【０００８】
【発明の実施の形態】
以下、本発明を好ましい実施形態に基づいて詳細に説明する。
図１は、本発明の天井板取付金物の一実施形態としての天井板取付金物１を示す斜視図である。図２及び図３は、図１の天井板取付金物の使用状態を示す側面図及び斜視図である。
本実施形態の天井板取付金物１は、図１〜図３に示すように、幅方向に連結される２枚の天井板２，３を、それらの連結部５において、天井板取付用の水平材としての野縁４に固定するものである。図３中の符号４１，４２は、平行に複数本配される野縁（一本のみ図示）４の各端部を受ける野縁掛け及び該野縁掛けと梁等の構造材との間を連結する連結材である。
【０００９】
本実施形態の天井板取付金物１は、図１及び図２に示すように、野縁４に当接する野縁当接部（水平材当接部）１３と、該野縁４の側面に対して垂直に配される一対の支持板部１４と、両支持板部１４の下端部に各支持板部に対して垂直に設けられた係止部１５とを有している。
野縁当接部１３は、野縁４の上面に当接される矩形状の天板部１１と、該天板部１１の両側に該天板部に対して垂直に設けられ、野縁４の対向する一対の側面にそれぞれ当接される側板部１２とからなる。支持板部１４は、各側板部１２の下端部から中央部にかけての一側縁部に、該側板部１２に対して垂直に設けられている。
【００１０】
天井板取付金物１には、目地幅保持手段１６が設けられている。目地幅保持手段１６は、隣接する２枚の天井板２，３の連結部に、該目地幅保持手段１６に応じた幅の目地６が形成されるようにするものである。
本実施形態における目地幅保持手段１６は、一対の上記支持板部１４それぞれから各支持板部１４に対して垂直方向に所定の距離離間させた位置に設けた目地幅保持片１６である。本実施形態における目地幅保持片１６は、矩形状で板状の小片であり、各側板部１２における、支持板部１４が設けられた一側縁部に対向する他側縁部に、該側板部１２と垂直に且つ支持板部１４と平行に形成されている。目地幅保持手段１６に応じた幅は、支持板部１４と目地幅保持片１６との間の距離Ｌに応じた幅（距離Ｌに応じて定まる幅）である。
【００１１】
図２〜図５には、上述した天井板取付金物１を、天井板同士の各連結部に用いて構築した天井板の取付構造又は天井（一部）が示されている。
具体的には、側端面２２に断面コ字状の嵌合溝２３を有する受け材２１が裏面の長手方向の一側部に固定され、側端面３２に断面コ字状の嵌合凸条３３を有する受け材３１が他側部に固定された複数本の天井板２，３を、嵌合溝２３と嵌合凸条３３とを嵌合させながら、幅方向に連結して形成した天井板の取付構造又は天井が示されている。
これらの天井板の取付構造又は天井においては、互いに連結された２枚の天井板２，３は、上述した天井板取付金物１により、両者の連結部において野縁４に吊持固定されている。
具体的には、天井板取付金物１の係止部１５が、一方の天井板２の裏面に固定された受け材２１に係合して、該天井板２の一側部が受け材２１を介して野縁４に直接固定されている一方、そのように固定された天井板２の嵌合溝２３に、隣接する他方の天井板３に固定された受け材３１の嵌合凸条３３が嵌合して、該天井板３が一側部が野縁４に間接的に固定されている。
【００１２】
天井板２，３同士の連結には、天井板２，３同士を両側から相互に押し付けて、一方の天井板２の嵌合溝２３に他方の天井板３の嵌合凸条３３を嵌合させる。このとき、天井板取付金物１の支持板部１４が、図２に示すように、連結される２本の天井板２，３の一方の天井板２の受け材２１の側端面２２に当接すると共に、目地幅保持手段としての目地幅保持片１６が、他方の天井板２の受け材３１の側端面３２に当接する。そのため、嵌合溝２３と嵌合凸条３３とが途中まで嵌合した状態においてそれ以上の嵌合が妨げられる。これにより、嵌合溝２３の底面２３ａと嵌合凸条３３の先端面３３ａとの間に一定幅の隙間が形成され、天井板２，３の側端面間に支持板部１４と該目地幅保持片１６との間の距離Ｌに応じた幅の目地６が形成される。
