Description

本発明は、特にメガソーラー等の大規模太陽光発電施設として、平地及び傾斜地を含む地上ならびにビル屋上の如き陸屋根に設置する太陽電池アレイの据付装置に関する。   The present invention relates to a solar cell array installation apparatus that is installed on a flat roof, such as a flat roof and an inclined land, and a flat roof such as a building roof, particularly as a large-scale photovoltaic power generation facility such as a mega solar.

近年、環境保護、省資源、CO2 削減等の観点から、平地及び傾斜地を含む地上やビル屋上の如き陸屋根に、多数基の太陽電池アレイを並設したメガソーラー等の大規模太陽光発電施設が普及しつつある。しかるに、一般的に太陽電池アレイは、複数枚の太陽電池モジュールを平面的に並べた短辺数m、長辺数m〜数十mといった大型のパネル形態で重い上、受光効率面より所定の傾斜角度で配置することで風圧を受け易いため、その据付け部には大きな支持強度及び耐風圧強度が必要であり、また全体としての軽量化、据付施工の容易化、コスト削減等も要求される。 In recent years, from the viewpoints of environmental protection, resource saving, CO 2 reduction, etc., large-scale photovoltaic power generation facilities such as mega-solar power generation systems, where a large number of solar cell arrays are arranged side by side on a flat roof such as the ground or a building roof, including flat and sloping land Is spreading. However, in general, the solar cell array is heavy in the form of a large panel having a short side number of m and a long side number of m to several tens of meters, in which a plurality of solar cell modules are arranged in a plane, and more predetermined than the light receiving efficiency surface Because it is easy to receive wind pressure by placing it at an inclination angle, the installation part needs to have a large support strength and wind pressure strength, and it is also required to reduce the overall weight, facilitate installation work, reduce costs, etc. .

従来、このような太陽電池アレイを地上や陸屋根に据付けする手段として、コンクリート製の杭や土台をベースとして型鋼材等による架台を構築し、この架台上に太陽電池アレイを設置する方式が多用されている。そして、該架台としては、複数の支柱を太陽電池アレイの長手方向(左右方向)に沿って間隔をあけて突設し、各支柱の上端部を太陽電池アレイを支承する架台フレームの短辺方向(前後傾斜方向)に沿う縦桟の中間位置に接続すると共に、各支柱の胴部と各縦桟の前部側又は前後両側部との間に傾斜アームを連結した構造(特許文献1)や、太陽電池アレイの架台フレームを前後及び左右に配列した支柱で支承すると共に、前後及び左右に隣接する支柱間に斜めや水平の補強桟を連結した構造(特許文献2)が代表的である。   Conventionally, as a means for installing such a solar cell array on the ground or on a flat roof, a method of constructing a frame made of a steel plate or the like based on a concrete pile or base and installing the solar cell array on the frame is often used. ing. As the gantry, a plurality of support columns are projected along the longitudinal direction (left-right direction) of the solar cell array at intervals, and the upper end portion of each support column is in the short side direction of the gantry frame that supports the solar cell array. A structure (Patent Document 1) in which an inclined arm is connected between the middle portion of each column and the front side of each vertical beam or both front and rear sides thereof, while being connected to an intermediate position of the vertical beam along the (front-rear inclination direction) A structure in which the frame of the solar cell array is supported by pillars arranged in the front-rear and left-right directions, and diagonal and horizontal reinforcing bars are connected between the pillars adjacent in the front-rear and left-right directions (Patent Document 2) is representative.

特開2011−220096号公報(図1,図42,図43)Japanese Patent Laying-Open No. 2011-220096 (FIGS. 1, 42, and 43) 実用新案登録第3171824号公報(図1)Utility Model Registration No. 3171824 (FIG. 1)

上記前者のように各支柱の上端部を架台フレームの縦桟の中間位置に接続する構造では、太陽電池アレイの短辺方向について一本の支柱で支える形になるため、耐荷重面より支柱を非常に太くする必要がある上、地形等から強風に晒され易い場所では風圧に対して充分な支持強度及び耐風圧強度を確保することが困難であり、据付場所の制約が大きいという難点があった。また、上記後者の架台フレームを前後及び左右に配列した支柱で支承する構造では、太陽電池アレイの矩形単位の重量負荷が前後左右の四本の支柱に分散されると共に、支柱間が補強桟で繋がれることで架台構体としての強度も大きくなるが、全体重量を軽減する目的で架台フレームを含めた構造材に中空アルミ材を用いた場合、型鋼材に比較して強度的に劣ることから、特に支柱として剛性を確保するために太いものを必要とし、それだけ材料コストが嵩むと共に、四本の支柱で支承する太陽電池アレイの矩形単位のサイズが大きくなると、該矩形単位の中央側で架台フレームが撓み変形し易く、太陽光発電パネルの損傷や発電効率低下に繋がる懸念があった。   In the structure where the upper end of each column is connected to the middle position of the vertical frame of the mount frame as in the former case, the column is supported by a single column in the short side direction of the solar cell array. In addition to being very thick, it is difficult to ensure sufficient support strength and wind pressure resistance against wind pressure in locations that are easily exposed to strong winds from topography, etc. It was. Further, in the structure in which the latter frame is supported by the columns arranged in the front and rear and left and right, the weight load of the rectangular unit of the solar cell array is distributed to the four columns of the front and rear and the left and right, and the reinforcing bars are provided between the columns. By connecting, the strength as a gantry structure also increases, but when using a hollow aluminum material for the structural material including the gantry frame for the purpose of reducing the overall weight, it is inferior in strength compared to the type steel material, In particular, a thick column is required to secure rigidity as the column, and the material cost increases accordingly. When the size of the rectangular unit of the solar cell array supported by the four columns is increased, the frame on the center side of the rectangular unit However, there is a concern that the solar power generation panel is damaged and power generation efficiency is reduced.

