Description

本発明は建築構造材の軸組において、第1の構造材の側面に接合金具を介して第2の構造材の木口部を突き合わせ、同接合金具を介して両構造材を接合する際の同接合金具の第1の構造材への取付構造に関するものである。   According to the present invention, in the framework of a building structural material, the end of the second structural material is abutted against the side surface of the first structural material via a joint fitting, and both structural materials are joined via the joint fitting. The present invention relates to a structure for attaching a joint fitting to a first structural member.

軸組工法において構造材としての柱と柱、柱と梁あるいは梁と梁を固定する場合においてしばしば接合金具が使用されている。そのような接合金具の一例として特許文献1の意匠公報を挙げる。この特許文献1の接合金具(意匠に係る物品名:建築用梁固定金具)でも例えばその使用状態を示す参考図1のように例えばボルト状部材としての片引きボルトと座金及びナット(あるいは両引きボルト)によって梁に固定するようにしている。

In the frame construction method, a joining metal fitting is often used when fixing a column and a column, a column and a beam, or a beam and a beam as a structural material. The design gazette of patent document 1 is mentioned as an example of such a joining metal fitting. For example, as shown in FIG. 1 showing the state of use of the joint fitting (article name: architectural beam fixing bracket) of Patent Document 1, as shown in FIG. 1, for example, a single pull bolt and a washer and a nut (or double pull) It is fixed to the beam with bolts.
Similar Design Registration No. 1 of Design Registration No. 899148

このような構成において建築物に例えば風や地震等によって構造材の接合箇所に様々な外力が作用することとなる。
例えば上記梁のような横架材に横方向の力がかかると接合金具を介して座金に大きな引っ張り力がかかる可能性がある。そのため従来では座金の面積を比較的大きくして単位面積あたりの耐荷重を軽減することで座金の変形や座金の木部へのめり込み等の不具合を防止している。しかし、それほど座金の面積を大きくしなくとも座金にかかる荷重を軽減でき、引っ張り応力に対向できるボルト状部材を固定する金具が求められていた。
また、同様に横架材の横方向の力として柱を押圧する力、つまり圧縮力が作用する可能性もある。従来ではその圧縮力は片引きボルトには伝達されていなかったので圧縮力は横架材から柱が受けることとなっていた。しかし、接合金具は木材に比べ段違いに強度が高いためこの圧縮力を接合金具にも分散させたいという要請があった。
更に、横架材の上下方向の動きによって片引きボルトに大きな剪断力が作用する可能性がある。もちろん、片引きボルトでも剪断力に抗しうるだけの耐力を備えているものの、瞬間的な非常に大きな力がかかる場合を想定して剪断力を分散させたいという要請があった。
本発明は上記課題を解決するためのものである。その目的は外力が作用した場合に発生する種々の応力に対してより耐力の大きな接合金具の取付構造を提供することにある。
In such a configuration, various external forces act on the joints of the structural material due to, for example, wind or earthquake on the building.
For example, when a horizontal force is applied to the horizontal member such as the beam, a large pulling force may be applied to the washer through the joint fitting. Therefore, conventionally, the area of the washer is made relatively large to reduce the load resistance per unit area, thereby preventing problems such as deformation of the washer and penetration of the washer into the wood part. However, there has been a demand for a metal fitting for fixing a bolt-shaped member that can reduce the load applied to the washer without increasing the area of the washer so much and can oppose the tensile stress.
Similarly, there is a possibility that a force that presses the column, that is, a compressive force, acts as a lateral force of the horizontal member. In the past, the compressive force was not transmitted to the pulling bolt, so the compressive force was received by the column from the horizontal member. However, since the joint metal has a much higher strength than wood, there has been a demand for dispersing this compressive force in the joint metal.
Furthermore, there is a possibility that a large shearing force acts on the pull-out bolt due to the vertical movement of the horizontal member. Of course, there is a demand to disperse the shear force on the assumption that a very large force is applied instantaneously even though the single pull bolt has a proof strength that can resist the shear force.
The present invention is for solving the above-mentioned problems. The object is to provide a mounting structure for a joint fitting that is more resistant to various stresses generated when an external force is applied.

