Description

この発明は、鉄骨系の戸建住宅等の建物に用いられる接合材の中ボルト使用接合構造に関する。   The present invention relates to a joining structure using a medium bolt for a joining material used in a building such as a steel-framed detached house.

一般的な建築において、例えば図６（Ａ）のように柱材２０とブレース材２１との接合部Ａでは、同図（Ｂ）のように溶接接合が行われたり、同図（Ｃ）のように高力ボルト２２を使用した高力ボルト摩擦接合が行われる。しかし、溶接接合の場合、現場溶接とする場合でなければ、現場での調整が難しく施工性に難点がある。一方、高力ボルト摩擦接合の場合、高力ボルトが中ボルトに比べて高価であるためコストアップの要因になる。また、高力ボルトを使用する場合、防錆上の理由から溶融亜鉛メッキボルトとする場合が多いが、この場合、有資格者による施工が必要になる。そのため、住宅等の比較的小規模な建物では、基本として有資格者の要らない中ボルトを用いたボルト接合を採用することが多い。   In general construction, for example, at the joint A between the column member 20 and the brace member 21 as shown in FIG. 6 (A), welding is performed as shown in FIG. 6 (B), or as shown in FIG. Thus, high-strength bolt friction joining using the high-strength bolt 22 is performed. However, in the case of welding joining, unless on-site welding is used, adjustment at the site is difficult and the workability is difficult. On the other hand, in the case of high-strength bolt friction joining, the high-strength bolt is more expensive than the medium bolt, which increases the cost. Moreover, when using a high-strength bolt, it is often a hot-dip galvanized bolt for reasons of rust prevention. In this case, construction by a qualified person is required. For this reason, in relatively small buildings such as houses, bolt joining using a medium bolt that does not require qualified personnel is often employed as a basic rule.

中ボルトをせん断方向に用いた接合では、接合部での滑りにより剛性が低下し、繰り返し時の荷重変位関係において若干のスリップ現象が現れる。例えば、ボルトとボルト挿通孔の内面間のクリアランスでスリップ現象が生じる。また、ボルト引張接合では、相当のプレテンションを加えなければ繰り返し荷重によりボルトが緩むことが懸念される。特に、制震性能を求める場合、履歴に滑りが出ると支障がある。   In the joint using the middle bolt in the shear direction, the rigidity decreases due to slippage at the joint, and a slight slip phenomenon appears in the load displacement relationship at the time of repetition. For example, the slip phenomenon occurs due to the clearance between the bolt and the inner surface of the bolt insertion hole. Further, in bolt tension joining, there is a concern that the bolt will loosen due to repeated loads unless a considerable pretension is applied. In particular, when the damping performance is required, there is a problem if the history slips.

この発明の目的は、中ボルトを用いて、滑りによる剛性低下や、スリップ挙動を生じることなく、確実にかつ容易にボルト接合でき、コスト低減が可能な接合材の中ボルト使用接合構造を提供することである。   SUMMARY OF THE INVENTION An object of the present invention is to provide a joining structure using a medium bolt using a medium bolt, which can be securely and easily bolted without lowering rigidity due to slipping or causing slip behavior, and can reduce costs. That is.

この発明の接合材の中ボルト使用接合構造は、互いに接合面で面接触する２つの接合材が、両接合材の前記接合面を押し付け合うように中ボルトで接合される接合材の中ボルト使用接合構造において、前記両接合材の前記接合面に、互いに対向する溝形の凹部が設けられ、これら凹部間に、両凹部に渡って嵌合する形状のピン状のシアコッターが介在し、前記シアコッターは、前記両凹部を合わせた断面形状よりも大きく、前記中ボルトによる締め付けによって前記凹部に対して締まり嵌めとなることを特徴とする。なお、この明細書において、中ボルトは、現在のＪＩＳ規格等で「中ボルト」として分類された仕上げ程度や強度を持つボルトである。 Bolt used junction structure in the bonding material of the present invention, two bonding material in surface contact with the bonding surfaces to each other, the bolts used in the bonding material that will be joined at the middle barrel so mutually pressing said joint surfaces of the joining material in the junction structure, the said bonding surfaces of the bonding material, provided with a groove-shaped recess facing each other, between these recesses, pin-shaped Shiakotta configured to fit over both the recess is interposed, said Shiakotta Is larger than the combined cross-sectional shape of both the recesses, and is an interference fit to the recesses by tightening with the middle bolt . In this specification, the medium bolt is a bolt having a finishing degree and strength classified as “medium bolt” in the current JIS standard.

