Bridge seismic mitigation and isolation support
The bridge seismic mitigation and isolation support comprises an upper supporting plate and a lower supporting plate which are arranged in a spaced mode, a plurality of vertical compression springs are connected to the lower surface of the upper supporting plate, the other ends of the vertical compression springs are connected with the upper surface of the lower supporting plate, and a horizontal guide shaft is arranged above the lower supporting plate in a suspended mode; sliding seats are connected to the guide shafts in a sliding mode, connecting rods are hinged to one ends of the sliding seats, the other ends of the connecting rods are hinged to the lower end of the upper supporting plate, and an acting force counteracting mechanism is arranged at the position, between the two sliding seats, of the guide shaft. According to the bridge support, the vertical stress part of a bridge can be transferred to the horizontal direction, the fatigue degree of the bridge in the vertical direction is reduced through interaction of the acting force counteracting mechanisms, and the bearing strength of the bridge support is improved.
本发明涉及一种桥梁减隔震支座，包括有间隔设置的上支撑板与下支撑板，所述上支撑板下表面上连接有若干竖向压缩弹簧，竖向压缩弹簧另一端与下支撑板上表面连接，所述下支撑板上方悬空设置有水平的导向轴，所述导向轴上滑动连接的滑动座，所述滑动座的一端铰接有连杆，连杆另一端与上支撑板下端铰接，位于两滑动座之间的导向轴上设置有作用力抵消机构，由于竖向压缩弹簧与水平的作用力抵消机构，能够将桥梁竖向的受力部分转移至至水平方向，通过作用力抵消机构相互作用，降低桥梁在竖直方向上疲劳程度，提高桥梁支座的支承强度。
