Definitions
- the present invention has a mechanism for fixing the vertical angle of the upper and lower rollers and a function for controlling and suppressing the damping force in the roller support mechanism perpendicular to the upper and lower rollers.
- the present invention relates to a technology in which a damper-type damping mechanism is provided to the seismic isolation device.
- the existing equipment uses materials such as rubber, lead, synthetic oil, synthetic resin, steel, etc. and requires advanced technology. Also, it contains deteriorated materials, and the mechanism has an internal structure and the accuracy of parts is also precise. In addition to the need, specific manufacturers, specific materials are required, advanced processing techniques and special machine tools are often required, and the amount of production is small, so it is expensive and not popular. In addition to the need for replacement of inspection parts from a specialized point of view over a long period of use, it is difficult to inspect the internal structure, which is not preferable for maintenance.
- a damping mechanism is provided.
- the existing damping mechanism generally has a damping capacity based on the energy absorption amount of the target maximum earthquake area, so for a small seismic force, the damping capacity based on a large earthquake is excessive, Since the horizontal force buffering function of the support mechanism, which is a relative function to the damping function, is obstructed, the structure will be damaged due to the excessive damping capacity even though a seismic isolation device is installed in the case of a small earthquake. As a result, a solution is desired.

Cover the sides face-to-face, fold the open end at a right angle to the outside, drill four holes for connecting bolts in the bent surface, and firmly connect the contact surfaces of the restraining materials (9) and (10).
- the operating environment of the damping mechanism is adjusted by an orthogonal angle fixing mechanism that can be coupled by (11) and prevent twisting of the rollers (3) and (4).
- the structure of the damping mechanism in the seismic isolation device provided with the above-described fixing mechanism is obtained by winding a linear steel material (14), which is a plastic material, around an outer cylindrical material (13) to form a linear steel material (14 ) And the outer cylindrical member (13) are relatively displaced so that a damping force can be obtained by the energy absorbing function accompanying the deformation of the linear steel member (14).

Absorption was suppressed. "Claims 3.4"
- outer cylindrical material (14) is attached to the outer cylindrical material (14) by the right-handed and left-handed number of the same or the cross-sectional area having the same axial resistance in the left-handed and right-handed directions. Except for the couple acting on 13), the outer cylindrical member was prevented from being twisted to stabilize the operating environment of the damping mechanism. "Claim 6"
