Overhanging cloud ladder breaking through external wall of high-rise and super high-rise building and construction method thereof

The invention relates to an overhanging cloud ladder breaking through an external wall of a high-rise and super high-rise building. Specific upper and lower corresponding positions of the building areprovided with corresponding upper and lower slide rails, the upper and lower side rails are respectively matched with corresponding telescopic moving cantilevers, and the external wall of the building are provided with openings for the telescopic moving cantilevers extending outwards; the upper and lower telescopic moving cantilevers both extend outwards from the openings along the correspondingsliding rails; a set of overhanging interval pedals is overhangingly arranged below the portion of the upper telescopic moving cantilever extending out of the opening, a soft/hard ladder that can be overhangingly arranged downwards is arranged on the upper telescopic moving cantilever at the front portion of the outermost side of the overhanging interval pedal, the soft/hard ladder extends downwards to the lower telescopic
