ELASTOMERIC BEARING ALLOWABLE FOR THE COMPLEX MOVEMENT

摘要

PURPOSE: A composite elastic bearing which can accept composite movement using a concave-convex coupling structure is provided to improve the earthquake-resistance efficiency by reducing the horizontal force applied to the structure. CONSTITUTION: A composite elastic bearing(100b) which can accept composite movement using a concave-convex coupling structure comprises a lower plate(100), an elastic support(200), a movable block(300), and an upper plate(400). Upward extensions(120) are formed on the top of the lower plate. The elastic support is formed in a shape in which elastic rubber of a block shape is formed, and elastically displaced to the load of a horizontal direction. The movable block has a horizontal plate(330) and a sliding surface(340). The bottom surface of the horizontal plate is attached on the top of the upward extensions to be sliding. The sliding surface accepts the displacement of the horizontal direction of the upward extensions. A globular concave surface(501) is formed on the bottom surface of the upper plate. The globular concave surface is adhered to a globular convex surface(502) formed on the top surface of the movable block to be sliding.
