【発明の属する技術分野】
本発明は、木材や集成材同士、又は、木材と石材やコンクリートとを接合する接合具、及びそれを用いて柱，梁，桁、まぐさ等が木材や集成材等からなる木造建築物の構造部材同士を確実に接合して固結し、木造建築物の耐震性を向上するとともに、耐力壁や筋交いを不要にすることも可能にし、更に、増築や既存建屋の耐震補強もできる構造部材の接合構造、並びに、構造部材を簡単かつ確実強固に接合できる構造部材の接合方法に関するものである。
【０００２】
【従来の技術】
従来から、日本では、南面に大きな開口を設けたり、広縁や二間続きの和室等の続き間、大きな床の間、等の開放的な間取りを設けた和風住宅や数寄屋風住宅が多く建築されている。
一方、最近では、敷地の狭い都会地での木造３階建て住宅の着工数も増加しており、土地柄、敷地が狭いため１階に車庫を設けることを要求され１階に大きな間口を要すものも多く建築されている。
以下、１階に車庫を設けた３階建ての住宅の一例について、図面を用いて説明する。
図１１（ａ）は３階建て住宅の１階平面図であり、図１１（ｂ）は３階建て住宅の２階平面図であり、図１１（ｃ）は３階建て住宅の３階平面図である。
図中、１００ａ，１００ｂは柱、１０１は柱１００ｂ間に配置された耐力壁、１０２は車庫、１０２ａは車庫１０２の開口した間口である。
図１１の３階建て住宅では、車庫１０２の間口１０２ａを要すため柱１００ａ間には柱１００ｂ間のように、耐力壁１０１を配置することができないとともに、車庫１０２の上方に２階と３階の荷重がかかるため、従来から、柱１００ａに大型の構造部材を使用したり、１階だけを鉄骨構造やＲＣ構造にしたりしている。
【０００３】
また近年では、これらの住宅等の建築において、建築時の省力化、合理化又は木造建築物の強度の向上を目的として、接合具や金具、箱金物等を用いた仕口や継手等により、梁と桁，柱と梁，胴差と通し柱等を接合する構造部材の接合構造や接合方法が開発されている。
また、阪神大震災を含め毎年、地震や台風等で特に木造住宅が大きな被害を被ることが多く、木造建築物の各構造部材同士の接合構造において、仕口等の接合部分の強度向上を含めて建築物全体の構造強度の向上を図った構造部材の接合構造や接合方法が種々開発されている。
【０００４】
例えば、実開昭６３−８６４１１号公報（以下、イ号公報という）には、ボルトの一端に開口する中心孔とこの中心孔とボルト側面とを連通する横孔とからなる硬化性樹脂接着剤注入路を有する木材組立用ボルトが開示されている。
【０００５】
実開平５−３８４１２号公報（以下、ロ号公報という）には、集成材を締結すると共に締結用のボルト孔の隙間内に接着剤を導入するためのボルトであって、該ボルトは、その軸部の外周に接着剤を流通させる凹部を形成すると共にその頭部に凹部に連通して外方側に開口する少なくとも２個の貫通路を形成した接着剤注入ボルトが開示されている。
【０００６】
特開平６−１０４１９号公報（以下、ハ号公報という）には、少なくとも２つの被連結材に共通の継手を嵌挿するようにして、被連結材を衝合させるとともに、被連結材に設けられたボルト孔と、継手に設けられたボルト孔とにボルトを貫通させ、該ボルトをナットにて締結固定する骨組みの連結機構において、ボルトには、ボルト締め付け時に外部に開口する一方の開口部と、ボルト孔に開口する他方の開口部とを有する連通路が設けられ、該連通路を通して少なくとも継手のボルト孔と、ボルトとの間隙に充填剤が充填される骨組みの連結機構が開示されている。
【０００７】
【発明が解決しようとする課題】
しかしながら、上記従来の接合具や構造部材の接合構造，接合方法では、以下の課題を有していた。
木造建築物の構造部材の接合に金具や金物等を用いた場合、構造部材に金具や金物等を装着するとともに、これにボルトやナット等を介して構造部材同士を固定せねばならず、施工作業性に欠けるとともに、施工時の作業が煩雑で作業性に欠け、また、木材の伸縮により数年で固定力が低下しガタが生じ易く接合強度の信頼性に欠ける。構造部材の接合部分には、曲げや引張り、圧縮、剪断等の物理的強度を要するため、構造部材の接合に使用される金具や金物等が大型になり、重量があり運搬性に欠け、特に高所作業での安全性に欠ける。
木材からなる構造部材同士をボルトやナットで固定した場合、木材の伸縮により数年で締付力が低下しガタが生じ易いとともに、ボルトやナット、金物等の金属部分の酸化により物理的強度が低下し信頼性や耐久性に欠けるという課題を有していた。
【０００８】
従来の接合構造では、構造部材の接合部分がピン接合になっているため、木造建築物の強度が不十分で、筋交い、構造用合板、鋼製ブレース等を要し、しかも、地震時等には筋交いが折れたり外れたりして本来の役目を果たさないことがあり、信頼性に欠ける。
また、開放的な間取りを有した和風住宅や数寄屋風住宅等の場合、大きな開口や広縁，和室の続き間等の開放的な間取りになっている部分では、筋交いや耐力壁を設けることができず、筋交いや耐力壁の配置が偏り、建物の重心と耐力壁の中心の剛心が離れ、地震等の場合に建物自体が大きな揺れを生じ建物が倒壊する傾向が高く、建物の剛性や耐震性，安全性に欠けるという課題を有していた。
【０００９】
また、図１１に示すような３階建ての住宅では、１階に車庫１０２を設けているため、柱１００ａ間に耐力壁を配置することができないとともに、車庫１０２の上方に２階，３階の荷重がかかり、地震の際には、車庫１０２の柱１００ａから破壊される可能性が高く、耐震性や安全性に欠ける。更に、車庫１０２の間口１０２ａに耐力壁１０１が形成できないため、地震や２階乃至３階の振動で住宅全体が揺れ易く、その際、特に、３階の壁のクロスが歪んだり破れたりする可能性が有る。更に、柱１００ａに大型の構造部材を使用したり、１階だけを鉄筋構造にした場合、建築の手間がかかり建築施工性に欠けるとともに、コスト高を引き起こすという課題を有していた。
【００１０】
更に、イ号乃至ハ号公報では、以下の課題を有していた。
イ号乃至ハ号公報では、いずれも、部材（被連結材）同士をボルト・ナットで連結した後に、ボルトに形成された接着剤が注入（流通）される孔や凹部を介して、ボルトの外周面とボルトを挿通したボルト孔との間に接着剤を充填し部材同士を接合しているので、ボルトが挿通されるボルト孔が、連結する部材同士に貫通されていなければ部材同士を連結（接合）することができず、そのため、例えば、梁と柱等の接合にイ号乃至ハ号公報のボルト・ナットは使用できず、汎用性や使用性に欠ける。
また、梁と柱を接合する場合、ハ号公報のように、被連結材に共通の継手を嵌挿し被連結材を衝合させた後、ボルト・ナットで被連結材同士を接合しなければならず、ボルト・ナットの他に「継手」部材が必要となり、部品点数が増え取扱性や部材の接合作業性に欠ける。
【００１１】
本発明は上記従来の課題を解決するもので、簡単な構造でかつ接合作業性に優れ施工期間を著しく短縮できるとともに、構造強度の高い接合具の提供、及び、木造建築物の構造強度を向上できるとともに、増築や既存建屋の耐震補強もでき、耐震性や安全性に優れ、また、施工作業時の安全性に優れるとともに、汎用性に優れ未熟練者でも簡単かつ確実に接合強度に優れた接合ができる構造部材の接合構造、並びに、施工作業性を著しく向上できるとともに、構造部材の接合技術を単純化し作業工数を削減でき、施工期間を著しく短縮することができる構造部材の接合方法を提供することを目的とする。
【００１２】
【課題を解決するための手段】
上記従来の課題を解決するために本発明における接合具及びそれを用いた構造部材の接合構造並びに構造部材の接合方法は、以下の構成を有している。
本発明の請求項１に記載の接合具は、ａ．中実棒状の胴部と、ｂ．前記胴部の一端部側に前記胴部の軸心と略直角に貫通された貫通孔と、ｃ．前記胴部の他端部側に形成された雄螺子部と、ｄ．前記胴部の略軸心の長手方向に形成された中空部と、ｅ．前記雄螺子部側の前記胴部の端面から前記中空部に連通した接着剤の注入口と、ｆ．前記胴部の外周面から前記中空部に連通して穿設された１乃至複数の接着剤の吐出口と、ｇ．前記雄螺子部に螺着されるナットと、ｈ．前記貫通孔に挿着される胴部固定部材と、を備えた構成を有している。
【００１３】
これにより、以下の作用を有する。
（１）該接合具が、貫通孔，雄螺子部，中空部，注入口，吐出口を有した棒状の胴部と、ナットと、胴部固定部材とからなり、該接合具の構造や形状が単純で加工性に優れ、該接合具の生産性を向上できる。
（２）木材間や集成材間若しくは木材と集成材同士、又は、木材と石材やコンクリート等の部材同士を接合する際に、接合する部材に挿入部を形成して接合具を挿入部に挿入し、部材の外周壁部側から接合具の貫通孔に胴部固定部材を挿着し、胴部の雄螺子部にナットを螺着するだけで、該接合具で部材同士を容易に接合することができる。
（３）接合具の胴部の長手方向に中空部を備えているとともに、中空部に連通して穿設された接着剤の吐出口を備えているので、注入口から中空部に接着剤を注入することにより吐出口から接合具の胴部の外周面及び接合具が挿入された部材の挿入部の周壁間に接着剤を充填することができ、部材同士を確実に固結して剛接合することができる。
（４）複数の接合具を用いて部材同士を接合する場合、接合具の胴部の外径を小さくすることができ、部材の断面欠損を減少させ部材の強度の低下を防止することができる。
（５）部材に形成された接合具を挿入する挿入部に金属製等の高強度部材からなる接合具が接着剤で埋設固定されるので、高剪断，高張力の剛接合を維持することができ、また、接合具の胴部が貫通孔に挿着された胴部固定部材で挿入部内に固定されるので、胴部固定部材の剪断力や靱性により部材同士の接合強度を向上できる。
（６）部材に形成された挿入部に接合具を挿入し、部材の外周壁部側から接合具の貫通孔に胴部固定部材を挿着し、胴部の雄螺子部にナットを螺着することにより、部材同士を引き寄せて部材同士の当接面を密着させることができ、部材同士の当接面から接着剤が漏れるのを防止でき、部材同士を確実に密着して接合できる。
（７）特に、柱とまぐさを接合する際に、柱の外周壁部からまぐさに連通して形成された挿入部に接合具を挿入し、まぐさの外周壁部から接合具の貫通孔に胴部固定部材を挿着して胴部の雄螺子部にナットを螺着した後、注入口から中空部へ接着剤を注入するだけで、柱とまぐさを強固に接合することができ、柱間の開口部の耐力を向上することができるとともに、水平力による軸組の変形を防止できる。
