Transformation construction method of super high-rise building with crabapple angle

The transformation construction method of the super high-rise building with the crabapple angle belongs to the technical field of building transformation, and comprises the following steps: firstly, supplementing a structure of the crabapple angle position, and meanwhile, welding a newly added inclined outer frame column on the inner side of an original vertical outer frame column on one side opposite to the crabapple angle to form an inner receiving layer; newly-added vertical outer frame columns are constructed on the tops of the newly-added inclined outer frame columns and the tops of the upper inclined columns; then the davit is dismantled; the original roof truss is dismantled; the supporting column is dismantled; and finally, a new roof truss is installed, and the original vertical outer frame columns on the outer sides of the newly-added vertical outer frame columns and the original vertical outer frame columns on the outer sides of the newly-added inclined outer frame columns are dismantled.
