Description
Technical field
The utility model belongs to the bridge technology field, relates to a kind of friction pendulum locking bearing concretely.
Background technology
China is in circum-Pacific belt and the Asia-Europe area that influences with the multiple district of two big violent earthquakes, is the multiple state of an earthquake.How antidetonation and damping are to carry out the problem that the bridge construction design must be paid much attention to.China is by the continuous foreign study experience of using for reference, and the characteristics and the designing requirement of combination this country, has researched and developed the various earthquake isolating equipments that subtract.The bridge construction of domestic existing application at present subtracts earthquake isolating equipment and mainly contains lead core rubber support, high-damping rubber bearing etc., has also occurred a kind of band damper bearing that damper and bearing are combined in recent years both at home and abroad.But present support style has following deficiency:
(1) lead core rubber support, high-damping rubber bearing since lateral stiffness a little less than, be difficult to satisfy the requirement of railroad bridge power performance aspect, simultaneously since the quality of rubber be difficult for guaranteeing that the durability of bearing can't reach expected result;
(2) band damper bearing has damping characteristic preferably, but when bearing vertical bearing capacity greatly the time, and seat structure complexity, floor space are huge, make that the integral bridge cost is higher; Simultaneously, monolithic subtracts earthquake isolating equipment and is mainly used in fixed bearing, causes the suffered seismic forces of bridge anchor block excessive, and the inefficacy of fixed bearing horizontal restraint means that just damage has taken place bearing, and still there are a lot of practical problems in the reparation after the shake.
(3) sliding friction energy dissipating support existing problems: the cold bonding knot or the condensation of rubbing surface are solid, cause friction factor not guarantee; Friction energy-dissipating is not obvious; Can't automatically reset after the earthquake.
The utility model content
The purpose of this utility model has provided a kind of friction pendulum simple in structure, that shock resistance good, cost is low, the life-span is long and has locked bearing.
The technical solution of the utility model is as follows:
A kind of friction pendulum locking bearing, this bearing comprises pendulum, spherical crown liner plate, concave surface slide unit and lower support plate, describedly go up that the formation cambered surface cooperates between pendulum and the spherical crown liner plate, and can slide relatively between the two, forming sphere between described spherical crown liner plate and the concave surface slide unit cooperates, and can relatively rotate between the two, be provided with the speed lock between described concave surface slide unit and the described lower support plate, and horizontal slip relatively between the two.
Adopt said structure, under normal circumstances the speed lock is inoperative, concave surface slide unit and the relative horizontal slip between the lower support plate can be satisfied the horizontal relative displacement in the zone of reasonableness between beam body and the bridge pier, same spherical crown liner plate cooperates with sphere between the concave surface slide unit can satisfy the rotation requirement, under normal circumstances work hardly for swinging structure, when earthquake speed per hour degree lock taking place with the relative horizontal sliding locking between concave surface slide unit and the lower support plate, with relative swing spherical crown liner plate between realize change in displacement when reach the purpose of shock-damping energy-dissipating by last pendulum this moment, and the process of swing can adapt to and vertically reaches the multidirectional change in location of level; After the earthquake, last pendulum can be returned to horizontal level under the effect of gravity and pressure.Even very little permanent set is arranged, this part permanent set also has the trend of homing.
Described lower support plate is fixed with the lock seat, and two end links of described speed lock are connected with corresponding described lock seat; Described concave surface slide unit both sides have the connection journal stirrup, and this connection journal stirrup is overlapped on the connecting rod of described speed lock and is positioned at the fluid cylinder both sides of speed lock.
Be provided with plane slide plate and guide pad between described concave surface slide unit and the described lower support plate, wherein said described concave surface slide unit and the lower support plate middle part of being positioned at.
Be provided with the rotation slide plate between described spherical crown liner plate and the concave surface slide unit, described going up between pendulum and the spherical crown liner plate is provided with the swing slide plate.
Beneficial effect: the utility model adopts the principle of pendulum, make can be with the active force of the earthquake relative ground of beam body produce certain level or rotation displacement to reach buffering and to consume the purpose of geological process power, thereby play good anti seismic efficiency, especially this structure had both satisfied the bearing requirement of change in displacement under normal conditions to speed lock, lower support plate and the isostructural design of concave surface slide plate with matching, had satisfied the requirement that subtracts shock insulation again.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 structural representation of the present utility model;
Fig. 2 is the scheme of installation of speed lock;
Fig. 3 is a stereogram of the present utility model.
The specific embodiment
Shown in Fig. 1,2,3: a kind of friction pendulum locking bearing, this bearing comprises pendulum 1, spherical crown liner plate 2, concave surface slide unit 3 and lower support plate 4, describedly go up that the formation cambered surface cooperates between pendulum 1 and the spherical crown liner plate 2, and can slide relatively between the two, forming sphere between described spherical crown liner plate 2 and the concave surface slide unit 3 cooperates, and can relatively rotate between the two, be provided with speed lock 5 between described concave surface slide unit 3 and the described lower support plate 4, and horizontal slip relatively between the two.
Described lower support plate 4 is fixed with lock seat 4a, and two end links of described speed lock 5 are connected with corresponding described lock seat 4a; Described concave surface slide unit 3 both sides have and connect journal stirrup 3a, and this connection journal stirrup 3a is overlapped on the connecting rod of described speed lock 5 and is positioned at the fluid cylinder both sides of speed lock 5.
