Description

【０００１】
【発明の属する技術分野】
この発明は、配列されたパネルによって外壁が構成される建物の外壁構造に関する。
【０００２】
【従来の技術】
建物の外壁構造で外装パネルを用いるものでは、パネルが上下左右に配列されて外装面が構成されており、パネル間に形成される隙間、すなわち目地には、防水性や意匠性の付与のために湿式あるいは乾式の目地材が施工されている。このうち、縦目地または横目地の少なくともどちらか一方に乾式の目地材を施工する外壁構造では、縦目地と横目地との交差部分で、縦目地に施工される縦目地材を途切れさせ横目地に施工される横目地材を連続させる「横がち」の構成とすることがある。この構成では、縦目地材を流れ落ちた水が交差部分の横目地の上に溜まりやすい。溜まった水は、パネルと目地材との隙間から室内側に浸入したり、セラミック系ボードやコンクリートボードのように吸水性を有する外装パネルの表面からパネル内部にしみ込んだりするおそれがある。パネル内部に水が浸入すると、ボードの腐食や劣化が早まったり、浸入した水が凍結による体積膨張を繰り返すことによってボードが徐々に破壊されたりするおそれがある。
このような不具合を解消するために、縦目地に乾式目地部材を用い、横目地に沿ってパネルの室内側から下側パネルの上端を被覆し、かつパネルの室内側から室外側に向かって下方に傾斜する長尺板状の水受け部材を設ける外壁構造がある。この外壁構造では、縦目地部材に沿って流れ落ちる水を水受け部材で受け止めて室外側に排水することができる。
【０００３】
【発明が解決しようとする課題】
しかしながら、この構成では、水受け部材と上側のパネルとの間に、水が流れるのに十分な隙間を設けなければならない。この結果、建物の外から隙間や水受け部材が見えてしまい、外観を損ねるおそれがある。特に、吸水性を有するパネルを用いる場合、上側パネルの下端面からパネルに水がしみ込むのを防ぐために、上側パネルの下端が水受け部材上を流れる水に接触しないように、上下パネル間の隙間をより大きく設けなければならない。したがって、上下パネル間の隙間がはっきり視認され、建物の外観が損なわれるおそれが高い。
【０００４】
そこで、本発明では、配列されたパネルを備える建物の外壁構造において、横目地部分の外観の低下が抑制され、かつパネル内部への水の浸入が抑制されているとともに排水性の良好な建物の外壁防水構造を提供することを課題とする。
【０００５】
【課題を解決するための手段】
上記課題を解決するため、本発明では、複数の外装パネルが上下左右に配列されており、左右に隣接するパネル及び上下に隣接するパネルの端面間にそれぞれ縦目地と横目地とが形成される建物の外壁防水構造であって、縦目地に沿って縦目地を塞ぐ長尺状の目地材が配置されており横目地取付け部材と、横目地部材と、水受け部材とを備え、前記水受け部材は、横目地の下側に位置するパネルの上端面を覆い、かつ室外側の先端が下方を指向するように形成されており、前記横目地取付け部材は、横目地の、上側に位置するパネルの裏面下端部に固定される固定部と、固定部から延びて横目地内に配置されて横目地部材を保持可能な形状を有する横目地取り付け部とを備え、前記横目地部材は、長尺状に形成され、横目地とともに前記水受け部材及び前記横目地取付け部材の横目地取り付け部を室外側から隠蔽する意匠部と、意匠部の裏側から突出して形成されて前記横目地取り付け部に保持される形状を有する脚部とを備えており、横目地取付け部材又は横目地部材と上側パネルの下端面との間にシール部が形成されていることを特徴とする建物の外壁防水構造を提供する。
この建物の外壁防水構造では、水受け部材によって横目地の下側パネルの上端が覆われることによって下側パネルの上端が水から遮断されている。このため、下側パネルの上端が水受け部材上を流れる水に接触することなく良好に水を排出することができる。また、横目地取付け部材又は横目地部材と上側パネルの下端面との間にシール部が形成されているため、上側パネルの下端面に上側パネル外面を流れ落ちる水や水受け部材上を流れる水が接触するおそれがなく、この部分からパネルより室内側の外壁構造部分やパネル内部に水が浸入することが回避されている。また、上側パネルの下端面と水受け部材を流れる水との接触を考慮しなくても良いため、目地幅を小さくすることができる。
また、横目地、横目地取り付け部材、及び水受け部材は、横目地部材の意匠部によって室外側から隠蔽されている。したがって、建物の外観の低下を抑制して、良好な排水機構を備え、かつパネルを防水した外壁防水構造とすることができる。
【０００６】
また、本発明では、上記外壁防水構造であって、前記横目地取付け部材の横目地取り付け部は、パネルの外側に向けて開口する溝状部を備え、前記横目地部材の脚部は、前記溝状部に挿入されて係合固定されている外壁防水構造を提供する。
この外壁防水構造では、横目地取付け部材の溝状部に横目地部材の脚部を外側から挿入して、横目地部材を係合固定できる。したがって、接着などしなくても良く、取り付け作業が容易である。また、例えば、横目地部材が老朽化したり破損したり、あるいは改装によって模様替えしたりする際に、横目地部材のみの交換が可能である。
【０００７】
また、本発明では、上記いずれかの外壁防水構造であって、前記横目地取り付け部材は、芯材を形成する硬質の剛性を有する材料と、芯材を被覆する被覆層を形成し、芯材よりも軟質で弾力性を有する材料との複合押出し部材である外壁防水構造を提供する。
