇所に取付け金具31を取付ける。   As shown in FIG. 37, for each concrete foundation 11, a triangular structure including a base beam 12, an arm 13, and a vertical beam 14 is constructed. In addition, for each of the vertical rails 14, mounting brackets 31 are attached to three locations on the main plate 14 b.

図38に示すように中央の横桟15となる桟部材151、152に、第1接続金具41及び補強金具42を取付ける。   As shown in FIG. 38, the first connection fitting 41 and the reinforcement fitting 42 are attached to the crosspiece members 151 and 152 that become the horizontal crosspiece 15 at the center.

図39に示すように上側及び下側の横桟15となる桟部材151、152に、第2接続金具51を取付ける。   As shown in FIG. 39, the 2nd connection metal fitting 51 is attached to the crosspieces 151 and 152 used as the upper and lower horizontal crosspieces 15. As shown in FIG.

図40に示すように最も右側の1番目と2番目の各コンクリート基礎11の縦桟14間に3本の桟部材151を架け渡し、縦桟14毎に、各桟部材151を縦桟14の3箇所の取付け金具31により固定する。中央の桟部材151が図38に示すように第1接続金具41及び補強金具42を取付けられたものであり、上側及び下側の桟部材151が図39に示すように第2接続金具51を取付けられたものである。このとき、各桟部材151をX方向に移動させて、X方向の位置を調節する。また、各桟部材151の間隔を調節する。   As shown in FIG. 40, three crosspiece members 151 are bridged between the vertical crosspieces 14 of the first and second concrete foundations 11 on the rightmost side, and each crosspiece member 151 is attached to the vertical crosspiece 14 for each vertical crosspiece 14. It is fixed with three mounting brackets 31. As shown in FIG. 38, the central crosspiece 151 is provided with the first connection fitting 41 and the reinforcing fitting 42, and the upper and lower crosspieces 151 are provided with the second connection fitting 51 as shown in FIG. It is attached. At this time, each crosspiece 151 is moved in the X direction to adjust the position in the X direction. Further, the interval between the crosspieces 151 is adjusted.

図41に示すように各桟部材151が各縦桟14の間隔よりも僅かに長く、各桟部材151の左側端部が2番目の縦桟14を超えて張り出している。   As shown in FIG. 41, each crosspiece member 151 is slightly longer than the interval between the vertical crosspieces 14, and the left end portion of each crosspiece member 151 extends beyond the second vertical crosspiece 14.

図41及び図42に示すように2番目の下側の桟部材152の片側端部152-1を、2番目の縦桟14から張り出した1番目の桟部材151の左側端部に載せて、各桟部材151、13の端部をパイプ、ボルト、ワッシャ、及びナット等により接続する。このとき、図10に示すように桟部材151、152のハット型断面形状の開口部側で各側板15aが広がっていることから、2番目の桟部材152の各側板15aの片側端部を1番目の桟部材151の各側板15aの左側端部に被せるようにするだけで、2番目の各側板15aの片側端部内側に1番目の各側板15aの左側端部を差し込んで挟み込むことができる。同時に、2番目の下側の桟部材152の左側端部を3番目の縦桟14上に載せて、この桟部材152の左側端部を縦桟14の取付け金具31により固定する。同様の手順で、2番目の中央及び上側の各桟部材152を1番目の中央及び上側の各桟部材151の左側端部と3番目の縦桟14間に架け渡して固定する。   As shown in FIGS. 41 and 42, the one end 152-1 of the second lower beam member 152 is placed on the left end of the first beam member 151 protruding from the second vertical beam 14, The ends of the crosspieces 151 and 13 are connected by pipes, bolts, washers, nuts, and the like. At this time, as shown in FIG. 10, each side plate 15a spreads out on the opening side of the hat-shaped cross-sectional shape of the crosspiece members 151 and 152, so that one end of each side plate 15a of the second crosspiece member 152 is 1 By simply covering the left end of each side plate 15a of the second cross member 151, the left end of each first side plate 15a can be inserted and sandwiched inside one end of each second side plate 15a. . At the same time, the left end of the second lower beam member 152 is placed on the third vertical beam 14, and the left end of the beam member 152 is fixed by the mounting bracket 31 of the vertical beam 14. In the same procedure, the second center and upper cross members 152 are bridged between the left end of each of the first center and upper cross members 151 and the third vertical cross 14 and fixed.

3番目の桟部材152については、図41に示すように2番目の桟部材152の左側端部が3番目の縦桟14を超えて張り出していることから、3番目の桟部材152を2番目の桟部材152の左側端部と4番目の縦桟14間に架け渡して固定する。   With respect to the third cross member 152, the left end of the second cross member 152 protrudes beyond the third vertical cross 14 as shown in FIG. It is bridged between the left end of the crosspiece member 152 and the fourth vertical crosspiece 14 and fixed.

