Description

【０００１】
【発明の属する技術分野】
本発明は、目地溝をシールする目地材に関する。
【０００２】
【従来の技術】
特開２００１−１２３６３３号公報には、目地溝の底部に、ジョイナー受けを固定し、ジョイナー受けに目地ジョイナーを取り付けるとともに目地ジョイナーに設けた充填部にシーリング材を充填して、目地カバーの圧入部でシーリング材を押圧して、目地ジョイナーから目地溝の空間に流れ出たシーリング材と、シール片とで目地溝をシールする構成が開示されている。
【０００３】
【発明が解決しようとする課題】
しかし、上述の公報に開示の技術では、ジョイナー受けは目地溝の長手方向に沿って目地溝の底部に連続して設けているので、目地溝が一方及び他方の部材をねじ止めしているねじ連結部を底部としている場合に、目地溝の底部にねじがあるため連結ねじを回避できないという問題がある。
そこで、本発明は、一方の部材と他方の部材とのねじ連結部を底部とした目地溝がある場合に、ねじを避けて目地材の取り付けができる目地材の提供を目的とする。
【０００４】
【課題を解決するための手段】
請求項１に記載の発明は、一方の部材と他方の部材のねじ連結部を底部とする目地溝に取り付けるものであり、ピ−ス材であって目地溝の底部に接着するジョイナー受けと、ジョイナー受けより長尺でシーリング材の充填部及びシール片を有してジョイナー受けに嵌合する目地ジョイナーと、目地ジョイナーと略同一長さで充填部への圧入部及びシール片を有する目地カバーとを備え、圧入部の押圧により充填部から流出したシーリング材と、シール片とで目地溝をシールするとともに、ジョイナー受けを目地溝のねじを避けた位置に取り付けることを特徴とする。
【０００５】
この請求項１に記載の発明では、一方の部材と他方の部材とをねじで連結した部分に目地溝があり、この目地溝の底部にジョイナー受けを接着する。ジョイナー受けは、目地溝の長手方向の任意の位置に取り付けでき、ジョイナー受けを互いに間隔をあけて、目地溝内のねじを避けた位置に固定する。
また、ジョイナー受けは目地ジョイナーの長さよりも短いので、運搬や施工時に取り扱い易い。更に、溝底の長手方向に目地ジョイナーの長さに合わせて固定する必要がなく任意の位置に固定すればよいので、施工作業が容易である。
次に、ジョイナー受けに目地ジョイナーを嵌合し、目地ジョイナーの内側にある充填部にシーリング材を挿入した後、目地カバーの圧入部でシーリング材を押圧しつつ、目地カバーを目地ジョイナーに嵌合する。これにより、目地溝は充填部から目地溝の空間内に流出したシーリング材と、目地ジョイナーのシール片と、目地カバーのシール片とで三重のシールをしており、水密性が高い。
【０００６】
【発明の実施の形態】
以下に、添付図面を参照して、本発明の実施の形態を詳細に説明する。図１は本発明の実施の形態にかかる目地材を部分的に示す分解斜視図であり、図２は目地材の横断面図である。
本実施の形態は、一方の部材３と、他方の部材５と、目地材７とで構成されており、一方の部材３と他方の部材５とのねじ連結部が目地溝９になっており、この目地溝９に目地材７を設けている。本実施の形態では、一方の部材３はサッシ下枠であり、他方の部材５は水切り材であり、一方の部材３と他方の部材５とはねじ８により連結されている。
目地材７は、目地溝９の底部１１側から順にジョイナー受け１３と、目地ジョイナー１５と、目地カバー１７とを備えており、目地ジョイナー１５の内側にはシーリング材１９が充填さる。シーリング材１９は、流動性のある不定形シール材であり、本実施の形態では非硬化型シリコーン材を用いている。この非硬化型シリコーン材は振動や温度変化にも優れた性能を保持し、いつまでも常に柔らかい状態で目地を充填することができる。
ジョイナー受け１３は、目地ジョイナー１５よりも短尺であり、目地溝９に沿って設け目地溝９の底部１１に固定されている。このジョイナー受け１３は底部２１の裏面に両面テープが貼られている。底部２１には目地ジョイナー１５側に目地ジョイナー１５との被嵌合部２３、２３が設けられている。被嵌合部２３、２３は、互いに向き合う方向に弾性変形して目地ジョイナー１５に嵌合可能である。
目地ジョイナー１５は、ジョイナー受け１３よりも長尺であり、本実施の形態では目地溝の長さと略同じである。この目地ジョイナー１５は、ジョイナー受け１３側に嵌合部２５、２５を備え、目地カバー１７側にシーリング材１９の充填部２７及びシール片２９、２９が設けられている。嵌合部２５はジョイナー受け１３の被嵌合部２３の外側に嵌め込まれて嵌合するようになっている。目地ジョイナー１５の充填部２７及び嵌合部２５は硬質樹脂材でできており、シール片２９、２９は軟質樹脂でできている。これらの硬質樹脂及び軟質樹脂は共にＰＶＣ（ポリ塩化ビニル）である。