この構成によると、中ボルトはせん断方向に用いられるが、両接合材の接合面に溝形の凹部を設け、これら両凹部間に、両凹部に渡って嵌合する形状のピン状のシアコッターを介在させて、両接合材をそれらの接合面を押し付け合うように中ボルトで接合しているので、せん断力が繰り返し加わっても、凹部とシアコッターとの嵌合により、滑りによる剛性低下や、スリップ挙動を生じることがない。例えば、中ボルトとボルト挿通孔の内面との間のクリアランスで滑りを生じることが防止される。シアコッターにはピン状のものを用いるが、中ボルトによる接合面に滑り止め手段として介在させるシアコッターであるため、必要な滑り止め機能が確保でき、かつ楔状等のシアコッターに比べて、形状が簡素で部品コストが易くできる。また、溶接による接合のように現場での調整に困難を伴うことがなく、高力ボルトを用いる場合のように有資格者を必要とすることもないので、施工を容易に行うことができる。さらに、高力ボルトに比べて安価な中ボルトを使用できるので、コスト低減も可能となる。その結果、滑りによる剛性低下や、スリップ挙動を生じることなく、容易にボルト接合でき、コスト低減も可能となる。これにより、戸建住宅程度の小規模の建物において、必要性能とコストがバランスした接合構造となる。
また、両凹部を合わせた断面形状よりも、シアコッターの断面形状が大きいため、中ボルトによる両接合材の締め付けによって、シアコッターが凹部に対して締まり嵌めとなるので、ボルト接合部での滑りによる剛性低下や、スリップ挙動をより確実に防止できる。 According to this configuration, the medium bolt is used in the shearing direction, but a groove-shaped concave portion is provided on the joint surface of both the joining materials, and a pin-shaped shear coater having a shape that fits over both concave portions is provided between the two concave portions. Since both joints are joined with intermediate bolts so that their joint surfaces are pressed against each other, even if shearing force is repeatedly applied, the fitting between the recess and the sheer cotter will cause a reduction in rigidity due to slipping or slipping. There is no behavior. For example, it is possible to prevent slippage due to the clearance between the middle bolt and the inner surface of the bolt insertion hole. A pin is used for the shear cotter, but it is a shear cotter that is interposed as an anti-slip means on the joint surface with the middle bolt, so the necessary anti-slip function can be secured, and the shape is simpler than that of a wedge-shaped shear cotter. Parts cost can be made easy. In addition, there is no difficulty in on-site adjustment as in the case of joining by welding, and since there is no need for qualified personnel as in the case of using high-strength bolts, construction can be performed easily. Furthermore, since a medium bolt that is less expensive than a high-strength bolt can be used, the cost can be reduced. As a result, it is possible to easily join the bolts without lowering the rigidity due to the slip or causing the slip behavior, and to reduce the cost. Thereby, in a small-scale building of a detached house level, it becomes a joint structure in which necessary performance and cost are balanced.
In addition, since the cross-sectional shape of the shear cotter is larger than the cross-sectional shape of the two concave portions, the shear cotter is tightly fitted to the concave portion by tightening both joint materials with a medium bolt, so the rigidity due to slipping at the bolt joint portion Lowering and slipping behavior can be prevented more reliably.

この発明において、前記各凹部が断面半円形の溝形であり、前記シアコッターが円柱形状であっても良い。シアコッターが円柱形状であると、丸鋼の切断片等をシアコッターとして用いることができ、より一層部品コストが低減できる。   In this invention, each said recessed part may be a groove shape with a semicircular cross section, and the said shear cotter may be a column shape. When the shear cotter has a cylindrical shape, a cut piece of round steel or the like can be used as the shear cotter, and the component cost can be further reduced.

