The utility model discloses a recycled concrete steel pipe L-shaped column. The recycled concrete steel pipe L-shaped column is composed of a round steel pipe and two U-shaped steel channels, all of which are welded together; common aggregate concrete is poured into the U-shaped steel channels, while recycled aggregate concrete is poured into the round steel pipe; and anti-shear bolts are welded in the U-shaped steel channels. The steel pipe of a large diameter is adopted at the corner of the L-shaped column to restrain the recycled concrete, the stress performance and the anti-torsion capacity of the L-shaped column are improved, and the bearing capacity and the resistance to shock of the recycled concrete restrained by the steel pipe are improved, the doubt of people on poor properties of the recycled concrete is reduced, and the recycled concrete can be well popularized and utilized to high-rise buildings and the building waste can be recycled. The recycled concrete steel pipe L-shaped column is applicable to the high-rise buildings and regions relatively high in seismic intensity, and therefore, the application of the recycled concrete is expanded. Besides, as a covering steel plate and the steel pipe can be used as formworks, the formwork is omitted, the construction speed is increased and the economic benefit is increased.
