Title:
LIFTABLE SCAFFOLD, LIFTING AND INSTALLATION METHODS THEREOF, AND CONSTRUCTION METHOD FOR PREFABRICATED BUILDING
Document Type and Number:
WIPO Patent Application WO/2022/252829
Kind Code:
A1
Abstract:
Disclosed are a liftable scaffold, lifting and installation methods thereof, and a construction method for a prefabricated building. The liftable scaffold comprises: anti-overturning supports, which are disposed on the wall in at least two columns, there being multiple anti-overturning supports in each column longitudinally distributed on the wall; guide rails embedded on the anti-overturning supports in each column, the guide rails ascending or descending relative to the anti-overturning supports; a frame body provided on the guide rails; upper lifting steel beams provided on the wall and located at the upper end of the frame body; lower lifting steel beams provided on the lower end of the frame body, the lower lifting steel beams being arranged corresponding to the upper lifting steel beams; and electric hoists provided on the upper lifting steel beams, suspension wires of the electric hoists being connected to the lower lifting steel beams. The present invention lowers the scaffold lifting difficulty and safety risk, increases construction efficiency, reduces cracks in connection positions between the frame body and a building structure, improves construction quality, and reduces costs.
