Description

【０００１】
【発明の属する技術分野】
本発明は、１本の鉛直木材（柱）側面に水平木材（梁）の端面が突合され、両者が相対的に変位不可能に固定されるよう、両木材の間に介在する接合金具に関するものである。
【０００２】
【従来の技術】
木造住宅の柱・梁等の接合に関しては、従来、ホゾ加工が使用され、一般に金具は殆ど使用されなかった。しかし、これでは接合強度が不足しがちで、ホゾの加工にかなりの手間を要するという問題があった。そこで、ボルト・ナットなどの金具を初めとする各種金具が開発され、ホゾと併用する方法がよく行われるようになっている。
【０００３】
また、木材の接合作業の一層の簡略化と時間の短縮のため、近年はホゾの省略と共に、それに適合した、プレート状金具とピン、ボルトなどを含む各種接合金具が提案されている。
【０００４】
図８はその一例であって、薄い鋼板のプレス加工によってコの字状に形成されており、水平木材２０の端部に形成された２条の溝Ｍに差し込み可能で、かつ上辺に切り欠き６１，６１及びピンＰ挿入用の挿入孔６２，６２が設けられた、相対する平行な差込部分Ｉ，Ｉと、鉛直木材１０の側面にボルト・ナットＢＮで固定される接合部分Ｊと、よりなる。
このような接合金具は、あたかも鉄骨の接合のように工場にて予め加工された木材同士の接合が可能であるため、広く使用されるようになっている。
【０００５】
しかし、これらのプレート状金具とピン、ボルトなどを含む各種接合金具には、（１）鉛直木材１０に取付けられた状態では損傷し易い、
（２）鉛直木材１０への取り付けに手間と時間がかかる、
（３）鉛直木材１０へ接合金具が装着されたままでは輸送は困難である、といった問題点がある。
【０００６】
本発明者は、こうした問題を解決するための接合金具を発明し、先に出願した（特願２００１−２７４９６５）。
この先に出願した接合金具は、水平木材に結合される差込部分と、その差込部分の一端に垂直に一体結合され、鉛直木材の側面に相対向する面を有する板状接合部分と、鉛直木材の側面に予め固定される平板状の接合具と、を備えており、板状接合部分が、接合具に対して位置決めされたあと、鉛直木材の側面に対して平行に移動されることによって、接合具への接合がほぼワンタッチで行われるように構成されている。
【０００７】
従って、構造が簡単で、接合が容易であり、また施工現場での木材同士の接合作業時間を著しく短縮することができ、上記した問題点を全て解決することができる。
【０００８】
【発明が解決しようとする課題】
しかしながら、上記した接合金具を使用して、鉛直木材の相対向する二つの側面に水平木材を取付けることができるものの、同一高さにおける三つの側面あるいは四つの側面に水平木材を取付けることはできない。
木造住宅においては、こうした三つあるいは四つの側面に水平木材を取付ける必要が多々あるが、この接合金具ではこうした必要性に応じることができない。
【０００９】
そこで、本発明の目的とするところは、鉛直木材の同一高さにおける三つの側面あるいは四つの側面に水平木材を取付けることができる接合金具を提供することにある。
【００１０】
【課題を解決するための手段】
上記の目的を達成するために、本発明の請求項１に記載の接合金具は、一本の鉛直木材（１０）の同一高さにおける側面に水平木材（２０）の端面が突き合わされ、両者が相対的に変位不可能に固定されるよう、両木材間に介在する接合金具であって、前記鉛直木材（１０）の側面に突き合わされる水平木材（２０）に対応してそれぞれ取付けられ、該突き合わされる水平木材（２０）の端面に形成された縦溝（Ｍ）に差し込まれると共に孔（６２）を有し、水平木材（２０）の側面から挿通されるピン（Ｐ）がその孔（６２）に貫通することによって水平木材（２０）と結合される差込部分（Ｉ）と、その差込部分（Ｉ）の一端に垂直に一体結合され、前記鉛直木材（１０）の前記側面に相対向する面を有する板状接合部分（Ｊ）とからなる部材と、及び、前記鉛直木材（１０）の前記側面に予め固定される接合具（Ｋ）と、を備えており、前記差込部分（Ｉ）は、前記水平木材（２０）に斜めに挿入組付けされる円筒部分（４６）の外周面に鉛直板（４５）が結合されたもので、前記板状接合部分（Ｊ）は、前記接合具（Ｋ）に対して位置決めされたあと、鉛直木材（１０）の側面に対して平行に移動されることによって、接合具（Ｋ）への接合が略ワンタッチで行われるように構成され、前記接合具（Ｋ）が、鉛直木材（１０）の第一の側面（１１）から相対向する第三の側面（１３）に、少なくとも上下に二本挿通する大径軸部（３１ａ）の両端部に第一頭部（３２ａ）を設けた複数の第一棒金具（３０ａ）と、第一の側面（１１）に隣接する第二の側面（１２）から相対向する第四の側面（１４）に、前記第一棒金具（３０ａ）と同一高さにおいて、前記大径軸部（３１ａ）を貫いて、少なくとも上下に二本挿通する小径軸部（３１ｂ）の両端部に第二頭部（３２ｂ）を設けた複数の第二棒金具（３０ｂ）とで構成され、前記板状接合部分（Ｊ）は、前記第一頭部（３２ａ）及び第二頭部（３２ｂ）を水平方向に挿通可能で、その挿通によって前記位置決めを行う孔（４０）を有してなることを特徴とする。

【００１２】
さらに、請求項３に記載の接合金具は、一本の鉛直木材（１０）の同一高さにおける側面に水平木材（２０）の端面が突き合わされ、両者が相対的に変位不可能に固定されるよう、両木材間に介在する接合金具であって、前記鉛直木材（１０）の側面に突き合わされる水平木材（２０）に対応してそれぞれ取付けられ、該突き合わされる水平木材（２０）の端面に形成された縦溝（Ｍ）に差し込まれると共に孔（６２）を有し、水平木材（２０）の側面から挿通されるピン（Ｐ）がその孔（６２）に貫通することによって水平木材（２０）と結合される差込部分（Ｉ）と、その差込部分（Ｉ）の一端に垂直に一体結合され、前記鉛直木材（１０）の前記側面に相対向する面を有する板状接合部分（Ｊ）とからなる部材と、及び、前記鉛直木材（１０）の前記側面に予め固定される接合具（Ｋ）と、を備えており、その板状接合部分（Ｊ）が、前記接合具（Ｋ）に対して位置決めされたあと、鉛直木材（１０）の側面に対して平行に移動されることによって、接合具（Ｋ）への接合が略ワンタッチで行われるように構成され、前記接合具（Ｋ）が、鉛直木材（１０）の第一の側面（１１）および第三の側面（１３）に組付く一対の第一補強板（２３３ａ）間を、少なくとも上下に二本挿通する軸部（２３１）の両端部に第一頭部（２３２ａ）を設けた第一金具（２３０ａ）と、第二の側面（１２）および第四の側面（１４）に組付く一対の第二補強板（２３３ｂ）間を、前記軸部（２３１）と高低差を設けて、少なくとも上下に二本挿通する連結棒（２３４）で連結し、当該第二補強板（２３３ｂ）外面の前記第一頭部（２３１ａ）と同一高さ部分に第二頭部（２３２ｂ）を固着した第二金具（２３０ｂ）とで構成され、前記板状接合部分（Ｊ）は、前記第一頭部（２３２ａ）及び第二頭部（２３２ｂ）を水平方向に挿通可能で、その挿通によって前記位置決めを行う孔（１４０）を有してなることを特徴とする。
【００１３】
またさらに、請求項４に記載の接合金具は、一本の鉛直木材（１０）の同一高さにおける側面に水平木材（２０）の端面が突き合わされ、両者が相対的に変位不可能に固定されるよう、両木材間に介在する接合金具であって、前記鉛直木材（１０）の側面に突き合わされる水平木材（２０）に対応してそれぞれ取付けられ、該突き合わされる水平木材（２０）の端面に形成された縦溝（Ｍ）に差し込まれると共に孔（６２）を有し、水平木材（２０）の側面から挿通されるピン（Ｐ）がその孔（６２）に貫通することによって水平木材（２０）と結合される差込部分（Ｉ）と、その差込部分（Ｉ）の一端に垂直に一体結合され、前記鉛直木材（１０）の前記側面に相対向する面を有する板状接合部分（Ｊ）とからなる部材と、及び、前記鉛直木材（１０）の前記側面に予め固定される接合具（Ｋ）と、を備えており、その板状接合部分（Ｊ）が、前記接合具（Ｋ）に対して位置決めされたあと、鉛直木材（１０）の側面に対して