Composite type three-way intelligent seismic isolation support

Abstract

The invention provides a composite three-way intelligent shock-isolation bearing, which is suitable for building construction, bridges, bases of important cultural relics and other different shock-isolation systems. The upper part of the six shape memory alloys is connected to the prismatic steel top plate through the fixed sleeve, and the lower part is connected to the prismatic steel bottom plate sprayed with damping materials. At the same time, the six disc springs on the prismatic steel bottom plate and the intelligent friction plate jointly support the prismatic steel top plate. When the bearing is subjected to a horizontal earthquake, the upper and lower steel plates move horizontally relative to each other, and the shape memory alloy provides a large restoring force, and drives the friction disc to change the anchoring force of the bolt through the electric deformation of the piezoelectric driver, and exerts intelligent adjustment of the horizontal friction Energy dissipation; when the support is subjected to a vertical earthquake, the disc spring bears the load and deforms, and stores a certain potential energy to consume the vertical earthquake force. The composite three-way intelligent shock-isolation bearing of the invention can effectively solve the three-way shock-isolation problem of structures, and provide guarantee for the safety of building structures and the protection of 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...