本発明は、上述の事情に鑑みて、太陽電池アレイの据付装置として、架台フレームを含めた構造材に中空アルミ材を用いて全体重量を軽減した構成において、支柱として軽く細いものを使用しても架台構体として高強度であり、強風に晒され易い場所でも充分な支持強度及び耐風圧強度を確保できる上、太陽電池アレイの矩形単位のサイズが大きくなっても中央側での架台フレームの撓み変形を防止でき、また太陽電池アレイの全体サイズの違いにも共通部材を用いて対応できると共に、施工容易なものを提供することを目的としている。   In view of the above-mentioned circumstances, the present invention uses a light and thin column as a mounting device for a solar cell array in a configuration in which the overall weight is reduced by using a hollow aluminum material for a structural material including a gantry frame. In addition, it has high strength as a gantry structure, and it can secure sufficient support strength and wind pressure strength even in a place where it is easily exposed to strong winds, and even if the size of the rectangular unit of the solar cell array becomes large, the gantry frame bends at the center side. An object of the present invention is to provide a device that can prevent deformation, can cope with a difference in the overall size of the solar cell array by using a common member, and is easy to construct.

Being done.

次に、本発明の効果について図面の参照符号を付して説明する。まず、請求項1の発明に係る太陽電池アレイの据付装置では、複数本の縦桟11及び横桟12が格子状に連結された架台フレーム1は、これに支承される太陽電池アレイ10の矩形単位U毎に前後左右の四本の垂直支柱2で支持されるが、該架台フレーム1及び垂直支柱2と複数本のブレース3との間で構成するトラス構造により、架台構体として非常に高強度になる。従って、強風に晒され易い場所でも大きな支持強度及び耐風圧強度を確保でき、据付け場所の制約が少ない上、太陽電池アレイ10の矩形単位Uのサイズが大きくなっても、ブレース3による支持位置を該矩形単位Uの中央側に設定することで、該中央側での架台フレーム1の撓み変形を防止できる。また、架台フレーム1の縦桟11及び横桟12、垂直支柱2、ブレース3、該ブレース3を架台フレーム1に取り付けるブレース取付桟13がいずれも軽量な中空アルミ材であるため、据付装置全体としての重量が軽減すると共に、その据付け施工時の作業性も向上する。加えて、上記のように架台構体として高強度であるため、垂直支柱2に軽く細い中空アルミ材を用いることで材料コストも低減される。そして、架台フレーム1に組み付けられるブレース取付桟13が円筒状をなし、このブレース取付桟13に外嵌して固定される止着金具4を介して、ブレース3の上端側を該ブレース取付桟13に止着する構造であり、該ブレース3の傾斜角度及び傾斜方向が種々異なっていても、同じ止着金具4を用いてブレース取付桟13に対する嵌合位置と回転姿勢を調整することで対応できるから、太陽電池アレイの全体サイズの違いにも共通部材を使用することが可能となり、それだけ材料コストを低減できると共に、同じ操作手順で該ブレース3を止着できるので施工作業も容易になる。   Next, effects of the present invention will be described with reference numerals in the drawings. First, in the solar cell array installation apparatus according to the first aspect of the present invention, the gantry frame 1 in which a plurality of vertical bars 11 and horizontal bars 12 are connected in a grid pattern is a rectangular shape of the solar cell array 10 supported by the frame. Each unit U is supported by four vertical struts 2 on the front, rear, left and right sides. The truss structure formed between the frame 1 and the vertical struts 2 and a plurality of braces 3 makes the frame structure very strong. become. Therefore, a large support strength and wind pressure strength can be ensured even in a place that is easily exposed to strong winds, and there are few restrictions on the installation location, and even if the size of the rectangular unit U of the solar cell array 10 increases, the support position by the brace 3 By setting to the center side of the rectangular unit U, it is possible to prevent bending deformation of the gantry frame 1 on the center side. Further, since the vertical beam 11 and the horizontal beam 12, the vertical column 2, the brace 3, and the brace mounting frame 13 for attaching the brace 3 to the frame 1 are all made of a lightweight hollow aluminum material, The weight of the machine is reduced, and the workability during installation is improved. In addition, since the frame structure has high strength as described above, the material cost can be reduced by using a light and thin hollow aluminum material for the vertical support 2. The brace mounting bar 13 to be assembled to the gantry frame 1 has a cylindrical shape, and the brace mounting bar 13 is connected to the upper end side of the brace 3 via a fastening metal fitting 4 that is externally fitted and fixed to the brace mounting bar 13. Even if the inclination angle and the inclination direction of the brace 3 are variously different, it can be dealt with by adjusting the fitting position and the rotation posture with respect to the brace mounting bar 13 by using the same fixing bracket 4. Therefore, it is possible to use a common member for the difference in the overall size of the solar cell array, so that the material cost can be reduced accordingly, and the bracing 3 can be fastened by the same operation procedure, so that the construction work is facilitated.