平行に移動されることによって、接合具（Ｋ）への接合が略ワンタッチで行われるように構成され、前記接合具（Ｋ）が、鉛直木材（１０）の第一の側面（１１）および第三の側面（１３）に組付く一対の第一補強板（３３３ａ）間を、少なくとも上下に二本挿通する第一軸部（３３１ａ）の両端部に第一頭部（３３２ａ）を設けた第一金具（３３０ａ）と、第二の側面（１２）および第四の側面（１４）に組付く一対の第二補強板（３３３ｂ）間に、前記第一軸部（３３１ａ）と高低差を設けて、少なくとも上下に二本挿通する第二軸部（３３１ｂ）の両端部に第二頭部（３３２ｂ）を設けた第二金具（３３０ｂ）とで構成され、前記板状接合部分（Ｊ）は、少なくとも上下に四つ形成された孔（１４０ａ，１４０ｂ，１４０ｃ，１４０ｄ）を有し、前記第一の側面（１１）および第三の側面（１３）側では前記上から第１孔（１４０ａ）と第３孔（１４０ｃ）に前記第一頭部（３３２ａ）を，前記第二の側面（１２）および第四の側面（１４）側では第２孔（１４０ｂ）と第４孔（１４０ｄ）に前記第二頭部（３３２ｂ）を，それぞれ水平方向に挿通可能でその挿通によって前記位置決めを行うようにしたことを特徴とする。
【００１４】
なお、カッコ内の記号は図面および後述する発明の実施の形態に記載された対応要素または対応事項を示す。
【００１５】
本発明の請求項１に記載の接合金具によれば、接合具が、鉛直木材の第一の側面から相対向する第三の側面に、少なくとも上下に二本挿通する大径軸部の両端部に第一頭部を設けた複数の第一棒金具と、第一の側面に隣接する第二の側面から相対向する第四の側面に、前記第一棒金具と同一高さにおいて、前記大径軸部を貫いて、少なくとも上下に二本挿通する小径軸部の両端部に第二頭部を設けた複数の第二棒金具とで構成されているので、鉛直木材の同一高さにおける三つの側面あるいは四つの側面のそれぞれに水平木材を取付けることができる。
【００１６】
また、請求項２に記載の発明によれば、接合具が、鉛直木材の第一の側面から相対向する第三の側面に、少なくとも上下に二本挿通する大径軸部の両端部に第一頭部を設けた複数の第一棒金具と、第一の側面に隣接する第二の側面から相対向する第四の側面に、前記第一棒金具と同一高さにおいて、前記大径軸部を貫いて、少なくとも上下に二本挿通する小径軸部の両端部に第二頭部を設けた複数の第二棒金具と、前記第一棒金具および第二棒金具の第一頭部および第二頭部と鉛直木材との間に設けられた複数の補強板と、で構成されているので、同様に、鉛直木材の同一高さにおける三つの側面あるいは四つの側面のそれぞれに水平木材を取付けることができる。
【００１７】
さらに、請求項３に記載の発明によれば、接合具が、鉛直木材の第一の側面および第三の側面に組付く一対の第一補強板間を、少なくとも上下に二本挿通する第一軸部の両端部に第一頭部を設けた第一金具と、第二の側面および第四の側面に組付く一対の第二補強板間を、前記第一軸部と高低差を設けて、少なくとも上下に二本挿通する連結棒で連結し、該第二補強板外面の前記第一頭部と同一高さ部分に第二頭部を設けた第二金具と、で構成されているので、請求項１および２に記載の発明と同じく、鉛直木材の同一高さにおける三つの側面あるいは四つの側面のそれぞれに水平木材を取付けることができる。
【００１８】
またさらに、請求項４に記載の発明によれば、接合具が、鉛直木材の第一の側面および第三の側面に組付く一対の第一補強板間を、少なくとも上下に二本挿通する第一軸部の両端部に第一頭部を設けた第一金具と、第二の側面および第四の側面に組付く一対の第二補強板間に、前記第一軸部と高低差を設けて、少なくとも上下に二本挿通する第二軸部の両端部に第二頭部を設けた第二金具とで構成され、板状接合部分は、少なくとも上下に四つ形成された孔を有し、第一の側面および第三の側面側では前記上から第１孔と第３孔に前記第一頭部を，前記第二の側面および第四の側面側では第２孔と第４孔に前記第二頭部を，それぞれ水平方向に挿通可能でその挿通によって前記位置決めを行うようにしたので、同様に、鉛直木材の同一高さにおける三つの側面あるいは四つの側面のそれぞれに水平木材を取付けることができる。
