Three-dimensional isolation support

Abstract

The invention discloses a three-dimensional isolation support. The three-dimensional isolation support comprises a lower connecting plate (1), a horizontal isolation support body (3), an intermediate connecting plate (2), a disc spring vertical isolation device and an upper connecting plate (4) which are arranged from bottom to top in sequence. Vertical isolation is achieved through a viscous fluid damper, a disc spring set, multiple connecting plates, a guiding rod, a limiting bolt, an annular spring and other auxiliary devices, and the connecting plates, the guiding rod, the limiting bolt and the annular spring guarantee the normal conducting of vertical isolation. A traditional isolation support is improved due to the adoption of vertical isolation, vertical vibration and small vertical earthquakes can be resisted, and the structure has certain vertical vibration (earthquake) isolating ability.

Description

technical field [0001] The invention relates to the field of building structure foundations, in particular to a three-dimensional shock-isolation support, which is used for the anti-seismic design of multi-storey building structures with small mass and the vibration isolation application of equipment and instruments sensitive to vibration with small mass. Background technique [0002] Base isolation is a seismic isolation technology developed in recent years for the foundation of building structures. Its feature is to effectively isolate the horizontal earthquake action from the foundation to the superstructure, thereby reducing the horizontal vibration of the superstructure. The existing products are mainly ordinary rubber shock-isolation bearings, lead-core rubber shock-isolation bearings, high-damping rubber bearings, etc. All kinds of seismic isolation bearing products have been widely used in the seismic application of multi- and high-rise building structures. Although...
