As shown in FIGS. member 5 , bonding material 7 , and filler (for example, adhesive filler) 9 .

ここで、説明の便宜のために、部材の接合構造１における所定の一方向を縦方向とし、縦方向に対して直交する所定の一方向を横方向とし、縦方向と横方向とに対して直交する方向を高さ方向とする。また、図面の寸法比率は説明の都合上誇張されており、実際の比率と異なる場合がある。 Here, for convenience of explanation, the predetermined one direction in the member joining structure 1 is defined as the vertical direction, and the predetermined one direction orthogonal to the vertical direction is defined as the horizontal direction. Let the orthogonal direction be the height direction. Also, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may differ from the actual ratios.

第１の木製の部材３には、孔（止まり孔）１１が設けられている。第２の木製の部材５にも、孔（止まり孔）１３が設けられている。また、第２の木製の部材５は、この孔１３と第１の木製の部材３の孔１１とがお互いにつながるようにして、第１の木製の部材３に接している。 A hole (blind hole) 11 is provided in the first wooden member 3 . A hole (blind hole) 13 is also provided in the second wooden member 5 . The second wooden member 5 is also in contact with the first wooden member 3 such that this hole 13 and the hole 11 of the first wooden member 3 are connected to each other.

接合材７は、第１の木製の部材３の孔１１と第２の木製の部材５の孔１３とに入り込んでいる。充填剤９は、第１の木製の部材３の孔１１と第２の木製の部材５の孔１３とに充填されている。さらに説明すると、充填剤９は、第１の木製の部材３の孔１１の内面と第２の木製の部材５の孔１３の内面と接合材７との間に形成されている間隙４７の総てに充填されている。なお、図３では、孔１１、１３、充填剤９の表示を省略している。 The bonding material 7 enters the hole 11 of the first wooden member 3 and the hole 13 of the second wooden member 5 . The filler 9 fills the holes 11 of the first wooden member 3 and the holes 13 of the second wooden member 5 . More specifically, the filler 9 fills the total gap 47 formed between the inner surface of the hole 11 in the first wooden member 3, the inner surface of the hole 13 in the second wooden member 5, and the joint material 7. filled to the brim. 3, the holes 11 and 13 and the filler 9 are omitted.

接合材７は、図１、図２、図５、１０（ａ）等で示すように、定着部１５と、変形部（靭性担保部）１７とを備えて構成されている。 As shown in FIGS. 1, 2, 5, 10(a), etc., the bonding material 7 includes a fixing portion 15 and a deformation portion (toughness securing portion) 17. As shown in FIG.

定着部１５は、木製の部材３（５）に設けられている孔１１（１３）に挿入されるようになっている。そして、孔１１（１３）に充填され固化した充填剤（たとえば、合成樹脂で構成された接着剤）９を介して定着部１５が木製の部材３（５）に定着され一体的に設置されるようになっている。 The fixing portion 15 is inserted into a hole 11 (13) provided in the wooden member 3 (5). Then, the fixing portion 15 is fixed to the wooden member 3 (5) via a filler (for example, an adhesive made of synthetic resin) 9 that is filled in the hole 11 (13) and solidified, and is integrally installed. It's like

変形部１７は、この長手方向の一端（たとえば一端面もしくは一端面からこの近傍にかけての部位）で、定着部１５の長手方向の一端（たとえば一端面もしくは一端面からこの近傍にかけて部位）を支持している。すなわち、変形部１７は、この長手方向の一端から他端まで所定の長さ延びている。定着部１５は、定着部１５（変形部１７）の長手方向の一端から他端に向けて、変形部１７よりも短い所定の長さ延びている。これにより、接合材７では、この長手方向における定着部１５のところで、定着部１５と変形部１７とが互いがならんで延びている。 The deformation portion 17 supports one longitudinal end of the fixing portion 15 (for example, one end surface or a portion extending from one end surface to the vicinity thereof) at one end in the longitudinal direction (for example, one end surface or a portion extending from the one end surface to the vicinity thereof). ing. That is, the deformation portion 17 extends a predetermined length from one longitudinal end to the other longitudinal end. The fixing portion 15 extends for a predetermined length shorter than the deformation portion 17 from one longitudinal end of the fixing portion 15 (deformation portion 17 ) toward the other end. Thus, in the bonding material 7 , the fixing portion 15 and the deformation portion 17 extend side by side at the fixing portion 15 in the longitudinal direction.

また、変形部１７は、この長手方向の他端部側の部位が定着部１５の長手方向の他端から長く延出（突出）している。変形部１７は、この長手方向での引張荷重（たとえば衝撃引張荷重）がかかったときに、定着部１５と充填剤９との接合部（定着部）にかかる応力を軽減するために設けられている。また、変形部１７は、木製の部材３（５）の孔１１（１３）の内面と充填剤９との接合部（定着部）にかかる応力を軽減するために設けられている。変形部１７は、引張荷重によって一時的に弾性変形することで、上記応力を軽減するようになっている。 In addition, the deformable portion 17 has a portion on the other longitudinal end portion side that protrudes (protrudes) from the other longitudinal end of the fixing portion 15 . The deformation portion 17 is provided to reduce the stress applied to the joining portion (fixing portion) between the fixing portion 15 and the filler 9 when a tensile load (for example, an impact tensile load) is applied in the longitudinal direction. there is The deformation portion 17 is provided to reduce the stress applied to the joint portion (fixing portion) between the inner surface of the hole 11 (13) of the wooden member 3 (5) and the filler 9. The deformable portion 17 is adapted to reduce the stress by temporarily elastically deforming due to the tensile load.

接合材７では、定着部１５の長手方向と変形部１７の長手方向とがお互いに一致している。定着部１５が木製の部材３（５）に充填剤９で固定されている状態で、変形部１７の定着部１５から延出している部位（たとえば、変形部１７の長手方向の他端部）に衝撃引張荷重がかかる。 In the bonding material 7, the longitudinal direction of the fixing portion 15 and the longitudinal direction of the deformation portion 17 are aligned with each other. A portion of the deformation portion 17 extending from the fixing portion 15 (for example, the other longitudinal end portion of the deformation portion 17) while the fixing portion 15 is fixed to the wooden member 3 (5) with the filler 9 is subjected to an impact tensile load.

すると、変形部１７がこの長手方向で一時的に弾性変形するようになっている。この一時的な弾性変形によって、衝撃引張荷重のエネルギーが吸収され、定着部１５と充填剤９との接合部等にかかる応力が軽減されるようになっている。 Then, the deformation portion 17 is temporarily elastically deformed in this longitudinal direction. This temporary elastic deformation absorbs the energy of the impact tensile load and reduces the stress applied to the joint between the fixing portion 15 and the filler 9 and the like.

定着部１５の長手方向の一端が変形部１７の長手方向の一端で支持されていることで、定着部１５と変形部１７とがお互いに一体化している。なお、上記支持がされていることで、接合材７が長手方向の一方の力にのみ抵抗力を有していてもよい。 One longitudinal end of the fixing portion 15 is supported by one longitudinal end of the deforming portion 17, so that the fixing portion 15 and the deforming portion 17 are integrated with each other. Note that the bonding material 7 may have resistance to only one force in the longitudinal direction by being supported as described above.

すなわち、変形部１７を固定しておいて、定着部１５を長手方向の一端側に移動させる力を定着部１５に加えても、定着部１５が変形部１７に対して移動しないようになっている。一方、変形部１７を固定しておいて、定着部１５を長手方向の他端側に移動させる力を定着部１５に加えると、変形部１７に対して定着部１５が移動するようになっていてもよい。 That is, even if the deformation portion 17 is fixed and a force is applied to the fixing portion 15 to move the fixing portion 15 toward one end in the longitudinal direction, the fixing portion 15 does not move with respect to the deformation portion 17 . there is On the other hand, when the deformation portion 17 is fixed and a force is applied to the fixing portion 15 to move the fixing portion 15 to the other end side in the longitudinal direction, the fixing portion 15 moves relative to the deformation portion 17 . may

図４、図１０（ａ）で示すように、接合材７が充填剤９とともに木製の部材３（５）に設置された状態では、定着部１５と変形部１７の一部（少なくとも長手方向で定着部１５と同じところにある部位）とが、木製の部材３（５）の孔１１（１３）に挿入されている。また、変形部１７の長手方向の他端部側の部位が木製の部材３（５）の孔から突出している。充填剤９は、たとえば、木製の部材３（５）の孔１１（１３）の底部から開口部のところまで充填されており孔１１（１３）を埋めている。 As shown in FIGS. 4 and 10(a), when the bonding material 7 is placed on the wooden member 3 (5) together with the filler 9, the fixed portion 15 and part of the deformation portion 17 (at least in the longitudinal direction) are The portion located at the same place as the fixing portion 15) is inserted into the hole 11 (13) of the wooden member 3 (5). A portion of the deformation portion 17 on the other end side in the longitudinal direction protrudes from the hole of the wooden member 3 (5). The filler 9 is, for example, filled from the bottom of the hole 11 (13) of the wooden member 3 (5) to the opening to fill the hole 11 (13).

