Description

本発明は、木材同士、すなわち木造建築物における縦材である柱と、横材である土台等の下部横架材、或いは梁または桁等の上部横架材とを緊結固定する木造建築物における木材同士の結合構造及びその方法に関するものである。   The present invention relates to a wooden building in which woods, that is, columns that are vertical members in a wooden building, and a lower horizontal member such as a base that is a horizontal member, or an upper horizontal member such as a beam or a girder, are fixed. The present invention relates to a connection structure between woods and a method therefor.

木造建築物において、土台や梁などの横架材と柱とを緊結する手段として、柱側面に接合金物を設置し、横架材と接合金物をボルトによって接合し、接合金物と柱脚柱頭を各種接合具によって接合する方法、例えば下記特許文献1に示されるような接合具、所謂ホールダウン金物等による接合方法がある。   In a wooden building, as a means to bind the horizontal members such as bases and beams to the columns, joints are installed on the side surfaces of the columns, and the horizontal members and the joints are joined by bolts. There is a joining method using various joining tools, for example, a joining method as shown in Patent Literature 1 below, a joining method using a so-called hole-down hardware or the like.

しかし、接合金物を柱側面に設置する方法は、接合金物及び接合具の露出を免れず、筋交い金物等の他の金物との干渉や、窓枠部での施工不具合等の問題がある。   However, the method of installing the metal joint on the side of the column is inevitable from exposing the metal joint and the joint, and has problems such as interference with other metal hardware such as a bracing metal and a construction defect in a window frame portion.

そこで、下記特許文献2に示すほぞパイプ型の接合金物や、下記特許文献3に示す鋼板挿入型の接合金物によって、柱脚柱頭を接合固定する方法がある。   Therefore, there is a method of joining and fixing the column capital by means of a tenon-type joint metal fitting shown in Patent Literature 2 and a steel plate insertion type metal fitting shown in Patent Literature 3 below.

これらの接合金物によれば、柱内に挿通されるため、施工後に柱側面に金物類が突出せず、柱側面を面一となすことができるので、美観に優れ、化粧仕上げを施すにも都合がよい。

しかし、これら先行技術の構造は、金属製であることから壁体内の熱橋となり、壁体内結露を引き起こす可能性を有するという問題がある。また、金物類の原材料及び加工コストが高いという問題もある。   However, these prior art structures have a problem in that since they are made of metal, they become a thermal bridge in the wall and may cause dew condensation in the wall. There is also a problem that the raw materials and processing costs of hardware are high.

そこで、ほぞパイプ型の接合金物と同様に、柱木口及び横架材面に木ダボを挿通することで柱脚柱頭を接合する方法がある。   Therefore, there is a method of joining the column capitals by inserting a wooden dowel into the mouth of the pillar and the side of the cross member, as in the case of the tenon-type joint metal fitting.

しかし、これらを施工する際は、あらかじめ柱木口や土台に対する加工を要し、施工途中または施工後の追加変更が困難であるという問題があり、特に既存建物に対しての補強工事などは、大がかりな工事を伴い、非常に煩雑である。   However, when constructing these, there is a problem that it is necessary to process in advance the pillar pier and base, and it is difficult to make additional changes during or after construction, especially for reinforcement work on existing buildings, etc. It is very complicated with complicated construction.

そこで本発明は、上記問題点を解消するために、新築建物に加えて既存建物の補強が大がかりな工事をすることなく容易に縦材と横材など木材同士の接合部における補強構造を得ることを可能とするとともに、接合金具などが表出せず美観に優れ、環境に優しい木材を用いた木造建築物における木材同士の結合構造及びその方法を提供することを目的としている。   In order to solve the above-mentioned problems, the present invention is to easily obtain a reinforcing structure at a joint portion between timbers such as a vertical member and a horizontal member without performing large-scale construction of an existing building in addition to a new building. It is an object of the present invention to provide a joint structure between woods in a wooden building using environmentally friendly wood, which is excellent in aesthetic appearance without showing a joint fitting and the like, and a method therefor.

