Description

【０００１】
【発明の属する技術分野】
本発明は、外壁を形成するために壁下地に並べて取り付けられた複数枚の外壁パネルシール構造に関するものである。
【０００２】
【従来の技術】
従来より、複数枚の外壁パネルを壁下地の屋外側に略水平あるいは略鉛直に並設することによって、建物の外壁を形成することが行なわれている。このような外壁の隣接する外壁パネル間には屋外側に開口する目地（隙間）が形成されており、この目地には外壁の防水性を高めるために目地パッキンが充填されている。この目地パッキンは二枚の外壁パネルを隣接させて配設した後、外壁パネルの屋外側から目地に目地パッキンを挿入することにより充填されるものである。
【０００３】
【発明が解決しようとする課題】
しかし、上記のように外壁パネルの屋外側から目地に目地パッキンを挿入する場合、外壁パネルの屋外側に作業者が入って作業できるスペースが必要であり、また、高所の目地に目地パッキンを挿入しようとする場合にはさらに足場を組むためのスペースも必要であるが、建物が密集している施工現場では外壁パネルの屋外側に上記のようなスペースを確保できないかあるいは非常に狭いスペースしか確保できないことがあり、目地パッキンの施工が行えないあるいは行ないにくいという問題があった。
【０００４】
本発明は上記の点に鑑みてなされたものであり、目地パッキンの施工を容易に行うことができる外壁パネルシール構造を提供することを目的とするものであり、特に、外壁パネルの屋外側に充分な作業スペースが確保できない場合に好適に用いることができる外壁パネルシール構造を提供することを目的とするものである。
【０００５】
【課題を解決するための手段】
本発明の請求項１に係る外壁パネルシール構造は、壁下地５に取り付けた隣接する外壁パネル１、２間に目地パッキン３を配設してなる外壁パネルシール構造において、ボルト等の固定具４の基端部に支持材６を介して目地パッキン３を取り付け、隣接する外壁パネル１、２間の目地２８に固定具４を挿入して係止して目地パッキン３を目地２８に配設して成り、
前記支持材６は一対の支持材半体３３，３３を組み合わせて構成され、前記支持材半体３３は、本体部３４と、本体部３４から屋外側に向かって突出する係止部３６とを有し、本体部３４の屋内側の背部３４ａを貫通すると共にこの背部３４ａの先端に開口する半孔３７が形成されており、
固定具４の頭部４ａを本体部３４に収納するようにして一対の支持材半体３３，３３を結合して支持材６が形成されると共に固定具４の基端部と支持材６とが連結され、支持材６の係止部３６を目地パッキン３の係止溝３２に差し込むことで固定具４の基端部に支持材６を介して目地パッキン３が取り付けられていることを特徴とするものであり、外壁パネル１、２より屋内側の作業で目地パッキン３を隣接する外壁パネル１、２間の目地２８に配設することができ、外壁パネル１、２の屋外側に充分な作業スペースが確保できない場合でも、目地パッキン３の施工を容易に行うことができるものである。
【０００６】
また、本発明の請求項２に係る外壁パネルシール構造は、請求項１に加えて、長尺の支持材６に複数本の固定具４を設け、支持材６の全長に亘って目地パッキン３を取り付けることによって、支持材６を介して固定具４の基端部に目地パッキン３を取り付けて成ることを特徴するものであり、長尺で柔軟性のある目地パッキン３を支持材６で支持しながら隣接する外壁パネル１、２間の目地２８に配設することができ、目地パッキン３の施工をさらに容易に行うことができるものである。
【０００７】
また、本発明の請求項３に係る外壁パネルシール構造は、請求項１又は２に加えて、目地パッキン３の屋内側に排水樋材７を設けて成ることを特徴とするものであり、目地パッキン３の屋内側に浸入した雨水等の水を排水樋材７で排水することができ、外壁の防水性を高めることができるものである。
【０００８】
