Description

【０００１】
【発明の属する技術分野】
本発明は、カーテンウォールに関し、特に室内側方立および室外側方立を組み合わせた複合方立を用いたカーテンウォールに関する。
【０００２】
【背景技術】
ビル等の外壁を構成するカーテンウォールは、通常、金属製の方立を用いて構成されていたが、室内意匠の向上を図るために木製の方立を用いたものが知られている（例えば、特許文献１，２）。
【０００３】
これらの先行技術のカーテンウォールは、木製の方立と、方立の一端面にその長軸方向に沿って装着された金属製下地材と、この金属製下地材に対し、方立の長軸方向に移動可能に装着された金属製取付具と、この金属製取付具に取り付けられたパネル材とを備えて構成され、金属製取付具と木製方立との熱伸縮差を吸収できるようにしている。
この際、前記金属製取付具を、金属製下地材に対して移動可能に装着するために、金属製下地材にその長軸方向に延びるスリットや長孔を形成し、スリットや長孔内にボルトを配置し、このボルトを前記金属製取付具を挟んで配置されたナットにねじ込み、このナットを締め付けて金属製下地材に対して固定すると共に、熱伸縮差が生じた際にはボルト部分がスリット内をスライド移動して吸収できるように構成していた。

【発明が解決しようとする課題】
しかしながら、前記先行技術の構造では、ボルトおよびナットの締め付け力を適切に設定しなければならず、施工作業が難しいという問題がある。すなわち、ボルトおよびナットの締め付け力が弱いと、金属製下地材に対して金属製取付具が下方に落下してしまい所定の位置に配置することができない。一方で、締め付け力が強すぎると、木製方立に対して金属製取付具が熱伸縮した際に、ボルトおよび金属製取付具が金属製下地材に強い力で圧接してしまい、スムーズにスライド移動させることができず、ボルトや金属製下地材に応力が加わったり、移動時に異音が発生したり、ボルト部分に振動が伝わってナットが緩んでしまうという問題があった。
このような問題は、室内側の木製方立および室外側の金属製取付具を備えて構成される方立に限らず、例えば、木粉が混入された樹脂材と金属材とを組み合わせた方立や、スチールとアルミニウムのように異種金属を組み合わせた方立のように、温度変化による熱伸び量が異なる異種材質の室内側および室外側の方立を組み合わせて構成された方立において、前記先行技術と同様に、ボルトおよびナットをスリット部分に配置して室内側方立に対し室外側方立をスライド移動可能に構成した場合にも発生していた。
【０００６】
本発明の目的は、室内側方立に対する室外側方立の熱伸縮によるスライド移動をスムーズに行え、異音の発生などを防止できるとともに、室内側方立および室外側方立の組み合わせ作業を容易に行うことができるカーテンウォールを提供することにある。
【０００７】
【課題を解決するための手段】
本発明のカーテンウォールは、複数の方立と、各方立間に架け渡される複数の無目と、方立および無目に端縁が保持された面材とを備えるカーテンウォールにおいて、前記方立は、室内側に配置された室内側方立と、室内側方立の室外側に取り付けられた室外側方立とを備え、前記室内側方立の室外側端面には、固定ガイド部材が上下方向に間隔を離して複数取り付けられ、前記室外側方立の室内側端部には、室外側方立の長手方向に沿って連続して形成され、かつ、少なくとも複数の固定ガイド部材に対し、上下方向にスライド移動可能かつ室内外方向および壁面に沿った横方向に移動不能に係合する係合部が設けられえ、前記室外側方立の係合部と、この係合部に係合している複数の固定ガイド部材のうちの１つの固定ガイド部材とを上下方向に移動不能に固定する固定手段を備えることを特徴とする。
【０００８】
ここで、壁面に沿った横方向（水平方向）とは、上下方向および室内外方向の２方向に直交する方向を意味する。また、固定ガイド部材が上下方向に間隔を離して複数取り付けられているとは、固定ガイド部材が室内側方立の長手方向つまり上下方向に一列に配置され、その際、各ガイド部材が間隔を離して取り付けられていることを意味する。
なお、固定ガイド部材および係合部の具体的形状は特に限定されないが、例えば、固定ガイド部材を断面略Ｔ字状に形成し、係合部を断面略コ字状に形成して係合するなど、係合部が固定ガイド部材に対して、三次元方向のうち、上下方向のみにスライド移動可能に係合されるような形状であればよい。
また、室内側方立および室外側方立の材質は、特に限定されないが、通常は以下のようなものが用いられる。例えば、室内側方立の材質としては、木製、木粉を混入した木粉入り合成樹脂製、アルミニウム製、スチール製、合成樹脂製等の各種材料が利用できる。さらには、例えばスチール製方立の表面に木製等の化粧板を貼付したものなど、複数の材質で構成されるものも利用できる。また、室外側方立の材質としても、アルミニウム製、スチール製、合成樹脂製等の各種材料が利用できる。これらは各方立に要求される性能やデザイン性等を考慮して適宜選定すればよい。
【０００９】
