Description

【０００１】
【発明の属する技術分野】
この発明は、外装材として用いられる胴差、破風、鼻隠、見切り材、コーナー材および外壁パネルのジョイント部目隠しモール材、内装材として用いられる回り縁および幅木、その他の建築用化粧板材の取付金具に関する。
【０００２】
【従来の技術】
上述のような建築用化粧板材を建物躯体に取り付けるために用いられる取付金具としては、図１３〜図１５に示すアルミ成形品の取付金具１００が知られている。図１３は、取付金具１００により建築用化粧板材５０が建物躯体５に取付けられた状態を示す図であり、図１４は取付金具１００の平面図であり、図１５は図１４中Ｘ−Ｘ’線矢視断面図である。
【０００３】
この取付金具１００は、図１４および図１５に示すように、矩形の基板部１０１の中央高さ位置より幾分下の位置において横方向に延在するフック部１０２が突出成形されている。基板部１０１の上端部中央には建物躯体５へのビス止めのためのビス穴１０９が形成されている。
【０００４】
建築用化粧板材５０は、窯業系材料で成形されているために比較的重いものである。そのため、図１３に示すように、建築用化粧板材５０の金具取付部５５は、建築用化粧板材５０の重量を十分に支持できるように建築用化粧板材５０の背面５１の長手方向（建築用化粧板材５０の正面または背面から見て横方向）に形成したフック溝５６を有している。
【０００５】
このフック溝５６は、背面５１から建築用化粧板材５の厚さ方向へ窪むように開口した入口溝部５７と、これに略直角に屈曲し連続して設けられる係止溝部５８とからなり、その屈曲角部に係合顎部５９が形成されている。
【０００６】
取付金具１００を化粧板材５０の金具取付部５５に取り付け固定する作業は、取付金具１００のフック部１０２を背面５１の係合顎部５９に係合させると共に、それらの問および両者の係合部分に接着剤６０を介在させ、その接着剤６０が硬化することによって本来は完了するものである。
【０００７】
接着剤６０の硬化後は化粧板材５０と一体となった取付金具１００を建物躯体５にビス止めして固定することになる。この建物躯体５への固定作業は、化粧板材５０から突出する取付金具１００のヘッダー部１０８に形成されたビス穴１０９を利用してビス止めを行っていた。
【０００８】
しかし、実際には接着剤６０が完全に硬化するまでには時間がかかるために、接着剤６０の完全硬化を待たずとも建物躯体５への固定作業を行なうことができるように、図１３に示すように、釘状の止め具であるタッカー６５を用いて取付金具１００を化粧板材５０へ仮止めし、接着剤６０が硬化するまでの不安定な状態を補って上述の固定作業を行っていた。
【０００９】
タッカー６５は、取付金具１００の基板部１０１の平坦部分から化粧板材５０の背面５１へ打ち付けられるが、アルミ製の取付金具１００は比較的柔らかいので、タッカー６５による打ち抜きが可能であり、タッカー６５による取付金具１００の化粧板材５０への仮止めは安定していて効果的であった。
【００１０】
【発明が解決しようとする課題】
しかし、上述したような従来の取付金具１００の金具取付部５５への固定作業では、接着剤６０が硬化する前にタッカー６５を使用するために、タッカー６５の打ち付け時の衝撃等で取付金具１００が化粧板材５０に対して位置ズレを起こすことがあった。
【００１１】
たとえば、化粧板材５０の高さ方向（縦方向）に取付金具１００の取付位置ががズレた場合は、化粧板材５０を長手方向に継足していくときに継目部分で段差が生じ、美観を損なう問題が生じる。
【００１２】
また、化粧板材５０の長手方向に取付金具１００の取付位置がズレた場合は、建物躯体５に対するビス止め位置が不揃いになり、極端に取付位置がズレた場合は、ビス止めの相手材となる間柱（通常は一定ピッチで間設される）等の下地材が無い位置に金具１００が位置するという問題が生じる。
【００１３】
また、そのような問題が生じるタッカー打ち自体が、工場に比べて比較的作業条件の悪い現場施工の作業および手間のかかる作業でもあり、またそのための道具（治具）も必要であった。一方、例えばステンレス鋼板製の取付金具を用いた場合には、タッカー打ちができない問題も生じていた。
【００１４】
この発明は、道具（治具）を用いることなく、簡単な操作で容易に安定した取付金具の化粧板材への取り付け固定を行なうことができ、また取付金具の化粧板材への固定時は勿論のこと、建物躯体に対するビス止めにおいても位置ズレが生じず、化粧板材の建物躯体への整った取り付け固定ができる耐久性に優れた建築用化粧板材の取付金具を提供することを目的としている。