また、本発明の請求項４に係る外壁パネルシール構造は、請求項３に加えて、排水樋材７に貫通孔８を形成し、貫通孔８を通して固定具４を配設し、貫通孔８と固定具４との隙間を閉塞する貫通孔パッキン９を固定具４の外周に装着して成ることを特徴とするものであり、貫通孔８を通して固定具４を操作することによって目地２８に目地パッキン３を配設することができ、目地パッキン３の屋内側に排水樋材７を設けても目地パッキン３の施工性を損なわないようにすることができるものであり、しかも、貫通孔パッキン９で貫通孔８と固定具４との隙間を閉塞することによって、貫通孔８と固定具４との隙間を通じて雨水等の水が排水樋材７の屋内側に浸入するのを防止することができ、排水樋材７に貫通孔８を設けても外壁の防水性を損なわないようにすることができるものである。
【０００９】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【００１０】
図１に略水平方向に隣接する外壁パネル１、２間のシール構造を示す。外壁パネル１、２は表面板２０と裏面板２１との間に芯材２２を充填して形成されるものである。表面板２０と裏面板２１としては耐食性に優れる金属板を用いることができ、例えば、ステンレス鋼板、亜鉛めっき鋼板、塗装鋼板等の公知のものを用いることができる。また、芯材２２としては断熱性及び耐火性に優れるものを用いることができ、例えば、グラスウール、ロックウール、フェノールフォーム、ウレタンフォーム等の公知のものを用いることができる。
【００１１】
外壁パネル１、２の側端部には突出片２３が略全長に亘って突設されている。突出片２３は表面板２０の側端部に略水平に延設された延設部２４と、延設部２４の先端から屋内側に向かって略直角に屈曲形成された密着部２５と、密着部２５の先端から外側（芯材３と反対側）に向かって略直角に屈曲形成された支え部２６とで構成されている。また、突出片２３の屋内側の空間、すなわち、芯材２２の側端面と延設部２４と密着部２５で囲まれた空間にはパネルパッキン２７が外壁パネル１、２の鉛直方向の略全長に亘って充填されている。
【００１２】
そして、突出片２３の密着部２５を対向させるようにして二枚の外壁パネル１、２を略水平に隣接させることによって、対向する密着部２５の間の空間を目地２８として形成するものである。また、目地２８の屋内側において、隣接する外壁パネル１、２の芯材２２、２２間の空間は樋収納部３０として形成するものである。また、隣接する突出片２３の支え部２６の先端間には目地２８と樋収納部３０とを連通させるための間隙２９を設けるようにするものである。
【００１３】
目地パッキン３はＥＰＤＭなどの柔軟性及び弾性のあるゴム材料等で形成されるものである。また、目地パッキン３は鉛直方向に長尺な角材状に形成されていると共に目地パッキン３の両側面には複数個の防水片３１が全長に亘って突設されている。さらに、目地パッキン３にはその背面（屋内側面）に開口する係止溝３２が全長に亘って形成されている。
【００１４】
そして、上記の目地パッキン３は目地２８の鉛直方向の全長に亘って充填されている。この時、目地パッキン３の防水片３１は屋外側に向かって倒れた状態で両側の密着部２５の表面に当接している。また、目地パッキン３の係止溝３２の開口の位置は間隙２９の位置と合致しており、係止溝３２の開口以外において目地パッキン３の背面は両側の支え部２６の表面に密着している。
【００１５】
上記の目地パッキン３は支持材６に取り付けられて支持されている。支持材６は鉛直方向に長尺に形成されるものであって、支え部２６の屋内側において樋収納部３０の鉛直方向の略全長に亘って配置されている。支持材６は一対の支持材半体３３を組み合わせることにより形成されている。図２（ａ）に示すように支持材半体３３は、断面略コ字状の本体部３４と、本体部３４から前側（屋外側）に向かって突出する挿入部３５と、挿入部３５の先端から後側斜め（屋内側斜め）に向かって突出する係止部３６とを備えて形成されている。また、図２（ｂ）に示すように、本体部３４の背部（屋内側の部分）３４ａを貫通する半孔３７が形成されている。この半孔３７は本体部３４の背部３４ａの先端にも開口されている。支持材半体３３にはその長手方向に沿って複数個の半孔３７が設けられており、隣り合う半孔３７の間隔は例えば３００ｍｍにすることができる。