本発明では、方立を室内側方立および室外側方立で構成した際に、室内側方立に複数の固定ガイド部材を取り付け、これらの複数の固定ガイド部材に対して室外側方立を上下方向のみスライド移動可能に係合させるとともに、１つの固定ガイド部材に対しては、ボルトおよびナットなどの固定手段を用いて上下方向の移動もできないように固定している。従って、室外側方立が室内側方立に対して熱伸縮した場合に、室外側方立において固定手段で固定ガイド部材に固定された部分は移動できないが、他の部分は、固定ガイド部材に対して上下方向にはスライド移動可能に係合しているため、室外側方立がその長手方向に伸縮した際に、その伸縮による移動をスムーズに行うことができる。すなわち、本発明では、室外側方立を上下方向にガイドする機能は固定ガイド部材で実現し、室外側方立の上下位置を固定する機能は固定手段で実現することで各機能を分離しているので、先行技術のように、ボルト、ナットでスライド機能と固定機能とを兼用した場合のように、締付力を微妙に設定する必要が無く、施工作業を容易に行うことができる。その上、室外側方立が落下などすることもなくその高さ位置を正確に設定できるとともに、室外側方立が熱伸縮した際には、固定手段で固定された部分以外は、固定ガイド部材に対して自由にスライド可能なため、スムーズに移動でき、室外側方立や固定ガイド部材に無理な応力が加わることもなく、異音の発生なども防止できる。
【００１０】
本発明のカーテンウォールは、複数の方立と、各方立間に架け渡される複数の無目と、方立および無目に端縁が保持された面材とを備えるカーテンウォールにおいて、前記方立は、室内側に配置された室内側方立と、室内側方立の室外側に取り付けられた室外側方立とを備え、前記室内側方立の室外側端面には、上下方向に沿って連続し、かつ室外側に開口された凹溝が形成され、この凹溝の底面には固定ガイド部材が上下方向に間隔を離して複数取り付けられ、前記各固定ガイド部材は、前記底面に当接する当接部と、この当接部から前記底面と略平行な方向に突設されて前記底面との間に所定間隔の隙間を形成する突設部と、この突設部の両端からそれぞれ室外側に延長されて凹溝の側壁部分との間に所定間隔の隙間を形成する一対の延長部とを備えて構成され、前記室外側方立の室内側端部には、室外側方立の長手方向に沿って連続して形成され、かつ、少なくとも複数の固定ガイド部材に対し、上下方向にスライド移動可能かつ室内外方向および壁面に沿った横方向に移動不能に係合する係合部が設けられ、前記係合部は、前記固定ガイド部材の各延長部および凹溝の側壁部分との間の隙間に配置される一対の突出部と、各突出部から互いに近づく方向に突出されて固定ガイド部材の突設部と凹溝底面との間の隙間に配置される一対の係止部とを備えて構成され、室外側方立の係合部と、この係合部に係合している複数の固定ガイド部材のうちの１つの固定ガイド部材とを上下方向に移動不能に固定する固定手段を備えることを特徴とする。
【００１１】
本発明においても、前記発明と同じく、室外側方立が室内側方立に対して熱伸縮した場合に、室外側方立において固定手段で固定ガイド部材に固定された部分は移動できないが、他の部分は、固定ガイド部材に対して上下方向にはスライド移動可能に係合しているため、室外側方立がその長手方向に伸縮した際に、その伸縮による移動をスムーズに行うことができる。従って、本発明においても、室外側方立を上下方向にガイドする機能は固定ガイド部材で実現し、室外側方立の上下位置を固定する機能は固定手段で実現することで各機能を分離しているので、施工作業を容易に行うことができ、室外側方立の高さ位置を正確に設定できるとともに、室外側方立が熱伸縮した際には、固定手段で固定された部分以外は、固定ガイド部材に対して自由にスライド可能なため、スムーズに移動でき、室外側方立や固定ガイド部材に応力が無理な応力が加わることもなく、異音の発生なども防止できる。
さらに、固定ガイド部材が凹溝内に配置されており、固定ガイド部材と凹溝との隙間部分に、室外側方立の係合部を配置できるので、固定ガイド部材や係合部を室内側方立で被覆でき、意匠性を向上できる。
【００１２】
さらに、先行技術では、室内側方立の長手方向の全長に渡って金属製下地材を取り付けていたため、金属製下地材が室内側方立に対して熱伸縮すると、その伸縮に伴って下地材や室内側方立に応力が加わるおそれがある。これに対し、前記いずれの発明においても、固定ガイド部材は、室内側方立の長手方向の全長に渡って連続して設けられるものではなく、間隔を離して設けられた短尺のピース材であるため、仮に熱伸縮したとしてもその伸縮量は非常に小さく、応力の発生も防止できる。
なお、室外側方立の固定ガイド部材への固定箇所は、室外側方立の中間部分でもよいが、通常は、室外側方立の上端部分または下端部分のいずれか一方が好ましく、特に上端側を固定して室外側方立を吊り下げ支持することが好ましい。
【００１３】
ここで、本発明のカーテンウォールにおいて、室外側方立の係合部における一対の突出部と、固定手段によって室外側方立が固定される固定ガイド部材の一対の延長部とには貫通孔が形成され、前記凹溝の側壁には、前記固定ガイド部材の貫通孔を室内側方立の側面に露出させる切欠が形成され、前記固定手段は、この切欠部分から前記延長部および突出部の各貫通孔に挿通されるボルトと、このボルトに螺合されるナットとを備えて構成されていることが好ましい。
先行技術においては、前記ボルトへのナットの締め付けは、室外側から行う必要があるが、ボルトおよびナットの室外側には、通常、前記金属製取付具においてパネル板を保持する外押縁部材が配置されており、ナットの締め付け作業の作業性が低いという問題もある。
これに対し、本発明のように、前記延長部および突出部の貫通孔に挿通されるボルトは、室内側方立の側面側から挿入することができ、ナットの締め付け作業も室内側方立の側面側で行うことができるので、外押縁材等が設けられていても、ボルトおよびナットの締め付け作業を容易に行うことができる。
【００１４】
また、本発明のカーテンウォールにおいて、室外側方立の係合部における一対の係止部には、前記固定ガイド部材の幅寸法および高さ寸法よりも大きな開口が形成され、この開口内に前記固定ガイド部材が配置されるように室内側方立に対して室外側方立を横方向（水平方向）から移動させた後、室外側方立を上下方向に移動させることで固定ガイド部材に対し係合部が係合可能に構成されていることが好ましい。
