Description

本発明は、木質建築部材同士や、木質建築部材とコンクリートや石材、木質建築部材及び鉄骨部材等を接合するための接合治具を用いた接合構造に関する。   The present invention relates to a joining structure using joining jigs for joining wood building members, wood building members and concrete, stone, wood building members, steel members and the like.

近年、「公共建築物木材利用促進法」などが施行され、中大規模の木造建築物が建設されるようになってきている。この中大規模の木造建築物においては、接合部に高い性能が要求されることとなり、高い初期剛性、十分な靱性、安定した破壊強度を持ち、且つ耐火性能の高い接合金物を開発することが求められている。   In recent years, the “Public Building Timber Utilization Promotion Law” has been enforced, and medium- and large-scale wooden buildings have been constructed. In this medium-sized and large-scale wooden building, high performance is required for the joint, and it is necessary to develop a joint hardware having high initial rigidity, sufficient toughness, stable fracture strength, and high fire resistance. It has been demanded.

特許文献１〜３にしめすように従来の一般的な接合構造として、木質建築部材において高い接合性能を持つ、全ネジボルトや異形鉄筋と接着剤を併用した方式、ラグスクリュー方式が知られている。   As shown in Patent Documents 1 to 3, as a conventional general joint structure, a method using a combination of all screw bolts, deformed reinforcing bars and an adhesive having a high joint performance in a wooden building member, and a lag screw method are known.

特開平５−３３１９１９号公報Japanese Patent Laid-Open No. 5-331919 特開２０１３−１４９４０号公報JP 2013-14940 A 特開２００８−２８０７８６号公報JP 2008-280786 A

しかしながら、特許文献１の接合構造では、中空式の全ネジボルトと接着剤を併用し、木質建築部材を接合する構造であるが、接合部の破壊は脆性的であり、破壊強度は木質建築部材の材質が影響し、破壊強度にばらつきが生じてしまうという問題があった。   However, the joint structure of Patent Document 1 is a structure in which a hollow building screw bolt and an adhesive are used together to join a wooden building member. There was a problem that the material was affected and the fracture strength varied.

また、特許文献２の接続構造では、ラグスクリューボルトと摩擦抵抗を生じる金物により構成される接合方式である。しかし、この接合方式によれば、ある程度の剛性と靱性は確保することができるが、特許文献１の接合構造と比較すると接合強度、初期剛性は特許文献１に劣るという問題がある。また、接合部に摩擦抵抗を生じる金物が露出するため、美観を損なうとともに、耐火性能に劣っている。   Moreover, in the connection structure of patent document 2, it is a joining system comprised with the hardware which produces a lag screw bolt and frictional resistance. However, according to this joining method, a certain degree of rigidity and toughness can be secured, but there is a problem that the joining strength and the initial rigidity are inferior to those of Patent Document 1 as compared with the joint structure of Patent Document 1. Moreover, since the metal object which produces frictional resistance is exposed to a junction part, while deteriorating aesthetics, it is inferior to fireproof performance.

さらに、特許文献３の接続構造では、鋼材に変形性能を持たせるため、異形鉄筋などの一部を切削し、断面積を小さくした変形部を持つロッドと接着剤とを併用した接合方式であり、高い接合強度と剛性及び靱性を有する接合方式である。しかし、この接合方式では、変形部はあくまでも靱性を持たせるためのもので、鋼材の降伏耐力で断面積が設定されている。また、変形部を形成するために鋼材を切削しなければならず、コスト等が掛かってしまうという課題があった。   Furthermore, in the connection structure of Patent Document 3, in order to give the steel material deformation performance, it is a joining method in which a part of a deformed reinforcing bar or the like is cut and a rod having a deformed portion with a reduced cross-sectional area and an adhesive are used in combination. This is a bonding method having high bonding strength, rigidity and toughness. However, in this joining method, the deformed portion is only for providing toughness, and the cross-sectional area is set by the yield strength of the steel material. Moreover, in order to form a deformation | transformation part, you had to cut steel materials, and there existed a subject that cost etc. will start.

そこで、本発明は、木質建築部材を接合する接合部において、高い初期剛性、十分な靱性、安定した破壊強度、且つ、コストを抑えることのできる接合構造を提供することを目的とする。   Therefore, an object of the present invention is to provide a joint structure that can suppress high initial rigidity, sufficient toughness, stable fracture strength, and cost in a joint portion that joins wooden building members.

