Outer-frame-free split-level construction method for wall body at adjacent position of high and low buildings

The invention discloses an outer-frame-free staggered floor construction method for walls at the adjacent positions of high and low buildings, and aims to ensure that at least one floor height difference exists between high buildings and low buildings on the two sides of an expansion joint and no outer frame protection exists. A temporary edge protection structure in a reinforcing mesh form is formed by heightening vertical reinforcing steel bars for stubble throwing on a reinforcing steel bar structure of a first outer wall of a current construction floor of a high-rise building and binding a lower reinforcing steel bar structure of a first outer wall of a next construction floor in advance; a safety rope is arranged on the operation platform on the outer formwork, so that constructors on the operation platform on the outer formwork can bind the safety rope, the high-altitude binding safety of the constructors on the operation platform is ensured, and the safety of high-side edge operation is ensured through
