Description

本発明は、木造住宅において、主として柱と横架材を緊結する引き寄せ金物に関する。   TECHNICAL FIELD The present invention relates to an attracting metal for mainly connecting a pillar and a horizontal member in a wooden house.

木造住宅、特に木造軸組み住宅では、柱と横架材のように直交して結合される第１の構造材と第２の構造材との結合部に引き寄せ金物やかど金物など、多くの補強金物を用いて耐震性を向上させている。しかし、このような金物が多く用いられるようになったのは、住宅の耐震性に関心が高まった最近のことであり、また、ほとんどが新築の際に用いることを前提とした金物である。
一方、既存の木造住宅では、補強金物を用いて耐震性を向上させる必要のあるものも多い。このような住宅の耐震補強にはホールダウン金物や羽子板金物のような引き寄せ金物を用いて柱と横架材を緊締することが有効である。 In wooden houses, especially wooden framed houses, many reinforcements such as metal fittings and metal fittings are drawn to the joint between the first structural material and the second structural material that are joined orthogonally, such as pillars and horizontal members. Seismic resistance is improved using hardware. However, such hardware has come to be used a lot recently because of interest in the earthquake resistance of houses, and most of them are hardware that is supposed to be used in new construction.
On the other hand, there are many existing wooden houses that need to be improved in earthquake resistance using reinforcing hardware. For the seismic reinforcement of such a house, it is effective to fasten the column and the horizontal member using a pull-down hardware such as a hole-down hardware or a feather metal sheet.

しかし、既存住宅の耐震補強は、居住中であることあって、できるだけ短期間に施工でき、且つ、低コストであることが望ましい。このため、建物の外壁を壊すなどの施工はせず、図１のように、室内側から内壁材を取り外して梁など横架材（１）と柱（２）の結合個所を露出させ、必要な施工をすることも多い。しかし、内壁を外しただけの状況で施工すると、天井材（３）が邪魔になって、施工は、外壁（４）との間のわずかな隙間（間柱（５）の幅寸法）から金物（６）や工具（７）を差し入れて行なわなければならない。   However, it is desirable that the seismic reinforcement of existing houses be resident and can be constructed in as short a time as possible and at a low cost. For this reason, construction such as breaking the outer wall of the building is not required, and as shown in Fig. 1, the inner wall material is removed from the indoor side to expose the joint of the horizontal member (1) and column (2) such as a beam. There are many cases where the construction is difficult. However, if the construction is performed with the inner wall removed, the ceiling material (3) becomes an obstacle, and the construction can be performed from a slight gap between the outer wall (4) (the width dimension of the stud (5)) and the hardware ( 6) and tools (7) must be inserted.

この作業は、作業個所を直視して行うのが困難なため、ほとんど盲作業に近いものとなる上、作業空間が狭く施工は困難を極める。特に柱に金物を固定するときのように、工具を横方向から操作する必要のあるときは片手の作業になってしまう（図２）。また、従来の引き寄せ金物や羽子板ボルトは、縦・横いずれか一方の構造材に貫通孔を設けてそこに引き寄せボルトを貫通させ、この引き寄せボルトの先端を突出側で構造材に固定するなどの作業が必要である。このような作業は、室内側からだけでは完了できない。結局、２階の床板を取り除くなどの作業が必要になる。   Since it is difficult to perform this work by directly looking at the work site, the work is almost a blind work, and the work space is narrow and construction is extremely difficult. Especially when it is necessary to operate the tool from the side, such as when fixing hardware to a pillar, it is a one-handed operation (FIG. 2). In addition, the conventional attracting hardware and wing plate bolts are provided with a through hole in either the vertical or horizontal structural material, through which the attracting bolt penetrates, and the tip of this attracting bolt is fixed to the structural material on the protruding side, etc. Work is necessary. Such work cannot be completed only from the indoor side. Eventually, work such as removing the floorboard on the second floor is necessary.

