【発明の属する技術分野】
本発明は、天井下地部分に横架されるチャンネル材の下側に、これと略直交して天井部材を支持するＴバー材を結合固定してなる天井部材支持構造に関するものである。
【０００２】
【従来の技術】
従来から、図１８に示す如く、天井下地部分に横架されるチャンネル材６の下側に、これと略直交して天井板19や照明器具24等の天井部材を支持する天井支持バー25を結合固定してなる天井部材支持構造は知られている（特開２００２−１６７８９８号公報参照）。ここでは、チャンネル材６と天井支持バー25とが結合具３を介して結合固定されている。結合具３は、図１９（ａ）に示す如く、間隔をあけて対向する対の縦板部１（一方が縦長）と、両縦板部１の上端縁を連続させる横板部２と、で縦断面が下方へ開口した略コ字型に形成されている。
【０００３】
又、結合具３の両縦板部１の下端縁には、内側へ折曲した係止片４が形成される共に、同両縦板部１の中程には下方へ開放された切欠状開口５が形成されている。そして、両切欠状開口５をチャンネル材６が貫通するよう、このチャンネル材６上には結合具３が跨がらせて載設される。又、図１９（ｂ）に示す如く、天井支持バー25は縦断面略Ｓ字型に形成され、上下段違いに係合片26ａ、26ｂを有しており、同下方の係合片26ｂと同じ高さに照明器具支持片27が形成され、この照明器具支持片27の下方反対側に天井板支持片28が形成されている。
【０００４】
この場合、図１８に示す如く、チャンネル材６の下側に天井支持バー25を配置し、この天井支持バー25の両係合片26ａ、26ｂを前記結合具３の両係止片４に係止し、両側に配設される同天井支持バー25の両照明器具支持片27間に照明器具24を架設固定し、両天井支持バー25の外側の天井板支持片28上に各々天井板19の端縁部分を載設する。そして、結合具３の横板部２に螺合されたビスを締め付けることで、チャンネル材６の下側面に天井支持バー25の上側面が押圧当接され、両者は強固に結合固定され、天井板19や照明器具24等の天井部材を天井支持バー25の両側で確実に支持することができる。

【発明が解決しようとする課題】
しかしながら、上記従来の技術にあっては、結合具３の横板部２に螺合されたビスを締め付けることにより、チャンネル材６の下側面に天井支持バー25の上側面を押圧当接させるものであるため、そのビス締め作業に手間取るという問題があった。又、結合具３の両側で対の係止片４は上下段違い状態で天井支持バー25を係止するものであるため、ビスを締め付けてもチャンネル材６の下側面と天井支持バー25の上側面とが安定状態で押圧当接されないという問題もあった。
【０００７】
そこで、本出願人は、図２０、２１に示す如く、チャンネル材６上に結合具３を跨がらせて載設し、チャンネル材６の下側にはこれと略直交する方向にして縦断面略逆Ｔ字型で天井部材を支持するＴバー材７を配置し、このＴバー材７の上端縁に沿って形成された凸リブ部８を、結合具３の同じ高さにある係止片４で係止する天井部材支持構造を考えた。
【０００８】
更に、この天井部材支持構造では、結合具３の横板部２とチャンネル材６の上側面との間にこのチャンネル材６と略直交する方向の軸を中心として回動する軸片部材９を保持させ、この軸片部材９の中程に下方へ若干突出した押圧屈曲部30を形成し、同軸片部材９を回動させてその押圧屈曲部30をチャンネル材６の上側面に摺接させこのチャンネル材６を下方へ押圧することにより、同チャンネル材６の下側面を前記Ｔバー材７の凸リブ部８上に当接させて、両者を結合固定するものである。
【０００９】
この場合、略コ字型の結合具３はそのコ字型をそのままチャンネル材６上に嵌め込むようにして載設されるものであり、それ故、これと略直交するＴバー材７を支持するために、両縦板部１の下部を捩じれ状に折曲させて向きを変えた支持受け片29が形成され、この両支持受け片29の下端縁各々に係止片４が配設されている。又、チャンネル材６はウェブ15と上下のフランジ16を有するＣ型チャンネル材で、Ｔバー材７は縦片部17と横片部18とを有しており、この横片部18の両側上に各々天井板19の端縁部分が載設される。
【００１０】
そして、軸片部材９は棒状材料を折曲して形成されたもので、結合具３の両縦板部１に形成された貫通孔に挿通されて回動自在に保持され、両縦板部１間の部分が若干下方へ屈曲突出されて同軸片部材９の中程には押圧屈曲部30が形成されている。又、軸片部材９の一端は結合具３の縦板部１より外方へ突出されて略Ｌ字状に折曲延設され、この略Ｌ字状のコーナー部31が係合される受け孔32を同縦板部１に形成している。
【００１１】
この場合、施工現場にて、軸片部材９を結合具３の両貫通孔に差し込み、同軸片部材９の略Ｌ字状に突出延設された部分をペンチ等の工具で掴んで同軸片部材９を回動させ、その押圧屈曲部30をチャンネル材６の上側面に摺接させ、このチャンネル材６を下方へ押圧することにより、同チャンネル材６の下側面をＴバー材７の凸リブ部８上に当接させて、両者を結合固定するものである。そして、この結合固定された状態を保持するために、軸片部材９の略Ｌ字状のコーナー部31を結合具３の受け孔32に係合させるものである。
【００１２】
したがって、この天井部材支持構造にあっては、天井板19等の天井部材を支持するのがＴバー材７であり、このＴバー材７の上端縁の凸リブ部８を係止する係止片４は結合具３に同じ高さで形成され、チャンネル材６の下側面と天井支持バー25の上側面とが比較的安定した状態で押圧当接される。しかしながら、この場合、結合具３の両係止片４は同じ高さであってもＴバー材７の長手方向で位置がずれて配設されるため、このＴバー材７には捩じれの力が加わって、同Ｔバー材７は確実に支持され難いものである。
【００１３】
又、この天井部材支持構造にあっては、上記従来の技術のように、ビス締め作業を必要とせず、軸片部材９を回動させて比較的簡単に、チャンネル材６の下側面をＴバー材７の凸リブ部８上に当接させ両者を結合固定することができる。しかしながら、この場合、施工現場にて軸片部材９を結合具３の両貫通孔に差し込むものであるため、同軸片部材９の押圧屈曲部30を大きく屈曲させて突出させることができず、押圧力は不十分であり、チャンネル材６とＴバー材７とを強固に結合固定し難いものである。
【００１４】
又、軸片部材９の一端を略Ｌ字状に突出延設してそのコーナー部31を結合具３の受け孔32に係合させるようになし、同軸片部材９の回動を阻止することで、チャンネル材６とＴバー材７との結合固定状態を確保しようとしているが、この場合、前記の如く、押圧屈曲部30の突出量が不十分であるため、施工中の振動や地震等の外力によって、同軸片部材９はその押圧屈曲部30による略垂直押圧状態を保持できず、戻り方向に回動して結合固定状態が解除され易いものである。
【００１５】
又、軸片部材９の略Ｌ字状に突出延設された部分をペンチ等の工具で掴んで同軸片部材９を回動させるものであるため、この軸片部材９は捩じれたり折曲したりして変形し易いものである。しかも、軸片部材９及び結合具３が複雑な構造となって、製作し難いものとなる。
【００１６】
本発明は、上記従来の技術における問題を悉く解決するために発明されたもので、その課題は、チャンネル材とＴバー材とが結合具を介し安定した状態で確実強固に結合固定され、この結合固定作業も簡単となる天井部材支持構造を提供することである。
【００１７】
【課題を解決するための手段】
本発明の請求項１記載の天井部材支持構造は、間隔をあけて対向する対の縦板部と両縦板部の上端縁を連続させる横板部とで縦断面が下方へ開口した略コ字型の結合具を形成し、この結合具の両縦板部の下端縁に内側へ折曲した係止片を形成すると共に同両縦板部の中程には下方へ開放された切欠状開口を形成し、この両切欠状開口を天井下地部分に横架されるチャンネル材が貫通するようこのチャンネル材上に同結合具を跨がらせて載設し、チャンネル材の下側にはこれと略直交する方向にして縦断面略逆Ｔ字型で天井部材を支持するＴバー材を配置し、このＴバー材の上端縁に沿って形成された凸リブ部を前記結合具の両側の係止片に挟持されるよう係止し、結合具の横板部とチャンネル材の上側面との間にはこのチャンネル材と略直交する方向の軸を中心として回動する軸片部材を保持させ、この軸片部材の中程に下方へ突出した押圧凸部を形成し、同軸片部材を回動させてその押圧凸部をチャンネル材の上側面に摺接させこのチャンネル材を下方へ押圧することにより、同チャンネル材の下側面を前記Ｔバー材の凸リブ部上に当接させて、両者を結合固定してなり、軸片部材の押圧凸部がその押圧摺接方向へ中立状態より少し超えた段階で、同軸片部材の回動が停止されるようになしたことを特徴とする。
【００１８】
