Description
本発明は、一方の部材に設けられた一方の貫通孔と一方の部材よりもヤング係数が大きい他方の部材に設けられた他方の貫通孔とに一方の部材よりもヤング係数が大きい軸材を貫通させて部材同士が連結された構成の部材連結構造等に関する。 The present invention provides a shaft material having a larger Young's modulus than that of the one member between one through hole provided in one member and the other through hole provided in the other member having a larger Young's modulus than the one member. The present invention relates to a member connection structure in which members are connected to each other through penetration.
一方の部材としての木部材に形成された貫通孔（接合孔）と当該一方の部材よりもヤング係数が大きい他方の部材としての金属部材（金属接合プレート）に形成された貫通孔（接合孔）とにドリフトピンやボルト等の軸材を貫通させて部材同士が連結された構成の部材連結構造が知られている（特許文献１参照）。 A through hole (joint hole) formed in the wooden member as one member and a through hole (joint hole) formed in the metal member (metal joint plate) as the other member whose Young's modulus is larger than that of the one member. A member connection structure is known in which members are connected to each other by passing shaft members such as drift pins and bolts (see Patent Document 1).
従来の部材連結構造において、軸材としてドリフトピンを用いるドリフトピン工法では、一般的に、ドリフトピンを金属部材（金属接合プレート）に形成された貫通孔に強嵌合させることにより、金属製のドリフトピンと金属部材とを強固に結合する一方で、ドリフトピンを貫通孔に貫通させ易くするために、木部材に形成する貫通孔の径を金属部材に形成する貫通孔の径よりも若干大きくするようにしている。
即ち、従来の部材連結構造においては、木部材よりもヤング係数が大きい金属部材に形成された貫通孔と金属製の軸材との接触部での結合を優先しており、木部材に形成された貫通孔の内周面と軸材の外周面との接触による力の伝達が行われにくい構造となっている。
つまり、木部材よりもヤング係数が大きい金属部材の貫通孔と金属製の軸材との接触部に力が集中する構造となっているため、金属部材の負担が大きくなってしまう。
上述したように、一方の部材（木部材）に設けられた一方の貫通孔と一方の部材よりもヤング係数が大きい他方の部材（金属部材）に設けられた他方の貫通孔とに一方の部材よりもヤング係数が大きい軸材（金属軸材）を貫通させて部材同士が連結された従来の部材連結構造においては、一方の部材よりもヤング係数が大きい他方の部材に設けられた他方の貫通孔と軸材との接触部に力が集中する一方で、一方の部材に設けられた一方の貫通孔の内周面と軸材の外周面との接触による力の伝達が行われにくい構造となっているため、他方の部材の負担が大きくなってしまうという課題があった。
本発明は、一方の部材に設けられた一方の貫通孔と一方の部材よりもヤング係数が大きい他方の部材に設けられた他方の貫通孔とに軸材を貫通させて部材同士が連結された構成の部材連結構造において、一方の部材よりもヤング係数が大きい他方の部材の負担を軽減できるようにした部材連結構造等を提供するものである。
In the conventional member connection structure, the drift pin construction method uses a drift pin as the shaft material.Generally, the drift pin is tightly fitted into a through hole formed in a metal member (metal joining plate). While firmly connecting the drift pin and the metal member, in order to make it easier for the drift pin to pass through the through hole, the diameter of the through hole formed in the wooden member is made slightly larger than the diameter of the through hole formed in the metal member. That's what I do.
In other words, in the conventional member connection structure, priority is given to connection at the contact portion between the through hole formed in the metal member, which has a larger Young's modulus than that of the wooden member, and the metal shaft member, and The structure makes it difficult for force to be transmitted due to contact between the inner circumferential surface of the through hole and the outer circumferential surface of the shaft member.
In other words, since the structure is such that force is concentrated at the contact portion between the metal shaft member and the through hole of the metal member, which has a larger Young's modulus than that of the wooden member, the burden on the metal member becomes greater.
As mentioned above, one through hole provided in one member (wooden member) and the other through hole provided in the other member (metallic member) having a larger Young's modulus than that of the one member are connected to each other. In a conventional member connection structure in which members are connected by passing a shaft member (metallic shaft member) having a larger Young's modulus than that of the other member, the other member has a larger Young's modulus than that of the other member. While force is concentrated at the contact area between the hole and the shaft material, the structure is such that force is difficult to be transmitted through contact between the inner peripheral surface of one of the through holes provided in one member and the outer peripheral surface of the shaft material. Therefore, there was a problem that the burden on the other member would be increased.
In the present invention, the members are connected to each other by passing a shaft member through one through hole provided in one member and the other through hole provided in the other member having a larger Young's modulus than that of the one member. An object of the present invention is to provide a member connecting structure and the like that can reduce the burden on one member having a larger Young's modulus than the other member.