一方、引き寄せ金物には、引き寄せボルトの強い引き寄せ力でもボルトとの螺合部が破壊されてしまわないように十分な螺合寸法と、強い引き寄せ力でも変形を起こさない強度が必要である。
この発明は、補強金物として重要な引き寄せ金物について、室内側からだけの施工で取り付けることができ、且つ、作業がしやすく、また、ボルトが金物から抜けてしまったり、金物が変形したりしない、大きな引き抜き力に耐える引き寄せ金物の提供を課題とする。 On the other hand, the attracting metal needs to have a sufficient threading dimension and a strength that does not cause deformation even with a strong pulling force so that the screwed part with the bolt is not broken even by a strong pulling force of the pulling bolt.
This invention is an attracting metal that is important as a reinforcing hardware, can be attached by construction only from the indoor side, is easy to work, and the bolt does not come out of the hardware or the hardware does not deform, The challenge is to provide a metal fitting that can withstand a large pulling force.

木造住宅において直交する第１の構造材と第２の構造材を緊結するための引き寄せ金物であって、第１の構造材へ固定する第１の取付け金物と第２の構造材ヘ固定する第２の取り付け金物間を、これらに結合した引き寄せボルトで緊締する。
第１の構造材（例えば、梁，横架材）に取り付ける第１の取付け金物は、第２の構造材（例えば、柱）に対する固定部分を有しないものとし、下方から上方への作業だけで固定できるようにする。第１の取付け金物は上部材と下部材で構成し、上部材に下部材を突き当てて組み合わせる。組み合わせると、第１の取付け金物と第２の取付け金物は外形が厚みのある直方体部材を構成する。直方体構造は、引き寄せボルトの強い引き寄せ力による撓みを防止できる剛性を備えると共に直方体が有する厚みにより、引き寄せボルトと第１の取付け金物間に十分な螺合長さを設定することができる。これにより、第１の取り付け金物は、強い引き抜き力に耐えることができる。
引き寄せボルトの下部は第２の構造材に固定する第２の取付け金物に結合し、引きナットで緊締する。 An attracting hardware for binding a first structural material and a second structural material orthogonal to each other in a wooden house, the first mounting hardware fixed to the first structural material and the second structural material fixed to the second structural material The two mounting hardwares are tightened with pulling bolts connected to them.
The first mounting hardware to be attached to the first structural material (for example, a beam or a horizontal member) does not have a fixing portion for the second structural material (for example, a column), and only works from below to above. Allow to be fixed. The first mounting hardware is composed of an upper member and a lower member, and the lower member is abutted against the upper member and combined. When combined, the first mounting hardware and the second mounting hardware constitute a rectangular parallelepiped member having a thick outer shape. The rectangular parallelepiped structure has rigidity capable of preventing the pulling bolt from being bent due to the strong pulling force, and the thickness of the rectangular parallelepiped can set a sufficient screwing length between the pulling bolt and the first mounting hardware. Thereby, the first mounting hardware can withstand a strong pulling force.
The lower part of the pulling bolt is coupled to a second mounting hardware fixed to the second structural member, and tightened with a pulling nut.

外壁を取り外すことなく、屋内側から施工できるので、天候に左右されず、短期間に施工を完了できる。
第１の構造材に固定する第１の取付け金物は第２の構造材への取り付け部を有しないから、狭い空間で第１の構造材の下面に取付けるときでも、固定しやすい。このため，施工は内壁材を取り外す程度の小規模の解体ですみ、工事費を抑制することができる。
第１の取付け金物は直方体部材を備えるので、その剛性により、強い引き寄せ力によっても取付け金物が湾曲するなどの変形が生じない。また、直方体の厚みにより、十分な螺合寸法を持つから、強い引き寄せ力によっても引き寄せボルトが抜けてしまうことがない。 Since construction can be performed from the indoor side without removing the outer wall, construction can be completed in a short period of time regardless of the weather.
Since the first mounting hardware fixed to the first structural material does not have an attachment portion to the second structural material, it is easy to fix even when mounting to the lower surface of the first structural material in a narrow space. For this reason, the construction can be done with a small-scale dismantling that removes the inner wall material, and construction costs can be reduced.
Since the first mounting hardware includes a rectangular parallelepiped member, due to its rigidity, deformation such as bending of the mounting hardware does not occur even with a strong pulling force. Further, since the screw has a sufficient screw size due to the thickness of the rectangular parallelepiped, the pulling bolt does not come off even by a strong pulling force.

