Description

【０００１】
【発明の属する技術分野】
この発明に係る壁構造体は、病院、公民館、庁舎等、各種建造物のロビーやホール等の屋内空間と屋外空間とを仕切ると共に、この屋内空間に外光を取り入れる採光壁として利用する。特に本発明の壁構造体は、採光用のガラスパネルの四辺を支持する方立や無目のうちで上記屋内空間に露出する部分を、木材等の非金属材料により覆う事で、屋内空間にいる者に無機質な感じを与えない様にする構造の改良に関する。
【０００２】
【従来の技術】
各種建造物のロビーやホール等の屋内空間と屋外空間とを仕切ると共に、この屋内空間に外光を取り入れる採光壁で、この屋内空間に露出する部分を木材製とし、屋内空間にいる者に無機質な感じを与えない様にする構造が、特許文献１に記載されて従来から知られている。この特許文献１に記載された構造は、図１５に示す様に、木製の支柱１の屋外側面に方立２を結合固定し、この方立２或は図示しない竪枠と、図示しない無目或は上下枠とにより、複数枚のガラスパネル３、３の四辺を支持している。この様な構造の場合には、上記屋内空間には、上記木製の支柱１が露出し、アルミニウム合金の押し出し型材製の上記方立２等は露出しないので、上記屋内空間にいる者に無機質な感じを与える事がない。
【０００３】
【特許文献１】
特許第２７６６２２１号公報
【０００４】
【発明が解決しようとする課題】
上述の様な特許文献１に記載された従来構造の場合、木製の支柱１が強度部材であって、この支柱１により、方立２及び無目の他、複数枚のガラスパネル３、３の重量を支えている。これに対して木材は、鉄鋼等の金属材料に比べて、ヤング率を初めとする機械的強度が低い。この為、大型の壁構造体を構成する場合には、上記支柱１の断面積を相当に広くする必要が生じる。この支柱１の断面積を広くする事は、その分だけ、上記各ガラスパネル３、３の面積及び床面積が狭くなる事に繋がり、室内空間にいる者に重苦しい感じを与え易くなる等、意匠的に好ましくない場合が多い。
【０００５】
又、意匠的に好ましい外観を有し、しかも、十分な強度を有する支柱１を木材のみにより造ると、例え間伐材を利用した集成材としたとしても、相当にコストが嵩む事が避けられない。しかも、木材は傷付き易く、長期間に亙る使用時には、何らかの硬い物がぶつかったりして、表面が傷付く可能性が高い。この様な場合に、強度部材である支柱１全体が木製であると、傷付いた支柱１のみを交換する事は非常に難しい。仮に傷付いた支柱１のみを交換できたとしても、交換に要するコストは極めて高くなる。従って、表面の傷は、現場作業で補修しなければならず、コストが嵩む。
本発明は、この様な事情に鑑みて、建設コスト自体を低く抑えられる他、表面が傷付いた場合の修理、交換に要するコストも低く抑える事ができ、しかも好ましい意匠を実現し易い壁構造体を提供すべく発明したものである。
【０００６】
【課題を解決するための手段】
本発明の壁構造体は、従来から知られている壁構造体と同様に、それぞれ複数ずつの方立と無目とを互いに交差する方向に組み合わせ、これら方立と無目とにより複数枚のパネルを支持すると共に、これら各方立の屋内側に、これら方立と無目とパネルとを支える為の複数本の支柱を設けている。
特に、本発明の壁構造体に於いては、これら各支柱を、上記各方立の屋内側に結合固定され、上下両端部をそれぞれ固定部分に対し結合固定される、金属製の支柱本体と、それぞれ少なくとも表面が非金属材製で、組み合わされた状態で上記支柱本体を覆う複数の化粧材とにより構成している。
【０００７】
【作用】
上述の様に構成する本発明の壁構造体の場合には、構成各部材の重量を支える支柱本体が金属製である為、この支柱本体の断面積をあまり大きくする事なく、十分な強度を確保できる。この為、化粧材を含んだ状態でも、支柱の幅寸法を小さくできて、パネルの面積を広くし易くなる等、好ましい意匠を実現する事に関する自由度が向上する。
【０００８】
又、化粧材は、単に上記金属製の支柱本体を覆えれば良い為、厚さ寸法は小さくて良い。従って、上記化粧材を木製とする場合でも、この化粧材のコストを低く抑える事ができる。更には、上記支柱本体からこの化粧材を取り外しても、上記パネルの支持には何ら影響しない為、傷んだ化粧材のみの修理、交換を容易に行なえる。従って、この修理、交換に要するコストも、低く抑える事ができる。
【０００９】
【発明の実施の形態】
図１〜１３は、本発明の実施の形態の第１例を示している。図１は、本例の壁構造体４を屋外側から見た状態を示している。この壁構造体４は、それぞれが鉛直方向に配設された、左右１対の堅枠４３、４３と、複数本（図示の例では３本）の方立２ａ、２ａを有する。これら各堅枠４３、４３及び各方立２ａ、２ａの屋内側には、図３、８に詳示する様に、本発明の特徴部分である支柱１ａを結合固定している。この支柱１ａ部分の構造に就いては、後で詳しく述べる。又、上記各堅枠４３、４３及び上記各方立２ａ、２ａの上端部は図４に示す様に天井面５に、同じく下端部は図５に示す様に床面６に、それぞれ結合固定している。この結合固定部分の構造に就いても、後で詳しく述べる。更に、隣り合う堅枠４３、４３及び方立２ａ、２ａ同士の間には、上端部に上枠７を、下端部に下枠８を、中間部に無目９、９を、それぞれ複数本ずつ（図示の例では合計で６本ずつ）掛け渡している。そして、これら上枠７、下枠８、各無目９、９と上記各堅枠４３、４３及び方立２ａ、２ａとにより、複数枚のガラスパネル３、３の四辺を支持している。尚、上記各堅枠４３、４３と、上記各方立２ａ、２ａとの相違は、上記各ガラスパネル３、３を片側にのみ（堅枠４３、４３の場合）設けるか、両側に（方立２ａ、２ａの場合）設けるかが相違する以外、基本的には同じ構造で、他の部分と組み合わされる。
