Square steel tube concrete column with novel toughening structure and construction method of square steel tube concrete column
The invention discloses a square steel tube concrete column with a novel toughening structure and a construction method thereof, and relates to the technical field of civil engineering, the square steel tube concrete column comprises a square steel tube, core concrete, a reinforcement cage, a first T-shaped anchor rod and a second T-shaped anchor rod, the square steel tube is perpendicular to the horizontal plane, and the reinforcement cage is arranged in the square steel tube; one end of the first T-shaped anchor rod is welded to the inner side wall of the top end of the square steel pipe, the other end of the first T-shaped anchor rod is located in the reinforcement cage, one end of the second T-shaped anchor rod is welded to the inner side wall of the bottom end of the square steel pipe, the other end of the second T-shaped anchor rod is located in the reinforcement cage, and the square steel pipe is filled with the core concrete and wraps the reinforcement cage, the first T-shaped anchor rod and the second T-shaped anchor rod. The technical problems that in the prior art, a square steel tube in a square steel tube concrete plastic hinge area is prone to outward bulging when reaching the yield strength, and consequently the restraining force of the square steel tube on core concrete is uneven and weak are solved, the deformation capacity of the square steel tube concrete column plastic hinge area is enhanced, and the anti-seismic property of the structure is further improved.
本发明公开了一种带新型增韧构造的方钢管混凝土柱及其施工方法，涉及土木工程技术领域，包括方钢管、核心混凝土、钢筋笼、第一T型锚杆和第二T型锚杆，方钢管垂直水平面，钢筋笼设于方钢管内部，第一T型锚杆一端焊接于方钢管的顶端内侧壁，第一T型锚杆的另一端位于钢筋笼内，第二T型锚杆一端焊接于方钢管的底端内侧壁，第二T型锚杆的另一端位于钢筋笼内，核心混凝土填充于方钢管内部并包裹钢筋笼、第一T型锚杆和第二T型锚杆，解决了现有技术中方钢管混凝土塑性铰区的方钢管在达到屈服强度时容易外鼓曲而导致方钢管对核心混凝土约束力不均匀且约束力较弱的技术问题，进而增强方钢管混凝土柱塑性铰区的变形能力和进一步提升结构的抗震性能。
