The specific embodiment
With reference to the accompanying drawings, a plurality of embodiment and shown in and described picture in, Reference numeral be used to refer to the generation identical or corresponding parts.In a particular embodiment, the variation of corresponding component is indicated by the additional subscript letter.The variation of the assembly that shows among the figure subsequently but do not describe is for corresponding to aforesaid specific embodiment, discusses in the excursion of their forms or function.The general variation that should understand among the embodiment can be exchanged not deviating under the prerequisite of the present invention.
How to design and make according to structure, all there is intrinsic frequency in each storage shelf system.The intrinsic frequency of storage shelf system is also relevant with its intensity, and provides in seismic events, the information how the storage shelf system will react.Typically, the storage shelf system is flexible higher (being that it has lower intrinsic frequency) of (down-aisle) direction along the passageway, intersecting the direction flexibility lower (being that it has higher intrinsic frequency) of (cross-aisle) with the passageway.Definite, the representative vertical structure storage shelf that Ridg-U-Rak company produces is approximately 0.9Hz along the intrinsic frequency of passageway direction, and the intrinsic frequency of the direction that intersects with the passageway is approximately 1.6Hz.Estimate that there is similar design in most storage shelf system, and similarly higher in the direction rigidity that intersects with the passageway.During seismic events, storage shelf vibration to be offsetting the stress that is delivered to storage shelf because of the earth motion, so storage shelf will respond earthquake and moves.The vibration that is delivered to the storage shelf system improves according to earthquake intensity, but when the vibration frequency from seismic events surpasses 1.5Hz, the storage shelf system will typically experience destruction.Because typical storage shelf system has had the intrinsic frequency of 1.6Hz in the direction that intersects with the passageway, not too strong earthquake will destroy them.
The intrinsic frequency that reduces the storage shelf system will reduce the influence of seismic events.For reaching this purpose, must give the storage shelf system extra flexibility, and not sacrifice its stability and intensity.This can be by not changing the storage shelf system structure but change the mode that storage shelf is connected in ground and reach.The storage shelf vibration insulator that is connected in ground and storage shelf is as the interface between ground and storage shelf, and therefore storage shelf is connected in the storage shelf vibration insulator in one or another kind of mode now, rather than is directly connected in ground.
Referring to figs. 1 to Fig. 4, storage shelf vibration insulator 20a comprises the first rigid slab 22a, second rigid slab 24a and the elastic parts.In Fig. 1 was extremely embodiment illustrated in fig. 4, this elastic parts comprised an elastomeric element 26a who extends between rigid slab 22a and 24a.This elastic parts is operably connected to first and second rigid slab 22a and the 24a, so that in seismic events, the first and second rigid slab 22a and 24a keep and being connected of elastic parts, and while first and second rigid slab 22a and 24a can move in plane parallel to each other substantially.This elastomeric element is by absorbing in seismic events and the material of dissipation the earth kinergety is made.For example, elastomeric element 26a can be by polyisoprene, polyisoprene mixture (polyisoprene blend), butyl rubber, silicon or other high damping elastomers, and for example those that produced by Corry Rubber Corporation of Corry (PA) are made.Elastomeric element 26a can also be made of following any material that can stand the load of storage shelf system and have a desired intensity feature.
Rigid slab 22a and 24a can make as the suffered load of the parts of storage shelf vibration insulator 20a and any metal sheet of power by standing it.In one embodiment, the first and second rigid slab 22a and 24a be by the steel plate punching press, and the first rigid slab 22a is stamped into has semicircular plate space 27a at two ends.Similarly, the two ends of elastomeric element 26a also comprise semicircular plate space 29a.
The relative thickness of the first rigid slab 22a, the second rigid slab 24a and elastomeric element 26a can be dependent on the specific requirement of the application of storage shelf vibration insulator 20a.For example, 1/8 inch first thick rigid slab 22a can corresponding 1/2 inch thick elastomeric element 26a and 3/8 inch second thick rigid slab 26a.Should understand other thickness also can, also in the scope that the present invention conceived.
Cohesive material be between the first rigid slab 22a and the elastomeric element 26a and the elastomeric element 26a and the second rigid slab 24a between.Cohesive material forms firm combination is enough to prevent that the first and second rigid slab 22a and 24a from contacting with elastomeric element 26a forfeiture, even when storage shelf vibration insulator 20a is subjected to very big external force.Appropriate adhesive comprises all to be made by Lord Corporation

The perhaps stickum of other firm combining that are adapted at providing such between the rigid slab of elastic body and for example metal.
