Description
Technical field
The utility model belongs to Bridge Seismic technical field, the bridge pad being related in civil engineering, more particularly to one
Laterally movable bearing of the kind with bidirectional damping function.
Background technology
Bearing is the critical component that bridge upper load is delivered to substructure.The direction across bridge of laterally movable bearing is free
Activity, bridge is indulged to fixation, is that bridge top vertical load and vertical bridge are delivered to substructure, and restained beam and pier to load
Direction across bridge relative displacement critical component.According to shock insulation principle, laterally movable bearing under geological process indulge bridge to level
Shear pin can be cut, and turn into multidirectional movable bearing support, form vertical bridge to the shock isolation system with direction across bridge.Although shock insulation extends and finished
The natural vibration period of structure and reduce the interior force-responsive of Structures under Earthquake, but shock insulation adds the displacement of bridge superstructure
Response.For the over-large displacement of geological process underbeam once beyond design permissible value, one side influences the safety of neighbouring bridge, the opposing party
Face has the danger of beam.
At present, generally vertical bridge to or direction across bridge damper is additionally set and seismic energy and prevents excessive position to dissipate
Move, this is not only cumbersome for installation, it is complicated to safeguard, influences bridge appearance, and installing space is limited sometimes, and the extra vertical bridge of installation is to subtracting
Shake damper and direction across bridge shock absorber is extremely difficult, construction is complicated.

One slides flange, and footstock plate middle part bottom surface is provided with the second of parallel direction across bridge and slides flange, the lower seat board middle part bottom surface
Coordinate the first chute provided with flange is slided with described first, the upper base plate middle top surface is provided with matches somebody with somebody with the described second slip flange
The second chute closed；The top of the bedplate is provided with a lower class limit hyte part, and the lower limit component is located at the phase of lower seat board
To both sides, and be connected to the side wall of the lower seat board, and the line parallel longitudinal bridge for the lower limit component being oppositely arranged to；Under described
Limit assembly is connected with prestressing force at the top of the bedplate.
Preferably, in addition to one group of first damper of lower seat board opposite sides is located at, described first subtracts
Shake the damper direction of motion parallel described first and slide flange.
Preferably, first damper is viscous damper.
Preferably, first damper includes piston rod, trunk-piston cylinder body and fixing device, the tubular
Piston oil-cylinder physical efficiency is slided along the piston rod；The both ends of piston rod are fixed on the top surface of bedplate, institute by the fixing device
State lower seat board side wall and be provided with the wing plate for engaging the trunk-piston cylinder body.
As another preferred scheme, in addition to one group of second damper of footstock plate opposite sides is located at, described
The two damper directions of motion parallel described second slide flange.
Preferably, second damper is mild steel damper.
Preferably, the second damper both ends and footstock plate pin joint, middle part and upper base plate pin joint.
Preferably, the lower seat board homonymy be provided with the lower limit component of two lower limit components and homonymy on
First slip flange is arranged symmetrically.
It is further preferred that lower power transmission component is provided between the lower limit component and the lower seat board；The lower power transmission

The beneficial effects of the utility model are：For traditional laterally movable bearing, bridge is indulged to damper, direction across bridge
The shortcomings that damper is separately installed, vertical bridge is combined to laterally movable branch to damper and direction across bridge damper
On seat, in the case of making normal operation and earthquake intensity little, the vertical bridge of bearing is not cut to spacing, and damper is not sent out substantially
The effect of waving, play a part of common laterally movable bearing, additional force will not be produced to structure；When earthquake intensity is larger, also
It is the design shear that brisance exceeds lower limit component, lower limit component is cut, and laterally movable bearing is become bi-directional movable branch
Seat, at the same activate vertical bridge to or direction across bridge damper dissipation seismic energy, reduce the seismic response of structure.Due to cancelling extra peace
Damper is filled, makes compact-sized, the problem of installing space can be avoided be limited, increases the shock resistance of bridge, it is convenient to tie up
Shield.
The bearing of the present invention cancels extra installation damper and anti-fall girder apparatus, avoids that installing space is limited to ask
Topic, and it is compact-sized, it is easy to maintenance, it will to obtain significant economic and social benefit.
