The fastening bolts 35, 35 are inserted into both end portions of the outer peripheral plate portion 12a. Further, the fastening bolts 35, 35 are vertically passed through the holes 26a, 26a of the lower structural member 26, and then the recesses 26b, 26b. The lower end portions of the fastening bolts 35, 35 are screwed into the nuts 34, 34 housed in, and then tightened.
In addition, a plurality of wood screws 28 are inserted into the outer peripheral plate portion 12a between the fastening bolts 35 and 35 at both left and right end portions, and then screwed into the upper end surface of the lower structural member 26.

次に、図８に示すように、制振装置１の上の横フレーム１２と横架材２との間に、上構造材２５をはめ込んで、上構造材２５の下端面に横フレーム１２の外周板部１２ａを当接するとともに、横架材２の下面に上構造材２５の上端面を当接する。

After being inserted into the outer peripheral plate portion 12a, it is screwed into the lower end surface of the upper structural member 25.

最後に、図１に示すように、ガセットプレート３０，３０を、上構造材２５と横架材２の表裏両面に当接し、それぞれ接着剤によって固定するとともに、釘をガセットプレート３０，３０の表面から打ち込むことによって上構造材２５と横架材２に固定する。なお、上構造材２５から横架材２に向けて斜めに釘打ちを行ってもよい。 Finally, as shown in FIG. 1, the gusset plates 30, 30 are brought into contact with both the upper and lower surfaces of the upper structural member 25 and the horizontal member 2 , and fixed with adhesives, and the nails are attached to the surfaces of the gusset plates 30, 30. It is fixed to the upper structural member 25 and the horizontal member 2 by driving in. Note that nailing may be performed diagonally from the upper structural member 25 toward the horizontal member 2.

制振装置１が取り付けられた建物の躯体では、図２に示すように、建物に地震等の横揺れ振動によって変形が生じると、上下に離間して配置された横架材２と土台３とが互いに水平方向（左右方向）逆方向に変位し、これに伴って、上下の構造材２５，２６が互いに水平方向逆方向に変位する。これによって、制振装置１の矩形フレーム７の上下の横フレーム１２，１２が左右にずれるようにして変位するとともに、縦フレーム１１，１１が横方向に傾斜することによって矩形フレーム７が略平行四辺形状に変形する。
矩形フレーム７が略平行四辺形状に変形すると、一対の支持部８，８が斜め上下に互いに離間するようにして変位する。
一対の支持部８，８が変位することによって、振り子部材１５が一対の支持部８，８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１５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８，８の変位が増幅される。
そして、振り子部材１５の端部と制振ボックス１６のプレート２２とが連結されており、この連結されたプレート２２は粘弾性体２１，２１間に挿入されかつ該一対の粘弾性体２１，２１に固着されているので、この粘弾性体２１，２１の変形を増幅できる。したがって、建物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。
また、粘弾性体２１，２１の変形速度も建物の変形速度より増幅することができるため、エネルギー吸収性能が変形速度に比例する粘弾性材料から形成された粘弾性体を用いる場合には、より効率的にエネルギーを吸収でき、大きな減衰力を発揮できる。 As shown in FIG. 2, in the building frame to which the vibration damping device 1 is attached, when the building is deformed by rolling vibration such as an earthquake, the horizontal member 2 and the base 3 that are spaced apart from each other are arranged. Are displaced in the horizontal direction (left and right direction) opposite to each other, and accordingly, the upper and lower structural members 25 and 26 are displaced in the horizontal direction opposite to each other. Thus, with the upper and lower lateral frames 12 and 12 of the rectangular frame 7 of the vibration damping device 1 is displaced so as to deviate to the left or right rectangular Katachifu frame 7 by the vertical frame 11, 11 is inclined in the lateral direction substantially Deforms into a parallelogram shape.
When the rectangular frame 7 is deformed into a substantially parallelogram shape, the pair of support portions 8 and 8 are displaced so as to be spaced apart from each other vertically.
When the pair of support portions 8 and 8 are displaced, the pendulum member 15 swings like a pendulum around the substantially central portion between the pair of support portions 8 and 8, and the end portion of the pendulum member 15 is amplified. As a result, the displacement of the pair of support portions 8, 8 is amplified.
Then, the end portion of the pendulum member 15 and the plate 22 of the damping box 16 and is coupled, plate 22 this is connected is inserted between the viscoelastic member 21 and the pair of the viscoelastic body 21 Therefore, the deformation of the viscoelastic bodies 21 and 21 can be amplified. Therefore, the vibration control function can be used effectively from a small deformation of the building.
In addition, since the deformation speed of the viscoelastic bodies 21 and 21 can be amplified from the deformation speed of the building, when using a viscoelastic body formed of a viscoelastic material whose energy absorption performance is proportional to the deformation speed, It can absorb energy efficiently and exert a great damping force.

