UHPC-steel pipe confined concrete assembly column and construction method thereof
The invention relates to a UHPC-steel pipe confined concrete assembly column and a construction method thereof, the UHPC-steel pipe confined concrete assembly column comprises a splicing column and cast-in-place concrete, the splicing column is formed by vertically overlapping and splicing a plurality of hollow prefabricated UHPC-steel sleeve sections, the cast-in-place concrete is poured in the middle of the splicing column, and the upper and lower adjacent prefabricated UHPC-steel sleeve sections are connected together through a connecting assembly; each prefabricated UHPC-steel sleeve section comprises a steel sleeve and a UHPC layer, wherein the steel sleeve is wrapped with the UHPC layer. The UHPC-steel pipe confined concrete assembly column has the advantages of high hoop, high durability, strong interface bonding and high construction efficiency, no column formwork and stud welding work is needed, construction is easy and convenient, the service life of the structure can be prolonged, the material consumption is reduced, the construction cost is reduced, and the ever-increasing engineering requirements are met.
本发明涉及一种UHPC‑钢管约束混凝土装配柱及其施工方法，包括由若干中空的预制UHPC‑钢套管节段沿竖向叠合拼接而成的拼接柱以及浇筑于拼接柱中间的现浇混凝土，上下相邻两预制UHPC‑钢套管节段通过连接组件连接在一起；所述预制UHPC‑钢套管节段包括钢套管和外包在钢套管上的UHPC层。本发明UHPC‑钢管约束混凝土装配柱具备高套箍、高耐久性、强界面黏结和高施工效率的优点，无柱模板和栓钉焊接工作，施工简便，可提高结构使用寿命，节省材料用量和降低施工成本，满足日益增长的工程需求。
