Background technology
Existing rubber support seismic isolation technology is to arrange, between basis and structural base, the shock isolating pedestal that horizontal rigidity is comparatively small, compared with general non-isolation structure, the basic cycle of isolation structure is obviously prolonged, and superstructure vibration under geological process is approximately overall translation.Usually make structures isolation effect effect obvious, the cycle of isolation structure need to be extended for more than the twice of non-isolated structure period, but isolation structure is under Long-period Ground Motions effect, want still to reach isolating affection so, realization degree is relatively difficult, therefore, make isolation structure have good isolating affection under long period shock effect equally and become the focus of current research.
Summary of the invention
The defect existed for prior art, it is an object of the invention to provide one and incidentally damp multidirectional negative stiffness device, make this device in parallel with shock isolating pedestal for isolation structure, thus be possible not only to ensure that isolation structure has good isolating affection under long period geological process equally, and Seismic Isolation of Isolation Layer displacement can be controlled.
For reaching above-mentioned purpose, the present invention adopts the following technical scheme that
One incidentally damps multidirectional negative stiffness device, including the upper and lower connecting plate of upper ball hinged support, the lower upper and lower connecting plate of ball hinged support, upper and lower ball pivot, pre-compressed spring, viscous damper, hexagon socket head cap screw, lateral lockplate；nullThe upper junction plate of described upper ball hinged support is connected by hexagon socket head cap screw is fixing with lower connecting plate，On described upper ball hinged support、Upper ball pivot is stuck in middle connection by lower connecting plate，Described upper ball pivot and viscous damper are by being welded and fixed，Described lower ball pivot and viscous damper are by being welded and fixed，Described upper ball pivot and pre-compressed spring are by the guide rod nested encryptions on upper ball pivot，Described lower ball pivot and pre-compressed spring are by the guide rod nested encryptions on lower ball pivot，Described pre-compressed spring is nested in inside viscous damper，On described lower ball hinged support、Lower ball pivot is stuck in middle connection by lower connecting plate，The upper junction plate of described lower ball hinged support is connected by hexagon socket head cap screw is fixing with lower connecting plate，Described lateral lockplate respectively with on upper ball hinged support、On lower connecting plate and lower ball hinged support、Lower connecting plate is bolted，Whole device vertical axis is symmetrical.
Compared with prior art, the present invention has a following outstanding advantages:
1) provide the power consistent with the direction of motion by pre-compressed spring, thus realize negative stiffness, solve the isolation structure problem that isolating affection is the best under Long-period Ground Motions effect.
2) additional viscous damper is enclosed within outside pre-compressed spring, solves the isolation structure Seismic Isolation of Isolation Layer displacement equations brought due to negative stiffness so that displacement has obtained effective control.
3) device connects down through ball pivot and makes it in parallel with rubber support when isolation structure, can play the effect of optimization isolating affection for the earthquake motion effect of any direction, not have directivity.
4) mechanical property of negative stiffness device can be changed by the parameter of regulation pre-compressed spring and viscous damper, so that it meets design requirement.

Detailed description of the invention
The present invention is described in detail below in conjunction with accompanying drawing and specific embodiment.
As shown in Figures 1 to 7, one incidentally damps multidirectional negative stiffness device, including upper ball hinged support upper and lower connecting plate 1a, 1b, lower ball hinged support upper and lower connecting plate 2a, 2b, upper and lower ball pivot 3a, 3b, pre-compressed spring 4, viscous damper 5, hexagon socket head cap screw 6, lateral lockplate 7；nullThe upper junction plate 1a and lower connecting plate 1b of described upper ball hinged support is connected by hexagon socket head cap screw 6 is fixing，On described upper ball hinged support、Lower connecting plate 1a、Upper ball pivot 3a is stuck in middle connection by 1b，Described upper ball pivot 3a and viscous damper 5 are by being welded and fixed，Described lower ball pivot 3b and viscous damper 5 are by being welded and fixed，Described upper ball pivot 3a and pre-compressed spring 4 are by the guide rod nested encryptions on upper ball pivot 3a，Described lower ball pivot 3b and pre-compressed spring 4 are by the guide rod nested encryptions on lower ball pivot 3b，It is internal that described pre-compressed spring 4 is nested in viscous damper 5，On described lower ball hinged support、Lower connecting plate 2a、Lower ball pivot 3b is stuck in middle connection by 2b，The upper junction plate 2a and lower connecting plate 2b of described lower ball hinged support is connected by hexagon socket head cap screw 6 is fixing，Described lateral lockplate 7 respectively with on upper ball hinged support、Lower connecting plate 1a、On 1b and lower ball hinged support、Lower connecting plate 2a、2b is bolted，Whole device vertical axis is symmetrical.
The connected mode of described upper and lower ball pivot 3a, 3b makes the suitability of this device not by earthquake motion aspect effect.It is internal that described pre-compressed spring 4 is nested in viscous damper 5, not only protects pre-compressed spring 4, and adds the energy dissipation capacity of this device simultaneously.Described upper and lower ball pivot 3a, 3b and pre-compressed spring 4 are by the guide rod nested encryptions on ball pivot so that device is in motor process, and pre-compressed spring 4 will not occur unstable phenomenon.Described lateral lockplate 7 can be in pressured state after making pre-compressed spring 4 pressurized all the time, after device installs, and the lateral lockplate of removal 7.
After the installation of this device, under horizontally shock effect, device occurred level moves, upper and lower ball pivot 3a, 3b rotate thus drive pre-compressed spring 4 and viscous damper 5 to rotate, pre-compressed spring 4 provides the horizontal force consistent with the direction of motion thus provides negative stiffness, viscous damper 5 internal piston moves thus dissipation energy, controls Seismic Isolation of Isolation Layer displacement.Incidentally damp multidirectional negative stiffness device and can be evenly arranged in the surrounding of shock isolating pedestal, changed the mechanical property of negative stiffness device by the parameter of regulation pre-compressed spring 4 and viscous damper 5, so that it meets design requirement.
