Rotary scaffold and application of rotary scaffold in decoration engineering of building exterior slope-shaped roof

The invention relates to the technical field of building construction and discloses a rotary scaffold and an application of the rotary scaffold in decoration engineering of a building exterior slope-shaped roof. The rotary scaffold comprises a rotary bracket and an L-shaped rotary frame, wherein one arm of the L-shaped rotary frame is hinged to the rotary bracket through a rotary shaft; the tail end of the other arm of the L-shaped rotary frame is connected with an L-shaped connection rod in a telescopic connection mode; a bolt hole is formed in the other end of the L-shaped connection rod. The rotary scaffold is simple and safe in structure, can be assembled on the ground conveniently and also can be assembled on a roof platform of a high-rise building, and later recycling and reusing are also facilitated.
