Description

本発明は、吊材によって吊り下げられた質量体が振り子運動をすることで建物の振動を抑える制震装置に関する。   The present invention relates to a vibration control device that suppresses vibration of a building by a pendulum movement of a mass body suspended by a suspension member.

従来、このような分野の技術としては、特開平４−４３３５号公報がある。この公報には、４本の脚部と、４本の脚部の上端を連結する上枠と、上枠からワイヤによって吊り下げられたマスとを備えた振子式制震装置が開示されている。この振子式制震装置において、マスの上面はロッドによって上枠の下面と接続されており、ロッドの側面と脚部の側面との間には緩衝器（ダンパ）とバネが配置されている。この振子式制震装置では、地震で建物が揺れるとマスが振り子運動をすると共にダンパが伸縮するので建物の揺れが抑えられる。バネはロッドに対して放射状に４個設けられており、各バネのバネ定数を調整することによって、建物の揺れ方向に対応した固有周期の調整がなされている。   Conventionally, as a technique in such a field, there is JP-A-4-4335. This gazette discloses a pendulum type vibration control device including four leg portions, an upper frame connecting the upper ends of the four leg portions, and a mass suspended from the upper frame by a wire. . In this pendulum type vibration control device, the upper surface of the mass is connected to the lower surface of the upper frame by a rod, and a shock absorber (damper) and a spring are disposed between the side surface of the rod and the side surface of the leg portion. In this pendulum type vibration control device, when the building is shaken by an earthquake, the mass performs a pendulum motion and the damper expands and contracts, so that the building can be prevented from shaking. Four springs are provided radially with respect to the rod, and the natural period corresponding to the shaking direction of the building is adjusted by adjusting the spring constant of each spring.

特開平４−４３３５号公報JP-A-4-4335

しかしながら、前述したように各バネのバネ定数を調整して建物の固有周期を調整する場合、バネ定数が異なる複数のバネを配置するためのスペースが装置内部で必要となるので、装置内部の構成が複雑化するという課題があった。   However, as described above, when the natural period of a building is adjusted by adjusting the spring constant of each spring, a space for arranging a plurality of springs having different spring constants is required inside the apparatus. There was a problem of increasing complexity.

本発明は、簡易な構成で周期の調整が行える制震装置を提供することを目的とする。   An object of the present invention is to provide a vibration control device capable of adjusting a cycle with a simple configuration.

本発明の制震装置は、支持架構から吊材で吊り下げられた質量体が振り子運動をすることによって建物の振動を減衰させる制震装置において、並置される複数の吊材と質量体とを連結させる連結部材と、複数の吊材を含む第１の鉛直面に直交する第１の軸線を中心として連結部材を各吊材に回転自在に接続する第１の接続部と、第１の鉛直面に対して垂直な第２の鉛直面に直交する第２の軸線を中心として連結部材を質量体に回転自在に接続する第２の接続部と、を備えたことを特徴とする。   A seismic control device of the present invention is a seismic control device that damps vibrations of a building by a pendulum movement of a mass body suspended from a support frame by a suspension material. A connecting member to be connected, a first connecting portion that rotatably connects the connecting member to each suspension member around a first axis orthogonal to a first vertical plane including a plurality of suspension members, and a first vertical portion And a second connecting portion that rotatably connects the connecting member to the mass body about a second axis perpendicular to the second vertical plane perpendicular to the plane.

ところで、水平面上における建物の剛性や形状が建物の揺れ方向ごとに異なることに起因して、地震が発生した場合における建物の固有周期も揺れ方向ごとに異なる。例えば、一方の揺れ方向における建物の剛性が高く他方の揺れ方向における建物の剛性が低い場合には、一方の揺れ方向における建物の固有周期が短くなると共に他方の揺れ方向における建物の固有周期が長くなる。また、質量体を振り子運動させて建物の揺れを抑える制震装置で揺れを効果的に抑えるには、質量体の固有周期を建物の固有周期に合わせることが好ましい。よって、揺れ方向ごとに異なる建物の固有周期に、揺れ方向ごとに質量体の固有周期を合わせれば、建物の揺れをより効果的に抑えることが可能となる。また、一般的に、質量体の固有周期を変えるには、質量体が振れる吊り長さ（質量体の振れ長さ）を変えればよい。   By the way, due to the fact that the rigidity and shape of the building on the horizontal plane differ for each shaking direction of the building, the natural period of the building when an earthquake occurs also differs for each shaking direction. For example, if the building stiffness in one shaking direction is high and the building stiffness in the other shaking direction is low, the building natural period in one shaking direction is shortened and the building natural period in the other shaking direction is long. Become. Further, in order to effectively suppress shaking with a vibration control device that suppresses shaking of the building by pendulum movement of the mass body, it is preferable to match the natural period of the mass body with the natural period of the building. Therefore, if the natural period of the mass body is matched with the natural period of the building that is different for each shaking direction, the shaking of the building can be more effectively suppressed. In general, in order to change the natural period of the mass body, the suspension length (the deflection length of the mass body) by which the mass body swings may be changed.

上記のような事情を踏まえて本発明の制震装置では、支持架構から吊り下げられた複数の吊材と質量体とを連結する連結部材を備えており、連結部材は、複数の吊材に対して第１の鉛直面に直交する第１の軸線回りに回転可能となっており、質量体に対して第２の鉛直面に直交する第２の軸線回りに回転可能となっている。よって、建物の第１の軸線方向の揺れに対しては、質量体は吊材と連結部材の合計長さを振れ長さとして揺動し、建物の第２の軸線方向の揺れに対しては、質量体と連結部材が吊材の長さを振れ長さとして揺動する。このように、揺れ方向が第１の軸線方向である場合は質量体が吊材と連結部材の合計長さを振れ長さとして揺動し、揺れ方向が第２の軸線方向である場合は質量体と連結部材が吊材の長さを振れ長さとして揺動するので、第１の軸線方向と第２の軸線方向とで質量体の振れ長さを変えることができる。よって、第１の軸線方向と第２の軸線方向とで質量体の振れ長さを変えることにより、第１の軸線方向と第２の軸線方向とで質量体の固有周期を変えることができる。以上のように、本発明の制震装置では、簡易な構成をもって制震を図ることができる。   In view of the circumstances as described above, the vibration damping device of the present invention includes a connecting member that connects a plurality of suspension members suspended from a support frame and a mass body, and the connection member includes a plurality of suspension members. On the other hand, it can rotate around a first axis perpendicular to the first vertical plane, and can rotate around a second axis perpendicular to the second vertical plane relative to the mass body. Therefore, the mass body swings with the total length of the suspension member and the connecting member as the swing length for the first axial swing of the building, and for the second axial swing of the building. The mass body and the connecting member swing with the length of the suspension member as the swing length. As described above, when the swing direction is the first axial direction, the mass body swings with the total length of the suspension member and the connecting member as the swing length, and when the swing direction is the second axial direction, the mass Since the body and the connecting member swing with the length of the suspension member as the swing length, the swing length of the mass body can be changed between the first axial direction and the second axial direction. Therefore, by changing the deflection length of the mass body between the first axis direction and the second axis direction, the natural period of the mass body can be changed between the first axis direction and the second axis direction. As described above, the vibration control device of the present invention can achieve vibration control with a simple configuration.

