Description

【0001】
【発明の属する技術分野】
この出願の発明は、機能部材取付装置およびそれを用いた機能部材取付構造に関するものである。さらに詳しくは、この出願の発明は、既存瓦に対して太陽電池瓦やアンテナなどの機能部材を、固定力が強く高度な防水機能を有しかつ意匠性高く取り付けることのできる機能部材取付装置およびそれを用いた機能部材取付構造に関するものである。
【0002】
【従来の技術】
近年、太陽エネルギーの利用策として屋根面への太陽電池瓦(モジュール)の配設が実用的に具体化され始めており、住宅等の建物の既存の屋根に対しても太陽電池瓦を施工することが行われている。しかしながら、既存の屋根面への太陽電池瓦の施工については既存の瓦を取り外した後に施工すると非常に手間がかかり、しかも廃材が大量に発生することから、既存の瓦をそのままにして、その上に太陽電池瓦を葺くことが検討され、かつ、実施され始めている。
【0003】
従来の既存瓦の上に太陽電池瓦を設置させる方法では、たとえば図10に示したように、既存瓦(81)(図10ではストレート瓦)に固定金具(82)を用いて取付レール(83)を固定し、この取付レール(83)に太陽電池瓦(モジュール)(84)を固定している。このとき固定金具(82)を既存瓦(81)に固定するためにボルトや釘、木ネジなどを既存瓦(81)に貫通させるため、その部分から雨漏りなどが生じるのを防止する必要があり、防水シート・コーキングを固定金具(82)と既存瓦(81)の間に施すことによって防水処理を行っている。なお、図10においては図10(b)に示しているように、固定金具(82)を既存瓦(81)に固定するために木ネジ(85)を用い、また防水シート(86)を既存瓦(81)と固定金具(82)の間に配置させている。
【0004】
また一方で、従来より、地上波や衛星波を受信するためのアンテナを屋根面に設置しているが、アンテナを屋根面に設置する場合には、図11に示しているように、アンテナ(87)を屋根面の既存瓦(88)に固定するため、屋根の棟部(89)を跨ぐようにアンテナ固定用の支柱(90)を設置し、軒先(91)からアンテナ(87)までに複数のワイヤー(92)を張ることによって支柱(90)を屋根面に固定するといった方法が用いられている。
【0005】
【発明が解決しようとする課題】
しかしながら、従来の太陽電池瓦(84)の既存瓦(81)への取付構造の場合、既存瓦(81)と太陽電池瓦(84)の間に防水シート(86)、固定金具(82)および取付レール(83)が配置されているため、その分だけ太陽電池瓦(84)が既存瓦(81)の面よりも高くなることから、太陽電池瓦(84)の重心位置が既存瓦(81)上面と離れてしまい、地震や振動、強風等によって固定金具(82)と既存瓦(81)のビスによる固定力が低下する恐れがあり、長期の耐久性能には問題があった。
【0006】
また太陽電池瓦(84)が既存瓦(81)の面よりも相当高くなることから、太陽電池瓦(84)と既存瓦(81)の面の一体感が無くなり、外観上の違和感を与えてしまうことになる。
【0007】
さらに防水上の面においても、防水を固定金具(82)付近に配置させた防水シートやコーキングに頼っているため長期的な防水性に不安が残る。とくにコーキングの経年劣化によって雨漏りが生じる恐れは年月が経つほど増してしまうのである。
【0008】
また、一方、従来のアンテナ(87)の既存瓦(88)への取付構造の場合には、支柱(90)を複数のワイヤー(92)によって既存瓦(88)に固定しているためしっかりと固定できず、とくに衛星波の場合、画像が風によって乱れてしまうといったことがしばしば起こっていた。
【0009】
また、必ずアンテナ(87)の支持脚(93)が屋根の棟部を跨ぐように施工しなくてはならないため、施工性も悪く、またアンテナ(87)の既存瓦(88)への設置のために軒先(91)から屋根の棟部(89)まで複数のワイヤー(92)を張り巡らさなくてはならず、外観が非常に悪くなり意匠性の低いものとなってしまっていた。さらに、アンテナ(87)がワイヤー(92)で固定されているのみであることから、長期の耐候性・耐風性能が悪いといった欠点も有していた。
【0010】
そこで、この出願の発明は、以上のとおりの事情に鑑みてなされたものであり、従来技術の問題点を解消し、既存瓦に対して太陽電池瓦やアンテナなどの機能部材を、固定力が強く高度な防水機能を有しかつ意匠性高く取り付けることが可能な、機能部材取付装置およびそれを用いた機能部材取付構造を提供することを課題としている。
