【発明の属する技術分野】
本発明は、太陽光利用機器（太陽電池装置や集熱器）等の平板状の屋根設置体を、住宅の屋根に設置する際に用いる屋根用固定装置用いて固定する構造に関するものである。
【０００２】
【従来の技術】
近年、地球環境問題への関心の高まりとともに、自然エネルギーを利用した新エネルギー技術のひとつとして、太陽電池により太陽エネルギーを電力に変換して利用する太陽光発電システムが注目され、その実用化が加速されてきている。
【０００３】
家屋等の屋根と一体的に多数の太陽電池モジュールを取り付ける場合、係止用開口部を有した直線状のレール溝を設けた基台と、該基台上に配置された前記屋根設置体の周縁部を押圧固定するための押圧部材と、前記レール溝に沿って移動可能でかつ前記係止用開口部に係合させながら前記押圧部材を固定するための締結部材とを備えて成る屋根用固定装置が提案されている。
【０００４】
例えば図１０に示すように、屋根の流れ方向（雨の流れ方向）における最下段の太陽電池モジュール５０は、開口部５２ａが狭くなったレール溝５２を備えた基台５７上に配設され、この基台５７に設けられた押圧部材５３が太陽電池モジュール５０の周縁部に取り付けられた枠部材５１に係合した状態で、押圧部材５３と基台５７のレール溝５２との間で締結部材（ボルト５５，ナット５６）で固定され、さらに、枠部材５１が軒先カバー５４に係合されて固定されている。この場合、締結部材で固定する前に軒先カバー５４と枠部材５１とを図中Ｃ位置で係合させて、図中Ａ，Ｂの位置で締め付け固定されている（特許文献１等を参照）。

【０００６】
【発明が解決しようとする課題】
しかしながら、上述の技術では軒先カバー５０が締結部材を覆うような構造であり、軒先カバー５０だけを外すことが困難であるので、軒先カバー５０が覆われた状態で締結部材の締め込みや緩める作業を行なうことは困難である。
【０００７】
また、軒先カバー５０は断面積が比較的大きく、最下段の太陽電池モジュール５０の全幅に亘って取り付けるために、部材重量が増加する。
【０００８】
また、一旦太陽電池モジュール５０を設置した後に、例えば、軒先カバー５４を雪止め仕様への変更が必要になった際などに、軒先カバー５４のみを取り外したくとも、太陽電池モジュール５０をも取外して交換する必要があり作業性が著しく悪い。
【０００９】
そこで、本発明は上述の諸事情に鑑みてなされたものであり、軒先に取り付ける各部材の取り付け作業が容易で施工工数が低減でき、部材重量の軽減もでき、また、交換の際にも太陽電池モジュールを取り外すことなく容易に作業ができ、しかも設置外観も損なうことのない屋根設置体の固定構造を提案することを目的とする。
【００１０】
【課題を解決するための手段】
上記目的を達成するために、本発明の屋根設置体の固定構造は、係止用開口部を有したレール溝を設けた基台と、該基台上に配置される平板状をなす屋根設置体の周縁部を押圧固定するための押圧部材と、前記レール溝に沿って前記係止用開口部に係合させた状態で前記押圧部材を固定するための締結部材とを備えて成る屋根用固定装置を用いた前記屋根設置体の固定構造であって、前記基台上に、前記屋根設置体の軒先側辺と、前記締結部材の上方に開口部を位置させ前記押圧部材で固定したカバー固定部材とを配設するとともに、前記屋根設置体の軒先側辺に前記カバー固定部材を覆う軒先カバーを取付けたことを特徴とする。
【００１１】
また、係止用開口部を有したレール溝を設けた基台と、該基台上に配置される平板状をなす屋根設置体の周縁部を押圧固定するための押圧部材と、前記レール溝に沿って前記係止用開口部に係合させた状態で前記押圧部材を固定するための締結部材とを備えて成る屋根用固定装置を用いた前記屋根設置体の固定構造であって、前記基台上に、前記屋根設置体の軒先側辺と、前記締結部材の上方に開口部を備え前記押圧部材と一体に形成されたカバー固定部材とを配設するとともに、前記屋根設置体の軒先側辺に前記カバー固定部材を覆う軒先カバーを取付けたことを特徴とする。
【００１２】
