Description

本発明は、建築物の屋根面にソーラー発電装置を設置する際に用いる、太陽電池モジュールの取付構造に関する。   The present invention relates to a solar cell module mounting structure used when a solar power generation device is installed on a roof surface of a building.
ソーラー発電は、環境負荷が小さく資源を節約できるため、地球温暖化の基となるCO2 (二酸化炭素)を含む排出ガスによる環境汚染、エネルギー資源の枯渇など地球的規模の課題対策として開発が進み、商業ビル、公共施設を始めとして一般家庭へも普及している。   Since solar power generation has a low environmental impact and can conserve resources, development has progressed as a countermeasure for global issues such as environmental pollution by exhaust gas containing CO2 (carbon dioxide), which is the basis of global warming, and depletion of energy resources. It is also widely used in commercial buildings and public facilities as well as ordinary households.
ところで、瓦等の屋根材はその上に物を設置することを考慮することなく設計、製造されたものである。従って戸建て住宅等において前記屋根材の上に太陽電池モジュールを設置する場合は、屋根面が緩急様々な勾配を持つとともに完全な雨仕舞が要求されるなどの諸条件も加わって、複雑な構造により太陽電池モジュールが支持され、施工性も劣りがちである。そこでこれに対し改良が重ねられ、様々な取付構造が提案されている(例えば、特許文献1参照)。   By the way, roof materials such as tiles are designed and manufactured without considering the installation of objects on them. Therefore, when installing a solar cell module on the roof material in a detached house, etc., it has a complicated structure, including various conditions such as the roof surface having various slopes and a complete rain finish. Solar cell modules are supported and workability tends to be inferior. Thus, improvements have been made repeatedly, and various mounting structures have been proposed (see, for example, Patent Document 1).
その一つとして図9、10に示される取付構造では、先ず図9(A)に示すように、屋根材aに上から電気ドリルbを用いて貫通孔dを穿設し、次いで図9(B)に示すように、防水性維持のため、前記貫通孔d内にブチルゴム等の水密材nを充填し、図9(C)に示すように、その上から挿入するとともに屋根下地板fに打ち込んでビスe1により、縦レールgを固定している。   As one example, in the mounting structure shown in FIGS. 9 and 10, first, as shown in FIG. 9 (A), a through hole d is drilled in the roof material a from above using an electric drill b, and then FIG. As shown in FIG. 9B, in order to maintain waterproofness, the through hole d is filled with a watertight material n such as butyl rubber, and is inserted from above as shown in FIG. The vertical rail g is fixed with a screw e1.
また図11に示される取付構造では、屋根材aの一部(a1)を一旦取外し、露出した屋根下地板f上にベース合板i及びスペース合板jが、屋根下地板fを貫通し垂木kに打ち込まれたビスe2により固着される。そして基板m1と、この基板m1の軒先側端縁から立ち上がる縦片m2と、この縦片m2の上端から軒先側に向け伸びる上片m3とが一体に折り曲げ形成されたZ字状金具mの前記基板m1の棟側をビスe3によりスペース合板j上に固着するとともに上片m3に縦レールgが取付けられる。そして前記取外された屋根材a1が元の位置の戻されて取付部が雨仕舞される。   Further, in the mounting structure shown in FIG. 11, a part (a1) of the roof material a is once removed, and the base plywood i and the space plywood j penetrate the roof baseboard f into the rafter k through the exposed roof baseboard f. It is fixed by the driven screw e2. The Z-shaped metal fitting m in which the substrate m1, the vertical piece m2 rising from the edge of the eaves side of the substrate m1, and the upper piece m3 extending from the upper end of the vertical piece m2 toward the eaves side are bent together. The ridge side of the substrate m1 is fixed on the space plywood j with the screw e3, and the vertical rail g is attached to the upper piece m3. Then, the removed roof material a1 is returned to its original position, and the attachment portion is rained.
特開2004−162487号公報JP 2004-162487 A
しかしながら図9、10に示される前者の取付構造においては、屋根材a上に載置される縦レールgを介して太陽電池モジュールhの荷重が屋根材aに負荷するため、台風などの強風下大きな応力が発生する時屋根材aに割れ、欠けを生じ易く、太陽電池モジュールhの支持が不安定であるとともに雨漏りの恐れがある。特に既設建物の屋根にリフォームによって太陽光発電設備を設置する場合は屋根材aが経年劣化により強度低下していることも多く、雨仕舞を損なう可能性が高い。   However, in the former mounting structure shown in FIGS. 9 and 10, since the load of the solar cell module h is applied to the roof material a through the vertical rail g placed on the roof material a, it is under a strong wind such as a typhoon. When a large stress is generated, the roof material a is likely to be cracked or chipped, the support of the solar cell module h is unstable, and there is a risk of rain leakage. In particular, when installing a photovoltaic power generation facility by renovation on the roof of an existing building, the roof material a is often reduced in strength due to deterioration over time, and there is a high possibility of impairing the rain performance.
また本工法は図9(C)に示すように、穿設された貫通孔dに充填された水密材nにビスe1を挿入するとともに屋根下地板fに打ち込んで縦レールgを取付けるため、取付後における水密材nによる止水状態を目視で確認することができず、ビスe1の挿入時に水密材nが貫通孔dから離脱する可能性もあり、雨仕舞の信頼性が低い。   In addition, as shown in FIG. 9C, this construction method inserts the screw e1 into the watertight material n filled in the drilled through hole d and drives it into the roof base plate f to attach the vertical rail g. The water-stopping state due to the water-tight material n later cannot be visually confirmed, and the water-tight material n may be detached from the through-hole d when the screw e1 is inserted, and the reliability of the rain performance is low.