この発明において、前記両接合材のうちの一方が制震ダンパーであり、前記両接合材のうちの他方が前記制震ダンパーを支持する支持部材であっても良い。
この発明の中ボルト使用接合構造は、繰り返し荷重を受けても上記のようにスリップ挙動が生じず、滑りによる剛性低下が生じないため、制震ダンパーとその支持部材との接合に用いた場合、制震ダンパーが持つ本来の制震性能を十分に発揮させることができる。 In the present invention, one of the joint materials may be a vibration damping damper, and the other of the joint materials may be a support member that supports the vibration control damper.
The joint structure using the intermediate bolt according to the present invention does not cause the slip behavior as described above even when subjected to repeated loads, and does not cause a decrease in rigidity due to the slip, so when used for joining the damping damper and its support member, The original damping performance of the damping damper can be fully demonstrated.

この発明において、前記２つの接合材が、建築物を構成する部材に設けられた板材であっても良い。建築物を構成する部材とは、例えば柱材、梁材、ブレース材等である。接合材が板材であると、前記シアコッターが嵌合する凹部を加工するにつき、長尺の柱材やブレース材の端面に直接に前記凹部を加工する場合に比べて、加工が簡単に行える。   In the present invention, the two bonding materials may be plate members provided on members constituting the building. The members constituting the building are, for example, pillar materials, beam materials, brace materials, and the like. When the bonding material is a plate material, the recess can be easily processed as compared with the case of processing the recess directly on the end face of the long columnar material or the brace material when the recess into which the sheacotter is fitted is processed.

この発明の接合材の中ボルト使用接合構造は、互いに接合面で面接触する２つの接合材が、両接合材の前記接合面を押し付け合うように中ボルトで接合される接合材の中ボルト使用接合構造において、前記両接合材の前記接合面に、互いに対向する溝形の凹部が設けられ、これら凹部間に、両凹部に渡って嵌合する形状のピン状のシアコッターが介在するため、中ボルトを用いながら、滑りによる剛性低下や、スリップ挙動を生じることがない。また、中ボルトを用いるため、容易にボルト接合でき、コスト低減が可能となる。
また、両凹部を合わせた断面形状よりも、シアコッターの断面形状が大きいため、中ボルトによる両接合材の締め付けによって、シアコッターが凹部に対して締まり嵌めとなるので、ボルト接合部での滑りによる剛性低下や、スリップ挙動をより確実に防止できる。 Bolt used junction structure in the bonding material of the present invention, two bonding material in surface contact with the bonding surfaces to each other, the bolts used in the bonding material that will be joined at the middle barrel so mutually pressing said joint surfaces of the joining material in the junction structure, the said bonding surfaces of the bonding material, provided with a groove-shaped recess facing each other, between these recesses, the pin-like Shiakotta configured to fit over both the recess is interposed, medium While using bolts, there is no reduction in rigidity due to slipping or slipping behavior. Moreover, since the middle bolt is used, the bolt can be easily joined and the cost can be reduced.
In addition, since the cross-sectional shape of the shear cotter is larger than the cross-sectional shape of the two concave portions, the shear cotter is tightly fitted to the concave portion by tightening both joint materials with a medium bolt, so the rigidity due to slipping at the bolt joint portion Lowering and slipping behavior can be prevented more reliably.