Comparison diagram 1 and the easiest understanding of Fig. 2, when the first rigid slab 22a viscosity was incorporated into elastomeric element 26a, the semicircular plate space 29a of the semicircular plate space 27a of the first rigid slab 22a and elastomeric element 26a roughly alignd.In conjunction with semicircular plate space 27a and semicircular plate space 29a produce bolt space 25a at the two ends of storage shelf vibration insulator 20a.Top view by contrasting storage shelf vibration insulator 20a shown in Figure 3 and its lateral view and partial cross section figure shown in Figure 4 can further understand each self-structuring of bolt space 25a.
Storage shelf vibration insulator 20a also comprises a pair of erection bolt 28a, a pair of basic nut 30, when basic nut 30 is installed on the erection bolt 28a, its contiguous second rigid slab 24a, also comprise a pair of rectangular gasket 32 and a pair of washer nut 34, when washer nut 34 is installed on the erection bolt 28a, the upper side of its contiguous packing ring 32.Washer nut 34 remains on packing ring 32 against the position of the first rigid slab 22a.The bottom of erection bolt 28a should form in such a way, and promptly they are firmly fixed by flooring material, utilizes storage shelf vibration insulator 20a that the storage shelf system has been installed on it.Erection bolt 28a shown in Fig. 1 to 4 is configured to be installed on and firmly fixed by concrete mats.In this embodiment, each the erection bolt 28a not end of tapping inwardly attenuates towards the center of erection bolt gradually, removes the resistance of concrete surface to increase erection bolt.The part of erection bolt 28a tapping is installed the hole 36a by the second rigid slab 24a.
Erection bolt 28a does not directly contact the first rigid slab 22a or elastomeric element 26a, but extends to packing ring 32 from the second rigid slab 24a by bolt space 25a.Bolt space 25a is general enough big, to prevent the motion of in seismic events erection bolt 28a severe interference first rigid slab 22a and/or elastomeric element 26a.Bolt space 25a is general, and enough big also the permission uses spanner or other to be used to tighten or unclamp the instrument of basic nut 30.
Storage shelf vibration insulator 20a is transported to and will uses before its installation site of storage shelf system, and rigid slab 22a and 24a can be assembled together.The storage shelf vibration insulator that the present invention is not only limited to step manufacturing or makes with any special material.But, the other materials of the elastomeric element 26a of polyisoprene, polyisoprene mixture or butyl rubber or storage shelf vibration insulator 20a can be by mixing a collection of raw material manufacturing, in mode well known to those skilled in the art, require to make the rubber that has physical characteristic (for example different types of intensity and damping) and expect to be used for storage shelf vibration insulator 20a.When mixing this batch raw material, it can remove from blender, drops into grinder, and mixing and film-making become to be fit to insert the size in the injection moulding machine.Cooling of this batch raw material and check guarantee that it can be loaded in the injection moulding machine after its intensity and damping characteristic with requirement.Packing ring 32 can be the metal stamping goods by zinc phosphate (zinc phosphate) or blasting treatment.
When cohesive material is put between the first rigid slab 22a and the elastomeric element 26a and the elastomeric element 26a and the second rigid slab 24a between the time, can apply and make by Lord Corporation Be thereafter

Metal washer 32 can be packed in the mould in the injection moulding machine.Then, the rubber of this machine of having packed into can be injected into mould, and the sandwich structure of plate 22a that obtains and 24a and rubber elastomer 26a can cure then.Typically, this assembly removes and processed shearing from this mould subsequently.
The lower end of storage shelf pillar 38 is welded in the first rigid slab 22a at solder joint 31a place.Elastic layer 26a and the thermal stress that produces can stand that pillar is welded on the first rigid slab 22a to the adhesive that elastic layer 26a is bonded to the first rigid slab 22a and the second rigid slab 24a time.Found that such thermal stress resistance is present in polyisoprene, polyisoprene mixture or the butyl rubber that is used for forming elastic layer 26a.Also find compression, bump and lateral stress that these materials run in the time of can resisting that pillar is positioned over and be connected in the first rigid slab 22a subsequently.
The end of thread of erection bolt 28a passes the hole 36a of second rigid slab or plate 24a, and basic nut 30 tightens so that the second rigid slab 24a is fixed in ground tightly against the second rigid slab 24a, and the lower end of erection bolt 28a embeds in the ground.Rectangular gasket 32 is positioned on the erection bolt 28a top, and washer nut 34 is tightened against the upper end of packing ring 32.This causes packing ring 32 to apply downward power to the first rigid slab 22a, elastomeric element 26a and the second rigid slab 24a.The storage shelf system be stored in storage shelf on and the article that are connected by pillar 38 or the weight of material load further for storage shelf vibration insulator 20a.