また、本発明の制震装置は、支持架構から吊材で吊り下げられた質量体が振り子運動をすることによって建物の振動を減衰させる制震装置において、支持架構と並置される複数の吊材とを連結させる連結部材と、複数の吊材を含む第１の鉛直面に直交する第１の軸線を中心として連結部材を各吊材に回転自在に接続する第１の接続部と、第１の鉛直面に対して垂直な第２の鉛直面に直交する第２の軸線を中心として連結部材を支持架構に回転自在に接続する第２の接続部と、を備えたことを特徴とする。   Further, the vibration control device of the present invention includes a plurality of suspension members juxtaposed with the support frame in the vibration control device that attenuates the vibration of the building by the pendulum motion of the mass body suspended from the support frame by the suspension material. A first connecting portion for connecting the connecting member to each suspension member rotatably around a first axis orthogonal to a first vertical plane including a plurality of suspension members; And a second connecting portion that rotatably connects the connecting member to the support frame about a second axis perpendicular to the second vertical plane perpendicular to the vertical plane.

本発明の制震装置では、支持架構と複数の吊材とを連結する連結部材を備えており、連結部材は、複数の吊材に対して第１の鉛直面に直交する第１の軸線回りに回転可能となっており、質量体に対して第１の鉛直面に対して垂直な第２の鉛直面に直交する第２の軸線回りに回転可能となっている。よって、建物の第１の軸線方向の揺れに対しては、支持架構に対して質量体は吊材と連結部材の合計長さを振れ長さとして揺動し、建物の第２の軸線方向の揺れに対しては、支持架構と連結部材に対して質量体が吊材の長さで揺動する。このように、揺れ方向が第１の軸線方向である場合は質量体が吊材と連結部材の合計長さを振れ長さとして揺動し、揺れ方向が第２の軸線方向である場合は質量体が吊材の長さで揺動するので、第１の軸線方向と第２の軸線方向とで質量体の振れ長さを変えることができる。よって、上記同様、第１の水平方向と第２の水平方向とで質量体の固有周期を変えることができ、簡易な構成をもって制震を図ることができる。   The vibration damping device of the present invention includes a connecting member that connects the support frame and the plurality of suspension members, and the connection member is around the first axis perpendicular to the first vertical plane with respect to the plurality of suspension members. And is rotatable around a second axis perpendicular to the second vertical plane perpendicular to the first vertical plane with respect to the mass body. Therefore, for the swing in the first axial direction of the building, the mass body swings with the total length of the suspension member and the connecting member as the swing length with respect to the support frame, and in the second axial direction of the building. For shaking, the mass body swings with the length of the suspension member with respect to the support frame and the connecting member. As described above, when the swing direction is the first axial direction, the mass body swings with the total length of the suspension member and the connecting member as the swing length, and when the swing direction is the second axial direction, the mass Since the body swings with the length of the suspension member, the deflection length of the mass body can be changed between the first axial direction and the second axial direction. Accordingly, as described above, the natural period of the mass body can be changed between the first horizontal direction and the second horizontal direction, and vibration control can be achieved with a simple configuration.

また、本発明の制震装置は、支持架構から吊り下げられた第１の吊材と第１の吊材の下端に連結された第２の吊材とによって吊り下げられた質量体が振り子運動をすることによって建物の振動を減衰させる制震装置において、並置される複数の第１の吊材と並置される複数の第２の吊材とを連結させる連結部材と、複数の第１の吊材と複数の第２の吊材とを含む鉛直面に直交する軸線を中心として連結部材を各吊材に回転自在に接続する接続部と、を備えたことを特徴とする。   In the vibration control device according to the present invention, the mass body suspended by the first suspension member suspended from the support frame and the second suspension member coupled to the lower end of the first suspension member has a pendulum motion. And a plurality of first suspension members connected to the plurality of first suspension members arranged side by side and the plurality of second suspension members arranged side by side. And a connecting portion that rotatably connects the connecting member to each suspension member about an axis perpendicular to a vertical plane including the member and the plurality of second suspension members.

本発明の制震装置では、複数の第１の吊材と複数の第２の吊材とを連結する連結部材を備えており、連結部材は、第１及び第２の吊材を含む鉛直面に直交する軸線を中心として第１の吊材及び第２の吊材のそれぞれに対して回転可能となっている。よって、建物の揺れが上記の軸線方向である場合には、支持架構に対して第１及び第２の吊材と連結部材が共に揺動し、上記鉛直面に対して垂直な鉛直面を直交する直交方向の建物の揺れに対しては、支持架構に対して第１及び第２の吊材のみが揺動する。このように、揺れ方向が軸線方向である場合は第１及び第２の吊材と連結部材の両方が移動し、揺れ方向が直交方向である場合は第１及び第２の吊材のみが移動するので、軸線方向と直交方向とで質量体の振れ長さを変えることができる。よって、上記同様、第１の水平方向と第２の水平方向とで質量体の固有周期を変えることができ、簡易な構成をもって制震を図ることができる。   The vibration damping device of the present invention includes a connecting member that connects the plurality of first suspension members and the plurality of second suspension members, and the connection member includes a vertical surface including the first and second suspension members. The first suspension member and the second suspension member are rotatable about an axis perpendicular to the first suspension member. Therefore, when the shaking of the building is in the above axial direction, the first and second suspension members and the connecting member swing together with respect to the support frame, and the vertical plane perpendicular to the vertical plane is orthogonal to the vertical plane. For the shaking of the building in the orthogonal direction, only the first and second suspension members swing with respect to the support frame. Thus, when the swing direction is the axial direction, both the first and second suspension members and the connecting member move, and when the swing direction is the orthogonal direction, only the first and second suspension members move. Therefore, the deflection length of the mass body can be changed between the axial direction and the orthogonal direction. Accordingly, as described above, the natural period of the mass body can be changed between the first horizontal direction and the second horizontal direction, and vibration control can be achieved with a simple configuration.

