The specific embodiment

With reference to accompanying drawing, a plurality of embodiment and shown in and in described picture, Reference numeral is used to refer to identical or corresponding parts of generation.In a particular embodiment, corresponding component is indicated by additional subscript letter.The variation of the corresponding component shown in figure has also been described.Should understand general variation in embodiment can exchange not deviating under prerequisite of the present invention.

Fig. 1 has shown the vertical framework storage shelf of typical four pillar system, and it is equipped with below by the storage shelf vibration insulator 20a describing in detail.According to structure, be Design and manufacture how, each storage shelf system has intrinsic frequency.The intrinsic frequency of storage shelf system is also relevant with its intensity, and provides in seismic events storage shelf system by the information of how to react.Conventionally be not equipped with the vertical framework storage shelf system of storage shelf vibration insulator different in the flexibility of all directions.Vertically framework storage shelf system conventionally corresponding to along passageway direction (along the passageway direction that is parallel to the length of storage shelf system, as shown in direction arrow 12) the first horizontal dimension flexibility higher, and conventionally corresponding to lower with the second horizontal dimension flexibility of the crossing direction (the passageway direction forming perpendicular to storage shelf system, as shown in direction arrow 10) in passageway.Definite, the vertical framework storage shelf of the typical case system of being produced by the Ridg-U-Rak company that is positioned at Pennsylvania North East is approximately 0.9Hz along the intrinsic frequency of passageway direction, is approximately 1.6Hz with the intrinsic frequency of the crossing direction in passageway.Estimate that most vertically framework storage shelf systems have similar design, and similarly higher with the crossing directional stiffness in passageway.

During seismic events, storage shelf system vibration is to offset the stress that is delivered to storage shelf system because of measure ground motion, so storage shelf system is waved response earthquake and attempts mobile.These vibrations may cause the damage of storage shelf system, and may cause the article that are stored in storage shelf system to fall storage surface, thus near the people may injuring.The distance according to the earthquake centre of earthquake intensity and storage shelf system and earthquake that is delivered to the vibration of storage shelf system improves.But when the vibration frequency from seismic events surpasses 1.5Hz, the possibility that the possibility that storage shelf system suffers damage or stored article fall from it improves.Because typical storage shelf system has the intrinsic frequency of 1.6Hz with the crossing direction in passageway, not too strong earthquake will destroy them.

The intrinsic frequency that reduces storage shelf system will reduce the impact of seismic events.For reaching this object, must give storage shelf system extra flexibility, and not sacrifice its stability and intensity.This can be by not changing the structure of storage shelf system but changes the mode that storage shelf is connected in ground and reach.There is the storage shelf vibration insulator of earthquake vibration isolation and dissipation structure (its have the first component that is connected in ground and the second component that is connected in storage shelf) as the interface between ground and storage shelf, therefore storage shelf system is connected in storage shelf vibration insulator in one or another kind of mode, rather than is directly connected in ground.

Target be by the intrinsic frequency of storage shelf system be reduced to the destruction of storage shelf system be lowered and storage shelf on the degree that can not fall of stored article.Preferably, the intrinsic frequency of storage shelf system is reduced to below 0.9Hz, or ideally, is reduced to below 0.5Hz.According to the largest anticipated load of the target intrinsic frequency of wanting to reach and storage shelf system, can select to reach the storage shelf vibration insulator of these frequencies.As previously mentioned, typical storage shelf system is generally approximately 0.9Hz along the intrinsic frequency of passageway direction, therefore the intrinsic frequency without remarkable reduction storage shelf system in this direction.But will be useful in some the extra dampings along passageway direction.But preferably storage shelf vibration insulator will reduce the intrinsic frequency of the crossing direction in storage shelf system edge and passageway, simultaneously minimum along the intrinsic frequency impact of passageway direction on storage shelf system.

A kind of method that reduces the intrinsic frequency of storage shelf system is in seismic events, allow storage shelf system responses measure ground motion and move.Such motion, or compliance, improved the overall flexibility of storage shelf system, and for the earthquake of dissipating, be delivered to the energy of storage shelf system.But the acceleration that in motion, storage shelf system stands is also delivered to storage article on the top of the shelf, if article do not tie up in storage shelf, article just have the risk of falling from shelf.Thereby another consideration being therefore applicable in the design of storage shelf vibration insulator of seismic events of certain limit is to control the acceleration of storage shelf system to reduce intrinsic frequency to obtain enough motions, do not improve the limit value of acceleration, surpassing these limit value article will fall from shelf simultaneously.

