[0026] The first aluminum plate surface layer is formed by laying a 2.0 mm thick first aluminum veneer 1 (plain plate) along the inner side of the thermal insulation rock wool 3, and the second aluminum plate surface layer is formed by laying a 2.5 mm thick second aluminum veneer 2 (plain plate) along the outer side of the thermal insulation rock wool 3; the third aluminum veneer 13 is 3 mm thick, and the surface is fluorocarbon sprayed; the first aluminum plate surface layer and the inner waterproof layer are fixedly connected to the L50x4 hot-dip galvanized angle steel 5 by self-drilling nails; the second aluminum plate surface layer and the middle waterproof layer are fixedly connected to the outer side of the 60x60x4 hot-dip galvanized steel square tube 7 by self-drilling nails.

[0027] The three-layer waterproof system includes an outer waterproof layer, an intermediate waterproof layer, and an inner waterproof layer; the outer waterproof layer is arranged on the outer side of the steel structure body, and is composed of multiple 3mm third aluminum veneers 13 (fluorocarbon sprayed) laid along the outer side of the steel structure body, and adjacent third aluminum veneers 13 are fixed by aluminum angle pieces 16 (anodized) and sealed with glue; the intermediate waterproof layer is laid along the surface of the second aluminum plate surface layer, and adopts 3mm thick SBS modified asphalt waterproof membrane and 1mm thick Huiding exposed self-adhesive waterproof membrane 10; the inner waterproof layer is arranged between the thermal insulation rock wool and the first aluminum plate surface layer, and adopts 3mm thick SBS modified asphalt waterproof membrane 2.

[0028] The aluminum angle piece 16 is a U-shaped structure, and the two side surfaces of the U-shaped structure are fixedly connected to the third aluminum single plate 13. The bottom surface of the U-shaped structure is fixedly connected to the outer side of the 60x120x6 hot-dip galvanized steel square tube by st4.8x16 stainless steel self-drilling nails 17. The open side of the U-shaped structure is sealed with glue to form a 12mm thick glue seam 18.

[0029] like Figure 3 , Figure 4 , Figure 5 The multi-layer waterproof system for building curtain wall shown in the figure has 8mm thick aluminum alloy hangers 11 (fluorocarbon spraying) connected to the outside of 60x120x6 hot-dip galvanized steel square tubes at intervals.

[0031] Because the main structure of this project is a steel structure with large deformation, a three-layer drainage system was set up when designing the curtain wall. The first layer of waterproofing is the aluminum plate surface layer (3mm thick) behind the clay brick, which is the first barrier to prevent water infiltration, and the sealant at the joint plays a preliminary waterproofing role. If the glue seam of the first layer of aluminum plate is torn, the second layer of waterproofing is set with 3mm thick SBS modified asphalt waterproofing membrane + 1mm thick Huiding exposed self-adhesive waterproofing membrane on the surface of the second aluminum plate surface, and rainwater can be discharged outward through the surface of the waterproofing membrane.
