House building frame column formwork reinforcing device

The invention discloses a house building frame column formwork reinforcing device. The house building frame column formwork reinforcing device structurally comprises reinforcing pieces, corner protection structures arranged at the corners of the reinforcing pieces and fixing structures used for connecting the two reinforcing pieces. The device has the beneficial effects that according to the arranged right-angle steel plates, fitting and reinforcing of the right-angle steel plates to the frame column formworks can be adjusted according to different sizes of the frame column formworks, corner protection structures are arranged at the inner right-angle positions of the right-angle steel plates in a matched mode, and fitting contact can be conducted on the right-angle positions of the frame column formworks; the problems that when reinforced concrete is poured into the corners of the frame column formwork, downward punching pressure is large, so that the corners of the formwork crack, and reinforcement of the fr