この外壁防水構造によれば、横目地取付け部材を、硬質で剛性を有する材料からなる芯材とこの芯材を被覆する軟質で弾力性を有する材料とで構成することにより、所定の強度を確保し、かつ表面に柔軟性、弾力性を付与できる。さらに、横目地取付け部材の軟質の材料で形成された部分を上側パネルの下端面に密着させることにより、横目地取付け部材の上側パネルへの密着部分をシール部として作用させることができる。また、芯材が硬質の剛性材料からなるため、全体形状が変形しにくく、成形、運搬、施工などの際に取り扱いやすい。
【０００８】
また、本発明では、上記いずれかの外壁防水構造であって、前記シール部は、テープ状で接着性を有するシール材を有している外壁防水構造を提供する。
この外壁防水構造では、パネルの下端面に接着しやすいなど、よりシールに適した性質を備えるシール材を選択することができ、パネル下端面と横目地取付け部材または横目地部材との間のシール性を向上させることができる。また、テープ状に形成されたシール材を用いることにより、パネルの下端面の長手方向に沿って安定して密に接するシール部を形成することが容易である。
【０００９】
また、上記いずれかの外壁防水構造であって、前記横目地部材は、芯材を形成し硬質で剛性を有する材料と、芯材を被覆する被覆層を形成し、芯材よりも軟質で弾力性を有する材料との複合押出し部材である外壁防水構造を提供する。
この外壁防水構造によれば、横目地部材を硬質で剛性を有する材料からなる芯材とこの芯材を被覆する軟質で弾力性を有する材料とで構成することにより、所定の強度を確保し、かつ表面に柔軟性、弾力性を付与できる。さらに、横目地部材の軟質の材料で形成された部分を上側パネルの下端面に密着させることにより、横目地取付け部材の上側パネルへの密着部分をシール部として作用させることができる。また、芯材が硬質の剛性材料からなるため、全体形状が変形しにくく、成形、運搬、施工などの際に取り扱いやすい。
【００１０】
また、上記いずれかの外壁防水構造であって、前記横目地部材の脚部は、縦目地材が配置される位置に対応して部分的に除去され、縦目地材は、前記除去された部分を通って下方に延びている外壁防水構造を提供する。
横目地部材の脚部は、縦目地材が配置される位置に対応して部分的に除去されているため、縦目地材をつたって流れ落ちる水の通路が横目地部材の脚部によって遮られることがなく、排水性が良好に維持されている。さらに、横目地部材の脚部の除去された部分を通って縦目地を流れ落ちる水が縦目地材に沿って水受け部材まで良好に流れることにより、排水性がより良好となっている。
【００１１】
また、上記いずれかの外壁防水構造であって、前記横目地部材及び／又は前記横目地取付け部材には、横目地部材と横目地取り付け部材の横目地取り付け部との間に形成される隙間をシールする密閉部が形成されている外壁防水構造を提供する。
この外壁防水構造では、横目地部材または横目地取付け部材に一体に密閉部を設けることにより、別部材を施工することなく横目地部材の脚部と横目地取付け部材との間に形成される隙間を室外側からシールして、水の浸入を回避できる。
【００１２】
また、本発明では、上記外壁防水構造であって、横目地が縦目地と交差する部分において、前記水受け部材と前記横目地部材の意匠部は左右のパネルにわたって延びており、前記横目地取り付け部材と横目地部材の脚部とは、左右方向において左右のパネルの側端面に対応する位置に対向する端部をそれぞれ有しており、前記縦目地材は、この端部間に配置されている外壁防水構造を提供する。
この外壁防水構造では、横目地部材の意匠部は、左右のパネルにわたって一体に連続して延びているため、横目地の継ぎ目と縦目地とが同一直線上に並ぶことがなく、縦目地部分の横目地の外観が低下しない。また、横目地部材の脚部及び横目地取付け部材の横目地取り付け部の端部は、それぞれパネルの側端面までで途切れており、縦目地内には存在しないため、縦目地部分を通って横目地まで流れ落ちた水が水受け部材まで良好に流れ落ちることができる。また、この端部間に縦目地材が通されて端部よりも下方に延びていることにより、縦目地を流れ落ちる水が縦目地材に沿って水受け部材まで確実に誘導されるため、排水性がより良好となっている。また、パネル下端から水受け部材までの縦方向に空間が形成されているため、これによって縦目地材の長さや取付位置の誤差を吸収するようにすることもできる。
【００１３】
【発明の実施の形態】
次に本発明の実施の形態について、図面を参照しながら詳細に説明する。
図１〜５に本発明の一実施の形態に係る外壁防水構造１を示す。外壁防水構造１は、複数のパネル３，３，５，５が上下左右に配列されて、建物の外装面を構成している。
パネル３，５は、建物の外壁を構成しうる公知の種々のパネル材である。図２，３，５に示すように、パネル３，５には、パネル３，５の裏面に複数本の鉄フレームが矩形に組み立てられている枠体７が取り付けられている。パネル３，５は、枠体７を介して、建物の骨格部分９にボルト締めなど公知の手段によって取り付けられている。
【００１４】
図１に示すように、左右のパネル３−３，５−５間には縦目地が形成されており、縦目地には縦目地材２９が取り付けられている。また、上下のパネル３−５間には横目地が形成されている。横目地には、図２〜５に示すように水受け部材１０、横目地取り付け部材３０及び横目地部材５０が取り付けられている。水受け部材１０、横目地取り付け部材３０及び横目地部材５０を備える本発明にかかる構成は、例えば、１階と２階との境界部分や２階と３階との境界部分などにおいて実施される。
【００１５】
横目地部分の構造について、図２〜５を参照して詳細に説明する。なお、図２〜５は、それぞれ図１のII−II線、III−III線、IV−IV線、V−V線における断面図である。