次に、上記の課題を解決するための手段を、実施の形態に対応する図面を参照して説明する。
この発明の請求項1記載の木造建築物における木材同士の結合構造は、木材a,b同士の接合部における互いの接合面に対し前記両木材a,bにわたって斜め方向に連通するダボ孔1が穿設され、該ダボ孔1に木ダボdを挿入してなることを特徴とする。
Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.
In the wooden structure according to the first aspect of the present invention, the dowel hole 1 communicating obliquely across the two lumbers a and b with respect to the joint surface at the joint between the lumbers a and b is provided. It is formed by inserting a wooden dowel d into the dowel hole 1.

また、請求項2記載の木造建築物における木材同士の結合構造は、木材a,b同士の接合部における互いの接合面に対し前記両木材a,bにわたって斜め方向に連通するダボ孔1が穿設され、該ダボ孔1に接着剤fとともに木ダボdを挿入してなることを特徴とする。   Further, in the connecting structure of the timbers in the wooden building according to the second aspect, the dowel hole 1 is formed so that the dowel hole 1 that communicates in an oblique direction across the two timbers a and b with respect to the joining surface at the joining portion of the timbers a and b. And a wooden dowel d is inserted into the dowel hole 1 together with the adhesive f.

請求項3記載の木造建築物における木材同士の結合方法は、木材a,b同士の接合部における互いの接合面に対し前記両木材a,bにわたって連通するダボ孔1を斜め方向に穿設する工程と、
前記ダボ孔1内に接着剤fを注入する工程と、
木ダボdに接着剤fを塗布する工程と、
前記ダボ孔1内に前記木ダボdを挿入する工程と、
を有することを特徴とする。
According to a third aspect of the present invention, there is provided a method for joining timber in a wooden building, wherein a dowel hole 1 communicating with both of the woods a and b is formed obliquely with respect to a joint surface of a joint between the woods a and b. Process and
Injecting an adhesive f into the dowel hole 1;
A step of applying an adhesive f to the wooden dowel d;
Inserting the wooden dowel d into the dowel hole 1;
It is characterized by having.

このような木造建築物における木材同士の結合構造及びその方法によれば、木造建築物の木材としての縦材である柱bと、木材としての横材である土台aや梁または桁等の下部横架材、或いは梁または桁等の上部横架材a’との接合部、すなわち柱脚部や柱頭部を斜めに連通されるダボ孔1に挿入される木ダボdにて補強を行うことが可能であり、このことから、新築建物に加えて、既存建物の柱脚部及び柱頭部の補強が大がかりな工事をすることなく容易に行えるようになる。   According to such a connection structure between timbers in a wooden building and a method therefor, a pillar b as a timber as a timber of a wooden building and a base a, a beam or a girder as a timber as a timber. Reinforcement with a horizontal member or a joint with an upper horizontal member a ′ such as a beam or a girder, that is, a wooden dowel d that is inserted into a dowel hole 1 that diagonally connects a column base or a column cap. This makes it possible to easily reinforce the column bases and capitals of an existing building in addition to a newly-built building without performing large-scale construction.

また、ダボ孔1に木ダボdを挿入させる際に接着剤fとともに挿入する構造とすることで、木材a,b同士は互いの結合強度を高めることとなる。   Further, when the wooden dowel d is inserted into the dowel hole 1, the structure is such that the wooden a and b are inserted together with the adhesive f, thereby increasing the bonding strength between the wood a and b.