第１の構造材に固定する第１の取付け金物と、第２の構造材に固定する第２の取付け金物及びこれらを結合して緊締する引き寄せボルトと引きナットで構成する。
第１の取付け金物は、上部材と下部材及び止めナットで構成する。
上部材と下部材は、上部材に下部材を突き当てて組み合わせると直方体部材となる。直方体部材に上下方向の貫通孔とその周辺に固定用のネジを挿通するネジ挿通孔を形成しておく。直方体の内部に貫通孔の軸線にネジ孔を合わせて止めナットを位置決めしておく。
第１の構造材に第１の取付け金物を固定し、第２の構造材に第２の取付け金物を固定する。第２の取付け金物の係合部に下方から挿し込んだ引き寄せボルトの上部を直方体部材の下方から貫通孔に挿し込んで止めナットに螺合し、引き寄せボルトを直方体部材に取り付ける。引き寄せボルトの下部に引きナットを螺合してこれを第２の取付け金物に係合し、ついで、引きナットを緊締し、第１の取付け金物と第２の取付け金物間を引き寄せボルトにより緊結する。 The first mounting hardware fixed to the first structural material, the second mounting hardware fixed to the second structural material, and a drawing bolt and a pulling nut that are coupled and tightened together.
The first mounting hardware is composed of an upper member, a lower member, and a lock nut.
When the upper member and the lower member are combined by abutting the lower member against the upper member, they become a rectangular parallelepiped member. The rectangular parallelepiped member is formed with a through hole in the vertical direction and a screw insertion hole through which a fixing screw is inserted. The screw nut is aligned with the axis of the through hole inside the rectangular parallelepiped and the locking nut is positioned.
A first mounting hardware is fixed to the first structural material, and a second mounting hardware is fixed to the second structural material. The upper part of the drawing bolt inserted into the engaging portion of the second mounting hardware from below is inserted into the through hole from below the rectangular parallelepiped member and screwed into the locking nut, and the drawing bolt is attached to the rectangular parallelepiped member. A pulling nut is screwed to the lower part of the pulling bolt and engaged with the second mounting hardware. Then, the pulling nut is tightened, and the first mounting hardware and the second mounting hardware are fastened by the pulling bolt. .

図３（イ）は、木造軸組み工法住宅において、梁１（第１の構造材）と柱２（第２の構造材）が結合される個所であり、本発明による引き寄せ金物８により緊結されている。
引き寄せ金物８は、梁１の下面に固定した第１の取付け金物９と柱２の側面に固定した第２の取付け金物１０及びこれらを結合した引き寄せボルト１１と引きナット１２を備える。 FIG. 3 (a) is a place where the beam 1 (first structural material) and the pillar 2 (second structural material) are coupled in a wooden framed construction method house, and is tightly coupled by the attracting hardware 8 according to the present invention. ing.
The pulling metal 8 includes a first mounting metal 9 fixed to the lower surface of the beam 1, a second mounting metal 10 fixed to the side surface of the column 2, a pulling bolt 11 and a pulling nut 12 that couple them.

