External cup-mouth-shaped socket type connection prefabricated assembled bridge pier
The invention relates to an externally-attached cup mouth type socket-and-spigot type connection prefabricated assembly bridge pier. The externally-attached cup mouth type socket-and-spigot type connection prefabricated assembly bridge pier is connected with a lower structure. The externally-attached cup mouth type socket-and-spigot type connection prefabricated assembled pier comprises a prefabricated pier body and a cup mouth assembly. The cup opening assembly comprises cup opening stirrups and cup opening concrete; cup rim longitudinal ribs are arranged on the lower structure; the cup opening stirrups are bound in the circumferential direction of the prefabricated pier; the cup rim longitudinal bars are positioned through cup rim stirrups; the upper ends of the cup-opening longitudinal bars are arranged in the externally attached cup-opening type socket-and-spigot type connection prefabricated assembled bridge pier, and the lower ends of the cup-opening longitudinal bars are fixed in the lower structure; the cup opening concrete is poured in the circumferential direction of the prefabricated pier; shear key teeth are arranged on the socket section of the prefabricated pier or the surface is subjected to roughening treatment, so that vertical shear force is reliably transmitted to cup opening concrete; the height of the cup opening assembly is larger than the minimum anchoring length of the bridge pier longitudinal bars and the cup opening longitudinal bars. Compared with the prior art, the method is large in construction tolerance, high in construction speed, high in punching bearing capacity, clear in force transmission mechanism and convenient to popularize and apply.
本发明涉及一种外附杯口型承插式连接预制拼装桥墩，外附杯口型承插式连接预制拼装桥墩与下部结构连接；外附杯口型承插式连接预制拼装桥墩包括预制桥墩、杯口组件；杯口组件包括杯口箍筋、杯口混凝土；下部结构上设有杯口纵筋；杯口箍筋绑扎于预制桥墩周向；杯口纵筋通过杯口箍筋定位；杯口纵筋的上端设于外附杯口型承插式连接预制拼装桥墩中，下端固定于下部结构中；杯口混凝土浇筑于预制桥墩周向；预制桥墩的承插段设置剪力键齿或表面粗糙处理，以保证竖向剪力可靠传递至杯口混凝土；杯口组件的高度应大于桥墩纵筋和杯口纵筋的最小锚固长度。与现有技术相比，本发明施工容差大，施工速度快，冲切承载力高，同时传力机制明确，便于推广和应用。
