Description

【０００１】
【発明の属する技術分野】
本発明は、柱を土台と梁や梁等の水平構造材に継手で連結している建物と、すでに構築している建物の改築方法に関する。
【０００２】
【従来の技術】
現在の木造建築は、柱や梁等を、通称「切り組」と呼ばれる組構造で連結している。切り組は、一方には連結用の貫通孔や溝を設け、この貫通孔に挿通する凸起を他方に設けて連結する。この連結構造は、切り組の加工に、高度な専門の技術が要求されると共に、著しく手間がかかって、施工コストを高くしている。さらに、最も強度の要求される連結部分で、柱や梁等の構造材の一部を切除して連結する構造、すなわち、構造材の一部を断面欠損させる構造が、連結部分の強度を著しく低下させる原因となっている。それは、連結部分に一定以上の荷重がかかると、切り組で生じた弱い部分（断面欠損部分）が折れてしまい、建物が崩壊に向かうからである。すなわち、この構造が、木造建築の耐振性を低下させている。
【０００３】
このような弊害を防止するために、梁や梁等の水平構造材連結部と柱とを連結する建築用の継手が開発されている（特許文献１ないし７参照）。

【発明が解決しようとする課題】
これ等の公報に記載される継手は、柱と梁等の連結強度を強くして、耐震性を向上できる。しかしながら、これ等の公報に記載される継手は、柱を土台や梁に連結する工程で使用するように設計されたものであるから、土台や梁に連結された柱には装着できなかったり、あるいはこの状態で連結できる構造のものは、強固に連結できない欠点がある。したがって、すでに構築されている建物を改築して、耐震強度を相当に向上させることはできない。
【０００６】
本発明者は、現実に柱や土台や梁を嵌合して連結する継手を開発して、現実に多数の建物を構築した。この構造の建物は、柱と土台や梁の連結部分に免震力を越えた荷重がかかったときに、崩壊に向かう力を継手で分散させて保護できるので建物の崩壊を有効に防止できる。ちなみに、この構造の建物は、第三者機関の実験において、在来工法の約４．８倍の強度があることが証明された。この構造の建物は、柱と土台や梁の連結強度を著しく向上できる特長がある。しかしながら、柱を土台や梁に連結して建物の躯体を構築する、いわゆる「建前」の工程に、継手を使用しない従来の工法に比較して著しく手間がかかった。継手を柱や土台等に嵌合するタイミングが特定され、このタイミングを間違うと継手を装着できなくなり、また、柱等に嵌合している継手を特定の位置に配置しながら、柱を土台や梁に連結するからである。さらに、継手で位置決めしながら柱を連結する構造は、継手を固定する位置を正確に調整する必要があって、このことによっても建前に手間がかかった。
【０００７】
本発明は、さらに従来の建物の欠点を解決することを目的に開発されたものである。本発明の重要な目的は、すでに土台や梁に連結している柱に継手を装着して、連結部の強度を著しく向上できる建物とその構築方法を提供することにある。
また、本発明の他の大切な目的は、既存の建物を改築して耐震強度を著しく向上できる建物とその構築方法を提供することにある。
さらにまた、本発明の他の大切な目的は、建前工程の能率を改善しながら、連結強度を向上できる建物とその構築方法を提供することにある。
【０００８】

【発明の実施の形態】
以下、本発明の実施例を図面に基づいて説明する。ただし、以下に示す実施例は、本発明の技術思想を具体化するための具体例を例示するものであって、本発明は建物を下記のものに特定しない。
【００１７】
さらに、この明細書は、特許請求の範囲を理解し易いように、実施の形態に示される部材に対応する番号を、「特許請求の範囲の欄」、および「課題を解決するための手段の欄」に示される部材に付記している。ただ、特許請求の範囲に示される部材を、実施の形態の部材に特定するものでは決してない。
【００１８】
図１の概略斜視図に示す建物は、土台２Ａと梁２Ｂの４隅のコーナーに垂直に固定される隅柱１Ａの上下を隅継手３Ａで土台２Ａと梁２Ｂに連結している。さらに、隅柱１Ａに隣接して土台２Ａと梁２Ｂに連結される中間柱１Ｂも、その上下を中間継手３Ｂで土台２Ａと梁２Ｂに連結している。そして、隅継手３Ａと中間継手３Ｂを筋かい５で連結している。図の建物は、全てのコーナー部分に隅継手３Ａと中間継手３Ｂを設けているが、本発明の建物は、必ずしも全てのコーナー部分を隅継手と中間継手で連結する必要はない。さらに、図に示す建物は、内部に設けられる間仕切り壁６と外壁７との間にできるコーナー部の隅柱１Ａも、隅継手３Ａを介して土台２Ａと梁２Ｂに連結し、さらにこの隅柱１Ａに隣接する中間柱１Ｂを中間継手３Ｂで土台２Ａと梁２Ｂに連結している。このように、間仕切り壁６のコーナー部を隅継手３Ａと中間継手３Ｂで補強している構造は、耐震強度を著しく向上できる特長がある。ただ、間仕切り壁は、必ずしも隅継手と中間継手とで柱を水平構造材に連結する必要はない。
【００１９】