なお、ダボ孔1の穿設数は、複数としても良く、例えば、X字状に側方視で交差するように2カ所としても良い。また、木材a,b同士の接合部としては、ほぞ3とほぞ孔2とで構成されるほぞつぎ構造としてもよい。このほぞつぎ構造の場合には、ほぞ3とほぞ孔2との対向当接面に沿って連通するダボ孔1として穿設されることとする構造が好ましく、このような構造によれば、ダボ孔1内に接着剤fを注入する際に、ほぞ3とほぞ孔2との対向当接面間にも接着剤fが浸入し、結合構造として、その結合強度がさらに向上することとなる。   The number of the dowel holes 1 may be plural, and may be two, for example, so as to intersect in an X-shape in a side view. The joint between the woods a and b may have a tenon structure including a tenon 3 and a tenon hole 2. In the case of this tenon structure, it is preferable that the dowel hole 1 is formed as a dowel hole 1 communicating along the abutting contact surface between the tenon 3 and the tenon hole 2. When the adhesive f is injected into the hole 1, the adhesive f also penetrates between the facing contact surfaces of the tenon 3 and the tenon 2, and the bonding strength is further improved as a bonding structure.

本発明の木造建築物における木材同士の結合構造及びその方法によれば、木ダボは木材同士を相互に連通するダボ孔に斜めに挿通され、外部に突出することがないことから、美観に優れ、化粧仕上げを施すにも都合が良い効果を得られる。また、木ダボは、各木材と同等の素材とされることから、従来のような熱橋となって起こる結露などが発生するおそれがない。さらに、木ダボの配置される方向が、木材同士の結合方向に対して斜め方向とされることで、木材同士の接合部分における曲げ方向及び引抜き方向にこの木ダボが抵抗力を発揮することができる。そしてこの木ダボによれば、木材同士、例えば土台と柱となじみやすく、この接合部における従来のような金属製ボルトや鋼棒など剛性の高い部材を用いることによる割裂破壊を起こしにくくなるという効果を得ることができる。   ADVANTAGE OF THE INVENTION According to the connection structure of the wood in the wooden building of this invention, and the method, the wood dowel is inserted obliquely into the dowel hole which connects woods mutually, and does not protrude outside, and is excellent in aesthetics. In addition, a favorable effect can be obtained in applying a cosmetic finish. Further, since the wood dowel is made of the same material as each wood, there is no possibility that dew condensation or the like occurring as a conventional thermal bridge occurs. Furthermore, since the direction in which the wooden dowels are arranged is oblique to the direction in which the wooden pieces are joined, the wooden dowels can exhibit resistance in the bending direction and the pull-out direction at the joint between the wooden pieces. it can. According to this wooden dowel, it is easy to fit between the woods, for example, the base and the column, and it is difficult to cause splitting fracture by using a rigid member such as a conventional metal bolt or steel bar at this joint. Can be obtained.

特に、本発明の木造建築物における木材同士の結合構造及びその方法によれば、木材としての柱などの縦材及び横架材などの横材の設置後の加工が可能であるため、新築建物の施工途中での柱脚部及び柱頭部の緊結はもちろん、施工後の緊結、さらには、既存建物の柱脚部及び柱頭部の補強、伝統建物の下屋部での柱脚部及び柱頭部の補強を、大がかりな工事をすることなく容易に行えるという利点がある。   In particular, according to the joint structure and method of the timber in the wooden building of the present invention, the post-installation processing of the vertical members such as pillars and the horizontal members such as the horizontal members as the timber is possible. Tightening of pillars and capitals during construction, as well as binding after construction, further reinforcement of pillars and capitals of existing buildings, pillars and capitals in lower buildings of traditional buildings There is an advantage that the reinforcement can be easily performed without extensive construction.

また、ダボ孔と木ダボとに接着剤を用いることで、木材同士の互いの結合状態が、より強固なものとなり、斜めに挿入される木ダボとともに、十分な強度を得ることのできる結合構造となる。   Also, by using an adhesive for the dowel hole and the wood dowel, the bonding state of the woods becomes stronger, and together with the wood dowel inserted diagonally, a bonding structure capable of obtaining sufficient strength. It becomes.