接合材７が充填剤９とともに木製の部材３（５）に設置され充填剤９が固まり定着部１５が木製の部材３（５）に充填剤９で固定されている。この状態で、接合材７の長手方向の力であって木製の部材３（５）から接合材７を引きぬく方向の小さな力が変形部１７に加わったとする。上記力の値を次第に増やしていく。すると、上記力の値が所定の大きな値になるまでは、変形部１７が伸びる。一方、定着部１５は充填剤９に固着されたままであり、充填剤９は、孔１１（１３）に固着されたままになっている。 The bonding material 7 is placed on the wooden member 3 ( 5 ) together with the filler 9 , and the filler 9 is agglomerated to fix the fixing portion 15 to the wooden member 3 ( 5 ) with the filler 9 . In this state, it is assumed that a force in the longitudinal direction of the joint material 7 and a small force in the direction of pulling out the joint material 7 from the wooden member 3 ( 5 ) is applied to the deformation portion 17 . Gradually increase the force value. Then, the deformation portion 17 extends until the value of the force reaches a predetermined large value. On the other hand, the fixing portion 15 remains adhered to the filler 9, and the filler 9 remains adhered to the hole 11 (13).

ここで、変形部１７と定着部１５の長手方向での変形部１７と定着部１５との支持位置についてさらに説明する。上述した説明では、変形部１７の長手方向の一端で定着部１５の長手方向の一端を支持しているが、一端に限定することなく一端を一端部にしてもよい。ここで、一端部とは、一端よりも僅かに広い範囲を示しており、一端から他端側に僅かに離れた箇所との間の部位である。 Here, the supporting positions of the deforming portion 17 and the fixing portion 15 in the longitudinal direction of the deforming portion 17 and the fixing portion 15 will be further described. In the above description, one longitudinal end of the deforming portion 17 supports one longitudinal end of the fixing portion 15 , but the one end may be one end. Here, the one end indicates a slightly wider range than the one end, and is a portion between the one end and a point slightly away from the other end.

さらに、変形部１７の長手方向の一端部で定着部１５の長手方向の中間部を支持してもよいし、変形部１７の長手方向の中間部で定着部１５の長手方向の一端部を支持してもよいし、変形部１７の長手方向の中間部で定着部１５の長手方向の中間部を支持してもよい。この場合、上記中間部は長手方向での中間よりも一端側に位置していることが望ましい。 Further, one longitudinal end portion of the deformation portion 17 may support the longitudinal intermediate portion of the fixing portion 15 , and the longitudinal intermediate portion of the deformation portion 17 may support one longitudinal end portion of the fixing portion 15 . Alternatively, the longitudinal intermediate portion of the deformation portion 17 may support the longitudinal intermediate portion of the fixing portion 15 . In this case, it is desirable that the intermediate portion is positioned closer to one end than the intermediate portion in the longitudinal direction.

ここで、接合材７について図１、図２、図５を参照しつつさらに具体的に説明する。 Here, the bonding material 7 will be described in more detail with reference to FIGS. 1, 2 and 5. FIG.

接合材７は、変形部１７を構成している棒状の芯材１９と、中間材２１と、定着部１５を構成している第１の定着部材２３と、変形部１７で定着部１５を支持するための第１の端部材２５とを備えて構成されている。 The bonding material 7 supports the fixing portion 15 with the rod-shaped core material 19 forming the deformation portion 17 , the intermediate member 21 , the first fixing member 23 forming the fixing portion 15 , and the deformation portion 17 . and a first end member 25 for

芯材１９は、たとえば、背の高い円柱状に形成されている。円柱状ということなので、棒状の芯材１９は、完全な円柱形状ではなく円柱に近似した形状になっている。たとえば、芯材１９の長手方向の端部には所定の長さにわたってオスネジ２７が形成されている。これにより、芯材１９が細長い円柱状に形成されていることになる。オスネジ２７は、たとえば、円柱の材料を転造することによって形成されている。転造によって形成された場合には、オスネジ２７の山径の値は、オスネジ２７が形成されていない芯材１９の長手方向の中間部の外径の値とよりも僅かに大きくなっている。なお、オスネジ２７が、切削加工によって形成されていてもよい。切削加工によって形成されている場合には、芯材１９のオスネジ２７の山径の値は、オスネジ２７が形成されていない芯材１９の長手方向の中間部の外径の値とほぼ等しくなっている。なお、芯材１９の長手方向は、たとえば、図３、図４等で示す縦方向と一致している。 Core material 19 is formed in a tall columnar shape, for example. Since it is columnar, the rod-shaped core material 19 does not have a perfect columnar shape, but has a shape similar to a columnar column. For example, a male screw 27 is formed over a predetermined length at the longitudinal end of the core member 19 . As a result, the core material 19 is formed in an elongated cylindrical shape. The male screw 27 is formed, for example, by rolling a cylindrical material. When formed by rolling, the thread diameter of the male thread 27 is slightly larger than the outer diameter of the central portion in the longitudinal direction of the core member 19 where the male thread 27 is not formed. In addition, the male screw 27 may be formed by cutting. When formed by cutting, the value of the ridge diameter of the male thread 27 of the core material 19 is substantially equal to the value of the outer diameter of the intermediate portion in the longitudinal direction of the core material 19 where the male thread 27 is not formed. there is Note that the longitudinal direction of the core material 19 coincides with the vertical direction shown in FIGS. 3 and 4, for example.

中間材２１は、筒状に形成されており、芯材１９が貫通するようにして芯材１９の長手方向の中間部に設置されている。中間材２１は、たとえば、完全な円筒形状になっている。中間材２１の内径の値は、芯材１９の外径の値よりも僅かに大きくなっている。中間材２１の長さ寸法の値（中心軸の延伸方向における寸法の値）は、芯材１９の長さ寸法の値（中心軸の延伸方向における寸法の値）よりも小さくなっている。 The intermediate member 21 is formed in a cylindrical shape, and is installed in a longitudinally intermediate portion of the core member 19 so that the core member 19 penetrates through the intermediate member 21 . The intermediate member 21 has, for example, a perfect cylindrical shape. The value of the inner diameter of the intermediate member 21 is slightly larger than the value of the outer diameter of the core member 19 . The value of the length dimension of the intermediate member 21 (the value of the dimension in the extending direction of the central axis) is smaller than the value of the length dimension of the core member 19 (the value of the dimension in the extending direction of the central axis).

第１の定着部材２３は、筒状に形成されており、外周面に凹凸が形成されており、芯材１９が貫通し中間材２１に接するか中間材２１から僅かに離れるようにして、芯材１９の長手方向の一方の端側（第１の端側）に設置されている。第１の定着部材２３の凹凸は、第１の定着部材２３と充填剤９との接合強度を高めるために設けられている。 The first fixing member 23 is formed in a cylindrical shape, and unevenness is formed on the outer peripheral surface. It is installed on one end side (first end side) of the material 19 in the longitudinal direction. The unevenness of the first fixing member 23 is provided to increase the bonding strength between the first fixing member 23 and the filler 9 .

第１の定着部材２３は、外周面に凹凸が形成されていないとすれば、完全な円筒形状になっている。第１の定着部材２３の内径の値は、芯材１９の外径の値よりも僅かに大きくなっている。第１の定着部材２３の長さ寸法の値（中心軸の延伸方向における寸法の値）は、芯材１９の長さ寸法の値（中心軸の延伸方向における寸法の値）よりも小さくなっている。 The first fixing member 23 has a completely cylindrical shape, provided that no unevenness is formed on the outer peripheral surface. The inner diameter of the first fixing member 23 is slightly larger than the outer diameter of the core member 19 . The value of the length dimension of the first fixing member 23 (the value of the dimension in the extending direction of the central axis) is smaller than the value of the length dimension of the core member 19 (the value of the dimension in the extending direction of the central axis). there is

第１の定着部材２３の外周面の最大外径の値は、中間材２１の外径の値とほぼ等しくなっている。第１の定着部材２３の外周面の凹凸は、たとえば、オスネジ２９で形成されている。オスネジ２９は、たとえば、中間材２１と同様な材料を転造することによって形成されている。転造することによって形成されている場合には、第１の定着部材２３のオスネジ２９の山径の値は、中間材２１の外径の値よりも僅かに大きくなっている。なお、オスネジ２９は、たとえば、中間材２１と同様な材料に切削加工を施すことで形成されていてもよい。切削加工で形成されている場合には、オスネジ２９の山径の値が、中間材２１の外径の値とほぼ等しくなっている。 The maximum outer diameter value of the outer peripheral surface of the first fixing member 23 is substantially equal to the outer diameter value of the intermediate member 21 . The irregularities on the outer peripheral surface of the first fixing member 23 are formed by, for example, male screws 29 . The male screw 29 is formed by rolling a material similar to the intermediate material 21, for example. When formed by rolling, the thread diameter of the male screw 29 of the first fixing member 23 is slightly larger than the outer diameter of the intermediate member 21 . The male screw 29 may be formed by cutting a material similar to that of the intermediate member 21, for example. When formed by cutting, the thread diameter of the male screw 29 is substantially equal to the outer diameter of the intermediate member 21 .