【００１５】
室外側方立の係合部は、固定ガイド部材に対して上下方向つまり室内側方立の長手方向のみにスライド移動可能に係合されるため、通常は、室内側方立の小口側から室外側方立をスライド移動させなければならず、この場合、室外側方立の長さ寸法に室内側方立の長さ寸法を加えた作業スペースが必要となり、組立作業性が低いという問題がある。
これに対し、本願発明では、室内側方立の側面側から室外側方立をその長手方向直交方向（例えば方立を上下方向に立てた状態では水平方向）に移動し、係合部の切欠部分に固定ガイド部材を配置した後、室外側方立をその長手方向に僅かに移動することで係合できるので、作業効率が高く、かつ作業スペースも小さくすることができる。
【００１６】
【発明の実施の形態】
以下、本発明の各実施形態を図面に基づいて説明する。
図１は、本実施形態に係るカーテンウォール１の一部を示す概略外観図である。図２は、図１に示す矢視II−II線に沿った縦断面図、図３は、矢視III−III線に沿った横断面図である。
【００１７】
カーテンウォール１は、図１に示すように、建物の躯体間に複数配置された方立２と、各方立２間に架け渡された無目５と、前記方立２および無目５に端縁が保持された外壁パネル８とを備えて構成されている。
方立２は、室内側に配置された木製の室内側方立３と、室内側方立３の室外側に配置されたアルミニウム等の金属製の室外側方立４とで構成されている。
無目５は、室内側に配置された木製の室内側無目６と、室内側無目６の室外側に配置されたアルミニウム等の金属製の室外側無目７とで構成された無目５と、室外側無目７のみで構成された無目５とが用いられている。例えば、床や天井に近い位置に配置されて視認し難い箇所には、室外側無目７のみが用いられ、室内高さ方向の中間部分等の視認し易い箇所には、室内側無目６および室外側無目７で構成された無目５が用いられる。
【００１８】
室内側方立３の室外側端面には、図４にも示すように、方立３の長軸方向つまり上下方向に沿って連続する凹溝３１が形成されている。凹溝３１の底面（室外側端面）３１Ａには、凹溝３１の延長方向に沿った位置決め溝３２が形成されている。凹溝３１の側壁３３において、室外側方立４の上端部に対応する位置には、前記凹溝３１の底面３１Ａまで達する切欠３３Ａが形成されている。
なお、本実施形態では、図５，６に示すように、１本の室内側方立３に対して２本の室外側方立４が取り付けられているので、前記切欠３３Ａは、室内側方立３の上端部および中間部の２カ所に形成されている。
また、室内側方立３において、室内側無目６が配置される位置には、室内側無目６の端部が配置可能な凹部３４が形成されている。
室内側方立３の上下両端は、図示しない断面Ｌ字状のブラケットを用いて建物の躯体等に固定可能に構成されている。
【００１９】
凹溝３１には、複数の固定ガイド部材３５がコーチスクリュー（コーチスクリューボルト）３６等を用いてねじ止めされている。この固定ガイド部材３５は、断面形状が略Ｔ字状に形成され、かつ、中空筒状に形成されており、アルミ等の金属製の押出形材等を所定長さに切断することなどで構成されたピース材である。
より具体的に説明すると、固定ガイド部材３５は、凹溝３１の底面３１Ａに当接する当接部３５１と、当接部３５１から左右方向（壁面に沿った横方向）に突設、つまり前記底面３１Ａに略平行に突設された突設部３５２と、突設部３５２の両端から室外方向に延長された一対の延長部３５３と、各延長部３５３間を連結する連結部３５４とを備えて形成されている。
従って、突設部３５２および底面３１Ａ間と、各延長部３５３および側壁３３間には、それぞれ所定寸法の隙間が形成されている。
【００２０】
当接部３５１には、前記位置決め溝３２に係合する突起部が形成され、この突起部を前記位置決め溝３２に合わせることで固定ガイド部材３５の左右方向の位置決めを容易に行えるようになっている。
また、連結部３５４には、コーチスクリュー３６を挿通可能な孔３５４Ａが複数形成され、コーチスクリュー３６を用いて固定ガイド部材３５を取り付けた際に、コーチスクリュー３６の頭が前記中空部に収納されて連結部３５４から室外側に突出しないようにされている。
さらに、室外側方立４の上端位置に対応して配置される固定ガイド部材３５の各延長部３５３には、図６にも示すように、室外側方立４を固定するためのボルト１１を挿通可能な孔３５３Ａが形成されている。従って、固定ガイド部材３５としては、室外側方立４の上端位置に対応して配置されて室外側方立４を固定するための固定ガイド部材３５Ａと、室外側方立４の他の位置に配置されて室外側方立４を上下方向にスライド移動可能にかつ室内外方向および壁面に沿った横方向（左右方向）には移動不能にガイドする固定ガイド部材３５Ｂとが設けられている。
【００２１】
なお、本実施形態では、図４に示すように、室内側方立３に対して５個の固定ガイド部材３５が取り付けられ、これらの固定ガイド部材３５によって２本の室外側方立４が取り付けられている。そして、上から３個目の固定ガイド部材３５は、各室外側方立４に跨って配置可能なように、他の固定ガイド部材３５よりも上下方向の長さ寸法が大きくされている。この固定ガイド部材３５は、下側に配置される室外側方立４に対してはボルト１１で固定されるため、固定用の固定ガイド部材３５Ａとして機能する。一方で、上側に配置される室外側方立４に対しては、ボルト１１では固定されていないので、ガイド用の固定ガイド部材３５Ｂとして機能する。
