Abstract

<P>PROBLEM TO BE SOLVED: To solve a problem wherein there is a joining method of directly applying an adhesive to tenons to enhance joint strength between a column and a sill and between the column and a beam, but work of assembling while applying the adhesive to each tenon of a building is unrealistic because of requiring great labor, and furthermore, if the adhesive is applied to the tenon to insert it in a mortise, the adhesive is hardened in an instant by frictional heat to make even complete fitting difficult, not to mention correction to make the column perpendicular. <P>SOLUTION: In this joint structure of a building material, a male part 6 is formed at a vertical member 2 (the building material), while a non-penetrating female part 5 is formed in a horizontal member 1 (the building material), and the male part 6 and the female part 5 are fitted to join both members. In this case, a liquid adhesive 7 filled in a bag 8 is installed as it is bagged between the male part 6 and the female part 5, and the bag 8 is burst to press the adhesive 7 into the fitting part of the male part 6 and female part 5 by the pressure of fitting the male part 6 and female part 5. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

本発明は、土台、梁、柱等の建築用材を接合する接合構造及びその接合構造を有する建物に関する。   The present invention relates to a joint structure that joins building materials such as foundations, beams, and columns, and a building having the joint structure.

建物の強度は、土台、梁、柱等の建築用材同士の接合強度に大きく依存する。現に、地震で倒壊した建物を調査すると、土台のホゾ穴から柱のホゾが抜けているものが多々ある。   The strength of a building greatly depends on the joint strength between building materials such as foundations, beams and columns. In fact, when investigating buildings that collapsed due to an earthquake, there are many cases where pillars are missing from the foundation holes.

このような柱と土台又は柱と梁（又は桁）の接合強度を高めるため、ホゾ又はホゾ穴内に接着剤を直に塗布して接着する方法が例えば特許文献１などに開示されている。
実用新案登録第３０９８３０４号公報 For example, Patent Document 1 discloses a method in which an adhesive is directly applied and bonded to a side wall or a side hole in order to increase the bonding strength between the column and the base or the column and the beam (or the beam).
Utility Model Registration No. 3098304

建物の個々のホゾ又はホゾ穴内に接着剤を直に塗布しながら組み立てる、という作業は、多大な労力を要するため現実的でない。
しかしそれよりホゾ又はホゾ穴内に接着剤を直に塗布して接着する方法にはさらに致命的な欠点が存在する。すなわち本発明者の実験によれば、ホゾに接着剤を直に塗布してホゾ穴に差し込むと、ホゾとホゾ穴の嵌合が密である場合に嵌合時に摩擦熱が発生し、その摩擦熱により接着剤が瞬時に硬化するため、柱を垂直にする修正はおろか、完全な嵌合さえ難しい、ということが判明した。
なお、以上のことはホゾとホゾ穴のような縦用材（柱等）と横用材（梁、桁等）を直交させて接合する「仕口」はもちろん、長手方向に建築用材同士を継ぎ足す「継手」の場合も同様である。 The work of assembling while applying adhesive directly into individual ridges or cavities in a building is not practical because it requires a great deal of labor.
However, there is a more fatal drawback in the method of directly applying and bonding the adhesive into the side wall or the side hole. That is, according to the experiment of the present inventor, when the adhesive is directly applied to the tenon and inserted into the tenon hole, friction heat is generated at the time of fitting when the tenon and the tenon hole are densely fitted. It turns out that the adhesive hardens instantly due to heat, so that it is difficult to make a perfect fit, let alone make the pillars vertical.
In addition, the above is not only a "joint" that joins vertical materials (columns, etc.) and horizontal materials (beams, girders, etc.), such as hozos and hozo holes, but also adds building materials in the longitudinal direction. The same applies to the “joint”.

本発明は上記に鑑みなされたもので、その目的は、接着剤による建築用材同士の接合を実現可能とし、また、そのような接合構造を使用した建物を提供することにある。   The present invention has been made in view of the above, and an object of the present invention is to provide a building using a bonding structure that enables bonding of building materials with an adhesive.

