The invention discloses a method for construction of a stiff skeleton and banding of tower column rebars. The stiff skeleton comprises a rectangular truss-structured skeleton body, main rebar positioning plates are fixed to the top end, the bottom end, the front outer side and the rear outer side of the skeleton body respectively, each main rebar positioning plate is horizontally placed and provided with open grooves on the outer end face which are used for positioning main rebars, the tower column main rebars are respectively disposed in the open grooves on the upper main rebar positioning plate and the lower main rebar positioning plate on the same side, and the main rebars are banded to the skeleton body. The tower column main rebars can be placed in the open grooves on the main rebar positioning plates to be banded to the skeleton body, so that horizontal positioning of the tower column main rebars can be controlled effectively, and horizontal positioning accuracy of the tower column main rebars in banding can be improved greatly. In addition, the tower column main rebars are banded on the field ground and integrally hosted for butt joint, so that aerial binding is avoided, and construction progress of a bridge main tower is quickened.
