【０００１】
【発明の属する技術分野】
本発明は、水密性の優れた水切り材とそれを用いた窓上又は窓下の防水構造に関する。
【０００２】
【従来の技術】
従来、実公平４−１２６７号公報に窓枠と外壁の防水構造が記載されている。上記公報記載の窓枠と外壁の防水構造は、窓枠と外壁との間に配置される水切り材と水密材とを具備したものである。
また、水切り材と外壁との間に水密材として、各種のブチルテープが貼設されている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記ブチルテープは粘着性を有しているので外壁材の位置合わせや修正に手間取る等作業性に問題があった。
【０００４】
本発明は、このような従来の水切り材に貼設される水密材の問題点に着目してなされたものであり、その目的とするところは、従来の問題点を解決し、作業性に優れ、防水性に優れた水切り材及びそれを用いた窓上の防水構造を提供することにある。
【０００５】
【課題を解決するための手段】
上記目的を達成するために、請求項１記載の発明は、屋外方向に下り勾配にされた傾斜部と、この傾斜部の屋外側端部から下方に延びる下延部と、傾斜部の屋内側端部から上方に延びる上延部とからなり、上延部の屋外面に粘着性を有する水密材と、隣接して水密材の厚みより大きくなされ、粘着性がなく、圧縮性を有する発泡体が貼設されていることを特徴とする。
【０００６】
また、請求項２記載の発明は、窓上又は窓下の防水構造において、請求項１記載の水切り材で外壁材と窓枠との間を防水したことを特徴とする。
【０００７】
（作用）
請求項１記載の本発明の水切り材においては、屋外方向に下り勾配にされた傾斜部と、この傾斜部の屋外側端部から下方に延びる下延部と、傾斜部の屋内側端部から上方に延びる上延部とからなり、上延部の屋外面に粘着性を有する水密材と、隣接して水密材の厚みより大きくなされ、粘着性がなく、圧縮性を有する発泡体が貼設されているので、外壁材を下地材にセットする際に外壁面の裏面にまず水密材より厚みの大きい発泡体に接し、粘着性を有する水密材とは接しておらず位置合わせや修正が容易である。
【０００８】
請求項２記載の本発明の窓上又は窓下の防水構造においては、請求項１記載の水切り材で外壁材の外壁材と窓枠との間を防水しているので、外壁材を下地材にリベット等で締めつけることにより外壁材と水切り材に貼設された水密材により防水性を発現する。
【０００９】
【発明の実施の形態】
次に、本発明の実施の形態を図面を参照しながら説明する。
図１と図２は本発明の一実施例であって、図１は窓上の水切り材を取り付ける状態を示す斜視図、図２は図１のＡ部を拡大して示す水切り材の断面図である。図３は本発明の窓上の防水構造の一実施例を示す断面図、図４は本発明の窓上の防水構造の別の実施例を示す断面図である。
【００１０】
本発明の水切り材６は、図１と図２に示すように、不図示の外壁材の下端部と窓上枠９及び窓縦枠７との間に配置され屋外方向に下り勾配にされた傾斜部６１と、この傾斜部６１の屋外側端部から下方に延びる下延部６３と、傾斜部の屋内側端部から不図示の外壁の裏面側で上方に延びる上延部６２とからなり、上延部６２の外壁面側に粘着性を有するブチルゴムテープの水密材６５が貼設され、隣接して水密材の厚みより大きくなされ、粘着性がなく、圧縮性を有するウレタン系発泡体６８が貼設されている。
【００１１】
また、水切り材６の傾斜部６１の裏面側にはＥＰＤＭ（エチレン−プロピレン−ジエン−ターポリマー）製の水密材６４が貼設されている。
さらに、水切り材６の上延部６２の端部側より１２ｍｍ内側に水密材６５と直交して別のブチルゴムテープの水密材６６が下地材５（スタッド）と水切り材の間に水密材６５と密着させながら貼設されるものである。
