The usual roof system design consists of main steel structure, main keel, secondary keel, rock wool, purlin, waterproof layer, T-code fixed support, standing seam roof panel, windproof clamp, etc. For curved roofs with large curvature, it is difficult to arrange keels along the curved surface or it is difficult to ensure a smooth transition of the roof curvature, which affects the architectural shape. Therefore, we invented a standing seam metal roofing system. Summary of the invention

[0009] A standing seam metal roofing system, the construction method of which is as follows: S1: The main keel perpendicular to the curved roof direction is fixed to the main steel structure beam through the adapter. The spacing between the keels is generally not more than 1000mm. The smaller the keel spacing, the gentler the curvature of the roof. The size of the keel connector at each position is determined in advance during the detailed design. S2: Lay a punched corrugated steel base plate on top of the main keel, use stainless steel screws to pierce the steel plate at the overlap position and fix it on the keel, and lay non-woven gauze on the steel base plate as a vapor barrier; S3: Use stainless steel screws to install the T-code fixing bracket on the keel. Rubber anti-corrosion sheets are placed on the bottom of each T-code fixing bracket to prevent the two materials from corroding each other. S4: Lay the thermal insulation rock wool and waterproof membrane, cut out an opening of the length of the support with a blade at the T-code fixed support position and insert it onto the support S5: Put water-swellable waterproofing strips around the intersection of the T-code fixed support and the waterproof layer. The width of the strips is 50mm on each side. Stick butyl tape along the long side of the T-code fixed support. The sticking height should be at least half of the distance from the waterproof layer to the T-code fixed support. The length should be 500mm on each side of the support and folded in half to stick. The bonding width with the waterproof plane should not be less than 500mm.
