Description

この発明は、接合装置に関し、さらに詳細には、例えば建物や構造物の架構に組み込まれる変位増幅型制振装置において、コーナー用接合部材にブレース部材を回動自在に連結するための接合装置に関する。   The present invention relates to a joining device, and more particularly, to a joining device for rotatably connecting a brace member to a corner joining member in a displacement amplification type vibration damping device incorporated in a frame of a building or a structure, for example. .

制振技術の１つとして、建物や構造物の架構に組み込まれ、地震などの際に層間に生じる変位を増幅してダンパーに伝達する変位増幅型制振装置が知られている（例えば、特許文献１参照）。   As one of the vibration damping technologies, a displacement amplification type vibration damping device is known which is incorporated into a building or structure frame and amplifies the displacement generated between layers in the event of an earthquake and the like and transmits it to a damper (for example, a patent) Reference 1).

このような変位増幅型制振装置において、ブレース部材が架構のコーナー部に回動自在に連結されている。具体的には、コーナー部にブレース部材の接合金物を連結するためのブラケットを予め取り付けておき、このブラケットにピンを介して連結している。   In such a displacement amplification type vibration damping device, the brace member is rotatably connected to the corner portion of the frame. Specifically, a bracket for connecting a metal fitting of the brace member is attached in advance to the corner portion, and the bracket is connected to the bracket via a pin.

しかし、新築時の建物や構造物の架構には施工誤差が生じる。このような施工誤差が生じると、接合金物とブラケットとの連結部にピンを入れることが不可能になるなど、組み立てができなくなる場合がある。このため、従来はブラケットにライナーなどを挟むなどしてピンの位置を強制的に調整していた。しかし、調整は難しく、また部材に無理な力がかかる場合があり、さらにはコストもかかるという問題点を含んでいた。
特開平１０−１６９２４４号公報 However, construction errors occur in the construction of a new building or structure. When such a construction error occurs, it may become impossible to assemble, for example, it becomes impossible to insert a pin into the connecting portion between the metal joint and the bracket. For this reason, conventionally, the position of the pin has been forcibly adjusted by inserting a liner or the like between the brackets. However, adjustment is difficult, and an excessive force may be applied to the member, and further, there is a problem that costs are increased.
JP-A-10-169244

この発明は上記のような技術的背景に基づいてなされたものであって、次の目的を達成するものである。
この発明の目的は、施工誤差があっても部材に無理な力を加えることなく簡単に調整することができ、コストも低廉で済む接合装置を提供することにある。 The present invention has been made based on the technical background as described above, and achieves the following object.
An object of the present invention is to provide a joining device that can be easily adjusted without applying an excessive force to a member even if there is a construction error, and that can be manufactured at a low cost.

この発明は上記課題を達成するために、次のような手段を採用している。
すなわち、この発明は、固定側部材に可動側部材をピンを介して回動可能に接合するための接合装置であって、
前記固定側部材及び可動側部材の一方は、ピン孔が対向してそれぞれ設けられた１対の一方の取付けプレートを有し、
前記固定側部材及び可動側部材の他方は、前記１対の取付けプレート間に配置され、ピン孔が設けられた１枚の他方の取付けプレートを有し、
前記ピンは、前記他方の取付けプレートのピン孔に嵌合され、両側に凸状球面を有する中央部材と、
前記一方の取付けプレートの各ピン孔に嵌合され、内側面に前記凸状球面と嵌合する凹状球面を有する１対の端部部材とからなり、
前記中央部材と前記１対の端部部材とを固定する緊締部材を備えてなることを特徴とする接合装置にある。 The present invention employs the following means in order to achieve the above object.
That is, this invention is a joining device for joining a movable side member to a fixed side member via a pin so that rotation is possible,
Wherein one of the fixed member and the movable member, the pin holes has one of the mounting plate pair respectively provided to face,
The other of the fixed side member and the movable side member is disposed between the pair of mounting plates and has one other mounting plate provided with a pin hole,
The pin is fitted in a pin hole of the other mounting plate, and a central member having convex spherical surfaces on both sides;
A pair of end members fitted into the pin holes of the one mounting plate and having a concave spherical surface fitted on the inner spherical surface with the convex spherical surface;
The joining apparatus includes a fastening member that fixes the center member and the pair of end members.