【００１０】
尚、これら各ガラスパネル３、３の四辺を支持する部分の構造に就いては、図３〜６に具体的に示しているが、従来から広く知られており、本発明の要旨とも関係しない為、詳しい説明は省略する。又、図示の例では、上記上枠７、７、下枠８、８、各無目９、９及び上記各堅枠４３、４３、各方立２ａ、２ａとして、それぞれがアルミニウム合金の押し出し型材製である屋外側半片と屋内側半片とを、優れた熱絶縁性を有する合成樹脂により結合した、所謂断熱サッシとしている。この様な断熱サッシの構造及び作用に就いても、従来から広く知られており、本発明の要旨とも関係しない為、詳しい説明は省略する。
【００１１】
上記各堅枠４３、４３及び各方立２ａ、２ａの屋内側に連結固定した、前記支柱１ａは、図３、８に詳示する様に、支柱本体１０と、１対の竪方向化粧材１１ａ、１１ｂとから成る。このうちの支柱本体１０は、例えば厚さが２０〜３０ｍｍ程度、幅が１００〜２００ｍｍ程度の厚肉鋼板製で、上記支柱１ａの全長に亙り連続して、幅方向（断面形状の長さ方向）を屋内外方向（図３、８の上下方向）に一致させた状態で設けている。この様な支柱本体１０をその屋内側に連結固定する為に、上記方立２ａ（堅枠４３も同様、以下省略）の屋内側端部には、１対の連結板部１２、１２を設けている。これら両連結板部１２、１２は、断面クランク形で、先半部（図３、８の上半部）同士の間隔を上記支柱本体１０の厚さと同じか、この厚さよりも僅かに大きくしている。これに対して上記両連結板部１２、１２の基半部（図３、８の下半部）同士の間隔は、上記先半部の間隔よりも広くしている。上記方立２ａと支柱１ａとは、この支柱１ａと上記各連結板部１２、１２との互いに整合する複数個所に形成した通孔を挿通したボルト１３とナット１４とを螺合し更に緊締する事により、上下方向複数個所で結合固定している。
【００１２】
上述の様にして上記方立２ａの屋内側に連結固定される上記支柱１ａを覆う、上記１対の竪方向化粧材１１ａ、１１ｂは、それぞれ化粧材本体１５ａ、１５ｂと、取付ブラケット１６ａ、１６ｂとから成る。このうちの化粧材本体１５ａ、１５ｂは、木材により、断面Ｌ字形に構成して成り、表面（各取付ブラケット１６ａ、１６ｂと反対側で、屋内側に露出する面）を体裁良く仕上げている。又、上記両化粧材本体１５ａ、１５ｂの屋内側端部（図３、８の上端部）で互いに近接対向する部分は段付形状として、互いに重畳させている。そして、上記両化粧材本体１５ａ、１５ｂの不連続部を通じて、これら両化粧材本体１５ａ、１５ｂにより覆われた部分が見えない様にしている。
【００１３】
又、上記各取付ブラケット１６ａ、１６ｂは、アルミニウム合金の一体押し出し型材製で、それぞれが上記各化粧材本体１５ａ、１５ｂの裏面部分に、それぞれ複数本ずつの木ねじ１７、１７により結合固定されている。上記両取付ブラケット１６ａ、１６ｂのうち、一方（図３、８の左方）の取付ブラケット１６ａは、その両端部を上記化粧材本体１５ａの両端縁部よりも突出させている。このうちの屋外側端部は、前記方立２ａの屋内側端部に形成した１対の連結板部１２、１２のうちの一方の連結板部１２に突き合わせ、上下方向に関して複数個所を、ねじ１８により、この一方の連結板部１２に対し結合固定している。これに対して、上記一方の取付ブラケット１６ａの屋内側端部は、前記支柱本体１０の屋内側端部に溶接固定したアンカブラケット１９に突き合わせ、上下方向に関して複数個所を、ねじ２０により、このアンカブラケット１９を介して上記支柱本体１０に対し結合固定している。又、上記一方の取付ブラケット１６ａの屋内側端部には、屋内側に向け突出する係止突条２１を形成している。
【００１４】
これに対して、他方の取付ブラケット１６ｂは、その屋外側端部のみ、上記化粧材本体１５ｂの屋外側端縁から突出しており、その屋内側端部は、この化粧材本体１５ｂの屋内側端縁よりも突出してはいない。但し、上記他方の取付ブラケット１６ｂの屋内側端部には、屋外側に突出する、第二の係止突条２２を形成している。この様な他方の取付ブラケット１６ｂは、この第二の係止突条２２を上記係止突条２１に係合させる事により、この他方の取付ブラケット１６ｂの屋内側端部が上記一方の取付ブラケット１６ａから離れる方向に変位するのを防止している。そして、この状態で、その屋外側端部を、前記方立２ａの屋内側端部に形成した１対の連結板部１２、１２のうちの他方の連結板部１２に突き合わせ、上下方向に関して複数個所を、ねじ１８により、この他方の連結板部１２に対し結合固定している。
【００１５】
上述の様にして、１対の竪方向化粧材１１ａ、１１ｂを前記支柱本体１０に対し結合固定する事により、鋼製のこの支柱本体１０を隠して、前記支柱１ａの表面が木で覆われた状態とする。又、図４〜６に示す様に、前記上枠７、下枠８、及び各無目９、９の屋内側面も、木製の横方向化粧材２３ａ、２３ｂ、２３ｃにより覆って、屋内側から見た場合に、アルミニウム合金製の上記上枠７、下枠８、及び各無目９、９の屋内側面が見えない様にしている。この為に本例の場合には、これら上枠７、下枠８、及び各無目９、９の屋内側面に、開口部の幅が奥部の幅に比べて狭くなった、あり溝状の係止溝２４を形成している。又、上記各横方向化粧材２３ａ、２３ｂ、２３ｃの屋外側面の一部で、水平方向に互いに離隔した複数個所に、それぞれ板ばね製の係止片２５をねじ止め固定している。そして、これら各係止片２５を、その上下方向に関する幅寸法を弾性的に縮めつつ上記係止溝２４に押し込んでいる。この構成により上記各横方向化粧材２３ａ、２３ｂ、２３ｃを上記上枠７、下枠８、及び各無目９、９に、上記各係止片２５を介して結合し、これら上枠７、下枠８、及び各無目９、９の屋内側面を覆っている。
