Concrete-filled steel tube fabricated seismic isolation joint and construction method
The invention discloses a concrete-filled steel tube fabricated seismic isolation joint and a construction method. The concrete-filled steel tube fabricated seismic isolation joint comprises prefabricated seismic isolation buttresses, seismic isolation layer beams, seismic isolation supports, a foundation and an upper column, and the prefabricated seismic isolation buttresses comprise upper prefabricated seismic isolation buttresses and lower prefabricated seismic isolation buttresses; the seismic isolation layer beams are prefabricated reinforced concrete members, cast-in-place concrete members or prefabricated steel members; seismic isolation supports are connected with seismic isolation support upper embedded parts and seismic isolation support lower embedded parts in the prefabricated seismic insulation buttress through bolts; the foundation is a cast-in-place concrete member; and the upper column is a prefabricated reinforced concrete member or a cast-in-place concrete member. Compared with the prior art, the seismic isolation buttress of the seismic isolation joint adopts a prefabricated member, and other structural members connected with the seismic isolation buttress can be prefabricated or cast in situ; and the seismic isolation joints are assembled on site, the construction efficiency and the construction quality are improved to the maximum extent, connection of all connecting positions is reliable, and the seismic performance similar to that of a cast-in-place concrete structure can be achieved.
本发明公开了一种钢管混凝土装配式隔震节点及施工方法，钢管混凝土装配式隔震节点包括预制隔震支墩、隔震层梁、隔震支座、基础和上柱，其中所述预制隔震支墩包括预制隔震上支墩和预制隔震下支墩；所述隔震层梁为预制钢筋混凝土构件、现浇混凝土构件或预制钢构件；所述隔震支座用螺栓与预制隔震支墩内的隔震支座上预埋件和隔震支座下预埋件连接；所述基础为现浇混凝土构件；所述上柱为预制钢筋混凝土构件或现浇混凝土构件。与现有技术相比，隔震节点的隔震支墩采用预制构件，与之相连的其他结构构件可预制也可现浇；隔震节点现场装配，最大程度地提高施工效率和施工质量，且各连接处连接可靠，可达到与现浇混凝土结构相近的抗震性能。
