本発明は、木材からなる一方側被接合部材と種々の素材からなる他方側被接合部材とを接合する技術に関する。 The present invention relates to a technique for joining one side joined member made of wood and the other side joined member made of various materials.
従来、この種の技術としては、木柱(木材からなる一方側被接合部材の一例)と、木柱に接合される木柱用被接合片部と木梁に接合される木梁用接合片部とを備える金属製の継手部材(前記他方側被接合部材の一例)との接合に関して、以下(1)、(2)に記載のものが知られている。 Conventionally, as this kind of technology, a wooden pole (an example of a member to be joined on one side made of wood), a wooden pole piece to be joined to a wooden pole, and a wooden beam joint to be joined to a wooden beam The following (1) and (2) are known for joining to a metal joint member (an example of the other-side joined member) including a portion.

(2)前記継手部材の木柱用被接合片部2aに貫通形成された挿通孔2dを通して、頭付きの木ネジ4の頭部4aで木柱用被接合片部2aを前記木柱1に押し付けるように、木ネジ4のネジ部4bを木柱1に螺入することにより、木柱1と木柱用被接合片部2aとが接合されているもの(図12(a)参照)。
(2) The wood pole to-be-joined
ところが、木材は、時間の経過に伴う含水率の低下によってどうしても多少の収縮変形が生じることから、前記(1)の技術では、図11(b)に示すように、時間の経過に伴う一方側被接合部材の収縮変形長さSの範囲で両接合部材が遠近方向に遊動可能な状態に両被接合部材の接合部が緩くなって、そのことで、木柱と木梁との架構の剛性が不十分になる問題がある。 However, since the wood is inevitably contracted and deformed due to a decrease in the moisture content with the passage of time, the technique of (1), as shown in FIG. In the range of the contraction deformation length S of the members to be joined, the joint parts of both the members to be joined are loosened in a state where both the members can be moved freely in the perspective direction, so that the rigidity of the frame between the wooden pillar and the wooden beam is reduced. There is a problem that becomes insufficient.
また、前記(2)の技術でも、図12(b)に示すように、時間の経過に伴う一方側被接合部材の収縮変形長さSの範囲で他方側被接合部材が一方側被接合部材に対する遠近方向に遊動可能な状態に両被接合部材の接合が緩くなって、やはり、木柱と木梁との架構の剛性が不十分になる問題がある。 Also in the technique (2), as shown in FIG. 12B, the other-side bonded member is within the range of the contraction deformation length S of the one-side bonded member over time, as shown in FIG. However, there is a problem in that the rigidity of the frame structure between the wooden pillar and the wooden beam becomes insufficient because the joining of both the members to be joined becomes loose in a state in which it can move freely in the perspective direction.
そして、上記の問題は、例えば、木構造の架構にあっては筋交いを不存とする形態での開口部の大型化を困難にする等、木材の使用用途が制限される重大な要因になっていた。 The above problem becomes a serious factor that restricts the use of wood, such as making it difficult to increase the size of the opening in a form that does not require bracing in a wooden structure. It was.
本発明は、上述の如き課題に鑑みてなされたものであって、その主たる課題は、時間の経過に伴う木材からなる一方側被接合部材の収縮変形によって両被接合部材の接合部に緩みが生じるのを効果的に抑止し得る部材接合構造、及び、木柱と木梁との接合構造、並びに、接合具を提供する点にある。 The present invention has been made in view of the problems as described above, and the main problem is that the joints of both the bonded members are loosened due to shrinkage deformation of the one-side bonded members made of wood over time. It is in the point which provides the member joining structure which can suppress effectively producing | generating, the joining structure of a wooden pillar and a wooden beam, and a joining tool.