【００１６】
更に本例の場合には、前記方立２ａの両側面屋内寄り部分で、上記１対の竪方向化粧材１１ａ、１１ｂの屋外側端縁と前記ガラスパネル３、３の屋内側面との間部分を、第二の竪方向化粧材２６ａ、２６ｂにより覆っている。この為に本例の場合には、上記方立２ａの屋内寄り半部両側面に、開口部の幅が奥部の幅に比べて狭くなった、あり溝状の係止溝２４ａを形成している。又、上記各第二の竪方向化粧材２６ａ、２６ｂの片側面の一部で、上下方向に互いに離隔した複数個所に、それぞれ合成樹脂若しくはアルミニウム合金製の係止片２５ａをねじ止め固定している。そして、これら各係止片２５ａを、その屋内外方向に関する幅寸法を弾性的に縮めつつ上記係止溝２４ａに押し込んでいる。この構成により上記各第二の竪方向化粧材２６ａ、２６ｂを上記方立２ａの両側面屋内寄り部分に、上記各係止片２５ａを介して結合し、上記１対の竪方向化粧材１１ａ、１１ｂの屋外側端縁と上記ガラスパネル３、３の屋内側面との間部分を覆っている。尚、上記各竪方向化粧材１１ａ、１１ｂと上記各第二の竪方向化粧材２６ａ、２６ｂとの連続部も段付形状として互いに重畳させている。そして、上記各竪方向化粧材１１ａ、１１ｂ、２６ａ、２６ｂの不連続部を通じて、これら各竪方向化粧材１１ａ、１１ｂ、２６ａ、２６ｂにより覆われた部分が見えない様にしている。
【００１７】
尚、上述の様に、上記支柱本体１０を上記１対の竪方向化粧材１１ａ、１１ｂにより覆い、上記上枠７、下枠８、及び各無目９、９の屋内側面を上記各横方向化粧材２３ａ、２３ｂ、２３ｃにより覆い、更に上記方立２ａの両側面屋内寄り部分を上記１対の第二の竪方向化粧材２６ａ、２６ｂにより覆う作業は、図９〜１３に示す行程により行なう。
先ず、図９は、上記各化粧材１１ａ、１１ｂ、２３ａ、２３ｂ、２３ｃ、２６ａ、２６ｂを除き、壁構造体を構築した状態を示す。即ち、本例の壁構造体を構築する場合、上記支柱１ａと前記方立２ａと前記上枠７と前記下枠８と前記無目９、９とを結合組み合わせると共に、これら方立２ａと上枠７と下枠８と無目９、９との間に前記ガラスパネル３、３を建て込む。そして、上記各化粧材１１ａ、１１ｂ、２３ａ、２３ｂ、２３ｃ、２６ａ、２６ｂを後から装着する。
【００１８】
これら各化粧材１１ａ、１１ｂ、２３ａ、２３ｂ、２３ｃ、２６ａ、２６ｂの装着作業を行なう場合、先ず、図１０に示す様に、上記方立２ａと上枠７と下枠８と無目９、９との屋内側面に、上記各横方向化粧材２３ａ、２３ｂ、２３ｃを、前述した様に、係止溝２４と係止片２５との係合により装着する。
次いで、図１１〜１２に示す様に、上記支柱本体１０に上記各竪方向化粧材１１ａ、１１ｂの組み付け作業を、前記一方の取付ブラケット１６ａを組み付けた竪方向化粧材１１ａの組み付け作業を先に、前記他方の取付ブラケット１６ｂを組み付けた竪方向化粧材１１ｂの組み付け作業を後からの順番で行なう。
そして最後に、図１３に示す様に、第二の竪方向化粧材２６ａ、２６ｂを、上記方立２ａの両側面屋内寄り部分に、前述した様に、係止溝２４ａと係止片２５ａとの係合により装着する。
【００１９】
次に、前記支柱本体１０の上下両端部を前記天井面５或は前記床面６に結合固定する部分の構造に就いて、図３〜５図及び図７を参照しつつ説明する。
上記支柱本体１０の上下両端部はそれぞれ、図７にその全体を示す様な１対の固定ブラケット２７、２７を介して、上記天井面５（図４）及び上記床面６（図５）に対し結合固定している。上記各固定ブラケット２７、２７はそれぞれ、水平板部２８と鉛直板部２９とを備えたＬ字形で、このうちの水平板部２８の中央部に第一の通孔３０を、鉛直板部２９の中央部で水平方向に離隔した２個所位置に第二の通孔３１、３１を、それぞれ形成している。
【００２０】
又、上記鉛直板部２９の両側面のうちの上記水平板部２８と反対側の面で、上記支柱本体１０の側面に対向する側面に、上記鉛直板部２９毎に１対ずつの環状スペーサ３２、３２を溶接等により固定している。これら各環状スペーサ３２、３２の外径Ｄ_３２は、上記各第二の通孔３１、３１の内径Ｒ_３１よりも大きく、その内径ｒ_３２はこれら各第二の通孔３１、３１の内径Ｒ_３１よりも小さく（Ｄ_３２＞Ｒ_３１＞ｒ_３２）、その厚さｔ_３２は上記支柱本体１０の厚さＴ_１０の１／２以下（ｔ_３２≦Ｔ_１０／２）である。この様な上記各環状スペーサ３２、３２はそれぞれ、上記各第二の通孔３１、３１と同心に配置した状態で、上記鉛直板部２９の片側面に、溶接、接着等により固定している。
【００２１】
これに対して、上記支柱本体１０の上下両端部には、それぞれが上下方向に長い長孔３３、３３を、これら両端部毎に１対ずつ形成している。これら各長孔３３、３３の幅Ｗ_３３は、上記各環状スペーサ３２、３２の外径Ｄ_３２よりも少しだけ大きく（Ｗ_３３＞Ｄ_３２）している。又、上記各長孔３３、３３のピッチＰ_３３と、上記各環状スペーサ３２、３２のピッチＰ_３２とは、互いに同じ（Ｐ_３３＝Ｐ_３２）としている。従って、上記各固定ブラケット２７、２７の鉛直板部２９を上記支柱本体１０の上下両端部両側面に当接させた状態では、上記各環状スペーサ３２、３２が、上記各長孔３３、３３内に進入する。この状態で、これら各長孔３３、３３の両端開口部から入り込んだ上記各環状スペーサ３２、３２の先端面は、丁度当接する（ｔ_３２＝Ｔ_１０／２の場合）か、又は、図３に示す様に、互いの間に隙間が介在する状態となる（ｔ_３２＜Ｔ_１０／２の場合）。