【００１４】
ここで、接合具の胴部としては、断面を円形状に形成する他、略楕円形状，三角形や四角形，六角形等の略多角形状等、任意の形状に形成してもよい。
接合具の材質としては、ステンレス鋼，クロム，鉄鋼，カーボン鉄鋼等の鉄製品やアルミニウム合金等の金属製の他、カーボン繊維やボロン繊維，ガラス繊維，金属繊維等の有機や無機の繊維と合成樹脂で成形加工したものが用いられる。
【００１５】
接合具の貫通孔としては、胴部の外径の０．３倍〜０．８倍の大きさで形成するのが好ましい。尚、貫通孔が胴部の外径の０．３倍より小さくなるにつれ、貫通孔に挿着される胴部固定部材の外径も小さくなり、胴部固定部材の剪断力が低下し接合具を部材に挿着した際の剛性が低下する傾向があり、また、貫通孔が胴部の外径の０．８倍より大きくなるにつれ、胴部に形成される貫通孔が大きくなるため胴部の剪断力が低下し胴部の強度が低下する傾向がある。
【００１６】
接合具の中空部及び中空部に連通した接着剤の吐出口や注入口としては、接合具の胴部の外径の約１／２０倍〜１６／２０倍、好ましくは約１／１０倍〜５／１０倍の大きさの直径を有した、断面が略円形状に形成される。尚、接着剤の粘性や接合具の材質にもよるが、直径が接合具の胴部の外径の１／１０倍より小さくなるにつれ中空部内での接着剤の流動性に欠け接着剤の注入に時間がかかる傾向があり、また、５／１０倍より大きくなるにつれ接合具の機械的強度が損なわれる傾向がある。
【００１７】
吐出口としては、中空部に連通して接合具の胴部の直径方向に形成される。また、吐出口を２以上形成する場合は、中空部に連通するとともに接合具の胴部の直径方向に貫通して形成してもよく、また、中空部を中心に略放射状に形成してもよい。尚、吐出口を２以上形成した場合、中空部に注入された接着剤が複数の吐出口から吐出されるので、接着剤の注入時間を短縮することができる。更に、中空部から対称の位置に吐出口を形成すると、中空部に注入された接着剤を接合具の外周面に略均等に吐出することができ、接着剤の充填ムラを防止できる。
吐出口の形成位置としては、接合具を部材の上面から下方に傾斜して挿入する場合、吐出口を接合具の胴部の貫通孔側に形成し、接合具を部材の下面から上方に傾斜して挿入する場合、吐出口を接合具の胴部の雄螺子部側に形成するのが好ましい。これにより、接合具の外周面及び接合具が挿入された部材の挿入部の周壁間に接着剤を満遍なく充填することができる。
胴部固定部材としては、貫通孔に応じて貫通孔に挿着できる大きさに形成され、棒状体のピンや釘，ラグスクリュー，コーチスクリュー等のネジ等が用いられる。尚、市販の釘やネジ等を用いた場合、該接合具の低コスト化を図ることができる。
【００１８】
また、部材同士をコの字状の箱金物やフック状の金物等の従来の接合金具で接合した後に、各部材に挿入部を形成して該接合具を挿入し、部材の外周壁部側から接合具の貫通孔に胴部固定部材を挿着して雄螺子部にナットを螺着し、接合具の中空部に接着剤を注入して部材同士を固結してもよい。この場合、接合金具で部材同士を仮固定した後に部材同士を接合でき部材の接合作業性を向上できるとともに、接合精度を向上でき、また、部材同士の当接面を密着して接着剤の漏れを防止でき、また、接合金具に加えて該接合具で部材同士の剪断，張力等の接合強度を維持することができるとともに、接合金具と該接合具を併用することにより該接合具の小型化を図ることができ、更に、地震等で接合金具と該接合具のいずれか一方が万が一破損した場合にも建築物が完全に破壊されるのを防止できる。
【００１９】
本発明の請求項２に記載の接合具は、請求項１に記載の発明において、前記胴部の前記雄螺子部側の端部及び／又は前記ナットに形成又は配設された接着剤流出防止部を備えた構成を有している。
【００２０】
これにより、請求項１の作用に加えて、以下の作用を有する。
（８）接着剤流出防止部を備えているので、部材に形成された挿入部の開口部側を接着剤流出防止部で塞ぐことができ、挿入部の周壁と挿入部に挿入された接合具の胴部の外周面との間に接着剤を充填した際に、挿入部の開口部側から接着剤が流出するのを防止できる。
【００２１】
ここで、接着剤流出防止部としては、胴部の雄螺子部側の端部に挿入部の外径よりも大きく形成されたツバ部からなるもの，ナットの部材の外周壁部と当接する側に挿入部の外径よりも大きく形成されたツバ部からなるもの，胴部に外嵌されナットと部材との間に配設される座金からなるもの等、挿入部の開口部の外径より大きく形成されナットと部材の外周壁部との間で挿入部の開口部側を塞ぐことができる形状のものが用いられる。
【００２２】
本発明の請求項３に記載の接合具は、請求項１又は２に記載の発明において、前記胴部が、一端に前記雄螺子部を有し他端に接合部を有した頭部部材と、両端に胴接合部を有した１又は２以上の胴部材と、一端に接合部を有し他端側に前記貫通孔を有した先端部材と、を備えた構成を有している。
【００２３】
これにより、請求項１の作用に加えて、以下の作用を有する。
（９）頭部部材と胴部材，先端部材を順に各接合部で接合して連結することにより、該接合具を容易に形成することができ、また、接合する胴部材の数により接合具の長さを任意に変更することができる。
（１０）特に、吐出口が該接合具の貫通孔側に形成される場合、頭部部材と胴部材，先端部材の各々に中空部を形成し、先端部材の中空部に連通した吐出口を先端部材に形成することにより中空部や吐出口を形成することができ、該接合具の中空部を各部材毎に分割して形成することができるので、各中空部の形成距離を短くでき、接合具の貫通孔側に吐出口を形成する場合にも容易に中空部や吐出口を形成することができる。
【００２４】
ここで、接合部や胴接合部としては、雌螺子部又は雄螺子部を形成したもの、嵌合凹部又は嵌合凸部を形成したもの等、各部材が脱着自在に接合できる形状のものが用いられる。また、頭部部材と先端部材を各接合部で接合して該接合具を形成してもよい。
また、中空部は、各部材を連結した際に該接合具の長さ方向で略一直線になるように吐出口まで形成される。
尚、接合具の胴部に形成される吐出口が貫通孔側に形成される場合、胴部に形成する中空部の距離が長くなり、また、中空部の形成距離が長すぎる場合には中空部の形成が不可能になるため、吐出口が貫通孔側に形成される場合に、頭部部材，胴部材，先端部材に分割された該接合具が好適に用いられる。
【００２５】
本発明の請求項４に記載の接合具は、請求項１乃至３の内いずれか１項に記載の発明において、前記胴部の外周面が螺子状又は異型鉄筋状の凹凸面に形成された構成を有している。
【００２６】
これにより、請求項１乃至３の作用に加えて、以下の作用を有する。
（１１）接合具の注入口から中空部に接着剤を注入して吐出口から接合具の胴部の外周面及び接合具が挿入された部材の挿入部の周壁間に接着剤を充填した際の、胴部と挿入部との接着効果を向上することができ、該接合具と部材との接着力を向上できる。
【００２７】
ここで、該接合具の胴部としては、外周面に螺旋状の凹凸面を形成したものや、所定間隔毎に外周面に凸条部や凸部又は凹条部や凹部を形成したもの等が用いられる。また、胴部として、外周面が螺子状に形成されたボルト鋼や、外周面に凸条や凸状のリブや節を有した異型鉄筋（異型棒鋼）等を用いてもよい。更に、胴部全長の外周面に凹凸面を形成してもよく、胴部全長に所定間隔で凹凸面を形成してもよく、また、胴部の両端部側や胴部の長さ方向の中央部等、胴部の一部に凹凸面を形成してもよい。
【００２８】
本発明の請求項５に記載の接合具は、請求項１乃至４の内いずれか１項に記載の発明において、前記胴部に外嵌されたスプリング等の螺旋状部材を備えた構成を有している。
【００２９】
これにより、請求項１乃至４の作用に加えて、以下の作用を有する。
（１２）接合具の中空部に接着剤を注入した際に、接合具の吐出口から吐出される接着剤を接合具の外周面及び接合具が挿入された部材の挿入部の周壁間で螺旋状部材に沿って略均等に充填することができ、接着剤のショートパスを防ぎ、接着剤の充填ムラが生じることを防止でき部材同士を確実に固結でき、また、粘度の大きい接着剤も容易にムラなく充填することができる。
（１３）接合具の胴部に螺旋状部材を外嵌しているので、部材の挿入部に接合具とともに螺旋状部材を接着剤で埋設固定することができ、その結果、該接合具の耐久性を向上でき接合具を補強材として使用することもでき、部材同士の接合部分の剪断，引張り応力等を向上できる。
【００３０】
本発明の請求項６に記載の接合具は、請求項１乃至５の内いずれか１項に記載の発明において、前記注入口に嵌合される突起部を有した封止体を備えた構成を有している。
【００３１】
これにより、請求項１乃至５の作用に加えて、以下の作用を有する。
（１４）注入口から中空部へ接着剤を注入した後、注入口に封止体の突起部を嵌合して注入口を封止することができ、特に、粘度の極めて低い接着剤や硬化に長時間を要す接着剤を中空部へ注入した場合でも、接着剤が硬化する前に注入口から接着剤が漏れるのを防止でき、部材同士を確実に固結することができる。
（１５）封止体で注入口を封止することができるので、雄螺子部側（注入口側）の胴部の端面及び雄螺子部に螺着されたナットの端面を封止体で覆うことができ、部材の挿入部の外観を向上できる。
【００３２】
ここで、封止体としては、注入口に嵌合できる突起部を有していればよく、接合具の注入口側（雄螺子部側）端部及び雄螺子部に螺着されたナットの端面を覆設できる形状のものや、突起部を注入口に嵌合した際に該接合具が挿入された部材表面と面一になるように形成されたもの等が用いられる。
【００３３】
本発明の請求項７に記載の構造部材の接合構造は、請求項１乃至６の内いずれか１項に記載された接合具と、所定の当接面で当接される横架構造部材や縦構造部材等の２以上の構造部材と、前記構造部材の外周壁部から前記当接面に対して直交若しくは所定の傾斜角度を有して他の前記構造部材と連通して穿孔された１以上の接合具挿入部と、当接される前記構造部材の内いずれか１の前記構造部材の外周壁部から前記接合具挿入部に略直交して穿孔された固定部材挿入部と、前記接合具の中空部に注入されて前記接合具の吐出口から吐出され前記接合具の外周面と前記接合具挿入部の周壁間に充填される接着剤と、を備えた構成を有している。