【0011】
【課題を解決するための手段】
この出願の発明は、上記の課題を解決するものとして、まず第1には、機能部材を既存瓦に施工するための機能部材取付装置であって、水平方向にスリット状の固定孔が形成されかつ裏面側周縁部に防水部が配設された固定板と、前記スリット状の固定孔を覆うように配置されるカバー材とを備え、前記固定板が、一枚もしくは複数枚配置された状態あるいは上端が重なるようにして段葺き状に複数枚配置された状態で既存瓦に前記スリット状の固定孔を通じてビスで固定可能とされ、かつ固定板もしくはカバー材に機能部材が取付可能とされていることを特徴とする機能部材取付装置を提供する。

【0020】
【発明の実施の形態】
この出願の発明の機能部材取付装置およびそれを用いた機能部材取付構造は、上記のとおりの特徴を持つものであるが、以下にその実施の形態について説明する。
【0021】
まず、太陽瓦電池瓦の既存瓦への取付構造について説明する。
【0022】
添付した図1は太陽電池瓦の既存瓦への取付構造について、その実施の形態を例示した斜視図である。この図1(a)および(b)に示しているように、たとえば太陽電池瓦と略同サイズであり、水平方向にスリット状の固定孔(1)が形成され、表面側に太陽電池瓦固定金具(2)が配設され、かつ、裏面側周縁部にEPDM(Ethylene Propylene Diene Monomer)樹脂、シリコンゴム等の防水材による防水部(3)が配設された固定板(4)が、棟側の上端が重なるようにして段葺き状に複数枚配置された状態で既存瓦にビス固定される。図1(c)は、固定板(4)が、スリット状の固定孔(1)に挿入されたビス(9)によって既存瓦(5)に固定された状態を示している。なおこのビス(9)にはシール材が設けられており、そのシール材が既存瓦(5)に密着するようにビス(9)を既存瓦(5)のビス孔に挿入し固定板(4)を既存瓦(5)に固定する。
【0023】
そして、図1(d)に示しているように、カバー材(7)によって固定板(4)の固定孔(1)が覆われ、図1(e)に示しているように太陽電池瓦固定金具(2)によって固定板(4)に太陽電池瓦(8)が固定される。
【0024】
この例示した構造において、固定板(4)が太陽電池瓦(8)と略同サイズであるというのは、固定金具(2)による太陽電池瓦(8)の固定構造や前記の段葺きのための重ね代による差異があるとして、固定板(4)は、太陽電池瓦(8)のサイズに近似するか、もしくはほぼ同サイズという意味である。もちろん、固定板(4)は必ずしも太陽電池瓦(8)と略同サイズである必要はない。ただ、太陽電池瓦(8)の既存の屋根面の配置において、略同サイズとすることが施工上は容易である。また、スリット状の固定孔(1)は、固定板(4)の強度を保った範囲で、すなわち固定孔(1)の存在によって固定板(4)が簡単に破損してしまわない程度に固定板(4)の水平方向、つまり横方向に設けられているものとする。このように固定孔(1)をスリット状に形成することによって、固定孔(1)の長さ分だけビス(9)による固定位置の選択自由度を有するため、現場施工において容易に固定板(4)を既存瓦(5)にビス固定することが可能となる。スリット状の固定孔(1)の水平方向の長さについては、固定板の水平方向のほぼ全長にわたるものとしてもよいし、それよりも短くてもよい。いずれの場合でも現場施工でのビス(9)による固定位置の選択自由度が大きなものとするのが望ましい。また、固定孔(1)は固定板(4)に複数設けることができ、通常2つ程度設けることによって着実に固定板(4)を既存瓦(5)に固定することができる。
【0025】
さらに、前記のカバー材(7)については、その機能は、スリット状固定孔(1)からの雨水等の侵入を防止することにあることから、このカバー材(7)は、固定板(4)のスリット状の固定孔(1)部、そしてビス(9)の頭部を密着して覆い防水性能が確保できるものとする。このため、カバー材(7)は、図2(b)に示したように、防水材、たとえば前記のEPDM樹脂やシリコンゴム等の防水部(6)をスリット状固定孔(1)やビス(9)頭部との当接部、さらにはその上面部に有しているものが望ましい。また、雨水等の水の流れを誘導するように、図1(d)並びに図2(a)(b)に示したように、その断面が、棟側に頂部があるクサビ形状とすることも望ましい。
【0026】
