【０００４】
【発明が解決しようとする課題】
上記特許文献１記載のようなユニット建物の目地部構造は、上下階間に外壁パネルの外観意匠と異なる化粧胴差が突出して露出するので、建物の外観意匠面で問題があった。特に、タイル貼りにした外壁面材や彫りの深い模様の外壁面材によってユニット建物の高級感を演出しようとする場合、上記のような目地部構造は建物の外観意匠を大幅に損ない、大きな問題となっていた。
【０００５】
本発明の課題は、外観意匠の向上した建物の目地部構造を提供することにある。
【０００６】
【課題を解決するための手段】
請求項１記載の発明は、上下に連なる上階の外壁パネル下端部と下階の外壁パネル上端部間にパネル間目地部が形成された建物の目地部構造において、パネル間目地部の目地幅は外壁パネル内に形成されたパネル内目地部の目地幅と略同じ寸法になされ、パネル間目地部には隙間を閉塞して水密にする防水材が設けられていることを特徴とする。

【００１１】
請求項６記載の発明は、請求項５に記載の建物の目地部構造において、前記外壁パネルと継ぎ外壁パネルは、いずれも、下地板の屋外側面にタイル貼りされてなり、継ぎ外壁パネルのタイルは外壁パネルの下地板との間に架け渡され、パネル間目地部は外壁パネルのタイルと架け渡された継ぎ外壁パネルのタイルとの間に形成されていることを特徴とする。
【００１２】
請求項７記載の発明は、請求項１〜６のいずれか１項に記載の建物の目地部構造において、前記建物は、上階建物ユニットと下階建物ユニットを上下に配置して構築したユニット建物であり、上階の外壁パネルは上階建物ユニットに予め取り付けられ、下階の外壁パネルは下階建物ユニットに予め取り付けられていることを特徴とする。
【００１３】
（作用）
請求項１記載の建物の目地部構造によると、パネル間目地部の目地幅は外壁パネル内に形成されたパネル内目地部の目地幅と略同じ寸法になされているので、上階と下階との境界部が外壁パネル内と同外観となって連続し、建物の外観意匠が向上する。
また、パネル間目地部には、防水材を設けるだけであるから、目地部の部品構成が簡略化できる。
【００１４】
請求項２記載の建物の目地部構造によると、さらに、前記パネル間目地部には、屋内側への延焼を防止する防火材が設けられているので、防火性の機能を付与できる。
【００１５】
請求項３記載の建物の目地部構造によると、さらに、上階または下階の少なくともいずれか一方の外壁パネルは、下地板の屋外側面にタイル貼りされてなるので、建物の外観意匠がさらに向上する。
【００１６】
請求項４記載の建物の目地部構造によると、第１と第２のパネル間目地部の目地幅は、外壁パネル内に形成されたパネル内目地部の目地幅と略同じ寸法になされているので、上階と下階との境界部が外壁パネル内と同外観となって連続し、建物の外観意匠が向上する。
【００１７】
請求項５記載の建物の目地部構造によると、さらに、前記継ぎ外壁パネルは、上階の外壁パネルの下端部裏面側から垂下するブラケットに取着されているので、継ぎ外壁面材の取着が容易である。

請求項６記載の建物の目地部構造によると、さらに、前記外壁パネルと継ぎ外壁パネルは、いずれも、下地板の屋外側面にタイル貼りされてなるので、建物の外観意匠がさらに向上する。
そして、継ぎ外壁パネルのタイルは外壁パネルの下地板との間に架け渡され、パネル間目地部は外壁パネルのタイルと架け渡された継ぎ外壁パネルのタイルとの間に形成されているので、架け渡されたタイルによって下地板間の隙間が塞がれ、防水性と防火性が向上する。
【００１９】
請求項７記載の目地部構造によると、前記建物はユニット建物であり、上階の外壁パネルは上階建物ユニットに予め取り付けられ、下階の外壁パネルは下階建物ユニットに予め取り付けられているので、建築現場の施工工数を削減して工期を短縮できる。
【００２０】
【発明の実施の形態】
図１〜図３は、本発明の実施の形態１であって、図１はユニット建物の目地部構造を示す縦断面図、図２は図１のユニット建物を上下に分解して示す斜視図、図３は図１に示す上下階の外壁パネル正面図である。
【００２１】
（建物）
本実施の形態１における建物は、図２に示すように、上階建物ユニット３と下階建物ユニット２を上下に配置して構築したユニット建物１である。
【００２２】
上階建物ユニット３は、４本の柱３１と、柱３１の下端部間に架け渡された４本の床梁３２と、柱３１の上端部間に架け渡された４本の天井梁３３とから、直方体状の箱形に骨組みが組まれ、この上階建物ユニット３には、水平方向に並列する複数の上階の外壁パネル５，５，・・が予め工場段階で取り付けられている。外壁パネル５は、上階建物ユニット３の底面より突出しないように、床梁３２の下面よりわずかに上方に取り付けられている。
また、下階建物ユニット２は、上記と同様、４本の柱２１と、柱２１の下端部間に架け渡された４本の床梁２２と、柱２１の上端部間に架け渡された４本の天井梁２３とから、直方体状の箱形に骨組みが組まれ、この下階建物ユニット２には、水平方向に並列する複数の下階の外壁パネル４，４，・・が予め工場段階で取り付けられている。