さらに、屋根材aに穿設された貫通孔dの径はビスe1よりやや大きい程度であるため、この貫通孔dを通して屋根下地板fの厚さ、材質、経年劣化の程度等の状況を目視確認することはできない。従ってリフォームにおいて、ビスe1の固定強度が判定できないため、予測に基づいて多めに固定せざるを得ず、信頼性を欠くとともに施工性が低下する。   Furthermore, since the diameter of the through hole d drilled in the roof material a is slightly larger than the screw e1, the state of the thickness, material, degree of deterioration, etc. of the roof base plate f is visually observed through the through hole d. It cannot be confirmed. Accordingly, in the renovation, the fixing strength of the screw e1 cannot be determined. Therefore, it is necessary to fix the screw e1 in a large amount on the basis of the prediction.
また図11に示される後者の取付構造においては、勾配方向上下に隣接する屋根材aの重なり部から延出しうるZ字状金具mを介して、縦レールgを屋根下地板fに取付けているため、基板m1の棟側でビスe3により屋根下地板fに固着された位置に対し、勾配下方に大きくズレた位置において縦レールgが上片m3により支持されている。したがって、太陽電池モジュールhに対して風荷重による正負の動圧が作用したとき、Z字状金具mに曲げ力の作用により変形し、太陽電池モジュールhの支持が不安定な状態となる。   In the latter mounting structure shown in FIG. 11, the vertical rail g is attached to the roof base plate f via the Z-shaped metal fitting m that can extend from the overlapping portion of the roof material a adjacent in the gradient direction. Therefore, the vertical rail g is supported by the upper piece m3 at a position greatly deviated downward from the position fixed to the roof base plate f by the screw e3 on the ridge side of the substrate m1. Therefore, when positive and negative dynamic pressure due to wind load acts on the solar cell module h, the Z-shaped metal fitting m is deformed by the action of bending force, and the support of the solar cell module h becomes unstable.
また本発明の実施態様の課題として、ビスe2を垂木kに対して打ち込んで固定する場合、ルーフィングシートが敷設されていることもあり垂木kの位置は屋根下地板f上からでは不明なため、垂木を外しがちとなりその時には取付強度が不足する。   In addition, as a problem of the embodiment of the present invention, when the screw e2 is driven and fixed to the rafter k, the roofing sheet may be laid and the position of the rafter k is unknown from the roof base plate f. The rafter tends to be removed, and the mounting strength is insufficient.
本発明は、取付具は、屋根材に形成された切欠部に挿入されるとともに屋根下地板の上に載置した状態で固着されることを基本とし、支持構造がシンプルで太陽電池モジュールを安定して取付できるとともに施工性に優れる太陽電池モジュールの取付構造の提供を課題としている。   The present invention is based on the fact that the fixture is inserted into a notch formed in the roof material and fixed in a state of being placed on the roof base plate, and the support structure is simple and the solar cell module is stabilized. Therefore, it is an object to provide a solar cell module mounting structure that can be mounted and has excellent workability.
前記目的を達成するために、請求項1に係る発明は、屋根下地板に屋根材を敷設して構成された屋根の上に配設される複数の太陽電池モジュールと、この太陽電池モジュールを支持する支持体と、この支持体を屋根に取付ける取付具とを具え、前記屋根材には、貫通した切欠部が形成され、前記取付具は、前記切欠部に挿入されるとともに前記屋根下地板の上に載置した状態で固着され、かつ前記支持体を取付けるための上に向く固定ボルトを有する固定金具からなり、前記切欠部及び前記固定金具を覆って水密する被覆カバーを設けたことを特徴とする。   In order to achieve the object, the invention according to claim 1 supports a plurality of solar cell modules disposed on a roof constructed by laying a roof material on a roof base plate, and supports the solar cell modules. A support for attaching the support to the roof, and the roof material is formed with a notch that penetrates, and the attachment is inserted into the notch and the roof base plate A fixing bracket that is fixed in a state where it is placed on top and that has a fixing bolt facing upward for mounting the support is provided, and a covering cover that covers the notch and the fixing bracket and is watertight is provided. And
請求項2に係る発明では、前記固定金具は、下に向け開口するコ字体と、このコ字体の向き合う縦片下端から各々外側に折れ曲って伸びる取付フランジとを具えてハット状をなし、前記被覆カバーは、カバー本体とこのカバー本体の上に重ねて配されるキャップとからなり、前記カバー本体は、前記固定金具の上方を囲むシェル部と、このシェル部の周縁部から周囲に向け屋根面に沿って伸びる鍔部とからなるとともに前記キャップは、カバー本体のシェル部に上方から嵌合することを特徴とする。   In the invention according to claim 2, the fixing bracket comprises a U-shaped opening that opens downward, and a mounting flange that extends and bends outward from the lower end of each vertical piece facing the U-shaped, The covering cover includes a cover main body and a cap arranged on the cover main body. The cover main body includes a shell portion that surrounds the fixing bracket, and a roof that extends from the peripheral edge portion of the shell portion to the periphery. The cap includes a flange extending along the surface, and the cap is fitted to the shell portion of the cover body from above.
