Description

本発明は、直角で交差する木材同士だけでなく、直角以外の傾斜した角度で交差する木材同士の接合を補強可能な木造建物用補強金物、およびその木造建物用補強金物を用いた木造建物に関するものである。 The present invention relates to a reinforcing hardware for a wooden building capable of reinforcing the joint between timbers intersecting at a right angle but also between timbers intersecting at an inclined angle other than a right angle, and a wooden building using the reinforcing hardware for the wooden building. It is a thing.

直角で交差する木材同士だけでなく、直角以外の傾斜した角度で交差する木材同士の接合を補強可能な木造建物用補強金物として、例えば、第1木軸材と第2木軸材とが所定の傾斜角度を有して結合される軸組構造において、第1木軸材のボルト固定面に固定され、該ボルト固定面と平行な軸線のボルト挿通筒部を有した引き寄せ金物と、軸部材の端に頭部を有し該頭部の反対側に雄ネジ部を有するボルトと雄ネジ部に螺合するナットとを有し、引き寄せ金物のボルト挿通筒部にボルトが貫通し、一端側のナット又は頭部がボルト挿通筒部に当接して抜け止め支持されるボルト部材と、第1木軸材のボルト固定面に連続する第2木軸材の羽根座金固定面に固定され、ボルト部材の他端側の頭部又はナットを支持する羽根座金とを備える木造建物用補強金物が提案されている(例えば、特許文献1参照。)。 As reinforcing hardware for wooden buildings that can reinforce not only the joints of woods that intersect at right angles but also the joints of woods that intersect at slopes other than right angles, for example, the first wood shaft material and the second wood shaft material are predetermined. In a framework structure that is joined with an inclination angle of, a metal fitting that is fixed to the bolt fixing surface of the first wood shaft member and has a bolt insertion tube portion of an axis parallel to the bolt fixing surface, and a shaft member. It has a bolt with a head at the end and a male screw part on the opposite side of the head and a nut to be screwed into the male screw part. The nut or head of the bolt comes into contact with the bolt insertion tube to prevent it from coming off and is supported by the bolt member, and the bolt is fixed to the blade seat metal fixing surface of the second wood shaft material that is continuous with the bolt fixing surface of the first wood shaft material. Reinforcing hardware for wooden buildings including a head on the other end of the member or a bolt seat for supporting a nut has been proposed (see, for example, Patent Document 1).

特許第5922738号公報Japanese Patent No. 5922738

しかし、上述の特許文献1に記載の従来の木造建物用補強金物では、羽根座金は、羽根座金固定面から異なる高さとなって形成される一対の嵩上げ片と、一対の嵩上げ片の嵩上げ方向先端同士を一体に接続し羽根座金固定面に対して斜めとなる連結板部と、連結板部に穿設され、軸部材の外径よりも若干大きな内径とされて、該軸部材が貫通するボルト貫通穴と、連結板部の裏面に形成され、一対の嵩上げ片間の空間部側に膨らむ湾曲面よりなり、ボルト貫通穴を貫通したボルト部材の他端側の頭部又はナットの座面対向面が当接する座面となる湾曲凸面とを一体的に具備する構造であるため、形状が複雑で、製造コストがかかる、という問題がある。 However, in the conventional reinforcing hardware for a wooden building described in Patent Document 1 described above, the blade washer has a pair of raised pieces formed at different heights from the blade washer fixing surface and a pair of raised pieces at the tip in the raising direction. A bolt that is integrally connected to each other and is slanted with respect to the blade washer fixing surface, and a bolt that is bored in the connecting plate and has an inner diameter slightly larger than the outer diameter of the shaft member, through which the shaft member penetrates. It consists of a through hole and a curved surface formed on the back surface of the connecting plate portion and bulging toward the space between the pair of raised pieces. Since the structure is integrally provided with a curved convex surface that serves as a bearing surface with which the surfaces abut, there is a problem that the shape is complicated and the manufacturing cost is high.

特に、この従来の木造建物用補強金物では、平面であるボルト頭部又はナットの座面対向面が、羽根座金の湾曲凸面に当接するため、ボルトの軸部の角度によっては、ボルトの軸部の中心線上からズレたボルト頭部又はナットの座面対向面が羽根座金の湾曲凸面に当接するので、ボルトの軸部による引張力を効率良く羽根座金が固定された木材に伝達できないという問題がある。 In particular, in this conventional reinforcing hardware for wooden buildings, the flat bolt head or the seat surface facing surface of the nut abuts on the curved convex surface of the blade washer, so that the bolt shaft portion depends on the angle of the bolt shaft portion. Since the bolt head or the bearing surface facing surface of the nut displaced from the center line of the bolt abuts on the curved convex surface of the blade washer, there is a problem that the tensile force due to the shaft portion of the bolt cannot be efficiently transmitted to the wood to which the blade washer is fixed. be.

また、この羽根座金は、ボルト部材が首を振って回動する方向に一対の嵩上げ片が設けられている為、ボルト部材の角度によっては連結板部のボルト貫通穴を貫通したボルト部材頭部が一方の嵩上げ片内側面と干渉する場合があり、傾斜して交差する木材同士の接合を補強できないおそれもある。 Further, since this blade washer is provided with a pair of raised pieces in the direction in which the bolt member swings and rotates, the head of the bolt member penetrates the bolt through hole of the connecting plate depending on the angle of the bolt member. May interfere with the inner surface of one of the raised pieces, and may not be able to reinforce the joint between the slanted and intersecting timbers.