Referring to figs. 1 to Fig. 4, when earthquake incident when for example earthquake takes place, the earth motion also produces horizontal vibration.This motion has also produced the acceleration that the storage shelf system attempts to mate.If the pillar of storage shelf is fixed in ground, the element of construction of the badly damaged storage shelf of this acceleration possibility system.In addition, the article that are stored on the storage shelf shelf may fall shelf.Storage shelf vibration insulator 20a can absorb and the dissipation seismic events in some power of standing of storage shelf system.Because the lower end of erection bolt 28a securely is fixed in the embedded concrete surface of bolt, and basic nut 30 is fixed in ground with the second rigid slab 24a, the relative ground of second rigid slab 24a oscillation crosswise in the earthquake.The acceleration that this transverse movement causes transmits by storage shelf vibration insulator 20a, and causes that the storage shelf system moves with elastic parts.The motion of this elastic parts, or compliance have improved the overall flexibility of storage shelf system and the earthquake that is used to dissipate is delivered to the energy of storage shelf system.In addition, the elastic parts the earth motion that also decayed is delivered to the vibration of storage shelf system in the earthquake.Storage shelf vibration insulator 20a has reduced the intrinsic frequency of storage shelf system, so the storage shelf system can stand seismic events better.
Though any protection that reduces all will provide antiseismic incident of the intrinsic frequency of storage shelf system, target of the present invention are to reduce the intrinsic frequency of storage shelf system reducing the damage to storage shelf, and the product that is stored on the storage shelf can not fall.Preferably the intrinsic frequency with the 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 target intrinsic frequency of desiring to reach and storage shelf system, can select to reach the storage shelf vibration insulator of these frequencies.By according to its static modulus and dynamic modulus, or intensity selects to be used in the elastomeric material in the elastic parts, can calculate these parameters.
The static strength of elastomeric material can be measured by several coefficients, comprises compressive strength K CompressionWith shear strength K ShearCompressive strength is measured as and makes the vertically required power of distance of elastic body (for example rubber) deflection one, and its unit is pounds/inch, and shear strength K ShearBe measured as the size that makes the required power of a rubber deflection one tangential distance, its unit is pounds/inch.
Dynamic characteristic makes elastomeric material can be used for absorbing energy in the seismic events, and a kind of situation in the dynamic characteristic is exerted all one's strength for these materials have and the elasticity and the non-resilient composition of displacement out-phase, thereby allows to take place dissipation or " decay " of energy.The dynamic characteristic of elasticity assembly comprises damping intensity K ", expression reaction also comprises elastic strength K ' for the non-resilient intensity of " lag time " between displacement and the power that applied by material subsequently, the intensity of expression and the displacement homophase of material.Damping intensity K " and the unit of elastic strength K ' all be pounds/inch.The damping loss coefficient of specific rubber is the ratio of its damping intensity divided by its elastic strength,
L dif＝K”/K’
The dynamic test machine is used for to the elastomeric material dynamic load, and measures the degree that the elastic reaction of the material that the physical characteristic owing to material causes is attenuated.Rubber or other elastomeric materials should have greater than the damping loss coefficient that is approximately 0.1, promptly
K”/K’＞0.1
Above-mentioned intensity parameter is also relevant with the elastomeric hardness of measuring in hardometer.The hardness measured value of certain elasticity body is high more, and it is hard more.
Polyisoprene, polyisoprene mixture, silicon and butyl rubber belong to fixed to be satisfied these general conditions and is suitable for the material of elastomeric element.But should be appreciated that the other materials that meets these requirements substantially also is fit to and thinks within the scope of the invention.
The structural change that should also be clear that first or second rigid slab or elastomeric element also is possible, also belongs to design scope of the present invention.For example, Fig. 5 has shown storage shelf vibration insulator 20b, and wherein elastic parts comprises the elastomeric element 26b with top depression surface 39 and flaring (booted edge) 40.During assembling storage shelf vibration insulator 20b, the size of the first rigid slab 22b can be installed in the flaring 40 it, and attaches to the top depression surface 39 of the first rigid slab 22b.Therefore, the size of the first type surface area of coverage of the first rigid slab 22b area of coverage that should be slightly less than elastomeric element 26b is contained in the flaring 40 to allow.The vertical size of the semicircular plate space 29b of elastomeric element 26b also must increase, to allow that the semicircular plate space 27b of the first rigid slab 22b is surrounded by flaring 40 when assembling.
