Polytetrafluoroethylmaterial material layer.
In the present invention, designed by load metamorphism in advance, after making the three-dimensional isolation/bearing that shakes be installed to shock insulation/shake, dish
Spring is located in state of applanation, and now three-dimensional isolation/the bearing that shakes vertically has the characteristic of quasi-zero stiffness, it is possible to isolate efficiently
Vibration and vertical seismic action；In three-dimensional isolation/bearing horizontal direction of shaking, the lower circular sliding surface made on plate makes three-dimensional isolation/shake
Bearing is when producing horizontal displacement, using the teaching of the invention it is possible to provide level is to restoring force, and frictional force can play the work of dissipation seismic energy simultaneously
With.
In the present invention, vertical at the three-dimensional isolation/bearing bearing that shakes, helical spring and disk spring parallel connection carry, have
Higher vertical bearing capacity.When bearing is installed to that shock insulation/shake layer, disk spring is close to flattening, and bearing is in running order.This
Time, disk spring provides vertical negative stiffness, and helical spring provides positive rigidity, makes system vertically be in zero stiffness after both superpositions
State.The system being in vertical zero stiffness state can separating building ambient vibration and vertical seismic action efficiently.
In the present invention, the three-dimensional isolation/bearing that shakes level to, use friction pendulum form carry out level to shock insulation.When
Bearing produces horizontal displacement, due to the setting of the lower circular sliding surface making plate, it is possible to provides for the three-dimensional isolation/bearing that shakes and replys
Power.In slipping, friction working, it is possible to effectively dissipate inputting seismic energy.
In the present invention, on make plate and in make plate by linear motion guide device, retain enough contacts area, by level with turn
Dynamic degree of freedom is locked, it is achieved level is to the decoupling with vertical motion.Make on bearing plate and in make to be only capable of between plate vertical phase
To displacement, and in make plate and under make between plate can occurred level displacement and corner (i.e. use friction pendulum form carry out level every
Shake).The purpose of mobile decoupling is to ensure the stability of bearing, it is to avoid bearing produces when geological process and excessive waves work
With.
In the present invention, on make plate and in make between plate, middle make plate and under make between plate contact surface and use politef material
The bed of material.Purpose is to realize relatively low contact surface coefficient of friction, can ensure that smoothly under contact surface has bigger pressure condition
Slide.
The ambient vibration problem caused along with urban transportation more causes the concern of people, and the present invention has well application
Prospect, it is possible to simultaneously tackle the Aseismic Design of building and the control requirement to vibration.The model of helical spring, the thickness of disk spring
Degree and size, the parameter such as the radius of curvature of the lower circular sliding surface making plate, all can be according to actual and different the providing fortification against earthquakes of engineering
Target and vibration control demand are designed, and have stronger motility.
In the present invention, the design of vertical quasi-zero stiffness vibrating isolation system (helical spring and disk spring) needs to refer to it and holds
Pressure design load.Purpose one is to ensure that its vertical bearing capacity, two be in order to make bearing be installed to the shock insulation/layer that shakes after,
Disk spring is exactly near pressing displacement, it is possible to form zero stiffness system.
In the present invention, utilize anti-unstability bar helical spring and disk spring to be connected, prevent helical spring in pressure-bearing situation
Under unstability.
In the present invention, level needs to meet the requirements for fortification against earthquake of structure to the design of shock isolation system.Vertical needs meets
Vertical bearing requirements, the lower circular arc equivalence radius of curvature making plate directly determines the natural vibration period of isolation structure, equivalent redius
Choose and should carry out in conjunction with the design analysis of isolation structure.
In the present invention, on make plate and in make between plate by structure level is locked, really to relative displacement and corner displacement
Protect the decoupling of support movement.Both contacts site are it is ensured that enough contacts area are to ensure locked effect.Support movement solution
The purpose of coupling be to make bearing under geological process, on make plate and in make there is no relative level between plate to displacement and corner, keep away
Exempt from bearing excessive wave effect.
The three-dimensional isolation of Novel belt quasi-zero stiffness characteristic/(such as rubber earthquake isolation support, rubs the bearing that shakes with tradition shock isolating pedestal
Wipe pendulum shock isolating pedestal etc.) compare, the invention have the advantage that
(1) vertical earthquake isolating/vibrating system, has the characteristic of quasi-zero stiffness, can play the effect of isolation environment vibration.
(2) vertical earthquake isolating/vibrating system, owing to vertical rigidity is less, can play the effect of isolation vertical seismic action.
The three-dimensional isolation of Novel belt quasi-zero stiffness characteristic/shake bearing and conventional building construction vibration isolation measure (such as thick meat every
Shake bearing, vibration isolation ditch etc.) compare, the invention have the advantage that
(1) under geological process, after the vertical generation micro-deformation of bearing, due to the linear Stiffness that it is stronger, vertical rigidity
Can significantly increase.Thus can avoid traditional vertical vibration isolation measure under geological process, issuable excessive the shaking of structure
Pendulum problem.
(2) traditional linear vibration isolation measure has bearing capacity relatively low in building structure vibration isolation and low-frequency excitation shock insulation is imitated
The most inconspicuous problem.By helical spring and the parallel connection of disk spring, the vibrating isolation system of quasi-zero stiffness has higher vertically holding
Load power.During simultaneously as system does micro breadth oscillation near standing balance position, its dynamic rate levels off to zero, its intrinsic frequency
Rate levels off to zero, it is achieved thereby that relatively low vibration isolation initial frequency, makes system have good anti-vibration performance.