さらに、既存の水平用の金物をそのまま利用すると、斜め部分に合わせて木材を大きく座ぼりする必要がある等、木材側の欠損が大きくなったり、金物と木材が極端に近くなる等の不具合が発生する。 Furthermore, if the existing horizontal hardware is used as it is, there will be problems such as the need to sit a large amount of wood in accordance with the diagonal part, large defects on the wood side, and the hardware and wood becoming extremely close to each other. Occur.

そこで、本発明はこのような課題に着目してなされたもので、シンプルな形状で製造コストをかけず、かつ、木材同士の接合角度に依存せずに引張力を効率良く伝達して確実に補強することができる木造建物用補強金物、およびその木造建物用補強金物を用いた木造建物を提供することを目的とする。 Therefore, the present invention has been made by paying attention to such a problem, and has a simple shape, does not incur manufacturing costs, and efficiently transmits tensile force without depending on the joining angle between woods to ensure reliable transmission. It is an object of the present invention to provide a reinforcing hardware for a wooden building that can be reinforced, and a wooden building using the reinforcing hardware for the wooden building.

It has a back plate portion 12a that is fixed to the other wood by penetrating or driving the fixture 2 into the 12a5, and a pair of side plate portions 12b and 12b that are provided upright from both sides of the back plate portion 12a.

一対の側板部12b,12bには、それぞれ、対向するように引寄せ金具13の丸鋼ナット13bの外径R3に応じ、丸鋼ナット13bの19mmの外径R3よりも僅かに大きい20mmの内径R4(図5(b)参照。)を有する丸鋼ナット支持孔12b1,12b1が形成され、その丸鋼ナット支持孔12b1,12b1は、丸鋼ナット13bが挿入され、その後丸鋼ナット13bに軸部材13a先端が螺合して連結することによって、丸鋼ナット13bを回動可能、かつ、脱落させずに支持する。 The pair of side plate portions 12b and 12b have an inner diameter of 20 mm, which is slightly larger than the 19 mm outer diameter R3 of the round steel nut 13b, according to the outer diameter R3 of the round steel nut 13b of the pulling metal fitting 13 so as to face each other. Round steel nut support holes 12b1, 12b1 having R4 (see FIG. 5B) are formed, and the round steel nut support holes 12b1, 12b1 are inserted into the round steel nuts 13b, and then the shaft is inserted into the round steel nuts 13b. By screwing and connecting the tips of the members 13a, the round steel nuts 13b can be rotated and supported without falling off.

また、一対の側板部12b,12bは、それぞれ、図5(b)に示すように、正面視、丸鋼ナット支持孔12b1,12b1の中心12b1aを中心として半径rとする円弧の円弧状輪郭部12b2を有すると共に、その円弧状輪郭部12b2に連続して背板部12aまで斜めに延びる傾斜辺輪郭部12b3を有するように構成されている。 Further, as shown in FIG. 5B, the pair of side plate portions 12b and 12b are arcuate contour portions having an arc shape centered on the center 12b1a of the round steel nut support holes 12b1 and 12b1 in front view, respectively. It has 12b2 and is configured to have an inclined side contour portion 12b3 that extends diagonally to the back plate portion 12a continuously with the arcuate contour portion 12b2.

ここで、円弧状輪郭部12b2の半径rは、第1固定金具11の背板部11aの底面から軸部材支持孔11b1の中心11b1aまでの高さh1(図2(c)参照。)と同じ長さである22mmとし、円弧状輪郭部12b2の中心角θは、例えば、約180°前後の角度とする。 Here, the radius r of the arcuate contour portion 12b2 is the same as the height h1 (see FIG. 2C) from the bottom surface of the back plate portion 11a of the first fixing bracket 11 to the center 11b1a of the shaft member support hole 11b1. The length is 22 mm, and the central angle θ of the arcuate contour portion 12b2 is, for example, an angle of about 180 °.

また、第2固定金具12は、図7に示すような平板状態の背板部12aおよび一対の側板部12b,12bから折曲げ線12c,12cに沿って背板部12aに対し一対の側板部12b,12bを曲げて起立させるが、その際、側板部12b,12bの円弧状輪郭部12b2と背板部12aとの境界部分で折曲げられないよう、側板部12b,12bの円弧状輪郭部12b2,12b2と背板部12aとの境界部分にそれぞれ切欠部12b4,12b4を形成して、側板部12b,12b側にも背板部12aの短辺と直線的に連続する輪郭部分を設ける。 Further, the second fixing bracket 12 has a pair of side plate portions with respect to the back plate portion 12a along the bending lines 12c and 12c from the back plate portion 12a and the pair of side plate portions 12b and 12b in a flat plate state as shown in FIG. 12b, 12b is bent to stand up, but at that time, the arcuate contour portion of the side plate portions 12b, 12b is not bent at the boundary portion between the arcuate contour portion 12b2 of the side plate portions 12b, 12b and the back plate portion 12a. Notches 12b4 and 12b4 are formed at the boundary between 12b2 and 12b2 and the back plate portion 12a, respectively, and contour portions linearly continuous with the short side of the back plate portion 12a are also provided on the side plate portions 12b and 12b.

これにより、折曲げ線12c,12cは、背板部12aの短辺と、その短辺に直線的に連続する側板部12b,12bの切欠部12b4との境界部分を通るので、図7に示すような平板状態の背板部12aおよび一対の側板部12b,12bから折曲げ線12c,12cに沿って背板部12aに対し側板部12b,12bを曲げて起立させても、背板部12aとの境界側板部12b,12bとの境界部分から亀裂等が発生し難くなり、第2固定金物12の強度や耐久性が向上する。 As a result, the bending lines 12c and 12c pass through the boundary portion between the short side of the back plate portion 12a and the notch portion 12b4 of the side plate portions 12b and 12b linearly continuous with the short side, and are shown in FIG. Even if the side plate portions 12b and 12b are bent and stood up with respect to the back plate portion 12a along the bending lines 12c and 12c from the back plate portion 12a and the pair of side plate portions 12b and 12b in such a flat plate state, the back plate portion 12a It becomes difficult for cracks and the like to occur from the boundary portion with the boundary side plate portions 12b and 12b, and the strength and durability of the second fixed metal fitting 12 are improved.