本発明の建物は、継手３のみで柱１を土台２Ａや梁２Ｂに連結するのではない。柱１は、その上下を嵌合構造と継手３の両方で土台２Ａと梁２Ｂに連結される。柱１を土台２Ａや梁２Ｂに連結する嵌合構造は、貫通孔または凹部である被嵌入部を一方に設け、この被嵌入部に嵌入される挿入部を他方に設けて、挿入部を被嵌入部に入れて連結する従来の建物の連結構造である。
【００２０】
図２と図３は建物の壁構造を示す。これ等の図に示す壁構造は、基礎４の上面に水平に固定された土台２Ａの上に、柱１を垂直に固定している。柱１は、隅継手３Ａと中間継手３Ｂを介して土台２Ａに連結されている。柱１の上端には、水平構造材２である梁２Ｂを固定している。水平構造材２も隅継手３Ａと中間継手３Ｂを介して柱１の上端に連結されている。柱１は、１間ないしは半間の間隔で、土台２Ａに垂直に固定されている。土台２Ａに固定される隅継手３Ａと中間継手３Ｂと、水平構造材２に連結される中間継手３Ｂと隅継手３Ａは、筋かい５で対角線状に連結されている。

【００２２】
土台２Ａは、基礎４の上面にアンカーボルト１２を介して固定されている。土台２Ａは、木製の角材で、寸法は、１０〜１２ｃｍ角で、長さは、２〜４ｍのものが用いられる。土台２Ａは、柱１の近傍、または継手３の付近でアンカーボルト１２を介して基礎４に緊結される。アンカーボルト１２は、土台２Ａが基礎４から浮き上がるのを防止して、土台２Ａを基礎４に固定する。アンカーボルト１２は、下端部を基礎４に垂直に埋設され、土台２Ａを貫通して、土台２Ａを基礎４に固定する。
【００２３】
柱１は正角の角材で、主に、すぎ、まつ、ひのき等の針葉樹が用いられる。寸法は９〜１２ｃｍ角で、長さは３〜４ｍが一般的で、２階建ての通し柱用には、主に６ｍのものが用いられる。
【００２４】
水平構造材２である梁２Ｂは、柱１に水平に連結される。梁２Ｂは、建物の周囲に位置して、柱１の上端に連結され、さらに、周囲の梁２Ｂに対して直角に連結される。水平構造材２には、正角または平角の角材が多く用いられる。水平構造材２の長さは、３〜６ｍのものが一般的である。
【００２５】
柱１は、下端を土台２Ａに、上端を梁２Ｂに連結される。柱１は、図４ないし図１３に示す隅継手３Ａと中間継手３Ｂを介して連結される。さらに、図の柱１は、嵌合構造で土台２Ａと梁２Ｂに連結される。図の嵌合構造は、柱１の上下端に突出する挿入部９を設けて、土台２Ａと梁２Ｂである水平構造材２に、この挿入部９を入れて連結する被嵌入部８を設けている。被嵌入部８は、土台２Ａや梁２Ｂを貫通する貫通孔とし、あるいは挿入部９を入れる凹部とすることができる。図の嵌合構造は、柱１に挿入部９を設けて水平構造材２に被嵌入部８を設けているが、柱に被嵌入部を設けて水平構造材に挿入部を設けることもできる。
【００２６】
隅柱１Ａは、下端を土台２Ａのコーナーに、上端を梁２Ｂのコーナーに嵌合構造で連結しながら、隅継手３Ａを介して連結している。隅柱１Ａに隣接して土台２Ａと梁２Ｂに垂直に固定される中間柱１Ｂは、下端を土台２Ａに、上端を梁２Ｂに嵌合構造で連結し、かつ中間継手３Ｂを介して連結している。
【００２７】
隅継手３Ａを図４ないし図７に示す。これ等の図に示す隅継手３Ａは、隅柱１Ａの表面に接して隅柱１Ａに連結される柱連結部３ａと、この柱連結部３ａの直角の２方向に突出するように連結されて、土台２Ａまたは梁２ＢであるＬ字状の水平構造材２を嵌入する水平構造材連結部３ｂと、柱連結部３ａと水平構造材連結部３ｂに連結されている筋かい連結部３ｃとを備える。
【００２８】

【００３３】
隅柱１Ａに隣接して土台２Ａと梁２Ｂに垂直に固定される中間柱１Ｂは、下端を土台２Ａに、上端を梁２Ｂに、嵌合構造で連結しながら、中間継手３Ｂを介して土台２Ａと梁２Ｂに連結している。中間継手３Ｂを図８ないし図１３に示す。これ等の図に示す中間継手３Ｂは、中間柱１Ｂの表面に接して中間柱１Ｂに連結される柱連結部３ａと、この柱連結部３ａの両側に突出するように連結されて、土台２Ａまたは梁２Ｂである直線状の水平構造材２を嵌入する水平構造材連結部３ｂと、柱連結部３ａと水平構造材連結部３ｂに連結されている筋かい連結部３ｃとを設けている。
【００３４】
中間継手３Ｂの水平構造材連結部３ｂは、水平構造材２の水平方向に対向する対向面に接する一対の側壁３１と、一対の側壁３１を連結する連結プレート３２とを備えている。中間継手３Ｂの水平構造材連結部３ｂは、土台２Ａや梁２Ｂ等の直線部分に連結されるので、全体を直線状としている。中間柱１Ｂを土台２Ａに連結する中間継手３Ｂの水平構造材連結部３ｂは、図８と図１０と図１２に示すように、側壁３１の上面を連結プレート３２で連結している。連結プレート３２と側壁３１とで形成されるコ字状の溝に土台２Ａを嵌入して、水平構造材連結部３ｂは土台２Ａに連結される。中間柱１Ｂを梁２Ｂに連結する中間継手３Ｂは、図９と図１１と図１３とに示すように、側壁３１の下面を連結プレート３２で連結している。連結プレート３２と側壁３１とで形成されるコ字状の溝に梁２Ｂを嵌入して、水平構造材連結部３ｂは梁２Ｂに連結される。

【００３６】