１本の建築用材に雄部を形成し、別の１本の建築用材に非貫通の雌部を形成し、その雄部と雌部を嵌合させて接合するようにした建築用材の接合構造であって、
袋に封入した流動性を有する接着剤を前記雄部と雌部の間に袋詰めのまま設置し、雄部と雌部を嵌合させる圧力で、前記袋を破裂させると共に雄部と雌部の嵌合部に接着剤を圧入させるようにした建築用材の接合構造を提供する。 A construction structure for building materials in which a male part is formed on one building material, a non-penetrating female part is formed on another building material, and the male part and the female part are fitted and joined. Because
The adhesive having fluidity enclosed in a bag is placed between the male part and the female part in a bag-packed state, and the bag is ruptured by the pressure for fitting the male part and the female part, and the male part and the female part Provided is a construction material joining structure in which an adhesive is press-fitted into the fitting portion.

また、請求項２に記載したように、前記袋は、２枚の袋基材の周縁を溶着してその溶着部から破裂するものである請求項１記載の建築用材の接合構造を提供する。   According to a second aspect of the present invention, there is provided the building material joining structure according to the first aspect, wherein the bag is formed by welding the peripheral edges of two bag base materials and rupturing from the welded portion.

また、請求項３に記載したように、前記雄部と雌部の間に、雄部と雌部の嵌合圧力で圧縮変形する強度の中間材を介在させるようにした請求項１又は２記載の建築用材の接合構造を提供する。   In addition, as described in claim 3, an intermediate material having a strength that is compressively deformed by a fitting pressure between the male part and the female part is interposed between the male part and the female part. Providing a joint structure for building materials.

また、請求項４に記載したように、請求項１乃至３の何れか１項に記載の接合構造で接合した縦用材と横用材とを有する建物を提供する。   Moreover, as described in Claim 4, the building which has the vertical material and the horizontal material joined by the joining structure of any one of Claims 1 thru | or 3 is provided.

また、請求項５に記載したように、請求項１乃至３の何れか１項に記載の接合構造で接合した縦用材と横用材と、
直角に突き合わさる２つの取付片とその取付片同士を連結する補強斜片とを有する固定金具で直角に固定した縦用材と横用材と、
を有する建物を提供する。 Moreover, as described in claim 5, the longitudinal member and the transverse member joined by the joining structure according to any one of claims 1 to 3,
A vertical member and a horizontal member fixed at a right angle by a fixing bracket having two mounting pieces that face each other at right angles and a reinforcing slant piece that connects the mounting pieces;
Provide a building with.

本発明によれば建築用材の雌部に雄部を差し込むとき、雄部及び雌部に接着剤が塗布されていないため、通常の打ち込み等の作業で支障なく嵌め込める。そして雌部と雄部が完全に嵌まり合う直前に両者に挟まれて袋が破裂し、中から流動性を有する接着剤が押し出され、その圧力で雌部と雄部の嵌合部に接着剤が圧入され適当な時間をおいて硬化する。もちろん接着剤が硬化すれば建築用材同士の接合強度は飛躍的に向上し、従来工法において建築用材同士の接合部に取り付けていた補強用の金具も不要になる。
また、接着剤は通常の硬化時間を経て硬化するため、硬化するまでの間に建築用材の傾きなどを調整することができる。 According to the present invention, when the male part is inserted into the female part of the building material, since the adhesive is not applied to the male part and the female part, the male part and the female part can be fitted without any trouble in normal operations such as driving. And just before the female part and male part are completely fitted, the bag is ruptured by both of them, the adhesive having fluidity is pushed out from inside, and the pressure adheres to the fitting part of the female part and male part The agent is injected and cured after an appropriate time. Of course, if the adhesive is cured, the bonding strength between the building materials is dramatically improved, and the reinforcing metal fittings attached to the bonding portions between the building materials in the conventional construction method are not required.
Further, since the adhesive is cured through a normal curing time, the inclination of the building material can be adjusted before it is cured.