本発明に係る部材連結構造は、一方の部材に設けられた一方の貫通孔と一方の部材よりもヤング係数が大きい他方の部材に設けられた他方の貫通孔とにヤング係数が他方の部材のヤング係数と同じか又は大きい軸材を貫通させて部材同士が連結された構成の部材連結構造であって、一方の貫通孔の径は他方の貫通孔の径よりも小さく形成されて、かつ、軸材は外径が一方の貫通孔の径よりも大きく形成され、軸材が、一方の貫通孔を貫通したとともに他方の貫通孔を貫通して、軸材の外周面と一方の貫通孔の内周面とが全面接触したとともに、軸材の外周面と他方の貫通孔の内周面とが全面接触したことにより、軸材から一方の部材及び他方の部材の両方に力が伝達されるように構成されたことを特徴とする。
本発明に係る部材連結構造によれば、軸材から一方の部材及び他方の部材の両方の部材に力が伝達されるため、他方の部材の負担を軽減できる部材連結構造を提供できる。
また、一方の部材に設けられた一方の貫通孔と一方の部材よりもヤング係数が大きい他方の部材に設けられた他方の貫通孔とにヤング係数が他方の部材のヤング係数と同じか又は大きい拡径軸を貫通させて部材同士が連結された構成の部材連結構造であって、一方の貫通孔の径は他方の貫通孔の径よりも小さく形成されて、かつ、拡径軸は外径が一方の貫通孔の径よりも大きく形成され、拡径軸は、軸材と、当該軸材の周囲を囲むように設けられた管とを備え、拡径軸が、一方の貫通孔を貫通したとともに他方の貫通孔を貫通して、拡径軸の外周面と一方の貫通孔の内周面とが全面接触したとともに、拡径軸の外周面と他方の貫通孔の内周面とが全面接触したことにより、拡径軸から一方の部材及び他方の部材の両方に力が伝達されるように構成されたことを特徴とするので、拡径軸が各貫通孔の内周面に接触することにより当該各貫通孔の内周面に作用する支圧応力が軽減する。従って、拡径軸から一方の部材及び他方の部材の両方に力が伝達されるように構成されたとともに、一方の部材及び他方の部材の負担を軽減でき、しかも、強度、剛性の高い部材連結構造を提供できる。
また、軸材の外周面と管の内周面との間に充填材を備え、充填材がコンクリート又はグラウトであることを特徴とするので、一方の部材及び他方の部材に設けられた各貫通孔の内周面と拡径軸の外周面との接触面の曲率をさらに小さくできるようになるため、拡径軸の外周面と各貫通孔の内周面との接触により当該各貫通孔の内周面に作用する支圧応力をさらに小さくできる。従って、拡径軸から一方の部材及び他方の部材の両方に力が伝達されるように構成されるとともに、一方の部材及び他方の部材の負担をより軽減でき、さらに、より強度、剛性の高い部材連結構造を提供できるようになる。
また、一方の部材に設けられた一方の貫通孔と一方の部材よりもヤング係数が大きい他方の部材に設けられた他方の貫通孔とにヤング係数が他方の部材のヤング係数と同じか又は大きい拡径軸を貫通させて部材同士が連結された構成の部材連結構造であって、一方の貫通孔の径は他方の貫通孔の径よりも小さく形成されて、かつ、拡径軸は外径が一方の貫通孔の径よりも大きく形成され、拡径軸は、軸材と、当該軸材の周囲を囲むように設けられた管と、軸材の外周面と管の内周面との間に充填された軸材側充填材と、管の外周面と一方の貫通孔の内周面及び他方の貫通孔の内周面との間に充填された貫通孔側充填材とを備え、軸材側充填材及び貫通孔側充填材がコンクリート又はグラウトであり、拡径軸が、一方の貫通孔を貫通したとともに他方の貫通孔を貫通して、拡径軸の外周面と一方の貫通孔の内周面とが全面接触したとともに、拡径軸の外周面と他方の貫通孔の内周面とが全面接触したことにより、拡径軸から一方の部材及び他方の部材の両方に力が伝達されるように構成されたことを特徴とするので、拡径軸の外周面と各貫通孔の内周面との接触により当該各貫通孔の内周面に作用する支圧応力をさらに小さくできる。従って、拡径軸から一方の部材及び他方の部材の両方に力が伝達されるように構成されるとともに、一方の部材及び他方の部材の負担をより軽減でき、さらに、より強度、剛性の高い部材連結構造を提供できるようになる。
また、一方の部材と他方の部材との接触面が、凹凸面であるので、各部材相互間の位置ずれ防止効果が向上して、貫通孔相互間の位置ずれ防止効果が向上するので、金属部材の貫通孔と軸材との接触部の負担軽減効果、及び、各部材の各貫通孔の内周面に作用する支圧応力軽減効果を向上できる。
また、一方の部材が木部材であり、他方の部材が金属部材であることを特徴とするので、金属部材の負担を軽減できる部材連結構造を提供できる。
本発明に係る上述した部材連結構造の製造方法は、外径が一方の貫通孔の径よりも大きい軸材を、一方の貫通孔に貫通させるとともに他方の貫通孔に貫通させることにより、軸材の外周面と一方の貫通孔の内周面とを全面接触させるとともに、軸材の外周面と他方の貫通孔の内周面とを全面接触させたことを特徴とするので、軸材から一方の部材及び他方の部材の両方の部材に力が伝達されて、他方の部材の負担を軽減できる部材連結構造を確実かつ容易に製造できるようになる。

Due to the full contact between the inner circumferential surface and the full contact between the outer circumferential surface of the shaft member and the inner circumferential surface of the other through hole, force is transmitted from the shaft member to both one member and the other member. It is characterized by being configured as follows .
