【０００１】
【産業上の利用分野】
本発明は、連設される壁パネルの連設面同士を密着させる接合構造に関する。
【０００２】
【従来の技術および発明が解決しようとする課題】
一般に、建物の建築工法として、柱や梁等の耐力材を軸組し、その表面に仕上げ材を取付けていく軸組工法と、複数のパネルを箱状に組合わせて各パネルに耐力を持たせるパネル工法が知られている。
【０００３】
このパネル工法においては、例えば複数の壁パネルを連設する場合、連設しようとする壁パネルの連設面に接着剤を塗布し、連設面同士を突き合わせ、さらにその連設部分をスクリュー釘を用いて連結した上で、接着剤が硬化するまで圧締治具を用いて壁パネル同士を圧締するようにしていた。
【０００４】
この場合、壁パネルの連設部分にスクリュー釘を打ち込んで連結する作業は、スクリュー釘の打ち込み本数が多数に及ぶため、手間がかかり、施工に時間がかかるという問題があった。
【０００５】
これに対して近年では、工業化の目的から、現場施工の簡略化、工期の短縮化が図られるようになっている。この工業化の推進の為に、従来のスクリュー釘の打ち込みによる壁パネルの連結に代えて、接合金物を用いて壁パネルを連結することが考えられている。
【０００６】
このような壁パネルの接合金物として、例えば、図１１に示す、いわゆる雄雌の接合金物１００が用いられる。接合金物１００は、雌接合金物１１０および雄接合金物１２０から構成され、それぞれの金物を、図１１に示すように、連設しようとする壁パネル１３０ａ，１３０ｂの連設面１３２ａ，１３２ｂに座堀１３４ａ，１３４ｂを設けて取付け、雌接合金物１１０と雄接合金物１２０とを係合させることにより壁パネル１３０ａ，１３０ｂ同士を圧締させるものである。
【０００７】
詳述すると、雄接合金物１２０は、表面中央位置に突出する係合部１２２を有している。雌接合金物１１０は、雄接合金物１２０と係合して雄接合金物１２０を引き寄せるもので、その引き寄せに必要なストロークを有する縦長のものとなっていて、雄接合金物１２０の係合部１２２を開口部１１６を介して受け入れて係止するガイド部１１２が形成されている。このガイド部１１２は、上部側で大きく突出し、そこから順に下部にかけて低くなり、雄接合金物１２０が係合当初の状態から順に下部側にいくにしたがって雌接合金物１１０が取付けられた連設面１３２ａ側に引き寄せられるようになっている。このように、ガイド部１１２は傾斜部よりなる引き寄せ部１１４を有している。
【０００８】
上述した接合金物１００を用いて、壁パネル１３０ａ，１３０ｂを直線状に連設する場合、まず、その連設面１３２ａに雌接合金物１１０が取付けられている壁パネル１３０ａを所定位置に立設固定し、その連設面１３２ａに接着剤を塗布しておく。次いで、その連設面１３２ｂに雄接合金物１２０が取付けられている壁パネル１３０ｂをクレーン等にて吊り上げ、垂下状態にして壁パネル１３０ａの連設面１３４ａに対して壁パネル１３０ｂの連設面１３４ｂを近接させ、壁パネル１３０ｂの雄接合金物１２０の係合部１２２を上方から雌接合金物１１０の開口部１１６内に係入させる。そして、壁パネル１３０ｂを徐々に降ろしていくと、雌接合金物１１０のガイド部１１２が有する引き寄せ部１１４に沿って雄接合金物１２０が雌接合金物１１０が取付けられた連設面１３２ａ側に引き寄せられ、雄接合金物１２０の係合部１２２がガイド部１２２の下端に達し係止された状態で壁パネル１３０ａの連設面１３２ａと壁パネル１３０ｂの連設面１３２ｂとが圧締された状態となる。
【０００９】
また一方、工業化をさらに促進し、現場作業のより簡略化および精度向上を図ることにより工期の短縮によるコスト削減および品質向上を達成する目的で、予め工場等で壁パネル本体にサイディングを取付けて一体化形成した、いわゆるサイディング付き壁パネルが用いられるようになってきた。このようなサイディング付き壁パネルを直線上に連設する場合、サイディングの成形誤差および壁パネル本体への取付け誤差等によりサイディング間に隙間が生じたり、サイディングの連設側端部同士がぶつかって傷ついたり等の接合不良が生じるおそれがある。そこで、このような接合不良を防止するために、連設される一方のサイディング付き壁パネルのサイディングの連設側端部および他方のサイディング付き壁パネルのサイディングの連設側端部にパネルの厚さ方向に互いに重ね合わせ可能な突起状の薄肉部をそれぞれ設け、サイディング付き壁パネルを壁パネル本体の連設面同士を突き合わせて連設する際に、サイディングにおいては、それぞれの薄肉部を厚さ方向に重ね合わせて接合することが考えられる。
