Description

【０００１】
【発明の属する技術分野】
本発明は、縦枠や方立等の縦材と、上枠や下枠や無目等の横材とに囲まれる部分にガラス板や化粧パネル板等のパネル板材を組み込んでなり、建築物の２階以上のカーテンウォールや１階部分のフロント等をなす外壁構造に関し、特に、防水構造の改良に関する技術分野に属する。
【０００２】
【従来の技術】
従来より、建築物の２階以上の外壁部を構成するカーテンウォールは、垂直上下方向に延びる縦材としての複数の方立間に、水平左右方向に延びる横材としての無目を先端部が方立の側面に突き合わされるように略格子状に交差させ、これら方立及び無目に囲まれる枠内にガラス板や化粧パネル等のパネル板材を組み込んで建築物の外壁部を形成するものとして知られており、上記方立及び無目としては、建築物の外壁部で風雨に晒されるために、発錆が生じ難いアルミニウム製のものが一般に用いられている。
【０００３】
しかし、このアルミニウム等の金属は熱良導体であるので、冬季で外気により方立や無目が冷却されると、その方立や無目の室内に露出している部分に結露が発生したり、伝熱により暖房効果が低下したりする等の欠点がある。
【０００４】
そこで、このような金属製の方立及び無目の持つ欠点を解決するために、従来、例えば特許文献１に示されるように、方立として木製材料を用いた木製方立とし、その室外側となる外面にアルミニウム等の金属製下地材を固定し、この金属製下地材に方立の長さ方向に延びるスリットや長孔を形成して、このスリット等に金属製取付具をスライド移動可能に挿入し、この取付具に内押縁部材を連結して、該内押縁部材と外押縁部材との間にパネル材の縦縁部を挟み込むことにより、パネル材側の金属製取付具と木製方立との熱膨張差を、金属製下地材のスリット等での取付具の相対移動により吸収するようにしたものが提案されている。
【０００５】
ところで、上記方立の如き縦材や、無目の如き横材を施工する場合、それらを長さ方向と直角に切断したままで、縦材側面に横材の端部を突き合わせてビス等により結合して組立施工することが行われる。しかし、縦材の側面にはガラス板や化粧パネル等のパネル板材の左右方向の縁部を収容するための縦凹溝が形成されており、この縦材側面に横材の端部を突き合わせるだけでは、縦凹溝が横材を越えて上下に貫通したままとなるので、雨漏りを防ぐことはできない。
【０００６】
そこで、従来、縦凹溝内にシーリング受け、溝塞ぎピース、マットシーラ押えと呼ばれる溝塞ぎ部材を充填してその上面をシーリング材によりシールすることにより、縦凹溝を横材の位置で塞ぐことが行われている（例えば非特許文献１〜３参照）。

【発明が解決しようとする課題】
ところが、上記従来の非特許文献１〜３のように、凹溝内に溝塞ぎ部材を充填してその上面をシールする構造では、例えば、予め横材の製造工程で凹溝内に溝塞ぎ部材を取り付けておくようにしたとしても、その取付忘れが生じたり、或いは施工現場への運搬中に溝塞ぎ部材が外れたりすることは避けられず、防水対策を安定して確実に行うのが難しいという問題があった。
【０００９】
本発明は斯かる点に鑑みてなされたもので、その目的は、横材の構造に改良を加えることにより、施工時に縦材に横材を組み付けると同時に自動的に縦凹溝途中の閉塞を行い得るようにして、防水対策を安定して確実に行うことにある。
【００１０】
【課題を解決するための手段】
上記の目的を達成するために、この発明では、横材においてガラス板等のパネル板材の上下方向の縁部を収容するための横凹溝に着目し、この横凹溝の底部分を他の部分よりも延ばして、その先端部を縦材の縦凹溝内に嵌合するようにした。
【００１１】
具体的には、請求項１の発明では、垂直上下方向に延びる縦材と、先端部が上記縦材の側面に突き合わされて配置され、水平左右方向に延びる横材とにより囲まれる部分にパネル板材を嵌め込んだ建築物の外壁構造が前提である。
【００１２】