したがって、この場合、Ｔバー材の上端縁の凸リブ部が結合具の両縦板部の相対向する両係止片で挟持されるように係止されるため、同Ｔバー材は安定状態で支持される。そして、この状態で、軸片部材を回動させることにより、この軸片部材の中程に下方へ突出するよう形成された押圧凸部がチャンネル材の上側面に摺接されてこのチャンネル材を下方へ押圧し、同チャンネル材の下側面はＴバー材の凸リブ部上にバランス良く当接され、両者が結合具を介して安定した状態で確実強固に結合固定される。
【００１９】
しかも、軸片部材は結合具の両縦板部間でその回動がある程度規制された状態で保持されるため、施工中の振動や地震等の外力によっても同軸片部材は戻り方向に回動し難く、その押圧凸部による略垂直押圧状態が保持され易くて、これによる結合固定状態も解除され難いものである。又、結合具及びこの結合具の両縦板部に略沿って保持される軸片部材は比較的簡単な構造となり、この軸片部材を回動させて容易に前記結合固定作業を行うことができる。また、軸片部材の押圧凸部がその押圧摺接方向へ中立状態（押圧凸部がチャンネル材の上側面に対して最も突っ張って押圧している状態）より少し超えた段階で、同軸片部材の回動が停止されるため、この停止状態で、同軸片部材は戻り方向へ回動することなく安定状態で保持され、さらに、軸片部材の回動が中立状態を少し超えて停止されることにより、その際にクリック感を生じ、作業者は結合固定されたことを体感的に確認することができる。
【００２０】
本発明の請求項２記載の天井部材支持構造は、上記請求項１記載の天井部材支持構造において、軸片部材を棒状材料で形成し、同軸片部材の中程を下方へ屈曲突出させて押圧凸部を形成したことを特徴とする。
【００２１】
したがって、この場合は特に、軸片部材が棒状材料で形成され、この軸片部材の中程を下方へ屈曲突出させて押圧凸部を簡単に形成することもでき、同軸片部材は押圧凸部と共に安価に製作されるものとなる。
【００２２】
本発明の請求項３記載の天井部材支持構造は、上記請求項１又は２記載の天井部材支持構造において、軸片部材の押圧凸部の両側部分を回動自在に保持する保持片を結合具の縦板部から内側へ突設したことを特徴とする。
【００２３】
したがって、この場合は特に、結合具の縦板部から内側へ突設される保持片で軸片部材の押圧凸部の両側部分が回動自在に保持されるため、この軸片部材を同結合具に予め保持させておいてその取り扱いを容易とすることができ、これにより、同軸片部材の紛失や結合具からの外れを防止することもでき、この軸片部材はスムーズに回動されるようにもなって、その押圧凸部がチャンネル材の上側面に対して確実に摺接されるようになる。
【００２４】
本発明の請求項４記載の天井部材支持構造は、上記請求項１〜３のいずれか一つに記載の天井部材支持構造において、結合具の両切欠状開口にチャンネル材が貫通されると共に両係止片にＴバー材の凸リブ部が係止された状態で、軸片部材の押圧凸部をその押圧摺接方向とは反対側に位置する結合具の縦板部の外方へと逃がす欠如開口を同縦板部の切欠状開口の上縁に連続させて形成したことを特徴とする。
【００２５】
したがって、この場合は特に、軸片部材が結合具の両縦板部間に保持された状態でも、一方の縦板部に形成された切欠状開口及びその上縁に連続して形成された欠如開口から同軸片部材の押圧凸部を外方へと逃がすことができ、この状態でチャンネル材とＴバー材との結合固定状態は解除されており、両者を相互に同結合具を介しスライド移動させて容易に位置調整することができる。
【００２６】
本発明の請求項５記載の天井部材支持構造は、上記請求項４記載の天井部材支持構造において、欠如開口の上縁から爪状片を外側下方へと垂下突設し、この爪状片を内側へと塑性変形させることにより、同爪状片で押圧凸部がその押圧摺接方向へと押されて軸片部材を回動させるようになしたことを特徴とする。
【００２７】
したがって、この場合は特に、上記欠如開口の上縁から外側下方へと垂下突設された爪状片を内側へと塑性変形させることにより、同爪状片で押圧凸部がその押圧摺接方向へと押されて軸片部材を確実に回動させることができ、この回動作業は外側から容易に行われるものとなる。しかも、塑性変形された爪状片によって、軸片部材の戻り方向への回動が確実に防止されるようになる。
【００２８】
本発明の請求項６記載の天井部材支持構造は、上記請求項５記載の天井部材支持構造において、爪状片を外側へと屈曲突出した縦断面略く字状に形成し、この爪状片を内側へと塑性変形させる段階で、同爪状片の下端部分がチャンネル材の上側面に摺接されるようになしたことを特徴とする。
【００２９】
したがって、この場合は特に、上記爪状片が外側へと屈曲突出した縦断面略く字状に形成され、この爪状片を内側へと塑性変形させる段階で、同爪状片の下端部分はチャンネル材の上側面に摺接されるため、この爪状片の下端部分が軸片部材の押圧凸部を確実に押すものとなる。又、その際、押圧凸部とチャンネル材の上側面との間に爪状片の下端部分の先端が入り込んで、同チャンネル材はより強固に下方へ押圧されるようにもなる。
【００３２】
本発明の請求項７記載の天井部材支持構造は、上記請求項１〜６のいずれか一つに記載の天井部材支持構造において、押圧凸部の押圧摺接方向に位置する結合具の縦板部の切欠状開口の上縁部分にて同縦板部より外側へ屈曲突出した当止片部を形成し、この当止片部の内側面に押圧凸部が当止されることで軸片部材の回動が停止されるようになしたことを特徴とする。
【００３３】
したがって、この場合は特に、結合具の縦板部の切欠状開口の上縁部分にて同縦板部より外側へ屈曲突出した当止片部が形成され、この当止片部の内側面に押圧凸部が当止されることで、上記中立状態を少し超えた段階にある軸片部材の回動が停止されるため、同軸片部材はその戻り方向への回動が確実に防止されてより安定した状態で保持される。
【００３４】
【発明の実施の形態】
図１〜３は、本発明の前提となる天井部材支持構造として、参考的な実施形態（以下、「第一の実施形態」とする。）を示している。この実施形態の天井部材支持構造では、間隔をあけて対向する対の縦板部１と両縦板部１の上端縁を連続させる横板部２とで縦断面が下方へ開口した略コ字型の結合具３を形成し、この結合具３の両縦板部１の下端縁に内側へ折曲した係止片４を形成すると共に同両縦板部１の中程には下方へ開放された切欠状開口５を形成し、この両切欠状開口５を天井下地部分に横架されるチャンネル材６が貫通するようこのチャンネル材６上に同結合具３を跨がらせて載設している。
【００３５】
そして、チャンネル材６の下側にはこれと略直交する方向にして縦断面略逆Ｔ字型で天井部材を支持するＴバー材７を配置し、このＴバー材７の上端縁に沿って形成された凸リブ部８を、前記結合具３の両側の係止片４に挟持されるよう係止している。又、結合具３の横板部２とチャンネル材６の上側面との間には、このチャンネル材６と略直交する方向の軸を中心として回動する軸片部材９を保持させ、この軸片部材９の中程に下方へ突出した押圧凸部10を形成している。
【００３６】
この場合、軸片部材９を棒状材料で形成し、同軸片部材９の中程を下方へ屈曲突出させて押圧凸部10を形成している。前記保持された状態にある軸片部材９を回動させてその押圧凸部10をチャンネル材６の上側面に摺接させ、このチャンネル材６を下方へ押圧することにより、同チャンネル材６の下側面を前記Ｔバー材７の凸リブ部８上に当接させて、両者を結合固定している。
【００３７】
以下、この実施形態の天井部材支持構造を、より具体的に説明する。結合具３は矩形の金属板に打ち抜き折曲加工を施して形成されたもので、両縦板部１の間隔寸法が後記軸片部材９となる棒状材料の線径寸法の１．５〜３．０倍程度の巾狭となる略コ字型に形成されている。結合具３の両縦板部１には両者に連続して同じ大きさ形状に開口する縦長矩形状の切欠状開口５が形成されており、この切欠状開口５は下方へ開口されていてその両側に分割された両片の下端縁に略レ字状に折曲した係止片４が形成されている。又、切欠状開口５の開口巾寸法は、後記チャンネル材６の上下のフランジ16の巾寸法と略等しく形成されており、このチャンネル材６が同両切欠状開口５に嵌合するように貫通される。
【００３８】
チャンネル材６は天井下地部分に複数本並設されて横架されるもので、ウェブ15と上下のフランジ16を有する断面縦長の金属製Ｃ型チャンネル材である。そして、このチャンネル材６上には、前記結合具３がその両切欠状開口５を同チャンネル材６が貫通するよう跨がらせて係合載設される。結合具３の前記両側二対の係止片４には、縦断面略逆Ｔ字型のＴバー材７の凸リブ部８が両側から挟持されるようにして係止される。Ｔバー材７は金属製型材で、縦片部17とその下端で両側に突出する横片部18とでなり、同縦片部17の上端縁に沿って中空で断面略矩形状の凸リブ部８が形成されている。凸リブ部８の下面両側には凹所が形成されており、両凹所に係止片４の先端縁が入り込むようにして、この係止片４に同凸リブ部８は係止される。
【００３９】
