Standardized assembly type concrete square tube composite column with constraint pull rod and connecting joint
The standardized assembly type concrete square tube composite column comprises prefabricated square tubes, connecting steel bars, the constraint pull rods and concrete, the connecting steel bars are vertically arranged on the upper portions and the lower portions of the prefabricated square tubes or are arranged in a full-length mode along core filling areas of the prefabricated square tubes, and the connecting steel bars extend out of the ends of the prefabricated square tubes; the restraining pull rod is arranged in the plastic hinge area of the column body, the two ends of the restraining pull rod are fixed to the side wall of the core filling area of the prefabricated square pipe, and concrete is poured into the core filling area of the prefabricated square pipe. The constraint pull rod is arranged in the plastic hinge area, the constraint pull rod can effectively constrain concrete and connecting steel bars in the core grouting area, and the stress performance such as the bearing capacity, the plastic deformation capacity and the ductility of the square tube composite column can be improved. The standardized assembly type concrete square tube composite column with the constraint pull rod is formed by cast-in-place concrete, the concrete square tube composite column can be suitable for different axial forces and bending moments by adjusting the grade of the connecting steel bars and the grade of core grouting concrete, and a standard prefabricated column is selected.
本发明公开了一种带约束拉杆的标准化装配式混凝土方管叠合柱及连接节点，包括预制方管、连接钢筋、约束拉杆和混凝土，连接钢筋沿预制方管灌芯区竖向设置在其上部和下部或者通长设置，连接钢筋伸出预制方管的端部，约束拉杆设置在柱体的塑性铰区，约束拉杆两端固定在所述预制方管的灌芯区侧壁上，混凝土浇筑在所述预制方管的灌芯区中。本发明在塑性铰区设置约束拉杆，约束拉杆能够有效约束灌芯区混凝土和连接钢筋，有助于提高方管叠合柱的承载力、塑性变形能力和延性等受力性能。现场浇筑混凝土组成带约束拉杆的标准化装配式混凝土方管叠合柱，通过调整连接钢筋和灌芯混凝土等级，可使混凝土方管叠合柱适用不同的轴力和弯矩，做到选择标准预制柱。
