Assembly type square steel pipe column and independent foundation connecting joint and construction method thereof
The invention provides an assembly type square steel pipe column and independent foundation connecting joint, and relates to the field of building structures, lining steel is arranged at the lower end in a square steel pipe column, a cover plate is arranged at the top of the square steel pipe column, SMA circular energy dissipation pieces are arranged on the cover plate, and springs are connected between the top of the cover plate and the bottoms of the SMA circular energy dissipation pieces; an embedded anchor bolt in the reinforced concrete independent foundation sequentially penetrates through the bottom of the square steel pipe column, the lining steel, the cover plate, the spring and the SMA circular energy dissipation piece to be fixed. The SMA supporting plates are evenly distributed at the lower ends of the outer walls of the four sides of the square steel pipe column, and the angle steel is installed between the SMA supporting plates and the outer walls of the square steel pipe column and fixed to an independent foundation. The opposite-pull screw sequentially penetrates through the lining steel, the side face of the square steel pipe column, the angle steel and the SMA supporting plate to be fixed. The screw rods are adopted for detachable connection, and upgrading and reconstruction of building structure nodes are facilitated. Meanwhile, the built-in energy dissipation sheets and the springs dissipate most earthquake energy, and lateral restoring force is provided for the square steel pipe column. The invention further provides a construction method.
本发明提供一种装配式方钢管柱与独立基础连接节点，涉及建筑结构领域，其中的内衬钢设在方钢管柱内部下端，顶部设有盖板，盖板上设有SMA圆形耗能片，盖板顶部和SMA圆形耗能片底部之间连接有弹簧，钢筋混凝土独立基础中的预埋锚栓依次穿过方钢管柱底部、内衬钢、盖板、弹簧和SMA圆形耗能片以固定；SMA支撑板均布在方钢管柱四侧外壁下端上，角钢安装在SMA支撑板和方钢管柱外壁之间，并固定在独立基础上；对拉螺杆依次穿过内衬钢、方钢管柱侧面、角钢和SMA支撑板以固定。本发明采用螺杆进行可拆卸连接利于建筑结构节点的升级改造。同时内置耗能片和弹簧耗散大部分地震能量，为方钢管柱提供抗侧回复力。本发明另提供一种施工方法。