さらに、図１２の中間継手３Ｂは、外側プレート３３の内側にＬ字状に折曲している対向プレート３４を固定している。この中間継手３Ｂは、対向プレート３４と外側プレート３３とで囲まれる部分に中間柱１Ｂを嵌入し、中間柱１Ｂを貫通する止ネジ１３の両端を外側プレート３３と対向プレート３４に連結して、中間柱１Ｂを強固に連結できる。
【００３７】
中間柱１Ｂの柱連結部３ａは、図１０と図１１に示すように必ずしも対向プレートを設ける必要はない。この柱連結部３ａは、外側プレート３３を長くして、中間柱１Ｂとの連結強度を向上できる。長い外側プレート３３は、多数の止孔１４を設け、ここに挿入する止ネジ１３でしっかりと中間柱１Ｂに連結できる。
【００３８】
さらに、中間継手３Ｂの筋かい連結部３ｃは、柱連結部３ａの外側プレート３３と水平構造材連結部３ｂの一方の側壁３１に連結されている。図の中間継手３Ｂは、１枚の金属板を折曲加工することなく、柱連結部３ａの外側プレート３３と筋かい連結部３ｃと、柱連結部３ａの一方の側壁３１としている。
【００３９】
土台２Ａに連結される中間継手３Ｂは、中間柱１Ｂを土台２Ａに嵌合構造で連結する状態で中間柱１Ｂを通過させて、中間柱１Ｂを土台２Ａと中間柱１Ｂに嵌合させる柱通過隙間３ｄを設けている。図８と図１０に示す土台２Ａに連結される中間継手３Ｂは、柱連結部３ａから両側に突出する水平構造材連結部３ｂの下面を開口して上面を連結プレート３２で連結し、かつ柱連結部３ａの内側に位置する、水平構造材連結部３ｂの上下両面及び側壁３１を開口して開口部分を柱通過隙間３ｄとしている。
【００４０】
図１２に示す土台２Ａに連結される中間継手３Ｂは、柱連結部３ａから一方（図において右上）に突出する水平構造材連結部３ｂの下面を開口して上面を連結プレート３２で連結し、柱連結部３ａの他方（図において左下）に突出する水平構造材連結部３ｂの上下両面を上下に開口して、開口部分を柱通過隙間３ｄとしている。これ等の中間継手３Ｂは、柱通過隙間３ｄに土台２Ａに固定している中間柱１Ｂを通過させて、土台２Ａと中間柱１Ｂに固定される。
【００４１】
さらに、梁２Ｂに連結される中間継手３Ｂは、中間柱１Ｂを梁２Ｂに嵌合構造で連結する状態で中間柱１Ｂを通過させて、中間継手３Ｂを梁２Ｂと中間柱１Ｂとに嵌合できる柱通過隙間３ｄを設けている。図９と図１１に示す梁２Ｂに連結される中間継手３Ｂは、柱連結部３ａから両側に突出する水平構造材連結部３ｂの上面を開口して下面を連結プレート３２で連結し、かつ柱連結部３ａの内側に位置する、水平構造材連結部３ｂの上下両面及び側壁３１を開口して開口部分を柱通過隙間３ｄとしている。
【００４２】
図１３に示す梁２Ｂに連結される中間継手３Ｂは、柱連結部３ａから一方（図において左下）に突出する水平構造材連結部３ｂの上面を開口して下面を連結プレート３２で連結し、柱連結部３ａの他方（図において右上）に突出する水平構造材連結部３ｂの上下両面を上下に開口して、開口部分を柱通過隙間３ｄとしている。これ等の中間継手３Ｂは、柱通過隙間３ｄに梁２Ｂに固定している中間柱１Ｂを通過させて、梁２Ｂと中間柱１Ｂに固定される。
【００４３】
さらに、図１と図３に示すように、建物の内部に設けられる間仕切り壁６と外壁７との間にできるコーナー部の隅柱１Ａに配置される隅継手３Ａを図１４ないし図１６に示す。これ等の図に示す隅継手３Ａは、隅柱１Ａの表面に接して隅柱１Ａに連結される柱連結部３ａと、この柱連結部３ａから直角の３方向に突出するように連結されて、Ｔ字状に連結された土台２Ａまたは梁２Ｂである水平構造材２を嵌入する水平構造材連結部３ｂと、柱連結部３ａと水平構造材連結部３ｂに連結されている筋かい連結部３ｃとを備える。
【００４４】
これらの図に示す隅継手３Ａの水平構造材連結部３ｂは、Ｔ字状に連結された土台２Ａや梁２Ｂ等の連結部に連結されるので、直角の３方向に突出してなるＴ字状としている。すなわち、これらの水平構造材連結部３ｂは、水平構造材２の直線部分に嵌入される直線連結部と、この直線連結部の内側に突出して設けられて、水平構造材２の直角連結部分が嵌入される内側連結部とで構成される。直線連結部と内側連結部とで構成される水平構造材連結部３ｂは、水平構造材２の水平方向に対向する対向面に接する一対の側壁３１と、一対の側壁３１を連結する連結プレート３２とを備えている。隅柱１Ａを土台２Ａに連結する隅継手３Ｂの水平構造材連結部３ｂは、図１４と図１６に示すように、直線連結部に配置された２対の側壁３１の上面を連結プレート３２で連結している。さらに、この水平構造材連結部３ｂは、内側連結部の一対の側壁３１の上面を連結プレートで連結することなく、その間に土台２Ａの直角連結部分を入れることができる隙間を設けている。連結プレート３２と側壁３１とで形成されるコ字状の溝に土台２Ａの直線部分を嵌入すると共に、連結プレートを連結していない側壁３１の間に土台２Ａの直角連結部分を嵌入して、水平構造材連結部３ｂは土台２Ａに連結される。隅柱１Ａを梁２Ｂに連結する中間継手３Ｂは、図１５に示すように、直線連結部に配置された２対の側壁３１の下面を連結プレート３２で連結している。さらに、この水平構造材連結部３ｂは、内側連結部の一対の側壁３１の下面を連結プレートで連結することなく、その間に梁２Ｂの直角連結部分を入れることができる隙間を設けている。連結プレート３２と側壁３１とで形成されるコ字状の溝に梁２Ｂの直線部分を嵌入すると共に、連結プレートを連結していない側壁３１の間に梁２Ｂの直角連結部分を嵌入して、水平構造材連結部３ｂは梁２Ｂに連結される。