According to the member connecting structure according to the present invention, since force is transmitted from the shaft member to both the one member and the other member, it is possible to provide a member connecting structure that can reduce the burden on the other member.
In addition, one through hole provided in one member and the other through hole provided in the other member having a larger Young's modulus than that of the one member have a Young's modulus that is the same as or larger than the Young's modulus of the other member.

At the same time, it penetrated through the other through hole, and the outer peripheral surface of the expanded diameter shaft and the inner peripheral surface of one of the through holes came into full contact, and the outer peripheral surface of the expanded diameter shaft and the inner peripheral surface of the other through hole came into full contact. The diameter expanding shaft contacts the inner circumferential surface of each through hole because the diameter expanding shaft is configured so that force is transmitted to both one member and the other member by full contact. By doing so, the bearing stress acting on the inner circumferential surface of each through hole is reduced. Therefore, the configuration is such that force is transmitted from the enlarged diameter shaft to both one member and the other member, the burden on one member and the other member can be reduced, and the member connection is high in strength and rigidity. It can provide structure.
In addition, a filling material is provided between the outer peripheral surface of the shaft member and the inner peripheral surface of the pipe, and the filling material is concrete or grout, so that each penetration provided in one member and the other member is Since the curvature of the contact surface between the inner circumferential surface of the hole and the outer circumferential surface of the enlarged diameter shaft can be further reduced, the contact between the outer circumferential surface of the enlarged diameter shaft and the inner circumferential surface of each through hole increases the The bearing stress acting on the inner peripheral surface can be further reduced. Therefore, the configuration is such that force is transmitted from the enlarged diameter shaft to both one member and the other member, the burden on one member and the other member can be further reduced, and the structure has higher strength and rigidity. It becomes possible to provide a member connection structure.
In addition, one through hole provided in one member and the other through hole provided in the other member having a larger Young's modulus than that of the one member have a Young's modulus that is the same as or larger than the Young's modulus of the other member. This is a member connection structure in which members are connected to each other by penetrating an expanded diameter shaft, and the diameter of one through hole is smaller than the diameter of the other through hole, and the expanded diameter shaft has an outer diameter. is formed to be larger than the diameter of one of the through-holes, and the enlarged diameter shaft is formed by connecting the shaft member, the pipe provided so as to surround the shaft member, and the outer circumferential surface of the shaft member and the inner circumferential surface of the pipe.

Because the inner circumferential surface of the hole was in full contact with the outer circumferential surface of the expanded diameter shaft and the inner circumferential surface of the other through hole was in full contact, force was applied from the expanded diameter shaft to both one member and the other member. The bearing stress acting on the inner circumferential surface of each through hole due to contact between the outer circumferential surface of the expanded diameter shaft and the inner circumferential surface of each through hole is further reduced. Can be made smaller. Therefore, the configuration is such that force is transmitted from the enlarged diameter shaft to both one member and the other member, the burden on one member and the other member can be further reduced, and the structure has higher strength and rigidity. It becomes possible to provide a member connection structure.
In addition, since the contact surface between one member and the other member is an uneven surface, the effect of preventing misalignment between each member is improved, and the effect of preventing misalignment between through holes is improved. It is possible to improve the effect of reducing the load on the contact portion between the through hole of the member and the shaft material, and the effect of reducing the bearing pressure stress acting on the inner circumferential surface of each through hole of each member.

For example, in FIG. 1(a), a wooden member as one member A is sandwiched between a metal member as the other member B, and one through hole H1 provided in the wooden member and the metal member provided in the metal member are connected. A double-ended screw shaft, which is a metal member serving as the shaft material C, is passed through the other through-hole H2, and a washer E1 and a nut E2 are fastened to the threaded portions at both ends of the double-ended screw shaft, respectively, to connect the wooden member and the metal member. It is a connected member connection structure.
Further, FIG. 1(b) shows that a metal member as the other member B is inserted into a groove A1 formed in a wooden member as one member A, and one through hole H1 provided in the wooden member is connected to the metal member. A double-ended threaded shaft, which is a metal member serving as the shaft material C, is passed through the other through-hole H2 provided in the member, and a washer E1 and a nut E2 are fastened to the screw portions at both ends of the double-ended threaded shaft, respectively, to form a wooden member. This is a member connection structure in which the metal member and the metal member are connected.
Further, FIG. 1(c) shows a state in which a wooden member as one member A and a metal member as the other member B are placed next to each other, and one through hole H1 provided in the wooden member and a through hole H1 provided in the metal member are arranged side by side. A double-end screw shaft, which is a metal member serving as the shaft member C, is passed through the other through-hole H2, and a washer E1 and a nut E2 are fastened to the threaded portions at both ends of the double-end screw shaft, respectively, to connect the wooden member and the metal member. This is a member connection structure that connects the
尚、軸材Ｃとしての両端ねじ軸は、両端のねじ部以外の軸部が貫通孔内に配置されて貫通孔の外側に配置された両端のねじ部にナットＥ２が締結されることで固定される。 In addition, the shaft with screws at both ends as the shaft material C is fixed by having the shaft portions other than the threaded portions at both ends placed inside the through hole and tightening nuts E2 to the screw portions at both ends placed outside the through hole. be done.