なお、固定ガイド部材３５の個数は、５個に限定されず、少なくとも各室外側方立４に対して２個以上の固定ガイド部材３５が係合するように配置されていればよい。実際には、カーテンウォール１に加わる耐風圧方向の荷重支持強度等に基づいて設定すればよい。
【００２２】
室外側方立４は、前記固定ガイド部材３５に係合する係合部４４を備えた室内側部材４１と、外壁パネル８の室外側に配置されるフランジ部分を備えて外押縁材として機能する室外側部材４２と、これらの各部材４１，４２を連結する連結材４３とで構成され、全体の断面形状が略Ｔ字状に形成されている。室内側部材４１、室外側部材４２は、アルミ等の金属材であり、連結材４３は樹脂等の断熱性部材で構成され、室外側に露出する室外側部材４２から室内側部材４１への熱伝導を抑えて断熱性能に優れた室外側方立４とされている。
【００２３】
室内側部材４１の室内端部には、断面略コ字状の係合部４４が形成されている。すなわち、係合部４４は、図３に示すように、室内側部材４１の本体から前記連結部３５４に沿って左右方向に延長された延長部４４１と、延長部４４１の両端から室内方向に突出されて各延長部３５３に沿って配置され、各延長部３５３と側壁３３との間の隙間に配置される突出部４４２と、各突出部４４２から互いに近づく方向に突出されて前記各突設部３５２と底面３１Ａとの間の隙間に配置される係止部４４３とを備えて構成されている。
従って、室外側方立４の係合部４４は、前記固定ガイド部材３５に対して室内外方向および壁面に沿った横方向（左右方向、見付け方向）に移動不能に、かつ、上下方向（方立２の長軸方向）にスライド移動可能に係合している。
【００２４】
さらに、係合部４４の係止部４４３は、図７に示すように、その所定箇所に切欠４４３Ａが形成されている。この切欠４４３Ａの幅寸法は、前記固定ガイド部材３５の幅寸法よりも大きく、かつ、高さ寸法（上下方向の寸法）は、各固定ガイド部材３５の高さ寸法よりも大きくされている。
このため、図５，８に示すように、切欠４４３Ａの高さ位置を、各固定ガイド部材３５の高さ位置に合わせた状態で、各固定ガイド部材３５を凹溝３１内に移動させて各固定ガイド部材３５を切欠４４３Ａ内に配置し、その状態で室外側方立４を上下方向にスライド移動させることで、係合部４４を各固定ガイド部材３５に係合させることができる。
従って、各切欠４４３Ａの形成位置は、その切欠４４３Ａに配置される各固定ガイド部材３５の取り付け位置に応じて設定されている。
なお、本実施形態では、上側の室外側方立４は、室内側方立３に対して上側にずらした位置で前記切欠４４３Ａ内に各固定ガイド部材３５を配置し、その後、下方にスライド移動させるように構成され、下側の室外側方立４は、室内側方立３に対して下側にずらして位置で前記切欠４４３Ａに各固定ガイド部材３５を配置し、その後、上方にスライド移動させるように構成されている。従って、室内側方立３に対する取付順序は、どちらを先にすることもでき、取付作業性に優れている。
【００２５】
各室外側方立４の係合部４４の上端部において、各突出部４４２には、各固定ガイド部材３５の孔３５３Ａに対応した位置に貫通孔４４２Ａが形成されている。従って、係合部４４を各固定ガイド部材３５に係合させた後、図６に示すように、各孔４４２Ａ、３５３Ａを挿通させたボルト１１にナット１２を螺合することで、各室外側方立４の上端部が各固定ガイド部材３５つまり室内側方立３に上下方向移動不能に固定されている。
一方、各室外側方立４の中間部や下端部側は、各固定ガイド部材３５に対し上下方向のみはスライド移動可能に係合しているので、各室外側方立４は室内側方立３に対してスムーズに熱伸縮できるように構成されている。
【００２６】
室内側方立３および各室外側方立４で構成される方立２間には、無目５が掛け渡されている。
【００２７】
室外側無目７は、図２に示すように、金属製の室内側部材７１および室外側部材７２と、断熱材で構成された連結材７３で構成された室外側方立４と同様な断熱形材で構成されている。そして、外壁パネル８の下端縁をシーリング材、バックアップ材を介して保持可能に構成されている。
また、室外側部材７２には、室外側部材７２と共に、外壁パネル８の上端縁を保持する外押縁材７５が着脱可能に取り付けられている。
この室外側無目７は、例えば、図２，３に示すように、室外側方立４の側面に固定されたＬ字状の支持ブラケット４６に、室内側部材７１の中空部分を載置することなどで取り付けられている。一方、室内側無目６は、その両端部を室内側方立３の凹部３４に挿入することで取り付けられている。
【００２８】
また、室外側方立４には、室外側部材４２のフランジとともに、外壁パネル８の両側端縁を保持する内押縁材４７が着脱自在に取り付けられている。
【００２９】
このような本実施形態においては、次のような手順でカーテンウォール１を構築する。
まず、図４に示すように、室内側方立３に各固定ガイド部材３５をコーチスクリュー３６を用いて固定する。次に、図５，８に示すように、室外側方立４を各固定ガイド部材３５に係合させる。この際、前記切欠４４３Ａに各固定ガイド部材３５を配置することで、室外側方立４を各固定ガイド部材３５の小口側からスライドさせることなく、取り付けることができる。なお、各室外側方立４に跨って配置される固定ガイド部材３５に対応する切欠４４３Ａは形成されていないが、図８に示すように、他の固定ガイド部材３５に対応する高さ位置に切欠４４３Ａを配置した際には、各室外側方立４は、前記真ん中の固定ガイド部材３５から外れた位置に配置されるように設計し、切欠４４３Ａを不要としているためである。