上記課題を解決するために、請求項1に記載の発明では、第1の構造材の側面に接合金具を介して第2の構造材の木口部を突き合わせ、同接合金具を介して両構造材を接合する際の同接合金具の第1の構造材への取付構造であって、前記第1の構造材には外側方から内側方にかけてボルト部材が挿通され、同ボルト部材は本体の両端寄り外周にそれぞれ螺設された雄ネジ部と、同本体の同雄ネジ部間の外周に螺設された前記第1の構造材に螺合するラグスクリューネジ部と、前記両雄ネジ部に螺合された前記第1の構造材の外側面及び内側面にそれぞれ当接する第1及び第2の座金部材から構成され、前記接合金具は前記第1の構造材の側面に当接されるボルト挿通孔が形成された固定板体と、同固定板体の前面から前方に延出され前記第2の構造材の木口部に形成した挿入溝に挿入される挿入板片とを備え、少なくとも前記接合金具側に配置される第2の座金部材は前記第1の構造材の側面に形成された同第2の座金部材の厚みと同深さの凹部内に収容され前記接合金具の前記固定板体が同第2の座金部材の外側端面と当接するとともに、前記ボルト部材の先端が前記接合金具の前記固定板体に形成した前記ボルト挿通孔から同固定板体の前面側に突出し前記第1の構造材の側面と締結部材とによって同固定板体が挟持されるようにしたことをその要旨とする。
これによってボルト部材はラグスクリューネジ部によって強い固定力で第1の構造材に配設され、接合金具は第1の構造材の側面に固定板体によって面着するとともにボルト部材の本体に螺合された第2の座金部材の端面とも面着することとなる。

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the attachment structure for a joining metal fitting according to the present invention will be described below with reference to the drawings.
Example 1
As shown in FIG. 1, the embedded metal fitting 1 made of an alloy according to the first embodiment includes a long and solid main body 2 having a circular cross section. Male screw portions 3 are screwed on the outer periphery of the main body 2 near both ends. A lag screw thread portion 4 is screwed on the outer periphery between the same male thread portions 3 of the main body 2. A threaded washer 5 shown in FIG. 2 is screwed into the male thread portion 3 of the main body 2 of the embedded metal fitting 1. A screwed washer 5 as a washer member has a disk shape, and a through hole 6 is formed at the center thereof. A female screw portion 7 is screwed on the inner peripheral surface of the through hole 6. The threaded washer 5 is provided with a pair of small through-holes 8 having a circular cross section at positions opposed to each other by 180 degrees with the through-hole 6 interposed therebetween. In the first embodiment, two screw washers 5a and 5b are used.

