Description of the Related Art In order to control a high-rise building, it is necessary to control bending deformation, and in order to efficiently control this bending deformation, a method of applying a horizontal force to the building top can be considered. That is, in this case, a control moment force obtained by multiplying the applied horizontal force by the building height can be generated, so that a large control force can be efficiently obtained. TMD and AMD are known as damping methods of this kind, but in these devices, an excessive additional mass is required in order to keep the amplitude of the additional mass below the allowable stroke of the device, and it is extremely difficult to realize it.

題が生じてしまう。However, in the above-described conventional vibration damping device utilizing the rotary inertia force, in which the pinion having the additional mass body attached is rotated by the rack shaft, the rotation shaft of the pinion is the rack shaft. And the additional mass will rotate in a plane parallel to the rack axis. Therefore, if the radius of gyration of the additional mass body such as the flywheel or weight is increased in order to increase the rotational inertial force while suppressing the increase in the weight of the vibration control device, a large space is secured for the installation part such as the rooftop. There was a problem that we had to do. Further, in order to increase the rotational inertial force, it is sufficient to amplify the amount of movement of the rack axis due to the relative displacement of both buildings and convert it to the amount of rotation of the pinion and transmit it. The amplification factor is the unit length of the rack axis. Although it is determined by the relationship between the number of teeth per contact and the number of teeth of the pinion, the size cannot be reduced so much because the additional mass is attached to and supported by the pinion, so there is a limit to obtaining a large amplification factor. there were. Therefore, it is conceivable to provide a plurality of pinions with additional mass bodies engaged with the rack shafts, but this causes a problem that the space occupied by the installation portion further increases.

転する。In the coupled vibration damping device of the present embodiment having the above-mentioned configuration, when vibration is generated by an earthquake or wind and relative displacement is generated between the first and second buildings 10 and 12 standing in parallel,
The bearing member 22 supporting the nut member 16 of the ball screw mechanism 14 and the sleeve 3 at the base end of the screw shaft member 18.
4 rotates in the horizontal direction, following the relative displacement direction of both buildings 10, 12. Then, the spindle 26 on the first building 10 side that rotatably supports the bearing member 22, and the screw shaft member 18
The relative displacement (that is, the change in distance between the two support shafts 26, 36) that occurs between the support shaft 36 on the second building 12 side that rotatably supports the nut member 16 and the screw shaft member 18 of the ball screw mechanism 14. Linearly acting on the threaded portion of the nut member 16 along its axial direction, and as a result, the nut member 16 is rotated at the amplification amount and the rotation speed corresponding to the thread pitch of the threaded portion. The flywheel 28, the weight 32, and the like of the additional mass body 20 that are integrally provided in the same also rotate together.

制振機能を確保することができる。Therefore, the rotary mass body composed of the nut member 16, the flywheel 28, the weight mounting bolt 30 and the weight 32 generates a rotary inertia force with the relative displacement of the first and second buildings 10 and 12. However, the rotational inertial force can be used as a reaction force to suppress the first and second buildings 10 and 12. At this time, since the screw shaft member 18 mainly receives the relative displacement load as a compressive force in the axial direction having a large strength, the screw shaft member 18 can sufficiently cope with a large relative displacement amount between the two buildings 10 and 12. Therefore, even if an excessive relative displacement occurs between the buildings 10 and 12 due to a large earthquake or the like, the vibration damping function can be sufficiently ensured.

きる。Further, as is well known, the rotational inertia force causes the rotational speed ω even if the total mass of the rotary mass body including the nut member 16 and the flywheel 28 of the additional mass body 20 and the weight 32 is constant. And the mass of the weight 32 of the additional mass and its rotation radius r, the magnitude of the rotational inertial force is proportional to the square of the rotation radius r, and the rotation speed ω
However, the reciprocating linear motion of the screw shaft member 18 due to the relative displacement of the two buildings 10 and 12 is proportional to the nut member 16
By appropriately setting the screw pitch (amplification factor) of the ball screw mechanism 14 for converting into the reciprocating swing rotary motion of, and the turning radius r and the mass of the weight 32 which is the additional mass body,
A desired rotational inertia force (that is, damping force) can be easily obtained.

The side walls 10a of the building 10 are laterally projected and spaced apart, and can be rotated in the vertical plane in the space between the buildings 10 and 12 about the axis of the screw shaft member 18, so that the two buildings 10 that are in parallel are Even if 12 are close to each other and the space between them is narrow, the additional mass body 20 including the flywheel 28 and the weight 32 can be easily installed in the space.
The rotation radius r of the weight 32 can also be increased as much as possible to increase the rotational inertial force while suppressing the increase in weight. In addition, the additional mass body 20 does not occupy a large space on the rooftop, and thus the installability is excellent.