【００２２】
それぞれが前述の様に環状スペーサ３２、３２を備えた１対ずつの固定ブラケット２７、２７により、上述の様に１対ずつの長孔３３、３３を形成した上記支柱本体１０の上下両端部を前記天井面５又は前記床面６に支持固定する作業は、次の様にして行なう。尚、これら天井面５及び床面６の一部で、上記支柱本体１０の上下各端部を支持固定すべき部分には、図４〜５に示す様に、それぞれアンカプレート３４ａ、３４ｂとスタッド３５ａ、３５ｂとを、コンクリートの打設時に埋設しておく。又、これらアンカプレート３４ａ、３４ｂは上記天井面５又は床面６に露出しており、上記各スタッド３５ａ、３５ｂの先端部は、上記各アンカプレート３４ａ、３４ｂから突出している。又、これら各スタッド３５ａ、３５ｂの外径は、前記水平板部２８に形成した第一の通孔３０の内径よりも十分に小さい。この理由は、上記天井面５及び床面６に対する、上記支柱本体１０の上下両端部の支持固定位置の調節を可能にする為である。
【００２３】
上記各固定ブラケット２７、２７は、上記各スタッド３５ａ、３５ｂを上記第一の通孔３０に挿通し、これら各スタッド３５ａ、３５ｂに外嵌したワッシャ３６及び同じく螺合したナット３７と上記各アンカプレート３４ａ、３４ｂとの間で上記水平板部２８を挟持する事により、上記天井面５及び床面６に装着する。この様にして、上記各アンカプレート３４ａ、３４ｂ毎に１対ずつ装着した上記各固定ブラケット２７、２７の鉛直板部２９、２９により、上記支柱本体１０の上端部及び下端部を挟持する。この際、上記各環状スペーサ３２、３２を上記各長孔３３、３３内に、両端開口から進入させる。そして、これら各環状スペーサ３２、３２を挿通したボルト３８、３８とナット３９、３９とを螺合し更に緊締する事により、上記支柱本体１０の上端部及び下端部をそれぞれ１対ずつの固定ブラケット２７、２７に対し固定する。
【００２４】
この様にして、上記支柱本体１０の上下両端部を、それぞれ１対ずつの固定ブラケット２７、２７により、上記天井面５又は床面６に対し結合固定する。この場合に、これら天井面５又は床面６に対する上記支柱本体１０の上下両端部の取付位置は、水平方向に関しては、上記第一の通孔３０内で上記各スタッド３５ａ、３５ｂが変位できる範囲内で調節できる。又、鉛直方向に関しては、上記各環状スペーサ３２、３２が上記各長孔３３、３３内で動き得る範囲内で、それぞれ調節できる。そこで、上記各ナット３７、３９を緊締する以前に、上記各方向の位置調節を行なってから、これら各ナット３７、３９を緊締する。その後、上記各固定ブラケット２７、２７の水平板部２８、２８と上記各アンカプレート３４ａ、３４ｂを溶接すると共に、上記支柱本体１０の上端部と上記鉛直板部２９とを溶接する。この支柱本体１０の下端部と鉛直板部２９とは溶接しない。溶接しない理由は、この支柱本体１９の下端部を若干の変位可能にし、気温変化による膨張収縮等により、上記支柱本体１０に過大な応力が加わる事を防止する為である。
【００２５】
上記支柱本体１０の上下両端部は、上述の様にして、上記天井面５又は床面６に対し結合固定するが、この結合固定に使用する、前記ボルト３８の頭部４０及び上記ナット３９の外径は、前記第二の通孔３１の内径Ｒ_３１よりも小さい。又、上記ボルト３８の全長は、上記支柱本体１０の厚さＴ_１０と上記１対の鉛直板部２９、２９の厚さｔ_２９との合計（Ｔ_１０＋２ｔ_２９）とほぼ同じとしている。従って、ボルト３８とナット３９とを螺合し更に緊締した状態では、これらボルト３８及びナット３９は、上記各鉛直板部２９、２９の側面から殆ど突出しない。又、上記１対の鉛直板部２９、２９の厚さｔ_２９はあまり大きくない。
【００２６】
従って、上記支柱本体１０の上下両端部を上記各固定ブラケット２７、２７を介して上記天井面５又は床面６に対し結合固定した後、上記支柱本体１０を前記各竪方向化粧材１１ａ、１１ｂにより覆えば、上記各固定ブラケット２７、２７の鉛直板部２９、２９は、図３に示す様に、上記支柱本体１０の上下両端部の両側面と、上記各竪方向化粧材１１ａ、１１ｂを構成する取付ブラケット１６ａ、１６ｂの上下両端部内面との間に入り込んだ状態となる。従って、上記各鉛直板部２９、２９が、外部に露出する事がなくなる。この為、前記支柱１ａの上下両端部の体裁を整える為の工事は、上記各固定ブラケット２７、２７の水平板部２８、２８を隠すだけの程度で済む。これら各水平板部２８、２８の厚さ寸法は限られており、これを隠す作業は、竪方向寸法が大きい上記鉛直板部２９、２９を隠す作業に比べて容易である。
【００２７】
前述の様に構成し、上述の様に構築する本例の壁構造体４の場合には、構成各部材の重量を支える支柱本体１０が鋼製である為、この支柱本体１０の断面積をあまり大きくする事なく、十分な強度を確保できる。この為、前記各竪方向化粧材１１ａ、１１ｂを含んだ状態でも、上記支柱１ａの厚さ寸法Ｔ_１ａを小さくできて、その分前記ガラスパネル３、３の面積を広くし易くなる等、好ましい意匠を実現する事に関する自由度が向上する。又、鋼製に比べて高価な、木製の上記各竪方向化粧材１１ａ、１１ｂの容積を少なくできて、コスト低減を図れる。又、これら各竪方向化粧材１１ａ、１１ｂは上記壁構造体４の構成各部材の重量を支える強度部材でない為、損傷した場合に、他の部材を取り除く事なく、上記各竪方向化粧材１１ａ、１１ｂのみを着脱する事ができる。この為、修理、交換に要するコストの低減も図れる。
