Abstract
One kind support, wherein every kind of device that can be used as attachment structure system two parts connector, load is transferred to other parts by it as support from a part for system simultaneously, such as, it is basic to it by the weight transfer of bridge or the superstructure of building to substructure, or the weight transmitting of machine.When transmitting load, it can reduce the transmission of the instantaneous shock between two structural member connections and keep the globality of total system；For example, when earthquake is transferred to the superstructure on bridge pier and basis or tsunami attack bridge or the two occurs simultaneously, the globality of bridge structure is protected.
Description
Technical field
The invention discloses a kind of device, it is characterised in that described device is the structure for large-scale industrial and civil architecture system
Part, such as building, bridge or machine and its basis, it has at least one in following three functions：Support the system
Moiety by weight, the different piece of linked system transmits the design external force stream between connected component to ensure the globality of structure
Rather than gravity, while slow down or isolate harmful vibration.
The engineering system such as bridge or building, can be divided into two parts substantially：Superstructure such as spanning beam and bear to set
Count the deck system of live load；Substructure, including bridge pier, pier base and deep basis.Device of the present invention connects this kind of work
The superstructure and substructure of journey system support superstructure and bear the weight of changing load simultaneously.
Background technology
Earthquake is the unexpected changing of the relative positions of the tectonic plate of certain point in the earth's crust, cause to ambient radiation stress wave its cause
In ground vibration.For large-scale work China Democratic National Construction Association structure, such as building or bridge, infringement is essentially from two caused by earthquake is possible
Aspect：Ground acceleration is in inertia force caused by inside configuration, and amplification when may cause mesomerism to caused inertia force.
Obviously, internal inertia force is the key factor for causing structure to be destroyed caused by acceleration.
Ground acceleration can be analyzed to two components of vertical direction (parallel to the direction of terrestrial gravitation) and horizontal direction, can
Characterized respectively by corresponding peak value, " seismic peak ground acceleration " (Peak Ground are referred to as in engineering design practice
Acceleration, it is abbreviated as PGA).According to previous experiences, horizontal direction seismic peak ground acceleration is generally than vertically to big；It is beautiful
The current building construction of state and Bridge Design specification require that any anti-seismic structure should have and are enough to resist seismic peak ground acceleration
Ability, the seismic peak ground acceleration can United States Geological reconnoitre office (United States Geological Survey, letter
Claiming USGS) the geological disaster figure announced calculates, see Fig. 1.The geological disaster figure provides the water in any ground place in the U.S.
The statistical forecast value of flat earthward acceleration peak value, the possibility that the earthquake occurred within 75 years futures exceedes these predicted values are
7.5%.Fig. 2 is the predicted value of the horizontally areal acceleration peak value of East Asia Region.
In Aseismic Design, for example, in the Aseismic Design of bridge, the method generally accepted is when earthquake occurs
Bridge superstructure is isolated with directly being accelerated the substructure of impact by ground.Company between the structure of upper and lower part
Support meanss are connect, for example, bearing, there is provided when being rigidly connected, in whole system, this connection support be typically structure " most
Weak link ".Because as the maincenter for bearing all live load and superstructure weight, when substructure is by ground
During the impact that table earthquake calculates, this connection support and external force stream (inertia-induced force caused by inertia force
Flow) up " mouth of hanging " (" neck ").On the contrary, when support is is flexibly connected, when a certain portion of connection is by external dynamic
When load impacts, coupling part can be temporarily separated, and the corresponding inertia force stream mouth that will hang herein is weakened or, in theory, blocked.
In engineering practice, it is not generally possible to absolutely separate inertia force stream.More real seismic isolation design is actual
On be that tie point between each main part of structural system provides certain flexibility or ductility, with the transmission for inertia force stream of decaying
Temporarily change inherent resonant frequency, avoid the resonance with surface seismic ripple.On the other hand, some industry sciences in engineering practice
It is required that connection support provide it is firm be rigidly connected (robustness) because superstructure may bear it is many not of the same race
The live load of class, such as powerful cross force as caused by hurricane and tsunami.One of Japanese celestial platform earthquake on March 11st, 2011
Painful experience is that many bridges and building are survived after the earthquake of high intensity, but its superstructure is under the rear tsunami impact arrived
Depart from substructure and destroy.
Therefore, Aseismatic Design is isolated on the contrary, the concept of " integrated design " is the potential substantially interior of the present invention with traditional
Hold, integrated design requires certain flexibility to reduce and slow down harmful vibration in tie point and the strong point, while makes general structure
As an integral unit.