結合具３の上部内側スペースには軸片部材９が収容保持されており、この軸片部材９は前記チャンネル材６と略直交する方向の軸を中心として回動される。軸片部材９は金属製の棒状材料に折曲加工を施して形成されたもので、その中程部分に下方へ略Ｖ字状に折曲突出した押圧凸部10が一体に形成されている。軸片部材９の両端は結合具３の両側へ突出しており、この結合具３の横板部２の下面に同軸片部材９の前記押圧凸部10の両側部分が当接し、この当接部分を中心軸として同軸片部材９は回動される。
【００４０】
又、軸片部材９はその押圧凸部10が略垂直状態から両側へ振れ動くように回動されるもので、この略垂直状態では同軸片部材９が前記結合具３の横板部２の下面とチャンネル材６の上側フランジ16の上面との間で突っ張った状態となって回動停止され保持される。そして、押圧凸部10が略垂直状態となる前記回動停止状態から両側いずれかへ軸片部材９が回動すると、チャンネル材６とＴバー材７との結合固定状態は解除され、両者を相互にずれ動かしてその位置調整を行うことができる。その際、軸片部材９の押圧凸部10が結合具３のいずれか一方の切欠状開口５の上部から縦板部１の外方へと突出することで、同軸片部材９は大きな角度に回動されて確実に解除された状態となる。
【００４１】
この実施形態の天井部材支持構造を施工するには、前記の如く、チャンネル材６とＴバー材７とを相互に位置調整した後、図３に示す如く、ペンチ等の工具Ｐで軸片部材９の押圧凸部10の部分を挟持して、この押圧凸部10が略垂直状態となるように同軸片部材９を回動させ、この軸片部材９を結合具３の横板部２の下面とチャンネル材６の上側フランジ16の上面との間で突っ張り状態にして回動停止させる。その際、ペンチ等の工具Ｐの先端部分が結合具３の両側の切欠状開口５の上部からこの結合具３の内部スペースに進入されて、軸片部材９は容易に回動され突っ張り状態で確実に停止される。
【００４２】
又、前記回動停止状態では、軸片部材９の押圧凸部10がチャンネル材６の上側フランジ16の上面に若干埋まり込むような状態で停止保持され、その際、同押圧凸部10の略Ｖ字状による弾性も作用してがたつきなく確実に回動停止され、同チャンネル材６とＴバー材７とは相互に確実強固に結合固定される。すなわち、前記の如く、軸片部材９を回動させると、その押圧凸部10がチャンネル材６の上側面に摺接されてこのチャンネル材６は下方へ押圧され、これにより、同チャンネル材６の下側面がＴバー材７の凸リブ部８上に当接されて、両者は確実強固に結合固定される。そして、図２に示す如く、Ｔバー材７の横片部18の両側上に各々天井板19の端縁部分が載設されて、この実施形態の天井部材支持構造の施工は完了する。
【００４３】
したがって、この実施形態の天井部材支持構造においては、Ｔバー材７の上端縁の凸リブ部８が結合具３の両縦板部１の相対向する両係止片４で挟持されるように係止されるため、同Ｔバー材７は安定した状態で支持される。そして、この状態で、軸片部材９を回動させることにより、この軸片部材９の中程に下方へ突出するよう形成された押圧凸部10がチャンネル材６の上側フランジ16の上側面に摺接されてこのチャンネル材６を下方へ押圧し、同チャンネル材６の下側フランジ16の下側面はＴバー材７の凸リブ部８上にバランス良く当接され、両者が結合具３を介して安定した状態で確実強固に結合固定される。
【００４４】
しかも、軸片部材９は結合具３の狭い間隔の両縦板部１間でその回動がある程度規制された状態で保持されるため、施工中の振動や地震等の外力によっても同軸片部材９は突っ張った状態から戻り方向に回動し難く、その押圧凸部10による略垂直押圧状態が保持され易くて、これによる結合固定状態も解除され難いものである。又、結合具３及びこの結合具３の両縦板部１に略沿って保持される軸片部材９の構造は、図２０、２１に示した従来例に比して簡単となり、この軸片部材９を回動させて容易に前記結合固定作業を行うことができる。
【００４５】
又、この実施形態の天井部材支持構造においては、軸片部材９が棒状材料でピンとして形成され、この軸片部材９の中程を下方へ屈曲突出させて押圧凸部10を簡単に形成することもでき、同軸片部材９を押圧凸部10と共に一つのピンとして安価に製作することができる。なお、この実施形態の天井部材支持構造においては、Ｔバー材７で支持される天井部材として天井板19を示したが、その他、照明器具等の天井部材を支持させてもよい。
【００４６】
図４は、本発明の前提となる天井部材支持構造として、参考的な実施形態（以下、「第二の実施形態」とする。）を示している。この実施形態の天井部材支持構造では、結合具３の横板部２が上方へ湾曲した断面形状となるように形成されていて、軸片部材９の同横板部２の下面に当接される部分が安定保持されるので、その押圧凸部10による略垂直押圧状態はより保持され易くなり、これによる結合固定状態が確実に保持されるものとなる。又、軸片部材９を前記当接部分を中心軸として回動させる際に、この中心軸は移動し難く、同軸片部材９をスムーズに回動させることができるようになる。なお、それ以外は、上記第一の実施形態と同様に構成され、上記第一の実施形態におけると同様の作用効果が奏される。
【００４７】
図５、６は、本発明の前提となる天井部材支持構造として、参考的な実施形態（以下、「第三の実施形態」とする。）を示している。この実施形態の天井部材支持構造では、結合具３の両切欠状開口５の上縁部分に外側下方へと垂下した爪状片13が突設されており、両爪状片13を両側からペンチ等の工具で挟持することで軸片部材９を回動させて、容易に同軸片部材９をその押圧凸部10の突っ張った略垂直押圧状態とすることができる。この場合、爪状片13は塑性変形されるもので、同爪状片13で押圧凸部10が両側から押されて軸片部材９は確実に回動され、この回動作業を両外側から容易に行うことができる。しかも、塑性変形された爪状片13によって、軸片部材９の戻り方向への回動が確実に防止されるようになる。なお、それ以外は、上記第二の実施形態と同様に構成され、上記第二の実施形態におけると同様の作用効果が奏される。
【００４８】
図７、８は、本発明の請求項１、２、４〜６に対応した第四の実施形態である天井部材支持構造を示している。この実施形態の天井部材支持構造では、結合具３の両切欠状開口５にチャンネル材６が貫通されると共に両係止片４にＴバー材７の凸リブ部８が係止された状態で、軸片部材９の押圧凸部10をその押圧摺接方向αとは反対側（図面向かって右側）に位置する結合具３の縦板部１の外方へと逃がす欠如開口12を、同縦板部１の切欠状開口５の上縁部分に連続開口させて形成している。
【００４９】
したがって、この場合、軸片部材９が結合具３の両縦板部１間に収容保持された状態でも、図７に示す如く、一方の縦板部１に形成された切欠状開口５及びその上縁に連続して形成された欠如開口12から同軸片部材９の押圧凸部10を外方へと逃がすことができ、この状態でチャンネル材６とＴバー材７との結合固定状態は解除されており、両者を相互に同結合具３を介し直交方向でスライド移動させて容易に位置調整することができる。
【００５０】
又、この実施形態の天井部材支持構造では、欠如開口12の上縁から爪状片13を外側下方へと垂下突設し、この爪状片13を内側へとペンチ等の工具で塑性変形させることにより、同爪状片13で押圧凸部10がその押圧摺接方向αへと押されて軸片部材９を回動させるようになしている。したがって、この場合、爪状片13を内側へと塑性変形させることにより、同爪状片13で押圧凸部10がその押圧摺接方向αへと押されて軸片部材９を確実に回動させることができ、この回動作業は外側から容易に行われる。しかも、図８に示す如く、塑性変形された爪状片13によって、軸片部材９の戻り方向への回動が確実に防止されるようになる。
【００５１】
又、この実施形態の天井部材支持構造では、爪状片13を外側へと屈曲突出した縦断面略く字状に形成し、この爪状片13を内側へと塑性変形させる段階で、同爪状片13の下端部分がチャンネル材６の上側フランジ16の上側面に摺接されるようになしている。したがって、この場合、爪状片13を内側へと塑性変形させる段階で、同爪状片13の下端部分はチャンネル材６の上側面に摺接されるため、この爪状片13の下端部分が軸片部材９の押圧凸部10を確実に押すものとなる。又、その際、押圧凸部10とチャンネル材６の上側面との間に爪状片13の下端部分の先端が入り込んで、同チャンネル材６はより強固に下方へ押圧されるようにもなる。
【００５２】
又、この実施形態の天井部材支持構造では、軸片部材９の押圧凸部10がその押圧摺接方向αへ中立状態より少し超えた段階で、この押圧凸部10は結合具３の一方の縦板部１の内側面に当止され、同軸片部材９の回動が停止される。したがって、この場合、軸片部材９の押圧凸部10がその押圧摺接方向αへ中立状態（押圧凸部10がチャンネル材６の上側面に対して最も突っ張って押圧している状態）より少し超えた段階で、同軸片部材９の回動は停止され、この停止状態で、同軸片部材９が戻り方向へ回動することなく安定状態で保持される。
