Between be additionally provided with the backing plate 323 having a negative impact for avoiding the interphase interaction of single steel plate, the thickness gauge of backing plate 323
The very little thickness with steel plate 321 is identical, but sectional dimension is less than the size of steel plate 321 so that pad sets the multi-disc after backing plate 323
Steel plate 321 has gap to each other, but due to multi-disc steel plate 321 between fastened by angle iron connecting piece 322, to steel plate 321
For monomer, it is firm connection each other.
Preferably, the thickness of backing plate 323 is 10mm.
It should be noted that it is larger initially firm so that it is provided in big earthquake centre by the said structure of stopping means
Degree and yield strength, after its fracture failure, shock isolating pedestal body 2 can obtain preferable isolating affection, and it has
Multi-disc steel plate structure also allows for being changed after big shake.
The fastening of multi-disc steel plate 321 is implemented in the following way, and bolt 5 runs through multi-disc steel plate 321 by multi-disc steel plate
321 are fastened on a side end face of angle iron connecting piece 322；Steel plate limiting section 32 is by as follows with steel cushion block 31 and gusset piece 1
Mode is implemented, and another side end face, steel cushion block 31 and two gusset pieces 1 that bolt 6 runs through angle iron connecting piece 322 are spacing by steel plate
Portion 32 is fastened between two gusset pieces 1.Preferably, angle iron connecting piece 322 is an angle steel with vertical angle steel.During assembling, will
Backing plate 323 interval is placed on the precalculated position of multi-disc steel plate 321 end, notices that holding is opened on multi-disc steel plate 321 lateral body surface
The position of screw is corresponding, efficiently bolt 5 can be inserted wherein.Then, two groups of bolts amounting to eight high intensity
Sequentially pass through in the larger angle steel of above-mentioned rigidity 322 and the corresponding bolt hole of multi-disc steel plate 321 and multi-disc steel plate 321 is connected on one
Act the fastening completing multi-disc steel plate 321, steel plate limiting section 32 assembling finishes.
And then, steel plate limiting section 32 is fastened on two gusset pieces 1.Specifically, respectively by another for angle steel 233 side end face
The screw be aligned steel cushion block 21 opening up and the corresponding screw position of two gusset piece 1.Then, many screw rods 6 sequentially pass through above-mentioned rigidity
Steel plate limiting section 32 is fastened between two gusset pieces 1 for larger angle steel 322, steel cushion block 31 and two gusset pieces 1, stopping means
31 assemblings finish.
After the completion of assembling, the relative position relation of each component and two gusset pieces 1 is as follows, and the firm cushion block 31 of stopping means 3 is tight
Gu on two gusset pieces 1, being fixed with steel plate limiting section 32 between it, the multi-disc steel plate 321 in steel plate limiting section 32 couples with two
Plate 1 keeps vertical state；Two shroudings 21 of shock isolating pedestal body are fastened on two gusset pieces 1, be fixed with core print seat and prop up between it
Support part 22, the stem stem 221 in core print seat supporting part 22 and two gusset piece 1 keep the state of Relative vertical, and laminated steel plate 222 and folded
Layer rubber 223 then keeps opposing parallel state with two gusset pieces 1.
The Multifunctional vibration-isolating device of the present invention in the specific implementation, when there being load action on gusset piece 1, as little shake
Or the geological disaster such as middle shake, stopping means 3 can be that whole Multifunctional vibration-isolating device provides larger initial stiffness and surrender just
Degree.As shown in figure 5, being the resilience model schematic diagram of Multifunctional vibration-isolating device of the present invention, wherein, a point is multi-functional shock insulation dress
The elastic limit put, when Multifunctional vibration-isolating device moves to a point by o point, stopping means 3 reach elastic limit, in the process,
Shock isolating pedestal body 2 is in the elastic working stage.A point is broken a little for stopping means 3, i.e. displacement reaches stopping means 3 during dy1
Deactivate, only shock isolating pedestal body 2 works independently, hesteresis curve moves along the hesteresis curve of shock isolating pedestal body 2,
It is the unloading rigidity of shock isolating pedestal body 2 along path de during unloading.Before stopping means 3 are broken, along combination during unloading
The elastic stiffness unloading of seat.As can be seen here, after stopping means 3 fracture failure, the stem stem of shock isolating pedestal body 2 is surrendered,
But it still can continue to provide the effect of shock insulation, and molding casting does not destroy in gusset piece 1 upper component.
Implement the Multifunctional vibration-isolating device of the embodiment of the present invention, because Multifunctional vibration-isolating device is in the week of shock isolating pedestal body
Around arranging multigroup stopping means, stopping means can provide larger initial stiffness and surrender for Multifunctional vibration-isolating device to collarette
Intensity, when normal working load, small earthquakes geological disaster occur, can effectively limit the displacement of bridge superstructure, carry
Rise its firm performance；After stopping means are because of big shake fracture failure, shock isolating pedestal body can play preferable isolating affection, protects
Component on shield gusset piece does not destroy.This Multifunctional vibration-isolating device limits bridge under frequently occurred earthquake and design geological process
Superstructure displacement, plays preferable function of shock insulation under rarely occurred earthquake effect, and clearly, damper effect substantially, constructs stress
Simply, it is easy to construct.
Above disclosed be only present pre-ferred embodiments, certainly the right model of the present invention can not be limited with this
Enclose, therefore equivalent variations, still belong to the scope that the present invention is covered.
