Description

本発明は、木質材料等からなる第１建築部材の接合面と第２建築部材の接合面を接合するための建築部材の接合構造、その接合構造を備えた建築構造体、及びその接合構造の施工方法に関する。 The present invention relates to a joining structure for building components for joining the joining surface of a first building component made of wood material or the like to the joining surface of a second building component, an architectural structure having the joining structure, and a construction method for the joining structure.

近年、木造建築の分野においては、グルードインロッド（ＧＩＲ）を用いた建築部材の接合構造が開発されている。グルードインロッド方式の建築部材の接合構造には、全ネジタイプ又は異形鉄筋タイプの定着部材と、エポキシ樹脂を主成分とした硬化接着剤とが併用される。 In recent years, in the field of wooden construction, a joining structure for building components using glued-in rods (GIR) has been developed. In joining structures for building components using the glued-in rod method, a fully threaded or deformed rebar type fixing member is used in combination with a hardening adhesive whose main component is epoxy resin.

グルードインロッド方式の建築部材の接合構造を施工する際には、現場において、第１建築部材の接合面側に形成された第１接合穴に定着部材の一端側を挿入すると共に、第２建築部材の接合面側に形成された第２接合穴に定着部材の他端側を挿入する。そして、第１建築部材の第１接合穴及び第２建築部材の第２接合穴に硬化接着剤を注入して、硬化接着剤を硬化させる。これにより、第１建築部材の接合面と第２建築部材の接合面を接合して、建築部材の接合構造を施工することができる。 When constructing a joining structure for building components using the glued-in rod method, one end of the fixing member is inserted into a first joining hole formed on the joining surface side of the first building component at the site, and the other end of the fixing member is inserted into a second joining hole formed on the joining surface side of the second building component. Then, hardening adhesive is injected into the first joining hole of the first building component and the second joining hole of the second building component, and the hardening adhesive is allowed to harden. This allows the joining surface of the first building component to be joined to the joining surface of the second building component, and the joining structure for the building components to be constructed.

なお、本発明に関連する先行技術として特許文献１に示すものがある。 Note that prior art related to the present invention is shown in Patent Document 1.

ところで、グルードインロッド方式の建築部材の接合構造は、前述のように、硬化接着剤を注入する湿式工法によって施工されているため、硬化接着剤の注入に手間がかかり、硬化接着剤の注入後に硬化接着剤の一定の養生期間を必要とする。また、硬化接着剤の養生期間中においては、建築構造体をサポート材や支保工によって保持する必要がある。そのため、グルードインロッド方式の建築部材の接合構造を備えた建築構造体の工期が長くなると共に、その建築構造体の施工コストが増大するという問題がある。 As mentioned above, the joint structure of architectural components using the glued-in rod method is constructed using a wet construction method in which a hardened adhesive is injected, which requires a lot of work to inject the hardened adhesive, and a certain period of time for the hardened adhesive to cure after injection. In addition, during the period for curing the hardened adhesive, the architectural structure needs to be supported by support materials and shoring. This results in problems of longer construction periods for architectural structures equipped with a joint structure of architectural components using the glued-in rod method, and increased construction costs for the architectural structure.

接合部である第１建築部材の接合面と第２建築部材の接合面が定着部材と硬化接着剤によって強固に接合されているため、建築構造体を解体する際には、接合部の接合状態を解除できず、建築部材（第１建築部材及び第２建築部材）における接合部から外れた部位を切断する必要がある。そのため、グルードインロッド方式の建築部材の接合構造を備えた建築構造体の解体が非常に厄介であり、解体後の建築部材等をそのまま再利用できないという問題がある。 Because the joint surface of the first building component and the joint surface of the second building component, which are the joints, are firmly joined by the fixing member and hardening adhesive, when dismantling the architectural structure, the joints cannot be released and it is necessary to cut off the parts of the architectural components (the first building component and the second building component) that are separated from the joints. For this reason, dismantling an architectural structure that has a glued-in rod type joint structure for architectural components is extremely difficult, and there is a problem in that the architectural components, etc., cannot be reused as they are after dismantling.

そこで、本発明は、建築構造体の工期の短縮及び施工コストの削減を図りつつ、建築構造体の解体を簡単にしかつ解体後の建築部材等をそのまま再利用できる、建築部材の接合構造等を提供することを目的とする。 The present invention aims to provide a joining structure for architectural components that can shorten the construction period and reduce construction costs of architectural structures, while simplifying the dismantling of architectural structures and allowing architectural components to be reused as they are after dismantling.

（第１実施形態）
図１に示すように、第１実施形態に係るラーメン構造体１０は、中大規模の木造建築物に用いられる建築構造体である。ラーメン構造体１０は、コンクリートからなる床部材（基礎）１２と、床部材１２に立設されかつ木質材料，コンクリート（鉄筋コンクリートを含む），石材等からなる複数の柱部材１４と、隣接する梁部材１６間に設けられかつ木質材料からなる梁部材１６とを備えている。 First Embodiment
As shown in Fig. 1, the rigid frame structure 10 according to the first embodiment is an architectural structure used for medium- to large-scale wooden buildings. The rigid frame structure 10 includes a floor member (foundation) 12 made of concrete, a plurality of column members 14 standing on the floor member 12 and made of wood material, concrete (including reinforced concrete), stone material, etc., and beam members 16 arranged between adjacent beam members 16 and made of wood material.

図１から図３に示すように、ラーメン構造体１０は、第１建築部材としての柱部材１４の接合面１４ｐと第２建築部材としての梁部材１６の接合面１６ｐを接合するための複数のグルードインロッド方式の建築部材の接合構造１８を備えている。グルードインロッド方式の建築部材の接合構造１８は、高い初期剛性及び十分な靱性性能を持っている。そして、建築部材の接合構造１８の具体的な構成は、次の通りである。 As shown in Figures 1 to 3, the rigid frame structure 10 is provided with a plurality of glued-in rod type building component joint structures 18 for joining the joint surface 14p of the column member 14 as the first building component and the joint surface 16p of the beam member 16 as the second building component. The glued-in rod type building component joint structures 18 have high initial rigidity and sufficient toughness performance. The specific configuration of the building component joint structures 18 is as follows:

図２及び図３に示すように、柱部材１４の接合面１４ｐ側には、水平方向に延びた複数の嵌合溝１４ｇが形成されており、柱部材１４の各嵌合溝１４ｇの底面（奥面）側には、第１接合穴１４ｈが形成されている。柱部材１４の各嵌合溝１４ｇの底面側は、柱部材１４の接合面１４ｐ側の一部である。また、柱部材１４の各第１接合穴１４ｈには、全ネジタイプの棒状の第１定着部材２０がエポキシ樹脂等を主成分とした硬化接着剤Ｂの接着作用によって定着されている。各第１定着部材２０は、鋼材からなり、柱部材１４の嵌合溝１４ｇの底面に対して突出している。各第１定着部材２０は、その突出端側（先端側）に、第１固定ネジ部２０ｓを有している。 2 and 3, a plurality of fitting grooves 14g extending horizontally are formed on the joint surface 14p side of the column member 14, and a first connecting hole 14h is formed on the bottom surface (rear surface) side of each fitting groove 14g of the column member 14. The bottom surface side of each fitting groove 14g of the column member 14 is a part of the joint surface 14p side of the column member 14. In addition, a fully threaded rod-shaped first fixing member 20 is fixed to each first connecting hole 14h of the column member 14 by the adhesive action of a hardening adhesive B mainly composed of epoxy resin or the like. Each first fixing member 20 is made of steel and protrudes from the bottom surface of the fitting groove 14g of the column member 14. Each first fixing member 20 has a first fixing screw portion 20s on its protruding end side (tip side).

なお、建築部材の接合構造１８が全ネジタイプの第１定着部材２０を用いる代わりに、中空ボルトタイプの第１定着部材（図示省略）又は異形鉄筋タイプの第１定着部材（図示省略）を用いてもよい。 In addition, instead of using a full-thread type first fixing member 20 for the joining structure 18 of the building components, a hollow bolt type first fixing member (not shown) or a deformed bar type first fixing member (not shown) may be used.

梁部材１６の接合面１６ｐ側の複数の角部には、段部１６ｄがそれぞれ形成されており、梁部材１６の各段部１６ｄの段差面（段面）側には、第２接合穴１６ｈが形成されている。梁部材１６の各段部１６ｄの段差面側は、梁部材１６の接合面１６ｐ側の一部である。また、梁部材１６の各第２接合穴１６ｈには、中空ボルトタイプの棒状の第２定着部材２２がエポキシ樹脂等を主成分とした硬化接着剤Ｂの接着作用によって定着されている。各第２定着部材２２は、鋼材からなり、梁部材１６の各段部１６ｄの段差面に対して突出している。各第２定着部材２２は、その突出端側に、第２固定ネジ部２２ｓを有している。 Steps 16d are formed at each of the corners on the joint surface 16p side of the beam member 16, and second joint holes 16h are formed on the step surface (step surface) side of each step 16d of the beam member 16. The step surface side of each step 16d of the beam member 16 is part of the joint surface 16p side of the beam member 16. In addition, a hollow bolt type rod-shaped second fixing member 22 is fixed to each second joint hole 16h of the beam member 16 by the adhesive action of hardening adhesive B whose main component is epoxy resin or the like. Each second fixing member 22 is made of steel and protrudes from the step surface of each step 16d of the beam member 16. Each second fixing member 22 has a second fixing screw portion 22s on its protruding end side.

各第２定着部材２２は、第２固定ネジ部２２ｓよりも基端側に、第２定着部材２２の長手方向の靱性（伸び）を確保した靱性部２２ｔを有している。各靱性部２２ｔに対する硬化接着剤Ｂの付着力は、各第２定着部材２２の基端側部分に対する硬化接着剤Ｂの付着力よりも十分に小さく設定されている。そして、各第２定着部材２２は、靱性部２２ｔ以外の部位（各第２定着部材２２の基端側部分及び第２固定ネジ部２２ｓを含む）が破断する前に、靱性部２２ｔが伸びて破断するように構成されている。これにより、建築部材の接合構造１８は十分な靱性性能及び安定した破壊強度を持つことができる。 Each second fixing member 22 has a toughness portion 22t that ensures the toughness (elongation) of the second fixing member 22 in the longitudinal direction on the base end side of the second fixing screw portion 22s. The adhesion force of the hardened adhesive B to each toughness portion 22t is set to be sufficiently smaller than the adhesion force of the hardened adhesive B to the base end portion of each second fixing member 22. Each second fixing member 22 is configured so that the toughness portion 22t stretches and breaks before the portions other than the toughness portion 22t (including the base end portion of each second fixing member 22 and the second fixing screw portion 22s) break. This allows the joining structure 18 of the building components to have sufficient toughness performance and stable breaking strength.

なお、建築部材の接合構造１８が中空ボルトタイプの第２定着部材２２を用いる代わりに、全ネジタイプの第２定着部材（図示省略）又は異形鉄筋タイプの第２定着部材（図示省略）を用いてもよい。 In addition, instead of using a hollow bolt type second fixing member 22 for the joining structure 18 of the building components, a fully threaded type second fixing member (not shown) or a deformed bar type second fixing member (not shown) may be used.

図１から図４に示すように、梁部材１６の各段部１６ｄには、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合するための箱型の接合金具２４が設けられている。各接合金具２４は、鋼材からなり、梁部材１６の接合面１６ｐから突出している。各接合金具２４における梁部材１６の接合面１６ｐから突出した部分は、柱部材１４の各嵌合溝１４ｇに嵌合する。また、各接合金具２４は、第２定着部材２２の第２固定ネジ部２２ｓに螺合して固定された矩形の第１金具接合部２４ａを有している。各接合金具２４は、第１金具接合部２４ａに第２定着部材２２の長手方向に対向して配置された矩形の第２金具接合部２４ｂを有しており、第２金具接合部２４ｂには、第１定着部材２０の第１固定ネジ部２０ｓを挿通させるための挿通穴２４ｈが形成されている。更に、各接合金具２４は、第１金具接合部２４ａと第２金具接合部２４ｂと間に連結するように設けられた４つの金具連結部２４ｃを有しており、４つの金具連結部２４ｃは、第１金具接合部２４ａ（第２金具接合部２４ｂ）の周方向に間隔を置いて配置されている。 1 to 4, each step 16d of the beam member 16 is provided with a box-shaped metal fitting 24 for joining the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16. Each metal fitting 24 is made of steel and protrudes from the joint surface 16p of the beam member 16. The portion of each metal fitting 24 protruding from the joint surface 16p of the beam member 16 fits into each fitting groove 14g of the column member 14. Each metal fitting 24 has a rectangular first metal fitting joint 24a that is screwed and fixed to the second fixing screw portion 22s of the second fixing member 22. Each metal fitting 24 has a rectangular second metal fitting joint 24b that is arranged opposite the first metal fitting joint 24a in the longitudinal direction of the second fixing member 22, and the second metal fitting joint 24b has an insertion hole 24h for inserting the first fixing screw portion 20s of the first fixing member 20. Furthermore, each connecting metal fitting 24 has four metal fitting connecting portions 24c that are provided to connect between the first metal fitting joint portion 24a and the second metal fitting joint portion 24b, and the four metal fitting connecting portions 24c are spaced apart in the circumferential direction of the first metal fitting joint portion 24a (second metal fitting joint portion 24b).

