The invention discloses a square section type prestress ultra-high performance concrete pipe combination column. The column comprises ultra-high performance concrete pipe sections (1) and prestress longitudinal bars (2), wherein the ultra-high performance concrete pipe sections (1) are connected through the prestress longitudinal bars (2), and concrete (3) is poured and filled in the ultra-high performance concrete pipe sections (1). The column is characterized in that the ultra-high-performance concrete pipe sections (1) are hollow pipes which are formed through a centrifugal method and are square outside and round inside, closed stirrups (4) are arranged inside the hollow pipes, through reserved hole channels (5) are formed in the corners in the longitudinal axis direction, and male connectors (6) and female connectors (7) are arranged at the two ends respectively; and the prestress longitudinal bars (2) penetrate through the reserved hole channels (5) of one or more ultra-high performance concrete pipe sections (1), and axial pre-tightening force is applied to the ultra-high performance concrete pipe sections (1) through post-tensioning prestress. The column is suitable for centrifugal production, is convenient for length adjustment, conforms to fabricated construction requirements, has the characteristics of high bearing capacity, favorable durability and the like, and hasfavorable application prospects in fabricated buildings and ocean engineering.
本发明公开了一种方形节段式预应力超高性能混凝土管组合柱，包括超高性能混凝土管节(1)和预应力纵筋(2)，超高性能混凝土管节(1)通过预应力纵筋(2)连接起来，内部浇筑填充混凝土(3)；其特征在于：所述超高性能混凝土管节(1)是采用离心法成型的外部为方形、内部为圆形的空管，在内部配置封闭箍筋(4)，在角部沿纵轴方向设置通长的预留孔道(5)，在两端分别设置公接口(6)和母接口(7)；所述预应力纵筋(2)贯穿一个或多个超高性能混凝土管节(1)的预留孔道(5)，通过后张预应力对超高性能混凝土管节(1)施加轴向预紧力。本发明适用于离心法生产，长度调整方便，符合装配式施工要求，具备承载力高、耐久性能好等特点，在装配式建筑及海洋工程中具有良好的应用前景。
