A three-dimensional shock isolation/vibration bearing

Abstract

The invention discloses a three-dimensional shock-isolation / vibration bearing, which comprises four steel cylinders and lead rubber bearings; the bottom end of the first steel cylinder is connected to the lower foundation through a lower anchor rod; a lower baffle is fixed inside; the second There is a top plate along the top edge of the steel cylinder; the second steel cylinder is connected to the first steel cylinder through a shock-absorbing layer; the first disc spring group is connected between the second steel cylinder and the lower baffle; the third steel cylinder and the first steel cylinder The inner bottom wall is fixed, and the upper baffle is fixed on the top edge; the second disc spring group is connected between the upper baffle and the second steel cylinder; the fourth steel cylinder is sleeved outside the third steel cylinder; the top edge is connected to the second steel cylinder. The two steel cylinders are fixedly connected, and the bottom is provided with a circular through hole for the third steel cylinder to pass through; the lead rubber support includes two connecting steel plates and lead cores, natural rubber and steel sheets sandwiched between them, and through the anti-corrosion The cable is tightened and secured. The invention can be effectively applied to various structures used for shock isolation / vibration, and has good shock isolation or vibration isolation effect.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, and more specifically relates to a three-dimensional shock-isolation or vibration-isolation support. Background technique [0002] The traditional anti-seismic structure continuously enhances the stiffness and strength of the structure, but at the same time indirectly increases the seismic response of the structure, which is an uneconomical method of anti-seismic design. In construction engineering, the use of seismic isolation bearings can economically and effectively reduce the damage to building structures caused by earthquakes. At present, one kind of seismic isolation bearing used in buildings is horizontal seismic isolation bearing, and the other is vertical seismic isolation bearing. Relatively speaking, the three-dimensional seismic isolation bearing with stronger seismic isolation performance and manufacturing feasibility is still available. Need to impro...