次に、以上のように構成された実施形態の木造建物用補強金物1の使用方法等について説明する。尚、第1固定金具11を固定する一方の木材を第1木材3、第2固定金具12を固定する他方の木材を第2木材4と呼んで説明する。 Next, a method of using the reinforcing hardware 1 for a wooden building of the embodiment configured as described above will be described. One piece of wood for fixing the first fixing bracket 11 will be referred to as a first wood 3, and the other wood for fixing the second fixing bracket 12 will be referred to as a second wood 4.

<木材同士を垂直に接合した場合(補強例1)>
図8および図9は、それぞれ、木材同士を垂直に接合した場合に実施形態の木造建物用補強金物1を用いて補強する手順および補強例1を示す図である。
<When wood is joined vertically (reinforcement example 1)>
8 and 9 are diagrams showing a procedure for reinforcing wood by using the reinforcing metal fitting for a wooden building 1 and a reinforcing example 1 when the timbers are vertically joined to each other, respectively.

まず、図8に示すように、第1固定金具11の背板部11aを、その固定孔11a1~11a3それぞれにネジやビス、釘等の固定具2をインパクトドライバー等によって打込んで柱等の第1木材3に固定する一方、第2固定金具12の背板部12aを、その複数の固定孔12a1~12a5それぞれにビス等の固定具2を同様に打込んで、土台や梁等の第2木材4に固定する。尚、固定具2がボルトの場合、ボルトを第1木材3や第2木材4に貫通させ反対側からナットを螺合して第1固定金具11や第2固定金具12に固定する。また、第1木材3および第2木材4には、例えば、仕口加工を施して接合する。 First, as shown in FIG. 8, the back plate portion 11a of the first fixing bracket 11 is driven into each of the fixing holes 11a1 to 11a3 with a fixing tool 2 such as a screw, a screw, or a nail by an impact driver or the like to drive a pillar or the like. While fixing to the first wood 3, the back plate portion 12a of the second fixing bracket 12 is similarly driven with a fixing tool 2 such as a screw into each of the plurality of fixing holes 12a1 to 12a5 to form a base, a beam, or the like. 2 Fix to wood 4. When the fixture 2 is a bolt, the bolt is passed through the first wood 3 and the second wood 4, and a nut is screwed from the opposite side to fix the bolt to the first fixing bracket 11 and the second fixing bracket 12. Further, the first wood 3 and the second wood 4 are joined, for example, by subjecting them to a joint process.

次に、第2木材4に固定した第2固定金具12における側板部12b,12bの丸鋼ナット支持孔12b1,12b1に引寄せ金具13を構成する丸鋼ナット13bを通す一方、第1木材3に固定した第1固定金具11の円筒状軸受け部11bに引寄せ金具13を構成する軸部材13aを通す。尚、第1固定金具11の円筒状軸受け部11bに軸部材13aを通す際、軸部材13aには予め六角ナット13cが螺合済みでも良いし、六角ナット13cが螺合していなくても良い。 Next, the round steel nuts 13b constituting the pulling metal fitting 13 are passed through the round steel nut support holes 12b1 and 12b1 of the side plate portions 12b and 12b in the second fixing metal fitting 12 fixed to the second wood 4, while the first wood 3 The shaft member 13a constituting the pulling metal fitting 13 is passed through the cylindrical bearing portion 11b of the first fixing metal fitting 11 fixed to the above. When the shaft member 13a is passed through the cylindrical bearing portion 11b of the first fixing bracket 11, the hexagon nut 13c may or may not be screwed into the shaft member 13a in advance. ..

その後、図9に示すように、第2固定金具12の丸鋼ナット支持孔12b1,12b1に通した丸鋼ナット13bの雌ネジ孔13b1に、第1固定金具11の円筒状軸受け部11bに通した軸部材13a先端の雄ネジ部13a1を螺合して軸部材13aと丸鋼ナット13bを連結する。その際、丸鋼ナット13bの雌ネジ孔13b1から軸部材13a先端が僅かに突出しし、第2固定金具12を第2木材4に固定している固定具2の頭部に当接しない程度に螺合する。尚、軸部材13a先端が固定具2の頭部に当接しても良い。 After that, as shown in FIG. 9, the female screw hole 13b1 of the round steel nut 13b passed through the round steel nut support holes 12b1 and 12b1 of the second fixing metal fitting 12 is passed through the cylindrical bearing portion 11b of the first fixing metal fitting 11. The male screw portion 13a1 at the tip of the shaft member 13a is screwed to connect the shaft member 13a and the round steel nut 13b. At that time, the tip of the shaft member 13a slightly protrudes from the female screw hole 13b1 of the round steel nut 13b so as not to come into contact with the head of the fixing tool 2 fixing the second fixing bracket 12 to the second wood 4. Screw. The tip of the shaft member 13a may come into contact with the head of the fixture 2.

そして、最後に丸鋼ナット13bとは反対側に螺合している六角ナット13bを締め付けることにより軸部材13aに所定の引張力を付与して第1固定金具11と第2固定金具12とを引寄せ、第1木材3と第2木材4の接合を補強する。 Finally, by tightening the hexagon nut 13b screwed on the side opposite to the round steel nut 13b, a predetermined tensile force is applied to the shaft member 13a to attach the first fixing bracket 11 and the second fixing bracket 12. It attracts and reinforces the joint between the first wood 3 and the second wood 4.