【００１０】
そしてさらに、サイディング付き壁パネルの接合部の防水性を確保するために、薄肉部間に防水シール材を設けることが考えられる。薄肉部間に防水シール材を設けるためには、サイディング付き壁パネルが連設される前に、サイディング付き壁パネルのいずれか一方のサイディングの薄肉部に予め防水シール材を設けておき、サイディング付き壁パネルが連設されて、薄肉部が重ね合わされることによりその防水シール材を挟み込むことが必要となる。
【００１１】
しかしながら、従来の接合金物１００を用いて、上述したようなサイディング付き壁パネルの連設を行おうとする場合、所定位置に立設固定された一方のサイディング付き壁パネルに対して、他方のサイディング付き壁パネルが上方より下方へ移動することにより引き寄せられて密着することとなるので、それぞれのサイディング付き壁パネルのサイディングの肉薄部間に挟み込まれた防水シール材がすり切れて破損するおそれが生じるという問題点が起こる。防水シール材が破損するとサイディング付き壁パネルの接合部の防水性が低下し、好ましくない。
【００１２】
本発明は上記問題点に鑑みなされたものであり、その目的は、連設される壁パネルがその厚さ方向に重ね合わされる他部材を有する場合でも、その部材を破損することなく、壁パネルの連設面同士を密着させることができる壁パネルの接合構造を提供することにある。
【００１３】
【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、連設される一方の壁パネルの連設面に取付けられる雌接合金物と、他方の壁パネルの前記雌接合金物と対応する連設面に取付けられる雄接合金物と、を含み、前記雄接合金物と前記雌接合金物とが係合することにより、連設される壁パネルの連設面同士を密着させる壁パネルの接合構造において、
前記壁パネルは、芯材を枠組みした枠体の建屋内方側の面に面材、建屋外方側の面に仕上げ材を有し、
前記雌接合金物は、上部及び下部の取付け座と、開口部を有したガイド部とを有する縦長状とされ、
前記ガイド部は、上部から下部に向かって前記雄接合金物の導入部、前記雄接合金物を引き寄せる引き寄せ部、前記雄接合金物が有する係合部を係止する係止部を有し、前記開口部を介して前記係合部を係止位置まで導き、
前記開口部は、前記仕上げ材側への前記雄接合金物の変位を許容するクリアランスを含み、
前記クリアランスは、前記導入部から前記係止部における前記係合部の係止位置直前までの開口部が前記雌接合金物の縦軸中心に対して前記面材側の縁部までの距離よりも前記仕上げ材側の縁部までの距離が大きく設定され、
前記雌接合金物を取り付ける一方の壁パネルの連設面に、前記雌接合金物を挿入可能で、かつ、前記雌接合金物の上部に前記雄接合金物挿入用の空間を有する縦長の座堀を設け、この縦長の座堀内の上下部に前記雌接合金物の上下部の取付け座にそれぞれ対応した大きさの座堀を設けてこれら上下部の座堀に前記上下部の取付け座を挿入固着すると共に、
前記雄接合金物を取り付ける他方の壁パネルの連設面に、前記雌接合金物取付け用の縦長の座堀及び上下部の座堀と同様の座堀を設け、前記雄接合金物が有する取付け座を前記下部の座堀に挿入固着することを特徴としている。
【００１５】
請求項２記載の発明は、請求項１において、前記開口部の縁部には、前記雄接合金物を前記係止位置へ導くテーパー部が設けられていることを特徴としている。
【００１７】
【作用】