本発明によれば、装置内部の構成を簡易にすると共に、容易に組み立て作業を行うことができる。   According to the present invention, the internal configuration of the apparatus can be simplified and the assembly work can be easily performed.

以下、図面を参照しつつ本発明に係る制震装置の好適な実施形態について詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of a vibration control device according to the present invention will be described in detail with reference to the drawings.

図１及び図３に示されるように、地震や風による建物の揺れを抑える制震装置１は、ワイヤ（吊材）２に吊り下げられた錘（質量体）３を備えており、建物が揺れたときに錘３が振り子運動をすることによって建物の振動を減衰させる。制震装置１は、建物から上方に延在する柱５Ａと、柱５Ａの上端を架け渡す梁５Ｂとを有する支持架構５を備えており、錘３は、支持架構５の梁５Ｂから下方に延びる複数（この場合は４本）のワイヤ２で吊り下げられている。   As shown in FIG. 1 and FIG. 3, a vibration control device 1 that suppresses shaking of a building due to an earthquake or wind includes a weight (mass body) 3 suspended from a wire (hanging material) 2. The weight 3 attenuates the vibration of the building by the pendulum movement when it is shaken. The vibration control device 1 includes a support frame 5 having a column 5A that extends upward from the building and a beam 5B that bridges the upper end of the column 5A, and the weight 3 extends downward from the beam 5B of the support frame 5. It is suspended by a plurality of (in this case, four) wires 2 that extend.

図１及び図２に示されるように、錘３の揺れ時にワイヤ２を支持するための吊材支持構造１００において、梁５Ｂにはワイヤ２の上端が取り付けられている。この取付けに当たって、受圧部材１０が利用される。この受圧部材１０には、ワイヤ２の上端が貫通する吊材挿通孔１１が形成され、この吊材挿通孔１１を形成する壁面１１ａは、上下方向に延在すると共に、下方に行くに従って徐々に広がるような円弧の回転体形状を有している。そして、錘３の揺れに際して、ワイヤ２は壁面１１ａに沿って変形する。   As shown in FIGS. 1 and 2, in the suspension material support structure 100 for supporting the wire 2 when the weight 3 swings, the upper end of the wire 2 is attached to the beam 5B. In this attachment, the pressure receiving member 10 is used. The pressure receiving member 10 is formed with a suspension material insertion hole 11 through which the upper end of the wire 2 penetrates. A wall surface 11a forming the suspension material insertion hole 11 extends in the vertical direction and gradually decreases downward. It has an arcuate rotating body shape that expands. When the weight 3 swings, the wire 2 is deformed along the wall surface 11a.

受圧部材１０は、樹脂又は金属からなる円柱形状をなすと共に、吊材挿通孔１１を含んで上下方向に延在する分割面をもって分割されている。つまり、受圧部材１０は、第１の受圧半部１０Ａと第２の受圧半部１０Ｂとからなる。このような構成を採用すると、支持架構５の梁５Ｂにワイヤ２を吊り下げた状態で、第１の受圧半部１０Ａと第２の受圧半部１０Ｂとを分割面で合わせるようにして、吊材挿通孔１１内にワイヤ２をセットすることができる。このような作業は、ワイヤ２に受圧部材１０を容易に取り付けることができ、受圧部材１０の取付け作業性の向上が図られている。また、ワイヤ２を吊り下げたまま受圧部材１０の交換が可能になる。   The pressure receiving member 10 has a cylindrical shape made of resin or metal, and is divided with a dividing surface including the suspension material insertion hole 11 and extending in the vertical direction. In other words, the pressure receiving member 10 includes the first pressure receiving half 10A and the second pressure receiving half 10B. When such a configuration is adopted, the first pressure receiving half 10A and the second pressure receiving half 10B are aligned with each other in the state where the wire 2 is suspended from the beam 5B of the support frame 5, and the suspension is performed. The wire 2 can be set in the material insertion hole 11. In such an operation, the pressure receiving member 10 can be easily attached to the wire 2, and the workability of attaching the pressure receiving member 10 is improved. Further, the pressure receiving member 10 can be replaced while the wire 2 is suspended.

このような受圧部材１０は、ケース（不図示）の内部に収容される。ケースは、支持架構５の梁５Ｂの下面に固定される。また、ケースの下端には、ケースに形成された開口部を塞ぐ着脱自在な受圧部材用脱落防止部材（不図示）が取り付けられている。脱落防止部材は、ケースの下端から内方に突出する部材であれば、リング状の部材であっても、複数の爪形状の部材であっても良い。なお、脱落防止部材がリング状の場合は、着脱を容易にするために分割されている。このような構成を採用すると、ケースから脱落防止部材を取り除くことで受圧部材１０をケースの開口部から下方へ取り出すことができる。これによって、受圧部材１０における吊材挿通孔１１の壁面１１ａが長期の使用により摩耗した場合でも、受圧部材１０自体の交換を可能にしている。   Such a pressure receiving member 10 is accommodated in a case (not shown). The case is fixed to the lower surface of the beam 5 </ b> B of the support frame 5. In addition, a removable pressure receiving member drop-off preventing member (not shown) that closes an opening formed in the case is attached to the lower end of the case. The drop-off preventing member may be a ring-shaped member or a plurality of claw-shaped members as long as the member protrudes inward from the lower end of the case. In addition, when the drop-off preventing member is ring-shaped, it is divided for easy attachment / detachment. If such a structure is employ | adopted, the pressure receiving member 10 can be taken out from the opening part of a case by removing a drop-off prevention member from a case. Thereby, even when the wall surface 11a of the suspension member insertion hole 11 in the pressure receiving member 10 is worn out due to long-term use, the pressure receiving member 10 itself can be replaced.

また、ワイヤ２の上端には、支圧ソケット１７が固定され、この支圧ソケット１７は、梁５Ｂに形成された貫通孔を下から通すことができるが、このとき、支圧ソケット１７は、梁５Ｂの上面にネジを介して固定されるフランジ部１８によって、梁５Ｂの上側で保持されることになる。   In addition, a support socket 17 is fixed to the upper end of the wire 2, and the support socket 17 can pass through a through-hole formed in the beam 5B from below. At this time, the support socket 17 is It is held on the upper side of the beam 5B by the flange portion 18 fixed to the upper surface of the beam 5B via a screw.