そして、上記縦材には上記パネル板材の左右方向の縁部を収容するための縦凹溝が、また横材にはパネル板材の上下方向の縁部を収容するための横凹溝がそれぞれ形成されており、少なくとも上記パネル板材下側に位置する横材は、縦材間の間隔と略同じ長さを有する横材本体と、この横材本体に別体に設けられていて長さ方向にスライド可能に係止され、上記横凹溝の少なくとも底部に位置する防水スライド部とを備えてなり、上記防水スライド部は横材本体の長さ方向の端部から突出していて、その防水スライド部の突出端部は上記縦凹溝内に液密シール状態で嵌合されている構造とする。
【００１３】
上記の構成によると、建築物の外壁部を組み立てるとき、縦材の側面に横材の先端部を突き当てて両者を結合し、縦材の縦凹溝にパネル板材の左右方向の縁部を、また横材の横凹溝にパネル板材の上下方向の縁部をそれぞれ嵌装することで、その各凹溝内にパネル板材の各縁部が収容される。
【００１４】
そして、少なくともパネル板材下側に位置する上記横材には、横材本体とは別体で横凹溝の少なくとも底部に位置する防水スライド部が横材本体にスライド可能に係合され、この防水スライド部は横材本体の長さ方向の端部から突出しているので、上記のように、縦材の側面に横材の先端部を突き当てて両者を結合したときに、その横材本体は縦材の側面に当接するが、防水スライド部の突出端部は縦材の縦凹溝内に入り込む。そして、この防水スライド部の突出端部と縦凹溝内との間にシール材等を介在させることで、防水スライド部の突出端部が縦凹溝内に液密シール状態で嵌合される。従って、施工時に縦材に横材を組み付けると同時に、横材の防水スライド部の突出端部で縦材の縦凹溝の途中を閉塞でき、従来のような溝塞ぎ部材の取付忘れや外れが生じる余地はなく、防水対策を安定して確実に行うことができる。
【００１５】
また、横材の防水スライド部が横材本体から突出しているので、両者が一体の場合には横材を横材本体と防水スライド部とで異なる長さに切り欠く必要があるが、上記防水スライド部は横材本体と別体に設けられていて、その横材本体にスライド可能に係止されているので、予め、防水スライド部を所定長さに切断した後に横材本体に係止して取り付ければよく、施工を容易に行うことができる。
【００１６】
請求項２の発明では、上記縦材及び横材はそれぞれ室内側部材と室外側部材とに分割され、上記室内側部材は、金属製の心材と木質材料又は樹脂材料からなる外装材とを、心材の室外部が部分的に外装材から室外側に露出するように接合一体化してなり、その外装材から室外側に露出した心材と室外側部材とにより凹溝が設けられている構造とする。
【００１７】
このことで、室内側部材が金属製心材と外装材とを心材の室外部が部分的に外装材から室外側に露出するように接合一体化してなるので、心材の室内側が外装材によって覆われた構造となり、室内外に温度差があっても、室内外間で伝熱され難く、金属材と木材や樹脂材との温度差による熱膨張を考慮せずとも済み、構造を簡単にすることができる。
【００１８】
しかも、上記室内側部材が心材と外装材との複合材であるので、これら心材により室内側部材の強度を確保することができ、その室内側部材を木製材料のみや樹脂材料のみで形成した場合に比べ、室内側部材の全体の断面積を小さくして、太さの細いものを使用することができる。
【００１９】
請求項３の発明では、建築物の外壁構造はフロント、カーテンウォール又はサッシに用いられているものとする。こうすると、本発明の効果が有効に発揮される最適な建築物の外壁構造が得られる。
【００２０】
【発明の実施の形態】
（実施形態１）
図１は本発明の実施形態１に係る建築物の１階部分の外壁部Ａ（フロント）を示し、この外壁部Ａは、垂直上下方向に延びる縦材としての左右１対の縦枠１，１と、両縦枠１，１の上端部間に架設されて水平左右方向に延びる上枠２と、両縦枠１，１の下端部間に架設されて水平左右方向に延びる下枠３とを備え、上枠２及び下枠３の先端部を縦枠１，１の側面に突き合わせて配置することにより、矩形枠状に形成されている。そして、これら縦枠１，１、上枠２及び下枠３に囲まれる部分にパネル板材としてのガラス板６が嵌め込まれている。このガラス板６は、図２及び図３に示すように、２枚の板ガラス６ａ，６ａを空気層をあけて重ねかつ両板ガラス６ａ，６ａ間の周縁部に封着材６ｂを介在させて該封着材６ｂで空気層を封入した複層ガラスからなる。尚、この複層ガラスの他、１枚ガラスを用いてもよいのは勿論である。