また、請求項２に記載の発明によれば、２枚の袋基材の溶着した周縁が破れてそこから接着剤が押し出されるため、雌部と雄部の嵌合部に接着剤が入り易い。   According to the second aspect of the present invention, since the welded peripheral edges of the two bag base materials are torn and the adhesive is pushed out therefrom, the adhesive is likely to enter the fitting portion between the female portion and the male portion. .

また、現在の建築工法は、建築用材を工場で機械加工し、現場でそれを組み立てる方式（いわゆるプレカット方式）が多く、その場合には例えばホゾ穴をホゾより深くしてホゾの先とホゾ穴の底が接触しない、つまり誤差などによりホゾがホゾ穴に入りきらない事態が発生しないよう深さ方向に大きい遊びを設けているが、そのような場合にはホゾ穴の底にホゾの先が当たらないから前記袋が破裂しない可能性がある。これに対し請求項３のように雄部と雌部の間に中間材を介在させて雄部と雌部の嵌合圧力で圧縮変形し潰れるようにしておけば、雄部と雌部の嵌合圧力が中間材を介して接着剤の袋に伝わるから、接着剤の袋の確実な破裂が可能になる。   In addition, the current construction method has many methods (so-called pre-cut method) in which building materials are machined at a factory and assembled on site (so-called pre-cut method). There is a large play in the depth direction so that the bottom of the bottom does not touch, that is, the situation where the bottom does not fit into the bottom due to errors etc., but in such a case the tip of the bottom is at the bottom of the bottom The bag may not rupture because it does not hit. On the other hand, if the intermediate member is interposed between the male part and the female part as in claim 3 and is compressed and deformed by the fitting pressure between the male part and the female part, the male part and the female part are fitted. Since the resultant pressure is transmitted to the adhesive bag through the intermediate material, the adhesive bag can be reliably ruptured.

以上の接合構造を採用した請求項４の建物は、接着剤を塗布する手間が掛からないため工期が短く、しかも接合部を接着剤で接着したことにより優れた強度を発揮する。   The building according to claim 4 adopting the above-mentioned joining structure has a short construction period because it does not take time and effort to apply the adhesive, and exhibits excellent strength by bonding the joining portion with the adhesive.

また、請求項５に記載の固定金具で縦用材と横用材を直角に固定する構造は、仮筋止め等を要さずに短時間で正確な軸組みが行えるため、上記した接着剤による接合構造で横用材と縦用材を接合し接着剤が硬化するまでの限られた時間内に軸組みを整えることができる。従って、上記した接着剤による接合構造と、固定金具による接合構造を組み合わせて構成した請求項５の建物は、歪みが無くしかも強度に優れる効果がある。   In addition, the structure in which the vertical member and the horizontal member are fixed at right angles with the fixing bracket according to claim 5 can perform accurate shaft assembly in a short time without the need for temporary stapling or the like. With the structure, it is possible to arrange the shaft assembly within a limited time until the adhesive is cured after the transverse member and the longitudinal member are joined. Therefore, the building according to claim 5 configured by combining the above-described bonding structure using the adhesive and the bonding structure using the fixing metal has an effect of having no distortion and excellent strength.

以下に本発明の実施の形態を図面を参照しつつ説明する。なお、図１は要部の分解斜視図、図２は接合工程を説明する要部の縦断面図、図３は要部の斜視図、図４は要部の正面図、図５は図４のＸ−Ｘ線断面図、図６は袋詰め接着剤の斜視図、図７は要部の分解斜視図、図８は要部の縦断面図、図９は接合工程を説明する要部の縦断面図、図１０は建物の軸組みを示す概略の正面図である。   Embodiments of the present invention will be described below with reference to the drawings. 1 is an exploded perspective view of the main part, FIG. 2 is a longitudinal sectional view of the main part for explaining the joining process, FIG. 3 is a perspective view of the main part, FIG. 4 is a front view of the main part, and FIG.

FIG. 10 is a schematic front view showing a framework of a building.