【００５３】
しかも、その際、軸片部材９の略Ｖ字状に折曲した押圧凸部10の弾性が作用するため、この押圧凸部10がチャンネル材６の上側面に対して最も突っ張って押圧している状態から少しずれても、同軸片部材９の回動が停止された安定保持状態は確保される。更に、軸片部材９の回動が中立状態を少し超えて停止されることで、その際にクリック感を生じるため、このクリック感によって作業者は結合固定されたことを体感的に確認することができる。

【００５６】
又、この場合、結合具３の横板部２は平板状であっても、両起立片部20が両保持孔21に係合保持されることで、軸片部材９の回動の中心軸は移動し難く、この軸片部材９をスムーズに回動させることができ、しかも、同軸片部材９はその回動時にあっても安定した状態で保持され、押圧凸部10による略垂直押圧状態が保持され易く、これにより結合固定状態は確保されるものとなる。なお、それ以外は、上記第四の実施形態と同様に構成され、上記第四の実施形態におけると同様の作用効果が奏される。

【００５８】
したがって、この場合、結合具３の爪状片13とは反対側に位置する縦板部１の切欠状開口５の上縁部分において、同縦板部１より外側へ屈曲突出した当止片部14が形成されており、この当止片部14の内側面に押圧摺接方向αへ回動する押圧凸部10が当止されることで、上記第四の実施形態で説明したように、中立状態を少し超えた段階にある軸片部材９の回動が停止されるため、同軸片部材９はその戻り方向への回動が確実に防止されてより安定した状態で保持される。

【００６１】
したがって、この場合、結合具３の縦板部１から内側へ突設される両保持片11で軸片部材９の押圧凸部10の両側部分が回動自在に保持されるため、この軸片部材９を同結合具３に工場等で予め保持させ組み立てておいて、その取り扱いを容易とすることができる。これにより、部材の管理が容易となり、軸片部材９の紛失や結合具３からの外れを防止することもでき、この軸片部材９は安定保持されスムーズに回動されるようにもなって、その押圧凸部10がチャンネル材６の上側面に対して確実に摺接されるようになる。

BACKGROUND OF THE INVENTION
The present invention relates to a ceiling member support structure formed by coupling and fixing a T-bar material that supports a ceiling member substantially orthogonally to the lower side of a channel material that is horizontally mounted on a ceiling base portion.
[0002]
[Prior art]
Conventionally, as shown in FIG. 18, a ceiling support bar 25 that supports a ceiling member such as a ceiling plate 19 or a lighting fixture 24 is provided on the lower side of the channel material 6 laid horizontally on the ceiling base portion so as to be substantially orthogonal thereto. A ceiling member support structure formed by coupling and fixing is known (see Japanese Patent Application Laid-Open No. 2002-167898). Here, the channel member 6 and the ceiling support bar 25 are coupled and fixed via the coupler 3. As shown in FIG. 19 (a), the coupler 3 includes a pair of vertical plate portions 1 (one is vertically long) facing each other with a gap therebetween, and a horizontal plate portion 2 that makes the upper end edges of both vertical plate portions 1 continuous. The vertical cross section is formed in a substantially U-shape opening downward.
[0003]
In addition, a locking piece 4 bent inward is formed at the lower end edge of both vertical plate portions 1 of the coupler 3, and a notch shape opened downward in the middle of both vertical plate portions 1. An opening 5 is formed. And the coupling tool 3 is straddled and mounted on this channel material 6 so that the channel material 6 may penetrate the both notch-shaped opening 5. Further, as shown in FIG. 19 (b), the ceiling support bar 25 is formed in a substantially S-shaped longitudinal section, and has engaging pieces 26a, 26b in the upper and lower steps, which is the same as the engaging piece 26b below the same. A lighting fixture support piece 27 is formed at a height, and a ceiling plate support piece 28 is formed on the lower side opposite to the lighting fixture support piece 27.
[0004]
In this case, as shown in FIG. 18, a ceiling support bar 25 is disposed on the lower side of the channel member 6, and both engagement pieces 26 a and 26 b of the ceiling support bar 25 are engaged with both engagement pieces 4 of the coupler 3. The lighting fixture 24 is installed and fixed between the two lighting fixture support pieces 27 of the ceiling support bar 25 disposed on both sides, and the ceiling plate 19 is placed on the ceiling plate support piece 28 outside the two ceiling support bars 25. Place the edge part of. Then, by tightening a screw screwed into the horizontal plate portion 2 of the coupler 3, the upper side surface of the ceiling support bar 25 is pressed and brought into contact with the lower side surface of the channel member 6, and both are firmly coupled and fixed. The ceiling members such as the plate 19 and the lighting fixture 24 can be reliably supported on both sides of the ceiling support bar 25.

