Description
本発明は、木造建築等の木構造における木質部材の接合構造に関する。 The present invention relates to a joining structure of wooden members in a wooden structure such as a wooden building.
従来、住宅等の木造建築では軸組構法が採用され、梁や柱等の木質部材同士の仕口において、ほぞやほぞ穴を形成するほぞ差しや、アングル等の接合金具を利用した木組みによる接合が行われている。
しかし、法に則り自由な木造建築を実現するためには、木造建築においても、構造計算が可能であり、耐震性能を明確に評価することができる構造が必要である。従って、自由な木造建築を実現するための手段の一つとして、多様な用途に対応することができ、且つ、構造計算にて構造的な安全性を確認することが可能なラーメン構造を実現することが挙げられる。躯体を柱と梁の接合性の抵抗力だけで持ちこたえるラーメン構造では、剛性の高い接合部の接合構造が必要であり、従って、木造ラーメン構造では、継手・仕口など接合部の設計の良否が架構の安全性・経済性・構造デザインを決定する要因となる。
Traditionally, wooden frames have been used in wooden structures such as houses, and in joints made of wooden members such as beams and columns, mortises that form mortises and mortises, and joints using wooden structures using joints such as angles Has been done.
However, in order to realize free wooden construction in accordance with the law, structural construction is also possible in wooden construction, and a structure that can clearly evaluate seismic performance is required. Therefore, as one of the means for realizing free wooden construction, a ramen structure that can be used for various purposes and can confirm structural safety by structural calculation is realized. Can be mentioned. In the case of a rigid frame structure in which the frame is held only by the resistance of the connection between the column and the beam, it is necessary to have a highly rigid joint structure. Therefore, in the case of a wooden frame structure, the joint design such as joints and joints is good or bad. Is a factor that determines the safety, economic efficiency and structural design of the frame.
木造ラーメン構造を実現するための木質部材の接合構造として、柱・梁の接合部に孔を穿設して異形鉄筋を挿入し、接着剤の充填・硬化によって木質部材同士を剛接合するという特徴を有する構造が提案されている。例えば、特許文献１又は特許文献２に記載の技術である。 As a structure for joining wooden members to realize a wooden frame structure, a feature is that holes are made in the column / beam joints, deformed reinforcing bars are inserted, and the wooden members are rigidly joined together by filling and hardening the adhesive. A structure having For example, the technique described in Patent Document 1 or Patent Document 2.
特許文献１では、接合しようとする木質部材における一方又は双方の部材に穿設した鉄筋挿入穴（又は貫通している挿入孔）に予め接着剤を装填しておき、前記木質部材の組み立て時に接合用鉄筋を鉄筋挿入孔に嵌入して穴内の接着剤を鉄筋外周と穴内周との間の空隙部に充填し、硬化させる木質部材の接合構造が公開されている。 In Patent Document 1, an adhesive is loaded in advance into a reinforcing bar insertion hole (or an insertion hole penetrating through) one or both of the wood members to be joined, and joined when the wood member is assembled. A wood member joining structure is disclosed in which a reinforcing bar is inserted into a reinforcing bar insertion hole, an adhesive in the hole is filled in a gap between the outer periphery of the reinforcing bar and the inner periphery of the hole, and cured.
また、特許文献２では、接合すべき木質部材のうち、一方の部材には材軸方向に延び、端部が同一の部材の接合端に開放するボルト埋め込み穴を設け、他方の部材には前記一方の部材の材軸の延長方向に延びるボルト貫通孔を設け、該ボルト貫通孔及び前記ボルト埋め込み穴にわたってボルトを挿入するとともに、前記ボルトと穴（孔）の内周面との間隙に接着剤を装填、硬化させる木質部材の接合構造が公開されている。 Further, in Patent Document 2, one of the wood members to be joined is provided with a bolt embedding hole that extends in the material axis direction and has an end opened to the joining end of the same member, and the other member has the above-mentioned A bolt through-hole extending in the direction of extension of the material shaft of one member is provided, a bolt is inserted through the bolt through-hole and the bolt embedding hole, and an adhesive is provided in a gap between the bolt and the inner peripheral surface of the hole (hole). The connection structure of the wooden member which loads and hardens is disclosed.