図１０の軸組みにおいて、符号１は水平な木製建築用材たる横用材を、また符号２は垂直な木製建築用材たる縦用材を示している。図示した横用材１は、コンクリート製の基礎３の上に周知のアンカーボルト（図示せず）で固定した土台１ａと、１階と２階の間にある２階梁１ｂと、軒桁１ｃである。一方、図示した縦用材２は、土台１ａから軒桁１ｃまで連続する通し柱２ａと、土台１ａと２階梁１ｂ又は２階梁１ｂと軒桁１ｃの間に立設した管柱２ｂである。なお、主要な柱間に掛け渡した斜めの建築用材は筋交い４である。   In the shaft assembly of FIG. 10, reference numeral 1 indicates a horizontal member that is a horizontal wooden building material, and reference numeral 2 indicates a vertical member that is a vertical wooden building material. The illustrated horizontal member 1 is composed of a base 1a fixed on a concrete base 3 with a well-known anchor bolt (not shown), a second floor beam 1b between the first floor and the second floor, and an eaves girder 1c. is there. On the other hand, the illustrated vertical member 2 is a through column 2a continuous from the base 1a to the eaves girder 1c, and a pipe column 2b erected between the base 1a and the second floor beam 1b or between the second floor beam 1b and the eaves beam 1c. The diagonal building material spanned between the main pillars is a brace 4.

前記横用材１と縦用材２の第一の接合構造は、図１に示したように、横用材１に断面凹状で非貫通の雌部５たるホゾ穴を穿設すると共に縦用材２に雄部６たるホゾを形成し、前記雌部５に雄部６を嵌合させる周知の仕口と、後述する接着手段の結合である。   As shown in FIG. 1, the first joining structure of the transverse member 1 and the longitudinal member 2 is formed with a transverse hole having a concave cross section and a non-penetrating female portion 5 in the transverse member 1, and the longitudinal member 2 is male. This is a combination of a well-known joint for forming a tenon as the portion 6 and fitting the male portion 6 into the female portion 5 and an adhesive means described later.

前記接着手段は、木材同士の接着に適し且つ流動性を有する例えば酢酸ビニル樹脂系の接着剤７を袋８に詰めたものである。前記袋８は、例えばビニールのごとき合成樹脂の四角い袋基材８ａ，８ｂを２枚重ねにして周縁を溶着してなる。この袋詰め接着剤７を雌部５の底に置き、その雌部５に雄部６を嵌め入れると、図２に示したように嵌合完了一歩手前の段階で雄部６の先と雌部５の底に袋８が挟まれ、強い圧力を受けて溶着部８ｃから破裂し、中の接着剤７が袋８の外に全て押し出される。そしてその強力な圧力で雌部５と雄部６の嵌合部に接着剤７が注入され、さらにその接着剤７が所定の硬化時間を経て硬化する。   The bonding means is a bag 8 filled with, for example, a vinyl acetate resin-based adhesive 7 that is suitable for bonding woods and has fluidity. The bag 8 is formed, for example, by laminating two rectangular bag base materials 8a and 8b made of synthetic resin such as vinyl, and welding the periphery. When this bagging adhesive 7 is placed on the bottom of the female part 5 and the male part 6 is inserted into the female part 5, as shown in FIG. The bag 8 is sandwiched between the bottoms of the parts 5, bursts from the welded part 8 c under strong pressure, and the adhesive 7 inside is entirely pushed out of the bag 8. And the adhesive agent 7 is inject | poured into the fitting part of the female part 5 and the male part 6 with the strong pressure, and also the adhesive agent 7 hardens | cures through predetermined hardening time.