この発明の一実施形態を図１ないし図３と共に説明する。この接合材の中ボルト使用接合構造１は、図１（Ａ）に示すように互いに接合面２ａで面接触する２つの接合材２Ａ，２Ｂを、両接合材２Ａ，２Ｂの接合面２ａを互いに押し付け合うように中ボルト３で接合し、シアコッター７を介在させるものである。２つの接合材２Ａ，２Ｂは共に鋼板などの板材からなる。ここでは、一方の接合材２Ａが角形鋼管または形鋼などの鋼材からなる柱１１の側面に、垂直姿勢で溶接により一体に取付けられている。他方の接合材２Ｂは、並設される２本の前記柱１１間に横架される形鋼等の鋼材からなる梁１２の端部に、端板等として、同じく垂直姿勢で溶接により一体に取付けられている。   An embodiment of the present invention will be described with reference to FIGS. As shown in FIG. 1 (A), the joining structure 1 using the intermediate bolt of the joining material is composed of the two joining materials 2A and 2B that are in surface contact with each other on the joining surface 2a, and the joining surfaces 2a of both joining materials 2A and 2B. It joins with the middle volt | bolt 3 so that it may press, and the sheer cotter 7 is interposed. The two bonding materials 2A and 2B are both made of a plate material such as a steel plate. Here, one joining material 2A is integrally attached to the side surface of the column 11 made of a steel material such as a square steel pipe or a shaped steel by welding in a vertical posture. The other joining material 2B is integrally formed by welding in the same vertical posture as an end plate or the like on the end of the beam 12 made of a steel material such as a section steel that is horizontally mounted between the two columns 11 arranged side by side. Installed.

両接合材２Ａ，２Ｂのうち、一方の接合材２Ｂには前記中ボルト３を挿通させる複数のボルト挿通孔４が上下に分けて設けられ、他方の接合材２Ａには、一方の接合材２Ｂと互いに接合した状態で前記ボルト挿通孔４に整合する位置に、複数のねじ孔５が上下に分けて設けられている。ボルト挿通孔４およびねじ孔５の水平方向の並び個数は、１個であっても、２個またはそれ以上であっても良い。両接合材２Ａ，２Ｂの各接合面２ａには、互いに対向する溝形の凹部６がそれぞれ２つ水平方向に延びて設けられている。ここでは、これらの凹部６が断面半円形とされている。   Among the two bonding materials 2A and 2B, one bonding material 2B is provided with a plurality of bolt insertion holes 4 through which the intermediate bolt 3 is inserted, and the other bonding material 2A has one bonding material 2B. A plurality of screw holes 5 are provided separately at the top and bottom at positions aligned with the bolt insertion holes 4 while being joined to each other. The number of the bolt insertion holes 4 and the screw holes 5 arranged in the horizontal direction may be one, or two or more. Two groove-shaped recesses 6 facing each other are provided in each bonding surface 2a of both the bonding materials 2A and 2B so as to extend in the horizontal direction. Here, these recesses 6 are semicircular in cross section.

両接合材２Ａ，２Ｂの凹部６，６間には、それぞれ対応する両凹部６に渡って嵌合する形状の２本のピン状のシアコッター７が介在させられる。ここでは、凹部６の断面形状に合わせて、シアコッター７は円柱形状とされている。シアコッター７は例えば丸鋼からなる。両凹部６間にシアコッター７を介在させて、一方の接合材２Ｂのボルト挿通孔４に挿通させた中ボルト３を他方の接合材２Ａのねじ孔５に螺合させることで、図１（Ｂ）のように両接合材２Ａ，２Ｂが中ボルト３でボルト接合される。ここでは、前記シアコッター７は、前記両凹部６を合わせた断面形状よりも大きくされている。これにより、中ボルト３による締め付けによって、両凹部６に対してシアコッター７が締まり嵌めとなる。   Between the concave portions 6 and 6 of both the bonding materials 2 </ b> A and 2 </ b> B, two pin-shaped sheacotters 7 having a shape that fits over the corresponding concave portions 6 are interposed. Here, the shear cotter 7 has a cylindrical shape in accordance with the cross-sectional shape of the recess 6. The shear cotter 7 is made of, for example, round steel. By inserting a sheer cotter 7 between the two recesses 6 and screwing the middle bolt 3 inserted into the bolt insertion hole 4 of one bonding material 2B into the screw hole 5 of the other bonding material 2A, FIG. The two joining materials 2A and 2B are bolted by the medium bolt 3 as shown in FIG. Here, the shear cotter 7 is made larger than the cross-sectional shape of the concave portions 6 combined. As a result, the shear cotter 7 is tightly fitted to the two recesses 6 by tightening with the middle bolt 3.