【００１６】
そして、一対の支持材半体３３を係止部３６同士が向かい合わないようにして線対称に配置すると共に一対の支持材半体３３の挿入部３５同士を両面テープ等で接着することによって支持材６を形成することができる。この時、一方の支持材半体３３の背部３４ａと他方の支持材半体３３の背部３４ａとは前後方向（屋内外方向）に重ねられると共に一方の支持材半体３３の半孔３７と他方の支持材半体３３の半孔３７とが合致した状態となっている。
【００１７】
このようにして形成した支持材６の両方の係止部３６を目地パッキン３の係止溝３２に背面の開口から差し込んで係止溝３２内の開口縁部に係止することによって、支持材６と目地パッキン３を結合することができる。この時、支持材６の本体部３４は目地２８の背面側（屋内側）に配置されており、支持材６の挿入部３５が間隙２９を通って目地２８内に挿入されており、目地２８内において目地パッキン３と支持材６とは上記のように結合されている。
【００１８】
支持材６にはボルト等で形成される複数本の固定具４が設けられている。固定具４はその頭部４ａを支持材６の本体部３４の間の空間に収納されており、固定具４のネジ部４ｂは支持材６の半孔３７から屋内側に突出されている。また、固定具４の頭部４ａは半孔３７の開口縁部に係止されている。また、固定具４のネジ部４ｂは排水樋材７と樋下地材３８と座金３９とを貫通して外壁パネル１、２の屋内側に突出しており、ネジ部４ｂにナット４０を螺合することにより固定具４は座金３９に係止されて取り付けられている。
【００１９】
排水樋材７は屋外側に開口する断面略コ字状で長尺に形成されるものであって、樋収納部３０内に鉛直方向に長く配設されている。また、排水樋材７の端部は外壁パネル１、２のパネルパッキン２７の屋内側面に食い込ませている。
【００２０】
樋下地材３８は、屋内側に開口する断面略ハット状に形成される下地本体４１と、下地本体４１の開口を閉塞する塞ぎ板４２と、下地本体４１と塞ぎ板４２の間に充填された珪酸カルシウムなどの耐火材４３とで長尺に形成されており、排水樋材７の屋内側において樋収納部３０内に鉛直方向に長く配設されている。また、樋下地材３８の側端部は取付片４４として形成されており、取付片４４は壁下地５の添え胴縁４５と外壁パネル１、２との間に差し込まれて添え胴縁４５に固定されている。この樋下地材３８は排水樋材７の背面に当接あるいは接着して排水樋材７を支持するものである。
【００２１】
また、排水樋材７の背部７ａ及び樋下地材３８には屋内外方向に貫通する複数個の貫通孔８が形成されており、各貫通孔８には固定具４のネジ部４ｂが挿通されている。また、排水樋材７の背部７ａと支持材６の本体部３４との間において固定具４のネジ部４ｂには貫通孔パッキン９が装着されており、この貫通孔パッキン９を排水樋材７の背部７ａの屋外側面に密着させることによって、排水樋材７の背部７ａに形成された貫通孔８の開口縁部と固定具４のネジ部４ｂとの間の隙間が閉塞されている。
【００２２】
座金３９は隣接する壁下地５の添え胴縁４５の間に架設されている。
【００２３】
次に、上記のような外壁パネルのシール構造の施工方法の一例を説明する。
【００２４】
壁下地５は胴縁４６及び添え胴縁４５とで構成されている。胴縁４６はリップ溝型鋼等で形成されるものであって、鉛直方向に長く配設されている。添え胴縁４５はＬ型鋼等で形成されるものであって、鉛直方向に長く配設されると共に胴縁４６の側面に固着されている。このような複数本の壁下地５は所定の間隔を介して水平方向に並べて配設されている。
【００２５】
また、目地パッキン３、支持体６、固定具４、貫通孔パッキン９は施工する前に予め組み立てておく。この組み立ては次のようにして行なう。まず、一対の支持材半体３３の本体部３４内に固定具４の頭部４ａを収納するようにして一対の支持材半体３３を結合して支持材６を形成すると共に複数個の固定具４の基端部と支持材６とを連結する。次に、各固定具４のネジ部４ｂに貫通孔パッキン９を差し込んで挿着する。また、支持材６の係止部３６を目地パッキン３の係止溝３２に差し込んで係止溝３２内の開口縁部に係止することによって、固定具４の基端部に支持材６を介して目地パッキン３を取り付ける。このようにして目地パッキン３、支持体６、固定具４、貫通孔パッキン９からなる組み合わせ体５５を形成する。