【００１９】
【発明の実施の形態】
図１乃至図３を参照して、本発明の第一実施形態に係る接合金具について説明する。図１は接合金具を使用して鉛直木材１０に水平木材２０を取付ける状態を示す斜視図である。図２は接合金具の接合具Ｋを示すもので、（ａ）は正面図、（ｂ）側面図、（ｃ）は大径軸部３２ａと小径軸部３２ｂとの組付きを示す斜視図である。図３は接合の手順を示す斜視図である。
【００２０】
本発明の第一実施形態に係る接合金具は、一本の鉛直木材１０の同一高さにおける三つの側面のそれぞれに水平木材２０の端面が突き合わされ、両者が相対的に変位不可能に固定されるよう、両木材間に介在するものであり、差込部分Ｉ、板状接合部分Ｊおよび接合具Ｋを備える。
【００２１】
差込部分Ｉは、水平木材２０の端面に形成された縦溝Ｍに差し込まれると共に孔６２を有し、水平木材２０の側面から挿通されるピンＰがその孔６２に貫通することによって水平木材２０と結合される。板状接合部分Ｊは、差込部分Ｉの一端に垂直に一体結合され、鉛直木材１０の側面に相対向する面を有する。接合具Ｋは、板状接合部分Ｊと、鉛直木材１０の側面に予め固定される。また、板状接合部分Ｊが、接合具Ｋに対して位置決めされたあと、鉛直木材１０の側面に対して平行に移動されることによって、接合具Ｋへの接合が略ワンタッチで行われるように構成されている。
【００２２】
そして、当該接合金具の特徴は、接合具Ｋが、鉛直木材１０の第一の側面１１から相対向する第三の側面１３に、左右両側において、上下に挿通するパイプ製の大径軸部３１ａの両端部に第一頭部３２ａを設けた四本の第一棒金具３０ａと、第一の側面１１に隣接する第二の側面１２から相対向する第四の側面１４に、前記第一棒金具３０ａと同一高さにおいて、前記大径軸部３１ａを貫いて、左側と右側に上下に挿通する小径軸部３１ｂの両端部に第二頭部３２ｂを設けた四本の第二棒金具３０ｂとで構成されていることである。
【００２３】
小径軸部３１ｂを大径軸部３１ａに貫通させることによって、第一棒金具３０ａと第二棒金具３０ｂとを干渉させることなく同一高さに設けることができ、鉛直木材１０の同一高さにおける三つあるいは四つの側面に水平木材２０を取付けることができる。なお、小径軸部３１ｂを大径軸部３１ａに貫通させる具体的な手段としては、大径軸部３１ａに小径軸部３１ｂが通過できる貫通孔３１ｃを穿設すると良い。
【００２４】
なお、この接合金具における板状接合部分Ｊについて詳述すると、まず、前記接合具Ｋの頭部３２（３２ａ，３２ｂ）を水平方向に挿通可能な径を有する孔４０が穿けられている。しかも、その孔４０には、孔４０を挿通した頭部３２に結合された軸部の鉛直上方への進入を許すが、前記頭部３２の水平方向の進入を阻止する幅の切り込み４１が上側に連設されていて、全体として柄が付いた丸い杓子の形状である。その頭部３２が孔４０に挿通することによって接合具Ｋに対する板状接合部分Ｊの位置決めが行われる。なお、その切り込み４１の方向は、孔４０の半径方向であれば、その周上の位置に特に制限されるものではない。この板状接合部分Ｊは、水平木材２０に挿入組付けされる円筒部分４６に、鉛直板４５を介して一体設されている。
【００２５】
次に本発明の第二実施形態に係る接合金具について、図４および図５を参照して、説明する。図４は、接合金具の接合具を示すもので、（ａ）は正面図、（ｂ）は側面図である。図５（ａ）は接合の手順を示す斜視図で、（ｂ）は接合後の状態を示す断面図である。
【００２６】
