Multistage anti-seismic pier elastic hinge
The multistage anti-seismic pier elastic hinge comprises a lower spherical crown lining support (4), the upper surface of the lower spherical crown lining support (4) is a downwards-concave cambered surface, an upper spherical crown lining plate (3) matched with the downwards-concave cambered surface is arranged on the upper surface of the lower spherical crown lining support (4), and the lower surface of the upper spherical crown lining plate (3) is in a protruding arc shape. The middle part of the convex arc is matched with the concave arc surface on the surface of the lower spherical crown support (4); steel limiting connecting blocks (6) are annularly and vertically arranged at the edge positions between the upper spherical crown lining plate (3) and the lower spherical crown lining support (4) respectively, and a vertical steel spring (5) is arranged between the steel limiting connecting blocks (6) arranged on the two sides of the upper spherical crown lining plate (3) and the lower spherical crown lining support (4). The hinge has the beneficial effects that the structural design is more optimized, the hinge rotation angle is large, deformation energy consumption is large, the arranged steel spring can consume seismic wave impact in the vertical direction, and translation displacement and rotation displacement are mutually independent and can work cooperatively to jointly bear seismic wave impact from different directions.
本发明一种多级抗震桥墩弹性铰，包括下球冠衬托(4)，下球冠衬托(4)上表面呈下凹形弧面，与下凹形弧面相契合在下球冠衬托(4)上表面设置有上球冠衬板(3)，上球冠衬板(3)的下表面呈凸出的弧形，凸出的弧形中部与下球冠衬托(4)表面的下凹形弧面相契合；在上球冠衬板(3)和下球冠衬托(4)之间的边缘位置分别环向竖直设置有钢限位连接块(6)，在两侧设置的钢限位连接块(6)之间设置有竖向钢弹簧(5)。本发明有益效果：结构设计更优化、铰转动角度大、变形耗能大、设置的钢弹簧可消耗竖直方向的地震波冲击，平动位移和转动位移相互独立又能协同工作，共同承受来自不同方向的地震波冲击。
