Vertical seismic/vibration isolation supporting seat

Abstract

The invention discloses a vertical seismic / vibration isolation supporting seat. The vertical seismic / vibration isolation supporting seat comprises four steel cylinders; the first steel cylinder is connected with a lower foundation through lower anchor rods, a lower baffle is fixed to the lower portion inside the first steel cylinder, and a first through hole is formed in the lower baffle; a top plate is fixed to the top edge of the second steel cylinder, a second through hole is formed in the bottom end of the second steel cylinder, and the top plate is connected with an upper structure through upper anchor rods; the second steel cylinder is connected with the first steel cylinder through seismic reduction layers, and a plurality of first belleville spring sets are connected between the second steel cylinder and the lower baffle; the bottom end of the third steel cylinder is fixed to the inner bottom wall of the first steel cylinder, the third steel cylinder penetrates through the first through hole and the second through hole, and an upper baffle is fixed to the top edge of the third steel cylinder, and a plurality of second belleville spring sets are connected between the upper baffle and the second steel cylinder; and the fourth steel cylinder penetrates through the first through hole and is arranged outside the third steel cylinder in a sleeving mode, the top edge of the fourth steel cylinder is fixedly connected with the outer bottom wall of the second steel cylinder, and a third through hole for allowing the third steel cylinder to penetrate through is formed in the bottom of the fourth steel cylinder. The vertical seismic / vibration isolation supporting seat can be effectively applied to various structures for seismic / vibration isolation, and a good seismic / vibration isolation effect is achieved.

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...