請求項2の発明によれば、止着金具4は、ブレース取付桟13を挿嵌させる円環部4aから一対のブレース取付片4b,4bが外側へ延出し、両ブレース取付片4b,4b間にブレース3の上端側を挟んで枢着するものであるから、据付け施工に際して予めブレース取付桟13に嵌装しておいて、ブレース3の先端側の向きと位置に応じて、ブレース取付桟13に対する嵌合位置と回転姿勢を調整することにより、該ブレース3の止着操作が極めて容易になる。   According to the invention of claim 2, the fastening bracket 4 has a pair of brace mounting pieces 4b, 4b extending outward from an annular portion 4a into which the brace mounting bar 13 is inserted, and between the brace mounting pieces 4b, 4b. Since the upper end side of the brace 3 is sandwiched between the brace 3 and the brace mounting bar 13, the brace mounting bar 13 is fitted in advance to the brace mounting bar 13 during installation. By adjusting the fitting position and the rotation posture with respect to the brace 3, the fastening operation of the brace 3 becomes extremely easy.

請求項3の発明によれば、ブレース取付桟13と平行方向に隣接する垂直支柱2,2の根元部間に、中空アルミ材からなる円筒状の胴桟14が架設され、この胴桟14に各ブレース3の下端側を上端側と同様の止着金具4を介して枢着する構成であるから、該ブレース3に加わる荷重の負荷が垂直支柱2の根元側で受け止められ、該負荷が垂直支柱2に対する曲げ力として作用しにくいため、該垂直支柱2が細い中空アルミ材であっても充分な耐久性が得られると共に、ブレース3の下端側についても上端側と同様に傾斜角度及び傾斜方向の違いに関わらず同じ止着金具4を利用して容易に止着作業を行える。   According to the third aspect of the present invention, the cylindrical trunk bar 14 made of a hollow aluminum material is installed between the base portions of the vertical columns 2 and 2 adjacent in parallel to the brace mounting bar 13. Since the lower end side of each brace 3 is pivotally attached via a fastening member 4 similar to the upper end side, the load of the load applied to the brace 3 is received at the base side of the vertical support column 2, and the load is vertical. Since it is difficult to act as a bending force on the support 2, sufficient durability can be obtained even if the vertical support 2 is a thin hollow aluminum material, and the lower end side of the brace 3 is inclined and in the same direction as the upper end. Regardless of the difference, it is possible to easily perform the fastening operation using the same fastening bracket 4.

請求項4の発明によれば、各ブレース3は、前後及び左右に隣接した4本の垂直支柱2位置を頂点とする矩形内の中央寄り位置でブレース取付桟13に上端側を止着すると共に、下端側を垂直支柱2の根元近傍に止着することにより、前後及び左右の両方向に対して傾斜しているから、上記矩形単位のサイズが大きくなっても、その中央側での架台フレーム1の撓み変形を防止できる上、架台構体が左右及び前後の両方向でトラス構造を構成する形で極めて高強度になる。   According to the invention of claim 4, each brace 3 is fastened to the brace mounting bar 13 at the position near the center in the rectangle with the four vertical struts 2 adjacent to the front and rear and the left and right as vertices. Since the lower end side is fixed to the vicinity of the base of the vertical column 2, the frame is inclined with respect to both the front and rear and left and right directions. In addition to preventing the bending deformation of the frame structure, the gantry structure is extremely high in strength by forming a truss structure in both the left and right and front and rear directions.

なお、止着金具4、ブラケット5Aのブラケット本体51及び縦桟抱持金具52、ブラケット5B、結合金具6の上下部材6A,6B、連結金具7、上向き抱持枠部7a、取付金具9の抱持枠部91は、いずれもアルミ型材の切断短材からなる。そして、これらアルミ型材ならびに既述の中空アルミ型材は、アルミニウム及びアルミニウム合金からなるものを包含する。   It should be noted that the fastening bracket 4, the bracket body 51 of the bracket 5 </ b> A and the vertical beam holding bracket 52, the bracket 5 </ b> B, the upper and lower members 6 </ b> A and 6 </ b> B of the coupling bracket 6, the connecting bracket 7, the upward holding frame portion 7 a, and the mounting bracket 9. Each of the holding frame portions 91 is made of a short cut material of an aluminum mold material. The aluminum mold material and the hollow aluminum mold material described above include those made of aluminum and aluminum alloys.

