Description
Technical field
The present invention relates to ambient vibration and antidetonation, cushion technique field, and in particular to a kind of vertical earthquake isolating equipment, for
Common building thing, special construction, bridge and plant equipment damping/shake.
Background technology
Violent earthquake is one of serious natural calamity for threatening the mankind.Seismic isolation structure system by extend superstructure from
Shake cycle increase structural damping, reduce the earthquake response of structure, it is ensured that superstructure still can be at elastic shape in violent earthquake
State, or it is maintained at the A-stage of elastic-plastic deformation.Seismic isolation technology not only ensure that the safety of structure in itself, also protect structure
Internal unit, facility.But during horizontal seismic isolation design, scholars typically pay attention to horizontal earthquake action, ignore vertical seismic action
Effect, the isolated component being commonly used can only level of isolation earthquake, there is no isolation effect for vertical seismic action.And it can put
Big vertical seismic responses.Therefore it is regional in the larger highlight lines of Vertical Earthquake Loads, although using horizontal earthquake after seismic isolation technology
Effect can substantially reduce, but Vertical Earthquake Loads are likely to become the major control factors of structural response and cause degree of safety to drop
It is low.
Earthquake disaster macroscopic appearance shows that the influence of Vertical Earthquake Loads is it is also obvious that its value is also very considerable.Structure is erected
Mainly caused to geological process by P wave, the spread speed of compressional wave is typically fast compared with shear wave, so the center that earthquake occurs
Feeling for people is first to pitch, rear double swerve.In seismic centre area, building is first by vertical earthquake, then bear
Horizontal earthquake action, and during earthquake vertical component it is general all prior to level to reaching its maximum.In high intensity Zone (especially
It is epicentral area), earthquake disaster phenomenon shows, the vertical component of acceleration of earthquake motion is to the collapse state of building and destructiveness
Influence is obvious.Seismic monitoring shows vertical seismic action peak accelerator be present and meet or exceed acceleration peak
Earthquake record.In terms of strong-motion earthquake observation data, the vertical component of strong earthquake motion has more radio-frequency components than horizontal component.It is near
Nian Lai, the earthquake record that vertical peak accelerator meets or exceeds acceleration peak is obtained.Therefore vertical seismic action
Influence to works can not be ignored, and sometimes more than horizontal earthquake, and because structure vertical rigidity is big, it is perpendicular for its effect
It is close with the vertically seismic wave predominant period to the natural period, thus the vertical vibrant characteristic of structure receives much concern.
Similar to the damping mechanism of horizontal seismic isolation, in order to reach obvious vertical damping effect, vertical earthquake isolating bearing should
With relatively low vertical rigidity, there is higher vertical bearing capacity and vertical damping again, larger vertical change should be able to also occur
Shape.Three-dimensional isolation device for isolating earthquake and vibration simultaneously, due to coupling for horizontally and vertically effect of vibration so that should be every
Shake device turns into international headache.At present, for being mitigated horizontally and vertically by inventing a uncertain three-dimensional shock isolation support
Geological process had had many trials.Many three-dimensional isolation devices all have good vertical earthquake isolating performance or damping and amortization
Can, but can not be ignored the shortcomings that these equipment, because they are very expensive, and comparatively shape matching is big, from
And limit the possibility of its large-scale production.
The content of the invention
Existing common shock isolating pedestal is reacted substantially without reduction for vertical seismic action, the difficult point of vertical earthquake isolating be device compared with
Contradiction between small vertical rigidity and larger support force.In order to solve prior art problem, there is provided a kind of vertical earthquake isolating dress
Put, as long as the rigidity of reasonable selection horizontal support spring, the device can overcome within the specific limits less vertical rigidity with
Contradiction between larger support force, vertical quality and gravity are decoupled.Under normal condition, the vertical holding power of bearing is put down with gravity
Weighing apparatus, system be in static balancing state, and under Vertical Earthquake Loads, additional deformation occurs in equilbrium position for bearing, generation restoring force,
For balancing the vertical inertia force of superstructure, in the range of certain vertical deformation, system is in dynamic equilibrium state all the time,
So as to realize vertical earthquake isolating.After the bearing combines with common shock isolating pedestal, energy while shock insulation three direction compinents and ambient vibration, adopt
With the bearing by protection structure or equipment, shake/vibratory response and shake/vibration under earthquake/effect of vibration transmit to obtain
Effectively control, protect the safety under earthquake/effect of vibration.
