DEVICE FOR DAMPIMG HORIZONTAL ACCELERATION ACTING ON STRUCTURE AND DEVICE FOR POSITION RETURNING

WIPO Patent Application WO/2006/038313

A1

[PROBLEMS] Since conventionally a quake-absorbing system is provided with a unit for absorbing the horizontal force acting on the structure and a position returning unit separately and composed of a complex internal structure and precise components including a special material and a hydraulic unit, inspection by the manufacturer is required even after installation and a significant burden is imposed to the manufacturer. In order to reduce the costs of manufacture and inspection, the absorption unit and the returning unit are integrated into one body, any special material is not used, and the structure desirably does not include a complex internal structure or precise components. [MEANS FOR SOLVING PROBLEMS] A position returning device is provided with rolls (3, 4) for absorbing the horizontal force acting on a structure are provided between the foundation (1) and the structure (8), a shake is thereby absorbed as the rolling motion of the rolls, roll receivers (2, 6), as a returning unit, supporting the rolls (3, 4) have a concave shape, and the action of the rolls naturally returning to the center of the roll receivers by the gravity is utilized. With this, any special material, complex internal structure and precise components are excluded, and integration is solved. Necessity for inspection by the manufacturer is reduced and necessity to replace the components is eliminated.
