【発明の属する技術分野】
この出願の発明は、乾式目地ジョイナーに関するものである。さらに詳しくは、この出願の発明は、挿入施工時に外装材相互の接合部に円滑に挿入することができ、かつ、挿入施工後の防水性、意匠性も優れた乾式目地ジョイナーに関するものである。
【0002】
【従来の技術】
従来、住宅等の建物においては、例えば、図5に例示したように、外壁材等の外装材(ア)、(ア)相互の接合部(イ)に乾式目地ジョイナー(ウ)を挿入施工していた。
【0003】
また、上記乾式目地ジョイナー(ウ)は、対向する垂直板(エ)、(エ)を底板部(オ)に立設して嵌着溝(カ)を形成してなるベース目地材(キ)と、該ベース目地材(キ)の嵌着溝(カ)に嵌入する凸条(ク)を長尺板状のシール部(ケ)に垂設してなるトップ目地材(コ)とからなり、挿入施工に際しては、外装材(ア)、(ア)相互の接合部(イ)底部にベース目地材(キ)の底板部(オ)を配設し、該ベース目地材(キ)の嵌着溝(カ)にトップ目地材(コ)の凸条(ク)を強制的に嵌入することによって、外装材(ア)、(ア)の木口面(サ)、(サ)間にシール部(ケ)を挿入施工し、トップ目地材(コ)のシール部(ケ)によって、外装材(ア)、(ア)相互の接合部(イ)への雨水の侵入を防止していた。
【0004】
【発明が解決しようとする課題】
しかしながら、図5に例示したような従来の乾式目地ジョイナー(ウ)においては、挿入施工時に外装材(ア)の木口面(サ)とトップ目地材(コ)のシール部(ケ)との摩擦が大きいため、外装材(ア)、(ア)の木口面(サ)、(サ)間にシール部(ケ)を円滑に挿入することができないという問題があり、かつ、長尺板状のシール部(ケ)によって雨水の侵入を防止しているため、外装材(ア)の木口面(サ)とシール部(ケ)との接触面積が小さく、挿入施工後の防水性の点でも満足すべきものであるとは云い難く、また、防水性を高めるために外装材(ア)、(ア)の木口面(サ)、(サ)間にシール部(ケ)を強制的に挿入した時に、長尺板状のシール部(ケ)表面が断面U字状に湾曲するため、外観が悪くなり、挿入施工後の意匠性の点でも問題があった。
【0005】
この出願の発明は、以上の通りの事情に鑑みてなされたものであり、挿入施工時に外装材相互の接合部に円滑に挿入することができ、かつ、挿入施工後の防水性、意匠性も優れた乾式目地ジョイナーを提供することを目的としている。
【0006】
【課題を解決するための手段】
この出願の発明は、上記の課題を解決するためになされたものであって、第1の発明は、対向する垂直板を底板部に立設して嵌着溝を形成してなるベース目地材と、該ベース目地材の嵌着溝に嵌入する凸条を筒形中空状のシール部に垂設すると共に、シール部のシール面にシリコン系被覆層を形成し、かつ、シール部の下端部を目地幅に合わせて肉厚に形成してなるトップ目地材とからなることを特徴とする乾式目地ジョイナーを提供する。
【0007】
また、第2の発明は、挿入施工時にシール部が外装材の表面側端部を覆うように変形自在な筒形中空状に形成してなる前記いずれかの乾式目地ジョイナーを、第3の発明は、下端部が挿入施工時の挿入深さに合致するように外装材の木口面と当接するシール部のシール面にシリコン系被覆層を形成してなる前記いずれかの乾式目地ジョイナーを、第4の発明は、シール部の内周面部に目地幅に合わせて変形させる折曲用溝を形成してなる前記いずれかの乾式目地ジョイナーを、第5の発明は、筒形中空状のシール部を、長手方向全長にわたる1本の空洞を設け、かつ、空洞の底部に補強用柱体を立設して形成してなる前記いずれかの乾式目地ジョイナーを、第6の発明は、補強用柱体の頂部を、空洞の内周面部と分離して立設してなる前記の乾式目地ジョイナーを提供する。
【0008】
【発明の実施の形態】
この出願の発明は、上記の通りの特徴をもつものであるが、以下、その実施の形態について説明する。
【0009】
図1は、この出願の発明の一実施例を例示した断面図である。
【0010】
図1に示したように、この出願の発明の乾式目地ジョイナー(1)は、ベース目地材(2)とトップ目地材(3)とからなる。ベース目地材(2)は、例えば、目地幅(W)に合わせて対向する垂直板(21)、(21)を底板部(22)の中央部に立設して嵌着溝(23)を形成することによって、硬度70°程度の硬質塩化ビニル樹脂等の硬質合成樹脂よりなるベース目地材本体を形成し、さらに必要に応じて、該ベース目地材本体の各垂直板(21)、(21)の外側の底板部(22)表面の側端縁部内方および側端縁部の全長にわたって硬度90°程度の軟質塩化ビニル樹脂等の軟質合成樹脂よりなる防水突起(24)および防水舌片(25)を突設してなる長尺体よりなるものである。