このような固定構造により、締結部材を締め付ける際に、従来構造では軒先レールが邪魔になっていたが、本発明では軒先カバーとカバー固定部材に分割されているため、軒先カバー取り付け前に締結部材の締め付けが行え、円滑に作業が実施でき工数が低減できる。同時に、軒先カバーとカバー固定部材に分割されていることにより、カバー固定部材は太陽電池モジュールの軒先側の全幅に亘って存在する必要はなく、基台もしくは押圧部材の幅分有れば機能を満たすため部材重量が軽くて済む。
【００１３】
また、従来構造では最下段の太陽電池モジュールを取り外さないと軒先レールが取り外せなかったが、本発明の固定構造では太陽電池モジュールを取り外すことなく軒先カバーの脱着が可能であり、設置後に軒先カバーを交換する必要が生じた場合でも容易に交換できる。
【００１４】
【発明の実施の形態】
以下、平板状の屋根設置体である太陽電池モジュールを屋根上に配設する場合を例にとり、本発明に係る実施形態を模式的に図示した図面に基づいて詳細に説明する。
【００１５】
図１（ａ）〜（ｃ）、及び図２（ａ）〜（ｂ）に、本発明の屋根用固定装置Ｋの組立手順を説明するための斜視図を示す。本発明の屋根用固定装置Ｋは、係止用開口部２ａを有した直線状のレール溝２を１以上設けた板状の基台１と、この基台１上に配置されたレール固定部材を押圧固定するための板状の押圧部材４と、レール溝２に沿って移動可能でかつ係止用開口部２ａに係合させながら押圧部材４を固定するための締結部材であるボルト５，ナット６とを備えて成る。
【００１６】
ここで、基台１は例えばアルミニウム等の軽量で強度に優れた金属材料で構成される。また、この基台１の左右両端部１ａにはレール溝２が少なくとも１以上、直線状に設けられ、基台１の中央部１ｂは溝（または凹部）に形成されており、この溝（または凹部）には後記する屋根材に固定するための釘孔である貫通孔１ｃが複数設けられている。レール溝２は図示のように２本とするのが構造が簡単であり、しかも堅固に押圧部材４を取付けることができ望ましい。
【００１７】
また、レール溝２はその最上部に溝幅が急に狭くなった係止用開口部２ａが形成されているが、必ずしもレール溝２の最上部でなくともよい。すなわち、図１（ａ）の図示Ａ１方向に締結部材を取付けた押圧部材４を基台１上でスライドさせ、図１（ｂ）の図示Ａ２方向へ自在にスライドさせることが可能であり、溝幅が適度に狭く押圧部材４を固定するためのボルト５の頭部５ａを係合させることができればよく、その場所は特定されない。
【００１８】
また、押圧部材４はこれで押圧される部材より硬く、例えばステンレス等の導電性を有し強度的にも優れた金属材料から構成される。押圧部材４の横方向（レール溝２の長手方向に対し直交する方向）には、カバー固定部材７を押圧固定するための押圧部である押圧片４ｂが設けられ、さらに、この押圧片の角部４ｃは傾斜角が鋭角になるように傾斜面に形成され、この角部４ｃでカバー固定部材７を押圧するようにしている。また、この押圧部材４には後記する太陽電池モジュールのフレーム部材１６を押圧するための押圧片４ｂと同様な形状でこれとは押圧部が逆向きである押圧片４ｅ、及び係合片４ｆが設けられている。また、押圧部材４の中央部４ａにはボルト５を挿通させる貫通孔４ｄが形成されている。なお、ここで押圧部材４とカバー固定部材６は図８に示す通り一体であってもよい。また、図２ではカバー固定部材７は押圧部材４よりやや広い幅になっているが、後述する軒先カバー８と同様に太陽電池モジュールの幅にわたって一体的につながっていてもよい。
【００１９】
また、図１に示すように、ボルト５は押圧部材４の貫通孔４ｄに挿通されナット６で締めつけることにより、溝幅が急に狭くなった係止用開口部３によりボルト５の頭部５ａが係合され、押圧部材４は基台１に堅固に固定される。
【００２０】
また、図２（ａ），（ｂ）に示すように、カバー固定部材７は基台１のレール溝２に形成された凹部３（図１を参照）に下部を挿入させて固定される。また、カバー固定部材７はその上方に突出させた係合片７ａ、この係止片７ａから上部横方向（太陽電池モジュールの配置側）へ突出させ軒先カバー８を支持するための支持片７ｂ、押圧部材４の押圧片４ｃで押圧され基台１へ載置される断面Ｌ字状の支持片７ｃ、軒先側の横方向へ突出させ基台１へ載置される支持片７ｄ、この支持片７ｄから上方へ突出させ軒先カバーに係合される係合片７ｅ等を備えている。このカバー固定部材７に軒先カバー８を係合させて取り付ける。