各第１定着部材２０の第１固定ネジ部２０ｓには、高ナット２６が螺合して設けられている。各高ナット２６は、柱部材１４の接合面１４ｐと接合金具２４の第２金具接合部２４ｂの間に配置されており、各接合金具２４の第２金具接合部２４ｂに面接触する。また、各高ナット２６には、各高ナット２６と協働して各接合金具２４の第２金具接合部２４ｂを挟持する固定ボルト２８が螺合して設けられている。換言すれば、各第１定着部材２０の第１固定ネジ部２０ｓには、固定ボルト２８が高ナット２６を介して間接的に螺合して設けられている。各固定ボルト２８は、各接合金具２４内に配置されており、メガネレンチ等の締付工具（図示省略）によって各接合金具２４の側方から締付可能に構成されている。ここで、各高ナット２６及び各固定ボルト２８は、それぞれ、各接合金具２４を各第１定着部材２０に対して固定するための締結部材に相当する。 A high nut 26 is screwed into the first fixing screw portion 20s of each first fixing member 20. Each high nut 26 is disposed between the joint surface 14p of the column member 14 and the second fitting joint portion 24b of the connecting fitting 24, and is in surface contact with the second fitting joint portion 24b of each connecting fitting 24. A fixing bolt 28 is screwed into each high nut 26 to clamp the second fitting joint portion 24b of each connecting fitting 24 in cooperation with each high nut 26. In other words, the fixing bolt 28 is indirectly screwed into the first fixing screw portion 20s of each first fixing member 20 via the high nut 26. Each fixing bolt 28 is disposed in each connecting fitting 24 and is configured to be tightened from the side of each connecting fitting 24 by a tightening tool (not shown) such as a wrench. Here, each high nut 26 and each fixing bolt 28 correspond to a fastening member for fixing each connecting fitting 24 to each first fixing member 20.

図１及び図５に示すように、ラーメン構造体１０は、床部材１２の接合面（上面）１２ｍと柱部材１４の接合面（下端面）１４ｍを接合するための複数のグルードインロッド方式の建築部材の接合構造３０を備えている。グルードインロッド方式の建築部材の接合構造３０は、高い初期剛性及び靱性性能を持っている。そして、建築部材の接合構造３０の具体的な構成は、次の通りである。 As shown in Figures 1 and 5, the rigid frame structure 10 is equipped with multiple glued-in rod type building component joint structures 30 for joining the joint surface (upper surface) 12m of the floor member 12 and the joint surface (lower end surface) 14m of the column member 14. The glued-in rod type building component joint structures 30 have high initial rigidity and toughness performance. The specific configuration of the building component joint structures 30 is as follows.

図５に示すように、床部材１２の接合面１２ｍ側には、複数のアンカーボルト３２が固定（定着）されている。各アンカーボルト３２は、鋼材からなり、床部材１２の接合面１２ｍから突出している。また、各アンカーボルト３２は、その突出端側（先端側）に、固定ネジ部３２ｓを有している。 As shown in FIG. 5, a number of anchor bolts 32 are fixed (anchored) to the joining surface 12m side of the floor member 12. Each anchor bolt 32 is made of steel and protrudes from the joining surface 12m of the floor member 12. Each anchor bolt 32 also has a fixing screw portion 32s on its protruding end side (tip side).

柱部材１４の接合面１４ｍ側の複数の角部には、段部１４ｄがそれぞれ形成されており、柱部材１４の各段部１４ｄの段差面（段面）には、接合穴１４ｖが形成されている。また、柱部材１４の各接合穴１４ｖには、中空ボルトタイプの棒状の定着部材３４がエポキシ樹脂等を主成分とした硬化接着剤Ｂの接着作用によって定着されている。各定着部材３４は、鋼材からなり、柱部材１４の各段部１４ｄの段差面に対して突出している。各定着部材３４は、その突出端側に、固定ネジ部３４ｓを有している。 Steps 14d are formed at each of the multiple corners on the joint surface 14m side of the pillar member 14, and a joint hole 14v is formed in the step surface (step surface) of each step 14d of the pillar member 14. A hollow bolt-type rod-shaped fixing member 34 is fixed to each joint hole 14v of the pillar member 14 by the adhesive action of hardening adhesive B whose main component is epoxy resin or the like. Each fixing member 34 is made of steel and protrudes from the step surface of each step 14d of the pillar member 14. Each fixing member 34 has a fixing screw portion 34s on its protruding end side.

各定着部材３４は、固定ネジ部３４ｓよりも基端側に、定着部材３４の長手方向の靱性（伸び）を確保した靱性部３４ｔを有している。各靱性部３４ｔに対する硬化接着剤Ｂの付着力は、各定着部材３４の基端側部分に対する硬化接着剤Ｂの付着力よりも十分に小さく設定されている。そして、各定着部材３４は、靱性部３４ｔ以外の部位（各定着部材３４の基端側部分及び固定ネジ部３４ｓを含む）が破断する前に、靱性部３４ｔが伸びて破断するように構成されている。これにより、建築部材の接合構造３０は十分な靱性性能及び安定した破壊強度を持つことができる。 Each fixing member 34 has a tough portion 34t on the base end side of the fixing screw portion 34s, which ensures the toughness (elongation) of the fixing member 34 in the longitudinal direction. The adhesion force of the hardened adhesive B to each tough portion 34t is set to be sufficiently smaller than the adhesion force of the hardened adhesive B to the base end portion of each fixing member 34. Each fixing member 34 is configured so that the tough portion 34t stretches and breaks before the portions other than the tough portion 34t (including the base end portion of each fixing member 34 and the fixing screw portion 34s) break. This allows the joining structure 30 of the building members to have sufficient toughness performance and stable breaking strength.

なお、建築部材の接合構造３０が中空ボルトタイプの定着部材３４を用いる代わりに、全ネジタイプの定着部材（図示省略）又は異形鉄筋タイプの定着部材（図示省略）を用いてもよい。 In addition, instead of using hollow bolt type fixing members 34, the joining structure 30 of the building components may use fully threaded fixing members (not shown) or deformed bar type fixing members (not shown).

