Description

本発明は、木造住宅において、構造材どうしを接合するための接合金物に関するものである。 The present invention relates to a metal fitting for joining structural members together in a wooden house.

近年、木造軸組工法の構造材どうしの接合部、特に柱と梁との接合部において、構造材端部の加工の簡略化及び接合部の強化のために、接合金物を介して構造材どうしを接合する、金物工法が用いられている。
金物工法は、工場で接合金物を一方の構造材（例えば柱）に取り付けて建築現場に搬入し、同じく工場で端部加工を行ったもう一方の構造材（例えば梁）を現場にて接合する。 In recent years, in order to simplify the processing of the ends of structural members and strengthen the joints at the joints between structural members of the wooden frame construction method, especially the joints between columns and beams, the structural members are joined together. The metal construction method is used to join the two.
In the hardware construction method, a joint hardware is attached to one structural material (for example, a pillar) at a factory, and then transported to a construction site. Another structural material (for example, a beam) that has been subjected to end processing at the factory is also joined on the site. .

しかし、従来の接合金物を用いた金物工法には、以下の問題があった。
（１）従来の接合金物は、ボルト孔に通したボルトのせん断耐力が構造体の耐力と大きく関わるため、木材の木やせなどから生じるボルトの弛みによって接合部強度が低下してしまう。
（２）同様に、せん断耐力を有する「あご掛け」がある場合でもボルトの弛みによってその効果は失われ、接合部強度は低下してしまう。
（３）梁側に２つのスリットを設けて接合する金物工法用金物の場合、金物の板厚および接合用ボルト頭部(またはナット)が受け材から突出し、その干渉を防ぐため梁側仕口中央部に欠き込みを設けなければならない。
（４）予め工場で接合金物を取り付けて現場に搬入するが、接合金物は構造材から突出しているため、運搬の際に接合金物を養生する必要があり、荷かさが増して運搬費が増大してしまう。 However, the conventional hardware method using the joint hardware has the following problems.
(1) In conventional joint hardware, since the shear strength of the bolts passed through the bolt holes is greatly related to the strength of the structure, the joint strength decreases due to loosening of the bolts caused by wood thinning or the like.
(2) Similarly, even when there is a “chin hook” having shear strength, the effect is lost due to the loosening of the bolt, and the joint strength is reduced.
(3) In the case of hardware for hardware construction, which is provided with two slits on the beam side, the thickness of the hardware and the bolt head (or nut) for the projection protrude from the receiving material, and the beam side joint is used to prevent interference. A notch must be provided in the center.
(4) Attach joint hardware in the factory in advance and carry it to the site. However, since the joint hardware protrudes from the structural material, it is necessary to cure the joint hardware during transportation, increasing the bulk and increasing transportation costs. Resulting in.

本発明は、分割することにより、構造材からの突出部分を無くして運搬を容易にすると共に、構造材どうしを容易に高強度に接合することができる、接合金物を提供することを目的とする。 An object of the present invention is to provide a metal joint that can be easily transported by eliminating a protruding portion from a structural material by dividing, and can easily join the structural materials to each other with high strength. .

The locking portion 22 extends from the insertion portion 21 with a size that can be inserted into the locking hole 11.
The locking portion 22 is provided with a locking groove 221 having the same width as the thickness of the receiving seat 1 along the insertion portion 21.

（３）固定片
係止部材２の挿入部２１の係止部２２側の端部には、延設する係止部２２に直交するように、固定片２１２を設ける。
固定片２１２は、係止部２２の係止溝２２１と対向するように立設する。
固定片２１２の長さは、係止溝２２１の底２２１ｂから固定片２１２の突端までの長さが、受け座１の係止孔１１の長さとほぼ同一となるようにする。
また、固定片２１２は、ハンマー等で打撃することにより塑性変形し、係止部２２側へ折曲可能とする。 (3) Fixed piece The fixed piece 212 is provided in the edge part by the side of the latching | locking part 22 of the insertion part 21 of the latching member 2 so that it may orthogonally cross the latching | locking part 22 extended.

Further, the locking groove 221 is fitted to the receiving seat 1, and the bottom portion 221 b of the locking groove 221 is in contact with the lower end of the locking hole 11.
Therefore, when the fixed piece 212 is driven into the locking hole 11, the upper end of the fixed piece 212 comes into contact with the upper end of the locking hole 11, and the upward sliding of the locking member 2 is restricted, and the receiving seat 1 and the locking member 2 Is integrated without rattling, and the locking member 2 can be prevented from falling off.

［２］接合構造
次に本発明の接合金物を用いた、構造材の接合構造について説明する。
構造材は木材であり、木造住宅の梁や柱などの部材である。 [2] Joining structure Next, a joining structure of structural members using the joining hardware of the present invention will be described.
The structural material is wood, and is a member such as a beam or a column of a wooden house.