第１の端部材２５は、芯材１９の長手方向の一方の端側（第１の端側）あって第１の定着部材２３よりもさらなる端側で、第１の定着部材２３に接するか第１の定着部材２３から僅かに離れるようにして、芯材１９に一体的に設置されている。 The first end member 25 contacts the first fixing member 23 on one end side (first end side) in the longitudinal direction of the core material 19 and further on the end side than the first fixing member 23 . It is installed integrally with the core member 19 so as to be slightly separated from the first fixing member 23 .

第１の端部材２５はたとえばナットで構成されている。ナット２５は、棒状の芯材１９の長手方向の一方の端部に形成されているオスネジ２９に螺合している。ナット２５の最大外径の値は、たとえば、中間材２１の外径の値とほぼ等しくなっている。 The first end member 25 consists of a nut, for example. The nut 25 is screwed onto a male thread 29 formed at one longitudinal end of the rod-shaped core member 19 . The maximum outer diameter of nut 25 is, for example, approximately equal to the outer diameter of intermediate member 21 .

芯材１９に中間材２１と第１の定着部材２３と第１の端部材２５とが設置されていることで、接合材７が形成されている。そして、接合材７の外形が概ね棒状（たとえば円柱状）に形成されている。なお、芯材１９の長手方向の一方の端部は、第１の端部材２５から僅かに突出している。また、詳しくは後述する第２の定着部材３１と第２の端部材３３とが設けられていないとすれば、芯材１９の長手方向の他方の端部は、中間材２１から所定の長さ突出している。 The bonding material 7 is formed by installing the intermediate member 21 , the first fixing member 23 and the first end member 25 on the core member 19 . The outer shape of the bonding material 7 is generally rod-shaped (for example, cylindrical). One longitudinal end of the core member 19 protrudes slightly from the first end member 25 . Further, if a second fixing member 31 and a second end member 33, which will be described later in detail, are not provided, the other end in the longitudinal direction of the core member 19 is a predetermined length from the intermediate member 21. Protruding.

接合材７では、第１の端部材２５が設けられていることで、第１の定着部材２３と中間材２１とが、芯材１９に対して芯材１９の長手方向の一方の端側に移動して芯材１９から外れ落ちてしまうことが防止されるようになっている。 In the bonding material 7 , the first end member 25 is provided, so that the first fixing member 23 and the intermediate material 21 are arranged on one end side of the core material 19 in the longitudinal direction. It is prevented from moving and falling off the core material 19. - 特許庁

また、接合材７には、定着部１５を構成している第２の定着部材３１と、変形部１７が定着部１５を支持するための第２の端部材３３とを備えて構成されている。第２の定着部材３１は、たとえば、第１の定着部材２３と同形状に形成されている。すなわち、第２の定着部材３１は、筒状に形成されており、外周面に凹凸が形成されている。また、第２の定着部材３１は、芯材１９が貫通し、中間材２１に接するか中間材２１から僅かに離れるようにして、芯材１９の長手方向の他方の端側（第２の端側）に設置されている。 The bonding material 7 includes a second fixing member 31 forming the fixing portion 15 and a second end member 33 for supporting the fixing portion 15 by the deformation portion 17 . . The second fixing member 31 is formed in the same shape as the first fixing member 23, for example. That is, the second fixing member 31 is formed in a cylindrical shape, and unevenness is formed on the outer peripheral surface. In addition, the second fixing member 31 has the core material 19 penetrating therethrough, and is in contact with the intermediate material 21 or is slightly separated from the intermediate material 21 so that the other end side (second end) in the longitudinal direction of the core material 19 is arranged. side).

第２の端部材３３は、芯材１９の長手方向の他方の端側（第２の端側）あって第２の定着部材３１よりもさらなる端側で、第２の定着部材３１に接するか第２の定着部材３１から僅かに離れるようにして、芯材１９に設置されている。 The second end member 33 contacts the second fixing member 31 on the other end side (second end side) in the longitudinal direction of the core material 19 and further on the end side than the second fixing member 31 . It is installed on the core material 19 so as to be slightly separated from the second fixing member 31 .

第２の端部材３３も、第１の端部材２５と同様に、たとえばナットで構成されている。ナット３３は、棒状の芯材１９の長手方向の他方の端部に形成されているオスネジ３５に螺合している。 Like the first end member 25, the second end member 33 also consists of a nut, for example. The nut 33 is screwed onto a male screw 35 formed at the other end in the longitudinal direction of the rod-shaped core member 19 .

芯材１９に中間材２１と第１の定着部材２３と第２の定着部材３１と第１の端部材２５と第２の端部材３３とが設置されていることでも、接合材７が形成されている。そして、接合材７の外形が棒状（たとえば円柱状）に形成されている。 The bonding material 7 is also formed by placing the intermediate member 21 , the first fixing member 23 , the second fixing member 31 , the first end member 25 , and the second end member 33 on the core member 19 . ing. The outer shape of the bonding material 7 is formed in a bar shape (for example, a cylindrical shape).

第２の定着部材３１と第２の端部材３３とが設けられている接合材７では、芯材１９の長手方向の一方の端から他方の端に向かうにしたがって、第１の部材２５、第１の定着部材２３、中間材２１、第２の定着部材３１、第２の端部材３３とがこの順にならんでいる。また、第２の定着部材３１等が設けられている接合材７では、芯材１９の長手方向の一端部が第１の端部材２５から僅かに突出しており、芯材１９の長手方向の他端部が第２の端部材３３から僅かに突出している。 In the bonding material 7 in which the second fixing member 31 and the second end member 33 are provided, the first member 25 and the second end member 19 move from one longitudinal end to the other longitudinal end of the core member 19 . One fixing member 23, intermediate member 21, second fixing member 31, and second end member 33 are arranged in this order.

Disengagement from the material 19 is prevented. However, the first fixing member 23, the intermediate member 21, and the second fixing member 31 are not tightened by the first end member 25 and the second end member 33 in the longitudinal direction of the core member 19. . Note that the first fixing member 23, the intermediate member 21, and the second fixing member 31 are tightened with a biasing force in the longitudinal direction of the core member 19 by the first end member 25 and the second end member 33. may have been

The intermediate member 21, the first fixing member 23, the second fixing member 31, the first end member 25, and the second end member 33 are also made of metal such as steel. Note that the intermediate member 21, the first fixing member 23, and the second fixing member 31 may be made of a nonmetallic material such as hard synthetic resin or ceramics.

また、芯材１９と、中間材２１および第１の定着部材２３および第２の定着部材３１との間の僅かな間隙３７が、合成樹脂等の充填剤９で充填されていてもよいし、充填剤で充填されておらず空洞状態になっていてもよい。間隙３７は、接合材７の径方向における円筒状の間隙である。充填剤９は、木製の部材３（５）の孔１１（１３）に充填されている充填剤と同じ充填剤になっている。なお、充填剤９が、木製の部材３（５）の孔１１（１３）に充填されている充填剤と異なる仕様の充填剤になっていてもよい。 Further, a slight gap 37 between the core material 19 and the intermediate material 21 and the first fixing member 23 and the second fixing member 31 may be filled with a filler 9 such as a synthetic resin. It may be in a hollow state without being filled with a filler. The gap 37 is a cylindrical gap in the radial direction of the bonding material 7 . The filler 9 is the same filler that fills the holes 11 (13) of the wooden member 3 (5). In addition, the filler 9 may be a filler with specifications different from the filler filled in the hole 11 (13) of the wooden member 3 (5).

なお、上記説明では、定着部材２３（３１）は、外周にオスネジ２７が形成されている円筒状になっているが、外周に他の態様で凹凸が形成されているもよい。たとえば、図６（ａ）で示すように、大径部３９と小径部４１とが、筒の中心軸の延伸方向で、交互にならんでいる態様であってもよい。 In the above description, the fixing member 23 (31) has a cylindrical shape with the male screw 27 formed on the outer circumference, but the outer circumference may be uneven in another manner. For example, as shown in FIG. 6A, large-diameter portions 39 and small-diameter portions 41 may be arranged alternately in the extending direction of the central axis of the cylinder.