【００２８】
次に、図１４は、本発明の実施の形態の第２例を示している。本例の場合には、１対の竪方向化粧材１１ｃ、１１ｄを構成する化粧材本体１５ｃ、１５ｃを互いに同じ形状としている。そして、これら両化粧材本体１５ｃ、１５ｃの屋内側端縁同士の突き合わせ部同士の間にスペーサ４１を、上記両竪方向化粧材１１ｃ、１１ｄの全長に亙って挟持している。このスペーサ４１は、アルミニウム合金或は合成樹脂の一体押し出し成形材、又はステンレス鋼、銅系合金製で、その上下方向複数個所を一方の竪方向化粧材１１ｃを構成する取付ブラケット１６ａに対し、ねじ４２により結合支持している。その他の部分の構成及び作用は、上述した第１例の場合と同様である為、同等部分に関する図示並びに説明は省略する。
尚、本発明を実施する場合に、各化粧材の表面を構成する材料は、木に限らず、合成樹脂等、他の非金属材料とする事もできる。又、全高が低い構造の場合には、支柱本体を鉄又は鉄系合金に限らず、アルミニウム合金製（中空又は充実体）とする事もできる。
【００２９】
【発明の効果】
本発明は、以上に述べた通り構成し作用する為、意匠上の設計の自由度が高く、しかも建設時のコスト並びに修理に要するコストを低く抑えられる壁構造体を実現できる。

In particular, the wall structure of the present invention covers the indoor space by covering the portion exposed to the indoor space with a non-metallic material, such as wood, in a cubicle supporting the four sides of the glass panel for daylighting or blind. It is related to the improvement of the structure so as not to give a person the inorganic feeling.
[0002]
[Prior art]
It separates the indoor space such as the lobby and hall of various buildings from the outdoor space, and it is a lighting wall that takes in external light into this indoor space. A structure that does not give an unpleasant feeling is described in Patent Document 1 and is conventionally known. In the structure described in this patent document 1, as shown in FIG. 15, a cubicle 2 is fixedly connected to the outdoor side surface of a wooden column 1, and the cubicle 2 or a vertical frame (not shown) The upper and lower frames support the four sides of the plurality of glass panels 3.

[0004]
[Problems to be solved by the invention]
In the case of the conventional structure described in Patent Literature 1 as described above, the wooden column 1 is a strength member, and the column 1 is used to form a plurality of glass panels 3, 3 in addition to the cubic 2 and the blind. Supports weight. On the other hand, wood has lower mechanical strength such as Young's modulus than metal materials such as steel. For this reason, when configuring a large wall structure, the cross-sectional area of the column 1 needs to be considerably widened. Increasing the cross-sectional area of the support column 1 leads to a reduction in the area and floor area of each of the glass panels 3 and 3, and makes it easier for the person in the indoor space to feel heavy. It is often unfavorable.
