Aluminum formwork for high-rise building and construction method of aluminum formwork

The invention discloses an aluminum formwork for a high-rise building and a construction method of the aluminum formwork, and belongs to the technical field of constructions.The aluminum formwork comprises a first aluminum formwork body, and a plurality of second aluminum formwork bodies are arranged on one side of the first aluminum formwork body. According to the aluminum formwork, the multiple vertical reinforcing ribs are fixed to the inner side of the first aluminum formwork and the inner side of the second aluminum formwork, the transverse reinforcing ribs are manually operated to enable spherical rods to enter first clamping grooves formed in the vertical reinforcing ribs, meanwhile, clamping blocks can convey air in elastic air bags into second inner cavities, and when the clamping blocks completely enter the transverse reinforcing ribs, the transverse reinforcing ribs are clamped in the second inner cavities; a first spring can drive a piston to move downwards, gas in a second inner cavity is conveye
