【従来の技術】本考案は、木材の組み付け方法及びこれに使用する固定具に関し、木材のほぞ穴とほぞの組み合わせに使用する込み栓を容易に固定して、接合力、耐震性を増加する木材の接合方法及び、使用する固定具に関するものである。
【０００２】
【考案が解決しようとする課題】木造建築において、木材同士の接合は各部位により様々な方法が開発されているが、横架材と柱の接合において、図１、に示すように横架材１に柱２を固定するときは、横架材１に角穴６を形成し、柱２の端部に角穴６に入るほぞ７を形成し、それぞれ所定の位置に 丸穴、又は角穴を加工し、穴位置のずれに依って、固定効果の程を計っていた、穴位置は、横架材穴４の位置より、柱５の位置は平均３ｍｍ程度低くして加工し、接合する木材の種類、又は状態によって、それぞれの穴加工位置をずらしていた、例えば、堅い木材や乾燥の進んだ木材は、穴、４，５のずれ幅は小さく、反対に、柔らかい木材や水分の多い木材は、穴、４，５のずれ幅を大きく取り、ほぞの固定力を加減していた、組付けは横架材穴６に、柱の端部に加工したほぞ７を嵌入して、この穴、４，５に、丸棒状又は角棒状に加工した込み栓、図１、３を打ち込み、図１、（Ｂ）に示すように、柱２，を横架材１の方向に引き寄せ固定する事が出来た。又近年、図２に示す様な、簡便なほぞ締結用込み栓が、開発された、（特許第３０４８５６２号参照）。これは横架材にほぞを嵌入させた後、ドリル等で所定の位置に穴加工をして、ほぞをさらに嵌入させるべく、その方向に切断可能な断面円弧の肉厚部を設け、その下部にほぞが嵌入しても障害にならないよう切り欠き部を設け、円筒内部の肉厚部の下部にピンが嵌入すると肉厚部が外部に押されて出る突起が有り、ピンの嵌入とともに肉厚部がほぞ嵌入方向に押され横架材と柱を固定することが出来た。
【０００３】
【考案が解決しようとする課題】しかしながら従来の木質込み栓の装着には、多年の経験と長い時間を要した。
【０００４】
又近年開発された（特許３０４８５６２号）は、図２に於いて説明すると断面円形ピン１１が嵌入され、１番目の当接部肉厚８の傾斜部に当たると、力は第１当接傾斜部端部にかかり、先ず端部が外側に斜めに押されると同時に反対側の端部は本体１０ａに当たり、さらに嵌入を進めると、肉厚部内部の円弧面を外側に押し出すが、この時点で以下の現象が起こる恐れがあった。
（１）樹脂製の本体と、金属製の円形ピンを使用した場合には、嵌入力によって発生する、押し上げ力が、ほぞに使用された木材の堅さとの関係で反対側の端部が当たる本体１０ａ部と波線１２の処いわゆる先端片方の支持部が破損する、又破損までしないでも傾斜部の影響で、傾斜した状態でほぞに作用する可能性がある、肉厚部８の外表面面積と下部突起の高さ選定が困難であり、使用する木材、又はほぞの長さで種種作る必要があった。
（２）金属製の本体と円形ピンを使用した時は、前記（１）説明の嵌入時肉厚部８の端部が横架材１のほぞ穴の側壁、図１ａ部に突き刺さる可能性がある（３）このような状態であるから、ほぞの長さ、木質を勘案しそれぞれに合った、肉厚部８を作らないと、効果的な機能を発揮しない恐れがある。本考案はこのような事情を鑑みてなされたもので、木に平均な力が作用するほぞ固定装置を提供する
【０００５】
【課題を解決するための手段】前記目的を可能にする本考案の接合方法は、横架材１のほぞ穴に柱２の端部に形成されたほぞを嵌入して、嵌入した状態で、横架材とほぞを貫通する丸穴をドリル等で形成し、形成したほぞ穴に、強靱でなをかつ可とう性を有したプラスチック製のほぞを貫通する当接面積の違う８角形の投錨用断続角体と金属製の釘を有し中央より縦長に分断用薄肉で繋がり、ほぞ部の端面の位置に案内位置決め用斜面部を有し、内部に貫通する寸法の異なる四角穴と片方入り口に、縦横の寸法の違う金属製四角柱の釘の挿入方向確認の窓と挿入寸法を決める鍔を有し、前記角体に釘を方向確認し挿入し前記ドリルで形成された穴に挿入し、さらに釘を挿入する、ここでほぞ嵌入方向に位置する前記角体の四角穴は釘の縦横いずれの幅より短くして押し広げる効果を計っている、又釘の直進を妨げる障害物はない。
【０００６】
ここで前記ドリルで形成された穴に釘を装着された前記角体が挿入されさらに釘が進入するとほぞ嵌入方向に対し上下に分断面から押し広げられ横架材部はほぞ嵌入方向とは逆に当接面積を増しほぞ部は嵌入方向に当接面積を増しているので釘の進入につれて断続的に作られた角体が当接面積の耐力に従って上下に食い込みずれることがない又ほぞ部と横架材の境界にまたがる位置に補正案内用斜面を設けているのでほぞ部に平行に作用する、又釘の頭部は角体鍔部より大きく作っている、これは木材の防腐剤に万能に耐えるプラスチックが乏しいから、装着後横架材の表面に出るのは釘の頭だけとするのが好ましい。
【０００７】
【作用】本考案では次のような作用を生じる。可とう性を有した強靱なプラスチック製の投錨用断続角体と各部に当接面積の違いを有した本体はほぞ穴に挿入後金属製の釘の進入により、中央より分離されつつ当接面積の耐力に従って、ほぞ穴の中心線より釘の中心線をずらし乍ら進入しほぞ部を過ぎて最後の当接面積を増した部分に釘が達してから、ほぞ嵌入方向の当接面積を増した部分と両端の当接面積を増した部分にそれぞれ力が直角方向に作用してほぞ部当接面積を増した部分を嵌入方向に平行に押し出す作用がある。