上記従来技術では、従来の軸組構法と比較して、接着剤で強固に部材間を固定するため、高耐力が得られ、耐力壁や筋交いを必要としない木質ラーメン構造が可能とされている。また、従来の接合金具を用いた構法のように仕口部や継手部に接合金具が露出せず、さらに、柱・梁の継手・仕口部であれば接合位置に制約がないため、デザイン性に優れ、火災時の構造耐力低下を防止ししている。 Compared to the conventional frame construction method, the above-mentioned conventional technology firmly fixes the members with an adhesive, so that a high yield strength is obtained, and a wooden ramen structure that does not require a bearing wall or bracing is possible. . Also, unlike conventional construction methods using joint fittings, the joint fittings are not exposed at the joints and joints, and there are no restrictions on the joint positions for column / beam joints / joints. It has excellent properties and prevents a decrease in structural strength during a fire.
しかし、上記従来技術において、接合しようとする木質部材同士に鉄筋等の連続する挿通部材を挿通させるわけであるが、挿通部材の挿通されている部分において局部的にいずれか片方の木質部材が他方の木質部材に局部的にめり込むことがあり、この場合、接合部にずれやゆるみが生じて、接合の強度や精度の低下を招く恐れがあるという不具合がある。 However, in the above-described prior art, a continuous insertion member such as a reinforcing bar is inserted between the wooden members to be joined, but either one of the wooden members is locally in the portion where the insertion member is inserted. There is a problem that the wood member is locally sunk, and in this case, the joining portion is displaced or loosened, which may cause a reduction in joining strength or accuracy.

但し、本発明に係る木質部材の接合構造の適応される接合部１０は、梁Ａと柱Ｂとの接合部１０に限定されるものではなく、柱同士、又は、梁同士とすることもできる。
1 and 2, A is a beam as the wooden member 11, and B is a pillar as the wooden member 11. In the same figure, the joining structure of the wooden members 11 and 11 according to the present invention will be described using the joining portion 10 between the column B and the beam A. FIG.
However, the joining part 10 to which the joining structure of the wooden members according to the present invention is applied is not limited to the joining part 10 between the beam A and the column B, and may be between the columns or between the beams. .
接合する木質部材１１・１１の接合部分にはそれぞれにおいて挿通部１１ｂ・１１ｂと板嵌合部１１ｃ・１１ｃとが形成されている。
挿通部１１ｂは、木質部材１１・１１同士を接合するための挿通部材１４を挿入するための穴（若しくは孔）であって、接合面１１ａに向けて開口している。従って、挿通部１１ｂの深さや断面形状や断面積は、挿通部材１４の長さや断面形状や断面積等に応じて適当なものとすることが好ましい。
また、板嵌合部１１ｃは、図３に示す如く、木質部材１１の接合面１１ａに形成された凹部であり、板状部材１３が嵌合可能な形状とされている。板嵌合部１１ｃは、接合する木質部材１１の間に介装される板状部材１３が外部に露出することのないようにするための構造であり、木質部材１１の接合面１１ａよりも一回り小さな形状でとされている。但し、板嵌合部１１ｃは接合部１０の形状によっては、接合する木質部材１１・１１のうちいずれか一方に形成したり、或いは、全く形成しない形態を採ったりすることもできる。
Insertion portions 11b and 11b and plate fitting portions 11c and 11c are formed at the joining portions of the wood members 11 and 11 to be joined.
The insertion part 11b is a hole (or hole) for inserting the insertion member 14 for joining the wooden members 11, 11, and opens toward the joining surface 11a. Therefore, it is preferable that the depth, the cross-sectional shape, and the cross-sectional area of the insertion portion 11 b are appropriate according to the length, the cross-sectional shape, the cross-sectional area, and the like of the insertion member 14.
Moreover, the board fitting part 11c is a recessed part formed in the joining surface 11a of the wooden member 11, as shown in FIG. 3, and is made into the shape which the plate-shaped member 13 can fit. The plate fitting portion 11 c is a structure for preventing the plate-like member 13 interposed between the wood members 11 to be joined from being exposed to the outside, and is one more than the joint surface 11 a of the wood member 11. It is said to have a small shape around. However, depending on the shape of the joint portion 10, the plate fitting portion 11c may be formed on one of the wood members 11 and 11 to be joined, or may take a form that is not formed at all.