図４及び図５に示すように、柱部材１４の各段部１４ｄには、床部材１２の接合面１２ｍと柱部材１４の接合面１４ｍを接合するための箱型の接合金具３６が設けられており、各接合金具３６は、鋼材からなる。また、各接合金具３６は、定着部材３４の固定ネジ部３４ｓに螺合して固定された矩形の第１金具接合部３６ａを有している。各接合金具３６は、第１金具接合部３６ａに定着部材３４の長手方向に対向して配置された矩形の第２金具接合部３６ｂを有しており、第２金具接合部３６ｂには、アンカーボルト３２の固定ネジ部３２ｓを挿通させるための挿通穴３６ｈが形成されている。各接合金具３６の第２金具接合部３６ｂ側の側面は、柱部材１４の接合面１４ｍと同一平面上に位置している。更に、各接合金具３６は、第１金具接合部３６ａと第２金具接合部３６ｂと間に連結するように設けられた４つの金具連結部３６ｃを有しており、４つの金具連結部３６ｃは、第１金具接合部３６ａ（第２金具接合部３６ｂ）の周方向に間隔を置いて配置されている。 4 and 5, each step 14d of the column member 14 is provided with a box-shaped metal fitting 36 for joining the joint surface 12m of the floor member 12 and the joint surface 14m of the column member 14, and each metal fitting 36 is made of steel. Each metal fitting 36 has a rectangular first metal fitting joint 36a that is screwed into the fixing screw portion 34s of the fixing member 34 and fixed. Each metal fitting 36 has a rectangular second metal fitting joint 36b that is arranged opposite the first metal fitting joint 36a in the longitudinal direction of the fixing member 34, and the second metal fitting joint 36b has an insertion hole 36h for inserting the fixing screw portion 32s of the anchor bolt 32. The side surface of each metal fitting 36 on the second metal fitting joint 36b side is located on the same plane as the joint surface 14m of the column member 14. Furthermore, each connecting fitting 36 has four fitting connecting portions 36c that are provided to connect between the first fitting joint portion 36a and the second fitting joint portion 36b, and the four fitting connecting portions 36c are spaced apart in the circumferential direction of the first fitting joint portion 36a (second fitting joint portion 36b).

各アンカーボルト３２の固定ネジ部３２ｓには、床部材１２と協働して接合金具３６の第２金具接合部３６ｂを挟持する固定ナット３８が螺合して設けられている。各固定ナット３８は、各接合金具３６内に配置されており、メガネレンチ等の締付工具（図示省略）によって各接合金具３６の側方から締付可能に構成されている。 A fixing nut 38 is screwed onto the fixing threaded portion 32s of each anchor bolt 32, which cooperates with the floor member 12 to clamp the second fitting joint portion 36b of the connecting fitting 36. Each fixing nut 38 is disposed within each connecting fitting 36 and is configured to be tightened from the side of each connecting fitting 36 with a tightening tool (not shown) such as a wrench.

続いて、図２及び図６を参照しながら、グルードインロッド方式の建築部材の接合構造１８を施工するための施工方法（建築構造の接合構造の施工方法）について説明する。 Next, with reference to Figures 2 and 6, we will explain the construction method for constructing the joint structure 18 of architectural components using the glued-in rod method (construction method for the joint structure of an architectural structure).

図６（ａ）に示すように、各第１定着部材２０の第１固定ネジ部２０ｓに高ナット２６を螺合させて取付ける。次に、図６（ｂ）に示すように、各第１定着部材２０の第１固定ネジ部２０ｓを各接合金具２４の挿通穴２４ｈに挿通させ、かつ各接合金具２４における前記突出した部分を柱部材１４の各嵌合溝１４ｇに嵌合させて、梁部材１６の接合面１６ｐを柱部材１４の接合面１４ｐに接触させる。その後、各高ナット２６に螺合した各固定ボルト２８を締付工具によって締め付けることにより、各固定ボルト２８の頭部と各高ナット２６の協働によって各接合金具２４の第２金具接合部２４ｂを挟持して、各接合金具２４を第１定着部材２０に対して固定する。これにより、図２に示すように、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合して、建築部材の接合構造１８を施工することができる。 As shown in FIG. 6(a), the high nuts 26 are screwed onto the first fixing screw portion 20s of each first fixing member 20 to attach it. Next, as shown in FIG. 6(b), the first fixing screw portion 20s of each first fixing member 20 is inserted into the insertion hole 24h of each connecting metal fitting 24, and the protruding portion of each connecting metal fitting 24 is fitted into each fitting groove 14g of the column member 14, so that the joint surface 16p of the beam member 16 comes into contact with the joint surface 14p of the column member 14. Then, the fixing bolts 28 screwed into each high nut 26 are tightened with a tightening tool, so that the heads of the fixing bolts 28 and the high nuts 26 cooperate to clamp the second metal fitting joint portion 24b of each connecting metal fitting 24, and the connecting metal fittings 24 are fixed to the first fixing member 20. As a result, as shown in FIG. 2, the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 are joined to construct the joint structure 18 of the building members.

続いて、第１実施形態の作用効果について説明する。 Next, the effects of the first embodiment will be explained.

前述のように、各接合金具２４は、各第２定着部材２２の第２固定ネジ部２２ｓに螺合して固定された第１金具接合部２４ａ、及び各第１定着部材２０の第１固定ネジ部２０ｓを挿通させるための挿通穴２４ｈが形成された第２金具接合部２４ｂを有している。各第１定着部材２０の第１固定ネジ部２０ｓに高ナット２６が螺合して設けられており、各高ナット２６に固定ボルト２８が螺合して設けられている。そのため、各固定ボルト２８を締め付けるだけで、各接合金具２４を各第１定着部材２０に対して固定して、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合することができる。また、各固定ボルト２８を緩めて、各固定ボルト２８の螺合状態を解除するだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐの接合状態を解除することができる。 As described above, each of the connecting fittings 24 has a first fitting joint 24a that is screwed and fixed to the second fixing screw portion 22s of each of the second fixing members 22, and a second fitting joint 24b in which an insertion hole 24h for inserting the first fixing screw portion 20s of each of the first fixing members 20 is formed. A high nut 26 is screwed and provided on the first fixing screw portion 20s of each of the first fixing members 20, and a fixing bolt 28 is screwed and provided on each of the high nuts 26. Therefore, by simply tightening each of the fixing bolts 28, each of the connecting fittings 24 can be fixed to each of the first fixing members 20, and the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be joined. In addition, by simply loosening each of the fixing bolts 28 and releasing the screwed state of each of the fixing bolts 28, the joint state of the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be released.