図６（ａ）で示す定着部材２３（３１）では、外周の断面形状が三角波の形状になっているが、外周の断面形状が矩形波の形状になっていてもよいし、等脚台形波等の台形波の形状になっていてもよい。さらに、外周の断面形状が正弦波等の他の形状になっていてもよいし、不規則な形態で定着部材２３（３１）の外周に凹凸が形成されていてもよい。 In the fixing member 23 (31) shown in FIG. 6A, the cross-sectional shape of the outer periphery is triangular wave, but the cross-sectional shape of the outer periphery may be rectangular wave or isosceles trapezoidal wave. It may be in the shape of a trapezoidal wave such as . Furthermore, the cross-sectional shape of the outer periphery may be another shape such as a sinusoidal wave, or unevenness may be formed on the outer periphery of the fixing member 23 (31) in an irregular form.

This makes it possible to easily adjust the value of the length dimension of the fixing member 23 (31) (the dimension in the extension direction of the central axis of the cylinder), and to increase the value of the length dimension of the fixing member 23 (31). Even then, a through hole for forming a cylinder can be easily provided by machining.

各部材２３Ａ、２３Ｂ、２３Ｃ、２３Ｄ（３１Ａ、３１Ｂ、３１Ｃ、３１Ｄ）の寸法（筒の中心軸の延伸方向における寸法）の値は、たとえば、お互い異なっている。なお、各部材２３Ａ、２３Ｂ、２３Ｃ、２３Ｄ（３１Ａ、３１Ｂ、３１Ｃ、３１Ｄ）のうちの少なくとも一部のもので、寸法（筒の中心軸の延伸方向における寸法）の値がお互いに一致していてもよい。 The values of the dimensions (dimensions in the extending direction of the central axis of the cylinder) of the respective members 23A, 23B, 23C, 23D (31A, 31B, 31C, 31D) are different from each other, for example. At least some of the members 23A, 23B, 23C, and 23D (31A, 31B, 31C, and 31D) have the same dimension (dimension in the extending direction of the central axis of the cylinder). may

図６（ｃ）で示す定着部材２３（３１）は、金属製のフレキシブルチューブを所定の長さに切断したことで形成されている。図６（ｃ）で示す定着部材２３（３１）では、筒の外周だけでなく、筒の内周にも繰り返し凹凸が形成されている。 The fixing member 23 (31) shown in FIG. 6C is formed by cutting a metal flexible tube into a predetermined length. In the fixing member 23 (31) shown in FIG. 6C, not only the outer circumference of the cylinder but also the inner circumference of the cylinder are repeatedly formed with unevenness.

また、定着部材２３（３１）を、鉄筋コンクリートに使用される異形鉄筋を素材として形成してもよい。すなわち、異形鉄筋を所定の長さに切断し、この切断した異形鉄筋に貫通孔を設けて筒状に形成し、これを定着部材２３（３１）として採用してもよい。 Further, the fixing member 23 (31) may be formed using a deformed reinforcing bar used for reinforced concrete as a material. That is, a deformed reinforcing bar may be cut into a predetermined length, a through hole may be provided in the cut deformed reinforcing bar, and the cut deformed reinforcing bar may be formed into a cylindrical shape, which may be employed as the fixing member 23 (31).

The hole 13 of the second wooden member 5 is recessed from one end face of the second wooden member 5 in the longitudinal direction to the other end face facing this one end face.

第１の木製の部材３の孔１１と第２の木製の部材５の孔１３とは、上述したようにお互いがつながっているとともに、これらの中心軸がお互いに一致している。これにより、１つの孔１１と１つの孔１３とで、１つの円柱状の閉鎖された空間４３が形成されている。 The hole 11 of the first wooden member 3 and the hole 13 of the second wooden member 5 are connected to each other as described above, and their central axes are aligned with each other. Thus, one hole 11 and one hole 13 form one cylindrical closed space 43 .

なお、上記説明では、第１の木製の部材３の孔１１（第２の木製の部材５の孔１３）が円柱状に形成されていることになる。ここで、第１の木製の部材３の孔１１（第２の木製の部材５の孔１３）をメスネジで形成する等し、第１の木製の部材３の孔１１（第２の木製の部材５の孔１３）の側面に凹凸が繰り返し現れる形態にしてもよい。 In the above description, the hole 11 of the first wooden member 3 (the hole 13 of the second wooden member 5) is formed in a cylindrical shape. Here, the hole 11 of the first wooden member 3 (the hole 13 of the second wooden member 5) is formed with a female screw or the like, and the hole 11 of the first wooden member 3 (the hole 13 of the second wooden member 5, the hole 13) may have a form in which unevenness appears repeatedly.

円柱形状の空間４３の長手方向（円柱の高さ方向）は縦方向になっている。なお、空間４３は、詳しくは後述する充填剤の導入孔４５が形成されているので、厳密には閉鎖されていないが、ここでは、閉鎖された空間とする。閉鎖された空間４３は、複数（たとえば２つ）設けられている。複数の空間４３は、お互いが所定の距離だけ離れて配置されている。 The longitudinal direction (the height direction of the cylinder) of the cylindrical space 43 is the vertical direction. Strictly speaking, the space 43 is not closed because the space 43 is formed with an introduction hole 45 for a filler, which will be described later in detail. A plurality of (for example, two) closed spaces 43 are provided. A plurality of spaces 43 are arranged at predetermined distances from each other.

空間４３の円柱の径は、接合材７の外径よりもわずかに大きくなっており、空間４３の円柱の高さ寸法の値は、接合材７の高さ寸法の値よりもわずかに大きくなっている。そして、空間４３に接合材７が配置されていることで、空間４３の内壁面と接合材７との間には、間隙４７が形成されている。充填剤９は、間隙４７の総てにわたって充填されている。 The diameter of the cylinder in the space 43 is slightly larger than the outer diameter of the bonding material 7 , and the height dimension of the cylinder in the space 43 is slightly larger than the height dimension of the bonding material 7 . ing. Since the bonding material 7 is arranged in the space 43 , a gap 47 is formed between the inner wall surface of the space 43 and the bonding material 7 . The filler 9 fills the entire gap 47 .

空間４３に接合材７が配置されている状態では、接合材７の中間材２１の長手方向の一方の部位と第１の定着部材２３と第１の端部材２５とが第１の木製の部材３の孔１１に入り込んでいる。また、空間４３に接合材７が配置されている状態では、接合材７の中間材２１の長手方向の他方の部位と第２の定着部材３１と第２の端部材３３とが第２の木製の部材５の孔１３に入り込んでいる。 In the state where the bonding material 7 is arranged in the space 43, one portion of the intermediate member 21 of the bonding material 7 in the longitudinal direction, the first fixing member 23, and the first end member 25 are the first wooden members. 3 enters the hole 11.

A small hole 45 connects the outside of the first wooden member 3 and the second wooden member 5 with the space 43 . A small hole 45 in the first wooden member 3 connects to the space 43 at one longitudinal end of the space 43 . A small hole 45 in the second wooden member 5 connects to the space 43 at the other longitudinal end of the space 43 .

小孔４５は、充填剤９を空間４３内に充填するために使用される他、充填剤９を充填しているときに空間４３内の空気を排出するためのエアー抜き孔としても使用されるようになっている。 The small hole 45 is used to fill the space 43 with the filler 9, and is also used as an air vent hole for discharging the air in the space 43 while filling the filler 9. It's like

なお、図４で示す部材の接合構造１では、空間４３の総てが充填剤９で満たされているが、中間材２１のところに、充填剤９が存在しておらず空隙になっていてもよい。すなわち、中間材２１の外周面が充填剤９と接触していない構成であってもよい。 In addition, in the joint structure 1 of members shown in FIG. 4, the entire space 43 is filled with the filler 9, but the filler 9 does not exist at the intermediate member 21, leaving a gap. good too. That is, a configuration in which the outer peripheral surface of the intermediate member 21 is not in contact with the filler 9 may be employed.

ここで、部材の接合構造１での組立手順について説明する。 Here, the procedure for assembling the member joining structure 1 will be described.

第１の木製の部材３の孔１１に接合材７の一方の端部を挿入して状態で、第２の木製の部材５の孔１３に接合材７の他方の端部が入るようにして、第１の木製の部材３に第２の木製の部材５を設置する。これにより、接合材７が入っている空間４３が形成される。 With one end of the joint material 7 inserted into the hole 11 of the first wooden member 3, the other end of the joint material 7 is inserted into the hole 13 of the second wooden member 5. , placing a second wooden member 5 on the first wooden member 3 . Thereby, a space 43 containing the bonding material 7 is formed.

続いて、小孔４５を用いて空間４３内に流動体状の充填剤９を充填し、この後、充填剤９を硬化させることで、部材の接合構造１が得られる。 Subsequently, the spaces 43 are filled with the fluid filler 9 using the small holes 45, and then the filler 9 is cured to obtain the joining structure 1 of the members.

次に、部材の接合構造１に荷重が加えられた場合について説明する。 Next, a case where a load is applied to the joining structure 1 of members will be described.

