Abstract

The invention relates to a three-dimensional seism isolation system, which comprises preburied parts, first horizontal limit springs, a connecting plate, a horizontal slide bearing sliding plate, a horizontal slide bearing slider, upper slope leveling connecting plates, flush bolts, lead rubber bearings, second horizontal limit springs, lower slope leveling connecting plates and retaining blocks. Vertical seism is isolated by the deformation displacement of the inclined lead rubber bearings; horizontal seism is isolated by the sliding of the horizontal slide bearing slider; restoring force is supplied by the springs, and thereby the purpose of three-dimensional seism / vibration absorption is realized. The novel three-dimensional seism isolation system can protect protected objects of an upper building during horizontal and vertical vibration and seism and effectively attenuate the vibration transmission of vibrating equipment. The three-dimensional seism isolation system is applicable to the seism and vibration control and protection of building structures and large equipment.

Description

technical field [0001] The invention relates to a three-dimensional shock isolation device, which relates to the technical fields of environmental vibration, shock resistance and shock absorption. Background technique [0002] With the development of modern industry and the expansion of city scale, environmental vibration and noise problems caused by many vibrations of industrial equipment and rail transit have gradually emerged. Vibration has become one of the seven major public hazards affecting human life and production. Vibration has a great impact on people's living and working environment. For example, the vibration of industrial equipment has an impact on the surrounding building production, the performance of precision equipment and instruments, and the living environment of houses. How to reduce the impact of external vibration on people's daily life and precision equipment, the design of vibration reduction is of great significance. [0003] Earthquake is one of ...
