Swing type anti-pulling and self-resetting seismic isolation bearing

Abstract

The invention relates to a swing type anti-pulling and self-resetting seismic isolation bearing. The swing type anti-pulling and self-resetting seismic isolation bearing comprises an upper bearing platform, a lower bearing platform, disc springs and spring resetting steel sheets, wherein a ball bracket is arranged in the center of the upper bearing platform and vertically mounted in a bearing groove of the lower bearing platform; the disc springs are symmetrically arranged on two sides of the ball bracket and mounted between the upper bearing platform and the lower bearing platform, and the spring resetting steel sheets are arranged on the disc springs. The swing type anti-pulling and self-resetting seismic isolation bearing plays a support role without an earthquake action, and transferspressure of an upper structure to a foundation uniformly. Under the action of an earthquake, a building swings wholly to consume the earthquake energy. Meanwhile, the ball bracket of the upper bearingplatform extrudes an EPE material during swing, the EPE material releases energy through deformation, so that the seismic isolation bearing is prevented from being damaged, and integrity of the bearing is guaranteed. After the action of the earthquake is ended, the building resets under the gravity of the building and the torsion of the disc springs.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a swing-type anti-pull self-resetting shock-isolation support. Background technique [0002] The earthquake resistance of traditional buildings relies on improving the strength, stiffness, ductility and other seismic performance of the building itself to ensure the safety of the building and prevent collapse. [0003] In 1972, Yao Zhiping, a Chinese American, proposed to introduce structural vibration control technology in construction projects. Structural vibration control technology refers to the installation of control systems, devices or external forces on a special part of the building structure to adjust the dynamic characteristics of the building to achieve the effect of reducing the dynamic response of the building. [0004] The current swing-type shock-isolation bearing cannot be effectively reset due to excessive swing amplitude, resulting in the danger of ...