【００３０】
次に、各室外側方立４を固定ガイド部材３５に係合させた後、ボルト１１およびナット１２を用いて各室外側方立４の上端部を固定ガイド部材３５にボルト止めする。この際、室外側方立４の中間部および下端部は、固定ガイド部材３５に対し上下方向のみスライド移動可能に係合している。従って、室外側方立４が室内側方立３に対して熱伸縮した場合には、室外側方立４の下端部が上下にスライド移動することで吸収できるようになっている。
【００３１】
このように構成された方立２を左右方向に所定間隔離して配置し、各方立２間に室内側無目６、室外側無目７を掛け渡して取り付けると共に、方立２を建物躯体などに固定する。
方立２および無目５を枠組み固定した後、外壁パネル８を配置し、内押縁材４７、外押縁材７５を取り付け、バックアップ材、シーリング材を配置して外壁パネル８を固定する。
以上により、カーテンウォール１が構成される。
【００３２】
このような本実施形態によれば、以下のような効果がある。
(1) 室内側方立３および室外側方立４を連結するにあたって、室外側方立４の係合部４４を複数の固定ガイド部材３５に対してスライド移動可能に係合するとともに、その内の１つの固定ガイド部材３５のみに対し、固定手段であるボルト１１およびナット１２でスライド移動不能に固定し、スライド移動と固定とを別々の部材で構成したので、ボルト、ナットでスライド機能と固定機能とを兼用した場合のように、締付力を微妙に設定する必要が無く、施工作業を容易に行うことができる。
その上、ボルト１１、ナット１２によって室外側方立４を確実に支持できて、その高さ位置がずれることも防止でき、室外側方立４が熱伸縮した際には、ボルト１１等で固定されていない他の固定ガイド部材３５に対しては、係合部４４は何ら規制されることなく、自由にスライド移動できるため、室外側方立４や固定ガイド部材に無理な応力が加わることもなく、異音の発生なども防止できる。
【００３３】
(2) 固定ガイド部材３５は室内側方立３の凹溝３１内に配置されているので、固定ガイド部材３５および係合部４４を室内側方立３の側壁３３で被覆することができ、方立２の内観意匠を向上できる。
【００３４】
(3) 室内側方立３に固定される固定ガイド部材３５は、短尺のピース材で構成しているので、仮に熱伸縮したとしてもその伸縮量は非常に小さく、応力の発生も防止できる。
固定ガイド部材３５は、中空筒状に形成されているので、コーチスクリュー３６の頭を収納できるとともに、固定ガイド部材３５の強度を向上でき、外壁パネル８に加わる風圧を十分に支持することができる。
【００３５】
(4) ボルト１１およびナット１２の挿入、締付作業を、室内側方立３の側面側から行うことができるので、室外側部材４２のフランジ部分が作業の邪魔になることもなく、ボルト１１およびナット１２の締め付け作業を容易に行うことができる。
【００３６】
(5) 室外側方立４の係合部４４に、固定ガイド部材３５を挿入可能な切欠４４３Ａを形成したので、室内側方立３の側面側から室外側方立４を固定ガイド部材３５に向かって移動し、切欠４４３Ａ部分に固定ガイド部材３５を配置した後、室外側方立４をその長手方向に僅かに移動することで係合でき、作業効率が高く、かつ作業スペースも小さくすることができる。
【００３７】
なお、本発明は、前記実施形態に限定されるものではない。
例えば、前記実施形態では、係合部４４に切欠４４３Ａを形成していたが、この切欠４４３Ａを設けなくてもよい。但し、この場合、室外側方立４を室内側方立３の小口側から挿入しなければならないため、切欠４４３Ａを設けた方が、作業効率を向上できて作業スペースも小さくできる点で好ましい。
【００３８】
室外側方立４を固定ガイド部材３５に固定する固定手段としては、ボルト１１およびナット１２に限らず、例えば、固定ガイド部材３５から突出するピンを係合部４４の各孔４４２Ａに嵌合させる構成など、他の固定手段を用いてもよい。要するに、室外側方立４を固定ガイド部材３５に対して上下方向に移動不能に固定できればよい。
【００３９】
また、前記実施形態では、凹溝３１内に固定ガイド部材３５を配置していたが、凹溝３１を無くして室内側方立３の室外側端面に固定ガイド部材３５を配置してもよい。
さらに、固定ガイド部材３５の断面形状および係合部４４の断面形状は、前記実施形態のものに限られず、例えば、固定ガイド部材３５においては、連結部３５４を無くしてもよく、要するに、互いに上下方向のみ移動可能に係合される形状であればよい。
室内側方立３および室外側方立４の材質は前記実施形態に限らない。例えば、室内側方立３は、木製方立に限らず、木粉入り樹脂、スチール、合成樹脂等の各種材質のものが利用できる。同様に、室外側方立４の材質も、アルミニウムに限らず、他の金属材料や合成樹脂等の各種材質のものが利用できる。
【００４０】
【発明の効果】
以上に述べたように、本発明のカーテンウォールによれば、室内側方立の室外側に装着された金属材の熱伸縮によるスライド移動をスムーズに行え、異音の発生などを防止できるとともに、金属材の装着作業を容易に行うことができるという効果がある。

BACKGROUND OF THE INVENTION
The present invention relates to a curtain wall, and more particularly, to a curtain wall using a composite stand that combines an indoor side stand and an outdoor side stand.