【００２１】
軒先カバー８は表面側が湾曲しており、その軒先側端部はカバー固定部材７の係合片７ｅに係合される係合片８ａが形成されており、カバー本体の裏面には空洞部８ｂが形成されカバー固定部材７の係合片７ａと係合するとともに支持片７ｂ上で支持される。また、軒先カバー８の太陽電池モジュール設置側の端部には、下方に突設し太陽電池モジュールのフレーム部材と係合する係合片８ｃ、及び上方へ突設した突出片８ｄが形成されている。なお、軒先カバー８の寸法は太陽電池モジュール１枚から数枚の幅とほぼ同寸法で取り扱いに適した寸法とするとよい。
【００２２】
このように、本発明の固定構造は、図１，図２，図６に示すように、係止用開口部２ａを有したレール溝２を設けた基台１と、該基台１上に配置される平板状をなす太陽電池モジュールの周縁部を押圧固定するための押圧部材４と、レール溝２に沿って係止用開口部２ａに係合させた状態で押圧部材４を固定するための締結部材とを備えて成る屋根用固定装置Ｋを用いて、基台１上に、太陽電池モジュールの軒先側辺と、締結部材の上方に開口部を位置させ押圧部材４で固定したカバー固定部材７とを配設するとともに、太陽電池モジュールの軒先側辺にカバー固定部材７を覆う軒先カバー８を取付けた構成としている。
【００２３】
さらに、図３（ａ）〜（ｃ）に示すように、基台１にはその中央部１ｂにビス９や釘を挿入するための貫通孔１ｃが形成されており、基台１はスレートなどの屋根材１０、屋根下地材１１及び垂木１２にビス９や釘等を打ち込むことにより固定される。この際に、ビス９や釘を挿入する孔の防水を行うため、基台１と屋根材１０との間に例えばＥＰＤＭ（エチレン・プロピレン・ジエン・ラバー）等の弾性部材であるシール材１３を介在させるとよい。基台１の下面１ｄにこのシール材１３を貼着させるが、この基台１の下面１ｄにおけるシール材１３の接着面は中央部が窪んだ形状になっており、シール材１３をこの面に貼り付け、ビス９などを屋根材１０及び屋根下地材１１等に打ち込んだ際に、その圧力により基台１の貫通孔１ｃにシール材１３が入り込むことで防水性能をいっそう高まるようにしている。
【００２４】
図４（ａ）に屋根上に敷設された屋根材１０に、屋根用固定装置の多数を配設した様子を示す。また、多数の屋根用固定装置の中で本発明による屋根用固定装置は、図４（ｂ）に拡大図にて示すように軒先側の最下段に位置させる。
【００２５】
図５（ａ）に太陽電池モジュールＰの斜視図を、図５（ｂ）に太陽電池モジュールＰの多数を上記屋根用固定装置Ｋで固定する様子を示す。本発明による屋根用固定装置Ｋは図５（ｂ）に示すように、最下段の太陽電池モジュールＰの軒先側に位置する。ここで、図中１５は太陽電池本体を示し、１６は太陽電池本体１５の周縁部を固定するフレーム部材であり、アルミニウム等の軽量で強度的に優れた金属材料で構成される。
【００２６】
太陽電池モジュールＰは、少なくとも２辺が互いに平行の平面角形状をなし、例えば矩形状、台形状、平行四辺形状、その他４角形以外も含む角形状をなすものとし、この太陽電池モジュールＰを構成する太陽電池本体１５には、透光性の基板に配設された透光性の樹脂等の充填材中に太陽電池素子を多数接続したものが使用される。また、太陽電池素子には、例えばシリコン系半導体やガリウムヒ素から成る化合物半導体等を用い、単結晶、多結晶、もしくは非晶質等の材料からなる。
【００２７】
また、基台１は屋根の流れ方向に垂直な方向では、屋根材１０の働き寸法または垂木１２の敷設ピッチなどに依存して配置される。屋根の流れ方向に垂直な方向の屋根材１０の働き寸法または垂木１２の敷設ピッチなどは、それぞれの屋根材及び住宅により均一ではなく、例えば３００ｍｍ〜１０００ｍｍ程度と幅がある。本発明の設置方式の場合、図５から分かるように、太陽電池本体１５に設けられた軒先側のフレーム部材１６に対して押圧部材４がどの位置にあっても、太陽電池モジュールを紙面に垂直な方向で移動させることができる構造なので、自由に位置調整が可能となる。
【００２８】