第１の取付け金物９は、図４のように、上部材１３と下部材１４及び止めナット１５を有している。上部材１３と下部材１４は、上部材１３に対して下部材の上辺を突き当てて組み合わせるもので、組み合わせると直方体部材１６となる（図５）。直方体部材１６には上下方向の軸線に沿って貫通孔１７とその周辺に固定用ネジ１８（図６イ）を挿通するためのネジ挿通孔１９が貫通して形成されている。貫通孔１７は直方体部材１６の略中央を貫通している。符合２０は接着シートであり、接着層を形成する。   As shown in FIG. 4, the first mounting hardware 9 includes an upper member 13, a lower member 14, and a lock nut 15. The upper member 13 and the lower member 14 are combined by abutting the upper side of the lower member against the upper member 13, and when combined, become a rectangular parallelepiped member 16 (FIG. 5). The rectangular parallelepiped member 16 is formed with a through hole 17 and a screw insertion hole 19 through which a fixing screw 18 (FIG. 6A) is inserted in the periphery thereof along the vertical axis. The through hole 17 passes through substantially the center of the rectangular parallelepiped member 16. Reference numeral 20 denotes an adhesive sheet, which forms an adhesive layer.

この実施例において、第１の取付け金物９における上部材１３は、前記直方体部材１６の上面壁２１と左端壁２２及び右端壁２３となる部分を一体に有し、下部材１４は前記直方体部材１６の底面壁２４と前壁２５及び後壁２６となる部分を一体に有している。
上面壁２１には、長手方向の両側に２個ずつの突部２７が形成され、これに対応して下部材１４における前後の壁２５，２６の上辺には、凹部２８が形成されている。これらの凹凸構造は上部材１３と下部材１４との位置合せのためと直方体部材１６を変形し難くするためである。なお、この嵌合を多少きつめにすると、一旦嵌合させた上部材１３と下部材１４は簡単に外れてしまうことがなく、扱いやすい。
上部材１３の上面壁２１の内面側には、中央の貫通孔１７の両側に止めナット１５の側面に係合する回り止め爪４２が形成されている（図６イ）。 In this embodiment, the upper member 13 in the first mounting hardware 9 integrally has portions that become the top wall 21, the left end wall 22 and the right end wall 23 of the rectangular parallelepiped member 16, and the lower member 14 is the rectangular parallelepiped member 16. The bottom wall 24, the front wall 25, and the rear wall 26 are integrally formed.
Two protrusions 27 are formed on both sides of the upper surface wall 21 in the longitudinal direction, and correspondingly, recesses 28 are formed on the upper sides of the front and rear walls 25 and 26 of the lower member 14. These uneven structures are for positioning the upper member 13 and the lower member 14 and for making the rectangular parallelepiped member 16 difficult to deform. If this fitting is made somewhat tight, the upper member 13 and the lower member 14 once fitted are not easily detached and are easy to handle.
On the inner surface side of the upper surface wall 21 of the upper member 13, a detent pawl 42 that engages with the side surface of the retaining nut 15 is formed on both sides of the central through-hole 17 (FIG. 6A).

止めナット１５はこの実施例において、戻り止め付きナットであって、雌ネジ孔２９の上側周囲に合成樹脂リング３０が装着されている（図６ロ）。止めナット１５は、上部材１３に設けた上貫通孔３１と下貫通孔３２の間に、これらにより形成される貫通孔１７の雌ネジ孔２９の軸線をあわせて配置され、上部材１３の内面から垂下されている回り止め爪４２に係合して位置決めされる。   In this embodiment, the lock nut 15 is a nut with a detent, and a synthetic resin ring 30 is mounted around the upper side of the female screw hole 29 (FIG. 6B). The retaining nut 15 is disposed between the upper through hole 31 and the lower through hole 32 provided in the upper member 13 so as to match the axis of the female screw hole 29 of the through hole 17 formed by these, and the inner surface of the upper member 13. It is positioned by engaging with the detent pawl 42 that is suspended from.

