【発明が解決しようとする課題】
天井パネル同士の接続は、立設した側壁パネル上での現場作業なので、対峙する一対の折り返し部に形成されたボルト挿通孔を正対させるのは容易ではなく、天井パネルの接続作業は困難であった。
本発明は上記問題に鑑みてなされたものであり、樹脂成形分割天井パネルの接続部に一般に配設される補強部材を利用して、前記ボルト挿通孔を容易に正対させることができ、ひいては現場作業が容易なユニットルームの分割天井接続構造を提供することを目的とする。
【０００５】
【課題を解決するための手段】
上記課題を解決するために、本発明においては、上方へ折り返された樹脂成形第１天井パネルの第１側縁部と、上方へ折り返されて第１天井パネルの第１側縁部に対峙する樹脂成形第２天井パネルの第２側縁部と、第１側縁部に固定され第１側縁部に沿って延在する第１補強部材と、第２側縁部に固定され第２側縁部に沿って延在する第２補強部材とを備え、第１補強部材の一部が第２側縁部へ向けて延び第２側縁部の上縁に当接し、第２補強部材の一部が第１補強部材の前記一部に平行に延び下方から対峙し、更に第１補強部材の前記一部と第２補強部材の前記一部とに係合するボルトを備えることを特徴とするユニットルームの分割天井接続構造を提供する。
【０００６】
本発明に係るユニットルームの分割天井接続構造においては、第１側縁部に固定され第１側縁部に沿って延在する第１補強部材の一部を第２側縁部へ向けて延在させ、第２側縁部に固定され第２側縁部に沿って延在する第２補強部材の一部を第１補強部材の前記一部に平行に延在させ下方から対峙させたので、第２天井パネルの第２側縁部の上縁が第１補強部材の前記一部に当接した時に、第２天井パネルの第２側縁部に形成したボルト挿通孔と、第１天井パネルの第１側縁部に形成したボルト挿通孔とが正対するように、第２側縁部のボルト挿通孔と第１側縁部のボルト挿通孔とを位置決めしておけば、現場での天井パネル接続作業時には、作業者が第１補強部材の前記一部と第２補強部材の前記一部とに手を掛け、第２補強部材の前記一部を第１補強部材の前記一部へ引き寄せ、第２側縁部の上縁を第１補強部材の前記一部に当接させるだけで、第２側縁部のボルト挿通孔を第１側縁部のボルト挿通孔に正対させることができる。従って、本発明に係るユニットルームの分割天井接続構造は、現場作業が容易である。本発明においては、樹脂成形分割天井パネルの接続部に一般に配設される補強部材の形状を工夫した簡便な機構により、現場での分割天井の接続作業を容易化している。
本発明に係るユニットルームの分割天井接続構造においては、ユニットルームの分割天井接続構造は、第１補強部材の前記一部と第２補強部材の前記一部とに係合するボルトを備えるので、ボルトを締め付けることにより、第２補強部材の前記一部を第１補強部材の前記一部へ容易に引き寄せることができる。
【０００７】
本発明の好ましい態様においては、前記ボルトは、第１補強部材の前記一部と第２補強部材の前記一部とに係合した後、取り外されて第１天井パネルの第１側縁部と第２天井パネルの第２側縁部との接続に使用される。
第２補強部材の前記一部を第１補強部材の前記一部へ引き寄せて、第２側縁部に形成したボルト挿通孔を第１側縁部に形成したボルト挿通孔に正対させた後、前記ボルトを取り外して、第１側縁部と第２側縁部との接続に使用すれば、分割天井接続構造の部品数増加を防止できる。
【０００８】
本発明の好ましい態様においては、第１補強部材と第２補強部材とはアングル材である。
