Composite type three-way intelligent seismic isolation support

Abstract

The invention provides a composite type three-way intelligent seismic isolation support suitable for bases of house buildings, bridges, important cultural relics and other different seismic isolation systems. A prismatic steel top plate is connected on the upper portions of six pieces of shape memory alloys, and a damping-material-sprayed prismatic steel bottom plate is connected on the lower portions of the six pieces of shape memory alloys; and meanwhile six dish-shaped springs on the prismatic steel bottom plate and intelligent friction discs jointly support the prismatic steel top plate. When the support bears the horizontal earthquake action, the upper steel plate and the lower steel plate conduct horizontal relative movement, the shape memory alloys supply large restoring force and drive the friction discs to change bolt anchoring force through electro-deformation of a piezoelectric actuator, and the function of intelligent adjusting of horizontal friction energy consumption is played; and when the support bears the vertical earthquake action, the dish-shaped springs bear load and deform to store certain potential energy so as to consume vertical seismic force. According to the composite type three-way intelligent seismic isolation support, the structural three-way seismic isolation problem can be solved effectively, and guarantee is provided for the safety of building structures and the protection of the important cultural relics.

Description

technical field [0001] The invention relates to a structural vibration control shock-isolation device, in particular to a composite three-way intelligent shock-isolation support, which can be used in shock-isolation systems of different structures such as buildings, bridges, and cultural relic bases. Background technique [0002] As a natural disaster, earthquakes can easily cause the collapse of various buildings (structures), the destruction of important cultural relics, the interruption of transportation and communication, and the destruction of other lifeline projects, resulting in the loss of human life and property. my country is an earthquake-prone country. According to relevant statistics, the number of earthquakes in my country accounts for about 33% of the total number of continental earthquakes in the world. On average, more than 30 earthquakes of magnitude 5 or above occur every year, 6 strong earthquakes of magnitude 6 or above, and large earthquakes of magnitude...

AI Technical Summary

Problems solved by technology

[0005] The present invention proposes a design of a composite three-way intelligent shock-isolation bearing for the problems that the horizontal shock-isolation performance of the current shock-isolation device is not significant and the vertical shock-isolation consideration is less.
