Description

【0001】
【発明の属する技術分野】
本願発明は、木造建築物における柱と梁とを接合する構造に係り、特に柱と梁との接合部で相対的な変形が拘束され、双方間で曲げモーメントの伝達が生じる柱梁接合構造に関する。
【0002】
【従来の技術】
一般に普及している木造建築物では古くから柱と梁とを、柱に設けたほぞ穴に梁の端部を加工したほぞを差し入れることによって接合している。このような接合構造では、双方間における変形を許容し、曲げモーメントの伝達は行われない。つまり、曲げモーメントに抵抗することができず、複数の柱および複数の梁(胴差、軒けた、土台等の横方向に架設される部材を含む)で形成される軸組みは、変形が生じ易い。このため、柱間の壁内に筋交いを配置し、地震時等の水平方向力によって軸組みが変形しようとするのに抵抗するものとなっている。
【0003】
筋交いは、一般的に複数の位置に設けられ、さらに直交する二つの方向に必要となる。したがって、従来の木造建築物では筋交いを設ける壁体を確保する必要があるために、開口部の設定や屋内空間の利用に支障を生じることもある。このような事情から、柱と梁とをいわゆる剛結合、つまり曲げモーメントの伝達が生じる結合とし、軸組みをラーメン構造とする提案がなされている。
【0004】
特許公報第2798239号に記載の接合構造は、梁と柱との双方に、外周面に雄ネジを有する棒鋼を水平方向にねじ込み、これらを継ぎ手金具を介して連結するものである。
特開2000−265553号公報に記載の接合構造は、梁又は柱のいずれか一方にラグスクリューボルトをねじ込み、他方に切り欠き部を設けてこの部分に係止したボルトを上記ラグスクリューボルトに連結するものである。
【0005】
また、特許公報第2653414号に記載の接合構造は、柱にラグスクリューボルトを水平にねじ込み、梁には端面全域を覆うようにガセットプレートを取り付ける。そして、ラグスクリューボルトの端部に螺合したナットによってガセットプレートとラグスクリューボルトとを締結するものである。
上記のような接合構造によって、木造の軸組みをラーメン構造とし、筋交いを低減又は不要とすることができ、設計の自由度が大幅に拡大する。
【0006】
【発明が解決しようとする課題】
しかしながら、上記のような従来から知られている接合構造では、次のような未解決の課題がある。
特許公報第2798239号及び特許公報第2653414号に記載の接合構造では、柱の側面に梁の端面を突き当てて接合するものである。このため、接合面には曲げモーメントと大きなせん断力が作用する。この大きなせん断力に抵抗するために、梁端面の全域を覆うような大きな金属製の接合用部材を用いるものとなっている。このように大きな接合用の部材を用いると特許公報第2798239号に示されるように、接合部の構造が複雑になったり、特許公報第2653414号に示される構造のように接合用部材を木部材に固着するのに多数のピンが必要となったりする。そして、加工の作業量及び費用が増大することになる。また、金属製の接合部材を固着するために、梁の軸線方向つまり木目の方向に複数のスクリュー部材をねじ込む構造では、梁に割れ等が生じるおそれもある。
【0007】
一方、特開2000−265553号公報に記載されるように、木部材に切り欠きを設けてボルトを係止する構造では、切り欠きから木材の割れ等が生じ、構造上の弱点になることがある。
【0008】
本願発明は、上記のような事情に鑑みてなされたものであり、その目的は、簡単な構造で曲げモーメントを確実に伝達することが可能な木製の柱と梁との接合構造を提供するものである。
【0009】
【課題を解決するための手段】
上記課題を解決するために、請求項1に係る発明は、 木製梁に所定間隔をあけて設けられた二つの鉛直方向の穴に、外周部に螺旋状の張り出し部を有するスクリュー部材がそれぞれねじ込まれ、 木製柱の下端部又は上端部における柱幅方向(梁の軸線方向)の両側端部に、それぞれ柱固定金具が固着されており、 該木製柱の下端面又は上端面の、柱幅方向における中央部が前記木製梁の上面又は下面に当接され、 前記スクリュー部材の上端部又は下端部が前記柱固定金具と結合されている柱梁接合構造を提供する。
【0010】
上記構成において、木製の梁及び柱は、双方の軸線を含む面内における部材幅がこの面に対して厚さ方向の部材寸法より大きいものを用いるのが望ましい。つまり、梁と柱とを接合してラーメン構造を形成したときに曲げモーメントが作用する方向の部材寸法を大きくすることによって本発明の効果がより顕著となるものである。ここで梁は、胴差、軒けた、土台等の横方向に架設される部材一般を含むものである。
また、上記柱固定金具を木製柱に固着する手段は、例えば請求項2に記載された構造を採用することができるが、これに限定されるものではなく、柱の軸線方向に大きな力を伝達することが可能な様々な構造を採用することができる。
【0011】