このようなカバー材(7)は、たとえば接着剤等を介して固定板(4)やビス(9)頭部に密着させることができる。
【0027】
この出願の発明の太陽電池瓦の既存瓦への取付構造は上記のような構造であることから、太陽電池瓦(8)と既存瓦(5)の間には、裏面側に防水部(3)が配設され表面側にカバー材(7)が装着された固定板(4)が配置されているのみであり、従来の太陽電池瓦の既存瓦への取付構造と比べて太陽電池瓦(8)の重心が既存瓦(5)の面に近いため、従来の太陽電池瓦の既存瓦への取付構造のように地震・振動、強風などによって固定金具と既存瓦面との固定力が低下するといった恐れが無い。
【0028】
また、この出願の発明の太陽電池瓦の既存瓦への取付構造は、太陽電池瓦(8)の面の高さを低く抑えることができるため、既存瓦(5)と太陽電池瓦(8)の段差が小さくなり外観も屋根全体としての一体感を得ることができる。さらにこの出願の発明の太陽電池瓦の既存瓦への取付構造は、従来の太陽電池瓦の既存瓦への取付構造には無かった段葺き構造となっているため、既存瓦(5)の段葺きと調和し、より自然な外観を得ることができる。
【0029】
さらに、この出願の発明の太陽電池瓦の既存瓦への取付構造では、たとえば図1(b)に示しているように固定板(4)の裏面側にEPDM(Ethylene Propylene Diene Monomer)樹脂等からなる防水部(3)が配設されており、かつ、たとえば図2(b)に示しているようにEPDM樹脂等からなる防水部(6)が上下面に取り付けられた断面クサビ形状のカバー材(7)が固定孔(1)全体を覆うように固定板(4)に装着されているため、従来の太陽電池瓦の既存瓦への取付構造のように既存瓦にボルトを貫通させて固定金具を固定した箇所から雨水が漏れてしまうといった恐れもなく、またコーキングの経年劣化による雨漏りの心配もない。
【0030】
また、従来の太陽電池瓦の既存瓦への取付構造で固定金具や取付レールなどを用いていたのに比べて、この出願の発明の機能部材取付装置および取付構造においては部材点数を少なくすることができ、またアルミフレームレスの機能部材を使用することでコスト削減を図ることが可能となる。
【0031】
次に、上記の構造の施工手順を以下に詳しく説明する。
【0032】
まず、たとえば図1(a)に示しているようなスリット状の貫通孔である固定孔(1)が水平方向に形成され、表面側に太陽電池瓦固定金具(2)が配設され、裏面側周縁部に図1(b)に示しているようなEPDM樹脂等からなる防水部(3)が配設された固定板(4)の固定孔(1)にビス(9)を通し、図1(c)に示しているように垂木を狙って既存瓦(5)にビス固定を行う。
【0033】
そして図3に示したように、先に固定した固定板(4)の横に設置列分の同様の固定板(4)を順に固定し、さらに図4に示しているようにそれら固定板(4)の棟側縁部(10)に新たに設置する固定板(4)の軒側縁部(11)が重なるように固定してゆく。
【0034】
その後、図1(d)および図2に示したように、固定板(4)に、断面形状がクサビ形状であり上面と下面にEPDM樹脂等からなる防水部(6)が取り付けられたアルミ押出し部材等からなるカバー材(7)を、固定孔(1)全体を覆うように装着する。
【0035】
次に、図1(e)および図5に示したように、固定板(4)の表面側に配設された太陽電池瓦固定金具(2)によって、太陽電池瓦(8)を挟むように固定する。このようにすることで太陽電池瓦(8)を既存瓦(5)に取り付けることが可能となり、最終的に図6のような完成状態となる。
【0036】
太陽電池瓦(8)と既存瓦(5)の間には防水材(3)およびカバー材(7)が取り付けられた固定板(4)のみが配置されているのみであるため、太陽電池瓦(8)と既存瓦(5)の距離が近くなり、従来の構造における太陽電池瓦(8)の既存瓦(5)への固定力の問題および意匠性の問題を解消することができる。 さらに、上記のようなカバー材(7)を固定孔(1)を覆うように固定板(4)に装着することから、雨漏りの恐れを回避することができる。
【0037】
また、他の実施形態として図7に示しているように既存瓦がスリット(12)を有しているスリット瓦(13)である場合、上記と同様に、固定板(4)をスリット瓦(13)にビス固定し、カバー材(7)で固定孔(1)を覆い、同様の固定板(4)を縦横に段葺き状に配置するのであるが、複数枚固定した固定板(4)の棟側最上端縁を覆うように板金(14)などの防水板をスリット瓦(13)に差し込みながら取り付けるようにすることも可能である。