In certain embodiments, the semicircular plate space of first rigid slab and/or elastomeric element can be replaced by other suitable space structures, and relative motion elastomeric element in seismic events of allowing between bolt and the plate can absorb and the bolt space of dissipation kinergety thereby this space structures produces.The semicircular plate space also produces allows and uses spanner to regulate basic nut.Fig. 6 has shown storage shelf vibration insulator 20c, and wherein the semicircular plate space shown in the embodiment of front is replaced by the bolt accommodation hole 42 that increases.Bolt accommodation hole 42 combines with the semicircular plate space 29c of elastomeric element 26c forming bolt space 25c, the size of bolt space 25c much larger than the thickness of single erection bolt 28c to allow the motion of bolt 28c.Replace semicircular plate space 29c though Fig. 6 has only shown with bolt accommodation hole 42, should be appreciated that in certain embodiments, semicircular plate space 29c can also be replaced by similar cellular type contained structure.Such contained structure can also add in the assembling bolt space of first rigid slab and elastomeric element.
Though with further being connected to second rigid slab and having first rigid slab and the elastic parts demonstration of the concrete surface that is connected in the rectangular gasket that prolongs bolt and described the present invention, but should be appreciated that common and nonessential rectangular gasket and/or other clamping devices of comprising, between first rigid slab, elastomeric element and second rigid slab, use adhesive just can obtain enough structural stabilities usually separately.Fig. 7 has shown the storage shelf vibration insulator 20d after the assembling, and wherein erection bolt 28d does not extend on the first rigid slab 22d, and does not wherein have rectangular gasket or other clamping devices.The exploded view of storage shelf vibration insulator 20d shown in Figure 7 is presented among Fig. 8.
Storage shelf vibration insulator 20d relies on the adhesive that puts between the first rigid slab 22d and the elastomeric element (being independent elastomeric element 26d in the present embodiment) to obtain to install and structural stability.Bolt 28d only needs fully to extend on the second rigid slab 24d allowing geared screw 30, thereby the second rigid slab 24d firmly is connected to ground.Comprised the semicircular plate space 27d of the first rigid slab 22d and the semicircular plate space 29d of elastomeric element 26d and allowed the bolt space 25d that uses spanner or other instruments to adjust basic nut 30 to reserve.
In application more of the present invention, may pillar be welded to first rigid slab in the assembling place, or may be opposite, preferably before assembling, pillar is connected to first rigid slab.Fig. 9 has shown the storage shelf vibration insulator 20e after the assembling, and itself and storage shelf vibration insulator 20d shown in Figure 7 are similar.But the exploded view Figure 10 of the storage shelf vibration insulator 20e shown in Fig. 9 has shown pillar 38, and it has been welded in the first rigid slab 22e, is welded to connect parts 44e to form before storage shelf vibration insulator 20e assembling.
Though the present invention's demonstration also is described as the storage shelf pillar of permanent weld in first rigid slab of storage shelf vibration insulator, but should be appreciated that otherwise some embodiments of the present invention can allow to remove pillar from the storage shelf vibration insulator that has assembled, and need not remove first rigid slab, elastomeric element and second rigid slab that viscosity connects.Figure 11 has shown the storage shelf vibration insulator 20f that has assembled, and it has the independently frame substrate 46f that is welded in storage shelf pillar 38, is welded to connect parts 44f with formation.The easiest understanding of exploded view of the storage shelf vibration insulator among contrast Figure 11 and Figure 12, frame substrate 46f comprises pin-and-hole 48 that all runs through frame substrate 46f and the bolt accommodation hole 50 that enlarges.
The first rigid slab 22f comprises a plurality of from the upwardly extending pin 52 of the first rigid slab 22f upper surface.Otherwise sell 52 compressible assemblings and/or welding or be connected in the first rigid slab 22f.Contrast Figure 11 and the easiest understanding of Figure 12, when substrate 46f is positioned on the first rigid slab 22f, aim at the pin-and-holes 48 of each pin 52, when assembling storage shelf vibration insulator 20f with engagement frame substrate 46f, each pin 52 inserts and extends at the upper surface of substrate 46f, as shown in figure 11.
