Description
Subtract shock insulation the present invention relates to civil engineering structure and bridge subtracts technical field of isolation.More particularly to a kind of support.
Background technique
To ensure to build and the lifeline engineerings such as bridge play due function in earthquake, earthquake disaster reduction, and
It is target of setting up defences with " no damage in small earthquake, middle shake can repair, greatly shake less than " three levels, when structure suffers from middle or small earthquake intensity earthquake, according to
Earthquake energy is absorbed by the deformation of structural elements.However structure is fully relied on when big shake and its component is difficult to absorb and disappear
Consume huge seismic energy.
Summary of the invention
Support is important load transfer device, should consider that it guarantees securely and reliably with enough bearing capacities first in design
End reaction (vertical force and horizontal force) is passed to substructure by ground；Secondly support should use up the constraint of bridge deformation (displacement)
Otherwise the possible small needs to adapt to the free extension of beam body will generate second inner force inside it for statically indeterminate structure, right
Structure causes to damage, and greatly shortens structure service life.
The present invention enters plastic yielding state in structure stage by stage, in advance using spring and shearing-type damping, to mitigate ground
Shake is damaged caused by structure.In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to fully considering based on performance antidetonation
On the basis of design concept, providing a kind of has the function of that achievable horizontal shock-absorbing, good antihunt action can be reduced dynamic stage by stage
Carry the support to the percussion of structure.Specific technical solution is as follows:
A kind of anti-vibration mounts, including upper local strengthening steel plate, lower local strengthening steel plate further include and upper local strengthening steel plate
The shearing type damper being connected with, the laminated rubber bases among support are reinforced steel plate with lower part and are connected with
L-type steel block, the spring-damper between shearing type damper and L-type steel block；Anchor pole by upper local strengthening steel plate,
Lower local strengthening Interal fixation is in the structure of upper and lower part；Spring-damper left and right ends use respectively bolt and shearing type damper,
L-type steel block consolidation；Upper local strengthening steel plate is parallel to each other with lower local strengthening steel plate；The shearing type damper includes connection
Plate, connecting plate bolt are connect with upper local strengthening Interal fixation；Connecting plate is fixedly connected with plate below lower section by vertical plate；
Threaded hole is arranged in the vertical plate, and multiple supporting plates parallel with connecting plate are arranged between connecting plate and lower panel；The spring-damper
Including outer cylinder, inner cylinder, inner cylinder can slide in outer cylinder；The outer cylinder, inner cylinder and the end plate of two sides are fixed, and are arranged on the end plate
Through-hole, bolt screw with the threaded hole after the through-hole and spring-damper and shearing type damper are integrally fixed；
Spring assembly is set in the inner space of the inner barrel and outer barrel, and the spring assembly includes the gasket at both ends, the pad of axis one end
Piece is fixed, and axis other end is fixed by nuts limit after passing through gasket；Pocketed springs on axis between two gaskets, the groups of springs
Axial length between less than two end plates of the axial length of part；The axis of the spring-damper and upper and lower local strengthening steel plate are flat
Row；The upper and lower surfaces of laminated rubber bases is arranged antivibration mat, the antivibration mat by bolt and upper local strengthening steel plate, under
Local strengthening Interal fixation, the upper and lower surface of laminated rubber bases are Nian Jie with antivibration mat integral.
The outer cylinder intensity of the spring-damper is higher than the intensity of inner cylinder.The axial direction of support of the invention due to spring assembly
Axial length between less than two end plates of length allows laterally to have certain movement, avoids generation time under normal circumstances
Internal force；When encountering geological process, structure lateral displacement is larger, when superstructure sidesway reaches certain displacement, band first
Dynamic spring-damper compressive deformation, dissipation energy；When side is mobile continues to increase, the sleeve of spring-damper passes power and displacement
Shearing type damper is passed, shearing type damper carries out second stage damping energy consumption.Carry out the consumption of transverse shearing force suffered by resisting structure
Seismic energy is dissipated, realizes that the purpose for reducing lateral displacement plays good protection to structure to reduce the earthquake response of structure
Effect.
This support has the advantage that.
1) can be achieved to consume energy stage by stage: undersetting allows structure to have a certain amount of thin tail sheep the wind load the effects of；Small shake is made
Under, upper and lower local strengthening version drives support compressed spring, dissipation seismic energy；Under big shake effect, L-type steel block drives spring
The outer sleeve of damper passes to power and displacement on shearing type damper, and shearing type damper plays a role, dissipation seismic energy
Amount.
2) can limit moderate finite deformation: by tension, deformation occurs realizes that the upper local strengthening steel plate 2 of energy consumption, lower part add
Strong steel plate 3 is used as dissipative member, when structure is by geological process, is produced using upper local strengthening steel plate 2, lower local strengthening steel plate 3
There is biggish impact failure in raw elastic-plastic deformation limiting structure.
3) save cost: due between shearing type damper, L-type steel block, spring-damper and local reinforcing plate and
All be connected between each section, after earthquake only the component of damage need to simply be replaced, it is relatively cheap, can save at
This, without carrying out cumbersome and very long reset work.
4) designability is strong: this support can be damped by changing the diameter of steel rim of spring and shearing-type in spring-damper
The model of device realizes that different yield forces, yield displacement meet the needs of each class formation.
5) have buffer capacity: this support allows structure to have a certain amount of water under the horizontal force actions such as wind load, small shake
Prosposition moves.Reach a certain amount of encountering the structure lateral displacement of larger earthquake masterpiece used time, each damper is classified dissipation seismic energy
Amount, and limiting structure is displaced, and realizes that buffering and the effect of limitation play structure to reduce the earthquake response of building structure
Good protective effect.