以降同様に、n番目の桟部材152については、(n−1)番目の桟部材152の左側端部と(n+1)番目の縦桟14間に架け渡して固定する。   Similarly, the n-th beam member 152 is fixed between the left end portion of the (n−1) -th beam member 152 and the (n + 1) -th vertical beam 14.

図41及び図42から明らかなように各桟部材151、152の接続箇所近傍を縦桟14に載せて、横桟15を架設している。これにより各桟部材151、152の接続箇所が補強され、横桟15全体の強度の向上が図られている。   As apparent from FIGS. 41 and 42, the horizontal beam 15 is constructed by placing the vicinity of the connecting portion of the beam members 151 and 152 on the vertical beam 14. Thereby, the connection location of each crosspiece member 151 and 152 is reinforced, and the strength of the entire horizontal crosspiece 15 is improved.

図43に示すように偶数番目のベース桟12毎に、ベース桟12と中央の横桟15間に2本のトラス16を架け渡して、中央の横桟15を補強するためのトラス構造を構築する。   As shown in FIG. 43, for each even-numbered base beam 12, a truss structure for reinforcing the central horizontal beam 15 is constructed by spanning two trusses 16 between the base beam 12 and the central horizontal beam 15. To do.

図44に示すように上下左右の各太陽電池モジュール17の枠部材19を、第1接続金具41、第2接続金具51、第1固定金具43、及び第2固定金具44により固定する。このとき、先に述べたように中央の横桟15上で、下側の太陽電池モジュール17の枠部材19の内縁19aを下側の第1接続金具41の突起部41fに当接させて、下側の太陽電池モジュール17の上下位置を位置決めし、この後に上側の太陽電池モジュール17の枠部材19を下側の太陽電池モジュール17の枠部材19に当接させて、上側の太陽電池モジュール17の上下位置を位置決めする。   As shown in FIG. 44, the frame member 19 of each of the upper, lower, left, and right solar cell modules 17 is fixed by the first connection fitting 41, the second connection fitting 51, the first fixing fitting 43, and the second fixing fitting 44. At this time, as described above, the inner edge 19a of the frame member 19 of the lower solar cell module 17 is brought into contact with the protrusion 41f of the lower first connection fitting 41 on the central horizontal rail 15, The upper and lower positions of the lower solar cell module 17 are positioned, and thereafter, the frame member 19 of the upper solar cell module 17 is brought into contact with the frame member 19 of the lower solar cell module 17, so that the upper solar cell module 17. Position the vertical position of.

図44から明らかなように太陽電池モジュール17の側辺に対して、第1又は第2固定金具43、44を2個ずつ、第1及び第2接続金具41、51をそれぞれ1個ずつ配して、太陽電池モジュール17の側辺よりも短い間隔の2箇所で該側辺を固定している。このため、固定金具及び接続金具の配置間隔を狭くして、縦桟14の長さを太陽電池モジュール17の側辺よりも短くし、構造物設置用架台の小型化を図ることができる。   As is apparent from FIG. 44, two first or second fixing metal fittings 43 and 44 and one first and second connection metal fittings 41 and 51 are arranged on each side of the solar cell module 17. Thus, the side is fixed at two places with a shorter interval than the side of the solar cell module 17. For this reason, the arrangement | positioning space | interval of a fixing metal fitting and a connection metal fitting can be narrowed, the length of the vertical rail 14 can be made shorter than the side of the solar cell module 17, and size reduction of a structure installation stand can be achieved.

以上、本発明の実施形態を詳述したが、本発明は、上記実施形態に限定されるものではなく、本発明の要旨を逸脱しない範疇の設計変更等が施されたものであっても、本発明の範囲に含まれる。   As mentioned above, although the embodiment of the present invention has been described in detail, the present invention is not limited to the above-described embodiment, and even if a design change or the like in a category not departing from the gist of the present invention is performed, It is included in the scope of the present invention.

例えば、上記実施形態の架台は、ベース桟、アーム、縦桟、横桟、トラスを組み合わせて構築されているが、他の構造のものであってもよく、ベース桟、アーム、縦桟、トラスの代わりとなる部材を用いて、横桟を架け渡しても構わない。   For example, the gantry of the above embodiment is constructed by combining a base beam, an arm, a vertical beam, a horizontal beam, and a truss, but may have other structures, such as a base beam, an arm, a vertical beam, and a truss. A crosspiece may be bridged by using a member instead of.

また、複数の桟部材を接続して、横桟を構成しているが、縦桟、ベース桟等の他の種類の桟であっても、その長さが長くて、単一の部材で構成するのが困難な場合は、複数の桟部材を接続して、他の種類の桟を構成してもよい。   In addition, a plurality of crosspiece members are connected to form a horizontal crosspiece. However, other types of crosspieces such as a vertical crosspiece and a base crosspiece are long and constituted by a single member. When it is difficult to do this, a plurality of crosspiece members may be connected to form another type of crosspiece.