図２には、シアコッター７の断面形状を、前記両凹部６を合わせた断面形状よりも大きくするための加工例を示している。シアコッター７の断面がφ１０ｍｍの円形であるとき、凹部６が未加工の前記両接合材２Ａ，２Ｂで厚み０．５ｍｍのプレート８を挟み付けた状態で、これら両接合材２Ａ，２Ｂの側部から両接合材２Ａ，２Ｂに跨がってφ１０ｍｍの孔９を接合面２ａと平行に切削する。この加工後にプレート８を取り除くと、両接合材２Ａ，２Ｂの接合面２ａに加工された凹部６は、これら両凹部６を合わせた断面形状がシアコッター７の断面形状よりも小さくなる。つまり、加工された両凹部６を合わせた断面形状よりも、シアコッター７の断面形状を大きくできる。   FIG. 2 shows an example of processing for making the cross-sectional shape of the shear cotter 7 larger than the cross-sectional shape of the both concave portions 6 combined. When the cross section of the shear cotter 7 is a circle having a diameter of 10 mm, the side portions of the two bonding materials 2A and 2B are formed in a state in which the concave portion 6 is sandwiched between the unprocessed both bonding materials 2A and 2B and the plate 8 having a thickness of 0.5 mm. Then, a hole 9 having a diameter of 10 mm is cut in parallel with the joining surface 2a across the joining materials 2A and 2B. When the plate 8 is removed after this processing, the cross-sectional shape of the concave portions 6 processed on the bonding surfaces 2a of both the bonding materials 2A and 2B becomes smaller than the cross-sectional shape of the shear coater 7 together. That is, the cross-sectional shape of the shear cotter 7 can be made larger than the cross-sectional shape obtained by combining both processed recesses 6.

この構成の接合材の中ボルト使用接合構造１によると、両接合材２Ａ，２Ｂの接合面２ａに溝形の凹部６を設け、これら両凹部６間に、両凹部６に渡って嵌合する形状のピン状のシアコッター７を介在させて、両接合材２Ａ，２Ｂをそれらの接合面２ａを押し付け合うように中ボルト３で接合したので、図１（Ｂ）に矢印Ｖで示すようなせん断力が繰り返し加わっても、凹部６とシアコッター７との嵌合により、滑りによる剛性低下や、スリップ挙動を生じることがない。中ボルト３とボルト挿通孔４との間には、若干のクリアランスが設けられるが、このクリアランス内で滑りを乗じることがない。シアコッター７にはピン状のものを用いるが、中ボルト１３による接合面に２ａに滑り止め手段として介在させるシアコッターであるため、必要な滑り止め機能が確保でき、かつ楔状等のシアコッターに比べて、形状が簡素で部品コストが易くできる。   According to the joining structure 1 using the intermediate bolt of the joining material having this configuration, the groove-shaped recess 6 is provided on the joining surface 2a of both the joining materials 2A and 2B, and the both recesses 6 are fitted over the both recesses 6. Since the pin-shaped sheacotter 7 is interposed and the two joining materials 2A and 2B are joined with the intermediate bolt 3 so as to press the joining surfaces 2a against each other, the shear as shown by the arrow V in FIG. Even if a force is repeatedly applied, the fitting between the recess 6 and the shear cotter 7 does not cause a decrease in rigidity due to slip or a slip behavior. A slight clearance is provided between the middle bolt 3 and the bolt insertion hole 4, but no slip is applied within this clearance. Although a pin-shaped thing is used for the sheer cotter 7, since it is a sheer cotter interposed as a non-slip means on the joint surface by the intermediate bolt 13, a necessary anti-slip function can be secured, and compared with a shear-like cotter such as a wedge, The shape is simple and the parts cost can be made easy.

また、溶接による接合のように現場での調整に困難を伴うことがなく、高力ボルトを用いる場合のように有資格者を必要とすることもないので、施工を容易に行うことができる。さらに、高力ボルトに比べて安価な中ボルトを使用できるので、コストを低減することもできる。   In addition, there is no difficulty in on-site adjustment as in the case of joining by welding, and since there is no need for qualified personnel as in the case of using high-strength bolts, construction can be performed easily. Furthermore, since a medium bolt that is less expensive than a high-strength bolt can be used, the cost can be reduced.

