A vertical vibration isolation/vibration support

Abstract

The invention discloses a vertical vibration isolation / vibration support, which comprises four steel cylinders; the first steel cylinder is connected to the lower foundation through a lower anchor rod, and a lower baffle is fixed on the lower part inside, and the lower baffle is provided with a first Through holes; the top edge of the second steel cylinder is fixed with a top plate and the bottom end is provided with a second through hole, the top plate is connected to the upper structure through the upper anchor rod; the second steel cylinder is connected to the first steel cylinder through the shock absorbing layer; the second steel cylinder Multiple sets of first disc spring groups are connected between the barrel and the lower baffle; the bottom end of the third steel barrel is fixed to the inner bottom wall of the first steel barrel, and passes through the first through hole and the second through hole, and the top edge The upper baffle is fixed; multiple sets of second disc spring groups are connected between the upper baffle and the second steel cylinder; the fourth steel cylinder passes through the first through hole and is sleeved outside the third steel cylinder; the fourth steel cylinder The top edge of the cylinder is fixedly connected with the outer bottom wall of the second steel cylinder, and the bottom is provided with a third through hole for the third steel cylinder to pass through. The invention can be effectively applied to various structures for shock isolation / vibration, and has good shock isolation / vibration effects.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption, and more specifically relates to a vertical 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, the seismic isolation bearings used in buildings are mainly horizontal isolation bearings, but vertical isolation should also be considered, mainly including the following aspects: [0003] 1. In addition to the horizontal component in the ground motion component, there is also a vertical vibration component; [0004] 2. The code cl...
