Soft steel core rubber pad steel spring combination shock absorber

Abstract

The invention discloses a soft steel core rubber mat-steel spring combined seismic isolation supporting seat, which consists of an internal part and an external part, wherein the internal part is a soft steel core rubber mat; in the internal part, a high-performance soft steel core is adopted to replace a common lead core, so that the energy dissipation function of the conventional lead core rubber mat is achieved, and the adoption of a lead serving as a toxic substance is avoided; the external part is a high-intensity and high-bearing-capacity steel spring; the steel spring and the soft steel core rubber mat bear horizontal and vertical loads together, and the bearing capability and reset characteristic of the soft steel core rubber mat can be improved under the action of an inside band simultaneously; and the steel spring is always in a tight state in the using process, so that the action of the inside band is brought into full play. In consideration of the advantages of low manufacturing cost and superior performance of the novel combined seismic isolation supporting seat and along with the continuous importance to the seismic isolation design of an engineering structure worldwide and continuous development of infrastructure construction, the supporting seat can be widely applied to various engineering structures.

Description

technical field [0001] The invention relates to a novel combined shock-absorbing and isolating support, which is especially suitable for use in large-scale civil engineering structures in earthquake-prone areas, so as to effectively control the earthquake response of the structure and reduce earthquake disasters. Background technique [0002] Earthquake is a sudden natural disaster that endangers people's life and property, and has caused very heavy loss of life and property in the world. my country is one of the earthquake-prone countries in the world. For example, the Tangshan earthquake in Hebei Province on July 28, 1976 had a magnitude of 7.8 and killed more than 240,000 people. Houses, industrial plants and equipment, urban construction, transportation, and hydropower facilities in the strong earthquake area were severely damaged. destroy. The magnitude 8.0 earthquake in Wenchuan, Sichuan Province on May 12 this year was the most destructive and widest-reaching earthqu...
