Description

【０００１】
【発明の属する技術分野】
本発明は、天井パネルの接続構造に関するものである。
【０００２】
【従来の技術】
従来からユニットルームの天井部は壁パネルに接続される天井パネルで構成されており、隣接する天井パネルの接続には以下に示すような天井パネルの接続構造が知られていた。図５に示すように隣接する天井パネル１′、２′の一辺に沿った側端面を天井パネル接続部とし、両天井パネル１′、２′は天井パネル接続部を面合わせにすることで接続されている。両天井パネル１′、２′は同じ厚みを有しており、両天井パネル１′、２′の上面の一辺側の側端部にはそれぞれ上向きに突出する接続片１４ａ、１４ｂが設けられており、接続片１４ａにはねじ具１６よりもやや大きめの径を有するねじ具用孔１５ａが穿孔している。接続片１４ｂにもねじ具用孔１５ｂが穿孔しており、両ねじ具用孔１５ａ、１５ｂは対向した位置に形成されている。各天井パネル１′２′の外端部にはユニットルームの壁パネルの上端部と接続するための連結手段が設けられおり、一方の天井パネル１′には点検口が設けられている。
【０００３】
上記隣接する天井パネル１′、２′をユニットルームに固着する際は、両天井パネル１′、２′の外端部を壁パネルの上端部に載置して、連結手段により壁パネルと各天井パネル１′、２′を接続すると共に、図５に示すように隣接する両天井パネルの１′、２′の天井パネル接続部を面合わせにし、接続片１４ａ、１４ｂに設けた両ねじ具用孔１５ａ、１５ｂにねじ具１６を挿入してナット１７にてねじ止めし、両天井パネル１′、２′を接続する。
【０００４】
しかしながら上記従来の天井パネルの接続構造では、ねじ具用孔１５ａ、１５ｂはねじ具１６の径よりもやや大きめに形成してあるため、両天井パネル１′、２′を上下方向にずらした状態でねじ具によって接続してしまい、意匠面側にあたる両天井パネル１′、２′の下面に面段差が発生してしまうという問題があった。またねじ具１６による接続は作業者が点検口より一方の天井パネル１′の上方に入って行うので、両天井パネル１′、２′の下面を見ることができず、両天井パネル１′、２′の下面を面段差のない状態で接続することは非常に難しかった。さらに両天井パネル１′、２′はねじ具１６のみで接続されているため、一方の天井パネル１′上面に重量物２１等が載せられるとねじ具用孔１５ａ、１５ｂの周囲に応力集中がおこり、接続辺１４ａ、１４ｂが変形してしまったり、ねじ具１６が脱落してしまったりして、接続強度に問題があった。
【０００５】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは両天井パネルを容易且つ綺麗に接続でき、加えて接続が強固な天井パネルの接続構造を提供することを課題とするものである。
【０００６】
【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に係る天井パネルの接続構造は、一方の天井パネル１の一辺に沿った側端面と他方の天井パネル２の一辺に沿った側端面とを接続面とし、両天井パネル１、２の接続面を面合わせにしてねじ具にて接続する天井パネルの接続構造であって、一方の天井パネル１の接続面の上部に他方の天井パネル２に向かって突出する載置片３を設け、他方の天井パネル２の接続面の上端部に載置用段部６を設け、他方の天井パネル２の載置用段部６よりも上部の位置に一方の天井パネル１に向かって突出する浮き上がり防止片５を設け、一方の天井パネル１に設けた載置片３を載置用段部６に載置し、他方の天井パネル２に設けた浮き上がり防止片５の下面にて一方の天井パネル１の上面の一辺側の側端部を押さえ、両天井パネル１、２の接続面をねじ具にて接続するものとし、一方の天井パネル１の一辺の両端部において最端部よりやや引き込んだ位置から載置片３を設け、他方の天井パネル２の一辺の両端部にそれぞれ上向きに突出する当たり片１０を設け、両当たり片１０の内側面を当接面９とし、両当接面９の下端部から内側方に向けて載置用段部６を形成し、載置片３の一辺に沿った方向における両側端面と当接面９とが当接して成ることを特徴とするものである。
【０００７】