同じ理由により、梁部材１６に生じる引張力（接合構造１８側への引張力）は、第２定着部材２２、接合金具２４、及び固定ボルト２８を経由して第１定着部材２０側に伝達され、第１定着部材２０側によって負担される。梁部材１６に生じる圧縮力（接合構造１８への圧縮力）は、第２定着部材２２、接合金具２４、及び高ナット２６を経由して第１定着部材２０側に伝達され、第１定着部材２０側によって負担される。また、各高ナット２６のネジ込み量を調節することにより、柱部材１４に対する梁部材１４の水平方向の位置を微小調整することができる。 For the same reason, the tensile force (tensile force toward the joint structure 18) generated in the beam member 16 is transmitted to the first fixing member 20 via the second fixing member 22, the joint fitting 24, and the fixing bolt 28, and is borne by the first fixing member 20. The compressive force (compressive force toward the joint structure 18) generated in the beam member 16 is transmitted to the first fixing member 20 via the second fixing member 22, the joint fitting 24, and the high nut 26, and is borne by the first fixing member 20. In addition, by adjusting the amount of screwing of each high nut 26, the horizontal position of the beam member 14 relative to the column member 14 can be finely adjusted.

前述のように、柱部材１４の接合面１４ｐ側に水平方向に延びた複数の嵌合溝１４ｇが形成されている。各接合金具２４における梁部材１６の接合面１６ｐから突出した部分が柱部材１４の各嵌合溝１４ｇに嵌合する。そのため、柱部材１４に対する梁部材１４の上下方向の位置決めを簡単に行うことができると共に、梁部材１６に生じる剪断力は、第２定着部材２２及び接合金具２４を経由して柱部材１４の嵌合溝ｇの壁面（下側壁面）側に伝達され、柱部材１４の嵌合溝ｇの壁面（下側壁面）側によって負担される。 As described above, a plurality of fitting grooves 14g extending horizontally are formed on the joint surface 14p side of the column member 14. The portion of each connecting metal fitting 24 protruding from the joint surface 16p of the beam member 16 fits into each fitting groove 14g of the column member 14. This makes it easy to position the beam member 14 in the vertical direction relative to the column member 14, and the shear force generated in the beam member 16 is transmitted to the wall surface (lower wall surface) of the fitting groove g of the column member 14 via the second fixing member 22 and the connecting metal fitting 24, and is borne by the wall surface (lower wall surface) of the fitting groove g of the column member 14.

従って、第１実施形態によれば、各固定ボルト２８を締め付けるだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合できるため、現場における硬化接着剤Ｂの注入の手間及び硬化接着剤Ｂの養生期間を省略して、建築部材の接合構造１８を備えたラーメン構造体１０の工期を大幅に短縮することができる。 Therefore, according to the first embodiment, the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be joined simply by tightening each fixing bolt 28, eliminating the need for the labor of injecting hardened adhesive B on-site and the curing period for hardened adhesive B, and significantly shortening the construction period of the rigid frame structure 10 equipped with the joint structure 18 for the building members.

各固定ボルト２８の螺合状態を解除するだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐの接合状態を解除できるため、ラーメン構造体１０の解体を簡単になると共に、解体後の柱部材１４、梁部材１６、及び接合金具２４等をそのまま再利用することができる。 By simply releasing the screwed state of each fixing bolt 28, the joint state between the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be released, which simplifies dismantling the rigid frame structure 10 and allows the column members 14, beam members 16, and joint fittings 24, etc. to be reused as they are after dismantling.

梁部材１６に生じる引張力及び圧縮力が第１定着部材２０側によって負担され、梁部材１６に生じる剪断力が柱部材１４の嵌合溝ｇの壁面側によって負担されるため、建築部材の接合構造１８の接合耐力を十分に発揮させることができる。 The tensile and compressive forces acting on the beam member 16 are borne by the first fixing member 20, and the shear force acting on the beam member 16 is borne by the wall side of the fitting groove g of the column member 14, so that the joint strength of the joint structure 18 of the building members can be fully exerted.

柱部材１４に対する梁部材１４の水平方向の位置を微小調整することができ、柱部材１４に対する梁部材１４の上下方向の位置決めを簡単に行うことができるため、建築部材の接合構造１８の施工性を高めることができる。 The horizontal position of the beam member 14 relative to the column member 14 can be finely adjusted, and the vertical positioning of the beam member 14 relative to the column member 14 can be easily performed, improving the workability of the joining structure 18 of the building components.

（第１実施形態の変形例）
図７に示すように、第１実施形態の変形例に係るグルードインロッド方式の建築部材の接合構造１８Ａは、一部を除き、第１実施形態に係るグルードインロッド方式の建築部材の接合構造１８（図２参照）と同様の構成を有している。建築部材の接合構造１８Ａの構成のうち、建築部材の接合構造１８と異なる構成についてのみ説明する。なお、建築部材の接合構造１８Ａにおける複数の構成要素のうち、建築部材の接合構造１８における構成要素と対応するものについては、図面中に同一符号を付している。 (Modification of the first embodiment)
As shown in Fig. 7, the joint structure 18A of the building member of the glued-in rod type according to the modified example of the first embodiment has the same configuration as the joint structure 18 of the building member of the glued-in rod type according to the first embodiment (see Fig. 2), except for some parts. Only the configuration of the joint structure 18A of the building member that is different from the joint structure 18 of the building member will be described. Note that, among the multiple components of the joint structure 18A of the building member, those corresponding to the components of the joint structure 18 of the building member are given the same reference numerals in the drawings.

建築部材の接合構造１８Ａにおける各第１定着部材２０は、中空ボルトタイプである。各第１定着部材２０は、第１固定ネジ部２０ｓよりも基端側に、第１定着部材２０の長手方向の靱性を確保した靱性部２０ｔを有している。各靱性部２０ｔに対する硬化接着剤Ｂの付着力は、各第１定着部材２０の基端側部分に対する硬化接着剤Ｂの付着力よりも十分に小さく設定されている。そして、各第１定着部材２０は、靱性部２０ｔ以外の部位（各第１定着部材２０の基端側部分及び第１固定ネジ部２０ｓを含む）が破断する前に、靱性部２０ｔが伸びて破断するように構成されている。また、建築部材の接合構造１８Ａにおける各第２定着部材２２は、全ネジタイプであり、靱性部２２ｔを有していない。 Each first fixing member 20 in the joining structure 18A of the building components is a hollow bolt type. Each first fixing member 20 has a toughness portion 20t that ensures the toughness of the first fixing member 20 in the longitudinal direction on the base end side of the first fixing screw portion 20s. The adhesion force of the hardened adhesive B to each toughness portion 20t is set to be sufficiently smaller than the adhesion force of the hardened adhesive B to the base end side portion of each first fixing member 20. Each first fixing member 20 is configured so that the toughness portion 20t stretches and breaks before the portions other than the toughness portion 20t (including the base end side portion of each first fixing member 20 and the first fixing screw portion 20s) break. Each second fixing member 22 in the joining structure 18A of the building components is a full screw type and does not have a toughness portion 22t.

