Description
Technical field
The utility model belongs to Bridge Seismic technical field, the bridge pad being related in civil engineering, more particularly to one
Multidirectional movable bearing support of the kind with bidirectional damping function.
Background technology
Bearing is the critical component that bridge upper load is delivered to substructure.The vertical bridge of movable bearing support to and direction across bridge
Freely activity, is that bridge top vertical load is delivered into substructure, but do not transmit the critical component of horizontal loading.According to every
Principle is shaken, movable bearing support forms vertical bridge to the shock isolation system with direction across bridge under geological process.Although shock insulation extends structure
Natural vibration period and the interior force-responsive for reducing Structures under Earthquake, but the displacement that shock insulation adds bridge superstructure rings
Should.Once the over-large displacement of geological process underbeam is beyond design permissible value, and one side influences the safety of neighbouring bridge, on the other hand
Have 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.
Utility model content
The problem of existing for background technology, the purpose of this utility model are that providing one kind avoids installing limited, structure
Multidirectional movable bearing support with bidirectional damping function compact, easy to maintenance.
To reach above-mentioned purpose, the multidirectional movable bearing support with bidirectional damping function of the utility model design, including bottom
Seat board, footstock plate, the spherical crown between bedplate and footstock plate, it is characterised in that also include positioned at spherical crown and bedplate it
Between lower seat board and the upper base plate between spherical crown and footstock plate；The bedplate middle top surface be provided with parallel longitudinal bridge to the
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.
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.
The beneficial effects of the utility model are：Damped for traditional bearing, vertical bridge to damper, direction across bridge damping
The shortcomings that device is separately installed, vertical bridge is combined on movable bearing support to damper and direction across bridge damper, made normal
In the case that operation and earthquake intensity are little, damper does not play a role substantially, plays a part of common multidirectional movable bearing support, right
Structure will not produce additional force；When earthquake intensity is larger, damper dissipation seismic energy is activated, the ground for reducing structure is rung
Should.Due to cancelling extra installation damper, make compact-sized, the problem of installing space can be avoided be limited, increase bridge
Shock resistance, maintain easily.
In normal operation and little earthquake intensity, damper does not play a role the utility model substantially, plays common branch
The effect of seat；When earthquake intensity is larger, damper dissipation seismic energy is activated.The utility model also avoid bearing, vertical bridge
The problem of being limited to damper, the separately installed time space of direction across bridge damper.
