[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibration damper device. Specifically, when a layer displacement force due to wind pressure or an earthquake acts on a building or other structure, the displacement (vibration) energy is absorbed and the shaking motion or vibration of the structure is dampened. The present invention relates to a vibration damper device that is used by being incorporated as a brace, a cane or the like in the structural frame.

[0002]

2. Description of the Related Art A vibration damper device of this type generally has at least three rigid plates such as steel plates arranged in parallel with each other at a distance from each other, and is joined to one of opposing parts of a frame structure. A possible first joining member and a sliding plate such as at least two steel plates arranged in parallel with the rigid plates at an intermediate position between adjacent at least three rigid plates in the first joining member, A second joining member that can be joined to the other of the facing portions of the frame structure, and a viscoelastic body interposed in layers between the facing surfaces of the rigid plate of the first joining member and the sliding plate of the second joining member. When the first joint member and the second joint member are displaced relative to each other within a two-dimensional plane (plane) due to an interlayer displacement force acting on the frame structure due to an earthquake etc. Layered energy absorption By absorbing in the shear deformation, and is configured to exert a damping performance for damping oscillatory movement or vibration of the building.

By the way, in the vibration damper device which exerts the vibration damping performance by utilizing the shear deformation characteristic of the energy absorbing material as described above, the desired vibration damping performance can be achieved without lowering the energy absorbing performance originally possessed by the energy absorbing material. In order to make sure that the energy absorption material is exposed to excessive compression and bending,
Preventing deformation force other than shearing such as twisting from being applied, that is, buckling deformation of the first and second joining members that bear a great amount of tensile force and compression force in actual use as a brace or a cane. It is necessary to have sufficient buckling strength so as not to bend or deform.

As a vibration damper device having such a requirement, that is, a high buckling strength, a vibration damper device 30 having a structure as shown in FIG. 9 has been conventionally proposed. The conventional vibration damping damper device 30 includes left and right side plates 31 and 31 and the left and right side plates 3 which are spaced apart from each other and arranged parallel to each other along the damper longitudinal direction.
The intermediate plate 32 arranged at an intermediate position between the terminals 1 and 31 is made of a flat rigid plate such as a steel plate, and the left and right side plates 31 and 31 are bolted to the channel steel 33 at both ends in the plate width direction. -Fixing and coupling with fasteners 34, 34 such as nuts, and tap holes for fastening bolts are formed on both end edges of the intermediate plate 32 in the plate width direction.
The channel steel 33 and the intermediate plate 32 are fixedly connected to each other by screwing the bolt 35 into the first joint member 36, and the left and right side plates 31, 3 of the first joint member 36 are formed.
1 and the intermediate plate 32, the sliding plates 37, 37 arranged in parallel with the plates 31, 31, 32 are made of flat rigid plates such as steel plates, and the sliding plates 37, 37 are The second joining member 3 is fixed by bundling and fixing the end portions in the plate longitudinal direction.
The left and right side plates 3 of the first joining member 36.
1 and 31, the intermediate plate 32, and the respective sliding plates 37, 37 of the second joining member 38 are formed by interposing viscoelastic bodies 39 ...

[0005]

In the conventional vibration damping damper device having the above-mentioned structure, since a hollow rectangular parallelepiped is formed by the channel steel 33 and the left and right side plates 31, 31, a very high buckling strength is secured. Even if a large tensile force or compressive force is applied in the actual use state, the left and right side plates 31, 31, which are flat rigid plates such as steel plates, the intermediate plate 32, and further the sliding plate 37. , 37 will not be buckled or bent, so that the viscoelastic body 39 ... Maintains the desired vibration damping performance stably for a long period of time without lowering the original energy absorption performance. It has the advantage of being able to. On the other hand, when the intermediate plate 32 on the first joining member 36 side is fixedly connected to the channel steel 33, the intermediate plate 3
It is necessary to machine small-diameter bolt fastening tap holes that are restricted to the plate thickness range on both edges in the plate width direction of 2 and to install bolts 35 from the narrow opening side of the channel steel 33 into the small-diameter tap holes. Since it is necessary to screw in the hole, high precision is required for processing the hole itself, and the assembly of the first joining member 36 becomes very difficult.

Further, the sliding plate 37 on the second joint member 38 side,
As for 37, since it is necessary to bundle and fix them at the ends in the plate longitudinal direction, the sliding plates 37, 37 become cantilever, and when they are subjected to a large tensile force or compressive force, The intermediate portion is likely to buckle or bend and deform, and as a result, the energy absorption performance of the viscoelastic body 39 ... May deteriorate and the desired vibration damping performance may not be maintained. Further, since both the left and right side plates 31, 31 and the intermediate plate 32 on the side of the first joining member 36 are fixedly connected to the channel steel 33, only the tolerance of the tap hole is displaced between the both 31, 31, 32. However, each plate 31,
Since the relative position between 31, 32 and the sliding plate 37, 37 on the side of the second joining member 38, that is, the member that serves as a guide for determining the thickness dimension of the viscoelastic body 39 ... Is not present, the entire assembly can be accurately assembled. This is not possible, and there is a high possibility that symmetry in the plate width direction will shift, and there is a problem that the finished quality of the product (damper device) tends to vary.

The present invention has been made in view of the above-mentioned circumstances, and it is easy and high in that the respective plates are maintained in the relative positional relationship as designed while ensuring a high buckling strength. It is an object of the present invention to provide a vibration damper device that can be assembled with high precision, can achieve a constant finish quality, and can stably maintain desired vibration damping performance.
