Bridge pier stud and pier stud joint structure thereof
The invention discloses a bridge pier stud and a pier stud joint structure thereof. The pier stud joint structure comprises a lower prefabricated pier stud and an upper prefabricated pier stud, and anannular groove extending in the longitudinal direction from the corresponding upper butt joint face or the corresponding lower butt joint face is further formed in the cylinder wall of the upper prefabricated pier stud or the lower prefabricated pier stud; upper pier stud reinforcing steel bars comprise upper butt joint reinforcing steel bars extending into the annular groove, and lower pier studreinforcing steel bars comprise lower butt joint reinforcing steel bars extending into the annular groove; a circular pier stud connector structure further comprises a grout outlet pipeline arrangedat the top of the annular groove and communicated with the annular groove, and a grout pressing pipeline arranged at the bottom of the annular groove and communicated with the annular groove. And theultra-high performance concrete is filled in the annular groove to form a bedding mortar layer. The technical problems that bridge circular piers are not easy to butt, poor in anti-seismic property and poor in anti-shearing property are solved.
本发明公开了一种桥梁墩柱及其墩柱接头结构，墩柱接头结构包括下预制墩柱和上预制墩柱，所述上预制墩柱或所述下预制墩柱的筒壁内还设有自对应的所述上对接面或者所述下对接面起沿纵向延伸的环形凹槽，所述上墩柱钢筋包括延伸在所述环形凹槽内的上对接钢筋，所述下墩柱钢筋包括延伸在所述环形凹槽内的下对接钢筋；所述圆形墩柱接头结构还包括设置在所述环形凹槽的顶部，且与所述环形凹槽连通的出浆管道，以及设置在所述环形凹槽的底部、且与所述环形凹槽连通的压浆管道；超高性能混凝土填充在所述环形凹槽内形成所述座浆层。解决了桥梁圆形墩不易对接，抗震性能不佳和抗剪性能不强的技术问题。