この接合金具の特徴は、接合具Ｋが、複数の第一棒金具１３０ａ、第二棒金具１３０ｂおよび補強板１３３とで構成されていることである。第一棒金具１３０ａは、鉛直木材１０の第一の側面１１から相対向する第三の側面１３に、左側と右側において上下に二本挿通する大径軸部１３１ａの両端部に第一頭部１３２ａを設けて構成される。第二棒金具１３０ａは、第一の側面１１に隣接する第二の側面１２から相対向する第四の側面１４に、第一棒金具１３０ａと同一高さにおいて、大径軸部１３１ａを貫いて、左側と右側において上下に二本挿通する小径軸部１３１ｂの両端部に第二頭部１３２ｂを設けて構成される。また、補強板１３３は、第一棒金具１３０ａおよび第二棒金具１３０ｂの第一頭部１３２ａおよび第二頭部１３２ｂと鉛直木材１０との間に、当該第一棒金具１３０ａおよび第二棒金具１３０ｂに固定された状態で設けられる。
【００２７】
この接合具Ｋにおいても、第一実施形態と同様に、小径軸部１３１ｂを大径軸部１３１ａに貫通させることによって、第一棒金具１３０ａと第二棒金具１３０ｂとを干渉させることなく同一高さに設けることができるので、鉛直木材１０の同一高さにおける三つあるいは四つの側面に水平木材２０を取付けることができる。なお、補強板１３３を設けたことによって、第一棒金具１３０ａおよび第二棒金具１３０ｂの鉛直木材１０に対する組付き力を高めることができ、水平木材２０をより強固に鉛直木材１０に取付けることができる。
【００２８】
なお、この接合金具における板状接合部分Ｊについて詳述すると、まず、前記接合具Ｋの頭部１３２（１３２ａ，１３２ｂ）を水平方向に挿通可能な径を有する孔１４０が穿けられている。しかも、その孔１４０には、孔１４０を挿通した頭部１３２に結合された軸部の鉛直上方への進入を許すが、前記頭部１３２の水平方向の進入を阻止する幅の切り込み１４１が上側に連設されていて、全体として柄が付いた丸い杓子の形状である。その頭部１３２が孔１４０に挿通することによって接合具Ｋに対する板状接合部分Ｊの位置決めが行われる。なお、その切り込み１４１の方向は、孔１４０の半径方向であれば、その周上の位置に特に制限されるものではない。この板状接合部分Ｊは、水平木材２０に挿入組付けされる円筒部分４６に、鉛直板４５を介して一体設されている。
【００２９】
なお、この接合具Ｋの上部には係止部材７０が設けられている。そのため、孔１４０を挿通した頭部１３２に結合された軸部１３１が鉛直上方へ進入（板状接合部分Ｊが下降）するときは、係止部材７０の下部が板状接合部分Ｊに押されて後退するため、切り込み１４１に進入（板状接合部分Ｊの下降）可能であるが、それから板状接合部分Ｊが上昇しようとすると、復元した係止部材７０の下端にロックされて、その上昇は阻止される。
【００３０】
本発明の第三実施形態に係る接合金具について、図６を参照して説明する。図６は接合金具の接合具を示すもので、（ａ）は正面図、（ｂ）は側面図である。この接合金具の特徴は、接合具Ｋが、第一金具２３０ａと第二金具２３０ｂとで構成されていることである。
第一金具２３０ａは、鉛直木材１０の第一の側面１１および第三の側面１３に組付く一対の第一補強板２３３ａ間を、左側と右側において上下に二本挿通する軸部２３１の両端部に第一頭部２３２ａを設けて構成される。また、第二金具２３０ｂは、第二の側面１２および第四の側面１４に組付く一対の第二補強板２３３ｂ間を、前記第一軸部２３２ａと高低差を設けて、左側と右側において上下に二本挿通する連結棒２３４で連結し、その第二補強板２３３ｂ外面の前記第一頭部２３２ａと同一高さ部分に第二頭部２３２ｂを溶接等により固着して構成される。なお、連結棒２３４は、その頭部が補強板２３３から突出しない皿ネジ等の埋込みネジ２３５で固定されている。
【００３１】
この接合具Ｋにおいては、第一補強板２３３ａの軸部２３１と、第二補強板２３３ｂの連結棒２３４とを高低差を設けて挿通しているので、両者が干渉せず、よって両補強板２３３ａ，２３３ｂを鉛直木材１０に固定することができる。また、第二補強板２３３ｂの外面に、第一頭部２３２ａと同一高さにおいて第二頭部２３２ｂを設けているので、鉛直木材１０の同一高さにおける三つあるいは四つの側面に水平木材２０を取付けることができる。
【００３２】
なお図示を省略したが、接合具Ｋに接合される板状接合部分Ｊは、図５に示したものと同一であり、第一頭部２３２ａ又は第二頭部２３２ｂを水平方向に挿通可能で、その挿通によって位置決めを行う孔１４０を有している。
