Prestress buffering energy dissipation bridge vibration isolation support
The invention discloses a prestress buffering energy dissipation bridge vibration isolation support, and belongs to the technical field of bridge buildings. The prestress buffering energy dissipation bridge vibration isolation support comprises a buffering energy dissipation component, the buffering energy dissipation component comprises a rotating shaft, a rotating connector is arranged above the rotating shaft, a roller device is arranged above the rotating connector, and a sliding roller is arranged on the roller device; a linear steel shaft is arranged below the rotating shaft; a limiting clamping plate is arranged on the rotating shaft, and a prestressed steel strand is fixed in the limiting clamping plate; an upper supporting plate is connected with the upper portion of the buffering energy dissipation component, and a sliding plate is arranged on the upper portion of the upper supporting plate; a lower supporting plate is connected below the buffering energy dissipation component. The prestressed steel strand can provide stress needed by recovery of the support and resist damage of aftershock, can resist translation and rotation in the horizontal direction, have enough energy dissipation capacity and a good post-earthquake self-resetting function, and can effectively consume earthquake energy.
本发明公开了一种预应力缓冲耗能桥梁隔振支座，属于桥梁建筑技术领域。所述预应力缓冲耗能桥梁隔振支座包括缓冲耗能构件，所述缓冲耗能构件包括转轴，所述转轴上方设有旋转连接器，所述旋转连接器上方设有滚轮装置，滚轮装置上设有滑动滚轮；转轴下方设有一字型钢轴；转轴的轴上设有限位夹板，所述限位夹板的内部固定有预应力钢绞线；所述缓冲耗能构件上方连接有上支撑板，上支撑板的上方设有滑动板；缓冲耗能构件下方连接有下支撑板。本发明的预应力钢绞线能够提供支座恢复所需的应力，抵抗余震的伤害，水平方向既可以抵抗平动又可以抵抗转动，具有足够的耗能能力且具有良好的震后自复位功能，可以有效地消耗地震能量。