図９はいわゆるプレカット方式の縦用材２と横用材１を示したものである。プレカット方式の建築用材は、雌部５の奥行きを雄部６の高さより深くして雌部５の底に雄部６の先が当たらないよう予め大きめの遊びを設ける場合が多い。何故なら、雌部５と雄部６を嵌め合わせるのに深さ方向の遊びが少ないと、湿気による膨脹や加工精度の誤差により雄部６が雌部５に入りきらない危険性があるからである。このように雌部５の底と雄部６の先に大きい遊びがある場合、雌部５の底と雄部６の先に袋詰めの接着剤７がすっぽりと収まる可能性があり、そうすると接着剤７の袋８が破裂しない。   FIG. 9 shows a vertical material 2 and a horizontal material 1 of a so-called pre-cut method. In many cases, precut construction materials are provided with a large play in advance so that the depth of the female portion 5 is greater than the height of the male portion 6 and the tip of the male portion 6 does not hit the bottom of the female portion 5. This is because if there is little play in the depth direction when the female part 5 and the male part 6 are fitted together, there is a risk that the male part 6 cannot enter the female part 5 due to expansion due to moisture or errors in processing accuracy. is there. In this way, when there is a large play at the bottom of the female part 5 and the tip of the male part 6, the adhesive 7 in the bag may fit completely on the bottom of the female part 5 and the tip of the male part 6, so that The bag 8 of the agent 7 does not rupture.

これを防止するため本発明では図９に示したように、雌部５に例えば発泡スチロール製の中間材９を装填し、その中間材９の上に袋詰めの接着剤７を置いた状態にして雄部６を嵌める。そうすることにより雄部６の嵌合圧力で中間材９が潰れて圧縮変形するため、その間に挟まれる接着剤７の袋８が確実に破裂する。   In order to prevent this, in the present invention, as shown in FIG. 9, an intermediate material 9 made of, for example, styrene foam is loaded in the female portion 5, and the bagging adhesive 7 is placed on the intermediate material 9. Fit the male part 6. By doing so, the intermediate member 9 is crushed and compressed and deformed by the fitting pressure of the male part 6, so that the bag 8 of the adhesive 7 sandwiched therebetween is surely ruptured.

ところで１階の管柱２ｂの頂部と２階梁１ｂの下面の接合部や、軒桁１ｃの下面と縦用材２の頂部の接合部は、雄部６が上向きで雌部５が下向きになるため、袋詰めの接着剤７を雌部５に入れても落下する。そこで図６に示したように袋８の一面に貼着層１０を形成し、この貼着層１０を雌部５の奥に貼り付けるようにするとよい。この袋８の貼着層１０は周知の両面テープを使用することにより簡単に実施できる。   By the way, in the joint between the top of the first-column pipe column 2b and the lower surface of the second-floor beam 1b, and the joint between the lower surface of the eaves girder 1c and the top of the longitudinal member 2, the male part 6 faces upward and the female part 5 faces downward. Therefore, even if the bag-filled adhesive 7 is put into the female part 5, it falls. Therefore, as shown in FIG. 6, an adhesive layer 10 may be formed on one surface of the bag 8, and the adhesive layer 10 may be attached to the back of the female portion 5. The adhesive layer 10 of the bag 8 can be easily implemented by using a well-known double-sided tape.

上記第一の接合構造は、縦用材２と横用材１を直交させて接合するいわゆる「仕口」について説明したが、図７，８に示したように、例えば同種の横用材１，１同士を継ぎ足す「継手」の場合も同様である。図示した継手は、周知の腰掛け鎌継ぎであり、この場合も雌部５に袋詰めの接着剤７をその長さに応じて２個並べて設置し、そこに雄部６を嵌合する。そうすると袋８が破裂し押し出された接着剤７が雄部６と雌部５の嵌合部に圧入される。なお、この継手の例で明らかなように雌部６は、少なくとも雄部６の差し込み方向に対して非貫通であればよい。   In the first joining structure described above, the so-called “joint” in which the longitudinal member 2 and the transverse member 1 are joined orthogonally, as shown in FIGS. The same applies to the “joint” in which The illustrated joint is a known stool sickle joint. In this case as well, two adhesives 7 in a bag are placed side by side on the female portion 5 according to the length thereof, and the male portion 6 is fitted therein. Then, the adhesive 7 ruptured and pushed out of the bag 8 is pressed into the fitting portion between the male portion 6 and the female portion 5. As is clear from the example of the joint, the female portion 6 may be non-penetrating at least with respect to the insertion direction of the male portion 6.