実施形態１に係る部材連結構造によれば、軸材Ｃの外周面Ｄと一方の貫通孔Ｈ１の内周面とが全面接触するとともに、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面とが全面接触して、軸材Ｃから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成されているため、従来のように、一方の部材よりもヤング係数が大きい他方の部材（金属部材）に形成された他方の貫通孔と軸材との接触部に力が集中して、他方の部材の負担が大きくなってしまうことを防止でき、他方の部材Ｂの負担を軽減できる部材連結構造を提供できる。
言い換えれば、一方の部材Ａの負担及び他方の部材Ｂの負担を均すことができるようになり、各部材（一方の部材Ａ及び他方の部材Ｂ）と軸材Ｃとの間での力の伝達が安定かつ良好に行われるようになって、他方の部材Ｂの負担を軽減できる部材連結構造となる。
According to the member connection structure according to the first embodiment, the outer peripheral surface D of the shaft member C and the inner peripheral surface of one of the through holes H1 are in full contact with each other, and the outer peripheral surface D of the shaft member C and the inner peripheral surface of the other through hole H2 are in full contact with each other. Since it is configured so that the shaft member C is in full contact with the inner circumferential surface and force is transmitted from the shaft member C to both one member A and the other member B, it is younger than one member as in the conventional case. It is possible to prevent force from concentrating on the contact area between the other through hole formed in the other member (metal member) with a larger coefficient and the shaft member, and increasing the burden on the other member. It is possible to provide a member connection structure that can reduce the burden on B.
In other words, the burden on one member A and the burden on the other member B can be equalized, and the force between each member (one member A and the other member B) and the shaft member C can be reduced. Transmission is performed stably and satisfactorily, resulting in a member connection structure that can reduce the burden on the other member B.
特に、一方の部材Ａが木部材であり、他方の部材Ｂが金属プレート等の金属部材であり、軸材Ｃが円柱棒状の金属部材である場合、例えば、図１（ａ），（ｂ）に示すように、木部材に形成された一方の貫通孔Ｈ１の内周面と軸材Ｃの外周面Ｄとの接触面積が大きく、かつ、金属部材に形成された他方の貫通孔Ｈ２の内周面と軸材Ｃの外周面Ｄとの接触面積が小さい構成の部材連結構造となり、軸材Ｃの外周面Ｄと接触する面積が大きい木部材が大きな力を負担できるようになるとともに、軸材Ｃの外周面Ｄと接触する面積が小さい金属部材に負担させる力を小さくすることができるようになるので、金属プレート等の金属部材（他方の部材Ｂ）の負担を軽減できる部材連結構造を提供できるようになる。 In particular, when one member A is a wooden member, the other member B is a metal member such as a metal plate, and the shaft member C is a cylindrical rod-shaped metal member, for example, FIGS. As shown in FIG. The component connection structure has a small contact area between the circumferential surface and the outer circumferential surface D of the shaft member C, and the wooden member having a large contact area with the outer circumferential surface D of the shaft member C can bear a large force. Since it becomes possible to reduce the force borne by the metal member whose area is small in contact with the outer circumferential surface D of the material C, a member connection structure that can reduce the burden on the metal member such as the metal plate (the other member B) is created. be able to provide it.

When a predetermined force is applied, the outer circumferential surface D of the shaft member C contacts the inner circumferential surface of the other through hole H2, and force is applied from the shaft member C to both one member A and the other member B. It was configured to be transmitted.
尚、図２に示すように、軸材Ｃの外径ｄ、一方の部材Ａに形成された一方の貫通孔Ｈ１の径ｄ１、他方の部材Ｂに形成された他方の貫通孔Ｈ２の径ｄ２とした場合、各径の大小関係は、ｄ２＞ｄ≧ｄ１とした。 As shown in FIG. 2, the outer diameter d of the shaft member C, the diameter d1 of one through hole H1 formed in one member A, and the diameter d2 of the other through hole H2 formed in the other member B. In this case, the size relationship of each diameter is d2>d≧d1.
即ち、実施形態２に係る部材連結構造では、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面との間に若干の隙間が生じるように構成され、部材連結構造に力が加わっていない状態では、軸材Ｃから他方の部材Ｂに力が伝達されない構造となっているが、例えば地震等の強い力が部材連結構造に加わることにより、軸材Ｃから一方の貫通孔Ｈ１の内周面に所定の力が加わった場合に、一方の貫通孔Ｈ１の内周面が軸材Ｃで押圧されて変形することにより、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面とが接触して、軸材Ｃから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成した。 That is, the member connecting structure according to the second embodiment is configured such that a slight gap is generated between the outer circumferential surface D of the shaft member C and the inner circumferential surface of the other through hole H2, so that force is not applied to the member connecting structure. When not connected, the structure is such that no force is transmitted from the shaft member C to the other member B, but if a strong force, such as an earthquake, is applied to the member connection structure, the shaft member C may transfer force from the shaft member C to the other through hole H1. When a predetermined force is applied to the inner circumferential surface, the inner circumferential surface of one of the through holes H1 is pressed and deformed by the shaft material C, thereby causing the outer circumferential surface D of the shaft material C and the inner surface of the other through hole H2 to The shaft member C is configured so that force is transmitted to both one member A and the other member B by contacting the peripheral surfaces thereof.