その際、第2固定金具12は、一対の側板部12b,12bそれぞれの円弧状輪郭部12b2が第1木材3に接触するように第1木材3に近付けて第2木材4に固定すると、第1固定金具11の円筒状軸受け部11bの軸部材支持孔11b1の中心11b1aまでの高さh1が22mmであり、また、第2固定金具12の円弧状輪郭部12b2も丸鋼ナット支持孔12b1,12b1の中心12b1aを中心として高さh1と同じ長さである22mmを半径rとする円弧であるため、軸部材13aは第1木材3とほぼ平行になる。 At that time, the second fixing bracket 12 is fixed to the second wood 4 by bringing the pair of side plate portions 12b and 12b each of the arcuate contour portions 12b2 close to the first wood 3 so as to come into contact with the first wood 3. 1 The height h1 to the center 11b1a of the shaft member support hole 11b1 of the cylindrical bearing portion 11b of the fixing bracket 11 is 22 mm, and the arcuate contour portion 12b2 of the second fixing bracket 12 is also a round steel nut support hole 12b1, Since the arc has a radius r of 22 mm, which is the same length as the height h1 with the center 12b1a of 12b1 as the center, the shaft member 13a is substantially parallel to the first wood 3.

そのため、実施形態の木造建物用補強金物1では、軸部材13aが第1木材3とほぼ平行になることにより、第1固定金具11と第2固定金具12とを引寄せて第1木材3と第2木材4の接合を補強する際、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。 Therefore, in the reinforcing hardware 1 for a wooden building of the embodiment, the shaft member 13a is substantially parallel to the first timber 3, so that the first fixing bracket 11 and the second fixing bracket 12 are attracted to the first timber 3. When reinforcing the joint of the second wood 4, the tensile force acting on the shaft member 13a is efficiently transmitted to the first fixing metal fitting 11 and the second fixing metal fitting 12, and the first wood 3 and the second wood 4 are pulled. It is possible to effectively reinforce the joint between the first timber 3 and the second timber 4.

また、第2固定金具12は、一対の側板部12b,12bそれぞれの円弧状輪郭部12b2が第1木材3に接触するように第1木材3に近付けて第2木材4に固定することにより、第2固定金具12の背板部12aに設けられた固定孔12a1~12a5が第1木材3と第2木材4の接合部である隅部に近付くので、ビス等の固定具2を第1木材3と第2木材4の接合部である隅部に近付けて打込んだり貫通させることが可能となり、この点でも第1木材3と第2木材4の接合を効果的に補強することができる。 Further, the second fixing bracket 12 is fixed to the second wood 4 by approaching the first wood 3 so that the arcuate contour portions 12b2 of each of the pair of side plate portions 12b and 12b come into contact with the first wood 3. Since the fixing holes 12a1 to 12a5 provided in the back plate portion 12a of the second fixing bracket 12 approach the corner portion which is the joint portion between the first wood 3 and the second wood 4, the fixing tool 2 such as a screw is attached to the first wood. It is possible to drive or penetrate the corner portion which is the joint portion between the third wood and the second wood 4, and in this respect as well, the joint between the first wood 3 and the second wood 4 can be effectively reinforced.

特に、第2固定金具12では、第2固定金具12を固定具2で第2木材4に固定した後、丸鋼ナット支持孔12b1,12b1に丸鋼ナット13bを入れ込むので、丸鋼ナット13bの真下にもビス等の固定具2を打込んだり貫通させることが可能となり、この点でも第1木材3と第2木材4の接合を効果的に補強することができる。 In particular, in the second fixing bracket 12, after fixing the second fixing bracket 12 to the second wood 4 with the fixing tool 2, the round steel nuts 13b are inserted into the round steel nut support holes 12b1 and 12b1, so that the round steel nuts 13b It is possible to drive or penetrate the fixing tool 2 such as a screw directly underneath, and in this respect as well, the joint between the first wood 3 and the second wood 4 can be effectively reinforced.

また、第2固定金具12の一対の側板部12b,12bは、図5(b)に示すように、正面視、円弧状輪郭部12b2と、その円弧状輪郭部12b2に連続して直線的に背板部12aに近付いていく傾斜輪郭部12b3を有しており、固定孔12a1,12a2両側の側板部12b,12bの高さよりも固定孔12a3両側の側板部12b,12bの高さの方が低く、さらに固定孔12a3両側の側板部12b,12bの高さよりも固定孔12a4,12a5両側の側板部12b,12bの高さの方が低くなる。 Further, as shown in FIG. 5B, the pair of side plate portions 12b and 12b of the second fixing bracket 12 are continuously linearly connected to the arcuate contour portion 12b2 and the arcuate contour portion 12b2 in front view. It has an inclined contour portion 12b3 that approaches the back plate portion 12a, and the height of the side plate portions 12b, 12b on both sides of the fixing hole 12a3 is higher than the height of the side plate portions 12b, 12b on both sides of the fixing holes 12a1, 12a2. Further, the heights of the side plate portions 12b and 12b on both sides of the fixing holes 12a3 are lower than the heights of the side plate portions 12b and 12b on both sides of the fixing holes 12a3.