【００２１】
図３に拡大して示すように、上記左側縦枠１の右側面には上記ガラス板６の左縁部を収容する右側に開口する縦凹溝８が、また右側縦枠２の左側面にはガラス板６の右縁部を収容する左側に開口する同様の縦凹溝８がそれぞれ形成されている。
【００２２】
上記各縦枠１はそれぞれ室内側（図３で上側）に位置する室内側部材１１と、室外側（同下側）に位置する室外側部材１６とに分割されている。この室内側部材１１は、アルミニウム製押出材からなる心材１２と木質材料（又は樹脂材料であってもよい）からなる外装材１３とを、心材１２の室外部が部分的に外装材１３から室外側に露出するように接合一体化してなる。具体的には、心材１２は、対向する縦枠１と反対側に開口された断面略コ字状の本体部１２ａと、この本体部１２ａの室外側面に突設された板部１２ｂと、この板部１２ｂの先端部から対向する縦枠１と反対側に向かって左右方向に延びる板状の取付部１２ｃとからなり、この取付部１２ｃの先端部は室内側に折れ曲がっている。そして、上記本体部１２ａにその相対する縦枠１側の側面ないし室内側側面に亘りそれら側面を覆うように上記外装材１３が接着やビス止め等の手段により一体的に取り付けられており、この外装材１３の室外側面と心材１２の本体部１２ａの室外側面とは面一となっている。尚、１２ｄは心材１２の本体部１２ａにおいて相対する縦枠１側の側部に形成された突条で、外装材１３との接合時にその外装材１３に形成した凹条１３ａに嵌合される。
【００２３】
一方、縦枠１の上記室外側部材１６は、上下方向に延びる目板カバー受け１７及び目板カバー１８からなる。上記目板カバー受け１７は、上記心材１２の本体部１２ａの左右幅と略同じ左右幅を有するもので、心材１２の取付部１２ｃ外面に断熱パッキン１９を介して取付ビス２０により取り付けられている。上記断熱パッキン１９は温度差による心材１２と目板カバー受け１７等との間の伸びの差を抑制するために用いられる。目板カバー受け１７の左右端部には室外側に突出する１対の係合突起１７ａ，１７ａが一体に形成されている。
【００２４】
また、目板カバー１８は室内側に開放された断面略コ字状のもので、室内側に突出する１対の係合部１８ａ，１８ａを有しており、これらの係合部１８ａ，１８ａをそれぞれ目板カバー受け１７の係合突起１７ａ，１７ａに外嵌合状態で係合させることで、目板カバー１８が目板カバー受け１７に上記取付ビス２０を隠すように取り付けられる。そして、上記外装材１３から室外側に露出した心材１２、つまり本体部１２ａの一部及び板部１２ｂと、室外側部材１６の目板カバー受け１７とにより上記縦凹溝８が設けられており、この縦凹溝８にガラス板６の左縁部又は右縁部が収容される。
【００２５】
これに対し、図２に示すように、上枠２の下面にはガラス板６の上縁部を収容する下側に開口する横凹溝９が、また下枠３の上面にはガラス板６の下縁部を収容する上側に開口する同様の横凹溝９がそれぞれ形成されている。
【００２６】
上記上枠２も、室内側（図２で右側）に位置する室内側部材２３と、室外側（同左側）に位置する室外側部材２８とに分割されている。この上枠２の室内側部材２３は、上記縦枠１と同様に、アルミニウム製押出材からなる心材２４と木質材料（樹脂材料でもよい）からなる外装材２５とを、心材２４の室外部が部分的に外装材２５から室外側に露出するように接合一体化してなる。すなわち、心材２４は、上側に開口された断面略コ字状の本体部２４ａと、この本体部２４の室外側面に突設された板部２４ｂと、この板部２４ｂの先端部から下側に向かって延びる板状の取付部２４ｃとからなる。そして、本体部２４ａにはその下面ないし室内側側面に亘りそれらを覆うように上記外装材２５が接着やビス止め等により一体的に取り付けられており、この外装材１５の室外側面と心材２４の本体部２４ａの室外側面とは面一となっている。２４ｄは心材２４の本体部２４ａにおける下部に形成された突条で、外装材２５との接合時にその外装材２５に形成した凹条２５ａに嵌合される。
【００２７】