図３（Ａ）は、中ボルトを用いた従来の構造の場合の耐力試験結果のグラフを示し、図３（Ｂ）はこの実施形態のボルト接合構造１の場合の耐力試験結果をグラフで示している。従来の接合構造のでは、丸印で囲んだ範囲内でスリップ挙動が生じているが、実施形態の中ボルト使用接合構造１では、同図（Ａ）のようなスリップ挙動が生じていない。これらのグラフの比較からも、この実施形態の中ボルト使用接合構造１で滑りが解消されていることが分かる。   FIG. 3A shows a graph of the proof stress test result in the case of the conventional structure using the middle bolt, and FIG. 3B shows the proof stress test result in the case of the bolt joint structure 1 of this embodiment. ing. In the conventional joining structure, the slip behavior occurs within the range surrounded by the circle, but the slip behavior as shown in FIG. From the comparison of these graphs, it can be seen that slippage is eliminated in the middle bolt using joint structure 1 of this embodiment.

また、この実施形態では、前記両接合材２Ａ，２Ｂの両凹部６を合わせた断面形状よりも、シアコッター７の断面形状を大きくしているので、中ボルト３による両接合材２Ａ，２Ｂの締め付けによって、シアコッター７が凹部６に対して締まり嵌めとなり、ボルト接合部での緩みや滑りの発生をより確実に防止できる。   Moreover, in this embodiment, since the cross-sectional shape of the shear cotter 7 is made larger than the cross-sectional shape of both the concave portions 6 of the two joining materials 2A and 2B, the fastening of the two joining materials 2A and 2B by the intermediate bolt 3 is performed. Thus, the shear cotter 7 is an interference fit with respect to the recess 6, and the occurrence of loosening and slippage at the bolt joint can be more reliably prevented.

図４は、上記実施形態の接合材の中ボルト使用接合構造１を、間柱型耐力壁１３への制震ダンパー１０の組み込みに使用した例を正面図で示している。この間柱型耐力壁１３では、その間柱１４を上側柱部１４ａと下側柱部１４ｂに分断して、制震ダンパー１０の一方の支持部材となる上側端部１４ａの下端と制震ダンパー１０の上端とが前記中ボルト使用接合構造１によって接合されると共に、制震ダンパー１０の他方の支持部材となる下側端部１４ｂの上端と制震ダンパー１０の下端とが同じく前記中ボルト使用接合構造１によって接合されている。   FIG. 4 is a front view showing an example in which the middle bolt using joint structure 1 of the above-described embodiment is used for assembling the damping damper 10 into the stud-type bearing wall 13. In the stud-type bearing wall 13, the stud 14 is divided into an upper pillar part 14 a and a lower pillar part 14 b, and the lower end of the upper end part 14 a serving as one support member of the damping damper 10 and the damping damper 10. The upper end is joined by the middle bolt-use joining structure 1, and the upper end of the lower end portion 14 b that is the other support member of the damping damper 10 and the lower end of the damping damper 10 are the same. 1 is joined.

このように、制震ダンパー１０をその支持部材に接合するのに、繰り返し荷重を受けても滑りによる剛性低下やスリップ挙動を生じない上記実施形態の中ボルト使用接合構造１を用いた場合、制震ダンパー１０が持つ本来の制震性能を十分に発揮させることができる。その他の制震デバイスを組み込むときにも、上記実施形態の中ボルト使用接合構造１を用いれば同様の効果を上げることができる。   As described above, when the vibration damping damper 10 is joined to the support member, the use of the middle bolt joint structure 1 according to the above embodiment that does not cause a reduction in rigidity due to slip or slip behavior even when subjected to repeated loads is used. The original seismic performance of the seismic damper 10 can be fully exhibited. Even when other seismic control devices are incorporated, the same effect can be obtained by using the middle bolt use joint structure 1 of the above embodiment.