第１の木製の部材３を固定しておき、図４に矢印Ａ１で示す衝撃力（引張衝撃荷重）を第２の木製の部材５に加える。すると、充填剤９と第１の木製の部材３の孔１１の内面との接合部、充填剤９と第２の木製の部材５の孔１３の内面との接合部に、応力が発生する。また、充填剤９と第１の定着部材２３との接合部、充填剤９と第２の定着部材３１との接合部、および、芯材１９に応力が発生する。 The first wooden member 3 is fixed, and an impact force (tensile impact load) indicated by arrow A1 in FIG. 4 is applied to the second wooden member 5 . Then, stress is generated at the joint between the filler 9 and the inner surface of the hole 11 of the first wooden member 3 and the joint between the filler 9 and the inner surface of the hole 13 of the second wooden member 5 . Moreover, stress is generated in the joint portion between the filler 9 and the first fixing member 23 , the joint portion between the filler 9 and the second fixing member 31 , and the core material 19 .

上記衝撃力によって、芯材１９に発生する引張応力によって芯材１９が、縦方向にたとえば弾性限度内で一時的に延び、または、塑性変形により延び、上記衝撃力のエネルギーを吸収する。これにより、充填剤９と孔１１の内面との接合部、充填剤９と孔１３の内面との接合部、充填剤９と第１の定着部材２３との接合部、充填剤９と第２の定着部材３１との接合部における充填剤９の剥離、損傷等が防止される。 Due to the impact force, the tensile stress generated in the core member 19 causes the core member 19 to temporarily extend in the longitudinal direction, for example, within the elastic limit, or to extend due to plastic deformation, thereby absorbing the energy of the impact force. As a result, the joint portion between the filler 9 and the inner surface of the hole 11, the joint portion between the filler 9 and the inner surface of the hole 13, the joint portion between the filler 9 and the first fixing member 23, the filler 9 and the second fixing member 23 are formed. Peeling, damage, etc. of the filler 9 at the joint portion with the fixing member 31 are prevented.

また、図５で示す間隙３７に充填剤９が充填されている態様で第１の木製の部材３を固定しておき、図４に矢印Ａ１で示す衝撃力（引張衝撃荷重）を第２の木製の部材５に加える。すると、芯材１９と充填剤９との接合部で芯材１９から充填剤９が先に剥離し、芯材１９が縦方向にたとえば弾性限度内で一時的に延び、または、塑性変形により延びる。そして、上記衝撃力のエネルギーを吸収する。 Also, the first wooden member 3 is fixed in such a manner that the filler 9 is filled in the gap 37 shown in FIG. Add to wooden member 5. Then, the filler 9 is first peeled off from the core material 19 at the junction between the core material 19 and the filler 9, and the core material 19 extends in the vertical direction temporarily within the elastic limit or due to plastic deformation. . Then, the energy of the impact force is absorbed.

なお、芯材１９と充填剤９との接合部で芯材１９から充填剤９が先に剥離する理由は、芯材１９の外径が小さく芯材１９と充填剤９との接合部（円柱側面状の接合部）の面積が小さくなっているからである。また、芯材１９と充填剤９との接合部で芯材１９から充填剤９が先に剥離する理由は、芯材１９がこの長手方向で僅かに延びることにより、ポアソン比に応じて、芯材１９の外径が僅かに小さくなるからである。 The reason why the filler 9 peels off first from the core material 19 at the joint portion between the core material 19 and the filler 9 is that the outer diameter of the core material 19 is small and the joint portion (columnar column) between the core material 19 and the filler 9 This is because the area of the lateral joint) is small. In addition, the reason why the filler 9 peels off first from the core material 19 at the joint portion between the core material 19 and the filler 9 is that the core material 19 slightly extends in the longitudinal direction, so that the core This is because the outer diameter of the material 19 is slightly reduced.

なお、図４に矢印Ａ１で示す引張衝撃荷重に代えてもしくは加えて、図４に矢印Ａ２で示すモーメント（衝撃荷重に相当するモーメント）を第２の木製の部材５に加える。これによっても、矢印Ａ１で示す引張衝撃荷重の場合と同様にして、上述した充填剤９の剥離、損傷等が防止される。 In place of or in addition to the tensile impact load indicated by arrow A1 in FIG. 4, a moment (moment corresponding to the impact load) indicated by arrow A2 in FIG. This also prevents the filler 9 from being peeled off, damaged, etc., as in the case of the tensile impact load indicated by the arrow A1.

部材の接合構造１では、定着部１５が木製の部材３（５）に設けられている孔１１（１３）に挿入され充填剤９を介して木製の部材３（５）に定着されるように構成されており、変形部１７が長手方向の一端で定着部１５の長手方向の一端を支持している。また、変形部１７の長手方向の他端部側の部位が定着部１５の長手方向の他端から延出している。 In the member joining structure 1, the fixing portion 15 is inserted into the hole 11 (13) provided in the wooden member 3 (5) and fixed to the wooden member 3 (5) via the filler 9. The deformation portion 17 supports one end of the fixing portion 15 in the longitudinal direction at one end in the longitudinal direction. Further, a portion of the deformation portion 17 on the side of the other end in the longitudinal direction extends from the other end of the fixing portion 15 in the longitudinal direction.

そして、変形部１７にこの長手方向の引張荷重（たとえば衝撃引張荷重）がかかったときの、定着部１５と充填剤９との接合部等にかかる応力を軽減するために、上記引張荷重によって変形部１７が一時的に弾性変形し、または、塑性変形する。 Then, in order to reduce the stress applied to the joint portion between the fixing portion 15 and the filler 9 when the deformation portion 17 is subjected to a tensile load (for example, an impact tensile load) in the longitudinal direction, deformation due to the tensile load is performed. The portion 17 is temporarily elastically deformed or plastically deformed.

これにより、木製の部材３（５）に衝撃力等の力が加わった場合であっても充填剤９と接合材７との接合部、充填剤９と木製の部材３（５）との接合部に係る応力が低減され、充填剤９の剥離等が極力防止される。 As a result, even when a force such as an impact force is applied to the wooden member 3 (5), the joint between the filler 9 and the jointing material 7 and the joint between the filler 9 and the wooden member 3 (5) The stress on the part is reduced, and peeling of the filler 9 is prevented as much as possible.

さらに、接合材７では、変形部１７の長手方向の端部だけで定着部１５の長手方向の端部だけを支持している。これにより、変形部１７の長手方向の一部で、定着部１５をこの長手方向の全長にわたって支持する場合に比べて、変形部１７において弾性変形する部位の長さを長くすることができ、接合材７を次に述べる比較例に係るものより短くしても衝撃力を十分に吸収することができる。 Furthermore, in the bonding material 7 , only the longitudinal ends of the deformation portions 17 support only the longitudinal ends of the fixing portions 15 . As a result, compared to the case where the fixing portion 15 is supported over the entire longitudinal length of the deformable portion 17 by a portion of the deformable portion 17, the length of the elastically deformable portion of the deformable portion 17 can be increased. Even if the material 7 is made shorter than that according to the comparative example described below, the impact force can be sufficiently absorbed.

ここで、比較例に係る部材の接合構造３０１について、図１３を参照しつつ説明する。 Here, a member joining structure 301 according to a comparative example will be described with reference to FIG. 13 .

接合構造３０１では、孔３０７が設けられている一方の木製の部材３０９と、同様にして孔３１１が設けられている他方の木製の部材３１３とを、孔３０７と孔３１１とが通じるようにして、木製の部材３０９端面と木製の部材３１３の端面とを合わせている。 In the joint structure 301, one wooden member 309 provided with a hole 307 and the other wooden member 313 similarly provided with a hole 311 are connected so that the hole 307 and the hole 311 communicate with each other. , the end face of the wooden member 309 and the end face of the wooden member 313 are aligned.

また、接合構造３０１では、オスネジ材３０３の長手方向の一方の端部が一方の木製の部材３０９の孔３０７に入っており、オスネジ材３０３の長手方向の他方の端部が他方の木製の部材３１３の孔３１１に入っている。 In addition, in the joint structure 301, one longitudinal end of the male screw member 303 is inserted into the hole 307 of one wooden member 309, and the other longitudinal end of the male screw member 303 is inserted into the other wooden member. It enters the hole 311 of 313 .