Prior art and the brief description of market product application
Earthquake-resistant structure and Bridge Design are most active but also with one of field of novelty in civil engineering industry.With one
Exemplified by three layers of building, Fig. 3 schematically illustrates currently conventional various technologies.The present invention may be used as this in earthquake-resisting support device
Build the aseismatic bearing in the lower left corner.
Bearing belongs to support connector, and according to its function, bearing can substantially be divided into three classes：(i) in conventional mechanical devices
Load connection member, such as cylinder-piston damper, cam-pin-frcition damper etc., its damping damping can pass through shape
The modern technologies such as shape memory alloys and electric transducer are realized；(ii) ordinary construction supports, for example, elastic support, it utilizes shearing
Modulus of elasticity provides horizontal drag；(iii) the concentration shock insulation support based on friction swinging mechanism.
Fig. 4 describes a kind of prior art " acceptor of energy " (international publication number WO97/25520), wherein various saws
The contact surface of tooth form includes waveform and V-arrangement contact surface, and it is designed for the transmission of power, while between the core that framework includes
Do not slide.Obviously, it can be used for Fig. 3 damping shearing force cross-brace but its cannot be used for Gravity support.
Fig. 5 is prior art (Application No. US4187573), and it utilizes the damping vibration of elastomer 5, while framework 11 limits

Technology (international publication number WO2008/004475), it is a kind of change of traditional elastic support, its critical component is composite block,
The composite block is made up of elastomer 2b and boss 2c layer structure, and the core 3 at composite block center is made up of high moulding material.Afterwards
The effect of person is reinforcement horizontal distortion drag while improves damping capacity.When the material of core is lead, this bearing is also referred to as " lead
Core rubber " (LRB).But when structure undergoes strong ground motion, the frictional resistance between elastomer and supporting plate
Not enough contend with sliding force caused by inertia force.Once being slided after core deformation, then no inner principles return support
Multiple original-shape.
Fig. 7 is prior art (Application No. US6021992), referred to as friction pendulum sliding support (FPS is in abbreviation).It belongs to
One group of application for including 12 United States Patent (USP)s and ten other countries' patent applications for being based primarily upon the pendulum shown on the right side of picture, its
Utilize horizontal inertial force caused by the weight of superstructure as natural force resistance ground motion.Once such as the acceleration of ground motion
Degree terminates, and gravity makes support recover to its home position.
For in theory, pendulum be it is a kind of will not dissipation energy systems stabilisation.Therefore, if do not rubbed, in practice
Pendulum will be swung always once starting around its resting position.Therefore, it is also friction pendulum sliding support to contact the friction between surface pair
(FPS) a kind of key mechanism in, it requires sizable contact zone to ensure that enough frictional force and energy drive are very heavy
Superstructure.On the other hand, at least such as the curved surface of the certain altitude of base supported in Fig. 7, be it is necessary, it is enough to obtain
Horizontal drag.
The globality of bottom and superstructure requires that higher bridge is very crucial to skyscraper and architectural characteristic.This be because
In addition to such as hurricane and tsunami these strong external force can directly affect superstructure, to be shaken caused by the motion of level ground
The rotation of superstructure may be caused；The size of this motion is about the ground height and length and width of structure in ratio
Maximum ratio.
In order to obtain the globality of superstructure and substructure, Fig. 8 is another prior art (Application No.
US5669189), it is referred to as anti-shake connector (ANSC).It is actually a kind of laminated elastic support 3 plus cable (muscle) 6 by
Rotating member 21 is fastenedly connected the assembling structure of superstructure and substructure.But to cable (muscle) and can in the technical scheme
Fixed design is rotated to the horizontal restricted effect of rotation slided with high structure.
The content of the invention
According to retrieval file, carry support without gravity in the prior art, it is in sharp pounding and maintains large-scale China Democratic National Construction Association's knot
There is double attribute in terms of the shock insulation of the globality of structure/damping.Application No. US5669189 U.S. Patent application is to be directed to this
The solution of class problem, it is so at least for the light-duty superstructure as family housing；But in the technical scheme
Cable (muscle) and the motion that rotates freely the design of fixed system and make superstructure in level there is flexibility, this motion is led
Relatively low drag of toppling is caused, once the motion occurs, the friction between elastic layer becomes bearing and recovered to reset condition
Resistance.On the other hand, the arrangement requirement equipment of muscle fixed system has relatively large space.