より具体的には、前記ピンを構成する前記中央部材及び前記１対の端部部材は、ピン軸線と一致する貫通孔がそれぞれ設けられ、前記緊締部材は前記貫通孔に挿通されるボルトからなり、前記中央部材に設けられた前記貫通孔は前記ボルトの径よりも大径である。   More specifically, the central member and the pair of end members constituting the pin are each provided with a through hole coinciding with the pin axis, and the fastening member is composed of a bolt inserted into the through hole. The through hole provided in the central member has a diameter larger than the diameter of the bolt.

また、この発明は、固定側部材に可動側部材をピンを介して回動可能に接合するための接合装置であって、
前記固定側部材及び可動側部材の一方は、ピン孔が対向してそれぞれ設けられた１対の取付けプレートを有し、
前記ピンは、前記固定側部材及び可動側部材の他方に設けられ、両側に凸状球面を有する球体からなる中央部材と、
前記各ピン孔に嵌合され、内側面に前記凸状球面と嵌合する凹状球面を有する１対の端部部材とからなり、
前記中央部材と前記１対の端部部材とを固定する緊締部材を備え、
前記緊締部材は、前記中央部材の外周において前記１対の端部部材間に螺着された複数のボルトからなることを特徴とする接合装置にある。 Moreover, this invention is a joining apparatus for joining a movable side member to a fixed side member via a pin so that rotation is possible,
One of the fixed side member and the movable side member has a pair of mounting plates provided with pin holes facing each other,
The pin is provided on the other of the fixed side member and the movable side member, and a central member made of a sphere having convex spherical surfaces on both sides;
A pair of end members fitted into the pin holes and having concave spherical surfaces fitted on the convex spherical surfaces on the inner surface;
A tightening member for fixing the central member and the pair of end members;
The fastening member is a joining apparatus characterized by comprising a plurality of bolts screwed between the pair of end members on the outer periphery of the central member.

この発明によれば、中央部材と端部部材とを固定する緊締部材を緩めておくことにより、両者は凸状球面と凹状球面とで嵌合されていて互いに球面上を移動可能であることから、相対回転が可能である。したがって、施工誤差があっても可動側部材の向きを自由に調整できる。調整後、緊締部材を締め付けると、中央部材と端部部材とが一体化し、可動側部材を固定側部材に回動可能に連結するピンとして機能する。   According to this invention, by loosening the tightening member that fixes the central member and the end member, both are fitted with the convex spherical surface and the concave spherical surface and can move on the spherical surface. Relative rotation is possible. Therefore, even if there is a construction error, the direction of the movable member can be freely adjusted. When the tightening member is tightened after the adjustment, the central member and the end member are integrated to function as a pin that rotatably connects the movable member to the fixed member.

以上のように、この発明によれば、施工誤差があっても部材に無理な力を加えることなく簡単に調整することができ、コストも低廉で済む。   As described above, according to the present invention, even if there is a construction error, it can be easily adjusted without applying an excessive force to the member, and the cost can be reduced.

この発明の実施形態を図面を参照しながら以下に説明する。図１は、この発明の実施形態を示す分解斜視図、図２はピンの軸方向断面図である。この実施形態は、この発明を変位増幅型制振装置におけるブレース部材とコーナー用接合金物との接合に適用した例である。先端に１対の取付けプレート１，１（クレビス）を有するブレース部材（全体は不図示）は可動側部材に該当し、また１枚の取付けプレート３からなる接合金物は固定側部材に該当する。   Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view showing an embodiment of the present invention, and FIG. 2 is an axial sectional view of a pin. This embodiment is an example in which the present invention is applied to joining of a brace member and a corner metal fitting in a displacement amplification type vibration damping device. A brace member (the whole is not shown) having a pair of mounting plates 1 and 1 (clevis) at the tip corresponds to a movable side member, and a joint metal consisting of one mounting plate 3 corresponds to a fixed side member.