請求項１記載の発明にあっては、雌接合金物が、開口部を有し、その開口部を介して前記雄接合金物が有する係合部を係止位置まで導くガイド部を有し、開口部が連設面方向への雄接合金物の変位を許容するクリアランスを含むことにより、雄接合金物は、クリアランスの分だけ連設面方向へ変位した状態で開口部に係入され、そのまま案内部によって係止位置まで導かれることができる。よって、壁パネルが連設される際に、雄接合金物が取付けられた他方の壁パネルは、雌接合金物が取付けられた一方の壁パネルに対して、連設面方向へ変位した状態で一方の壁パネルと近接して下方へ移動し、雄接合金物が係止位置に導かれるのに伴い、他方の壁パネルも一方の壁パネルと合致する方向へ動き、連設面同士が密着される。
【００１８】
したがって、連設される壁パネルが、その接合に際して連設面方向に重ね合わされる部材を有する場合でも、その部材を破損することなく、壁パネルの連設面同士を密着させることができる。
【００１９】
また、連設される仕上げ材付き壁パネルが、互いの仕上げ材が重ね合わされて接合する部材を有する場合に有用である。
【００２０】
請求項２記載の発明にあっては、開口部の縁部には、前記雄接合金物を前記係止位置へ導くテーパー部が設けられていることにより、雄接合金物はテーパー部によって係止位置に導かれ、雌接合金物と雄接合金物との係合が完了する。この雄接合金物の動きに伴い、雄接合金物が取付けられた他方の壁パネルも連設される一方の壁パネルと合致する方向へ動き、連設面同士が密着される。
【００２１】
よって、作業者が意図的に連設面同士を合わせる必要はなく、雄接合金物の係合部を雌接合金物の案内部に開口部を介して係入し、後は他方の壁パネルを下方へ移動していくのみで自動的に他方の壁パネルは連設面方向へ変位した位置から移動し、連設面同士が合致するので、連設作業は容易で、作業性がよい。
【００２３】
【実施例】
以下、本発明の好適な実施例について図面に基づいて詳細に説明する。
【００２４】
図１は、本実施例に係る壁パネルの接合金物１０およびその壁パネルへの取付け構造を示す分解斜視図である。
【００２５】
本実施例に係る接合金物１０は、図１に示すように、雌接合金物２０および雄接合金物３０とから構成されており、パネルの幅方向に直線状に連設しようとする一方の壁パネル８０ａの連設面８２ａに雌接合金物２０を、他方の壁パネル８０ｂの連設面８２ｂに雄接合金物３０をそれぞれ取付けて、雌接合金物２０と雄接合金物３０とを係合させることにより壁パネル８０ａ，８０ｂ同士を圧締させるものである。
【００２６】
ここで、壁パネル８０ａとは、図１に示すように、芯材を方形状に枠組みした枠体の建屋内方側の面に面材８１ａを取付けて形成された壁パネル本体と、壁パネル本体の建屋外方側の面を覆って取付けられた防水シート８６ａと、防水シート８６ａを介して壁パネル本体の建屋外方側の面を覆って取り付けられたサイディング７０ａとを含み構成され、これらの構成部材が予め工場等で一体化形成されて現場に搬送される、いわゆる仕上げ材付きのパネルである。サイディング７０ａは、壁パネル本体に釘にて取付け固定されるものであるが、この釘が打ち込まれる場所のサイディング７０ａと防水シート８６ａとの間には、例えば、ブチルゴム等の第１のシール材８９ａが設けられていて、釘によって穴があいた防水シート８６ａの隙間から雨等が浸入し、壁パネル８０ａの防水性が低下するのを防いでいる。
【００２７】
壁パネル８０ｂは、壁パネル８０ａと同様の部材であるので、その説明は省略し、以下、壁パネル８０ｂの構成部材で壁パネル８０ａの構成部材と同様の部材については、同符号を用い、末尾にｂをつけて記すこととする。
【００２８】
壁パネル８０ａの、壁パネル８０ｂとの連設面８２ａである壁パネル本体の端面には、その建物外方側に切欠き部８８が設けられており、この切欠き部８８内には、例えば、合成樹脂、合成ゴム等の第２のシール材９０が組み込まれ固着されている。第２のシール材９０は、壁パネル８０ａと壁パネル８０ｂとが連設された状態で、連設面８２ａと連設面８２ｂとの間に挟まれて、壁パネル８０ａ，８０ｂとの接合部の防水性を確保する。
【００２９】
壁パネル８０ａのサイディング７０ａは、図１に示すように、その幅方向の壁パネル７０ｂ側の端部に第１の薄肉部７２を有し、壁パネル８０ｂのサイディング７０ｂは、その幅方向の壁パネル８０ａ側の端部に第２の薄肉部７４を有する。第１の薄肉部７２および第２の薄肉部７４は、壁パネル８０ａと壁パネル８０ｂとの連設時には、パネルの厚さ方向に重なり合って納まるように形成されており、連設時の重なり合った状態で、第１の薄肉部７２は建物内方側に、第２の薄肉部７４は建物外方側に配置される。