図1は本発明による木造建築物における木材としての縦材と横材との結合構造の一実施の形態を示す斜視図を(a)、透過斜視図を(b)に示した説明図である。
なお、以下に説明する実施の形態において、木造建築物における木材としては、一方が横材、他方が縦材として説明し、横材としては基礎上に設置される土台a、縦材としては柱bとし、これら土台aと柱bから成る柱脚接合部における結合構造として説明する。
FIG. 1 is an explanatory view showing a perspective view and a transparent perspective view showing one embodiment of a combined structure of a vertical member and a horizontal member as wood in a wooden building according to the present invention. .
In the embodiment described below, as wood in a wooden building, one is described as a horizontal member, and the other is described as a vertical member. The horizontal member is a base a installed on a foundation, and the vertical member is a pillar. b, and will be described as a connection structure at a column-base joint portion composed of the base a and the column b.

土台aと柱bとは、ほぞ3及びほぞ孔2が形成され、これらほぞ3及びほぞ孔2にて互いが接合される。これら土台aと柱bとにわたり、ほぞ3及びほぞ孔2に干渉しない位置にダボ孔1が穿設される(図2参照)。
このダボ孔1は、柱bの側面から斜め方向に、土台aに達しており、すなわち柱bと土台aとにわたってダボ孔1が連通して形成される。
The mortise 3 and the mortise hole 2 are formed between the base a and the pillar b, and the mortise 3 and the mortise hole 2 are joined to each other. A dowel hole 1 is formed at a position that does not interfere with the tenon 3 and the tenon 2 over the base a and the column b (see FIG. 2).
The dowel hole 1 reaches the base a in an oblique direction from the side surface of the column b, that is, the dowel hole 1 is formed to communicate with the column b and the base a.

本実施の形態では、図1(b)及び図5,6に示すように、側方視で、略X字状となって交差するように、平面視で互い違いとなるように、ほぞ3を挟んでそれぞれ位置し、2カ所のダボ孔1が形成される。
そして、このダボ孔1には、接着剤が注入され、木ダボdが挿入される。
In the present embodiment, as shown in FIG. 1B and FIGS. 5 and 6, the tenon 3 is so arranged as to be substantially X-shaped and cross each other in a side view, and alternately in a plan view. Two dowel holes 1 are formed so as to be sandwiched between them.
Then, an adhesive is injected into the dowel hole 1, and a wooden dowel d is inserted.

すなわち、柱bを貫通して、図1(b)に示すように、木ダボdの先端側略半部が土台aに挿入され、互いを結合状態としている。この結合状態では、図1(a)に示すように、柱bの側面に木ダボdの端部のみが表出する。
なお、この木ダボdの端部は、柱b側面より突出状態で挿入を終えて柱bの側面に沿って削り落とすか、柱bの側面よりもさらに挿入を行い、側面に対して凹状となるダボ孔1の開口部分に木栓やパテ埋めなどの処理を施して側面を平滑に形成することとしても良い。
That is, as shown in FIG. 1 (b), approximately half of the dowel d is inserted into the base a so as to penetrate the column b, and the wooden dowel d is connected to each other. In this connected state, as shown in FIG. 1 (a), only the end of the wooden dowel d is exposed on the side surface of the pillar b.
In addition, the end of the dowel dowel d is inserted in a state protruding from the side surface of the column b and is shaved off along the side surface of the column b, or is inserted further than the side surface of the column b, and is concave with respect to the side surface. The opening portion of the dowel hole 1 may be subjected to processing such as wood plug or putty to form a smooth side surface.

次に、上記構成の施工手順について説明する。
まず、木造建築物の基礎上に設置された土台a及び柱bより成る柱脚接合部において、本実施の形態では、図2に示すような、穿孔装置cを用いて、柱b側面より、柱bに対して所定の角度、例えば柱の略垂直な側面から約30°の角度で、土台a及び柱bを相互に連通するダボ孔1を設ける。なお、このダボ孔1は、土台aを貫通しない程度の長さが好ましい。すなわちダボ孔1が貫通しないことで、後述する接着剤注入時に、接着剤が土台a内に留まることとなる。
Next, a construction procedure of the above configuration will be described.
First, in the column-base joint portion composed of the base a and the column b installed on the foundation of the wooden building, in the present embodiment, using a perforation device c as shown in FIG. A dowel hole 1 is provided at a predetermined angle with respect to the column b, for example, at an angle of about 30 ° from a substantially vertical side surface of the column, and the base a and the column b communicate with each other. The dowel hole 1 preferably has a length that does not penetrate the base a. That is, since the dowel hole 1 does not penetrate, the adhesive remains in the base a during the injection of the adhesive described below.