前記横用材１と縦用材２の第二の接合構造は、図３〜図５に示したように、直角に突き合わさる２つの取付片１１，１１と、その取付片１１，１１の端同士を連結する補強斜片１２とにより直角二等辺三角形とした固定金具１３を使用する。なお、実施形態では補強斜片１２の内側にそれと平行に小さい補強斜片１２が１本設けてある。   As shown in FIGS. 3 to 5, the second joining structure of the horizontal member 1 and the vertical member 2 includes two attachment pieces 11 and 11 that face each other at right angles, and ends of the attachment pieces 11 and 11. A fixing bracket 13 having a right-angled isosceles triangle is used by the reinforcing oblique piece 12 to be connected. In the embodiment, one small reinforcing oblique piece 12 is provided inside the reinforcing oblique piece 12 in parallel therewith.

前記固定金具１３の取付片１１，１１と補強斜片１２，１２は、断面Ｌ型の金属フレームで作られており、各部材同士が溶接等の固着手段で連結されている。各取付片１１，１１には横用材１と縦用材２にボルトや木ねじを通すための貫通孔１４，１４…が穿設されており、また、補強斜片１２，１２にもボルトや木ねじを通すための透孔１５，１５…が穿設されている。固定金具１３の大きさは、１つの取付片１１の長さが約７９ｃｍである。   The mounting pieces 11 and 11 and the reinforcing oblique pieces 12 and 12 of the fixing metal 13 are made of a metal frame having an L-shaped cross section, and the members are connected to each other by fixing means such as welding. Each mounting piece 11, 11 has a through hole 14, 14... For passing bolts and wood screws through the horizontal member 1 and the vertical member 2, and bolts and wood screws are also provided in the reinforcing slant pieces 12, 12. Through holes 15, 15... For passing are formed. As for the size of the fixture 13, the length of one mounting piece 11 is about 79 cm.

以上の構成である固定金具１３は、図３，図４に示したように、縦用材２と横用材１の直角をなすコーナー部にあてがい、固定金具１３の１つの取付片１１を縦用材２にボルト１６又は木ねじで固着し、また、固定金具１３の他の取付片１１を横用材１に同様に固着する。固定金具１３は、横用材１と主要な縦用材２の１つの接合部に対し１個又は２個取り付ける。すなわち１本の縦用材２に対し２本の横用材１，１が繋がるポイントには夫々の横用材１，１に対して２個の固定金具１３，１３を使用し、１本の縦用材２に対して１本の横用材１が繋がるポイントには１個の固定金具１３を使用する。固定金具１３は縦用材２の頂部に対しても逆さにした向きで使用する。   As shown in FIGS. 3 and 4, the fixing bracket 13 having the above configuration is applied to a corner portion that forms a right angle between the vertical member 2 and the horizontal member 1, and one mounting piece 11 of the fixing bracket 13 is attached to the vertical member 2. The other fixing piece 11 is fixed to the transverse member 1 in the same manner. One or two fixing brackets 13 are attached to one joint portion of the horizontal member 1 and the main vertical member 2. That is, at the point where two horizontal members 1, 1 are connected to one vertical member 2, two fixing brackets 13, 13 are used for each horizontal member 1, 1, and one vertical member 2 is used. On the other hand, one fixing bracket 13 is used at a point where one horizontal member 1 is connected. The fixing bracket 13 is used in an inverted direction with respect to the top of the vertical member 2.

こうして縦用材２と横用材１のコーナー部に固定金具１３，１３…を取り付けてしっかり固定することにより縦用材２が正確な垂直になるため、従来の仮筋止め等をしなくとも歪みのない軸組みが簡単・迅速に出来上がる。   In this way, the fixing members 13, 13... Are attached and firmly fixed to the corner portions of the vertical member 2 and the horizontal member 1 so that the vertical member 2 becomes an accurate vertical, so that there is no distortion even if the conventional temporary bracing is not performed. The shaft assembly is completed easily and quickly.