上記構成の太陽電池アレイの据付装置では、太陽電池アレイ10を支承する架台フレーム1は該太陽電池アレイ10の矩形単位U毎に前後左右の四本の垂直支柱2で支持されるが、該矩形単位U毎に4本のブレース3が前後方向及び左右方向に傾斜して配置していることにより、架台フレーム1、垂直支柱2、ブレース3、胴桟14、補強桟16よりなる架台構体がトラス構造を形成して非常に高強度になり、強風に晒され易い場所でも大きな支持強度及び耐風圧強度を確保でき、据付け場所の制約が少なくなる。また、架台フレーム1の縦桟11及び横桟12、垂直支柱2、ブレース3、ブレース取付桟13、胴桟14、補強桟16がいずれも軽量な中空アルミ材であるため、据付装置全体としての重量が軽減すると共に、その据付け施工時の作業性も向上する。加えて、上記のように架台構体として高強度であるため、垂直支柱2に軽く細い中空アルミ材を用いることで材料コストも低減される。   In the solar cell array installation apparatus having the above-described configuration, the gantry frame 1 that supports the solar cell array 10 is supported by four vertical columns 2 on the front, rear, left, and right for each rectangular unit U of the solar cell array 10. Since four braces 3 are inclined in the front-rear direction and the left-right direction for each unit U, the frame structure including the frame 1, the vertical column 2, the brace 3, the body frame 14, and the reinforcement frame 16 is trussed. A structure is formed so that the strength becomes very high, and a large support strength and wind pressure strength can be secured even in a place that is easily exposed to strong winds, and there are less restrictions on the installation location. In addition, since the vertical beam 11 and the horizontal beam 12, the vertical column 2, the brace 3, the brace mounting frame 13, the body frame 14, and the reinforcing frame 16 of the gantry frame 1 are all lightweight hollow aluminum materials, The weight is reduced, and the workability during installation is improved. In addition, since the frame structure has high strength as described above, the material cost can be reduced by using a light and thin hollow aluminum material for the vertical support 2.

加えて上記実施形態では、各ブレース3による支持位置が前記矩形単位Uにおける前後左右の4本の垂直支柱2の位置を頂点とする矩形内の中央側にあるから、該矩形単位Uのサイズが大きくなっても、該中央側での架台フレーム1の撓み変形を防止でき、その撓み変形に伴う太陽光発電パネルPの損傷や発電効率低下を回避できると共に、各ブレース3に加わる荷重の負荷が垂直支柱2の根元側で受け止められ、該負荷が垂直支柱2に対する曲げ力として作用しにくいため、該垂直支柱2が細い中空アルミ材であっても充分な耐久性が得られる。   In addition, in the above-described embodiment, the support position by each brace 3 is on the center side in the rectangle with the positions of the four vertical struts 2 on the front, rear, left and right in the rectangular unit U as the apexes. Even if it becomes larger, it is possible to prevent the deformation of the gantry frame 1 at the center side, to avoid damage to the photovoltaic power generation panel P and a decrease in power generation efficiency due to the bending deformation, and to apply a load applied to each brace 3. Since it is received on the base side of the vertical support 2 and the load is less likely to act as a bending force on the vertical support 2, sufficient durability can be obtained even if the vertical support 2 is a thin hollow aluminum material.

そして、架台フレーム1に組み付けられるブレース取付桟13と、垂直支柱2の下端部間に架設される胴桟14とが円筒状をなし、これらブレース取付桟13及び胴桟14に外嵌して固定される止着金具4を介して、各ブレース3の上下端部をブレース取付桟13及び胴桟14に止着する構造であるため、各ブレース3の傾斜角度及び傾斜方向が異なるにも関わらず、同じ止着金具4を用いてブレース取付桟13及び胴桟13に対する嵌合位置と回転姿勢を調整することで対応でき、太陽電池アレイ10の全体サイズの違いにも共通部材を使用することが可能となり、それだけ材料コストを低減できると共に、各ブレース3を同じ操作手順で止着できるので施工作業も容易になる。   The brace mounting bar 13 assembled to the gantry frame 1 and the body frame 14 installed between the lower end portions of the vertical column 2 form a cylindrical shape, and are fitted and fixed to the brace mounting frame 13 and the body frame 14. Since the upper and lower end portions of each brace 3 are fixed to the brace mounting bar 13 and the trunk bar 14 via the fixing metal fitting 4 that is made, the inclination angle and the inclination direction of each brace 3 are different. It is possible to cope with the problem by adjusting the fitting position and the rotation posture with respect to the brace mounting bar 13 and the body bar 13 using the same fastening metal fitting 4, and a common member can be used for the difference in the overall size of the solar cell array 10. Thus, the material cost can be reduced accordingly, and each brace 3 can be fixed by the same operation procedure, so that the construction work is facilitated.

