The utility model discloses a prevent parallel oscillation device prevent earthquake process in the parallel wave, the rubber body plays the effect of anti parallel resistance, oscillation device passes through the cooperation in damping spring and bulb ball groove about preventing, shakes the influence to the pontic about preventing among the earthquake process, reduces the destruction degree to the pontic, reduces the loss.
Description
Technical field
This utility model relates to bridge structure technical field, specifically, relates to the damping knot of a kind of bridge
Structure.
Background technology
Bridge Seismic structure, passes to the pontic on earth's surface after buffering by the shaking force at the bottom of ground, reduces earthquake
The shaking force damage to pontic, how to invent a kind of bridge structure, it is ensured that crossstructure is under load action
Meet the multifarious deformation requirements of ground.The most general bridge pad mainly have steel construction shock-damping structure,
Polytetrafluoroethylene bearing (sliding support), rubber shock-absorbing structure, coagulation shock-damping structure and lead shock-damping structure etc..
The shock-damping structure function admirable of rubber shock-absorbing structure material more several than other, but existing rubber shock-absorbing structure is led to
Often can only realize horizontal damping, damping effect is limited so that rubber shock-absorbing device making on bridge
Use and come with some shortcomings, the shock-damping structure requirement of some specific uses now can not be met simultaneously.
How bridge structure, under severe earthquake action, produces bigger relative displacement between upper and lower part constructs, works as position
When shifting amount exceedes actual restrainer length or the limit of bridge, will fall beam, causes the interruption of traffic,
Bring extreme difficulties to disaster relief work, cause huge loss.Existing anti-fall girder apparatus mostly be individually designed,
Installing, the cost that bridge consumptive material is many, transport is installed is high.
Utility model content
The technical problem to be solved in the present invention is to develop a kind of concussion being both possible to prevent pontic parallel direction, again
It is possible to prevent the pontic that pontic shakes up and down.
For solving the problems referred to above, this utility model be the technical scheme is that the shock-damping structure of a kind of bridge,
Including pontic, it is provided with anti-parallel rocking equipment below described pontic, is provided with below described anti-parallel rocking equipment
Anti-upper and lower rocking equipment；
Described anti-parallel rocking equipment includes friction plate, and upper friction plate connects rubber bodies, sets in rubber bodies
Having some steel plates, rubber bodies connects lower friction plate；
Described anti-upper and lower rocking equipment includes upper mounted plate, and upper mounted plate connects some connecting rods, connecting rod another
End connection has bottom plate, connecting rod to be provided with damping spring, also sets between fixed plate and bottom plate
There are some support beams.
A kind of improvement as technique scheme: described connecting rod is respectively arranged at two ends with upper bulb and lower bulb,
Fixed plate is provided with some upper bulb grooves, and the corresponding upper bulb groove of bottom plate is provided with some lower bulbs
Groove, described upper bulb is arranged with upper bulb slot fit, and lower bulb is arranged with lower bulb slot fit.
A kind of improvement as technique scheme: described connecting rod is provided with four, and steel plate is provided with four pieces, supports
Beam is provided with four.
A kind of improvement as technique scheme: be provided with dividing plate between described pontic and upper friction plate.
Owing to have employed technique scheme, compared with prior art, this utility model is by anti-parallel concussion
Device prevents parallel in seismic process waving, and rubber bodies plays the effect of anti-parallel resistance, prevents shaking dress up and down
Put coordinating by damping spring and bulb ball groove, prevent from seismic process shakes up and down the impact on pontic,
Reduce the destructiveness to pontic, reduce loss.
The utility model is described in further detail with detailed description of the invention below in conjunction with the accompanying drawings.