引き寄せボルト１１は、この実施例において、両端に雄ねじ部３３，３４を有し、上端側雄ねじ部３３は第１取付け金物９内の止めナット１５に螺合し、下端側雄ねじ部３４には引きナット１２が螺合する。
第２の取付け金物１０は、柱２に固定される固定部３５（図３イ）と円筒状に屈曲させた係合部３６を一体に備え、係合部３６には引き寄せボルト１１が、上下方向い貫通することができる。この構造はホールダウン用金物の柱側部材に類似する。なお、図３ロにおいて、符合３７はワッシャであり、引き寄せボルト１１に貫通させ、引きナット１２と組み合わせて用いる。 In this embodiment, the pulling bolt 11 has male threaded portions 33 and 34 at both ends, the upper end side male threaded portion 33 is screwed to the set nut 15 in the first mounting hardware 9, and the lower end side male threaded portion 34 is pulled. The nut 12 is screwed.
The second mounting hardware 10 is integrally provided with a fixing portion 35 (FIG. 3A) fixed to the pillar 2 and an engaging portion 36 bent in a cylindrical shape, and the drawing bolt 11 is vertically connected to the engaging portion 36. Can penetrate in any direction. This structure is similar to the pillar-side member of a hole-down hardware. In FIG. 3B, reference numeral 37 denotes a washer that is passed through the pulling bolt 11 and used in combination with the pulling nut 12.

引き寄せ金物８は、次のように取付けられる（図７イ〜ニ）。
第１の取付け金物９の上部材１３と下部材１４を、上部材１３に下部材１４を突き当てて組み合わせる。その際、内部に止めナット１５を位置決めして組み込んでおく。直方体部材１６の下方から下貫通孔３２に引き寄せボルト１１の上端側雄ねじ部３３を挿し込んで内部の止めナット１５に螺合させる。この螺合は、第１の取付け金物９が落下しない程度に軽く螺合させておく。 The attracting hardware 8 is attached as follows (FIGS. 7A to 7D).
The upper member 13 and the lower member 14 of the first mounting fixture 9 are combined with the lower member 14 abutting against the upper member 13. At that time, the retaining nut 15 is positioned and incorporated therein. The upper end side male screw portion 33 of the pulling bolt 11 is inserted into the lower through-hole 32 from below the rectangular parallelepiped member 16 and screwed into the internal set nut 15. This screwing is done so lightly that the first mounting hardware 9 does not fall.

直方体部材１６上面の接着シート２０の剥離紙を取り去り、柱２に取り付けることになる第２の取付け金物１０との位置関係を見ながら引き寄せボルト１１を略垂直に保持し、補強工事のために内壁を取り除いた間隙から、第１の取付け金物９を差し上げる。そして、第１の取付け金物９を前記の接着シート２０で梁１の下面に接着する。これは、引き寄せボルト１１が略垂直であるかを見極めながら行うだけなので、比較簡単に行える。
接着により仮固定されている第１の取付け金物９から引き寄せボルト１１を一旦、抜き取り、第１の取付け金物９を梁の下面に残す（図７ロ）。 The release sheet of the adhesive sheet 20 on the upper surface of the rectangular parallelepiped member 16 is removed, and the drawing bolt 11 is held substantially vertically while observing the positional relationship with the second mounting hardware 10 to be attached to the pillar 2, and the inner wall is used for reinforcement work. The first mounting hardware 9 is provided from the gap from which the is removed. Then, the first mounting hardware 9 is bonded to the lower surface of the beam 1 with the adhesive sheet 20. Since this is only performed while determining whether the pulling bolt 11 is substantially vertical, the comparison can be easily performed.
The pulling bolt 11 is once extracted from the first mounting hardware 9 temporarily fixed by bonding, and the first mounting hardware 9 is left on the lower surface of the beam (FIG. 7B).