請求項3に係る発明では、前記取付具は、拡開固着具を用いて屋根下地板に固着され、前記拡開固着具は、屋根下地板に穿設される取付孔に挿通される挿通部と、この挿通部の下端に形成され、かつ前記取付孔に上側から挿入されるとともに屋根下地板の下側で拡開して屋根下地板に係合する抜け止め部とを含み、前記抜け止め部と屋根下地板との係合を利用して、取付具を屋根下地板に固着することを特徴とする。   In the invention which concerns on Claim 3, the said fixture is fixed to a roof baseplate using an expansion sticker, and the said expansion sticker is penetrated by the attachment hole drilled in a roof baseplate. And a retaining portion that is formed at the lower end of the insertion portion and is inserted into the mounting hole from above and that expands below the roof base plate and engages the roof base plate. The fixture is fixed to the roof base plate using the engagement between the portion and the roof base plate.
請求項1に係る発明は、取付具は屋根材に形成した切欠部に挿入して屋根下地に固着されるため、太陽電池モジュールの荷重は取付具を介して略直下の屋根下地により支持される。その結果支持構造がシンプル化されるとともに太陽電池モジュールの取付強度が安定し、台風など強風下においても確実に支持されるとともに施工性に優れる。また太陽電池モジュールの荷重が屋根材に掛からないため、屋根材の破損が防止され、既設建物に対してリフォームにより取付施工する場合に屋根材が経年劣化していても、雨漏れの恐れがない。さらに前記リフォームにおいて、切欠部を介して屋根下地板の劣化状態を目視確認できるため、状況に対応した施工が可能となり信頼性を高めうる。また、固定ボルトを用いて支持体を強固に支持できるとともに被覆カバーにより精度の高い雨仕舞を構成できる。また請求項2に係る発明では、固定金具は取付フランジを用いて屋根下地板に強力に固定されるため、太陽電池モジュールの取付状態が安定し、カバー本体は屋根面に沿って伸びる鍔部を有するため、屋根面上に安定して取付けられるとともに、雨仕舞を良好とし、しかもカバー本体のシェル部にキャップが嵌合するため、雨仕舞の精度が更に向上する。   In the invention according to claim 1, since the fixture is inserted into the notch formed in the roof material and fixed to the roof base, the load of the solar cell module is supported by the roof base almost directly through the fixture. . As a result, the support structure is simplified, the mounting strength of the solar cell module is stabilized, the support structure is reliably supported even under strong winds such as typhoons, and the workability is excellent. In addition, since the load of the solar cell module is not applied to the roofing material, damage to the roofing material is prevented, and there is no risk of rain leakage even if the roofing material deteriorates over time when it is attached to an existing building by renovation. . Furthermore, in the renovation, since the deterioration state of the roof base plate can be visually confirmed through the notch, construction corresponding to the situation is possible, and reliability can be improved. In addition, the support body can be firmly supported by using the fixing bolt, and a highly accurate rain performance can be configured by the covering cover. Moreover, in the invention which concerns on Claim 2, since a fixing bracket is firmly fixed to a roof baseplate using an attachment flange, the attachment state of a solar cell module is stabilized, and a cover main body has a collar part extended along a roof surface. Therefore, it can be stably mounted on the roof surface, the rain performance is improved, and the cap is fitted to the shell portion of the cover body, so that the accuracy of the rain performance is further improved.
また請求項3に係る発明のように、拡開固着具を用いて取付具を屋根下地板に固着すると、リフォームの場合に屋根下地板が経年劣化していても、それを破損することなく安定した取付強度を得ることができ、さらに垂木の位置に関係なく取付具を固定できるため施工性が良い。   Further, as in the invention according to claim 3, when the fixture is fixed to the roof base plate using the spread fixing tool, even if the roof base plate has deteriorated over time in the case of renovation, it is stable without being damaged. Since the attachment strength can be obtained, and the fixture can be fixed regardless of the position of the rafter, the workability is good.
以下、本発明の実施の一形態を、図示例とともに説明する。図1に示すように、太陽電池モジュールの取付構造1は、屋根Rの上に配設される複数の太陽電池モジュールMと、この太陽電池モジュールMを支持する支持体4と、この支持体4を屋根Rに取付ける取付具5とを具える。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1, the solar cell module mounting structure 1 includes a plurality of solar cell modules M disposed on a roof R, a support 4 that supports the solar cell module M, and the support 4. Is attached to the roof R.
前記太陽電池モジュールMは、太陽光を電気エネルギーに変換する機能を持つ最小単位である太陽電池セルが複数接続され、さらにその表面に透明フィルム、透明樹脂、裏面に絶縁樹脂、補強材などを配した耐候性パッケージ内に納められて平板状に構成されるものである。その平面形状は通常矩形状とし、一辺が例えば500〜2000mm程度に形成されるが、設置箇所の状況に応じて三角形状、台形状などに形成されるものもある。そして太陽電池モジュールMは複数枚が屋根上に配設されるとともに直列、並列に接続されて、太陽電池アレイが構成される。   The solar cell module M is connected to a plurality of solar cells, which are the minimum unit having the function of converting sunlight into electric energy, and further, a transparent film, a transparent resin, an insulating resin, a reinforcing material, etc. are arranged on the front surface. It is housed in a weather-resistant package and configured in a flat plate shape. The planar shape is usually rectangular, and one side is formed, for example, in the range of about 500 to 2000 mm. However, there are some that are formed in a triangular shape, a trapezoidal shape, etc. depending on the situation of the installation location. A plurality of solar cell modules M are arranged on the roof and connected in series and in parallel to form a solar cell array.
