Description
Technical field
The utility model relates to bridge pad, particularly a kind ofly swings power consumption while playing earthquake, reduces frequency and reduces the effect bridge friction pendulum support that earthquake destroys top beam body.
Background technology
Bridge pad is the supporting part of bridge span structure, and the bearing reaction of bridge span structure is passed to pier by it, and ensures that bridge span structure meets deformation requirements under load action.General bridge pad mainly contains steel support, polytetrafluoroethylene bearing (sliding support), neoprene bearing, concrete bearing and plumbous bearing etc. at present.Neoprene bearing is than the bearing function admirable of other several materials, but existing neoprene bearing can only be realized longitudinal damping conventionally, and damping effect is limited.And due to some shortcomings of elastomeric material itself, friction factor is larger, damping effect is bad etc., makes in the use of neoprene bearing on bridge to come with some shortcomings, and can not meet the bearing requirement of some specific uses now simultaneously.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bridge friction pendulum support, to reduce the destruction of earthquake to top beam body.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
A kind of bridge friction pendulum support of the present utility model, comprise upper bracket plate and lower support plate, it is characterized in that: the spherical crown liner plate with upper sphere, lower peripheral surface is set between described upper bracket plate and lower support plate, the soffit of upper bracket plate matches with upper sphere, and the upper surface of lower support plate matches with lower peripheral surface; In described lower support plate, be provided with position limiting structure in direction across bridge both sides, this position limiting structure is corresponding with the direction across bridge two sides of upper bracket plate.
Described position limiting structure is to be detachably connected on the limiting plate in lower support plate by caging bolt.
The beneficial effects of the utility model are in the time of normality, to realize normal design displacement and the rotation of beam body, the stopping means of friction pendulum inefficacy in the time of violent earthquake, bearing swing power consumption, reduction seismic frequency, the effect of reduction earthquake to top beam body destruction; Restraint beam body lateral displacement effectively, and by upper bracket plate with can meet the needs of length travel under bridge operation state with the friction pair of position limiting structure.