【００２３】
上階の外壁パネル５と下階の外壁パネル４は、図１に示すように、いずれも、下地板５１，４１の屋外側面にタイル５２，４２が貼り付けられたものである。タイル５２，４２は、いずれも、矩形状であって、長辺側を水平方向に向けて縦横に配置され、上段と下段のタイルは水平方向に位置をずらし千鳥状に配列されている。このため、図３に示すように、上下のタイル間には直線状の水平なパネル内目地部７が複数列形成され、左右のタイル間には上記水平なパネル内目地部７（横目地）と千鳥状に交差する縦目地部がパネル内に形成されている。
【００２４】
（建物の目地部構造）
上記ユニット建物１の目地部構造は、図１と図３に示すように、上下に連なる上階外壁パネル５の下端部と下階外壁パネル４の上端部間に、パネル間目地部６が形成されたものである。
上記パネル間目地部６の目地幅６１は、上下階の外壁パネル４，５内に形成されたパネル内目地部７の目地幅７１と略同じ寸法になされている。
【００２５】
パネル間目地部６には、その隙間を閉塞して水密にするシリコーン樹脂等の防水材８が設けられている。また、上階の外壁パネル５の裏面側に設けられた下枠５３から柔軟な防水シート９を垂下し、この防水シート９を折り曲げその下端部をパネル間目地部６内に引き込み、下階外壁パネル４の上端面と前記防水材８との間に挟み込んでいる。
【００２６】
また、上記パネル間目地部６には、屋内側への延焼を防止する防火材１０が設けられている。この防火材１０は、火災時の熱で体積が膨張しパネル間目地部６を閉塞するようにする熱膨張性の耐火材（例えば、熱膨張性黒鉛組成物等）で形成されている。
【００２７】
なお、上階建物ユニット３の床梁３２と、下階建物ユニット２の天井梁２３との間には、気密材１２が設けられている。
また、下階の外壁パネル４の上枠４３と天井梁２３の上面との間には、湿気は通すが水は通さない壁上透湿通気テープ１１が設けられ、上下階の壁内を通気できるようにしている。
【００２８】
（本実施の形態１の作用）
本実施の形態１のユニット建物１の目地部構造によると、パネル間目地部６の目地幅６１は、外壁パネル４，５内に形成されたパネル内目地部７の目地幅７１と略同じ寸法になされているので、上階と下階との境界部が外壁パネル４，５内と同外観となって連続し、ユニット建物１の外観意匠が向上する。
また、パネル間目地部６には、防水材８と防水シート９とを設けるだけであるから、化粧胴差しを設けてパネル間目地部を覆う従来の目地部構造に比べて目地部の部品構成が簡略化できる。
【００２９】
さらに、前記パネル間目地部６には、屋内側への延焼を防止する防火材１０が設けられているので、防火性の機能を付与できる。
【００３０】
さらに、上階と下階の外壁パネル５，４は、下地板５１，４１の屋外側面にタイル５２，４２が貼り付けられたもので、上下階の境目に化粧胴差し等がなくタイル模様が連続するので、ユニット建物１の外観意匠がさらに向上する。
【００３１】
図４〜図６は、本発明の実施の形態２であって、図４はユニット建物の目地部構造を示す縦断面図、図５は図４に示す上下階の外壁パネル正面図、図６は図４の変形例であって、（イ）はユニット建物の目地部構造を示す縦断面図、（ロ）はブラケット付き下枠の断面図である。
本実施の形態２において、前記実施の形態１と本質的に同じものには同符号を付け、異なるものだけ別符号を付けて説明する。
【００３２】
（建物）
本実施の形態２における建物は、前記実施の形態１と同様、上階建物ユニット３と下階建物ユニット２を上下に配置して構築したユニット建物１である。
【００３３】
上記ユニット建物１において、前記実施の形態１と異なる点は、図４，図５に示すように、上下に連なる上階外壁パネル５の下端部と下階外壁パネル４上端部間に隙間が形成され、この隙間に外壁パネル４，５と色柄が同意匠のタイル貼りされた継ぎ外壁パネル１５が取り付けられている点である。
上階外壁パネル５は上階建物ユニット３に予め工場付けされ、下階外壁パネル４も下階建物ユニット２に予め工場付けされるが、継ぎ外壁パネル１５は建築現場で現地付けされる。
継ぎ外壁パネル１５は、下地板１５１の屋外側面に一列だけ複数のタイル１５２が水平方向に貼り付けられたものである。
【００３４】
（建物の目地構造）
本実施の形態２のユニット建物１の目地構造は、図４，図５に示すように、上階外壁パネル４の下端部と継ぎ外壁パネル１５の上端部との間に第１のパネル間目地部１６が形成され、下階外壁パネル４の上端部と継ぎ外壁パネル１５の下端部との間に第２のパネル間目地部１７が形成されたものである。
第１と第２のパネル間目地部１６，１７の目地幅１８，１８は、前記外壁パネル４，５内に形成されたパネル内目地部７の目地幅７１と略同じ寸法になされている。
【００３５】
前記継ぎ外壁パネル１５は、図４に示すように、上階外壁パネル５の下端部裏面側から垂下するブラケット１９に取着されている。ブラケット１９は、短冊状の金属製板材で形成され、その上端部が下枠５３に取り付けられ、下端部は下地板１５１の裏面側に折り曲げられて当接され、継ぎ外壁パネル１５の表面側からビス１５３を貫通させ、このビス１５３によって継ぎ外壁パネル１５をブラケット１９の下端部に固定している。
