Composite three-dimensional shock isolation support of sandwich rubber-high damping disc spring

Abstract

The invention discloses a composite three-dimensional shock isolation support of a sandwich rubber-high damping disc spring. The composite three-dimensional shock isolation support of the sandwich rubber-high damping disc spring comprises a horizontal shock isolation support, a disc spring vertical shock isolator, a guide rod, a cylindrical viscoelastic damping layer, an external cylindrical vertical connection steel plate, an internal cylindrical vertical connection steel plate, a lower connecting plate, a middle connecting plate and an upper connecting plate. The composite three-dimensional shock isolation support of the sandwich rubber-high damping disc spring isolates horizontal earthquakes through the horizontal shock isolation support, improves certain damping, and reduces vibration of a structure under the effects of the horizontal earthquakes. The disc spring vertical shock isolator isolates vertical earthquakes, the cylindrical viscoelastic damping layer increases damping of the shock isolation support under the effects of the vertical earthquakes, vertical earthquake energy transmitted to the structure by the earthquakes is consumed, and swing of the structure under the effects of the vertical earthquakes is reduced.

Description

technical field [0001] The invention relates to a novel composite three-dimensional shock-isolation bearing, which is suitable for common multi-high-rise building structures. Background technique [0002] Seismic isolation bearing is a kind of seismic isolation (vibration) technology developed in recent years for the bottom of building structures. Its feature is to effectively isolate the horizontal seismic force from being transmitted to the superstructure through the foundation, so as to reduce the level of the superstructure. Vibrations thus effectively protect the superstructure. The existing products are mainly lead-core rubber shock-isolation bearings. A wide variety of seismic isolation bearing products have been widely used in multi- and high-rise isolation structures. Although some breakthroughs have been made in the study of multi-dimensional earthquakes, they are rarely applied in practice. At present, the theoretical level that is more maturely applied to the c...