ラグスクリューのような固定用ネジ１８を第１の取付け金物９のネジ挿通孔１９に挿し込み、これをロングビット３８を装着した工具７でねじ込む(図７ハ）。これにより、第１の取付け金物９は梁１の下面に固定される。この作業は、狭い空間に引き寄せボルト１１や第２の取付け金物１０がないので視界が良く、また、工具７の邪魔になるものがなく、さらに、固定用ネジ１８を下方から上方へねじ込むだけで、柱２側への固定作業はないから簡単に行える。また、ロングビット３８を利用すれば、内壁と外壁間の狭い空隙からでも作業個所を直視し易く、しかも、それぞれの固定用ネジ１８は、直方体部材１６の挿通ネジ孔１９によって位置が定まっているから正確に作業を行える（図８）。   A fixing screw 18 such as a lag screw is inserted into the screw insertion hole 19 of the first mounting hardware 9, and this is screwed with the tool 7 equipped with the long bit 38 (FIG. 7C). Thereby, the first mounting hardware 9 is fixed to the lower surface of the beam 1. This work has good visibility because there are no pulling bolts 11 and second mounting hardware 10 in a narrow space, there is nothing to obstruct the tool 7, and further only by screwing the fixing screw 18 upward from below. Since there is no fixing work to the pillar 2 side, it can be easily performed. Further, if the long bit 38 is used, it is easy to look directly at the work site even from a narrow gap between the inner wall and the outer wall, and the position of each fixing screw 18 is determined by the insertion screw hole 19 of the rectangular parallelepiped member 16. The work can be performed accurately from (Fig. 8).

再度、引き寄せボルト１１の先端部を、本固定されている第１の取付け金物９の止めナット１５へ確実ににねじ込む。前記引き寄せボルト１１のねじ込みは充分に行い、引き寄せボルト１１の上端側雄ネジ部３３が上部材１３の上貫通孔３１に到達するようにする（図７ニ）。これにより、上端側雄ねじ部３３は、止めナット１５と完全に螺合する。そして、止めナット１５は戻り止め付きであるから、振動などで引き寄せボルト１１と第１の取付け金物９との螺合状態が緩んでしまうことがない。
ついで引き寄せボルト１１の下端から第２の取付け金物１０をその係合部３６（図３）に引き寄せボルト１１を差し込むようにして組み合わせ、第２の取付け金物１０を柱２の面に接触させて摺り上げながら位置決めする。 Again, the tip of the pulling bolt 11 is securely screwed into the set nut 15 of the first mounting hardware 9 that is permanently fixed. The pulling bolt 11 is sufficiently screwed so that the upper end side male screw portion 33 of the pulling bolt 11 reaches the upper through hole 31 of the upper member 13 (FIG. 7D). As a result, the upper end side male screw portion 33 is completely screwed with the set nut 15. Since the lock nut 15 is provided with a detent, the screwed state between the pulling bolt 11 and the first mounting hardware 9 is not loosened due to vibration or the like.
Next, the second mounting hardware 10 is combined from the lower end of the pulling bolt 11 by inserting the pulling bolt 11 into the engaging portion 36 (FIG. 3), and the second mounting hardware 10 is brought into contact with the surface of the column 2 and slid. Position while raising.

