である。2. Description of the Related Art Conventionally, as a damping device linked to earthquake resistance in the event of a large earthquake, a damper is provided between two buildings (structures) arranged side by side to attenuate vibrations of the two buildings in the direction of relative movement toward and away from each other. There is something. FIG. 4 (a) shows the two floors of two completely independent buildings 1 and 2 with a passage 2
1 and a damper is provided in this passage 21 portion. On the other hand, the one shown in FIG. 4 (b) looks like one large building from the outside, but in fact, the two separated buildings 1 and 2 are connected to each other by the roof garden 22 at the upper part,
The roof garden 22 is provided with a damper.

な減衰力を比較的小さな装置変位で得られる。A device having a damper between two buildings as described above has an advantage that a large damping force can be obtained as compared with other devices. That is, as another device, for example, a passive type device using an additional weight of about 1% of the weight of a building is known, and the damping force is the inertial force of the additional mass (product of mass and acceleration). It is obtained as a reaction force, and the weight of the additional mass that can be installed on the roof of the building is limited,
There is also a limit to the power of the attenuation. However, in the damping device provided between the two buildings or the like, since the damping force is a reaction force between the inertial force and the rigidity of both buildings, a large damping force can be obtained with a relatively small device displacement.

提案されている（特開平６−１７３４９８号公報）。[0004] In addition, if only the damper is connected as described above, the relationship between the weight ratio and the rigidity ratio of the building is uniquely determined, and it is not possible to adjust the optimum conditions for the vibration damping effect at the time of a large earthquake. As shown in the model of FIG. 3, the two independent buildings (mass m1, m2, spring constants k1, k2) can be connected by a damper 27, and a spring 26 is added in parallel with the damper 27, as shown in the model of FIG. It has been proposed to obtain a range in which an optimum design is possible by using the connecting spring 26 (Japanese Patent Laid-Open No. Hei 6-173498).

に有効に制振することができる。On the other hand, as shown in FIG. 2, for example, a vibration damping device that can attenuate vibrations in a laterally displaced movement direction X between two parallel buildings is considered. This damping device is provided with a fulcrum 24 of a lever 23 on one building 2.
And a force point 25 of the lever 23 is engaged with the other building 1 so as to absorb the displacement in the moving direction Y relative to each other, and a spring is provided between the point of action of the lever 23 and the building 2. Rigidity k
3 and a spring 26 and a damper 27 having a small allowable deformation are attached, and the lever ratio b / a is configured to be smaller than 1.
By setting the optimal spring and damper according to the vibration characteristics of the two buildings 1 and 2 to be connected, even in the case of a large amplitude such as a large earthquake, the vibration in the direction of the relative movement toward and away from the building is set to this. Vibration can be effectively suppressed without being affected by vibrations in the orthogonal direction.

The vibration of the component of the lateral displacement movement (X direction) relatively parallel to each other cannot be released,
Under the influence of the vibration in the X direction, there is a possibility that the two buildings may be connected to each other to damage the connection part such as the passage 21 where the damper or the spring is provided and the roof garden.

Although the oscillating vibration in the direction X can be effectively attenuated, it is difficult to effectively attenuate the oscillating vibration in the approaching / separating movement direction orthogonal to this.

The damper 13 and the spring 14, which are connected between both ends thereof, provide resistance to the expansion and contraction operation. At this time, the position of the ends 3b and 4a of the connecting beams 3 and 4 in the X direction changes due to the expansion and contraction operation of the first and second connecting beams 3 and 4, that is, the rotation about the connecting shaft 5.

If this is done, the rail 12 will move relatively sideways with respect to the bogie 10, and as a result, vibrations in the left and right directions of the building 2 will be released and cut off at the respective sliding bearings 7 and 9. , And the first and second connecting beams 3 and 4. For this reason, the first and second connecting beams 3,
The left and right vibrations of the building 2 are not transmitted to the two sets of the dampers 13 and the springs 14 connected between the bearings 6, 7, 8, and 9 at the respective ends of the building 4. Therefore, the positions of the two sets of dampers 13 and springs 14 are always constant without being affected by the swing in the X direction.
【００２１】かくして、２つの建物１，２の水平面内の

ある。In the embodiment described above, the mounting positions of the dampers 13 and the springs 14 provided between the connecting beams 3 and 4 are between the carriages 10 and 10 of the slide bearings 7 and 8 and the fixed bearing 6 and the slide bearing 9. Between the trolleys 10 are selected. The reason is that when the damper 13 and the spring 14 are directly mounted between the connecting beams 3 and 4, the force of the damper 13 and the spring 14 is applied to the fixed bearing 6 of each of the pivots 3a, 3b, 4a and 4b and the shaft of the bogie 10. On the other hand, when the damper 13 and the spring 14 are provided between the above-mentioned bogies or the like, the bogie 10 is supported by the rail 12 having a large area, so that the pivots 3a, 3b, 4
This is because the adverse effects of the shafts a and 4b on the shaft rotation can be sufficiently avoided.

It suffices if the relationship that the mounting position of 4 does not change in the X direction is sufficient. Therefore, it can be provided at any position between the connecting beams 3 and 4.

い。Further, a damper 13 is provided between the connecting beams 3 and 4.
When attaching the spring 14, the connecting beams 3, 4 are further extended from the bearings 7, 8 or 6, 9, and the damper 13 and the spring 14 are attached between the extending portions, that is, the damper 13 and the spring 14 are connected from the connecting shaft 5. The arm length from the connecting shaft 5 to the mounting position of the bearing 14, 6, 7, 8,
By changing the lever ratio to be longer than the arm length up to 9, it is possible to have an effect of amplifying the amplitude at the damping force action point. In order to provide an amplifying effect in this way, the damper 13 and the spring 14 do not necessarily need to be arranged between the connecting beams 3 and 4, and the fixed bearing 6

で回動可能に連結された２つの連結ビームを渡し、それ
ぞれのビーム端部を対応する建物に取り付け、その際、
その１つのビーム端部だけは固定軸受けを介して取り付
け、他の３つのビーム端部は、２つの建物相互の相対的
な近接離間移動方向の振動と直交する方向にスライドし
得るように滑り軸受けを介して取り付け、前記２つの連
結ビーム間あるいはビーム端部の軸受け間にダンパー及
びバネを設けたことを特徴とする制振装置。1. Between two buildings, an intermediate intersection passes two connecting beams pivotally connected in a horizontal plane, and each beam end is attached to a corresponding building,
Only one of the beam ends is mounted via a fixed bearing, and the other three beam ends are sliding bearings so that they can slide in a direction orthogonal to the vibration of the relative movement of the two buildings relative to each other. A damper and a spring are provided between the two connecting beams or between bearings at the beam ends.