[0006]
[Problems to be solved by the invention]
However, in the above prior art, the upper surface of the ceiling support bar 25 is pressed against the lower surface of the channel member 6 by tightening a screw screwed into the horizontal plate portion 2 of the coupler 3. Therefore, there is a problem that it takes time to tighten the screws. Further, since the pair of locking pieces 4 on both sides of the coupler 3 are used to lock the ceiling support bar 25 in a vertically different state, the bottom surface of the channel material 6 and the top of the ceiling support bar 25 are secured even if the screws are tightened. There was also a problem that the side surface was not pressed against and contacted in a stable state.
[0007]
Therefore, as shown in FIGS. 20 and 21, the present applicant places the coupler 3 on the channel material 6 so as to straddle it, and forms a longitudinal section below the channel material 6 in a direction substantially orthogonal thereto. A T-bar member 7 that supports the ceiling member in a substantially inverted T-shape is disposed, and the convex rib portion 8 formed along the upper edge of the T-bar member 7 is locked at the same height of the coupler 3. A ceiling member support structure that is locked by the piece 4 was considered.
[0008]
Furthermore, in this ceiling member support structure, a shaft piece member 9 that rotates about an axis in a direction substantially orthogonal to the channel member 6 is provided between the horizontal plate portion 2 of the coupler 3 and the upper surface of the channel member 6. A pressing bent portion 30 that slightly protrudes downward is formed in the middle of the shaft piece member 9, and the coaxial piece member 9 is rotated so that the pressing bent portion 30 is slidably contacted with the upper surface of the channel member 6. By pressing the channel material 6 downward, the lower surface of the channel material 6 is brought into contact with the convex rib portion 8 of the T-bar material 7 so that both are coupled and fixed.
[0009]
In this case, the substantially U-shaped coupler 3 is mounted so that the U-shape is fitted on the channel material 6 as it is, and therefore, in order to support the T-bar material 7 substantially orthogonal thereto. In addition, a support receiving piece 29 is formed in which the lower portions of both vertical plate portions 1 are twisted and changed in direction, and a locking piece 4 is disposed at each lower end edge of the both support receiving pieces 29. . The channel material 6 is a C-type channel material having a web 15 and upper and lower flanges 16, and the T-bar material 7 has a vertical piece 17 and a horizontal piece 18, on both sides of the horizontal piece 18. The edge portions of the ceiling plate 19 are mounted on the respective panels.
[0010]
The shaft piece member 9 is formed by bending a rod-shaped material. The shaft piece member 9 is inserted into the through-holes formed in the both vertical plate portions 1 of the coupler 3 and is rotatably held. A portion between 1 is slightly bent downward and protruded, and a press bent portion 30 is formed in the middle of the coaxial piece member 9. Further, one end of the shaft piece member 9 protrudes outward from the vertical plate portion 1 of the coupler 3 and is bent and extended in a substantially L shape, and a receiving portion to which the substantially L-shaped corner portion 31 is engaged. A hole 32 is formed in the vertical plate portion 1.
[0011]
In this case, the shaft piece member 9 is inserted into both through-holes of the coupler 3 at the construction site, and the portion of the coaxial piece member 9 that protrudes and extends in a substantially L shape is grasped with a tool such as pliers. 9 is rotated, the pressing bent portion 30 is slidably contacted with the upper side surface of the channel material 6, and the channel material 6 is pressed downward, so that the lower side surface of the channel material 6 becomes the convex rib of the T-bar material 7. It is made to contact | abut on the part 8, and both are couple | bonded and fixed. Then, in order to maintain this coupled and fixed state, the substantially L-shaped corner portion 31 of the shaft piece member 9 is engaged with the receiving hole 32 of the coupling tool 3.
[0012]
Therefore, in this ceiling member support structure, the T-bar member 7 supports the ceiling member such as the ceiling plate 19 and the latch that locks the convex rib portion 8 at the upper edge of the T-bar member 7. The piece 4 is formed on the coupler 3 at the same height, and the lower surface of the channel member 6 and the upper surface of the ceiling support bar 25 are pressed against each other in a relatively stable state. However, in this case, since both the locking pieces 4 of the coupler 3 are arranged at the same height and shifted in the longitudinal direction of the T-bar material 7, the twisting force is applied to the T-bar material 7. In addition, the T-bar material 7 is hard to be reliably supported.
[0013]
Moreover, in this ceiling member support structure, unlike the prior art described above, a screw fastening operation is not required, and the lower surface of the channel member 6 is relatively easily moved by rotating the shaft piece member 9 to the T Both can be bonded and fixed on the convex rib portion 8 of the bar member 7. However, in this case, since the shaft piece member 9 is inserted into both through-holes of the coupler 3 at the construction site, the pressing bent portion 30 of the coaxial piece member 9 cannot be greatly bent and protruded. The pressure is insufficient and it is difficult to firmly bond and fix the channel material 6 and the T bar material 7.
[0014]
Further, one end of the shaft piece member 9 is extended and extended in a substantially L shape, and its corner portion 31 is engaged with the receiving hole 32 of the coupler 3 to prevent the rotation of the coaxial piece member 9. At this time, the channel member 6 and the T-bar member 7 are to be secured to each other. However, in this case, as described above, the protruding amount of the press-bending portion 30 is insufficient. Due to this external force, the coaxial piece member 9 cannot maintain the substantially vertical pressing state by the pressing bent portion 30, but can easily be released from the coupled and fixed state by rotating in the return direction.
[0015]
Further, since the coaxial piece member 9 is rotated by gripping a portion of the shaft piece member 9 extending and extending in a substantially L shape with a tool such as pliers, the shaft piece member 9 is twisted or bent. It is easy to deform. In addition, the shaft piece member 9 and the coupler 3 have a complicated structure and are difficult to manufacture.
[0016]
The present invention was invented in order to solve the above-described problems in the prior art, and the problem is that the channel material and the T-bar material are securely and securely coupled and fixed via a coupler. It is an object of the present invention to provide a ceiling member support structure that facilitates coupling and fixing.
[0017]
[Means for Solving the Problems]
  The ceiling member support structure according to claim 1 of the present invention has a substantially rectangular shape in which a vertical cross section is opened downward by a pair of vertical plate portions facing each other with a gap therebetween and a horizontal plate portion that connects the upper end edges of both vertical plate portions. A character-shaped coupler is formed, and a locking piece bent inward is formed at the lower edge of both vertical plate portions of the coupler, and a notch shape opened downward in the middle of the vertical plate portions. An opening is formed, and the both joints are placed over the channel material so that the channel material laid horizontally on the ceiling base portion passes through the both notched openings. A T-bar material that supports the ceiling member with a substantially inverted T-shaped longitudinal section is disposed in a direction substantially orthogonal to the T-bar material, and the convex rib portions formed along the upper edge of the T-bar material are disposed on both sides of the coupler. It is locked so as to be clamped by the locking piece, and the channel material is substantially orthogonal between the horizontal plate portion of the coupler and the upper surface of the channel material. The shaft piece member that rotates about the axis in the direction to be held is held, a pressing projection protruding downward is formed in the middle of the shaft piece member, the coaxial piece member is rotated, and the pressing projection is channeled By sliding the channel material against the upper surface of the material and pressing the channel material downward, the lower surface of the channel material is brought into contact with the convex rib portion of the T-bar material, and the two are bonded and fixed.The rotation of the coaxial piece member is stopped when the pressing convex portion of the shaft piece member slightly exceeds the neutral state in the pressing and sliding contact direction..
