Description
本発明は木造住宅の縦桁と横桁等の梁を連結し補強する木造住宅用補強金物に関する。
BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a reinforcing hardware for a wooden house, which connects and reinforces beams of longitudinal beams and horizontal beams of the wooden house.
従来、縦桁と横桁を連結し補強する木造住宅用補強金物としては、一般的に羽子板ボルトと呼ばれる金物が知られている。この補強金物は、金属製の羽子板にボルトが固定的に取り付けられたものであり、このような羽子板ボルトでは、住宅建設後に増し締め等をしようとしても、羽子板ボルト側からボルトを回転させることができず、ナットは外側（外壁の中）に位置してしまっているため、増し締め等ができないという欠点があった。
また、住宅を解体する場合に、縦桁と横桁が羽子板ボルトで接続されているため、縦桁と横桁の結合を容易に解除できず、羽子板ボルト等を破壊しなければ木材の接合部分を解体することができなかった。 Heretofore, as a reinforcing material for wooden houses which connects and reinforces a longitudinal girder and a transverse girder, a metal item generally referred to as a wingboard plate bolt is known. The reinforcing hardware is a bolt fixedly attached to a metal wing plate. With such a wing plate bolt, the bolt may be rotated from the wing plate bolt side even if it is intended to be tightened after construction of a house. Since the nut can not be located on the outer side (inside the outer wall), there is a drawback that it can not be tightened again.
In addition, when disassembling a house, since the longitudinal girder and the transverse girder are connected by the wing plate bolt, the connection between the longitudinal girder and the transverse girder can not be easily released. Could not dismantle.
また、住宅を解体する場合に、縦桁と横桁が羽子板ボルトで接続されているため、縦桁と横桁の結合を容易に解除できず、羽子板ボルト等を破壊しなければ木材の接合部分を解体することができなかった。 Heretofore, as a reinforcing material for wooden houses which connects and reinforces a longitudinal girder and a transverse girder, a metal item generally referred to as a wingboard plate bolt is known. The reinforcing hardware is a bolt fixedly attached to a metal wing plate. With such a wing plate bolt, the bolt may be rotated from the wing plate bolt side even if it is intended to be tightened after construction of a house. Since the nut can not be located on the outer side (inside the outer wall), there is a drawback that it can not be tightened again.
In addition, when disassembling a house, since the longitudinal girder and the transverse girder are connected by the wing plate bolt, the connection between the longitudinal girder and the transverse girder can not be easily released. Could not dismantle.
ボルトが羽子板に固定されていないものについては、例えば「一端部にボルトが着脱可能あるいは固定的に取付けられた羽子板本体と、この羽子板本体の他端部寄りの部位に形成された対向する部位に切欠部が形成されたボルト挿入孔と、このボルト挿入孔に挿入される頭部寄りの部位のボルト本体部位に打ち込みにより回動するように柱等の木材に食い込み、該ボルト挿入孔の切欠部と対応する部位に形成された食い込み片を有するボルトとを備えることを特徴とする羽子板」（特許文献１）が知られている。
For those whose bolts are not fixed to the feathered board, for example, “a feathered board main body to which a bolt is detachably or fixedly attached at one end, and a facing portion formed at a site near the other end of this feathered board main body A bolt such as a pillar bites into a bolt insertion hole in which a notch is formed and a bolt main body at a position near the head inserted into the bolt insertion hole, and cuts into the wood of the bolt insertion hole And a bolt having a bite formed at a corresponding portion is known as a "battle plate" (Patent Document 1).
しかし、このような羽子板についても、ボルト自体を回転させることができず、ナットは外側（外壁の中）に位置してしまっているため、増し締め等ができないという欠点があった。
However, even with such a wing plate, the bolt itself can not be rotated, and the nut is located outside (in the outer wall), so that there is a drawback that retightening and the like can not be performed.
ところで、食い込み片が無いものを用いた場合には、ボルトを回転させることはできるものの、ナットが空転してしまうおそれがあり、確実に増し締めをすることができず、住宅解体時にも、ナットが空転することにより、分解することができずボルト等を破壊しなければならないおそれがあった。
By the way, although the bolt can be rotated when there is no bite bit, there is a possibility that the nut may be idled, and it can not be securely tightened and the nut can be dismantled even when the house is dismantled. As a result, there was a risk that the bolt could not be disassembled because it could not be disassembled.
本発明は以上のような従来の欠点に鑑み、容易かつ確実に増し締めをすることができ、解体時には容易に分解できる木造住宅用補強金物を提供することを目的としている。

In the present embodiment, the first screwing portion 5 of the bolt 7 is formed as a left screw, and the second screwing portion 6 is formed as a right screw. By forming in this manner, retightening can be performed simply by turning the bolt 7 in one direction.
なお、第１螺合部５と第２螺合部６が逆回しのネジになればよいので、第１螺合部５を右ネジ、第２螺合部６を左ネジとしてもよい。
In addition, since the first screwing portion 5 and the second screwing portion 6 only need to be a reverse screw, the first screwing portion 5 may be a right screw and the second screwing portion 6 may be a left screw.