Therefore, it is practical and effective available for building and the anti-seismic structure of transportation structure, the application base in order to provide
A kind of neoteric earthquake-resisting support device is disclosed in following standards and theory：

Embodiment
One embodiment is based on the mechanism of " V-type sliding contact " in Fig. 9, and the mechanism includes the slip of at least one pair of V-type and connect
Contacting surface establishes the contact between the superstructure and substructure of large-scale civilian civil engineering system, when bottom or superstructure
When being acted on by one or more external force, provisionally relative slip is allowed between the structure of top and the bottom, so as to weaken inertia force and guarantor
Protect whole system.Because when having the trend of slip between a pair of surfaces of contact or having slided, the weight of superstructure can cause
The horizontal force reverse along glide direction.This horizontal force is combined with frictional force, is ensured under conventional operating mode and caused by inertia force
Horizontal force is less than static friction and the support meanss composition is fixedly connected during horizontal resistance caused by superstructure weight.Weight is led
For the horizontal resistance of cause by the angle-determining on the V-arrangement slope in Fig. 1 or 2, this is also that can make the support after interim slip separates
Device recovers the driving force of original connected mode.The present embodiment described device forms the subclassification of disclosed technology, and it is referred to as
VEB, VEB represent " V-arrangement resilient support " (V-shape Elastic Bearing).Shown in Figure 11, a Novel sliding pin is designed
It is connected with VEB, meets that the device of aforesaid standards (c) is defined as the second subclass, it is referred to as " VEBSP ", and VEBSP represents " sliding pin
The V-arrangement resilient support of control " (V-shape Elastic Bearing with Sliding-Pin).
Obviously, the inclined angle alpha of V-arrangement resilient supporting unit is key design parameter, which determines the water for causing and sliding and separating
The threshold value of flat power.This horizontal force represents that the horizontal force can all produce corresponding stress point in superstructure and substructure with Q
Cloth, the peak value of stress ratio be,The ratio limitation of the stress will not be caused into damage in allowed limits, such as：
Wherein：σYRepresent that stress is σ under horizontal force Q and design load and dead load effectpeak(Q) surrender of material
Intensity；nQIt is safety coefficient, and nQ>1.Formula (1) actually ensures that total will not surrender, so the α angles of V-arrangement contact surface
According to the threshold value Q for allowing stressTHTo design, QTHBe it is all can application level power Q higher limit, it meets formula (1), both：
Q≤QTHAnd
Referring now to an example：One bridge with four supports, its design the gross mass of live load and superstructure by
4M is represented.QRRepresent horizontal and slide drag, size is (see Figure 17)：
QR=Mg [tan (α)+fr] (3)
Wherein, frIt is the coefficient of friction between V-arrangement contact surface and meshing flake, according to formula (2)：
Q≤Qth (4)
Bring formula (3) into (4) and take equal sign, then meeting the maximum permissible value at the α angles of formula (2) is：
For the serial V-arrangement support meanss of the present invention, second key design parameter is the maximum for allowing sliding distance l
Value, it is determined according to Newton's second law.When these supports are mainly used in building or bridge subtracts shock insulation, as Fig. 1 and Fig. 2 are carried
For the prediction of the horizontal ground acceleration peak value (PGA is in peak ground acceleration abbreviations) in this structure location
Value.Actual seismic includes various frequency κ mostlyi, i=1,2 ... n, ground motion spectrum, but amplitude is added by level ground
The constraint of velocity peak values (PGA).Therefore, one " characteristic frequency " is defined, for example, average value：Represent as follows just
The ground motion spectrum of string waveshape：
So the time t that cross force caused by corresponding inertia force is delivered to each support of bridge is：
It is assumed that work as Qpred(t)>QthWhen, superstructure is in time t0Start to slide, work as t>toWhen, sliding speed is V (t), sliding
Row distance is S (t), so according to Newton's second law：
And
Therefore, possesses the superstructure of V-arrangement resilient support (VEBSP) of sliding pin in time ts-t0It is interior, along V-arrangement contact surface
The sliding distance of lower section is in maximum allowable sliding distance lVERSPIn the range of, and be M by equivalent masssideSlip stopping means

Other embodiments design example
Figure 13 illustrates two kinds of prototypes of V-arrangement resilient supporting unit (VEB)：The left side it is a kind of have it is orthogonal overlapping
Double V-arrangement contact surfaces, it can slow down in the horizontal plane along the vibration of any direction, and it is referred to as V-V shape resilient supporting units (V-
VEB).The a kind of of the right is covered in so as to adapt to the rotation of superstructure on V-arrangement contact surface using U-shaped contact surface, and it is referred to as U-V
Shape resilient supporting unit (U-VEB).Figure 14 is the design example of a U-V shape resilient supporting unit, logical including another
Cross and adjust the contact zone between meshing flake and supporting pad to adjust the embodiment of coefficient of friction therebetween.
