Building vibration damping device

Abstract

This invention discloses a building vibration damping device, including an arc-shaped rotary disc and a ball bearing assembly. The outer surface of the arc-shaped rotary disc supports the bottom of the building. The bottom of the ball bearing assembly is fixedly connected to the reinforcing steel of the ground beam, and the top of the ball bearing assembly rolls in contact with the inner surface of the arc-shaped rotary disc. This building vibration damping device improves its vibration damping performance by enhancing the stability of the building on the device. Furthermore, it eliminates the need for additional ground piles or beams to install the arc-shaped rotary disc, and also eliminates the need for dust covers to prevent dust from entering the arc-shaped rotary disc and affecting the normal operation of the ball bearing assembly. This significantly simplifies the construction process, reduces installation costs, and meets the user's needs.

Claims