【００４５】
隅継手３Ａの柱連結部３ａは、隅柱１Ａの外側に接する外側プレート３３を備えている。さらに、図１４と図１５の隅継手３Ａは、外側プレート３３の内側に一対の対向プレート３４を固定している。一対の対向プレート３４は、外側プレート３３に対して直交すると共に、その間に隅柱１Ａを入れることができる間隔としている。この構造の柱連結部３ａは、対向プレート３４の内側に隅柱１Ａを配設して、隅柱１Ａを対向プレート３４に連結できる。この柱連結部３ａは、隅柱１Ａを貫通する止ネジ１３の両端を一対の対向プレート３４に連結して、隅柱１Ａを強固に連結できる。さらに、外側プレート３３の止孔１４から隅柱１Ａに止ネジ１３をねじ込んで連結することもできる。ただ、隅継手３Ａの柱連結部３ａは、図１６に示すように、必ずしも対向プレートを設ける必要はない。この柱連結部３ａは、外側プレート３３を長くして、隅柱１Ａとの連結強度を向上できる。長い外側プレート３３は、多数の止孔１４を設け、ここに挿入する止ネジ１３でしっかりと隅柱１Ａに連結できる。
【００４６】
さらに、これらの隅継手３Ａの筋かい連結部３ｃは、柱連結部３ａの外側プレート３３と水平構造材連結部３ｂの直線連結部の一方の側壁３１に連結されている。図の隅継手３Ａは、１枚の金属板で、柱連結部３ａの外側プレート３３と筋かい連結部３ｃと、柱連結部３ａの一方の側壁３１としている。さらに、図１４と図１５に示す隅継手３Ａは、柱連結部３ａの外側プレート３３に固定している一方の対向プレート３４と、水平構造材連結部３ｂの内側連結部の一方の側壁３１に連結して筋かい連結部３ｃを設けている。この筋かい連結部３ｃは、１枚の金属板で、対向プレート３４と筋かい連結部３ｃと側壁３１とを構成している。
【００４７】
さらに、図１４と図１６に示す隅継手３Ａは、隅柱１Ａを土台２Ａに嵌合構造で連結する状態で隅柱１Ａを通過させて、隅継手３Ａを土台２Ａと隅柱１Ａに嵌合させる柱通過隙間３ｄを設けている。この隅継手３Ａは、柱連結部３ａから両側に突出する水平構造材連結部３ｂの直線連結部の下面を開口して上面を連結プレート３２で連結し、かつ柱連結部３ａの内側に位置する、水平構造材連結部３ｂの上下両面及び側壁３１を開口し、さらに直線連結部から内側に突出する内側連結部の上下両面を開口して、この開口部分を柱通過隙間３ｄとしている。この柱通過隙間３ｄに、土台２Ａに固定している隅柱１Ａを通過させて、隅継手３Ａは土台２Ａと隅柱１Ａに嵌入して固定される。
【００４８】
さらに、図１５に示す隅継手３Ａは、隅柱１Ａを梁２Ｂに嵌合構造で連結する状態で隅柱１Ａを通過させて、隅継手３Ａを梁２Ｂと隅柱１Ａとに嵌合できる柱通過隙間３ｄを設けている。この図に示す梁２Ｂに連結される隅継手３Ａは、柱連結部３ａから両側に突出する水平構造材連結部３ｂの直線連結部の上面を開口して下面を連結プレート３２で連結し、かつ柱連結部３ａの内側に位置する、水平構造材連結部３ｂの上下両面及び側壁３１を開口し、さらに直線連結部から内側に突出する内側連結部の上下両面を開口して、この開口部分を柱通過隙間３ｄとしている。この柱通過隙間３ｄに、梁２Ｂに固定している隅柱１Ａを通過させて、隅継手３Ａを梁２Ｂと隅柱１Ａに嵌入して固定する。
【００４９】
以上に示す隅継手３Ａと中間継手３Ｂは、水平構造材連結部３ｂと柱連結部３ａに止孔１４を設けている。水平構造材連結部３ｂは、対向して配設される一対の側壁３１の対向する位置に止孔１４を設けて、水平構造材２を貫通する止ネジ１３の両端を側壁３１に連結する。柱連結部３ａは、外側プレート３３と対向プレート３４とを柱１の対向面に配置できる構造にあっては、対向する位置に止孔１４を設けて、柱１を貫通する止ネジ１３の両端を外側プレート３３や対向プレート３４に連結する。
【００５０】
筋かい連結部３ｃにも止孔１４を設けており、この止孔１４に止ネジ１３を挿通し、止ネジ１３で筋かい５を連結する。
【００５１】
柱と水平構造材には、止ネジを挿通する位置にあらかじめ貫通孔を設けることができる。この柱や水平構造材は、貫通孔に止ネジをスムーズに挿通できる。ただ、柱や水平構造材には、必ずしも貫通孔を設ける必要はない。隅継手３Ａや中間継手３Ｂを定位置にセットする状態で、止孔１４にドリルを入れて簡単に孔を開けることができるからである。
【００５２】
水平構造材連結部３ｂは、止ネジ１３を水平方向に貫通させて、水平構造材２を固定できるように、互いに対向する両側の側面に止孔１４を設けている。止孔１４に挿入された止ネジ１３は、水平構造材２を貫通し、あるいは水平構造材２に止ねじ込まれて、水平構造材連結部３ｂを水平構造材２に固定する。