水受け部材１０は、パネルの裏面側に取り付けられて、横目地に設置され下側パネルの上端面を覆い、横目地内に浸入した水を外側に排水する部材である。水受け部材１０は、横目地に沿って取り付けられる長尺部材である。
【００１６】
水受け部材１０は、その長手方向に沿って延びる被覆部１４と水切り部１５とを備えている。被覆部１４は、下側パネル５の上端面を被覆するとともに、水を外側に誘導する部位である。
水切り部１５は、被覆部１４によって外側まで誘導された水を排出する部位で、被覆部１４から連続して延出して形成されており、水受け部材１０の室外側の端部となっている。
【００１７】
本実施形態の水受け部材１０は、図２中紙面に垂直な方向に延びる長尺状部材であり、長手方向に連続して所定の横断面になるよう、金属製の平板を曲げ加工するなどして得られる部材である。ここで、この水受け部材１０は、その横断面において室内側から順に取り付け端部１２、中継部１３、被覆部１４及び水切り部１５を備えている。取り付け端部１２は、外壁防水構造１の一部として骨格部分９に取り付けられた状態において水平に延びる平板状に形成されている。そして、中継部１３は、外壁防水構造１に取り付けられた状態において、取り付け端部１２の室外側端部から下方にほぼ直角に屈曲されたのち、室外側に向けて約９０°湾曲されて水平に延びる略L字状の横断面を有するように形成されている。次に、被覆部１４は、中継部１３に対して所定の角度に屈曲されて、斜め下方に延びる板状に形成されている。被覆部１４は、図２に示すように、中途に水平からの傾斜角を小さくする屈曲部を備えている。被覆部１４は、室内外方向に、外壁防水構造１の下側パネル５の厚み以上の幅を備えている。そして、水切り部１５は、被覆部１４の室外側の端部が屈曲されて鉛直下方に延びる板状に形成されている。水切り部１５の先端は、テーパ状の先細に形成されており、水切れが良好な形状とされている。
【００１８】
水受け部材１０は、図示しないねじなどによって、外壁防水構造１の骨格部分９に取り付け端部１２が取り付けられて固着されている。このとき、被覆部１４は、下側パネル５の上端面を上側から覆うとともに、その上面は室内側から外側へ向かってやや下傾するように配置されている。被覆部１４は、横目地の内部に配置されており、横目地内に浸入した水を、その上面で受けて室外側に誘導できるように形成されている。水切り部１５は、下側パネル５の外面より室外側に配置されており、被覆部１４によって室外側に向けて誘導された水を下側パネルの外面より外側の下方へ流し落とす。
なお、本実施形態では、図２に示すように被覆部１４と下側パネル５の上端面との間に独立気泡スポンジなどで構成される弾性シール材２１が設けられている。弾性シール材２１は、室内側への水の浸入を阻止するとともに被覆部１４と下側パネル５の上端面との距離の誤差を吸収して被覆部１４を下側パネル５の上方に安定に保持している。
【００１９】
また、図２に示すように、中継部１３の上方には、独立気泡のスポンジなどで構成される弾性シール材１７を介して止水部材１９が配置されている。止水部材１９は、折り曲げ成形された薄板状部材で、水受け部材１０の中継部１３から上方に延びて上側パネル３の室内側に向かうように形成されている。本実施形態の中継部１３は、被覆部１４の上面を通る水が室内側へ流れ込むのを防ぐ堰の役割を果たしている。中継部１３、弾性シール材１７、及び止水部材１９によってパネル３，５間で室内側への水の浸入が防止されている。
【００２０】
水受け部材１０は、図１に示す外壁防水構造１の横目地に沿って取り付けられ、少なくとも横目地と縦目地との交差部分では連続するように配置される。好ましくは、横目地全体に沿って配置される。本実施形態では、水受け部材１０は、パネル３，５の横方向の長さより長い長尺状に形成されており、図１及び５に示すように、縦目地以外の部分（パネル３，５に対応する部分）に端部が位置するように配置されている。そして、水受け部材の継ぎ目においては、隣接する水受け部材１０の互いに対向する端部間にわたって水受け連結部材２３が設けられて、端部間の防水性が確保されている。
【００２１】
水受け連結部材２３は、取り付け端部を有しない他は、水受け部材１０と同様の横断面形状に形成された板状部材である。図５に示すように、水受け連結部材２３は、水受け部材１０の上面に重ね合わされた状態で、互いに隣接する水受け部材１０の端部間にわたって配置される。水受け連結部材２３が設けられる部分では、水受け連結部材２３の中継部１３に対応する面に弾性シール材１７ａが設けられ、弾性シール材１７ａを介して止水部材１９が連結されている。
なお、水受け部材１０の連結は、対向する端部間にペースト状のコーキング剤を吐出してシールするなど、公知の他の連結方法によっても良い。また、水受け部材１０の端部は、パネル３，５の中間に限定されず、パネル３，５の側端面と一致する位置や、縦目地の範囲内に配置されても良い。
【００２２】
横目地取付け部材３０は、上側パネル３の裏面下端部に固定される固定部３２と、固定部３２から延びて横目地内に配置されて横目地部材５０を保持する形状を有する横目地取り付け部３４とを備える部材である。横目地取付け部材３０は、水受け部材１０と同様、横目地に沿って取り付けられる部材で、好ましくは、長尺状に形成される。
【００２３】
固定部３２は、係合、嵌合、接着、あるいはネジなどの固定部材を用いる公知の固定方法によって上側パネルの裏面下端部に固定される部分である。なお、本明細書において、「固定部の上側パネル３の裏面下端部への固定」とは、パネル３の裏面に直接取り付けられることに限定されず、例えば枠体７など、パネル３の裏面に一体的に取り付けられている部材を介して固定される形態も含むものとする。