本発明の第1特徴構成は、部材接合構造に係り、その特徴は、
少なくとも前端部の外周面を木材に対する螺入操作が可能な木ネジ部としたネジ部が形成された接合用部材が、木材からなる一方側被接合部材に螺着されているとともに、
他方側被接合部材が、前記一方側被接合部材と直接的又は間接的に面接触する配置で前記接合用部材における前記一方側被接合部材との螺着部位よりも後端側の部位に固定手段で固定されており、
前記固定手段が、前記接合用部材の前後中間部に備えられた受け部と、前記接合用部材における前記受け部よりも後端側に備えられ、且つ、前記受け部との間で前記接合用部材に対する前後方向での移動を接当規制する状態で前記他方側被接合部材を挟着可能な押さえ部とから構成されており、
前記受け部と前記押さえ部の両方が、前記接合用部材の外周面に形成された前記ネジ部に対して位置調整可能に螺合されたナットから構成されている点にある。
The first characteristic configuration of the present invention relates to a member joining structure,
A joining member formed with a screw portion in which at least the outer peripheral surface of the front end portion is a wood screw portion that can be screwed into wood is screwed to one side joined member made of wood,
The other side the bonded member, secured to the site of the one side bonded members directly or indirectly rear end side than the threaded portion of the one side bonded members in the connecting member in an arrangement surface contact Fixed by means ,
The fixing means is provided at a rear end side of the receiving portion provided at the front and rear intermediate portion of the joining member and the receiving portion of the joining member, and is used for the joining between the receiving portion and the receiving portion. It is composed of a pressing part capable of sandwiching the other side joined member in a state of restricting the movement in the front-rear direction with respect to the member,
Both the receiving part and the pressing part are constituted by a nut screwed so as to be position-adjustable with respect to the screw part formed on the outer peripheral surface of the joining member .
上記構成によれば、両被接合部材の各々を前記接合用部材の所定部位に別個に固定する形態で両被接合部材を接合するから、木材からなる一方側被接合部材に収縮変形が生じても、接合用部材を介して両被接合部材を相対移動が不能な緩みのない状態(即ち、剛な接合状態)に保つことができる。 According to the above configuration, since both of the members to be joined are joined in a form in which each of the members to be joined is separately fixed to a predetermined portion of the joining member, shrinkage deformation occurs in the one-side joined member made of wood. In addition, both the members to be joined can be kept in a loose state (that is, a rigid joined state) incapable of relative movement via the joining member.
しかも、一方側被接合部材と接合用部材の前端側との螺着部位は、一方側被接合部材の乾燥収縮に伴う締め付け圧力の増大で一層強固になるから、一方側被接合部材の収縮変形に伴い両被接合部材が接触状態から非接触状態になることによる剛性の低下を効率的に補うことができる。 In addition, the screwed portion between the one-side joined member and the front end side of the joining member becomes stronger due to an increase in the tightening pressure accompanying the drying shrinkage of the one-side joined member. Accordingly, it is possible to efficiently compensate for the decrease in rigidity due to the fact that both the joined members are brought into the non-contact state from the contact state.
従って、時間の経過に伴い両被接合部材の接合部に緩みが生じる不具合を効果的に抑止することができる。 Accordingly, it is possible to effectively suppress the problem that the joints of both the joined members are loosened with time.
本構成の実施において、前記固定手段は、前記接合用部材に取り付け可能な別部材等から構成されたものに限らず、溶接部や接着剤による接着部等から構成されていてもよい。 In implementation of this structure, the said fixing means is not restricted to what was comprised from the separate member etc. which can be attached to the said member for joining, You may be comprised from the adhesion part by a welding part, an adhesive agent, etc.
なお、前記木材とは、無垢材等の純粋な木素材のみからなるものに限らず、木素材を含むもの、或いは、集成材や単板積層材、合板、パーティクルボード、ファイバーボード等の種々の木質素材からなるもの等の総称を云う。 The wood is not limited to a pure wood material such as a solid material, but includes a wood material, or a variety of materials such as a laminated material, a single plate laminated material, a plywood, a particle board, and a fiber board. This is a general term for materials made of wood.
また、第1特徴構成では、前記固定手段が、前記接合用部材の前後中間部に備えられた受け部と、前記接合用部材における前記受け部よりも後端側に備えられ、且つ、受け部との間で接合用部材に対する前後方向での移動を接当規制する状態で前記他方側被接合部材を挟着可能な押さえ部とから構成されているから、次の作用効果も奏する。 Further, in the first feature configuration, the fixing means is provided at a rear end side of the receiving member provided at the front and rear intermediate part of the joining member, and the receiving part of the joining member, and the receiving part. because it is configured the other side bonded members in a state of abutment restricting the movement in the longitudinal direction from the clamped possible pressing portion for joining members with the also Kanade following advantages.
つまり、前記受け部と前記押さえ部とによって、接合用部材に対する前後方向での移動が不能な状態で他方側被接合部材を接合用部材に効果的且つ効率的に固定することができる。 That is , the receiving part and the pressing part can effectively and efficiently fix the other-side bonded member to the bonding member in a state in which the movement in the front-rear direction with respect to the bonding member is impossible.
