The invention discloses a recycled concrete L-shaped steel tube special-shaped column. The special-shaped column is formed by welding a round steel tube and two U-shaped steel tanks, common aggregate concrete is poured into the U-shaped steel tanks, and recycled aggregate concrete is poured into the round steel tube; and anti-shear bolts are welded in the U-shaped steel tanks. Through the adoption of the steel tube with large diameter on the corner of the L-shaped special-shaped column, the recycled concrete is restrained, the force-bearing performance is improved, the torsion capacity is improved, and the bearing capacity and the shock resistance of the recycled concrete restrained by the steel tube are improved, the doubt of people on the poor performance of the recycled concrete is lowered, the recycled concrete can be popularized and applied to the high-rise buildings and the construction waste can be recycled. The recycled concrete L-shaped steel tube special-shaped column disclosed by the invention can be applied to the high-rise buildings and regions with high seismic intensity, and the application range of the recycled concrete is enlarged. Furthermore, the externally coated steel plate and steel tube can be used as templates, so that the templates are saved, the construction is accelerated, and the economic benefit is improved.
