Description
Technical field
It the utility model is related to that civil engineering structure subtracts shock insulation and bridge subtracts technical field of isolation.Propped up more particularly to one kind
Seat.
Background technology
To ensure building and the lifeline engineering such as bridge plays due function in earthquake, earthquake disaster reduction, and
Using " no damage in small earthquake, middle shake can repair, shake greatly less than ", three levels is targets of setting up defences, when structure suffers from middle or small earthquake intensity earthquake, according to
Earthquake energy is absorbed by the deformation of structural elements.But fully rely on structure during big shake and its component is difficult to absorb and disappeared
Consume huge seismic energy.
Utility model content
Bearing is important load transfer device, and it is safe and reliable to ensure should to consider that it has enough bearing capacities in design first
End reaction (vertical force and horizontal force) is passed to substructure by ground；Secondly constraint of the bearing to bridge deformation (displacement) should use up
It is possible small to adapt to the needs freely to stretch of beam body, otherwise second inner force will be produced inside it for redundant structure, it is right
Structure causes to damage, and greatly shortens structure service life.
The utility model utilizes spring and shearing-type damping to enter plastic yielding state stage by stage, in advance in structure, to subtract
Lightly shake the damage to caused by structure.The purpose of this utility model is in view of the shortcomings of the prior art, to be based on taking into full account
On the basis of performance-based seismic design theory, there is provided one kind, which has, can be achieved horizontal shock-absorbing function stage by stage, good antihunt action,
Bearing of the dynamic load to the percussion of structure can be reduced.Concrete technical scheme is as follows：
One kind consumes energy spacing bearing, including upper local strengthening steel plate, lower local strengthening steel plate stage by stage, in addition to upper office
Portion strengthens the shearing type damper that steel plate is connected with, and the laminated rubber bases among bearing, strengthens steel plate with bottom
The L-type steel block being connected with, the spring-damper between shearing type damper and L-type steel block；Anchor pole is by upper office
Strengthen steel plate, lower local strengthening Interal fixation in the structure of upper and lower part in portion；Spring-damper left and right ends are respectively with bolt with cutting
Cut 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 resistance
Buddhist nun's device includes connecting plate, and connecting plate bolt is connected with upper local strengthening Interal fixation；Connecting plate passes through with plate below lower section
Riser is fixedly connected；The riser is threaded hole, and multiple support plates parallel with connecting plate are set between connecting plate and lower panel；Institute
Stating spring-damper includes outer barrel, inner cylinder, and inner cylinder can slide in outer barrel；The outer barrel, inner cylinder and the end plate of both sides are fixed, institute
State and through hole is set on end plate, bolt is screwed spring-damper and shearing type damper after passing through the through hole with the screwed hole
It is integrally fixed；Spring assembly is set in the inner space of the inner cylinder and outer barrel, the spring assembly includes the pad at both ends,
The pad of axle one end is fixed, axle other end pass through pad after fixed by nut it is spacing；Pocketed springs on axle between two pads,
The axial length of the spring assembly is less than the axial length between two end plates.
The axis of the spring-damper is parallel with upper and lower local strengthening steel plate.
The upper and lower surface of laminated rubber bases and upper local strengthening steel plate, lower local strengthening Interal fixation.
The outer barrel intensity of the spring-damper is higher than the intensity of inner cylinder.
Bearing of the present utility model is less than the axial length between two end plates due to the axial length of spring assembly, normal
In the case of, it is allowed to laterally there is certain movement, avoid generation second inner force；When running into geological process, structure lateral displacement
It is larger, when superstructure sidesway reaches certain displacement, spring-damper compression, dissipation energy are driven first；Work as side
When movement continues to increase, power and displacement are passed to shearing type damper by the sleeve of spring-damper, and shearing type damper is carried out
Second stage damping is consumed energy.Carry out the transverse shearing force dissipation seismic energy suffered by resisting structure, realize the purpose for reducing lateral displacement,
So as to reduce the earthquake response of structure, structure is played a very good protection.
This bearing has the advantage that.
1) can be achieved to consume energy stage by stage：Structure is allowed to have a certain amount of thin tail sheep in the effect undersetting such as wind load；Small shake is made
Under, upper and lower local strengthening version drives bearing compression spring, dissipation seismic energy；Under big shake effect, L-type steel block drives spring
The outer sleeve of damper, power and displacement are passed on shearing type damper, shearing type damper plays a role, dissipation seismic energy
Amount.
2) moderate finite deformation can be limited：Deformed upon by tension to realize that the upper local strengthening steel plate 2 of power 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 larger impact failure in raw elastic-plastic deformation limiting structure.
3) cost is saved：Due between shearing type damper, L-type steel block, spring-damper and local reinforcing plate and
All be connected between each several part, after earthquake only the part of damage need to simply be changed, it is relatively cheap, can save into
This, without carrying out cumbersome and very long reset work.
4) designability is strong：This bearing can be damped by changing the diameter of steel rim of spring and shearing-type in spring-damper
The model of device realizes different yield forces, yield displacement, meets the needs of each class formation.
5) there is buffer capacity：This bearing 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 running into the structure lateral displacement of larger earthquake masterpiece used time, each damper is classified dissipation seismic energy
Amount, and limiting structure displacement, the effect of buffering and limitation is realized, so as to reduce the earthquake response of building structure, structure is played
Good protective effect.
