Description
Technical field
Isolation bridge technical field is the utility model is related to, specially a kind of isolation bridge device.
Background technology
Isolation bridge device just refers to consume the seismic force of earthquake using seismic isolation technology, avoids the considerable damage of earthquake
Power damages bridge.Bridge vibration isolation is then to utilize vibration-isolating system, tries to prevent seismic energy from entering agent structure.
Bridge pad is to connect bridge superstructure and the important component of substructure, and it can be by the anti-of bridge superstructure
Power and displacement and the reliable substructure for passing to bridge of the deformation of corner, when the inertia force that superstructure transmits is more than bridge
During the intensity of bearing, bearing anchor bolt can be caused to extract cutting and support body structure destruction, in turn result in bridge collapse, endangered
The life security of victimization, cause huge property loss.
Utility model content
The purpose of this utility model is to provide a kind of isolation bridge device, asked with solve to propose in above-mentioned background technology
Topic.
To achieve the above object, the utility model provides following technical scheme：
A kind of isolation bridge device, including base, support body, vibration damper plate, division board, shock insulation ball and limiting plate, bottom
The top of seat is provided with bottom cavity, and the bottom wall of bottom cavity is provided with shock insulation chamber, and shock insulation intracavitary is uniformly provided with some shock insulation balls, it is all every
The top of shake ball is provided with division board, is to roll connection between division board and shock insulation ball, the top of division board, which is fixedly connected, to be subtracted
Plate is shaken, the top of vibration damper plate is fixedly connected with support body, and vibration damper plate includes spring and plate body, is arranged with support body and base
The limiting plate being engaged, limiting plate are fixed on base by shearing spring.
As the further technical scheme of the utility model, the diameter of shock insulation ball is more than the height of shock insulation chamber.
As the further technical scheme of the utility model, division board is metallic plate.
As the further technical scheme of the utility model, vibration damper plate is combined by spring and plate body integral type.
As the further technical scheme of the utility model, spring is that metal material makes.
As the further technical scheme of the utility model, plate body is that quality of rubber materials makes.
As the further technical scheme of the utility model, limiting plate is annular slab.
Compared with prior art, the utility model is on the one hand by setting shock insulation ball, using shock insulation ball in brisance
Effect is lower to be rolled, and separates brisance, so as to reach the purpose of protection support body structure, on the other hand by setting vibration damper plate, is come
The frequency range that seismic wave energy is larger is avoided, plays the effect of vibration isolation, so as to preferably reach damping, the purpose of shock insulation.

Some shock insulation balls 7 are uniformly provided with shake chamber 6, the diameter of the shock insulation ball 7 is more than the height of shock insulation chamber 6, all described
The top of shock insulation ball 7 is provided with division board 5, is to roll connection, the top of division board 5 between the division board 5 and shock insulation ball 7
Vibration damper plate 4 is fixedly connected with, the top of the vibration damper plate 4 is fixedly connected with support body 3, and the division board 5 is metallic plate, described to subtract
Shake plate 4 includes spring 41 and plate body 42, and the vibration damper plate 4 is combined by spring 41 and the integral type of plate body 42, the spring
41 be that metal material makes, and the plate body 42 is that quality of rubber materials makes, and is arranged with the support body 3 and is engaged with base 1
Limiting plate 8, the limiting plate 8 is annular slab, and limiting plate 8 is fixed on base 1 by shearing spring 9.
When there is seismic force generation, shear studs 9 are cut, and limiting plate 8 loses fixation, shock insulation ball 7 and division board 5
And the rolling friction of base 1, so that seismic force when being delivered to base 1, is rolled by shock insulation ball 7, seismic force is isolated
Open, protect the structure of support body 3, while the vibration damper plate 4 that the bottom of support body 3 is set can absorb substantial portion of brisance, enter
One step plays the effect of shock insulation, so as to effectively protect bridge when big seismic force occurs, reaches shock insulation purpose；Division board 5
With the cooperation of shock insulation chamber 6, shock insulation ball 7 can be effectively limited.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be on the premise of this patent objective not be departed from one skilled in the relevant art's possessed knowledge
Various changes can be made.