この接合構造では、柱の上端面又は下端面が梁の下面又は上面に当接されるものであり、接合面には、曲げモーメントと大きな支圧力(接合面と垂直な方向の力)とが作用し、大きなせん断力(接合面と平行な方向の力)は、作用しない。したがって、柱の中央部が直接に梁に当接されて大きな鉛直方向の力を伝達する。一方、両側端部に固着された柱固定金具は、曲げモーメントが作用したときに柱の軸線方向に生じる圧縮力と引張力とを梁に伝達するものとなり、柱固定金具及びこの柱固定金具と木製の柱とを固着する部分に作用する力は小さく抑えられる。このため、柱固定金具及びその取り付け部分を簡単な構造とすることができる。
【0012】
また、柱固定金具は梁にねじ込まれたスクリュー部材に結合されており、柱の軸線方向の圧縮力及び引張力がスクリュー部材を介して梁に伝達される。このとき、スクリュー部材は木製梁の上下方向つまり木目と直角の方向に貫入されており、梁を補強する効果を有する。そして、このスクリュー部材を介して梁の断面内の広い範囲に分布して力を伝達することになり、梁内に応力が集中することが少なく、円滑に曲げモーメントが伝達される。
【0013】
請求項2に係る発明は、請求項1に記載の柱梁接合構造において、 前記柱固定金具は、前記木製梁に当接される第1の板部と、該第1の板部の対向する2辺から垂直に立ち上げられた2つの第2の板部とを有し、 前記第1の板部は、ボルト孔を有し、該ボルト孔に挿通された柱固定用ボルトによって前記スクリュー部材と結合されており、 前記第2の板部は、前記木製柱に水平方向に貫入される複数のピン又はボルトで該木製柱に結合されているものとする。
【0014】
この接合構造では、柱固定金具がほぼ平行な2枚の第2の板部を有し、この第2の板部を介して柱との間で力の伝達が行われる。また、柱に柱固定金具を固着するためのピン又はボルトには支圧力と大きなせん断力が作用するが、第2の板部が2枚あることによって分散され、ピン又はボルトの数を低減することも可能となる。
また、第1の板部は1本のボルトで1本のスクリュー部材に結合され、柱及び梁の厚さ方向(それぞれの軸線を含む面に対して直角方向)の部材寸法が小さい場合にも、スクリュー部材を貫入することによって大きな断面欠損を生じることがない。
【0015】
請求項3に係る発明は、請求項2に記載の柱梁接合構造において、 前記木製柱は、前記柱固定金具が取り付けられる位置に、該木製柱の対向する2つの側面間に該側面と平行な2つのスリットを有し、 前記第2の板部は、前記スリット内に挿入して結合されているものとする。
【0016】
この接合構造では、柱固定金具の第2の板部が柱に設けられたスリット内に挿入して結合されているので、柱の対向する2面には柱固定金具が露出しない。したがって、この面を直接に居室内に現し、内装面とすることが可能となる。
【0017】
請求項4に係る発見は、請求項2又は請求項3に記載の柱梁接合構造において、  前記スクリュー部材は、端面が木製梁の表面より内側となるようにねじ込まれ、該端面から該スクリュー部材の軸線方向にねじ穴を有し、 該ねじ穴に螺合されるボルトによって前記柱固定金具の第1の板部が結合されているものとする。
【0018】
この接合構造では、スクリュー部材の端面に設けられたねじ穴にボルトをねじ込むことによって柱固定金具を容易に接合することができる。そして、スクリューボルトの端面が木製梁の下面又は上面より内側にあるので、上記ボルトを強く締め付けると柱の端面を梁の下面又は上面に強く押し付けた状態で接合することができる。これにより、柱と梁との接合部で高い剛性が維持される。
【0019】
請求項5に係る発明は、請求項2に記載の柱梁接合構造において、 前記柱固定金具は、対向する2つの第2の板部を連結し、該第2の板部の座屈を防止するように相互間の間隔を拘束するボルトを有するものとする。
【0020】
柱と梁との間に大きな曲げモーメントが作用すると、柱幅方向の両側端部に設けられた柱固定金具の一方に、柱の軸線方向の大きな圧縮力が作用する。この圧縮力がある限度を超えると第2の板部は座屈を生じるおそれがある。しかし、2枚の第2板部をボルトで連結することにより、第2の板部の側方への変位が拘束され、座屈が有効に防止される。
【0021】
請求項6に係る発明は、請求項1に記載の柱梁接合構造において、 前記スクリュー部材は、側部に軸線と直角方向のねじ穴又は貫通孔が設けられ、 該ねじ穴に螺合されたボルト又は前記貫通孔に挿通されたボルトによって、前記木製梁が他の木製梁と接合されているものとする。
【0022】
この接合構造では、柱に接合された梁に、さらに他の梁が接合され、これら2つの梁間に作用するせん断力、すなわち鉛直方向の力がボルトを介してスクリュー部材に伝達される。スクリュー部材に伝達された鉛直方向の力は、このスクリュー部材の周面からこれが埋め込まれた梁に伝達されるとともに、スクリュー部材から柱にも伝達される。したがって、柱と梁との接合部に他の梁から大きなせん断力が作用しても円滑に力の伝達が行われ、局部的に大きな応力が生じることが少ない。また、スクリュー部材を兼用して柱と梁及び梁と梁を接合することができ、3つの部材の接合部の構造を簡単にすることができる。