特に、上記実施形態における止着金具4では、ブレース取付桟13又は胴桟14を挿嵌させる円環部4aから一対のブレース取付片4b,4bが外側へ延出し、両ブレース取付片4b,4b間にブレース3の上下端部を挟んで枢着するから、据付け施工に際して予めブレース取付桟13及び胴桟14に嵌装しておいて、ブレース3の先端側の向きと位置に応じて、ブレース取付桟13及び胴桟14に対する嵌合位置と回転姿勢を調整することにより、該ブレース3の止着操作が極めて容易になるという利点がある。更に、ブレース取付桟13が架台フレーム1の隣接する縦材11,11間にブラケット5Aを介して架設され、このブラケット5Aがブレース取付桟13を挿嵌させる円環部51aと架台フレーム1の縦材11に取り付ける桟抱持金具52とを備えるから、架台フレーム1に対して該ブレース取付桟13を容易に且つ確実に強固に取り付けることができる。   In particular, in the fastening bracket 4 in the above-described embodiment, the pair of brace mounting pieces 4b and 4b extend outward from the annular portion 4a into which the brace mounting bar 13 or the trunk bar 14 is inserted, and both brace mounting pieces 4b and 4b. Since the upper and lower end portions of the brace 3 are sandwiched between them, the brace is fitted in advance to the brace mounting bar 13 and the body bar 14 at the time of installation work, and the brace according to the direction and position of the front end side of the brace 3 By adjusting the fitting position and the rotational posture with respect to the mounting bar 13 and the body bar 14, there is an advantage that the fastening operation of the brace 3 becomes extremely easy. Further, a brace mounting bar 13 is installed between adjacent vertical members 11 and 11 of the gantry frame 1 via a bracket 5A, and the bracket 5A is inserted between the annular part 51a into which the brace mounting bar 13 is inserted and the vertical frame of the gantry frame 1. Since the crosspiece mounting bracket 52 attached to the material 11 is provided, the brace mounting crosspiece 13 can be easily and securely attached firmly to the gantry frame 1.

一方、架台フレーム1の縦桟11と横桟12とが結合金具6を介して結合され、その縦桟11又は横桟12に対して各垂直支柱2が上端部で連結金具7を介して連結固定される構成であるから、傾斜配置される架台フレーム1を各垂直支柱2に対して容易に且つ確実に強固に取り付けることができる。また、結合金具6及び連結金具7が抱持枠部6a,6b,7aで架台フレーム1の角筒状の縦桟11及び/又は横桟12を抱持し、その抱持位置において側方から貫通させたボルトBにナットNを螺合緊締することから、両金具6,7の該縦桟11及び/又は横桟12に対する取付け部分が高強度になると共に、その取付け作業を容易に且つ確実に行える。特に、実施形態のように連結金具7による横桟12と垂直支柱2の連結位置に鋼製の補強パイプ15を挿嵌し、その挿嵌部分に前記ボルトBを貫通させる構成では、架台フレーム1に対する該垂直支柱2の固定部分が極めて高強度となり、それだけ架台構体としての強度も向上する。   On the other hand, the vertical beam 11 and the horizontal beam 12 of the gantry frame 1 are coupled via the coupling bracket 6, and each vertical column 2 is coupled to the vertical beam 11 or the lateral beam 12 via the coupling bracket 7 at the upper end. Because of the fixed configuration, the gantry frame 1 that is inclined can be easily and securely attached to each vertical column 2 firmly. Further, the coupling metal 6 and the coupling metal 7 hold the vertical cylindrical beam 11 and / or the horizontal beam 12 of the gantry frame 1 by the holding frame portions 6a, 6b, 7a, and from the side at the holding position. Since the nut N is screwed and tightened to the bolt B that has been passed through, the attachment portions of the metal fittings 6 and 7 to the vertical beam 11 and / or the horizontal beam 12 become high in strength, and the installation work is easy and reliable. It can be done. In particular, in the configuration in which the steel reinforcing pipe 15 is inserted into the connecting position of the horizontal beam 12 and the vertical column 2 by the connecting metal fitting 7 as in the embodiment, and the bolt B is passed through the insertion portion, the frame 1 The fixing portion of the vertical column 2 with respect to is extremely high in strength, and the strength as a frame structure is improved accordingly.

更に、実施形態の如く架台フレーム1の角筒状の縦桟11及び横桟12の上下部が幅広の角枠部11a,12aを形成し、結合金具6及び連結金具7の各抱持枠部6a,6b,7aが該角枠部11a,12aを上下方向離脱不能で且つ長手方向摺動可能に抱持する構成では、据付け施工に際し、架台フレーム1の縦桟11及び横桟12に対して予め両金具6,7を嵌装しておき、組み付け時に必要位置まで移動させることで、その作業操作をより容易に行えるという利点がある。   Further, as in the embodiment, the upper and lower portions of the rectangular columnar vertical beam 11 and the horizontal beam 12 of the gantry frame 1 form wide rectangular frame portions 11a and 12a, and the holding frame portions of the coupling metal 6 and the coupling metal 7 are formed. 6a, 6b, 7a is configured to hold the square frame portions 11a, 12a so as not to be vertically disengageable and slidable in the longitudinal direction, with respect to the vertical beam 11 and the horizontal beam 12 of the gantry frame 1 during installation work. There is an advantage that the work operation can be performed more easily by fitting both the metal fittings 6 and 7 in advance and moving them to the required position at the time of assembly.