【００５３】
水平構造材連結部３ｂは、止孔１４を複数個設け、各々の止孔１４に止ネジ１３を挿通して、水平構造材連結部３ｂをしっかりと水平構造材２に固定できる。さらに、水平構造材連結部３ｂには、基礎４に固定しているアンカーボルト１２を挿通するための止孔１４を連結プレート３２に設けて、土台２Ａにしっかりと固定できる。
【００５４】
図８の中間継手３Ｂは、水平構造材連結部３ｂに土台２Ａを嵌入し、土台２Ａの上面に突出するアンカーボルト１２を水平構造材連結部３ｂの連結プレート３２に設けた止孔１４に貫通させる。アンカーボルト１２は、土台２Ａと水平構造材連結部３ｂの連結プレート３２を貫通して、水平構造材連結部３ｂを土台２Ａと基礎４にしっかりと固定する。さらに、水平構造材連結部３ｂは、水平構造材連結部３ｂの側壁３１に設けた止孔１４から止ネジ１３を貫通するように挿通して、土台２Ａにボルト止することもできる。さらに、隅継手３Ａと中間継手３Ｂは、これらの２つの構造を併用して、より強固に土台２Ａに固定できる。
【００５５】
また、水平構造材連結部３ｂと柱連結部３ａと筋かい連結部３ｃに設ける止孔１４は、スリット孔とすることができる。スリット孔は、止ネジ１３を挿通する位置を微調節できる。特に、水平構造材連結部３ｂをアンカーボルト１２と連結する止孔１４と、筋かい連結部３ｃの止孔１４は、スリット孔が有効である。アンカーボルト１２は、基礎４に埋め込まれて固定されるため、その位置が多少ズレる可能性があるからである。また、筋かい５は、隣接する継手の間隔と柱の高さによって角度が変わる。したがって、スリット孔である筋かい連結部３ｃの止孔１４は、筋かい５の角度が異なる場合においても、９０度の範囲で適用できる。
【００５６】
図２の筋かい５は、対角線状に連結されるクロス部分に補強プレート１０を固定している。補強プレート１０は金属板である。ただ、金属板でない板材も使用できる。補強プレート１０は、連結ボルト１１で筋かい５の交点に連結される。連結ボルト１１は、２本の筋かい５が交差する部分と、補強プレート１０を貫通して、筋かい５と補強プレート１０を連結する。連結ボルト１１は先端に平ワッシャを介してナットをねじ込んで補強プレート１０を連結する。さらに、補強プレート１０を貫通する複数の釘を筋かい５に打ち込んで、筋かい５と補強プレート１０とをより強固に固定している。クロスする２本の筋かい５は、クロス部分に補強プレート１０を固定して、構造材の骨組みをより強固にできる。
【００５７】
隅継手３Ａと中間継手３Ｂは、柱連結部３ａ、水平構造材連結部３ｂの側壁３１に、仮止め用の釘孔１５を設けることができる。釘孔１５を有するこれらの隅継手３Ａや中間継手３Ｂは、釘孔１５から柱１や水平構造材２に向かって釘を打ち込んで、隅継手３Ａと中間継手３Ｂを仮止めできる。とくに、柱１と梁２Ｂとを連結する隅継手３Ａと中間継手３Ｂは、落下しないように仮り止めできるので、能率よく施工できる。
【００５８】
さらに、図２と図３に示す建物の壁構造は、コーナー部で互いに交差する壁に配設された中間継手３Ｂ同士を火打１７で連結している。これらの図に示す火打１７は、交差する土台２Ａ同士を中間継手３Ｂの部分で互いに連結する土台火打１７Ａと、交差する梁２Ｂ同士を中間継手３Ｂの部分で互いに連結する梁火打１７Ｂとを備える。図に示す火打１７は、木製の構造材を所定の長さに切断したもので、土台２Ａや梁２Ｂに接触する連結部分を面取り加工している。さらに、木製の火打１７は、両端部に連結孔を貫通して開口しており、この連結孔に挿通される連結ボルト１１を介して中間継手３Ｂに連結している。この連結ボルト１１には、中間継手３Ｂを土台２Ａや梁２Ｂに連結する連結ボルト１１が併用できる。この連結ボルト１１には、土台２Ａや梁２Ｂと火打１７とを貫通できる十分な長さのものを使用する。火打１７は、たとえば、中間継手３Ｂの水平構造材連結部３ｂの側壁３１に連結される。ただ、火打は、図示しないが、金属製の金物火打とすることもできる。金物火打は、両端に、中間継手に連結される連結片を設けて、この連結片に開口した連結孔に連結ボルトを挿通して中間継手を介して土台や梁に連結される。このように、コーナー部を形成する壁の土台２Ａや梁２Ｂを火打１７で連結する構造は、ねじれ応力に対する強度を向上でき、極めて強靭な構造とすることができる。
【００５９】
以上の建物は、以下の工程で施工される。
［柱１を土台２Ａと梁２Ｂに嵌合構造で連結する建前工程］
(1) 柱１と土台２Ａと梁２Ｂとを、嵌合構造で連結できるように切削加工する。図は、柱１に挿入部９を設けて、土台２Ａと梁２Ｂに挿入部９を嵌合する貫通孔や凹部からなる被嵌入部８を設けるように加工している。
(2) 柱１の下端を土台２Ａに嵌合構造で連結する。柱１は、下端に設けている挿入部９を、土台２Ａの上面に開口するように設けている貫通孔や凹部等の被嵌入部８に入れて土台２Ａに連結するので、定位置に能率よく連結される。。