更に、上記実施形態では、図8に示すように桟部材152の片側端部152-1で主板15b及び各側板15aの一辺に沿う部分を切除し、各側板15a及び各鍔15cだけを残しているが、図45(a)に示すように桟部材152の片側端部152-1で、各側板15aの対向一辺に沿う部分15hを切除して、各側板15aを主板15bから分離させるだけでも構わない。この場合も、図45(b)、(c)に示すように桟部材152の各側板15aの片側端部152-1の内側又は外側に他の桟部材151又は152の各側板15aの端部を容易に重ね合わせることができる。   Further, in the above embodiment, as shown in FIG. 8, the main plate 15b and a portion along one side of each side plate 15a are cut off at one end portion 152-1 of the crosspiece member 152, leaving only the side plates 15a and the flanges 15c. However, as shown in FIG. 45 (a), at one end portion 152-1 of the crosspiece member 152, a portion 15h along the opposite side of each side plate 15a is cut away so that each side plate 15a is separated from the main plate 15b. I do not care. Also in this case, as shown in FIGS. 45 (b) and 45 (c), the end portions of the side plates 15a of the other cross members 151 or 152 inside or outside the one end portions 152-1 of the side plates 15a of the cross members 152. Can be easily superimposed.

また、図8及び図45(a)のいずれの桟部材152の片側端部152-1であっても、片側端部152-1の外側に他の桟部材151又は152の端部を被せて重ね合わせ、各桟部材の端部を接続することも可能である。   Further, in any one end portion 152-1 of the crosspiece member 152 in FIGS. 8 and 45 (a), the end portion of the other crosspiece member 151 or 152 is covered outside the one end portion 152-1. It is also possible to overlap and connect the end portions of the crosspiece members.

更に、図17(b)等に示すようにパイプ、ボルト、ナットを用いて、各桟を相互に接続するだけではなく、他の方法で接続しても構わない。例えば、図46に示すように桟部材の各側板15a間に筒状雌ねじ部材61を挿入し、2本のボルト62を各桟部材の各側板15aのボルト孔15fを通じて筒状雌ねじ部材61両端から該筒状雌ねじ部材61内側の雌ネジにそれぞれねじ込んで締め込むことにより各桟部材を接続してもよい。この場合も、筒状雌ねじ部材61が各側板15a間に挟みこまれて、該各側板が補強され、桟部材のハット型断面形状の変形を防ぐことができる。また、筒状雌ねじ部材61の長さと各側板間の離間距離が等しく、ナット等と比較して、筒状雌ねじ部材61のサイズが大きいため手作業での施工性が向上する。また、筒状雌ねじ部材61及び2本のボルト62を用いるだけであるから、部品点数、工数、及びコストを低減させることができる。   Furthermore, as shown in FIG. 17B and the like, the crosspieces may not only be connected to each other using pipes, bolts, and nuts, but may be connected by other methods. For example, as shown in FIG. 46, a cylindrical female screw member 61 is inserted between each side plate 15a of the cross member, and two bolts 62 are inserted from both ends of the cylindrical female screw member 61 through the bolt holes 15f of each side plate 15a of each cross member. The crosspiece members may be connected by screwing into the female screw inside the cylindrical female screw member 61 and tightening. Also in this case, the cylindrical female screw member 61 is sandwiched between the side plates 15a, the side plates are reinforced, and deformation of the cross-sectional shape of the crosspiece member can be prevented. Further, since the length of the cylindrical female screw member 61 is equal to the distance between the side plates, and the size of the cylindrical female screw member 61 is larger than that of a nut or the like, the workability in manual work is improved. Further, since only the cylindrical female screw member 61 and the two bolts 62 are used, the number of parts, man-hours, and cost can be reduced.

また、ベース桟、アーム、縦桟、横桟、トラスとして、一対の側板、各側板の対向一辺を連結する主板、及び各側板の縁で外側に折り曲げられたそれぞれの鍔からなるハット型断面形状を有するものを例示しているが、この代わりに、一対の側板及び各側板の対向一辺を連結する主板からなるコの字型断面形状を有するものを適用することができる。あるいは、これらの断面形状を適宜に組み合わせても構わない。   Also, a hat-shaped cross-sectional shape consisting of a pair of side plates, a main plate that connects opposite sides of each side plate, and each ridge bent outward at the edge of each side plate as a base beam, arm, vertical beam, horizontal beam, truss However, instead of this, it is possible to apply one having a U-shaped cross-sectional shape including a pair of side plates and a main plate that connects opposite sides of each side plate. Or you may combine these cross-sectional shapes suitably.

