Translation-type spring friction vibration-isolation support

Abstract

The invention provides a translation-type spring friction vibration-isolation support which comprises an upper component and a lower component fitted with the upper component, wherein the upper component comprises a platform part as well as an upper slide part which is connected to the platform part and located under the platform part; and an upper slide plane is formed on the lower surface of the upper slide part. The lower component comprises a base and an enclosure wall which is connected with the base and located above the base; and a lower slide plane which gets contact with the upper slide plane is formed on the upper surface of the base enclosed by the enclosure wall. When the upper component is fitted with the lower component, the upper slide part is located in space enclosed by the enclosure wall; and a spring is connected between the upper component and the lower component and located on the outer circumference of the enclosure wall. The translation-type spring friction vibration-isolation support provided by the invention is characterized in that the upper slide face is a plane, and setting of a reset device is added, so vibration isolation effects of the translation-type spring friction vibration-isolation support are enhanced.

Description

Technical field [0001] The invention relates to a translational spring friction shock isolation support. Background technique [0002] At present, with the rapid development of construction in my country, in order to reduce earthquake disasters and reduce economic losses and casualties, the degree of earthquake risk that may be encountered by buildings is usually considered during construction. According to the degree of earthquake risk, seismic isolation supports are added to buildings. seat. [0003] The existing friction isolation bearing is the Friction Pendulum System (FPS) proposed by Zayas of the University of California, Berkeley. The FPS is composed of an upper device, a center slider and a lower sliding spherical concave surface. When an earthquake occurs, the central sliding block can slide in the lower sliding spherical concave surface to isolate the seismic energy. However, such a friction isolation bearing has the following problems. [0004] First, because the lower ...

AI Technical Summary

Problems solved by technology

[0004] First of all, since the lower sliding surface is a spherical concave surface, when the stroke of the friction isolation bearing reaches the maximum value, in the longitudinal direction, the upper device will be relatively lifted relative to the lower sliding spherical concave surface, and then the whole bearing will generate a partial Lifting is not conducive to the installation of vertical anti-lifting devices, thus affecting the isolation effect of friction isolation bearings

Secondly, since there is no self-resetting device on the existing friction isolation bearing, when an earthquake occurs, the existing friction isolation bearing has no horizontal self-resetting ability, which will affect the isolation effect of the friction isolation bearing
