Self-resetting gradient anti-seismic long and thin steel tube concrete latticed column

The invention discloses a self-resetting gradient anti-seismic long and thin concrete-filled steel tube latticed column which comprises a concrete-filled steel tube column limb, energy dissipation lacing tubes and self-resetting lacing tubes, the energy dissipation lacing tubes and the self-resetting lacing tubes are alternately and evenly arranged layer by layer in the column height direction and welded to the column limb in a penetration welding mode, the energy dissipation lacing tubes are high-ductility low-yield-point steel tubes, and the self-resetting lacing tubes are high-ductility low-yield-point steel tubes. The self-resetting lacing pipe comprises a left sleeve, a right sleeve, a resetting plate spring assembly and a metal hose. The reset plate spring assembly is provided with reset force through two spring steel plates, and the two ends of the reset plate spring assembly are fixed in the left sleeve and the right sleeve through cushion blocks, positioning screws and squeezing devices.