In order to the advantages of slowing down vibrations using elastomer or class elastomeric material and reach environmental protection purpose, such as reduce make an uproar
Sound, the unstable risk of this kind of material tension is reduced in practice.This belongs to the V-arrangement elasticity branch of another subclassification of the invention
Support arrangement (VEB), it is referred to as more V-arrangement resilient supporting units (Multi-V Elastomeric Bearing are abbreviated as M-VEB).
Figure 20 gives the design of more V faces shape resilient supporting units.In a pair of V-arrangements contact surface, occur to slide relatively between opposite face
Also separation is produced while dynamic between other opposite faces, this separation extends to elastic layer and tension force may be caused unstable.
Therefore, in Figure 15 design, waveform, it is brilliant, V-arrangement geometrical contact face single attaching space redistribute, it is non-slip
The pass of separation, wherein V-arrangement resilient supporting unit (VEB) can be produced between the single attaching space and multiple V-arrangement opposite faces in dynamic face
Key embodiment and it is related the advantages of retained.This advantage is combined with the premium properties of elastomeric material and may be such that this kind of support
Device turns into the candidate that anti-seismic structure designs in moderate strength earthquake risk region.
Compared with the V-V shapes resilient support (V-VEB) described in Figure 13 (a), Figure 16 describes to be flexibly supported based on V-arrangement
(VEB) concept using single prismatic contact surface slows down the design example of the embodiment of the vibrations of all directions in horizontal plane,
Wherein prism contact surface includes N number of opposite face, and N here is greater than 2 integer；Have between opposite face and horizontal plane therein
Identical or different inclination angle.When vibrations cause slip to separate, with inclined angle alphaFRelative contact in or along side
The opposite face of edge motion can produce slip.For the latter, edge has inclined angle alpha with respect to the horizontal planeE, it is by following
Equation determines：
αEIt is generally smaller than the angle (angles of adjacent facets) of adjacent relative contact.Subclassification V-arrangement
Flexibly support (VEB) and be also referred to as the V contact surface types support meanss (360 ° of VEB) of the slip of 360 degree directions of horizontal plane interior edge " can ".Figure
Design example in 16 is 360 ° of V VEB in 3 folding faces, 4 folding faces and 4 UV types folding faces respectively.
Figure 17 is the design example of the V-arrangement resilient supporting unit (VEB) with sliding pin, and it can adapt to V-arrangement geometric surface
Interior relative separation horizontal as caused by vibrations, and superstructure and substructure are kept as integral installation under sliding pin guiding
In top plate and bottom plate.Limited along the slip perpendicular to the direction of V-arrangement resilient support by the cover plate being packed on top plate.V-arrangement
The subclass of slide bearings is referred to as " the unidirectional V-arrangement resilient supporting unit for possessing sliding pin " (one-way VEBSP).On the contrary, figure
18 be " 360 ° of V-arrangement resilient supporting units for possessing sliding pin " (360 ° of VEBSP), and it is caused along level side that it adapts to vibrations
To relative separation, while ensure the gate oxide integrity of superstructure and substructure.It is sliding in Figure 17 and 18 design example
Dynamic pin can be in the groove of top plate slidably, but it is oriented to by the gap of the lateral Displacement block that is fixed by bolts to bottom plate
Effect.Lateral Displacement block is arranged on top plate and the groove of sliding pin is cut out without essential difference from bottom plate.
Figure 19 illustrate the V-arrangement resilient supporting unit (VEBSP) for possessing sliding pin sliding pin and lateral Displacement block it is each
Kind design example.Cylindrical pin has relatively low contact friction force, but it has strict requirements to the strength of materials and wearability.
Relative motion of the lateral Displacement block to top plate and bottom plate with straight trough is given in vertical direction to be constrained, but needs meticulously to tie up
Shield makes to avoid the caused locking that rubs between the contact surface of the groove of pin and lateral Displacement block；Also require to protect between cotter way and V-arrangement contact surface
Hold specific distance.
