Set every oscillation damping method, which is characterized in that upper pressure-bearing steel plate is fixedly connected to support building, and with building, under hold
On the basis of laminated steel is fixed on,
It is adjusted and is closed every the different location that vibration absorber is arranged in building structure according to the performance of upper building structure and multidimensional
Suitable pretightning force and arrangement steel strand wires and the suitable angle of bearing plate, and pretightning force can be read in real time according to scale reading, with
Convenient for being flexibly accurately adjusted, it also can guarantee that the later period is preferably observed；
When the multidimensional is acted on every vibration absorber by horizontal earthquake direction, firstly, core cushion blocking occurs as soft layer
The alternate displacement of horizontal direction, and the response of the horizontal vibrating of building is smaller, and effectively the earthquake of horizontal direction is isolated；
Viscoelastic material in core cushion blocking has biggish damping and good energy dissipation capacity, issues in horizontal earthquake effect

The translation and torsion of upward any angle, ensure that alternate displacement and the torsion of core cushion blocking any angle in the horizontal direction
Turn, while core cushion blocking will form a rigidity weakness with prepressing type tubular damper compared with main structure in the horizontal direction
Layer, this will play the role of vertical earthquake isolating so that the geological process of horizontal direction all angles effectively can dissipate and be isolated；
Compressible energy consumption material in the case where earthquake vertically acts on, in core cushion blocking in viscoelastic material and prepressing type tubular damper
Compressive deformation can occur for material and dissipation vibration energy, while core cushion blocking and prepressing type tubular damper are vertically the same as main body knot
For structure compared to will form a relative rigidity weak floor, this will play the role of vertical earthquake isolating, thus multidimensional can be with every vibration absorber
Play vertical shock insulation and damping effect；
When larger earthquake causes device vertical direction that larger pulling force occurs, due to having been applied in advance by precompressed tubular damper
Add pretightning force, prepressing type tubular damper will bear most pulling force, so that the core cushion blocking at device center be protected to keep away
Exempt to be drawn it is bad, thus multidimensional every vibration absorber have very strong anti-pulling ability；
When Irregular Building Structures cause device vertical direction that larger pulling force and horizontal plane torque occurs under larger earthquake effect
When, having applied pretightning force and steel hinge rope in advance by precompressed tubular damper has certain angle, prepressing type cylinder with horizontal plane
Shape damper will bear most of pulling force and torque, so that the core cushion blocking at center be protected to avoid being drawn badly and being turned round bad, guarantor
Demonstrate,proving multidimensional has very strong anti-pulling and anti-torsion ability every vibration absorber；
In addition, the spring in prepressing type tubular damper, which can provide biggish elasticity when device is pressurized, restores rigidity, this increase
The ability of the resistance to deformation of whole device.