[0018]
Therefore, in this case, since the convex rib portion of the upper end edge of the T bar material is locked so as to be sandwiched between the opposing locking pieces of the two vertical plate portions of the coupler, the T bar material is in a stable state. Supported by In this state, by rotating the shaft piece member, the pressing convex portion formed so as to protrude downward in the middle of the shaft piece member is brought into sliding contact with the upper side surface of the channel material so that the channel material is Pressing downward, the lower surface of the channel material is brought into contact with the convex rib portion of the T-bar material in a well-balanced manner, and the two are reliably and firmly bonded and fixed via the coupler.
[0019]
  In addition, since the shaft piece member is held in a state where its rotation is regulated to some extent between the two vertical plate portions of the coupler, the coaxial piece member can be rotated in the return direction even by external force such as vibration or earthquake during construction. It is difficult to maintain the substantially vertical pressing state by the pressing convex portion, and it is difficult to release the coupled fixed state. Further, the coupling member and the shaft piece member held substantially along the vertical plate portions of the coupling device have a relatively simple structure, and the coupling and fixing operation can be easily performed by rotating the shaft piece member. it can.Further, when the pressing convex portion of the shaft piece member is slightly beyond the neutral state in the pressing and sliding contact direction (the pressing convex portion is most pressed against the upper surface of the channel material), the coaxial piece member In this stopped state, the coaxial piece member is held in a stable state without rotating in the return direction, and further, the rotation of the shaft piece member is stopped slightly beyond the neutral state. Thus, a click feeling is generated at that time, and the operator can visually confirm that the connection is fixed.
[0020]
The ceiling member support structure according to claim 2 of the present invention is the ceiling member support structure according to claim 1, wherein the shaft piece member is made of a rod-shaped material, and the middle of the coaxial piece member is bent and protrudes downward to be pressed. A convex portion is formed.
[0021]
Therefore, in this case, in particular, the shaft piece member is formed of a rod-shaped material, and the middle portion of the shaft piece member can be bent and protruded downward to easily form the pressing convex portion. And it will be manufactured at a low cost.
[0022]
The ceiling member support structure according to claim 3 of the present invention is the ceiling member support structure according to claim 1 or 2, wherein the holding pieces for rotatably holding the both side portions of the pressing convex portion of the shaft piece member are combined. It is characterized by projecting inward from the vertical plate portion.
[0023]
Therefore, in this case, in particular, since both side portions of the pressing convex portion of the shaft piece member are rotatably held by the holding piece protruding inward from the vertical plate portion of the coupling tool, the shaft piece member is coupled together. It can be easily held by holding it in advance, thereby preventing loss of the coaxial piece member and detachment from the coupling tool, and the shaft piece member can be smoothly rotated. As a result, the pressing convex portion is surely brought into sliding contact with the upper side surface of the channel material.
[0024]
A ceiling member support structure according to a fourth aspect of the present invention is the ceiling member support structure according to any one of the first to third aspects, wherein the channel member is penetrated through both the notch-shaped openings of the coupler, and both In a state where the convex rib portion of the T-bar material is locked to the locking piece, the pressing convex portion of the shaft piece member is moved outward from the vertical plate portion of the coupler located on the side opposite to the pressing sliding contact direction. The missing opening that escapes is formed continuously with the upper edge of the notch-shaped opening of the vertical plate portion.
[0025]
Therefore, particularly in this case, even when the shaft piece member is held between the two vertical plate portions of the coupler, the notch opening formed in one vertical plate portion and the lack formed continuously at the upper edge thereof. The pressing convex part of the coaxial piece member can be released to the outside from the opening. In this state, the coupling and fixing state of the channel material and the T bar material is released, and both of them are slid and moved through the same coupling tool. It is possible to adjust the position easily.
[0026]
The ceiling member support structure according to claim 5 of the present invention is the ceiling member support structure according to claim 4, wherein a claw-like piece is projected downward from the upper edge of the missing opening, and the claw-like piece is By plastically deforming inwardly, the pressing convex portion is pushed in the pressing sliding contact direction by the claw-like piece to rotate the shaft piece member.
[0027]
Therefore, in this case, in particular, the claw-like piece projecting downward from the upper edge of the above-mentioned missing opening is plastically deformed inward so that the pressing convex portion is in the direction of the sliding contact with the claw-like piece. The shaft piece member can be reliably rotated by being pushed, and this rotation operation is easily performed from the outside. In addition, the claw-like piece plastically deformed reliably prevents the shaft piece member from rotating in the return direction.
[0028]
A ceiling member support structure according to a sixth aspect of the present invention is the ceiling member support structure according to the fifth aspect, wherein the claw-like piece is formed in a substantially rectangular shape with a longitudinal cross-section projecting outward. The lower end portion of the claw-like piece is slidably contacted with the upper side surface of the channel material at the stage of plastically deforming inward.
[0029]
Therefore, in this case, in particular, the claw-shaped piece is formed in a substantially rectangular shape with a longitudinal section bent outwardly protruding, and at the stage of plastically deforming the claw-shaped piece inward, the lower end portion of the claw-shaped piece is Since it is slidably contacted with the upper surface of the channel material, the lower end portion of the claw-shaped piece surely presses the pressing convex portion of the shaft piece member. At this time, the tip of the lower end portion of the claw-like piece enters between the pressing convex portion and the upper surface of the channel material, and the channel material is pressed more firmly downward.
[0032]
  Claims of the invention7The ceiling member support structure described above is the above-mentioned claim.Any one of 1-6In the ceiling member support structure described above, the stopper piece projecting outwardly from the vertical plate portion at the upper edge portion of the notch-shaped opening of the vertical plate portion of the coupler located in the pressing sliding contact direction of the pressing convex portion. It is formed and the rotation of the shaft piece member is stopped by the pressing convex portion being stopped against the inner side surface of the stopping piece portion.
[0033]
Accordingly, in this case, in particular, a stopper piece that protrudes outward from the vertical plate portion is formed at the upper edge portion of the notch-shaped opening of the vertical plate portion of the coupler, and is formed on the inner surface of the stopper piece portion. Since the rotation of the shaft piece member at a stage slightly exceeding the neutral state is stopped by stopping the pressing convex portion, the coaxial piece member is reliably prevented from turning in the return direction.

In the ceiling member support structure of this embodiment, a substantially U-shaped vertical cross section is opened downward by a pair of vertical plate portions 1 facing each other with a gap therebetween and a horizontal plate portion 2 that connects the upper end edges of both vertical plate portions 1. A die-shaped coupler 3 is formed, and a locking piece 4 bent inward is formed at the lower end edge of both vertical plate portions 1 of the coupler 3 and is opened downward in the middle of the vertical plate portions 1. The cut-out openings 5 are formed, and the both cut-out openings 5 are placed on the channel material 6 so as to straddle the coupler 3 so that the channel material 6 laid across the ceiling base portion penetrates. ing.
[0035]
A T bar member 7 supporting a ceiling member with a substantially inverted T-shaped longitudinal section is disposed below the channel member 6 in a direction substantially perpendicular to the channel member 6, and along the upper edge of the T bar member 7. The formed convex rib portion 8 is locked so as to be held between the locking pieces 4 on both sides of the coupler 3. Further, between the horizontal plate portion 2 of the coupler 3 and the upper surface of the channel material 6, a shaft piece member 9 that rotates about an axis in a direction substantially orthogonal to the channel material 6 is held. A pressing protrusion 10 protruding downward is formed in the middle of the piece member 9.
[0036]
In this case, the shaft piece member 9 is made of a rod-like material, and the middle part of the coaxial piece member 9 is bent and projected downward to form the pressing convex portion 10. The shaft piece member 9 in the held state is rotated so that the pressing convex portion 10 is slidably contacted with the upper side surface of the channel material 6 and the channel material 6 is pressed downward. The lower side is brought into contact with the convex rib portion 8 of the T-bar member 7 to couple and fix them.