【００３４】
これにより、以下の作用を有する。
（ａ）２以上の構造部材に連通して穿孔された接合具挿入部に接合具を挿入するとともに、固定部材挿入部から接合具の貫通孔に胴部固定部材を挿着し、接合具の雄螺子部にナットを螺着することにより、構造部材同士を接合具で接合することができる。
（ｂ）接合具の注入口から中空部に接着剤を注入することにより、接合具の吐出口から接着剤を吐出して、接合具の外周面と接合具挿入部の周壁間に接着剤を充填することができ、構造部材同士を固結することができる。
（ｃ）機械的強度が著しく高い接合具を各構造部材に埋設して構造部材同士を確実に固結して接合しているので、構造部材の曲げ，引張り，圧縮，剪断等に対する抵抗力を向上でき、また、接合具を接合具挿入部に胴部固定部材で固定しているので、胴部固定部材の剪断力により構造部材の接合強度を向上できるとともに、胴部固定部材の靱性により構造部材同士の接合部分の靱性を向上できる。
（ｄ）接合具を構造部材の当接面に対し所定の傾斜角度を有して挿入した場合、鉛直荷重に対する変形に耐えることができ、構造部材同士の剛性を向上できる。
（ｅ）構造部材間でクロス状になるように接合具挿入部を形成した場合、接合具を接合具挿入部に挿入するだけで構造部材同士を連結，保持することができ構造部材同士の接合が容易にでき、また、接合具を胴部固定部材とナットで構造部材に固定して接着剤を注入すると、構造部材の上下左右からの荷重を各接合具の偶力で打ち消すことができ、極めて機械的強度に優れた接合を可能にすることができる。
（ｆ）接合具が構造部材に埋設されるとともに、接合具の外周面が接着剤で被覆されるため、接合具が酸化等するのを防止でき、接合具の耐久性を向上することができる。
（ｇ）接合具を構造部材の接合具挿入部に挿着して構造部材同士を接合し、更に、接合具の外周面と接合具挿入部の周壁間に接着剤を充填して構造部材同士を固結しているので、構造部材同士を剛接合することができ、接合強度を向上でき、また、接着剤で固結しているので、木材等の構造部材の伸縮を吸収できガタつきを防止できる。
（ｈ）構造部材同士の接合部分が、接合具と接着剤で強固に接合されたラーメン構造となるので、耐力壁や筋交いを使用することなく建築物の間口（スパン）を著しく広げることができ、柱の無い空間を得ることができる。
【００３５】
ここで、接合具挿入部の長さ（全長）としては、接合具の胴部の全長よりナットの締め代分（ナットを雄螺子部に螺着できる長さ）だけ短く形成（接合具挿入部に接合具を挿入した際に雄螺子部のナットが螺着される部分が、接合具挿入部の開口側から突出する長さで形成）される。尚、接合具を接合具挿入部に挿着した際に、接合具の貫通孔側の端部が接合具挿入部の底部側に当接しないのが好ましい。これにより、接合具の貫通孔側の端部と接合具挿入部の底部との間にも接着剤を充填することができるとともに、接合具の外周面と接合具挿入部の周壁間の全体に接着剤をスムーズに充填することができ、接着剤の充填ムラを防止でき構造部材同士を確実に固結できる。
【００３６】
接合具挿入部は、構造部材の大小にもよるが、構造部材の外周壁面から内側に接合具の胴部の外径の１．１倍〜６倍の位置に形成される。接合具挿入部が、構造部材の外周壁面から接合具の胴部の外径の１．１倍より小さい位置になるにつれ構造部材に大きな外力がかかった際に構造部材の端部や表面が破損する傾向が有り、６倍より大きい位置になるにつれ構造部材に形成できる接合具挿入部の数が減少し構造部材同士の接合力を向上させ難い傾向が有る。
また、接合具挿入部の大きさとしては、接合具の胴部の外径より３ｍｍ〜１５ｍｍ、好ましくは４ｍｍ〜１２ｍｍ大きく形成される。構造部材の材質や接着剤の種類等にもよるが、接合具挿入部と接合具の胴部の外径との差が４ｍｍよりも小さくなるにつれ、接着剤の種類や施工時期（夏期，冬期）にもよるが、吐出口から吐出された接着剤が接合具の胴部の外周面と接合具挿入部の周壁間で流動し難くなる傾向が有り、接合具の胴部と外径との差が１２ｍｍよりも大きくなるにつれ必要以上に接着剤を要す傾向が有り、また、接合具の胴部と外径との差が３ｍｍよりも小さく若しくは１５ｍｍよりも大きくなるとこれらの傾向が更に強くなる。尚、接合具の胴部に螺旋状部材を外嵌し、接合具挿入部に接合具と螺旋状部材を挿入する場合は、螺旋状部材の外径や螺旋間隔等にもよるが、接合具挿入部に螺旋状部材を挿入できるとともに接合具の胴部と接合具挿入部の周壁間で接着剤を流動させることができる大きさ（例えば、螺旋状部材の外径より０ｍｍ〜１５ｍｍ大きい径）で接合具挿入部が形成される。
更に、接合具挿入部は円形や楕円形，四角形や六角形等の多角形状等任意の断面形状で形成される。

接合具挿入部としては、構造部材が水平片持ち梁等のように先端に特に大きな外力がかかる場合や登り梁等を接合する場合等は、傾斜角度αを有して形成するのが好ましい。傾斜角度αとしては、当接面に対して２０°≦α＜９０°好ましくは２０°≦α≦７０°より好ましくは３０°≦α≦６０°で形成される。構造部材の材質や接合具の大きさ等にもよるが、傾斜角度が３０°よりも小さくなるにつれ接合具挿入部の位置が構造部材の端部に近づき大きな外力に対して構造部材が破損し易くなる傾向が有り、傾斜角度が６０°よりも大きくなるにつれ接合具の長さが長くなりすぎて作業性が低下する傾向が有り、また、傾斜角度が２０°よりも小さくなるとこれらの傾向が更に強くなる。
【００３８】
特に、構造部材の上外周壁部側から接合具挿入部を形成した場合、該接合具を構造部材の上方から接合具挿入部に容易に挿着することができ作業性を向上できるとともに、構造部材の下外周壁部に接合具のナット等が露出するのを防止でき外観を向上でき、また、接合具の外周面と接合具挿入部の周壁間に確実に接着剤を充填できる。
また、接合する構造部材の当接面で所定間隔をあけて接合具挿入部とクロス状になるように他の接合具挿入部を穿孔し、各接合具挿入部に接合具を挿入して構造部材を接合した場合、接合した構造部材の引張り，曲げ，剪断等の上下左右からの荷重を各接合具の偶力で打ち消すことができ、構造部材同士の接合力を向上できる。
更に、接合具挿入部を傾斜角度αを有して形成若しくはクロス状に形成することにより、二方向ラーメン構造の場合や３，４方向に構造部材が有る場合にも、該接合具を用いて構造部材同士を接合できる。
【００３９】
固定部材挿入部としては、貫通孔と略同一径で形成される。また、固定部材挿入部を構造部材に貫通して形成、若しくは、接合具挿入部に連通して所定深さで形成してもよく、更に、胴部固定部材の一端部に頭部が有る場合、頭部が嵌合できるように固定部材挿入部の一端部側を大径に形成してもよい。更に、固定部材挿入部に胴部固定部材を挿着した後、固定部材挿入部の開口部に木栓等の込栓を打ち込み、構造部材の外周壁面と面一にしてもよい。これにより、構造部材の外観を向上できる。
尚、固定部材挿入部の軸心が接合具挿入部の軸心と直交するように形成するのが好ましい。これにより、接合具挿入部に挿入した接合具の貫通孔に固定部材挿入部から胴部固定部材を挿着した際に、接合具の軸心と接合具挿入部の軸心を略一致させて保持することができ、接合具の外周面と接合具挿入部の周壁間にムラなく接着剤を充填することができる。
接着剤としては、エポキシ樹脂系接着剤，ポリウレタン系接着剤，酢酸ビニル樹脂系接着剤等が用いられる。
【００４０】
本発明の請求項８に記載の構造部材の接合構造は、請求項７に記載の発明において、当接される前記構造部材の内いずれか１の前記構造部材の外周壁部から前記接合具挿入部に連通して穿孔された１乃至複数の空気抜き部を備えた構成を有している。
【００４１】
これにより、請求項７の作用に加えて、以下の作用を有する。
（ｉ）構造部材の種類（コンクリート等のように通気性がないものや集成材等のように通気性のあるもの）にもよるが、接合具の中空部に接着剤を注入する際に、中空部内や接合具挿入部内の空気が空気抜き部から排出されて、接着剤をスムーズに接合具の外周面と接合具挿入部の周壁間に充填できる。
（ｊ）接着剤注入時に空気抜き部から接着剤が溢れ出るのを確認することで、接合具の外周面と接合具挿入部の周壁間に接着剤が満たされたことを確認できる。
【００４２】
ここで、空気抜き部としては、接合具の吐出口から離れた位置に形成するのが好ましく、吐出口が接合具の胴部の貫通孔側に形成されている場合は接合具の胴部の注入口側、吐出口が接合具の胴部の注入口側に形成されている場合は接合具の胴部の貫通孔側、に形成される。これにより、接合具の外周面と接合具挿入部の周壁間に接着剤が充填される前に空気抜き部から接着剤が溢れ出るのを防止でき、確実に接合具の外周面と接合具挿入部の周壁間に接着剤を充填できる。また、空気抜き部は略円形や略楕円形，四角形等の多角形等任意の形状で、接着剤をスムーズに注入できる大きさで穿孔される。
また、空気抜き部から接着剤が溢れ出た後、空気抜き部の径が大きいときは木栓等の込栓を打ち込み、構造部材の外周壁面と面一にしてもよい。これにより、構造部材の外観を向上できる。
【００４３】
本発明の請求項９に記載の構造部材の接合構造は、請求項７又は８に記載の発明において、前記接合具挿入部の開口部に穿設され前記接合具挿入部と直交する１以上の座部を有し、前記座部の開口側を埋設し表面が前記構造部材の外周壁面と略面一に形成された埋設材を備えた構成を有している。
【００４４】
これにより、請求項７又は８の作用に加えて、以下の作用を有する。
（ｋ）胴部の雄螺子部に螺着したナットを座部に当接させることができるので、ナットが構造部材の表面から大きく突出するのを防止でき、構造部材の外観を向上できる。
（ｌ）座部の開口側に埋設材を埋設することにより、接合具のナットが構造部材の表面に露出するのを防止でき、特に、火災時等に構造部材の炭化皮膜により接合具を火災の高温から守ることができ安全性を向上することができる。
（ｍ）埋設材を構造部材の外周壁面と略面一にしているので、構造部材の外観を向上できる。
（ｎ）接合具のナットを埋設材で構造部材内に埋設しているので、接合具に外部の熱が伝わるのを防止でき、外部の熱が接合具を介して構造部材の内部に伝わるのを防止できる。
【００４５】
ここで、埋設材としては、接合具の注入口に挿入自在な突起部を有したものを用い、突起部を注入口に挿入して注入口を封止するとともに座部の開口側を埋設してもよい。
【００４６】
