The first wearing plate it is provided with, under spherical crown liner plate between plate domed lower surface and the spherical upper surface of spherical crown liner plate
The second wearing plate it is provided with between surface and undersetting upper surface.When bridge temperature deformation makes support displacement
Time beam body have certain lifting, railroad track or highway pavement arching phenomenon, shadow at bearing can be caused
Ring the traffic capacity of road, jump particularly at a high speed car phenomenon；When bridge is because of wind-force, braking, earthquake etc.
Factor can not share horizontal load when producing significant shock.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of without lifting unidirectional damping friction pendulum
Formula bearing, during to eliminate bridge temperature deformation displacement, beam body raises phenomenon, when bridge because of wind-force, braking,
When the factors such as earthquake produce significant shock, part of horizontal load shared by bearing, reduces earthquake to top beam body
The effect destroyed.
It is as follows that this utility model solves the technical scheme that its technical problem used:
Of the present utility model a kind of without lifting unidirectional damping friction pendulum support, including upper bracket plate,
Lower support plate and be positioned at spherical crown liner plate between the two, upper bracket plate lower surface and spherical crown liner plate upper surface
Between there is the first friction pair and be provided with the first wearing plate, in spherical crown liner plate lower surface and lower support plate
There is between surface the second friction pair and the second wearing plate is set, it is characterized in that: described first friction pair
For sphere friction pair, the second friction pair is to the face of cylinder friction pair extended along suitable bridge；Described undersetting
It is provided with base plate below plate, between lower support plate bottom surface and plate top surface, forms planar slide friction pair also

Detailed description of the invention
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
See figures.1.and.2, of the present utility model a kind of without lifting unidirectional damping friction pendulum support,
Including upper bracket plate 2, lower support plate 6 be positioned at spherical crown liner plate 4 between the two, upper bracket plate 2
There is between lower surface and spherical crown liner plate 4 upper surface the first friction pair and be provided with the first wearing plate 3,
There is between spherical crown liner plate 4 lower surface and lower support plate 6 upper surface the second friction pair and to arrange second resistance to
Nog plate 5.Described first friction pair is sphere friction pair, and the second friction pair is to the circle extended along suitable bridge
Cylinder friction pair.Base plate 8, lower support plate 6 bottom surface and base plate it is provided with below described lower support plate 6
Form planar slide friction pair between 8 end faces and be provided with the 3rd wearing plate 7.The horizontal stroke of lower support plate 6
Bridge arranges speed lockup's device 12 outside side, and speed lockup's device 12 is fixed with lower support plate 6, base plate 8
Connect.
When bearing relative sliding velocity is slow, speed lockup's device 12 is not had an effect, it is allowed to it is certainly