【0023】
請求項7に係る発明は、請求項6に記載の柱梁構造において、 前記ねじ穴に螺合されたボルト又は前記貫通孔に挿通されたボルトによって、前記木製梁(第1の木製梁)の側面に梁接合金具が固定され、 該梁接合金具は、前記第1の木製梁の側面に当接される第1の接合板部と、該第1の接合板部とほぼ垂直に設けられた第2の接合板部とを有し、 前記第1の接合板部が前記ボルトによって前記第1の木製梁に固定され、 前記第2の接合板部が、他の木製梁(第2の木製梁)を水平方向に貫通するピン又はボルトによって、該第2の木製梁に固定されているものとする。
【0024】
上記梁接合金具は、スクリュー部材がねじ込まれた梁の側面に取り付けられ、この梁接合金具に作用する鉛直方向の力はボルトを介してスクリュー部材に伝達される。一方、上記梁と接合される他の梁からは、この他の梁を貫通するピン又はボルトを介して梁接合金具に鉛直方向の力が伝達される。したがって、2つの梁間に作用する力は、上記ピン又はボルトから柱接合金具、この柱接合金具を固定するボルト、スクリュー部材を介して伝達され、接合部での相互変位等を生じることなく確実に力が伝達される。
【0025】
請求項8に係る発明は、請求項1に記載の柱梁接合構造において、 前記スクリュー部材は、下端部が、前記木製梁の下面に接合される柱の上端部に固定された柱固定金具に結合され、上端部が、前記木製梁の上面に接合される柱の下端部に固定された柱固定金具に結合されているものとする。
【0026】
この接合構造では、梁にねじ込まれた2本のスクリュー部材に、この梁を下側から支える柱と、この梁の上に立設される柱との双方が連結される。そして、このスクリュー部材を介して、梁と双方の柱との間で円滑に力が伝達される。また、梁の上下に接合される2つの柱は、スクリュー部材を介して連結され、梁によって分離されているにもかかわらず、連続した柱のように高い剛性を有するものとなる。
【0027】
【発明の実施の形態】
以下、本願発明の実施の形態を図に基づいて説明する。
図1は、本願発明の柱梁接合構造が好適に用いられる木造建築物の構造躯体を示す概略斜視図である。
この構造躯体は、木製柱1と木製梁2とを曲げモーメントの伝達が可能に接合したラーメン架構体を複数組み合わせて形成されている。それぞれラーメン架構体を構成する木製柱1(以下、柱という)及び木製梁2(以下、梁という)は、これらの軸線を含む立面と平行な方向の断面寸法を大きく、これと直角方向の断面寸法を小さくして扁平な部材となっている。
【0028】
したがって、各ラーメン架構体の各部材は一方向の曲げに抵抗する部材として用いられ、複数の一方向ラーメンを組み合わせて構造躯体の全体を構成している。各ラーメン架構体は、柱1の上端面に梁2を当接して接合する、いわゆる梁勝ち構造となっており、梁2−1と梁2−2とを接合することによって複数のラーメン架構体が互いに連結されている。
【0029】
図2及び図3は、図1に示すラーメン架構体で用いられる柱梁接合構造であって、本願に係る発明の一実施形態を示す断面図であり、図2は、ラーメン架構体の軸線を含む面と直角方向の断面を、図3は、ラーメン架構体の軸線と平行は断面を示すものである。また、図4,図5及び図6は同じ接合構造の分解斜視図である。
この接合構造は、梁2にねじ込まれた2本のスクリュー部材11と、柱に固着された2つの柱固定金具12とをボルト13によって連結するものであり、2つの柱固定金具13が取り付けられた位置間では、柱の上面1aが直接に梁2の下面の当接されている。
【0030】
上記スクリュー部材11は、図7に側面図及び正面図を示すように、棒状の鋼部材の側面に螺旋状の張り出し部11aを設けたものであり、両端部には端面から軸線方向にねじ穴11bが設けられている。このスクリュー部材11は、図5に示すように、梁2に所定間隔をあけて二つの貫通孔2aを鉛直方向に設け、さらに螺旋状の溝を切削した後にねじ込まれたものであり、スクリュー部材11の上下の端面は、梁の上面及び下面より部材内側となるように長さが設定されている。
【0031】
柱固定金具12は、図6に示すように、梁2の下面と対向する第1の板部12aとこの第1の板部12aの対向する2辺から平行に立ち上げられた2つの第2の板部12bとを有しており、第1の板部12aの中央にはボルト13を挿通する貫通孔12cが設けられている。この第1の板部12aには、曲げ変形が生じないように充分な厚さの鋼板が用いられる。また、第2の板部12bには、ピン14を挿通する複数の穴12dが設けられている。
【0032】
一方、柱1の上端部には、図6に示すように、柱幅方向(梁の軸線方向)の両側端部に切り欠き1bが設けられ、この切り欠き1bから柱の軸線方向の平行な二つのスリット1cが設けられている。このスリット1cには上記柱固定金具の第2の板部12bが挿入され、柱の立面から挿入されたピン14が柱1を貫通するとともに第2の板部12bの上記穴12dに挿通され、柱固定金具12が柱1に固着されるものとなっている。
【0033】