アングル材の一方の脚部を天井パネルの上方へ折り返された側縁部へ固定すれば、他方の脚部を前記補強部材の前記一部として利用することができる。アングル材の利用により、補強部材の前記一部を容易に形成することができる。

【００１０】
図１、２に示すように、第１側縁部１ａと第１補強部材３の前記一方の脚部とを貫通するボルト挿通孔５が、第１側縁部１ａの延在方向に互いに間隔を隔てて複数配設されている。第２側縁部２ａと第２補強部材４の前記一方の脚部とを貫通するボルト挿通孔６が、第２側縁部２ａの延在方向に互いに間隔を隔てて複数配設されている。ボルト挿通孔５とボルト挿通孔６とは、第２側縁部２ａの上縁が第１補強部材の脚部３ａの下面に当接した時に、互いに正対するように位置決めされている。また、ボルト挿通孔５とボルト挿通孔６とが正対した時に、第２側縁部２ａ直下の第２パネル２の下面が第１側縁部１ａ直下の第１パネル１の下面と面一になるように、第２側縁部２ａの高さが設定されている。
【００１１】
ユニットルームの組立現場で、立設されたユニットルーム側壁に天井パネルを取り付ける際には、図１に示すように、第１天井パネル１と第２天井パネル２とをユニットルーム側壁上に順次載置し、次いで図２に示すように、作業者が第１補強部材の脚部３ａと第２補強部材４の脚部４ａとに手を掛け、第２補強部材の脚部４ａを第１補強部材の脚部３ａへ引き寄せ、第２側縁部２ａの上縁を第１補強部材の脚部３ａの下面に当接させる。ボルト挿通孔５とボルト挿通孔６とが正対し、且つ第２側縁部２ａ直下の第２パネル２下面が、第１側縁部１ａ直下の第１パネル１下面と面一になる。作業者は、ボルト挿通孔５、６にボルト７螺合させて、第１側縁部１ａと第２側縁部２ａとを接続する。第１天井パネル１と第２天井パネル２とが段差を生ずることなく接続される。
【００１２】
本実施例に係るユニットルームの分割天井接続構造によれば、作業者が第１補強部材の脚部３ａと第２補強部材の脚部４ａとに手を掛け、第２補強部材の脚部４ａを第１補強部材の脚部３ａへ引き寄せるだけで、第２側縁部２ａと第２補強部材４とに形成したボルト挿通孔６を第１側縁部１ａと第１補強部材３とに形成したボルト挿通孔５に正対させることができる。従って、本実施例に係るユニットルームの分割天井接続構造は、現場作業が容易である。本実施例に係るユニットルームの分割天井接続構造においては、樹脂成形分割天井パネルの接続部に一般に配設される補強部材の形状を単なる帯板ではなくアングルとする工夫により、簡便な機構で、現場での分割天井の接続作業を容易化している。
第１天井パネル１と第２天井パネル２とが段差を生ずることなく接続されるので、ユニットルームの快適性が向上する。
【００１３】
図３に示すように、第１補強部材の脚部３ａと第２補強部材４の脚部４ａとに螺合させたボルト７を締め付けて第２補強部材４の脚部４ａを第１補強部材の脚部３ａへ引き寄せても良い。第２補強部材４の脚部４ａを容易に第１補強部材の脚部３ａへ引き寄せることができる。第２側縁部２ａの上縁が第１補強部材の脚部３ａの下面に当接した後、ボルト７を順次取り外して天井パネルの接続に順次使用すれば、部品数の増加を招くことなく天井パネルの接続作業を効率化できる。
【００１４】
第１補強部材３、第２補強部材４を単なる帯板とし、第２天井パネル２側へ延びる脚部と、当該脚部に平行に延び下方から対峙する脚部とを、離散的に第１補強部材３、第２補強部材４に形成し或いは固定しても良い。これにより、分割天井接続構造が軽量化される。これに対し、第１補強部材３、第２補強部材４をアングル材で形成すると、第２天井パネル２側へ延びる脚部と、当該脚部に平行に延び下方から対峙する脚部とを容易に形成できるという利点がある。
【００１５】