[0005]
In addition, if the strut 1 having a design-appropriate appearance and having sufficient strength is made of only wood, even if it is a laminated wood using thinned wood, it is inevitable that the cost is considerably increased. . Moreover, the wood is easily damaged, and when used for a long period of time, there is a high possibility that the surface may be damaged due to the collision of some hard objects. In such a case, if the entire support 1 as a strength member is made of wood, it is very difficult to replace only the damaged support 1. Even if only the damaged strut 1 can be replaced, the cost required for replacement becomes extremely high. Therefore, surface flaws must be repaired in the field, increasing costs.
In view of such circumstances, the present invention can reduce the construction cost itself, and can also reduce the cost required for repair and replacement when the surface is damaged, and furthermore, a wall structure that can easily realize a preferable design. It was invented to provide a body.
[0006]
[Means for Solving the Problems]
The wall structure of the present invention, similarly to a conventionally known wall structure, combines a plurality of cubicles and eyelets in directions intersecting each other, and a plurality of In addition to supporting the panels, a plurality of columns are provided on the indoor side of each of the cubicles to support these cubicles, the blinds, and the panels.
In particular, in the wall structure of the present invention, these pillars are fixedly connected to the respective indoor sides of the respective cubicles, and the upper and lower ends are respectively fixed to the fixed portions. , Each of which has at least a surface made of a non-metallic material, and is composed of a plurality of decorative materials that cover the support body in a combined state.
[0007]
[Action]
In the case of the wall structure of the present invention configured as described above, since the column main body that supports the weight of each constituent member is made of metal, sufficient strength can be obtained without increasing the cross-sectional area of the column main body too much. Can be secured. For this reason, even in a state where the decorative material is included, the width of the column can be reduced, and the area of the panel can be easily increased.