更に、第1接続金具41と補強金具42を併用しているが、第2接続金具51の内側に嵌合する補強金具を設けてもよい。これらの補強金具の断面形状は、ハット字型及びコの字型のいずれもよく、いずれであっても横桟15の断面形状を四角状の閉構造として、横桟15の強度を向上させることができる。   Furthermore, although the 1st connection metal fitting 41 and the reinforcement metal fitting 42 are used together, the reinforcement metal fitting fitted inside the 2nd connection metal fitting 51 may be provided. The cross-sectional shape of these reinforcing metal fittings may be either a hat-shaped or a U-shaped, and in any case, the cross-sectional shape of the horizontal beam 15 is a rectangular closed structure to improve the strength of the horizontal beam 15. Can do.

また、本実施形態の架台では、太陽電池モジュールを支持しいているが、この代わりに、太陽熱発電に用いられる反射鏡パネルを支持してもよい。これにより、太陽熱発電システムを構築することができる。   Moreover, in the mount frame of this embodiment, although the solar cell module is supported, you may support the reflector panel used for solar thermal power generation instead. Thereby, a solar thermal power generation system can be constructed.

更に、本実施形態では、主板端部および側板端部の一部を切除した形状としたが、主板と側板の接する部分(主板と側板間の一辺)に切り込みを入れるだけでも、各側板端部を弾性変形させることが可能となるため、桟部材の各側板端部の内側又は外側に他の桟部材の各側板端部を重ね合わせて、各桟部材を接続することができる。   Further, in the present embodiment, the main plate end and the side plate end are partially cut away, but each side plate end can be formed by only making a cut in a portion where the main plate and the side plate are in contact (one side between the main plate and the side plate). Can be elastically deformed, so that each cross member can be connected by overlapping each side plate end of another cross member on the inside or outside of each side plate end of the cross member.

また、本実施形態では、2個1組の第1接続金具41を桟15の中心線Sに対して上下対称に配置し、また、各ボルト45も横桟15の中心線Sに対して上下対称に配置しているが、同様の効果が得られる範囲において、各第1接続金具41もしくは各ボルト45を上下対称の位置から少しずれて配置してもよい。   Further, in the present embodiment, a set of two first connection fittings 41 are arranged vertically symmetrically with respect to the center line S of the crosspiece 15, and each bolt 45 is also vertically arranged with respect to the centerline S of the horizontal crosspiece 15. Although it arrange | positions symmetrically, in the range in which the same effect is acquired, you may arrange | position each 1st connection metal fitting 41 or each volt | bolt 45 a little from the vertically symmetrical position.

同様に、横桟15の主板15bのボルト孔15eを中心線S上に形成し、第2接続金具51のネジ孔51eを中心線S上に形成しているが、同様の効果が得られる範囲において、ボルト孔15eもしくはネジ孔51eを中心線Sから少しずらして形成してもよい。   Similarly, the bolt hole 15e of the main plate 15b of the cross rail 15 is formed on the center line S, and the screw hole 51e of the second connection fitting 51 is formed on the center line S. The bolt hole 15e or the screw hole 51e may be formed slightly shifted from the center line S.

また、本実施形態の架台では、材料として主に鋼鉄を用いているが、同一サイズ及び同一断面形状の桟部材同士で、一方の桟部材の各側板端部を他方の桟部材の各側板端部に重ねるには、人力により桟部材の各側板端部を該各側板の板厚分だけ弾性変形させる必要がある。このため、少なくとも桟部材の板厚を2.0mm以下にすることが望ましく、良好な施工性を実現するには、1.6mm以下であることが好ましい。一方、構造物を支持するための桟部材の強度を確保する必要もあるため、桟部材の板厚を0.5mm以上にするのが望ましい。   In addition, in the gantry of the present embodiment, steel is mainly used as a material, but each side plate end of one cross member is connected to each side plate end of the other cross member between cross members having the same size and the same cross-sectional shape. In order to overlap the portion, it is necessary to elastically deform each side plate end portion of the crosspiece member by the thickness of each side plate by human power. For this reason, it is desirable that the thickness of at least the crosspiece member is 2.0 mm or less, and in order to realize good workability, it is preferably 1.6 mm or less. On the other hand, since it is necessary to ensure the strength of the crosspiece member for supporting the structure, it is desirable that the thickness of the crosspiece member be 0.5 mm or more.

更に、第1もしくは第2接続金具の形状や構造を適宜変更しても構わない。図47は、太陽電池モジュール17を中央の横桟15に取り付けるための第1接続金具の変形例を示す斜視図である。また、図48は、図47の第1接続金具を中央の横桟に取付けた状態を示す断面図である。   Furthermore, you may change suitably the shape and structure of a 1st or 2nd connection metal fitting. FIG. 47 is a perspective view showing a modified example of the first connection fitting for attaching the solar cell module 17 to the central cross rail 15. FIG. 48 is a cross-sectional view showing a state where the first connection fitting of FIG. 47 is attached to the central cross rail.