The energy absorption that in earthquake, the dissipation that passes to the energy of storage shelf system due to measure ground motion is during by storage shelf system responses earthquake campaign, produce due to vibration insulator motion and because magnetic hystersis loss and/or secondary (secondary) fricative energy dissipation obtain.In there is no the storage shelf system of storage shelf vibration insulator, the energy that passes to storage shelf system is directly delivered to storage shelf.Cause for this reason energy cannot dissipate, and does not have the storage shelf system of storage shelf vibration insulator to suffer badly damaged.But in having the storage shelf system of storage shelf vibration insulator, the major part of this energy is used for making storage shelf system motion.Therefore in seismic events, the locomitivity of storage shelf system is as important energy dissipation factor.

In order to realize this motion in seismic events, storage shelf system can not be fixed to ground, and must allow response earthquake vibration and moving.Must control and guide this motion to reduce most effectively the intrinsic frequency of storage shelf system and to carry out damping vibration arrogantly, not allow acceleration too high to such an extent as to force article to fall from shelf simultaneously.Have the various storage shelf vibration insulators that can meet these requirements, it can relate to many different technologies and method.But preferably, storage shelf vibration insulator mainly between the pillar of storage shelf system, along storage shelf system the second lower horizontal dimension of flexibility.Storage shelf vibration insulator is mainly installed between pillar rather than under pillar and means and needn't design many kinds of storage shelf vibration insulators with the load in carrying storage shelf system.This has reduced the wearing and tearing of storage shelf vibration insulator.This also more easily approaches and safeguards storage shelf vibration insulator, because without storage shelf system just can be removed or be changed single earthquake vibration isolation and the dissipation structure of storage shelf vibration insulator unit from raked floor.

Fig. 1 to Fig. 6 has shown how principle of the present invention can be applied to the storage shelf system of all kinds and design.The specific embodiment of the storage shelf vibration insulator shown in Fig. 1 to Fig. 6 is giving an example of the application of the principles of the present invention.Should understand any embodiment disclosed herein and equivalent operating principle thereof similar, even if it is not identical.

Fig. 1 has shown the vertical framework storage shelf of the typical case system 13 that comprises four pillars 14.The pillar of every pair of posts 14 is connected to each other by a few root architecture crossbeams 16 or weight supporting traverse 17.This has produced several accumulation layers, and shelf or other storage platforms can be installed on it.Do not show for simplicity these platforms, but should understand the design of the various storage shelf systems that the present invention is applicable to comprise various storage platform selecting.The design of storage shelf system 13 makes the flexibility of storage shelf itself higher along passageway direction 12, and lower with crossing direction 10 flexibilities in passageway.

Each pillar 14 is connected in and can makes pillar at the shore supports assembly of ground moving.In the embodiment shown in fig. 1, shore supports assembly consists of the slip heelpiece 30a that is connected in the lower end of each pillar 14.Slip heelpiece 30a is positioned on the fixedly heelpiece 32a being connected with ground.Slip heelpiece 30a can fixedly move on heelpiece 32a.In order to allow the motion of storage shelf pillar 14, must consider frictional force.Need a certain amount of power just can make to slide surfacewise in lip-deep object.If promote object but it does not move, frictional force is stiction f _s, it balances each other with the power putting on object.Only (be defined as maximum static friction force f having applied a certain amount of power _{s, max}) after, object just can move.In other words, make object along surface sliding, must overcome a horizontal force.This power f _{s, max}be defined as:

f _s，max＝μ _sF _n

μ wherein _sconfficient of static friction, F _nbe to be applied to lip-deep normal force by object, or for storage shelf system, be to be applied to the gravity that ground storage shelf system comprises its load.

Confficient of static friction μ _sthe character that depends on the contact surface of two objects, or for storage shelf system, be the character of storage shelf system and ground contacting surface.Confficient of static friction μ _slower, make object along the required power f of surface sliding _{s, max}lower.For example the bloom on steel desktop is lower than the confficient of static friction of the block rubber on dry concrete surface.

For storage shelf system can be moved freely in seismic events, need for overcoming the maximum static friction force f between storage shelf system and ground _{s, max}power should be too not high, otherwise likely before storage shelf vibration insulator works storage shelf system damaged.By the slide assemblies with the material structure shore supports assembly of low-friction coefficient, for example slide heelpiece 30a and fixing heelpiece 32a, can reduce power f with the friction factor reducing between them _{s, max}.Low frictional torque bearing material also can be used between slide assemblies and reduces friction factor with help, but any selected material all should have the load that high compressive strength is born to support storage shelf system.

Between slidingsurface, add sliding agent, for example oil or grease, also can reduce friction factor.A shortcoming of doing is like this through after a period of time, and sliding agent may disappear from surface, thereby needs intermittent oiling.In addition, more known oil react with the elastic parts that may be included in storage shelf vibration insulator, have so just reduced their life-span.But found that silica gel is a kind of effective sliding agent, it is on the not significant impact of elastic body.