【００１５】
【課題を解決するための手段】
この発明に基づいた建築用化粧板材の取付金具においては、背面の長手方向に沿って延在し、上記背面から厚さ方向へ窪んで開口した入口溝部と、上記背面と上記入口溝部との間に角部を有する係合顎部を形成するように上記入口溝部に対して略直交する方向へ屈曲するように上記入口溝部から連続する係止溝部とを有するフック溝を含む金具取付部を備える化粧板材を、建物躯体に取り付けるための建築用化粧板材の取付金具であって、この取付金具は、上記金具取付部に係止する係合部と、上記建物躯体に取り付け固定されるべく延設された板状部とを含み、上記係合部は、上記フック溝の上記入口溝部から挿入されて上記係止溝部へ差し込こまれるように、かつ、上記フック溝の上記係合顎部に嵌合されるように屈曲成形されたフック部と、上記取付金具を上記化粧板材の長手方向に対して交差する方向にスライド移動させることで、その嵌合後に上記係合顎部とは対向する側の上記入口溝部の溝壁面に対して弾性的に当接可能な舌状片とを含んでいる。
【００１６】
上記構成を採用することにより、取付金具を化粧板材に取付ける際に、取付金具を化粧板材の長手方向に対して交差する方向にスライド移動させることで、まずフック部が係合顎部に差し込まれ、その後、舌状片が溝部に入り込み、この溝部の溝壁面に対して舌状片が弾性的に当接する。したがって、取付金具を化粧板材に取付けた後には、舌状片とフック部とにより弾性的に取付金具が化粧板材のフック溝を含む金具取付部に係合する。
【００１７】
したがって、現場においても、道具（治具）を用いることなく取付金具を化粧板材に取付けることができる。また、取付金具の化粧板材への取付時には、取付金具を化粧板材の端面から長手方向にスライド挿入させる必要がないため、容易に取付けることができる。さらに、取付金具は弾性力を用いて化粧板材に取付けられているため、化粧板材から容易に外れることがない。
【００１８】
また、上記発明をより好ましい状態で実現するために、下記に示す構造が採用される。たとえば、上記舌状片は、上記フック部が設けられる上記取付金具と同じ側から、上記フック溝に向かうように設けられる。また、上記舌状片は、上記フック部が設けられる上記取付金具の対向する側から上記フック部に向かうように設けられる。
【００１９】
また、好ましくは、上記舌状片は、上記化粧板材と当接する位置に、上記取付金具の上記化粧板材への取付時に、上記取付金具の上記化粧板材の滑りを良くするための湾曲面を有する。このように、舌状片に湾曲面を設けることにより、取付金具の化粧板材への取付が容易に行なえるとともに、舌状片による化粧板材への傷つけを防止することが可能になる。
【００２０】
また、好ましくは、上記フック部は、上記化粧板材に噛込むことのできる噛込み爪を先端部に有する。このように、フック部に噛込み爪を設けておくことで、取付金具を化粧板材に取付けた後に、フック溝に沿って取付金具が移動することがなくなり、取付金具に位置決めを確実にするとともに、取付金具の化粧板材からの脱落を未然に防止することが可能になる。
【００２１】
また、この発明に基づいた建築用化粧板材の取付け構造においては、背面の長手方向に沿って延在し、上記背面から厚さ方向へ窪んで開口した入口溝部と、上記背面と上記入口溝部との間に角部を有する係合顎部を形成するように上記入口溝部に対して略直交する方向へ屈曲するように上記入口溝部から連続する係止溝部とを有するフック溝を含む金具取付部を備える化粧板材を、建物躯体に取り付けるための建築用化粧板材の取付金具を用いた建築用化粧板材の取付け構造であって、当該取付金具は、上記金具取付部に係止する係合部と、上記建物躯体に取り付け固定されるべく延設された板状部とを含み、上記係合部は、上記フック溝の上記入口溝部から挿入されて上記係止溝部へ差し込こまれるように、かつ、上記フック溝の上記係合顎部に嵌合されるように屈曲成形されたフック部と、上記取付金具を上記化粧板材の長手方向に対して交差する方向にスライド移動させることで、上記係合顎部とは対向する側の上記入口溝部の溝壁面に対して弾性的に当接可能な舌状片とを含んでいる。
【００２２】
上記構造を採用することによっても、道具（治具）を用いることなく取付金具を化粧板材に取付けることができる。また、取付金具の化粧板材への取付時には、取付金具を化粧板材の端面から長手方向にスライド挿入させる必要がないため、容易に取付けることができる。さらに、取付金具は弾性力を用いて化粧板材に取付けられているため、化粧板材から容易に外れることがない。