前記太陽電池モジュールMを設置する屋根Rは、図1に示すように、屋根下地板2に屋根材3を敷設して構成される。そして本形態の屋根Rは、図1に示すように、矩形状をなす外周枠21a1と、この外周枠21a1の内側に架け渡された縦又は横の補強枠21a2とかなるパネルフレーム21aの上面に、屋根下地板(野地板)2を形成するパネル面材21bを貼着した屋根パネル21を用いて構成されたものが例示される。該屋根パネル21は桁側の壁パネル22の上枠22aにボックス金具23を介して固着され、下端部は鼻隠し板24で被覆されている。該鼻隠し板24は、その外側に、ブラケット25aを用いて軒樋25が取り付けられ、かつ前記桁側の壁パネル22との間に軒天井材26が架け渡されている。なおこの軒天井材26により、前記屋根パネル21の軒先下面が覆われて化粧される。   As shown in FIG. 1, the roof R on which the solar cell module M is installed is configured by laying a roof material 3 on a roof base plate 2. As shown in FIG. 1, the roof R of the present embodiment has a rectangular outer peripheral frame 21a1 and an upper surface of a panel frame 21a which is a vertical or horizontal reinforcing frame 21a2 spanned inside the outer peripheral frame 21a1. What was comprised using the roof panel 21 which affixed the panel surface material 21b which forms the roof base plate (field board) 2 is illustrated. The roof panel 21 is fixed to the upper frame 22 a of the wall panel 22 on the girder side via a box metal fitting 23, and the lower end portion is covered with a nose cover plate 24. On the outside of the nose cover plate 24, an eaves wall 25 is attached using a bracket 25 a, and an eaves ceiling material 26 is bridged between the wall panel 22 on the side of the girders. The eaves ceiling material 26 covers the underside of the eaves of the roof panel 21 for makeup.
前記屋根材3は、屋根防水のため屋根下地板2の上に敷設されたルーフィングシート27の上に配設され、個々の屋根材3は、略矩形の平板状をなし、軒先から棟方向に向かって、棟側の屋根材3の下端部を軒側の屋根材3の上端部に重ねながら隙間なく屋根下地板2に取り付けられる。屋根材3は、プレスセメント瓦、施釉セメント瓦、コンクリート瓦、いぶし瓦、金属瓦等各種のものを採用しうる。   The roofing material 3 is disposed on a roofing sheet 27 laid on the roof base plate 2 for waterproofing the roof, and each roofing material 3 has a substantially rectangular flat plate shape from the eaves to the ridge direction. On the other hand, the roof base plate 2 is attached to the roof base plate 2 without a gap while overlapping the lower end portion of the roof material 3 on the ridge side with the upper end portion of the roof material 3 on the eave side. The roofing material 3 may employ various types such as a press cement tile, a glazed cement tile, a concrete tile, an smoldering tile, and a metal tile.
前記屋根材3には、図3に示すように、切欠部6が形成される。本形態の切欠部6は円形をなし、太陽電池モジュールMの必要支持強度に基づき、割り付けられた所定のピッチで隔設される。またその直径は、例えば20〜80mm程度、本形態では40mmの大きさに形成され、電動ドリルに装着したホールソーを用いて切削形成することができる。このように形成された切欠部6を介して屋根材3の上から屋根下地板2の厚さ、材質、劣化状態などの状況を目視で確認し、その状況に応じて適宜太陽電池モジュールMの固定手段の選択、変更、補強処置などを適確に行ない、その結果太陽電池モジュール取付の信頼性が高めることができる。なお前記切欠部6は円形以外に、矩形、三角形、正五角形などとすることもできる。   As shown in FIG. 3, a notch 6 is formed in the roof material 3. The notches 6 in this embodiment are circular, and are spaced at a predetermined assigned pitch based on the required support strength of the solar cell module M. The diameter is, for example, about 20 to 80 mm, and in this embodiment, the size is 40 mm, and can be formed by cutting using a hole saw attached to an electric drill. The state of the thickness, material, and deterioration state of the roof base plate 2 is visually confirmed from the top of the roofing material 3 through the notch 6 formed in this way, and the solar cell module M is appropriately selected according to the state. Selection, change, and reinforcement of the fixing means are appropriately performed, and as a result, the reliability of the solar cell module mounting can be improved. In addition, the said notch part 6 can also be made into a rectangle, a triangle, a regular pentagon other than circular.
また本形態では、屋根下地板2の前記切欠部6の中央直下に、拡開固着具15を装着するための取付孔16が穿設される。この取付孔16は、直径が例えば10〜40mm程度、本形態では22mmの円孔に形成される。そして取付孔16は、電動ドリルに装着したドリルビット或いはホールソーを前記切欠部6内に挿入することにより穿設できる。   Further, in this embodiment, a mounting hole 16 for mounting the spread fixing tool 15 is drilled immediately below the center of the notch 6 of the roof base plate 2. The mounting hole 16 is formed in a circular hole having a diameter of about 10 to 40 mm, for example, and 22 mm in this embodiment. The mounting hole 16 can be drilled by inserting a drill bit or a hole saw attached to the electric drill into the notch 6.
