Self-resetting negative-stiffness three-dimensional shock insulation support
The invention relates to a self-resetting negative-stiffness three-dimensional seismic isolation support which comprises an upper connecting plate, a lower connecting plate and a third connecting plate. The lower connecting plate is positioned below the upper connecting plate; the self-resetting damping unit is positioned between the upper connecting plate and the lower connecting plate; the core tube is arranged between the upper connecting plate and the lower connecting plate; the horizontal sleeves are symmetrically arranged by taking the core tube as a center; two ends of the prestressed tendon respectively penetrate through the core tube and stretch into the two symmetrical horizontal sleeves in a tensioning state; the anchor plugs are fixedly arranged at the end parts of the prestressed tendon and are anchored on the horizontal sleeves; the two sliding plugs and the metal spring set are arranged in the horizontal sleeve in a sliding mode, and an upper connecting rod and a lower connecting rod are arranged on the two sliding plugs in a hinged mode respectively. The device is simple in structure, clear in force transmission and high in bearing capacity, exerts different horizontal and vertical rigidities under the action of earthquakes of different levels, can achieve the earthquake and vibration double-control target of multi-level performance, and has wide application prospects.
本发明涉及一种自复位负刚度三维隔震支座，包括：上连接板；位于上连接板下方的下连接板；位于所述上连接板与下连接板之间的自复位减震单元，其包括介于所述上连接板与下连接板的核心筒、以所述核心筒为中心对称布置的水平套筒、两端分别穿过所述核心筒并呈张紧状态伸入对称的两个水平套筒内的预应力筋、固定安装在所述预应力筋端部并锚固于所述水平套筒上的锚塞，以及滑动布置在所述水平套筒内的两个滑塞和金属弹簧组，两个滑塞上分别铰接布置上连杆与下连杆。本发明构造简单，传力明确，承载能力强，在不同等级地震作用下发挥不同水平和竖向刚度，可实现多级性能的震、振双控目标，具有广阔的应用前景。