上記柱固定金具12の第1の板部上面は、柱の上端面1aとほぼ一致するか又はやや低位となるように柱固定金具12が固着されており、貫通孔12cに挿通されたボルト13をスクリュー部材11の端部に設けられたねじ穴11bに螺合することによって柱固定金具12とスクリュー部材11とが結合され、柱1と梁2とが接合される。このとき、スクリュー部材11の下面は梁2の下面よりやや上位に位置し、柱固定金具12の上面が柱1の上面よりやや低位にあるので、ボルト13を強く締め付けると柱1の上面が梁2の下面に直接当接されるとともに強く押しつけられる。これにより柱1と梁2とは常に圧接された状態で鉛直方向の力が伝達される。そして、接合部分に作用する曲げモーメントに対しては、スクリュー部材11からボルト13及び柱固定金具12を介して柱1に伝達される引張力及びスクリュー部材11から柱固定金具12を介して柱1に伝達される圧縮力によって抵抗するものとなり、双方の接合部は高い剛性が維持される。
【0034】
上記柱梁接合部に曲げモーメントが作用したときに、柱固定金具12の一方にはボルト13から第1の板部12aに上方への引張力が作用し、他方には、スクリュー部材11又は梁2の下面から第1の板部12aに下方への圧縮力が作用する。上方への引張力が作用したときには、第1の板部12aに曲げ変形が生じるが、第1の板部12aに厚い鋼板を用いることによって曲げモーメントに抵抗させることができる。一方、圧縮力が作用する場合には、第2の板部12bに大きな圧縮力が作用し、この第2の板部12bはスリット1cに挿入するために薄い鋼板が用いられているので、座屈が生じるおそれも考えられる。このような場合には、図8に示すように、柱固定金具12の上部で第2の板部12bをボルト15及びナット16で連結し、第2の板部12bが側方に変形するのを拘束することができる。これにより座屈が生じる圧縮力を著しく増大させることができ、有効に座屈を防止することができる。
【0035】
以上に説明した実施形態は、柱1とその上に支持される梁2とを接合するものであるが、上記梁2の上に2階部分の柱3を立設することができる。この柱3も梁2と曲げモーメントの伝達が可能に接合し、2層のラーメン架構体を形成する場合には、図9に示すように、上記と全く同じ構造を上下に反転して2階部分の柱3を梁2に接合することができる。このとき、梁2に貫入されたスクリュー部材11は、1階部分の柱1の接合に用いたものと共通に用いることができる。これにより、1階部分の柱1と2階部分の柱3とがスクリュー部材11を介して連結され、双方の柱は通し柱に近い剛性を有するものとなる。
【0036】
なお、2階部分の柱3は、上記のように1階部分の柱1と同じ位置に立設されるものに限定されるものではなく、全く位置を変えて立設することができるし、2本のスクリュー部材11の内の一方のみを共通に用いて少しずれた位置に立設することもできる。
【0037】
図10は、柱5と梁6とが接合される部分で、さらに他の梁7が接合される構造を示す概略斜視図である。
この構造では、柱5と第1の梁6とは、図2から6までに示す接合構造と同様に接合されているが、第1の梁6に貫入された2本のスクリュー部材21の内の1本が、その長さ方向の中間部に軸線と直角方向に貫通するねじ穴21aを有するものとなっている。そして、第1の梁6の側面から上記スクリュー部材21のねじ穴21aに通じる横穴6aが第1の梁6に設けられており、この横穴6aに挿通してスクリュー部材21に螺合されたボルト22により、第1の梁6の側面に梁接合金具23が固着されている。
【0038】
上記梁接合金具23は、第1の梁6の側面に当接される第1の接合板部23aと、この第1の接合板部23aの両側縁から直角に立ち上げられた2つの第2の接合板部23bとを有しており、第1の接合板部23aには上記スクリュー部材21に螺合されるボルト22が挿通される穴23cが設けられている。また、2つの第2の接合板部23bには、それぞれの対応する位置にピン25を挿通する穴23dが設けられている。
【0039】
第2の梁7には、端部に鉛直方向の貫通孔7aが設けられ、この貫通孔7aにスクリュー部材24がねじ込まれている。このスクリュー部材24は、軸線方向の中間位置に、軸線と直角方向の貫通孔が設けられ、この貫通孔にピン25が挿通されるようになっている。また、第2の梁7の端部には、この梁の軸線と平行で鉛直方向のスリット7bが、上記スクリュー部材24が貫入された位置の両側に設けられており、このスリット7aに、上記梁接合金具の第2の接合板部23bが挿入される。そして、第2の梁7の側面からピン25が挿入され、上記第2の接合板部23b及びスクリュー部材24の貫通孔24aに挿通することによって梁接合金具23とスクリュー部材24とが結合されている。
【0040】