前記取付孔16に装着する拡開固着具15は、図2、3に示すように、挿通部17と、抜け止め部18とからなる。挿通部17は、下端外周にネジ28が螺刻された円筒体17Aと、この円筒体17Aの上端全周から外側へ伸びる鍔体17Bとからなる。該鍔体17Bは挿通部17よりも大きな直径を有し、円筒体17Aが上から挿入された時、取付孔16の上縁部に係合して挿通部17を支持できるように形成される。但し鍔体17Bは、前記切欠部6内を通過しうるよう、切欠部6よりも小径に形成される。   As shown in FIGS. 2 and 3, the expanding and fixing tool 15 attached to the mounting hole 16 includes an insertion portion 17 and a retaining portion 18. The insertion portion 17 includes a cylindrical body 17A in which a screw 28 is threaded on the outer periphery of the lower end and a housing 17B extending outward from the entire upper end of the cylindrical body 17A. The housing 17B has a diameter larger than that of the insertion portion 17, and is formed so that the insertion portion 17 can be supported by engaging with the upper edge portion of the mounting hole 16 when the cylindrical body 17A is inserted from above. . However, the housing 17 </ b> B is formed to have a smaller diameter than the notch 6 so as to pass through the notch 6.
前記抜け止め部18は、上下に貫通するネジ孔29を有するナット状体18Aと、このナット状体18Aの外周に、上向きと外向きとの間で起倒可能に軸着され、放射状に隔設された複数、本形態では6本の係止脚18Bとからなる。またナット状体18Aの上面には、内周面にネジ30が螺刻された凹部40を有する。   The retaining portion 18 is attached to a nut-like body 18A having a screw hole 29 penetrating vertically and to the outer periphery of the nut-like body 18A so that it can be tilted between upward and outward, and radially separated. It consists of a plurality of provided, in this embodiment, six locking legs 18B. Further, the upper surface of the nut-like body 18A has a recess 40 in which a screw 30 is screwed on the inner peripheral surface.
前記拡開固着具15を取付孔16に取付けるに際し図3に示すように、下端を前記抜け止め部18のネジ孔29に螺合したネジ棒31の上部を把持して、抜け止め部18を取付孔16に上から挿入する。抜け止め部18の係止脚18Bは、この挿入時に取付孔16の内周にガイドされ上向きの姿勢でネジ棒31に沿うため、取付孔16をスムースに通過できる。しかし取付孔16を通過した後は、係止脚18Bは自重により先端が外側へ倒れて、取付孔16の下方縁部に係合するため、抜け止め部18は再び取付孔16から屋根下地板2の上に抜け出すことができくなる。ネジ棒31を引き上げることにより抜け止め部18を取付孔16周縁の屋根下地板2下面に密着係合させ、この状態で前記ネジ棒31を挿入して下方へスライドさせた挿通部17のネジ28を、抜け止め部18のネジ30に螺合することにより挿通部17の鍔体17Bと抜け止め部18の係止脚18Bとで屋根下地板2の取付孔16周縁を挟着し、これにより拡開固着具15が屋根下地板2に固定される。なおこの時、屋根下地板2の取付孔16周縁下面と係止脚18Bとの間にドーナッツ板状のゴムパッキン32を挿入することにより、前記拡開固着具15の空転が防止されるため、拡開固着具15をより安定して固定できる。   As shown in FIG. 3, when attaching the expanding and fixing tool 15 to the attachment hole 16, the lower end is gripped by the upper part of the screw rod 31 screwed into the screw hole 29 of the retaining part 18, so that the retaining part 18 is secured. Insert into the mounting hole 16 from above. Since the locking leg 18B of the retaining portion 18 is guided by the inner periphery of the mounting hole 16 and is along the screw rod 31 in an upward posture at the time of insertion, the mounting leg 16 can pass smoothly. However, after passing through the mounting hole 16, the locking leg 18 </ b> B falls to the outside due to its own weight and engages with the lower edge of the mounting hole 16. It becomes impossible to get out over 2. By pulling up the screw rod 31, the retaining portion 18 is brought into close contact with the lower surface of the roof base plate 2 at the periphery of the mounting hole 16, and the screw 28 of the insertion portion 17 is inserted and slid downward in this state.

そして、前記ベース板8Aの通孔33に挿入されたボルト36を前記拡開固着具15のネジ孔29に螺装することにより、固定片8B、8Bが前記屋根材3の切欠部6に挿入された状態で固定部8が屋根下地板2に固着される。この時本形態では、固定部8と拡開固着具15との間にパッキン55が介装されるため、屋根下地板2の取付孔16の水密性が確保される点で好ましい。さらに、ベース板8Aの前記切欠き34に係合したビス54を拡開固着具15に打ち込むことにより固定部8が廻り止めされる。このように本形態では、取付具5を構成するパーツとして分離して形成された固定部8を用いて、屋根下地板2への固着を行うため、小さな切欠部6を通しての固着作業を簡単に行うことができる。   Then, the fixing pieces 8B and 8B are inserted into the notches 6 of the roof material 3 by screwing the bolts 36 inserted into the through holes 33 of the base plate 8A into the screw holes 29 of the expanding and fixing tool 15. In this state, the fixing portion 8 is fixed to the roof base plate 2. At this time, in this embodiment, since the packing 55 is interposed between the fixing portion 8 and the spread fixture 15, it is preferable in that the water tightness of the mounting hole 16 of the roof base plate 2 is ensured. Further, the fixed portion 8 is prevented from rotating by driving a screw 54 engaged with the notch 34 of the base plate 8 </ b> A into the expansion fixture 15. As described above, in the present embodiment, the fixing portion 8 formed separately as parts constituting the fixture 5 is used to fix the roof base plate 2, so that the fixing work through the small notch portion 6 can be easily performed. It can be carried out.
