Installing and using for convenience, the bottom of described heavy multi-directional ball is provided with screw rod, and heavy multi-directional ball is embedded in high-damping rubber cushion by screw rod；The bottom of described bearing is provided with fixing base plate, and described fixing base plate is provided with screw.
For the ease of the swing of hemispherical mass, the radian of described circular arc type concave surface is consistent with the hemisphere radian of hemispherical mass.
In order to reduce cost, convenient use, described bearing is steel-shelled concrete solid construction, and described hemispherical mass is all steel or steel-shelled concrete solid construction.
In order to more preferable control structure is from the vibrations of different directions, the top of described hemispherical mass is connected with bearing by four oblique pull springs, the angle of adjacent two oblique pull springs is 90 °, and it is provided with an antivibrator between each two oblique pull spring, the angle of adjacent two antivibrators is 90 °, and adjacent oblique pull spring and the angle of antivibrator are 45 °；The junction of described antivibrator is bulb hinged, and it is Effects of Viscous Fluid Damper that the torsion of certain angle, described antivibrator can occur.
The present invention has the advantage that relative to prior art
The present invention wind of different directions can be shaken and seismic structural reaction be controlled, wind shake and geological process lower semisphere form quality gauge block can universal swing, the motion energy dissipating simultaneously of oblique pull spring and Effects of Viscous Fluid Damper can be made during swing.
The present invention can adjust corresponding oblique pull spring rate according to free vibration period of structure, goes back adjustable hemispherical mass from heavy multi-directional ball rail contact points height adjustment frequency to be applicable to the different frequency of different high-level structure, and has automatically reset function.
The present invention arranges cushion below heavy multi-directional ball track can effectively buffer the impulsive force that hemispherical mass is vertical.
The present invention whole device simple structure, stability and durability are high, and energy consumption effect is good；Dependent response is sensitive, automatically activates and should be able to get well, improves the comfort of high-level structure, it is possible to skyscraper, tall and slender structure are risen good protective effect.