上記のように載置片３を載置片段部６に載置し、浮き上がり防止片５にて一方の天井パネル１の上面を押さえることで、一方の天井パネル１を他方の天井パネル２に載置するだけで両天井パネル１、２の位置合わせができ、両天井パネル１、２を上下にがたつかない状態でねじ具により接続することができる。さらに両天井パネル１、２を接続した際には載置用段部６に載置片３が載置されているので、一方の天井パネル１の荷重は載置用段部６とねじ具とにかかることとなり、応力集中を緩和することができる。また載置片３の一辺に沿った方向における両端面と当接面９とが当接するように形成することで、一方の天井パネル１を他方の天井パネル２に載置するだけで上下方向に加えて一辺に沿った方向においても位置合わせでき、また上下方向に加えて一辺に沿った方向にもがたつくことなく両天井パネル１、２をねじ具にて接続することができる。
【０００８】
また請求項２記載の天井パネルの接続構造は請求項１記載の天井パネルの接続構造において、他方の天井パネル２の接続面側の一辺に沿った方向において載置用段部６を設けていない部分に幅狭の浮き上がり防止片５を設けて成ることを特徴とするものである。
【０００９】
上記のように載置用段部６を設けていない部分に幅狭の浮き上がり防止片５を設けることで、浮き上がり防止片５が邪魔することなく載置片３を載置用段部６に載置することができる。
【００１２】
請求項３記載の天井パネルの接続構造は、請求項１又は請求項２記載の天井パネルの接続構造において、両天井パネル１、２の接続面側の一辺を除く周縁部に垂下する起立板１１ａ、１１ｂを設け、両天井パネル１、２の起立板１１ａ、１１ｂの下端部に外向きに突出するフランジ部１９ａ、１９ｂを周設し、両天井パネル１、２の起立板１１ａ、１１ｂとフランジ部１９ａ、１９ｂとの接続面側の側端面を接合面とし、接続面と接合面とで天井パネル接続部とし、両天井パネル１、２の天井パネル接続部を面合わせにして接続する天井パネルの接続構造であって、他方の天井パネル２のフランジ部１９ｂの接合面に一方の天井パネル１側に突出する突起７を設け、一方の天井パネル１のフランジ部１９ａの接合面に突起７と嵌合する突起嵌合部８とを設けて成ることを特徴とするものである。
【００１３】
上記のように天井パネルの変形によりずれやすい位置にある両フランジ部１９ａ、１９ｂのそれぞれの接合面に突起７と突起嵌合部８とを設けることで、一方の天井パネル１のフランジ部１９ａの接合面と他方の天井パネル２のフランジ部１９ｂの接合面とがずれることなく一方の天井パネル１を他方の天井パネル２に載置することができるとともに一方の天井パネル１を他方の天井パネル２にねじ具にて固着することができる。
【００１４】
【発明の実施の形態】
以下、本発明を添付図面に示す実施形態に基づいて説明する。本実施形態における天井パネルの接続構造は一方の天井パネル１の一辺に沿った側端面と他方の天井パネル２の一辺に沿った側端面とを接続面とし、両天井パネル１、２の接続面を面合わせにして両天井パネル１、２をねじ具にて接続するものである。
【００１５】
なお本発明の天井パネルの接続構造はユニットルームの天井部分に使用される場合が想定され、以下にはこの実施形態を示すが、本発明はこれに限定されるものでなく、また以下の説明に使用する方向は天井パネル接続時における一辺に沿った方向を前後方向とし、接続面に直交する方向を左右方向としている。
【００１６】
図１に示すように一方の天井パネル１の平面視長方形状の天板２６の平面視中央部には方形状の点検口２５が設けられており、天板２６の一辺を除く周縁部にはほぼ下方に垂下する起立板１１ａを周設している。この起立板１１ａの下端部には全周に亘って外側方に突出するフランジ部１９ａが周設されており、フランジ部１９ａにはユニットルームに固着するための連結手段（図示せず）が設けられている。起立版１１ａ及びフランジ部１９ａの接続面側の側端面を接合面とし、上記接続面と接合面とで天井パネル接続部を構成している。
【００１７】
天板２６の接続面の上端部には前後方向において両最端部よりやや引き込んだ位置からほぼ全長に亘って他方の天井パネル２側に突出する幅広の載置片３が天板２６と一体に設けられている。つまり一方の天井パネル１の一辺の両端部は図４に示すように一方の天井パネル１の天板２６の一辺側の側端面の上部の前後方向における両端部を除いた部分に載置片３を設けており、載置片３を設けていない一方の天井パネル１の一辺の両端部には端段部２０を形成している。載置片３の上面及び天板２６の右側端部上面には上向きに突出する載置片基部３０が載置片３と一体に設けられており、載置片基部３０の右側端面の前後方向における中央には左方に伸びる溝部３１が設けられており、この溝部３１によって露出した天板２６の上面を浮き上がり防止片用受部２４とし、また溝部３１の溝は載置片基部３０の中央付近まで溝が伸びている。載置片基部３０の左側端面の前後方向における両端部と溝部３１との間の部分には右方に伸びる固着具用溝部３２が複数（図面では前側２個、後側２個）設けられており、固着具用溝部３２の右方に形成された面には図２に示すようにねじ具挿入孔２２が穿孔している。さらに一方の天井パネル１の後部側のフランジ部１９ａの接合面の前後方向におけるほぼ中央部の下端部には突起嵌合部８を設けている。該突起嵌合部８は下方と他方の天井パネル側とに開口しており、後述する突起７と嵌合するように形成されている。