前記筒部7を上から切欠部6内に挿入するとともに、その下部を前記屋根下地板2に固着された固定部8の固定片8B、8Bに外嵌する。更に上板9Aが筒部7の上端に当接する迄前記装着部9の固定脚片9B、9Bを筒部7の内部に挿入し、これにより前記固定脚片9B、9Bを固定部の固定片8B、8Bの内側に嵌合させる。そして筒部7、固定片8A及び固定脚片9Bを連続して貫通するビス37により筒部7と、固定部8と、装着部9とを一体化させ、これにより取付具5の全体が屋根下地板2に固着される。このとき、筒部7と屋根材3の切欠部6との間の小間隙に、シーリング材38を充填して防水性を確保する。このシール作業は充填状況を屋根上から作業者がはっきりと目視で確認できるため、信頼性が高い点で好ましい。   The cylindrical portion 7 is inserted into the cutout portion 6 from above, and the lower portion thereof is externally fitted to the fixing pieces 8B and 8B of the fixing portion 8 fixed to the roof base plate 2. Further, the fixed leg pieces 9B and 9B of the mounting portion 9 are inserted into the cylindrical portion 7 until the upper plate 9A comes into contact with the upper end of the cylindrical portion 7, whereby the fixed leg pieces 9B and 9B are inserted into the fixed pieces of the fixed portion. 8B and 8B are fitted inside. And the cylinder part 7, the fixing | fixed part 8, and the attachment part 9 are integrated by the screw | thread 37 which penetrates the cylinder part 7, the fixed piece 8A, and the fixed leg piece 9B continuously, Thereby, the whole fixture 5 is roof. Fixed to the base plate 2. At this time, a sealing material 38 is filled in a small gap between the cylindrical portion 7 and the cutout portion 6 of the roof material 3 to ensure waterproofness. This sealing operation is preferable in terms of high reliability because the operator can clearly check the filling state from the roof.
また、本形態では、図2、4に示すように、取付具5の屋根勾配上側を覆う水よけカバー39を取り付ける。この水よけカバー39は、切欠部6の両側方から屋根勾配上側を連続的に覆うカバー基板39Aと、このカバー基板39Aから立ち上がり、取付具5を囲むU字状のカラー39Bとからなり、前記ビス37がカラー39Bを貫通することにより、取付具5に固定される。図2に示すように、カバー基板39Aの屋根勾配上端部は、切欠部6を設けた屋根材3と、その勾配上に配される屋根材3との間に挿入される。このように、本形態では屋根材3を貫通する取付具5の勾配上側を水よけカバー39が覆うため、雨仕舞が良好となる点で好ましい。   In this embodiment, as shown in FIGS. 2 and 4, a water shielding cover 39 that covers the roof slope upper side of the fixture 5 is attached. This water-proof cover 39 is composed of a cover substrate 39A that continuously covers the upper side of the roof slope from both sides of the notch 6, and a U-shaped collar 39B that rises from the cover substrate 39A and surrounds the fixture 5. The screw 37 is fixed to the fixture 5 by passing through the collar 39B. As shown in FIG. 2, the upper end portion of the roof gradient of the cover substrate 39A is inserted between the roof material 3 provided with the notch 6 and the roof material 3 arranged on the gradient. Thus, in this form, since the water shielding cover 39 covers the gradient upper side of the fixture 5 which penetrates the roofing material 3, it is preferable at the point from which a rain finish becomes favorable.
前記支持体4は、本形態では図1に示すように、屋根勾配方向の縦レール4Aと、屋根勾配方向に間隔を隔てて配設される横レール4Bとからなる。前記縦レール4Aはその下部フランジ4A1を貫通する前記装着部9の装着ボルト35にナット41を螺装して締め付けることにより、上下端を含む複数箇所で取付具5を介して屋根Rに取り付けられる。そして、前記縦レール4Aの上部フランジ4A2に前記横レール4Bが載置されるとともに固着具42により固着され、これにより縦レール4Aと横レール4Bとで格子状をなす支持体4が屋根Rに取付られる。   As shown in FIG. 1, the support 4 is composed of a vertical rail 4 </ b> A in the roof gradient direction and a horizontal rail 4 </ b> B disposed at an interval in the roof gradient direction in this embodiment. The vertical rail 4A is attached to the roof R via the fixtures 5 at a plurality of locations including the upper and lower ends by screwing and tightening nuts 41 to the mounting bolts 35 of the mounting portion 9 passing through the lower flange 4A1. . Then, the horizontal rail 4B is placed on the upper flange 4A2 of the vertical rail 4A and fixed by the fixing tool 42, whereby the support body 4 having a lattice shape with the vertical rail 4A and the horizontal rail 4B is attached to the roof R. Attached.
前記横レール4Bの上に、太陽電池モジュールMの上下端が、専用金具43を用いて取り付けられる。このように太陽電池モジュールMを支持する取付具5は屋根材3に形成された切欠部6に挿入されるとともに屋根下地板2に固着され、従って太陽電池モジュールMの荷重は取付具5を介して略直下位置の屋根下地板2に支持される。その結果支持構造がシンプル化されるとともに太陽電池モジュールMの取付強度が安定し、台風など強風下においても確実に支持されるとともに施工性に優れる。しかも、太陽電池モジュールMの荷重が直接屋根材3に掛からないため、屋根材3を破損する恐れがない。特に既設建物に対しリフォームで取付ける場合、屋根材3が経年劣化していても雨漏れすることがない。   On the horizontal rail 4B, the upper and lower ends of the solar cell module M are attached using a dedicated metal fitting 43. Thus, the fixture 5 that supports the solar cell module M is inserted into the notch 6 formed in the roofing material 3 and fixed to the roof base plate 2, so that the load of the solar cell module M is passed through the fixture 5. And is supported by the roof base plate 2 located almost immediately below. As a result, the support structure is simplified, the mounting strength of the solar cell module M is stabilized, and the solar cell module M is reliably supported even in strong winds such as typhoons and is excellent in workability. And since the load of the solar cell module M is not directly applied to the roofing material 3, there is no possibility that the roofing material 3 will be damaged. In particular, when renovating the existing building, rain does not leak even if the roofing material 3 has deteriorated over time.