さらに、接合構造３０１では、孔３０７、３１１とオスネジ材３０３との間に接着剤３０５を充填している。これにより、一方の木製の部材３０９と他方の木製の部材３１３との接合強度を高めている。たとえば、図１３に矢印で示す力（ある程度の大きさの力）が、木製の部材３０９、３１３にかかっても、一方の木製の部材３０９と他方の木製の部材３１３との接合が維持されるようになっている。 Furthermore, in the joint structure 301 , an adhesive 305 is filled between the holes 307 and 311 and the male screw material 303 . This increases the joint strength between the wooden member 309 on one side and the wooden member 313 on the other side. For example, even if a force indicated by an arrow in FIG. 13 (force of a certain magnitude) is applied to the wooden members 309 and 313, the joint between one wooden member 309 and the other wooden member 313 is maintained. It's like

ところで、従来の接合構造３０１において、図１３に矢印で示す力（たとえば衝撃力）がかかったときに、オスネジ材３０３と接着剤３０５との接合部での接着剤（充填剤）３０５の剥離等が発生する事態の発生が懸念される。また、接着剤３０５と木製の部材３０９、３１３との接合部での接着剤（充填剤）３０５の剥離等が発生する事態の発生が懸念される。この理由は、衝撃力に対するオスネジ材３０３の伸び量が不十分で衝撃力のエネルギーを十分に吸収することができないからである。衝撃力のエネルギーを十分に吸収させるためには、オスネジ材３０３の長さ寸法の値をさらに大きくする等の形状変更が必要になる。 By the way, in the conventional joint structure 301, when a force (for example, an impact force) indicated by an arrow in FIG. There is concern about the occurrence of a situation where In addition, there is concern that the adhesive (filler) 305 may peel off at the joints between the adhesive 305 and the wooden members 309 and 313 . The reason for this is that the amount of elongation of the male screw member 303 against the impact force is insufficient and the energy of the impact force cannot be sufficiently absorbed. In order to sufficiently absorb the energy of the impact force, it is necessary to change the shape of the male screw member 303, such as further increasing the value of the length dimension.

また、部材の接合構造１で使用される接合材７が、棒状の芯材１９と、筒状に形成され芯材１９が貫通するようにして芯材１９の長手方向の中間部に設置される中間材２１とを備えて構成されている。また、接合材７が、第１の定着部材２３と第１の端部材２５とを備えて構成されている。 Also, the joining material 7 used in the joining structure 1 of the members is formed in a rod-like core material 19 and is formed in a cylindrical shape, and is installed in the middle part of the core material 19 in the longitudinal direction so that the core material 19 penetrates. An intermediate member 21 is provided. Also, the bonding material 7 includes a first fixing member 23 and a first end member 25 .

ここで、第１の定着部材２３が筒状に形成されており外周面に凹凸が形成されており芯材１９が貫通し中間材２１に接するようにして芯材１９の長手方向の一方の端側（第１の端側）に設置されている。また、第１の端部材２５が、芯材１９の長手方向の一方の端側（第１の端側）あって第１の定着部材２３よりもさらなる端側で、第１の定着部材２３に接するようにして、芯材１９に設置されている。 Here, the first fixing member 23 is formed in a cylindrical shape, and unevenness is formed on the outer peripheral surface. side (first end side). In addition, the first end member 25 is attached to the first fixing member 23 at one end (first end) in the longitudinal direction of the core material 19 and further to the end than the first fixing member 23 . It is installed on the core material 19 so as to be in contact with it.

これにより、接合材７が使用された部材の接合構造１では、木製の部材３（５）に衝撃力等の力が加わった場合に、棒状の芯材１９がこの長手方向で弾性変形して一時的に延び、または、塑性変形により延び、衝撃力のエネルギーを吸収するようになっている。そして、部材の接合構造１において、充填剤９と接合材７との接合部、充填剤９と木製の部材３（５）との接合部に係る応力が低減され、充填剤９の剥離等が極力防止される。 As a result, in the member joining structure 1 using the joining material 7, when a force such as an impact force is applied to the wooden member 3 (5), the rod-like core material 19 is elastically deformed in the longitudinal direction. It extends temporarily or by plastic deformation to absorb the energy of the impact force. In addition, in the member joining structure 1, the stress associated with the joining portion between the filler 9 and the joining material 7 and the joining portion between the filler 9 and the wooden member 3 (5) is reduced, and peeling of the filler 9 and the like are prevented. prevented as much as possible.

接合材７では、芯材１９の長手方向の両端部のそれぞれに、第１の定着部材２３と第２の定着部材３１とが配置されている。これにより、第１の木製の部材３と第２の木製の部材５との接合に使用されたときに、衝撃力等の力に対する第１の木製の部材３と第２の木製の部材５との接合強度を確保することができる。また、第１の定着部材２３と第２の定着部材３１との内側に位置している部位が存在することで、芯材１９の長さを確保することができ、衝撃力のエネルギーを的確に吸収することができる。 In the bonding material 7 , the first fixing member 23 and the second fixing member 31 are arranged at both ends of the core material 19 in the longitudinal direction. As a result, when used to join the first wooden member 3 and the second wooden member 5 together, the first wooden member 3 and the second wooden member 5 are protected against forces such as impact force. of the joint strength can be ensured. In addition, since there is a portion located inside the first fixing member 23 and the second fixing member 31, the length of the core member 19 can be secured, and the energy of the impact force can be accurately absorbed. can be absorbed.

ところで、接合材７において、中間材２１を削除してもよい。 By the way, in the bonding material 7, the intermediate material 21 may be omitted.

すなわち、接合材７を、棒状の芯材１９と第１の定着部材２３と第１の端部材２５とを備えた構成にしてもよい。さらに、接合材７が、第２の定着部材３１と第２の端部材３３とを備えた構成されていてもよい。 That is, the bonding material 7 may be configured to include the rod-shaped core material 19 , the first fixing member 23 and the first end member 25 . Furthermore, the bonding material 7 may be configured to include the second fixing member 31 and the second end member 33 .

また、部材の接合構造１において、上述したように、充填剤９が、中間材２１のところに設けられていなくてもよい。すなわち、充填剤９が、第１の木製の部材３の孔１１の内うちの、第１の定着部材２３と第１の端部材２５とが入り込んでいる部位のみに充填されていてもよい。また、充填剤９が、第２の木製の部材５の孔１３の内うちの、第２の定着部材３１と第２の端部材３３とが入り込んでいる部位のみに充填されていてもよい。 Further, in the member joining structure 1, the filler 9 may not be provided at the intermediate member 21 as described above. That is, the filler 9 may be filled only in the portion of the hole 11 of the first wooden member 3 where the first fixing member 23 and the first end member 25 are inserted. Alternatively, the filler 9 may be filled only in the portion of the hole 13 of the second wooden member 5 where the second fixing member 31 and the second end member 33 are inserted.

さらに説明すると、第１の木製の部材３の孔１１の内うちの中間材２１が入り込んでいる部位と、第２の木製の部材５の孔１３の内うちの中間材２１が入り込んでいる部位とには、充填剤９が入り込んでいないようにしてもよい。 To explain further, a portion of the hole 11 of the first wooden member 3 into which the intermediate member 21 is inserted and a portion of the hole 13 of the second wooden member 5 into which the intermediate member 21 is inserted. , the filler 9 may not enter.

ここで、１つ目の変形例に係る部材の接合構造１ａについて、図７、図８を参照しつつ説明する。 Here, a member joining structure 1a according to a first modification will be described with reference to FIGS. 7 and 8. FIG.

部材の接合構造１ａでは、木製の部材３（５）の孔１１（１３）の孔の形態、接合材７の中間材２１の形態が、部材の接合構造１と異なっているが、その他の箇所は、部材の接合構造１と同様に構成されている。 In the member joining structure 1a, the shape of the hole 11 (13) of the wooden member 3 (5) and the shape of the intermediate member 21 of the joining material 7 are different from those of the member joining structure 1, but other parts are different. is configured in the same manner as the member joining structure 1 .

すなわち、部材の接合構造１ａでは、第１の木製の部材３の孔１１が、奥側が小径部４９になっており手前側が大径部５１になっている。第２の木製の部材５の孔１３も、奥側が小径部４９になっており手前側が大径部５１になっている。 That is, in the member joining structure 1a, the hole 11 of the first wooden member 3 has a small diameter portion 49 on the far side and a large diameter portion 51 on the front side. The hole 13 of the second wooden member 5 also has a small diameter portion 49 on the far side and a large diameter portion 51 on the front side.

また、中間材２１の外径の値が第１の定着部材２３の外径の値および第２の定着部材３１の外径の値よりも大きくなっている。 Further, the value of the outer diameter of the intermediate member 21 is larger than the value of the outer diameter of the first fixing member 23 and the value of the outer diameter of the second fixing member 31 .

そして、中間材２１の長手方向における一部の部位が第１の木製の部材３の孔１１の大径部５１に入り込んでおり、中間材２１の残りの部位が第２の木製の部材５の孔１３の大径部５１に入り込んでいる。第１の定着部材２３と第１の端部材２５とが第１の木製の部材３の孔１１の小径部４９に入り込んでいる。また、第２の定着部材３１と第２の端部材３３とが第２の木製の部材５の孔１３の小径部に入り込んでいる。 A portion of the intermediate member 21 in the longitudinal direction is inserted into the large diameter portion 51 of the hole 11 of the first wooden member 3 , and the remaining portion of the intermediate member 21 is inserted into the second wooden member 5 . It enters the large diameter portion 51 of the hole 13 . The first anchor member 23 and the first end member 25 enter the small diameter portion 49 of the hole 11 in the first wooden member 3 . Also, the second fixing member 31 and the second end member 33 are inserted into the small diameter portion of the hole 13 of the second wooden member 5 .