【００１８】
他方の天井パネル２の平面視長方形状の上板３５の一辺を除く周縁部にはほぼ下向きに垂下する起立板１１ｂが全周に亘って周設されており、上板３５の左側端部にはほぼ下向きに突出する側板３６が設けられている。該側板３６は下端が天井パネル接続時に一方の天井パネル１の天板２６の右側端面の下端と同じ高さになるように形成されている。側板３６の左側面の下端部と起立板１１ｂの左側端面とには外側方に向かって突出する縁部３７が設けられている。縁部３７、起立板１１ｂの下端部には外向きに突出するフランジ部１９ｂが周設されており、ユニットルームの壁パネルの上端部に固着するための連結手段（図示せず）が設けられている。この他方の天井パネル２の縁部３７の左側面を接続面とし、また起立板１１ｂ及びフランジ部１９ｂの接続面側の側端面を接合面とし、接続面と接合面とで天井パネル接続部を構成している。
【００１９】
縁部３７の前後方向における両端部にはそれぞれ上向きに突出する当たり片１０を縁部３７と一体に設けており、また縁部３７の前後方向における中央部には上端が一方の天井パネル１の浮き上がり防止片受部２４と同じ高さまで伸びる上向き凸片２５を縁部３７と一体に設けており、これによって縁部３７の当たり片１０と上向き凸片２５を設けていない部分には上方と左方とに開口する載置用段部６が形成される。両当たり片１０の載置用段部６側の側面（内側面）は当接面９とし、両当接面９は載置片３の端段部２０に面した両側端面とが当接するように形成されている。また上向き凸片２５の上面の前後方向における一部（他方の天井パネル２の一辺に沿った方向における中央部）には図１に示すように上向きに突出する浮き上がり防止片基部３８を設けている。該浮き上がり防止片基部３８は縁部３７の前後方向において中央に位置しており、また浮き上がり防止片基部３８は前後方向において幅狭である。この浮き上がり防止片基部３８の左側面には一方の天井パネル１に向かって突出する浮き上がり防止片５を浮き上がり防止片基部３８と一体に設けており、浮き上がり防止片５は浮き上がり防止片基部３８と同様に幅狭である。該浮き上がり防止片５は下面が天井パネル接続時に溝部３１の下端に形成された浮き上がり防止片受部２４に載置できるように形成されている。載置用段部６の右側端部には上向きに突出する板３９が設けてあり、該板３９の左側面の一方の天井パネル１のねじ具挿入孔２２に対応する部分にはねじ具挿入口２２より挿入したねじ具をねじ止めできるようにめねじ具２３を設けている。また図３に示すように他方の天井パネル２の後部のフランジ部１９ｂの接合面の前後方向における中央部には一方の天井パネル１側に突出する突起７を設けており、該突起７は前述の突起嵌合部８に嵌合するように形成されている。
【００２０】
上記一方の天井パネル１の起立板１１ａは天板２６より下方に行くにつれて外側方に向かって傾斜して設けられており、また他方の天井パネル２の起立板１１ｂと側板３６も下方に行くにつれて外側方に向かって傾斜して設けられている。これによって両天井パネル１、２をユニットルームの壁パネルに接続した際に意匠面である両天井パネル１、２の下面が傾斜によって美しく見えるようになり、商品価値を高めている。また他方の天井パネル２の上板３５は下面に照明器具や換気口等を設けるために一方の天井パネル１の天板２６よりも高い位置に配設されている。
【００２１】
上記両天井パネル１，２をユニットルームの壁パネルに固着する場合は、他方の天井パネル２のフランジ部１９ｂの下面を壁パネルに載せ、フランジ部１９ｂに設けられた連結手段により壁パネルと他方の天井パネル２とを固着する。
【００２２】
次に壁パネルに固着された他方の天井パネル２に一方の天井パネル１を連結すると共に、一方の天井パネル１を壁パネル上端部に連結する。
【００２３】