また、屋根用固定装置Ｋは、屋根の流れ方向に垂直な方向で、屋根材または垂木等の働き寸法に依存した位置に設置される。しかし、上述のように太陽電池モジュールＰのフレーム１６には屋根の流れ方向に垂直な方向に対して、自由に位置を調整できる機構を有しているので、屋根の流れ方向に垂直な方向の太陽電池モジュールの働き寸法と、屋根材または垂木等の働き寸法はそれぞれ相違する寸法であってもよい。
【００２９】
また、太陽電池モジュールＰを電気的に導通させ接地させる際には、太陽電池モジュールＰを固定する押圧部材４を利用して、太陽電池モジュールＰを固定する際に太陽電池モジュールＰのフレーム部材１６に施されているアルマイト皮膜やクリア塗装等を破ることにより、屋根の流れ方向の太陽電池モジュールＰどうしを電気的に導通させることができ、太陽電池モジュールが漏電した際にも安全性を確保できる。
【００３０】
次に、本発明の他の実施形態について図７を用いて説明する。屋根用固定装置Ｋの軒先カバー８の下方先端部には、図に示すような解放爪８ｅを設けている。設置後軒先カバー８を取り外す場合、カバー固定部材７と軒先カバー８の係合を解放する必要があるが、図示した構造にすることにより、マイナスドライバーＤなどの工具を用いて、てこの原理により容易に係合部を解放することができる。
【００３１】
次に、さらに他の実施形態について図８を用いて説明する。屋根用固定装置Ｋの軒先カバー８の上部には図に示すような突出片８ｆを設けている。この突出片８ｆは、積雪の際に落雪を防止するための雪止めの機能を有するものである。太陽電池は、積雪すると日射を受けても発電しないためできるだけ積雪しない方がよいが、降雪の多い地方ではむやみに落雪すると周辺に被害を与える場合があるので、雪止め機構が求められる。できるだけ発電が可能なように突出片８ｆを設けない軒先カバー８を一旦取り付けた場合にも、このような突出片８ｆを設けた軒先カバー８に容易に交換が可能である。すなわち、カバー固定部材７までが共通の構造であるため軒先カバー８のみの交換で済む。また、前述のように本発明の構造にすることにより、太陽電池モジュール１５を外すことなく、軒先カバー８の交換が可能である。
【００３２】
さらに、図９に示すように、上述したカバー固定部材７と押圧部材４と一体に形成したカバー固定部材７４を設けてもよい。すなわち、基台上に、屋根設置体である太陽電池モジュールの軒先側辺と、前記した締結部材の上方に開口部を備え押圧部材４と一体に形成されたカバー固定部材７４とを配設するとともに、太陽電池モジュールの軒先側辺にカバー固定部材７４を覆う軒先カバー８を取付けた構成としてもよい。これにより、構成が簡便となり、構成部材が少なくて済み全体の軽量化や取付け・取り外し等の作業の簡便化を図ることができる。
【００３３】
なお、本実施形態では屋根設置体として太陽電池モジュールを例にとり説明したが、これに限定されるものではなく、太陽熱集熱器等の平板状の太陽エネルギー利用機器等に好適に適用可能であることは容易に理解される。
【００３４】
【発明の効果】
以上説明したように、本発明の屋根設置体の固定構造によれば、屋根設置体が屋根材の上に設置される場合において、最下段の軒先部の取付において、締結部材の締め込みが容易で作業工数の低減が図れる。
【００３５】
また、軒先カバーのみを全幅に亘って施工するようにできるため部材重量の軽減ができる。
【００３６】
また、軒先カバーのみを取り外し可能であるため、軒先カバーの交換が容易に行え、その上、その取り外し作業を簡便に行える。
【００３７】
以上により、屋根設置体の特性や外観を損なうことのない優れた固定構造を提供できる。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for fixing a flat roof installation body such as a solar-powered device (a solar cell device or a heat collector) using a roof fixing device used for installation on a roof of a house.