When storage shelf vibration insulator 20f was installed, pin 52 kept the alignment relative of the first rigid slab 22f and frame substrate 46f.Though the first rigid slab 22f viscosity is connected in the elastomeric element 26f of elastic parts (its viscosity be connected in the second rigid slab 24f) successively, in the embodiment of this demonstration, does not have the first rigid slab 22f to be connected with the viscosity of frame substrate 46f.This allows to install the frame that is supported by pillar 38 back and can remove from storage shelf vibration insulator 20f, and does not need to cut away or the destructive pillar 38 of removing from the first rigid slab 22f.
The bolt accommodation hole 50 of substrate 46f is extended to allow the insertion of erection bolt 28f, and bolt 28f is connected in rectangular gasket 32 by washer nut 34.As semicircular plate space 27f and semicircular plate space 29f, bolt accommodation hole 50 helps the whole bolt of definition space 25f, and in seismic events, bolt space 25f allows moving freely of erection bolt 28f and passes through the energy dissipation of elastomeric element 26f.Though frame substrate 46f shows and is described as having bolt accommodation hole 50, should be appreciated that in the scope of the present invention's design and also can use the semicircle space of the semicircular plate space 27f that is similar to the first rigid slab 22f and the semicircular plate space 29f of elastomeric element 26f.
In the time of on pillar 38 being installed in storage shelf vibration insulator 20f, rectangular gasket 32 prevents the separation of frame substrate 46f from the first rigid slab 22f, therefore prevents that pillar 38 is welded to connect parts 44f and upwards leaves storage shelf vibration insulator 20f.In seismic events, as erection bolt 28f during owing to the motion campaign of the earth, rectangular gasket 32 is moved with erection bolt 28f.Can be by unclamping and removing washer nut 34 and remove packing ring 32, to allow by going up hoisting frame substrate 46f from the first rigid slab 22f and not cutting or destroy storage shelf vibration insulator 20f ground and remove pillar 38.
Allow that other structures that first rigid slab is alignd with the frame substrate also are possible.With reference to Figure 13, storage shelf vibration insulator 20g is shown as has the key 54 that extends from frame substrate 46g downwards.The easiest understanding of exploded view of contrast Figure 13 and Figure 14, key 54 can be bent downwardly fragment to form independently key 54 then by forming for each key 54 cuts two parallel cuts in frame substrate 46g between every pair of otch.Keyway 56 cuts in the first rigid slab 22g, its size mesh key 54, and when alignment frame substrate 46g places the first rigid slab 22g to go up the alignment frame substrate 46g and the first rigid slab 22g, and do not limit frame substrate 46g upward to motion.Therefore, when having removed washer nut 34 and rectangular gasket 32, pillar 38 and frame substrate 46g that key 54 and keyway 56 allow common formation to be welded to connect parts 44g remove by upwards promoting from the first rigid slab 22g, and need not cut or destroy storage shelf vibration insulator 20g.
Should also be clear that some embodiment allow removal and arm brace and/or are welded to connect parts, and do not use packing ring and washer nut.For example Figure 15 has shown the storage shelf vibration insulator 20h of assembling, Figure 16 has shown its exploded view, this storage shelf vibration insulator 20h comprises and is welded to connect parts 44h, wherein frame substrate 46h comprises the substrate aperture 58h that is positioned at two angles, and it aligns with the rigidity plate hole 60h of the first rigid slab 22h during assembling.The size of substrate aperture 58h and rigidity plate hole 60h can be held plate bolt 62h, and plate bolt 62h provides the connection between the frame substrate 46h and the first rigid slab 22h, and can tighten to crab bolt 64h.
Plate bolt 62h and crab bolt 64h allow frame substrate 46h to remove from the first rigid slab 22h, and need not cut or destroy storage shelf vibration insulator 20h.In this embodiment, described elastic parts comprises single elastomeric element 26h.Being connected between the first rigid slab 22h and elastomeric element 26h and elastomeric element 26h and the second rigid slab 24h relies on therebetween adhesive.Erection bolt 28h and basic nut 30 are positioned at two jiaos of the second rigid slab 24h.Elastomeric element 26h comprises that four groove 66h are to hold spanner or the similar tool that is used to adjust basic nut 30 and crab bolt 64h.