加えて、実施形態の結合金具6及び連結金具7では、架台フレーム1の角筒状の縦桟11及び横桟12に対して連結金具7をボルトBとナットNを用いて取り付ける際、そのナットNの螺合緊締により、抱持枠部6a,6b,7aの対向する内面側の一対の凸条部63,63、68,68、72,72が縦桟11及び横桟12の凹陥部11b,12bに押接するから、該ナットNによる締付力が広面積に分散して加わるから、該締付力の局所的集中による縦桟11及び横桟12の歪み変形を生じにくく、それだけ締付力を大きくして強固な結合状態にすることができるという利点がある。本実施形態の場合、このような締付力の分散による歪み変形の抑制効果は、ブラケット5Aの縦桟抱持金具52による縦桟11に対する固定部や、取付金具9の抱持枠部91による縦桟11に対する固定部でも同様に得られる。なお、特に連結金具7による横桟12と垂直支柱2の連結位置に前記の補強パイプ15を挿嵌する構成では、実施形態のように横桟12の両側の凹陥部12b,12bの各々内面側にも長手方向に沿う一対の凸条12c,12cを設け、ナットNの螺合緊締による締付力が凸条12c,12cを介して補強パイプ15に加わるようにすれば、該横桟12の歪み変形をより確実に防止できる。   In addition, in the coupling bracket 6 and the coupling bracket 7 of the embodiment, when the coupling bracket 7 is attached to the rectangular cylindrical vertical beam 11 and the horizontal beam 12 of the gantry frame 1 using the bolt B and the nut N, the nut By screwing and tightening N, the pair of protruding strips 63, 63, 68, 68, 72, 72 on the inner surface facing the holding frame portions 6a, 6b, 7a are formed into the vertical beam 11 and the recessed portion 11b of the horizontal beam 12. , 12b, so that the tightening force by the nut N is distributed over a wide area, so that the vertical beam 11 and the horizontal beam 12 are not easily deformed due to local concentration of the tightening force, and the tightening is performed accordingly. There is an advantage that the force can be increased to form a strong bonded state. In the case of the present embodiment, the effect of suppressing distortion deformation due to such dispersion of the tightening force is due to the fixing portion of the bracket 5A to the vertical beam 11 by the vertical beam holding bracket 52 and the holding frame portion 91 of the mounting bracket 9. It can be obtained in the same manner in the fixed portion with respect to the vertical beam 11. In particular, in the configuration in which the reinforcing pipe 15 is inserted into the connecting position of the horizontal beam 12 and the vertical column 2 by the connecting bracket 7, each of the recessed portions 12b, 12b on the both sides of the horizontal beam 12 as shown in the embodiment. If a pair of ridges 12c, 12c along the longitudinal direction is provided and the tightening force by screwing and tightening the nut N is applied to the reinforcing pipe 15 via the ridges 12c, 12c, Strain deformation can be prevented more reliably.

本発明を適用する太陽電池アレイ10としては、上記実施形態では傾斜する前後方向に沿って4枚の太陽光発電パネルPが配置する構成を例示したが、前後方向の該発電パネルPの配置枚数と全体幅には特に制約はない。しかして、据付装置における前後(傾斜)方向に沿う垂直支柱2の本数は、太陽電池アレイ10の前後方向の全体幅の広狭によって増減することになる。また、太陽電池アレイ10の左右方向の長さについては、敷地の広さと発電システムの規模及びレイアウトによる制約のみである。一方、太陽電池アレイ10の傾斜角度についても、据付場所の緯度に応じて年間平均で受光効率が最も高くなる角度とすればよく、赤道直下での0°から極地での90°まで任意に設定できる。因みに、太陽光発電パネルPの傾斜方向幅が1m程度である場合の、太陽電池アレイの全体幅と傾斜角度及び設置高さの違いによる据付装置の構成例を図10〜図12に示す。   As the solar cell array 10 to which the present invention is applied, the configuration in which the four photovoltaic power generation panels P are arranged along the inclined front-rear direction in the above embodiment is exemplified. However, the number of the power generation panels P arranged in the front-rear direction is exemplified. There is no particular restriction on the overall width. Therefore, the number of the vertical support | pillars 2 along the front-back (inclination) direction in an installation apparatus will increase / decrease with the breadth of the whole width | variety of the front-back direction of the solar cell array 10. FIG. Moreover, about the length of the solar cell array 10 in the left-right direction, there are only restrictions due to the size of the site, the scale of the power generation system, and the layout. On the other hand, the inclination angle of the solar cell array 10 may be set to an angle at which the light receiving efficiency becomes the highest on an average annually according to the latitude of the installation location, and is arbitrarily set from 0 ° immediately below the equator to 90 ° in the polar region. it can. Incidentally, FIG. 10 to FIG. 12 show configuration examples of the installation device depending on differences in the overall width, inclination angle, and installation height of the solar cell array when the inclination width of the photovoltaic power generation panel P is about 1 m.