両天井パネル１、２の連結する場合は、一方の天井パネル１の載置片３を他方の天井パネル２の載置用段部６に載置し、一方の天井パネル１を他方の天井パネル２に載置させる。一方の天井パネル１を他方の天井パネル２に載置することで、意匠面である両天井パネル１、２の下面を面段差のない状態に支持しており、また一方の天井パネル１に設けたねじ具挿入口２２と他方の天井パネル２のめねじ具２３の位置が一致した状態で支持している。この場合図４に示すように一方の天井パネル１の浮き上がり防止片受部２４には幅狭の浮き上がり防止片５の下面が位置しており、一方の天井パネル１の上下方向のがたつきを防止している。また幅狭の浮き上がり防止片５は接続面に前後方向において部分的に設けているので、載置片３を載置用段部６に載置するにあたって邪魔にならない。またこれと同時に一方の天井パネル１の載置片３の前後方向における両端面と他方の天井パネル２の当接面９とが当接し、両フランジ部１９ａ、１９ｂの接合面に設けた突起７と突起嵌合部８とが嵌合する。載置片３の両端面と当接面９とが当接することで、一方の天井パネルの前後方向におけるがたつきを防止し、加えて突起７と突起嵌合部８とが嵌合することで、天井パネルの変形によりずれやすい位置にある両フランジ部１９ａ、１９ｂのそれぞれの接合面のがたつきを防止することができる。また突起嵌合部８の下方は開口しているために一方の天井パネル１を突起嵌合部８を他方の天井パネル２の突起７に上方から容易に被嵌することができる。
【００２４】
またねじ具による取付けは上記のように一方の天井パネル１を他方の天井パネル２に前後左右に動かない状態に位置決めして連結した両天井パネル１、２を点検口２５より手を入れてねじ具にて接続する。上述したように両天井パネル１、２は前後左右に動かない状態に位置決めされて支持されているので、ねじ具挿入口２２とめねじ具２３の位置が一致した状態にあり、がたつきのない状態でねじ具による取付けを行うことができ、さらに意匠面である両天井パネル１、２の下面がずれていない状態でねじ止めを行うことができる。
【００２５】
さらに一方の天井パネル１をユニットルームの壁パネルと連結する場合は、一方の天井パネル１に設けられた連結手段によって一方の天井パネル１と壁パネルの上端部とを連結する。
【００２６】
また本実施形態における天井パネルの接続構造は一方の天井パネル１の突出片３を他方の天井パネル２の載置用段部６に載置し、ねじ具によって両天井パネル１、２の接続を行うので、一方の天井パネル１の荷重は載置用段部６とねじ具とにかかることとなり、ねじ具挿入孔２２及びめねじ具２３付近の応力集中を緩和することができる。
【００２７】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、一方の天井パネルを他方の天井パネルに載置するだけで両天井パネルの位置合わせができ、両天井パネルをがたつかない状態に保持することができるため、簡単に両天井パネルをねじ具により取付けることができ、且つ両天井パネルの下面を面一にできるようになり、意匠面である両天井パネルの下面を綺麗に接続することができる。また両天井パネルを接続した際には載置用段部に載置片が載置されるので、一方の天井パネルの荷重はねじ具と載置用段部とにかかることとなり、応力集中を緩和することができ、天井パネルの接続強度を増すことができる。また載置片の一辺に沿った方向における両端面と当接面とが当接するように形成することで、一辺に沿った方向においても両天井パネルの位置を合わせると共にがたつきを防止することができ、より容易に両天井パネルのねじ具による取付けを行うことができ、また両天井パネルが一辺に沿った方向にずれることがなくなり、意匠面である両天井パネルの下面を綺麗に接続することができる。
【００２８】
また請求項２記載の発明にあっては上記請求項１記載の発明の効果に加えて、載置用段部を設けていない部分に幅狭の浮き上がり防止片を設けることで、浮き上がり防止片が邪魔することなく載置片を載置用段部に載置することができるようになり、簡単に一方の天井パネルを他方の天井パネルに載置することができる。
【００３０】
また請求項３記載の発明にあっては、上記請求項１又は請求項２記載の発明の効果に加えて、他方の天井パネルのフランジ部の接合面に突起を設け、一方の天井パネルのフランジ部の接合面に突起と嵌合する突起嵌合部を設けることで、天井パネルの変形によりずれやすい位置にある一方の天井パネルのフランジ部の接合面及び他方の天井パネルのフランジ部の接合面との位置を合わせるとともにがたつきを防止することができ、より一層容易且つ綺麗に両天井パネルをねじ具にて固着することができる。