そのため、固定孔12a1,12a2よりも固定孔12a3、また固定孔12a3よりも固定孔12a4,12a5の方がインパクトドライバー等の工具の先端を挿入し易くなり、固定具2を第2木材4に対し打込んだり挿入し易くなると共に、工具の可動域が広くなり、側板部12b,12bが邪魔にならなくなるので、作業効率を向上させることができる。 Therefore, the fixing holes 12a3 are easier to insert than the fixing holes 12a1 and 12a2, and the fixing holes 12a4 and 12a5 are easier to insert the tips of tools such as an impact driver than the fixing holes 12a3. The work efficiency can be improved because the movable range of the tool is widened and the side plate portions 12b and 12b do not get in the way as well as being easy to drive and insert.

<When fixing an oblique beam at an angle of 60 ° to the horizontal lumber (reinforcement example 2)>
FIG. 10 is a diagram showing a reinforcement example 2 reinforced by using the reinforcement hardware 1 for a wooden building of the embodiment when the oblique beam is fixed to the horizontal member at an angle of 60 °.

図10に示す補強例2は、第1固定金具11が固定される第1木材3が斜め梁であり、第2固定金具12が固定される水平梁等の第2木材4に対し60°の角度で接合しており、木造建物用補強金物1は、120°の鈍角側に設置している。尚、木材同士の接合角度を除いて、第1固定金具11、第2固定金具12および引寄せ金具13の連結方法は、図8および図9に示す補強例1の場合と同様である。 In the reinforcement example 2 shown in FIG. 10, the first timber 3 to which the first fixing bracket 11 is fixed is an obtuse beam, and the temperature is 60 ° with respect to the second timber 4 such as a horizontal beam to which the second fixing bracket 12 is fixed. It is joined at an angle, and the reinforcing hardware 1 for a wooden building is installed on the obtuse angle side of 120 °. Except for the joining angle between the woods, the method of connecting the first fixing bracket 11, the second fixing bracket 12, and the pulling bracket 13 is the same as that of the reinforcing example 1 shown in FIGS. 8 and 9.

そして、図10に示す補強例2でも、第2固定金具12の側板部12b,12bそれぞれの円弧状輪郭部12b2を第1木材3の側面3aに接触するように第2木材4に固定すると、軸部材13aが60°に傾斜した第1木材3とほぼ平行になるので、第1固定金具11と第2固定金具12とを効率良く引寄せて、第1木材3と第2木材4の接合を効果的に補強することができると共に、第2固定金具12を固定するネジやビス、ボルト、釘等の固定具2を第1木材3と第2木材4の接合部である隅部に近付けて打込んだり貫通させることが可能になるので、この点でも第1木材3と第2木材4の接合を効果的に補強することができる。 Further, also in the reinforcement example 2 shown in FIG. 10, when the arcuate contour portions 12b2 of the side plate portions 12b and 12b of the second fixing bracket 12 are fixed to the second wood 4 so as to be in contact with the side surface 3a of the first wood 3. Since the shaft member 13a is substantially parallel to the first timber 3 inclined at 60 °, the first fixing bracket 11 and the second fixing bracket 12 are efficiently attracted to join the first timber 3 and the second timber 4. Can be effectively reinforced, and fixtures 2 such as screws, screws, bolts, and nails that fix the second fixing bracket 12 are brought closer to the corners that are the joints between the first wood 3 and the second wood 4. Since it is possible to drive or penetrate the wood, the joint between the first wood 3 and the second wood 4 can be effectively reinforced in this respect as well.

<When fixing an oblique beam at an angle of 30 ° to the horizontal lumber (reinforcement example 3)>
FIG. 11 is a diagram showing a reinforcement example 3 in which woods are joined together at an angle of 30 ° and reinforced by using the reinforcing hardware 1 for a wooden building of the embodiment.

図11に示す補強例3は、第1固定金具11が固定される第1木材3が斜め梁であり、第2固定金具12が固定される水平梁等の第2木材4に対し30°の角度で接合しており、木造建物用補強金物1は、150°の鈍角側に設置している。尚、木材同士の接合角度を除いて、第1固定金具11、第2固定金具12および引寄せ金具13の連結方法は、図8および図9に示す場合と同様である。 In the reinforcing example 3 shown in FIG. 11, the first timber 3 to which the first fixing bracket 11 is fixed is an obtuse beam, and the temperature is 30 ° with respect to the second timber 4 such as a horizontal beam to which the second fixing bracket 12 is fixed. It is joined at an angle, and the reinforcing hardware 1 for a wooden building is installed on the obtuse angle side of 150 °. Except for the joining angle between the woods, the method of connecting the first fixing bracket 11, the second fixing bracket 12, and the pulling bracket 13 is the same as that shown in FIGS. 8 and 9.

そして、図11に示す場合でも、第2固定金具12の側板部12b,12bそれぞれの円弧状輪郭部12b2を第1木材3になるべく近付くように第1木材3に近付けて第2木材4に固定することにより、軸部材13aが30°に傾斜した第1木材3と平行になり、第1固定金具11と第2固定金具12とを効率良く引寄せて、第1木材3と第2木材4の接合を効果的に補強することができると共に、第2固定金具12を固定するネジやビス、ボルト、釘等の固定具2を第1木材3と第2木材4の接合部である隅部に近付けて打込んだり貫通させることが可能になるので、この点でも第1木材3と第2木材4の接合を効果的に補強することができる。 Even in the case shown in FIG. 11, the arcuate contour portions 12b2 of the side plate portions 12b and 12b of the second fixing bracket 12 are brought close to the first wood 3 and fixed to the second wood 4 so as to be as close as possible to the first wood 3. By doing so, the shaft member 13a becomes parallel to the first timber 3 inclined at 30 °, and the first fixing bracket 11 and the second fixing bracket 12 are efficiently attracted to the first timber 3 and the second timber 4. It is possible to effectively reinforce the joint between the first wood 3 and the corner portion where the fixing tool 2 such as screws, screws, bolts, nails, etc. for fixing the second fixing metal fitting 12 is the joint portion between the first wood 3 and the second wood 4. Since it is possible to drive or penetrate the wood in close proximity to the wood, the joint between the first wood 3 and the second wood 4 can be effectively reinforced in this respect as well.

