前記制振装置６は外形が矩形状をなすものであり、図１に示すように、外形を構成する矩形枠状の矩形フレーム６１と、この矩形フレーム６１に対向して設けられた一対の支持部６４，６４と、この一対の支持部６４，６４間に配置され、かつ該一対の支持部６４，６４によって支持された制振機構とを備えている。
矩形フレーム６１は、左右一対の縦フレーム６２，６２と、上下一対の横フレーム６３，６３とを矩形枠状に組み立てて形成されたものであり、縦フレーム６２の端部と横フレーム６３の端部はピン結合されている。したがって、矩形フレーム６１は左右方向に力が作用すると平行四辺形を形成するようにして変形可能となっている。なお、縦フレーム６２、横フレーム６３は鉄やアルミニウム等の金属で形成されている。
また、横フレーム６３には、後述する制振部材６７を備えた制振ボックス６９が取り付けられている。 The vibration damping device 6 has a rectangular outer shape, and as shown in FIG. 1, a rectangular frame 61 that forms the outer shape and a pair of supports provided to face the rectangular frame 61. And a vibration damping mechanism disposed between the pair of support portions 64 and 64 and supported by the pair of support portions 64 and 64.
The rectangular frame 61 is formed by assembling a pair of left and right vertical frames 62 and 62 and a pair of upper and lower horizontal frames 63 and 63 into a rectangular frame shape. The end of the vertical frame 62 and the end of the horizontal frame 63 are formed. The parts are pin-coupled. Therefore, the rectangular frame 61 can be deformed so as to form a parallelogram when a force acts in the left-right direction. The vertical frame 62 and the horizontal frame 63 are made of metal such as iron or aluminum.
Further, a vibration damping box 69 having a vibration damping member 67 described later is attached to the horizontal frame 63.

前記矩形フレーム６１は、一対の構造材７，７、上壁部８、下壁部９によって囲まれた部分に設けられ、これら一対の構造材７，７、上壁部８、下壁部９に固定されている。矩形フレーム６１を構成する縦フレーム６２は構造材７，７の内側を向く側面に接着剤や木ねじで固定され、上の横フレーム６２は上壁部８の下端面に、下の横フレーム６２が下壁部９の上端面に、それぞれ接着剤や木ねじで固定されている。   The rectangular frame 61 is provided in a portion surrounded by a pair of structural materials 7, 7, an upper wall portion 8, and a lower wall portion 9, and the pair of structural materials 7, 7, upper wall portion 8, lower wall portion 9. It is fixed to. The vertical frame 62 constituting the rectangular frame 61 is fixed to the side faces of the structural members 7, 7 with an adhesive or wood screws, the upper horizontal frame 62 is at the lower end surface of the upper wall portion 8, and the lower horizontal frame 62 is It is fixed to the upper end surface of the lower wall portion 9 with an adhesive or a wood screw.

前記制振機構は、前記一対の支持部６４，６４によって支持されて、該一対の支持部２６，６４が変位した場合に、該一対の支持部６４，６４間の略中央部を中心として振れるように構成された振り子部材６６と、この振り子部材６６の端部と前記矩形フレーム６１との間に設けられた制振部材６７とを備えている。   The vibration control mechanism is supported by the pair of support portions 64 and 64, and when the pair of support portions 26 and 64 are displaced, the vibration control mechanism swings around a substantially central portion between the pair of support portions 64 and 64. A pendulum member 66 configured as described above, and a damping member 67 provided between the end of the pendulum member 66 and the rectangular frame 61 are provided.

振り子部材６６は鉄やアルミニウム等の金属製のものであり、上下に長尺な板状に形成され、長手方向を上下に向けて配置されている。振り子部材６６の中央部の左半分は、一方の支持部６４に軸６８によって回動自在に支持されており、右半分は他方の支持部６４に軸６８によって回動自在に支持されている。
このように、一対の支持部６４，６４の先端部によって振り子部材６６の長手方向中央部が軸６８，６８によって回動自在に支持されているので、この振り子部材６６は、地震等の振動によって矩形フレーム６１が変形して一対の支持部６４，６４が変位した場合に、該一対の支持部６４，６４間の略中央部を中心として左右に振れるように構成されている。
なお、前記軸６８，６８のうち一方の軸６８は左右にも若干スライドできるようになっている。 The pendulum member 66 is made of a metal such as iron or aluminum, is formed in a plate shape that is long in the vertical direction, and is arranged with its longitudinal direction facing up and down. The left half of the central portion of the pendulum member 66 is rotatably supported by one support portion 64 by a shaft 68, and the right half is rotatably supported by the other support portion 64 by a shaft 68.
As described above, since the central portion in the longitudinal direction of the pendulum member 66 is rotatably supported by the shafts 68 and 68 by the tip portions of the pair of support portions 64 and 64, the pendulum member 66 is caused by vibration such as an earthquake. When the rectangular frame 61 is deformed and the pair of support portions 64 and 64 are displaced, the rectangular frame 61 is configured to swing left and right about a substantially central portion between the pair of support portions 64 and 64.
Of the shafts 68, 68, one shaft 68 can slide slightly to the left and right.