上記構成により第2の梁7は第1の梁6の側面に当接して接合され、双方の梁間に作用するせん断力は、第2の梁7のスクリュー部材24からピン25、梁接合金具23、ボルト22及び第1の梁のスクリュー部材21を介して第1の梁6に伝達される。このように接合される二つの梁6,7は、鉛直方向すなわち梁の木目と直角方向にスクリュー部材21,24が貫入され、梁が割れたりしないように補強されるとともに、スクリュー部材を介して梁の断面にそのまま断面力が伝達され、局部的に応力が集中するのが回避される。
【0041】
【発明の効果】
以上説明したように、本願発明に係る柱梁接合構造では、柱の上端面又は下端面に当接される梁と柱との間で、曲げモーメントは、梁に貫入されたスクリュー部材及び柱に固着された柱固定金具を介して伝達される。また、鉛直方向の力は梁の下面又は上面から柱の端面に直接に伝達される。これにより簡単な構造で鉛直方向の力と曲げモーメントとが簡単な構造で確実に伝達されるとともに、双方の接合部で高い剛性を維持することができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a structure for joining a column and a beam in a wooden building, and more particularly, to a column-beam joint structure in which relative deformation is restricted at a joint between the column and the beam and bending moment is transmitted between the two. .
[0002]
[Prior art]
In a wooden building which has been widely used, pillars and beams have been joined for a long time by inserting a tenon in which the ends of the beams are processed into tenon holes provided in the pillars. In such a joint structure, deformation between both is allowed, and no bending moment is transmitted. In other words, it cannot withstand the bending moment, and a frame formed by a plurality of columns and a plurality of beams (including members that are erected in the lateral direction such as a girder, a girder, a base, etc.) is deformed. easy. For this reason, a brace is arranged in the wall between the columns, and it is resistant to deformation of the frame due to a horizontal force during an earthquake or the like.
[0003]
Brace is generally provided at a plurality of positions and is required in two orthogonal directions. Accordingly, in a conventional wooden building, it is necessary to secure a wall for providing a brace, which may hinder the setting of an opening and the use of an indoor space. Under such circumstances, a proposal has been made in which a column and a beam are formed as a so-called rigid connection, that is, a connection in which a bending moment is transmitted, and a frame is a rigid frame structure.
[0004]
The joining structure described in Japanese Patent Publication No. 2798239 is to screw a steel bar having an external thread on an outer peripheral surface into both a beam and a column in a horizontal direction, and to connect them via a joint fitting.

