Energy dissipation three-dimensional isolation bearing with oblique slide damping
The invention discloses an energy dissipation three-dimensional isolation bearing with oblique slide damping, which comprises a three-dimensional isolation device which is arranged between an upper structure and a foundation bearing platform. The three-dimensional isolation device is composed of horizontal isolation units, a friction energy dissipation unit and a vertical isolation unit which are in up-and-down serial connection. The horizontal isolation units are vertical lead rubber bearing are in axial vertical installation. The friction energy dissipation unit consists of an upper friction card slot and a lower friction card slot which are respectively in buckle connection. Through the sliding friction of contact surface , the initial support and dissipation shock/vibration energy is provided, and a certain tensile function is produced. The vertical isolation unit comprises at least two dimensions tilting the lead rubber bearing in parallel connection, which forms a set of cylindrical structure with symmetrical space. The vertical deformation of the vertical isolation unit is transferred into the inclined deformation and expansion displacement of an inclined rubber bearing. The energy dissipation three-dimensional isolation bearing with oblique slide damping also isolates three-direction earthquake and environmental vibration. By using the device of the protected structure or equipment under earthquake vibration/shock/vibration response and shock/vibration transfer will be brought under effective control, and the safety is protected under shock/vibration.