さらに、第1特徴構成では、前記押さえ部と前記受け部の両方が、前記接合用部材の外周面に形成されたネジ部に対して位置調整可能に螺合されたナットから構成されているから、次の作用効果も奏する。 Furthermore, in the first characterizing feature, both the said receiving portion and the pressing portion, and a position adjustable screwed a nut against the threaded portion formed on the outer circumferential surface of the connecting member Therefore, the following effects are also achieved .
つまり、前記接合用部材に対する前後方向において前記押さえ部と前記受け部の両方の位置調整が可能になるから、その位置調整によって一方側被接合部材や他方側被接合部材の厚みの変化に応じた適切な接合状態を現出することができる。 That is, since it is possible to position adjustment of both the receiving part and the pressing part in the front-rear direction with respect to the connecting member, depending on the change in thickness on one side the bonded member and the other side workpieces by the positional adjustment Appropriate bonding state can be obtained.
なお、参考例として、前記受け部が、前記接合用部材の前後中間部に一体形成された受け片部から構成されていることも考えられる。 As a reference example, it is conceivable that the receiving part is constituted by a receiving piece part integrally formed at the front and rear intermediate part of the joining member.
上記構成によれば、例えば、前記受け片部が接合用部材の前後方向に沿って位置移動可能な別部材から構成されている場合に比べ、他方側被接合部材の固定作業の能率化を図ることができるとともに、部材点数を削減することができて、構造の簡素化も図ることができる。 According to the above configuration, for example, as compared with the case where the receiving piece portion is configured from another member that can be moved in the front-rear direction of the bonding member, the fixing work of the other-side bonded member is made more efficient. In addition, the number of members can be reduced, and the structure can be simplified.
また、前記受け片部と前記一方側被接合部材との接当によって一方側被接合部材とネジ部との螺着長さを所定長さに規制することができるから、一方側被接合部材とネジ部との螺着長さを大きく採りすぎることによって他方側被接合部材の固定が不十分になる不具合も防止することができる。 Further, since the screwing length between the one-side joined member and the screw portion can be regulated to a predetermined length by the contact between the receiving piece portion and the one-side joined member, fixed on the other side the bonded members by too take large screwing length of a screw portion can be prevented troubles become insufficient.

本発明の第6特徴構成は、木柱と木梁との接合構造に係り、その特徴は、
前記一方側被接合部材が、木柱から構成されているとともに、
前記他方側被接合部材が、前記木柱と接合される木柱用被接合片部と、木梁と接合される木梁用被接合片部とを備える継手部材から構成され、
前記木柱用被接合片部と前記木柱との接合、及び、前記木梁用被接合片部と前記木梁との接合の一方又は両方に、第1〜第5特徴構成のいずれかに記載の部材接合構造が採用されている点にある。
The sixth characteristic configuration of the present invention relates to a joint structure between a wooden pole and a wooden beam,
While the said one side to-be-joined member is comprised from the wooden pillar,
The other side joined member is composed of a joint member including a wood pole joined piece portion joined to the wooden pole, and a wood beam joined piece portion joined to the wooden beam,
One or both of the joint between the wooden piece to-be-joined piece and the wooden pole, and the joint between the to-be-joined piece for wooden beam and the wooden beam, to any one of the first to fifth characteristic configurations The member joining structure described is employed.
上記構成によれば、前述した部材接合構造によって木構造の架構の剛性を効果的且つ効率的に高めることができ、これにより、木構造の設計の自由度を大幅に高めることができる。 According to the above configuration, the rigidity of the wooden frame can be effectively and efficiently increased by the above-described member joint structure, and thereby the degree of freedom in designing the wooden structure can be greatly increased.