この変形例の第1A接続金具71は、側板71a、側板71aの下縁で折り曲げられた底板71b、側板71aの上縁で折り曲げられた主板71c、主板71cの一辺両端部で折れ曲がって起こされた各突起部71e、主板71cの略中央に形成されたネジ孔71f、及び側板71aの略中央に形成されたボルト孔71gを有している。   The first-A connection fitting 71 of this modification was raised by bending the side plate 71a, the bottom plate 71b bent at the lower edge of the side plate 71a, the main plate 71c bent at the upper edge of the side plate 71a, and both ends of one side of the main plate 71c. Each projection 71e has a screw hole 71f formed in the approximate center of the main plate 71c, and a bolt hole 71g formed in the approximate center of the side plate 71a.

また、第1A接続金具71の側板71aにおけるボルト孔71gの上側位置には、コの字型の切り込みが入れられ、このコの字型の内側部分が側板71aから底板71b及び主板71cとは反対側に押出されて爪部71hとなっている。   Further, a U-shaped notch is formed at the upper position of the bolt hole 71g in the side plate 71a of the first A connection fitting 71, and this U-shaped inner portion is opposite to the bottom plate 71b and the main plate 71c from the side plate 71a. The claw portion 71h is pushed out to the side.

第1A接続金具71の底板71b下面から主板71c上面までの高さは、中央の横桟15の鍔15c上面から主板15b上面までの高さよりも高くなっている。具体的には、第1A接続金具71の主板71c上面までの高さが横桟15の主板15b上面までの高さよりも金具の板厚分だけ高くされている。   The height from the lower surface of the bottom plate 71b of the first A connection fitting 71 to the upper surface of the main plate 71c is higher than the height from the upper surface of the flange 15c of the central cross rail 15 to the upper surface of the main plate 15b. Specifically, the height to the upper surface of the main plate 71c of the first A connection fitting 71 is made higher by the plate thickness of the fitting than the height to the upper surface of the main plate 15b of the cross rail 15.

この第1A接続金具71は、図21(a)〜(c)の第1接続金具41と同様に、中央の横桟15の主板15bにおける一対のスリット15dとボルト孔15e(図3等を参照)の形成箇所にそれぞれ2個1組で配され、2個の第1A接続金具71の側板71aが横桟15の各側板15aに重ねられ、各第1A接続金具71の主板71cが横桟15から外向きに突出するように向けられ、各第1A接続金具71の各突起部71eが横桟15の主板15bよりも上方に突出する。   The first A connecting fitting 71 is similar to the first connecting fitting 41 shown in FIGS. 21A to 21C. The pair of slits 15d and the bolt holes 15e in the main plate 15b of the central cross rail 15 (see FIG. 3 and the like). ) Are arranged in pairs, and the side plates 71a of the two first A connection fittings 71 are overlapped on the side plates 15a of the horizontal rails 15, and the main plate 71c of each first A connection fitting 71 is connected to the horizontal rail 15 The protrusions 71e of the first A connecting fittings 71 protrude upward from the main plate 15b of the horizontal rail 15.

このとき、各第1A接続金具71の側板71aの爪部71hが横桟15の各側板15aの係合孔(図示せず)に係合して、各第1A接続金具71が横桟15の各側板15aに仮止めされる。ここでは、横桟15の各側板15aの適切箇所に係合孔が形成されているものとする。   At this time, the claw portion 71h of the side plate 71a of each 1A connection fitting 71 engages with an engagement hole (not shown) of each side plate 15a of the horizontal beam 15, and each 1A connection fitting 71 of the horizontal beam 15 Temporarily fixed to each side plate 15a. Here, it is assumed that an engagement hole is formed at an appropriate location of each side plate 15a of the cross rail 15.

また、先に述べたような第1A接続金具71の底板71b下面から主板71c上面までの高さ設定により、第1A接続金具71の主板71c上面が横桟15の主板15b上面よりも金具の板厚分だけ高くなる。   Further, by setting the height from the lower surface of the bottom plate 71b of the first A connection fitting 71 to the upper surface of the main plate 71c as described above, the upper surface of the main plate 71c of the first A connection fitting 71 is more than the upper surface of the main plate 15b of the cross rail 15. Increases by the thickness.

この状態で、横桟15の各側板15a間にパイプ72を挿入して、パイプ72、横桟15の各側板15aのボルト孔15f、及び各第1A接続金具71の側板71aのボルト孔71gを位置合わせし、ボルト73をパイプ72、横桟15の各側板15aのボルト孔15f、各第1A接続金具71の側板71aのボルト孔71g、及びワッシャに通して、ボルト73の一端にナット74をねじ込んで締め込み、各第1A接続金具71を横桟15に固定する。   In this state, the pipe 72 is inserted between the side plates 15a of the horizontal rail 15, and the pipe 72, the bolt holes 15f of the side plates 15a of the horizontal rail 15, and the bolt holes 71g of the side plates 71a of the first A connection fittings 71 are formed. The bolt 73 is passed through the pipe 72, the bolt hole 15 f of each side plate 15 a of the crosspiece 15, the bolt hole 71 g of the side plate 71 a of each 1A connection fitting 71, and a washer. The first A connection fittings 71 are fixed to the crosspieces 15 by screwing and tightening.