一方、上枠２の室外側部材２８は、水平左右方向に延びる目板カバー受け２９及び目板カバー３０からなり、目板カバー受け２９は、上記室内側部材２３（心材２４の本体部２４ａ及び外装材２５）の上下幅と略同じ上下幅を有するもので、上記心材２４の取付部２４ｃ外面に断熱パッキン３１を介して取付ビス３２により取り付けられている。目板カバー受け２９の上下端部には室外側に突出する１対の係合突起２９ａ，２９ａが一体に形成されている。
【００２８】
また、目板カバー３０は室内側に開放された断面略コ字状のもので、室内側に突出する１対の係合部３０ａ，３０ａを有しており、これら係合部３０ａ，３０ａをそれぞれ目板カバー受け２９の係合突起２９ａ，２９ａに外嵌合状態で係合させることで、目板カバー３０が目板カバー受け２９に取付ビス３２を隠すように取り付けられる。そして、上記外装材２５から室外側に露出した心材２４、つまり本体部２４ａの一部及び板部２４ｂと、室外側部材２８の目板カバー受け２９とにより上記横凹溝９が設けられており、この横凹溝９にガラス板６の上縁部が収容される。
【００２９】
上記下枠３も、室内側に位置する室内側部材３５と室外側に位置する室外側部材４２とに分割されている。この下枠３の室内側部材３５は、アルミニウム製押出材からなる心材３６と木質材料（樹脂材料であってもよい）からなる外装材３９とを、心材３６の室外部が部分的に外装材３９から室外側に露出するように接合一体化してなる。すなわち、心材３６は、下側に開口された断面略コ字状の本体部３７と、防水スライド板３８（防水スライド部）とを備え、この防水スライド板３８は心材３６の一部をなしている。上記本体部３７には上面ないし室内側側面に亘りそれらを覆うように上記外装材３９が接着やビス止め等により一体的に取り付けられており、この外装材３９の室外側面と心材３６の本体部３７の室外側面とは面一となっている。尚、３７ａは心材３６の本体部３７における室内側部に形成された突条で、外装材３９との接合時にその外装材３９に形成した凹条３９ａに嵌合される。
【００３０】
そして、上記心材３６における本体部３７の室外側面には、先端部を相対する方向に折り曲げてなる断面Ｌ字状の１対の係合突起部３７ｂ，３７ｂが上下に間隔をあけて突設され、これら係合突起部３７ｂ，３７ｂ間に上記防水スライド板３８が長さ方向（左右方向）にスライド可能にかつ抜け止めされて係止されている。この防水スライド板３８は、上記係合突起部３７ｂ，３７ｂ間にスライド可能に嵌合された板状の基部３８ａと、この基部３８ａの室外側面の上端部に室外側に向かうように突設された板部３８ｂと、この板部３８ｂの先端部から下方に向かって延びる板状の取付部３８ｃとからなる。
【００３１】
一方、下枠３の室外側部材４２は、目板カバー受け４３と目板カバー４４とからなり、目板カバー受け４３は上記防水スライド板３８（心材３６）の取付部３８ｃ外面に断熱パッキン４５を介して取付ビス４６により取り付けられている。目板カバー受け４３の上下端部には室外側に突出する１対の係合突起４３ａ，４３ａが一体に形成されている。
【００３２】
また、目板カバー４４は室内側に開放された断面略コ字状のもので、室内側に突出する１対の係合部４４ａ，４４ａを有しており、これら係合部４４ａ，４４ａをそれぞれ目板カバー受け４３の係合突起４３ａ，４３ａに外嵌合状態で係合させることで、目板カバー４４が目板カバー受け４３に取付ビス４６を隠すように取り付けられる。そして、上記外装材３９から室外側に露出した心材３６、つまり本体部３７の一部及び防水スライド板３８の板部３８ｂと、室外側部材４２の目板カバー受け４３とにより上記横凹溝９が設けられており、この横凹溝９にガラス板６の下縁部が収容される。
【００３３】
以上により、ガラス板６下側に位置する上記下枠３において、その室内側部材３５における心材３６の本体部３７と、それに接合された外装材３９と、室外側部材４２（目板カバー受け４３及び目板カバー４４）とにより横材本体としての下枠本体４９が構成されている。一方、上記防水スライド板３８は、上記下枠本体４９とは別体に設けられていて、該下枠本体４９に長さ方向にスライド可能に係止され、この防水スライド板３８により下枠３の横凹溝９の底部が構成されている。
【００３４】