図４に示す如く、接合する木質部材１１・１１の接合面１１ａ・１１ａに形成された板嵌合部１１ｃ・１１ｃに嵌設される板状部材１３は、木質部材１１の接合面１１ａの面積よりも一回り小さい形状であって、挿通部材１４を挿通させるための挿通部１３ｂが形成されている。挿通部１３ｂは、挿通部材１４が遊挿可能な孔であって、木質部材１１に形成された挿通部１１ｂ・１１ｂ・・・の位置に合わせて、適宜数設けられている。

なお、図５及び図６に示す如く、板状部材１３に形成される挿通部１３ｂの外周に突縁部１３ａを形成することもできる。この場合、挿通部材１４の、接合する木質部材１１・１１の間に位置する部分に発生する応力の集中を回避することができ、挿通部材１４の折れや曲がり等の破損を防止することができる。
As shown in FIG. 4, the plate-like member 13 fitted in the plate fitting portions 11 c and 11 c formed on the joint surfaces 11 a and 11 a of the wood members 11 and 11 to be joined is an area of the joint surface 11 a of the wood member 11. An insertion portion 13b for inserting the insertion member 14 is formed. The insertion part 13b is a hole in which the insertion member 14 can be loosely inserted, and a suitable number of insertion parts 13b are provided according to the positions of the insertion parts 11b, 11b,.
In the present embodiment, a steel plate is employed as the plate member 13. However, the plate-like member 13 is not limited to a steel plate, and other materials such as a resin material can be adopted.
In addition, as shown in FIG.5 and FIG.6, the protrusion part 13a can also be formed in the outer periphery of the insertion part 13b formed in the plate-shaped member 13. FIG. In this case, concentration of stress generated in the portion of the insertion member 14 located between the wood members 11 and 11 to be joined can be avoided, and breakage such as bending and bending of the insertion member 14 can be prevented. .
前記挿通部材１４は、接合する木質部材１１・１１のそれぞれにおいて形成された挿通部１１ｂ・１１ｂに一直線上に連続して架設されることによって、木質部材１１・１１を接合するためのものである。
本実施例では挿通部材１４として鉄筋が採用されている。なお、鉄筋は、後述する接着剤の塗布面積が大きくなるように異形鉄筋であることが好ましいが、丸型鉄筋や角形鉄筋等を採用することもできる。
The insertion member 14 is used to join the wood members 11 and 11 by being continuously installed in a straight line on the insertion portions 11b and 11b formed in the wood members 11 and 11 to be joined. .
In this embodiment, a reinforcing bar is used as the insertion member 14. In addition, although it is preferable that a reinforcing bar is a deformed reinforcing bar so that the application area | region of the adhesive agent mentioned later may become large, a round reinforcing bar, a square reinforcing bar, etc. can also be employ | adopted.
そして、木質部材１１・１１を接合する際には、まず、接合する木質部材１１・１１のそれぞれに形成した挿通部１１ｂ・１１ｂの両方に接着剤１５・１５を装填し、続いて、接合しようとする一方の木質部材１１の接合面１１ａに形成された板嵌合部１１ｃに板状部材１３を嵌合させる。最後に、接合しようとする一方の木質部材１１の挿通部１１ｂと、板状部材１３の挿通部１３ｂと、接合しようとする他方の木質部材１１の挿通部１１ｂに、連続する一本の挿通部材１４を挿通させる。このとき、挿通部材１４はその一側端部より順に、接合しようとする一方の木質部材１１の挿通部１１ｂと、板状部材１３の挿通部１３ｂと、接合しようとする他方の木質部材１１の挿通部１１ｂとに、挿入されていることとなる。そして、時間の経過に伴って、挿通部１１ｂの内周と、挿通部材１４の外周との間隙に存在する接着剤によってこれらが接着固定されて、木質部材１１・１１が接合される。 When joining the wood members 11 and 11, first, the adhesives 15 and 15 are loaded into both the insertion portions 11b and 11b formed in the wood members 11 and 11 to be joined, and then joined. The plate-like member 13 is fitted to the plate fitting portion 11c formed on the joint surface 11a of the one wooden member 11. Finally, one insertion member continuous to the insertion portion 11b of the one wooden member 11 to be joined, the insertion portion 13b of the plate-like member 13, and the insertion portion 11b of the other wooden member 11 to be joined. 14 is inserted. At this time, the insertion member 14 has an insertion portion 11b of one wooden member 11 to be joined, an insertion portion 13b of the plate-like member 13 and an insertion portion 13b of the other wooden member 11 to be joined. It will be inserted in the insertion part 11b. Then, as time elapses, these members are bonded and fixed by an adhesive existing in the gap between the inner periphery of the insertion portion 11b and the outer periphery of the insertion member 14, and the wood members 11 and 11 are joined.
