Description

A kind of spacing bearing of power consumption for carrying Viscous fluid damper
Technical field
It the utility model is related to that building engineering structure subtracts shock insulation and bridge subtracts technical field of isolation.It is used for more particularly to one kind The bearing that can be consumed energy with damping.
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 subtracting the deformation of shock insulation rubber bearing.By the deformation for subtracting separation lead-core rubber during big shake, The resistance of wedge-shaped positive stop and the piston movement of Viscous fluid damper absorb and consume huge seismic energy.
Bearing is important load transfer device, consider in design its there is enough bearing capacities with ensure it is safe and reliable will branch Seat counter-force (vertical force and horizontal force) passes to substructure;Secondly constraint of the bearing to bridge deformation (displacement) should be as far as possible It is small to adapt to the needs freely to stretch of beam body, otherwise will produce second inner force inside it for redundant structure, structure is made Into damage, structure service life is greatly shortened.
Utility model content
The purpose of this utility model is in view of the shortcomings of the prior art, taking into full account performance-based anti-seismic design theory On the basis of, there is provided one kind, which has, can be achieved horizontal shock-absorbing function, good antihunt action, can reduce impact of the dynamic load to structure The bearing of effect.The utility model is a kind of simple structure, easy for installation, energy consumption effect is good, has buffer capacity.Running into ground When shake acts on, structure lateral displacement is larger, when reaching certain displacement to top structure lateral displacement along bridge, first with piston Bar moves, dissipation energy;When direction across bridge is subjected to displacement by block come spacing.Concrete technical scheme is as follows:
A kind of spacing bearing of power consumption for carrying Viscous fluid damper, including upper and lower reinforcement steel plate, in addition to upper reinforcement steel The upper junction plate and the lower connecting plate of lower reinforcement Interal fixation that plate is fixed, are located among bearing with what upper and lower connecting plate was fixed Lead rubber bearing;Set in the piston joint element for bar that is connected with to setting of suitable bridge of upper reinforcement steel plate and in direction across bridge Put the upper wedge-shaped positive stop being connected with, the lower cylindrical viscous damping strengthened steel plate and be connected with along bridge to setting The lower wedge-shaped positive stop, piston rod or so that device main body and direction across bridge are connected with stretches into tool after holding through piston joint element for bar Have in the viscous damper main body of viscosity liquid;Upper and lower wedge-shaped positive stop is staggered, and rubber is installed between wedge-shaped positive stop Glue protects cushion;The lead rubber bearing includes being arranged on the lead for retractable pencil in centre position, sorrowful with buffering outside the lead for retractable pencil Layer is abutted, and the cushion includes rubber layer and steel plate layer, and the rubber layer is set with steel plate layer staggered parallel;On the outside of cushion Covered by rubber;
Lead rubber bearing and upper and lower reinforcement Interal fixation, fixed mode are that upper and lower connecting plate sets through hole, Bolt passes through the through hole and upper and lower reinforcement Interal fixation.
The piston joint element for bar includes the annular connecting portion at both ends, and the ring-type that the piston rod includes intermediate projections is spacing Portion, the limiting section are embedded in the annular connecting portion, and the bar portion at piston rod both ends passes through described annular connecting portion.
Rubber spacer is set between the ring-type limiting section and annular connecting portion.
The utility model has the advantage that.
1) can be achieved to be consumed energy from speed and the direction of displacement two:Superstructure is allowed to have one in the effect undersetting such as temperature Quantitative thin tail sheep;Very big acceleration can be produced when running into geological process, viscous damper is velocity profile damper, can be produced Raw very big damping force produces the effect of power consumption, and the lead for retractable pencil under geological process during generation larger displacement in rubber will be surrendered So as to dissipation energy, play a part of in terms of speed and displacement two while consumed energy.
2) larger displacement can be limited:By Viscous fluid damper and wedge-shaped catch carry out to along bridge to and direction across bridge limit Position.
3) the bearing life-span is improved:There is rubber spacer in piston rod and piston joint element for bar, can move to a certain extent Flexing and then protection Viscous fluid damper will not occur so as to play protection piston rod under earthquake motion effect, and in temperature lotus Carry and Braking under will not be to vertical and horizontal make superstructure generation additional stress to spacing and can also pass through rubber Certain power consumption effect is produced, the root of wedge-shaped catch is wider compared with other rectangular block bottoms, when ensure that bottom shearing is very big Also it will not damage, further block be protected and dissipated seismic energy equipped with rubber protection cushion between block.
4) designability is strong:This bearing can be by changing bending for coefficient of viscosity c and wedge-shaped catch in Viscous fluid damper Intensity is taken to realize different yield forces, yield displacement, meets each class formation needs.
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.After running into the structure lateral displacement of larger earthquake masterpiece used time and reaching certain value, each damper dissipation seismic energy, 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 well Protective effect.
6) rationally offset and reduce geological process:Because the side of wedge-shaped catch is inclined-plane, horizontal earthquake under geological process Power is resolved into perpendicular to block side and parallel to block side component, and the component parallel to block side is quilt obliquely The gravity of superstructure is offset, and then reduces the active force to block.