しかして前記第一の接合構造と上記第二の接合構造を適宜に組み合わせて軸組みを形成することにより、精度と強度に優れた建物が実現できる。例えば、建築用材同士の全てに第一の接合構造を採用し、主要な接合部を固定金具１３，１３…で固定するようにすれば、最も高強度の建物ができる。
一方、固定金具１３，１３…で固定した接合部以外の接合部に接着剤７による第一の接合構造を適用するだけでも実用上十分な強度が実現できる。
また、第一の接合構造を建物の一部に適用するだけでも十分に利用価値がある。
なお、固定金具１３の補強斜片１２，１２の透孔１５，１５…を利用すれば縦用材２，２間に筋交い４を設けることも可能である。そのため補強斜片１２の透孔１５，１５…は、異なる角度の筋交い４に対応するよう複数設けてある。 Therefore, a building having excellent accuracy and strength can be realized by appropriately combining the first joining structure and the second joining structure to form a shaft assembly. For example, if the first joint structure is adopted for all the building materials and the main joints are fixed by the fixtures 13, 13,..., The highest strength building can be obtained.
On the other hand, a practically sufficient strength can be realized only by applying the first joint structure by the adhesive 7 to the joints other than the joints fixed by the fixing metal fixtures 13, 13.
Moreover, even if the first joint structure is applied to a part of a building, it is sufficiently useful.
If the through holes 15, 15... Of the reinforcing slant pieces 12, 12 of the fixing metal 13 are used, it is possible to provide the bracing 4 between the longitudinal members 2, 2. Therefore, a plurality of through holes 15, 15... Of the reinforcing oblique piece 12 are provided so as to correspond to the braces 4 at different angles.

以上本発明を実施の形態について説明したが、もちろん本発明は上記実施形態に限定されるものではない。例えば、実施形態では袋８の周縁を溶着するようにしたが、袋８の破裂が可能であるなら溶着部８ｃの位置は限定されない。また、実施形態では袋８の破裂が溶着部８ｃから起こるようになっているが、溶着部８ｃの強度を高めて溶着部８ｃ以外の部分から破裂させるようにしてもよい。
また、実施形態に示したホゾとホゾ穴や腰掛け鎌継ぎは、「仕口」や「継手」の例示であって、それ以外の「仕口」や「継手」にも適用可能である。例えば「仕口」の一態様である周知の「だぼ」や、「継手」の一態様である「蟻継ぎ」などにも適用可能である。
また、実施形態では固定金具１３の補強斜片１２，１２を２本としたが、それ以上の複数本であっても、逆に１本であってもよい。もっとも補強斜片１２を複数本にした場合には、前記した筋交い４がしっかり固定できる効果がある。
なお、図面の雄部６と雌部５の隙間や袋基材８ａ，８ｂの厚み等は、説明の便宜に基づき実際より誇張して描かれている。 The embodiments of the present invention have been described above, but the present invention is of course not limited to the above embodiments. For example, although the periphery of the bag 8 is welded in the embodiment, the position of the welded portion 8c is not limited as long as the bag 8 can be ruptured. In the embodiment, the bag 8 is ruptured from the welded portion 8c. However, the strength of the welded portion 8c may be increased to rupture from a portion other than the welded portion 8c.
Further, the tenon, the tenon hole and the seat sickle joint shown in the embodiment are examples of “joint” and “joint”, and can be applied to other “joints” and “joints”. For example, the present invention can also be applied to the well-known “Dabo” that is one mode of the “joint” and “ant joint” that is one mode of the “joint”.
Further, in the embodiment, the two reinforcing slant pieces 12 and 12 of the fixing metal 13 are used. However, a plurality of reinforcing slant pieces 12 or 12 may be used, or one may be used. However, when a plurality of reinforcing slant pieces 12 are used, there is an effect that the bracing 4 described above can be firmly fixed.
In addition, the gap between the male part 6 and the female part 5 in the drawing, the thicknesses of the bag base materials 8a and 8b, and the like are exaggerated from the actuality for convenience of explanation.