In certain embodiments, the use of screwed part can be eliminated necessity of using nut, and further is beneficial to from storage shelf vibration insulator dismounting pillar and frame substrate.Figure 17 has shown the storage shelf vibration insulator 20i of assembling, and wherein the first rigid slab 22i comprises the rigidity plate hole 60i of internal thread, relatively the easiest understanding of exploded view of the storage shelf vibration insulator 20i among Figure 17 and Figure 18.When assembling storage shelf vibration insulator 20i, have externally threaded plate bolt 62i and run through the internal thread of the substrate aperture 58i of frame substrate 46i, thereby frame substrate 46i firmly is connected in the first rigid slab 60i with meshing positive plate hole 60i.The number of turns that the internal thread of rigidity plate hole 60i generally has sufficient amount need not extra hardware with abundant engaging plate screw 62i, installs and removes thereby further simplify.When the first rigid slab 60i is constructed by 1/4 inch thick panel material, there is the number of turns of sufficient amount usually.It is minimum that such size generally can also allow the size of plate bolt 62i to drop in the first rigid slab 60i, hidden the external screw thread of screw 62i in the first rigid slab 60i fully.
The variation that is installed to ground also within the scope of the invention.Below with reference to accompanying drawing several in many may the variation will be described.Figure 19 and 20 has shown assembling drawing and the exploded view that is mounted to the storage shelf vibration insulator 20j on ground with j shape bolt 68.J shape bolt 68 can be cast (cast) correct position and shape in concrete and hook concrete, perhaps can hook other following structures of ground level of the second rigid slab 24j.J shape bolt 68 comprise can through hole 36j the end of thread, thereby to mesh basic nut 30j storage shelf vibration insulator 20j firmly is connected in ground.The groove 66j of elastomeric element 26j allows to hold and is used for spanner or other instruments that the relative second rigid slab 24j tightens j shape hook.
Figure 21 and 22 has shown assembling drawing and the exploded view of storage shelf vibration insulator 20k, storage shelf vibration insulator 20k is installed on ground by erection bolt 28k, erection bolt 28k has screw thread and inserts the hole 36k of the second rigid slab 24k to allow external screw thread, thereby produces internal thread in the ground of supporting the second rigid slab 24k or terrestrial components (not shown).The groove 66k of elastomeric element 26j allows to hold and is used for spanner or other instruments that the relative second rigid slab 24k tightens erection bolt 28k, so that storage shelf vibration insulator 20k is firmly secured to ground.
The variation that also should further understand the cross-sectional geometry of rigid slab and elastomeric element or parts also belongs to scope of the present invention.For example, Figure 23 has shown the sectional view of storage shelf vibration insulator 201, and it has the elastic parts that comprises elastomeric element 261, and elastomeric element 261 has the thickness of increase.For comparison purposes, elastomeric element 261 relative first rigid slab 221 and second rigid slab 241 show increased cross-section thickness.The thickness of shear strength and elastomeric element 261 is inversely proportional to.Though compressive strength not with the thickness linear correlation of elastomeric element 261, the shear strength of elastomeric element 261 and reducing of compressive strength are allowed in the increase of the thickness of elastomeric element 261 as shown in the figure, under this situation about reducing of expectation.
In some applications, may expect to reduce shear strength and do not cause significantly reducing of compressed thickness.Figure 24 has shown the storage shelf vibration insulator 20m with elastic parts, and two middle rigid slab 70m are between thin slice elastic layer 26m, and the middle rigid slab 70m of combination and thin slice elastic layer 26m are between the first rigid slab 22m and the second rigid slab 24m.Appropriate cohesive material is bonded to its adjacent thin slice elastic layer 26m with each rigid slab 22m, 24m or 70m.
Suppose each thickness among three the elastic layer 26m that separate of elastic parts of the storage shelf vibration insulator 20m among Figure 24 be the single elastic layer 201 among Figure 23 thickness 1/3rd.Because total shear strength is inversely proportional to total combination thickness of the elastic layer 26m that separates, the total shear strength of the storage shelf vibration insulator 20m among Figure 24 roughly equates with total shear strength of storage shelf vibration insulator 201 among Figure 23.But as mentioned above, the gross thickness of compressive strength and elastic layer 26m is not a linear correlation.The elastic layer 26m that separates and place the intensity of storage shelf vibration insulator 20m on compression direction that therebetween middle rigid slab 70m causes Figure 24 almost than storage shelf vibration insulator 201 high index of Figure 23 times.