本発明の請求項１０に記載の構造部材の接合方法は、所定の当接面で当接される横架構造部材や縦構造部材等の２以上の構造部材に、請求項１乃至６の内いずれか１項に記載された接合具が挿入される接合具挿入部及び前記接合具挿入部に略直交し前記接合具の胴部固定部材が挿着される固定部材挿入部を形成する挿入部形成工程と、前記接合具挿入部に前記接合具を挿入し前記固定部材挿入部及び前記接合具の貫通孔に前記胴部固定部材を挿着する胴部挿着工程と、前記接合具の雄螺子部にナットを螺着し前記接合具を前記構造部材に固定するとともに前記構造部材同士を連結する固定工程と、前記接合具の中空部に接着剤を注入して前記構造部材を固結する固結工程と、を備えた構成を有している。
【００４７】
これにより、以下の作用を有する。
（ア）構造部材に接合具挿入部及び固定部材挿入部を形成し、接合具挿入部に接合具を挿入して固定部材挿入部と接合具の貫通孔に胴部固定部材を挿着した後、接合具の雄螺子部にナットを螺着するだけで、２以上の構造部材に接合具を固定して構造部材同士を連結することができ、構造部材の接合作業性を向上できる。
（イ）構造部材を順に組み立てていくことができ、建設現場で直接各構造部材の接合ができる。
（ウ）接合具を構造部材に固定した後、接合具の中空部に接着剤を注入するだけで、接合具の外周面と接合具挿入部の周壁間に接着剤を充填して構造部材同士を確実に固結することができ、構造部材の接合作業が簡単で作業性を向上できる。
【００４８】
ここで、接合具挿入部や固定部材挿入部としては、建設現場でドリル等で穿孔するか、又は、工場でプレカット方式等で予め形成してもよい。
尚、接合具挿入部に連通した空気抜き部や、接合具挿入部の開口部で接合具挿入部と直交した座部を形成する場合は、挿入部形成工程で接合具挿入部や固定部材挿入部とともに形成される。

【発明の実施の形態】
（実施の形態１，２）
本発明の実施の形態１における接合具について、以下図面を用いて説明する。
図１は実施の形態１における接合具の要部分解全体斜視図である。
図１において、１は実施の形態１におけるステンレス等の金属製の接合具、２は接合具１の断面が円形状の中実棒状の胴部、３は胴部２の一端部側に胴部２の軸心と略直角に貫通された貫通孔、４は胴部２の他端部側に形成された雄螺子部、５は胴部２の雄螺子部４側の軸心の長手方向に形成された中空部、６は雄螺子部４側の胴部２の端面２ａから中空部５に連通した接着剤の注入口、７は中空部５の端部と直交して胴部２の雄螺子部４側に穿設され中空部５と連通して対称位置に形成された接着剤の吐出口、８は胴部２の雄螺子部４側に外嵌される接着剤流出防止部の座金、９は雄螺子部４に螺着されるナット、１０は貫通孔３に挿着される棒状の胴部固定部材である。
ここで、実施の形態１では、貫通孔３は胴部２の外径の０．３倍〜０．８倍の大きさで形成されている。また、中空部５や注入口６，吐出口７は、胴部２の外径の１／１０倍〜５／１０倍の大きさの直径で断面略円形状に形成されている。
尚、接着剤流出防止部として座金８を胴部２の雄螺子部４側に外嵌する代わりに、胴部２の端面２ａに雄螺子部４の外径より大きな径のツバ部を形成してもよく、また、ナット９の端面にナット９の外径より大きな径のツバ部を形成してもよい。また、ナット９の外径が大きい場合は、接着剤流出防止部を備えなくてもよく、ナット９の端面を接着剤流出防止部としてもよい。
【００５０】
以上のように構成された実施の形態１の接合具１を用いて、以下、実施の形態２における木造建築物の構造部材の接合構造について、図面を用いて説明する。
図２は実施の形態２における構造部材間の仕口の接合構造を示す要部側面断面図であり、図３は図２のＡ−Ａ線断面図である。
図中、１１は柱等の縦構造部材、１２は桁等の横架構造部材、１３は筋交い等の構造部材、１４ａは縦構造部材１１と横架構造部材１２の当接面、１４ｂは縦構造部材１１と構造部材１３の当接面、１５，１６は縦構造部材１１の外周壁部から当接面１４ａ，１４ｂに対して直交して貫設され横架構造部材１２，構造部材１３の所定部に穿孔され穿孔部が連通して形成された接合具挿入部、１５ａ，１６ａは接合具挿入部１５，１６の底部、１７は横架構造部材１２，構造部材１３の上面又は側面の外周壁部から接合具挿入部１５，１６の底部１５ａ，１６ａ側に連通して穿孔された空気抜き部、１８は横架構造部材１２，構造部材１３の側面の外周壁部から接合具挿入部１５，１６に直交して接合具挿入部１５，１６の底部１５ａ，１６ａ側に横架構造部材１２，構造部材１３に貫通して穿孔された固定部材挿入部である。
【００５１】
ここで、実施の形態２では、接合具挿入部１５，１６は、接合具１の胴部２の外径より４ｍｍ〜１２ｍｍ大きな直径で形成されている。また、接合具挿入部１５，１６の開口部から底部１５ａ，１６ａまでの長さとしては、接合具１の胴部２の全長よりも雄螺子部４にナット９が螺着される長さ分短く形成（接合具挿入部１５，１６に接合具１を挿入した際に少なくともナット９が螺着できる長さ分雄螺子部４が縦構造部材１１の外周壁部から突出する長さで形成）されている。
更に、実施の形態２では、固定部材挿入部１８としては、接合具１の貫通孔３と略同一径で形成されている。
また、固定部材挿入部１８は、接合具１を接合具挿入部１５，１６に挿入し貫通孔３に胴部固定部材１０を挿着して接合具挿入部１５，１６に接合具１を挿着した際に、接合具１の貫通孔３側の端部が接合具挿入部１５，１６の底部１５ａ，１６ａに当接しない位置に形成されている。これにより、接着剤の注入口６から注入され吐出口７から吐出された接着剤を接合具１の外周面と接合具挿入部１５，１６の周壁面との間にスムーズに充填することができるとともに、接着剤の充填ムラを防止できる。
【００５２】
以上のように構成された実施の形態２の構造部材の接合構造について、以下その接合方法を説明する。
まず、挿入部形成工程において、横架構造部材１２を起重機等で持ち上げて縦構造部材１１と横架構造部材１２を当接面１４ａで当接させ、縦構造部材１１の外周壁部から当接面１４ａに対して直角に横架構造部材１２の所定部まで接合具挿入部１５を穿孔し、次いで、構造部材１３を起重機等で持ち上げて縦構造部材１１と構造部材１３を当接面１４ｂで当接させ、縦構造部材１１の外周壁部から当接面１４ｂに対して直角に構造部材１３の所定部まで接合具挿入部１６を穿孔する。
次に、接合具挿入部１５，１６の底部１５ａ，１６ａ側に、横架構造部材１２，構造部材１３の側面の外周壁部から接合具挿入部１５，１６に直交し横架構造部材１２，構造部材１３を貫通した固定部材挿入部１８を穿孔する。
更に、接合具挿入部１５，１６の底部１５ａ，１６ａ側に、横架構造部材１２，構造部材１３の上面又は側面の外周壁部から接合具挿入部１５，１６に連通した空気抜き部１７を穿設する。尚、この挿入部形成工程は、建築物の建築現場で行うこともできるが、予め工場でプレカット方式等で形成しておくこともできる。
【００５３】
次に、胴部挿着工程において、接合具挿入部１５，１６に接合具１を挿入し、固定部材挿入部１８から接合具１の貫通孔３に胴部固定部材１０を挿着し、接合具１の胴部２を接合具挿入部１５，１６に挿着する。
次いで、固定工程において、縦構造部材１１の外周壁部に突出した接合具１の雄螺子部４に座金８を外嵌するとともにナット９を雄螺子部４に螺着し、接合具１を接合具挿入部１５，１６に固定し、縦構造部材１１と横架構造部材１２，縦構造部材１１と構造部材１３を各々連結する。
ここで、ナット９は雄螺子部４に緩く螺着し、縦構造部材１１と横架構造部材１２，構造部材１３にガタつきを残しておくのが好ましい。これにより、他の構造部材の接合作業性を向上できる。
次に、他の構造部材の接合等が終了した後、ナット９を締めつけて雄螺子部４に確実に螺着して縦構造部材１１と横架構造部材１２，縦構造部材１１と構造部材１３の各当接面１４ａ，１４ｂを各々密着させる。これにより、接合具１の注入口６から中空部５に注入し吐出口７から接合具挿入部１５，１６内に吐出された接着剤が、当接面１４ａ，１４ｂから漏れるのを防止する。
【００５４】
次いで、固結工程において、注入口６から中空部５へ接着剤を注入する。注入口６から中空部５へ接着剤を注入すると、中空部５や接合具挿入部１５，１６内の空気が空気抜き部１７から排出されるとともに、中空部５に注入された接着剤が吐出口７から吐出され、接合具１の胴部２の外周面と接合具挿入部１５，１６の周壁間に接着剤が充填される。更に、接合具１の外周面と接合具挿入部１５，１６の周壁間に接着剤が充填されると、空気抜き部１７から接着剤が溢れ出るため、空気抜き部１７から溢れ出る接着剤を確認して接着剤の注入を終了し、縦構造部材１１と横架構造部材１２，構造部材１３が固結される。
ここで、接着剤としては、エポキシ樹脂系接着剤，ポリウレタン系接着剤，酢酸ビニル樹脂系接着剤等が用いられる。
尚、接合具１の使用本数は、接合する構造部材の大きさ等により、任意に変更される。また、接合具１の使用本数が多い場合、荷重を分布させることができるとともに、接合具１を小型化することができ構造部材の断面欠損を減少することができ接合強度を向上できる。
【００５５】
以上のように実施の形態１における接合具及びそれを用いた実施の形態２における構造部材の接合構造並びに接合方法によれば、以下の作用を有する。
（１）接合具が、貫通孔，雄螺子部，中空部，注入口，吐出口を有した棒状の胴部と、座金，ナット，胴部固定部材からなり、接合具の構造や形状が単純で加工性に優れ、接合具の生産性に優れる。
（２）縦構造部材と横架構造部材，縦構造部材と構造部材を連通して穿孔された接合具挿入部に接合具を挿入し、横架構造部材，構造部材に接合具挿入部に直交して穿孔された固定部材挿入部から接合具の貫通孔に胴部固定部材を挿着し、接合具の雄螺子部にナットを螺着するだけで各構造部材同士を連結，接合でき、更に、接合具の中空部に注入口から接着剤を注入することにより、接着剤が吐出口から吐出され接合具の外周面と接合具挿入部の周壁間に接着剤を充填でき、各構造部材を確実に固結でき、簡単にラーメン接合構造が得られる。
（３）胴部固定部材により接合具を接合具挿入部に挿着した後、接合具の雄螺子部にナットを螺着しているので、ナットを締めつけることにより、各構造部材の当接面を密着させることができ、接合具の中空部から接合具の外周面と接合具挿入部の周壁間に接着剤を充填した際に、接着剤が当接面から漏れるのを防止できる。