本発明の第一の接合構造の効果を立証するため、次のような強度試験を行った。
［強度試験１］
断面正方形で一辺が100ｍｍの桧の角材を横用材１と縦用材２とした。そして、図１のように縦用材２に高さ約４０ｍｍ、幅約３０ｍｍの雄部６（短ホゾ）を形成すると共に横用材１にその雄部６が嵌合する非貫通の雌部５（ホゾ穴）を形成した。一方、木工用ボンドである接着剤７をビニール製の袋８に２２ｇ充填し、それを前記雌部５の底に置いて縦用材２の雄部６を嵌合した。その結果、雌部５と雄部６の境界部から接着剤７が僅かに溢れ出た。これにより雌部５と雄部６の嵌合部に対する接着剤７の圧入が確認された。この状態で接着剤７が硬化するまで３時間以上放置し、縦用材２の側面（横用材１から１５０ｍｍの高さ）に横用材１と平行な向きに荷重Ｆ１（図１参照）を加え、耐え得る最大荷重を測定した。
その結果、７１６Ｋｇｆの荷重に耐え得る強度が確認された。
［強度試験２］
断面正方形で一辺が100ｍｍの桧の角材を２本横用材１，１とした。そして、各横用材１，１の端部に図７に示した腰掛け鎌継ぎを構成する雄部６と雌部５を形成した。そして、雌部５に強度試験１と同じ大きさの袋詰め接着剤７を２つ並べ、その雌部５に雄部６を嵌めて接着剤７が硬化するまで３時間以上放置した。こうして繋がった横用材１，１を２点で支持（支点間距離＝５００ｍｍ）させ、支点間のほぼ中心にある鎌継ぎ部（細長い首部と台形の頭部の境界部）に荷重Ｆ２（図７参照）を加えて耐え得る最大荷重を測定した。
その結果、１０３３Ｋｇｆの荷重に耐え得る強度が確認された。 In order to verify the effect of the first joint structure of the present invention, the following strength test was performed.
[Strength test 1]
Square bars having a square cross section and a side of 100 mm were used as horizontal members 1 and vertical members 2. Then, as shown in FIG. 1, a male part 6 (short hozo) having a height of about 40 mm and a width of about 30 mm is formed on the vertical member 2 and the non-penetrating female part 5 (the male part 6 is fitted to the horizontal member 1). A side hole was formed. On the other hand, 22 g of the adhesive 7 as a woodworking bond was filled in a vinyl bag 8 and placed on the bottom of the female part 5 to fit the male part 6 of the longitudinal member 2. As a result, the adhesive 7 slightly overflowed from the boundary between the female part 5 and the male part 6. Thereby, press-fitting of the adhesive 7 into the fitting portion between the female portion 5 and the male portion 6 was confirmed. In this state, it is allowed to stand for 3 hours or more until the adhesive 7 is cured, and a load F1 (see FIG. 1) is applied to the side surface of the longitudinal member 2 (height from the transverse member 1 to 150 mm) in a direction parallel to the transverse member 1. The maximum load that could be tolerated was measured.
As a result, the strength capable of withstanding a load of 716 kgf was confirmed.
[Strength test 2]
Two square bars having a square cross section and a side of 100 mm were used as the horizontal members 1 and 1. And the male part 6 and the female part 5 which comprise the seat sickle joint shown in FIG. 7 at the edge part of each horizontal member 1 and 1 were formed. Then, two bag-packing adhesives 7 having the same size as the strength test 1 were arranged on the female part 5, and the male part 6 was fitted on the female part 5 and left for 3 hours or more until the adhesive 7 was cured. The transverse members 1 and 1 thus connected are supported at two points (distance between fulcrums = 500 mm), and a load F2 (FIG. 7) is applied to a sickle joint (boundary portion between the elongated neck and the trapezoidal head) at the substantial center between the fulcrums. The maximum load that can be withstood was measured.
As a result, the strength capable of withstanding a load of 1033 kgf was confirmed.
