[Problems to be solved by the invention]
There has already been proposed a technique for embedding a vibration control device in a wall of a building or the like so that the wall has a vibration suppression structure, and thus the entire building has a vibration suppression structure.
[0003]
As one of this type of vibration control device, there is known a device in which a viscous body is arranged in a container, and a movable plate is immersed in the viscous body in the container and is arranged to be movable with respect to the container. In the vibration damping device, in the vibration of the movable plate relative to the container due to an earthquake or the like, viscous shear is generated in the viscous body between the container and the movable plate, and the vibration damping effect is obtained by the viscous shear resistance in this viscous shear. .
[0004]
By the way, the vibration control device is usually arranged in the wall with the movable plate attached to the upper beam on the ceiling side and the container attached to the lower beam on the floor side. If the attachment mechanism attached to the wall occupies the entire interior of the wall, when it is desired to install a window, a door, or the like on the wall, the vibration control device and the attachment mechanism may become an obstacle, which may be extremely difficult.

DETAILED DESCRIPTION OF THE INVENTION
Next, the present invention and its embodiments will be described in more detail based on preferred examples shown in the drawings. The present invention is not limited to these examples.
[0018]
1 to 3, the damping wall structure 1 of this example includes two wall spaces 23 defined by two columns 21 and 22 and an upper beam 20 and a lower beam 19 that bridge the columns 21 and 22. In order to divide into spaces 24 and 27, the intermediate beam 17 as a cross member provided with a sufficient distance from both beams 19 and 20 and a lower space 27 defined by the intermediate beam 17 are arranged. The vibration damping device 2 is provided.

In the damping wall structure 1 described above, when the intermediate beam 17 side vibrates in the A direction relative to the lower beam 19 due to an earthquake or the like, the relative vibration in the A direction is transmitted to the movable plate body 10 via the steel member 12. As a result, in the relative vibration in the A direction between the movable plate 4 and the container 3, the high-viscosity body 5 is viscous sheared, thereby generating a viscous shear resistance against the relative vibration in the A direction. Damped and exhibits damping effect.