[0002]
[Prior art]
In recent years, with the growing interest in global environmental issues, solar power generation systems that convert solar energy into electric power using solar cells have attracted attention as one of the new energy technologies that use natural energy, and their practical use has accelerated. Have been.
[0003]
When mounting a large number of solar cell modules integrally with a roof of a house or the like, a base provided with a linear rail groove having an opening for locking, and a roof installation body disposed on the base are provided. For a roof comprising: a pressing member for pressing and fixing a peripheral portion; and a fastening member that is movable along the rail groove and fixes the pressing member while engaging with the opening for locking. Fixing devices have been proposed.
[0004]
For example, as shown in FIG. 10, the lowermost solar cell module 50 in the roof flow direction (rain flow direction) is disposed on a base 57 provided with a rail groove 52 having a narrow opening 52a. When the pressing member 53 provided on the base 57 is engaged with the frame member 51 attached to the peripheral portion of the solar cell module 50, a fastening member is formed between the pressing member 53 and the rail groove 52 of the base 57. (Bolts 55, nuts 56), and the frame member 51 is engaged with and fixed to the eaves cover 54.

[0005]
[Patent Document 1]
Japanese Patent Application No. 2001-294051 [0006]
[Problems to be solved by the invention]
However, according to the above-described technology, the eaves cover 50 covers the fastening member, and it is difficult to remove only the eaves cover 50. Therefore, the work of tightening and loosening the fastening member with the eaves cover 50 covered is performed. Is difficult to do.
[0007]
Further, the eaves cover 50 has a relatively large cross-sectional area and is attached over the entire width of the lowermost solar cell module 50, so that the weight of the member increases.
[0008]
Further, once the solar cell module 50 is installed, for example, when it is necessary to change the eaves cover 54 to the snow stopper specification, even if the eaves cover 54 only needs to be removed, the solar cell module 50 is also removed. It is necessary to replace, and workability is remarkably bad.

Therefore, the present invention has been made in view of the above-mentioned circumstances, and the work of mounting each member to be mounted on the eaves is easy, the number of construction steps can be reduced, the weight of the member can be reduced, and the solar cell can be easily replaced. An object of the present invention is to propose a fixing structure of a roof installation body which can be easily operated without removing a battery module and does not impair the installation appearance.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, a fixing structure of a roof installation body of the present invention includes a base provided with a rail groove having an opening for locking, and a roof installation having a flat plate shape disposed on the base.

An eaves cover that covers the cover fixing member is attached to a side.
[0012]
With such a fixing structure, when the fastening member is tightened, the eaves rail is obstructed in the conventional structure, but in the present invention, since the eaves rail is divided into the eaves cover and the cover fixing member, before the eaves cover is attached, Can be tightened, work can be performed smoothly, and man-hours can be reduced. At the same time, by being divided into the eaves cover and the cover fixing member, the cover fixing member does not need to exist over the entire width of the eaves side of the solar cell module, and functions as long as it has the width of the base or the pressing member. The weight of the member is light to satisfy.
[0013]
Also, in the conventional structure, the eaves rail could not be removed without removing the bottom solar cell module, but with the fixed structure of the present invention, the eaves cover can be attached and detached without removing the solar cell module, and the eaves cover is installed after installation. Even if it becomes necessary to replace it, it can be easily replaced.

[0024]
FIG. 4A shows a state in which many roof fixing devices are arranged on a roofing material 10 laid on the roof. Further, among the many roof fixing devices, the roof fixing device according to the present invention is located at the lowermost stage on the eaves side as shown in an enlarged view in FIG.
[0025]
FIG. 5A shows a perspective view of the solar cell module P, and FIG. 5B shows how a large number of the solar cell modules P are fixed by the roof fixing device K. The roof fixing device K according to the present invention is located on the eaves side of the lowermost solar cell module P as shown in FIG. Here, in the figure, reference numeral 15 denotes a solar cell main body, and reference numeral 16 denotes a frame member for fixing a peripheral portion of the solar cell main body 15, which is made of a lightweight and strong metal material such as aluminum.
[0026]
The solar cell module P has a planar angular shape with at least two sides parallel to each other, for example, a rectangular shape, a trapezoidal shape, a parallelogram shape, and an angular shape including other than a quadrangular shape. The solar cell main body 15 is formed by connecting a large number of solar cell elements in a filler such as a light-transmitting resin provided on a light-transmitting substrate. The solar cell element is made of, for example, a single-crystal, polycrystalline, or amorphous material using a silicon-based semiconductor or a compound semiconductor made of gallium arsenide.
