【発明の属する技術分野】
本発明は、給水管,給湯管,ガス管,排水管等の配管,電気配線等の配線等を含む配管類設置構造および配管類設置方法ならびに建物ユニットの組立て方法に関する。
【0002】
【従来の技術】
従来、ユニット建物のための配管設置構造として、たとえば特許第2579706号公報において、建物ユニットの上面または下面に沿って設備配管ユニットを配置し、この設備配管ユニットに配管類を収容した構造のものがある。
【0003】
【発明が解決しようとする課題】
しかしながら、上記従来の配管設置構造には以下の問題点がある。
(1)設備配管ユニットは建物ユニットの構造体とは別体であり、たとえば下階建物ユニットの天井構造体と上階建物ユニットの床構造体の間に設置される。
従って、設備配管ユニットは、建物の構造強度的には余剰部分であり、かつ、建物の天井高をそのユニット厚み分だけ減縮する等、建物の構造上の合理性を損なうことになる。
【0004】
(2)設備配管ユニットは、建物ユニットの上面または下面に沿う大サイズ,大重量をなし、建築現場でクレーン等により単独で吊り上げられて設置されるものであり、据付性も悪い。
【0005】
(3)設備配管ユニットは、前述のとおり、たとえば下階建物ユニットの天井構造体と上階建物ユニットの床構造体の間に挟まれて設置されるものであり、ユニット建物ではない一般建物への導入に困難がある。
【0006】
本発明の目的は、ユニット建物などの建物において配管類を簡易、かつ、合理的に設置することにある。
【0007】
【課題を解決するための手段】
請求項1に記載の本発明は、建物の床、天井または壁を構成する構造体の面材取着領域のうちの一部に定められた配管パネルセット用スペースを除いた面材取着領域に、面材を取付けて、前記配管パネルセット用スペースに配管パネルをセットする際、この配管パネルに予め配管類を設置して、該配管パネルを構成する床面材に設けられた孔から、各種設備と接続可能となるように、該配管類が立ち上げられている配管類設置構造である。
【0008】
請求項2に記載の本発明は、建物ユニットの床、天井または壁を構成する構造体の面材取着領域のうちの一部に定められた配管パネルセット用スペースを除いた面材取着領域に、面材を取付けて、前記配管パネルセット用スペースに配管パネルをセットする際、この配管パネルに予め配管類を設置して、該配管パネルを構成する床面材に設けられた孔から、各種設備と接続可能となるように、該配管類が立ち上げられていることを特徴とする配管類設置構造。

【0022】
建物ユニット10は、工場生産段階で、図1に示すように、床構造体11(床フレーム)の4コーナー部に角鋼管などからなる柱12を接合し、柱12の上部に天井構造体13を接合して構築される。
【0023】
床構造体11は、図1に示すように、2本の溝形鋼製桁床梁21と2本の溝形鋼製妻床梁22からなる床枠組内で、相対する桁床梁21、21の長手方向複数位置に角鋼管製床小梁23を接合し、床小梁23の上に床根太24を取着し、床根太24の上に床面材25を取着することにて構成される。

そして、建物ユニット10にあっては、工場生産段階で、図1に示すように、床構造体11の内部の床面材25の裏側に、洗面台40、バスユニット50のための配管類60を設置するとともに、それらの洗面台40、バスユニット50を床面材25の上に設置し、洗面台40、バスユニット50へのそれら配管類60の接続を完了するものとしている。
【0026】
そして、建物ユニット10にあっては、工場生産ラインでの配管類60の設置性を向上するため、配管パネル70を用い、それらの配管類60を以下の手順で設置するものである。
【0027】
(A)床構造体11の組立
(1)床構造体11を柱12、天井構造体13と接合して建物ユニット10を構成する前または後のいずれかの段階で、床構造体11の床面材取着領域のうちの一部を配管パネルセット用スペース26(配管パネル組込み用スペース)として予め定めて用意する。相対する桁床梁21、21の中間に中間梁21Aを設け、一方の桁床梁21と中間梁21Aとの間を配管パネルセット用スペース26とする(図4)。中間梁21Aの側面に配管パネル受用木桟21Bを取着しておく。
【0028】
(2)床構造体11の内部で、配管パネルセット用スペース26と、バスユニット50の設置領域を臨む床面材取着領域に床根太24を取着する(図5)。