この制震装置１の吊材支持構造１００において、受圧部材１０の吊材挿通孔１１の壁面１１ａは、下方に行くに従って徐々に広がるような回転体形状を有しているので、地震や強風により建物が揺れる度に錘（質量体）３が揺動すると、ワイヤ（吊材）２の上端も揺動する。このとき、ワイヤ２は吊材挿通孔１１の壁面１１ａに沿って変形する。そして、ワイヤ２が壁面１１ａに当たる接触面積は、錘３の振幅が大きくなる程、大きくなる。すなわち、錘（質量体）３の振れ力に応じてワイヤ２が壁面１１ａに当たる接触面積を増減させることができる。このように、錘３の揺れに対応して接触面積を変えることができるので、ワイヤ２の応力集中が起こり難くなり、これによってワイヤ２が切れ難くなるといった効果を奏する。ワイヤ２の鉛直荷重支持部（支圧ソケット１７）は、振れを生じず可動しないため、ワイヤフックのような摩耗を生じない。また、回転する部分がないため揺動時に抵抗を生じることがなくなり、振れ特性への影響をなくすことができる。   In the suspension material support structure 100 of the vibration control device 1, the wall surface 11 a of the suspension material insertion hole 11 of the pressure receiving member 10 has a rotating body shape that gradually spreads downward. When the weight (mass body) 3 swings whenever the building swings, the upper end of the wire (suspending material) 2 also swings. At this time, the wire 2 is deformed along the wall surface 11 a of the suspension member insertion hole 11. The contact area where the wire 2 hits the wall surface 11a increases as the amplitude of the weight 3 increases. That is, the contact area where the wire 2 hits the wall surface 11a can be increased or decreased according to the deflection force of the weight (mass body) 3. As described above, since the contact area can be changed in response to the swing of the weight 3, the stress concentration of the wire 2 is less likely to occur, and thus the wire 2 is hardly broken. Since the vertical load support portion (supporting socket 17) of the wire 2 does not move and does not move, it does not wear like a wire hook. Further, since there is no rotating part, no resistance is generated during swinging, and the influence on the swing characteristics can be eliminated.

ところで、制震装置１では、上述したワイヤ２と、ワイヤ２及び錘３を連結するための連結部材２０とを備えることにより、Ｘ方向（第２の軸線Ｂの方向）とＹ方向（第１の軸線Ａの方向）とで錘３の振れ長さを変更可能となっている。ここで、Ｙ方向とは支持架構５の梁５Ｂが延在する水平方向であり、Ｘ方向とはＹ方向に対して直交する水平方向である。   By the way, in the damping device 1, by providing the wire 2 mentioned above and the connection member 20 for connecting the wire 2 and the weight 3, the X direction (the direction of the second axis B) and the Y direction (the first direction) The swing length of the weight 3 can be changed in the direction of the axis A). Here, the Y direction is a horizontal direction in which the beam 5B of the support frame 5 extends, and the X direction is a horizontal direction orthogonal to the Y direction.

Ｘ方向に並設された２本のワイヤ２の下端には、２本のワイヤ２と錘３とを連結するための連結部材２０が第１の接続部３０を介して接続されている。また、連結部材２０の下端は第２の接続部４０を介して錘３に接続されている。各連結部材２０は、矩形の枠部２１を有しており、枠部２１の対角線上には２本の補強部材２２が延在している。各補強部材２２の端部は、枠部２１隅部で溶接されたガセットプレート２３にピン接合されている。   A connecting member 20 for connecting the two wires 2 and the weight 3 is connected to the lower ends of the two wires 2 arranged in parallel in the X direction via a first connecting portion 30. The lower end of the connecting member 20 is connected to the weight 3 via the second connection portion 40. Each connecting member 20 has a rectangular frame portion 21, and two reinforcing members 22 extend on the diagonal line of the frame portion 21. The end of each reinforcing member 22 is pin-bonded to a gusset plate 23 welded at the corner of the frame 21.

図２に示されるように、ワイヤ２と連結部材２０とを接続する第１の接続部３０は、枠部２１の上面から山状に突出するように枠部２１の上面に溶接された固定片３１と、Ｙ方向に挿通される軸ピン３２と、挿通された軸ピン３２を係合するピン受け部（不図示）とを備えている。また、ワイヤ２の下端はワイヤ２を接続部３０に接続するための保持部材２ａによって保持されており、この保持部材２ａには、軸ピン３２を挿通するための挿通孔がＹ方向に空けられている。ワイヤ２の保持部材２ａをＹ方向から挟むように２個の固定片３１がＹ方向に一対に枠部２１上に並設されており、これらの固定片３１にも軸ピン３２を挿通するための挿通孔がＹ方向に空けられている。   As shown in FIG. 2, the first connection portion 30 that connects the wire 2 and the connecting member 20 is a fixed piece welded to the upper surface of the frame portion 21 so as to protrude in a mountain shape from the upper surface of the frame portion 21. 31, a shaft pin 32 inserted in the Y direction, and a pin receiving portion (not shown) for engaging the inserted shaft pin 32. The lower end of the wire 2 is held by a holding member 2a for connecting the wire 2 to the connection portion 30, and an insertion hole for inserting the shaft pin 32 is opened in the Y direction in the holding member 2a. ing. Two fixed pieces 31 are juxtaposed on the frame portion 21 in the Y direction so as to sandwich the holding member 2a of the wire 2 from the Y direction, and the shaft pin 32 is also inserted through these fixed pieces 31. Is inserted in the Y direction.

軸ピン３２は、２個の固定片３１にワイヤ２の保持部材２ａを挟ませた状態で、一方の固定片３１の外側から軸ピン３２を上記各挿通孔にＹ方向に挿通し、他方の固定片３１の外側で軸ピン３２をピン受け部に係合させることにより、Ｙ方向に挿通された軸ピン３２は２個の固定片３１及びワイヤ２の保持部材２ａに固定される。このように軸ピン３２はＹ方向に挿通されて固定されるので、固定片３１が固定された枠部２１は、ワイヤ２に対してＹ方向に延在しＺＸ平面（第１の鉛直面）に直交する第１の軸線Ａを中心に回転自在に支持される。   The shaft pin 32 is inserted in the Y direction from the outside of one fixing piece 31 in the Y direction with the holding member 2a of the wire 2 sandwiched between the two fixing pieces 31, and the other pin By engaging the shaft pin 32 with the pin receiving portion on the outside of the fixed piece 31, the shaft pin 32 inserted in the Y direction is fixed to the two fixed pieces 31 and the holding member 2 a of the wire 2. Since the shaft pin 32 is inserted and fixed in the Y direction in this way, the frame portion 21 to which the fixing piece 31 is fixed extends in the Y direction with respect to the wire 2 and extends in the ZX plane (first vertical plane). Is supported so as to be rotatable about a first axis A perpendicular to the axis.