[0037]
Hereinafter, the ceiling member support structure of this embodiment will be described more specifically. The coupler 3 is formed by punching and bending a rectangular metal plate, and the distance between the two vertical plate portions 1 is 1.5 to 3 of the wire diameter of the rod-shaped material that becomes the shaft piece member 9 described later. It is formed in a substantially U-shape that is about 0 times as narrow. Both vertical plate portions 1 of the coupler 3 are formed with vertically elongated rectangular cutout openings 5 that are continuously opened in the same size and shape, and the cutout openings 5 are opened downward. A locking piece 4 bent in a substantially letter shape is formed at the lower end edge of both pieces divided on both sides. In addition, the opening width dimension of the notch-shaped opening 5 is formed to be substantially equal to the width dimension of the upper and lower flanges 16 of the channel material 6 which will be described later, and the channel material 6 penetrates so as to fit into both the notch-shaped openings 5. Is done.
[0038]
A plurality of channel members 6 are installed side by side on the ceiling base portion and are horizontally mounted. The channel member 6 is a metal C-type channel member having a vertically long cross section having a web 15 and upper and lower flanges 16. On the channel member 6, the coupler 3 is engaged and mounted so as to straddle the notch-like openings 5 so that the channel member 6 penetrates. A convex rib portion 8 of a T-bar member 7 having a substantially inverted T-shaped longitudinal section is engaged with the two pairs of engagement pieces 4 on both sides of the coupler 3 so as to be sandwiched from both sides. The T-bar material 7 is a metal mold, and is composed of a vertical piece portion 17 and a horizontal piece portion 18 projecting on both sides at the lower end thereof, and is a convex rib that is hollow along the upper end edge of the vertical piece portion 17 and has a substantially rectangular cross section. Part 8 is formed. Concave portions are formed on both sides of the lower surface of the convex rib portion 8, and the convex rib portion 8 is locked to the locking piece 4 so that the leading edge of the locking piece 4 enters the both concave portions. .
[0039]
A shaft piece member 9 is accommodated and held in the upper inner space of the coupler 3, and the shaft piece member 9 is rotated around an axis in a direction substantially orthogonal to the channel material 6. The shaft piece member 9 is formed by bending a metal rod-like material, and a pressing convex portion 10 that is bent downward and protruded in a substantially V shape is integrally formed at the middle portion thereof. . Both ends of the shaft piece member 9 protrude to both sides of the coupler 3, and both side portions of the pressing projection 10 of the coaxial piece member 9 abut on the lower surface of the horizontal plate portion 2 of the coupler 3, and this abutting portion The coaxial piece member 9 is rotated about the center axis.
[0040]
Further, the shaft piece member 9 is rotated so that the pressing convex portion 10 swings from the substantially vertical state to both sides. In this substantially vertical state, the coaxial piece member 9 is formed on the horizontal plate portion 2 of the coupler 3. The state of being stretched between the lower surface and the upper surface of the upper flange 16 of the channel member 6 is stopped and held. And if the shaft piece member 9 rotates to either side from the said rotation stop state in which the press convex part 10 will be in a substantially perpendicular state, the joint fixed state of the channel material 6 and the T-bar material 7 will be cancelled | released, The position can be adjusted by shifting each other. In that case, the pressing convex part 10 of the shaft piece member 9 protrudes from the upper part of one of the notch-shaped openings 5 of the coupler 3 to the outside of the vertical plate part 1, so that the coaxial piece member 9 has a large angle. It will be in the state reliably released by rotating.
[0041]
In order to construct the ceiling member support structure of this embodiment, the channel member 6 and the T-bar member 7 are mutually adjusted in position as described above, and then the shaft piece member is used with a tool P such as pliers as shown in FIG. 9, the coaxial piece member 9 is rotated so that the pressure convex part 10 is in a substantially vertical state, and the shaft piece member 9 is connected to the horizontal plate part 2 of the coupler 3. The rotation is stopped between the lower surface and the upper surface of the upper flange 16 of the channel member 6 in a stretched state. At that time, the tip portion of the tool P such as pliers enters the inner space of the coupler 3 from the upper part of the notch-shaped opening 5 on both sides of the coupler 3, and the shaft piece member 9 is easily rotated and stretched. Stop surely.
[0042]
Further, in the rotation stop state, the pressing convex portion 10 of the shaft piece member 9 is stopped and held in a state where it is slightly buried in the upper surface of the upper flange 16 of the channel material 6. The V-shaped elasticity also acts to reliably stop rotation without rattling, and the channel material 6 and the T-bar material 7 are securely and securely coupled to each other. That is, as described above, when the shaft piece member 9 is rotated, the pressing projection 10 is slidably contacted with the upper side surface of the channel material 6 and the channel material 6 is pressed downward. The lower side surface is brought into contact with the convex rib portion 8 of the T-bar member 7, so that both are firmly and securely bonded. And as shown in FIG. 2, the edge part of the ceiling board 19 is each mounted on the both sides of the horizontal piece part 18 of the T-bar material 7, and construction of the ceiling member support structure of this embodiment is completed.
[0043]
Therefore, in the ceiling member support structure of this embodiment, the convex rib portion 8 at the upper end edge of the T-bar member 7 is sandwiched between the opposing locking pieces 4 of the vertical plate portions 1 of the coupler 3. Since it is locked, the T-bar material 7 is supported in a stable state. In this state, by rotating the shaft piece member 9, the pressing convex portion 10 formed so as to protrude downward in the middle of the shaft piece member 9 is formed on the upper surface of the upper flange 16 of the channel member 6. The channel member 6 is slid and pressed downward, and the lower surface of the lower flange 16 of the channel member 6 is brought into contact with the convex rib portion 8 of the T-bar member 7 in a balanced manner. It is securely bonded and fixed in a stable state.
[0044]
In addition, since the shaft piece member 9 is held in a state where its rotation is regulated to some extent between the two vertically spaced vertical plate portions 1 of the coupler 3, the coaxial piece member is also affected by external forces such as vibration and earthquake during construction. 9 is difficult to rotate in the return direction from the stretched state, and the substantially vertical pressing state by the pressing convex portion 10 is easily maintained, and the coupled fixed state by this is also difficult to be released. Further, the structure of the coupling piece 3 and the shaft piece member 9 held substantially along the both vertical plate portions 1 of the coupling piece 3 is simplified as compared with the conventional example shown in FIGS. The connecting and fixing work can be easily performed by rotating the member 9.
[0045]
In the ceiling member support structure of this embodiment, the shaft piece member 9 is formed of a rod-shaped material as a pin, and the pressing protrusion 10 is simply formed by bending and projecting the middle of the shaft piece member 9 downward. It is also possible to manufacture the coaxial piece member 9 together with the pressing projection 10 as a single pin at a low cost. In the ceiling member support structure of this embodiment, the ceiling plate 19 is shown as the ceiling member supported by the T-bar member 7, but a ceiling member such as a lighting fixture may be supported.
[0046]
  FIG. 4 illustrates the present invention.PremiseCeiling member support structureAs a reference embodiment (hereinafter referred to as “second embodiment”)Is shown. In the ceiling member support structure of this embodiment, the horizontal plate portion 2 of the coupler 3 is formed so as to have a cross-sectional shape curved upward, and is brought into contact with the lower surface of the horizontal plate portion 2 of the shaft piece member 9. Therefore, the substantially vertical pressing state by the pressing protrusion 10 is more easily held, and the coupled and fixed state by this is reliably held. Further, when the shaft piece member 9 is rotated about the contact portion as a central axis, the central axis is difficult to move, and the coaxial piece member 9 can be smoothly rotated. In addition, it is comprised similarly to said 1st embodiment except that, and there exists an effect similar to said 1st embodiment.
[0047]
  5 and 6 show the present invention.PremiseCeiling member support structureAs a reference embodiment (hereinafter referred to as “third embodiment”).Is shown. In the ceiling member support structure of this embodiment, a claw-like piece 13 that hangs outward and downward is provided on the upper edge portion of the two notched openings 5 of the coupler 3, and the claw-like pieces 13 are projected from both sides with pliers. The shaft piece member 9 can be rotated by being sandwiched by a tool such as the like, and the coaxial piece member 9 can be easily brought into a substantially vertical pressing state in which the pressing protrusion 10 is stretched. In this case, the claw-shaped piece 13 is plastically deformed, and the pressing projection 10 is pushed from both sides by the claw-shaped piece 13 so that the shaft piece member 9 is reliably rotated. It can be done easily. Moreover, the plastically deformed claw-like piece 13 reliably prevents the shaft piece member 9 from rotating in the return direction. In addition, it is comprised similarly to said 2nd embodiment except that, and there exists an effect similar to said 2nd embodiment.