For any storage shelf vibration insulator, shore supports assembly is all important assembly.The energy that mobile pillar absorbs represents the energy that passes to storage shelf system in seismic events, and it does not act on damage storage shelf, but is converted into the kinetic energy of storage shelf system motion.If need too large power f _{s, max}make pillar motion,, before any motion occurs, storage shelf system is easy to be damaged.If pillar too easily moves, there is the storage shelf unsettled risk that becomes.In addition, the excessive deformation of storage shelf system may cause shelf more to stretch in its contiguous passageway.

The confficient of static friction μ of storage shelf system and ground contact surface _sshould be less than about 0.3, or ideally between 0.05 to 0.1.Determined that the NYCAST kollag that is full of monomer cast nylon (cast nylon) meets the General Requirements as bearing material.Be found to be the supplementary silicone lubricant of this material also effective.But should be appreciated that the other materials that substantially meets these requirements is also suitable for, and is also contemplated that within the scope of the present invention.

Fig. 1 has shown and has inserted slip heelpiece 30a and the fixing low frictional torque bearing material 34a between heelpiece 32a.But as described in, if the material of selected slip heelpiece 30a and fixedly heelpiece 32a has had enough low friction factor so that the movement that storage shelf system can be relatively easy in seismic events can be removed this bearing material 34a.

Although allow storage shelf system to move in seismic events, it is fixed to ground by be connected in storage shelf vibration insulator 20a in one or another kind of mode, and this storage shelf vibration insulator 20a is connected in ground.In seismic events, measure ground motion to storage shelf system transmitting vibrations and energy.Storage shelf system causes shelf to swing at this dimension nature in the intrinsic flexibility along passageway direction 12, these some seismic energies that dissipated.Because storage shelf system is lower with the crossing direction flexibility in passageway, at this one dimension, it can not swing easily.If storage shelf system is fixed on ground, the energy that passes to storage shelf system in the second lower horizontal dimension 10 of flexibility will be stored frame system absorption, and may cause the badly damaged and structure of storage shelf system to be caved in.But storage shelf system has storage shelf vibration insulator, as shown in example in Fig. 1, pillar is not fixed on ground, and quite a few energy that passes to storage shelf system is used to make storage shelf system motion.The design of storage shelf vibration insulator 20a allows storage shelf system along lower the moving and make storage shelf system roughly get back to its starting point with the crossing direction 10 in passageway of flexibility.As previously mentioned, the specific embodiment of the storage shelf vibration insulator 20a of Fig. 1 to 6 demonstration is for giving an example.Any other embodiment described herein or equivalent also can be worked.

Fig. 2 has shown the storage shelf system with six roots of sensation pillar 14, and storage shelf vibration insulator 20a is installed between every two pillars 14 of storage shelf system flexibility direction 10 lower and that passageway is crossing.Fig. 3 has shown the storage shelf system with eight pillars 14, and storage shelf vibration insulator 20a is installed between two pillars 14 of first two pillars 14 of every row and end of storage shelf system flexibility direction 10 lower and that passageway is crossing.Storage shelf system does not need to be restricted to two row's parallel struts as shown in Figures 1 to 3.Fig. 4 has shown the simplification cross-sectional top view of the storage shelf system with three pillars of the every row of three rows, and every pillar has in flexibility direction 10 lower and that passageway is crossing and is installed on the storage shelf vibration insulator 20a between pillar 14.Fig. 5 has shown the cross-sectional top view of the storage shelf system of ten six roots of sensation pillars with four pillars of the every row of four rows, and storage shelf vibration insulator 20a is installed between two pillars 14 of first two pillars 14 of every row and end of storage shelf system flexibility direction 10 lower and that passageway is crossing.

Fig. 6 A to Fig. 6 D has shown the simplification cross-sectional top view the row of lower five pillars 14 of every row that extend with the crossing direction in passageway of storage shelf system flexibility.Fig. 6 A has shown the storage shelf vibration insulator being installed between every pair of adjacent struts 14.According to the characteristic of concrete storage shelf system, not between every two pillars of flexibility direction lower and that passageway is crossing, all need storage shelf vibration insulator 20a.If in the parameter of discussing herein, can obtain enough earthquake dampings by less storage shelf vibration insulator 20a, can use less storage shelf vibration insulator unit 20a, as long as all pillars can move on the ground.For example, Fig. 6 A has shown the row of five pillars, and storage shelf vibration insulator 20a is installed between every two pillars, and Fig. 6 B has shown the similar row who only has three cover storage shelf vibration insulator 20a.Fig. 6 C and 6D have shown the row of similar five pillars that only have two storage shelf vibration insulator 20a, and one of them storage shelf vibration insulator unit 20a is between every end posts 14 and the pillar 14 that is adjacent.In Fig. 6 A to 6D, pillar 14 is connected in and allows its shore supports assembly moving a horizontal direction.Fig. 6 C show slip heelpiece 30a and fixedly heelpiece 32a do not need through and at a row every pillar 14 downward-extensions.The 3rd pillar is arranged on different shore supports assemblies, and this shore supports assembly comprises the slip heelpiece 30f being positioned on fixing heelpiece 32f, and fixedly the size restrictions of heelpiece 32f is that seismic events B-C post is by mobile expectation area.