【００２３】
【発明の実施の形態】
以下、この発明に基づいた各実施の形態における建築用化粧板材の取付金具の構造について、図を参照しながら説明する。
【００２４】
（実施の形態１）
まず、図１〜図５を参照して、この発明に基づいた実施の形態１における建築用化粧板材の取付金具１０Ａの構造について説明する。なお、図１は、この実施の形態における取付金具１０Ａを化粧板材５０に取付けた状態を示す部分断面図である。また、図２は取付金具１０Ａの構造を示す平面図であり、図３は図２中Ｘ−Ｘ’線矢視断面図であり、図４は図２中Ｙ−Ｙ’線矢視断面図であり、図５は図４中Ｃで囲まれた領域の拡大図である。
【００２５】
この取付金具１０Ａは、耐久性に優れた矩形ステンレス鋼板の基板１１をプレス機械で金型を使用して打ち抜き成形されている。この取付金具１０Ａは、たとえば外壁の胴差として用いられる化粧板材５０を、外壁に取付けるのに使用されるものである。ステンレス鋼板は、耐久性に優れ、雨水等の水の侵入が有っても錆の発生か無く、外壁や化粧板材５０を錆で汚すことが無い。
【００２６】
図１および図２を参照して、この取付金具１０Ａは、化粧板材５０の背面５１に設けられた取付部５５に対して係合部１２において係止され、また建物躯体に対して板状部１８においてビス止めされるものである。
【００２７】
他方、化粧板材５０は、従来技術で説明したものと同じもので、上下にほぼ対称な断面形状を有した窯業系材料の押出し成形品であり、その金具取付部５５が、背面５１の上下各端縁部に長手方向に沿って形成されたフック溝５６によって溝成されている。
【００２８】
このフック溝５６は、背面５１に板材の厚さ方向へ窪む状態で開口した幅広な入口溝部５７と、これに直交する方向へ屈曲されて入口溝部５７から連続する係止溝部５８とを有している。入口溝部５７と係止溝部５８との間の角部には係合顎部５９が形成されて略Ｌ字状の横断面形状となっている。
【００２９】
図２〜図５に示すように、取付金具１０Ａは、その係合部１２を矩形のステンレス基板１１のほぼ下半分において、その横方向に並んで上向きに屈曲成形され、溝上壁面５７Ｂに沿う一対の幅広のフック部１３，１３と、それら一対のフック部１３，１３間のそれらの打ち抜き残部において、フック部１３，１３の対向する側からフック部１３，１３に向かうように形成された舌状片１６Ａとを有している。
【００３０】
これらフック部１３，１３と舌状片１６Ａとの配列は、打ち抜きプレス加工時の切粉や切屑の発生量を最少限に留める。各フック部１３は、その高さ方向に沿う中心線に沿って補強リブ１４が一体にプレス成形されるとともに、図５に拡大して示されるように、フック部１３の外側部先端に噛込み爪１５が切り込み形成されている。
【００３１】
また、取付金具１０Ａは、図４に示すように、化粧板材５０の上下各端縁から外側へ出るように延設された板状部１８に、ビスＢを挿入できるビス穴１９が形成されている。ビスＢには、皿頭・セレーシヨン付きリーマ・セルフドリルビスが使用できる。
【００３２】
さらに、舌状片１６Ａは、化粧板材５０の裏面５１および溝下壁面５７Ａと当接する位置に、取付金具１０Ａの化粧板材５０への取付時に、取付金具１０Ａの化粧板材５０に対する滑りを良くするための湾曲面１６ａを有する。このように、舌状片１６Ａに湾曲面１６ａを設けることにより、取付金具１０Ａの化粧板材５０への取付が容易に行なえるとともに、舌状片１６Ａによる化粧板材５０への傷つけを防止することが可能になる
次に、図６および図７を参照して、上述のように構成された取付金具１０Ａを化粧板材５０の取付部５５へ固定する作業について説明する。まず、図６を参照して、取付金具１０Ａのフック部１３を入口溝部５７へ挿入する。このとき、舌状片１６Ａの湾曲面１６ａは、化粧板材１０の裏面５１に当接するため、取付金具１０Ａは、図６に示すように湾曲した状態となる。
【００３３】
次に、図７を参照して、図６に示す状態を維持させたまま、取付金具１０Ａを図中矢印Ａで示す方向（化粧板材５０の長手方向に対して交差する方向）にスライドさせる。これにより、係合部１２のフック部１３は、フック溝５６の係合顎部５９に嵌合されるとともに、舌状片１６Ａが入口溝部５７へ嵌まり込み、溝下壁面５７Ａと弾性的に当接する。
【００３４】
以上により、取付金具１０Ａを化粧板材５０に取付けた後には、舌状片１６Ａと係合部１２のフック部１３とにより弾性的に取付金具１０Ａが化粧板材５０のフック溝５６を含む金具取付部５５に係合する。
【００３５】