従って、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面との間に生じる隙間、即ち、ｄ２－ｄは、できるだけ小さい方が好ましいため、例えば、数ｍｍ以下、好ましくは、１ｍｍ以下にする。 Therefore, the gap generated between the outer circumferential surface D of the shaft member C and the inner circumferential surface of the other through hole H2, that is, d2-d, is preferably as small as possible, for example, several mm or less, preferably 1 mm. Do the following.
実施形態２に係る部材連結構造によれば、例えば、地震時等において、軸材Ｃから一方の貫通孔Ｈ１の内周面に所定の力が加わった場合に、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面とが接触して、軸材Ｃから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるので、一方の部材（例えば金属部材）Ａよりもヤング係数が大きい他方の部材（例えば木部材）Ｂに形成された他方の貫通孔Ｈ２と軸材Ｃとの接触部に力が集中して、他方の部材Ｂの負担が大きくなってしまうことを防止でき、他方の部材Ｂの負担を軽減できる部材連結構造を提供できる。 According to the member connection structure according to the second embodiment, when a predetermined force is applied from the shaft C to the inner peripheral surface of one of the through holes H1 during an earthquake, for example, the outer peripheral surface D of the shaft C and the Since the inner peripheral surface of the other through hole H2 contacts and force is transmitted from the shaft member C to both one member A and the other member B, one member (for example, a metal member) is younger than the other member A. Prevents force from being concentrated at the contact area between the other through hole H2 formed in the other member B (for example, a wooden member) with a larger coefficient and the shaft member C, and increasing the burden on the other member B. It is possible to provide a member connection structure that can reduce the burden on the other member B.
実施形態３
一方の部材Ａに設けられた一方の貫通孔Ｈ１と一方の部材Ａよりもヤング係数が大きい他方の部材Ｂに設けられた他方の貫通孔Ｈ２とに一方の部材Ａよりもヤング係数が大きい軸材Ｃを貫通させて部材Ａ，Ｂ同士が連結され、軸材Ｃから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成された部材連結構造の製造方法は、図３に示すように、外径ｄが一方の貫通孔Ｈ１の径ｄ１よりも大きい軸材Ｃを、一方の貫通孔Ｈ１に貫通させるとともに他方の貫通孔Ｈ２に貫通させることにより、軸材Ｃの外周面Ｄと一方の貫通孔Ｈ１の内周面とを全面接触させるとともに、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面とを全面接触させた構成の部材連結構造を製造するようにした。
Embodiment 3
One through hole H1 provided in one member A and the other through hole H2 provided in the other member B, which has a larger Young's modulus than one member A, have a shaft with a larger Young's modulus than one member A. A manufacturing method of a member connection structure configured such that members A and B are connected to each other by penetrating material C and force is transmitted from shaft member C to both one member A and the other member B is shown in FIG. 3, by passing a shaft material C whose outer diameter d is larger than the diameter d1 of one of the through holes H1 into one of the through holes H1 and through the other through hole H2, the shaft material C. Manufacture a member connection structure in which the outer circumferential surface D and the inner circumferential surface of one through hole H1 are in full contact with each other, and the outer circumferential surface D of the shaft material C and the inner circumferential surface of the other through hole H2 are in full contact with each other. I decided to do so.
例えば、図３に示すように、軸材Ｃの外径ｄ、一方の部材Ａに形成された一方の貫通孔Ｈ１の径ｄ１、他方の部材Ｂに形成された他方の貫通孔Ｈ２の径ｄ２の関係を、ｄ２＝ｄ＞ｄ１とし、軸材Ｃを一方の貫通孔Ｈ１及び他方の貫通孔Ｈ２に圧入して貫通させることにより、軸材Ｃの外周面Ｄと一方の貫通孔Ｈ１の内周面とが全面接触するとともに、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面とが全面接触する構成の部材連結構造を製造するようにした（図１参照）。 For example, as shown in FIG. 3, the outer diameter d of the shaft material C, the diameter d1 of one through hole H1 formed in one member A, and the diameter d2 of the other through hole H2 formed in the other member B. By setting the relationship d2=d>d1 and press-fitting the shaft material C into one of the through holes H1 and the other through hole H2, the outer circumferential surface D of the shaft material C and the inner surface of one of the through holes H1 are A member connecting structure was manufactured in which the outer circumferential surface D of the shaft member C and the inner circumferential surface of the other through hole H2 were in full contact with each other (see FIG. 1).
尚、この場合、軸材Ｃの挿入側先端は、貫通孔Ｈ１に挿入しやすくするために，面取り加工を施すことにより、一方の貫通孔Ｈ１の径ｄ１よりも小径の小径部ｅに形成しておくことが好ましい。 In this case, in order to facilitate insertion into the through hole H1, the insertion side tip of the shaft material C is chamfered to form a small diameter portion e that is smaller than the diameter d1 of one of the through holes H1. It is preferable to keep it.