【０００８】又、縦横寸法の違う四角柱の釘を用いることによりほぞを固定する力加減を２種類持つ利便さが有りほぞの長さに依る耐力や木材の堅さの違いにも現場で対応出来る、又８角形とする事でずれを防止して木材の耐力に対して暖衝適役割も期待できる。
【０００９】なを本体は投錨用断続角体を有し四角柱の釘がより寸法の狭い内部四角穴に入ることによって、中央より分離し木材の穴に食い込ませながらの装着であるから釘は抜けにくくより耐震効果が期待できる。
【００１０】
【実施例】以下本考案の実施形態について、添付した図面を参照しつつ詳しく説明する。
【００１１】
本考案の木材の接合方法に用いる固定装置は、投錨用断続角体図３は強靱で可とう性を有したプラスチックと釘図４で構成されている。この固定装置は、横架材１に形成されたほぞ穴６に、柱の端部に形成されたほぞ７を嵌入し、ドリル等で形成された同心穴に挿入し釘を嵌入して、横架材と柱とを固定するものである。
【００１２】
図３（Ｅ）に示すように固定用角体は八角形とし当接面積の大きいＬ１．Ｌ２．Ｌ３の半８角外径、角は前記同心穴の半分の内径円弧に接し図５、（Ｈ）１６，は各８角鍔間の少し低い位置で各鍔間を連鎖し投錨効果を持たせている、これによって表面積が大きくなり力の分散と吸収が出来る対向するＬ４、Ｌ５，Ｌ６の半８角外径は前記同心穴内径図５，（Ｈ）１７、より小さく頂点に前記内径と等しい位置に投錨用半円球の突起１４，を設け当接面積を小さくしている、これによって内接する前記穴に食い込み安くしている対向する半径で当接面積を変える事によって、釘を嵌入した時は前記同心穴の中心線より交互にずれながらほぞ部を通過し最後の当接面積を増した部分に嵌入が始まってから全体に釘と直角方向に力が働き、両端Ｌ１．Ｌ３の部分が土台となってＬ２，を押し上げるＬ２，の両端面境界部図３，１８，に斜面をつけているのでほぞ部よりずれにくくなっている。なおＬ２．はほぞ７の厚みと等しくＬ１、Ｌ４、は横架材の穴４の長さと等く角体縦長中央に釘図４，の嵌入時上下に分断可能な薄肉部図５，（Ｈ）１９を対向する側面にも設けている、成形する金型を考慮して薄肉部を片方だけとし対向する薄肉部を廃しヒンジ効果を持たせても良いこうすると金型作りと成形作業を容易にする。
【００１３】
図７，（Ｌ）は固定用角体端部の釘進入口の断面である、縦横寸法の違う釘をこの四角穴に入れると止まる位置で分断の強弱が判断できる２０、で止まれば大きく押し広げ２１で止まれば小さく押し広げそれをのぞき窓２２で確認して前記同心穴に挿入するなお四角横方向（Ｌ７）は釘縦横どちらの寸法も入るようにしている挿入する方向は左右分断面及び角体外形状で容易に判断できるすなわち力を発揮する方向に中央（Ｌ２）部を向け分断面を直角にする、先ず釘を（Ｌ１，Ｌ４）第１嵌入部に嵌入するすると図５，（Ｉ）の様に（Ｌ１）部の当接面積を増した部分を土台として当接面積の小さい（Ｌ４）部が対向する同心穴の内円弧に圧接され双方が分断されつつ食い込み投錨効果を生みさらに釘を（Ｌ２，Ｌ５）第２嵌入部に嵌入するすると第２嵌入部は第１嵌入部と逆の状態に分断圧接され第３嵌入部（Ｌ３，Ｌ６）の位置に嵌入分断が始まってから（Ｌ１，Ｌ３）が土台となって（Ｌ２）部を平行に押し上げる連鎖された連続角体なので一部のみの突出でなく当接面積により釘の押し上げ力の位置を変えているなをこの時（Ｌ４、Ｌ５，Ｌ６）部は当接面積を小さくしているので前記押し上げる力の妨げにならないこのようにして横架材１，の前記同心穴の図６、２４，２５，の２面が（Ｌ１，Ｌ３）が土台としてほぞ穴を（Ｌ２）部が平行に押しほぞを固定する事が出来る。
【００１４】
このように構成することで短時間で接合材に合った施工が出来る
【００１】
【考案の効果】請求項１記載のほぞ固定装置に於いて固定穴はドリル加工なので短時間に出来き、釘の入れる方向ものぞき窓があるので的確に出来る、又角体の挿入方向も中央当接面積を増した部分を嵌入方向に向け薄肉分段面を直角方向にして挿入すればよいので判りやすい当接面積を変えた断続角体なので釘の嵌入で長手方向中央より分断され木材施工穴内にそれぞれ食い込み抜けにくく、又暖衝適役割も果たしずれることがない、２点の当接面積を増した部分がてこの役割をして他方中央の当接面積を増した部分を持ち上げるので力の効果に無理がなく経時変化しにくい又請求項２記載の固定装置は、四角釘の２辺の寸法を変えているので押し広げる力が２種類有り現場現況での対応が出来る。釘の頭部を角体鍔部より大きくする事で防腐剤による角体の劣化や、火災の損傷を防ぎ固定装着後木材との違和感も少なくすることが出来る。