そして、図49に示すように太陽電池モジュール17の枠部材19を第1A接続金具71の各突起部71e間に入れて主板71c上に載置し、第2固定金具44(又は第1固定金具43)を太陽電池モジュール17の枠部材19に押し当てて、ボルト45を第2固定金具44のボルト孔44c(又は第1固定金具43のボルト孔43c)を介して第1A接続金具71の主板71cのネジ孔71fにねじ込んで締め込み、第2固定金具44(又は第1固定金具43)と第1A接続金具71の主板71c間に太陽電池モジュール17の枠部材19を挟み込んで固定する。   49, the frame member 19 of the solar cell module 17 is placed between the protrusions 71e of the first A connecting fitting 71 and placed on the main plate 71c, and the second fixing fitting 44 (or the first fixing fitting) is placed. 43) is pressed against the frame member 19 of the solar cell module 17, and the bolt 45 is pushed through the bolt hole 44c of the second fixing bracket 44 (or the bolt hole 43c of the first fixing bracket 43) to the main plate of the first A connecting bracket 71. The frame member 19 of the solar cell module 17 is sandwiched and fixed between the second fixing fitting 44 (or the first fixing fitting 43) and the main plate 71c of the first A connecting fitting 71 by screwing into the screw hole 71f of 71c.

この状態では、第1A接続金具71の主板71c上面が横桟15の主板15b上面よりも金具の板厚分だけ高くなっていることから、太陽電池モジュール17の枠部材19が横桟15の主板15b上面より浮き上がる。このため、太陽電池モジュール17の枠部材19と横桟15の主板15b間に水を逃がす経路が形成され、部材の錆びの発生を防止することができる。本実施形態では、金具の板厚分高くしたが、同目的のためには、桟の板厚分高くても同様の効果がある。   In this state, the upper surface of the main plate 71c of the first A connection fitting 71 is higher than the upper surface of the main plate 15b of the horizontal beam 15 by the thickness of the metal plate, so that the frame member 19 of the solar cell module 17 is the main plate of the horizontal beam 15. It floats from the upper surface of 15b. For this reason, a path for allowing water to escape is formed between the frame member 19 of the solar cell module 17 and the main plate 15b of the cross rail 15, and the occurrence of rusting of the member can be prevented. In the present embodiment, the metal plate is made thicker, but for the same purpose, the same effect can be obtained even if the crosspiece is made thicker.

図50は、第1接続金具の他の変形例を示す斜視図である。この変形例の第1B接続金具81は、側板81a、側板81aの下縁で折り曲げられた底板81b、側板81aの上縁で折り曲げられた主板81c、主板81cの一辺の複数箇所で折れ曲がって起こされた各突起部81e、主板81cに形成された2つのネジ孔81f、側板81aの複数箇所に形成されたボルト孔(図示せず)、及び2つの爪部81hを有している。この第1B接続金具81は、太陽電池モジュール17の幅よりも長くされている。   FIG. 50 is a perspective view showing another modification of the first connection fitting. The 1B connecting bracket 81 of this modified example is bent and raised at a plurality of locations on one side of the main plate 81c, the bottom plate 81b bent at the lower edge of the side plate 81a, the main plate 81c bent at the upper edge of the side plate 81a. Each projection 81e, two screw holes 81f formed in the main plate 81c, bolt holes (not shown) formed in a plurality of locations on the side plate 81a, and two claw portions 81h. The first B connection fitting 81 is longer than the width of the solar cell module 17.

各突起部81eが5個あり、各突起部81e間に4つの切り欠き部81i、81jが形成され、両端の2つの切り欠き部81iの箇所で主板81cのネジ孔81fがそれぞれ形成されている。2つのねじ孔81f間の距離は、太陽電池モジュール17の幅よりも若干長くされている。   There are five protrusions 81e, four notches 81i and 81j are formed between the protrusions 81e, and screw holes 81f of the main plate 81c are formed at the two notches 81i on both ends. . The distance between the two screw holes 81 f is slightly longer than the width of the solar cell module 17.

第1B接続金具81の底板81b下面から主板81c上面までの高さは、中央の横桟15の鍔15c上面から主板15b上面までの高さよりも金具の板厚分だけ高くされている。   The height from the bottom surface of the bottom plate 81b to the top surface of the main plate 81c of the first B connection fitting 81 is set higher than the height from the top surface of the flange 15c of the central cross rail 15 to the top surface of the main plate 15b by the thickness of the metal plate.