Should study the design characteristics of the concrete storage shelf system that storage shelf vibration insulator installs to determine acceptable kind, quantity and the combination of the storage shelf vibration insulator that should use.Although some parameter must can only reduce, the intrinsic frequency of storage shelf system for example, should consider to have the different embodiment of the storage shelf vibration insulator of different pluses and minuses.

Schematic diagram in Fig. 7 has shown for being arranged on the basic demand of the storage shelf vibration insulator 20 of ground storage shelf system.As described in, typical storage shelf system has many pillars 14, and higher in the first horizontal dimension (not shown) flexibility, and lower in the second horizontal dimension 10 flexibilities.Each storage shelf vibration insulator 20 is main between the adjacent struts 14 of the second lower horizontal dimension 10 of storage shelf system flexibility.Storage shelf vibration insulator 20 comprises that at least one earthquake vibration absorbs and dissipation structure, and this earthquake vibration absorbs and dissipation structure comprises the first component 24 that is connected in some way storage shelf system and the second component 26 that is connected in some way ground.Pillar 14 is installed at least one shore supports assembly that makes pillar 14 relative ground motions.In Fig. 7, this shore supports assembly comprises the slip heelpiece 30 that is connected in every column bottom.Slip heelpiece 30 is in being arranged on ground fixedly heelpiece 32, but the shore supports assembly of other configurations and kind is also possible, wherein some discussed herein.Or intrinsic by the design of storage shelf vibration insulator 20, or by comprising mechanical part (not shown), the motion of pillar is basic along the second lower horizontal dimension 10 of flexibility by mechanical constraint.

Motion by storage shelf vibration insulator 20 or the energy absorption causing by magnetic hystersis loss or viscous damping and secondary frictional damping, the principle of 20 pairs of energy dissipations of storage shelf vibration insulator works.In other words, the earthquake vibration by storage shelf vibration insulator 20 absorbs and the appropriate effect of dissipation structure, and the part energy that is delivered to storage shelf system in seismic events is not absorbed but disappears.These damping losses are absorbed by earthquake vibration and the physical property of dissipation structure causes, and comprise viscous damping C or have damping intensity K " and the magnetic hysteresis damping of elastic strength K.

Viscous damping C refer to vibrational energy in time with the dissipation of distance.Elastic strength K can be used for the bright general terms in Jie Cixuzhu village, and it refers generally to the opposing of object to distortion or displacement.Material or object are harder, make its distortion or move required power larger.In seismic events, need to overcome the frictional force of shore supports assembly so that the required energy of storage shelf system motion also has contribution to the calculating of viscous damping and elastic strength.In the different designs of storage shelf vibration insulator 20, the combination of these character allows the needs that may design to meet seismic isolation in certain limit.

Fig. 8 has shown the storage shelf vibration insulator 20a that is connected in a pair of adjacent struts 14 in the second lower horizontal dimension 10 of the flexibility of storage shelf system.Storage shelf vibration insulator 20a is the earthquake interruption device of combination, can easily be applicable to existing storage shelf system and obviously changes without it is done.

Comparison diagram 8 and Fig. 9 the most easily understand, and each storage shelf vibration insulator 20a comprises that several earthquake vibrations absorb and dissipation structure, and this earthquake vibration absorbs and dissipation structure comprises the first component that is connected in storage shelf system and the second component that is connected in ground.In this case, earthquake vibration absorbs and dissipation structure is elastic parts 22a, and the first component that is connected in storage shelf system is the first rigid slab 24a, and the second component that is connected in ground is the second rigid slab 26a.Each elastic parts 22a operability is connected in the first and second rigid slab 24a and 26a, like this in seismic events, the first and second rigid slab 24a and 26a maintenance are connected with elastic parts 22a's, and the first and second rigid slab 24a and 26a can move in plane substantially parallel to each other simultaneously.

In this embodiment, each elastic parts 22a consists of three thin slice elastomeric element 28a, has intermediate plate 36a between elastic layer 28a.Elastomeric element 28a is fixedly secured to the first and second plate 24a and 26a and intermediate plate 36a by cohesive material (not shown).Elastomeric material forms firmly in conjunction with being enough to prevent that the first and second rigid slab 24a and 26a and intermediate plate 36a and elastomeric element 28a from disengaging, even when storage shelf vibration insulator 20a is subject to larger external force.Suitable adhesive comprises all to be manufactured by Lord Corporation

8560F,

8210/8560S and

236A, or the stickum of other firm combining that are adapted at providing such between elastic body and the rigid slab of for example metal.Can be contemplated that between elastic layer 28a and the first and second rigid slab 24a and 26a and intermediate plate 36a and to use separately adhesive to be just enough to obtain enough combinations, although also can add packing ring, rectangular gasket for example, and extend bolt or other extra clamping devices.