<斜め梁の鋭角側に設ける場合(補強例4,5)>
尚、図10に示す補強例2および図11に示す補強例3では、実施形態の木造建物用補強金物1を斜め梁の補強に使用する場合、木造建物用補強金物1を鈍角側に設けるように説明したが、本発明では、これに限らず、図12(a),(b)に示す補強例4,5のように木造建物用補強金物1を斜め梁の鋭角側に設けることもできる。その際、第2固定金具12の側板部12b,12bそれぞれの円弧状輪郭部12b2が斜め梁である第1木材3に接触するように第1木材3に近付けて第2固定金具12を第2木材4に固定することにより、軸部材13aは第1木材3とほぼ平行になるので、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。
<When provided on the acute-angled side of an oblique beam (reinforcement examples 4 and 5)>
In the reinforcement example 2 shown in FIG. 10 and the reinforcement example 3 shown in FIG. 11, when the reinforcing metal fitting 1 for a wooden building of the embodiment is used for reinforcing the diagonal beam, the reinforcing metal fitting 1 for the wooden building is provided on the obtuse angle side. However, in the present invention, the present invention is not limited to this, and the reinforcing hardware 1 for a wooden building can be provided on the acute angle side of the oblique beam as shown in the reinforcing examples 4 and 5 shown in FIGS. 12 (a) and 12 (b). .. At that time, the arcuate contour portions 12b2 of the side plate portions 12b and 12b of the second fixing bracket 12 are brought close to the first timber 3 so as to be in contact with the first timber 3 which is an oblique beam, and the second fixing bracket 12 is seconded. By fixing to the wood 4, the shaft member 13a becomes substantially parallel to the first wood 3, so that the tensile force acting on the shaft member 13a is efficiently transmitted to the first fixing metal fitting 11 and the second fixing metal fitting 12. The first timber 3 and the second timber 4 can be attracted to effectively reinforce the joint between the first timber 3 and the second timber 4.

<木材同士を垂直に接合した場合(補強例6)>
図13(a),(b)は、それぞれ、木材同士を垂直に接合した場合に実施形態の木造建物用補強金物1を用いて補強した補強例6を示す図である。
<When wood is joined vertically (reinforcement example 6)>
13 (a) and 13 (b) are diagrams showing a reinforcement example 6 in which woods are vertically joined to each other and reinforced by using the reinforcing hardware 1 for a wooden building of the embodiment.

この補強例6では、図8および図9に示す補強例1とは異なり、第2固定金具12は、第2木材4の長手方向に対し、第2固定金具12の長手方向が直交するように、図8および図9に示す補強例1の第2固定金具12の固定方向に対し90度回転させて第2木材4に固定している。 In this reinforcement example 6, unlike the reinforcement example 1 shown in FIGS. 8 and 9, the second fixing bracket 12 is such that the longitudinal direction of the second fixing bracket 12 is orthogonal to the longitudinal direction of the second wood 4. , The second fixing bracket 12 of the reinforcing example 1 shown in FIGS. 8 and 9 is rotated 90 degrees with respect to the fixing direction and fixed to the second wood 4.

そして、補強例6の場合、図13(b)に示すように、第2固定金具12は、一対の側板部12b,12bそれぞれの円弧状輪郭部12b2ではなく、丸鋼ナット13bの下側の円形の側面が第1木材3に側面に対向することになるが、第2固定金具12の背板部12aの中心を、第1木材3の側面から22mmの高さにして第2固定金具12を第2木材4に固定することにより、引寄せ金具13の軸部材13aが第1木材3と平行になって第2固定金具12を第2木材4に固定することができる。 Then, in the case of the reinforcing example 6, as shown in FIG. 13B, the second fixing bracket 12 is not the arcuate contour portion 12b2 of each of the pair of side plate portions 12b and 12b, but the lower side of the round steel nut 13b. The circular side surface faces the side surface of the first wood 3, but the center of the back plate portion 12a of the second fixing metal fitting 12 is set to a height of 22 mm from the side surface of the first wood 3, and the second fixing metal fitting 12 is used. By fixing the second wood 4 to the second wood 4, the shaft member 13a of the pulling metal fitting 13 becomes parallel to the first wood 3 and the second fixing metal fitting 12 can be fixed to the second wood 4.

そのため、図13(a),(b)に示す補強例6の場合も、図9~図12に示す補強例1~5の場合と同様に、軸部材13aが第1木材3とほぼ平行になるので、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。 Therefore, in the case of the reinforcing example 6 shown in FIGS. 13 (a) and 13 (b), the shaft member 13a is substantially parallel to the first wood 3 as in the case of the reinforcing examples 1 to 5 shown in FIGS. 9 to 12. Therefore, the tensile force acting on the shaft member 13a is efficiently transmitted to the first fixing metal fitting 11 and the second fixing metal fitting 12, and the first wood 3 and the second wood 4 are attracted to each other, and the first wood 3 and the second wood 3 are attracted to each other. 2 The joint of wood 4 can be effectively reinforced.