実施形態３に係る部材連結構造の製造方法によれば、外径ｄが一方の貫通孔Ｈ１の径ｄ１よりも大きい軸材Ｃを、一方の貫通孔Ｈ１に貫通させるとともに他方の貫通孔Ｈ２に貫通させたので、軸材Ｃの外周面Ｄと一方の貫通孔Ｈ１の内周面とが全面接触するとともに、軸材Ｃの外周面Ｄと他方の貫通孔Ｈ２の内周面とが全面接触して、軸材Ｃから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成されて、他方の部材Ｂの負担を軽減できる部材連結構造を確実かつ容易に製造できる。 According to the method for manufacturing a member connection structure according to the third embodiment, a shaft member C having an outer diameter d larger than the diameter d1 of one of the through holes H1 is passed through one of the through holes H1 and is inserted into the other through hole H2. Since it is penetrated, the outer circumferential surface D of the shaft material C and the inner circumferential surface of one of the through holes H1 are in full contact with each other, and the outer circumferential surface D of the shaft material C and the inner circumferential surface of the other through hole H2 are in full contact with each other. In this way, it is possible to reliably and easily manufacture a member connection structure configured such that force is transmitted from the shaft member C to both one member A and the other member B, and which can reduce the burden on the other member B.
特に、一方の部材Ａが木部材、軸材Ｃが両端ねじ軸等の金属部材、他方の部材Ｂが金属プレート等の金属部材であれば、両端ねじ軸の軸部（両端のねじ部以外の部分）が木部材に形成された一方の貫通孔Ｈ１の内面に食い込む圧力(摩擦力)で当該木部材に固定される、所謂、シマリバメと呼ばれる状態となって、両端ねじ軸（軸材Ｃ）の軸部と木部材（一方の部材Ａ）との一体性が高まることから、例えば金属プレート（他方の部材Ｂ）の負担を軽減できる部材連結構造となる。 In particular, if one member A is a wooden member, shaft material C is a metal member such as a double-end threaded shaft, and the other member B is a metal member such as a metal plate, the shaft portion of the double-end screw shaft (other than the threaded portions at both ends) The threaded shaft (shaft C) at both ends is fixed to the wooden member by pressure (frictional force) that bites into the inner surface of one of the through-holes H1 formed in the wooden member. Since the integrity of the shaft portion and the wooden member (one member A) is enhanced, a member connection structure is achieved that can reduce the burden on, for example, the metal plate (the other member B).

Embodiment 4
The member connecting structure and the manufacturing method of the member connecting structure according to Embodiment 4 are different from the member connecting structure described in Embodiment 1 and Embodiment 2 and the manufacturing method of the member connecting structure described in Embodiment 3. The structure is such that an intermediate member F is provided between member A and the other member B.
Note that in FIGS. 4(a) to 4(c), the same or equivalent parts as in FIGS. 1(a) to 1(c) are designated by the same reference numerals, and the description thereof will be omitted.
例えば、図４（ａ）乃至図４（ｃ）に示すように、一方の部材Ａに設けられた貫通孔Ｈ１と他方の部材Ｂに設けられた貫通孔Ｈ２と中間部材Ｆに設けられた貫通孔Ｈ３とに軸材Ｃとしての両端ねじ軸を貫通させて当該両端ねじ軸の両端のねじ部にそれぞれ座金Ｅ１及びナットＥ２を締結して一方の部材Ａと他方の部材Ｂとを連結したことにより、軸材Ｃから、一方の部材Ａ、他方の部材Ｂ、中間部材Ｆの全ての部材に力が伝達されるように構成した。 For example, as shown in FIGS. 4(a) to 4(c), a through hole H1 provided in one member A, a through hole H2 provided in the other member B, and a through hole provided in an intermediate member F. One member A and the other member B are connected by passing a screw shaft at both ends as the shaft material C through hole H3 and fastening a washer E1 and a nut E2 to the screw portions at both ends of the screw shaft at both ends. Thus, the structure is such that force is transmitted from the shaft member C to all the members, one member A, the other member B, and the intermediate member F.
尚、中間部材Ｆとしては、ヤング係数が、一方の部材Ａを形成する木部材のヤング係数以上で、かつ、他方の部材Ｂを形成する金属部材のヤング係数以下の部材を用いることが好ましく、例えば、樹脂部材、金属部材、木部材等を用いればよい。
また、中間部材Ｆに設けられた貫通孔Ｈ３の径は、一方の部材Ａの径と同径にすればよい。
As the intermediate member F, it is preferable to use a member whose Young's modulus is greater than or equal to the Young's modulus of the wooden member forming one member A and less than or equal to the Young's modulus of the metal member forming the other member B. For example, a resin member, a metal member, a wooden member, etc. may be used.
Further, the diameter of the through hole H3 provided in the intermediate member F may be the same as the diameter of one member A.
実施形態４に係る部材連結構造及び当該部材連結構造の製造方法によれば、軸材Ｃから一方の部材Ａ、他方の部材Ｂ、中間部材Ｆの全ての部材に力が伝達されるように構成したため、他方の部材Ｂの負担を軽減できる部材連結構造及び当該部材連結構造の製造方法を提供できる。 According to the member connecting structure and the manufacturing method of the member connecting structure according to Embodiment 4, the configuration is such that force is transmitted from the shaft member C to all members, one member A, the other member B, and the intermediate member F. Therefore, it is possible to provide a member connecting structure that can reduce the burden on the other member B, and a method for manufacturing the member connecting structure.