Elastomeric element is made by the material of the measure ground motion energy that can absorb and dissipate in seismic events.For example elastomeric element 28a can for example, be made by polyisoprene, polyisoprene mixture (polyisoprene blend), butyl rubber, silicon or other high damping elastomers (those that produced by Corry Rubber Corporation of Corry (PA)).Elastomeric element 28a can also be by any elastomeric materials that can stand load and have expectation strength feature described herein.

Storage shelf vibration insulator 20a comprises shore supports assembly, this shore supports assembly it comprise long enough can between two pillars 14 and under the slip heelpiece 30a that extends and fixing heelpiece 32a.Slip heelpiece 30a comprises the upwardly extending pin 58a of a plurality of upper surfaces from slip heelpiece 30a.Otherwise pin 58a can compress assembling and/or welding or be connected in slip heelpiece 30a.When the first rigid slab 24a was positioned at slip heelpiece 30a when upper, aim at each pin 58a to mesh the pin-and-hole 42a of the first rigid slab 24a, during assembling storage shelf vibration insulator 20a, each pin inserts also and extends on the upper surface of the first rigid slab 24a.The first rigid slab is firmly secured to slip heelpiece 30a by base nut 56a.During assembling storage shelf vibration insulator 20a, pin 58a keeps the relative aligning of elastic parts 22a and slip heelpiece 30a.

Limiting part 60a is welded in fixedly heelpiece 32a, has produced the passage that slip heelpiece 30a and the elastic parts 22a having assembled can slip into.If use low frictional torque bearing material, fixedly inserting at least one deck low frictional torque bearing material 34a between heelpiece 32a and slip heelpiece 30a.Determined that the layer of low frictional torque bearing material 34a does not need to extend beyond the length of slip heelpiece 30a, and the shorter section shown in Fig. 9 enough makes pillar 14 slide in seismic events.Although low frictional torque bearing material 34a can be fixed on to slip heelpiece 30a or fixing heelpiece 32a, the embodiment shown in Fig. 9 shows that low frictional torque bearing material 34a is fixed on fixedly heelpiece 32a.Although low frictional torque bearing material 34a can be simply fixing by adhesive, the low frictional torque bearing material 34a that embodiment shown in Fig. 9 shows has shearing projection that casting or machining forms to be arranged in the corresponding aperture of fixing heelpiece 32a.This helps fixedly low frictional torque bearing material 34a, and has reduced low frictional torque bearing material 34a and the fixing amount of required adhesive between heelpiece 32a.

The second rigid slab 26a have with limiting part 60a in the screwed hole 44a of corresponding aperture alignment.The second rigid slab 26a is fixed on limiting part 60a by a few cover screws and packing ring 50a.The representation completing before arm brace 14 is applicable to the combination storage shelf vibration insulator of storage shelf system existing and coming of new.Use is contained in the extra pin 59a of slip heelpiece 30a so that pillar 14 is fixed on slip heelpiece 30a.In this specific embodiment, cutting slip heelpiece 30a is to allow to approach the lower end of pillar.Storage shelf vibration insulator 20a install on the ground and and the erection bolt 54a of base nut 56a by embedding ground firmly fix.

In seismic events, limiting part 60a restriction earthquake vibration absorbs and the horizontal movement of dissipation structure 22a, substantially to make damping effect along unidirectional and be parallel to fixedly heelpiece 32a.Limiting part 60a also limits the vertical motion of storage shelf vibration insulator 20a.In seismic events, although limiting part 60a keeps fixing owing to being connected in fixedly heelpiece 32a, the slip heelpiece 30a that is connected in elastic parts 22a slips over by limiting part 60a and passage that fixedly heelpiece 32a produces.When seismic events finishes, the elasticity of elastic parts 22a makes storage shelf system get back to its about initial position help.

If elastic parts 22a lost efficacy, limiting part 60a will help at all directions stationary storage frame system.Contact between the limiting part 60a of combination and fixedly heelpiece 32a and slip heelpiece 30a is by any damage reducing storage shelf system.

Although limiting part 60a has limited vertical motion and in the motion of the higher horizontal dimension of storage shelf system flexibility, the compressibility of elastic parts 22a allows to occur some motions in these directions.Thereby extra vibration damping and isolation is provided in these directions, and improved the performance of storage shelf vibration insulator 20a.Limiting part 60a also avoids collision for the protection of storage shelf vibration insulator.

