Multidimensional seismic isolation layer/belt structure applicable to multilayer construction foundation

Abstract

A multidimensional seismic isolation layer / belt structure applicable to a multilayer construction foundation is characterized in that in the multidimensional seismic isolation structure, a seismic isolation layer is arranged at the bottom part of a building (between a ground base and a foundation) to prevent seismic waves; a slipping seismic isolation layer is arranged between the upper part of the building foundation and a foundation ring beam, so that seismic horizontal shear waves can be absorbed and relieved through slippage; meanwhile, a seismic isolation belt is arranged between the periphery of the building foundation and the soil layer to absorb and relieve the seismic horizontal waves, so that the seismic isolation layer arranged below the foundation and the slipping isolation layer arranged above the foundation can act together with the seismic isolation layer at the periphery of the foundation to prevent the acceleration peak value transmitted to the building and the predominant period leaving the site, influences of the seismic waves on the building are significantly reduced, and further the purposes of protecting house structure and equipment in the house from being damaged by the seismic and guaranteeing lives and safety of personnel in the house are achieved.

Description

technical field [0001] The invention relates to building shock-isolation technology, in particular to a multi-dimensional shock-isolation layer and belt suitable for multi-storey building foundations. Background technique [0002] Earthquakes are the first of all disasters. The history of natural disasters at home and abroad shows that earthquakes cause incalculable losses to society and people's lives and property. my country is an earthquake-prone area. According to statistics, dozens of destructive earthquakes above magnitude 6 occur in mainland my country every ten years. More than 50% of the land area of ​​my country's mainland belongs to high-intensity areas (seismic intensity above seven degrees). . However, most of the disasters caused by earthquakes are caused by the collapse and damage of buildings. At present, in order to prevent and mitigate earthquake disasters, in addition to exploring earthquake prediction and strengthening earthquake monitoring, more energ...

AI Technical Summary

Problems solved by technology

Most of the technologies used are rubber pads, steel plate clip rubber pads, dampers and other high-end seismic isolation equipment, which are not only expensive, but also require high precision installation, cumbersome construction, and it is not easy to replace the life of seismic isolation equipment, so it is inconvenient to promote

What needs to be pointed out is that although some dampers and rubber pads have been used in some test-isolated buildings in China, most of them have not been tested by major earthquakes in China. It is worth exploring how their effects are, and this is also a difficulty in popularization.