【００２６】
また、排水樋材７と樋下地材３８は施工する前に予め組み立てておく。この組み立ては、樋下地材３８の下地本体４１の屋外側面に排水樋材７の屋内側面（背面）を接着等することによって行うことができる。
【００２７】
そして、まず、排水樋材７と樋下地材３８を組み立てたものを隣り合う添え胴縁４５、４５の屋外側に配置し、樋下地材３８の取付片４４を添え胴縁４５にビス等の固定具で固定することによって、排水樋材７と樋下地材３８を隣り合う添え胴縁４５、４５に亘るように取り付けられるものであり、排水樋材７及び樋下地材３８は隣り合う添え胴縁４５、４５の先端間の間隙５６の屋外側に位置するものである。次に、排水樋材７の背部７ａと樋下地材３８とを貫通する貫通孔８を屋内側より形成する。この貫通孔８の屋内側の開口は隣り合う添え胴縁４５、４５の先端間の間隙５６に露出するように形成されている。尚、この貫通孔８は排水樋材７と樋下地材３８を添え胴縁４５に取り付ける前に形成しておいてもよい。
【００２８】
次に、一方の外壁パネル１に固定ボルト５０を設ける。固定ボルト５０は外壁パネル１の側端部を厚み方向に貫通するように挿着されるものであり、固定ボルト５０の頭部５１は外壁パネル１の屋外側面に設けた水平方向の凹溝５２内に収納されている。次に、固定ボルト５０を設けた外壁パネル１を壁下地５の屋外側に配置する。外壁パネル１の配置は壁下地５の屋外側から行なうようにする。次に、外壁パネル１の屋内側面に突出した固定ボルト５０の先端を添え胴縁４５のボルト孔５３に屋外側から挿入すると共に添え胴縁４５の屋内側に突出した固定ボルト５０の先端に固定ナット５４を螺合する。このようにして外壁パネル１を壁下地５に取り付けて固定する。この時、樋下地材３８の一方の取付片４４は外壁パネル１と壁下地５の添え胴縁４５の間に介在すると共に排水樋材７の一方の先端は外壁パネル１のパネルパッキン２７に弾接するものである。
【００２９】
上記のようにして一方の外壁パネル１を壁下地５に取り付けた後、組み合わせ体５５の配置を壁下地５の屋外側から行なう。つまり、図３に示すように、組み合わせ体５５の固定具４のネジ部４ｂを貫通孔８に屋外側の開口から挿入し、貫通孔８の屋内側の開口及び間隙５６を通して固定具４のネジ部４ｂを添え胴縁４５よりも屋内側に突出させる。次に、固定具４のネジ部４ｂを添え胴縁４５よりも屋内側から引張ることにより、貫通孔パッキン９と支持材６及び目地パッキン３を屋内側方向に向かって移動させる。このようにして貫通孔パッキン９を排水樋材７の背部７ａの屋外側面に当接させると共に目地パッキン３を外壁パネル１の密着部２５の外面と支え部２６の屋外側面に当接させるものであり、これにより、目地２８となる箇所に目地パッキン３が配置される。また、支持具６及び貫通孔パッキン９は壁下地５に取り付けた外壁パネル１の支え部２６と排水樋材７の背部７ａとの間に配置される。
【００３０】
次に、上記外壁パネル１とは別の外壁パネル２を取り付ける。この外壁パネル２は上記外壁パネル１を取り付けた壁下地５と隣接する他の壁下地５に取り付けられるものである。また、外壁パネル２にも上記外壁パネル１と同様に固定ボルト５０が設けられている。そして、固定ボルト５０を設けた外壁パネル２を壁下地５の屋外側に配置する。外壁パネル２の配置も壁下地５の屋外側から行なうようにする。次に、外壁パネル２の屋内側面に突出した固定ボルト５０の先端を上記添え胴縁４５と隣接する他の添え胴縁４５のボルト孔５３に屋外側から挿入すると共に添え胴縁４５の屋内側に突出した固定ボルト５０の先端に固定ナット５４を螺合する。このようにして外壁パネル２を壁下地５に取り付けて固定する。この時、外壁パネル１と外壁パネル２は側端部同士が対向するように配設される。また、樋下地材３８のもう一方の取付片４４は外壁パネル２と壁下地５の添え胴縁４５の間に挿入されると共に排水樋材７のもう一方の先端は外壁パネル２のパネルパッキン２７に弾接させるようにする。さらに、外壁パネル２の支え部２６を上記のように配置した目地パッキン３と支持体６の間に差し込んで、目地パッキン３を外壁パネル２の密着部２５の外面と支え部２６の屋外側面に当接させる。
