  • Patent number: 7758948
    Abstract: A laminate support includes a layered elastic body structured by rigid plates, which have rigidity, and elastic plates, which have elasticity, being layered alternately in a predetermined layering direction, and a hollow portion is formed in the layered elastic body in the layering direction. A plastic fluid material structured by an elastic perfect plastic body (a non-hardening elastoplastic body) is placed-in the elastic body hollow portion of the layered elastic body. Further, a plurality of particle-shaped hard fillers, which are structured of a hard material which is considered to be a rigid body with respect to the plastic fluid material, are filled-in the plastic fluid material so as to be a predetermined volume fill rate. A laminate support, which can be disposed of or the like at a low cost and which can exhibit a large damping force, can be obtained.

  • Patent number: 5353559
    Abstract: An anti-earthquake bearing apparatus for bearing the weight of a structure and reducing the vibration energy propagating to the structure by using bearing bodies disposed between the structure and a foundation or another structure has spherical bag-like bearing bodies serving as said bearing bodies formed by sealing a fluid, rubber-like solid or gas into bags constituted by a rubber-sheet material reinforced with fiber. Each bag-like bearing body is provided with charging/discharging ports. Recesses for preventing positional shift of said bag-like bearing bodies are formed on the bottom surface of the structure and on the upper surface of the foundation.
