Description

【０００１】
【発明の属する技術分野】
本発明は、外装面を構築するための外装材又は上部外装構造を支持する支持材を保持する保持部材の取付構造及び外装構造に関する。
【０００２】
【従来の技術】
従来より、外装面（屋根面）を施工するには、外装材（屋根材）を固定又は保持するための保持部材を、下地である構造材に、ボルト等による締着や溶接等の接着によって固定し、その後、必要に応じて断熱材などを敷設して外装材（屋根材）を敷設していた。即ち外装面（屋根面）の取付強度及び安定性は、保持部材と構造材の取付安定性に大きく影響されるものであった。
【０００３】
【発明が解決しようとする課題】
しかしながら、保持部材を構造材にボルト等による締着によって固定する場合には、構造材にボルト等の締着具を貫通させるための孔を予め設ける必要がある上、締着具が構造材の裏面（フランジの下面側）に位置するため極めて作業性が悪いものであった。
また、保持部材を構造材に溶接によって固定する場合には、より具体的には構造材の固定箇所に墨出しを行い、その墨出し線に対して保持部材を溶接して固定するので、溶接時の墨出し線に対してずれが生じると位置がずれて働き幅が変わり、その結果、外装材の組み付け不良を起こすという問題があった。
【０００４】
【課題を解決するための手段】
本発明は、上記に鑑み提案されたもので、上フランジ部を有する構造材と上フランジ部に立設する保持部材の取付構造であって、前記構造材は、上フランジ部と、該上フランジ部から垂下する縦片部を有し、前記保持部材は、少なくとも１つ以上の係止部を備える取付部と、該取付部から上方へ延在する起立部と、外装材又は（上部外装構造を支持する）支持材を保持する保持部を有し、構造材の上フランジ部と保持部材の取付部は係止と固定の２つの手段によって取り付けられていることを特徴とする取付構造、及び該取付構造を含む外装構造に関するものである。
【０００５】
【発明の実施の形態】
図１，２に示す外装構造は、本発明の取付構造の一実施例を含むものであり、その要部（３倍拡大図）は図３に示す通りである。以下に、本発明の取付構造に用いる構造材１及び保持部材２について、更に外装構造に用いたその他の部材である外装材５、カバー材６、断熱材７、機能性ボート８について説明する。
【０００６】
本発明に用いる構造材１は、上フランジ部１１と、そこから垂下する縦片部１２とを備える構成であり、図示実施例の構造材１は更に縦片部１２の下端に下フランジ部１３を備えている。
この構造材１は、複数の軽量型鋼を溶接やボルト締め等により一体に形成したものでも良いし、Ｃ型鋼等の軽量型鋼そのものを構造材として良いし、或いはアルミの押出成形体でも良いし、図１〜３の実施例のように亜鉛メッキ鋼板をロール成形したものでも良い。
【０００７】
上フランジ部１１は、図１〜３の実施例のように左右の何れか一方（内側か外側）に延出するものでも良いし、両方に延出するものでもよく、後述する保持部材２の固定箇所である。尚、構造材１を屋根の傾斜勾配に直交するように配設する態様において、左右の何れか一方のみに上フランジ部１１を延出させる場合には、軒側に上フランジ部１１が延出するように配設する。
【０００８】
縦片部１２は、図１〜３の実施例のように二重で隙間を有する構成としても良いし、単層板状に形成しても良い。そして、図示実施例のようにＬ型のアングル材３の縦片３１を縦片部１２の隙間に挿入して挟持状に固定し、これを横鋼材４などに固定しても良い。また、縦片部１２には開口部を形成しても良い。この開口部は楕円形、円形等どのような形状でも良く、適宜間隔で設ければ良い。この開口部は、Ｌ型のアングル材の取付孔として用いても良いし、図示しない天井材等、或いは天井材等を支持する受材、或いは受材を連結させる連結材などを取り付ける取付孔として用いても良い。或いは図示しない照明や太陽電池等の電気配線、その他の配線・配管などを通すようにしても良い。
【０００９】
