Method for reinforcing high-rise autoclaved lightweight concrete (ALC) wall through steam pressurization

The invention relates to a high-rise steam pressurization ALC wall reinforcing method which comprises the following steps: step 1, splicing a plurality of ALC wallboards into an ALC wall, and filling and compacting polymer bonding mortar between concave and convex notches of two adjacent ALC wallboards; step 2, filling polymer bonding mortar between the lower end of each ALC wallboard and the bottom beam board, and fixing the ALC wallboards by using partition board U-shaped clamps; the upper end of each ALC wallboard and the beam bottom are reinforced in the same way; 3, the side faces of the ends of the ALC wall plates at the two ends of the ALC wall body, the structural columns and the shear wall are connected in a reinforced mode through galvanized U-shaped clamps and pins; 4, targeted reinforcing measures are set according to the size of the high-rise ALC wall; and 5, holes are formed in the ALC wall body according to design and construction requirements, and the formed holes are reinforced.