しかも本形態では、屋根下地板2とその下側の抜け止め部18との係合を利用して取付具5が屋根下地板2に固着され、しかも前記係合する範囲は抜け止め部18が拡開するため広い面積に拡がり、リフォーム施工の際、屋根下地板2が劣化により強度を低下している場合においても、応力が分散して屋根下地板2に破損を生じることなく安定した取付強度がえられる点で好ましい。しかも垂木に固着具を打ち込んで固定する場合のように垂木の配置位置を確認し、かつ垂木の位置に制約されることがないため作業性に優れる。   In addition, in this embodiment, the fixture 5 is fixed to the roof base plate 2 using the engagement between the roof base plate 2 and the retaining portion 18 below the roof base plate 2, and the retaining portion 18 is in the engaged range. Because it expands, it spreads over a wide area, and when renovation is performed, even if the roof base plate 2 is reduced in strength due to deterioration, the stress is dispersed and the roof base plate 2 is not damaged and the installation strength is stable. It is preferable in that it can be obtained. Moreover, the arrangement position of the rafters is confirmed as in the case where the fixing tool is driven and fixed to the rafters, and the workability is excellent because the rafter positions are not restricted.
図5は、他の実施形態を例示している。前記実施態様と異なる内容について説明し、それ以外は図中に表れた主要な構成に同じ符号を付すのみとする。本形態の取付具5は、前記と同様に縦長円筒形状の筒部7と、屋根下地板2に固着される固定部8と、支持体4を取付ける装着部9とからなる。本形態の固定部8は、屋根勾配と直角方向に並ぶ一対の固定片8B、8Bを有し、かつ装着部9も同方向に並ぶ一対の固定脚片9B、9Bを設け、筒部7、固定片8A及び固定脚片9Bを連続して貫通するビス37により筒部7と、固定部8と、装着部9とが一体化される。また本形態の装着部9は、上板9Aの両側縁が上に折れ曲がる一対の挟持片9C、9Cを設けることによりコ字状をなし、縦レール(図示せず)を、挟持片9C、9C内に嵌合することにより安定的に支持できる点で好ましい。   FIG. 5 illustrates another embodiment. The contents different from the above embodiment will be described, and other than that, only the same reference numerals are given to the main components appearing in the figure. The fixture 5 of this embodiment includes a vertically long cylindrical tube portion 7, a fixing portion 8 fixed to the roof base plate 2, and a mounting portion 9 to which the support body 4 is attached. The fixed portion 8 of this embodiment has a pair of fixed pieces 8B and 8B arranged in a direction perpendicular to the roof slope, and a pair of fixed leg pieces 9B and 9B arranged in the same direction. The cylindrical portion 7, the fixed portion 8, and the mounting portion 9 are integrated by a screw 37 that continuously passes through the fixed piece 8 </ b> A and the fixed leg piece 9 </ b> B. Further, the mounting portion 9 of this embodiment has a U-shape by providing a pair of sandwiching pieces 9C and 9C in which both side edges of the upper plate 9A are bent upward, and a vertical rail (not shown) is sandwiched between the sandwiching pieces 9C and 9C. It is preferable at the point which can support stably by fitting in.
図6、7は、更に他の実施形態を例示している。本形態の切欠部6は、屋根材3に矩形状に開口して形成される。そして切欠部6の周縁部は、シーリング材46を充填することにより水密封止される。   6 and 7 illustrate yet another embodiment. The notch 6 of this embodiment is formed by opening the roof material 3 in a rectangular shape. And the peripheral part of the notch part 6 is watertightly sealed by filling the sealing material 46.
また、前記切欠部6に向き合う屋根下地板2に穿設された4個の取付孔16に、拡開固着具15が挿入される。本形態の拡開固着具15は、図7に示すように、ネジ棒から成る挿通部17と、この挿通部17の下端に、略中央部を軸着されることにより揺動可能な棒状の抜け止め部18とからなる。そしてこの抜け止め部18が縦方向に向いて挿通部17に沿う状態で前記取付孔16に上から挿入され、抜け止め部18が取付孔16通過後、水平に回動して拡開することにより前記抜け止め部18は屋根下地板2に係合し、その結果挿通部17を上方に引き上げてもこれに抗して、屋根下地板2の上に抜け出すことができない。   Further, the expanding and fixing tool 15 is inserted into the four mounting holes 16 formed in the roof base plate 2 facing the notch 6. As shown in FIG. 7, the expanding and fixing tool 15 of this embodiment includes an insertion portion 17 made of a screw rod and a rod-like shape that can swing by being pivotally attached to the lower end of the insertion portion 17. And a retaining portion 18. The retaining portion 18 is inserted from above into the mounting hole 16 in a state along the insertion portion 17 in the longitudinal direction, and the retaining portion 18 rotates horizontally after passing through the mounting hole 16 to expand. Thus, the retaining portion 18 engages with the roof base plate 2, and as a result, even if the insertion portion 17 is pulled upward, it cannot be pulled out onto the roof base plate 2 against this.