そして、図３に示すように、上記下枠本体４９の長さＷ１（左右長さ）は左右の縦枠１，１間の間隔と略同じとされている一方、上記防水スライド板３８の長さＷ２（左右長さ）は上記下枠本体４９の長さＷ１よりも長くて形成されて上記両縦枠１，１における縦凹溝８，８内の底面間の間隔（心材１２，１２の板部１２ｂ，１２ｂ間の間隔）と略同じ長さとされており、縦枠１，１間に下枠３を配置して連結した状態では、図３及び図４に示すように、防水スライド板３８の左右の先端部が下枠本体４９の長さ方向端部から突出していて、その突出端部３８ｄ（先端部）が各縦枠１の縦凹溝８内に嵌合されている。
【００３５】
また、上記防水スライド板３８の突出端部３８ｄの先端面と縦凹溝８の底面（心材１２の板部１２ｂ）との間にはシール材としてのリボンシール５１が、また防水スライド板３８の突出端部３８ｄの室内側面と縦凹溝８の室内側面（心材１２の本体部１２ａ）との間、及び突出端部３８ｄの室外側面と縦凹溝８の室外側面（目板カバー受け１７）との間にはシール材５２，５２がそれぞれ介在されており、これらのリボンシール５１及びシール材５２により防水スライド板３８の突出端部３８ｄは各縦枠１の縦凹溝８内に液密シール状態で嵌合されている。
【００３６】
尚、図２中、５５は下枠３の横凹溝９底面（防水スライド板３８の板部３８ｂ）とガラス板６の下縁部との間に介在されたガラス板受材である。
【００３７】
また、上記各心材１２，２４，３６の本体部１２ａ，２４ａ，３７の室外側面にはガラス板６の周縁部対応して溝条のビード取付部５６が凹設され、このビード取付部５６に矩形枠状のゴム等からなるガラスビード５７が取り付けられており、このガラスビード５７により、ガラス板６の左右縁部の室内側面と縦凹溝８の室外側側面との間、ガラス板６の上縁部の室内側面と横凹溝９の室外側側面との間、及びガラス板６の下縁部の室内側面と横凹溝９の室外側側面との間がシールされる。また、ガラス板６の周縁部の室外側面と各室外側部材１６，２８，４２（目板カバー受け１７，２９，４３及び目板カバー１８，３０，４４）との間は外部シール材５８によってシールされる。
【００３８】
さらに、５９は上枠２及び下枠３における室内側部材２３，３５の心材２４，３６に一体に設けられた水平左右方向に延びるビス螺合部で、その開口端から、縦枠１における室内側部材１１の心材１２を貫通する組立ビス６０の先端部が挿入されてタッピングしながら螺合されるようになっており、この組立ビス６０の螺合締結により縦枠１，１と上枠２及び下枠３とを一体的に結合固定するようにしている。
【００３９】
したがって、この実施形態においては、建築物のフロントの外壁部Ａを組み立てるとき、縦枠１，１、上枠２及び下枠３からそれぞれ室外側部材１６，２８，４２（各目板カバー受け１７，２９，４３及び目板カバー１８，３０，４４）が外れた状態として、各々を目的の長さに切断しておく。また、下枠３の室内側部材３５における心材３６の防水スライド板３８は、所定長さＷ２に切断した後、基部３８ａにて本体部３７の係合突起部３７ｂ，３７ｂ間に挿入係止しておく。そして、左右の縦枠１，１における室内側部材１１，１１の側面に上枠２及び下枠３における室内側部材２３，３５の先端部を突き当てて両者を結合する。すなわち、各縦枠１の室内側部材１１における心材１２に各組立ビス６０を貫通させ、その先端部を上枠２及び下枠３の室内側部材における心材のビス螺合部５９に開口端から挿入してタッピングしながら螺合締結させることにより、縦枠１，１と上枠２及び下枠３とが一体的に結合固定される。
【００４０】
このとき、上記下枠３における室内側部材３５の防水スライド板３８の長さＷ２は、心材３６の本体部３７及び外装材３９、つまり下枠本体４９の長さＷ１よりも長く形成されているので、上記のように、縦枠１における室内側部材１１の側面に下枠３における室内側部材３５の先端部を突き当てて両者を結合するのに伴い、図４に示すように、防水スライド板３８の先端部が他の部分よりも突出して突出端部３８ｄとなり、この突出端部３８ｄが縦枠１の室内側部材１１における心材１２の本体部１２ａの室外面と板部１２ｂとの間のコーナ部に入り込み、この防水スライド板３８の突出端部３８ｄと心材１２の本体部１２ａの板部１２ｂとの間にリボンシール５１を介在させるとともに、突出端部３８ｄと心材１２の本体部１２ａの室外面との間隙をシール材５２でシールする。