本発明に用いる保持部材２は、屋根面等の外装面を構築する外装材５、或いは上部外装構造を支持するための支持材９を取り付け保持するための部材であって、働き幅方向（左右方向）において位置を規制するための係止部２１１を少なくとも１つ以上備える取付部２１と、該取付部２１から上方へ延在する起立部２２と、外装材５又は支持材９が取り付けられる保持部（外装材保持部２３、支持材保持部２６）を有する構成であって、図示実施例の保持部材２は下方に位置する断熱金具２Ａと上方に位置する受金具２Ｂの複数部材をボルトの締着により組み合わせる構成であるが、溶接等の接着によって組み合わせるものでも良いし、一部材からなるものでも良い。
断熱金具２Ａは、取付部２１と起立部２２を備える構成であり、受金具２Ｂは、外装材保持部２３を備える構成である。
【００１０】
図示実施例の断熱金具２Ａは、取付部２１と起立部２２を備える構成である。取付部２１に設ける係止部２１１は、図３（ｃ）に示すように垂下片に溝を設けた態様でも良いし、後述する図４に示すように取付部２１の一辺を裏面内側に折曲した態様でも良い。尚、図示実施例の取付部２１には、構造材１の縦片部１２に当接する垂下状の規制部２１２を形成したが、この規制部２１２は働き幅方向（左右方向）において係止部２１１と逆方向の位置規制を行うものであり、図では係止部２１１が取付部２１の右側方向へのずれを防止するのに対し、規制部２１２は左側方向へのずれを防止する。さらに係止部２１１は、係止、係合、嵌合等の如何なる態様であっても良く、例えば嵌合の例としては、後述する図５に示すように構造材１の上フランジ部１１の外側端に膨出部１１１を設けてその膨出部１１１と保持部材２の係止部２１１が弾性嵌合するようにしても良い。
起立部２２は、図示実施例では樹脂製の筒体とし、上方の外装材保持部２３側と下方の取付部２１側とを断熱するものとした。起立部２２の上端には受金具２Ｂと連結するためのボルト２２１が一体に取り付けられている。
【００１１】
図示実施例の受金具２Ｂは、外装材５が取り付けられる外装材保持部２３を備える構成である。
この受金具２Ｂは、後述する外装材５の寸法、所要強度等に応じて通常０．６乃至３．２ｍｍ程度のステンレス鋼板やメッキ鋼板等をプレス加工する等して成形され、図３（ｂ）に示すようにそれぞれ前後に左右対称形状に形成された受け部分２４が起立する断面Ｕ字状に成形されたピース材であり、施工に際しては底面部分２５を前記断熱金具２Ａと接合（ボルト２２１ナット２２２による締着）する。そして、受け部分２４の上端（第２被係合部２３２）及び左右側縁（第１被係合部２３１）には、外装材５と弾性係合（嵌合）する外装材保持部２３が設けられている。尚、外装材保持部２３は、外装材５が取り付けられるものであれば、使用する外装材５の形状等に応じてどのような形状としても良い。
【００１２】
図示実施例の外装材５は、１つの谷部（平面部５１）と、左右側縁に取付手段を有する成形部５２とを備える縦葺き折板であって、代表的には概ね０．４〜１．６ｍｍ程度の表面化粧鋼板、ステンレス鋼板、ラミネート鋼板、溶融亜鉛メッキ鋼板やガルバリウム鋼板等の防錆処理鋼板、特殊鋼及び非鉄金属、アルミ合金板、鉛板、亜鉛板、チタン合金板、銅板等の公知の金属素材をロール成形やプレス成形、その他の手段で所定の形状に成形される。尚、外装材５の左右側縁の成形部５２に設けられる取付手段は、前記第１被係合部２３１及び第２被係合部２３２にそれぞれ弾性係合する断面略く字状の第１係合部５２１及び断面Ｕ字状の第２係合部５２２であるが、これに限定されるものではなく、嵌合、ハゼ締め、ビス等の固定具による直止め等の公知の取付手段を備えていれば良い。即ち前記保持部材２にて保持されるものであれば形状等についても公知のどのようなものでも良く、例えば縦葺き、横葺き、折板等の屋根構造でも良いし、太陽電池パネル、緑化構造であっても良く、その構成は特に限定するものではない。
【００１３】
図示実施例のカバー材６は、前記外装材５と同様の素材からなり、左右側縁に外装材５に弾性嵌合するための取付手段が設けられている。