When seismic events is when for example earthquake occurs, measure ground motion also causes vibration at horizontal direction.The end of erection bolt 54a fixedly secures in its embedded concrete surface, and the base nut 56a on erection bolt 54a fixedly heelpiece 32a is fixed on ground.Mechanical constraint parts 60a is welded in fixedly heelpiece 32a and has the second rigid slab 26a that has connected elastic parts 22a, and in earthquake, limiting part 60a allows elastic parts 22a to vibrate together with ground with the second rigid slab 26a.These vibrations are delivered to the first rigid slab 24a and connected slip heelpiece 30a by elastic parts 22a.Pillar 14 is not fixed to ground but can be free to slide along with slip heelpiece 30a, pillar 14 by low frictional torque bearing material 34a and fixedly heelpiece 32a be connected to slip heelpiece 30a, elastic parts 22a responds this motion and stretches.This extensional motion has dissipated and has been delivered to some seismic energies of storage shelf system.Elastic parts 22a absorbs some oscillation crosswise, and helps storage shelf system and more seismic oscillation crosswise isolation.Therefore, storage shelf vibration insulator 20a reduced earthquake on storage shelf system with and storage shelf on the article that store or the impact of material.Some energy that are delivered to storage shelf system also by overcome shore supports assembly place frictional force so that pillar motion dissipate.When earthquake finishes, the elasticity of elastic parts 22a makes storage shelf system get back to its about initial position.

Select appropriate elastic body to make the elastic parts 22a of the storage shelf vibration insulator of its type that can be used for describing in Fig. 8 to Figure 17 must consider several factors, comprise the design load of storage shelf system and the target intrinsic frequency that will reach.Although any reducing of the intrinsic frequency of storage shelf system all will provide the protection of antiseismic event, target of the present invention is to reduce the intrinsic frequency of storage shelf system significantly to reduce the damage to storage shelf, and the product being stored in storage shelf can not fall.Preferably the intrinsic frequency of storage shelf system is reduced to below about 0.9Hz, or is reduced to ideally below about 0.5Hz.According to the expectation peak load of the target intrinsic frequency of wanting to reach and storage shelf system, can select to reach the storage shelf vibration insulator of these frequencies.By selecting to be used in the elastomeric material in elastic parts according to its static modulus and dynamic modulus or intensity, can calculate these parameters.

The static strength of elastomeric material can be measured by several coefficients, comprises compressive strength K _compressionwith shear strength K _shear.Compressive strength is measured as and makes the vertically required power of distance of elastic body (a for example rubber) deflection one, and its unit is pounds/inch.Shear strength K _shearbe measured as the size that makes the required power of specific tangential distance of rubber deflection one, its unit is pounds/inch.

Dynamic characteristic makes elastomeric material can be used for absorbing the energy in seismic events, and a kind of situation in dynamic characteristic is exerted all one's strength for these materials have and elasticity and the non-resilient composition of displacement out-phase, thereby allows to occur dissipation or " decay " of energy.The dynamic characteristic of elasticity assembly comprises damping intensity K ", represent the non-resilient intensity that reaction is " lag time " between displacement and the power that applied by material subsequently, also comprise elastic strength K ', represent the intensity with the displacement homophase of material.Damping intensity K " and elastic strength K ' be respectively that the viscous damping C that introduces in Fig. 7 and elastic strength K are for the concrete application of elastomeric material.Damping intensity K " and the unit of elastic strength K ' be all pounds/inch.The damping loss coefficient of specific rubber be its damping intensity divided by the ratio of its elastic strength,

L _dif＝K”/K’

Box dynamic tester is for to elastomeric material dynamic load, and measures the degree that the elastic reaction of the material that the physical characteristic due to material causes is attenuated.Rubber or other elastomeric materials should have and be greater than the damping loss coefficient that is approximately 0.1,

K”/K’＞0.1

Above-mentioned intensity parameter is also relevant with the elastomeric hardness of measuring in hardometer.The Determination of Hardness value of certain elasticity body is higher, and it is harder.

As mentioned above, because storage shelf system is low along the crossing direction flexibility of passageway direction ratio and passageway, must selection at least the elastic body of the intrinsic frequency of whole storage shelf Zhu system can at least reduced with the crossing direction in passageway.Calculate, for being about 40 in the lower design peak load ability that comprises three rows, two pillars of every row with the crossing direction in passageway of flexibility, the storage shelf system of 000lbs, for whole storage shelf system, the storage shelf vibration insulator system that total shear strength is approximately 1,600lbs/in will be reduced to about 0.6Hz with the intrinsic frequency of the crossing steering handle storage shelf in passageway.The pillar of the storage shelf system that definite permission is such moves about 5 inches from its initial position can provide enough vibration isolation.