[0027]
The base 1 is arranged in a direction perpendicular to the flow direction of the roof depending on the working dimensions of the roofing material 10 or the laying pitch of the rafters 12. The working dimensions of the roofing material 10 or the laying pitch of the rafters 12 in the direction perpendicular to the flow direction of the roof are not uniform among the respective roofing materials and houses, and have a width of, for example, about 300 mm to 1000 mm. In the case of the installation method of the present invention, as can be seen from FIG. 5, the solar cell module is perpendicular to the paper surface regardless of the position of the pressing member 4 with respect to the eaves side frame member 16 provided in the solar cell main body 15. Since the structure can be moved in various directions, the position can be freely adjusted.
[0028]
The roof fixing device K is installed in a direction perpendicular to the flow direction of the roof at a position depending on the working dimensions of the roof material, rafters, or the like. However, as described above, since the frame 16 of the solar cell module P has a mechanism capable of freely adjusting the position in the direction perpendicular to the flow direction of the roof, the frame 16 in the direction perpendicular to the flow direction of the roof is provided. The working dimensions of the solar cell module and the working dimensions of the roof material or rafters may be different dimensions.
[0029]
Further, when the solar cell module P is electrically connected and grounded, the pressing member 4 for fixing the solar cell module P is used to fix the frame member 16 of the solar cell module P when fixing the solar cell module P. By breaking the alumite film or clear coating applied to the roof, the solar cell modules P in the flow direction of the roof can be electrically connected to each other, and safety can be ensured even when the solar cell module leaks electricity. .
[0030]
Next, another embodiment of the present invention will be described with reference to FIG. At the lower end of the eaves cover 8 of the roof fixing device K, a release claw 8e as shown in the figure is provided. When removing the eaves front cover 8 after installation, it is necessary to release the engagement between the cover fixing member 7 and the eaves front cover 8. However, by using the illustrated structure, the principle of leverage can be achieved by using a tool such as a flathead screwdriver D. The engaging portion can be easily released.
[0031]
Next, still another embodiment will be described with reference to FIG. A protruding piece 8f as shown in the figure is provided on the upper part of the eaves cover 8 of the roof fixing device K. The protruding piece 8f has a snow stopper function for preventing falling snow when snow is accumulated. It is better not to snow the solar cell as much as possible because it does not generate electricity even if it receives solar radiation when it is snowed. However, in regions where there is a lot of snow, if snow falls unnecessarily, it may damage the surrounding area. Even when the eaves cover 8 without the protruding piece 8f is once attached so that power can be generated as much as possible, the eaves cover 8 provided with such a protruding piece 8f can be easily replaced. That is, since the structure up to the cover fixing member 7 is common, only the eaves cover 8 needs to be replaced. Further, by adopting the structure of the present invention as described above, the eaves cover 8 can be replaced without removing the solar cell module 15.
[0032]
Further, as shown in FIG. 9, a cover fixing member 74 integrally formed with the cover fixing member 7 and the pressing member 4 described above may be provided. That is, on the base, the eaves side of the solar cell module as the roof installation body and the cover fixing member 74 having an opening above the fastening member and integrally formed with the pressing member 4 are arranged. In addition, an eaves cover 8 that covers the cover fixing member 74 may be attached to the eaves side of the solar cell module. Accordingly, the configuration is simplified, the number of components is reduced, and the weight of the whole is reduced, and operations such as attachment and detachment can be simplified.
[0033]
In the present embodiment, the solar cell module has been described as an example of the roof installation body. However, the present invention is not limited to this, and can be suitably applied to a flat solar energy utilizing device such as a solar heat collector. That is easily understood.
[0034]
【The invention's effect】
As described above, according to the fixing structure of the roof installation body of the present invention, when the roof installation body is installed on the roof material, the fastening member can be easily tightened when the lowermost eaves are mounted. Thus, the number of man-hours can be reduced.
[0035]
Also, since only the eaves cover can be constructed over the entire width, the weight of members can be reduced.
[0036]
Moreover, since only the eaves cover can be removed, the eaves cover can be easily replaced, and furthermore, the removal work can be performed easily.
[0037]
As described above, it is possible to provide an excellent fixing structure without impairing the characteristics and appearance of the roof installation body.