上述の接合工程により接合される木質部材の接合構造では、接合する木質部材１１・１１の間に板状部材１３が介装され、木質部材１１・１１と板状部材１３とに形成された挿通部１１ｂ・１１ｂ・１３ｂに、連続する挿通部材１４が挿通され、挿通部材１４と木質部材１１・１１とが接着剤１５により接着固定されている。
なお、挿通部材１４の本数は、単数本とすることも、複数本とすることもでき、接合する木質部材１１・１１の接合面１１ａ・１１ａの面積や、木質部材１１・１１の重さや規模等に応じて調整することが好ましい。
In the joining structure of the wood members joined by the joining process described above, the plate-like member 13 is interposed between the wood members 11 and 11 to be joined, and the wood member 11 · 11 and the plate-like member 13 are inserted. The continuous insertion member 14 is inserted into the portions 11 b, 11 b, and 13 b, and the insertion member 14 and the wooden members 11 and 11 are bonded and fixed by the adhesive 15.
The number of the insertion members 14 may be singular or plural, and the area of the joining surfaces 11a and 11a of the wood members 11 and 11 to be joined, and the weight and scale of the wood members 11 and 11 It is preferable to adjust according to the above.
上述の木質部材の接合構造においては、木質部材１１・１１を接合するために使用される板状部材１３や挿通部材１４という接合する木質部材１１・１１以外の部材が外部に露出することがなく、すなわち、本接合構造により組み立てられた木造建築の躯体において柱梁の外側に金具といった接合具等が露出しないため、木質感を損なわず、また、接合具の錆びや結露等の恐れがないため接合部１０に高い耐久性を備えることができる。そして、根太・梁・柱といった躯体そのものを空間の内装として利用することができ、デザイン性の高い内装空間を演出することができる。さらに、そのデザイン性と耐久性の優位さから、ゲートなどの外構として、本発明に係る接合構造を採用した木質部材を採用することができる。このように、美観上の木質感を損なわないことから、伝統木造志向の顧客にも受け入れられることが期待できる。 In the wood member joining structure described above, members other than the wood members 11 and 11 to be joined such as the plate-like member 13 and the insertion member 14 used for joining the wood members 11 and 11 are not exposed to the outside. In other words, because the joints such as metal fittings are not exposed to the outside of the column beam in the frame of the wooden building assembled with this joint structure, the wood texture is not impaired, and there is no fear of rust or condensation on the joints. The joining portion 10 can be provided with high durability. And the frame itself such as joists, beams and pillars can be used as the interior of the space, and an interior space with high design can be produced. Furthermore, the wooden member which employ | adopted the joining structure which concerns on this invention as an outer structure, such as a gate, can be employ | adopted from the superiority of the design property and durability. In this way, since it does not impair the aesthetic wood texture, it can be expected to be accepted by traditional wooden-oriented customers.
また、接合する木質部材１１・１１の外部に露出するものがないため、例えば、木質部材１１としての梁Ａと、木質部材１１としての柱Ｂとを接合して、木造建築の枠組みを形成する場合、柱際までサッシが取り付けられる等、開口幅そのままを利用することができ大開口を実現することができる。
さらに、木造建築の躯体を構成する際に、高精度なほぞやほぞ穴の加工をする必要がないため、従来の軸組工法と比較して施工の手間が小さく、釘やピンを打つ騒音も少ない。そして、接着剤を使用することにより、接合金具等の接合具を用いるときに発生する接合具と木質部材との滑りがなく、木質部材同士の接合部にラーメン構造を採るために十分な高い剛性を得ることができる。
Moreover, since there is nothing exposed outside the wooden members 11 and 11 to be joined, for example, a beam A as the wooden member 11 and a pillar B as the wooden member 11 are joined to form a framework of a wooden building. In this case, the opening width can be used as it is, for example, a sash is attached to the edge of the pillar, and a large opening can be realized.
Furthermore, since it is not necessary to machine mortise and mortise holes with high precision when constructing a wooden structure, the construction work is less than that of the conventional shaft assembly method, and the noise of hitting nails and pins is also reduced. Few. And, by using an adhesive, there is no slip between the joint and the wooden member that occurs when using a joint such as a joint fitting, and high rigidity sufficient to adopt a ramen structure at the joint between the wooden members Can be obtained.
そして、接合する木質部材１１・１１間に板状部材１３が介装されることによって、一方の木質部材１１への他方の木質部材１１のめり込みが軽減される。従って、接合部１０におけるずれやゆるみが抑止され、接合部１０の剛性と耐久性を高めることができる。 And the plate-like member 13 is interposed between the wood members 11 and 11 to be joined, so that the penetration of the other wood member 11 into the one wood member 11 is reduced. Accordingly, displacement and loosening at the joint 10 are suppressed, and the rigidity and durability of the joint 10 can be enhanced.