図51に示すように第1B接続金具81は、図47及び図48の第1A接続金具71と共に用いられる。第1B接続金具81が中央の横桟15の中央部に2個1組で配され、また第1A接続金具71が中央の横桟15の両端部にそれぞれ2個1組で配される。第1A接続金具71及び第1B接続金具81のいずれについても、それらの側板71a、81aが横桟15の各側板15aに重ねられ、それらの主板71c、81cが横桟15から外向きに突出するように向けられ、それらの突起部71e、81eが横桟15の主板15bよりも上方に突出する。また、それらの側板71a、81aの爪部71h、81hが横桟15の各側板15aの係合孔(図示せず)に係合して、第1A接続金具71及び第1B接続金具81が横桟15の各側板15aに仮止めされる。更に、それらの主板71c、81c上面が横桟15の主板15b上面よりも金具の板厚分だけ高くなる。   As shown in FIG. 51, the first B connection fitting 81 is used together with the first A connection fitting 71 shown in FIGS. The first B connection fittings 81 are arranged in pairs at the center of the central crosspiece 15, and the first A connection fittings 71 are arranged in pairs at both ends of the central crosspiece 15. In each of the first A connection fitting 71 and the first B connection fitting 81, the side plates 71a and 81a are overlapped on the side plates 15a of the horizontal beam 15, and the main plates 71c and 81c protrude outward from the horizontal beam 15. The protrusions 71e and 81e protrude upward from the main plate 15b of the horizontal rail 15. Further, the claw portions 71h and 81h of the side plates 71a and 81a are engaged with the engagement holes (not shown) of the side plates 15a of the horizontal rail 15, so that the first A connection fitting 71 and the first B connection fitting 81 are lateral. Temporarily fixed to each side plate 15a of the crosspiece 15. Furthermore, the upper surfaces of the main plates 71c and 81c are higher than the upper surface of the main plate 15b of the cross rail 15 by the thickness of the metal fitting.

この状態で、第1A接続金具71については図48と同様に、横桟15の各側板15a間にパイプ72を挿入して、ボルト73をパイプ72、横桟15の各側板15aのボルト孔15f、各第1A接続金具71の側板71aのボルト孔71g、及びワッシャに通して、ボルト73の一端にナット74をねじ込んで締め込み、各第1A接続金具71を横桟15に固定する。また、第1B接続金具81についても、横桟15の各側板15a間にパイプ72を挿入して、ボルト73をパイプ72、横桟15の各側板15aのボルト孔15f、各第1B接続金具81の側板81aのボルト孔、及びワッシャに通して、ボルト73の一端にナット74をねじ込んで締め込み、各第1B接続金具81を横桟15に固定する。第1B接続金具81の側板81aには4つのボルト孔が形成されているので、これらのボルト孔別に、パイプ72、ボルト73、及びナット74を用いて、第1B接続金具81を横桟15に固定する。   In this state, in the same way as in FIG. 48, for the first A connection fitting 71, the pipe 72 is inserted between the side plates 15a of the horizontal beam 15, the bolt 73 is connected to the pipe 72, and the bolt hole 15f of each side plate 15a of the horizontal beam 15. Then, the nuts 74 are screwed into one end of the bolts 73 and tightened by passing them through the bolt holes 71g of the side plates 71a of the first A connection fittings 71 and the washers, and the first A connection fittings 71 are fixed to the horizontal rails 15. As for the 1B connecting bracket 81, a pipe 72 is inserted between the side plates 15a of the horizontal rail 15, the bolt 73 is connected to the pipe 72, the bolt hole 15f of each side plate 15a of the horizontal rail 15, and the first B connecting bracket 81. Then, the nut 74 is screwed into one end of the bolt 73 and tightened to pass through the bolt hole of the side plate 81a and the washer, and each 1B connecting bracket 81 is fixed to the horizontal rail 15. Since the four bolt holes are formed in the side plate 81a of the first B connection fitting 81, the first B connection fitting 81 is attached to the horizontal rail 15 by using the pipe 72, the bolt 73, and the nut 74 for each of these bolt holes. Fix it.

この後、横桟15の一端部の第1A接続金具71と第1B接続金具81間に上下2枚の太陽電池モジュール17の枠部材19を載せ、第1B接続金具81にも上下2枚の太陽電池モジュール17の枠部材19を載せ、横桟15の他端部の第1A接続金具71と第1B接続金具81間にも上下2枚の太陽電池モジュール17の枠部材19を載せ、1本の横桟15に合計6枚の太陽電池モジュール17の枠部材19を載せる。   Thereafter, the frame members 19 of the upper and lower two solar cell modules 17 are placed between the first A connecting fitting 71 and the first B connecting fitting 81 at one end of the horizontal rail 15, and the upper and lower two solar panels are also placed on the first B connecting fitting 81. The frame member 19 of the battery module 17 is placed, and the frame members 19 of the two upper and lower solar cell modules 17 are also placed between the first A connection fitting 71 and the first B connection fitting 81 at the other end of the horizontal rail 15. A total of six frame members 19 of the solar cell modules 17 are placed on the horizontal rails 15.