図５は、上記実施形態の接合材の中ボルト使用接合構造１を、間柱型耐力壁１３への制震ダンパー１０の組み込みに使用した他の例を正面図で示している。この間柱型耐力壁１３では、柱１１とブレース１５の下端との接合部に前記制震ダンパー１０を介在させ、この制震ダンパー１０と柱１１との接合に前記中ボルト使用接合構造１を用いている。
この構成の場合も、繰り返し荷重を受けても滑りによる剛性低下やスリップ挙動を生じない上記実施形態の中ボルト使用接合構造１を用いることで、制震ダンパー１０が持つ本来の制震性能を十分に発揮させることができる。 FIG. 5 is a front view showing another example in which the middle bolt use joint structure 1 of the above-described embodiment is used for assembling the vibration damper 10 into the stud-type bearing wall 13. In this inter-column type bearing wall 13, the damping damper 10 is interposed at the joint between the pillar 11 and the lower end of the brace 15, and the joining structure 1 using medium bolts is used for joining the damping damper 10 and the pillar 11. ing.
In the case of this configuration, the original damping performance of the damping damper 10 can be sufficiently obtained by using the intermediate bolt joint structure 1 according to the above-described embodiment that does not cause a reduction in rigidity or slipping behavior due to slippage even when subjected to repeated loads. Can be demonstrated.

なお、参考例であるが、上記実施形態における一方の接合材２Ａの凹部６を、開口側が長辺となる断面台形状に形成すると共に、前記シアコッター７に代わって前記凹部６に嵌合する断面台形状の凸部を他方の接合材２Ｂの接合面２ａに一体に形成して、中ボルト３により両接合材２Ａ，２Ｂを締め付けるとき、前記凸部が前記凹部６に締まり嵌めとなるように構成しても良い。これにより、ボルト接合部での緩みや滑りの発生を防止できる。この場合、締め付け前の状態で、前記凸部の天面と前記凹部６の底面との間に若干の隙間が生じるようにしておけば、中ボルト３による両接合材２Ａ，２Ｂの締め付けにおいて、前記凹部６に対して前記凸部をより確実に締まり嵌めの状態にすることができる。   In addition, although it is a reference example, while forming the recessed part 6 of one joining material 2A in the said embodiment in the cross-sectional trapezoid shape whose opening side becomes a long side, it replaces with the said shear cotter 7, and is a cross section fitted to the said recessed part 6 When the trapezoidal convex part is integrally formed on the joining surface 2a of the other joining material 2B and both joining materials 2A and 2B are tightened by the intermediate bolt 3, the projecting part becomes an interference fit with the recessed part 6. It may be configured. As a result, it is possible to prevent looseness and slippage at the bolt joint. In this case, if a slight gap is generated between the top surface of the convex portion and the bottom surface of the concave portion 6 in a state before tightening, in tightening both the joining materials 2A and 2B with the intermediate bolt 3, The convex portion can be more securely tightened with respect to the concave portion 6.

また、他の参考例を示すと、前記両接合材２Ａ，２Ｂに凹部６を形成せず、前記シアコッター７に代えて、両面に微細な凸状加工を施した摩擦板を前記両接合材２Ａ，２Ｂで挟み付けて、両接合材２Ａ，２Ｂを中ボルト３で締め付けて接合するように構成しても良い。これにより、ボルト接合部での緩みや滑りの発生を防止できる。この場合、前記摩擦板の一例として、例えば鉄板にプレスで孔加工することで、両面に微細な凸状となるバリを意図的に施したものを用いることができる。   In another reference example, a concave plate 6 is not formed in both the bonding materials 2A and 2B, and instead of the shear cotter 7, a friction plate having fine convex processing on both surfaces is used as the both bonding materials 2A. , 2B, and both the joining materials 2A, 2B may be fastened with the middle bolt 3 and joined. As a result, it is possible to prevent looseness and slippage at the bolt joint. In this case, as an example of the friction plate, it is possible to use, for example, an iron plate that is subjected to hole processing with a press so that burrs that have fine convex shapes are intentionally formed on both surfaces.
