Assembly type replaceable self-resetting column base device and column base joint
The invention discloses an assembly type replaceable self-resetting column base device and a column base joint. The assembly type replaceable self-resetting column base device comprises a prefabricated concrete column, a prestressed tendon, a column shoe, a column base, an energy consumption clamp, a column base pressing block and a high-damping rubber energy consumption part. A prefabricated concrete column and a column shoe are machined into a whole, prestressed tendon hole channels are formed in the concrete column, the column shoe and the column foot, the concrete column, the column shoe and the column foot are connected through prestressed tendons, anchorage devices and energy consumption clamps, and energy consumption friction surfaces matched with one another are arranged between the column shoe and the column foot. The column foot pressing blocks are distributed around column corners, connected with a foundation and used for restraining movement of column feet, rubber restraining steel plates are arranged on the top faces of the column foot pressing blocks, the rubber restraining steel plates and the rubber restraining steel plates partially anchored to the energy dissipater connecting plates form restraining steel plate sets, gaps between the steel plates are filled with high-damping rubber layers, high-damping rubber energy dissipation components are formed, and the energy dissipater connecting plates are connected with the column shoes. The fabricated column base joint is convenient to construct, high in energy dissipation capacity, high in ductility and small in post-earthquake residual displacement, parts are easy to replace after earthquake damage, and the fabricated column base joint has great significance in achieving rapid recovery of structure functions under strong earthquakes.
本发明公开了一种装配式可更换自复位柱脚装置及柱脚节点，包括：预制混凝土柱、预应力筋、柱靴、柱脚、耗能夹具、柱脚压块、高阻尼橡胶耗能部件。本发明的预制混凝土柱与柱靴加工为一体，混凝土柱、柱靴和柱脚开设预应力筋孔道，通过预应力筋、锚具、耗能夹具将三者进行连接，柱靴和柱脚之间设置相互吻合的耗能摩擦面。柱脚压块分布在柱角周围并与基础连接，约束柱脚运动，柱脚压块的顶面设置橡胶约束钢板，与部分锚固于耗能器连接板的橡胶约束钢板形成约束钢板组，钢板间隙填充高阻尼橡胶层，形成高阻尼橡胶耗能部件，耗能器连接板与柱靴连接。该装配式柱脚节点施工便捷、耗能能力强、延性高、震后残余位移小，且震损后易于更换部件，对实现强震下结构功能的快速恢复具有重要意义。