[Problems to be solved by the invention]
However, the above-described conventionally-known joining structures have the following unsolved problems.
In the joining structures described in Japanese Patent Publication No. 2798239 and Japanese Patent Publication No. 2653414, an end face of a beam is abutted against a side surface of a pillar for joining. Therefore, a bending moment and a large shear force act on the joint surface. In order to resist this large shearing force, a large metal joining member that covers the entire beam end surface is used. The use of such a large joining member complicates the structure of the joining portion as shown in Japanese Patent Publication No. 2798239, and the joining member is made of a wooden member as in the structure disclosed in Japanese Patent Publication No. 2653414. A large number of pins may be required to fix the pins. And the amount of work and cost of processing will increase. In a structure in which a plurality of screw members are screwed in the axial direction of the beam, that is, in the direction of the grain, in order to fix the metal joining member, the beam may be broken.
[0007]
On the other hand, as described in Japanese Patent Application Laid-Open No. 2000-265553, in a structure in which a notch is provided in a wooden member and a bolt is locked, a crack or the like of wood is generated from the notch, which may be a structural weak point. is there.
[0008]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a joint structure between a wooden column and a beam capable of reliably transmitting a bending moment with a simple structure. It is.
[0009]
[Means for Solving the Problems]
In order to solve the above problem, the invention according to claim 1 is characterized in that screw members having a helical overhang on the outer periphery are screwed into two vertical holes provided at a predetermined interval in a wooden beam. At the lower end or upper end of the wooden column, column fixing brackets are fixed to both ends in the column width direction (axial direction of the beam), respectively. And a center portion of the screw member is in contact with an upper surface or a lower surface of the wooden beam, and an upper end or a lower end of the screw member is coupled to the column fixing bracket.
[0010]
In the above configuration, it is preferable that the wooden beam and the pillar have a member width in a plane including both axes that is larger than a member dimension in a thickness direction with respect to the plane. That is, the effect of the present invention becomes more remarkable by increasing the dimension of the member in the direction in which the bending moment acts when the beam and the column are joined to form the rigid frame structure. Here, the beam includes general members that are erected in the lateral direction, such as a girder, a girder, and a base.
Further, the means for fixing the column fixing bracket to the wooden column can adopt, for example, the structure described in claim 2, but is not limited thereto, and transmits a large force in the axial direction of the column. Various structures can be employed.
[0011]
In this joint structure, the upper end surface or the lower end surface of the column is brought into contact with the lower surface or the upper surface of the beam, and a bending moment and a large bearing force (force in a direction perpendicular to the joint surface) are applied to the joint surface. It acts, and a large shear force (force in a direction parallel to the joint surface) does not act. Therefore, the central portion of the column is directly in contact with the beam to transmit a large vertical force. On the other hand, the column fixing brackets fixed to both side ends transmit the compressive force and the tensile force generated in the axial direction of the column when a bending moment is applied to the beam, and the column fixing bracket and the column fixing bracket The force acting on the part that fixes the wooden pillar is kept small. For this reason, the column fixing bracket and the mounting portion thereof can have a simple structure.
[0012]
Further, the column fixing bracket is connected to a screw member screwed into the beam, and the compressive force and the tensile force in the axial direction of the column are transmitted to the beam via the screw member. At this time, the screw member penetrates in the vertical direction of the wooden beam, that is, the direction perpendicular to the grain, and has an effect of reinforcing the beam. Then, the force is transmitted to the beam in a wide range in the cross section of the beam via the screw member, so that stress is less concentrated in the beam and the bending moment is transmitted smoothly.
[0013]
The invention according to claim 2 is the column-beam joint structure according to claim 1, wherein the column fixing bracket opposes a first plate portion abutted on the wooden beam and the first plate portion. And two second plate portions vertically raised from two sides, wherein the first plate portion has a bolt hole, and the screw member is formed by a column fixing bolt inserted through the bolt hole. And the second plate portion is connected to the wooden column by a plurality of pins or bolts that penetrate the wooden column in a horizontal direction.
[0014]
In this joint structure, the column fixture has two substantially parallel second plate portions, and force is transmitted to and from the column via the second plate portions. In addition, a supporting force and a large shearing force act on a pin or a bolt for fixing the column fixing bracket to the column, but are dispersed by the presence of two second plate portions, thereby reducing the number of pins or bolts. It is also possible.
Further, the first plate portion is connected to one screw member by one bolt, and when the member size in the thickness direction of the pillar and the beam (the direction perpendicular to the plane including the respective axes) is small. In addition, a large cross-sectional defect is not caused by penetrating the screw member.