BACKGROUND OF THE INVENTION The present invention relates to a method of assembling wood and a fixing tool used for the same, which easily fixes a plug used in a combination of a tenon and a tenon of wood to increase joint strength and earthquake resistance. The present invention relates to a method for joining wood and a fixture to be used.
[0002]
[Problems to be Solved by the Invention] In a wooden building, various methods of joining timber to each other have been developed depending on each part. In joining a horizontal member and a pillar, as shown in FIG. When the column 2 is fixed to 1, a square hole 6 is formed in the horizontal member 1, and a tenon 7 is formed at the end of the column 2 to enter the square hole 6. And the degree of the fixing effect was measured depending on the displacement of the hole position. The hole position was lower than the position of the horizontal member hole 4 by an average of about 3 mm at the position of the column 5 and then joined. Depending on the type or condition of the wood, the hole processing position was shifted. For example, in the case of hard wood or dry wood, the gap between holes 4 and 5 is small, and on the contrary, soft wood or water-rich For wood, the gap between the holes and 4, 5 was large, and the tenon fixing force was adjusted. A tenon 7 machined at the end of the pillar is inserted into the hole 6, and a plug formed into a round bar or a square bar, FIGS. As shown in ()), the column 2 was able to be pulled in the direction of the horizontal member 1 and fixed. Recently, a simple tenon fastening plug as shown in FIG. 2 has been developed (see Japanese Patent No. 3048562). In this method, after a tenon is inserted into the horizontal member, a hole is drilled at a predetermined position with a drill or the like, and a thick section having a circular cross section that can be cut in that direction is provided in order to further insert the tenon. A notch is provided so that it does not become an obstacle even if the tenon is inserted. There is a projection at the bottom of the thick part inside the cylinder when the pin is inserted, and the thick part is pushed out and comes out. The part was pushed in the direction of the tenon insertion, and the horizontal member and the column could be fixed.