【００１４】
図示実施例の断熱材７は、非透水性材からなり、１以上の山部７１と、左右側縁に平坦部７２を備え、表面には、流れ方向に沿って複数の排水溝７２１が形成されており、端部に隣接する断熱材７と重合可能な重合部７２２及び被重合部７２３が設けられ、且つ重合部分内に排水用の空間部７２４が形成される構成である。この場合、排水溝７２１及び空間部７２４にて雨水を排水でき、断熱材７の裏面側（室内側）に雨水が至ることがない。また、同様に流れ方向の端縁にも、軒棟方向に隣接する断熱材７と重合可能な重合部７２５及び被重合部７２６を設けた。
そして、施工後の外装構造では、断熱材７の山部７１上には隣接する外装材５，５の側縁が、断熱材７，７の接続部分上には外装材５の谷部（平面部５１）が位置するように敷設する。
【００１５】
図示実施例の機能性ボート８は、室内側へマイナスイオンを放出するマイナスイオン発生機能並びに遠赤外線を放射する遠赤外線放射機能を建材に付与した構成である。この機能性ボード（マイナスイオン発生建材）８から発生するマイナスイオン及び遠赤外線は、室内側へ放出、放射される。
具体的にはアクリル酸の共重合エマルジョンを主成分とする水性塗料（元旦フューテック株式会社製フュアコートＦＸ）に、導電材として粉末状炭素繊維（東レ株式会社製トスカ）を、水性塗料１００重量部に対して１０重量部添加すると共に、ガーネット５ｗｔ％とジルコニウム、バリウム、ランタン、セリウム、ネオジウム等の鉱物焼成による酸化物からなる励起材９５ｗｔ％からなる混合微粉末（平均粒径５μｍ）を１０重量部添加して充分に撹拌混合して作製した液状組成物を、元旦ビューティ工業株式会社社製元旦ボード４０ｍｍ（木毛セメント板）にコーティングし、充分に乾燥させた。
その他にも機能性ボード８としては、断熱、吸音、遮音、防耐火から選ばれる１つ以上の特性を有する板状成形体であって、グラスウール、発泡樹脂等からなるマット状又はボード状等の断熱材、吸音材、防火材、或いは各種素材を用いることができ、単一材質からなるものでも、異材質の積層体であっても良く、さらには硬質でも軟質であっても良く、その厚みについても適宜設定すればよい。
尚、図示しないが、機能性ボード８の下面（室内側）又は上面（屋根側）、或いはその両方に、受け材として複数のワイヤー、Ｔジョイナー、鋼棒材、フラットバー等を適宜間隔で配置したり、金網、パンチングメタル、メッシュ（落下防止用ネット）等を配設したり、これらを組み合わせて用いることにより、機能性ボード８やその上に配される断熱材７の撓み、変形、落下等を防止するようにしても良い。
【００１６】
このような各部材から構成される図１，２の外装構造は、適宜間隔で構造材１を横鋼材４上に配設した後、構造材１の下フランジ部１３に機能性ボード８を取り付け、続いて構造材１の上フランジ部１１に断熱金具２Ａの取付部２１を固定する。その際、取付部２１には係止部２１１及び規制部２１２が設けられているので、取付部２１を傾斜させた状態でまず上フランジ部１１の先端に係止部２１１を係合させ、次に係止部２１１を支点として回動させて規制部２１２を縦片部１２に当接させることができ、係止部２１１及び規制部２１２で嵌合状に取り付けられる。そのため、上フランジ部１１に対して適正な位置に取付部２１を位置規制することができる。この状態で溶接等の接着、或いは取付部２１に設けた取付孔２１３の上方からビス等を挿入して止着することにより、取付部２１を適性位置にて上フランジ部１１に一体に固定することができる。その後、断熱材７を配し、断熱金具２Ａに受金具２Ｂを取り付け（ボルト２２１ナット２２２による締着）、さらに外装材５を敷設し、カバー材６を取り付けて施工される。
【００１７】