【００３０】
第１の薄肉部７２の、第２の薄肉部７４との重合面７６には、例えば、合成樹脂、合成ゴム等の第３のシール材９２が設けられている。第３のシール材９２は、壁パネル８０ａと壁パネル８０ｂとが連設された状態で、第１に薄肉部７２と第２の薄肉部７４との間に挟まれて、壁パネル８０ａ，８０ｂとの接合部の防水性を確保する。
【００３１】
すなわち、壁パネル８０ａ，８０ｂの接合部は、第３のシール材９２（１次防水）および第２のシール材９０（２次防水）による２次防水構造となっていて、高い防水性が確保されることとなる。
【００３２】
図２（Ａ）は、壁パネルの接合金物１０を構成する雌接合金物２０を、同図（Ｂ）は、雄接合金物３０を示す斜視図である。また、図３（Ａ）は、壁パネル８０ｂの連設面８２ｂに、座堀り６０ｂを設けて取付けられた雄接合金物３０を示す正面図、同図（Ｂ）は縦断面図であり、図４（Ａ）は、壁パネル８０ａの連設面８２ａに、座堀り６０ａを設けて取付けられた雌接合金物２０を示す正面図、同図（Ｂ）は縦断面図である。さらに、図５は、雄接合金物３０と雌接合金物２０とが係合した状態を示す断面図である。
【００３３】
壁パネル８０ｂの連設面８２ｂに取付けられる雄接合金物３０は、図２（Ｂ）に示すように、円盤状の取付け座３２の表面中央位置よりガイドロッド３４を突出させ、このガイドロッド３４の先端に膨出状の係合部３６が設けられている。なお、円盤状の取付け座３２には、ビス止め用の取付け穴３８が複数、本実施例においては２個形成されている。
【００３４】
壁パネル８０ａの連設面８２ａに取付けられる雌接合金物２０は、雄接合金物３０と係合して雄接合金物３０を引き寄せるもので、図２（Ａ）に示すように、その引き寄せに必要なストロークを有する縦長のものとなっている。また、この雌接合金物２０は、上部および下部に取付け座２２、２４が形成され、上部の取付け座２２には１個、下部の取付け座２４には２個のねじ止め用の取付け穴２６がそれぞれ形成されている。さらに、上部および下部の取付け座２２，２４間には雄接合金物３０の係合部３６を受入れて係止する縦長のガイド部４０が形成されている。
【００３５】
ガイド部４０は、図４（Ｂ）に示すように、上部の取付け座２２より突出し、さらに下部の取付け座２４に向かって傾斜する形状となっている。また、ガイド部４０には縦長の開口部４２が形成され、開口部４２は、その上部において、雄接合金物３０の係合部３６を挿入し得るように大きく形成され、下部側は、雄接合金物３０の係合部３６が脱落しないようにガイドロッド３４の直径にほぼ相応し、かつ若干のクリアランスを有した大きさに形成されている。このクリアランスは、雌接合金物２０と雄接合金物３０との係合時に、雄接合金物３０のサイディング７０ａ側への変位を許容するものである。
【００３６】
ガイド部４０は、図４（Ｂ）に示すように、その上部から下部に向かって導入部５０、引き寄せ部５２および係止部５８とを有する。
【００３７】
導入部５０は、ガイド部４０の上部に位置し、ガイド部４０の上端から引き寄せ部５２の上端までいたる垂下部を含む部分であり、その上方から雄接合金物３０の係合部３６を開口部４２に係入して引き寄せ部５２まで導く。
【００３８】
引き寄せ部５２は、ガイド部４０の中間部に位置し、導入部５０の下端から係止部５８の上端までいたる傾斜部よりなり、雄接合金物３０の係合部３６が傾斜部の開口部４２に沿って移動することにより、雄接合金物３０を雌接合金物２０側へ引き寄せる部分である。引き寄せ部５２は、図４（Ｂ）に示すように、傾斜の異なる２つの傾斜部、すなわち、上方に位置する第１引き寄せ部５４および下方に位置する第２引き寄せ部５６よりなる。
【００３９】
第１引き寄せ部５４は第２引き寄せ部５６と比して、垂下方向に対する傾斜がゆるやかに形成されている。すなわち、第１引き寄せ部５４は第２引き寄せ部５６と比して、雄接合金物３０の係合部３６の垂下方向への単位移動距離に対して水平方向への移動距離が大きく形成されていて、言い換えれば、第１の引き寄せ部５４は、第２の引き寄せ部５６と比して垂下方向に対する角度が大きく形成されているものである。
