免震構造
Document Type and Number:
Japanese Patent JP6681667
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a base-isolation structure capable of continuous elastic deformation to cope with small-, medium- and large-scale earthquakes, without coming in contact with laminated rubber that supports a superstructure.SOLUTION: A base-isolation structure is installed between a substructure 12 and a superstructure 14, and includes: laminated rubber 10 supporting the superstructure 14; elastic deformation means 16, 17 installed between the substructure 12 and the superstructure 14 aside from the laminated rubber 10 and in parallel with the laminated rubber 10, the elastic deformation means providing rigidity to the superstructure 14 by coming in contact with each other when a relative displacement amount between the substructure 12 and the superstructure 14 reaches a prescribed value, and not coming in contact with each other until the prescribed value is reached; and a viscous damper 18 installed between the substructure 12 and the superstructure 14 in parallel with the laminated rubber 10 and the elastic deformation means 16, 17, for absorbing vibration energy.SELECTED DRAWING: Figure 1