穿孔装置cは、被穿孔体基準面、本実施の形態では柱bの側面に対して所定の角度で被穿孔体に対し穿孔を行う装置で、図3に示すように、ドリルなどよりなる穿孔用工具c1に、角度固定用の治具c2を取り付けたものであり、治具c2は所望の角度に応じて角度調整が可能な角度調整部c21及び穿孔に伴って穿孔用工具c1の移動を可能とする可動部c22から成る。   The piercing device c is a device for piercing the pierced body at a predetermined angle with respect to the pierced body reference plane, in this embodiment, the side surface of the column b, and as shown in FIG. The jig c2 for fixing the angle is attached to the tool c1. The jig c2 moves the drilling tool c1 with the angle adjusting unit c21 capable of adjusting the angle according to a desired angle and the drilling. The movable part c22 is made possible.

次に、図4に示すように、ダボ孔1内に挿入可能な先細吸引口eを備えた吸引式の掃除機Eにてダボ孔1内の木粉をできるだけ完全に除去する。   Next, as shown in FIG. 4, wood powder in the dowel hole 1 is removed as completely as possible by a suction-type cleaner E having a tapered suction port e that can be inserted into the dowel hole 1.

次に、接着剤fをダボ孔1内に注入する。この注入には図5に示すようにダボ孔1内に挿入可能なノズルを備えた注入器Fが用いられる。   Next, the adhesive f is injected into the dowel hole 1. For this injection, an injector F having a nozzle insertable into the dowel hole 1 is used as shown in FIG.

次に、上記したダボ孔1内に注入される接着剤と同等の接着剤fを木ダボdに塗布する。
なお、接着剤としては、例えば、木材同士を強固に接着し、硬化後に弾性を有する接着剤、例えばポリウレタン樹脂系接着剤などが用いられる。
Next, an adhesive f equivalent to the adhesive injected into the dowel hole 1 is applied to the wooden dowel d.
In addition, as the adhesive, for example, an adhesive that firmly adheres wood to each other and has elasticity after curing, for example, a polyurethane resin-based adhesive is used.

次に、上記木ダボdを、図6に示すように、柱bの側面に穿設したダボ孔1より斜めに打設する。これにより、土台a及び柱bが緊結固定される(図1参照)。なお、好ましくは、接着剤固化のために、2〜3日の養生を行う。   Next, as shown in FIG. 6, the wooden dowel d is cast obliquely from the dowel hole 1 formed in the side surface of the pillar b. Thereby, the base a and the column b are tightly fixed (see FIG. 1). Preferably, curing is performed for 2 to 3 days for solidification of the adhesive.

本発明の結合構造によると、木ダボdが、土台a及び柱bによって構成された柱脚接合部内部に相互に連通可能なダボ孔1にわたって挿通され、かつ、接合部において斜め方向に木ダボdが設けられることから、この接合部において十分な強度を発揮することが可能となる。   According to the joint structure of the present invention, the wooden dowel d is inserted through the dowel hole 1 which can communicate with each other inside the column-base joint formed by the base a and the column b, and the wooden dowel is obliquely inserted at the joint. Since d is provided, it is possible to exhibit sufficient strength at this joint.

また、この木ダボdによる結合構造によれば、木ダボが外部に突出することがないことから、土台と柱、柱と梁など、それぞれの外側面のみの外観となり、このことから、美観に優れ、化粧仕上げを施すにも都合の良い接合部となるとともに、さらに筋交いなどを構成させる際や、壁体を構成させる際の妨げにならない。   In addition, according to the connection structure of the wooden dowel d, since the wooden dowel does not protrude to the outside, only the outer surfaces of the base and the pillar, the pillar and the beam, etc. are provided. It is an excellent joint that is convenient for applying a decorative finish, and does not hinder the formation of braces or the formation of a wall.

