Description

A kind of shock isolating pedestal ekalead polymer composite
Technical field
The invention belongs to field of rubber technology, is related to a kind of shock isolating pedestal novel high polymer composite, material tool Have with lead metal similar in mechanical property and damping characteristic, available for build, in isolation bridge bearing high-damping lead for retractable pencil replacement.
Background technology
Earthquake is a kind of sudden, and frequency is high, it is difficult to the natural calamity of prediction, to the very harmful of human society.Earthquake And its secondary disaster triggered causes building, a large amount of of bridge facility to collapse and destroy, make the mankind lives and properties cause it is huge Big loss.Compared with traditional firm method anti-seismic technology, the damping effect of the rubber earthquake isolation support based on " base isolation concept " is more To be excellent.In recent years, shock isolating pedestal has become world today's high anti-seismic, the important building of shockproof requirement, the first choice of bridge Scheme.On the one hand critical elements of the shock isolating pedestal as " base isolation ", its major function are supporting building, the weight of bridge Amount, on the other hand it is the dynamic characteristics for changing structural system, mainly extends building, the natural vibration period of bridge, so as to effectively Reduce its earthquake response.
At present, what is be most widely used in shock isolating pedestal is normal stack rubber support and lead core rubber support.(1) it is general Logical laminated rubber bases, are typically manufactured using natural rubber, and natural gum has the characteristics of high flexibility, high resiliency, high intensity, are assigned The good vertical bearing capacity of bearing and horizontal shear deformability.But the damping capacity difference of this bearing is, it is necessary to and damper And with improve damping.Because damper involves great expense, the application of the type bearing is limited;(2) lead core rubber support, it is In normal stack rubber support, one or more lead rods are poured into vertically, so as to improve the damping capacity of bearing.But lead-rubber Bearing equivalent level rigidity is high, often exceeds critical field, and when earthquake occurs, surrender fracture, automatic recovery ability easily occur for lead for retractable pencil Decline.In addition under normal load, the effect of low periodic perturbations, lead for retractable pencil in bearing produces tired failure by shear, under damping capacity Drop.And lead for retractable pencil can also cause serious pollution to environment.
The content of the invention
Ekalead polymer composite belongs to field of rubber technology.It is used to subtract the invention provides new core hybrid material Shake bearing:With high damping properties, the damping ratio of bearing can be increased substantially.Prepared using above-mentioned new core hybrid material Shock mount have the characteristics that excellent damping capacity, equivalent level rigidity be low and low land seismic wave under it is yielding, meet bridge The needs of practical application, realize the replacement of lead for retractable pencil in bearing.