【００４０】
係止部５８は、ガイド部４０の下端部に位置し、引き寄せ部５２の下端からガイド部４０の下端までいたる垂下部よりなり、雄接合金物３０の係合部３６が係止される部分である。開口部４２に係入された雄接合金物３０の係合部３６は、図５に示すように、係止部５８に係止されて雌接合金物２０と雄接合金物３０との係合が完了し、壁パネル８０ａと壁パネル８０ｂは圧締される。
【００４１】
次に、開口部４２が有するクリアランスについて説明する。
【００４２】
クリアランスは、下部側の開口部４２が、図４（Ａ）に示すように、雌接合金物２０の縦軸中心線Ａ₁ に対して、面材８１ａ側の縁部４６までの距離Ｌ₁ よりもサイディング７０ａ側の縁部４８までの距離Ｌ₂ が大きく設定されていることにより形成されている。縦軸中心線Ａ₁ は、図５に示すように、雄接合金物２０が雌接合金物３０に係止された状態で、その係止位置の中心点を通るもので、すなわち、雄接合金物３０が、雌接合金物２０のガイド部４０の下端において係止された状態で、壁パネル８０ａの連設面８２ａと壁パネル８０ｂの連設面８２ｂとが合致するように配置されている。
【００４３】
ガイド部４０の開口部４２のサイディング７０ａ側の縁部４８は、開口部４２の下部において、係止位置方向へ傾斜するテーパー部４９を有しており、雄接合金物３０は、このテーパー部４９により、スムーズに係止位置へ導かれる。
【００４４】
上述した構成の雌接合金物２０および雄接合金物３０は、連設する一方の壁パネル８０ａの連設面８２ａおよび他方の壁パネル８０ｂの連設面８２ｂにそれぞれ取付けられるものであるが、その取付け構造について説明する。
【００４５】
雌接合金物２０を取付ける壁パネル８０ａの連設面８２ａには、図１および図４（Ａ）に示すように、雌接合金物２０の取付け座２２，２４を挿入可能な縦長の座堀６０ａを設けている。また、この縦長の座堀６０ａ内の下部位置に雌接合金物２０の下部の取付け座２４に対応した座堀６２ａを設け、かつ縦長の座堀６０ａの上部位置に雌接合金物２０の上部の取付け座２２に対応した大きさの座堀６４ａを設けるようにしている。
【００４６】
そして、雌接合金物２０の下部の取付け座２４を一方の壁パネル８０ａの連設面８２ａに形成した下部側の座堀６２ａに挿入固着し、かつ上部の取付け座２２を上部側の座堀６４ａに挿入固着するようにしている。なお、縦長の座堀６０ａは雄接合金物３０の挿入に支障がないように雌接合金物の上部に空間を有する大きさに設定されている。
【００４７】
同様にして、雄接合金物３０を取付ける他方の壁パネル８０ｂの連設面８２ｂに、図１および図３（Ａ）に示すように、上述した座堀６０ａ，６２ａ，６４ａと同様の座堀６０ｂ，６２ｂ，６４ｂを設け、雄接合金物３０の取付け座３２を下部側の座堀６２ｂに挿入固着するようにしている。
【００４８】
次に、本実施例に係る接合金物１０を用いて、壁パネル８０ａ，８０ｂを連設する施工方法および接合金物１０の作用について述べる。
【００４９】
図６に示すように、壁パネル８０ａ，８０ｂをパネルの幅方向に直線状に連設する場合、先に立設固定する壁パネル８０ａの側端面である連設面８２ａには、上下方向に亘って、所定間隔をあけて複数（本実施例においては３カ所）の座堀６０ａが形成してあり、この座堀６０ａ内に形成した上部および下部の座堀６４ａ，６２ａに雌接合金物２０がそれぞれ挿入固着されている。
【００５０】
また、壁パネル８０ａの後に建て付ける壁パネル８０ｂの対向側端面である連設面８２ｂには壁パネル８０ａの座堀６０ａと対応する位置に座堀６０ｂがそれぞれ形成され、かつ座堀６０ｂ内に形成した下部の座堀６２内に雄接合金物３０がそれぞれ挿入固着されている。
【００５１】
この状態において、まず壁パネル８０ａを床パネル７８上に立設固定し、その連設面８２ａに接着剤を塗布しておく。
【００５２】
次いで、壁パネル８０ｂをクレーン等にて吊り上げ、垂下状態にして壁パネル８０ａの連設面８２ａに対して壁パネル８０ｂの連設面８２ｂを近接させ、壁パネル８０ｂの雄接合金物３０の係合部３６を上方から雌接合金物２０の開口部４２内に係入する。