このような埋め込み金具1を接合金具としてのT字金具10を柱に固定するために使用する際の使用方法について説明する。
図3及び図7に示すように、圧延鋼材よりなるT字金具10は略長方形のベース板11と挿入板片12から構成されている。挿入板片12はベース板11に対して直交するようにその中央から後方に延出されており、T字金具10全体として略T字状の平面形状とされている。ベース板11には上下2箇所にボルト用透孔14が形成されている。挿入板片12にはボルト用透孔14と対応する位置に半円形状のボルトスペース15が形成されている。
また、挿入板片12には、切り欠き16と2つのピン用透孔17が形成されている。切り欠き16及びピン用透孔17はドリフトピン19が係合される箇所となる。
一方、T字金具10が装着される柱18の対向する2面には凹部20,21が前もって形成されている。図5に示すように、一方の凹部20から他方の凹部21の中心を通るように貫通孔23が形成されている。T字金具10が取り付けられる側となる内側の凹部21の深さ(前後幅)はネジ付き座金5bの高さと一致する。外側の凹部20は内側の凹部21よりも深くなっている。本実施例1ではT字金具10のボルト用透孔14が上下2つなので凹部20,21及び貫通孔23も上下二段に形成される。
A method of using such an embedded metal fitting 1 for fixing a T-shaped metal fitting 10 as a joining metal fitting to a column will be described.
As shown in FIGS. 3 and 7, a T-shaped bracket 10 made of rolled steel is composed of a substantially rectangular base plate 11 and an insertion plate piece 12. The insertion plate piece 12 extends rearward from the center so as to be orthogonal to the base plate 11, and the T-shaped fitting 10 as a whole has a substantially T-shaped planar shape. Bolt through holes 14 are formed in the base plate 11 at two locations on the upper and lower sides. A semicircular bolt space 15 is formed in the insertion plate piece 12 at a position corresponding to the bolt through hole 14.
The insertion plate piece 12 is formed with a notch 16 and two pin through holes 17. The notch 16 and the pin through-hole 17 are locations where the drift pin 19 is engaged.
On the other hand, recesses 20 and 21 are formed in advance on two opposing surfaces of the column 18 to which the T-shaped fitting 10 is mounted. As shown in FIG. 5, a through-hole 23 is formed so as to pass from one recess 20 to the center of the other recess 21. The depth (front-rear width) of the concave portion 21 on the inner side on which the T-shaped fitting 10 is attached coincides with the height of the screw washer 5b. The outer recess 20 is deeper than the inner recess 21. In the first embodiment, since the bolt through holes 14 of the T-shaped metal fitting 10 are two in the upper and lower directions, the recesses 20 and 21 and the through hole 23 are also formed in two upper and lower stages.

まず図1(b)のように埋め込み金具1の一方の雄ネジ部3に1つ目のネジ付き座金5aを螺合させる。ネジ付き座金5aは雄ネジ部3とラグスクリューネジ部4の継ぎ目まで軸方向に進出してそれ以上はネジ山がないため進出できずそれ以上にネジ付き座金5を回転させる場合にはその回転力は埋め込み金具1自体をラグスクリューネジ部4が木質材に食い込んで行く方向に回転させることとなる。
埋め込み金具1の柱18への装着は例えば図10に示すようなインパクトレンチ24を使用する。インパクトレンチ24のソケット24aに上記一対の小透孔8に挿入可能な特殊工具25を装着する。
まず図5に示すように、埋め込み金具1の本体2の先端(つまりネジ付き座金5aが装着されていない側)を凹部20側に開口した貫通孔23位置に配置する。そして、この状態でインパクトレンチ24の特殊工具25先端をネジ付き座金5aの小透孔8に挿入し、インパクトレンチ24に荷重をかけながら駆動させる。これによって埋め込み金具1は回転し、貫通孔23を案内孔としてラグスクリューネジ部4の作用によって本体2を貫通孔23周囲の木部に食い込ませながら進出していく。ラグスクリューネジ部4は柱18に対して食い込みながら螺合されていくこととなる。図6に示すように、ネジ付き座金5aの裏面が凹部20底面に当接した状態で埋め込み金具1の柱18への取付は完了する。これを上下2段の凹部20,21及び貫通孔23に対して実行する。
First, as shown in FIG. 1B, the first threaded washer 5a is screwed into one male threaded portion 3 of the embedded metal fitting 1. As shown in FIG. The threaded washer 5a extends in the axial direction up to the joint between the male thread part 3 and the lag screw thread part 4, and since there is no further thread, it cannot be advanced and the threaded washer 5 is rotated when it is further rotated. The force rotates the embedded metal fitting 1 itself in a direction in which the lag screw screw portion 4 bites into the wood material.
For example, an impact wrench 24 as shown in FIG. 10 is used to attach the embedded metal fitting 1 to the column 18. A special tool 25 that can be inserted into the pair of small through holes 8 is attached to the socket 24 a of the impact wrench 24.
First, as shown in FIG. 5, the tip of the main body 2 of the embedded metal fitting 1 (that is, the side where the screwed washer 5a is not mounted) is arranged at the position of the through hole 23 opened to the concave portion 20 side. In this state, the tip of the special tool 25 of the impact wrench 24 is inserted into the small through hole 8 of the screw washer 5a, and the impact wrench 24 is driven while applying a load. As a result, the embedded metal fitting 1 rotates and advances while the main body 2 is biting into the wood portion around the through hole 23 by the action of the lag screw screw portion 4 using the through hole 23 as a guide hole. The lag screw screw portion 4 is screwed into the column 18 while being bitten. As shown in FIG. 6, the mounting of the embedded metal fitting 1 to the column 18 is completed in a state where the back surface of the screw washer 5 a is in contact with the bottom surface of the recess 20. This is performed for the upper and lower concave portions 20 and 21 and the through hole 23.