【００２４】
横目地取り付け部３４は、横目地部材５０を取り付けることができる種々の形状に形成される。横目地取り付け部３４は、横目地取り付け部材３０が上側パネル３の裏面下端部に固定された状態で、横目地部材５０をパネル３の室外側から挿入して取り付けられる形状とされることが好ましい。具体的には、横目地取り付け部３４と横目地部材５０の脚部５４とが係合して固定される形状が好ましい。横目地取り付け部３４は、横目地内のどの部分に配置されても良いが、好ましくは、上側パネル３に近接して配置される。
【００２５】
図２，３，５に示す横目地取付け部材３０では、固定部３２は、段差を有する板状に形成されており、図示しない貫通孔を備えている。横目地取り付け部３４は、固定部３２の下端に連続して形成されており、外側に向けて開口する溝状部３６を備えている。溝状部３６は、室内外方向に奥行きを有し、横断面において固定部３２の延長線上に底部を有する断面コの字状に形成されている。溝状部３６を形成し上下方向で対向する上下の壁部の内側面には、溝状部３６の中心に向かって突出する複数の弾性変形可能な係止片３８が形成されている。また、横目地取り付け部材３０は、横目地取り付け部３４の下側の壁部の室外側端部から下方へ延びる延長部４０を備えている。延長部４０は、横目地取り付け部３４に固定された横目地部材５０に対してより大きな面積で接することによって、ぐらつきを低減して安定して固定する部位である。
【００２６】
この横目地取り付け部材３０は、固定部３２の貫通孔にねじ２５が通されて、上側パネル３の裏面下端部において枠体７を介し、ねじ２５によって固定されている。このとき、横目地取り付け部３４は、上側パネル３の下端面に密接するように配置されている。ここで、固定部３２には段差が設けられているため、成形の誤差などにより横目地取付け部３４と固定部３２とで形成される形状がパネルの裏面形状と多少ずれていたとしても、段差がこの誤差を吸収し固定部３２の浮きを生じることがない。
【００２７】
また、横目地取り付け部材３０は、ゴム、プラスチック、金属など種々の材料で構成することができる。さらに、横目地取り付け部材３０は、芯材４２と、芯材４２を被覆する被覆層４３とを有することが好ましい。芯材４２には硬質の剛性材料、例えば、金属、木材、剛性の大きい硬質の樹脂やゴムなどを用いることができる。被覆層４３は芯材よりも軟質で弾力性を有する材料、例えば、種々の合成樹脂材料、エラストマー材料又は軟質ゴム材料を用いることができる。被覆層４３は、芯材に沿う形状に限定されず、種々の形状に形成された部位を備えていても良い。また、係止片３８は、芯材４２や被覆層４３とは異なる弾性を有する材料で成形されても良いが、好ましくは、被覆層４３と同じ材料から一体に成形される。芯材と被覆層とを有する横目地取り付け部材３０は、複合押出しによって得ることができる。図２，３，５に示す横目地取り付け部材３０は、金属製の芯材４２と芯材４２全体を被覆するエラストマー材料の被覆層４３とを備えている。
【００２８】
横目地取り付け部材３０は、横目地に沿って断続的に設けられる。また、横目地取り付け部材３０の横目地取り付け部３４は、横目地の縦目地との交差部分、すなわち左右のパネル３−３の側端面間に対応する位置（縦目地内）では、縦目地材２９をつたって流れ落ちる水の流路を確保するため、少なくとも部分的に欠如部分（欠除部分を含む）、すなわち存在しない部分が設けられる。また、縦目地に取り付けられる縦目地材２９が水受け部材１０の直上まで延びるようにするために、縦目地との交差部分全体に横目地取り付け部３４を設けないこともある。このような構成は、横目地取り付け部３４を所定の部位において除去することによって形成しても良い。また、横目地取付け部材３０の長さと、上側パネル３に対する取付位置とを調節し、横目地取付け部材３０の端部間に間隔をあけることによって容易に達成できる。
【００２９】
例えば、本実施形態では、横目地取り付け部材３０は、上側パネル３とほぼ同じ長さに形成されており、横目地取り付け部３４は横目地取り付け部材３０全体にわたって連続的に形成されている。１つの横目地取付け部材３０は、１枚の上側パネル３に一致するように取り付けられており、図３に示すように、横目地取り付け部３４の端部は、上側パネル３の側端面に対応する位置に配置されている。
【００３０】
横目地部材５０は、横目地を被覆するとともに水受け部材１０及び横目地取り付け部材３０の横目地取り付け部３４を外側から隠蔽する部位を備える部材である。横目地部材５０は、長尺状に形成されており、意匠部５２と脚部５４とを備えている。意匠部５２は、横目地部材５０の長手方向に沿って連続して設けられる部分で、上下方向において少なくとも上側パネル３の下端面から水受け部材１０の室外側下端までを覆うことができる幅を有する。脚部５４は、意匠部５２の裏側からほぼ直角に突出して形成されて、横目地取り付け部材３０の横目地取り付け部３４に固定される部分である。脚部５４は、横目地取り付け部３４と係合可能な形状に形成される。
【００３１】
意匠部５２の室外面は、横目地部材５０が外壁防水構造１に取り付けられた状態で、建物の外観の一部を構成する。このため、意匠部５２のパネル３，５外面との位置関係を調整したり、意匠部５２の外面に意匠を付与したりすることによって、外壁防水構造１の外観を整えることができる。例えば、意匠部５２は、外壁防水構造１に取り付けられた状態で、パネル３，５の外面とほぼ同一平面を成すように形成されても良いし、パネル３，５の外面より突出する形状に形成されても良い。あるいは、パネル３，５の外面よりくぼむように形成されても良い。