第1A接続金具71では、図49に示すように太陽電池モジュール17の枠部材19を固定する。   In the first A connection fitting 71, the frame member 19 of the solar cell module 17 is fixed as shown in FIG.

また、第1B接続金具81では、両端の2つの切り欠き部81iの箇所が第1A接続金具71の各突起部71e間のスペースに相当し、左右に隣り合う2枚の太陽電池モジュール17の枠部材19を切り欠き部81iの箇所に入れて主板81c上に載置し、図27と同様に、第1固定金具43を各太陽電池モジュール17の枠部材19間に挿入して、ボルト45を第1固定金具43のボルト孔43cを介して第1B接続金具81の主板81cのネジ孔81fにねじ込んで締め込み、第1固定金具43と第1B接続金具81の主板81c間に各太陽電池モジュール17の枠部材19を挟み込んで固定する。   Moreover, in the 1B connection fitting 81, the location of the two notch portions 81i at both ends corresponds to the space between the projections 71e of the first A connection fitting 71, and the frame of the two solar cell modules 17 adjacent to the left and right. The member 19 is inserted into the cutout portion 81i and placed on the main plate 81c. Similarly to FIG. 27, the first fixing fitting 43 is inserted between the frame members 19 of the solar cell modules 17, and the bolts 45 are inserted. Each solar cell module is screwed into the screw hole 81 f of the main plate 81 c of the first B connection fitting 81 through the bolt hole 43 c of the first fixing fitting 43 and tightened between the first fixing fitting 43 and the main plate 81 c of the first B connection fitting 81. 17 frame members 19 are sandwiched and fixed.

また、両端の2つの切り欠き部81iに1枚の太陽電池モジュール17の枠部材19の両辺が配置され、この太陽電池モジュール17の枠部材19の両辺にそれぞれの第1固定金具43が押し当てられ、2本のボルト45がそれぞれの第1固定金具43のボルト孔43cを介して第1B接続金具81の主板81cのネジ孔81fにねじ込まれる。従って、2つのねじ孔81f間のスペースに太陽電池モジュール17を配置し得るように、各ねじ孔81f間の距離を太陽電池モジュール17の幅よりも若干長くしなければならない。   Further, both sides of the frame member 19 of one solar cell module 17 are arranged in the two notches 81 i at both ends, and the first fixing fittings 43 are pressed against both sides of the frame member 19 of the solar cell module 17. The two bolts 45 are screwed into the screw holes 81 f of the main plate 81 c of the first B connection fitting 81 through the bolt holes 43 c of the first fixing fittings 43. Therefore, the distance between each screw hole 81f must be slightly longer than the width of the solar cell module 17 so that the solar cell module 17 can be disposed in the space between the two screw holes 81f.

このような第1B接続金具81を第1A接続金具71と共に用いた場合も、第1A接続金具71の主板71c上面及び第1B接続金具81の主板81c上面が横桟15の主板15b上面よりも金具の板厚分だけ浮き上がることから、太陽電池モジュール17の枠部材19と横桟15の主板15b間に水を逃がす経路が形成され、部材の錆びの発生を防止することができる。   Even when such a first B connection fitting 81 is used together with the first A connection fitting 71, the upper surface of the main plate 71c of the first A connection fitting 71 and the upper surface of the main plate 81c of the first B connection fitting 81 are more fitting than the upper surface of the main plate 15b of the cross rail 15. Therefore, a path for allowing water to escape is formed between the frame member 19 of the solar cell module 17 and the main plate 15b of the horizontal rail 15, and the occurrence of rusting of the member can be prevented.

また、第1B接続金具81が太陽電池モジュール17の幅よりも長いことから、第1B接続金具81の側板81a及び底板81bが中央の横桟15の側板15a及び鍔15cに重なる距離が長くなり、第1B接続金具81が中央の横桟15に固定されると、この中央の横桟15が効果的に補強される。従って、第1B接続金具81は、3枚の太陽電池モジュール17の枠部材19を支持するだけではなく、中央の横桟15の補強具としての役目を果たす。中央の横桟15には、上側及び下側の横桟15よりも大きな荷重がかかることから、そのような中央の横桟15の補強は有益である。   In addition, since the first B connection fitting 81 is longer than the width of the solar cell module 17, the distance that the side plate 81a and the bottom plate 81b of the first B connection fitting 81 overlap the side plate 15a and the flange 15c of the central cross rail 15 is increased. When the 1B connecting bracket 81 is fixed to the central crosspiece 15, the central crosspiece 15 is effectively reinforced. Accordingly, the first B connection fitting 81 not only supports the frame members 19 of the three solar cell modules 17 but also serves as a reinforcing tool for the central horizontal rail 15. Since a larger load is applied to the central side rail 15 than the upper and lower side rails 15, such reinforcement of the central side rail 15 is beneficial.