前記制振ボックス６９の内側面には、例えば高減衰ゴムによって形成された粘弾性体からなる制振部材６７が取り付けられており、この制振部材６７には、プレート（図示略）が固着されている。そして、このプレートが前記振り子部材６６の端部にボルトによって連結されている。したがって、制振部材６７は、プレートを介して振り子部材６６の端部に取り付けられ、また、制振ボックス６９を介して横フレーム６３に取り付けられている。   A damping member 67 made of a viscoelastic body formed of, for example, high damping rubber is attached to the inner side surface of the damping box 69, and a plate (not shown) is fixed to the damping member 67. ing. The plate is connected to the end of the pendulum member 66 by a bolt. Therefore, the damping member 67 is attached to the end portion of the pendulum member 66 via the plate, and is attached to the horizontal frame 63 via the damping box 69.

前記制振装置６では、地震等の振動によって建物躯体に変形が生じると、一対の構造材７，７から矩形フレーム６１を介して、一対の支持部６４，６４が変位する。一対の支持部６４，６４が変位することによって、振り子部材６６が一対の支持部６４，６４間の略中央部を中心として振り子のように振れ、この振り子部材６６の端部は振れが増幅され、これによって、前記一対の支持部６４，６４の変位が増幅される。
したがって、振り子部材６６の端部と矩形フレーム６１との間に設けられている制振部材６７の変形を増幅できるので、建物躯体の小さな変形から制振機能を有効に働かせることができるとともに、この制振部材によって振り子部材６６の振動を制振し、これによって、矩形フレーム６１の振動を制振するようになっている。そして、この矩形フレーム６１を制振することによって、構造材７，７を介して建物の振動を制振するようになっている。 In the vibration damping device 6, when the building housing is deformed by vibration such as an earthquake, the pair of support portions 64 and 64 are displaced from the pair of structural members 7 and 7 through the rectangular frame 61. By the displacement of the pair of support portions 64, 64, the pendulum member 66 swings like a pendulum around the substantially central portion between the pair of support portions 64, 64, and the end of the pendulum member 66 is amplified in swing. As a result, the displacement of the pair of support portions 64, 64 is amplified.
Therefore, since the deformation of the vibration damping member 67 provided between the end of the pendulum member 66 and the rectangular frame 61 can be amplified, the vibration damping function can be used effectively from a small deformation of the building frame. The vibration of the pendulum member 66 is damped by the vibration damping member, and thereby the vibration of the rectangular frame 61 is damped. Then, by suppressing the rectangular frame 61, the vibration of the building is suppressed via the structural members 7 and 7.

本実施の形態によれば、上面に土台２が設置された基礎４に接合される基礎接合金物１６と、土台上に設置される構造材７の下端部に取り付けられる取付金物１７とを備え、基礎接合金物１６は、土台２の上面に設置される設置板１９を備え、取付金物１７は、設置板１９に接合固定される接合板２２を備えているので、基礎接合金物１６を基礎に接合するとともに、設置板１９を土台２の上面に設置し、構造材７の下端部に取付金物１７を取り付け、この取付金物１７の接合板２２を前記設置板１９に接合固定することによって、従来のように、土台上面から基礎の下端部まで延びる深い孔や、基礎の側面に切欠きを形成することなく、基礎連結金物１５を介して構造材７を基礎４に容易かつ確実連結できる。   According to the present embodiment, it comprises a base joint hardware 16 joined to the foundation 4 on which the base 2 is installed on the upper surface, and an attachment hardware 17 attached to the lower end of the structural material 7 installed on the base, The base joint hardware 16 includes an installation plate 19 installed on the upper surface of the base 2, and the mounting hardware 17 includes a joint plate 22 joined and fixed to the installation plate 19, so that the base joint hardware 16 is joined to the foundation. In addition, the installation plate 19 is installed on the upper surface of the base 2, the attachment metal 17 is attached to the lower end portion of the structural material 7, and the joining plate 22 of the attachment hardware 17 is joined and fixed to the installation plate 19. As described above, the structural material 7 can be easily and reliably connected to the foundation 4 via the foundation connection hardware 15 without forming a deep hole extending from the upper surface of the foundation to the lower end of the foundation or a notch on the side surface of the foundation.