したがって、現場においても、道具（治具）を用いることなく取付金具１０Ａを化粧板材５０に取付けることができる。また、取付金具１０Ａの化粧板材５０への取付時には、取付金具１０Ａを化粧板材１０Ａの端面から長手方向にスライド挿入させる必要がないため、容易に取付けることができる。さらに、取付金具１０は弾性力を用いて化粧板材５０に取付けられているため、化粧板材５０から容易に外れることがない。
【００３６】
また、この取付金具１０Ａはステンレス鋼製なので、打ち抜き加工や曲げ加工が可能であるとともに十分な弾性力を発揮する。
【００３７】
さらに、フック部１３，１３は係合顎部５９に強固に嵌合されるが、それらフック部１３，１３に一体にプレス成形された補強リブ１４によってフック部１３，１３全体の弾性力が高められており、その強い弾性力で係止作用は更に強めらている。これによって、取付金具１０Ａの化粧板材５０に対する前後方向のガタつきは防止される。また、この強力な前後方向の係止作用に加えて、フック部１３，１３が入口溝部５７の溝上壁面５７Ｂへ当接され、一方では折り曲げられた舌状片１６Ａが溝下壁面５７Ａへ押圧されているために上下方向におけるガタつきおよび縦ズレも防止される。
【００３８】
さらに、上述の係止作用に加えて、フック部１３，１３は、その外瑞部先端に噛込み爪１５，１５を切り込み形成しているために係合顎部５９へ噛込み爪１５，１５が喚い込んでアンカー力を高めており、左右横方向におけるガタつきおよび横ズレも防止される。
【００３９】
このように、取付金具１０Ａは、ステンレス鋼板を使用しているために耐久性が大幅に改善され、現場での取り付けが手作業のみによる簡単な操作によって、安定、かつ、容易に行なうことが可能になる。
【００４０】
また取付金具１０Ａの化粧板材取付部５５への固定時はもちろんのこと、建物躯体に対するビス止め時においても位置ズレが生じず、建物躯体に対して化粧板材５０を整った奇麗な取付状態に固定することが可能になる。
【００４１】
（実施の形態２）
以下、この発明に基づいた実施の形態２における建築用化粧板材の取付金具１０Ｂの構造について、図８〜図１０を参照して説明する。図８は、取付金具１０Ｂの構造を示す平面図であり、図９は図８中Ｙ−Ｙ’線矢視断面図であり、図１０はこの実施の形態における取付金具１０Ｂを化粧板材５０に取付けた状態を示す部分断面図である。
【００４２】
この取付金具１０Ｂの上記実施の形態１における取付金具１０Ａとの相違点は、舌状片１６Ｂが、フック部１３が設けられる取付金具１０Ａと同じ側から、係止溝部５８の溝下壁面５７Ａに向かうように設けられる点にあり、また、舌状片１６Ｂはステンレス鋼板の基板１１をプレス機械で金型を使用して一体的に打ち抜き成形されている。その他の構造および材質は、上記実施の形態１における取付金具１０Ａと同じである。
【００４３】
上記構造によっても、上記実施の形態１における取付金具１０Ａと同様の作用が得られ、その結果、耐久性が大幅に改善され、現場での取り付けが手作業のみによる簡単な操作によって、安定、かつ、容易に行なうことが可能になる。
【００４４】
また取付金具１０Ｂの化粧板材取付部５５への固定時はもちろんのこと、建物躯体に対するビス止め時においても位置ズレが生じず、建物躯体に対して化粧板材５０を整った奇麗な取付状態に固定することが可能になる。
【００４５】
（実施の形態３）
以下、この発明に基づいた実施の形態３における建築用化粧板材の取付金具１０Ｃの構造について、図１１および図１２を参照して説明する。なお、図１１は、取付金具１０Ｃの構造を示す平面図であり、図１２は図１１中Ｙ−Ｙ’線矢視断面図である。
【００４６】
図１１および図１２を参照して、この取付金具１０Ｃの上記実施の形態２における取付金具１０Ｂとの相違点は、実施の形態２の場合、舌状片１６Ｂがステンレス鋼板の基板１１をプレス機械で金型を使用して一体的に打ち抜き成形されているが、本実施の形態における取付金具１０Ｃの舌状片１６Ｃは、ステンレス鋼板の基板１１とは異なる材料で形成されている。舌状片１６Ｃに用いられる材料としては、十分な弾性力を発揮する必要から、ばね鋼鋼材（ＪＩＳＧ４８０１）等を用いることが好ましい。このように、舌状片１６Ｃに十分な弾性力が必要とされる場合には、舌状片１６Ｃに基板１１とは異なる材料を用いて弾性力を補うことにより、上記実施の形態１および２と同等以上の作用効果を得ることが可能になる。
【００４７】