この状態で埋め込み金具1の本体2の先端は柱18の内側面から突出する。そして、内側の凹部21側から突出した雄ネジ部3に2つ目のネジ付き座金5bを螺合させる。ネジ付き座金5bは凹部21の底面に当接した状態で図6に示すように柱18の外面(つら)と自身の外面がちょうど一致することとなる。この段階で柱18から突出した埋め込み金具1の上下の雄ネジ部3に対してT字金具10のベース板11のボルト用透孔14を挿通させるように配置し、最後にボルトスペース35内に突出する雄ネジ部3に締結部材としてのナット26を螺合させT字金具10を柱18に対して締め付け固定する(図3及び図4の状態)。この時、ネジ付き座金5bの外側端面とベース板11の前面とが当接する。これによってT字金具10からの押圧力がネジ付き座金5bを介して埋め込み金具1の本体2に伝達されることとなる。
このようにしてT字金具10が取り付けられた柱18に対して図3の矢印及び図7に示すように梁27をセットし、側面からドリフトピン19によって固定することで剛接合が完了する。
In this state, the tip of the body 2 of the embedded metal fitting 1 protrudes from the inner surface of the column 18. Then, the second threaded washer 5b is screwed into the male thread portion 3 protruding from the inner recess 21 side. As shown in FIG. 6, the threaded washer 5 b is in contact with the bottom surface of the recess 21, so that the outer surface (icicle) of the column 18 and its own outer surface are exactly aligned. At this stage, the bolt through hole 14 of the base plate 11 of the T-shaped bracket 10 is inserted into the upper and lower male screw portions 3 of the embedded bracket 1 protruding from the column 18, and finally, in the bolt space 35. A nut 26 as a fastening member is screwed into the projecting male screw portion 3 to fasten and fix the T-shaped fitting 10 to the column 18 (state shown in FIGS. 3 and 4). At this time, the outer end surface of the screwed washer 5b and the front surface of the base plate 11 abut. As a result, the pressing force from the T-shaped metal fitting 10 is transmitted to the main body 2 of the embedded metal fitting 1 through the screw washer 5b.
In this way, the beam 27 is set on the column 18 to which the T-shaped fitting 10 is attached as shown in the arrow of FIG. 3 and FIG. 7 and fixed by the drift pin 19 from the side surface, thereby completing the rigid joint.