【0029】

【0031】
(B)配管パネル70の組立
(1)配管パネル70を、床根太24に床面材25Cを取着し、相隣る床根太24の間に断熱材27を装填し、床根太24の裏面に地板29を取着して構成する(図7)。
【0032】
(2)配管パネル70を裏返しにして作業台等1の上に載せ、配管類60を床面材25Cの裏側で、床根太24に地板29を介して固定する。
【0033】
(3)配管類60は、給湯ヘッダ61と給水ヘッダ62を有し、給湯ヘッダ61に湯供給管61A、洗面台40への給湯管61B、バスユニット50への給湯管61C、上階への給湯管61Dを接続し、給水ヘッダ62に水供給管62A、洗面台40への給水管62B、バスユニット50への給水管62C、上階への給水管62Dを接続してある。
【0034】
なお、図1では、給湯管61C、給水管62Cのそれぞれから分岐したランドリー用の給湯管61E、給水管62Eも図示してある。そして、給湯ヘッダ61、給水ヘッダ62は、図8に示すように、Uバンド63などで床根太24に固定され、湯供給管61A、水供給管62A等はサドルバンド64等で床根太24に固定され、給湯管61B、給水管62B等は床面材25C、地板29に設けた孔65から床上に立ち上げ可能とされている。
【0035】

【0039】
(4)床構造体11の配管通管領域28に断熱材27、床面材25Dを取着する〔図9(C)〕。
【0040】
なお、建物ユニット10の組立工場では、建物ユニットの本体を組立てる主ラインの他にサブラインを用意し、床構造体11、配管パネル70をサブラインで組立てるか、あるいは別の組立工場で組立て、この床構造体11、配管パネル70を主ラインの横に待機させておくのが生産効率上、作業ミスを防ぐために適している。
【0041】
(D)建物ユニット10への洗面台40、バスユニット50のセット
(1)建物ユニット10の内部に洗面台40、バスユニット50を導入し、これらの洗面台40、バスユニット50を床構造体11の床面材25の上に据付ける。洗面台40に給湯管61B、給水管62Bを接続し、バスユニット50に給湯管61C、給水管62Cを接続する(図10)。
【0042】
(2)上階への給湯管61D、給水管62D等の配管類60を、建物ユニット10の床構造体11に上述の如くにセットした配管パネル70から壁パネル14の内部を通し、天井構造体13に仮固定する(図10)。
【0043】
なお、洗面台40、バスユニット50のセットは組立工場で行っても良く、建物ユニット10の据付現場で行なっても良い。
【0044】
上述のようにして製造された建物ユニット10は、工場から建築現場へ輸送され、予め構築された基礎の上に据付けられてユニット建物100を構成する。このとき、建物ユニット10の上に搭載される上階建物ユニット10Aに対し、図11に示すように、建物ユニット10の天井構造体13に仮固定してあった給湯管61D、給水管62Dなどの配管類60を立ち上げて上階建物ユニット10Aの内部へと延在せしめ、これらの配管類60を上階設備機器に接続する。
【0045】
また、建物ユニット10の横に設置される隣接建物ユニット10Bに対し、図12に示すように、両建物ユニット10、10Bに渡る湯供給管61A、水供給管62Aなどの配管類60は、両建物ユニット10、10Bのたとえば妻床梁22、22の下部で継手70を用いて接続される。
【0046】
従って、本実施形態によれば、以下の作用がある。
(1)配管パネル70は予め配管類60を設置されているから、建物ユニット10の床構造体11の少なくとも一部にセットされることにより、それらの床の内部への配管類60の配置固定を完了させることができる。
【0047】
(2)配管パネル70は、建物ユニット10の床構造体11の少なくとも一部にセットされる。従って、配管パネル70は、建物ユニット10の本来的構造要素であるその床構造体11の一部もしくは全部を構成するものであるから、構造強度的な余剰部分でなく、また建物の天井高等を減縮する要素にもならず、建物の構造上の合理性を損なうことがない。
【0048】
(3)配管パネル70は、床構造体11の少なくとも一部にセットされて用いられるものであり、建物ユニットに限らず、ユニット建物100でない一般建物への導入も容易である。
【0049】