[0008]
In addition, the cosmetic material only needs to cover the above-mentioned metal pillar main body, so that the thickness dimension may be small. Therefore, even when the decorative material is made of wood, the cost of the decorative material can be reduced. Furthermore, even if the decorative material is removed from the main body of the support, the support of the panel is not affected at all, so that only the damaged decorative material can be easily repaired or replaced. Therefore, the cost required for the repair and replacement can be kept low.
[0009]

[0019]
Next, the structure of a portion for connecting and fixing the upper and lower ends of the column body 10 to the ceiling surface 5 or the floor surface 6 will be described with reference to FIGS.
The upper and lower ends of the column body 10 are respectively connected to the ceiling surface 5 (FIG. 4) and the floor surface 6 (FIG. 5) via a pair of fixing brackets 27, 27 as shown in FIG. On the other hand, it is fixed. Each of the fixing brackets 27 has an L-shape including a horizontal plate portion 28 and a vertical plate portion 29, and a first through hole 30 is provided at the center of the horizontal plate portion 28, and the vertical plate portion 29 is provided at the center of the horizontal plate portion 28. The second through-holes 31, 31 are formed at two positions horizontally separated from each other at the center of the first through hole.
[0020]
A pair of annular spacers is provided for each of the vertical plate portions 29 on a side surface of the opposite side surface of the vertical plate portion 29 opposite to the horizontal plate portion 28 and on a side surface facing the side surface of the support column body 10. 32, 32 are fixed by welding or the like. The outer diameter D of each of these annular spacers 32, 32 ₃₂ Is the inner diameter R of each of the second through holes 31, 31 ₃₁ Larger than its inner diameter r ₃₂ Is the inner diameter R of each of these second through holes 31, 31 ₃₁ Smaller than (D ₃₂ > R ₃₁ > R ₃₂ ), Its thickness t ₃₂ Is the thickness T of the support body 10 ₁₀ 1/2 or less (t ₃₂ ≤T ₁₀ / 2). Such annular spacers 32, 32 are fixed to one side surface of the vertical plate portion 29 by welding, bonding, or the like, respectively, in a state of being arranged concentrically with the second through holes 31, 31, respectively. .
[0021]
On the other hand, the upper and lower ends of the column main body 10 are formed with a pair of elongated holes 33, 33, which are long in the vertical direction, respectively. The width W of each of the long holes 33, 33 ₃₃ Is the outer diameter D of each of the annular spacers 32, 32. ₃₂ Slightly larger than (W ₃₃ > D ₃₂ )are doing. Also, the pitch P of each of the long holes 33, 33 ₃₃ And the pitch P of the annular spacers 32, 32 ₃₂ Are the same as each other (P ₃₃ = P ₃₂ ). Therefore, in a state where the vertical plate portions 29 of the fixing brackets 27 abut on both side surfaces of the upper and lower ends of the support body 10, the annular spacers 32 are formed in the elongated holes 33, 33. To enter. In this state, the leading end surfaces of the annular spacers 32, 32 that have entered through the openings at both ends of the elongated holes 33, 33 just contact (t). ₃₂ = T ₁₀ / 2) or, as shown in FIG. 3, a state in which a gap is interposed between each other (t) ₃₂ <T ₁₀ / 2).
[0022]
The pair of fixing brackets 27, 27 each having the annular spacers 32, 32 as described above, the upper and lower ends of the column main body 10 in which the pairs of slots 33, 33 are formed as described above. The work of supporting and fixing to the ceiling surface 5 or the floor surface 6 is performed as follows. As shown in FIGS. 4 and 5, anchor portions 34a and 34b and studs are respectively provided on portions of the ceiling surface 5 and the floor surface 6 where the upper and lower ends of the column body 10 are to be supported and fixed. 35a and 35b are buried when concrete is poured. The anchor plates 34a and 34b are exposed on the ceiling surface 5 or the floor surface 6, and the tips of the studs 35a and 35b protrude from the anchor plates 34a and 34b. The outer diameter of each of the studs 35a and 35b is sufficiently smaller than the inner diameter of the first through hole 30 formed in the horizontal plate portion 28. The reason for this is to enable adjustment of the supporting and fixing positions of the upper and lower ends of the column body 10 with respect to the ceiling surface 5 and the floor surface 6.
[0023]
Each of the fixing brackets 27, 27 inserts each of the studs 35a, 35b into the first through hole 30, and the washer 36 and the nut 37 screwed to the studs 35a, 35b are screwed to the respective anchors. By mounting the horizontal plate portion 28 between the plates 34a and 34b, the horizontal plate portion 28 is mounted on the ceiling surface 5 and the floor surface 6. In this manner, the upper and lower ends of the support column main body 10 are sandwiched by the vertical plate portions 29, 29 of the fixing brackets 27, 27, one pair of which is mounted on each of the anchor plates 34a, 34b. At this time, the annular spacers 32 are made to enter the elongated holes 33 from the openings at both ends. Then, the bolts 38, 38, into which the annular spacers 32, 32 are inserted, and the nuts 39, 39 are screwed together and further tightened, so that the upper end portion and the lower end portion of the support body 10 are fixed in pairs. 27, 27 fixed.