このように本発明の取付構造及び外装構造は、保持部材２の構造材１への固定が係止部２１１による係止（位置規制）を伴うものであるため、現場での作業手間が著しく削減され、作業性が極めて良好である。特に図示実施例では係止部２１１に加えて規制部２１２をも設けて嵌合状に取り付けられるようにしたので、ボルト等による締着や溶接等の接着により固定する作業時に左右方向（働き幅方向）にずれ動いたりすることがなく適切に作業を行うことができる。
また、図示実施例では起立部２２が上方の外装材保持部２３側と下方の取付部２１側とを断熱するものとしたので、外装面からの熱を室内側へ伝熱することがなく、断熱性が高く、夏季の冷房効率、冬季の暖房効率を低下させることがないものである。
【００１８】
また、図示実施例の外装構造は、外装材５の側縁と断熱材７の側縁を鉛直方向のずれた位置に配して敷設したため、外装材の側縁からの侵入水が断熱材７の側縁に至ることがなく、断熱材７の裏側へ回り込むことがない。また、外装材５を２重に構築していないので、経済的にも優れている。
【００１９】
図４、図５に示す保持部材２は、取付部２１の構成が異なる以外は、前記図１〜３の実施例と全く同様である。
【００２０】
図４における取付部２１には、取付部２１の一辺（図面左側）を裏面内側に折曲した態様の係止部２１１が設けられ、この係止部２１１と規制部２１２とで弾性嵌合状に上フランジ部１１に取り付けられる。この取付部２１の上フランジ部１１への取り付けは、前記図１〜３の実施例と同様に行っても良いし、或いは先に規制部２１２を縦片部１２に当接させ、その状態で係止部２１１を弾性に抗して広げて上フランジ部１１の先端に係合させるようにしても良い。尚、規制部２１２の縦片部１２への当接は、面で接触するものでも、線や点で部分的に接触するものでも良く、弾性力によるものでも良い。
【００２１】
図５は、構造材１の上フランジ部１１の外側端に膨出部（被係合部）１１１を設け、その膨出部１１１と係合（弾性嵌合）する空部を有するような係止部兼規制部２１１（２１２）を形成した。この取付部２１の上フランジ部１１への取り付けは、取付部２１を上フランジ部１１の先端側から略水平状にスライドさせるだけで良い。尚、膨出部１１１に代えて窪み状の被係合部を設けても良く、また上フランジ部１１の外側端に限定するものではなく、例えば上フランジ部１１の裏面の途中に設けても良い。それに応じて係止部兼規制部２１１（２１２）も被係合部１１１と係合可能であれば形状は限定するものでなく、凹凸の係合関係であっても、凹又は凸に対して係合する爪（返し片）状などであっても良い。また係合は弾性力によるものでも良い。
【００２２】
図６は、保持部材２が図示しない上部外装構造を支持する支持材９を取り付け保持する支持材保持部２６を備える構成であって、それ以外の構成は、前記図１〜３の実施例とほぼ同様であるから図面に同一符号を付して説明を省略する。
即ちこの図示実施例の保持部材２は、前記構成の断熱金具２Ａの上部に受金具２Ｂに代えて取付金具２Ｃを組み合わせ、さらに支持材９の取り付けに際して定着用金具２Ｄを組み合わせる構成であり、これら取付金具２Ｃ及び定着用金具２Ｄにより支持材９を保持する支持材保持部２６が形成される。
図示実施例の支持材９は、断面略ハット型で、内側へ湾曲した係合部９１及び底片部９２が左右に設けられる形状であり、この支持材９が支持する上部外装構造はどのような構成でも良い。
また、取付金具２Ｃは、前後に左右対称形状に形成された起立部分２７が対向すると共に底面部分２８から左右に延在して左右側縁に折返し部２９が形成されたピース材であり、施工に際しては底面部分２８を断熱金具２Ａと接合（ボルト２２１ナット２２２による締着）する。
定着用金具２Ｄは、断面略ハット型の支持材９を配した状態で取り付けるものであり、前後方向にスライドさせて左右端が係合部９１の外側及び折返し部２９に噛合状に取り付けられる。
そして、起立部分２７の左右に形成された被係合部に、支持材９の係合部９１（の内側）が弾性的に嵌合し、支持材９の底片部９２を取付金具２Ｃ（の左右の延在片）と定着用金具２Ｄの間に挟み込むように取り付ける。したがって、支持材保持部２６とは、具体的にはこれら被係合部及び取付金具２Ｃと定着用金具２Ｄの間を指す。
