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所定角度範囲で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 specifically, for example, in a displacement amplification type vibration damping device incorporated in a frame of a building or a structure, for connecting a brace member to a corner joining member so as to be rotatable within a predetermined angle range. The present invention relates to a joining apparatus.

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、従来は接合金物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 joint hardware. However, adjustment is difficult, and an excessive force may be applied to the member, and further, there is a problem that costs are increased.

図1は、この発明の実施形態を示す軸方向断面図、図2は分解斜視図、図3は図1のA−A線断面図である。この実施の形態は、この発明を変位増幅型制振装置におけるブレース部材1とコーナー用接合金物2との接合に適用した例である。ブレース部材1は可動側部材に該当し、またコーナー用接合金物2は架構のコーナー部に配置され、固定側部材に該当する。   1 is an axial sectional view showing an embodiment of the present invention, FIG. 2 is an exploded perspective view, and FIG. 3 is a sectional view taken along line AA of FIG. This embodiment is an example in which the present invention is applied to the joining of the brace member 1 and the corner fitting 2 in the displacement amplification type vibration damping device. The brace member 1 corresponds to a movable side member, and the corner joint hardware 2 is disposed at a corner portion of the frame and corresponds to a fixed side member.

接合装置はハンマー型ジョイント部材3、球状部材4、球面座5及び固定金物6を備えている。ハンマー型ジョイント部材3は軸部7を有し、この軸部7の先端にはT字形となるように円筒形のハンマー部8が形成されている。軸部7はその後部外周に形成されたねじ部9によってブレース部材1の内周に嵌合され、両者は軸方向に相対移動自在である。ブレース部材1の先方において軸部7の外周にねじ嵌合された部材10は止め金物である。この止め金物10を止めねじ25で軸部7に固定することにより、ブレース部材1に対してハンマー型ジョイント部材3が所定位置に固定される。   The joining apparatus includes a hammer type joint member 3, a spherical member 4, a spherical seat 5, and a fixed hardware 6. The hammer type joint member 3 has a shaft portion 7, and a cylindrical hammer portion 8 is formed at the tip of the shaft portion 7 so as to be T-shaped. The shaft portion 7 is fitted to the inner periphery of the brace member 1 by a screw portion 9 formed on the outer periphery of the rear portion, and both are relatively movable in the axial direction. A member 10 screwed to the outer periphery of the shaft portion 7 at the front end of the brace member 1 is a clasp. The hammer-type joint member 3 is fixed to a predetermined position with respect to the brace member 1 by fixing the metal fitting 10 to the shaft portion 7 with a set screw 25.

球状部材4はその直径を含む面で2分割された2つの分割球状部材4a,4aからなっている。各分割球状部材4aには分割面及び外周球面に開口する嵌合穴11が設けられ、また分割面には嵌合溝12が設けられている。これら嵌合穴11及び嵌合溝12を介して各分割球状部材4aは、ハンマー部8を含む軸部7の先端を包み込むように嵌合される。なお、ハンマー部8の両端面は球状部材4の外周球面と一致する凸状球面に形成されている。   The spherical member 4 is composed of two divided spherical members 4a and 4a which are divided into two by a plane including the diameter. Each divided spherical member 4a is provided with a fitting hole 11 that opens to the divided surface and the outer peripheral spherical surface, and a fitting groove 12 is provided on the divided surface. Each divided spherical member 4 a is fitted through the fitting hole 11 and the fitting groove 12 so as to wrap the tip of the shaft portion 7 including the hammer portion 8. Both end surfaces of the hammer portion 8 are formed as convex spherical surfaces that coincide with the outer peripheral spherical surface of the spherical member 4.

球状部材4が軸部7の先端に嵌合された状態で、嵌合溝12の内周面と軸部7との間に遊隙が形成される。これによりハンマー型ジョイント部材3は球状部材4に対してハンマー部8の軸線を中心として所定角度範囲で回動自在である。   A gap is formed between the inner peripheral surface of the fitting groove 12 and the shaft portion 7 in a state where the spherical member 4 is fitted to the tip of the shaft portion 7. Thereby, the hammer-type joint member 3 is rotatable with respect to the spherical member 4 within a predetermined angle range around the axis of the hammer portion 8.

