The externally hung operation steel platform according to claim 1, wherein a scissor brace is arranged between the long main hanging longitudinal beam and the bottom of the platform, an inclined support is arranged between the lateral connecting rod on the outer side and the bottom of the platform, and the middle parts of the two vertical connecting rods on the two ends of the lateral connecting rod on the upper side are provided with lateral middle connecting rods.
10. A method of constructing a plug-in operating steel platform as claimed in any one of claims 1 to 9, comprising the steps of:
working condition one: hoisting the prefabricated side walls on two sides of the prefabricated wall outwards from the middle part into position and completing grouting;
working condition II: when grouting mortar of the prefabricated side walls on two sides reaches design strength, finishing the installation of the externally hung operation steel platform, so that the long main hanging longitudinal beam and the short main hanging longitudinal beam are respectively hung on the corresponding prefabricated side walls;
and (3) working condition III: hoisting the middle externally-raised prefabricated wall in place, grouting, standing on an externally-hung operation steel platform by constructors, installing diagonal braces, wherein the upper ends of the diagonal braces are connected to the side surfaces of the middle externally-raised prefabricated wall, and the lower ends of the diagonal braces are connected to the side surfaces of the prefabricated side walls;
and (4) working condition four: and when the grouting mortar strength of the prefabricated wall with the outwards-raised middle part reaches the design strength, dismantling the diagonal bracing, and finally dismantling the externally-hung operation steel platform.