また本形態の取付具5は、図8に示すように、下に向いて開口するコ字体11Aと、このコ字体11Aの向合う縦片11A1、11A1の下端から各々外側に折れ曲がって伸び、取付孔44が穿設された取付フランジ11B、11Bとを有してハット状をなし、かつ上に向く固定ボルト10を設けた固定金具11により構成されたものを例示している。そしてこの固定金具11は、前記拡開固着具15の挿通部17を取付孔44に挿入するとともにナット45を螺装してネジ止めすることにより、前記抜け止め部18の屋根下地板2に対する係合を利用して、屋根下地板2に固着される。このように、本形態の固定金具11は、両側に形成された平面状の取付フランジ11Bを用いて屋根下地板2に固定されるため、太陽電池モジュールMを安定して取付けしうる。   Further, as shown in FIG. 8, the fixture 5 of the present embodiment is bent outwardly from the lower end of the U-shaped body 11A opening downward and the vertical pieces 11A1 and 11A1 of the U-shaped body 11A facing each other. An example is shown in which the mounting flange 11B, 11B in which the hole 44 is drilled has a hat shape, and the fixing bracket 11 is provided with a fixing bolt 10 facing upward. The fixing bracket 11 is formed by inserting the insertion portion 17 of the expansion fixture 15 into the mounting hole 44 and screwing the nut 45 to the roof base plate 2 by screwing the nut 45 into the fixing hole 11. It is fixed to the roof base plate 2 using the joint. Thus, since the fixing bracket 11 of this embodiment is fixed to the roof base plate 2 using the planar mounting flanges 11B formed on both sides, the solar cell module M can be mounted stably.
本形態では、切欠部6及び前記固定金具11を覆う被覆カバー12が取付けられる。そしてこの被覆カバー12は、カバー本体13と、このカバー本体13の上に嵌合されるキャップ14との二重に構成され、前記切欠部6及び固定金具11を取付けた取付孔16の上を覆うことにより水密性を高めている。前記カバー本体13は、図8に示すように、固定金具11の上方を囲むホームベース状のシェル部13Aと、このシェル部13A周縁から、屋根勾配上方及び両側方に向けて屋根面に沿って伸びる鍔部13Bとからなり、シェル部13Aには前記固定ボルト10の挿入及びその位置調整を可能とするための切欠き48を設ける。そして鍔部13Bはその屋根勾配上端部が、切欠部6を設けた屋根材3と、その勾配上に配される屋根材3との間に挿入されるとともに固着具49により固定される。このようにカバー本体13は、屋根面に沿う鍔部13Bを有するため、屋根面上で安定した取付けられるとともに雨仕舞が良好となる。   In this embodiment, a cover 12 that covers the notch 6 and the fixing bracket 11 is attached. The covering cover 12 is composed of a cover main body 13 and a cap 14 fitted on the cover main body 13, and covers the mounting hole 16 to which the notch 6 and the fixing bracket 11 are attached. The water tightness is enhanced by covering. As shown in FIG. 8, the cover main body 13 includes a home base-like shell portion 13A surrounding the upper portion of the fixing bracket 11, and the periphery of the shell portion 13A from the periphery of the roof portion toward the roof slope and toward both sides. The shell portion 13A is provided with a notch 48 for enabling the insertion of the fixing bolt 10 and adjusting the position thereof. The upper end portion of the roof slope 13B is inserted between the roof material 3 provided with the notch 6 and the roof material 3 arranged on the slope and is fixed by the fixing tool 49. Thus, since the cover main body 13 has the collar part 13B along the roof surface, it can be stably mounted on the roof surface and the rain performance is good.
キャップ14は、シェル部13Aと同形かつシェル部13Aの上に嵌合できるように、シェル部13Aよりも少し大きく形成されている。このように、カバー本体13のシェル部13Aとキャップ14とで二重防水を構成するため、良好な雨仕舞効果が得られる。またキャップ14は、その上面に固定ボルト10を挿通するボルト孔47を有し、このボルト孔47から突出する固定ボルト10に、支持体取付金具50が螺着される。これにより、前記支持体取付金具50は前記被覆カバー12を介して固定金具11上に安定して固定される。   The cap 14 has the same shape as the shell portion 13A and is formed slightly larger than the shell portion 13A so as to be fitted on the shell portion 13A. Thus, since the double waterproofing is comprised by the shell part 13A and the cap 14 of the cover main body 13, a favorable rain effect is obtained. Further, the cap 14 has a bolt hole 47 through which the fixing bolt 10 is inserted on the upper surface thereof, and the support fitting 50 is screwed onto the fixing bolt 10 protruding from the bolt hole 47. Thereby, the support body mounting bracket 50 is stably fixed on the fixing bracket 11 via the covering cover 12.
太陽電池モジュールMを支持する支持体4を構成する縦レール51は、図7に示すように、コ字状のレール本体51Aの両側に、外方に伸びる水平な翼片51B、51Bを設ける。前記支持体取付金具50は、その一側部に内側に向いて開く取付溝52を有し、この取付溝52に前記縦レール51の一方の翼片51Bを嵌合するとともに、他方の翼片51Bを支持体取付金具50に螺着された押片53で挟着することにより、縦レール51が固定される。   As shown in FIG. 7, the vertical rail 51 which comprises the support body 4 which supports the solar cell module M equips the both sides of the U-shaped rail main body 51A with the horizontal blade piece 51B and 51B extended outward. The support mounting bracket 50 has a mounting groove 52 that opens inward on one side thereof, and fits one wing piece 51B of the vertical rail 51 into the mounting groove 52 and the other wing piece. The vertical rail 51 is fixed by clamping 51B with the pressing piece 53 screwed to the support body mounting bracket 50.