To this by its 40, the load of 000lbs is distributed in the lower storage shelf system that comprises three rows, two pillars of every row with the crossing direction in passageway of flexibility has successfully carried out seismic test.Press the configuration shown in Fig. 8 and Fig. 9, between flexibility direction lower and that passageway is crossing, two pillars every row, two storage shelf vibration insulators have been installed.Six storage shelf vibration insulators all have the static shear intensity of about 270lbs/in, are total up to 1,600lbs/in.This storage shelf system is not subject to any damage, and load is not fallen from shelf yet.The pillar quantity of storage shelf system does not limit the quantity of operable storage shelf vibration insulator unit.If had living space, extra storage shelf vibration insulator can be installed between pillar to obtain suitable effect.

Determined that by intensity, to be that about 40 Determination of Hardness values (durometer), loss factor are that design peak load that elastic parts that about 0.3 butyl rubber (ASTM D2000 4AA415 A13 Z1) is made is suitable for each vertical framework reaches about 10, the storage shelf system of 000lbs.If be equipped with extra damping, it is about 20 that the design peak load that the elastic parts that the butyl rubber that is about 40 Determination of Hardness values by intensity is made can be used for each vertical framework reaches, the storage shelf system of 000lbs.Determined by intensity be about 60 Determination of Hardness values, loss factor be elastic parts that about 0.45 butyl rubber (ASTM D2000 4AA615 A13 Z1) is made be suitable for each vertical framework design peak load greatly about 10,000lbs to 20, the storage shelf system between 000lbs.Should carry out extra test to be identified for having the optimal properties of elastic parts of the different storage shelf designs of different designs load range.If used softer material to having surpassed the application of the design maximum load range of storage shelf system, should comprise extra damping in elastic parts.This can be by comprising deformable lead for retractable pencil or other equipment is realized in elastic parts.Other secondary (secondary) damping elements, for example hydraulic vibration absorber can add together with isolation damper.

For the motion of storage shelf system being limited in substantially to flexible the second lower horizontal dimension, only need the motion of restriction pillar.Figure 14 has shown the embodiment with Figure 12 and 13 similar storage shelf vibration insulator 20f, wherein the shore supports assembly of every pillar 14 by slide heelpiece 30f and fixedly heelpiece 32f form, every pillar 14 is connected in slip heelpiece 30f, and slip heelpiece 30f is positioned at fixedly on heelpiece 32f.Each fixedly the size of heelpiece 32f only on the pillar range of movement of estimating, extend.The same with the embodiment in Figure 12 and Figure 13, fixedly heelpiece 32f has been transformed into U-shaped mechanical constraint 60f, but in this example, constraint only limits to pillar.

Figure 15 has shown another variant, wherein the mechanical constraint 60g of storage shelf vibration insulator 20g folding groove that can slide therein to produce pillar 14 on slip heelpiece 30f.The vertical motion that this change has limited pillar 14 is to reduce in earthquake storage shelf system by the possibility of overturning.Some that provide groove in the mechanical constraint 60g of vibration isolation can be configured to allow pillar 14 at vertical direction are vertically moved.

Contrary with embodiment shown in Figure 14 and 15, Figure 16 has shown another embodiment storage shelf vibration insulator 20h, wherein the motion of a constrained vibration absorption and dissipation structure with by the movement limit of storage shelf system in the second lower horizontal dimension 10 of flexibility.In this embodiment, absorption of vibrations and dissipation structure flexibility lower be connected in the crossbeam 16 of storage shelf system with the crossing direction 10 in passageway.Earthquake vibration absorbs and dissipation structure comprises a pair of elastic parts 22h as the interface between storage shelf system and ground.In this embodiment, fixedly heelpiece 32h under the pillar 14 of storage shelf system and between extend.Two elastic parts 22h are connected in crossbeam 16 at link 38h place, the position that the position of link 38h welding should be installed along crossbeam 16 corresponding to elastic parts 22h.But in this embodiment, the first rigid slab 24h comprises the flange with groove, and a part of limiting part 60h can be arranged in this groove.The first rigid slab 24h has elastic body covering layer 62h to help to absorb the vertical shock of the relative limiting part 60h of the first rigid slab 24h in seismic events.Elastic body covering layer 62h can be any absorption of vibrations material, such as rubber etc.

The effect of limiting part 60h is that protection storage shelf vibration insulator is avoided side impact.In seismic events, limiting part 60h is limited in the horizontal movement of storage shelf vibration insulator 20h a horizontal direction as shown in direction arrow 10 substantially, its flexibility corresponding to storage shelf system lower with the crossing direction in passageway.Limiting part 60h also limits the vertical motion of storage shelf vibration insulator 20h substantially.Although limiting part has limited the horizontal movement perpendicular to direction arrow 10 substantially, in this direction, also have some spaces to transmit some extra dampings along passageway direction.Similarly, although limited the motion that storage shelf system makes progress, also have some spaces of storage shelf vibration insulator at vertical direction, it has transmitted some dampings at vertical direction.