充填剤９が、第１の木製の部材３の孔１１の小径部４９と第２の木製の部材５の孔１３の小径部４９とに充填されている。 A filler 9 fills the small diameter portion 49 of the hole 11 of the first wooden member 3 and the small diameter portion 49 of the hole 13 of the second wooden member 5 .

部材の接合構造１ａでは、中間材２１の外径の値と大径部５１の内径の値とはお互いが一致しているが、中間材２１の外径の値が大径部５１の内径の値よりもごくわずかに小さくっていてもよい。中間材２１の外径の値が大径部５１の内径の値よりもごくわずかに小さくっている態様では、中間材２１の外面と大径部５１の内面との間にごく僅かな間隙が形成されていることになる。このごく僅かな間隙には充填剤９で充填されておらず、ごく僅かな間隙は空洞になっている。なお、充填剤９が、中間材２１のところ（上記ごく僅かな間隙）に充填されていてもよい。 In the member joining structure 1a, the value of the outer diameter of the intermediate member 21 and the value of the inner diameter of the large diameter portion 51 match each other, but the value of the outer diameter of the intermediate member 21 is different from the inner diameter of the large diameter portion 51. It may be very slightly smaller than the value. In a mode in which the value of the outer diameter of the intermediate member 21 is slightly smaller than the value of the inner diameter of the large diameter portion 51, a very small gap is formed between the outer surface of the intermediate member 21 and the inner surface of the large diameter portion 51. It is supposed to be This very small gap is not filled with the filler 9 and is hollow. In addition, the filler 9 may be filled in the intermediate member 21 (the above very small gap).

部材の接合構造１ａでは、充填剤９が、第１の木製の部材３の孔１１の内うちの、第１の定着部材２３と第１の端部材２５とが入り込んでいる部位に充填されている。また、第２の木製の部材５の孔１３の内うちの、第２の定着部材３１と第２の端部材３３とが入り込んでいる部位に充填されている。そして、中間材２１の部位には充填剤９が存在していない。 In the member joining structure 1a, the filler 9 is filled in the portion of the hole 11 of the first wooden member 3 where the first fixing member 23 and the first end member 25 are inserted. there is Further, the portion of the hole 13 of the second wooden member 5 where the second fixing member 31 and the second end member 33 are inserted is filled. The filler 9 does not exist in the portion of the intermediate material 21 .

これにより、充填剤９が木製の部材３（５）の孔１１（１３）から溢れることを的確に防止することができる。また、第１の木製の部材３の接合面と第２の木製の部材５の接合面とを平面の状態にすることができ、第１の木製の部材３と第２の木製の部材５との接合を正確にしかも容易にすることができる。 As a result, it is possible to reliably prevent the filler 9 from overflowing from the hole 11 (13) of the wooden member 3 (5). In addition, the joint surface of the first wooden member 3 and the joint surface of the second wooden member 5 can be made flat, and the first wooden member 3 and the second wooden member 5 can be can be accurately and easily spliced.

また、部材の接合構造１ａでは、中間材２１の一部の部位が第１の木製の部材３の孔１１の大径部５１に入り込んでおり、中間材２１の残りの部位が第２の木製の部材５の孔１３の大径部５１に入り込んでいる。 Further, in the member joining structure 1a, a part of the intermediate member 21 is inserted into the large diameter portion 51 of the hole 11 of the first wooden member 3, and the remaining portion of the intermediate member 21 is the second wooden member. enters the large diameter portion 51 of the hole 13 of the member 5 of .

ここで、中間材２１の外径の値と大径部５１の内径の値とがお互いが一致するようにすれば、第１の木製の部材３に対する第２の木製の部材５の位置決めを容易にすることができる。また、第１の木製の部材３に対する第２の木製の部材５の位置ずれを防止することできる。 Here, if the value of the outer diameter of the intermediate member 21 and the value of the inner diameter of the large diameter portion 51 are made to match each other, the positioning of the second wooden member 5 with respect to the first wooden member 3 is facilitated. can be Further, positional deviation of the second wooden member 5 with respect to the first wooden member 3 can be prevented.

すなわち、第１の木製の部材３を固定した状態で第２の木製の部材５に図７に矢印Ａ３で示す方向の力（高さ方向の力）を加えたときの、第１の木製の部材３に対する状態で第２の木製の部材５の位置ずれを阻止することができる。 That is, in a state where the first wooden member 3 is fixed, when a force (force in the height direction) shown by the arrow A3 in FIG. A displacement of the second wooden member 5 relative to the member 3 can be prevented.

次に、２つ目の変形例に係る部材の接合構造１ｂについて、図９を参照しつつ説明する。 Next, a member joining structure 1b according to a second modification will be described with reference to FIG.

部材の接合構造１ｂでは、木製の部材３に金属製のコネクタ５３が設置されている点等が、部材の接合構造１と異なっているが、その他の箇所は、部材の接合構造１と同様に構成されている。 The member joining structure 1b is different from the member joining structure 1 in that a metal connector 53 is installed on the wooden member 3, but the other parts are the same as the member joining structure 1. It is configured.

すなわち、部材の接合構造１ｂは、接合材７と木製の部材３と金属製のコネクタ５３とを備えて構成されている。接合材７における芯材１９の長手方向の他方の端部（第２の端部）には、金属製のコネクタ５３に設けられている設置部５５に設置される被設置部５７が設けられている。 That is, the member joining structure 1 b is configured by including the joining material 7 , the wooden member 3 , and the metal connector 53 . At the other end (second end) of the joint material 7 in the longitudinal direction of the core material 19 is provided an installed portion 57 that is installed in the installation portion 55 provided in the metallic connector 53 . there is

被設置部５７はたとえばオスネジで構成されており、金属製のコネクタ５３に設けられている設置部（たとえばメスネジ）５５に被設置部５７のオスネジが螺合するようになっている。これにより、芯材１９（接合材７）が、金属製のコネクタ５３に一体的に設置されるようになっている。 The installed portion 57 is composed of, for example, a male screw, and the male screw of the installed portion 57 is screwed into an installation portion (for example, a female screw) 55 provided on the metallic connector 53 . As a result, the core material 19 (joining material 7) is installed integrally with the metal connector 53. As shown in FIG.

さらに説明すると、木製の部材３には、孔１１が設けられている。中間材２１と第１の定着部材２３と第１の端部材２５とが第１の木製の部材３の孔１１に入り込んでおり、被設置部５７が木製の部材３から突出している。 To further illustrate, the wooden member 3 is provided with holes 11 . The intermediate member 21 , the first fixing member 23 and the first end member 25 are inserted into the hole 11 of the first wooden member 3 , and the installed portion 57 protrudes from the wooden member 3 .

そして、被設置部５７が金属製のコネクタ５３の設置部５５に設置されており、金属製のコネクタ５３が木製の部材３に接している。なお、部材の接合構造１ｂにおける接合材７と木製の部材３と金属製のコネクタ５３との構成物を接合材付き木製部材８１と呼んでもよい。 The installation portion 57 is installed on the installation portion 55 of the metal connector 53 , and the metal connector 53 is in contact with the wooden member 3 . In addition, you may call the wooden member 81 with a joint material the structure of the joint material 7, the wooden member 3, and the metal connectors 53 in the member joint structure 1b.

さらに詳しく説明すると、木製の部材３の高さ方向の端部であって横方向の両端部には、直方体状の切り欠きが設けられている。金属製のコネクタ５３は、４つの辺状部を有する矩形な枠状に形成されており、１つの辺状部には設置部５５を構成するメスネジが形成されている。メスネジが形成されている１つの辺状部に対向する他の１つの辺状部には貫通孔５９が形成されている。 More specifically, rectangular parallelepiped cutouts are provided at the ends of the wooden member 3 in the height direction and at both ends in the horizontal direction. The metal connector 53 is formed in a rectangular frame shape having four side portions, and one side portion is provided with a female screw forming the installation portion 55 . A through-hole 59 is formed in another side-shaped portion opposite to the one side-shaped portion in which the female screw is formed.

被設置部５７を構成しているオスネジの、設置部５５を構成しているメスネジへの螺合が完了している状態では、２つの金属製のコネクタ５３のそれぞれが、木製の部材３の２つの切り欠きのそれぞれにぴったり嵌まり込んでいる。これにより、金属製のコネクタ５３が設置された木製の部材３は、切り欠きが消失した四角柱状になっている。なお、木製の部材３と金属製のコネクタ５３とがさらに接着剤等によって互いにくっついていてもよい。 In a state where the male screw forming the installation portion 57 has been completely screwed into the female screw forming the installation portion 55, each of the two metal connectors 53 is connected to the two parts of the wooden member 3. It fits perfectly in each of the two notches. As a result, the wooden member 3 on which the metal connector 53 is installed has the shape of a quadrangular prism with no cutouts.

