The erect static load lotus that bears.
Referring to Fig. 1 and Fig. 7～11, in the work progress for installing three-dimensional isolation device or in routine maintenance procedure, if
It was found that the tension force of certain precompressed cable wire is not enough, you can the tensioning swivel nut 18-6 turned in cable wire self-locking tensioning anchorage 18 is adjusted.
Under ideal conditions, the vertical ripple of earthquake should be unable to occur to building during building transmission by earthquake isolating equipment
Displacement.This is based on, the operation principle of this example three-dimensional isolation device vertical earthquake isolating is as follows：Referring to Fig. 1, when the vertical ripple of earthquake is produced
When raw dynamic loading overcomes the vertical early stage rigidity, if the dynamic loading above pushes away base 3 along the axis of fairlead 1, drive
The reaction force of pressing plate 5 just compresses downwards disk spring group 4, and building is motionless with shifting on ground for base 3；If the dynamic loading
Along the drop-down base 3 of the axis of fairlead 1, two groups of precompressed cable wires pull two pieces of floating platen relative movement compression dishes respectively
Groups of springs 4, and base 3 is then moved down with ground away from driving pressing plate 5, now building is still motionless.As can be seen here, when earthquake is vertical
When ripple makes ground generation up-down vibration, compressible disk spring group produces elastic deformation and consumes energy.In the same manner, building is in wind shake
Or when flatly rocking in the presence of seismic wave, be no matter pulling force or pressure to which to the dynamic loading that the three-dimensional isolation device is produced
The compressible disk spring group of power produces elastic deformation and consumes energy.