そして、本発明に係る接合構造では、特に本実施例においては、挿通部材１４としての異形鉄筋と、板状部材１３としての鋼板とで、木質部材１１・１１を接合することができ、特殊な材料を用いることなく、接合構造を構成している。従って、接合構造に必要となる構成部材を容易に調達することができ、また、汎用部材を利用することができるので、接合構造にかかるコストを抑制することができる。 And in the joining structure which concerns on this invention, especially in a present Example, the wooden members 11 * 11 can be joined with the deformed reinforcing bar as the insertion member 14, and the steel plate as the plate-like member 13, and it is special. The joining structure is configured without using any material. Therefore, constituent members required for the joining structure can be easily procured, and since a general-purpose member can be used, the cost for the joining structure can be suppressed.
なお、図７に示す如く、前記挿通部材１４として鋼板１４Ｂを採用することもできる。
この場合、接合する木質部材１１には鋼板１４Ｂを挿入可能な溝を形成し、同様に、板状部材１３にも鋼板を挿入可能な溝１３ｄを形成する。このように、挿通部材１４として鋼板１４Ｂを採用するときは、挿通部材１４と木質部材１１とが接着剤１５にて接合される面積が、挿通部材１４として鉄筋１４Ａを採用するときと比較して大きくなるため、強固に接合されることになる。
As shown in FIG. 7, a steel plate 14B can be adopted as the insertion member 14.
In this case, a groove into which the steel plate 14B can be inserted is formed in the wood member 11 to be joined, and similarly, a groove 13d into which the steel plate can be inserted is also formed in the plate member 13. As described above, when the steel plate 14B is employed as the insertion member 14, the area where the insertion member 14 and the wood member 11 are joined by the adhesive 15 is larger than when the reinforcing bar 14A is employed as the insertion member 14. Since it becomes large, it will join firmly.
また、躯体において柱勝ちになる接合部等の、他と比較して接合部に発生する剪断力が大きくなる場所には、鋼管１４Ｃを挿通部材１４として、挿通部材１４としての異形鉄筋１４Ａと同様に適宜補助用に挿入することができる。
図８に示す如く、挿通部材１４として異形鉄筋１４Ａに加え、挿通部材１４として鋼管１４Ｃを採用し、すなわち、一つの接合部１０において、挿通部材１４として、異形鉄筋１４Ａと鋼管１４Ｃとを併用する接合構造としている。これにより、曲げ荷重に対して異形鉄筋１４Ａが優位に作用し、剪断力に対して鋼管１４Ｃが優位に作用するため、挿通部材１４が異形鉄筋１４Ａのみである場合と比較して大幅に剪断力に対して強い接合部１０とすることができる。そして、挿通部材１４としての異形鉄筋１４Ａのみで同程度の剛性を得ようとするときと比較して、接合構造をコンパクトに構成することができ、これにより接合部１０の設計が容易となる。
In addition, the steel pipe 14C is used as the insertion member 14 and the deformed reinforcing bar 14A as the insertion member 14 at a place where the shearing force generated at the joint is greater than others, such as the joint where the column wins in the frame. It can be inserted as an auxiliary as appropriate.
As shown in FIG. 8, in addition to the deformed rebar 14A as the insertion member 14, a steel pipe 14C is adopted as the insertion member 14, that is, the deformed rebar 14A and the steel pipe 14C are used together as the insertion member 14 in one joint portion 10. It is a junction structure. As a result, the deformed reinforcing bar 14A acts preferentially with respect to the bending load, and the steel pipe 14C acts preferentially with respect to the shearing force. Therefore, the shearing force is greatly increased as compared with the case where the insertion member 14 is only the deformed reinforcing bar 14A. It can be set as the joint part 10 strong with respect to. And compared with the case where it is going to acquire comparable rigidity only by the deformed reinforcing bar 14A as the penetration member 14, a joining structure can be comprised compactly, and, thereby, design of the junction part 10 becomes easy.
さらに、図９に示す、梁Ａ−柱Ｂ−梁Ａの接合部１０、柱Ｂ−柱Ｂの接合部１０のように、木造建築の躯体を構成する木質部材１１の接合部１０の全てにおいて、本発明に係る接合構造を適応させることができる。
これにより、木造建築におい二次元ラーメン構造を採用することができ、架構された躯体は水平力を負担できるため、面材や筋交いによる耐力壁が不要となる。
Further, in all of the joint portions 10 of the wooden members 11 constituting the frame of the wooden building, such as the joint portion 10 of the beam A-column B-beam A and the joint portion 10 of the column B-column B shown in FIG. The joining structure according to the present invention can be adapted.
As a result, a two-dimensional frame structure can be employed in a wooden building, and the framed frame can bear a horizontal force, so that a bearing wall made of face material or braces becomes unnecessary.