[0048]
  7 and 8 show claims 1, 2, 4 to 5 of the present invention.6The ceiling member support structure which is 4th embodiment corresponding to is shown. In the ceiling member support structure of this embodiment, the channel material 6 is passed through the notch-shaped openings 5 of the coupler 3 and the protruding rib portions 8 of the T-bar material 7 are locked to the locking pieces 4. The missing opening 12 for allowing the pressing convex portion 10 of the shaft piece member 9 to escape to the outside of the vertical plate portion 1 of the coupler 3 located on the side opposite to the pressing sliding contact direction α (right side in the drawing) is the same. It is formed by continuously opening the upper edge portion of the notch-shaped opening 5 of the vertical plate portion 1.
[0049]
Therefore, in this case, even when the shaft piece member 9 is accommodated and held between the two vertical plate portions 1 of the coupler 3, as shown in FIG. 7, the notch-shaped opening 5 formed in one vertical plate portion 1 and its The pressing convex portion 10 of the coaxial piece member 9 can be released outwardly from the lack opening 12 formed continuously at the upper edge, and in this state, the coupling and fixing state of the channel material 6 and the T-bar material 7 is released. Therefore, both of them can be slid and moved in the orthogonal direction through the same coupler 3 and can be easily adjusted in position.
[0050]
Further, in the ceiling member support structure of this embodiment, the claw-like piece 13 is projected downward from the upper edge of the missing opening 12, and the claw-like piece 13 is plastically deformed inward with a tool such as pliers. Thus, the claw-like piece 13 pushes the pressing projection 10 in the pressing / sliding direction α to rotate the shaft piece member 9. Therefore, in this case, the claw-like piece 13 is plastically deformed inward, so that the claw-like piece 13 pushes the pressing convex portion 10 in the pressing-sliding contact direction α, thereby reliably rotating the shaft piece member 9. This rotation operation is easily performed from the outside. In addition, as shown in FIG. 8, the plastically deformed claw-like piece 13 reliably prevents the shaft piece member 9 from rotating in the return direction.
[0051]
Further, in the ceiling member support structure of this embodiment, the claw-like piece 13 is formed in a substantially rectangular shape with a longitudinal section bent outwardly protruding, and the claw-like piece 13 is plastically deformed inward. The lower end portion of the strip 13 is in sliding contact with the upper side surface of the upper flange 16 of the channel member 6. Therefore, in this case, since the lower end portion of the claw-like piece 13 is slidably contacted with the upper surface of the channel material 6 at the stage of plastic deformation of the claw-like piece 13 inward, the lower end portion of the claw-like piece 13 is The pressing convex portion 10 of the shaft piece member 9 is surely pressed. At that time, the tip of the lower end portion of the claw-like piece 13 enters between the pressing convex portion 10 and the upper side surface of the channel material 6 so that the channel material 6 is pressed more firmly downward. .
[0052]
Further, in the ceiling member support structure of this embodiment, when the pressing convex portion 10 of the shaft piece member 9 slightly exceeds the neutral state in the pressing sliding contact direction α, the pressing convex portion 10 is one of the couplers 3. The contact with the inner surface of the vertical plate portion 1 is stopped, and the rotation of the coaxial piece member 9 is stopped. Therefore, in this case, the pressing convex portion 10 of the shaft piece member 9 is slightly in a neutral state in the pressing sliding contact direction α (the pressing convex portion 10 is most pressed against the upper surface of the channel material 6 and pressed). At the stage of exceeding, the rotation of the coaxial piece member 9 is stopped, and in this stopped state, the coaxial piece member 9 is held in a stable state without rotating in the return direction.
[0053]
Moreover, since the elasticity of the pressing convex portion 10 bent into a substantially V shape of the shaft piece member 9 acts at that time, the pressing convex portion 10 is most strongly pressed against the upper surface of the channel material 6 and pressed. Even if it is slightly deviated from the existing state, a stable holding state in which the rotation of the coaxial piece member 9 is stopped is ensured. Furthermore, since the rotation of the shaft piece member 9 is stopped slightly beyond the neutral state, a click feeling is generated at that time, so that the operator can visually confirm that the connection is fixed by this click feeling. Can do.
[0054]
In addition, it is comprised similarly to said 3rd embodiment except that, and there exists an effect similar to said 3rd embodiment. Further, in the first to third embodiments, the missing opening 12 is not described, but the missing opening 12 is formed by forming the notched opening 5 large upward. In the first to third embodiments, the same operational effects as in the fourth embodiment are exhibited.

The plate portion 2 has a flat plate shape, and a pair of holding holes 21 are formed on both sides of the horizontal plate portion 2. The shaft piece member 9 is held in a state in which it is difficult to be detached from the coupler 3 by the both standing piece portions 20 being inserted into the holding holes 21 from below and held in engagement.
[0056]
Further, in this case, even if the horizontal plate portion 2 of the coupler 3 is flat, both the standing piece portions 20 are engaged and held in the holding holes 21, so that the shaft piece member 9 is rotated at its central axis. The shaft piece member 9 can be smoothly rotated, and the coaxial piece member 9 is held in a stable state even when the shaft piece member 9 is rotated. Is easily held, and thereby, the coupled and fixed state is ensured. Other than that, the configuration is the same as in the fourth embodiment, and the same effects as in the fourth embodiment are achieved.

It is.
[0058]
Therefore, in this case, the stop piece portion that is bent and protrudes outward from the vertical plate portion 1 at the upper edge portion of the notch-shaped opening 5 of the vertical plate portion 1 located on the opposite side to the claw-like piece 13 of the coupler 3. 14 is formed, and by pressing the pressing convex portion 10 rotating in the pressing and sliding contact direction α on the inner side surface of the stopping piece portion 14, as described in the fourth embodiment, Since the rotation of the shaft piece member 9 at a stage slightly exceeding the neutral state is stopped, the rotation of the coaxial piece member 9 in the return direction is reliably prevented and held in a more stable state.
[0059]
Moreover, in the ceiling member support structure of this embodiment, both the holding holes 21 through which both the standing piece portions 20 of the shaft piece member 9 are inserted and engaged extend from the horizontal plate portion 2 of the coupler 3 to one vertical plate portion 1. It has a long hole shape. Therefore, in this case, the degree of freedom increases in the engaged and held state between the standing piece 20 and the holding hole 21, and the shaft piece member 9 can be rotated more smoothly. Other than that, the configuration is the same as in the fifth embodiment, and the same effects as in the fifth embodiment are achieved.
[0060]

Projects inward.
[0061]
Accordingly, in this case, both side portions of the pressing convex portion 10 of the shaft piece member 9 are rotatably held by both holding pieces 11 projecting inward from the vertical plate portion 1 of the coupler 3. The member 9 is preliminarily held and assembled in the coupler 3 at a factory or the like, and handling thereof can be facilitated. As a result, the management of the member becomes easy, and the shaft piece member 9 can be prevented from being lost or detached from the coupler 3, and the shaft piece member 9 is stably held and can be smoothly rotated. The pressing protrusion 10 comes into sliding contact with the upper surface of the channel member 6 with certainty.

Therefore, as shown in FIG. 17, when the partition 23 is attached and fixed to the lower side of the horizontal piece 18 of the T-bar member 7 with screws 24, the attachment pieces 22 on both sides are connected to the channel member with screws 24. By attaching and fixing to the web 15 of 6, a strong casing structure can be obtained. In this case, the attachment piece 22 may be welded to the web 15 of the channel material 6, and the shaft piece member 9 in the present invention functions as a temporary fixing means instead of the main fixing. Other than that, the configuration is the same as in the sixth embodiment, and the same effects as in the sixth embodiment are achieved.