【００５３】
そして、壁パネル８０ｂを徐々に降ろしていくと、雄接合金物３０の係合部３６は、雌接合金物２０の開口部４２に沿って、まず導入部５０を下方へ移動し、次いで、図７に示すように、第１引き寄せ部５４および第２引き寄せ部５６を移動するにしたがい、雄接合金物３０が雌接合金物２０側に引き寄せられ、雄接合金物３０の係合部３６が係止部５８の達した状態で、壁パネル８０ａの連設面８２ａと壁パネル８０ｂの連設面８２ｂとが圧締された状態となる。従って、接着剤が硬化するまでの圧締を自動的に行うことができる。
【００５４】
なお、壁パネル８０ａ，８０ｂの連設作業に際し、雌接合金物２０と雄接合金物３０との係合および壁パネル８０ａと壁パネル８０ｂとの天端合わせを、例えば、図１０に示すような押圧治具１５０を用いて行うことができる。
【００５５】
押圧治具１５０は、図１０に示すように、被係止部１５２、押圧部１５４および握り部１５８を有する軸部１５６含み構成された治具である。押圧治具１５０は、壁パネル８０ａの壁パネル本体８４ａを構成している横芯材１７０ａに形成された第１の穴１６０および縦芯材１７２ａに形成された第２の穴１６２を利用して壁パネル８０ａに係止され、被係止部１５２に回転可能に支持された軸部１５６を握り部１５８を利用して矢印方向に回転させることにより押圧部１５４によって壁パネル８０ｂの天端を押圧するものである。
【００５６】
図８は、本実施例に係る接合金物１０を用いて壁パネル８０ａ，８０ｂを連設する場合に雌接合金物２０と雄接合金物３０とを係合させて壁パネル８０ａ，８０ｂを組立てるのに要する力と、従来の接合金物１００を用いて壁パネル８０ａ，８０ｂを連設する場合に要する力を測定して比較したグラフを示す図である。ここで、従来の接合金物１００とは、従来例で述べた図１１に示す接合金物１００である。
【００５７】
図８から明らかであるように、本実施例に係る接合金物１０によれば、壁パネル８０ａの連設面８２ａと壁パネル８０ｂの連設面８２ｂとを密着させて圧締するに際して、比較的小さな力で雌接合金物２０と雄接合金物３０を係合させることができ、大変作業性がよい。また、大きな力がかかることにより、壁パネル８０ａ，８０ｂの連設面８２ａ、８２ｂに挟まれる第２のシール材９０が破損して接合部の防水性が低下するのを確実に防止することができる。
【００５８】
詳述すると、本実施例に係る接合金物１０によれば、雌接合金物２０が有する引き寄せ部５２が、傾斜の異なる第１引き寄せ部５４および第２引き寄せ部５６よりなり、上側に位置する第１引き寄せ部５４が、下側に位置する第２引き寄せ部５６と比して雄接合金物３０の係合部３６の垂下方向への単位移動距離に対して水平方向への移動距離が大きく形成されている。このことにより、壁パネル８０ａの連設面８２ａと壁パネル８０ｂの連設面８２ｂとを密着させて圧締するに際して、壁パネル８０ａ，８０ｂ同士の摩擦抵抗が比較的小さい引き寄せ部５２の上方において、垂下方向に対する傾斜がゆるやかな第１引き寄せ部５４により、それほど大きな力を要せず、壁パネル８０ｂを壁パネル８０ａ側へ引き寄せておくことができ、摩擦抵抗が大きくなる引き寄せ部５２の下方においては、第１引き寄せ部５４よりも垂下方向に対する傾斜が急で、より垂下状態に近く形成された第２引き寄せ部５６により、比較的小さな力で雄接合金物３０との係合を行うことができる。
【００５９】
よって、単一の傾斜で引き寄せ部１１４が形成された雌接合金物１１０より構成される従来の接合金物１００と比して、引き寄せ部５２の上方において要する力は若干大きいものの、引き寄せ部５２の下方において要する力は２／３程度ですむ。
【００６０】
次に、雌接合金物２０および雄接合金物３０の係合時における雄接合金物３０の連設面方向における動きおよびその作用について説明する。
【００６１】
雌接合金物２０のガイド部４０は、上述したように、その開口部４２が雄接合金物３０のガイドロッド３４の直径に相応し、かつ若干のクリアランスを有して形成されている。
【００６２】