Figure 25 has shown the storage shelf vibration insulator 20n with the elastic parts that comprises a plurality of thin slice elastic layer 26n, and Figure 26 has shown its exploded view.With reference to Figure 25 and 26, intermediate plate 70n and fixedly positioning with adhesive between elastic layer 26n.Can be contemplated that singly between elastic layer 26n and the first rigid slab 22n, intermediate plate 70n, the second rigid slab 24n and use the i.e. enough generation appropriate combinations therebetween of adhesive, though also can add as shown in Figure 1 packing ring (for example rectangular gasket 32) and extending bolt 28n, or other so extra clamping devices.
Align with semicircular plate space 29n and semicircular plate space 27n in the intermediate plate space 71 that is positioned at each end of intermediate plate 70n, to form the bolt space 25n that allows near basic nut 30.The embodiment of isolator 20n comprises two about 1/2 " thick elastic layer 26n; elastic layer 26n is by one about 1/16 " thick intermediate plate 70n separates, further be contemplated that the elastomeric element of other quantity and relative thickness and intermediate plate also can, also within the scope of the invention.

The embodiment of the storage shelf vibration insulator that shows and describe is configured to allow crossbeam 90o to remove from storage shelf vibration insulator 20o.Should be appreciated that, the pillar of the storage shelf system that the storage shelf vibration insulator is connected in that in previous embodiment, shows and various other apparatus and method on ground, can also the storage shelf vibration insulator be connected in crossbeam and ground with additive method.
Though storage shelf vibration insulator 20o can be positioned at along any position of the length of crossbeam 90o, if only use a storage shelf vibration insulator 20o between pair of posts 38, storage shelf vibration insulator 20o is preferably located in apart from each pillar equidistant.
The structural change that should also be clear that vibration insulator also is possible, and it is also in design scope of the present invention.For example, though the storage shelf vibration insulator system that Figure 27 shows has only a storage shelf vibration insulator 20o who is connected in crossbeam 90o, should be appreciated that crossbeam can connect a plurality of storage shelf vibration insulators.Figure 29 has shown storage shelf vibration insulator according to another embodiment of the invention, and wherein two storage shelf vibration insulator 20p are connected in crossbeam 90p.Shown in the embodiment of Figure 27, storage shelf vibration insulator 20p has the link 46p of response, and it is positioned at the position of storage shelf vibration insulator 20p along crossbeam 90p place.Embodiment as described previously should be appreciated that various other apparatus and method of pillar of the storage shelf system that the storage shelf vibration insulator is connected in that shows in previous embodiment, can also the storage shelf vibration insulator be connected in crossbeam with additive method.
Figure 30 has shown storage shelf vibration insulator 20q, and it has the elastic parts with a plurality of thin slice elastic layer 26q, and single storage shelf vibration insulator 20q is connected in crossbeam 90q.Intermediate plate 70q and fixedly positioning with adhesive between elastic layer 26q.Can be contemplated that and singly between elastic layer 26q and the first rigid slab 22q, intermediate plate 70q and the second rigid slab 24q, use adhesive promptly enough to produce appropriate combination, though also can add packing ring, rectangular gasket (Fig. 1 for example, Figure 32) and extending bolt (Fig. 1, Figure 28 a), or other so extra clamping devices.
The embodiment of isolator 20q will comprise two about 1/2 " thick elastic layer 26q; elastic layer 26q is by one about 1/16 " thick intermediate plate 70q separates, further be contemplated that the elastomeric element of other quantity and relative thickness and intermediate plate also can, also within the scope of the invention.Storage shelf vibration insulator 20q is similar to described in Figure 28 to the connection of crossbeam 90q.Crossbeam 90q comprises link 46q, and its welding position will be along the installation site of crossbeam 90q corresponding to storage shelf vibration insulator 20q.Should be appreciated that this embodiment may be connected in the storage shelf system with the mode that is similar to any other embodiment that discloses herein.
Though the storage shelf vibration insulator system that Figure 30 shows only has a storage shelf vibration insulator 20q who is connected in crossbeam 90q, should be appreciated that crossbeam can connect a plurality of storage shelf vibration insulators.Figure 31 has shown that two storage shelf vibration insulator 20r are connected in crossbeam 90r, and storage shelf vibration insulator 20r comprises the elastic parts with a plurality of thin slice elastic layer 26r.
