Abstract
The utility model discloses a kind of bridge girder anti-seismic bearing, the bridge girder anti-seismic bearing includes upper bracket plate, lower support plate, balanced ball, solid steel ball, sphere friction pair, rubber slab and the low lastics body of macromolecule, the upper bracket plate and lower support plate are the steel plates with circular groove, the circular groove is used to place balanced ball, the radius of the balanced ball is slightly less than the radius of circular groove, the eccentric sphere that the balanced ball is deviateed by the centre of sphere that hollow ball shell and solid steel ball are constituted with barycenter, sphere friction pair is provided with the circular groove of the upper bracket plate and lower support plate, the upper bracket plate sets rubber slab with the gap between the upper and lower of lower support plate, the upper bracket plate sets the low lastics body of macromolecule with the gap between left and right of lower support plate.The utility model simple structure; easy construction; in earthquake; vibration energy is consumed by the reset response of eccentric sphere and frictional damping campaign, good damping effect can be played, while; rubber slab and the low lastics body earthquake energy of macromolecule; protection bridge pad, reduces the energy that earthquake is transmitted to bridge, improves anti-seismic performance.
Description
Technical field
The utility model belongs to bearing technical field, more particularly to a kind of bridge girder anti-seismic bearing.
Background technology
At present, most of aseismatic bearing for being used in bridge construction has complex structure, cost is high, connector is more, apply
The deficiencies such as work inconvenience, damping and isolation effect difference, it is impossible to effectively reduce the relative displacement of bridge pier in earthquake, bring very big safety to ask
Topic.
The content of the invention
It is stronger that the purpose of this utility model is to provide a kind of simple structure, easy for installation, anti-seismic performance and resist displacement ability
Bridge girder anti-seismic bearing.
The purpose of this utility model is achieved through the following technical solutions, the bridge girder anti-seismic bearing include upper bracket plate,
Lower support plate, balanced ball, solid steel ball, sphere friction pair, rubber slab and the low lastics body of macromolecule, it is characterised in that the upper branch
Seat board and lower support plate are the steel plates with circular groove, and the circular groove is used to place balanced ball, the balanced ball
Radius be slightly less than the radius of circular groove, the centre of sphere and barycenter that the balanced ball is made up of hollow ball shell and solid steel ball
Sphere friction pair, the upper bracket are provided with the circular groove of the eccentric sphere of deviation, the upper bracket plate and lower support plate
Plate sets rubber slab with the gap between the upper and lower of lower support plate, and the upper bracket plate sets high score with the gap between left and right of lower support plate
The low lastics body of son.
Certain gap is provided between the balanced ball and upper and lower support plate circular groove.The single solid steel of the balanced ball
Ball bonding is connected to inside hollow ball shell.
The beneficial effects of the utility model are：The utility model simple structure, connector are few, easy construction, it is cheap,
Dependable performance, vibration energy is consumed by the reset response of eccentric sphere and frictional damping campaign, can play good damping effect,
Meanwhile, rubber slab and the low lastics body earthquake energy of macromolecule protect bridge pad, can effectively reduce bridge under geological process
Horizontal displacement, reduce earthquake and be transmitted to the energy of bridge, improve anti-seismic performance.
Brief description of the drawings
Fig. 1 is a kind of structural representation of bridge girder anti-seismic bearing of the utility model.
Specific embodiment
A kind of structure of bridge girder anti-seismic bearing provided by the utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the bridge girder anti-seismic bearing includes upper bracket plate 1, lower support plate 2, balanced ball 3, solid steel ball 4, ball
Face friction pair 5, rubber slab 6 and the low lastics body 7 of macromolecule, it is characterised in that the upper bracket plate 1 and lower support plate 2 are that have circle
The steel plate of arc groove, the circular groove is used to place balanced ball 3, and it is recessed that the radius of the balanced ball 3 is slightly less than circular arc
The radius of groove, the eccentric sphere that the balanced ball 3 is deviateed by the centre of sphere that hollow ball shell and solid steel ball 4 are constituted with barycenter is described
Sphere friction pair 5, the upper bracket plate 1 and lower support plate 2 are provided with the circular groove of upper bracket plate 1 and lower support plate 2
Gap between the upper and lower rubber slab 6 is set, the gap between left and right of the upper bracket plate 1 and lower support plate 2 sets the low lastics of macromolecule
Body 7.