実施例1のように構成することにより、次のような効果が奏されることとなる。
(1)梁27に対して強い引っ張り力が作用した場合に従来ではT字金具を固定するボルトに生じた引っ張り応力を座金のみで持ちこたえるようになっていた。しかし、本実施例2の埋め込み金具1を使用することによって両引きボルトの引っ張り応力をネジ付き座金5aとラグスクリューネジ部4の両方で持ちこたえるようにしたため、従来に較べてネジ付き座金5aを小さく構成することができる。
(2)柱18に対して梁27方向から柱を押圧する押圧力が作用した場合に、従来ではT字金具を固定するボルトにはその押圧力は伝達されにくく、単に柱の側面で受けるのみであった。ところが、上記のように構成したため梁27方向から柱を押圧する押圧力が作用するとその押圧力はT字金具10からネジ付き座金5bを介して埋め込み金具1に伝達されることとなる。そして、埋め込み金具1はネジ付き座金5bとラグスクリューネジ部4の両方で押圧力に抗することができるため、応力に対して高耐力の埋め込み金具1に力を分散させることができ、構造物の強度向上に貢献する。
(3)柱18に対して梁27が上下方向に移動するような剪断力が作用した場合に、従来ではT字金具を固定するボルトがその剪断力に対する耐力を有することとなっていた。しかし、本実施例1のように本体2の最もT字金具10寄りに本体2にしっかりと螺合されたネジ付き座金5bを配置するようにしたため、剪断力に対して本体2よりも幅広のネジ付き座金5bによって非常に効率的に対抗することが可能となっている。
(4)経年経過することによって構造材が痩せる、つまり当初に比べて収縮してしまう現象が生じる。その場合において従来では座金が柱面から浮いてしまいT字金具10がしっかり引っ張られていない場合がある。その場合に強い引っ張り力が作用すると加速度が加わるため座金部に加わる荷重はより大きくなる可能性がある。本実施例2の埋め込み金具1ではラグスクリューネジ部4が柱18内部に螺合されているため、ネジ付き座金5が柱18から浮きにくく、またネジ付き座金5aがたとえ浮いていてもラグスクリューネジ部4が柱18内部に螺合されているため経年経過した場合であっても引っ張り力によって本体2に生じる引っ張り応力に対抗することが可能である。
By configuring as in the first embodiment, the following effects are achieved.
(1) Conventionally, when a strong tensile force is applied to the beam 27, the tensile stress generated in the bolt for fixing the T-shaped metal fitting can be held only by the washer. However, by using the embedded metal fitting 1 of the second embodiment, the tensile stress of the double pulling bolt can be held by both the threaded washer 5a and the lag screw threaded portion 4, so that the threaded washer 5a is made more than conventional. It can be made small.
(2) When a pressing force is applied to the column 18 from the direction of the beam 27, conventionally, the pressing force is hardly transmitted to the bolt for fixing the T-shaped bracket, and is simply received by the side surface of the column. Met. However, since it is configured as described above, when a pressing force is applied to press the column from the beam 27 direction, the pressing force is transmitted from the T-shaped bracket 10 to the embedded bracket 1 via the screw washer 5b. And since the embedded metal fitting 1 can resist the pressing force by both the threaded washer 5b and the lag screw screw portion 4, the force can be distributed to the embedded metal fitting 1 having a high resistance to stress. Contributes to improved strength.
(3) When a shearing force is applied to the column 18 so that the beam 27 moves in the vertical direction, conventionally, the bolt for fixing the T-shaped metal fitting has a resistance to the shearing force. However, since the threaded washer 5b that is firmly screwed to the main body 2 is disposed closest to the T-shaped fitting 10 of the main body 2 as in the first embodiment, it is wider than the main body 2 with respect to the shearing force. The threaded washer 5b can counteract very efficiently.
(4) With the passage of time, a phenomenon occurs in which the structural material becomes thin, that is, shrinks compared to the original. In that case, conventionally, the washer may float from the column surface, and the T-shaped fitting 10 may not be pulled firmly. In this case, if a strong pulling force is applied, acceleration is applied, so that the load applied to the washer portion may become larger. In the embedded metal fitting 1 of the second embodiment, since the lag screw screw portion 4 is screwed into the column 18, the screw washer 5 is not likely to float from the column 18, and even if the screw washer 5a is floated, the lag screw Since the threaded portion 4 is screwed into the column 18, it is possible to counter the tensile stress generated in the main body 2 due to the tensile force even when aged.