本実施の形態によれば、以下のような効果を奏する。
上下に離間して配置された横架材２と土台３との間に制振装置１が配置され、制振装置１の上の横フレーム１２が、矩形板状の上構造材２５を介して、横架材２に取り付けられており、制振装置１の下の横フレーム１２が、矩形板状の下構造材２６を介して、前記土台３に取り付けられているので、柱がない部位でも、上下に離間して配置された横架材２と土台３との間に制振装置１を容易に取り付けることができる。
また、制振装置１の上の横フレーム１２をボルト２７によって上構造材２５に強固に固定でき、この上構造材２５をガセットプレート３０によって横架材２に強固に固定できるので、制振装置１を上構造材２５を介して横架材２に強固に取り付けることができる。 According to the present embodiment, the following effects can be obtained.
The vibration damping device 1 is disposed between the horizontal member 2 and the base 3 that are spaced apart from each other in the vertical direction, and the horizontal frame 12 on the vibration damping device 1 is interposed via the upper structural member 25 having a rectangular plate shape. Since the horizontal frame 12 under the vibration damping device 1 is attached to the base 3 via the rectangular plate-like lower structural member 26, the horizontal frame 12 under the vibration control device 1 is attached to the base 3, The vibration damping device 1 can be easily attached between the horizontal member 2 and the base 3 that are spaced apart from each other in the vertical direction.
Further, the horizontal frame 12 on the vibration damping device 1 can be firmly fixed to the upper structural member 25 with the bolts 27, and the upper structural member 25 can be firmly fixed to the horizontal member 2 with the gusset plate 30. 1 can be firmly attached to the horizontal member 2 via the upper structural member 25.

さらに、制振装置１の下の横フレーム１２が、基礎３１に連結手段３２を介して連結されているので、地震の際に、地盤の振動が基礎３１から連結手段３２を介して制振装置１に確実に伝達されるので、制振装置１の制振機能を確実に働かせることができる。
加えて、基礎３１に基礎連結金具３３を連結したうえで、土台３に下構造材２６を設置し、この下構造材２６に締結ボルト３５を貫通して、基礎連結金具３３の上面部に固定されたナット３４に締結ボルト３５を螺合することによって、制振装置１の下の横フレーム１２を基礎３１に容易かつ確実に連結できる。
また、基礎連結金具３３の両側面部３３ｂ，３３ｂをそれぞれ土台３の両側面および基礎３１の両側面にそれぞれ当接し、上面部３３ａを土台３の上面に当接することによって、基礎連結金具３３を基礎３１および土台３にその厚さ方向および下方向にずれることなく設置でき、そのうえで、基礎３１にその厚さ方向に貫通されたボルト３６によって側面部３３ｂ，３３ｂを固定することにより、基礎連結金具３３を基礎３１に上方向にずれることなく設置できる。 Further, since the horizontal frame 12 under the vibration damping device 1 is connected to the foundation 31 via the connecting means 32, the vibration of the ground is transmitted from the foundation 31 via the connecting means 32 in the event of an earthquake. Therefore, the vibration damping function of the vibration damping device 1 can be operated reliably.
In addition, after connecting the foundation connecting bracket 33 to the foundation 31, the lower structural member 26 is installed on the base 3, and fastening bolts 35 are passed through the lower structural member 26 and fixed to the upper surface portion of the foundation connecting bracket 33. By screwing the fastening bolts 35 into the nuts 34, the lower frame 12 under the vibration damping device 1 can be easily and reliably connected to the foundation 31.
Also, basic both side surface portions 33b of the foundation connecting fitting 33, 33b each in contact on both sides of both side surfaces and foundation 31 of the base 3 equivalent, by abutting the upper surface portion 33a on the upper surface of the base 3, a basic connecting fitting 33 31 and can be installed without the foundation 3 being displaced in the thickness direction and the downward direction, Sonouede, thus the side surface portion 33b on the bolt 36 passing through in the thickness direction thereof to the base 31, Ri by the fixing the 33b, basic The connecting fitting 33 can be installed on the foundation 31 without shifting upward.