雄接合金物３０の係合部３６は、雌接合金物２０の開口部４２内に係入される際に、壁パネル８０ａが、図１および図９（Ａ）に示すように、サイディング７０ａの第１の薄肉部７２の重合面７６に第３のシール材９２を備えていることにより、より抵抗の少ないサイディング７０ａ側へ変位し、開口部４２のサイディング７０ａ側の縁部４８にガイドロッド３４を接触させた状態で開口部４２内に係入される。そして、そのままの状態で、雄接合金物３０の係合部３６は開口部４２に沿って下方へ移動していく。
【００６３】

[Industrial application fields]
The present invention is a bonding method in which the continuous surfaces of the wall panels to be provided are in close contact with each other. Construction About.
[0002]
[Background Art and Problems to be Solved by the Invention]
Generally, as a building construction method for buildings, a shaft construction method in which load-bearing materials such as columns and beams are assembled and a finishing material is attached to the surface, and a plurality of panels are combined in a box shape to give each panel strength. Panel construction methods are known.
[0003]
In this panel construction method, for example, when connecting a plurality of wall panels, an adhesive is applied to the connecting surfaces of the wall panels to be connected, the connecting surfaces are butted together, and the connecting portions are screw nails. Then, the wall panels are clamped together using a clamping jig until the adhesive is cured.
[0004]
In this case, the operation of driving and connecting the screw nails to the continuous portion of the wall panel has a problem that the number of screw nails to be driven reaches a large number of times, which is troublesome and takes time for construction.
[0005]
On the other hand, in recent years, on-site construction has been simplified and the construction period has been shortened for the purpose of industrialization. In order to promote this industrialization, it is considered that the wall panels are connected using metal fittings instead of the conventional connection of the wall panels by driving a screw nail.
