Replaceable column base for recoverable functional structure
The invention belongs to the technical field of structural engineering steel structures, and particularly relates to a replaceable column base for a recoverable functional structure. The replaceable column base comprises a bottom layer steel column and a foundation 21, wherein the bottom layer steel column comprises a flange 11, a web 12, a bottom plate 13, a reinforcing part and a replaceable anchor bolt; the flange 11 and the web 12 are connected with the bottom plate 13 through welding; the bottom plate 13 of the bottom layer steel column is placed on the top surface of the foundation 21; and a threaded sleeve 22 is pre-buried in the foundation 21, and the threaded sleeve 22 and the foundation 21 are reliably anchored and connected. The replaceable column base can achieve yield energy dissipation under the earthquake effect so as to protect the bottom layer steel column against bending yield failure, and after an earthquake, rapid recovery of the structure function can be achieved by replacing the anchor bolt.
本发明属于结构工程钢结构技术领域，尤其涉及一种用于可恢复功能结构的可更换柱脚，包括底层钢柱和基础21，所述底层钢柱包括翼缘11、腹板12、底板13、加强件和可更换锚栓；所述翼缘11、腹板12均通过焊接与底板13连接；所述底层钢柱的底板13放置于基础21的顶面。基础21内预埋带螺纹套筒22，所述带螺纹套筒22与基础21之间可靠地锚固连接。本发明的可更换柱脚可以实现在地震作用下屈服耗能，以保护底层钢柱不发生受弯屈服失效；在震后可通过更换锚栓实现结构功能的快速恢复。
