Cantilevered floor slab rebar structure adopting steel bar truss formworks and bar reinforcing method

The invention discloses a cantilevered floor slab rebar structure adopting steel bar truss formworks and a bar reinforcing method. The problem that support formworks of a cast-in-place cantilevered reinforced concrete floor slab of an existing high-altitude cantilever floor have support difficulties and are long in construction period and high in construction price is solved. A main building structure (8) is included, a steel beam cantilever frame composed of steel beams (9) parallel to the main building direction and steel beams (10) perpendicular to the main building direction is arranged onthe outer side of the main building structure (8) in an overhang manner, steel beam panels (11) parallel to the main building direction are arranged on the steel beams (9) parallel to the main building direction, and steel beam panels (13) perpendicular to the main building direction are arranged on the steel beams (10) perpendicular to the main building direction, the steel bar truss formworks are fixedly welded to the
