Nacelle-moving construction method for wide span and big area suspended ceiling

The invention discloses a movable nacelle type construction method for a wide-span and larger-width suspended ceiling. The construction method is characterized in that a steel wire rope is tied between top booms on trusses on the adjacent axial lines of a wide-span and larger-width suspended ceiling, a movable nacelle is hung on the steel wire rope to be used as the operating platform of a builder, and a rope is connected with the nacelle to be used for towing and moving the nacelle; then, a pulley is arranged in the position of the web member of the top boom of the truss, a ceiling tile is suspended on the installation position through the pulley, and the builder in the nacelle can instal and fix the ceiling tile. By adopting the construction method, a large mount of material turnover cost can be saved, the construction cost is effectively saved, by adopting the multipoint operation, the construction progress can be accelerated, the construction period can be reduced, the integral work efficiency can be improved, the normal operation of the surface work is guaranteed, the human resource and materials and equipment resources are saved well, and good economic benefit is achieved.