（４）各構造部材に接合具挿入部及び固定部材挿入部を形成し、接合具挿入部に接合具を挿入して固定部材挿入部から接合具の貫通孔に胴部固定部材を挿着するだけで接合具を接合具挿入部に挿着できるとともに、接合具の雄螺子部にナットを螺着するだけで、各構造部材同士を連結，接合でき、構造部材の接合作業性に優れる。
（５）接合具の雄螺子部にナットを緩く螺着して、接合する構造部材間にガタつきを残すことにより、他の各構造部材の組み立て作業性を向上できる。
（６）横架構造部材及び構造部材に接合具挿入部に連通した空気抜き部を有しているため、接合具の中空部に接着剤を注入する際に、中空部内や接合具挿入部内の空気が空気抜き部から排出され、接着剤がスムーズに充填できるとともに、接着剤注入時に空気抜き部から接着剤が溢れ出るのを確認することで、接合具の外周面と接合具挿入部の周壁間に接着剤が満たされたことを確認できる。
（７）接合具を各構造部材に形成された接合具挿入部に挿着して各構造部材を接合するとともに、接合具の外周面と接合具挿入部の周壁間に接着剤を充填して構造部材同士を固結しているため、構造部材を剛接合することができ、構造部材の曲げ、引張り、圧縮、剪断等に対する抵抗力を向上させることができる。
（８）接合具が各構造部材に埋設されているとともに、接合具の外周面が接着剤で被覆されるため、接合具が酸化等するのを防止でき接合具の耐久性を向上することができ、また、構造部材の伸縮を吸収でき、構造部材間のガタつきを防止できる。
（９）複数の接合具を用いて構造部材同士を接合する場合、接合具の胴部の外径を小さくすることができ、構造部材の断面欠損を減少でき構造部材の強度の低下を防止することができる。
（１０）接合具挿入部に、金属製の接合具が接着剤で埋設固定されるので、高剪断，高張力の剛接合を維持することができ、構造部材の接合強度に優れる。
【００５６】
（実施の形態３，４）
本発明の実施の形態３における接合具について、以下図面を用いて説明する。図４は実施の形態４における分割式の接合具の要部分解全体斜視図である。尚、実施の形態１と同様のものには同一の符号を付して説明を省略する。
図４において、２０は実施の形態４におけるステンレス等の金属製で複数に分割自在な分割式の接合具、２１は一端に雄螺子部４を有した頭部部材、２１ａは頭部部材２１の他端に形成された雌螺子状の接合部、２２は接合具２０の胴部材、２２ａは胴部材２２の一端に雄螺子状に形成され接合部２１ａに脱着自在な胴接合部、２２ｂは胴部材２２の他端に雌螺子状に形成された胴接合部、２３は一端に貫通孔３を有した先端部材、２３ａは先端部材２３の他端に雄螺子状に形成され胴接合部２２ｂに脱着自在な接合部、２４は頭部部材２１，胴部材２２，先端部材２３からなる接合具２０の胴部、５ａ，５ｂ，５ｃは頭部部材２１，胴部材２２，先端部材２３の略軸心の長手方向に各々形成された単位中空部、５′は頭部部材２１，胴部材２２，先端部材２３を接合した際に単位中空部５ａ，５ｂ，５ｃで形成される長さ方向が略一直線の中空部、７′は中空部５′の単位中空部５ｃの端部と直交して先端部材２３に穿設され中空部５′と連通して対称位置に形成された接着剤の吐出口、２５は一端部に頭部２５ａを有し貫通孔３に挿着される釘状の胴部固定部材である。
ここで、接合具２０の胴部２４は、頭部部材２１の接合部２１ａに胴部材２２の胴接合部２２ａを螺着し、また、胴部材２２の胴接合部２２ｂに先端部材２３の接合部２３ａを螺着して形成される。
尚、実施の形態２では、貫通孔３は胴部２４の外径の０．３倍〜０．８倍の大きさで形成されている。また、中空部５′や注入口６，吐出口７′は、胴部２４の外径の１／１０倍〜５／１０倍の大きさの直径で断面略円形状に形成されている。
【００５７】
以上のように構成された実施の形態３の接合具２０を用いて、以下、実施の形態４における木造建築物の構造部材の接合構造について、図面を用いて説明する。
図５（ａ）は実施の形態４における構造部材である登り梁の接合構造を示す要部側面断面図であり、図５（ｂ）は図５（ａ）のＢ−Ｂ線断面端面図である。尚、実施の形態２と同様のものには同一の符号を付して説明を省略する。
図５において、２６ａ，２６ｂは登り梁の構造部材、２７は構造部材２６ａ，２６ｂの当接面、２８は構造部材２６ｂの外周壁部から当接面２７に対して傾斜角度αを有して構造部材２６ａの軸心と略平行に構造部材２６ａの所定部まで穿孔された接合具挿入部、２８ａは接合具挿入部２８の底部、２９は接合具挿入部２８の開口部側の接合具挿入部２８に連通して構造部材２６ｂの上外周壁部に穿孔された空気抜き部、３０は接合具挿入部２８の開口部に接合具挿入部２８の外径より大きな径で形成され接合具挿入部２８と直交した座部、３１は座部３０に埋設され表面が構造部材２６ｂの外周壁面と略面一に形成された埋設材（封止体）、３１ａは接合具２０の注入口６に嵌合され注入口６を封止する突起部、３２は接合具２０の胴部２４に外嵌され接合具挿入部２８内に配設されるスプリング等の螺旋状部材、３３は構造部材２６ａの側面の外周壁部から接合具挿入部２８に直交して接合具挿入部２８の底部２８ａ側に所定深さ穿孔された固定部材挿入部である。
【００５８】
ここで、実施の形態４では、接合具挿入部２８は、接合具２０の胴部２４と接合具２０の胴部２４に外嵌された螺旋状部材３２が挿入できるとともに胴部２４と接合具挿入部２８の周壁間で螺旋状部材３２に沿って接着剤を流動させることができる大きさ（例えば、螺旋状部材３２の外径より０ｍｍ〜１５ｍｍ大きな直径）で形成されている。螺旋状部材３２の螺旋間隔等にもよるが、接合具挿入部２８の直径と螺旋状部材３２の直径との差が０ｍｍよりも小さくなると接合具挿入部２８に胴部２４に外嵌した螺旋状部材３２を挿入できなくなり、差が１５ｍｍよりも大きくなるにつれ必要以上に接着剤を要す傾向が有る。
更に、座部３０から接合具挿入部２８の底部２８ａまでの長さとしては、接合具２０の胴部２４の全長よりも雄螺子部４にナット９が螺着される長さ分短く形成（接合具挿入部２８に接合具２０を挿入した際に少なくともナット９が螺着できる長さ分雄螺子部４が座部３０から突出する長さで形成）されている。
【００５９】
座部３０は、接合具挿入部２８の開口部に座金８を当接できる段差部ができるように、接合具挿入部２８の外径より大きな径で形成される。また、座部３０はナット９を埋設材３１で埋設できる大きさで形成される。
また、実施の形態４では、固定部材挿入部３３としては、接合具２０の貫通孔３と同じ大きさで、構造部材２６ａに所定深さで形成されている。これにより、釘状の胴部固定部材２５を固定部材挿入部３３及び接合具２０の貫通孔３に挿入して胴部固定部材２５の頭部２５ａを打設することにより、胴部固定部材２５の先端を構造部材２６ａに打ち込んで胴部固定部材２５を固定部材挿入部３３に固定することができる。
更に、固定部材挿入部３３は、接合具２０を接合具挿入部２８に挿入し貫通孔３に胴部固定部材２５を挿着して接合具挿入部２８に接合具２０を挿着した際に、接合具２０の貫通孔３側の端部が接合具挿入部２８の底部２８ａに当接しない位置に形成されている。これにより、接合具２０の外周面と接合具挿入部２８の周壁面間との間にスムーズに接着剤を充填することができるとともに、接着剤の充填ムラを防止できる。
【００６０】
以上のように構成された実施の形態４の構造部材の接合構造について、以下その接合方法を説明する。
まず、挿入部形成工程において、構造部材２６ａ，２６ｂを起重機等で持ち上げて構造部材２６ａ，２５ｂを当接面２７で当接させ、構造部材２６ｂの外周壁部から当接面２７に対して傾斜角度αで構造部材２６ａの所定部まで接合具挿入部２８を穿孔するとともに、接合具挿入部２８の開口部側に座部３０を形成する。
次に、接合具挿入部２８の底部２８ａ側に、構造部材２６ａの側面の外周壁部から接合具挿入部２８に直交した固定部材挿入部３３を所定深さ穿孔する。
更に、接合具挿入部２８の開口部側に、構造部材２６ｂの上面の外周壁部から接合具挿入部２８に連通した空気抜き部２９を穿設する。
尚、この挿入部形成工程は、建築物の建築現場で行うこともできるが、予め工場でプレカット方式等で形成しておくこともできる。

次に、胴部挿着工程において、頭部部材２１，胴部材２２，先端部材２３を各接合部２１ａ，２２ａ，２２ｂ，２３ａで螺着して形成された胴部２４に螺旋状部材３２を外嵌し、胴部２４と螺旋状部材３２を接合具挿入部２８に挿入する。次いで、固定部材挿入部３３から接合具２０の貫通孔３に胴部固定部材２５を挿入し、胴部固定部材２５の頭部２５ａを打設して胴部固定部材２５の先端を構造部材２６ａに打ち込み、接合具２０の胴部２４及び螺旋状部材３２を接合具挿入部２８に挿着する。
次に、固定工程において、座部３０に突出した接合具２０の雄螺子部４に座金８を外嵌するとともにナット９を雄螺子部４に螺着し、接合具２０を接合具挿入部２８に固定し、構造部材２６ａ，２６ｂを各々連結する。
ここで、ナット９は雄螺子部４に緩く螺着し、構造部材２６ａと構造部材２６ｂ間にガタつきを残しておくのが好ましい。これにより、他の構造部材の接合作業性を向上できる。
次に、他の構造部材の接合等が終了した後、ナット９を締めつけて雄螺子部４に確実に螺着して構造部材２６ａ，２６ｂの当接面２７を各々密着させる。これにより、接合具２０の注入口６から中空部５′に注入し吐出口７′から接合具挿入部２８内に吐出された接着剤が、当接面２７から漏れるのを防止する。
【００６２】
次いで、固結工程において、注入口６から中空部５′へ接着剤を注入する。注入口６から中空部５′へ接着剤を注入すると、中空部５′や接合具挿入部２８内の空気が空気抜き部２９から排出されるとともに、中空部５′に注入された接着剤が吐出口７′から吐出され、接合具２０の胴部２４の外周面と接合具挿入部２８の周壁間に接着剤が充填される。更に、接合具２０の外周面と接合具挿入部２８の周壁間に接着剤が充填されると、空気抜き部２９から接着剤が溢れ出るため、空気抜き部２９から溢れ出る接着剤を確認して接着剤の注入を終了し、次に、埋設材３１の突起部３１ａを注入口６に嵌合して座部３０に埋設材３１を埋設し、構造部材２６ａと構造部材２６ｂを固結する。
ここで、接着剤としては、エポキシ樹脂系接着剤，ポリウレタン系接着剤，酢酸ビニル樹脂系接着剤等が用いられる。
