Description

【０００１】
【発明の属する技術分野】
本発明は、住宅、特に工場で生産されるユニット住宅の天井に装着する空気調和機に関するものである。
【０００２】
【従来の技術】
従来の天井埋込形の空気調和機を図４に示す。同図において、まず、吊りボルト固定部材５１を建物ユニットの天井開口部５２に架設し、その後この吊りボルト固定部材５１に吊りボルト５３の上部をナット５４で挟持して固定し、さらに空気調和機本体５５の側面に設けられた吊り金具５６に前記の吊りボルト５３の下部をナット５７で挟持して固定することにより建物ユニットの天井５８の野縁５９間に空気調和機本体５５を装着していた。また、その後、空気調和機本体５５の下方に化粧グリル６０を装着していた。
【０００３】
【発明が解決しようとする課題】
このような従来の空気調和機の装着では、吊りボルト固定部材５１を天井５８の奥に架設したり、吊りボルト５３自体を調整しながら固定する必要があるので、空気調和機本体５５の天井５８への装着は、工場での建物ユニット製造工程では天井裏の構造が完成していないため行えず、現地で行うしかなかった。
【０００４】
また、吊りボルト５３や吊りボルト固定部材５１、また複数のナット５４、５７など多くの部品を取り付けるため、その取付工程が面倒であるばかりでなく、空気調和機本体５５の装着後のナット５７の調整による高さ調整が必要でさらに手間がかかっていた。
【０００５】
また、吊りボルト固定部材５１を空気調和機本体５５の上方に架設することが必要なため、天井懐寸法が小さい場合には空気調和機本体５５の装着が困難であった。
【０００６】
また、前述のように取付構造が複雑なため、空気調和機本体５５位置変更や空気調和機本体５５の買い換え時の取り替えなどの対応が全くできなかった。
【０００７】
また、吊りボルト５３があるため保護材などの取付が困難で、空気調和機本体５５装着後の住宅建築時に生ずるホコリや接着剤などからの汚れの保護ができなかった。
【０００８】
本発明は、このような従来の課題を解決するものであり、工場での空気調和機本体の装着を可能とし、簡単で施工性の良い空気調和機を提供することを目的とする。
【０００９】
【課題を解決するための手段】
上記課題を解決するために本発明は、空気調和機本体の吊り金具に連結固定する支持板を設け、支持板と天井の野縁を固定したものである。
【００１０】
【発明の実施の形態】
請求項１に記載の発明は、野縁を有する天井に矩形状の天井開口穴を設け、その天井開口穴に、長手方向両側面に複数の吊り金具を有した空気調和機本体を設け、その空気調和機本体の複数の吊り金具に連結固定する支持板を設け、支持板の両端を天井との高さが所定の高さとなるように下方に折り曲げて野縁固定部を形成し、この野縁固定部を野縁の天井開口側に面する側面に固定したものであって、吊り金具と支持板を直接固定しているから部品点数が少なくて取付工程も簡単であり、また支持板の天井高さに対する取付位置があらかじめ決まっているから空気調和機本体装着後の高さ調整が不要となる。また、空気調和機本体を取り外せば、天井開口穴から野縁固定部の固定を容易に解除でき、空気調和機の本体の将来的な位置変更に容易に対応できる。
【００１２】
請求項２に記載の発明は、野縁固定部の下端を天井裏面に接することにより、天井との位置決めを行うようにしたから、位置決めを容易に行うことができる。
【００１３】
請求項３に記載の発明は、空気調和機本体に保護袋を設けた後、吊り金具を連結固定する支持板を設けたから、保護袋が、建物ユニットの製造過程や施工現場でのホコリや汚れから空気調和機本体を保護する。
【００１４】
請求項４に記載の発明は、保護袋は、空気調和機本体を包装箱に入れて輸送するときに用いるものを兼用したので、余分な袋が必要でなくなる。
【００１５】
以下本発明の実施形態について図面を参照して説明する。
【００１６】
図１及び図２において、１は天井２内に矩形状天井開口穴３を設けて埋め込まれた長方体の空気調和機本体であり、４は空気調和機本体１の下方に取り付けられ、天井２の表面に露出した化粧パネルである。また、５は空気調和機本体１の長手方向の両側面に取り付けられたボルト貫通穴６を有する複数の吊り金具で、７は天井２を保持し、空気調和機本体１の長手方向平行に設けられた野縁である。また、８は支持板であり、９は座金付きの六角ボルトである。
【００１７】
前記支持板８の中央部分は、上部に開口したコの字形状の断面が空気調和機本体１の幅よりも大きく連続して吊り金具固定部１０が形成され、また、その両端は、野縁７に接する間隔で下方に折曲して野縁固定部１１が形成されている。また、吊り金具固定部１０には、吊り金具５に対応して複数の貫通穴１２とナット１３が設けられている。ナット１３は吊り金具固定部１０の上面に貫通穴１２と対応して溶接固定されている。野縁固定部１１には、固定穴１４が複数個設けられている。