【0038】
このようにすることによって、スリット瓦(13)に対しても、雨漏りの心配をすること無く太陽電池瓦(8)を施工することが可能となる。
【0039】
次に、アンテナの既存瓦への取付構造について説明する。
【0040】
アンテナの場合も、固定板が既存瓦に取り付けられる構造は太陽電池瓦の場合と同様であって、図1(a)および(b)に示しているように、水平方向にスリット状の固定孔(1)が形成され、かつ、裏面側周縁部にEPDM(Ethylene Propylene Diene Monomer)樹脂、シリコンゴム等の防水材による防水部(3)が配設された固定板(4)が、図1(c)に示しているように、スリット状の固定孔(1)に挿入されたビス(9)によって既存瓦(5)に固定される。そして、図1(d)に示しているように、カバー材(7)によって固定板(4)の固定孔(1)が覆われるのであるが、アンテナの場合、図8(a)および(b)に示しているように、そのカバー材(7)上に平板(15)とアンテナの支柱(16)が一体となったアンテナユニット(17)が固定される。
【0041】
アンテナユニット(17)のカバー材(7)への具体的な取付構造としては、図9に示しているように、カバー材(7)の上面の長手方向全長に亘って蟻溝(18)が形成されており、その蟻溝(18)にTボルト(19)が挿入されてTボルト(19)が蟻溝(18)内でスライド自在とされ、図8(a)に示しているように、そのTボルト(19)とナット(20)によりアンテナユニット(17)の平板(15)がカバー材(7)に固定される。
【0042】
なお、アンテナユニット(17)をカバー材(7)に取り付ける際には、カバー材(7)が固定板(4)に確実に固定されている必要があることから、太陽電池瓦の場合のようにカバー材(7)を接着剤で固定板(4)に取り付けるのではなく、図8に示しているようにカバー材(7)に形成された固定具(21)などにより、カバー材(7)が固定板(4)に強固かつ確実に固定されるように取り付けられる。
【0043】
上記のようにアンテナを屋根面の既存瓦に設置することによって、アンテナが屋根面へ確実に固定がされることから、従来のワイヤーを用いたアンテナの屋根面への固定の場合に発生していた、衛星波を受信した際に画像が風によって乱れるといった問題が回避され、アンテナの長期耐候性・耐風性を得ることができる。
【0044】
また、固定板およびカバー材に防水部が設けられているため、既存瓦の裏面に水が侵入するのを遮断することができる。
【0045】
また、ワイヤーでの固定とは違い、アンテナを屋根面に設置する際に支持脚を屋根の棟部を跨ぐように固定する必要もなく、アンテナを既存屋根面の任意個所に固定することが可能となり、さらにまた、アンテナを屋根面にワイヤーで固定しないため、ワイヤーのないすっきりした外観が得られ意匠性も高くなる。
【0046】
【発明の効果】
以上詳しく説明したとおり、この出願の発明によって、既存瓦に対して太陽電池瓦やアンテナなどの機能部材を、固定力が強く、高度な防水機能を有しかつ意匠性高く取り付けることが可能な、機能部材取付装置およびそれを用いた機能部材取付構造が提供される。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a functional member mounting device and a functional member mounting structure using the same. More specifically, the invention of this application is a functional member mounting device capable of mounting a functional member such as a solar cell tile or an antenna to an existing tile having a strong fixing function, a high waterproof function, and a high designability. The present invention relates to a functional member mounting structure using the same.