また、取付金物１７の支持板２４に構造材７の下端面を当接して該構造材７を支持するとともに、この構造材７の下端面に形成された挿入孔（被挿入部）７ａに挿入部２５を挿入し、この挿入部２５と挿入孔７ａの内面との間に接着剤Ｓを充填することによって、構造材７の下端部に取付金物１７を容易かつ確実に取り付けることができる。
さらに、取付金物１７が構造材７の下端部に工場等において予め取り付けられているので、現場では、取付金物７の接合板２２を基礎に接合された基礎接合金物１６の設置板１９に接合固定することによって、基礎連結金物１５を介して構造材７を基礎４に容易かつ確実連結できる。 In addition, the lower end surface of the structural member 7 is brought into contact with the support plate 24 of the mounting hardware 17 to support the structural member 7 and inserted into an insertion hole (inserted portion) 7 a formed in the lower end surface of the structural member 7. By inserting the portion 25 and filling the adhesive S between the insertion portion 25 and the inner surface of the insertion hole 7a, the mounting hardware 17 can be easily and reliably attached to the lower end portion of the structural member 7.
Further, since the mounting hardware 17 is attached in advance to the lower end of the structural material 7 at a factory or the like, it is fixed on the installation plate 19 of the base bonding hardware 16 bonded on the basis of the bonding plate 22 of the mounting hardware 7 at the site. By doing so, the structural material 7 can be easily and reliably coupled to the foundation 4 via the foundation coupling hardware 15.

また、制振壁体５の上端部は鋼製ガセット１０によって梁１に連結され、制振壁体５の下端部は基礎連結金物１５によって基礎４に連結されているので、制振壁体５の上端部を梁１に強固に連結でき、制振壁体５の下端部を基礎４に強固に連結できる。したがって、地震等の際に建物に生じる振動を制振壁体５の内部に設けられた制振装置６に作用させることができ、該制振装置６によって確実に建物の振動を制振できる。
さらに、制振壁体５が左右一対の構造材７，７、上壁部８、下壁部９を備え、これら一対の構造材７，７、上壁部８、下壁部９に矩形状をなす制振装置６が固定されているので、制振壁体５の内部に容易かつ確実に制振装置６を組み込むことができる。 Moreover, since the upper end part of the damping wall body 5 is connected with the beam 1 with the steel gusset 10, and the lower end part of the damping wall body 5 is connected with the foundation 4 with the foundation connection metal fitting 15, it is the damping wall body 5 Can be firmly connected to the beam 1, and the lower end of the damping wall 5 can be firmly connected to the foundation 4. Therefore, the vibration generated in the building in the event of an earthquake or the like can be applied to the vibration control device 6 provided inside the vibration control wall body 5, and the vibration of the building can be reliably controlled by the vibration control device 6.
Further, the damping wall 5 includes a pair of left and right structural members 7, 7, an upper wall portion 8, and a lower wall portion 9. The pair of structural members 7, 7, the upper wall portion 8, and the lower wall portion 9 are rectangular. Since the vibration damping device 6 is fixed, the vibration damping device 6 can be easily and reliably incorporated into the vibration damping wall 5.

また、上壁部８と一対の構造材７，７の上端部とが梁１に鋼製ガセット１０によって連結されるので、制振壁体５の上端部を確実かつ強固に梁１に連結できる。
加えて、一対の構造材７，７の下端部がそれぞれ基礎４に基礎連結金物１５，１５によって連結されているので、制振壁体５の下端部を確実かつ強固に基礎４に連結できるとともに、構造材７，７はその側面に制振装置６が固定され、上端部が梁１に連結され、下端部が基礎４に連結されているので、地震等の際に建物に生じる振動を制振装置５に有効に作用させることができる。 Moreover, since the upper wall part 8 and the upper end part of a pair of structural material 7 and 7 are connected with the beam 1 by the steel gusset 10, the upper end part of the damping wall body 5 can be connected with the beam 1 reliably and firmly. .
In addition, since the lower ends of the pair of structural members 7 and 7 are respectively connected to the foundation 4 by the foundation connecting hardware 15 and 15, the lower end of the damping wall 5 can be reliably and firmly connected to the foundation 4. The structural members 7 and 7 have a vibration damping device 6 fixed to their side surfaces, an upper end connected to the beam 1 and a lower end connected to the foundation 4, so that vibrations generated in the building in the event of an earthquake or the like are suppressed. The vibration device 5 can be effectively operated.