ナット部材８は、本実施形態ではナットセグメント収納部１２を単数又は複数個、本実施形態では３つ有するナット本体１３と、ナットセグメント収納部１２に収納された複数個、本実施形態では３つのナットセグメント収納部１２にそれぞれ収納される３つのナットセグメント１４と、該ナットセグメント１４の上方に設けられ、ナットセグメント１４をナット本体１３の底面方向へ付勢する付勢手段１５と、前記ナットセグメント１４及び付勢手段１５（例えば付勢スプリング）を前記ナット本体１３内部に保持する保持手段１６と、前記ナット本体１３の下端部に設けられた座金部材１７とで構成されている。
このナット部材８のナットセグメント１４は前記第２螺合部６と螺合するように形成されている。 Thenut member 8 has a nut body 13 having one or a plurality of nut segment storage portions 12 in the present embodiment, three in the present embodiment, and a plurality of the nut segment storage portions 12 stored in the nut segment storage portion 12. Three nut segments 14 respectively stored in the nut segment storage portion 12, biasing means 15 provided above the nut segments 14 for biasing the nut segments 14 in the direction of the bottom surface of the nut body 13, and the nut segments A holding means 16 for holding 14 and biasing means 15 (for example, biasing spring) inside the nut body 13 and a washer member 17 provided at the lower end portion of the nut body 13.
Thenut segment 14 of the nut member 8 is formed to be screwed with the second screwing portion 6.
このナット部材８のナットセグメント１４は前記第２螺合部６と螺合するように形成されている。 The
The
前記保持手段１６は、本実施形態では、ナット本体１３の上端部をカシメにより内側に折り曲げてワッシャーを係止し、ナットセグメント１４及び付勢手段１５を前記ナット本体１３内部に保持している。この保持手段１６は、例えば、ナット本体１３の上部付近の外周面にネジを形成し、このネジに袋ナット状の蓋体を螺合させてナットセグメント１４及び付勢手段１５を前記ナット本体１３内部に保持するようにしてもよい。
In the present embodiment, the holding means 16 bends the upper end portion of the nut body 13 inward by caulking to lock the washer, and holds the nut segment 14 and the biasing means 15 inside the nut body 13. The holding means 16 forms, for example, a screw on the outer peripheral surface near the upper portion of the nut body 13, and a cap-nut-like lid is screwed to the screw to make the nut segment 14 and the biasing means 15 the nut body 13. You may hold it inside.
座金部材１７は本実施形態ではナット本体１３に回転可能に設けられており、座金部材１７の底面には複数個の爪１８が形成されている。この爪１８によってナット部材８を木材に取り付ける。
In the present embodiment, the washer member 17 is rotatably provided on the nut body 13, and a plurality of claws 18 are formed on the bottom surface of the washer member 17. The nut member 8 is attached to the wood by the claws 18.
なお、ナット部材８として、公知のナットセグメントを用いたナットを使用することができる。
A nut using a known nut segment can be used as the nut member 8.
本発明の補強金物１を使用し、増し締めを行う場合には、図６に示すように、工具係合部１１に例えばドライバーの先端部を係合し、ボルト７を回転させる。第１螺合部５と第２螺合部６は逆回りのネジに形成されているので、螺合部２及びナット部材８を同時に締め付けることができる。
In the case of using the reinforcing metal fitting 1 of the present invention and retightening, as shown in FIG. 6, for example, the tip end portion of a driver is engaged with the tool engaging portion 11, and the bolt 7 is rotated. Since the first screwing portion 5 and the second screwing portion 6 are formed in reverse rotation, the screwing portion 2 and the nut member 8 can be tightened simultaneously.
解体を行う際には、増し締めした時とは逆方向にボルトを回転させることにより、ナット部材８側ではボルト７の回転により羽子板ナット４側（内側）へボルト７が移動しようとするものの、羽子板ナット４側もナット部材８側（内側）へ移動しようとするので、螺合部２及びナット部材８は軸方向の力を受ける。そうすると、ナットセグメント１４はこの力により押圧されて付勢手段１５の付勢力に抗して外側へ移動し、ナット部材８の内径が拡大する。これにより羽子板ナット４の螺合部２から第１螺合部５が外れる方向（ナット部材側）に移動し、補助金具１を分解することができる。
When disassembling, by rotating the bolt in the direction opposite to the direction of retightening, the bolt 7 tries to move to the wing plate nut 4 side (inside) by the rotation of the bolt 7 on the nut member 8 side, Since the wing plate nut 4 side also tries to move to the nut member 8 side (inside), the screwing portion 2 and the nut member 8 receive an axial force. Then, the nut segment 14 is pressed by this force and moves outward against the biasing force of the biasing means 15, and the inner diameter of the nut member 8 is expanded. As a result, the auxiliary fitting 1 can be disassembled by moving in a direction (nut member side) in which the first screwing portion 5 is disengaged from the screwing portion 2 of the wing plate nut 4.