[0003]
[Problems to be Solved by the Invention] However, the installation of the conventional wooden plug requires a lot of experience and a long time.
[0004]
Further, in recent years (Japanese Patent No. 3048562), when a pin 11 having a circular cross section is fitted and hits an inclined portion having a first contact portion having a thickness of 8 as described in FIG. At the same time, the end is pushed obliquely outward, and at the same time the opposite end hits the main body 10a, and when further fitting is advanced, the arc surface inside the thick part is pushed out, but at this point There was a possibility that the phenomenon described above would occur.
(1) When a resin main body and a metal circular pin are used, the push-up force generated by the fitting input hits the opposite end in relation to the hardness of the wood used for the tenon. The outer surface area of the thick portion 8 where the main body 10a and the so-called one end supporting portion of the wavy line 12 may be damaged, and even if not damaged, it may act on the tenon in an inclined state under the influence of the inclined portion. In addition, it is difficult to select the height of the lower protrusion, and it is necessary to make various kinds of wood or tenon length.
(2) When a metal main body and a circular pin are used, there is a possibility that the end of the thick part 8 at the time of insertion described in the above (1) may pierce the side wall of the mortise of the horizontal member 1, that is, the portion of FIG. (3) In such a state, there is a possibility that an effective function may not be exhibited unless the thick portions 8 are formed in consideration of the length of the tenon and the quality of the wood, and are adapted to each. The present invention has been made in view of such circumstances, and provides a tenon fixing device in which an average force acts on a tree.
The joining method according to the present invention, which makes the above object possible, comprises: inserting a tenon formed at the end of a pillar 2 into a tenon of a horizontal member 1; An octagonal anchor with a different contact area that penetrates a rigid tenacity and flexibility plastic tenon in the formed tenon by forming a round hole that penetrates the transverse member and tenon with a drill or the like. A rectangular hole and a single entrance with different dimensions penetrating inside, with an intermittent horn and a metal nail, connected vertically from the center with a thin wall for dividing, a guide positioning slope at the end face of the tenon In addition, it has a window for checking the insertion direction of nails of metal square pillars with different vertical and horizontal dimensions and a flange that determines the insertion dimension, confirms the direction of the nail in the square body, inserts it and inserts it into the hole formed by the drill Insert the nail further, where the square hole of the rectangular body located in the tenon insertion direction is And measure the effect of pushing made shorter than the width of the record, there is no obstacle that blocks straight of Matakugi.
[0006]
Here, when the square body with the nail attached is inserted into the hole formed by the drill and the nail is further advanced, the nail is pushed up and down from the cross section vertically in the tenon insertion direction, and the horizontal member portion is opposite to the tenon insertion direction. The contact area is increased and the tenon part increases in the fitting direction, so that the intermittently made horns do not bite up and down according to the contact area's strength as the nail enters. A correction guide slope is provided at the position that straddles the border of the horizontal member, so it works in parallel with the tenon. The head of the nail is made larger than the square flange, which is used as a wood preservative. Due to the lack of universal plastic, it is preferable that only the nail heads come out on the surface of the horizontal member after mounting.
[0007]
[Function] The present invention has the following functions. The flexible plastic anchoring interrupted horn and the body with different contact areas at each part are separated from the center by the insertion of metal nails after insertion into the mortise, and the contact area is separated from the center. In accordance with the proof strength, the nail enters into the hole with the center line of the mortise shifted from the center line of the mortise, and after the nail reaches the part where the last contact area has increased after passing through the tenon, the contact area in the tenon insertion direction increases. A force acts on the portion where the contact area is increased at both ends and the portion where the contact area is increased at both ends, so that the portion where the contact area with the tenon is increased is pushed in parallel with the fitting direction.
In addition, by using square pillar nails having different vertical and horizontal dimensions, there is the convenience of having two types of force for fixing the tenon, and it is possible to cope with differences in strength and wood hardness depending on the tenon length. The octagonal shape can be used to prevent misalignment, and it can also be expected to play a role in optimizing the resistance to wood.