（１）受け座の取り付け
受け座１は構造材３ａに設けた受け座嵌合穴３１に嵌合し、スクリューねじ４により固定する。（図３）
受け座１は板体であるため、構造材３ａとの接触面積が大きい。このため、ボルト及びナットにより背面から支持する必要が無く、表面からねじ孔１２にスクリューねじ４を緊合することにより、受け座１を構造材３ａに強固に固定することができる。また、ボルト及びナットにより背面から支持する必要がないため、構造材３ａの切削量を少なくでき、構造材３ａの強度を維持することができ、ボルト及びナットの弛みによる接合強度の低下も生じない。
受け座１を受け座嵌合穴３１に嵌合することにより、受け座１が構造材３ａから突出しない。これにより、工場で予め受け座１を取り付けた構造材３ａを現場に搬入する場合であっても、突出する部分を養生する必要がなく、荷かさを抑えて運搬費を節減することができる。
また、構造材３ａには突出部分がないため、現場での組み立ても容易となる。
受け座嵌合穴３１の底面には、受け座１の係止孔１１に対応する位置に、予め係止孔１１とほぼ同幅であるスリット状の係止穴３１１を設けておく。そして受け座１を受け座嵌合穴３１に嵌合することにより、受け座１の係止孔１１と係止穴３１１が連通する。
係止穴３１１は係止部材２の係止部２２がスライドできるように、係止孔１１よりも下方に長く形成する。 (1) Attaching the receiving seat The receiving seat 1 is fitted into the receiving seat fitting hole 31 provided in the structural member 3 a and fixed by the screw 4. (Figure 3)
Since the receiving seat 1 is a plate, the contact area with the structural material 3a is large. For this reason, it is not necessary to support from the back by a bolt and a nut, and the receiving seat 1 can be firmly fixed to the structural material 3a by fastening the screw screw 4 to the screw hole 12 from the surface. Moreover, since it is not necessary to support from the back surface with a bolt and a nut, the cutting amount of the structural material 3a can be reduced, the strength of the structural material 3a can be maintained, and the joint strength is not reduced due to loosening of the bolt and nut. .
By fitting the receiving seat 1 into the receiving seat fitting hole 31, the receiving seat 1 does not protrude from the structural material 3a. Thereby, even if it is a case where the structural material 3a which attached the receptacle 1 beforehand in the factory is carried in to the field, it is not necessary to cure the protruding part, and it can suppress a bulk and can reduce transportation cost.
Moreover, since the structural member 3a has no protruding portion, it is easy to assemble on site.
A slit-like locking hole 311 having a width substantially the same as that of the locking hole 11 is provided in advance on the bottom surface of the receiving seat fitting hole 31 at a position corresponding to the locking hole 11 of the receiving seat 1. Then, by engaging the receiving seat 1 with the receiving seat fitting hole 31, the locking hole 11 and the locking hole 311 of the receiving seat 1 communicate with each other.
The locking hole 311 is formed longer than the locking hole 11 so that the locking portion 22 of the locking member 2 can slide.

（２）係止部材の係止
係止部材２の係止部２２を、連通する受け座１の係止孔１１及び係止穴３１１に挿入して係合する。（図４）
そして、係止部材２を下方にスライドし、係止溝２２１と受け座１を嵌合することにより、受け座１と係止部材２とを一体とする。
係止部材２は板状の部材であるため、取り扱いが容易である。また、係止部材２を挿入してスライドするだけで一体となるため、現場においても容易に係止作業を行うことができる。 (2) Locking of the locking member The locking portion 22 of the locking member 2 is inserted into and engaged with the locking hole 11 and the locking hole 311 of the receiving seat 1 that communicates. (Fig. 4)
Then, by sliding the locking member 2 downward and fitting the locking groove 221 and the receiving seat 1, the receiving seat 1 and the locking member 2 are integrated.
Since the locking member 2 is a plate-like member, handling is easy. Moreover, since it is united only by inserting and sliding the latching member 2, a latching operation can be easily performed also in the field.

（３）構造材の接合
係止部材２の固定片２１２を、ハンマー等により係止孔１１に打ち込み、固定片２１２の上端を係止孔１１の上端に接触させて、係止部材２が上方にスライドして受け座１から脱落するのを防ぐ。（図５）
また、固定片２１２の上端と係止孔１１の上端が接触するため、受け座１を設けた構造材３ａに対してがたつくことがない。
そして、構造材３ｂに予め設けたスリット３２に係止部材２の挿入部２１を挿入し、構造材３ｂの側面からドリフトピン５を貫入してピン穴２１１に挿通して、係止部材２と構造材３ｂを連結する。連結にボルト及びナットを使用しないため、構造材にボルト及びナットの突出による干渉を防ぐための欠き込みを設ける必要が無く、構造材の強度を維持できる。
これにより、接合金物を介して構造材３ａ、３ｂが接合される。
構造材３ｂを連結する係止部材２が構造材３ａに対してがたつくことがないため、構造材３ａ，３ｂどうしもがたつくことがない。 (3) Joining of structural materials The fixing piece 212 of the locking member 2 is driven into the locking hole 11 with a hammer or the like, the upper end of the fixing piece 212 is brought into contact with the upper end of the locking hole 11, and the locking member 2 is moved upward. To prevent it from falling off the seat 1. (Fig. 5)
Further, since the upper end of the fixed piece 212 and the upper end of the locking hole 11 are in contact with each other, the structure member 3a provided with the receiving seat 1 is not rattled.
Then, the insertion portion 21 of the locking member 2 is inserted into the slit 32 provided in advance in the structural material 3b, the drift pin 5 is inserted from the side surface of the structural material 3b, and is inserted into the pin hole 211. The structural material 3b is connected. Since bolts and nuts are not used for connection, it is not necessary to provide notches in the structural material to prevent interference due to protrusions of the bolts and nuts, and the strength of the structural material can be maintained.
Thereby, the structural materials 3a and 3b are joined via the joining hardware.
Since the locking member 2 that connects the structural material 3b does not rattle against the structural material 3a, the structural materials 3a and 3b do not rattle.

［その他実施例］
本発明の接合金物は、受け座１と係止部材２とを一組として、複数組を組み合わせる事により、様々な大きさの構造材や、接合部分に用いることができる。（図６）
複数の接合金物を組み合わせて使用する場合には、接合箇所となる係止溝２２１や固定片２１２が複数存在するため、従来の大型の接合金物を使用する場合と比べて、より強固に固定することができ、緩みが生じることもない。 [Other Examples]