[0024]
In this way, the upper and lower ends of the column main body 10 are connected and fixed to the ceiling surface 5 or the floor surface 6 by a pair of fixing brackets 27, 27, respectively. In this case, the mounting positions of the upper and lower ends of the column main body 10 with respect to the ceiling surface 5 or the floor surface 6 are such that the studs 35a and 35b can be displaced within the first through hole 30 in the horizontal direction. Can be adjusted within. Further, in the vertical direction, each of the annular spacers 32, 32 can be adjusted within a range in which it can move within each of the elongated holes 33, 33. Therefore, before tightening the nuts 37 and 39, the position is adjusted in each direction, and then the nuts 37 and 39 are tightened. Thereafter, the horizontal plates 28, 28 of the fixed brackets 27, 27 are welded to the anchor plates 34a, 34b, and the upper end of the support body 10 and the vertical plate 29 are welded. The lower end of the support body 10 and the vertical plate portion 29 are not welded. The reason why welding is not performed is to make it possible to slightly displace the lower end portion of the column main body 19 and prevent excessive stress from being applied to the column main body 10 due to expansion and contraction due to a temperature change.
[0025]
The upper and lower ends of the column body 10 are fixedly connected to the ceiling surface 5 or the floor surface 6 as described above. The head 40 of the bolt 38 and the nut 39 used for this connection and fixing are fixed. The outer diameter is the inner diameter R of the second through hole 31. ₃₁ Less than. The total length of the bolt 38 is equal to the thickness T of the support body 10. ₁₀ And the thickness t of the pair of vertical plate portions 29, 29 ₂₉ (T ₁₀ + 2t ₂₉ ) And almost the same. Therefore, when the bolt 38 and the nut 39 are screwed together and tightened further, the bolt 38 and the nut 39 hardly protrude from the side surfaces of the vertical plate portions 29, 29. The thickness t of the pair of vertical plate portions 29, 29 ₂₉ Is not so big.
[0026]
Therefore, after the upper and lower ends of the support body 10 are connected and fixed to the ceiling surface 5 or the floor surface 6 via the fixing brackets 27, 27, the support body 10 is connected to the vertical decorative materials 11a, 11b. As shown in FIG. 3, the vertical plate portions 29, 29 of the fixing brackets 27, 27, as shown in FIG. The mounting brackets 16a, 16b are inserted between the upper and lower inner surfaces. Therefore, the vertical plate portions 29 are not exposed to the outside. For this reason, the work for adjusting the appearance of the upper and lower ends of the column 1a is only required to cover the horizontal plate portions 28, 28 of the fixing brackets 27, 27. The thickness of each of the horizontal plate portions 28 is limited, and the work of hiding the horizontal plate portions 28, 28 is easier than the work of hiding the vertical plate portions 29, 29 having a large vertical dimension.
[0027]
In the case of the wall structure 4 of the present embodiment constructed as described above and constructed as described above, since the column main body 10 supporting the weight of each component is made of steel, the cross-sectional area of the column main body 10 is reduced. Sufficient strength can be secured without making it too large. For this reason, even when the vertical dressing materials 11a and 11b are included, the thickness T _1a And the degree of freedom relating to realizing a preferable design is improved, for example, the area of the glass panels 3 is easily increased. Further, the volume of each of the wooden vertical decorative materials 11a and 11b, which is more expensive than steel, can be reduced, and the cost can be reduced. Further, since each of the vertical decorative materials 11a and 11b is not a strength member that supports the weight of each component of the wall structure 4, if it is damaged, each of the vertical decorative materials 11a and 11b can be removed without removing other members. , 11b alone. Therefore, the cost required for repair and replacement can be reduced.
[0028]
Next, FIG. 14 shows a second example of the embodiment of the present invention. In the case of this example, the decorative material main bodies 15c, 15c constituting the pair of vertical decorative materials 11c, 11d have the same shape. A spacer 41 is sandwiched between the butted portions of the indoor side edges of both the decorative material main bodies 15c, 15c over the entire length of the vertical decorative materials 11c, 11d. The spacer 41 is made of an integrally extruded material of an aluminum alloy or a synthetic resin, or is made of stainless steel or a copper-based alloy. 42 are connected and supported. Since the configuration and operation of the other parts are the same as those in the first example, illustration and description of the equivalent parts are omitted.
In practicing the present invention, the material constituting the surface of each decorative material is not limited to wood, but may be other non-metallic materials such as synthetic resin. In the case of a structure having a low overall height, the column body is not limited to iron or an iron-based alloy, and may be made of an aluminum alloy (hollow or solid body).
[0029]
【The invention's effect】
Since the present invention is configured and operates as described above, it is possible to realize a wall structure that has a high degree of design freedom in design, and that can reduce costs during construction and costs required for repair.