また、この結合構造では、土台a及び柱bと同等の素材である木ダボdにて接合されることから、従来のような熱橋となって起こる結露などが発生するおそれがない。   In this connection structure, since it is joined by the wooden dowel d, which is the same material as the base a and the column b, there is no possibility that dew condensation or the like that occurs as a conventional thermal bridge occurs.

さらに、土台a及び柱bに対して、木ダボdが斜め方向の接合であることで、この木ダボdが曲げ方向及び引抜き方向の抵抗力を発揮することができる。そして、母材である土台aと柱bとなじみやすく、従来のような金属製ボルトや鋼棒など剛性の高い部材に比べ、この接合部での割裂破壊を起こしにくくなるという効果を得ることができる。   Furthermore, since the wooden dowel d is joined to the base a and the column b in an oblique direction, the wooden dowel d can exert resistance in the bending direction and the pull-out direction. In addition, the base a and the column b, which are the base materials, are easily compatible with each other, and it is possible to obtain an effect that splitting failure at the joint is less likely to occur than a conventional rigid member such as a metal bolt or a steel rod. it can.

特に、本発明の結合構造によると、新築建物はもちろん、既存建物の補強も、ジャッキアップなど大がかりな工事をすることなく容易に行えるという利点がある。   In particular, according to the connection structure of the present invention, there is an advantage that reinforcement of an existing building as well as a new building can be easily performed without large-scale construction such as jacking up.

なお、上述した実施の形態では、土台a及び柱bから成る柱脚接合部について説明したが、横架材a’及び柱bから成る柱脚接合部及び柱頭接合部についても同様に実施することができる。   In the above-described embodiment, the column-base joint composed of the base a and the column b has been described. However, the column-base joint and the column-cap joint composed of the horizontal member a ′ and the column b may be similarly implemented. Can be.

柱頭接合部においては、図7(a)に示すように、横架材a’の上面より、横架材a’に対して所定の角度で、横架材a’及び柱bを相互に連通可能なダボ孔1’を設け、以下、上述した柱脚接合部と同様の手順により、図7(b)に示すように、横架材a’及び柱bを斜めに打設した木ダボdにより緊結固定する。   As shown in FIG. 7 (a), the horizontal member a 'and the column b communicate with each other at a predetermined angle with respect to the horizontal member a' from the upper surface of the horizontal member a 'at the joint portion of the capital. A possible dowel hole 1 'is provided, and a wooden dowel d in which the horizontal member a' and the column b are obliquely cast as shown in FIG. To secure.

また、上述した実施の形態では、ダボ孔1を、ほぞ及びほぞ孔を避けて穿設する例として説明したが、図8に示すように、このダボ孔1を土台aが有するほぞ孔2及び柱bが有するほぞ3を連通するよう穿孔する構成としてもよい。このよなダボ孔1とすると、図9及び図10に示すように、ダボ孔1より注入される接着剤fをほぞ孔2及びほぞ3間の隙間に充填させることが可能となり、接着剤層f23を設けることも可能である。このような構成とすることで、土台aと柱bとの結合強度を増加させることができ、上記本発明の斜めに挿入される木ダボとともに、十分な強度を得ることのできる結合構造となる。   Further, in the above-described embodiment, the dowel hole 1 is described as an example in which the dowel hole is formed so as to avoid the tenon and the tenon hole. However, as shown in FIG. It is good also as a structure perforated so that the tenon 3 which pillar b has may be connected. With such a dowel hole 1, as shown in FIGS. 9 and 10, the adhesive f injected from the dowel hole 1 can be filled into the gap between the mortise hole 2 and the tenon 3, and the adhesive layer It is also possible to provide f23. With such a configuration, the bonding strength between the base a and the column b can be increased, and together with the above-described obliquely inserted wooden dowel of the present invention, a bonding structure capable of obtaining sufficient strength can be obtained. .

