Socket-and-spigot joint structure of prefabricated pier column and bearing platform and construction method
The invention discloses a socket-and-spigot joint structure of a prefabricated pier column and a bearing platform adopting high-strength steel fiber reinforced concrete caulking and a construction method. The invention is characterized in that a socket groove is reserved in the position, corresponding to a pier column, of the top of the bearing platform, a prefabricated pier column is hoisted andinserted into a socket groove, high-strength steel fiber reinforced concrete caulking is poured into a gap between the periphery of the pier column and the wall of the socket groove, and firm connection is achieved. The connecting structure of the pier column and the bearing platform is simple, high in embedding and fixing efficiency, convenient to install and operate, relatively low in prefabricating and embedding precision control requirement, high in construction efficiency and safe and reliable in stress, and meanwhile the anti-seismic property of the connecting structure is similar to that of a cast-in-place structure.
本发明公开了采用高强钢纤维混凝土嵌缝的预制桥墩柱与承台的承插式连接构造及施工方法，其特征在于承台顶部对应墩柱的位置预留承插槽，预制桥墩柱吊装插入所述承插槽内，在墩柱四周与承插槽壁之间的空隙中灌注高强钢纤维混凝土嵌缝，实现牢固连接。使得桥墩柱与承台的连接构造简单、嵌固效率高、安装操作方便、预制和预埋精度控制要求相对不高、施工效率高、受力安全可靠，同时其抗震性能也类似现浇结构。