上述した課題を解決するため、本発明は、少なくとも２つ以上の建築部材を接合する接合構造であって、前記建築部材には、接合治具が挿入される治具挿入孔が設けられ、前記治具挿入孔には、接合治具が挿入されるとともに、接合治具と建築部材とを固定する接着剤が充填され、前記治具挿入孔に挿入される接合治具は、円筒状の本体部と、中間軸部と、ネジ端部とを備え、前記ネジ端部は、転造ネジによって設けられていることを特徴とする。   In order to solve the above-described problem, the present invention is a joining structure for joining at least two or more building members, and the building member is provided with a jig insertion hole into which a joining jig is inserted, The jig insertion hole is filled with an adhesive for fixing the bonding jig and the building member, and the bonding jig inserted into the jig insertion hole is a cylindrical main body. Part, an intermediate shaft part, and a screw end part, and the screw end part is provided with a rolling screw.

また、前記接合治具の内周には、接着剤が注入可能な中空部を有していることを特徴とする。   In addition, the inner periphery of the joining jig has a hollow portion into which an adhesive can be injected.

さらに、前記接合治具の中間軸部には、スリット部が設けられ、前記スリット部の外径は、前記ネジ端部よりも小径に形成されていることを特徴とする。   Furthermore, the intermediate shaft portion of the joining jig is provided with a slit portion, and the outer diameter of the slit portion is formed to be smaller than the screw end portion.

さらにまた、前記建築部材には、治具挿入孔へ接着剤を注入する接着剤注入孔が形成されていることを特徴とする。   Furthermore, the building member is characterized in that an adhesive injection hole for injecting an adhesive into the jig insertion hole is formed.

加えて、前記建築部材には、接着剤注入孔から治具挿入孔へ注入された接着剤が排出される接着剤排出孔が形成されていることを特徴とする。   In addition, the building member is formed with an adhesive discharge hole for discharging the adhesive injected from the adhesive injection hole to the jig insertion hole.

本発明の特徴によれば、建築部材には、接合治具が挿入される治具挿入孔が設けられ、治具挿入孔には、接合治具が挿入されるとともに、接合治具と建築部材とを固定する接着剤が充填され、治具挿入孔に挿入される接合治具は、円筒状の本体部と、中間軸部と、ネジ端部とを備え、ネジ端部は、転造ネジによって設けられていることにより、中間軸部よりもネジ端部の径を大きくすることができ、ネジ端部の強度を中間軸部の強度よりも強固にすることができる。   According to the features of the present invention, the building member is provided with a jig insertion hole into which a joining jig is inserted, and the joining jig is inserted into the jig insertion hole, and the joining jig and the building member are inserted. The bonding jig to be inserted into the jig insertion hole is provided with a cylindrical main body portion, an intermediate shaft portion, and a screw end portion, and the screw end portion is a rolled screw. The diameter of the screw end portion can be made larger than that of the intermediate shaft portion, and the strength of the screw end portion can be made stronger than the strength of the intermediate shaft portion.

さらに、接合治具の中間軸部には、スリット部が設けられているため、接合治具の破壊強度を調整することができスリット部から破断させることができるため、接合治具の破壊強度を安定させることができる。また、接合治具はスリット部から破断するため、破断させる位置を所望の位置に設定することができ、接合治具の中間軸部によって建築部材の滑落を防止することができる。   Furthermore, since the slit part is provided in the intermediate shaft part of the joining jig, the breaking strength of the joining jig can be adjusted and broken from the slit part. It can be stabilized. Further, since the joining jig breaks from the slit portion, the breaking position can be set to a desired position, and the intermediate shaft portion of the joining jig can prevent the building member from sliding off.

以下、本発明の実施の形態及び変形例について、図面を用いて詳細に説明する。   Hereinafter, embodiments and modifications of the present invention will be described in detail with reference to the drawings.

〔実施例１〕
本実施例に係る接合構造１を図１〜３を用いて説明する。 [Example 1]
A joining structure 1 according to the present embodiment will be described with reference to FIGS.