【００３２】
意匠部５２の表面に付与できる意匠は、色、模様、立体形状など種々の意匠である。例えば、パネル３，５の外面と同調する同一または類似の色を付与しても良いし、異なる色を付与しても良い。また、立体意匠としては、例えば、パネル３，５の表面に設けられるエンボス模様や縞模様とほぼ同一の模様や、レンガ調の意匠などの立体意匠、古代建築様の外観を形成できる唐草模様、レリーフなどを付与できる。
【００３３】
本実施形態の横目地部材５０は、図２，３，５に示すように、意匠部５２は、平板状に形成されており、外面は、平面に形成されている。また、パネル３，５と同様の色に形成されており、横目地部分が目立たないように形成されている。脚部５４は、意匠部５２の裏面上部から横断面において意匠部５２に対してほぼ垂直に突出する長尺板状に形成されており、横目地取り付け部３４の溝状部に挿入して固定可能な形状に形成されている。脚部５４の上下の面には、横目地取り付け部３４の係止片３８と同様の間隔で配置された係止凸部５６が形成されており、係止片３８との係合が可能で接触面積が増大された形状となっている。
【００３４】
この横目地部材５０は、その脚部５４が、外壁防水構造１に取り付けられている横目地取付け部材３０の横目地取り付け部３４に挿入されて固定される。この時、意匠部５２は、少なくとも上側パネル３の下端面から下側パネル５の上部までの範囲を隠蔽しており、横目地、横目地取付け部材３０、及び水受け部材１０が外側から視認されないように配置されている。また、意匠部５２の外面は、室内外方向においてパネル３，５と略同一平面を成している。
【００３５】
横目地部材５０は、横目地取り付け部材３０と同様、種々の材料で構成することができ、芯材５８と、芯材５８を被覆するように設けられた被覆層５９とを有することが好ましい。芯材５８には、硬質の剛性材料で、例えば、金属、木材、剛性の大きい樹脂やゴムなどを用いることができる。また、被覆層５９には、芯材よりも軟質で弾力性を有する材料で、種々の合成樹脂材料、エラストマー材料又はゴム材料を用いることができる。被覆層５９は、芯材５８に沿う形状に限定されず、種々の形状に成形された部位を備えていても良い。図２〜５の横目地部材５０は、金属製の芯材５８と、熱可塑性エラストマー材料より成り芯材５８全体を被覆する被覆層５９とを備えている。
【００３６】
横目地部材５０は、意匠部５２が横目地全体にわたって連続して視認されるように、隣接する横目地部材５０の端部どうしができるだけ近接するように取り付ける。好ましくは、横目地部材５０の長手方向の端部は、密接される。また、隣接する横目地部材５０の互いに対向する端部は、同一の横目地取り付け部材３０に固定されると、隣接する横目地部材５０の端部間の縦方向の固定位置のずれを低減することができ、好ましい。さらに、本発明に係る横目地部分の構成において、各部材の連結部分が左右方向で重なることを回避するため、横目地部材５０の端部は、縦目地部内ではなくパネル３の中間に位置することが好ましい。
【００３７】
一方、横目地部材５０の脚部５４は、横目地取付け部材３０の横目地取り付け部３４と同様、縦目地を通って流れる水の流路を確保するため、あるいは縦目地材２９を水受け部材１０の直上まで延ばすために少なくとも縦目地との交差部分において、欠如部分を備えていることが好ましい。脚部５４が存在しない部分は、予め横目地部材５０全体に脚部を設けた後、縦目地に対応する部位を除去したり、所定部位のみに脚部が設けられた形状に横目地部材５０を成形したりすることで形成できる。
【００３８】
本実施形態では、横目地部材５０は、上側パネル３の左右方向の長さより長い部材に形成されている。そして、図１に示すように、１つのパネル３の中間位置に横目地部材５０の端部が配置されている。この横目地部材５０が取り付けられているものと同一の横目地取り付け部材３０には、隣接する他の横目地部材５０の端部が、前記の横目地部材５０の端部に突き合わされた状態に配置されている。また、脚部５４は、図３に示すように、左右方向において上側パネル３の側端面に対応する位置に端部を有するように形成されている。
【００３９】
本実施形態では、図５に示すように、隣接する横目地部材５０の端部間にわたって意匠部連結部材６１が設けられている。意匠部連結部材６１は、薄板状部材で、横目地部材５０の脚部５４の先端から下面側に沿うように延びる被固定部６３と、横目地部材５０の意匠部５２の裏面に沿うコネクタ部６５とを備えている。コネクタ部６５は、図１に示すように横目地部材５０の互いに対向する端部間に配置され、端部間に隙間がある場合には室外側から視認される可能性のある部分で、その外面に、横目地部材５０の意匠部５２の表面と同様の意匠が付与されている。
【００４０】
意匠部連結部材６１は、被固定部６３が、互いに隣接する横目地部材５０の脚部５４の下面側から先端部分を覆う状態で、横目地取り付け部材３０の横目地取り付け部３４内に挿入されることによって上側パネル３に固定される。意匠部連結部材６１によって、横目地部材５０の継ぎ目が目立ちにくく、外観における意匠部５２の連続性が向上されている。また、横目地部材の継ぎ目において意匠部間に隙間が生じていても、横目地部材や水受け部材が視認されることがない。
【００４１】
横目地取付け部材または横目地部材のうち、上側パネル３の下端面により近い部材と、上側パネル３の下端面との間には、シール部６８が形成されている。シール部６８は、上側パネル３の下端面に水が接触することを防ぐ部位である。シール部６８を構成する材は、上側パネル３の下端面に直接設けられても良いし、横目地取付け部材の横目地取り付け部または横目地部材の上面に設けられても良い。