そして、第１実施形態の変形例においても、第１実施形態と同様の作用効果を奏する。 The modified version of the first embodiment also provides the same effects as the first embodiment.

（第２実施形態）
図８に示すように、第２実施形態に係るグルードインロッド方式の建築部材の接合構造４０は、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合するため接合構造である。建築部材の接合構造４０は、一部を除き、第１実施形態に係る建築部材の接合構造１８（図２参照）と同様の構成を有している。建築部材の接合構造４０の構成のうち、建築部材の接合構造１８と異なる構成についてのみ説明する。なお、建築部材の接合構造４０における複数の構成要素のうち、建築部材の接合構造１８における構成要素と対応するものについては、図面中に同一符号を付している。 Second Embodiment
As shown in Fig. 8, the joint structure 40 of a building component using the glued-in rod method according to the second embodiment is a joint structure for joining the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16. The joint structure 40 of a building component has the same configuration as the joint structure 18 of a building component according to the first embodiment (see Fig. 2), with some exceptions. Only the configuration of the joint structure 40 of a building component that differs from the joint structure 18 of a building component will be described. Note that, among the multiple components in the joint structure 40 of a building component, those that correspond to the components in the joint structure 18 of a building component are given the same reference numerals in the drawings.

柱部材１４の接合面１４ｐ側には、複数の第１接合穴１４ｈが形成されている。各接合金具２４の第２金具接合部２４ｂ側の側面は、梁部材１６の接合面１６ｐと同一平面上に位置している。 A number of first connection holes 14h are formed on the joint surface 14p side of the column member 14. The side surface of each joint metal fitting 24 on the second metal fitting joint portion 24b side is located on the same plane as the joint surface 16p of the beam member 16.

建築部材の接合構造４０は、各接合金具２４を各第１定着部材２０に対して固定するための締結部材として、高ナット２６及び固定ボルト２８（図２参照）の代わりに、中間ナット４２及び固定ナット４４を備えている。具体的には、各第１定着部材２０の第１固定ネジ部２０ｓには、中間ナット４２が螺合して設けられている。各中間ナット４２は、柱部材１４の接合面１４ｐと各接合金具２４の第２金具接合部２４ｂとの間に配置されおり、柱部材１４の接合面１４ｐ及び各接合金具２４の第２金具接合部２４ｂに面接触する。また、各第１定着部材２０の第１固定ネジ部２０ｓには、各中間ナット４２と協働して各接合金具２４の第２金具接合部２４ｂを挟持する固定ナット４４が螺合して設けられている。各固定ナット４４は、各接合金具２４に配置されており、メガネレンチ等の締付工具（図示省略）によって各接合金具２４の側方から締付可能に構成されている。 The joining structure 40 of the building components includes intermediate nuts 42 and fixed nuts 44 instead of the high nuts 26 and the fixing bolts 28 (see FIG. 2) as fastening members for fixing each joining metal fitting 24 to each first fixing member 20. Specifically, the intermediate nuts 42 are screwed into the first fixing screw portion 20s of each first fixing member 20. Each intermediate nut 42 is disposed between the joint surface 14p of the column member 14 and the second metal fitting joint portion 24b of each joining metal fitting 24, and is in surface contact with the joint surface 14p of the column member 14 and the second metal fitting joint portion 24b of each joining metal fitting 24. In addition, a fixed nut 44 is screwed into the first fixing screw portion 20s of each first fixing member 20, which cooperates with each intermediate nut 42 to clamp the second metal fitting joint portion 24b of each joining metal fitting 24. Each fixing nut 44 is disposed on each connecting fitting 24 and is configured to be tightened from the side of each connecting fitting 24 using a tightening tool such as a wrench (not shown).

なお、建築部材の接合構造４０の構成から中間ナット４２を省略してもよい。この場合には、各接合金具２４の第２金具接合部２４ｂ側の側面は、柱部材１４の接合面１４ｐに面接触する。 The intermediate nut 42 may be omitted from the structure 40 of the building components. In this case, the side of each connecting metal fitting 24 on the second metal fitting joint portion 24b side is in surface contact with the joint surface 14p of the pillar member 14.

続いて、図８及び図９を参照しながら、グルードインロッド方式の建築部材の接合構造４０を施工するための施工方法（建築構造の接合構造の施工方法）について説明する。 Next, with reference to Figures 8 and 9, we will explain the construction method for constructing the joint structure 40 of architectural components using the glued-in rod method (construction method for the joint structure of an architectural structure).

図９（ａ）に示すように、各第１定着部材２０の第１固定ネジ部２０ｓに中間ナット４２を螺合させて、柱部材１４の接合面１４ｐに面接触させる。次に、図９（ｂ）に示すように、各第１定着部材２０の第１固定ネジ部２０ｓを各接合金具２４の挿通穴２４ｈに挿通させて、梁部材１６の接合面１６ｐを柱部材１４の接合面１４ｐに近接させる。その後、各第１定着部材２０の第１固定ネジ部２０ｓに螺合した各固定ナット４４を締付工具によって締め付けることにより、各固定ナット４４と各中間ナット４２の協働によって各接合金具２４の第２金具接合部２４ｂを挟持して、各接合金具２４を第１定着部材２０に対して固定する。これにより、図８に示すように、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合して、建築部材の接合構造４０を施工することができる。 As shown in FIG. 9(a), the intermediate nut 42 is screwed onto the first fixing screw portion 20s of each first fixing member 20, and is brought into surface contact with the joint surface 14p of the column member 14. Next, as shown in FIG. 9(b), the first fixing screw portion 20s of each first fixing member 20 is inserted into the insertion hole 24h of each connecting metal fitting 24, and the joint surface 16p of the beam member 16 is brought close to the joint surface 14p of the column member 14. Then, the fixing nuts 44 screwed onto the first fixing screw portion 20s of each first fixing member 20 are tightened with a tightening tool, and the second metal fitting joint portion 24b of each connecting metal fitting 24 is clamped by the cooperation of the fixing nuts 44 and the intermediate nuts 42, and each connecting metal fitting 24 is fixed to the first fixing member 20. As a result, as shown in FIG. 8, the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 are joined, and the joint structure 40 of the building members can be constructed.

