Compared with prior art, the utility model between pillar and stopper slot and pedestal and moving steel plate by will set
Into sliding friction pair, alleviate suffered vibrations by sliding, and pillar is carried out with stopper slot it is spacing, by pillar
Buffer spring is set and stopper slot between, bearing can be allowed to be automatically reset after the completion of buffering is shaken, do not needing manually
It is adjusted, reduces the maintenance cost of bridge.By setting shock insulation Buffer Unit, the shock insulation buffer substrate tablet in shock insulation Buffer Unit
Constraint is produced to the transversely deforming of rubber buffer plate using sandwich clad steel, very big vertical rigidity is made it have, while interlayer steel
Plate does not influence the detrusion of rubber buffer plate again, maintains the intrinsic pliability of rubber, makes it have obtain smaller than vertical rigidity
Many horizontal rigidities, and extension bridge structure level natural vibration period so that bearing possesses vertical support and horizontal seismic isolation machine
The dual-use function of structure；By setting the lead for retractable pencil post being circular layout in shock insulation buffer substrate tablet, absorbed using the detrusion of lead for retractable pencil
Dissipate the energy function for shaking, and its anti-seismic performance is improved, while resistance can be selected by adjusting the diameter or sectional area of lead for retractable pencil
Buddhist nun, thus bearing with larger flexibility.In sum, the utility model has energy after preferable anti-seismic performance, deformation
The characteristics of enough automatically reseting and reduce bridge inspection and maintenance cost.
In addition, being arranged to circular arc concave surface by by spacing groove bottom, it is convex that pillar lower surface is arranged into corresponding circular arc
Face, the frictional force between increase pillar and stopper slot, while arc surface structure can also make pillar be easier to reset.By in base
Seat, moving steel plate and fixation steel plate outside set protective paint layer, can cause that bearing is difficult the oxidation that is corroded, extension bearing
Service life.