その際、図13に示す補強例6の場合と同様に、第2固定金具12の背板部12aの中心を、第1木材3の側面から22mmの高さにして第2固定金具12を第2木材4に固定することにより、引寄せ金具13の軸部材13aが第1木材3とほぼ平行になるので、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。 At that time, as in the case of the reinforcing example 6 shown in FIG. 13, the center of the back plate portion 12a of the second fixing bracket 12 is set to a height of 22 mm from the side surface of the first wood 3, and the second fixing bracket 12 is placed. 2 By fixing to the wood 4, the shaft member 13a of the pulling metal fitting 13 becomes substantially parallel to the first wood 3, so that the tensile force acting on the shaft member 13a is efficiently applied to the first fixing metal fitting 11 and the second fixing metal fitting. It is possible to effectively reinforce the joint between the first timber 3 and the second timber 4 by transmitting to and attracting the first timber 3 and the second timber 4.

そして、図13に示す補強例6や図14に示す補強例7の場合と同様に、第2固定金具12の背板部12aの中心を、第1木材3の側面から22mmの高さにして第2固定金具12を第2木材4に固定することにより、引寄せ金具13の軸部材13aが第1木材3とほぼ平行になるので、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。 Then, as in the case of the reinforcing example 6 shown in FIG. 13 and the reinforcing example 7 shown in FIG. 14, the center of the back plate portion 12a of the second fixing bracket 12 is set to a height of 22 mm from the side surface of the first wood 3. By fixing the second fixing metal fitting 12 to the second wood 4, the shaft member 13a of the pulling metal fitting 13 becomes substantially parallel to the first wood 3, so that the tensile force acting on the shaft member 13a is efficiently first fixed. It is possible to effectively reinforce the joint between the first wood 3 and the second wood 4 by transmitting to the metal fitting 11 and the second fixing metal fitting 12 to attract the first wood 3 and the second wood 4.

<When fixing the climbing beam at an angle of 60 ° to the horizontal lumber (reinforcement example 9)>
FIG. 16 is a diagram showing a reinforcement example 9 reinforced by using the reinforcement hardware 1 for a wooden building of the embodiment when the climbing beam is fixed to the horizontal member at an angle of 60 °. In this case, the first timber 3 is a climbing beam, while the second timber 4 is a purlin or the like.

図16に示す補強例9の場合も、図13~図15に示す補強例6~8の場合と同様に、第2木材4の長手方向に対し第2固定金具12の長手方向が直交するように第2固定金具12を90度回転させて第2木材4に固定する。 In the case of the reinforcing example 9 shown in FIG. 16, as in the case of the reinforcing examples 6 to 8 shown in FIGS. 13 to 15, the longitudinal direction of the second fixing bracket 12 is orthogonal to the longitudinal direction of the second wood 4.

<When fixing the climbing beam at an angle of 15 ° to the horizontal lumber (reinforcement example 10)>
FIG. 17 is a diagram showing a reinforcement example 10 reinforced by using the reinforcement hardware 1 for a wooden building of the embodiment when the climbing beam is fixed to the horizontal member at an angle of 15 °.

図17に示す補強例10の場合も、図16に示す補強例9の場合と同様に、第1木材3が登り梁である一方、第2木材4が棟木等の場合で、第2木材4の長手方向に対し第2固定金具12の長手方向が直交するように第2固定金具12を90度回転させて第2木材4に固定する。 In the case of the reinforcement example 10 shown in FIG. 17, as in the case of the reinforcement example 9 shown in FIG. 16, the first timber 3 is a climbing beam, while the second timber 4 is a purlin or the like, and the second timber 4 is used. The second fixing bracket 12 is rotated 90 degrees so that the longitudinal direction of the second fixing bracket 12 is orthogonal to the longitudinal direction of the second fixing bracket 12, and the second fixing bracket 12 is fixed to the second wood 4.

そして、図13~図16に示す補強例6~9の場合と同様に、第2固定金具12の背板部12aの中心を、第1木材3の側面から22mmの高さにして第2固定金具12を第2木材4に固定することにより、引寄せ金具13の軸部材13aが第1木材3とほぼ平行になるので、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。 Then, as in the case of the reinforcing examples 6 to 9 shown in FIGS. 13 to 16, the center of the back plate portion 12a of the second fixing bracket 12 is set to a height of 22 mm from the side surface of the first wood 3 and the second fixing is performed. By fixing the metal fitting 12 to the second wood 4, the shaft member 13a of the pulling metal fitting 13 becomes substantially parallel to the first wood 3, so that the tensile force acting on the shaft member 13a is efficiently combined with the first fixing metal fitting 11. It can be transmitted to the second fixing bracket 12 to attract the first wood 3 and the second wood 4, and effectively reinforce the joint between the first wood 3 and the second wood 4.

以上説明したように、実施形態の木造建物用補強金物1は、第1固定金具11と、第2固定金具12と、第2固定金具と第1固定金具とを引寄せる引寄せ金具13とを有し、引寄せ金具13は、外周面全体に雄ネジ部13a1が形成された全ねじの軸部材13aと、その軸部材13aの雄ネジ部13a1に螺合する雌ネジ孔13b1が形成された丸鋼ナット13bとを備え、第2固定金具12は、一方の木材である第1木材3に固定される背板部12aと、その背板部12aの両側から起立して設けられた一対の側板部12b,12bとを有し、側板部12b,12bには、それぞれ、丸鋼ナット13bが回動可能に支持する丸鋼ナット支持孔12b1,12b1が形成されている As described above, the reinforcing hardware 1 for a wooden building of the embodiment includes a first fixing metal fitting 11, a second fixing metal fitting 12, and a pulling metal fitting 13 that attracts the second fixing metal fitting and the first fixing metal fitting. The pulling metal fitting 13 has a fully threaded shaft member 13a having a male screw portion 13a1 formed on the entire outer peripheral surface, and a female screw hole 13b1 screwed into the male screw portion 13a1 of the shaft member 13a. A pair of back plate portions 12a fixed to the first wood 3 which is one of the timbers and a pair of back plate portions 12a standing upright from both sides of the back plate portions 12a are provided with round steel nuts 13b. It has side plate portions 12b and 12b, and the side plate portions 12b and 12b are formed with round steel nut support holes 12b1 and 12b1 for rotatably supporting the round steel nut 13b, respectively.

