Caulking structure for socket type connection of prefabricated pier column and bearing platform
The invention discloses a caulking structure for socket type connection of a prefabricated bridge pier column and a bearing platform, the bearing platform is provided with a socket groove for socket of the bridge pier column, a caulking material filling interval is reserved between the outer surface of the bridge pier column and the inner groove wall of the socket groove, and a caulking material is arranged in the area where the caulking material filling interval is located. Dense-tooth shear keys are arranged on the outer surface of the bridge pier column and the surface of the inner groove wall of the socket groove in the circumferential direction in a surrounding mode. According to the caulking structure adopting the dense-tooth shear keys, the force transfer effect of the socket-and-spigot joint part achieves the structural stress performance similar to that of a cast-in-place pier column structure, and the caulking structure has the advantages of being simple, reliable in embedding and fixing, convenient and fast to construct and low in manufacturing cost.
本发明公开了一种预制桥墩柱与承台承插式连接的嵌缝构造，所述承台具有承插所述桥墩柱的承插槽，所述桥墩柱的外表面及所述承插槽的内槽壁之间预留嵌缝材料填充间隔，在所述嵌缝材料填充间隔所在区域内，所述桥墩柱的外表面及所述承插槽的内槽壁表面分别周向环绕设有密齿剪力键。本发明提供了采用密齿剪力键的嵌缝构造，使承插式连接部位传力效果达到与现浇墩柱结构相似的结构受力性能，本构造具有构造简单、嵌固可靠、施工方便快捷、造价经济的特点。