[0002]
[Background]
Curtain walls that make up the outer walls of buildings and the like are usually constructed using metal verticals, but those using wooden verticals are known in order to improve indoor design (for example, Patent Documents 1, 2).
[0003]
These prior art curtain walls consist of a wooden stand, a metal base attached to one end face of the stand along the long axis direction, and a long axis of the stand against the metal base. It is composed of a metal fixture movably mounted in the direction and a panel material attached to the metal fixture, so that the thermal expansion and contraction difference between the metal fixture and the wooden stand can be absorbed. ing.
At this time, in order to movably attach the metal fixture to the metal base material, a slit or a long hole extending in the long axis direction is formed in the metal base material, and the slit or the long hole is formed in the slit or the long hole. A bolt is placed, and the bolt is screwed into a nut placed with the metal fixture in between. The nut is tightened and fixed to the metal base material. Was configured to be able to absorb by sliding in the slit.

[0005]
[Problems to be solved by the invention]
However, the prior art structure has a problem that the tightening force of the bolts and nuts must be set appropriately, and the construction work is difficult. That is, if the tightening force of the bolts and nuts is weak, the metal fixture will drop downward with respect to the metal base material and cannot be placed at a predetermined position. On the other hand, if the tightening force is too strong, when the metal fixture thermally expands and contracts against the wooden stand, the bolt and the metal fixture are pressed against the metal base material with a strong force and slide smoothly. There is a problem that the bolt cannot be moved, stress is applied to the bolt or the metal base material, abnormal noise is generated during the movement, or vibration is transmitted to the bolt portion to loosen the nut.
Such a problem is not limited to a wooden stand provided with an indoor wooden stand and an outdoor metal fixture. For example, a combination of a resin material mixed with wood powder and a metal material. In the upright or the upright constructed by combining the indoor and outdoor uprights of dissimilar materials having different thermal expansion amounts due to temperature changes, such as the uprights that are made of different metals such as steel and aluminum, Similar to the prior art, it also occurred when the bolts and nuts were arranged in the slit portion so that the outdoor side stand was slidable relative to the indoor side stand.
[0006]
The purpose of the present invention is to enable smooth sliding movement by thermal expansion / contraction of the outdoor side stand with respect to the indoor side stand, prevent the generation of abnormal noise, etc., and facilitate the combination work of the indoor side stand and the outdoor side stand. It is to provide a curtain wall that can be performed.
[0007]
[Means for Solving the Problems]
The curtain wall according to the present invention is a curtain wall comprising a plurality of vertices, a plurality of meshes spanned between the vertices, and a face material in which the edges are held on the vertices and the meshes. The stand includes an indoor side stand disposed on the indoor side and an outdoor side stand attached to the outdoor side of the indoor side stand. A fixed guide member is provided on the outdoor side end surface of the indoor side stand. A plurality of attachments are provided at intervals in the vertical direction, and are formed continuously at the indoor side end of the outdoor side standing along the longitudinal direction of the outdoor side standing, and at least with respect to a plurality of fixed guide members An engaging portion that is slidable in the vertical direction and that is immovable in the indoor and outdoor direction and in the lateral direction along the wall surface is provided. One fixed guide member of the plurality of fixed guide members Characterized in that it comprises a fixing means for immovably fixed direction.
[0008]
Here, the horizontal direction (horizontal direction) along the wall surface means a direction orthogonal to the two directions of the vertical direction and the indoor / outdoor direction. In addition, a plurality of fixed guide members are attached at intervals in the vertical direction. The fixed guide members are arranged in a row in the longitudinal direction of the indoor side, that is, in the vertical direction. It means that it is attached separately.
The specific shapes of the fixed guide member and the engaging portion are not particularly limited. For example, the fixed guide member is formed in a substantially T-shaped cross section, and the engaging portion is formed in a substantially U-shaped cross section to be engaged. For example, the engaging portion may be configured to be slidably engaged with the fixed guide member only in the vertical direction in the three-dimensional direction.
Moreover, although the material of the indoor side standing and the outdoor side standing is not particularly limited, the following materials are usually used. For example, various materials such as wood, synthetic resin containing wood flour mixed with wood flour, aluminum, steel, synthetic resin, etc. can be used as the material of the indoor side standing. Furthermore, for example, a structure made of a plurality of materials such as a wooden decorative plate attached to the surface of a steel vertical can be used. Also, various materials such as aluminum, steel, synthetic resin, etc. can be used as the outdoor standing material. These may be appropriately selected in consideration of performance and design required for each side.