(4)配管パネル70は、床構造体11の少なくとも一部にセットされるものであって小サイズ、軽量化でき、建物ユニット10のその床構造体11への組付性は良い。また、ユニット建物100の建築現場では、配管パネル70を組付けた建物ユニットの据付け以外に、配管パネル70を単独で組付ける必要がなく、建築現場での据付性も良い。
【0050】
(5)建物ユニット10の床構造体11に配管パネル70をセットすることにて配管類60を納めることができ、建物ユニットの工場生産ラインで、建物ユニットの内部から簡易に配管類60を設置できる。
【0051】
(6)配管パネル70が、床根太24に床面材25Cを取着してなり、配管類60を面材の裏側に置いて床根太24に固定したから、配管類60を強固に保持できる。
【0052】
(7)建物ユニット10の床構造体11において、配管パネルセット用スペース26を除く床面材取着領域に床面材25を取着した状態で、この配管パネルセット用スペース26に配管パネル70をセットする。従って、作業者は、床面材25の上に立つ安定した下向き姿勢で、配管類60の配置、固定を行なうことができ、床下作業や脚立作業を伴うことなく、配管類60の設置作業性を向上できる。
【0053】
(8)配管パネル70を建物ユニット10の床の上方から床の一部に組込むものであり、作業者は床の上から配管類を組込み作業でき、建物ユニット10の一連の組立工程で配管類60の設置作業性を向上できる。
【0054】
上記実施例では、建物ユニット10を構成している床構造体11の桁床梁21側に配管パネルセット用スペース26を設け、このスペース26内に配管パネル70を組み込んでセットするようにしたが、図13に示すように、建物ユニット10を構成している床構造体11の妻床梁22側に配管パネルセット用スペース26を設け、このスペース26内に配管パネル70を組み込んでセットするようにしてもよい。なお、この場合も、上記実施例と同様に、配管パネル70の床面材25Cの上には洗面台40が据付けられる。
【0055】
このように、床構造体11の妻床梁22側に、配管パネル70が組み込まれる配管パネルセット用スペース26を設けることにより、例えば、建物ユニット10の桁側に隣接して設置される隣接建物ユニット10Cに対し、図14に示すように、両建物ユニット10、10Cに渡る給湯管61C、給水管62Cなどの配管類60を、両建物ユニット10、10Cの桁床梁21、21の下部で継手70を用いて接続することができる。
【0056】
このため、建物ユニット10内にバスユニット50を据付けず、この建物ユニット10の桁側に隣接して設置される隣接建物ユニット10C内にバスユニット50を据付け、配管パネル70の給湯管61C、給水管62Cをバスユニット50に接続することができる。
【0057】
また、この場合も、上記実施例と同様に、床構造体11の所定部分に配管通管領域28を設けることにより、建物ユニット10の周りに隣接して設置される隣接建物ユニット内に据付けられる各種設備を配管パネル70の配管類60と接続することができる。
【0058】
以上、本発明の実施の形態を図面により詳述したが、本発明の具体的な構成はこの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更などがあっても本発明に含まれる。たとえば、本発明の実施において、配管パネルに設置される配管類は、配管に限らず、電気配線などの配線、床暖房装置や空調装置などの設備類も含む。
【0059】
また、配管類が設置される構造体は、床構造体に限らず、天井構造体、壁構造体であっても良い。
【0060】
また、配管類が設置される構造体は、建物ユニットや建物の構成部品(サブ組立体)としての、床パネル、天井パネル、壁パネルであっても良い。
【0061】
また、配管類が設置される構造体は、建物ユニットを構成するものに限らず、一般の建物を構成するものであっても良い。
【0062】
また、本発明により設置される配管類をさや管とし、さや管の内部に給水管や配線などを延在せしめることもできる。このさや管を用いた場合には、給水管や配線などの交換時に、さや管を交換する必要はなく、さや管が設置されている構造体の内部(床下など)に入ったり、それらの構造体を壊すことなく、給水管や配線などをさや管に対して出し入れすることにて交換できる。
【0063】
【発明の効果】
以上のように本発明によれば、ユニット建物などの建物において配管類を簡易、かつ、合理的に設置することができる。