なお、上記各実施の形態はすべての点で例示であって制限的なものではないと考えられる。本発明の技術的範囲は上記した説明ではなくて特許請求の範囲によって画定され、また、特許請求の範囲と均等の意味および範囲内でのすべての変更が含まれることが意図される。
【００４８】
【発明の効果】
この発明に基づいた建築用化粧板材の取付金具によれば、現場においても、道具（治具）を用いることなく取付金具を容易に化粧板材に取付けることができる。また、取付金具の化粧板材への取付時には、取付金具を化粧板材の長手方向にスライドさせるようなことがないため、化粧板材を傷つけることもない。さらに、取付金具は弾性力を用いて化粧板材に取付けられているため、化粧板材から容易に外れることがない。

BACKGROUND OF THE INVENTION
This invention is used to install body differences, breezes, nasal cover, parting materials used as exterior materials, corner materials and blindfold moldings for joints of outer wall panels, peripheral edges and baseboards used as interior materials, and other decorative decorative board materials. Related to brackets.
[0002]
[Prior art]
As a mounting bracket used for mounting the decorative sheet material for building as described above to a building frame, an aluminum molded product mounting bracket 100 shown in FIGS. 13 to 15 is known. 13 is a view showing a state in which the decorative decorative board material 50 is attached to the building housing 5 by the attachment fitting 100, FIG. 14 is a plan view of the attachment fitting 100, and FIG. FIG.
[0003]
As shown in FIGS. 14 and 15, the mounting bracket 100 has a hook portion 102 that protrudes in the lateral direction at a position slightly below the central height of the rectangular substrate portion 101. A screw hole 109 is formed at the center of the upper end portion of the substrate 101 for screwing the building housing 5.
[0004]
The decorative decorative board material 50 is relatively heavy because it is formed of a ceramic material. Therefore, as shown in FIG. 13, the metal fitting mounting portion 55 of the architectural decorative board material 50 has a longitudinal direction of the rear surface 51 of the architectural decorative board material 50 so as to sufficiently support the weight of the architectural decorative board material 50 (the architectural decorative plate). A hook groove 56 is formed in the lateral direction as viewed from the front or back of the plate member 50.