１対の取付けプレート１，１には、対向位置にピン孔４がそれぞれ設けられている。また１枚の取付けプレート３にもピン孔２が設けられている。ピン５は中央部材７と、その両側に配置される１対の端部部材８，８とからなっている。中央部材７は中央が取付けプレート３のピン孔２に嵌合される円筒形をなし、両側には凸状球面９，９を有している。   Each of the pair of mounting plates 1 and 1 is provided with pin holes 4 at opposing positions. A pin hole 2 is also provided in one mounting plate 3. The pin 5 includes a central member 7 and a pair of end members 8 and 8 disposed on both sides thereof. The center member 7 has a cylindrical shape whose center is fitted into the pin hole 2 of the mounting plate 3, and has convex spherical surfaces 9 and 9 on both sides.

各端部部材８は１対の取付けプレート１，１のピン孔４に嵌合される円筒形の部材で、内側面に中央部材７の凸状球面９に嵌合する凹状球面１１を有している。中央部材７及び端部部材８，８には、ピン軸線と一致する貫通孔１０，１２がそれぞれ形成されている。これらの貫通孔１０，１２にはボルト１３が挿通され、中央部材７に形成された貫通孔１０はボルト１３の径よりも大径となっている。   Each end member 8 is a cylindrical member fitted into the pin hole 4 of the pair of mounting plates 1, 1, and has a concave spherical surface 11 fitted to the convex spherical surface 9 of the central member 7 on the inner surface. ing. The central member 7 and the end members 8 and 8 are formed with through holes 10 and 12 that coincide with the pin axis, respectively. Bolts 13 are inserted into the through holes 10 and 12, and the through holes 10 formed in the central member 7 have a diameter larger than the diameter of the bolts 13.

可動側の取付けプレート１，１は固定側の取付けプレート３に次のようにして接合される。すなわち、取付けプレート１，１間に取付けプレート３が挟み込まれるようにして、ピン孔２とピン孔４とを位置合わせし、この状態で、中央部材７を一方のピン孔４を通して取付けプレート３のピン孔２に嵌合させる。次いで、取付けプレート１，１の各ピン孔４に端部部材８を嵌合させる。これにより、中央部材７の凸状球面９と端部部材８の凹状球面１１とが互いに嵌合する。   The movable side mounting plates 1 and 1 are joined to the fixed side mounting plate 3 as follows. That is, the pin hole 2 and the pin hole 4 are aligned so that the mounting plate 3 is sandwiched between the mounting plates 1 and 1, and in this state, the central member 7 is passed through the one pin hole 4 to Fit into the pin hole 2. Next, the end members 8 are fitted into the pin holes 4 of the mounting plates 1 and 1. Thereby, the convex spherical surface 9 of the central member 7 and the concave spherical surface 11 of the end member 8 are fitted to each other.

次に、中央部材７及び端部部材８の貫通孔１０，１２にボルト１３を挿通して、その先端にナット１４を螺着し、ボルト１３を軽く締め込む。この状態で、中央部材７と端部部材８，８とは、ボルト１３の径と貫通孔１０の径との差による遊隙の範囲で、相対回転が可能である。すなわち、可動側の取付けプレート１，１と固定側の取付けプレート３とは、相対回転が可能であり、したがって施工誤差があっても調整することができる。   Next, the bolt 13 is inserted into the through holes 10 and 12 of the central member 7 and the end member 8, the nut 14 is screwed to the tip, and the bolt 13 is lightly tightened. In this state, the central member 7 and the end members 8, 8 can be rotated relative to each other within a range of clearance due to the difference between the diameter of the bolt 13 and the diameter of the through hole 10. That is, the movable-side mounting plates 1 and 1 and the fixed-side mounting plate 3 can be rotated relative to each other, and therefore can be adjusted even if there is a construction error.

そして、調整後、ボルト１３を締め付けることにより、端部部材８，８を中央部材７に向けて押圧する。この結果、これらの部材７，８が一体化し、一体化した部材７，８は文字通りピン５として機能し、変位増幅型制振装置は所期の目的どおりの性能を発揮することができる。   Then, after the adjustment, the end members 8 and 8 are pressed toward the central member 7 by tightening the bolt 13. As a result, these members 7 and 8 are integrated, and the integrated members 7 and 8 literally function as the pins 5, and the displacement amplification type vibration damping device can exhibit the intended performance.