Embodiment 5
The member connecting structure and the manufacturing method of the member connecting structure according to Embodiment 5 are the same as those described above in the member connecting structure described in Embodiment 1 and Embodiment 2, and the manufacturing method of the member connecting structure described in Embodiment 3. Instead of the shaft material C, as shown in FIGS. 5(a) to 5(c), the pipe C1 is provided to surround the shaft material C and the shaft material C. The enlarged diameter shaft CA, that is, the enlarged diameter shaft CA whose diameter is larger than that of the shaft member C is used.
Note that in FIGS. 5(a) to 5(c), the same or equivalent parts as in FIGS. 1(a) to 1(c) are denoted by the same reference numerals, and the description thereof will be omitted.
例えば、図５（ａ）乃至図５（ｃ）に示すように、一方の部材Ａに設けられた貫通孔Ｈ１Ａと他方の部材Ｂに設けられた貫通孔Ｈ２Ａとに拡径軸ＣＡを貫通させて当該拡径軸ＣＡの両端に設けられて貫通孔Ｈ１Ａ，Ｈ２Ａの外側に配置された両端のねじ部にそれぞれ座金Ｅ１及びナットＥ２を締結して一方の部材Ａと他方の部材Ｂとを連結したことにより、軸材Ｃから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成した。 For example, as shown in FIGS. 5(a) to 5(c), the enlarged diameter shaft CA is passed through a through hole H1A provided in one member A and a through hole H2A provided in the other member B. One member A and the other member B are connected by fastening a washer E1 and a nut E2 to the threaded portions at both ends of the enlarged diameter shaft CA and arranged on the outside of the through holes H1A and H2A, respectively. As a result, force is transmitted from the shaft member C to both the member A on one side and the member B on the other side.
実施形態５に係る部材連結構造及び当該部材連結構造の製造方法によれば、拡径軸ＣＡから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成されたので、他方の部材Ｂの負担を軽減できる部材連結構造及び当該部材連結構造の製造方法を提供できる。 According to the member connecting structure and the manufacturing method of the member connecting structure according to Embodiment 5, since the structure is such that force is transmitted from the expanded diameter axis CA to both one member A and the other member B, the other member It is possible to provide a member connecting structure that can reduce the burden on member B, and a method for manufacturing the member connecting structure.
さらに、実施形態５によれば、一方の部材Ａ及び他方の部材Ｂに設けられた各貫通孔Ｈ１Ａ，Ｈ２Ａの内周面と拡径軸ＣＡの外周面ＤＡとの接触面の曲率を小さくできるので、拡径軸ＣＡが各貫通孔Ｈ１Ａ，Ｈ２Ａの内周面に接触することにより当該各貫通孔Ｈ１Ａ，Ｈ２Ａの内周面に作用する支圧応力が軽減する。従って、拡径軸ＣＡから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成されたとともに、一方の部材Ａ及び他方の部材Ｂの負担を軽減でき、しかも、強度、剛性の高い部材連結構造、及び、当該部材連結構造の製造方法を提供できる。 Furthermore, according to the fifth embodiment, the curvature of the contact surface between the inner circumferential surface of each of the through holes H1A and H2A provided in one member A and the other member B and the outer circumferential surface DA of the enlarged diameter shaft CA can be reduced. Therefore, the bearing stress acting on the inner circumferential surfaces of the respective through holes H1A, H2A is reduced by the expanded diameter axis CA coming into contact with the inner circumferential surfaces of the respective through holes H1A, H2A. Therefore, the configuration is such that force is transmitted from the expanded diameter axis CA to both the one member A and the other member B, and the burden on the one member A and the other member B can be reduced. It is possible to provide a highly rigid member connecting structure and a method for manufacturing the member connecting structure.

Due to the contact with the inner circumferential surface of each of the through holes H1B and H2B, the bearing stress acting on the inner circumferential surface of each of the through holes H1B and H2B can be made even smaller than in the fifth and sixth embodiments. Therefore, the configuration is such that force is transmitted from the expanded diameter axis CAX to both one member A and the other member B, and the burden on one member A and the other member B can be further reduced. It becomes possible to provide a member connecting structure with high strength and rigidity, and a method for manufacturing the member connecting structure.
実施形態８
上述した拡径軸ＣＡの代わりに、図８に示すような、拡径軸ＣＡＹを用いても良い。
当該拡径軸ＣＡＹは、軸材Ｃと、軸材Ｃの周囲を囲むように設けられた管Ｃ２と、当該軸材Ｃの外周面と管Ｃ２の内周面との間に充填されたコンクリートやグラウト等の充填材である軸材側充填材Ｃ３と、管Ｃ２の外周面と貫通孔Ｈ１Ｃ，Ｈ２Ｃの内周面との間に充填されたコンクリートやグラウト等の充填材である貫通孔側充填材Ｃ４とで構成された拡径軸とした。
Embodiment 8
Instead of the above-mentioned enlarged diameter axis CA, an enlarged diameter axis CAY as shown in FIG. 8 may be used.
The expanded diameter axis CAY consists of a shaft C, a pipe C2 provided to surround the shaft C, and concrete filled between the outer peripheral surface of the shaft C and the inner peripheral surface of the pipe C2. The shaft member side filler C3 is a filler such as or grout, and the through-hole side is a filler such as concrete or grout filled between the outer circumferential surface of the pipe C2 and the inner circumferential surface of the through holes H1C and H2C. The expanded diameter shaft was made of filler C4.