[0005]
The hook groove 56 is composed of an inlet groove portion 57 that is open from the back surface 51 so as to be recessed in the thickness direction of the architectural decorative board material 5, and a locking groove portion 58 that is bent substantially at right angles thereto and is continuously provided. Engagement jaws 59 are formed at the corners.
[0006]
The operation of attaching and fixing the mounting bracket 100 to the bracket mounting portion 55 of the decorative plate material 50 involves engaging the hook portion 102 of the mounting bracket 100 with the engaging jaw portion 59 of the back surface 51, and those questions and the engaging portions thereof. The adhesive 60 is interposed between the two and the adhesive 60 is cured.
[0007]
After the adhesive 60 is cured, the mounting bracket 100 integrated with the decorative board material 50 is fixed to the building housing 5 with screws. The fixing work to the building housing 5 is screwed using a screw hole 109 formed in the header portion 108 of the mounting bracket 100 protruding from the decorative board material 50.
[0008]
However, since it takes time until the adhesive 60 is completely cured in practice, the fixing operation to the building housing 5 can be performed without waiting for the adhesive 60 to be completely cured. As shown, the mounting fixture 100 is temporarily fixed to the decorative board material 50 using a tacker 65 which is a nail-shaped stopper, and the above-described fixing operation is performed to compensate for an unstable state until the adhesive 60 is cured. It was.
[0009]
The tucker 65 is struck from the flat portion of the substrate portion 101 of the mounting bracket 100 to the back surface 51 of the decorative plate member 50. However, since the aluminum mounting bracket 100 is relatively soft, it can be punched by the tucker 65. Temporary fixing of the mounting bracket 100 to the decorative board material 50 was stable and effective.
[0010]
[Problems to be solved by the invention]
However, in the fixing operation of the conventional mounting bracket 100 to the bracket mounting portion 55 as described above, the tacker 65 is used before the adhesive 60 is hardened. However, there was a case where the positional deviation with respect to the decorative board material 50 occurred.
[0011]
For example, when the mounting position of the mounting bracket 100 is shifted in the height direction (vertical direction) of the decorative board material 50, a step is generated at the joint portion when the decorative board material 50 is extended in the longitudinal direction, and the appearance is impaired. Problems arise.
[0012]
In addition, when the mounting position of the mounting bracket 100 is shifted in the longitudinal direction of the decorative board material 50, the screwing position with respect to the building housing 5 is not uniform, and when the mounting position is extremely shifted, it becomes a screwing counterpart material. There arises a problem that the metal fitting 100 is located at a position where there is no base material such as a stud (usually provided at a constant pitch).
[0013]
Further, the tucking itself that causes such a problem is an on-site construction work and a labor-intensive work with relatively poor working conditions compared to a factory, and a tool (jig) for that purpose is also necessary. On the other hand, for example, when a stainless steel mounting bracket is used, there is a problem that it cannot be tucked.
[0014]
According to the present invention, it is possible to easily fix and fix the mounting bracket to the decorative plate material by a simple operation without using a tool (jig), and of course when fixing the mounting bracket to the decorative plate material. In addition, an object of the present invention is to provide a mounting plate for a decorative decorative board material that is excellent in durability and can be mounted and fixed on a decorative structure of a decorative board material without any positional deviation even in screwing to the building casing.
[0015]
[Means for Solving the Problems]
In the mounting bracket for a decorative decorative board material according to the present invention, the inlet groove extending along the longitudinal direction of the back surface and opening in the thickness direction from the back surface, and the gap between the back surface and the inlet groove portion. And a fitting mounting portion including a hook groove having a locking groove portion that is continuous from the inlet groove portion so as to be bent in a direction substantially orthogonal to the inlet groove portion so as to form an engaging jaw portion having a corner portion. A mounting member for a decorative decorative plate material for attaching a decorative plate material to a building frame, wherein the mounting bracket is extended to be fixed to the building frame and an engaging portion that is locked to the bracket mounting unit. The engaging portion is inserted from the inlet groove portion of the hook groove and inserted into the locking groove portion, and is formed on the engaging jaw portion of the hook groove.