【００３１】
次に、添え胴縁４５よりも屋内側に突出する固定具４のネジ部４ｂに座金３９を装着すると共に座金３９よりも屋内側に突出する固定具４のネジ部４ｂにナット４０を螺合して締め付けることによって、固定具４を座金３９に係止して固定する。また、このナット４０の締め付けにより、固定具４が屋内側から引張られて貫通孔パッキン９と支持材６及び目地パッキン３を屋内側方向に向かって移動することになり、これにより、貫通孔パッキン９を排水樋材７の背部７ａの屋外側面に密着させることができ、貫通孔８の屋外側の開口と固定具４のネジ部４ｂとの間の隙間を閉塞することができると共に、目地パッキン３を外壁パネル１、２の密着部２５の外面と支え部２６の屋外側面に密着させることができるものである。
【００３２】
そして、上記の外壁パネル１、２の施工を順次繰り返していくことにより、複数枚の外壁パネル１、２で建物の外壁を形成することができるものである。
【００３３】
図４に他の実施の形態を示す。この実施の形態は目地パッキン３の形状及び支持材６の形状が上記実施の形態と異なり、その他の構成は上記実施の形態と同様である。目地パッキン３の係止溝３２は断面略Ｔ字状に形成されており、従って、支持材６の挿入部３５及び係止部３６も断面略Ｔ字状に形成されている。また、目地パッキン３の厚み寸法（屋内外方向の寸法）は目地２８の深さ寸法（屋内外方向の寸法）とほぼ同じに形成されており、従って、目地２８に目地パッキン３を充填すると、外壁パネル１、２の屋外側面と目地パッキン３の屋外側面とがほぼ面一となるものである。また、目地パッキン３の屋内側面にはシーリングテープ５８が貼り付けてあって、シーリングテープ５８が支え部２６に密着することになってさらに防水性を高めることができるものである。
【００３４】
尚、上記では鉛直方向に長い目地２８について説明したが、本発明は水平方向に長い目地に適用することも可能である。
【００３５】
【発明の効果】
上記のように本発明の請求項１の発明は、壁下地に取り付けた隣接する外壁パネル間に目地パッキンを配設してなる外壁パネルシール構造において、ボルト等の固定具の基端部に支持材を介して目地パッキンを取り付け、隣接する外壁パネル間の目地に固定具を挿入して係止して目地パッキンを目地に配設して成り、前記支持材は一対の支持材半体を組み合わせて構成され、前記支持材半体は、本体部と、本体部から屋外側に向かって突出する係止部とを有し、本体部の屋内側の背部を貫通すると共にこの背部の先端に開口する半孔が形成されており、固定具の頭部を本体部に収納するようにして一対の支持材半体を結合して支持材が形成されると共に固定具の基端部と支持材とが連結され、支持材の係止部を目地パッキンの係止溝に差し込むことで固定具の基端部に支持材を介して目地パッキンが取り付けられていることを特徴とするものであり、目地への目地パッキンの施工を容易に行うことができるものであり、特に、外壁パネルの屋内側の作業で目地パッキンを隣接する外壁パネル間に配設することができ、外壁パネルの屋外側に充分な作業スペースが確保できない場合でも、目地パッキンの施工を容易に行うことができるものである。
【００３６】
また、本発明の請求項２の発明は、長尺の支持材に複数本の固定具を設け、支持材の全長に亘って目地パッキンを取り付けることによって、支持材を介して固定具の基端部に目地パッキンを取り付けて成ることを特徴するものであり、長尺で柔軟性のある目地パッキンを支持材で支持しながら隣接する外壁パネル間の目地に配設することができ、目地パッキンの施工をさらに容易に行うことができるものである。
【００３７】
また、本発明の請求項３の発明は、目地パッキンの屋内側に排水樋材を設けて成ることを特徴とするものであり、目地パッキンの屋内側に浸入した雨水等の水を排水樋材で排水することができ、外壁の防水性を高めることができるものである。
