Built-in energy dissipation connecting rod mechanism for prefabricated assembled hollow pier
The built-in energy dissipation connecting rod mechanism comprises a plurality of energy dissipation units, the energy dissipation units are sequentially arranged on the two sides of the inner wall of the hollow pier at different heights in a left-right crossing mode, and each energy dissipation unit comprises an energy dissipation sleeve, a steering plate and a transmission rod; the steering plate is rotatably fixed to the inner wall of the hollow pier, one end of the transmission rod is rotatably connected with the steering plate, the other end of the transmission rod is rotatably connected with the steering plate of the adjacent energy dissipation unit, one end of the energy dissipation sleeve is rotatably fixed to the inner wall of the hollow pier, and the other end of the energy dissipation sleeve is rotatably connected with the steering plate. When the pier vibrates, the transmission rod can drive the steering plates at all heights to rotate, then the energy dissipation sleeve is driven to stretch out and draw back, and vibration of the hollow pier is converted into heat energy. Compared with the prior art, the built-in energy dissipation device has the advantages that the appearance of a bridge is not affected, and meanwhile, a good energy dissipation effect is achieved for a first-order mode or a high-order mode.
本发明涉及一种预制拼装空心桥墩内置型耗能连杆机构，包括多个耗能单元，各个耗能单元依次左右交叉设置在空心桥墩不同高度处的内壁两侧，所述耗能单元包括耗能套筒、转向板和传动杆；所述转向板可转动固定在空心桥墩内壁上，所述传动杆的一端可转动连接转向板，另一端可转动连接相邻耗能单元的转向板，所述耗能套筒的一端可转动固定在空心桥墩内壁上，另一端可转动连接转向板。在桥墩发生振动时，所述传动杆能带动所有高度处的转向板发生转动，进而带动耗能套筒伸缩，将空心桥墩的振动转化为热能。与现有技术相比，本发明属于内置型不影响桥梁美观，同时对于一阶或高阶模态均具有较好的耗能效果。