[0009]
In the present invention, when the vertical is composed of the indoor side standing and the outdoor side standing, a plurality of fixed guide members are attached to the indoor side standing and the outdoor side standing is set to the plurality of fixed guide members. It is engaged so as to be slidable only in the vertical direction, and is fixed to one fixed guide member so that it cannot be moved in the vertical direction by using fixing means such as bolts and nuts. Therefore, when the outdoor side stand thermally expands and contracts with respect to the indoor side stand, the part fixed to the fixed guide member by the fixing means in the outdoor side stand cannot move, but the other part is fixed to the fixed guide member. On the other hand, since it is slidably engaged in the up-and-down direction, when the outdoor side stand extends and contracts in the longitudinal direction, the movement by the expansion and contraction can be performed smoothly. That is, in the present invention, the function of guiding the outdoor side upright in the vertical direction is realized by the fixed guide member, and the function of fixing the vertical position of the outdoor side vertical is realized by the fixing means to separate each function. Therefore, unlike the prior art, it is not necessary to set the tightening force delicately as in the case where the sliding function and the fixing function are combined with bolts and nuts, and the construction work can be easily performed. In addition, the height of the outdoor side stand can be accurately set without dropping, and when the outdoor side stand is thermally expanded and contracted, the fixed guide member except for the portion fixed by the fixing means Therefore, it is possible to move smoothly, without applying excessive stress to the outdoor side stand or the fixed guide member, and to prevent the generation of abnormal noise.
[0010]
The curtain wall according to the present invention is a curtain wall comprising a plurality of vertices, a plurality of meshes spanned between the vertices, and a face material in which the edges are held on the vertices and the meshes. The upright includes an indoor side stand disposed on the indoor side and an outdoor side stand attached to the outdoor side of the indoor side stand, and the outdoor side end surface of the indoor side stand extends in the vertical direction. And a plurality of fixed guide members are attached to the bottom surface of the concave groove at intervals in the vertical direction, and each of the fixed guide members contacts the bottom surface. A contact portion that comes into contact with, a projecting portion that protrudes from the contact portion in a direction substantially parallel to the bottom surface and forms a gap of a predetermined distance from the bottom surface, and a chamber from each end of the projecting portion. A pair of extensions that extend outward to form a gap at a predetermined distance from the side wall portion of the groove. And is formed continuously along the longitudinal direction of the outdoor side stand, and at least a plurality of fixed guide members in the vertical direction. Engaging portions that are slidably movable and engage in an immovable manner in the indoor / outdoor direction and in the lateral direction along the wall surface are provided, and the engaging portions include the extended portions of the fixed guide member and the side wall portions of the concave grooves. A pair of protrusions arranged in a gap between the pair of protrusions, and a pair of locking parts protruding in a direction approaching each other from the protrusions and arranged in a gap between the protruding portion of the fixed guide member and the bottom surface of the groove And a fixed guide member out of a plurality of fixed guide members engaged with the engaging portion is fixed in a vertically immovable manner. A fixing means is provided.
[0011]
Also in the present invention, as in the case of the above invention, when the outdoor side stand is thermally expanded and contracted with respect to the indoor side stand, the portion fixed to the fixed guide member by the fixing means in the outdoor side stand cannot move. Since this part is engaged with the fixed guide member so as to be slidable in the vertical direction, when the outdoor side stand extends and contracts in the longitudinal direction, the movement by the expansion and contraction can be performed smoothly. . Therefore, also in the present invention, the function of guiding the outdoor side upright in the vertical direction is realized by the fixed guide member, and the function of fixing the vertical position of the outdoor side vertical is realized by the fixing means to separate each function. Therefore, construction work can be done easily, the height position of the outdoor stand can be set accurately, and when the outdoor stand is thermally expanded and contracted, the parts other than those fixed by the fixing means Since it is freely slidable with respect to the fixed guide member, it can move smoothly, no stress is applied to the outdoor stand or the fixed guide member, and the generation of abnormal noise can be prevented.
Furthermore, since the fixed guide member is disposed in the recessed groove, and the engaging portion of the outdoor side standing can be disposed in the gap portion between the fixed guide member and the recessed groove, the fixed guide member and the engaging portion are disposed on the indoor side. It can be coated in a vertical direction and the design can be improved.
[0012]
Furthermore, in the prior art, since the metal base material is attached over the entire length in the longitudinal direction of the indoor side stand, when the metal base material is thermally expanded and contracted with respect to the indoor side stand, the base material is accompanied with the expansion and contraction. There is a risk of stress being applied to the side walls of the room. On the other hand, in any of the above-mentioned inventions, the fixed guide member is not provided continuously over the entire length in the longitudinal direction of the indoor side erection, but is a short piece material provided at an interval. Therefore, even if thermal expansion / contraction occurs, the amount of expansion / contraction is very small, and the generation of stress can be prevented.
The fixed portion of the outdoor side stand to the fixed guide member may be an intermediate portion of the outdoor side stand, but usually, either the upper end portion or the lower end portion of the outdoor side stand is preferable, and the upper end side is particularly preferable. It is preferable to suspend and support the outdoor stand.
[0013]
Here, in the curtain wall of the present invention, there are through holes in the pair of projecting portions in the engaging portion of the outdoor side standing and the pair of extending portions of the fixed guide member to which the outdoor side standing is fixed by the fixing means. A notch is formed in the side wall of the recessed groove to expose the through hole of the fixed guide member on the side wall of the indoor side, and the fixing means is provided with each of the extension and the protrusion from the notch It is preferable to include a bolt inserted through the through hole and a nut screwed into the bolt.
In the prior art, it is necessary to tighten the nut to the bolt from the outdoor side. However, an outer edge member for holding the panel plate in the metal fixture is usually arranged on the outdoor side of the bolt and nut. There is also a problem that the workability of the nut tightening work is low.