そのため、実施形態の木造建物用補強金物1、および木造建物用補強金物1を用いた木造建物によれば、第1木材3と第2木材4の接合角度が如何なる場合であっても、丸鋼ナット13bの外周面が丸鋼ナット支持孔12b1,12b1の内周面に当接するので、シンプルな形状で製造コストをかけず、かつ、第1木材3と第2木材4の接合角度に依存せずに引張力を効率良く伝達して確実に補強することができる。 Therefore, according to the wooden building reinforcing hardware 1 and the wooden building using the wooden building reinforcing hardware 1, the round steel is used regardless of the joining angle between the first wood 3 and the second wood 4. Since the outer peripheral surface of the nut 13b abuts on the inner peripheral surfaces of the round steel nut support holes 12b1 and 12b1, the simple shape does not incur manufacturing costs and depends on the joining angle between the first wood 3 and the second wood 4. It is possible to efficiently transmit the tensile force without having to reinforce it reliably.

特に、実施形態の木造建物用補強金物1では、第2固定金具12の側板部12b,12bは、それぞれ、12b1aを中心として半径rとする円弧の円弧状輪郭部12b2を有し、その半径rは第1固定金具11の円筒状軸受け部11bの軸部材支持孔11b1の中心11b1aまでの高さh1と同じ長さに構成している。 In particular, in the reinforcing hardware 1 for a wooden building of the embodiment, the side plate portions 12b and 12b of the second fixing bracket 12 each have an arcuate contour portion 12b2 having an arc-shaped contour portion 12b2 centered on 12b1a and having a radius r thereof. Is configured to have the same length as the height h1 up to the center 11b1a of the shaft member support hole 11b1 of the cylindrical bearing portion 11b of the first fixing bracket 11.

そのため、実施形態の木造建物用補強金物1、および木造建物用補強金物1を用いた木造建物によれば、第2固定金具12の側板部12b,12bそれぞれの円弧状輪郭部12b2が第1木材3に接触するように第1木材3に近付けて第2固定金具12を第2木材4に固定することにより、軸部材13aは第1木材3とほぼ平行になるので、軸部材13aに作用する引張力を効率良く第1固定金具11と第2固定金具12とに伝達して第1木材3と第2木材4とを引寄せ、第1木材3と第2木材4の接合を効果的に補強することができる。 Therefore, according to the wooden building reinforcing hardware 1 and the wooden building using the wooden building reinforcing hardware 1, the arcuate contour portions 12b2 of the side plate portions 12b and 12b of the second fixing bracket 12 are the first timber. By fixing the second fixing bracket 12 to the second timber 4 by approaching the first timber 3 so as to come into contact with the third timber 3, the shaft member 13a becomes substantially parallel to the first timber 3 and thus acts on the shaft member 13a. The tensile force is efficiently transmitted to the first fixing metal fitting 11 and the second fixing metal fitting 12, and the first wood 3 and the second wood 4 are attracted to each other, effectively joining the first wood 3 and the second wood 4. Can be reinforced.

また、実施形態の木造建物用補強金物1では、第2固定金具12は、図7に示すような平板状態の背板部12aおよび一対の側板部12b,12bから折曲げ線12c,12cに沿って背板部12aに対し一対の側板部12b,12bを曲げて起立させるが、一対の側板部12b,12bの円弧状輪郭部12b2と背板部12aとの境界部分にそれぞれ切欠部12b4,12b4を設けている。 Further, in the reinforcing metal fitting 1 for a wooden building of the embodiment, the second fixing bracket 12 is formed along the bending lines 12c and 12c from the flat back plate portion 12a and the pair of side plate portions 12b and 12b as shown in FIG. The pair of side plate portions 12b and 12b are bent and erected with respect to the back plate portion 12a. Is provided.

そのため、実施形態の木造建物用補強金物1では、図7に示すような平板状態の背板部12aおよび一対の側板部12b,12bから折曲げ線12c,12cに沿って背板部12aに対し側板部12b,12bを曲げて起立させて第2固定金物12を形成しても、折曲げ線12c,12cは背板部12aの短辺と、その短辺に直線的に連続する側板部12b,12bの切欠部12b4との境界部分を通るので、背板部12aとの境界側板部12b,12bとの境界部分から亀裂等が発生し難くなり、第2固定金物12の強度や耐久性が向上するので、第1木材3と第2木材4を確実に補強することができる。 Therefore, in the reinforcing hardware 1 for a wooden building of the embodiment, from the flat back plate portion 12a and the pair of side plate portions 12b, 12b as shown in FIG. 7, with respect to the back plate portion 12a along the bending lines 12c, 12c. Even if the side plate portions 12b and 12b are bent and raised to form the second fixed metal fitting 12, the bending lines 12c and 12c are the short side of the back plate portion 12a and the side plate portion 12b linearly continuous with the short side. , 12b passes through the boundary portion with the notch portion 12b4, so that cracks and the like are less likely to occur from the boundary portion with the boundary side plate portions 12b and 12b with the back plate portion 12a, and the strength and durability of the second fixed metal fitting 12 are improved. Since it is improved, the first timber 3 and the second timber 4 can be reliably reinforced.