球面座5は円筒形の部材であり、端部に上記球状部材4を受け入れる凹状球面13が形成されている。この球面座5はコーナー用接合金物2に形成された嵌合穴14に嵌合され、六角穴付きボルト15により固定される。   The spherical seat 5 is a cylindrical member, and a concave spherical surface 13 for receiving the spherical member 4 is formed at the end. The spherical seat 5 is fitted in a fitting hole 14 formed in the corner fitting 2 and fixed by a hexagon socket head bolt 15.

固定金物6も円筒形の部材であり、軸線を含む面で2分割された2つの分割円筒部材6a,6aからなっている。各分割円筒部材6aの内周には球状部材4を受け入れる凹状球面16と、これに連なる嵌合溝17が形成されている。嵌合溝17にはハンマー型ジョイント部材3の軸部7の先端が嵌合されるが、ハンマー型ジョイント部材3の回動を許容するように、嵌合溝17の内周面と軸部7との間には遊隙が形成される。各分割円筒部材6aはコーナー用接合金物2の嵌合穴14に嵌合され、外周に形成されたねじ部18により接合金物2に固定される。   The fixed hardware 6 is also a cylindrical member, and is composed of two divided cylindrical members 6a and 6a that are divided into two by a plane including the axis. A concave spherical surface 16 for receiving the spherical member 4 and a fitting groove 17 connected to the concave spherical surface 16 are formed on the inner periphery of each divided cylindrical member 6a. The tip of the shaft portion 7 of the hammer type joint member 3 is fitted into the fitting groove 17, and the inner peripheral surface of the fitting groove 17 and the shaft portion 7 are allowed to allow the hammer type joint member 3 to rotate. A gap is formed between the two. Each divided cylindrical member 6a is fitted into the fitting hole 14 of the corner metal fitting 2, and is fixed to the metal fitting 2 by a screw portion 18 formed on the outer periphery.

上記のような接合装置によれば、固定金物6を緩めておくことにより、球状部材4は球面座5上を全方向に関して自由に回転できる。したがって、施工誤差があってもブレース部材1の向きを自由に調整できる。そして、調整後、固定金物6を締め付けることにより、球状部材4を球面座5に向けて押圧し、所定位置に保持する。この結果、球状部材4は動かなくなるが、ハンマー型ジョイント部材3はハンマー部8の軸線を中心として回動自在であるので、従来のピンと同様に機能し、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。   According to the above joining apparatus, the spherical member 4 can freely rotate on the spherical seat 5 in all directions by loosening the fixed hardware 6. Therefore, even if there is a construction error, the direction of the brace member 1 can be freely adjusted. After the adjustment, the fixed metal member 6 is tightened to press the spherical member 4 toward the spherical seat 5 and hold it in a predetermined position. As a result, the spherical member 4 does not move, but the hammer-type joint member 3 is rotatable about the axis of the hammer portion 8, and thus functions in the same way as a conventional pin. Can perform as intended.

なお、固定金物6による固定後の球状部材4の動きを確実に止めるために、凹状球面13,16及び球状部材4の周面に粗面処理を施すようにしてもよい。   In order to reliably stop the movement of the spherical member 4 after being fixed by the fixed hardware 6, the concave spherical surfaces 13 and 16 and the peripheral surface of the spherical member 4 may be roughened.

図4は別の実施形態を示す軸方向断面図である。この実施形態は、ハンマー型ジョイント部材3の軸部7とブレース部材1との間に、内外周にねじ部19,20を有する調整金物21を嵌合させたものである。ねじ部19,20は互いに逆ねじとなっていて、調整金物21を回すことにより、ブレース部材1とハンマー型ジョイント部材3との相対位置を微調整することができる。   FIG. 4 is an axial cross-sectional view showing another embodiment. In this embodiment, an adjustment hardware 21 having screw portions 19 and 20 on the inner and outer circumferences is fitted between the shaft portion 7 of the hammer-type joint member 3 and the brace member 1. The screw portions 19 and 20 are reverse screws, and the relative position between the brace member 1 and the hammer-type joint member 3 can be finely adjusted by turning the adjustment hardware 21.

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 embodiment, the present invention is applied to the joining of a brace member and a corner fitting in a displacement amplification type vibration damping device incorporated in a building or structure. Applicable to general joining that is rotatable in an angular range.
