Description

【０００１】
【産業上の利用分野】
本発明は、概し、管柱と桁との接合に際して用いる木造軸組構造における柱と横架材の接合装置に関するものである。
【０００２】
【従来の技術】
柱と桁との横架材を接合するには、横架材側に設けたほぞ穴に、柱側に設けたほぞを挿着して構成する所謂ほぞ接合が一般に用いられている。
【０００３】
【発明が解決しようとする課題】
前記従来例は、地震などの外力の負荷により当該ほぞ接合部が容易に緩み、このため、別途補強金具を両材間に止着する必要がある等の欠点がある。
【０００４】
本発明は、従来のほぞ接合に代る、しかも、接合強度上優れた装置を提供することを目的として創案したものである。
【０００５】
【課題を解決するための手段】
柱の上端面との間に隙間が形成されるように、該柱に嵌挿して止着した接合杆に、前記柱に載置した横架材を通じて締付け杆を螺合して互いに接続し、該締付け杆の緊締部片を、前記横架材に止着した構成とする。
【０００６】
【実施例】
図面は本発明に係る柱と横架材の接合装置の一実施例を示し、図１は縦断面図、図２は主要部材の斜視図である。
【０００７】
本発明は、接合杆１と締付け杆２を用い、柱３と該柱３上に載置した桁などの横架材４を互いに接合するために適用し、接合杆１は円筒状の主体５の上端（一端）部に雌螺子１ａを設け、周側の中間部に、接合杆１の長手（上下）方向に隣接するもの同志を互いに直交する方向に配するようにして透孔６，…を設けて構成したものである。
【０００８】
この接合杆１は、前記柱３の上端面３´を開口して形成した縦穴７に前記雌螺子１ａを上側にして嵌挿し、前記縦穴７に直交させて前記柱３に設けた貫通孔８に前記透孔６を一致させ、これら孔６，８にドリフトピン９を貫通させて前記柱１に止着したもので、この柱１との組付け状態にあって、柱上端面３´との間に隙間ａが形成されるように前記縦穴７に納められ（埋入され）ている。
【０００９】
なお、接合杆１は金属製の円筒体で構成するが、角筒でも差し支えなく、中実体で構成しても不都合はない。
【００１０】
柱１に対する止着手段としては、実施例ではドリフトピン９を用いているが、該ドリフトピン９に代えてボルト体を用い、これを貫通孔８および透孔６に貫通させ、貫通孔８より突出するボルト先端にナットを螺合するようにしても良い。
【００１１】
前記締付け杆２は、円板状の緊締部片１０の片面の中央に、先端側に雄螺子２ａを設けた主体杆部１１を突設し、緊締部片１０には透孔１２を設けて構成したものである。
【００１２】
しかして、接合杆１を組付けた前記柱３上に、貫通孔１３を接合杆１の雌螺子１ａに一致させるようにして横架材４を載置し、貫通孔１３を通じて締付け杆２の主体杆部１１の先端に設けた雄螺子２ａを接合杆１の雌螺子１ａに螺合締付け、横架材４を介して接合杆１に接続し、透孔１２を利用して緊締部片１０を釘１４で横架材４に止着することにより、柱３と横架材４は互いに接合される。
【００１３】
なお、接合杆１と締付け杆２との締付け時（柱３と横架材４との接合操作時）に、前記隙間ａの存在により、横架材４は柱３に引き寄せられ、両材４，３はより強固に接合される。
【００１４】
なお、接合杆１の上端を、横架材４内に位置させても支障はなく、この場合、接合杆１の上端と横架材４との間に前記の隙間ａに代る隙間を設けることにより、実施例と同様の引き寄せ操作を行うことができる。
【００１５】
もっとも、隙間ａは、接合杆１すなわち主体５の上端が締付け当初より横架材４に接触しての円滑な引き寄せ操作の障害を回避するためのものであるが、締付けにより前記の主体上端が横架材４の木材であるという材質により、該横架材４に嵌入することを考慮すれば、この隙間を省略しても、接合杆１と締付け杆２との螺合操作だけで引き寄せは行うことができる。
【００１６】
また、締付け杆２の緊締部片１０は、横架材４に形成した前記貫通孔１３を取り囲む凹入部１５に納めてあるが、この凹入部１５は省略しても良い。
【００１７】
【発明の効果】
本発明は前記の通りの構成であるから、締付け杆を接合杆に螺合締付けることにより、柱と横架材の接合を確実に行うことができると共に、柱と横架材は柱側を固定側として互いに引き寄せられるから、前記接合は強固に行われ、ほぞ接合に代る実用的な接合装置を提供できる。

[Industrial application fields]
The present invention generally relates to a joining device for a column and a horizontal member in a wooden frame structure used for joining a pipe column and a girder.