(3) 柱１の上端に梁２Ｂを嵌合構造で連結する。柱１の上端に設けている挿入部９に、梁２Ｂに設けている貫通孔や凹部等の被嵌入部８を入れて、柱１と梁２Ｂとを連結するので、柱１と梁２Ｂは位置ずれしないように連結される。
【００６０】
［隅継手と中間継手を連結する工程］
(1) 土台２Ａのコーナー部に隅継手３Ａを固定する。このとき隅継手３Ａは、土台２Ａに固定している柱１を柱通過隙間３ｄに通過させて、土台２Ａと柱１の定位置にセットされる。
(2) 土台２Ａに連結している中間柱１Ｂと土台２Ａとに中間継手３Ｂを固定する。中間継手３Ｂは、土台２Ａに固定している柱１を柱通過隙間３ｄに通過させて、土台２Ａと柱１の定位置にセットされる。
(3) 梁２Ｂのコーナー部に隅継手３Ａを固定する。このとき隅継手３Ａは、梁２Ｂに固定している柱１を柱通過隙間３ｄに通過させて、梁２Ｂと柱１の定位置にセットされる。定位置にセットされた隅継手３Ａは、釘孔１５に釘を打ち込んで仮止めされる。
(4) 梁２Ｂに連結している中間柱１Ｂと梁２Ｂとに中間継手３Ｂを固定する。中間継手３Ｂは、梁２Ｂに固定している柱１を柱通過隙間３ｄに通過させて、梁２Ｂと柱１の定位置にセットされる。定位置にセットされた隅継手３Ａは、釘孔１５に釘を打ち込んで仮止めされる。
(5) 上下の隅継手３Ａと中間継手３Ｂとの筋かい連結部３ｃに筋かい５を連結する。筋かい５は、筋かい連結部３ｃの止孔１４に挿通される止ネジ１３で連結されるが、止ネジ１３は完全には締め付けしない。柱１の垂直調整をするためである。止ネジ１３は大きな木ネジで、止孔１４から筋かい５にねじ込まれて、筋かい５を筋かい連結部３ｃに連結する。
(6) 土台２Ａと梁２Ｂとを交差するように引張連結具で連結し、引張連結具で柱１が正確に垂直になるように調整する。この工程は、全ての木造建物においてすでに行われてる工程である。
(7) 柱１を垂直に調整した後、隅継手３Ａと中間継手３Ｂの止孔１４に止ネジ１３を入れて、隅継手３Ａと中間継手３Ｂとを土台２Ａと柱１と梁２Ｂとに連結して固定し、さらに、筋かい連結部３ｃにねじ込んでいる止ネジ１３を完全に締め付けて固定する。止ネジ１３は、図１７に示すように、柱１や水平構造材２等の構造材を貫通し、両端を止孔１４に挿通してしっかりと連結される。この止ネジ１３にはボルトが使用でき、ボルトは止孔１４と構造材とを貫通して先端にナット１６をねじ込んで固定される。さらに、止ネジ１３は、図１８に示すように、止孔１４から構造材に向かってねじ込まれる大きな木ネジとすることもできる。大きな木ネジは、柱１や水平構造材２等に中心部分までねじ込まれる長さを有し、太い部分の直径を約１０ｍｍとするものである。ただ、木ネジである止ネジは、小さいものを多数に柱や水平構造材にねじ込んで連結することもできる。
【００６１】
以上の施工工程は、新築建物の構築方法であるが、本発明の建物の構築方法は、耐震強度が向上するように改築するのにも適している。建物の改築には、隅継手３Ａと中間継手３Ｂとを固定できるように外壁７を除去する。その後の工程は、前述の［隅継手と中間継手を連結する工程］の工程と同じである。建物の改築時には、外部からの施工が可能であるため、建物の内部で生活をしながら補強できる特長がある。
【００６２】
【発明の効果】
本発明の建物とその構築方法は、すでに土台や梁に連結している柱に継手を装着して、連結部の強度を著しく向上できる特長がある。それは、本発明の建物とその構築方法が、挿入部を被嵌入部に入れて連結する嵌合構造で、柱の上下を水平構造材である梁と土台に連結すると共に、互いに連結された柱と水平構造材とに独特の構造の継手を連結して固定しているからである。この継手は、柱を水平構造材に嵌合構造で連結する状態で柱を通過させる柱通過隙間を設けており、この柱通過隙間に柱を通過させて、嵌合構造で連結している水平構造材と柱とに固定できるようにしている。この構造の継手は、既に連結している柱と水平構造材とに、簡単かつ容易に装着できる。このため、本発明の建物とその構築方法は、柱と水平構造材とを嵌合構造で連結する工程を従来の工法で行うことができ、しかもこの工程で連結された柱と水平構造材とに、簡単に継手を連結して固定できる。したがって、本発明の建物とその構築方法は、躯体を構築する手順やタイミングが複雑でなく、いいかえると建前工程の能率を改善しながら、これらの連結部の強度を著しく向上できる。さらに、本発明は、連結された状態の柱と水平構造材とに継手を連結してこれらの連結部分を補強するので、既存の建物を改築して耐震強度を著しく向上することも可能である。
【００６３】
さらに、本発明の建物とその構築方法は、建物のコーナーに配設している隅柱の上下に固定された隅継手と、この隅柱に隣接して配設された中間柱の上下に固定された中間継手とを対角線状に筋かいで連結しているので、筋かいでもって、これらの継手を連結して極めて強靭な構造にできる特長もある。

BACKGROUND OF THE INVENTION