連結部材２０と錘３とを接続する第２の接続部４０は、錘３の上面から山状に突出するように錘３の上面に溶接された固定片４１と、枠部２１の下面から下方に突出するように枠部２１の下面に溶接された固定片４２と、Ｘ方向に挿通される軸ピン４３と、挿通された軸ピン４３を係合するピン受け部（不図示）とを備えている。錘３側の固定片４１は、枠部２１側の固定片４２をＸ方向から挟むように２個並設されており、固定片４１，４２のそれぞれには軸ピン４３を挿通するための挿通孔がＸ方向に空けられている。   The second connecting portion 40 that connects the connecting member 20 and the weight 3 includes a fixed piece 41 welded to the upper surface of the weight 3 so as to protrude in a mountain shape from the upper surface of the weight 3, and a lower side from the lower surface of the frame portion 21. A fixed piece 42 welded to the lower surface of the frame portion 21 so as to protrude in the X direction, a shaft pin 43 inserted in the X direction, and a pin receiving portion (not shown) for engaging the inserted shaft pin 43. ing. Two fixed pieces 41 on the weight 3 side are arranged side by side so as to sandwich the fixed piece 42 on the frame portion 21 side from the X direction, and each of the fixed pieces 41 and 42 is inserted to insert the shaft pin 43. A hole is made in the X direction.

軸ピン４３は、錘３側の固定片４１に枠部２１側の固定片４２を挟ませた状態で、一方の固定片４１の外側から軸ピン４３を上記各挿通孔にＸ方向に挿通し、他方の固定片４１の外側で軸ピン４３をピン受け部に係合させることにより、Ｘ方向に挿通された軸ピン４３は固定片４１，４２に固定される。このように軸ピン４３はＸ方向に挿通されて固定されるので、枠部２１は、錘３に対してＸ方向に延在しＹＺ平面（第２の鉛直面）に直交する第２の軸線Ｂを中心に回転自在に支持される。   The shaft pin 43 is inserted through the insertion holes in the X direction from the outside of one of the fixed pieces 41 with the fixed piece 42 on the side of the frame 21 sandwiched between the fixed piece 41 on the weight 3 side. The shaft pin 43 inserted in the X direction is fixed to the fixed pieces 41 and 42 by engaging the shaft pin 43 with the pin receiving portion outside the other fixed piece 41. Thus, since the shaft pin 43 is inserted and fixed in the X direction, the frame portion 21 extends in the X direction with respect to the weight 3 and is a second axis that is orthogonal to the YZ plane (second vertical surface). It is supported rotatably about B.

以上のように、第１の接続部３０を備えることによって、連結部材２０はワイヤ２に対してＺＸ平面に直交する第１の軸線Ａ回りに回転自在となっており、第２の接続部４０を備えることによって、連結部材２０は錘３に対してＹＺ平面に直交する第２の軸線Ｂ回りに回転自在となっている。   As described above, by providing the first connecting portion 30, the connecting member 20 can rotate about the first axis A orthogonal to the ZX plane with respect to the wire 2, and the second connecting portion 40. The connecting member 20 is rotatable about the second axis B perpendicular to the YZ plane with respect to the weight 3.

次に、地震や風で建物が揺れた場合におけるワイヤ２、錘３及び連結部材２０の動作について図２及び図３を参照しながら説明する。なお、図３は、便宜上一部の図示を簡略化している。まず、揺れ方向がＸ方向である場合における動作については、図３（ａ）及び図３（ｃ）に示されるように、錘３が支持架構５に対してＸ方向に移動する。このとき、ワイヤ２の上端は受圧部材１０の吊材挿通孔１１内でＸ方向に移動し、湾曲した壁面１１ａに滑らかに接触する。   Next, operations of the wire 2, the weight 3, and the connecting member 20 when the building is shaken by an earthquake or wind will be described with reference to FIGS. In FIG. 3, a part of the illustration is simplified for convenience. First, regarding the operation in the case where the shaking direction is the X direction, the weight 3 moves in the X direction with respect to the support frame 5, as shown in FIGS. 3 (a) and 3 (c). At this time, the upper end of the wire 2 moves in the X direction within the suspension member insertion hole 11 of the pressure receiving member 10, and smoothly contacts the curved wall surface 11a.

また、連結部材２０は、第１の接続部３０によって、２本のワイヤ２に対してＺＸ平面に直交する軸線Ａ回りに回転自在に接続されているので、揺れ方向がＸ方向である場合には、ワイヤ２は連結部材２０に対して軸線Ａ回りに回転する。一方、連結部材２０は、第２の接続部４０によって、錘３に対する軸線Ａ回りの回転は規制されているので、連結部材２０は錘３に対して回転しない。従って、揺れ方向がＸ方向である場合には、支持架構５に対してワイヤ２のみがＸ方向に傾き、錘３に対する連結部材２０の移動は規制されるので、吊材支持構造１００の受圧部材１０から連結部材２０上端の接続部３０までの長さが錘３の振れ長さＸ１となる。   Further, since the connecting member 20 is connected to the two wires 2 by the first connecting portion 30 so as to be rotatable around the axis A orthogonal to the ZX plane, the swaying direction is the X direction. The wire 2 rotates about the axis A with respect to the connecting member 20. On the other hand, since the connection member 20 is restricted from rotating around the axis A with respect to the weight 3 by the second connection portion 40, the connection member 20 does not rotate relative to the weight 3. Therefore, when the shaking direction is the X direction, only the wire 2 is inclined in the X direction with respect to the support frame 5 and the movement of the connecting member 20 with respect to the weight 3 is restricted. The length from 10 to the connecting portion 30 at the upper end of the connecting member 20 is the runout length X1 of the weight 3.