図１，２に示すように、接合構造１に用いられる鋼材からなる接合治具５は、円筒状の本体部１９と、転造によって形成されるネジ端部２１と、曲面形状を有する中間軸部２３とを備えている。   As shown in FIGS. 1 and 2, a joining jig 5 made of a steel material used in the joining structure 1 includes a cylindrical main body 19, a screw end 21 formed by rolling, and an intermediate shaft having a curved shape. Part 23.

円筒状の本体部１９は、内周側に中空部２５が形成されており、後述する接着剤１０が充填される。   The cylindrical main body portion 19 has a hollow portion 25 formed on the inner peripheral side, and is filled with an adhesive 10 to be described later.

接合治具５の両端部には、転造によって形成されるネジ端部２１が形成されている。図２（ａ）、（ｂ）に示すように、このネジ端部２１の一方側の第１ネジ端部２１ａには、後述する接着剤１０を充填するためのアダプタを取り付けるためのアダプタ取付部２７が第１ネジ端部２１ａの内周側に形成されている。このアダプタ取付部２７は、第１ネジ端部２１ａの内周側に形成されており、上述した中空部２５と連通している。また、本実施例では第１ネジ端部２１ａにアダプタ取付部２７を形成しているが第２ネジ端部２１ｂに形成してももちろんよい。   Screw ends 21 formed by rolling are formed at both ends of the joining jig 5. As shown in FIGS. 2A and 2B, an adapter mounting portion for mounting an adapter for filling an adhesive 10 to be described later on the first screw end portion 21a on one side of the screw end portion 21. 27 is formed on the inner peripheral side of the first screw end portion 21a. The adapter mounting portion 27 is formed on the inner peripheral side of the first screw end portion 21a and communicates with the hollow portion 25 described above. In this embodiment, the adapter mounting portion 27 is formed on the first screw end portion 21a. However, the adapter mounting portion 27 may be formed on the second screw end portion 21b.

また、本実施例の第１ネジ端部２１ａの長さＬ１と第２ネジ端部２１ｂの長さＬ２は、同じ長さに設定されているが、必ずしも両端のネジ端部の長さが同一でなくてもよい。   In addition, the length L1 of the first screw end portion 21a and the length L2 of the second screw end portion 21b of the present embodiment are set to the same length, but the lengths of the screw end portions at both ends are not necessarily the same. Not necessarily.

第１ネジ端部２１ａと第２ネジ端部２１ｂとの間に狭持されるように配置される中間軸部２３は、外周側が曲面形状を有している。なお、この中間軸部２３は、鋼材からなっており、第１ネジ端部２１ａと第２ネジ端部２１ｂとが離間する方向に伸び変形が可能である。また、この中間軸部２３の第２ネジ端部２１ｂ近傍には、図２（ｃ）に示すようにスリット部２９が凹設して形成されている。   The intermediate shaft portion 23 disposed so as to be sandwiched between the first screw end portion 21a and the second screw end portion 21b has a curved surface shape on the outer peripheral side. The intermediate shaft portion 23 is made of steel, and can be extended and deformed in a direction in which the first screw end portion 21a and the second screw end portion 21b are separated from each other. Further, in the vicinity of the second screw end portion 21b of the intermediate shaft portion 23, a slit portion 29 is formed to be recessed as shown in FIG.

この接合治具５に形成されるスリット部２９の外径は、ネジ端部２１の谷径よりも小さく設定されている。例えば、中間軸部２３の外径が２１．７ｍｍの場合、ネジ端部２１の谷径を２０．７ｍｍとし、スリット部２９の外径が２０．６ｍｍとする。   The outer diameter of the slit portion 29 formed in the joining jig 5 is set smaller than the valley diameter of the screw end portion 21. For example, when the outer diameter of the intermediate shaft portion 23 is 21.7 mm, the valley diameter of the screw end portion 21 is 20.7 mm, and the outer diameter of the slit portion 29 is 20.6 mm.

このように、スリット部２９の外径を接合治具５の他の箇所よりも小径にすることによって、スリット部２９の破壊強度を調整することができるため、スリット部２９から破断を発生させることができる。すなわち、スリット部２９の外径を適宜変更することによって接合治具５の破壊強度を調整することができる。   Thus, since the breaking strength of the slit part 29 can be adjusted by making the outer diameter of the slit part 29 smaller than the other part of the joining jig 5, the fracture from the slit part 29 is generated. Can do. That is, the breaking strength of the joining jig 5 can be adjusted by appropriately changing the outer diameter of the slit portion 29.