【００４２】
シール部６８は、上側パネル３により近接して設けられる横目地取り付け部材または横目地部材のいずれか一方の表面を形成しており軟質で弾力性を有する材料からなる被覆層４３によって形成されると、別部材を必要としないため、好ましい。さらに好ましくは、シール部６８は、上側パネル３の下端面への密着性や接着性が良好なシール材を備える。シール材としては、粘着テープなどのシール部材または接着剤、粘着剤などのシール用材料などを使用することができる。
【００４３】
本実施形態では、図２〜５に示すように、シール部６８は、横目地取り付け部材３０の横目地取り付け部３４の上面に設けられている。シール部６８は、接着性を有するテープ状のシール材を備えている。このシール材は、少なくとも上側パネル３の室外側近傍に設けられていれば良いが、好ましくは、本実施形態のように、上側パネル３の下端面の幅（上側パネル３の厚み）と同様の幅に形成される。
【００４４】
また、本実施形態のように横目地取り付け部３４と脚部５４との間に隙間ができる構成では、横目地取り付け部３４と脚部５４との間の隙間をシールする、すなわち横目地取り付け部３４と脚部５４との間の空間を密閉する密閉部２７が設けられることが好ましい。図２〜５に示すように、密閉部２７は、本実施形態では、独立気泡のスポンジのような弾性変形可能なシール材であり、横目地取り付け部３４と脚部５４との間に水が入り込むことを防ぐことができる。なお、密閉部２７は、横目地取付け部材３０及び／又は横目地部材５０の外面に弾力性を有する被覆層４３又は５９によって一体成形されていても良い。
【００４５】
縦目地材２９は、公知の目地材であり、コーキング剤などの湿式材料によって形成されていても良いし、ゴム、エラストマーなどの弾性材料を所定形状に成形して得られる乾式目地部材であっても良い。本実施形態では、図４に示すように、パネル３，５の側端面に圧接されて弾性変形する係止片３８を有する縦目地部材２９とした。縦目地部材２９は、係止片３８によってパネル３−３，５−５間に固定され、パネル裏側、すなわち室内側に水が浸入することを防いでいる。
【００４６】
本実施形態において横目地の上方から下方に向かって延びている縦目地部材２９の下端は、横目地の中間部分まで延びている。すなわち、横目地部材５０の脚部５４の除去されている部分を通って下方に延びている。言い換えれば、図４に示すように、縦目地部材２９は、上側パネル３の側端面に対応する縦位置に配置されている横目地部材５０の脚部５４の端部や、横目地取り付け部材３０の横目地取り付け部３４の端部といった各端部の間を通って配置されている。
【００４７】
外壁防水構造１は、予め上側パネル３の下部に横目地取り付け部材３０を取り付けておき、各パネル３，５、水受け部材１０を骨格部分９に固定した後、縦目地部材２９を固定し、横目地部材５０を取り付けることによって得ることができる。この方法で施工すると、横目地部材５０の取り付けが容易である。
【００４８】
この外壁防水構造１では、パネル３，５の表面より内側に入り込んだ水は、縦目地材をつたって水受け部材１０の上面に流れ落ち、外壁の外側まで良好に排水される。このとき、横目地を構成する下側パネル５は水受け部材１０によって、上側パネル３の下端面はシール部６８、あるいは横目地部材５０または横目地取り付け部材３０によって、水受け部材１０の上を通る水から遮断されており、水と接触することがない。また、上側パネル３の下端面は、シール部６８によって、直接外側から上側パネル３の下端面と横目地部材５０または横目地取り付け部材３０との間に入り込もうとする水が遮断されるため、水と接触することがない。
【００４９】
また、横目地に設けられる横目地取り付け部材３０の横目地取り付け部３４および横目地部材５０の脚部５４は、縦目地との交差部分に欠如部分があるため、縦目地をつたって横目地付近まで流れ落ちてきた水は、横目地の上に溜まることなく、水受け部材１０まで流れ落ちて、外壁の外側に排水される。特に、縦目地部材２９が横目地取り付け部３４及び脚部５４の端面間を通っているため、縦目地を通る水が確実に水受け部材１０の上面に誘導される。さらに、図４に示すように、縦目地部材２９の下端が縦方向における横目地取り付け部３４及び脚部５４が設けられている高さ位置よりも下方に延びていると、縦目地をつたう水がより確実に水受け部材１０の上面まで誘導される。
また、横目地部材５０は、他の部材が固定されたままの状態で取り外しできるため、施工から年数を経て、劣化などにより意匠部の交換が必要となった場合等には横目地部材５０のみを容易に交換することができる。
【００５０】
本発明の別の実施形態に係る外壁防水構造について、図６を参照して説明する。
図６の水受け部材７０は、板状の取り付け端部７２から上方に延びる止水部７３と取り付け端部７２より下方において下傾する板状に形成された被覆部７４、及び被覆部７４に対して屈曲されて下方を指向する水切り部７５とを備えている。
なお、図６において、水受け部材７０の水受け連結部材７７は、水受け部材７０の止水部７３から水切り部７５までの立体形状と同様に形成され、止水部７３の上端に係合する係合端部を備える形状とすることができる。
【００５１】
横目地取り付け部材８０は、アルミニウムなどの金属材料によって形成されており、図２に示す横目地取付け部材３０とほぼ同様の固定部８２及び横目地取り付け部８４とを備えている。横目地取付け部８４の溝状部８５の内面には、後述する横目地部材９０の脚部９２から突出する係止片９４に係合可能な係止凹部８７が所定の間隔で形成されている。