ついで、この第２の取付け金物１０をラグスクリューなどで柱２に固定する。引き寄せボルト１１の下端側雄ネジ部３４にワッシャ３７を通し、さらに引きナット１２を螺合して、引き寄せボルト１１を第２取付け金物１０の係合部３６に係合する。第２の取付け金物１０を柱２へ固定するとき、引き寄せボルト１１の上端が振れることがあるが、引寄せボルト１１の上端は梁１とは結合していないので、多少の振れは許容され、作業を行い易い。そして、引きナット１２を緊締し、第１の取付け金物９と第２の取付け金物１０間を緊結する。引き寄せボルト１１を通じて強い引き寄せ力が第１取付け金物９に作用しても直方体構造であるために、平板に比べて断面二次モーメントが大きく、第１取付け金物９に変形は生じない。   Next, the second mounting hardware 10 is fixed to the column 2 with a lag screw or the like. A washer 37 is passed through the lower end side male screw portion 34 of the pulling bolt 11, and the pulling nut 12 is screwed to engage the pulling bolt 11 with the engaging portion 36 of the second mounting hardware 10. When the second mounting hardware 10 is fixed to the pillar 2, the upper end of the pulling bolt 11 may swing, but the upper end of the pulling bolt 11 is not coupled to the beam 1, so that some swinging is allowed, Easy to work. Then, the pull nut 12 is tightened, and the first mounting hardware 9 and the second mounting hardware 10 are tightened. Even if a strong pulling force acts on the first mounting hardware 9 through the pulling bolt 11, it has a rectangular parallelepiped structure, so that the secondary moment is larger than that of the flat plate, and the first mounting hardware 9 is not deformed.

図９,１０は、第２の実施例であり、前記第１の実施例と同じ部材や個所には同じ符合を用い、説明を省略する。第２の実施例が第１の実施例に対して特徴的なのは、第１の取付け金物９の上部材１３と止めナット１５及び引き寄せボルト１１の上端部の構造である。
上部材１３は平板状であって（図９イ）、左右の端壁を有していない。このため、下部材１４と組み合わせると、両端が開口した直方体部材１６を構成する（図９ロ）。また、止めナット１５は、角形頭部３９とナット部４０とからなり、雌ネジ孔２９が貫通している。 9 and 10 show a second embodiment, and the same reference numerals are used for the same members and portions as those in the first embodiment, and the description thereof is omitted. A characteristic of the second embodiment with respect to the first embodiment is the structure of the upper member 13 of the first mounting fixture 9, the locking nut 15 and the upper end of the pulling bolt 11.
The upper member 13 has a flat plate shape (FIG. 9A) and does not have left and right end walls. For this reason, when combined with the lower member 14, a rectangular parallelepiped member 16 having both ends opened is formed (FIG. 9B). The retaining nut 15 includes a square head 39 and a nut portion 40, and the female screw hole 29 passes therethrough.

この止めナット１５は、その雌ネジ孔２９の軸線を直方体部材１６の貫通孔１７の軸線に合せて直方体部材１６の内部に配置される。このとき、角形頭部３９が下部材１４の前後壁２５,２６に接触して回転止めされ、また、ナット部４０が下部材１４に設けた下貫通孔３２から下方へ突出する。
引き寄せボルト１１は上端側雄ねじ部３３の上端にさらに、木ネジ４１が突出して形成されている（図１０ロ）。木ネジは先が尖り、梁１の下面に押し付けて回転させると木材に食い込む。 The retaining nut 15 is arranged inside the rectangular parallelepiped member 16 with the axis of the female screw hole 29 aligned with the axis of the through hole 17 of the rectangular parallelepiped member 16. At this time, the rectangular head portion 39 comes into contact with the front and rear walls 25 and 26 of the lower member 14 and is prevented from rotating, and the nut portion 40 protrudes downward from the lower through hole 32 provided in the lower member 14.
The pulling bolt 11 is further formed with a wood screw 41 protruding from the upper end of the upper end side male screw portion 33 (FIG. 10B). The wood screw has a sharp point, and when it is pressed against the lower surface of the beam 1 and rotated, it bites into the wood.