【００３３】
本発明の第四実施形態に係る接合金具について、図７を参照して説明する。図７は接合金具の接合具を示すもので、（ａ）は正面図、（ｂ）は側面図である。この接合金具の特徴は、接合具Ｋが、第一金具３３０ａと第二金具３３０ｂで構成されていることである。第一金具３３０ａは、鉛直木材１０の第一の側面１１および第三の側面１３に組付く一対の第一補強板３３３ａ間を、上下に二本挿通する第一軸部３３１ａの両端部に第一頭部３３２ａを設けて構成される。第二金具３３０ａは、第二の側面１２および第四の側面１４に組付く一対の第二補強板間３３３ｂに、前記第一軸部３３１ａと高低差を設けて、上下に二本挿通する第二軸部３３１ｂの両端部に第二頭部３３２ｂを設けて構成される。
【００３４】
そして、板状接合部分Ｊには、少なくとも上下に四つ形成された孔１４０ａ，１４０ｂ，１４０ｃ，１４０ｄが形成され、第一の側面１１および第三の側面１３側では前記上から一番目（最上位）の第１孔１４０ａと上から三番目の第３孔１４０ｃに第一頭部３３２ａを，上から第二番目の第二の側面１２および上から四番目（最下位）の第四の側面１４側では第２孔１４０ｂと第４孔１４０ｄに第二頭部３３２ｂを，それぞれ水平方向に挿通可能でその挿通によって位置決めを行うようにしたものであり、これによれば鉛直木材１０の同一高さにおける三つあるいは四つの側面に水平木材２０を取付けることができる。
【００３５】
【発明の効果】
以上のとおり、本発明の請求項１に記載の接合金具によれば、小径軸部を大径軸部に貫通させたので、第一棒金具と第二棒金具とを干渉させることなく同一高さに設けることができる。従って、鉛直木材の同一高さにおける三つあるいは四つの側面に水平木材を取付けることができる。
【００３６】
また、請求項２に記載の発明によれば、小径軸部を大径軸部に貫通させたので、第一棒金具と第二棒金具とを干渉させることなく同一高さに設けることができる。これにより、鉛直木材の同一高さにおける三つあるいは四つの側面に水平木材を取付けることができる。また、補強板１３３を設けたので、第一棒金具および第二棒金具の鉛直木材に対する組付き力を高めることができ、水平木材をより強固に鉛直木材に取付けることができる。
【００３７】
さらに、請求項３に記載の発明によれば、第一補強板の軸部と、第二補強板の連結棒とを高低差を設けて挿通しているので、両者が干渉せず、よって両補強板を鉛直木材１０に固定することができ、また、第二補強板の外面に、第一頭部と同一高さにおいて第二頭部を設けているので、鉛直木材の同一高さにおける三つあるいは四つの側面に水平木材を取付けることができる。
【００３８】
またさらに、請求項４に記載の発明によれば、上下に設けた二つの第一頭部のそれぞれを板状接合部分の第１孔と第３孔に挿通し、第二頭部のそれぞれを第２孔と第４孔に挿通するので、鉛直木材の同一高さにおける三つあるいは四つの側面に水平木材を取付けることができる。

[Prior art]
For joining columns and beams in wooden houses, traditionally, tenon processing has been used, and generally no metal fittings have been used. However, this has a problem in that the bonding strength tends to be insufficient, and a considerable amount of labor is required for processing the tenon. Therefore, various metal fittings such as bolts and nuts have been developed, and a method of using them together with the hozo is often used.