続いて、第２実施形態の作用効果について説明する。 Next, the effects of the second embodiment will be explained.

前述のように、各接合金具２４は、各第２定着部材２２の第２固定ネジ部２２ｓに螺合して固定された第１金具接合部２４ａ、及び各第１定着部材２０の第１固定ネジ部２０ｓを挿通させるための挿通穴２４ｈが形成された第２金具接合部２４ｂを有している。各第１定着部材２０の第１固定ネジ部２０ｓに中間ナット４２が螺合して設けられ、各中間ナット４２は、柱部材１４の接合面１４ｐと各接合金具２４の第２金具接合部２４ｂとの間に配置されている。各第１定着部材２０の第１固定ネジ部２０ｓに固定ナット４４が螺合して設けられている。そのため、各固定ナット４４を締め付けるだけで、各接合金具２４を各第１定着部材２０に対して固定して、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合することができる。また、各固定ナット４４を緩めて、各固定ナット４４の螺合状態を解除するだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐの接合状態を解除することができる。 As described above, each of the connecting fittings 24 has a first fitting joint 24a screwed and fixed to the second fixing screw portion 22s of each of the second fixing members 22, and a second fitting joint 24b in which an insertion hole 24h for inserting the first fixing screw portion 20s of each of the first fixing members 20 is formed. An intermediate nut 42 is screwed and provided on the first fixing screw portion 20s of each of the first fixing members 20, and each intermediate nut 42 is disposed between the joint surface 14p of the column member 14 and the second fitting joint portion 24b of each of the connecting fittings 24. A fixing nut 44 is screwed and provided on the first fixing screw portion 20s of each of the first fixing members 20. Therefore, by simply tightening each fixing nut 44, each of the connecting fittings 24 can be fixed to each of the first fixing members 20, and the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be joined. In addition, the joint state between the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be released simply by loosening each of the fixing nuts 44 and releasing the screwed state of each of the fixing nuts 44.

同じ理由により、梁部材１６に生じる引張力（接合構造４０側への引張力）は、第２定着部材２２、接合金具２４、及び固定ナット４４を経由して第１定着部材２０側に伝達され、第１定着部材２０側によって負担される。梁部材１６に生じる圧縮力（接合構造４０側への圧縮力）は、第２定着部材２２、接合金具２４、及び中間ナット４２を経由して第１定着部材２０側に伝達され、第１定着部材２０側によって負担される。 For the same reason, the tensile force (tensile force toward the joining structure 40) generated in the beam member 16 is transmitted to the first fixing member 20 side via the second fixing member 22, the joining metal fitting 24, and the fixing nut 44, and is borne by the first fixing member 20 side. The compressive force (compressive force toward the joining structure 40) generated in the beam member 16 is transmitted to the first fixing member 20 side via the second fixing member 22, the joining metal fitting 24, and the intermediate nut 42, and is borne by the first fixing member 20 side.

従って、第２実施形態によれば、各固定ナット４４を締め付けるだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合できるため、現場における硬化接着剤Ｂの注入の手間及び硬化接着剤Ｂの養生期間を省略して、建築部材の接合構造４０を備えたラーメン構造体等の建築構造体（図示省略）の工期を大幅に短縮することができる。 Therefore, according to the second embodiment, the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be joined simply by tightening each fixing nut 44, which eliminates the need for the labor of injecting hardened adhesive B on-site and the curing period for hardened adhesive B, and significantly shortens the construction period of an architectural structure (not shown) such as a rigid frame structure equipped with a joint structure 40 for architectural components.

各固定ナット４４の螺合状態を解除するだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐの接合状態を解除できるため、建築構造体の解体を簡単になると共に、解体後の柱部材１４、梁部材１６、及び接合金具２４等をそのまま再利用することができる。 By simply releasing the screwed state of each fixing nut 44, the joint state between the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be released, which simplifies the dismantling of the architectural structure and allows the column member 14, beam member 16, and joint fittings 24, etc. to be reused as they are after dismantling.

梁部材１６に生じる引張力及び圧縮力が第１定着部材２０側によって負担されるため、建築部材の接合構造４０の接合耐力を十分に発揮させることができる。 The tensile and compressive forces occurring in the beam member 16 are borne by the first fixing member 20, so the joint strength of the joint structure 40 of the building components can be fully exerted.

（第３実施形態）
図１０に示すように、第３実施形態に係るグルードインロッド方式の建築部材の接合構造４６は、Ｈ形鋼からなる柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合するため接合構造である。建築部材の接合構造４６は、一部を除き、第２実施形態に係るグルードインロッド方式の建築部材の接合構造４０（図８参照）と同様の構成を有している。建築部材の接合構造４６の構成のうち、建築部材の接合構造４０と異なる構成についてのみ説明する。なお、建築部材の接合構造４６における複数の構成要素のうち、建築部材の接合構造４０における構成要素と対応するものについては、図面中に同一符号を付している。 Third Embodiment
As shown in Fig. 10, the joint structure 46 of the building member of the glued-in rod method according to the third embodiment is a joint structure for joining the joint surface 14p of the column member 14 made of H-shaped steel and the joint surface 16p of the beam member 16. The joint structure 46 of the building member has the same configuration as the joint structure 40 of the building member of the glued-in rod method according to the second embodiment (see Fig. 8), except for a part. Only the configuration of the joint structure 46 of the building member that is different from the joint structure 40 of the building member will be described. Note that, among the multiple components of the joint structure 46 of the building member, those corresponding to the components of the joint structure 40 of the building member are given the same reference numerals in the drawings.

建築部材の接合構造４６においては、接合対象である柱部材１４は、Ｈ形鋼からなり、フランジ部１４ｆを有している。柱部材１４の接合面１４ｐ側のフランジ部１４ｆには、複数の取付穴１４ｂが貫通して形成されている。 In the joining structure 46 for building components, the column member 14 to be joined is made of H-shaped steel and has a flange portion 14f. A number of mounting holes 14b are formed through the flange portion 14f on the joining surface 14p side of the column member 14.