尚、接合具２０の使用本数は、接合する構造部材の大きさ等により、任意に変更される。また、接合具２０の使用本数が多い場合、荷重を分布させることができるとともに、接合具２０を小型化することができ構造部材の断面欠損を減少することができ接合強度を向上できる。
【００６３】
以上のように実施の形態３における接合具及びそれを用いた実施の形態４における構造部材の接合構造並びに接合方法によれば、実施の形態１，２の作用に加えて、以下の作用を有する。
（１）接合具が、一端に頭部を有し他端に接合部を有した頭部部材と、両端に胴接合部を有した胴部材と、一端に接合部を有し他端に貫通孔を有した先端部材と、を有しているため、各接合部で各部材を接合することにより、該接合具を形成することができ、接合する胴部材の数により該接合具を任意の長さに調整できる。
（２）接合具が、頭部部材，胴部材，先端部材に分割されているため、中空部を形成する際に、各部材毎に長さの短い単位中空部を形成することにより接合具の中空部を形成することができ、特に、先端部側に吐出口を形成する場合に、中空部を容易に形成することができる。
（３）接合具の胴部にスプリング等の螺旋状部材を外嵌し、接合具と螺旋条部材を接合具挿入部に挿入しているため、接合具の中空部に接着剤を注入した際に、接合具の吐出口から接合具の外周面及び接合具挿入部の周壁間で螺旋状部材に沿って接着剤を略均等に充填することができ、接着剤の充填ムラを防ぎ構造部材同士を固結できる。
（４）接合具の胴部に螺旋状部材を外嵌しているため、接着剤で螺旋状部材が接合具挿入部内に埋設され該接合具が補強材としての役割を果たし、構造部材同士の接合部分の剪断，引張り応力等を向上させることができる。
（５）接合具を接合具挿入部に挿入し、接合具の外周面と接合具挿入部の周壁間に接着剤を充填して構造部材同士を固結しているため、接合具が頭部部材，胴部材，先端部材を接合して形成されている場合、各部材の接合部が接着剤で被覆され、接合具の強度を向上できる。
（６）接着剤の吐出口が接合具の先端部材に形成され、空気抜き部が吐出口と反対側（遠方側）に形成されているため、接着剤を接合具挿入部全体に注入することができ接着剤の充填ムラを防ぎ確実に構造部材同士を固結できる。
（７）胴部固定部材として釘状のものを用いた場合、胴部固定部材を固定部材挿入部から接合具の貫通孔に挿入し胴部固定部材を打設するだけで、胴部固定部材を構造部材に固定できるとともに接合具を接合具挿入部に固定することができ、胴部挿着工程の作業性に優れる。
（８）釘状の胴部固定部材により接合具を接合具挿入部に確実に挿着固定することができるとともに、ナットを雄螺子部に螺着することにより構造部材同士を引き寄せて当接面を強固に密接させることができ、接着剤が当接面から漏れるのを防止でき、また、接着剤により各構造部材と接合具を強固に接着固定することができ機械的強度に優れたラーメン接合が得られる。
（９）接合具挿入部の開口部に接合具挿入部と直交した座部を形成しているので、当接面に対して傾斜角度を有した接合具挿入部に接合具を挿着する際にも、接合具の座金やナットを座部に当接させてナットを雄螺子部に確実に螺着することができるとともに構造部材同士をナットの螺着により引き寄せて接合することができる。
（１０）接合具挿入部の開口部に座部を穿設しているので、接合具のナットが構造部材の表面から大きく突出するのを防止でき、また、座部に埋設される埋設材（封止体）を有し、更に、座部に埋設材を埋設した際に埋設材が構造部材の外周壁面と略面一になるように形成されているので、構造部材の外観を向上できる。
（１１）座部の開口側に埋設材を埋設しているため、接合具のナットや胴部の雄螺子部側端部が露出するのを防止でき、火災時等に構造部材の炭化皮膜により接合具を火災の高温から守ることができるとともに、接合具を介して外部の熱を構造部材の内部に伝えるの防止でき、構造部材の接合部分の安全性を向上できる。
（１２）埋設材が、接合具の注入口に嵌合される突起部を有しているため、突起部を注入口に嵌合して注入口を封止することができ、特に、粘度の極めて低い接着剤や硬化に長時間を要す接着剤を使用した場合でも、注入口から接着剤が漏れるのを防止でき、接着効果が低下するのを防止できる。

（実施の形態５）
本発明の実施の形態３の接合具２０を用いて、以下、実施の形態５における木造建築物の構造部材の接合構造について、図面を用いて説明する。
図６は実施の形態５における構造部材の継手接合構造を示す要部側面断面図であり、図７は実施の形態５における構造部材の継手接合構造を示す要部分解平面図である。尚、実施の形態２乃至４と同様のものには同一の符号を付して説明を省略する。
図中、１２Ａ，１２Ｂは縦構造部材１１を介して接合される桁等の横架構造部材、４０ａは縦構造部材１１と横架構造部材１２Ａの当接面、４０ｂは縦構造部材１１と横架構造部材１２Ｂの当接面、４１ａ，４１ｂは横架構造部材１２Ａ，１２Ｂの外周壁部から当接面４０ａ，４０ｂに対して傾斜角度αを有して縦構造部材１１を貫通して横架構造部材１２Ｂ，１２Ａの所定部まで穿孔された接合具挿入部、４１ｃは接合具挿入部４１ａ，４１ｂの底部、４２ａ，４２ｂは接合具挿入部４１ａ，４１ｂの開口部側の接合具挿入部４１ａ，４１ｂに連通して横架構造部材１２Ａ，１２Ｂの上外周壁部に穿孔された空気抜き部、４３ａ，４３ｂは横架構造部材１２Ａ，１２Ｂの側面の外周壁部から接合具挿入部４１ａ，４１ｂに直交して接合具挿入部４１ａ，４１ｂの底部４１ｃ側に所定深さ穿孔された固定部材挿入部である。
【００６５】
ここで、実施の形態５では、接合具挿入部４１ａ，４１ｂの傾斜角度αは、当接面４０ａ，４０ｂに対して２０°≦α≦７０°若しくは３０°≦α≦６０°で形成されている。傾斜角度αが３０°よりも小さくなるにつれ接合具挿入部４１ａ，４１ｂの形成位置が当接面４０ａ，４０ｂ側に近づき横架構造部材１２Ａ，１２Ｂの端部側になり、外力に対して横架構造部材１２Ａ，１２Ｂが破損し易くなる傾向が有り、傾斜角度αが６０°よりも大きくなるにつれ接合具２０の長さが長くなりすぎて接合作業性が低下する傾向が有る。
【００６６】
以上のように構成された実施の形態５の構造部材の接合方法は、実施の形態２，４と同様なので、説明を省略する。
尚、実施の形態５では、挿入部形成工程で接合具挿入部４１ａ，４１ｂ、座部３０、空気抜き部４２ａ，４２ｂ、固定部材挿入部４３ａ，４３ｂを形成した後、胴部挿着工程，固定工程において、接合具２０の胴部２４を接合具挿入部４１ａ，４１ｂの両方に挿着して、縦構造部材１１，横架構造部材１２Ａ，１２Ｂを連結した後、固結工程を行う。ここで、接合具挿入部４１ａ，４１ｂに接合具２０の胴部２４を挿入するだけで縦構造部材１１，横架構造部材１２Ａ，１２Ｂを連結することができるので、胴部挿着工程で接合具２０の胴部２４を接合具挿入部４１ａ，４１ｂの両方に挿入した後、固定工程，固結工程を行ってもよい。
【００６７】
以上のように実施の形態３における接合具を用いた実施の形態５における構造部材の接合構造並びに接合方法によれば、実施の形態１乃至４の作用に加えて、以下の作用を有する。
（１）接合具を横架構造部材の上方から接合具挿入部に挿入し、胴部固定部材で接合具を接合具挿入部に挿着するだけで、容易に縦構造部材と横架構造部材を連結することができ、また、接合具の雄螺子部にナットを締めつけるだけで縦構造部材と横架構造部材の当接面を当接して接合することができ、縦構造部材を介して横架構造部材同士を接合する場合等、３，４方向に構造部材が有る場合にも、該接合具を用いて容易に構造部材同士を接合することができる。
（２）縦構造部材と横架構造部材の当接面に対して傾斜角度αを有して接合具挿入部を形成し、接合具挿入部に接合具を挿着しているので、横架構造部材の鉛直荷重に対する変形に耐えることができ、構造部材同士の接合力を向上できる。
（３）接合具挿入部がクロス状に形成され、各接合具挿入部に挿着された各接合具がクロス状になっているので、地震，風等の水平力により生じる構造部材の接合部分の引張り，圧縮，曲げ，剪断によって発生する上下左右からの荷重を各々の接合具の偶力で打ち消すことができ、構造部材の接合部分の剛性を向上できる。
（４）座部の開口側に埋設材を埋設しているため、接合具を各構造部材に完全に埋設することができ、接合具が各構造部材から露出せず、特に、火災時等に構造部材の炭化皮膜により接合具を火災の高温から守ることができるとともに、接合具を介して外部の熱を構造部材の内部に伝えるの防止でき、構造部材の接合部分の安全性を向上できるとともに、各構造部材の外観を向上できる。

【００７０】
以上のように構成された実施の形態７の構造部材の接合方法は、実施の形態２，４と同様なので、説明を省略する。
尚、実施の形態７では、胴部固定部材５３が頭部５３ａに＋状の係合溝を有したラグスクリューからなるため、胴部挿着工程において、接合具５０の胴部５１を胴部固定部材５３で接合具挿入部５８に挿着する際、固定部材挿入部６０から接合具５０の貫通孔３に胴部固定部材５３を挿入し、胴部固定部材５３の頭部５３ａの係合溝にドライバー等の工具を係合して胴部固定部材５３を横架構造部材５６に螺着することにより、接合具挿入部５８に胴部５１を挿着固定する。
ここで、実施の形態７では、固定部材挿入部６０の開口側に凹部６０ａを有しているので、胴部固定部材５３の頭部５３ａは凹部６０ａに嵌合される。

（１）接合具の胴部が、外周面にリブや節を有した異型鉄筋からなるため、接合具挿入部に挿着固定された接合具の胴部の外周面と接合具挿入部の周壁間に接着剤を充填した際の、胴部と接合具挿入部との接着効果を向上することができ、接合具と接合具挿入部との接着力に優れ、縦構造部材と横架構造部材の接合部分の接合力を向上できる。
（２）固定部材挿入部の開口側に凹部を有しているので、胴部固定部材の頭部を凹部に嵌合することができ、胴部固定部材の頭部が構造部材の外周壁面の突出するのを防止でき、構造部材の外観を向上できる。

[0002]
[Prior art]
Traditionally, in Japan, many Japanese-style houses and sukiya-style houses have been built with large openings on the south surface, open spaces such as wide rooms and continuous Japanese-style rooms, large floors, etc. .