【００４１】
次いで、縦枠１，１、上枠２及び下枠３における室内側部材１１，２３，３５の心材１２，２４，３６に形成されているビード取付部５６にガラスビード５７を取り付けた後、下枠３の防水スライド板３８上にガラス板受材５５を介してガラス板６を載置する。そして、縦枠１，１及び上枠２における室内側部材１１，２３の心材１２，２４の取付部１２ｃ，２４ｃに断熱パッキン１９，３１を介して目板カバー受け１７，２９を取付ビス２０，３２により、また下枠３における室内側部材３５の心材３６をなす防水スライド板３８の取付部３８ｃに断熱パッキン４５を介して目板カバー受け４４を取付ビス４６によりそれぞれ取付固定するとともに、防水スライド板３８の突出端部３８ｄの室外側面と目板カバー受け１７との間にシール材５２を配置し、各目板カバー受け１７，２９，４３にそれぞれ目板カバー１８，３０，４４を係合し、これら室外側部材１６，２８，４２とガラス板６の周縁部との間を外部シール材５８によりシールすればよい。このことで、各縦枠１に縦凹溝８が、また上枠２及び下枠３に横凹溝９がそれぞれ形成され、この各凹溝８，９にガラス板９の周縁部がガラスピード５７及び外部シール材５８によりシールされて嵌装収容される。
【００４２】
このように、フロントの壁部の施工時に各縦枠１に下枠３を組み付けると同時に、その下枠３の防水スライド板３８の突出端部３８ｄで縦枠１の縦凹溝８の途中を閉塞できるので、従来の溝塞ぎ部材を用いて縦凹溝８を閉塞する場合のように溝塞ぎ部材の取付忘れや外れが生じる余地はなく、防水対策を安定して確実に行うことができる。
【００４３】
また、防水スライド板３８は下枠本体４９と別体に設けられていて、その下枠本体４９にスライド可能に係止されているので、これらが一体の場合のように下枠を異なる長さに切り欠く必要はなく、予め、防水スライド板３８を下枠本体４９の長さＷ１よりも長い所定長さＷ２に切断した後に下枠本体４９に係止して取り付ければよく、施工を容易に行うことができる。
【００４４】
（実施形態２）
図５〜図８は実施形態２を示し（尚、図１〜図４と同じ部分については同じ符号を付してその詳細な説明は省略する）、縦枠１，１間に方立を立てて、この方立と各縦枠１との間に無目を配置するフロントに適用したものである。
【００４５】
この実施形態では、図５に示す如く、左右の縦枠１，１間に縦材としての方立６３が立設され、この方立６３の上端部と両縦枠１，１の上端部とは左右の上枠２，２で、また方立６３の下端部と両縦枠１，１の下端部とは左右の下枠３，３でそれぞれ連結されている。さらに、方立６３の上下中間部と両縦枠１，１の上下中間部とは横材としての左右の無目６４，６４でそれぞれ連結されている。上記縦枠１，１と各上枠２及び各下枠３との連結構造、方立６３と各上枠２及び各下枠３との連結構造はいずれも上記実施形態１と同様である。
【００４６】
上記方立６３は縦枠１と、また無目６４は下枠３（又は上枠２）とそれぞれ同じ基本構造を有するので、同じ部分については同じ符号を付してその詳細な説明を省略する。
【００４７】

BACKGROUND OF THE INVENTION
The present invention incorporates a panel plate material such as a glass plate or a decorative panel plate into a portion surrounded by a vertical material such as a vertical frame or a vertical frame, and a horizontal material such as an upper frame, a lower frame, or an eyeless structure. In particular, the present invention belongs to the technical field related to the improvement of the waterproof structure.
