Description
Technical field
The utility model belongs to technical field of bridge more particularly to a kind of vibration absorption and isolation support.
Background technology
Chinese terrain is complex, and earthquake is multiple, thereby results in bridge collapse and directly contributes personnel's property loss, interruption of communication.
It analyzes and researches to earthquake genesis mechanism in various of China seismic isolation technology and specification, passes through the technological means such as shock insulation, damping
Shock insulation, Aseismatic Design are carried out to bridge pad, when earthquake, ground motion passes through bearing internal structure movement consumption or reduces earthquake
Can, the energy transmission of seismic wave generation is reduced to greatest extent to holder top, causes beam body that must destroy.
Currently, the aseismatic bearing that domestic bridge uses mainly have high-damp rubber support, speed lockup's device bearing, pendulum every
Bearing is shaken, high-damping glue bearing can provide earthquake resistance in support displacement using the damping characteristic of rubber, reduce and absorb ground
Load is shaken, but rubber support rubber is easy to aging；Speed lockup's device bearing processing technology is cumbersome, is easy leakage loses shock-absorbing function；
Pendulum shock isolating pedestal volume is big, and since hyperboloid all uses the smaller friction pair of friction coefficient, seismic energy dissipation is smaller, beam when earthquake
Body uplift scope is big, is influenced greatly on superstructure, anti seismic efficiency is undesirable.
Utility model content
The utility model discloses a kind of simple in structure, friction coefficient greatly, significantly absorbs seismic energy, reduces to beam body knot
The vibration absorption and isolation support that structure destroys.
Above-mentioned technical problem is solved using following technical scheme：
A kind of vibration absorption and isolation support, including upper bracket plate and lower support plate, between upper bracket plate and lower support plate from top to bottom
Plane slide plate, upper pendulum and curved surface liner plate, plane slide plate is disposed with to be embedded in the upper surface of pendulum, and be fixed under upper bracket plate
The fixed stainless steel plate in face forms the first friction pair, and above the portion of accommodating is concave spherical surface, interior welding spherical crown mirror face stainless steel, minute surface court
Under, concave spherical surface surrounding has anti-slip, girder falling baffle ring；Curved surface liner plate top is convex large curved surface spherical crown, is inlaid with song above
Face slide plate is adapted with the curvature for the concave spherical surface for above accommodating face, and lower part is small curved surface spherical crown, and curved surface is fixed with below curved surface liner plate
Spherical crown mirror face stainless steel, minute surface is outwardly；On accommodate above face and curved surface liner plate that relative position is fluted, shearing resistance is installed in groove
The pin of power, pin connect upper pendulum and curved surface liner plate, the curved surface slide plate above curved surface liner plate and the recessed ball for above accommodating face
The spherical crown mirror face stainless steel of face welding constitutes the second friction pair, curved surface spherical crown mirror face stainless steel and undersetting below curved surface liner plate
It is secondary to constitute third friction for fixed curved surface slide plate on concave spherical surface above plate.
A kind of above-mentioned vibration absorption and isolation support, above accommodate above face and curved surface liner plate relative position fovea superior groove shape be it is rectangular or
Ellipse is round.
A kind of above-mentioned vibration absorption and isolation support has annular groove on curved surface liner plate, damping cushion rubber, damping cushion rubber is inlayed in annular groove
Position it is opposite with the baffle ring position of upper pendulum.
A kind of above-mentioned vibration absorption and isolation support, upper pendulum both sides are fixed with wear-resisting draw runner, with leading in upper bracket plate relative position
To article on fixed plane stainless steel plate to constitute the 4th friction secondary.
A kind of above-mentioned vibration absorption and isolation support, the lower part spherical crown of curved surface liner plate is than upper ball crown height.
Using the utility model, when bearing works normally, the second friction pair has pin to fix, this friction pair suffers restraints,
Only first friction is secondary horizontally slidable；It is pivoting friction pair that third friction is secondary, the normal deflection deformation of beam body generate corner first
Occur between third friction is secondary, bearing it is normal slide, the functions such as corner meet bridge and normally drive a vehicle stationarity requirement；
When small earthquake, the first friction pair is slided first, non-slip direction horizontal limeit position, due to curved surface liner plate lower ball
Radius surface is small, and spherical crown is than upper ball crown height, and when design ensures that horizontal earthquake power is less than spherical crown and lower surface camber slide plate snap-in force, on ground
When brisance is less than the horizontal shear that pin is born, pin will not be cut, and bearing plays hard anti-formula function；
When middle shake, the first friction pair slides into that maximum position is limited or non-slip direction Horizontal limiting, when earthquake horizontal force
When the horizontal shear born more than pin, pin fracture, the secondary constraint release of the second friction, while seismic energy is consumed, seismic energy
It reduces, opposite sliding, reciprocatingly slides under the action of seismic wave between the second friction is secondary, is dissipated by the frictional resistance of sliding surface
Seismic energy, and extending structure natural vibration period, reach damping and isolation effect, superstructure are made to be protected；
When big shake, pin fracture, when bearing is run at earthquake maximum displacement, the barricade on concave spherical surface connects with damping cushion rubber
It touches and squeezes, further consume seismic energy, damping cushion rubber prevents annular retaining ring rigid collision, beam body is caused to slide；After earthquake, branch
Seat superstructure dead weight along curved surface direction component as restoring force, so that bearing is reset to normal operating conditions.