図３は別の実施形態を示す分解斜視図、図４はピンの軸方向断面図である。この実施形態において、可動側部材であるブレース部材は軸部１５の先端に一体に設けられた球体７を有し、この球体７がピン５の中央部材を構成している。固定側部材である接合金物は、対向位置にピン孔２，２が設けられた１対の取付けプレート３，３からなっている。   FIG. 3 is an exploded perspective view showing another embodiment, and FIG. 4 is an axial sectional view of the pin. In this embodiment, the brace member, which is a movable member, has a sphere 7 integrally provided at the tip of the shaft portion 15, and this sphere 7 constitutes the central member of the pin 5. The metal fitting as a fixed member is composed of a pair of mounting plates 3 and 3 provided with pin holes 2 and 2 at opposing positions.

中央部材７とともにピン５の構成部材である端部部材８，８は、１対の取付けプレート３，３の各ピン孔２に嵌合される円筒形の部材で、内側面に球体７の周面に嵌合する凹状球面１１を有している。一方の端部部材８には外側端面の外周縁部からピン軸線と平行にボルトを挿通するための貫通孔１７が複数設けられ、他方の端部部材８には貫通孔１７と対応してボルト孔１８が設けられている。また、各端部部材８の内側端面には、軸部１５の回動を許容するための逃げ溝１９がそれぞれ形成されている。   The end members 8 and 8 which are the components of the pin 5 together with the central member 7 are cylindrical members fitted into the pin holes 2 of the pair of mounting plates 3 and 3, It has a concave spherical surface 11 that fits into the surface. One end member 8 is provided with a plurality of through-holes 17 for inserting bolts from the outer peripheral edge of the outer end surface in parallel with the pin axis, and the other end member 8 has a bolt corresponding to the through-hole 17. A hole 18 is provided. In addition, on the inner end face of each end member 8, a relief groove 19 for allowing the shaft portion 15 to rotate is formed.

この実施形態の場合も、ボルト２０を軽く締め込んだ状態で、中央部材７と端部部材８，８とは、逃げ溝１９が効く範囲で、相対回転が可能である。すなわち、可動側の軸部１５と固定側の取付けプレート３，３とは、相対回転が可能であり、したがって施工誤差があっても調整することができる。そして、調整後、ボルト２０を締め付けることにより、端部部材８，８を中央部材７に向けて押圧すると、これらの部材７，８が一体化する。一体化した部材７，８は、可動側部材の軸部１５を固定側部材の取付けプレート３，３に回動可能に連結するピン５として機能する。   In the case of this embodiment as well, the central member 7 and the end members 8 and 8 can rotate relative to each other within a range in which the escape groove 19 is effective with the bolt 20 lightly tightened. That is, the movable-side shaft portion 15 and the fixed-side mounting plates 3 and 3 can be rotated relative to each other, and therefore can be adjusted even if there is a construction error. Then, after the adjustment, when the end members 8 and 8 are pressed toward the central member 7 by tightening the bolts 20, the members 7 and 8 are integrated. The integrated members 7 and 8 function as pins 5 that rotatably connect the shaft portion 15 of the movable side member to the mounting plates 3 and 3 of the fixed side member.

なお、上記２つの実施形態とも、中央部材７と端部部材８との固定後における両者の相対的な動きを確実に止めるために、球面９，１１や球体７の周面に粗面処理を施すようにしてもよい。   In both of the above-described two embodiments, the spherical surfaces 9 and 11 and the peripheral surface of the sphere 7 are subjected to rough surface treatment in order to reliably stop the relative movement between the central member 7 and the end member 8 after being fixed. You may make it give.

上記実施形態は例示にすぎず、この発明は種々の態様を採ることができる。例えば、上記実施形態は、この発明を建物や構造物に組み込まれる変位増幅型制振装置におけるブレース部材とコーナー用接合金物との接合に適用したものであるが、施工誤差を吸収したうえで所定角度範囲で回動自在とする接合一般に適用できる。   The above embodiment is merely an example, and the present invention can take various aspects. For example, in the above-described embodiment, the present invention is applied to joining of a brace member and a corner fitting in a displacement amplification type vibration damping device incorporated in a building or a structure. Applicable to general joining that is rotatable in an angular range.