[0009] The main body has an intermittent prism for anchoring, and the square pillar nail is inserted into the smaller inner square hole, so that it is separated from the center and installed while cutting into the hole in the wood. It is hard to come off, and the anti-seismic effect can be expected.
[0010]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
[0011]
In the fixing device used in the method for joining wood according to the present invention, the intermittent prism for anchoring FIG. 3 is composed of a tough and flexible plastic and a nail FIG. This fixing device inserts a tenon 7 formed at the end of a pillar into a tenon 6 formed in the horizontal member 1, inserts it into a concentric hole formed by a drill or the like, and inserts a nail. It fixes the frame and the pillar.
[0012]
As shown in FIG. 3 (E), the fixing prism is an octagon, and L1. L2. The half octagonal outer diameter and the corner of L3 are in contact with the inner diameter arc of half of the concentric hole, and FIG. 5 (H) 16 shows that the flanges are linked at a slightly lower position between the octagonal flanges to provide an anchoring effect. The octagonal outer diameters of the opposing L4, L5, and L6, which increase the surface area and can disperse and absorb the force, are smaller than those of the concentric hole inner diameter diagram 5 (H) 17 shown in FIG. A nail 14 is provided at the position to reduce the contact area by providing a semicircular projection 14 for anchoring. The nail is fitted by changing the contact area with the opposite radius which makes it easier to cut into the inscribed hole. At the time, after passing through the tenon while alternately deviating from the center line of the concentric hole, the fitting starts at the portion where the last contact area is increased, and then a force acts in a direction perpendicular to the nail as a whole, so that both ends L1. Since the portion of L3 serves as a base and pushes up L2, the slope of the boundary between both ends of L2 (FIGS. 3 and 18) makes it harder to shift than the tenon. Note that L2. L1 and L4 are equal to the thickness of the tenon 7, and L1 and L4 are the same as the length of the hole 4 of the horizontal member. Considering the mold to be molded, which is also provided on the opposite side surface, only one thin portion may be used, and the opposed thin portion may be omitted to provide a hinge effect. This facilitates the mold making and molding operation.
[0013]
FIG. 7 (L) is a cross-section of the nail entrance at the end of the fixing horn, and if a nail with a different length and width is inserted into this square hole, the strength of the division can be determined at the position where the nail stops. If it stops at the spread 21, it is pushed small and spreads, and it is confirmed through the view window 22 and inserted into the concentric hole. The square horizontal direction (L 7) is set so that both the vertical and horizontal dimensions of the nail can be inserted. The center (L2) is oriented in the direction in which the force can be exerted, that is, the center (L2) is oriented in the direction in which the force is exerted. ), The portion having the increased contact area of the portion (L1) is used as a base, and the portion (L4) having a small contact area is pressed against the inner circular arc of the concentric hole facing each other to produce a biting and anchoring effect while being cut off. Insert the nail into the (L2, L5) second insertion part Then, the second fitting portion is divided and pressed in a state opposite to that of the first fitting portion, and after the fitting and splitting starts at the position of the third fitting portion (L3, L6), (L1, L3) becomes a base (L2) portion. Are pushed up in parallel, so that the position of the pushing force of the nail is changed according to the contact area instead of the projection of only a part. At this time, the contact area is small in the (L4, L5, L6) part. In this way, the two surfaces of the concentric holes of the horizontal member 1 shown in FIGS. 6, 24, 25 (L1, L3) are used as bases to form the mortise (L2). The part can hold the tenon in parallel.
[0014]
With this configuration, it is possible to perform the work suitable for the bonding material in a short time.
According to the invention, the fixing hole can be formed in a short time because the fixing hole is drilled, and it can be precisely formed because there is a sight glass for inserting the nail. It is only necessary to insert the part with the increased contact area in the insertion direction with the thin-walled dividing step surface at right angle, so it is easy to understand.Since the contact area is changed, it is cut off from the center in the longitudinal direction by the insertion of nails. It is difficult to penetrate into the holes, and it does not shift the role of warmth. The part with the increased contact area at the two points plays the leverage role and lifts the part with the increased contact area at the center. In the fixing device according to the second aspect, the size of the two sides of the square nail is changed, so that there are two kinds of pushing forces and the fixing device according to the second aspect can cope with the present situation at the site. By making the head of the nail larger than the horn body, deterioration of the horn body due to preservatives and fire damage can be prevented, and the feeling of discomfort with wood after fixed mounting can be reduced.
