s3 paving and pasting of the waterproof and heat-preservation integrated plate: before paving and pasting, the BIM is used for lofting, the proper plate size is determined, the plate is customized and processed, and 50mm overlapping edges are reserved on the four sides of the waterproof coiled material respectively; coating bonding mortar on the inner side of the plate and paving the plate on the leveling layer;
s4 board seam filling: cleaning up sundries in a board seam, then plugging the reserved overlapping edge of a waterproof layer of a board into the board seam, injecting rigid foam polyurethane into the seam, pressing a water-swelling type sealing strip after the polyurethane is completely molded, then sealing the board seam by using elastic waterproof sealant, after the sealant is completely solidified, reinforcing the board seam by using waterproof lining cloth, and flatly pasting and compacting the waterproof lining cloth with the width of 150mm by using waterproof paint;
s5 casting of a protective layer: erecting a template, simultaneously embedding reinforcing steel meshes, pouring C30 fine-stone concrete at one time to form a protective layer without a construction joint, and immediately curing for 14 days by adopting a water film after initial setting.
S6 roof internal corner treatment: scraping an arc-shaped mortar part on an internal corner formed by the roof of the roof building and the waterproof surface layer integrated structure on the inner side of the parapet wall, erecting a template on the outer side of the arc-shaped mortar part, and pouring C30 fine stone concrete to form an additional protection part;
s7 processing the parapet wall top along the external corner: utilize to shield aluminum plate cover above parapet top integrated structure, shield aluminum plate outside the parapet inside and outside both sides turn back downwards, in parapet top integrated structure below with scrape the trapezoidal mortar portion that picture connection parapet inboard facade and shield the aluminum plate kink, trapezoidal mortar portion is to shielding aluminum plate one side slope.