【００１８】
このような構成において、空気調和機本体１を工場の建物ユニットに装着するには、まず、空気調和機本体１の複数の吊り金具５の上部に支持板８を連結するように設け、吊り金具５のボルト貫通穴６と支持板８のナット１３を重合させて下方より六角ボルト９を挿通させて吊り金具５と支持板８を固定する。そして、空気調和機本体１の他の側面においても同様に吊り金具５と支持板８を固定する。
【００１９】
次に、その支持板を連結した空気調和機本体１を天井開口穴３を設けた近傍の野縁７の間に臨ませて、支持板８の野縁固定部１１の下端を天井２の裏面に接して仮位置決めをする。空気調和機本体１の長手方向についても所定の位置とした後、野縁固定部１１の固定穴１４を介してネジ１５を野縁７の側面にねじ込んで空気調和機本体１を天井２に装着固定するればよい。
【００２０】
化粧グリル４の装着は、天井２の表面にクロス貼り等の後の作業となるため、現場での作業となる。
【００２１】
また、図３は、空気調和機本体１を、包装箱に挿入して輸送するときに使用するポリエチレン製の保護袋１６に入れた状態のまま支持板８を上記と同様に固定したものであるが、この場合においても空気調和機本体１の装着の方法は全く同様である。つまり、空気調和機本体１の吊り金具５と支持板８は保護袋が介在した固定状態となるが、六角ボルト９を締め付けるとき保護袋１６がネジ山で容易に熱溶解するため特殊な加工も必要ない。
【００２２】
以上のように、空気調和機本体１の吊り金具５の上部に吊り金具５を連結固定する支持板８を設け、支持板８の両端を野縁７と固定したから、部品点数が少なくて取付工程が簡単であり、また、支持板８の両端に野縁固定部１１を形成し、その下端を天井２の裏面に接して位置決めするから、空気調和機本体１の装着後の高さ調整が不要で、精度のよい寸法とすることができ、空気調和機本体１の工場の建物ユニット製造工程での装着が可能となる。
【００２３】
また、吊り金具５と支持板８が直接接触して固定され、空気調和機本体１の高さ以下で吊り構造が形成されるから、天井懐寸法が小さい場合でも空気調和機本体１の装着が可能である。
【００２４】
また、支持板８の吊り金具固定部１０の上面にナット１３が溶接固定されているから、吊り金具５を挟んで六角ボルト９を締め付ける際、ナット１３を固定する必要がなく、作業が簡単である。もちろん、現場施工後も、六角ボルト９の作業が同様に行えることは言うまでもない。
【００２５】
また、さらに、支持板８の両端を下方に折り曲げて野縁固定部１１を形成し、野縁固定部１１を野縁７の天井開口穴３側に面する側面に固定したから、空気調和機本体１を取り外せば、天井開口穴３から野縁固定部１１の固定の解除を容易にできるから、空気調和機本体１の将来的な位置変更に容易に対応できる。
【００２６】
また、空気調和機本体１に、包装箱に挿入して輸送するときに使用する全体を被う保護袋１６を設け、またそのままの状態で支持板８を設けたから、建物ユニットの製造工程や輸送運搬時、また施工現場で、空気調和機本体１をホコリや汚れから保護できるばかりでなく、余分な袋が不要であり、また工場において袋から取り出すという手間も必要ない。
【００２７】
【発明の効果】
上記実施形態から明らかなように、請求項１に記載の発明は、野縁を有する天井に矩形状の天井開口穴を設け、その天井開口穴に、長手方向両側面に複数の吊り金具を有した空気調和機本体を設け、その空気調和機本体の複数の吊り金具の上部に吊り金具を連結固定する支持板を設け、支持板の両端を天井との高さが所定の高さとなるように下方に折り曲げて野縁固定部を形成し、この野縁固定部を野縁の天井開口側に面する側面に固定したから、部品点数が少なくて取付工程も簡単であり、また空気調和機本体装着後の高さ調整が不要となり、空気調和機本体の工場の建物ユニット製造工程での装着を可能とすることができる。
【００２８】
また、空気調和機本体を取り外せば、天井開口穴から野縁固定部の固定を容易に解除でき、空気調和機本体の将来的な位置変更に容易に対応できる。
【００２９】
請求項２に記載の発明は、野縁固定部の下端を天井の裏面にあわせて位置決めできるので、空気調和機本体と天井の位置決めが容易に行うことができる。
【００３０】
請求項３および４に記載の発明は、空気調和機本体に、包装箱に入れて輸送するときなどに使用する全体を被う保護袋を設けた後、吊り金具を連結固定する支持板を設けたから、建物ユニットの製造工程や輸送運搬時、また施工現場で、空気調和機本体をホコリや汚れから保護できるばかりでなく、余分な袋が不要であり、また工場において袋から取り出すという手間も必要ない。
