Description
Technical field
The invention belongs to bridge technology fields, and in particular to a kind of magnetic pole buffer-type communication type drag-line damping limiter.
Background technique
The support arrangement form that China's Short/Medium Span Bridge mainly uses is full-bridge arrangement laminated rubber bearing or middle pier plate
Formula rubber support, abutment pier tetrafluoro slide plate rubber support.This bridge type due between support and beam body and bridge pier without any connection, only
Horizontal seismic force is transmitted by friction, in earthquake support can generate very big displacement, often result in and serious fall beam and touch
The disasters such as hit.
The common limiting device in China has steel plate limiting device, prestress wire limiting device and cable limit dress at present
Set three kinds, respectively steel plate limiter, prestress wire limiter and cable limiter.
Inventor thinks: steel plate limiter can be opposite to the Dun Liang as caused by temperature change etc. under bridge normal operating condition
Restriction effect is played in displacement, is destroyed so as to cause limiting device or bridge structure；Prestress wire limiting device and cable
Although limiting device can avoid this problem by reserving initial slack, since the work of both limiting devices is former
Reason is that the restoring force for tightening generation by steel strand wires or cable plays limit effect, can only limit girder in the position of single direction
It moves, when there is the pier beam relative displacement of opposite direction, steel strand wires or cable can be in relaxed state, cannot generate restoring force.
Therefore, the cable limiting device that same bridge beam two sides are arranged in can't play the role of limit simultaneously, can reduce limit in this way
The working efficiency of position device.
Summary of the invention
The purpose of the present invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of magnetic pole buffer-type communication type drag-line to subtract
Limiter is shaken, can be avoided using the destruction caused by bridge normal deformation of steel plate limiter；It can be realized double-deformation and position
The limit of shifting.
To achieve the above object, the present invention adopts the following technical solutions: a kind of magnetic pole buffer-type communication type drag-line damping limit
Position device, including two rigid rods being overlapped in vertical direction projection, the both ends of the rigid rod are fixed with a connection respectively
Block, the rigid rod being located above are connect by link block with girder, and underlying rigid rod is connect by link block with bridge pier；
Multi-turn drag-line is wound between two rigid rods, the both ends of drag-line are connected by cord clip；
In such a way that rigid rod is connect with bridge pier and girder, the drag-line wound between two rigid rods can limit girder
Relative motion between bridge pier；Drag-line tightens the relative displacement that can limit both direction between girder and bridge pier.
Flat thin magnet is equipped between two link blocks in same vertical direction, it is opposite that flat thin magnet is respectively arranged at two link blocks
Side, the flat thin magnet can attract each other to restrict the relative motion between girder and bridge pier.
By installing flat thin magnet additional at upper link block and lower connecting block, magnet can be passed through before drag-line plays a role
Between magneticaction play the effect of buffering.
Beneficial effects of the present invention:
1) pass through the circulating type arrangement of drag-line, it is ensured that vertical bridge drag-line in both direction when earthquake and collision occur
Offer restoring force can be provided, to limit relative displacement between pier beam within the scope of one controllable, prevented
Beam is fallen, also can meet the length travel demand of bridge in normal operation by the way that free path is arranged.
2) by being vertically connected with installation flat thin magnet at block, the magnetic between magnet can be passed through before drag-line plays a role
Power acts on the effect for playing buffering.