建築部材の接合構造４６は、複数の中間ナット４２及び複数の固定ナット４４（図８参照）を備える代わりに、複数の接合ボルト４８及び複数の固定ナット５０を備えている。具体的には、柱部材１４の各取付穴１４ｂには、接合ボルト４８が挿通して設けられている。各接合金具２４の挿通穴２４ｈは、各接合ボルト４８を挿通させる。また、各接合ボルト４８には、各接合ボルト４８の頭部と協働して接合金具２４を柱部材１４の接合面１４ｐに対して固定する固定ナット５０が螺合して設けられている。 Instead of having multiple intermediate nuts 42 and multiple fixing nuts 44 (see FIG. 8), the joining structure 46 of the building components has multiple joining bolts 48 and multiple fixing nuts 50. Specifically, a joining bolt 48 is inserted into each mounting hole 14b of the column member 14. The joining bolts 48 are inserted into the insertion holes 24h of each joining metal fitting 24. Each joining bolt 48 is also provided with a fixing nut 50 screwed into it, which cooperates with the head of each joining bolt 48 to fix the joining metal fitting 24 to the joining surface 14p of the column member 14.

続いて、図１０及び図１１を参照しながら、グルードインロッド方式の建築部材の接合構造４６を施工するための施工方法（建築構造の接合構造の施工方法）について説明する。 Next, a construction method for constructing a joint structure 46 for architectural components using the glued-in rod method (construction method for a joint structure for an architectural structure) will be described with reference to Figures 10 and 11.

図１１（ａ）（ｂ）に示すように、梁部材１６の接合面１６ｐを柱部材１４の接合面１４ｐに接触させる。次に、図１１（ｂ）に示すように、各接合ボルト４８を各接合金具２４の挿通穴２４ｈに挿通した状態で、柱部材１４の各取付穴１４ｂに取付ける。そして、各接合ボルト４８に螺合した各固定ナット５０を締付工具によって締め付けることにより、各固定ナット５０と各接合ボルト４８の頭部の協働によって各接合金具２４の第２金具接合部２４ｂを挟持して、各接合金具２４を梁部材１６の接合面１６ｐに対して固定する。これにより、図１０に示すように、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合して、建築部材の接合構造４６を施工することができる。 11(a) and (b), the joint surface 16p of the beam member 16 is brought into contact with the joint surface 14p of the column member 14. Next, as shown in FIG. 11(b), each of the joint bolts 48 is inserted into the insertion holes 24h of each of the joint fittings 24 and attached to each of the mounting holes 14b of the column member 14. Then, by tightening each of the fixing nuts 50 screwed onto each of the joint bolts 48 with a tightening tool, the second fitting joint portion 24b of each of the joint fittings 24 is clamped by the cooperation of each of the fixing nuts 50 and the heads of each of the joint bolts 48, and each of the joint fittings 24 is fixed to the joint surface 16p of the beam member 16. As a result, as shown in FIG. 10, the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 are joined to construct the joint structure 46 of the building members.

続いて、第３実施形態の作用効果について説明する。 Next, the effects of the third embodiment will be described.

前述のように、各接合金具２４は、各第２定着部材２２の第２固定ネジ部２２ｓに螺合して固定された第１金具接合部２４ａ、及び各接合ボルト４８を挿通させるための挿通穴２４ｈが形成された第２金具接合部２４ｂを有している。柱部材１４の各取付穴１４ｂに接合ボルト４８が挿通して設けられており、各接合ボルト４８に固定ナット５０が螺合して設けられている。そのため、各固定ナット５０を締め付けるだけで、各接合金具２４を梁部材１６の接合面１６ｐに対して固定して、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合することができる。また、各固定ナット５０を緩めて、各固定ナット５０の螺合状態を解除するだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐの接合状態を解除することができる。 As described above, each connecting metal fitting 24 has a first metal fitting connecting portion 24a that is screwed and fixed to the second fixing screw portion 22s of each second fixing member 22, and a second metal fitting connecting portion 24b in which an insertion hole 24h for inserting each connecting bolt 48 is formed. A connecting bolt 48 is inserted into each mounting hole 14b of the column member 14, and a fixing nut 50 is screwed and provided on each connecting bolt 48. Therefore, by simply tightening each fixing nut 50, each connecting metal fitting 24 can be fixed to the connecting surface 16p of the beam member 16, and the connecting surface 14p of the column member 14 and the connecting surface 16p of the beam member 16 can be joined. In addition, by simply loosening each fixing nut 50 and releasing the screwed state of each fixing nut 50, the joining state of the connecting surface 14p of the column member 14 and the connecting surface 16p of the beam member 16 can be released.

従って、第２実施形態によれば、各固定ナット５０を締め付けるだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐを接合できるため、現場における硬化接着剤Ｂの注入の手間及び硬化接着剤Ｂの養生期間を省略して、建築部材の接合構造４６を備えたラーメン構造体等の建築構造体（図示省略）の工期を大幅に短縮することができる。 Therefore, according to the second embodiment, the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be joined simply by tightening each fixing nut 50, eliminating the need for the labor of injecting hardened adhesive B on-site and the curing period for hardened adhesive B, and thus significantly shortening the construction period of an architectural structure (not shown) such as a rigid frame structure equipped with a joint structure 46 for architectural members.

各固定ナット５０の螺合状態を解除するだけで、柱部材１４の接合面１４ｐと梁部材１６の接合面１６ｐの接合状態を解除できるため、建築構造体の解体を簡単になると共に、解体後の柱部材１４、梁部材１６、及び接合金具２４等をそのまま再利用することができる。 By simply releasing the screwed state of each fixing nut 50, the joint state between the joint surface 14p of the column member 14 and the joint surface 16p of the beam member 16 can be released, which simplifies the dismantling of the architectural structure and allows the column member 14, beam member 16, and joint fittings 24, etc. to be reused as they are after dismantling.

なお、本発明は、前述の実施形態の説明に限られるものでなく、例えば、次のように適宜の変更を行うことにより、様々な態様で実施可能である。 The present invention is not limited to the above-described embodiment, but can be implemented in various forms by making appropriate modifications, for example, as follows:

柱部材１４を第１建築部材としかつ梁部材１６を第２建築部材とする代わりに、梁部材１６を第１建築部材としかつ柱部材１４を第２建築部材としてもよい。この場合には、接合金具２４は柱部材１４の段部に設けられる。また、梁部材１６を第２建築部材とする代わりに、桁部材（図示省略）を第２建築部材としてもよい。 Instead of the column member 14 being the first building member and the beam member 16 being the second building member, the beam member 16 may be the first building member and the column member 14 may be the second building member. In this case, the joint fitting 24 is provided on the step of the column member 14. Also, instead of the beam member 16 being the second building member, a girder member (not shown) may be the second building member.

そして、本発明に包含される権利範囲は、前述の実施形態に限定されないものである。 The scope of the rights encompassed by this invention is not limited to the above-mentioned embodiments.