また、図３（ｂ）及び図３（ｄ）に示されるように、建物のＹ方向の揺れに対しては、ワイヤ２は支持架構５に対してＹ方向に傾く。このとき、ワイヤ２の上端は、揺れ方向がＸ方向である場合と同様に、受圧部材１０内部の壁面１１ａに滑らかに接触する。また、連結部材２０は、第１の接続部３０によってＹＺ平面に直交する軸線Ｂ回りの回転が規制されているので、揺れ方向がＹ方向である場合にはワイヤ２は連結部材２０に対して回転しない。一方、連結部材２０は、第２の接続部４０によって、錘３に対する軸線Ｂ回りの回転は許容されているので、連結部材２０は錘３に対して軸線Ｂ回りに回転する。従って、揺れ方向がＹ方向である場合には、支持架構５に対してワイヤ２と連結部材２０とがＹ方向に傾くので、吊材支持構造１００の受圧部材１０から連結部材２０下端の接続部４０までの長さが錘３の振れ長さＹ１となる。   Further, as shown in FIGS. 3B and 3D, the wire 2 is inclined in the Y direction with respect to the support frame 5 with respect to the shaking of the building in the Y direction. At this time, the upper end of the wire 2 smoothly contacts the wall surface 11a inside the pressure receiving member 10 as in the case where the shaking direction is the X direction. Further, since the rotation of the connecting member 20 around the axis B orthogonal to the YZ plane is restricted by the first connecting portion 30, the wire 2 is in relation to the connecting member 20 when the shaking direction is the Y direction. Does not rotate. On the other hand, since the connecting member 20 is allowed to rotate around the axis B with respect to the weight 3 by the second connecting portion 40, the connecting member 20 rotates around the axis B with respect to the weight 3. Therefore, when the swinging direction is the Y direction, the wire 2 and the connecting member 20 are inclined in the Y direction with respect to the support frame 5, so that the connecting portion at the lower end of the connecting member 20 from the pressure receiving member 10 of the hanging material support structure 100. The length up to 40 is the runout length Y1 of the weight 3.

以上のように、建物のＸ方向の揺れにおいては、吊材支持構造１００の受圧部材１０から連結部材２０上端の接続部３０までの長さが振れ長さＸ１となり、建物のＹ方向の揺れにおいては、吊材支持構造１００の受圧部材１０から連結部材２０下端の接続部４０までの長さが振れ長さＹ１となっている。よって、揺れ方向がＸ方向である場合における錘３の振れ長さＸ１は、揺れ方向がＹ方向である場合における錘３の振れ長さＹ１よりも短くなっている。従って、錘３におけるＸ方向の固有周期はＹ方向の固有周期よりも短くなっている。   As described above, in the swing of the building in the X direction, the length from the pressure receiving member 10 of the suspension material support structure 100 to the connection portion 30 at the upper end of the connecting member 20 is the swing length X1, and in the swing of the building in the Y direction. The length from the pressure receiving member 10 of the suspension material support structure 100 to the connecting portion 40 at the lower end of the connecting member 20 is the swing length Y1. Therefore, the swing length X1 of the weight 3 when the swing direction is the X direction is shorter than the swing length Y1 of the weight 3 when the swing direction is the Y direction. Therefore, the natural period in the X direction of the weight 3 is shorter than the natural period in the Y direction.

このように制震装置１では、支持架構５から吊り下げられた２本のワイヤ２と錘３とを連結する連結部材２０を備えており、連結部材２０は、ワイヤ２に対してＺＸ平面に直交しＹ方向に延在する第１の軸線Ａ回りに回転可能となっており、錘３に対してＹＺ平面に直交しＸ方向に延在する第２の軸線Ｂ回りに回転可能となっている。   As described above, the vibration damping device 1 includes the connecting member 20 that connects the two wires 2 suspended from the support frame 5 and the weight 3, and the connecting member 20 is in a ZX plane with respect to the wire 2. It is rotatable about a first axis A that is orthogonal and extends in the Y direction, and is rotatable about a second axis B that is orthogonal to the YZ plane and extends in the X direction with respect to the weight 3. Yes.

よって、建物のＹ方向の揺れに対しては、ワイヤ２と連結部材２０の両方が錘３に対して揺動し、建物のＸ方向の揺れに対しては、ワイヤ２が連結部材２０と錘３に対して揺動する。このように、揺れ方向がＹ方向である場合はワイヤ２と連結部材２０の両方が移動し、揺れ方向がＸ方向である場合はワイヤ２のみが移動するので、Ｘ方向とＹ方向とで錘３の振れ長さを変えることができ、上述したように、Ｘ方向とＹ方向とで錘３の固有周期を変えることができる。よって、制震装置１では、簡易な構成をもって制震を図ると共に、揺れ方向ごとに異なる建物の固有周期に、揺れ方向ごとに錘３の固有周期を合わせられるので、建物の揺れをより効果的に抑えることができる。   Therefore, both the wire 2 and the connecting member 20 are swung with respect to the weight 3 when the building is shaken in the Y direction, and the wire 2 is connected with the connecting member 20 and the weight when the building is shaken in the X direction. 3 swings. Thus, both the wire 2 and the connecting member 20 move when the shaking direction is the Y direction, and only the wire 2 moves when the shaking direction is the X direction. 3, and the natural period of the weight 3 can be changed between the X direction and the Y direction as described above. Therefore, the vibration control device 1 can control the vibration with a simple structure and can adjust the natural period of the weight 3 for each vibration direction to the natural period of the building that is different for each vibration direction. Can be suppressed.

また、制震装置１では、錘３に対する連結部材２０の高さを高くするとＸ方向における錘３の振れ長さＸ１が短くなり、錘３に対する連結部材２０の高さを低くするとＸ方向における錘３の振れ長さＸ１が長くなる。このように連結部材２０の高さを変えることでＸ方向における錘３の振れ長さを調整することができるので、Ｘ方向における錘３の固有周期を簡単に変えることができる。   Further, in the vibration control device 1, when the height of the connecting member 20 with respect to the weight 3 is increased, the deflection length X1 of the weight 3 in the X direction is shortened, and when the height of the connecting member 20 with respect to the weight 3 is decreased, the weight in the X direction is reduced. The runout length X1 of 3 becomes longer. Since the swing length of the weight 3 in the X direction can be adjusted by changing the height of the connecting member 20 in this way, the natural period of the weight 3 in the X direction can be easily changed.

（第２実施形態）
図４に示されるように、第２実施形態の制震装置５１が第１実施形態の制震装置１と異なる点は、２本のワイヤ２と錘３との間に設けられた連結部材２０に代えて、支持架構５と２本のワイヤ５２との間に設けられた連結部材７０を用いた点のみであるため、第２実施形態では第１実施形態と重複する説明を省略する。 (Second Embodiment)
As shown in FIG. 4, the vibration control device 51 of the second embodiment is different from the vibration control device 1 of the first embodiment in that the connecting member 20 provided between the two wires 2 and the weight 3. Instead of this, only the connection member 70 provided between the support frame 5 and the two wires 52 is used. Therefore, in the second embodiment, the description overlapping that of the first embodiment is omitted.

