Multi-dimensional shock-absorption support

Abstract

The invention discloses a multi-dimensional shock-absorption support. The multi-dimensional shock-absorption support comprises an upper top plate and a lower bottom plate, a plurality of spring sleeves and middle cylinders which are fixedly arranged on the lower surface of the upper top plate, and central columns which are fixedly arranged on the upper surface of the lower bottom plate. The central columns are partially arranged in the middle cylinders, gaps are formed between the upper ends of the central columns and the upper top late, and gaps are formed between the bottom ends of the central cylinders and the lower bottom plate. A vertical damping system is arranged between a spring sleeve and the lower bottom plate, and a transverse damping system is arranged between the central cylinders and the central columns. The support provided by the invention provides the restore force and damping in the horizontal and torsional directions in earthquake, has characteristics of self-recovery in directions and strong energy consumption property, can protect the upper buildings in earthquake, and solves the problem that traditional shock-absorption support cannot realize multi-direction shock absorption in large earthquake.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a shock-absorbing support for buildings. Background technique [0002] Building structure foundation seismic isolation technology has achieved remarkable research results, and has been widely used in practical engineering. At present, the research on horizontal seismic isolation is relatively deep at home and abroad, and many practical seismic isolation technologies are also horizontal seismic isolation technologies, and there are very few researches on vertical seismic isolation. However, the vertical effect of earthquakes is often considered in the design. Many earthquake damage phenomena show that in high-intensity earthquake areas, especially near the epicentre, the main destructive force on buildings comes from vertical acceleration, while the horizontal direction The impact is small. According to a large number of strong earthquake records at home and abroad, dur...