[0002]
[Prior art]
Conventionally, the curtain wall constituting the outer wall portion of the second floor or more of the building has an invisible tip as a horizontal member extending in the horizontal left-right direction between a plurality of vertical members extending in the vertical vertical direction. Crossing in the form of a lattice so as to face the side of the vertical, and building the outer wall of the building by incorporating panel plates such as glass plates and decorative panels in the frame surrounded by the vertical and invisible As the above-mentioned vertical and invisible, those made of aluminum, which are less susceptible to rusting, are generally used because they are exposed to wind and rain on the outer wall of the building.
[0003]
However, since this metal such as aluminum is a good heat conductor, when the vertical or invisible is cooled by the outside air in the winter, condensation occurs in the exposed part of the vertical or invisible room, There are drawbacks such as reduced heating effect due to heat transfer.
[0004]
Therefore, in order to solve such a metal vertical and invisible defects, conventionally, as shown in Patent Document 1, for example, a wooden vertical using a wooden material is used as the vertical, and the outdoor side thereof is used. A metal base material such as aluminum is fixed to the outer surface, and a slit or a long hole extending in the vertical direction is formed in this metal base material, and the metal fixture can be slid into this slit. The metal fixture on the panel material side and the wooden side are inserted into the fixture, and the inner edge member is connected to the fixture, and the vertical edge portion of the panel material is sandwiched between the inner edge member and the outer edge member. There has been proposed a structure in which the difference in thermal expansion from the vertical is absorbed by the relative movement of the fixture at the slit of the metal base material.
[0005]
By the way, when constructing a vertical member such as the above-mentioned vertical or a plain member such as an eye, the end of the transverse member is abutted against the side of the longitudinal member with a screw or the like while being cut at right angles to the length direction. It is assembled and assembled. However, vertical grooves are formed on the side surfaces of the vertical members to accommodate the horizontal edges of the panel plates such as glass plates and decorative panels, and the ends of the horizontal members are abutted against the side surfaces of the vertical members. As long as the vertical groove is left pierced up and down beyond the cross member, it cannot prevent rain leakage.
[0006]
Therefore, conventionally, by filling a groove receiving member called a sealing receptacle, groove closing piece, and mat sealer presser in the longitudinal groove, and sealing the upper surface with a sealing material, the longitudinal groove is closed at the position of the cross member. (For example, see Non-Patent Documents 1 to 3).

[Problems to be solved by the invention]
However, as in the above-described conventional non-patent documents 1 to 3, in the structure in which the groove closing member is filled in the groove and the upper surface thereof is sealed, for example, the groove closing member in the groove in advance in the manufacturing process of the cross member. Even if it is made to attach, it is inevitable that the installation will be forgotten or that the groove closing member will be detached during transportation to the construction site, and it is difficult to stably and reliably implement waterproofing measures There was a problem.
[0009]
The present invention has been made in view of such a point, and the object thereof is to improve the structure of the cross member so that the cross member is automatically closed in the middle of the longitudinal groove at the same time as the cross member is assembled to the vertical member at the time of construction. It is to be able to carry out waterproofing measures stably and reliably.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, in the present invention, attention is paid to a horizontal concave groove for accommodating a vertical edge of a panel plate material such as a glass plate in the horizontal member. It extended from the part and the front-end | tip part was fitted in the vertical concave groove of a vertical material.