次に図１０（ｂ）を参照しつつ、４つ目の変形例に係る部材の接合構造１ｄについて説明する。４つ目の変形例に係る部材の接合構造１ｄも、端部材２５（３３）としてナットが使用されていない点等が、部材の接合構造１と異なる。 Next, a member joining structure 1d according to a fourth modification will be described with reference to FIG. 10(b). The member joining structure 1d according to the fourth modification also differs from the member joining structure 1 in that nuts are not used as the end members 25 (33).

部材の接合構造１ｄでは接合材７が、変形部１７を構成している柱状（たとえば円柱状）の小径部６９と、定着部１５を構成している柱状（たとえば円柱状）の大径部７１とを備えて構成されている。大径部７１は、鍛造プレスなどによって柱状（たとえば円柱状）に成形されている。また、大径部７１は、小径部６９の長手方向の両端部に設けられている。大径部７１にも図示していないが凹凸が形成されている。 In the member joining structure 1d, the joining material 7 has a columnar (eg, cylindrical) small-diameter portion 69 forming the deformation portion 17 and a columnar (eg, cylindrical) large-diameter portion 71 forming the fixing portion 15. and Large-diameter portion 71 is formed into a columnar shape (for example, a columnar shape) by a forging press or the like. The large-diameter portions 71 are provided at both ends of the small-diameter portion 69 in the longitudinal direction. Although not shown, the large-diameter portion 71 is also formed with irregularities.

なお、大径部７１が、多角形柱状に形成されていてもよい。多角形柱状として三角形柱状（たとえば、底面、上面の形状が正三角である正三角柱状）、四角形柱状（たとえば、底面、上面の形状が正四角形である正四角形柱状）、以下、同様にして、五角形柱状、六角形柱状、八角形柱状等を掲げることができる。なお、大径部７１の外周にも凹凸が形成されておらず、滑らかな面（複数の平面もしくは円柱側面状の曲面）になっていてもよい。 Note that the large-diameter portion 71 may be formed in a polygonal columnar shape. Polygonal prisms include triangular prisms (e.g. equilateral triangular prisms whose bottom and top surfaces are equilateral triangles), quadrilateral prisms (e.g. equilateral quadrangular prisms whose bottom and top surfaces are equilateral triangles), and the like. A pentagonal columnar shape, a hexagonal columnar shape, an octagonal columnar shape, and the like can be mentioned. The outer circumference of the large-diameter portion 71 may also have no irregularities and may have a smooth surface (a plurality of flat surfaces or a curved surface in the shape of a cylindrical side surface).

次に、変形例に係る接合材７について図１１、図１２を参照しつつ説明する。 Next, a bonding material 7 according to a modification will be described with reference to FIGS. 11 and 12. FIG.

図１１で示す接合材７は、長手方向の両端部にオスネジ７３が形成されているスタッドボルト７５と、オスネジ７３に螺合しているナット７７とを備えて構成されている。ナット７７は、オスネジ７３の最も奥側（スタッドボルト７５の長手方向中央側）でオスネジ７３に螺合している。 The joint member 7 shown in FIG. 11 includes a stud bolt 75 having male threads 73 formed at both ends in the longitudinal direction, and a nut 77 screwed onto the male threads 73 . The nut 77 is screwed onto the male screw 73 on the innermost side of the male screw 73 (the central side in the longitudinal direction of the stud bolt 75).

図１１で示す接合材７では、スタッドボルト７５のオスネジ７３とナット７７とが定着部１５を形成しており、スタッドボルト７５の中央部（オスネジ７３が形成されていない部位）が変形部１７を形成している。 In the bonding material 7 shown in FIG. 11 , the male screw 73 of the stud bolt 75 and the nut 77 form the fixing portion 15 , and the central portion of the stud bolt 75 (the portion where the male screw 73 is not formed) forms the deformation portion 17 . forming.

図１２（ａ）で示す接合材７では、図１１で示す接合材７にさらにワッシャ８３を設けた点が、図１１で示す接合材７と異なる。ワッシャ８３は、スタッドボルト７５が貫通するようにして、オスネジ７３のところで、ナット７７に接してもしくはナット７７から僅かに離れて設けられている。また、ワッシャ８３は、スタッドボルト７５の長手方向で、ナット７７よりも中央側に位置している。 The bonding material 7 shown in FIG. 12A is different from the bonding material 7 shown in FIG. 11 in that a washer 83 is further provided on the bonding material 7 shown in FIG. The washer 83 is provided in contact with the nut 77 or slightly away from the nut 77 at the male thread 73 so that the stud bolt 75 penetrates it. Also, the washer 83 is positioned closer to the center than the nut 77 in the longitudinal direction of the stud bolt 75 .

図１２（ａ）で示す接合材７では、接合材７の左下の端部のオスネジ７３に、１つのワッシャ８３と１つのナット７７を設けてある。接合材７の右上の端部のオスネジ７３に、１つのワッシャ８３と２つのナット７７を設けてあり、ワッシャ８３を２つのナット７７で挟み込んでいる。なお、図１２（ａ）で示す接合材７において、接合材７の長手方向の両端部が、オスネジ７３に、１つのワッシャ８３と１つのナット７７を設けた構成になっていてもよいし、接合材７の長手方向の両端部が、オスネジ７３に、１つのワッシャ８３と２つのナット７７を設けた構成になっていてもよい。 In the bonding material 7 shown in FIG. 12( a ), one washer 83 and one nut 77 are provided on the male screw 73 at the lower left end of the bonding material 7 . One washer 83 and two nuts 77 are provided on the male screw 73 at the upper right end of the joint material 7 , and the washer 83 is sandwiched between the two nuts 77 . In addition, in the joint material 7 shown in FIG. 12( a ), both ends in the longitudinal direction of the joint material 7 may be configured such that one washer 83 and one nut 77 are provided on the male screw 73 , Both longitudinal ends of the bonding material 7 may have a configuration in which a male screw 73 is provided with one washer 83 and two nuts 77 .

図１２（ｂ）で示す接合材７では、図１１で示す接合材７にさらにナット７９を設けた点が、図１１で示す接合材７と異なる。ナット７９は、スタッドボルト７５の長手方向の両端でオスネジ７３に螺合している。ナット７９も定着部１５を形成している。 The bonding material 7 shown in FIG. 12(b) differs from the bonding material 7 shown in FIG. 11 in that a nut 79 is further provided on the bonding material 7 shown in FIG. The nuts 79 are screwed onto the male threads 73 at both longitudinal ends of the stud bolt 75 . The nut 79 also forms the anchorage portion 15 .

ここで、図１０（ｂ）で示すように大径部７１を設ける態様で、図１１、図１２で示すように、ナット（たとえば六角ナット）７７、７９等を設ける場合について説明する。この場合、大径部７１もしくはナット７７、７９等の引っ掛かり面積に対する接着剤９の指圧強度が、引っ張り強度以上であり、かつ、降伏強度以上になっていることが望ましい。すなわち、指圧強度＞引っ張り強度＞降伏強度以上になっていることが望ましい。ここで、引っ張り強度とは、接着剤９が充填される孔１１（１３）の径の表面積（孔が円柱状である場合には円柱の側面の面積）で確保される強度である。降伏強度とは、芯材１９の降伏強度である。指圧強度＞引っ張り強度＞降伏強度とすることで、大径部７１と接着剤９との互いの接合部が破壊される前に、スチール製の芯材１９が降伏点の強度に達することで、塑性変形を生じ、大径部７１と接着剤９とが破壊され脆性破壊が生じることとを防ぐ効果がある。 Here, a case where nuts (for example, hexagonal nuts) 77, 79 and the like are provided as shown in FIGS. In this case, it is desirable that the finger pressure strength of the adhesive 9 against the hooking area of the large-diameter portion 71 or the nuts 77, 79 is equal to or greater than the tensile strength and is equal to or greater than the yield strength. That is, it is desirable that the following relationship holds: acupressure strength>tensile strength>yield strength. Here, the tensile strength is the strength ensured by the surface area of the diameter of the hole 11 (13) filled with the adhesive 9 (when the hole is cylindrical, the area of the side surface of the cylinder). Yield strength is the yield strength of the core material 19 . By setting acupressure strength>tensile strength>yield strength, the steel core material 19 reaches the strength of the yield point before the joint between the large diameter portion 71 and the adhesive 9 is destroyed. This has the effect of preventing plastic deformation, breakage of the large-diameter portion 71 and the adhesive 9, and brittle fracture.

以上、本実施形態を説明したが、本実施形態はこれらに限定されるものではなく、本実施形態の要旨の範囲内で種々の変形が可能である。 Although the present embodiment has been described above, the present embodiment is not limited to these, and various modifications are possible within the scope of the gist of the present embodiment.