まず、図10(a)の据付装置では、傾斜方向に2枚の太陽光発電パネルPが配置した全体幅の狭い太陽電池アレイ10Aを高位に設置するために、高くなった前後2本の垂直支柱2,2間に上下2本の補強桟16,16を架設すると共に、架台フレーム1の中間部と両垂直支柱2の根元部との間にブレース3,3を逆V字形に架設し、更に架台フレーム1の中間部と高い後部側の垂直支柱2の中間部との間にもブレース3を架設することで、架台構体としての全体強度を確保している。また、図10(b)の据付装置では、同様の太陽電池アレイ10Aを低位に設置するため、前後2本の垂直支柱2,2の根元部間に1本の補強桟16を架設し、架台フレーム1の中間部と両垂直支柱2の根元部との間にブレース3,3を逆V字形に架設することで、架台構体としての全体強度を確保できる。しかるに、図の実線と仮想線で示すように、太陽電池アレイ10Bの傾斜角度によってブレース3,3の逆V字形の開き角度が変わると共に、該傾斜角度が低く前後方向に長くなる場合は前後の垂直支柱2,2間の距離を拡げることになる。   First, in the installation apparatus of FIG. 10 (a), in order to install a solar cell array 10A having a narrow overall width in which two photovoltaic power generation panels P are arranged in an inclined direction at a high level, two vertical front and rear elevations are provided. Two upper and lower reinforcing bars 16 and 16 are installed between the columns 2 and 2, and braces 3 and 3 are installed in an inverted V shape between the middle part of the gantry frame 1 and the bases of the two vertical columns 2; Furthermore, the brace 3 is installed between the middle part of the gantry frame 1 and the middle part of the vertical column 2 on the high rear side, thereby ensuring the overall strength of the gantry structure. Further, in the installation apparatus of FIG. 10 (b), in order to install the similar solar cell array 10A at a low level, one reinforcing bar 16 is installed between the root portions of the two front and rear vertical columns 2, 2, By bracing the braces 3 and 3 in an inverted V shape between the middle portion of the frame 1 and the base portions of the two vertical struts 2, the overall strength of the gantry structure can be ensured. However, as shown by the solid line and the virtual line in the figure, the opening angle of the inverted V shape of the braces 3 and 3 changes depending on the inclination angle of the solar cell array 10B, and when the inclination angle is low and long in the front-rear direction, The distance between the vertical supports 2 and 2 will be increased.

図11(a)の据付装置では、傾斜方向に3枚の太陽光発電パネルPが配置した前後幅のやや広い太陽電池アレイ10Bを高位に設置するが、前記の太陽電池アレイ10Aの場合と同様に、前後2本の垂直支柱2,2間に上下2本の補強桟16,16を架設し、ブレース3を架台フレーム1の中間部と両垂直支柱2の根元部との間ならびに架台フレーム1の中間部と後部側の垂直支柱2の中間部との間に架設することで、架台構体としての全体強度を確保している。また、図11(b)の据付装置では、同様の太陽電池アレイ10Bを低位に設置するが、やはり前記の太陽電池アレイ10Aの場合と同様に、前後の垂直支柱2,2の根元部間に1本の補強桟16を架設し、架台フレーム1の中間部と両垂直支柱2の根元部との間にブレース3,3を逆V字形に架設することで、架台構体としての全体強度を確保しており、太陽電池アレイ10Bの傾斜角度によってブレース3,3の逆V字形の開き角度が変わることと、該傾斜角度が低い場合に前後の垂直支柱2,2間の距離を拡げることも同様である。   In the installation apparatus of FIG. 11A, the solar cell array 10B having a slightly wider front and rear width in which the three photovoltaic power generation panels P are arranged in the inclination direction is installed at a high level, but is the same as in the case of the solar cell array 10A. Further, two upper and lower reinforcing bars 16, 16 are installed between the two front and rear vertical struts 2, 2, and the brace 3 is placed between the middle part of the base frame 1 and the base part of the two vertical struts 2 and the base frame 1. The overall strength of the gantry structure is ensured by erection between the middle part of the vertical column and the middle part of the vertical column 2 on the rear side. Further, in the installation apparatus of FIG. 11B, the similar solar cell array 10B is installed at a low position, but, similarly to the case of the solar cell array 10A, between the root portions of the front and rear vertical columns 2, 2. One reinforcing bar 16 is installed, and braces 3 and 3 are installed in an inverted V shape between the middle part of the gantry frame 1 and the base parts of the two vertical columns 2, thereby ensuring the overall strength of the gantry structure. The opening angle of the inverted V-shaped braces 3 and 3 changes depending on the inclination angle of the solar cell array 10B, and the distance between the front and rear vertical columns 2 and 2 can be increased when the inclination angle is low. It is.

図12のの据付装置では、傾斜方向に4枚の太陽光発電パネルPが配置した前後幅の広い太陽電池アレイ10Cを設置するため、前後部と中間部の3本の垂直支柱2を用いると共に、前部と中間部の垂直支柱2,2の根元部と架台フレーム1との間、ならびに中間部と後部の垂直支柱2,2の根元部と架台フレーム1との間に、それぞれブレース3,3を逆V字形に架設し、また前後部と中間部の3本の垂直支柱2にわたって根元部間に補強桟16を架設することにより、架台構体としての全体強度を確保している。この場合、太陽電池アレイ10Cが大サイズで、その傾斜角度の違いによる前後方向の長さの変化が大きいため、前部の垂直支柱2に対して中間及び後部の垂直支柱2,2の位置が該傾斜角度が低いほど後方へ移動している。   In the installation apparatus of FIG. 12, in order to install a solar cell array 10C having a wide front-rear width in which four photovoltaic power generation panels P are arranged in an inclination direction, three vertical columns 2 of the front-rear part and the middle part are used. The braces 3, respectively, are arranged between the base of the vertical struts 2, 2 at the front and the middle and the gantry frame 1, and between the base of the vertical struts 2, 2 at the rear and the pedestal frame 1, respectively. 3 is installed in an inverted V-shape, and a reinforcing bar 16 is installed between the root portions over the three vertical columns 2 at the front and rear and the middle, thereby ensuring the overall strength of the gantry structure. In this case, since the solar cell array 10C is large in size and the change in the length in the front-rear direction due to the difference in inclination angle is large, the positions of the middle and rear vertical struts 2, 2 with respect to the front vertical strut 2 are The lower the angle of inclination, the more it moves backward.