[0006]
For example, a so-called male / female joint metal 100 shown in FIG. 11 is used as such a wall panel joint metal. The metal joint 100 is composed of a female metal joint 110 and a male metal joint 120. As shown in FIG. 11, each metal hardware is formed on the connecting surfaces 132a and 132b of the wall panels 130a and 130b to be connected. 134a and 134b are provided and attached, and the wall panels 130a and 130b are pressed together by engaging the female joint hardware 110 and the male joint hardware 120.
[0007]
More specifically, the male joint hardware 120 has an engagement portion 122 that protrudes to the center position on the surface. The female joint hardware 110 engages with the male joint hardware 120 and draws the male joint metal 120, and is a vertically long one having a stroke necessary for the pulling. A guide portion 112 that is received and locked through the opening 116 is formed. The guide portion 112 protrudes greatly on the upper side and becomes lower in order from there to the lower portion, and the connecting surface 132a to which the female joint hardware 110 is attached as the male joint hardware 120 goes to the lower side in order from the initial state of engagement. It is designed to be drawn to the side. Thus, the guide part 112 has the drawing part 114 which consists of an inclination part.
[0008]
When the wall panels 130a and 130b are connected in a straight line by using the above-described joint hardware 100, first, the wall panel 130a on which the female joint hardware 110 is attached to the continuous surface 132a is erected and fixed at a predetermined position. Then, an adhesive is applied to the continuous surface 132a. Next, the wall panel 130b on which the male joint hardware 120 is attached to the continuous surface 132b is lifted by a crane or the like, and is suspended to the continuous surface 134a of the wall panel 130b with respect to the continuous surface 134a of the wall panel 130a. And the engagement portion 122 of the male joint hardware 120 of the wall panel 130b is engaged into the opening 116 of the female joint hardware 110 from above. Then, when the wall panel 130b is gradually lowered, the male joint hardware 120 is drawn toward the connecting surface 132a side to which the female joint hardware 110 is attached along the pulling portion 114 of the guide portion 112 of the female joint hardware 110. The connecting surface 132a of the wall panel 130a and the connecting surface 132b of the wall panel 130b are pressed together in a state where the engaging portion 122 of the male joint hardware 120 reaches the lower end of the guide portion 122 and is locked. .
[0009]
On the other hand, with the aim of further promoting industrialization and achieving cost reduction and quality improvement by shortening the construction period by further simplifying and improving the accuracy of on-site work, a siding is attached to the wall panel body in advance at the factory, etc. The so-called siding wall panels that have been formed have come to be used. When such wall panels with siding are arranged in a straight line, a gap is created between the sidings due to molding errors in the siding and mounting errors to the wall panel body, etc. There is a risk that bonding failure such as cracking will occur. Therefore, in order to prevent such a joint failure, the thickness of the panel is added to the siding continuous side end of one siding wall panel and the siding continuous side end of the other siding wall panel. Protruding thin wall parts that can be superposed on each other in the vertical direction are provided, and when the wall panel with siding is connected with the continuous surfaces of the wall panel body facing each other, each thin part is thickened in siding. It is conceivable to overlap and join in the direction.
[0010]
Further, in order to ensure the waterproof property of the joint portion of the wall panel with siding, it is conceivable to provide a waterproof seal material between the thin portions. In order to provide a waterproof sealing material between the thin-walled parts, before the wall panel with siding is continuously provided, a waterproof sealing material is provided in advance on the thin-walled part of one of the siding wall panels, and the siding is attached. It is necessary to sandwich the waterproof seal material by connecting the wall panels and overlapping the thin portions.
[0011]
However, when using the conventional metal joint 100 to connect the above-mentioned wall panels with siding as described above, the one with the other siding is attached to one wall panel with siding standingly fixed at a predetermined position. As the wall panel moves from the upper side to the lower side, it will be attracted and brought into close contact, so that the waterproof sealing material sandwiched between the thin parts of the siding of each wall panel with siding may be worn out and damaged. Problems arise. If the waterproof sealing material is damaged, the waterproof property of the joint portion of the wall panel with siding is lowered, which is not preferable.
[0012]
The present invention has been made in view of the above-described problems, and the object thereof is to provide a wall panel without damaging the member even when the wall panel to be provided has another member superimposed in the thickness direction. Of wall panels that can bring together the continuous surfaces Construction Is to provide.
