The invention discloses a buckling-strip-type aluminum plate curtain wall and an installation method thereof. The buckling-strip-type aluminum plate curtain wall comprises a stand column and a transverse beam fixed between the adjacent lateral sides of the stand column, a waterproof aluminum plate is fixedly arranged on the outer lateral side of the stand column and the outer lateral side of the transverse beam, and heat preservation cotton is arranged on the inner side of the waterproof aluminum plate; a horizontal keel is fixedly arranged on the outer lateral side of the transverse beam and comprises a fixed part and an adjusting part; the fixed part is fixed onto the lateral side of the transverse beam through a bolt, and the adjusting part is in an inverse-C shape and has an outwards-protruding curved surface; a honeycomb composite aluminum plate is arranged on the outer side of the adjusting part, U-shaped folded edges are arranged on the two sides of the honeycomb composite aluminum plate, and a vertical keel is arranged between the adjacent folded edges of the honeycomb composite aluminum plate; a screw groove is formed in the middle of the inner side of the vertical keel, and pressing plates are arranged on the two sides of the screw groove; the screw groove is fixedly connected with the adjusting part through a fixing screw, and the two pressing plates are inserted into the adjacent folded edges of the honeycomb composite aluminum plate respectively and tightly press the folded edges to the outer lateral side of the adjusting part. According to the buckling-strip-type aluminum plate curtain wall and the installation method, installation is easy, a special-shaped building facade can be adapted, and the appearance is attractive.
