Cantilever building floor steel bar structure adopting steel bar truss template

The utility model discloses a cantilever building floor steel bar structure adopting a steel bar truss formwork. The problems that an existing supporting formwork of a cast-in-place cantilever reinforced concrete floor of a high-altitude cantilever building is difficult to support, long in construction period and high in manufacturing cost are solved. A main building structure (8), 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 on the outer side of the main buildingstructure (8) in a cantilever mode. Parallel main building direction steel beam panels (11) are arranged on the parallel main building direction steel beams (9); a vertical main building direction steel beam panel (13) is arranged on the vertical main building direction steel beam; steel bar truss formworks are fixedly welded to the steel beam cantilever frame, each steel bar truss formwork is composed of a rectangular bo