なお、実施形態では太陽電池アレイ1の太陽光発電パネルPが横長であるために、該太陽電池アレイ1を架台フレーム1の縦桟11で支承しているが、太陽光発電パネルPが縦長の場合は該太陽電池アレイ1を架台フレーム1の横桟12で支承することになる。また、ブレース取付桟13は、実施形態では架台フレーム1の縦桟11,11間に左右方向に沿う形で架設しているが、該架台フレーム1の横桟12,12間に前後方向に沿う形で架設してもよい。また、実施形態では各垂直支柱2をスクリュー杭8上に立設しているが、スクリュー杭8に代えてPC杭の如きコンクリート杭を用いてもよく、更に陸屋根のような杭打ち不能な据付場所ではコンクリート製の土台上に垂直支柱2を立設すればよい。   In the embodiment, since the solar power generation panel P of the solar cell array 1 is horizontally long, the solar cell array 1 is supported by the vertical rail 11 of the gantry frame 1, but the solar power generation panel P is vertically long. In this case, the solar cell array 1 is supported by the horizontal rail 12 of the gantry frame 1. In the embodiment, the brace mounting bar 13 is installed between the vertical bars 11 and 11 of the gantry frame 1 along the left-right direction. However, the brace mounting bar 13 extends between the horizontal bars 12 and 12 of the gantry frame 1 along the front-rear direction. You may build in the form. Further, in the embodiment, each vertical support 2 is erected on the screw pile 8, but a concrete pile such as a PC pile may be used instead of the screw pile 8, and a non-pileable installation such as a flat roof is possible. At the place, the vertical support 2 may be erected on a concrete base.

本発明による太陽電池アレイの据付装置では、前後及び左右に隣接した4本の垂直支柱2位置を頂点とする矩形内におけるブレース3の配置本数及び配置間隔と、各ブレース3の傾斜角度は、実施形態による例示構成に限らず、該矩形単位のサイズや架台フレーム1の傾斜角度等に応じて種々設定可能である。しかして、ブレース3によるトラス構造の架台構体として、例えば図13に示すように、架台フレーム1に対して各ブレース3の上端側を垂直支柱2の上端近傍でブレース取付桟(図示省略)に止着すると共に、その下端側を前後に隣接する垂直支柱2,2の中間位置で土台17上に適当な取付手段を介して止着することにより、前後に隣接する垂直支柱2,2間に2本のブレース3,3が既述の実施形態とは逆にV字形をなすように配設する構成も採用可能である。ただし、この場合には、トラス構造によって架台構体としての強度は増すが、ブレース3による架台フレーム1の支承位置が前記矩形内の中央寄りにならないため、該矩形のサイズが大きい場合にその中央側での架台フレーム1の撓み変形を生じ易くなる。   In the solar cell array installation apparatus according to the present invention, the number of braces 3 placed and the spacing between the four vertical struts 2 adjacent to the front and rear and right and left, and the inclination angle of each brace 3 are Not limited to the exemplary configuration according to the form, various settings can be made according to the size of the rectangular unit, the inclination angle of the gantry frame 1 and the like. As shown in FIG. 13, for example, as shown in FIG. 13, the upper end side of each brace 3 is fixed to a brace mounting bar (not shown) in the vicinity of the upper end of the vertical column 2 as the frame structure of the truss structure by the brace 3. At the same time, the lower end side is fixed on the base 17 at an intermediate position between the vertical struts 2 and 2 adjacent to each other by an appropriate attachment means, so that 2 A configuration in which the braces 3 and 3 of the book are arranged so as to form a V shape contrary to the above-described embodiment can also be adopted. However, in this case, although the strength as the gantry structure is increased by the truss structure, the support position of the gantry frame 1 by the brace 3 is not close to the center in the rectangle, so that the center side when the size of the rectangle is large It becomes easy to produce the bending deformation of the mount frame 1 at.

更に、本発明においては、止着金具4、ブラケット5A,5B、結合金具6、連結金具7の形態とこれらの取付構造、太陽電池アレイ10の架台フレーム1に対する取付構造、架台フレーム1の縦桟11及び横桟12、ブレース取付桟13、胴桟14、垂直支柱2、ブレース3に用いる中空アルミ型材の断面形状等、細部構成については実施形態以外に種々設計変更可能である。   Furthermore, in the present invention, the form of the fixing metal fittings 4, brackets 5A and 5B, coupling metal fittings 6 and connecting metal fittings 7 and their attachment structures, the attachment structure of the solar cell array 10 to the frame frame 1, the vertical beam of the frame frame 1 11 and various configurations other than the embodiment can be changed in detail, such as a cross-sectional shape of a hollow aluminum mold member used for the horizontal rail 12, the brace mounting rail 13, the trunk rail 14, the vertical column 2, and the brace 3.
