一种大跨度连续梁用具有隔震装置的支座
摘要：
本发明公开了一种大跨度连续梁用具有隔震装置的支座，从上到下依次包括上板、球冠衬板、曲面板和下板，所述上板底面与球冠衬板顶部平面之间设置平面滑板并通过在上板底面设置横桥向限位结构对球冠衬板横桥向两侧进行限位，所述球冠衬板底部球面与曲面板顶部凹面之间设置上球面滑板，所述曲面板底部曲面与下板顶部凹面之间设置下球面滑板，所述下板上设置纵桥向限位结构对曲面板纵桥向两侧进行限位。本发明既能满足桥梁正常使用功能，又具备横向减震功能。
摘要（英）：

The invention discloses a support with a shock isolation device for a large-span continuous beam. The support comprises an upper plate, a spherical crown liner plate, a curved plate and a lower platefrom top to bottom in sequence, wherein a plane sliding plate is arranged between the bottom surface of the upper plate and the top plane of the spherical crown liner plate, a transverse bridge direction limiting structure is arranged on the bottom surface of the upper plate to limit the two transverse bridge direction sides of the spherical crown liner plate, an upper spherical sliding plate is arranged between the spherical surface of the bottom of the spherical crown liner plate and the concave surface of the top of the curved plate, a lower spherical sliding plate is arranged between the curved surface of the bottom of the curved plate and the concave surface of the top of the lower plate, and a longitudinal bridge direction limiting structure is arranged on the lower plate to limit the two longitudinal bridge direction sides of the curved plate. According to the support, the normal use function of a bridge can be met, and the transverse shock absorption function is achieved.