上記下地材５（スタッド）は、断面コ字形状の型鋼であって、外壁面側には発泡ポリエチレンシート５１が貼設されている。
【００１２】
窓縦枠７の上端部には窓縦枠上キャップ７１が取り付けられ、キャップの廻り及び窓上枠との段差部にブチルゴムシーラント６７が貼設されている。
【００１３】
次に、上記水切り材を使用した窓上の防水構造の施工方法について説明する。
まず、窓縦枠上キャップ７１の廻りにブチルゴムシーラント６７をセットする。そして、水切り材６に貼設された水密材６４及び６５の離型紙をはがし窓上枠９及び窓縦枠上キャップ７１にセットする。
ついで、水密材６６を水切り材６と下地材５との間に水密材６５と密着させながら貼り渡す。
【００１４】
その後、窓上外壁材（不図示）を上記水切り材６の傾斜部６１の上に載せてセットする。この際、外壁材の自重によって水切り材６が下方にさがり、傾斜部６１の裏面側の水密材６４が押しつぶされ、窓上枠９及び窓縦枠７と水切り材との間を水密にする。
この段階では外壁材と水切り材６の粘着性がなく、圧縮性を有するウレタン系発泡体６８と接し、水密材６５及び６６とは接しておらず位置合わせ等の修正が容易にできる。外壁材の位置合わせが終了した時点で窓水切りスペーサー１１を外壁材と水切り材６の間に挿入しその端面を防水する。
最後に、外壁材のフレーム（不図示）と下地材５とをリベット等で固着し、下地材５に貼設された発泡ポリエチレンシート５１及びウレタン系発泡体６８を圧縮することで外壁材と下地材との間を水密にする。
【００１５】
図３は上記の施工方法により防水構造となした窓上水切り断面の一例を示す。
図３において、硬質木片セメント板３Ａが外壁材として用いられ、外壁材下端面より上方に鉄フレーム１０が取り付けられている。水切り材６の上延部６２の上端部に水密材６５が貼設され、その下側にウレタン系の発泡体６８が貼設され、鉄フレーム１０により水密材６５及びウレタン系の発泡体６８が圧接され水密になされている。また、水切り材６の傾斜部６１の裏面側の水密材６４は窓上枠９との間を水密になされ、窓上の防水構造となされている。
【００１６】
図４は上記の施工方法により防水構造となした窓上水切り断面の他の例を示す。図４において、アルミ外壁３Ｂが外壁材として用いられ、外壁材下端面に鉄フレーム１０が取り付けられている。水切り材６の上延部６２の下側部に水密材６５が貼設され、さらにその下側にウレタン系の発泡体６８が貼設され、鉄フレーム１０により水密材６５及びウレタン系の発泡体６８が圧接され水密になされている。また、水切り材６の傾斜部６１の裏面側の水密材６４は窓上枠９との間を水密になされ、窓上の防水構造となされている。
【００１７】
（実施例の作用）
本実施例の水切り材６によると、水切り材６の上延部６２に貼設された水密材６５及び６６よりもウレタン系発泡体６８の厚みが大になされているので、外壁材３Ａ或いは３Ｂ等をセットする際には水密材６５，６６とは接しないので、位置合わせ等の修正が容易である。その後外壁材３Ａ或いは３Ｂと下地材５とをリベットで固定することにより外壁材３Ａ或いは３Ｂは下地材５へ引き寄せられ、ウレタン系発泡体６８は圧縮され、外壁材３Ａ或いは３Ｂと水密材６５，６６が粘着性を持って接した状態になり水密になされる。
【００１８】
【発明の効果】
請求項１記載の本発明の水切り材においては、屋外方向に下り勾配にされた傾斜部と、この傾斜部の屋外側端部から下方に延びる下延部と、傾斜部の屋内側端部から上方に延びる上延部とからなり、上延部の屋外面に粘着性を有する水密材と、隣接して水密材の厚みより大きくなされ、粘着性がなく、圧縮性を有する発泡体が貼設されているので、外壁材を下地材にセットする際に外壁面の裏面にまず水密材より厚みの大きい発泡体に接し、粘着性を有する水密材とは接しておらず位置合わせや修正が容易である。