支持板部１４と該目地幅保持片１６との間の距離Ｌは、形成させようとする目地６の幅に応じて適宜に決定されるが、本実施形態の金物においては、例えば距離Ｌを３〜８ｍｍとし、目地幅を６〜１１ｍｍとすることができる。
【００１３】
本実施形態の天井板取付金物１によれば、このように、天井板同士の連結部に、目地幅保持手段１６に応じた幅（目地幅保持手段を有しない天井板取付金物を用いた場合には形成されない幅）の目地６を形成することができる。
従って、複数本の天井板を連結した合計連結幅（目地幅を含む幅，以下、天井板の合計連結幅もいう）が、施工対象の天井の幅に適合する幅となるように、天井板同士間に形成される目地の幅（支持板部１４と目地幅保持片１６との間の距離に応じて決定される目地の幅）を設定することにより、天井板の幅詰め加工を不要とすることができる。
【００１４】
施工対象の天井の幅に適合する目地幅を形成させるためには、支持板部１４と目地幅保持片１６との間の距離をその目地幅に対応した距離にする必要がある。そのため、幅が等しい天井板を用いて幅の異なる天井を形成するには、図４に示すように、支持板部１４と目地幅保持片１６との間の距離が異なる複数種類の金物を用意しておき、施工対象の天井の幅との関係で最も適切な金物を選択して使用する。尚、図４（ａ）に示す天井板取付金物は、一方の天井板２の受け材２１の側端面２２と他方の天井板３の受け材３１の側端面３２との間に隙間を形成しないものであり、本発明の天井板取付金物の実施形態ではない。
【００１５】
図５は、同一幅の天井板Ｐ（天井板２，３と同一構成の天井板）を用いて天井幅の異なる３種類の天井を構築する場合の天井板の割付例を示すものである。
図５（ａ）は、柱間寸法（Ｗ１）２７３０ｍｍ、天井板働き幅寸法（Ｗ２，天井両端の廻縁７，７の外側面同士間の幅）２６５２ｍｍの６帖間の和室天井を形成する場合であり、天井板の合計連結幅が２６２５ｍｍ超２６５２ｍｍ未満であると、天井板の幅詰め加工の必要がない。この場合、例えば幅４３７ｍｍの６本の天井板を目地幅６ｍｍで連結すれば、天井板の合計連結幅が上記範囲内となり〔合計連結幅；２６５２ｍｍ（４３７ｍｍ×６＋６ｍｍ×５）〕、天井板の幅詰め加工の必要はない。各連結部に用いる金物１の前記距離Ｌは３ｍｍとする。
【００１６】
図５（ｂ）は、Ｗ１＝３６４０ｍｍ、Ｗ２＝３５５９ｍｍの８帖間の和室天井を形成する場合であり、天井板の合計連結幅が、３５３５ｍｍ超３５５９ｍｍ未満であると、天井板の幅詰め加工の必要がない。この場合にも、上記と同じ幅の天井板（幅４３７ｍｍ）を連結本数を８本、目地幅９ｍｍとして連結すれば、天井板の合計連結幅は上記範囲内となり〔合計連結幅；３５５９ｍｍ（４３７ｍｍ×８＋９ｍｍ×７）〕、天井板の幅詰め加工の必要はない。この場合、各連結部に用いる金物１の前記距離Ｌは６ｍｍとする。
【００１７】
図５（ｃ）は、Ｗ１＝４５５０ｍｍ、Ｗ２＝４４６９ｍｍの１０帖間の和室天井を形成する場合であり、天井板の合計連結幅が４４４５ｍｍ超４４６９ｍｍ未満であると、天井板の幅詰め加工の必要がない。この場合にも、上記と同じ幅の天井板（幅４３７ｍｍ）を連結本数を１０本、目地幅１１ｍｍとして連結すれば、天井板の合計連結幅は上記範囲内となり〔合計連結幅；４４６９ｍｍ（４３７ｍｍ×１０＋１１ｍｍ×９）〕、天井板の幅詰め加工の必要はない。この場合、各連結部に用いる金物１の前記距離Ｌは８ｍｍとする。