Should also be clear that the low friction heelpiece 94o-94r shown in Figure 27-31 needs not to be separation for each pillar 38.Figure 32 has shown the storage shelf vibration insulator system with two storage shelf vibration insulator 20s, and storage shelf vibration insulator 20s comprises and has a plurality of elastic parts that are connected in the thin slice elastic layer 26s of crossbeam 90s.Storage shelf vibration insulator 20s is connected on pillar 38 times and passes the fixedly heelpiece 94s that pillar 38 extends.The pillar 38 of storage shelf system is welded in the slip heelpiece 92s that is positioned on the fixing heelpiece 94s.Fixedly heelpiece 94s self is connected in ground by storage shelf vibration insulator 20s.The soffit of heelpiece 92s and/or fixedly the upper surface of heelpiece 94s can have the material that one deck has low-friction coefficient.Fixedly heelpiece 94s is of a size of and can covers that storage shelf can mobile zone in the seismic events.Should be appreciated that this monolithic fixedly heelpiece 94s can be applicable to pillar 38 and need in any variant of fixing heelpiece.
Should also be clear that among Figure 27-32 that the slip heelpiece 94o-94s that describes and show can be used in allows in the seismic activity or equivalent structure that the relative storage shelf vibration insulator of jury strut 38 system slides, and for example bearing, wheel, caster etc. replace or additional.
In certain embodiments, the variation of the cross-sectional geometry of the elastomeric element of rigid slab and elastic parts or parts can be used for controlling the stability of storage shelf vibration insulator.Figure 33 has shown storage shelf vibration insulator 20t, the second rigid slab 24t that it has the first crooked rigid slab 22t and has curved upper surface 74t.Elastomeric element 26t and is bonded to first and second rigid slab 22t and the 24t with adhesive between the crooked first rigid slab 22t and the second rigid slab 24t.The shape of elastomeric element 26t also is crooked, with when the power that contains horizontal or cross component is applied to the first and/or second rigid slab 22t and 24t, can apply compressed component to elastomeric element 26t by first rigid slab 22t of bending and/or the curved upper surface 74t of the second rigid slab 24t.Absorb and such power that is applied in that dissipates as the 26t of elastomeric element, curved shape is easy to make the stable and vertical position of storage shelf vibration insulator 20t shown in getting back to.In the seismic events, the concrete shape of rigid slab 22t and 24t and elastic parts allows to use compressed component to improve resistance to overturning like this.
Because the first rigid slab 22t and second rigid slab 24t edge are horizontal or lateral is crooked, shear strength K ShearIncrease along same direction.Storage shelf vibration insulator 20t among Figure 33 only increases K along an axle in hope like this Shear, and do not produce such increase and do not change the reduced overall intensity K of isolator 20t at vertical axle (for example along fore-and-aft direction) CompressionIn time, be particularly useful.Effectively, storage shelf vibration insulator 20t works in a horizontal direction basically, and it should be comprised in the storage shelf system to utilize such effect.

Figure 36 has shown the storage shelf vibration insulator 20u that comprises elastic parts, and storage shelf vibration insulator 20u has a plurality of planes of compressed component with enhanced stability that are used to operate.The first rigid slab 22u comprises contact surface 76u, first side contacts surface 78u and second side contacts surface 80u.The second rigid slab 24u comprises locating surface 82u, the first side locating surface 84u and the second side locating surface 86u.Elastomeric element 26u is positioned between the first and second rigid slab 22u and the 24u, and combines with each viscosity among surperficial 76u, 78u, 80u, 82u, 84u, the 86u.
When the last locating surface 82u of the last contact surface 76u of the first rigid slab 22u by bending and/or the second rigid slab 24u when elastomeric element 26u applies compressed component, downwards and/or the compressed component that makes progress can be absorbed by elastomeric element 26u or dissipate.If the first or second side locating surface 84u or the 86u of first or second side contacts of first rigid slab 22u surface 78u or the 80u or the second rigid slab 24u apply cross stream component, when elastomeric element 26u absorbs and dissipate the power that is applied in like this, to be easy to cause that with contacting of side surface 78u, 80u, 84u and 86u elastomeric element 26u makes the stable and vertical position of storage shelf vibration insulator 20u shown in getting back to, thereby in seismic events, utilize the compressed component that laterally applies to improve resistance to overturning.
Elastomeric element 26u has also improved along the shear strength Kshear of horizontal or lateral with contacting of 80u and the first and second side locating surface 84u or 86u with first and second side contacts surface 78u.Like this, storage shelf vibration insulator 20u also allows only to increase K along an axle Shear, and do not producing such increase along vertical axle (for example along fore-and-aft direction) and do not changing the reduced overall intensity K of isolator 20u CompressionEffectively, similar with the storage shelf vibration insulator shown in Figure 36, storage shelf vibration insulator 20u works in a horizontal direction basically, and it should be comprised in the storage shelf system to utilize such effect.