また、図示実施例では２種の断熱材７Ａ，７Ｂが用いられ、上面側に配される断熱材７Ａが、前記図１〜３の実施例における非透水性材からなる断熱材７に相当する。即ち表面には、流れ方向に沿って複数の排水溝７３が形成され、端部に隣接する断熱材７Ａと重合可能な重合部７４及び被重合部７５が設けられ、且つそれぞれの先端には凸部７４１，７５１が設けられ、重合部分内に排水用の空間部７６が形成される構成である。そして、排水溝７３及び空間部７６にて雨水を排水でき、断熱材７Ａの裏面側（室内側）に雨水が至ることがない。このような断熱材７Ａにて形成される下部外装構造に対し、図示しないが上部外装構造を支持材９に取り付け支持させると、二重の外装構造となり、二重の外装構造が構築されることとなり、雨仕舞性や耐久性に優れたものとなる。
【００２３】
以上本発明を図面の実施の形態に基づいて説明したが、本発明は前記実施の形態に限定されるものではなく、特許請求の範囲に記載の構成を変更しない限りどのようにでも実施することができる。
【００２４】
【発明の効果】
以上説明したように本発明の取付構造及び外装構造は、保持部材の係止部を構造材に係止させるので、現場での作業工程が大幅に削減され、作業性が極めて良好である。即ち保持部材をボルト等による締着によって固定する場合には従来のように位置調整をしながら締着具を構造材の裏面に位置させる必要がなく、締着具を保持部材の取付部上から締着することができ、また保持部材を溶接等による接着によって固定する場合にも従来のように墨出しなどを行う必要がなく、適正な位置で固定することができ、外装材の組み付け不良を起こす虞もない。
【００２５】
保持部材が、構造材の縦片部に当接する規制部を有する場合や、構造材に被係合部を設けて該被係合部と係合する係止部兼規制部を保持部材に設けた場合には、係止部のみで係止させる場合に比べてより安定に位置規制することができ、左右方向の動きが規制され、固定作業時に働き幅方向にずれることがなく、適切に作業を行うことができる。

However, when the holding member is fixed to the structural material by fastening with bolts or the like, it is necessary to provide a hole for the fastener such as a bolt in the structural material in advance, and the fastener is formed of the structural material. Since it was located on the back surface (the lower surface side of the flange), the workability was extremely poor.
In addition, when the holding member is fixed to the structural material by welding, more specifically, blacking is performed on a fixing portion of the structural material, and the holding member is welded and fixed to the blackout line. If a shift occurs with respect to the blackout line at the time, the position shifts and the working width changes, and as a result, there has been a problem that a failure in assembling the exterior material occurs.