【００３６】
上記ブラケット１５の代わりに、図６に示すような、下枠本体５３１とブラケット５３２とが一体になされたブラケット付き下枠５３Ａを使用してもよい。
【００３７】
継ぎ外壁パネル１５のタイル１５２は、上端縁部が外壁パネル５の下地板５１との間に架け渡され、下端縁部が外壁パネル４の下地板４１との間に架け渡されている。
パネル間目地部１６は、上階の外壁パネル５のタイル５２と架け渡された継ぎ外壁パネル１５のタイル１５２との間に形成され、パネル間目地部１７は、下階の外壁パネル４のタイル４２と架け渡された継ぎ外壁パネル１５のタイル１５２との間に形成されている。
【００３８】
（本実施の形態の作用）
本実施の形態のユニット建物の目地部構造によると、第１と第２のパネル間目地部１６，１７の目地幅１８，１８は、外壁パネル４，５内に形成されたパネル内目地部７，７の目地幅７１，７１と略同じ寸法になされているので、上階と下階との境界部が外壁パネル４，５内と同外観となって連続し、ユニット建物１の外観意匠が向上する。
【００３９】
さらに、前記継ぎ外壁パネル１５は、上階の外壁パネル５の下端部裏面側から垂下するブラケット１９に取着されているので、継ぎ外壁面材１５の取着が容易である。
【００４０】
さらに、前記外壁パネル４，５と継ぎ外壁パネル１５は、いずれも、下地板４１，５１，１５１の屋外側面にタイル貼りされてなるので、ユニット建物１の外観意匠がさらに向上する。
そして、継ぎ外壁パネル１５のタイル１５２は、その上端縁部と下端縁部が外壁パネル４，５の下地板４１，５１との間に架け渡され、パネル間目地部１６，１７は、外壁パネル５，４のタイル５２，４２と架け渡された継ぎ外壁パネル１５のタイル１５２との間に形成されている。
このため、架け渡されたタイル１５２によって、下地板５１，１５１間の隙間と、下地板４１，１５１間の隙間とが塞がれ、防水性と防火性が向上する。
【００４１】
以上、本発明の一実施の形態を図面により詳述したが、本発明の具体的な構成はこの実施の形態に限られるものではなく、本発明の要旨を逸脱しない範囲の設計の変更等があっても本発明に含まれる。
【００４２】
【発明の効果】
請求項１記載の建物の目地部構造によると、上階と下階との境界部が外壁パネル内と同外観となって連続し、建物の外観意匠が向上する。
また、パネル間目地部には、防水材を設けるだけであるから、目地部の部品構成が簡略化できる。
【００４３】

[0039]
Furthermore, since the joint outer wall panel 15 is attached to the bracket 19 that hangs down from the rear surface of the lower end portion of the outer wall panel 5 on the upper floor, the joint outer wall member 15 can be easily attached.
[0040]
Further, since the outer wall panels 4 and 5 and the joint outer wall panel 15 are both tiled on the outdoor side surfaces of the base plates 41, 51 and 151, the external appearance design of the unit building 1 is further improved.
The upper end edge and the lower end edge of the tile 152 of the joint outer wall panel 15 are bridged between the base plates 41, 51 of the outer wall panels 4, 5, and the inter-panel joints 16, 17 are joined to the outer wall panel. It is formed between the tiles 52 and 42 of the 5 and 4 and the tile 152 of the spanning outer wall panel 15 bridged.
For this reason, the gap between the base plates 51 and 151 and the gap between the base plates 41 and 151 are closed by the bridged tile 152, and the waterproofness and fire resistance are improved.