[0015]
The invention according to claim 3 is the column-beam joint structure according to claim 2, wherein the wooden column is parallel to the side surface between two opposing side surfaces of the wooden column at a position where the column fixing bracket is attached. It has two slits, and it is assumed that the second plate portion is inserted into and connected to the slit.
[0016]
In this joint structure, since the second plate portion of the column fixing bracket is inserted and coupled into the slit provided in the column, the column fixing bracket is not exposed on two opposing surfaces of the column. Therefore, this surface can be directly displayed in the living room and used as an interior surface.
[0017]
The discovery according to claim 4 is the column-beam joint structure according to claim 2 or 3, wherein the screw member is screwed such that an end surface is inside the surface of the wooden beam, and the screw member is inserted from the end surface. It is assumed that a screw hole is provided in the axial direction of the column, and the first plate portion of the column fixing bracket is connected by a bolt screwed into the screw hole.
[0018]
In this joining structure, the column fixing bracket can be easily joined by screwing a bolt into a screw hole provided on the end face of the screw member. And since the end face of a screw bolt is inside the lower surface or upper surface of a wooden beam, if it tightens the said bolt strongly, it can join in the state which pressed the end surface of the pillar strongly to the lower surface or upper surface of a beam. Thereby, high rigidity is maintained at the joint between the column and the beam.
[0019]
The invention according to claim 5 is the column-beam joint structure according to claim 2, wherein the column fixing bracket connects two opposing second plate portions to prevent buckling of the second plate portions. Bolts that restrain the spacing between them.
[0020]
When a large bending moment acts between the column and the beam, a large compressive force in the axial direction of the column acts on one of the column fixing brackets provided at both ends in the column width direction. If the compressive force exceeds a certain limit, the second plate portion may buckle. However, by connecting the two second plate portions with bolts, lateral displacement of the second plate portion is restrained, and buckling is effectively prevented.
[0021]
The invention according to claim 6 is the column-beam joint structure according to claim 1, wherein the screw member is provided with a screw hole or a through hole in a direction perpendicular to the axis on a side portion, and is screwed into the screw hole. It is assumed that the wooden beam is joined to another wooden beam by a bolt or a bolt inserted into the through hole.
[0022]
In this joint structure, another beam is joined to the beam joined to the column, and a shearing force acting between these two beams, that is, a vertical force is transmitted to the screw member via the bolt. The vertical force transmitted to the screw member is transmitted from the peripheral surface of the screw member to the beam in which the screw member is embedded, and is also transmitted from the screw member to the pillar. Therefore, even if a large shearing force is applied from another beam to the joint between the column and the beam, the force is smoothly transmitted, and a large local stress is rarely generated. In addition, the column and the beam and the beam and the beam can be joined by also using the screw member, and the structure of the joint of the three members can be simplified.
[0023]
The invention according to claim 7 is the column-beam structure according to claim 6, wherein the wooden beam (first wooden beam) is formed by a bolt screwed into the screw hole or a bolt inserted into the through hole. A beam joint is fixed to the side surface, and the beam joint is provided substantially perpendicular to the first joint plate that is in contact with the side surface of the first wooden beam. A second joining plate portion, wherein the first joining plate portion is fixed to the first wooden beam by the bolt, and the second joining plate portion is connected to another wooden beam (second wooden beam). Beam) is fixed to the second wooden beam by a pin or bolt penetrating the beam in the horizontal direction.
[0024]
The beam joint is attached to a side surface of the beam into which the screw member is screwed, and a vertical force acting on the beam joint is transmitted to the screw member via a bolt. On the other hand, a force in the vertical direction is transmitted from another beam to be joined to the beam via a pin or a bolt penetrating the other beam to the beam joining fitting. Therefore, the force acting between the two beams is transmitted from the pin or the bolt via the column joint fitting, the bolt fixing the column joint fixture, and the screw member, and can be surely generated without causing mutual displacement or the like at the joint. Power is transmitted.
[0025]
The invention according to claim 8 is the column-beam joining structure according to claim 1, wherein the screw member has a column fixing bracket having a lower end fixed to an upper end of a column joined to a lower surface of the wooden beam. It is assumed that the upper end is connected to a column fixing bracket fixed to the lower end of a column joined to the upper surface of the wooden beam.
[0026]
In this joint structure, both a pillar that supports the beam from below and a pillar that stands on the beam are connected to the two screw members screwed into the beam. Then, the force is smoothly transmitted between the beam and both columns via the screw member. Further, the two columns joined to the upper and lower sides of the beam are connected via a screw member and have high rigidity like a continuous column despite being separated by the beam.
