The stringing matters are conducted according to the local lines and benchmark points based on civil engineering theories; the design of the exterior aluminum-plastic panel cladding is based on the building's axis. The aluminum-plastic panel frame is formed by the corrected components, with the vertical members' position lines first marked, followed by the determination of the anchoring points of the vertical members.
The robust adjacent parts are securely mounted on the foundation of the laying process, with the adjacent parts being firmly welded using electric welding. Two coats of anti-rust paint are applied to the welds. The adjacent parts are robustly welded to the pre-buried parts on the main structure. In cases where no pre-buried iron parts are installed on the main structure, holes can be drilled and shortened bolts placed to securely attach the adjacent iron parts.
Welding Techniques for Installing Skeleton Frames: Ensure regular checks for elevation, local line positioning, and simultaneously apply anti-rust paint to adjacent welds in cross-sections. Strengthen adjacent components with concealed inspection records, including weld length, thickness, buried elevation, quantity, and insertion depth.
The exterior aluminum-plastic panels are installed on the profile racks, with the screw holes pre-drilled first, and the panels are securely fastened to the steel frame with rivets. The gap between panels is 10-15mm, followed by the injection of silicone weatherproof sealant. It is strictly prohibited to remove the packaging paper before the installation of the exterior aluminum-plastic panels, until the completion when the protective film is peeled off.