The present invention relates to a building in which a pillar is connected to a base and a horizontal structural member such as a beam or a beam by a joint, and a method for remodeling a building that has already been constructed.
[0002]
[Prior art]
In current wooden architecture, pillars, beams, etc. are connected by a group structure called a “cut group”. The cut braid is provided with a connecting through-hole or groove on one side, and a protrusion protruding through the through-hole is provided on the other side for connection. This connection structure requires highly specialized techniques for cutting and processing, and requires a lot of time and increases the construction cost. Furthermore, the structure that cuts and connects part of the structural material such as pillars and beams at the connection part where the strength is required, that is, the structure in which a part of the structural material is broken in cross section significantly increases the strength of the connection part. It is a cause of lowering. This is because if a load of a certain level or more is applied to the connecting portion, a weak portion (cross-sectional missing portion) generated by cutting is broken and the building is going to collapse. That is, this structure reduces the vibration resistance of the wooden building.
[0003]
In order to prevent such an adverse effect, an architectural joint that connects a horizontal structural member connecting portion such as a beam or a beam and a column has been developed (see Patent Documents 1 to 7).

[Problems to be solved by the invention]
The joints described in these publications can improve the earthquake resistance by increasing the connection strength between columns and beams. However, since the joints described in these publications are designed to be used in the process of connecting the column to the base or beam, it cannot be attached to the column connected to the base or beam, Or the thing of the structure which can be connected in this state has the fault which cannot be connected firmly. Therefore, it is impossible to significantly improve the seismic strength by renovating a building that has already been constructed.