On the other hand, recently, the construction of wooden three-story houses in urban areas with a small site has been increasing, and it is required to set up a garage on the first floor due to the small land and site, requiring a large frontage on the first floor. Many things are built.
Hereinafter, an example of a three-story house having a garage on the first floor will be described with reference to the drawings.
11A is a first floor plan of a three-story house, FIG. 11B is a second floor plan of the three-story house, and FIG. 11C is a third floor plan of the three-story house. FIG.
In the figure, 100a and 100b are pillars, 101 is a bearing wall disposed between the pillars 100b, 102 is a garage, and 102a is an opening of the garage 102.
In the three-story house of FIG. 11, since the entrance 102a of the garage 102 is required, the bearing wall 101 cannot be arranged between the pillars 100a as between the pillars 100b, and the second floor and the third floor above the garage 102. Since a floor load is applied, conventionally, a large structural member has been used for the pillar 100a, or only the first floor has a steel structure or an RC structure.
[0003]
Also, in recent years, in these buildings such as houses, for the purpose of labor saving, rationalization, or improvement of the strength of wooden buildings, joints, metal fittings, joints using box hardware, etc. Joining structures and joining methods for structural members that join the girders, columns, beams and columns, and trunks and through columns have been developed.
In addition, every year, including the Great Hanshin Earthquake, wooden houses often suffer great damage due to earthquakes, typhoons, etc. In the joint structure between structural members of wooden buildings, including improving the strength of joints such as joints. Various joining structures and joining methods for structural members that have improved the structural strength of the entire building have been developed.
[0004]
For example, Japanese Utility Model Laid-Open No. 63-86411 (hereinafter referred to as “a”) discloses a curable resin adhesive comprising a central hole opened at one end of a bolt and a lateral hole communicating the central hole with a side surface of the bolt. A wood assembly bolt having an injection channel is disclosed.
[0005]
Japanese Utility Model Laid-Open No. 5-38412 (hereinafter referred to as “B”) discloses a bolt for fastening a laminated material and introducing an adhesive into a gap between bolt holes for fastening. An adhesive injection bolt is disclosed in which a recess for circulating an adhesive is formed on the outer periphery of the shaft portion, and at least two through passages communicating with the recess and opening outward are formed on the head.
[0006]
In Japanese Patent Laid-Open No. 6-10419 (hereinafter referred to as “C”), a common joint is inserted into at least two connected materials so that the connected materials are abutted and provided on the connected material. In the framework connection mechanism in which the bolt is passed through the bolt hole formed in the joint and the bolt hole provided in the joint, and the bolt is fastened and fixed with a nut, the bolt has one opening that opens to the outside when the bolt is tightened And a connecting mechanism for a framework in which a communicating path is provided, and a filler is filled in at least a gap between the bolt hole of the joint and the bolt through the communicating path. Yes.
[0007]
[Problems to be solved by the invention]
However, the conventional joining tool and the joining structure and joining method of structural members have the following problems.
When using metal fittings, hardware, etc. for joining structural members of wooden buildings, it is necessary to attach the metal fittings, hardware, etc. to the structural members and fix them to each other via bolts, nuts, etc. In addition to lack of workability, the work during construction is complicated and lacks workability. Also, due to the expansion and contraction of the wood, the fixing force is likely to be lowered and looseness is likely to occur in several years, resulting in lack of reliability in the joint strength. The joint part of the structural member requires physical strength such as bending, pulling, compression, shearing, etc., so that the metal fittings and hardware used for joining the structural member become large, heavy and lacking in transportability. Lack of safety when working at heights.
When structural members made of wood are fixed together with bolts and nuts, the tightening force decreases due to expansion and contraction of the wood in several years, and looseness is likely to occur, and physical strength is increased by oxidation of metal parts such as bolts, nuts, and hardware. It had a problem that it was lowered and lacked in reliability and durability.
[0008]
In the conventional joint structure, the joint part of the structural member is a pin joint, so the strength of the wooden building is insufficient, bracing, structural plywood, steel braces, etc. are required, and in the event of an earthquake, etc. Sometimes the braces break or come off and do not play their original role and are unreliable.
In addition, in the case of Japanese-style houses and sukiya-style houses with an open floor plan, braces and load-bearing walls can be provided in open areas such as large openings, wide margins, and continuations of Japanese-style rooms. The center of gravity of the building and the center of the bearing wall are separated from each other, and the building itself tends to shake greatly in the event of an earthquake, etc., and the building tends to collapse. The problem was lacking in safety and safety.
[0009]
In addition, since a garage 102 is provided on the first floor in a three-story house as shown in FIG. 11, a bearing wall cannot be arranged between the pillars 100a, and the second and third floors are located above the garage 102. In the event of an earthquake, there is a high possibility of being destroyed from the pillar 100a of the garage 102, and the earthquake resistance and safety are lacking. Furthermore, since the bearing wall 101 cannot be formed at the front door 102a of the garage 102, the entire house is likely to be shaken by an earthquake or vibration of the second to third floors. In this case, in particular, the cross on the third floor wall may be distorted or broken. There is sex. Furthermore, when a large-sized structural member is used for the pillar 100a or only the first floor is made of a reinforcing bar structure, there is a problem that it takes time for construction, lacks construction workability, and increases costs.
[0010]
In addition, the following problems have been encountered in Nos. 1 to C.
In each of the A to C publications, after connecting the members (materials to be connected) with bolts and nuts, the bolts are connected through holes or recesses into which the adhesive formed on the bolts is injected (circulated). Since the adhesive is filled between the outer peripheral surface and the bolt hole through which the bolt is inserted, the members are joined to each other. Therefore, if the bolt hole through which the bolt is inserted is not penetrated by the members to be connected, the members are connected. Therefore, for example, the bolts and nuts of No. 1 to No. C cannot be used for joining a beam and a column, which lacks versatility and usability.
In addition, when joining beams and columns, after connecting common joints to the materials to be joined and bringing the materials to be joined together, as shown in C, the materials to be joined must be joined with bolts and nuts. In addition to the bolts and nuts, a “joint” member is required, and the number of parts increases, resulting in poor handling and member joining workability.
[0011]
The present invention solves the above-described conventional problems, and has a simple structure and excellent workability in jointing, and can significantly shorten the construction period, provide a joint with high structural strength, and improve the structural strength of a wooden building. In addition, it can be expanded and seismically strengthened existing buildings, and is excellent in earthquake resistance and safety. Also, it is excellent in safety during construction work, and it has excellent versatility. Provided a joining method of structural members that can significantly improve the joining structure of structural members that can be joined and construction workability, simplify the joining technology of structural members, reduce the work man-hours, and shorten the construction period. The purpose is to do.
[0012]
[Means for Solving the Problems]
In order to solve the above-described conventional problems, a joining tool according to the present invention, a joining structure of a structural member using the same, and a joining method of the structural member have the following configurations.
The connector according to claim 1 of the present invention comprises: a. A solid rod-shaped body; b. A through-hole penetrating substantially perpendicular to the axis of the barrel portion on one end side of the barrel portion; c. A male screw portion formed on the other end side of the body portion; d. A hollow portion formed in the longitudinal direction of the substantially axial center of the barrel portion; e. An adhesive injection port communicating with the hollow portion from an end surface of the body portion on the male screw side; f. One or more adhesive outlets drilled from the outer peripheral surface of the body portion to the hollow portion; and g. A nut screwed onto the male screw portion; h. And a trunk portion fixing member inserted into the through hole.
[0013]
This has the following effects.
(1) The connector comprises a rod-shaped body having a through hole, a male screw, a hollow, an injection port, and a discharge port, a nut, and a body fixing member. The structure and shape of the connector However, it is simple and excellent in workability, and the productivity of the connector can be improved.
(2) When joining wood, laminated wood, or wood and laminated wood, or wood and stone, concrete, or other members, an insertion portion is formed in the member to be joined, and the joining tool is inserted into the insertion portion. Then, by simply inserting the body fixing member from the outer peripheral wall side of the member into the through-hole of the connector and screwing the nut onto the male screw portion of the body, the members can be easily joined together. be able to.
(3) Since it has a hollow portion in the longitudinal direction of the body portion of the connector and an adhesive discharge port that is drilled in communication with the hollow portion, an adhesive is provided from the injection port to the hollow portion. By injecting, the adhesive can be filled from the discharge port to the outer peripheral surface of the body portion of the joint and the peripheral wall of the insertion portion of the member into which the joint is inserted, and the members are securely consolidated and rigidly joined. can do.
(4) When joining members using a plurality of joints, the outer diameter of the body part of the joints can be reduced, the cross-sectional defects of the members can be reduced, and the strength of the members can be prevented from being lowered. .
(5) Since a joint made of a high-strength member made of metal or the like is embedded and fixed with an adhesive in an insertion portion for inserting the joint formed on the member, it is possible to maintain high shear and high tension rigid joint Moreover, since the trunk | drum of a joining tool is fixed in an insertion part with the trunk | drum fixing member inserted by the through-hole, the joint strength of members can be improved with the shear force and toughness of a trunk | drum fixing member.
(6) The connector is inserted into the insertion portion formed in the member, the body fixing member is inserted into the through hole of the connector from the outer peripheral wall side of the member, and the nut is screwed into the male screw portion of the body. By doing this, the members can be brought close together so that the contact surfaces of the members can be brought into close contact with each other, leakage of the adhesive from the contact surfaces between the members can be prevented, and the members can be reliably brought into close contact with each other.
(7) In particular, when joining the pillar and the lintel, the joining tool is inserted into the insertion portion formed in communication with the lintel from the outer peripheral wall portion of the pillar, and the joining tool penetrates from the outer peripheral wall portion of the lintel. After inserting the body fixing member into the hole and screwing the nut into the male screw part of the body part, simply injecting the adhesive from the injection port into the hollow part, the column and the lintel can be joined firmly It is possible to improve the yield strength of the opening between the columns, and to prevent the shaft assembly from being deformed by a horizontal force.

The joint material is made of stainless steel, chromium, steel, carbon steel and other metal products such as aluminum alloy, carbon fiber, boron fiber, glass fiber, metal fiber and other organic and inorganic fibers. The one molded with resin is used.
[0015]
The through hole of the connector is preferably formed with a size of 0.3 to 0.8 times the outer diameter of the body portion. As the through hole becomes smaller than 0.3 times the outer diameter of the body part, the outer diameter of the body part fixing member inserted into the through hole also becomes smaller, and the shearing force of the body part fixing member is reduced, so that The rigidity of the body when it is inserted into the member tends to decrease, and as the through hole becomes larger than 0.8 times the outer diameter of the body part, the through hole formed in the body part becomes larger. There is a tendency that the shearing force of the body decreases and the strength of the body portion decreases.