[0002]
[Prior art]
In order to join the horizontal members of the columns and girders, so-called tenon bonding is generally used in which a tenon provided on the column side is inserted into a tenon provided on the horizontal material side.
[0003]
[Problems to be solved by the invention]
The conventional example has a drawback that the tenon joint is easily loosened by an external force load such as an earthquake, so that it is necessary to separately attach a reinforcing bracket between the two members.
[0004]
The present invention was devised for the purpose of providing a device that replaces the conventional tenon joint and has excellent joint strength.
[0005]
[Means for Solving the Problems]
As the gap between the upper end face of the pillar is formed, the joining rod which is fastened to fitted to the column, and connected to each other screwed clamping rod through horizontal members placed on the said post, The tightening piece of the tightening rod is fixed to the horizontal member.
[0006]
【Example】
The drawings show an embodiment of a joining device for pillars and horizontal members according to the present invention, FIG. 1 is a longitudinal sectional view, and FIG. 2 is a perspective view of main members.
[0007]
The present invention is applied to use a joining rod 1 and a fastening rod 2 to join a column 3 and a horizontal member 4 such as a girder placed on the column 3 to each other. The joining rod 1 is a cylindrical main body 5. A female screw 1a is provided at the upper end (one end) of the through hole 6, and the adjacent ones in the longitudinal (up and down) direction of the joining rod 1 are arranged in a direction perpendicular to each other in the middle portion on the circumferential side. Is provided.
[0008]
The joint rod 1 is inserted into a vertical hole 7 formed by opening the upper end surface 3 ′ of the column 3 with the female screw 1 a facing upward, and a through hole 8 provided in the column 3 so as to be orthogonal to the vertical hole 7. The through holes 6 are made to coincide with each other, and the drift pins 9 are passed through the holes 6 and 8 and are fixed to the pillars 1 in the assembled state with the pillars 1. Is inserted (embedded) in the vertical hole 7 so that a gap a is formed between them.
[0009]
In addition, although the joining rod 1 is comprised with a metal cylinder, it does not interfere even if it may be a square tube, and there is no problem even if comprised with a solid body.
[0010]
As the fixing means for the column 1, the drift pin 9 is used in the embodiment, but a bolt body is used instead of the drift pin 9, and this is passed through the through hole 8 and the through hole 6. A nut may be screwed onto the protruding bolt tip.
[0011]
The fastening rod 2 has a main collar portion 11 provided with a male screw 2a on the front end side in the center of one surface of a disc-shaped fastening portion piece 10, and a through hole 12 is provided in the fastening portion piece 10. It is composed.
[0012]
Thus, the horizontal member 4 is placed on the column 3 to which the joining rod 1 is assembled so that the through hole 13 is aligned with the female screw 1 a of the joining rod 1. The male screw 2a provided at the tip of the main collar 11 is screwed and fastened to the female screw 1a of the joining rod 1, connected to the joining rod 1 through the horizontal member 4, and the tightening piece 10 using the through hole 12 is connected. Is fixed to the horizontal member 4 with the nail 14, so that the column 3 and the horizontal member 4 are joined to each other.
[0013]
When the joining rod 1 and the fastening rod 2 are tightened (when the column 3 and the horizontal member 4 are joined), the horizontal member 4 is attracted to the column 3 due to the presence of the gap a, and both members 4 , 3 are joined more firmly.
[0014]
In addition, there is no problem even if the upper end of the joining rod 1 is positioned in the horizontal member 4, and in this case, a gap is provided between the upper end of the joining rod 1 and the horizontal member 4 in place of the gap a. Thus, the same pulling operation as in the embodiment can be performed.
[0015]
However, the gap a is for avoiding obstacles in smooth pulling operation in which the upper end of the joint rod 1, that is, the main body 5 is in contact with the horizontal member 4 from the beginning of tightening. Taking into account the fact that the horizontal member 4 is made of wood, it can be pulled by only the screwing operation between the joint rod 1 and the tightening rod 2 even if this gap is omitted. It can be carried out.
[0016]
Further, the tightening piece 10 of the tightening rod 2 is housed in a recessed portion 15 surrounding the through hole 13 formed in the horizontal member 4, but the recessed portion 15 may be omitted.
[0017]
【The invention's effect】
Since the present invention is configured as described above, the column and the horizontal member can be reliably joined to each other by fixing the column and the horizontal member by screwing and tightening the tightening rod to the joint rod. Since they are attracted to each other as a side, the joining is performed firmly, and a practical joining device that replaces the tenon joining can be provided.