さらに、上述した実施の形態では、ダボ孔1の穿設数を対向するような2カ所とし、それぞれに木ダボdを挿入する例として説明したが、これらダボ孔1及び木ダボdの数及び向きは特に限定されるものではなく、互いが干渉しなければ複数で任意に構成してもよく、また、ダボ孔1の穿設角度についても、上記した約30°に限らず、その他の角度、或いは、複数種の角度を組み合わせて構成してもよい。   Furthermore, in the above-described embodiment, the number of the dowel holes 1 is set to two opposing positions, and the wooden dowel d is inserted into each of the two places. However, the number of the dowel holes 1 and the wooden dowel d The direction is not particularly limited, and a plurality may be arbitrarily configured as long as they do not interfere with each other. In addition, the drilling angle of the dowel hole 1 is not limited to about 30 ° as described above, and other angles may be used. Alternatively, a plurality of angles may be combined.

また、上述した実施の形態では、木材として、柱などの縦材と、土台や梁,横架材などの横材との結合について説明したが、縦材と縦材、例えば柱状部材の長手方向に連結する構造や、横材と横材、例えば梁と桁とを連結する構造など、木材同士の結合構造であれば、どの方向を長手方向とするものでもよく、上記同様に互いの接合部分を強固に結合することが可能である。   Further, in the above-described embodiment, the connection between the vertical member such as the pillar and the horizontal member such as the base, the beam, and the horizontal member is described as the wood, but the vertical member and the vertical member, for example, the longitudinal direction of the columnar member are used. Any structure may be used as long as it is a connection structure between timbers, such as a structure that connects to a timber, or a structure that connects a horizontal member to a horizontal member, for example, a beam to a girder. Can be firmly bonded.

さらに、上述した実施の形態では、接着剤をダボ孔1内に注入し、木ダボdに接着剤を塗布する構成として述べたが、このような接着剤を用いずに、穿設されたダボ孔1内に木ダボdを圧入するのみで構成させることとしても良い。このような接着剤を使用しない構成とした場合においても、上記したような土台aと柱bとの接合部に、斜めに木ダボdが設けられる構成とされることから、十分な強度を持った結合構造を得られ、上記同様の効果を得られることとなる。そして、接着剤を使用しない構成であることから、接着剤を積極的に使用することの不可能な個所などに対応でき、そのような個所においても十分な結合構造を得ることができる。   Furthermore, in the above-described embodiment, the configuration has been described in which the adhesive is injected into the dowel hole 1 and the adhesive is applied to the wooden dowel d. However, the dowel is formed without using such an adhesive. It is also possible to adopt a configuration in which only the wooden dowel d is pressed into the hole 1. Even in the case where such an adhesive is not used, since the wooden dowel d is provided diagonally at the joint between the base a and the column b as described above, it has sufficient strength. Thus, an effect similar to the above can be obtained. And since it is the structure which does not use an adhesive agent, it can respond to the place where an adhesive cannot be used positively, etc., and a sufficient joint structure can be obtained also in such a place.

また、上述した実施の形態では、図2に示すような穿孔装置cを用いてダボ孔1を穿設し形成する例について述べたが、上述した構造の装置に限定されることはなく、被穿孔体基準面に対して所定の角度で穿孔を行うことの可能な機能を有する装置であれば、何れの構造であってもよく、さらには、このような構成装置を用いることなく穿設を行うこととしても、上記効果は得られるものである。   Further, in the above-described embodiment, the example in which the dowel hole 1 is formed by drilling using the punching device c as shown in FIG. 2 has been described. However, the present invention is not limited to the device having the above-described structure. Any structure may be used as long as it has a function capable of performing drilling at a predetermined angle with respect to the drilling body reference plane, and furthermore, the drilling may be performed without using such a configuration device. Even if it does, the above-mentioned effect is obtained.