制震装置５１は、ワイヤ５２に吊り下げられた錘３と、支持架構５とを備えている。各ワイヤ５２は、吊材支持構造１００によって錘３の上端で支持されている。ワイヤ５２の上端は、第１の接続部８０を介して連結部材７０に接続されている。第１の接続部８０の構造は、図２に示される接続部３０の構造と同一であり、上下を逆にしただけなので詳細な説明を省略する。また、連結部材７０の構造も第１実施形態の連結部材２０の構造と同一である。   The vibration control device 51 includes a weight 3 suspended from a wire 52 and a support frame 5. Each wire 52 is supported at the upper end of the weight 3 by the suspension material support structure 100. The upper end of the wire 52 is connected to the connecting member 70 via the first connecting portion 80. The structure of the first connection portion 80 is the same as the structure of the connection portion 30 shown in FIG. 2, and the detailed description is omitted because it is simply upside down. Further, the structure of the connecting member 70 is the same as the structure of the connecting member 20 of the first embodiment.

連結部材７０の上端は、第２の接続部９０を介して支持架構５の梁５Ｂに接続されている。第２の接続部９０の構造は、図２に示される接続部４０の構造と同一であり、上下を逆にしただけである。よって、連結部材７０は、２本のワイヤ５２に対してＺＸ平面に直交しＹ方向に延在する軸線（第１の軸線）Ａ回りに回転自在に支持されており、支持架構５に対してＹＺ平面に直交しＸ方向に延在する軸（第２の軸線）Ｂ回りに回転自在に支持されている。   The upper end of the connecting member 70 is connected to the beam 5 </ b> B of the support frame 5 through the second connection portion 90. The structure of the second connection portion 90 is the same as the structure of the connection portion 40 shown in FIG. 2 and is simply upside down. Therefore, the connecting member 70 is supported by the two wires 52 so as to be rotatable about an axis (first axis) A orthogonal to the ZX plane and extending in the Y direction. It is rotatably supported around an axis (second axis) B that is orthogonal to the YZ plane and extends in the X direction.

次に、連結部材７０、ワイヤ２及び錘３の動作について説明する。まず、揺れ方向がＸ方向である場合における動作については、図４（ａ）及び図４（ｃ）に示されるように、ワイヤ５２が支持架構５と連結部材７０に対して軸線Ａ回りに回転する。一方、連結部材７０は、第２の接続部９０によって、支持架構５に対する軸線Ａ回りの回転は規制されているので、連結部材７０は支持架構５に対して回転しない。従って、揺れ方向がＸ方向である場合には、支持架構５及び連結部材７０に対してワイヤ５２のみがＸ方向に傾くので、連結部材７０下端の接続部８０から錘３上端の吊材支持構造１００までの長さが錘３の振れ長さＸ２となる。   Next, operations of the connecting member 70, the wire 2 and the weight 3 will be described. First, regarding the operation when the shaking direction is the X direction, the wire 52 rotates about the axis A with respect to the support frame 5 and the connecting member 70 as shown in FIGS. To do. On the other hand, since the rotation of the connecting member 70 around the axis A with respect to the support frame 5 is restricted by the second connecting portion 90, the connection member 70 does not rotate with respect to the support frame 5. Therefore, when the swinging direction is the X direction, only the wire 52 is inclined in the X direction with respect to the support frame 5 and the connecting member 70, so that the suspension support structure for the upper end of the weight 3 from the connection portion 80 at the lower end of the connecting member 70. The length up to 100 is the runout length X2 of the weight 3.

また、図４（ｂ）及び図４（ｄ）に示されるように、建物のＹ方向の揺れに対しては、連結部材７０が支持架構５に対してＹ方向に移動する。連結部材７０の下端は、第１の接続部８０によってＹＺ平面に直交する軸線Ｂ回りの回転が規制されているので、揺れ方向がＹ方向である場合には連結部材７０はワイヤ５２に対して回転しない。また、ワイヤ５２の下端は、揺れ方向がＸ方向である場合と同様に、吊材支持構造１００における受圧部材１０の壁面１１ａに滑らかに接触する。従って、揺れ方向がＹ方向である場合には、支持架構５に対して連結部材７０とワイヤ５２とがＹ方向に傾くので、支持架構５の下端の接続部９０から錘３上端の吊材支持構造１００までの長さが錘３の振れ長さＹ２となる。   Further, as shown in FIGS. 4B and 4D, the connection member 70 moves in the Y direction with respect to the support frame 5 with respect to the shaking of the building in the Y direction. Since the rotation of the lower end of the connecting member 70 about the axis B perpendicular to the YZ plane is restricted by the first connecting portion 80, the connecting member 70 is in relation to the wire 52 when the swinging direction is the Y direction. Does not rotate. In addition, the lower end of the wire 52 smoothly contacts the wall surface 11a of the pressure receiving member 10 in the hanging material support structure 100, as in the case where the shaking direction is the X direction. Accordingly, when the swinging direction is the Y direction, the connecting member 70 and the wire 52 are inclined in the Y direction with respect to the support frame 5, so that the suspension material support at the upper end of the weight 3 from the connection portion 90 at the lower end of the support frame 5. The length up to the structure 100 is the runout length Y2 of the weight 3.

以上、制震装置５１では、支持架構５と２本のワイヤ５２とを連結する連結部材７０を備えており、連結部材７０は、ワイヤ５２に対してＺＸ平面に直交する第１の軸線Ａ回りに回転可能となっており、支持架構５に対してＺＸ平面に対して垂直なＹＸ平面に直交する第２の軸線Ｂ回りに回転可能となっている。よって、第１の軸線Ａ方向（Ｙ方向）における建物の揺れに対しては、支持架構５に対して連結部材７０とワイヤ５２の両方が揺動し、第２の軸線Ｂ方向（Ｘ方向）における建物の揺れに対しては、支持架構５と連結部材７０に対してワイヤ５２が揺動する。   As described above, the vibration control device 51 includes the connecting member 70 that connects the support frame 5 and the two wires 52, and the connecting member 70 has the first axis A that is orthogonal to the ZX plane with respect to the wire 52. It can rotate around the second axis B orthogonal to the YX plane perpendicular to the ZX plane with respect to the support frame 5. Therefore, for the shaking of the building in the first axis A direction (Y direction), both the connecting member 70 and the wire 52 are swung with respect to the support frame 5, and the second axis B direction (X direction). In response to the shaking of the building, the wire 52 swings with respect to the support frame 5 and the connecting member 70.

このように、揺れ方向がＹ方向である場合はワイヤ５２と連結部材７０の両方が移動し、揺れ方向がＸ方向である場合はワイヤ５２のみが移動するので、Ｘ方向とＹ方向とで錘３の振れ長さを変えることができる。よって、第１実施形態と同様の効果が得られる。   Thus, both the wire 52 and the connecting member 70 move when the shaking direction is the Y direction, and only the wire 52 moves when the shaking direction is the X direction. The runout length of 3 can be changed. Therefore, the same effect as the first embodiment can be obtained.