実施形態８に係る部材連結構造、及び、当該部材連結構造の製造方法によれば、拡径軸ＣＡＸを用いたので、拡径軸ＣＡＹの外周面ＤＣと各貫通孔Ｈ１Ｃ，Ｈ２Ｃの内周面との接触により当該各貫通孔Ｈ１Ｃ，Ｈ２Ｃの内周面に作用する支圧応力を実施形態７よりもさらに小さくできる。従って、拡径軸ＣＡＹから一方の部材Ａ及び他方の部材Ｂの両方に力が伝達されるように構成されるとともに、一方の部材Ａ及び他方の部材Ｂの負担をより軽減でき、さらに、より強度、剛性の高い部材連結構造、及び、当該部材連結構造の製造方法を提供できるようになる。 According to the member connecting structure and the manufacturing method of the member connecting structure according to Embodiment 8, since the enlarged diameter axis CAX is used, the outer circumferential surface DC of the enlarged diameter axis CAY and the inner circumferential surface of each through hole H1C, H2C. The bearing stress acting on the inner circumferential surface of each of the through holes H1C and H2C can be made even smaller than in the seventh embodiment. Therefore, the configuration is such that force is transmitted from the expanded diameter axis CAY to both one member A and the other member B, and the burden on one member A and the other member B can be further reduced. It becomes possible to provide a member connecting structure with high strength and rigidity, and a method for manufacturing the member connecting structure.
実施形態９
一方の部材Ａ（例えば木部材）と他方の部材Ｂ（例えば金属部材）との接触面、一方の部材Ａ（例えば木部材）と中間部材Ｆ（例えば樹脂部材）との接触面、他方の部材Ｂ（例えば金属部材）と中間部材Ｆ（例えば樹脂部材）との接触面を、凹凸面に形成すれば、各部材相互間の位置ずれ防止効果が向上して、貫通孔相互間の位置ずれ防止効果が向上するので、金属部材の貫通孔と軸材との接触部の負担軽減効果、及び、各部材の各貫通孔の内周面に作用する支圧応力軽減効果を向上できる。
Embodiment 9
The contact surface between one member A (for example, a wooden member) and the other member B (for example, a metal member), the contact surface between one member A (for example, a wooden member) and an intermediate member F (for example, a resin member), the other member If the contact surface between B (for example, a metal member) and the intermediate member F (for example, a resin member) is formed into an uneven surface, the effect of preventing misalignment between each member will be improved, and the misalignment between through holes will be prevented. Since the effect is improved, the effect of reducing the burden on the contact portion between the through hole of the metal member and the shaft member and the effect of reducing the bearing pressure stress acting on the inner circumferential surface of each through hole of each member can be improved.
尚、拡径軸ＣＡの管Ｃ１、拡径軸ＣＡＸ，ＣＡＹの管Ｃ２は、各貫通孔を貫通して両端が各部材の外面よりも外側に突出しないで各部材の外面と同一平面上に位置されるような管長のものを用いることが好ましい。
また、拡径軸ＣＡ，ＣＡＸ，ＣＡＹの外径寸法を、軸材Ｃの外径寸法の数倍、例えば、１．５倍以上に設定することにより、一方の部材Ａ及び他方の部材Ｂに設けられた各貫通孔の内周面と拡径軸の外周面との接触面の曲率を小さくできるようになるため、拡径軸の外周面と各貫通孔の内周面との接触により当該各貫通孔の内周面に作用する支圧応力をより小さくできる。
In addition, the pipe C1 with the enlarged diameter axis CA and the pipe C2 with the enlarged diameter axes CAX and CAY pass through each through hole so that both ends do not protrude beyond the outer surface of each member and are on the same plane as the outer surface of each member. It is preferable to use a tube with a length that allows the tube to be positioned.
In addition, by setting the outer diameter of the enlarged diameter shafts CA, CAX, and CAY to several times the outer diameter of the shaft material C, for example, 1.5 times or more, one member A and the other member B can be Since the curvature of the contact surface between the inner circumferential surface of each provided through-hole and the outer circumferential surface of the enlarged diameter shaft can be reduced, the contact between the outer circumferential surface of the enlarged diameter shaft and the inner circumferential surface of each through hole makes it possible to The bearing stress acting on the inner circumferential surface of each through hole can be further reduced.
また、軸材Ｃとしては、両端ねじ軸の代わりに、ドリフトピン等の軸材を用いてもよい。
また、上述した「外周面と内周面との全面接触」とは、完全な全面接触だけでなく、例えば、外周面の一部又は内周面の一部に窪み部分等が存在して、当該一部の窪み部分等が接触していないような場合も含む。
Further, as the shaft member C, a shaft member such as a drift pin may be used instead of the shaft with screws at both ends.
Furthermore, the above-mentioned "full-surface contact between the outer circumferential surface and the inner circumferential surface" does not mean complete full-surface contact, but also, for example, when there is a depression or the like on a part of the outer circumferential surface or a part of the inner circumferential surface. This also includes cases where some of the recesses are not in contact with each other.
