摘要： A seismic isolation apparatus is structured such that a pair of seismic isolation mechanisms are formed each having a pair of upper and lower clamping members formed in the shape of a rectangular frame, wherein upper and lower roller guide surfaces, in each of which a longitudinal central portion is formed as a concavely arcuate curved surface and portions respectively extending therefrom are formed as convexly arcuate curved surfaces, are formed on the four sides of the upper and lower clamping members, and wherein rollers each having a circular cross section are respectively interposed between the upper and lower roller guide surfaces. The pair of seismic isolation mechanisms are installed by being superposed on top of each other such that the rolling directions of the rollers in the two seismic isolation mechanisms are perpendicular to each other. During the occurrence of an earthquake, the rollers are adapted to roll in contact with the upper and lower roller guide surfaces so as to absorb and dampen seismic waves in the longitudinal and transverse directions of the apparatus.

摘要： PROBLEM TO BE SOLVED: To provide a complex base-isolating mechanism which achieves a state of equilibrium with respect to bearing a load of a structure by an elastic base isolator and a horizontal movement support device, and establishes desired base-isolating performance thereof, to thereby reduce costs of the base-isolating mechanism and prevent degradation of the base-isolating performance. SOLUTION: The complex base-isolating mechanism is comprised of the elastic base isolator 1 and the horizontal movement support device 2 equipped with an elastic material 10, which are interposed between a lower structure 4 and an upper structure 3. The elastic base isolator 1 and the horizontal movement support device 2 bear vertical rigidity in an equilibrium state, to thereby mutually share and bear the load of the structure. Therefore, the load of the structure borne by the horizontal movement support device in the event of an earthquake is decreased, to thereby establish the desired base-isolating performance and prevent degradation of the same.

摘要： PROBLEM TO BE SOLVED: To prevent the floating in vertical vibration by rotatably mounting, on a roller bearing, the center part of an engagement member having rolling bodies on the upper and lower end parts, and providing guides for slidingly guiding the rolling bodies of the engagement member on the end surfaces of an upper support plate and a lower support plate. SOLUTION: The center part of a bar-like engagement member 6 is rotatably fixed to the end surface of a roller bearing 3, and rolling bodies 8, 9 are rotatably supported on the upper and lower end parts of the engagement member 6. Further, upper and lower guide grooves 10, 11 for horizontally guiding the rolling bodies 8, 9 supported on the upper and lower ends of the engagement member 6 in the engaged state with sliding according to the rolling of the roller bearing 3 are provided on the end surfaces of the upper and lower support plates 1, 2. Since the engagement member 6 sets the distance between the upper and lower guide grooves 10, 11 to the minimum according to this structure, the upper and lower support plates 1, 2 never vertically separate to each other. Accordingly, even if a vertical vibration is worked, the floating can be prevented.