充填部２７には、目地溝９の側壁３１に対面する部分にシーリング材１９の流出孔３３が形成されており、充填部２７に挿入されたシーリング材１９が側壁３１、３１側に流出可能になっており、シーリング材が充填部２７から目地溝の空間２０に移動して目地溝２７をシールするようになっている。
充填部２７の外側において、流出孔３３の目地カバー１７側には、目地溝９の側壁３１、３１に当接するシール片２９、２９が突設してあり、これらのシール片２９、２９は、それぞれ目地溝９の側壁３１に当接して流出孔３３から目地溝９内の空間２０に流出したシーリング材１９が目地カバー１７側に流れるのを堰き止めている。
充填部２７の目地カバー１７側には係止部３９が設けられており、目地カバー１７に係合するようになっている。
目地カバー１７は、充填部２７内のシーリング材１９を押圧する圧入部３７と目地溝９の開口部で一方の部材３と他方の部材５とに当接して目地溝９を覆うシール片３５、３５とを備えている。目地カバー１７は圧入部３７が硬質樹脂材でできており、シール片３５、３５は軟質樹脂でできている。これらの硬質樹脂及び軟質樹脂は共にＰＶＣ（ポリ塩化ビニル）である。
圧入部３７は、その体積で目地ジョイナー１５の充填部２７内のシーリング材１９を充填部２７から溢れ出させるものであり、充填部２７内に圧入されてシーリング材１９を流出孔３３から充填部２７外側に流出させることにより、目地溝９の側壁３１、３１と充填部２７との間にシーリング材１９を充填している。尚、圧入部３７には、ステンレス製の芯材３４が埋設されており、圧入部３７の強度を保持している。
目地カバー１７のシール片３５、３５は、目地溝９の開口付近で一方の部材３及び他方の部材５に当接して、目地溝９を塞いでいる。また、目地カバー１７には、目地ジョイナー１５の充填部２７に設けられた係止部３９と係合する係合部４１が設けられており、係止部３９と係合部４１との係合により目地カバー１７が目地ジョイナー１５に装着されている。
【０００７】
次に、本実施の形態にかかる目地材７の施工方法を説明する。一方の部材３と他方の部材５とをねじ８で連結する。このねじ連結した部分が目地溝９を形成している。
次に、目地溝９の底部１１にジョイナー受け１３を両面テープで接着する。ジョイナー受け１３は、目地溝９の長手方向に、互いに隣合うジョイナー受け１３が互いに間隔をあけて配置し、ねじ８を避けて取り付ける。ジョイナー受け１３は目地溝９に対して短尺であるから取り扱い易く、且つ任意の位置に固定することができる。即ち、底部１１の長手方向の全体に固定する必要がなく、部分的に固定すればよい。
次に、ジョイナー受け１３に目地ジョイナー１５を装着する。目地ジョイナー１５の装着は、目地ジョイナー１５に設けた嵌合部２５をジョイナー受け１３の被嵌合部２３に弾性変形により装着する。
目地ジョイナー１５をジョイナー受け１３に装着後、目地ジョイナー１５の内側にある充填部２７にシーリング材１９を充填し、目地カバー１７を目地ジョイナー１５に装着する。目地カバー１７の装着は、目地カバーの圧入部３７を充填部２７内に圧入し、目地カバー１７の係合部４１が充填部２７の係止部４０に係合することによりおこなう。充填部２７内のシーリング材１９は、圧入部３７が充填部２７に挿入されると流出孔３３から充填部２７の外側に一部が流出し、目地ジョイナー１５と目地溝９の側壁３１との間を埋める。尚、目地ジョイナー１５の外側に流出されたシーリング材１９は、目地ジョイナー１５の外側に設けられたシール片２９、２９により目地溝９の空間２０内に保持される。
目地溝９は、シーリング材１９と目地ジョイナー１５のシール片２９、２９と、目地カバー１７のシール片３５、３５とで三重のシールをしており、高い水密性を得ることができる。
また、目地溝９にあるねじ８を避けてジョイナー受け１３を取り付けることができる。
【０００８】
本発明は、上述した実施の形態に限らず、本発明の要旨を逸脱しない範囲で種々変形可能である。
例えば、一方の部材３がサッシの下枠であり、他方の部材５が水切り材であることに限らず、隣あう壁面パネルを一方の部材３及び他方の部材５とし、これらのねじ連結部を目地溝９とした場合等であってもよい。
ジョイナー受け１３は、目地溝９の長手方向にいくつ配置してもよく、ねじの数に応じて目地溝の長手方向にねじを避けて４つまたは５つ配置するものであってもよい。
【０００９】
【発明の効果】
請求項１に記載の発明によれば、一方の部材と他方の部材とのねじ連結部に目地溝がある場合に、ジョイナー受けは目地ジョイナーの長さよりも短いので、目地溝の底部に連結ねじを避けた位置で取り付けできる。
ジョイナー受けは目地ジョイナーの長さよりも短いので、運搬や施工時に取り扱い易い。更に、溝底の長手方向に目地ジョイナーの長さに合わせて固定する必要がなく任意の位置に固定すればよいので、施工作業が容易である。