なお、第6特徴構成の実施においては、
前記木柱用被接合片部が前記木柱の周側面部における前記木梁に対向する側の面部に接合され、且つ、前記木梁用被接合片部が木梁の周側面部に接合されるように、木柱用被接合片部と木梁用被接合片部とが直交又は略直交する状態で前記継手部材に備えられ、
前記木柱用被接合片部と前記木柱との接合には、前記部材接合構造が採用されているとともに、

Incidentally, Oite the implementation of the sixth characterizing feature is,
The piece to be joined for wooden pole is joined to a surface portion of the peripheral side surface portion of the wooden pole facing the wood beam, and the piece to be joined for wooden beam is joined to the peripheral side surface portion of the wooden beam. As described above, the joint member is provided in a state in which the to-be-joined piece for wooden pillars and the to-be-joined piece for wooden beams are orthogonal or substantially orthogonal,
While joining the piece to be joined for the wooden pole and the wooden pole, the member joining structure is adopted,
For joining the wood beam to-be-joined piece and the wood beam, the wood beam to-be-joined piece portion is formed on the wood beam to be joined by pressing the wood beam to-be-joined piece to the wood beam with a screw head of a wood screw. A joining structure in which the thread portion of the wood screw is screwed into the wood beam through the inserted hole may be employed.
つまり、前記木柱と前記木柱用被接合片部との接合部では、前記接合用部材の前後方向(つまり、ネジ部の軸心方向)に沿って大きな荷重が作用するために高い接合強度を要するが、前記木梁と前記木梁用被接合片部との接合部では、接合用部材の左右幅方向に沿って大きな荷重が作用することからそれほど高い接合強度を要しない。 That is, since a large load acts along the front-rear direction of the joining member (that is, the axial direction of the screw portion) at the joint between the wooden pole and the piece to be joined for the wooden pole, the joint strength is high. However, since a large load acts along the left-right width direction of the joining member at the joint portion between the wooden beam and the to-be-joined piece portion for the wooden beam, the joint strength is not so high.
このことから、木柱用被接合片部と木柱との接合には前記部材接合構造が採用され、且つ、木梁用被接合片部と木梁との接合には木ネジによる接合構造が採用されている上記構成によれば、剛性の高い木構造の架構を一層効率的に構成することができる。 Therefore, the above-mentioned member joining structure is adopted for joining the wood pole to-be-joined piece and the wood pole, and the joining structure by the wood screw is used for joining the wood beam to-be-joined piece and the wood beam. According to the adopted configuration, a highly rigid wooden structure can be configured more efficiently.

前記固定手段が、前記接合用部材の前後中間部に備えられた受け部と、前記接合用部材における前記受け部よりも後端側に備えられ、且つ、前記受け部との間で前記接合用部材に対する前後方向での移動を接当規制する状態で前記他方側被接合部材を挟着可能な押さえ部とから構成されており、
前記受け部と前記押さえ部の両方が、前記接合用部材の外周面に形成された前記ネジ部に対して位置調整可能に螺合されたナットから構成されている点にある。

Both the receiving part and the pressing part are constituted by a nut screwed so as to be position-adjustable with respect to the screw part formed on the outer peripheral surface of the joining member .
上記構成によれば、時間の経過に伴い両被接合部材の接合に緩みが生じる不具合を効果的に抑止し得る前述の部材接合構造を容易に構成することができる。
また、第7特徴構成では、前記固定手段が、前記接合用部材の前後中間部に備えられた受け部と、前記接合用部材における前記受け部よりも後端側に備えられ、且つ、受け部との間で接合用部材に対する前後方向での移動を接当規制する状態で前記他方側被接合部材を挟着可能な押さえ部とから構成されているから、次の作用効果も奏する。
つまり、前記受け部と前記押さえ部とによって、接合用部材に対する前後方向での移動が不能な状態で他方側被接合部材を接合用部材に効果的且つ効率的に固定することができる。
さらに、第7特徴構成では、前記押さえ部と前記受け部の両方が、前記接合用部材の外周面に形成されたネジ部に対して位置調整可能に螺合されたナットから構成されているから、次の作用効果も奏する。
つまり、前記接合用部材に対する前後方向において前記押さえ部と前記受け部の両方の位置調整が可能になるから、その位置調整によって一方側被接合部材や他方側被接合部材の厚みの変化に応じた適切な接合状態を現出することができる。
According to the said structure, the above-mentioned member joining structure which can suppress effectively the malfunction which loosens in joining of both to-be-joined members with progress of time can be comprised easily.

Furthermore, in the seventh characteristic configuration, both the pressing portion and the receiving portion are configured by nuts screwed so as to be position-adjustable with respect to screw portions formed on the outer peripheral surface of the joining member. The following effects are also exhibited.
In other words, since it is possible to adjust the position of both the pressing portion and the receiving portion in the front-rear direction with respect to the bonding member, the position adjustment corresponds to a change in the thickness of the one-side bonded member or the other-side bonded member. Appropriate bonding state can be revealed.