Limiting part 60i avoids side impact for the protection of slide unit 70i.In seismic events, limiting part 60i is for the horizontal movement of slide unit 70i being limited in substantially to direction as shown in direction arrow 10 along a fixing horizontal direction of the concave of heelpiece 32i, its flexibility corresponding to storage shelf system lower with the crossing direction in passageway.Limiting part 60i also limits the vertical motion of storage shelf vibration insulator 20i substantially.In addition, also limit slippage parts 70i is along the transportable distance of direction shown in direction arrow 10 for limiting part 60i, and this has guaranteed that pillar 14 can not leave fixedly heelpiece 32i.

In seismic events, when pillar is when fixedly the concave upper surface of heelpiece 32i is moved, the energy that is delivered to storage shelf system is dissipated.This motion is equivalent to the elastic strength K shown in Fig. 7, and can be measured as and along fixing heelpiece 32i, move the potential energy of time institute's loss when storage shelf system.This intensity equivalent K _eqcan be expressed as equation form:

$K_{\mathrm{eq}}=\frac{h\left(x\right)\mathrm{mg}}{x^2}$

Wherein x is the horizontal range that storage shelf moves, and h (x) is the vertical distance that storage shelf moves, and m is the quality of storage shelf system, and g is gravity.Viscous damping C shown in Fig. 7 also can be measured as and overcome slide unit 70i and slip heelpiece 30i and the fixing required energy loss of frictional force between the contact surface of heelpiece 32i.

Although limiting part 60i has limited the motion perpendicular to direction arrow 10 substantially, in this direction, also have some spaces, it is transmitting some extra dampings along passageway direction.Similarly, although limited the motion that storage shelf system makes progress, also have some spaces of storage shelf system at vertical direction, it has transmitted some dampings at vertical direction.

Another mechanism that can be used as earthquake vibration absorption and dissipation mechanism is spring mechanism.Figure 23 has shown storage shelf vibration insulator 20l, and wherein earthquake vibration absorption and dissipation mechanism comprise the spring 80l that is connected in storage shelf system.Contrast Figure 23 and 24 the most easily understands, in this embodiment, crossbeam 16 be connected in storage shelf system flexibility lower with the two pillars 14 crossing direction in passageway.Spring 80l is installed on and is connected in the first plate 82l of crossbeam 16 and is connected between the second plate 84l of fixing heelpiece 32l.Limiting part 60l is welded in fixedly heelpiece 32l.

In seismic events, the horizontal movement of limiting part 60l restriction storage shelf vibration insulator 20l, substantially to make damping action along one direction and to be parallel to fixedly heelpiece 32l, limits the vertical motion of storage shelf vibration insulator 20l simultaneously.Spring 80l responds the motion of storage shelf system and stretches and compress.Be connected in element 86l and the 88l stretching that restraining spring 80l stands respectively and the degree of compression of the first and second plate 82l and 84l.By the elastic parts comprising as shown in Figure 21 and 22, can obtain extra damping.

When spring 80l stretches and compress, the energy that passes to storage shelf system in seismic events is dissipated.Elastic strength K shown in Fig. 7 is the physical property of this spring, according to concrete application, can select suitable spring.Can select the geometry of spring so that appropriate spring intensity K to be provided.Viscous damping C shown in Fig. 7 is measured as the frictional force that storage shelf system is moved and must overcome in such spring system.The pillar 14 of mobile storage shelf system needs to pass in seismic events some energy of storage shelf system, to overcome slip heelpiece 30l and the fixing frictional force on the contact surface of heelpiece 32l.

As shown in figure 25, in storage shelf vibration insulator also useable linear bearing as absorption of vibrations and dissipation structure.In this embodiment, storage shelf pillar 14 is welded in plate 90m, across the track 92m of two pillars, is connected in plate 90m.Track 92m is through a set of housing 94m that comprises linear bearing 96m.Housing 94m is connected in fixedly heelpiece 32m.In this embodiment, absorption of vibrations and dissipation structure are also simultaneously as shore supports assembly.The storage shelf framework that housing 94 and linear bearing 96 supports are suspended from the ground and the total weight of pillar 14.Linear bearing 96 and housing 94 can be from any manufacturers, for example GGB Bearing Technology.Linear bearing 96 can be made by composition polymer, maybe can comprise that rubber or elastic parts are to provide extra compliance (compliance) and damping.In seismic events, linear bearing 96m allow storage shelf system flexibility lower with crossing direction 10 motions in passageway.By adjusting the installation of linear bearing 96m, can change the required power of mobile storage shelf system.