トップ目地材(3)は、例えば、上記ベース目地材(2)の嵌着溝(23)に弾性を利用して強制的に嵌入する凸条(31)を筒形中空状のシール部(32)に垂設することによって、硬度70°程度のEPDM(Ethylene−Propylene−Diene−Methylene rubber :エチレン・プロピレン共重合ゴム)等の弾性材料よりなるトップ目地材本体を形成すると共に、シール部(32)のシール面〔後述する図2に示す外装材(4)の木口面(41)に当接する面〕にシリコン系樹脂を被着することによって、硬度70°程度のシリコン系被覆層(33)を形成してなる長尺体よりなるものである。なお、筒形中空状のシール部(32)を形成する場合には、例えば、長手方向全長にわたる複数本の空洞(321)〔図1においては、左右両側に2本の空洞(321)、(321)〕を設けて筒形中空状のシール部(32)を形成しても良いし、1本の空洞を設けて筒形中空状のシール部を形成しても良い。ただし、1本の空洞を設けて筒形中空状のシール部を形成する場合には、例えば、空洞がつぶれたり、へこんだりするのを防止するために、後述する図4に示したように空洞(321)の底部に補強用柱体(7)を立設したり、空洞の内周面部、周壁内部等に補強材を設けたりして適度な剛性を付与するのが好ましい。また、シール部(32)のシール面にシリコン系被覆層(33)を形成する場合には、例えば、シール部(32)のシール面から表面にわたってシリコン系被覆層(33)を形成し、かつ、シリコン系被覆層(33)に所望のイメージ色の着色を施すと、目地部の外観を向上させることができるので好ましい。また、シール部(32)の基部にグラスファイバー等よりなる芯材(34)を全長にわたって埋設すると、シール部(32)の防水性を保持しつつ適度な剛性を付与することができるので好ましい。
【0011】
図2は、上記この出願の発明の一実施例の挿入施工状態を例示した断面図であり、(a)は挿入施工開始時の状態、(b)は挿入施工後の状態、(c)は挿入施工経年後の状態を示している。
【0012】
図2に示したように、この出願の発明の乾式目地ジョイナー(1)は、挿入施工に際して、外装材(4)、(4)相互の接合部(5)底部にベース目地材(2)の底板部(22)を配設し、一方の外装材(4)の木口面(41)を一方の垂直板(21)の外側面に当接して取り付けた後、ベース目地材(2)の嵌着溝(23)にトップ目地材(3)の凸条(31)を所望の深さまで強制的に嵌入することによって、シール部(32)を強制的に挿入し〔図2(a)〕、次いで、該トップ目地材(3)のシール部(32)のシール面に他方の外装材(4)の木口面(41)を当接、押圧することによって、挿入施工を完了する〔図2(b)〕。ただし、上記挿入施工に際して、隣り合う両方の外装材(4)、(4)をベース目地材(2)の垂直板(21)、(21)の外側面に当接して取り付けた後、ベース目地材(2)の嵌着溝(23)にトップ目地材(3)の凸条(31)を強制的に嵌入することによって、外装材(4)、(4)の木口面(41)、(41)間にシール部(32)を強制的に挿入して挿入施工を行っても良い。
【0013】
以上の通り、この出願の発明の乾式目地ジョイナー(1)においては、挿入施工時に外装材(4)の木口面(41)と当接するシール部(32)のシール面に摩擦の少ないシリコン系被覆層(33)を形成しているので、外装材(4)、(4)の木口面(41)、(41)間にシール部(32)を円滑に挿入することができ、従って、挿入施工時に外装材(4)、(4)相互の接合部(5)に円滑に挿入することができ、また、シール部(32)が筒形中空状であるので、挿入施工した時に、図2(b)に示したように変形して外装材(4)の木口面(41)に当接するため、外装材(4)の木口面(41)とシール部(32)との接触面積が大きくなり、優れた防水性を発揮する。また、図1に示したように、ベース目地材(2)の底板部(22)表面に防水突起(24)および防水舌片(25)を突設した場合には、図2(b)に示したように、上記シール部(32)の防水性による一次防水に加えて、防水突起(24)が外装材(4)裏面に当接密着すると共に、防水舌片(25)が変形して外装材(4)裏面に押圧密着することによって、二次防水が行える。また、図2(a)、(b)に示したように、ベース目地材(2)の底板部(22)を配設する下地面に、透湿防水シート、防水テープ等の防水材料(6)を張設した場合には、該防水材料(6)による防水性によって三次防水が行える。また、図2(b)に示したように、挿入施工直後における外装材(4)、(4)相互の接合部(5)の目地幅(W)は通常10mm程度であるが、図2(c)に示すように、挿入施工経年後(例えば、10年後)における外装材(4)、(4)相互の接合部(5)の目地幅(W)は15mm程度に拡大する。しかしながら、シール部(32)がかかる拡大に追従して変形するため、挿入施工経年後においても防水性が損われるおそれがない。また、挿入施工した時に、シール部(32)が図2(b)に示すように変形してシール部(32)表面が略平面状になるため、外観が損われるおそれもなく、挿入施工後の意匠性も優れている。
