[0001] The utility model relates to the technical field of diving positioning, in particular to a cantilever scaffold with an improved structure. Background Art

[0002] During the construction of a building, a scaffold that unloads the load through a frame structure on a rigid cantilever beam attached to the building structure is required for the operation and safety protection of the main body or decoration project in building construction.

[0003] In the prior art, when the cross beam of the cantilever scaffold is fixed on the floor, only a reinforcement fixture is used to fix the other end of the cross beam.

[0004] However, when the weight on the cantilever scaffold is heavy, it will cause the center of gravity to tilt, resulting in the situation that the reinforcement fixture comes out of the cement floor, causing the cantilever scaffold to tilt and the base to shake. Therefore, the utility model proposes a cantilever scaffold with an improved structure to solve the above problems. Content of the Utility Model

[0007] A lower support plate, a plurality of cross beams are arranged on the lower surface of the lower support plate, and a positioning plate and a plurality of support rods are arranged on the upper surface of the lower support plate.
