Prefabricated pier shell type anti-seismic connecting structure
The invention discloses a prefabricated pier shell type anti-seismic connecting structure. The lower portion of a prefabricated pier is made into a shear groove, surface galling treatment is conductedbefore installation, a positioning cushion block is arranged on the top face of a pile foundation, a cushion layer is arranged between the pile foundation and the prefabricated pier, a prefabricatedpier main rib is cut off at the end, and the pile foundation main rib extends outwards, wherein the joint main reinforcements are pre-buried in the bearing platform, the transverse reinforcements arespiral stirrups or annular reinforcements and are arranged on the outer rings of the pile foundation main reinforcements, and the post-cast joint is cast at the joint of the prefabricated pier and thepile foundation, thus, shell type connection between the prefabricated pier and the lower structure is achieved, on-site steel bar connection is not needed, and construction is convenient, rapid andefficient, on-site grouting connection is not needed, and the construction quality is controllable and high in quality; by extending the pile foundation main reinforcements outwards and arranging thetransverse reinforcements, the ductility is good, the connecting structure can be used for connecting prefabricated bridge lower structures in high earthquake areas, and the application range is wide.
本发明公开了一种预制桥墩壳式抗震连接结构，预制桥墩下部做成剪力槽，安装前进行表面拉毛处理，所述的桩基础顶面设置定位垫块，桩基础与预制桥墩间设置垫层，预制桥墩主筋在端部截止，所述的桩基主筋外伸；所述的接头主筋预埋承台，所述的横向钢筋为螺旋箍筋或环筋，设置在桩基主筋外圈，所述的后浇接头浇筑在预制桥墩与桩基础连接处。从而实现预制桥墩与下部结构间壳式连接，无需现场钢筋连接、施工方便快捷，高效；无需现场灌浆连接，施工质量可控，优质；通过外伸桩基主筋和设置横向钢筋，延性良好，可用于高地震区预制装配式桥梁下部结构连接，适用范围广。