[0002]
[Prior art]
In recent years, the installation of photovoltaic tiles (modules) on the roof surface has started to be embodied practically as a means of using solar energy, and the installation of photovoltaic tiles on existing roofs of houses and other buildings has been started. Has been done. However, when installing solar cell tiles on the existing roof surface, removing the existing tiles would be very time-consuming and would result in a large amount of waste material. It has been studied and started to be practiced that solar cell tiles are to be roofed.
[0003]
In the conventional method of installing a solar cell roof tile on an existing roof tile, as shown in FIG. 10, for example, a mounting rail (83) is attached to an existing roof tile (81) (a straight roof tile in FIG. 10) by using a fixture (82). ) Is fixed, and a solar cell roof (module) (84) is fixed to the mounting rail (83). At this time, bolts, nails, wood screws, and the like are passed through the existing tile (81) in order to fix the fixing bracket (82) to the existing tile (81), so that it is necessary to prevent the occurrence of rain leakage or the like from that part. The waterproofing treatment is performed by applying a waterproof sheet caulking between the fixing bracket (82) and the existing roof tile (81). In FIG. 10, as shown in FIG. 10B, a wood screw (85) is used to fix the fixing bracket (82) to the existing tile (81), and a waterproof sheet (86) is used. It is arranged between the roof tile (81) and the fixture (82).
[0004]
On the other hand, conventionally, an antenna for receiving terrestrial waves and satellite waves is installed on the roof surface. However, when the antenna is installed on the roof surface, as shown in FIG. In order to fix 87) to the existing tile (88) on the roof surface, a pole (90) for fixing the antenna is installed so as to straddle the ridge (89) of the roof, and from the eaves (91) to the antenna (87). A method has been used in which the column (90) is fixed to the roof surface by stretching a plurality of wires (92).
[0005]
[Problems to be solved by the invention]
However, in the case of the conventional structure for mounting the solar cell tile (84) to the existing tile (81), the waterproof sheet (86), the fixing bracket (82) and Since the mounting rail (83) is arranged, the solar cell tile (84) is higher than the surface of the existing tile (81) by that amount, so that the center of gravity of the solar cell tile (84) is located at the same position as the existing tile (81). ) It may be separated from the upper surface, and the fixing force of the fixing metal (82) and the screw of the existing roof tile (81) may be reduced by an earthquake, vibration, strong wind, or the like, and there is a problem in long-term durability.
[0006]
Further, since the solar cell tile (84) is considerably higher than the surface of the existing tile (81), the sense of unity between the surface of the solar cell tile (84) and the existing tile (81) is lost, giving a sense of strangeness in appearance. Will be lost.
[0007]
Further, in terms of waterproofing, long-term waterproofing remains uneasy because the waterproofing depends on a waterproofing sheet or caulking disposed near the fixing bracket (82). In particular, the risk of rain leaks due to aging of the caulking increases with the passage of time.
[0008]
On the other hand, in the case of the mounting structure of the conventional antenna (87) to the existing tile (88), since the support (90) is fixed to the existing tile (88) by a plurality of wires (92), it is firmly fixed. Unable to fix, especially in the case of satellite waves, the image often became disturbed by the wind.
[0009]
Also, since the support leg (93) of the antenna (87) must be constructed so as to straddle the ridge of the roof, the workability is poor, and the antenna (87) can be installed on the existing tile (88). Therefore, a plurality of wires (92) had to be stretched from the eaves (91) to the roof ridge (89), and the appearance was very poor and the design was poor. Furthermore, since the antenna (87) is only fixed by the wire (92), there is a disadvantage that long-term weather resistance and wind resistance are poor.