【0014】
また、図1に示したように、点線の範囲内にあるトップ目地材(3)のシール部(32)の下端部(322)を目地幅(W)に合わせて肉厚に形成した場合には、図2(b)に例示したように、シール部(32)の下端部(322)を外装材(4)、(4)相互の接合部(5)に正確に位置決めして挿入することができる。
【0015】
また、図2(b)に示したように、挿入施工時にシール部(32)が外装材(4)の表面側に僅かに突出して表面側端部(42)を覆うように変形自在な筒形中空状に形成した場合には、外装材(4)の木口面(41)がシール部(32)によって完全に隠ぺいされるため、外装材(4)の表面側端部(42)に木口面(41)が露出して外観が損われるおそれがない。
【0016】
また、図2(b)に示したように、下端部(331)が挿入施工時の挿入深さに合致するようにシリコン系被覆層(33)を形成した場合には、シリコン系被覆層(33)の下端部(331)を、挿入深さを把握する起算点用目印にして挿入することができるため、簡単、正確に挿入することができる。
【0017】
図3は、この出願の発明の異った実施例を例示した断面図である。
【0018】
図3に示したように、トップ目地材(3)の筒形中空状のシール部(32)の空洞(321)の内周面部全長にわたって、図2(b)に示した目地幅(W)に合わせて変形させる折曲誘導用の折曲用溝(323)を複数個〔図3においては、各空洞(321)の内周面上下部に2個〕形成した場合には、図2(b)に示したようにシール部(32)を挿入施工する際に、折曲用溝(323)を折れ点にして円滑に折曲変形させて挿入することができ、特に、図1と同様にして、シール部(32)の下端部(322)を図2(b)に示した目地幅(W)に合わせて肉厚に形成すると共に、図3に示したようにシール部(32)の内周面部に目地幅(W)に合わせて変形させる折曲用溝(323)を形成した場合には、目地幅(W)に合わせて形成したシール部(32)の肉厚の下端部(322)および折曲用溝(323)の相乗作用によって、シール部(32)を目地幅(W)に合わせて正確に位置決めしつつ円滑に変形させて均密に挿入することができる。
【0019】
図4は、この出願の発明のさらに異った実施例を例示した断面図である。
【0020】
図4に示したように、トップ目地材(3)の筒形中空状のシール部(32)を形成するに際して、長手方向全長にわたる1本の空洞(321)を設け、かつ、空洞(321)の底部、好ましくは、凸条(31)に対応する底部中央の長手方向全長にわたって、連続的または断続的に補強用柱体(7)を突設して筒形中空状のシール部(32)を形成した場合には、図2(b)に示したようにシール部(32)を挿入施工する際に、空洞(321)がつぶれたり、へこんだりするのを防止し、適度な剛性を付与して円滑に挿入施工することができ、挿入施工後の外観を良好に保つことができる。
【0021】
また、図4に示したように、補強用柱体(7)を立設するに際して、補強用柱体(7)の頂部と空洞(321)の内周面部との間に間隙(8)を設けたり〔または間隙(8)を設けずに分断したり〕することによって、補強用柱体(7)の頂部を、空洞(321)の内周面部と分離して立設した場合には、図2(b)に示したようにシール部(32)を挿入施工する際に、補強用柱体(7)の補強効果、すなわち、空洞(321)のつぶれ防止効果、へこみ防止効果を損うことなく、補強用柱体(7)の頂部が柔軟に追従、移動してさらに円滑に挿入施工することができる。
【0022】
勿論、この出願の発明は、以上の実施形態によって限定されるものではなく、ベース目地材、トップ目地材等の形状、大きさ、材質等の細部については、様々な態様が可能であることは云うまでもない。
【0023】
そこで、以下に実施例を示し、この出願の発明についてさらに詳しく説明する。
【0024】
【実施例】
図1に示した乾式目地ジョイナー(1)を使用し、図2(b)に示したように、トップ目地材(3)のシール部(32)で一次防水し、ベース目地材(2)の防水突起(24)および防水舌片(25)で二次防水し、防水材料(6)で三次防水して防水性能を測定したところ、表1のような結果が得られた。

上記の結果から明らかなように、風速15、20m/sの強風下においても、外装材(4)裏面に水のにじみ出しが認められる程度の防水性を発揮し、風速30、40、50m/sの台風並みの条件下において、水の流れ出しが認められる程度であり、勿論、何れの風圧においても、防水材料(6)(防水シート)裏面には漏水は全く認められなかった。
【0026】
