Fold Forming for Architectural Copper Facades
折叠成型在建筑铜幕墙的应用
标签：建筑幕墙, 铜板, 立面肌理, 折叠应用
某文化馆铜幕墙（1200 m²，0.8 mm T2 铜）以 45° 线折叠单元批量生产立面肌理板，单板 600×1200 mm、折叠深度 8–15 mm 形成明暗渐变。工厂用数控折弯机预折主线、手工整形次级曲线；折叠板刚度提升，背后无需龙骨加密，节省支架 20%。折叠方向与雨水流向一致设计，兼具导水与自洁功能；表面预钝化后安装。
A 1,200 m² cultural-center facade used 45° line-folded units (0.8 mm T2 copper, 600×1200 mm panels, 8–15 mm fold depth) for a light-gradient skin. CNC brake folding set the primary lines with hand shaping for secondary curves; folding stiffened the panels so sub-framing dropped 20%. Folds run with the rain path for drainage and self-cleaning; panels were pre-patinated before install. ---