[0027]
BEST MODE FOR CARRYING OUT THE INVENTION

FIG. 2 shows the axis of the rigid frame structure. FIG. 3 shows a cross section in a direction perpendicular to the plane including the plane, and FIG. 3 shows a cross section parallel to the axis of the rigid frame structure. FIGS. 4, 5 and 6 are exploded perspective views of the same joint structure.
In this joint structure, two screw members 11 screwed into the beam 2 and two column fixing brackets 12 fixed to columns are connected by bolts 13, and the two column fixing brackets 13 are attached. The upper surface 1a of the pillar is in direct contact with the lower surface of the beam 2 between the positions.
[0030]
As shown in the side view and the front view in FIG. 7, the screw member 11 is provided with a spiral projecting portion 11a on the side surface of a rod-shaped steel member. 11b is provided. As shown in FIG. 5, the screw member 11 is provided with two through holes 2a in the beam 2 at a predetermined interval in the vertical direction, and further screwed after cutting a spiral groove. The length of the upper and lower end faces of 11 is set to be inside the member from the upper and lower faces of the beam.
[0031]
As shown in FIG. 6, the column fixing bracket 12 includes a first plate portion 12a facing the lower surface of the beam 2 and two second second portions raised in parallel from two opposite sides of the first plate portion 12a. And a through hole 12c through which the bolt 13 is inserted is provided at the center of the first plate portion 12a. For the first plate portion 12a, a steel plate having a sufficient thickness so as not to cause bending deformation is used. Further, a plurality of holes 12d through which the pins 14 are inserted are provided in the second plate portion 12b.
[0032]
On the other hand, as shown in FIG. 6, notches 1b are provided at both ends in the column width direction (axial direction of the beam) at the upper end of the column 1, and the notches 1b are parallel to the axial direction of the column. Two slits 1c are provided. The second plate portion 12b of the column fixing bracket is inserted into the slit 1c, and the pin 14 inserted from the vertical surface of the column penetrates the column 1 and is inserted into the hole 12d of the second plate portion 12b. The column fixing bracket 12 is fixed to the column 1.
[0033]
The upper surface of the first plate portion of the column fixing bracket 12 is fixed to the column fixing bracket 12 so as to substantially coincide with or slightly lower than the upper end surface 1a of the column, and the bolt 13 inserted into the through hole 12c is provided. Is screwed into a screw hole 11b provided at an end of the screw member 11, whereby the column fixing bracket 12 and the screw member 11 are joined, and the column 1 and the beam 2 are joined.

Thus, the vertical force is transmitted while the column 1 and the beam 2 are constantly pressed against each other. In addition, the bending moment acting on the joint portion is controlled by the pulling force transmitted from the screw member 11 to the column 1 via the bolt 13 and the column fixing bracket 12 and from the screw member 11 via the column fixing bracket 12 to the column 1. And the joint is maintained at a high rigidity.

When a bending moment acts on the column-beam joint, one of the column fixing brackets 12 is subjected to an upward tensile force from the bolt 13 to the first plate portion 12a, and the other is a screw member 11 or a beam. A downward compressive force acts on the first plate portion 12a from the lower surface of the second member 12. When an upward tensile force is applied, bending deformation occurs in the first plate portion 12a. However, by using a thick steel plate for the first plate portion 12a, it is possible to resist bending moment. On the other hand, when a compressive force acts, a large compressive force acts on the second plate portion 12b. Since the second plate portion 12b is made of a thin steel plate to be inserted into the slit 1c, There is a possibility that bending may occur. In such a case, as shown in FIG. 8, the second plate portion 12b is connected with the bolt 15 and the nut 16 at the upper part of the column fixing bracket 12, and the second plate portion 12b is deformed to the side. Can be restrained. As a result, the compressive force that causes buckling can be significantly increased, and buckling can be effectively prevented.

When the column 3 is also joined to the beam 2 so as to be able to transmit a bending moment and a two-layer frame structure is formed, as shown in FIG. Partial columns 3 can be joined to the beam 2. At this time, the screw member 11 penetrating the beam 2 can be used in common with the one used for joining the columns 1 on the first floor. As a result, the pillar 1 on the first floor and the pillar 3 on the second floor are connected via the screw member 11, and both pillars have rigidity close to that of the through pillar.
[0036]
In addition, the pillar 3 of the second floor is not limited to the one that is erected at the same position as the pillar 1 of the first floor as described above, and can be erected at a completely changed position. It is also possible to use only one of the two screw members 11 in common and to stand up at a slightly shifted position.
