Three-dimensional seismic isolation bearing with rotating function

Abstract

The invention discloses a three-dimensional shock-isolation support with a rotating function, which includes a horizontal shock-isolation device, a vertical shock-isolation device and an upper cover; the vertical shock-isolation device includes a disc spring shock-isolation assembly and a coil spring shock-isolation assembly, Disc spring isolation assembly includes disc spring guide tube and disc spring group; coil spring isolation assembly includes coil spring guide tube and coil spring group; the lower end of the disc spring guide tube is connected to the horizontal isolation device, and the upper end extends into the upper cover Viscous damping material is arranged in the central casing and between the two; the lower end of the disc spring group abuts against the horizontal vibration isolation device, and the upper end abuts against the ring flange at the opening of the central casing; the lower end of the coil spring guide tube is connected to the horizontal vibration isolation device. The upper end of the device extends into the edge casing of the upper cover; the lower end of the coil spring group abuts against the horizontal vibration isolation device, and the upper end abuts against the annular flange at the opening of the edge casing. The invention has simple design, clear force, can isolate horizontal direction and vertical direction earthquake, and has a certain rotation function at the same time.

Description

technical field [0001] The invention belongs to the technical field of shock isolation of building structures, bridge engineering, etc., and in particular relates to a three-dimensional shock isolation bearing with a rotating function. Background technique [0002] Earthquake disasters bring immeasurable loss of life and property to human beings, and earthquakes seem to be the first of all disasters. In order to reduce the huge disasters caused by earthquakes to human beings as much as possible, it is very important to take effective anti-seismic measures. [0003] With the continuous innovation and progress of technical means, basic seismic isolation technology has developed rapidly in recent years, and some mature seismic isolation technologies have been more and more applied to actual building structures. Ordinary laminated rubber bearings, high-damping laminated rubber bearings, lead core laminated rubber bearings, and sliding vibration-isolation bearings are relatively ...

AI Technical Summary

Problems solved by technology

The difficulty of vertical isolation technology is to ensure the vertical stiffness of the superstructure while selecting an appropriate spring stiffness, so as to increase the natural vibration period of the structure in the vertical direction.
