Method and structure for connecting prefabricated pier column-bearing platform socket-and-spigot joint in medium-high intensity area
The invention discloses a connecting method and structure for a prefabricated pier column-bearing platform socket-and-spigot joint in a medium-high intensity area, and belongs to the field of bridge engineering.The connecting method comprises the steps that a prefabricated pier column, a prefabricated bearing platform, a connecting pipeline and a connecting steel bar are poured and connected into a whole through a high-performance connecting material; in order to guarantee the connection strength, the prefabricated pier column is inserted into the socket groove of the prefabricated bearing platform, connection is conducted through the connecting steel bars in the connecting pipeline, meanwhile, a high-performance connecting material is poured into a gap between the socket groove and the prefabricated pier column, and the connection strength of the prefabricated pier column is guaranteed. By mainly adopting a socket joint connection mode, combining a metal corrugated pipe or prestress connection mode and prefabricating important components such as bridge pier columns and bearing platforms, construction quality and joint anti-seismic performance requirements are guaranteed, construction progress is accelerated, the height of the bearing platforms is reduced, engineering cost is reduced, and the problems that bridge construction progress is slow in medium and high intensity areas, and construction cost is low can be solved. A traditional socket method is large in bearing platform height and high in manufacturing cost.
本发明公开了一种中高烈度区预制墩柱‑承台承插式节点连接方法与构造，属于桥梁工程领域，包括：预制墩柱、预制承台、连接管道和连接钢筋，利用高性能连接材料灌注连接为整体；为保证连接强度，预制墩柱插入预制承台的承插槽中，通过连接管道内部的连接钢筋进行连接，同时将高性能连接材料灌注至承插槽与预制墩柱之间的空隙，保证其连接强度。本发明以承插式节点连接方式为主，结合金属波纹管或预应力连接方式，通过预制桥梁墩柱及承台等重要构件，保证施工质量和节点抗震性能要求同时，加快施工进度，减小承台高度，降低工程造价，可解决中高烈度地区桥梁施工进度慢，传统承插方法承台高度大、造价高的问题。
