Socket and spigot type prefabricated pier with anti-seismic performance and manufacturing method of socket and spigot type prefabricated pier
The invention provides a socket type prefabricated pier with anti-seismic performance and a manufacturing method thereof, and belongs to the field of prefabricated piers, the socket type prefabricated pier comprises a bearing platform unit and a pier column unit, a socket groove of the pier column unit is reserved in the center of a bearing platform base of the bearing platform unit, shear key teeth are arranged on the inner wall of the socket groove, finish rolling deformed steel bars are fixed in the socket groove, and the shear key teeth are arranged on the inner wall of the socket groove. The grouting material is poured in a gap between the bearing platform base and the pier column unit; an abutment connector of the pier column unit comprises a bottom plate, a side plate fixed on the bottom plate, a triangular plate for supporting the side plate and shear studs fixed inside and outside the side plate, meanwhile, a reserved hole is formed in the bottom plate, and a pier column body is fixed inside the abutment connector. The roughness degree of the socket-and-spigot contact surface is increased through the shear key teeth, meanwhile, the bonding force and the shear bearing capacity of the socket-and-spigot type prefabricated pier can be improved through cooperation with the pier and abutment connector, and the connecting performance and the anti-seismic performance of the socket-and-spigot type prefabricated pier can be improved through connection with the finish rolling deformed steel bars.
本发明提供了一种具有抗震性能的的承插式预制桥墩及其制造方法，属于预制桥墩领域，其包括承台单元和墩柱单元，承台单元的承台基座中心预留墩柱单元的承插槽，该承插槽的内壁上设置有剪力键齿，精轧螺纹钢固定在成插槽的内部，灌浆料浇筑在承台基座与墩柱单元的缝隙中；墩柱单元的墩台连接器包括底板、固定在底板上的侧板、支撑侧板的三角板以及固定在侧板内外的剪力栓钉，同时底板上设置有预留孔洞，墩柱主体固定在墩台连接器的内部。本发明通过剪力键齿增加承插接触面的粗糙程度，同时配合墩台连接器能够提高承插式预制桥墩的粘结力和抗剪承载力，并且利用精轧螺纹钢进行连接，能够改善承插式预制桥墩的连接性能和抗震性能。