図３に示すように、本実施例の建築部材は、２つの建築部材２，３からなっている。   As shown in FIG. 3, the building member of this embodiment is composed of two building members 2 and 3.

第１建築部材２の一面側には、接合治具５の第１ネジ端部２１ａ及び接着剤１０が挿入及び充填される第１治具挿入孔９が形成されている。なお、この第１治具挿入孔９は、上述した接合治具５の第１ネジ端部２１ａの径よりも大きく設定されている。   A first jig insertion hole 9 into which the first screw end 21a of the bonding jig 5 and the adhesive 10 are inserted and filled is formed on one surface side of the first building member 2. The first jig insertion hole 9 is set to be larger than the diameter of the first screw end portion 21a of the joining jig 5 described above.

また、第２建築部材３の一面側においても、接合治具５の第２ネジ端部２１ｂ及び接着剤１０が挿入及び充填される第２治具挿入孔１３が形成されており、第２治具挿入孔１３においても、第２ネジ端部２１ｂの径よりも大きく設定されている。   In addition, on the one surface side of the second building member 3, the second jig end 21 b of the joining jig 5 and the second jig insertion hole 13 into which the adhesive 10 is inserted and filled are formed. The tool insertion hole 13 is also set larger than the diameter of the second screw end 21b.

第１及び第２治具挿入孔９，１３内に充填される接着剤１０は、第１及び第２治具挿入孔９，１３に挿入される接合治具５との隙間を充填するようにして注入される。   The adhesive 10 filled in the first and second jig insertion holes 9 and 13 fills the gap between the bonding jig 5 inserted in the first and second jig insertion holes 9 and 13. Injected.

この接着剤１０は、第１、第２治具挿入孔９，１３へ注入する際には液体であり、液状が第１、第２治具挿入孔９，１３内で硬化して固体状となるものが好ましく、例えば、エポキシ樹脂等が用いられる。   This adhesive 10 is a liquid when injected into the first and second jig insertion holes 9 and 13, and the liquid is cured in the first and second jig insertion holes 9 and 13 to form a solid state. For example, an epoxy resin or the like is used.

なお、本実施例では、第１建築部材２と第２建築部材３とを接合する前に、予め第１治具挿入孔９及び第２治具挿入孔１３に接着剤１０を充填し、接着剤１０を充填した後に接合治具５を第１治具挿入孔９及び第２治具挿入孔１３に挿入し、第１建築部材２と第２建築部材３とを接合する。   In this embodiment, before the first building member 2 and the second building member 3 are joined, the first jig insertion hole 9 and the second jig insertion hole 13 are filled with the adhesive 10 in advance and bonded. After filling the agent 10, the joining jig 5 is inserted into the first jig insertion hole 9 and the second jig insertion hole 13 to join the first building member 2 and the second building member 3.

本実施例では、上述した構成とすることにより、中間軸部２３よりもネジ端部２１の径を大きくすることができ、ネジ端部２１の強度を中間軸部２３の強度よりも強固にすることができる。   In the present embodiment, with the above-described configuration, the diameter of the screw end portion 21 can be made larger than that of the intermediate shaft portion 23, and the strength of the screw end portion 21 is made stronger than the strength of the intermediate shaft portion 23. be able to.

また、ネジ端部２１では、ネジ山の間に接着剤１０が充填されるため、ネジ端部２１と接着剤１０との付着強度を確保することができる。それに対して中間軸部２３では、ネジ山が形成されていないためネジ端部２１よりも接着剤１０の付着強度が低いので、第１建築部材２と第２建築部材３とが離間する方向に過度の力が加わった場合、鋼材の降伏によって中間軸部２３が伸び変形するとともに、中間軸部２３に形成されたスリット部２９にて接合治具５を破断させることができる。すなわち、ネジ端部２１と接着剤１０との付着強度を、中間軸部２３の鋼材の降伏や破壊強度よりも高くすることができるため、ネジ端部２１において破断等が生じることなく、中間軸部２３にて破断を生じさせることができる。   In addition, since the adhesive 10 is filled between the screw threads at the screw end 21, it is possible to ensure the adhesion strength between the screw end 21 and the adhesive 10. On the other hand, in the intermediate shaft portion 23, since no thread is formed, the adhesive strength of the adhesive 10 is lower than that of the screw end portion 21, so that the first building member 2 and the second building member 3 are separated from each other. When an excessive force is applied, the intermediate shaft portion 23 is stretched and deformed by the yield of the steel material, and the joining jig 5 can be broken at the slit portion 29 formed in the intermediate shaft portion 23. That is, since the adhesion strength between the screw end portion 21 and the adhesive 10 can be made higher than the yield or fracture strength of the steel material of the intermediate shaft portion 23, the intermediate shaft without breaking or the like in the screw end portion 21. A break can be caused at the portion 23.