他の構成は、第１の実施例の場合と格別に異なるところはない。また、取り付けの手順も略同じである。しかし、第１の取付け金物９を梁１の下面に固定用ネジ１８で本固定したのち、引き寄せボルト１１を第１取り付け金物９に螺合するときは、引き寄せボルト１１の上端部を直方体部材１６の下面から下方へ突出している止めナット１５のナット部４０に螺合させ、引き寄せボルト１１の上端を上部材１３の上貫通孔３１に到達させる。これにより、前記上端側雄ネジ部３３から上方に突出した木ネジ４１は梁１の下面にねじ込まれる。木ネジ４１が梁１にねじ込まれると引き寄せボルト１１の上端は固定され、振れることができないので、第１の取付け金物９へ引き寄せボルト１１の上端を固定した後に第２の取付け金物１０を柱２へ固定するときはある程度正確に位置決めして固定するか第２の取付け金物１０を柱２へ固定してから引き寄せボルト１１の最終的なねじ込みを行う必要がある。   Other configurations are not different from those of the first embodiment. Also, the mounting procedure is substantially the same. However, when the first mounting bracket 9 is fixed to the lower surface of the beam 1 with the fixing screw 18 and the pulling bolt 11 is screwed to the first mounting bracket 9, the upper end portion of the pulling bolt 11 is connected to the rectangular parallelepiped member 16. The upper end of the pulling bolt 11 reaches the upper through hole 31 of the upper member 13 by screwing into the nut portion 40 of the retaining nut 15 protruding downward from the lower surface of the upper member 13. Thereby, the wood screw 41 protruding upward from the upper end side male screw portion 33 is screwed into the lower surface of the beam 1. When the wood screw 41 is screwed into the beam 1, the upper end of the pulling bolt 11 is fixed and cannot swing. Therefore, after the upper end of the pulling bolt 11 is fixed to the first mounting hardware 9, the second mounting hardware 10 is attached to the column 2. When it is fixed to, it is necessary to position and fix it accurately to some extent, or to fix the second mounting hardware 10 to the column 2 and finally to screw in the pulling bolt 11.

ナット部４０を有する止めナット１５と引き寄せボルト１１の下端側雄ねじ部３４との螺合寸法は長く、より強い引寄せ力に対抗することができる。また、木ネジ４１のねじ込みにより、振動などによって引き寄せボルト１１と第１の取付け金物９との螺合が緩んでしまうのを防止することができ、長期間に渡り引き寄せボルト１１の緊締状態を維持することができる。
さらに、第１の取付け金物９の直方体部材１６は、両端が開放された構造であるが、引き寄せ力による変形を防止する上では十分な剛性を発揮する。 The threaded dimension between the retaining nut 15 having the nut portion 40 and the lower end side male screw portion 34 of the pulling bolt 11 is long, and can resist a stronger pulling force. Further, the screwing of the wood screw 41 can prevent the screw bolt 11 and the first mounting hardware 9 from loosening due to vibration or the like, and the tightening state of the pull bolt 11 can be maintained over a long period of time. can do.
Further, the rectangular parallelepiped member 16 of the first mounting hardware 9 has a structure in which both ends are opened, but exhibits sufficient rigidity to prevent deformation due to a pulling force.

以上は実施例である。第１取付け金物９の直方体部材１６は、断面半円形の立体形としても良い。また、実施例では、天井裏などの狭い個所で第１の構造材（梁)と第２の構造材（柱）とが接合する個所での取付けを説明し、この発明がこのような個所での引寄せ補強に適したものであること強調したが、この発明の引き寄せ金物８は、一般に、引寄せボルト１１を一方の構造材に貫通させて引き寄せることが困難な結合個所に利用できる。
第１の取付け金物９における直方体部材１６の上面に設けた接着シートは２０は、設けない場合もある。 The above is an example. The rectangular parallelepiped member 16 of the first mounting hardware 9 may be a solid shape having a semicircular cross section. Further, in the embodiment, the installation at the place where the first structural material (beam) and the second structural material (column) are joined at a narrow place such as the back of the ceiling is explained. Although it has been emphasized that it is suitable for pulling reinforcement, it is generally possible to use the pulling metal 8 of the present invention at a joint where it is difficult to pull the pulling bolt 11 through one structural member.
The adhesive sheet 20 provided on the upper surface of the rectangular parallelepiped member 16 in the first mounting hardware 9 may not be provided.