[0006]
The present inventor has developed a joint that actually connects and connects columns, foundations, and beams, and has actually built a large number of buildings. Buildings with this structure can be effectively prevented from collapsing because they can protect the joints between the pillars, foundations and beams by dispersing joints with a force that exceeds the seismic isolation force. By the way, it was proved that the building of this structure is about 4.8 times stronger than the conventional method in a third party experiment. Buildings with this structure have the advantage of significantly improving the connection strength between pillars, foundations and beams. However, the so-called “building” process, in which the pillars are connected to the foundations and beams to construct the building frame, is significantly more laborious than the conventional method using no joints. The timing for fitting the joint to the pillar, foundation, etc. is specified, and if this timing is incorrect, the fitting cannot be mounted, and the joint fitted to the pillar, etc. is placed at a specific position while the pillar is This is because it is connected to the beam. Furthermore, in the structure in which the pillars are connected while being positioned by the joint, it is necessary to accurately adjust the position at which the joint is fixed.
[0007]
The present invention has been developed for the purpose of solving the drawbacks of conventional buildings. An important object of the present invention is to provide a building capable of remarkably improving the strength of a connecting portion by attaching a joint to a column already connected to a base or a beam, and a construction method thereof.
In addition, another important object of the present invention is to provide a building and a method for constructing it, which can renovate an existing building and significantly improve the seismic strength.
Furthermore, another important object of the present invention is to provide a building that can improve the connection strength while improving the efficiency of the pre-building process, and a construction method thereof.