また、横目地取付け部材８０の延長部８９は、横目地部材９０の意匠部９６の裏面形状に沿って延びる形状に形成されている。
【００５２】
また、横目地部材９０は、硬質ゴムからなる芯材９８と、芯材９８の外側面を被覆し、軟質ゴムより成る被覆材料部９９とを備えている。横目地部材９０においては、芯材９８が横断面において緩やかな曲線を有する形状の意匠部９６と脚部９２とを形成しており、脚部９２からは、その裏面から上側および下側に突出し係止凹部８７に係合するリップ状の係止片９４が設けられている。
また、横目地部材９０の意匠部９６の上端には、被覆材料部と同材料から横目地部材と一体に成形されたリップ状の密閉部１００が設けられている。密閉部１００は、横目地部材９０の脚部９２と横目地取り付け部８４との間の隙間を密閉する。
【００５３】
この外壁防水構造では、水受け部材７０に、止水部７３が設けられているため、図２の止水部材１９や弾性シール材１７を必要とせず、部品点数が削減されている。また、横目地取り付け部材８０を、アルミニウムなどの金属材料によって成形することにより、強度を低下させることなく各部の厚みを薄くすることができ、横目地取り付け部８４のために必要とされる横目地の幅を低減することができる。
また、横目地取付け部材８０の延長部８９を横目地部材９０の意匠部９６の裏面形状に沿ってその下部まで延びる長さに形成することで、意匠部連結部材に兼用することができ、部品点数を削減できる。さらに、横目地部材９０の被覆材料部９９と同じ軟質ゴムで密閉部１００を形成することにより、密閉部１００を別の材料で製造する場合と比較して容易に成形することができる。また、密閉部１００を別部材で構成しないため、部品点数が削減される。また、横目地部材９０の芯材９８を硬質ゴムで成形することにより、芯材９８の材料で弾性変形可能な係止片９４を形成することができる。
【００５４】
また、レンガ調の意匠部１０３を備えている横目地部材１０１を図７に示す。意匠部１０３は、レンガの形状に突出し、レンガの色に形成されたレンガ部１０５と、レンガ部１０５よりくぼんだ線条に形成され、目地の色に形成された目地部１０７とを備えている。この横目地部材１０１では、横目地部分が、パネル１１０と同様のレンガ模様に形成されているため、レンガ造りの建物により類似する外観が得られる。すなわち、横目地部分によって、外観が低下されることが、良好に抑制されている。
なお、図７に示す横目地取付け部材１１２は、図２〜５に示す横目地取付け部材３０と同様であり、水受け部材１１４は、図６に示す水受け部材７０と同様である。
【００５５】
さらに、横目地取付け部材の横目地取り付け部と、目地部材の脚部との形状は、種々に変更することができる。例えば、横目地取り付け部を室外側に向かって突出する板状部に形成し、横目地部材の脚部を室内側に向かって開口する溝状部に形成しても良い。この形状であっても、横目地部材は、パネルや横目地取付け部材が固定されている状態において、挿入によって係合固定することができる。またこのような構成では、上側パネルの下端面をシールするシール部は、上側パネルの下端面と横目地部材の上面との間に形成される。
【００５６】
また、横目地部材と横目地取付け部材とを係合固定できる形状は、溝状部と溝状部に挿入される形状に限定されず、例えば、板状部に設けられた開孔部と開孔部を挿通して係合固定される凸状部など係合によって固定できる種々の形状とすることができる。
また、水受け部材が断続的に設けられる構成とする場合には、水受け部材が設けられない横目地部分に、公知の湿式目地材などを設けても良い。
【００５７】
【発明の効果】
本発明では、配列されたパネルを備える建物の外壁構造において、横目地部分の外観の低下が抑制され、かつパネル内部への水の浸入が抑制されているとともに排水性の良好な建物の外壁防水構造を提供することによって、水によるパネルの寿命の短縮化が抑制されるとともに、外壁の外観の低下が抑制される。また、この外壁防水構造において、横目地部分をパネルと違和感のない配置、意匠とすることで建物の外観を向上させることができる。

BACKGROUND OF THE INVENTION
The present invention relates to an outer wall structure of a building in which an outer wall is constituted by arranged panels.
[0002]
[Prior art]
In the exterior wall structure of a building that uses exterior panels, the panels are arranged vertically and horizontally to form the exterior surface, and the gap formed between the panels, that is, the joints, is provided with waterproofness and design. Wet or dry joint materials are being constructed. Among these, in the outer wall structure where dry joint material is constructed on at least one of the vertical joint and the horizontal joint, the vertical joint material constructed on the vertical joint is interrupted