For example, for shown in Figure 11 V-arrangement flexibly support or possess sliding pin V-arrangement resilient supporting unit (VEB or
VEBSP), slide and transmitted between a pair of contact surfaces and the opposite face of another separation, glide direction can change.In order to reduce sliding ball
(sliding-kick) influence, it is various shown in design drawing 20 in addition to the vertical dissipation pin (VDP) shown in Figure 12 (a)
Slow down structure.(b) equipment in figure uses the Shape-changeable ring containing damping conductor.The Shape-changeable ring is packed in the end of two opposite sliding pins
Portion, the Shape-changeable ring is stretched or compressed during slip, so as to cause the plastic deformation of damping conductor.The damping conductor is by inertia deformable material
Form, such as lead.The design example of this equipment is given in Figure 21.Equipment shown in Figure 20 (b) and the equipment class in (a)
Seemingly, the equipment simply in (b) figure includes two Shape-changeable rings and damping conductor.
To V-arrangement resilient supporting unit (VEB) and possesses the V-arrangement resilient supporting unit (VEBSP) of sliding pin, it is suitable to select
The corresponding equipment of material manufacture, to meet condition (i) intensity；(ii) fatigue durability；(iii) frictional behaviour, including tool
The coefficient of friction and wearability of body；(iv) rigidity, (v) absorb and slowed down the ability of energy, (vi) corrosion resistance.
Traditional elastomeric materials as bridge and building structure can also serve as the making material of the meshing flake between V-arrangement contact surface
Material, such as the model shown in Figure 15 are such.Because coefficient of friction is high, when using Elastic Meshing piece, V-arrangement resilient supporting unit
(VEB) or other mating materials of V-arrangement resilient supporting unit (VEBSP) for possessing sliding pin will not produce separation.Generally speaking,
The metal surface that elastomeric material is commonly attached to support uses；Slip between metal surface and elastomeric material, which can cause, causes bullet
The localised tension of property material failure is unstable.Obviously, the horizontal drag that the modulus of shearing of elastomer is provided is limited.Cause
This, it is this kind of when by strong ground motion impact to support the effective driving force for lacking self-regeneration.In addition, work as environment temperature
When being down to below zero point, elastomeric material becomes fragile because of relatively low frictional resistance.
In order to avoid the disadvantages mentioned above of this kind of material, while the advantages of using it, another crucial embodiment of the invention is
The concept of " vertical to strengthen ", as Figure 22 is shown, it is referred to as " vertically strengthening resilient supporting unit ", referred to as, VREB.This hangs down
The straight key feature for strengthening resilient support is that a series of pin rods made of high strength elastic material are vertically embedded into elastomer block,
It is referred to as vertical reinforcement pin rod (VRP is in abbreviation)；The both ends of each pin rod respectively can not be free by top plate and bottom plate fastening
Rotate, while top plate and bottom plate are linked together.Because top plate is fixed on superstructure, bottom plate is fixed in substructure,
Therefore the top and the bottom minor structure of system is actually connected into an overall structure by normal pin.When pin rod both ends respectively with top plate
When being fastened with bottom plate, pin rod can not freely rotate around its end, and this transports the horizontal displacement for causing to resist between top plate and bottom plate
Dynamic extra drag, meanwhile, structural system returns to original position after its intrinsic elastic force driving dislocation.In geometric simplified meaning
Taste the convenience increased the benefit and manufactured.Similar with concrete structure, being vertically embedded into pin rod and horizontal metal piece makes elastomer
There is desired rigidity value and damping capacity as compounded rubber.This, which is vertically embedded into pin rod, also has extra structural function
Such as implement vertical prestressing force.
As shown in figure 22, the embodiment for vertically strengthening resilient supporting unit (VREB) is by human hair's superior function
Inspire.The intensity of human hair is actually higher than the intensity of common iron.It is because small that the superpower flexibility of hair and flexibility, which are returned,
Diameter.This feature has inspired the reinforcement pin rod insertion one using high intensity, minor diameter to need double attribute (to isolate and add
Gu) elastomer block idea.Figure 23-25 shows vertical 6 kinds of design examples for strengthening resilient supporting unit (VREB).
Industrial applicibility
The practicality of public technology is illustrated with the text of correlation in figure 3.