On the other hand, as in the present invention, the bolt inserted through the through hole of the extension part and the protruding part can be inserted from the side surface side of the indoor side upright, and the tightening operation of the nut is also performed indoor side upright. Since it can be performed on the side surface side, the bolts and nuts can be easily tightened even if an outer edge material or the like is provided.
[0014]
Further, in the curtain wall of the present invention, an opening larger than the width dimension and the height dimension of the fixed guide member is formed in the pair of engaging portions in the engaging portion of the outdoor standing side, and the opening is formed in the opening. After the outdoor side stand is moved from the horizontal direction (horizontal direction) with respect to the indoor side stand so that the fixed guide member is disposed, the outdoor side stand is moved in the vertical direction with respect to the fixed guide member. It is preferable that the engaging portion is configured to be engageable.
[0015]
Since the engaging portion of the outdoor side standing is engaged with the fixed guide member so as to be slidable only in the vertical direction, that is, the longitudinal direction of the indoor side standing, the chamber is usually provided from the small side of the indoor side standing. In this case, a work space in which the length of the outdoor side stand is added to the length of the indoor side stand is required, resulting in low assembly workability. .
On the other hand, in the present invention, the outdoor side stand is moved from the side surface side of the indoor side stand in the direction orthogonal to the longitudinal direction (for example, the horizontal direction when the stand is set up and down), and the notch of the engaging portion is After the fixed guide member is disposed in the portion, the outdoor stand can be engaged by slightly moving in the longitudinal direction, so that the working efficiency is high and the working space can be reduced.
[0016]

According to this embodiment, there are the following effects.
(1) When connecting the indoor side stand 3 and the outdoor side stand 4, the engaging portion 44 of the outdoor side stand 4 is slidably engaged with the plurality of fixed guide members 35, Since only one fixed guide member 35 is fixed with the bolt 11 and the nut 12 which are fixing means so as not to be slidable, and the sliding movement and fixing are configured as separate members, the sliding function and fixing with the bolt and nut are provided. Unlike the case where the function is also used, it is not necessary to set the tightening force delicately, and the construction work can be easily performed.
In addition, the outdoor stand 4 can be reliably supported by the bolt 11 and the nut 12, and the height position can be prevented from shifting. When the outdoor stand 4 is thermally expanded and contracted, it is fixed with the bolt 11 or the like. For the other fixed guide members 35 that are not provided, the engaging portion 44 is freely slidable without any restriction, so that excessive stress may be applied to the outdoor stand 4 or the fixed guide member. In addition, abnormal noise can be prevented.
[0033]
(2) Since the fixed guide member 35 is disposed in the concave groove 31 of the indoor side stand 3, the fixed guide member 35 and the engaging portion 44 can be covered with the side wall 33 of the indoor side stand 3, The interior design of the vertical 2 can be improved.
[0034]
(3) Since the fixed guide member 35 fixed to the indoor side stand 3 is composed of a short piece material, even if it is thermally expanded and contracted, its expansion / contraction amount is very small, and generation of stress can be prevented.
Since the fixed guide member 35 is formed in a hollow cylindrical shape, the head of the coach screw 36 can be accommodated, the strength of the fixed guide member 35 can be improved, and the wind pressure applied to the outer wall panel 8 can be sufficiently supported. .
[0035]
(4) Since the bolts 11 and nuts 12 can be inserted and tightened from the side of the indoor side stand 3, the flange portion of the outdoor member 42 does not interfere with the work, and the bolt 11 The nut 12 can be easily tightened.
[0036]
(5) Since the notch 443A into which the fixed guide member 35 can be inserted is formed in the engaging portion 44 of the outdoor side stand 4, the outdoor side stand 4 is connected to the fixed guide member 35 from the side surface side of the indoor side stand 3. After moving toward the notch 443A, the stationary guide member 35 is arranged, and then the outdoor side stand 4 can be engaged by slightly moving in the longitudinal direction, so that the work efficiency is high and the work space is also reduced. Can do.
[0037]
The present invention is not limited to the above embodiment.
For example, in the embodiment described above, the notch 443A is formed in the engaging portion 44, but the notch 443A may not be provided. However, in this case, since the outdoor side stand 4 must be inserted from the small opening side of the indoor side stand 3, it is preferable to provide the notch 443A because the work efficiency can be improved and the work space can be reduced.
[0038]
The fixing means for fixing the outdoor side stand 4 to the fixed guide member 35 is not limited to the bolt 11 and the nut 12. For example, a pin protruding from the fixed guide member 35 is fitted in each hole 442 A of the engaging portion 44. Other fixing means such as a configuration may be used. In short, it suffices that the outdoor side stand 4 can be fixed to the fixed guide member 35 so as not to move in the vertical direction.
[0039]
In the above embodiment, the fixed guide member 35 is disposed in the recessed groove 31. However, the fixed guide member 35 may be disposed on the outdoor side end surface of the indoor side stand 3 without the recessed groove 31.
Further, the cross-sectional shape of the fixed guide member 35 and the cross-sectional shape of the engaging portion 44 are not limited to those of the above-described embodiment. For example, in the fixed guide member 35, the connecting portion 354 may be omitted. Any shape can be used as long as it can be moved only in the direction.
The material of the indoor side stand 3 and the outdoor side stand 4 is not limited to the above embodiment. For example, the indoor side stand 3 is not limited to a wooden stand but may be made of various materials such as resin containing wood powder, steel, and synthetic resin. Similarly, the material of the outdoor side stand 4 is not limited to aluminum, and various materials such as other metal materials and synthetic resins can be used.
