Abstract
The invention provides a lead core rubber bearing. The lead core rubber bearing is formed by processing a plurality of rubber pad layers in stacking mode, wherein a hole is formed in the middle of the rubber bearing, and a lead rod is inserted in the hole. According to the lead core rubber bearing, the lead rod is inserted in the middle of the rubber bearing, and therefore the lead core rubber bearing has good damping characteristics and rigidity.
Description
Technical field
The present invention relates to a kind of lead core rubber support, belong to vibration abatement field.
Background technology
Rubber pad base isolation system is the earthquake isolating equipment the most widely using at present, and modal is multilayer rubber bearing, by natural rubber, is made, and has good elasticity.But, himself there is no obvious damping characteristic, generally to be used in conjunction with damper.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, and a kind of lead core rubber support is provided, and has good damping characteristic and rigidity.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A lead core rubber support, in the perforate of the middle part of neoprene bearing, and pours into lead rod.
Further, to be that a plurality of rubber spacers are stacking process described neoprene bearing.
A kind of lead core rubber support of the present invention, pours into lead rod at neoprene bearing middle part, has good damping characteristic and rigidity.
The specific embodiment
Below the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein, only for description and interpretation the present invention, is not intended to limit the present invention.
A lead core rubber support, to be that a plurality of rubber spacers are stacking process neoprene bearing, in the perforate of the middle part of neoprene bearing, and pours into lead rod.
Lead rod plays two effects, and the one, help bearing earthquake energy to a greater extent, when lead for retractable pencil deforms, the damping action of bearing obviously improves, thereby plays the effect that intercepts seismic forces together with bearing; The 2nd, the rigidity of raising bearing, and bearing is resisted seismic forces jointly.Lead core rubber support can be used alone in isolation structure, need not damper be set in addition, makes whole isolation structure system become simple.
A kind of lead core rubber support of the present invention, pours into lead rod at neoprene bearing middle part, has good damping characteristic and rigidity.
Finally it should be noted that: the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although the present invention is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
Claims (2)
1. a lead core rubber support, is characterized in that: in the perforate of the middle part of neoprene bearing, and pour into lead rod.
2. a kind of lead core rubber support according to claim 1, is characterized in that: to be that a plurality of rubber spacers are stacking process described neoprene bearing.