[0011]
Specifically, in the first aspect of the invention, a panel is formed in a portion surrounded by a vertical member extending in the vertical vertical direction and a horizontal member whose tip is disposed so as to abut against the side surface of the vertical member and extends in the horizontal left-right direction. The premise is the outer wall structure of a building fitted with board material.
[0012]
The vertical member is formed with a vertical groove for accommodating the edge of the panel plate material in the left-right direction, and the horizontal member is formed with a horizontal groove for accommodating the edge of the panel plate material in the vertical direction. The cross member positioned at least on the lower side of the panel plate member has a cross member main body having a length substantially the same as the interval between the vertical members, and is provided separately from the cross member main body in the length direction. A waterproof slide portion that is slidably locked and located at least at the bottom of the lateral groove, and the waterproof slide portion protrudes from an end portion in the length direction of the transverse member main body, and the waterproof slide portion The projecting end portion is configured to be fitted in the above-described longitudinal groove in a liquid-tight seal state.
[0013]
According to the above configuration, when assembling the outer wall of the building, the end of the cross member is abutted against the side of the vertical member to join both, and the edge of the panel plate in the left-right direction is connected to the vertical groove of the vertical member. Moreover, each edge of a panel board | plate material is accommodated in each groove | channel by each fitting the edge part of the up-down direction of a panel board | plate material to the horizontal groove | channel of a horizontal material.
[0014]
At least the above-mentioned cross member located on the lower side of the panel plate material is slidably engaged with the cross member main body, and a waterproof slide part which is separated from the cross member main body and is located at least at the bottom of the horizontal concave groove is slidably engaged. Since the slide part protrudes from the end in the longitudinal direction of the cross member main body, as described above, when the leading end of the cross member is abutted against the side of the vertical member and the two are joined, Although it contacts the side surface of the vertical member, the protruding end portion of the waterproof slide portion enters the vertical concave groove of the vertical member. Then, by interposing a sealing material or the like between the protruding end portion of the waterproof slide portion and the inside of the vertically concave groove, the protruding end portion of the waterproof slide portion is fitted in the vertically concave groove in a liquid-tight seal state. . Therefore, at the same time that the cross member is assembled to the vertical member at the time of construction, the vertical end groove of the vertical member can be closed at the protruding end of the waterproof slide part of the cross member, so that forgetting to attach or remove the groove closing member as in the past There is no room for this, and waterproofing measures can be taken stably and reliably.
[0015]
In addition, since the waterproof slide portion of the cross member protrudes from the cross member main body, it is necessary to cut the cross member into different lengths in the cross member main body and the waterproof slide portion when both are integrated. Since the slide part is provided separately from the cross member body and is slidably locked to the cross member body, the waterproof slide part is previously cut into a predetermined length and then locked to the cross member body. It can be easily installed.
[0016]
In the invention of claim 2, the longitudinal member and the transverse member are each divided into an indoor side member and an outdoor side member, and the indoor side member includes a metal core material and an exterior material made of a wood material or a resin material. The exterior of the core material is joined and integrated so that the exterior of the core material is partially exposed from the exterior material to the outdoor side, and a groove is provided by the core material exposed from the exterior material to the outdoor side and the outdoor side member. .
[0017]
As a result, the indoor side member is formed by joining and integrating the metal core material and the exterior material so that the exterior of the core material is partially exposed from the exterior material to the outdoor side, so that the interior side of the core material is covered with the exterior material. Even if there is a temperature difference inside and outside the room, heat transfer between the room and outside is difficult, and it is not necessary to consider the thermal expansion due to the temperature difference between the metal material and wood or resin material. it can.
[0018]
Moreover, since the indoor side member is a composite material of a core material and an exterior material, the strength of the indoor side member can be secured by these core materials, and the indoor side member is formed only of a wooden material or a resin material. Compared to the above, it is possible to reduce the overall cross-sectional area of the indoor member and use a member having a small thickness.
[0019]
In the invention of claim 3, the outer wall structure of the building is used for the front, curtain wall or sash. If it carries out like this, the optimal outer wall structure of a building where the effect of the present invention is exhibited effectively will be obtained.
[0020]