[0016]
The hollow portion of the connector and the discharge port or injection port of the adhesive connected to the hollow portion are about 1/20 times to 16/20 times, preferably about 1/10 times the outer diameter of the body portion of the connector. A cross section having a diameter 5/10 times larger is formed in a substantially circular shape. Note that, depending on the viscosity of the adhesive and the material of the connector, as the diameter becomes smaller than 1/10 times the outer diameter of the body of the connector, the fluidity of the adhesive in the hollow portion is lacking and the adhesive is injected. Tend to take time, and the mechanical strength of the joint tends to be lost as it becomes larger than 5/10 times.
[0017]
The discharge port communicates with the hollow portion and is formed in the diameter direction of the body portion of the connector. When two or more discharge ports are formed, they may be formed so as to communicate with the hollow portion and penetrate in the diameter direction of the body portion of the connector, or may be formed substantially radially around the hollow portion. Good. When two or more discharge ports are formed, the adhesive injected into the hollow portion is discharged from the plurality of discharge ports, so that the time for injecting the adhesive can be shortened. Furthermore, when the discharge port is formed at a symmetrical position from the hollow portion, the adhesive injected into the hollow portion can be discharged almost uniformly onto the outer peripheral surface of the joint tool, and uneven filling of the adhesive can be prevented.
As the discharge port formation position, when the connector is inserted while being inclined downward from the upper surface of the member, the discharge port is formed on the through hole side of the body portion of the connector, and the connector is inclined upward from the lower surface of the member. In the case of insertion, the discharge port is preferably formed on the male screw part side of the body part of the connector. Thereby, an adhesive agent can be uniformly filled between the outer peripheral surface of a connector, and the surrounding wall of the insertion part of the member in which the connector was inserted.
The body fixing member is formed in a size that can be inserted into the through hole according to the through hole, and a rod-like pin, a nail, a screw such as a lag screw, a coach screw, or the like is used. In addition, when a commercially available nail, a screw, or the like is used, the cost of the connector can be reduced.
[0018]
In addition, after joining the members with a conventional joint fitting such as a U-shaped box metal or a hook metal, an insertion portion is formed in each member and the joint is inserted, and the outer peripheral wall side of the member Alternatively, the body fixing member may be inserted into the through hole of the connector, the nut may be screwed into the male screw portion, and an adhesive may be injected into the hollow portion of the connector to bond the members together. In this case, the members can be joined to each other after the members are temporarily fixed with the joint metal fitting, so that the joining workability of the members can be improved and the joining accuracy can be improved. In addition to the joint fitting, it is possible to maintain the joint strength such as shear and tension between the members with the joint tool, and to reduce the size of the joint tool by using the joint bracket and the joint tool together. Furthermore, it is possible to prevent the building from being completely destroyed even if one of the joint fitting and the joint is damaged due to an earthquake or the like.

(G) Inserting the connector into the connector insertion portion of the structural member to bond the structural members together, and filling the adhesive between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion to connect the structural members Since structural members can be rigidly joined together, the joint strength can be improved, and since the adhesive is solidified with an adhesive, the expansion and contraction of structural members such as wood can be absorbed. Can be prevented.
(H) Since the joint portion between structural members is a rigid frame structure that is firmly joined to the joint by an adhesive, the building's frontage (span) can be remarkably widened without using bearing walls or bracing. A space without pillars can be obtained.
[0035]
Here, the length (total length) of the connector insertion portion is formed shorter than the total length of the body portion of the connector by a tightening amount of the nut (a length that allows the nut to be screwed onto the male screw portion) (connector insertion portion). The portion into which the nut of the male screw portion is screwed when the connector is inserted is formed with a length protruding from the opening side of the connector insertion portion. When the connector is inserted into the connector insertion portion, it is preferable that the end portion on the through hole side of the connector does not contact the bottom side of the connector insertion portion. As a result, the adhesive can be filled also between the end portion on the through-hole side of the connector and the bottom of the connector insertion portion, and between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion. The adhesive can be filled smoothly, uneven filling of the adhesive can be prevented, and the structural members can be securely consolidated.
[0036]
The connector insertion portion is formed at a position 1.1 to 6 times the outer diameter of the body portion of the connector inward from the outer peripheral wall surface of the structure member, depending on the size of the structure member. When a large external force is applied to the structural member as the joint insertion portion is positioned from the outer peripheral wall surface of the structural member to a position smaller than 1.1 times the outer diameter of the body of the joint, the end or surface of the structural member is damaged. As the position becomes larger than 6 times, the number of joint insertion portions that can be formed on the structural member decreases, and it is difficult to improve the bonding force between the structural members.
Moreover, as a magnitude | size of a connector insertion part, it forms 3 mm-15 mm larger than the outer diameter of the trunk | drum of a connector, Preferably it is 4 mm-12 mm larger. Depending on the material of the structural member and the type of adhesive, etc., as the difference between the outer diameter of the joint insertion part and the body of the joint becomes smaller than 4 mm, the type of adhesive and the construction period (summer, winter) ), But the adhesive discharged from the discharge port tends to hardly flow between the outer peripheral surface of the joint body and the peripheral wall of the joint insertion section. As the difference becomes larger than 12 mm, there is a tendency to require more adhesive than necessary, and when the difference between the body part of the joint and the outer diameter is smaller than 3 mm or larger than 15 mm, these tendencies become stronger. Become. In addition, when a helical member is externally fitted to the body of the connector and the connector and the spiral member are inserted into the connector insertion portion, depending on the outer diameter of the spiral member, the helical interval, etc., the connector A size that allows the spiral member to be inserted into the insertion portion and allows the adhesive to flow between the body portion of the connector and the peripheral wall of the connector insertion portion (for example, a diameter that is 0 mm to 15 mm larger than the outer diameter of the spiral member). Thus, the connector insertion portion is formed.
Furthermore, the connector insertion portion is formed in an arbitrary cross-sectional shape such as a circular shape, an elliptical shape, a polygonal shape such as a quadrangular shape or a hexagonal shape.
[0037]
The joint insertion portion is preferably formed with an inclination angle α when the structural member is subjected to a particularly large external force at the tip, such as a horizontal cantilever, or when a climbing beam is joined. The inclination angle α is 20 ° ≦ α <90 °, preferably 20 ° ≦ α ≦ 70 °, more preferably 30 ° ≦ α ≦ 60 ° with respect to the contact surface. Although it depends on the material of the structural member and the size of the connector, as the inclination angle becomes smaller than 30 °, the position of the connector insertion portion approaches the end of the structural member and the structural member is damaged by a large external force. There is a tendency to become easy, and as the inclination angle becomes larger than 60 °, the length of the connector tends to be too long and workability tends to be lowered, and when the inclination angle becomes smaller than 20 °, these tendencies are likely to occur. It becomes even stronger.
[0038]
In particular, when the connector insertion portion is formed from the upper outer peripheral wall portion side of the structural member, the connector can be easily inserted into the connector insertion portion from above the structural member, and the workability can be improved. It is possible to prevent the nut and the like of the connector from being exposed to the lower outer peripheral wall portion of the member, and to improve the appearance, and to reliably fill the adhesive between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion.
In addition, a structure is obtained in which other connector insertion portions are perforated so as to form a cross with the connector insertion portion at a predetermined interval on the contact surface of the structural member to be bonded, and the connector is inserted into each connector insertion portion. When the members are joined, loads from the top, bottom, left and right such as tension, bending, and shearing of the joined structural members can be canceled by the couple of each joint tool, and the joining force between the structural members can be improved.
Furthermore, by forming the connector insertion portion with an inclination angle α or forming a cross shape, the connector can be used even in the case of a two-way ramen structure or when there are structural members in three or four directions. Structural members can be joined together.
[0039]
The fixing member insertion portion is formed with substantially the same diameter as the through hole. Further, the fixing member insertion portion may be formed through the structural member, or may be formed at a predetermined depth in communication with the connector insertion portion, and further, there is a head at one end of the body fixing member. The one end of the fixing member insertion portion may be formed with a large diameter so that the head can be fitted. Furthermore, after inserting the trunk portion fixing member into the fixing member insertion portion, a plug such as a wooden plug may be driven into the opening of the fixing member insertion portion to be flush with the outer peripheral wall surface of the structural member. Thereby, the external appearance of a structural member can be improved.
In addition, it is preferable to form so that the axial center of a fixing member insertion part may be orthogonal to the axial center of a connector insertion part. As a result, when the barrel fixing member is inserted from the fixing member insertion portion into the through hole of the connector inserted in the connector insertion portion, the axis of the connector and the axis of the connector insertion portion are substantially aligned. The adhesive can be filled evenly between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion.
As the adhesive, an epoxy resin adhesive, a polyurethane adhesive, a vinyl acetate resin adhesive, or the like is used.

When the inlet side and the discharge port are formed on the inlet side of the body part of the connector, they are formed on the through hole side of the body part of the connector. As a result, the adhesive can be prevented from overflowing from the air vent before the adhesive is filled between the outer peripheral surface of the connector and the peripheral wall of the connector insertion portion. An adhesive can be filled between the peripheral walls. In addition, the air vent is formed in an arbitrary shape such as a substantially circular shape, a substantially elliptical shape, or a polygonal shape such as a quadrangle, and is pierced with a size that allows the adhesive to be smoothly injected.
Further, after the adhesive has overflowed from the air vent part, when the diameter of the air vent part is large, a plug such as a wooden plug may be driven to be flush with the outer peripheral wall surface of the structural member. Thereby, the external appearance of a structural member can be improved.

When the adhesive is injected from the inlet 6 into the hollow portion 5 ', the air in the hollow portion 5' and the connector insertion portion 28 is discharged from the air vent portion 29, and the adhesive injected into the hollow portion 5 'is discharged. It is discharged from the outlet 7 ′, and an adhesive is filled between the outer peripheral surface of the body portion 24 of the connector 20 and the peripheral wall of the connector insertion portion 28. Further, when the adhesive is filled between the outer peripheral surface of the connector 20 and the peripheral wall of the connector insertion portion 28, the adhesive overflows from the air vent portion 29. Therefore, the adhesive overflowing from the air vent portion 29 is confirmed and bonded. After the injection of the agent is completed, the projecting portion 31a of the embedded material 31 is fitted into the injection port 6, the embedded material 31 is embedded in the seat portion 30, and the structural member 26a and the structural member 26b are consolidated.
Here, as the adhesive, an epoxy resin-based adhesive, a polyurethane-based adhesive, a vinyl acetate resin-based adhesive, or the like is used.
In addition, the use number of the joining tools 20 is arbitrarily changed by the magnitude | size of the structural member etc. to join. In addition, when the number of the bonding tools 20 used is large, the load can be distributed, the bonding tools 20 can be downsized, the cross-sectional defects of the structural members can be reduced, and the bonding strength can be improved.