at the intersection of the vertical joint and the horizontal joint. There is a case where the construction of “horizontally” is made so that the horizontal joint material to be constructed is continuous. In this configuration, the water that has flowed down the vertical joint material tends to accumulate on the horizontal joint at the intersection. The accumulated water may enter the indoor side through the gap between the panel and the joint material, or may penetrate into the panel from the surface of the exterior panel having water absorption like a ceramic board or a concrete board. If water enters the inside of the panel, the board may be quickly corroded or deteriorated, or the board may be gradually destroyed by repeated volume expansion due to freezing.
In order to eliminate such problems, a dry joint member is used for the vertical joint, the upper end of the lower panel is covered from the indoor side of the panel along the horizontal joint, and the lower side of the panel is directed from the indoor side to the outdoor side. There is an outer wall structure provided with a long plate-shaped water receiving member that is inclined to the surface. In this outer wall structure, the water flowing down along the vertical joint member can be received by the water receiving member and drained to the outdoor side.
[0003]
[Problems to be solved by the invention]
However, in this configuration, a sufficient gap for water to flow must be provided between the water receiving member and the upper panel. As a result, the gap and the water receiving member can be seen from the outside of the building, which may impair the appearance. In particular, when using a panel having water absorption, in order to prevent water from seeping into the panel from the lower end surface of the upper panel, a gap between the upper and lower panels is prevented so that the lower end of the upper panel does not contact water flowing on the water receiving member. Must be larger. Therefore, the gap between the upper and lower panels is clearly visible, and the appearance of the building is likely to be impaired.
[0004]
Therefore, in the present invention, in the outer wall structure of the building including the arranged panels, the deterioration of the appearance of the horizontal joint portion is suppressed, and the penetration of water into the inside of the panel is suppressed and the drainage property of the building is good.