（第３実施形態）
図５に示されるように、第３実施形態の制震装置２０１が第１実施形態の制震装置１と異なる点は、ワイヤ２に代えて、第１のワイヤ２０２とワイヤ２０２の下端に接続されたワイヤ２０３を用いた点と、２本のワイヤ２と錘３との間に設けられた連結部材２０に代えて、２本の第１のワイヤ２０２と２本の第２のワイヤ２０３との間に設けられた連結部材２２０を用いた点のみである。よって、第１実施形態と重複する部分についての説明は省略する。 (Third embodiment)
As shown in FIG. 5, the damping device 201 of the third embodiment is different from the damping device 1 of the first embodiment in that instead of the wire 2, the first wire 202 and the lower end of the wire 202 are connected. Instead of the connecting wire 20 provided between the two wires 2 and the weight 3, the two first wires 202 and the two second wires 203 are used. It is only the point which used the connection member 220 provided between these. Therefore, the description about the part which overlaps with 1st Embodiment is abbreviate | omitted.

制震装置２０１は、第２のワイヤ２０３に吊り下げられた錘３と、支持架構５とを備えており、ワイヤ２０３の下端は、吊材支持構造１００によって錘３に支持されている。また、各第１のワイヤ２０２の上端は、吊材支持構造１００によって支持架構５に支持されており、各第１のワイヤ２０２の下端は、第１の接続部２３０を介して連結部材２２０の上端に接続されている。第１の接続部２３０の構造は、図２に示される接続部３０の構造と同一である。また、第２のワイヤ２０３の上端は、第２の接続部２４０を介して連結部材２２０の下端に接続されている。第２の接続部２４０の構造は、図２に示される接続部３０の構造と同一であり、上下を逆にしただけなので詳細な説明を省略する。また、連結部材２２０の構造も第１実施形態の連結部材２０の構造と同一である。   The vibration control device 201 includes a weight 3 suspended from a second wire 203 and a support frame 5, and the lower end of the wire 203 is supported by the weight 3 by a suspension material support structure 100. Further, the upper end of each first wire 202 is supported by the support frame 5 by the suspension material support structure 100, and the lower end of each first wire 202 is connected to the connecting member 220 via the first connection portion 230. Connected to the top. The structure of the first connection part 230 is the same as the structure of the connection part 30 shown in FIG. In addition, the upper end of the second wire 203 is connected to the lower end of the coupling member 220 via the second connection portion 240. The structure of the second connecting portion 240 is the same as the structure of the connecting portion 30 shown in FIG. 2, and the detailed description is omitted because it is just upside down. Further, the structure of the connecting member 220 is the same as the structure of the connecting member 20 of the first embodiment.

よって、連結部材２２０の上端は、第１の接続部２３０を介して２本の第１のワイヤ２０２に接続されており、第１のワイヤ２０２に対してＹ方向に延在する軸線Ａ回りに回転自在に支持されている。連結部材２２０の下端も、連結部材２２０の上端と同様、軸線Ａ回りに回転自在に支持されている。   Therefore, the upper end of the connecting member 220 is connected to the two first wires 202 via the first connection portion 230, and is about the axis A extending in the Y direction with respect to the first wire 202. It is supported rotatably. The lower end of the connecting member 220 is also supported rotatably around the axis A, like the upper end of the connecting member 220.

次に、第１及び第２のワイヤ２０２，２０３、連結部材２２０並びに錘３の動作について説明する。まず、揺れ方向がＸ方向である場合における動作については、図５（ａ）及び図５（ｃ）に示されるように、第１のワイヤ２０２及び第２のワイヤ２０３が支持架構５と連結部材２２０に対して軸線Ａ回りに回転する。よって、揺れ方向がＸ方向である場合には、第１及び第２のワイヤ２０２，２０３が連結部材２２０に対して回転自在となっているので、支持架構５側の吊材支持構造１００から第１の接続部２３０までの長さＸ３１と、第２の接続部２４０から錘３側の吊材支持構造１００までの長さＸ３２との和が、錘３の振れ長さとなる。   Next, operations of the first and second wires 202 and 203, the connecting member 220, and the weight 3 will be described. First, regarding the operation when the shaking direction is the X direction, as shown in FIGS. 5A and 5C, the first wire 202 and the second wire 203 are connected to the support frame 5 and the connecting member. Rotate about axis A relative to 220. Therefore, when the shaking direction is the X direction, the first and second wires 202 and 203 are rotatable with respect to the connecting member 220. The sum of the length X31 from the first connecting portion 230 to the length X32 from the second connecting portion 240 to the suspension member support structure 100 on the weight 3 side is the swing length of the weight 3.

また、図５（ｂ）及び図５（ｄ）に示されるように、建物のＹ方向の揺れに対しては、第１及び第２の接続部２３０，２４０によって、第１及び第２のワイヤ２０２，２０３に対する連結部材２２０の第２の軸線Ｂを中心とした回転が規制される。よって、連結部材２２０は４本のワイヤ２０２，２０３に対して回転しない。従って、揺れ方向がＹ方向である場合には、支持架構５に対して４本のワイヤ２０２，２０３と連結部材２２０とが共にＹ方向に傾くので、支持架構５下端の吊材支持構造１００から錘３上端の吊材支持構造１００までの長さＹ３が錘３の振れ長さとなる。   Further, as shown in FIGS. 5B and 5D, the first and second wires 230 and 240 are used to sway the building in the Y direction. The rotation of the connecting member 220 with respect to 202 and 203 around the second axis B is restricted. Therefore, the connecting member 220 does not rotate with respect to the four wires 202 and 203. Therefore, when the swinging direction is the Y direction, the four wires 202 and 203 and the connecting member 220 are both inclined in the Y direction with respect to the support frame 5, so that the suspension material support structure 100 at the lower end of the support frame 5 The length Y3 from the upper end of the weight 3 to the suspension support structure 100 is the runout length of the weight 3.

以上、制震装置２０１においてもＸ方向とＹ方向とで錘３の振れ長さを変えることができるので、Ｘ方向とＹ方向とで錘３の固有周期を変えることができ、第１及び第２実施形態と同様の効果が得られる。   As described above, also in the vibration control device 201, the runout length of the weight 3 can be changed between the X direction and the Y direction. Therefore, the natural period of the weight 3 can be changed between the X direction and the Y direction. The same effect as in the second embodiment can be obtained.

本発明は、上述した実施形態に限定されず、本発明の要旨を逸脱しない範囲で種々の変形が可能である。   The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