さらに、スリット部２９において接合治具５が破断した場合、中間軸部２３が第１建築部材２と第２建築部材３に形成される第１治具挿入孔９、第２治具挿入孔１３に挿入されているため、接合治具５の破断とともに建築部材の滑落を防止することができる。   Furthermore, when the joining jig 5 is broken at the slit portion 29, the first jig insertion hole 9 and the second jig insertion hole 13 in which the intermediate shaft portion 23 is formed in the first building member 2 and the second building member 3. Therefore, it is possible to prevent the building member from sliding down along with the breakage of the joining jig 5.

加えて、ネジ端部２１を転造ネジによって形成し、スリット部２９を凹設して形成することによって接合治具５を提供することができるので、不要な切削加工を行わないため、製造コストを抑えることができる。   In addition, it is possible to provide the joining jig 5 by forming the screw end portion 21 with a rolled screw and forming the slit portion 29 in a recessed manner. Can be suppressed.

次に、図４〜７を用いて、接合構造１の変形例について説明する。なお、上述した第１実施例と同様の構成については説明を省略する。   Next, the modification of the joining structure 1 is demonstrated using FIGS. The description of the same configuration as that of the first embodiment described above is omitted.

An adhesive injection hole 11 for injecting the adhesive 10 from the other side is formed.

また、第２建築部材３には、第２建築部材３を貫通するようにして第２治具挿入孔１３が設けられている。   Further, the second building member 3 is provided with a second jig insertion hole 13 so as to penetrate the second building member 3.

An adhesive discharge hole 17 through which the adhesive 10 injected from the adhesive injection hole 11 is discharged is formed on the bottom side of the third jig insertion hole 15.

すなわち、第１治具挿入孔９、第３治具挿入孔１５は、第２治具挿入孔１３、を介して連通しており、第１建築部材２の接着剤注入孔１１から注入された接着剤１０が第１治具挿入孔９、第２治具挿入孔１３は、第３治具挿入孔１５、に充填され、第３建築部材４に形成された接着剤排出孔１７から排出される。接着剤１０が接着剤排出孔１７から排出されるのを目視することで接着剤１０の充填が完了する。   That is, the first jig insertion hole 9 and the third jig insertion hole 15 communicate with each other via the second jig insertion hole 13 and are injected from the adhesive injection hole 11 of the first building member 2. The adhesive 10 is filled in the first jig insertion hole 9 and the second jig insertion hole 13 in the third jig insertion hole 15 and discharged from the adhesive discharge hole 17 formed in the third building member 4. The By visually observing that the adhesive 10 is discharged from the adhesive discharge hole 17, the filling of the adhesive 10 is completed.

本変形例によれば、上述した第１実施例と同様の効果を得ることができる。   According to this modification, the same effect as that of the first embodiment described above can be obtained.

また、接着剤１０の充填が完了後、接着剤注入孔１１及び接着剤排出孔１７を木栓等によって塞ぐことにより、美的外観を損ねることなく、第１，２，３建築部材２，３，４の接合を行うことができる。   In addition, after the filling of the adhesive 10 is completed, the adhesive injection hole 11 and the adhesive discharge hole 17 are closed with a wooden plug or the like, so that the aesthetic appearance is not deteriorated. 4 joining can be performed.

〔第２変形例〕
次に、図５を用いて、第２変形例について説明する。 [Second Modification]
Next, a second modification will be described with reference to FIG.

図５に示す本変形例では、第１実施例と同様に建築部材が２つの建築部材２，３からなっている。   In the present modification shown in FIG. 5, the building member is composed of two building members 2 and 3 as in the first embodiment.
