Abstract
Triple friction pendulum supports to satisfy seismic action and to superstructure's displacement influence, effectively reduce the destruction of earthquake to the upper portion roof beam body. Including upper bracket board, bottom suspension bedplate and therebetween spherical crown lining board, fix on the lower sphere of upper bracket board and set up first antifriction plate, fixed setting second antifriction plate on the last sphere of bottom suspension bedplate. Set up embedded upper bracket board between upper bracket board and the spherical crown lining board, set up embedded bottom suspension bedplate between bottom suspension bedplate and the spherical crown lining board. It is vice that spherical crown lining board's last sphere and the lower spherical of embedded upper bracket board become to slide the friction, and spherical crown lining board's lower sphere and the last spherical of embedded bottom suspension bedplate become to slide and rub pair. The last sphere of embedded upper bracket board and the face of first antifriction plate form that to slide the friction vice, and the lower sphere of embedded bottom suspension bedplate and the face of second antifriction plate form that to slide the friction vice.
Description
Technical field
This utility model relates to bridge pad, particularly to one when earthquake by swinging friction energy-dissipating, reduce earthquake bridge friction pendulum support that top beam body is destroyed.
Background technology
Bridge pad is the supporting part of bridge span structure, for bridge in earthquake, can play the extending structure cycle, consume the effect of a large amount of seismic energy, be widely used among bridge.The most conventional bridge pad mainly has rubber support, bridle iron, sliding support, concrete bearing, lead bearing and friction pendulum support etc..
Friction pendulum support passes through specific circular arc (ball) face, substantially prolongs basic natural period of structure's vibration, by there is high abrasion and high temperature and friction system are stablized adjustable material and seismic energy is converted into heat energy, it is achieved thereby that shock insulation and the purpose of power consumption.Such as, disclosing a kind of double friction pendulum support in the utility model patent description of Application No. ZL201020261906.6, this pair of friction pendulum support includes pendulum, the bottom, tumbler and sliding part.Wherein, between upper pendulum and tumbler, cambered surface coordinates, and can rotate relatively freely therebetween.Mating spherical surfaces is formed between tumbler and sliding part, and therebetween can the most slidably.Between sliding part and the bottom, cambered surface coordinates, and therebetween can the most slidably.But this bearing can not play anti-fall beam action, its upper bracket is difficult to be returned to initial position after swinging.
Currently used bridge typically can only provide the basic functions such as vertical pressure-bearing, sliding, rotation with the friction pendulum support of building, and its sliding surface is spherical structure, and the spatial volume occupied in the horizontal direction is relatively big, relatively costly.
Therefore, how to ensure that the swing spherical plate of bearing, after the earthquake, is automatically reset by the deadweight of superstructure, it is to avoid adjust operation after shake, the structure of its restraining position is simplified simultaneously, be current problem demanding prompt solution.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of triple friction pendulum support, to meet the geological process Influence of Displacement for bridge superstructure, effectively reduces the earthquake destruction to top beam body.
The technical scheme that the above-mentioned technical problem of this utility model solution is taked is as follows:
Triple friction pendulum support of the present utility model, including upper bracket plate, lower support plate and therebetween spherical crown liner plate, the first wearing plate it is fixedly installed on the lower peripheral surface of upper bracket plate, it is fixedly installed the second wearing plate on the upper sphere of lower support plate, it is characterized in that: embedded upper bracket plate is set between described upper bracket plate and spherical crown liner plate, embedded lower support plate is set between lower support plate and spherical crown liner plate；It is secondary that the upper sphere of described spherical crown liner plate and the lower peripheral surface of embedded upper bracket plate form sliding friction, and it is secondary that the lower peripheral surface of spherical crown liner plate and the upper sphere of embedded lower support plate form sliding friction；It is secondary that the upper sphere of described embedded upper bracket plate and the plate face of the first wearing plate form sliding friction, and it is secondary that the lower peripheral surface of embedded lower support plate and the plate face of the second wearing plate form sliding friction.
Benefit effect of the present utility model is, by upper bracket plate, lower support plate, embedded upper bracket plate, sliding between embedded lower support plate and spherical crown liner plate, can to meet bridge displacement request of different directions after shake；There is the advantage that cost is low, respond well, and the bridge type scope being suitable for is wide.
