MANUFACTURING METHOD OF ALUMINUM MULTIPLE WINDOW

摘要

The present invention relates to a method for manufacturing an aluminum multiple window. The method for manufacturing an aluminum multiple window comprises: a raw sheet V-shaped groove formation step (S10) of cutting a predetermined portion of a first cover (11), a plurality of rails (12), and a second cover (13) to form a V-shaped groove (110); a window frame formation step (S20) of forming the V-shaped groove (110) of a raw sheet (10) toward the inside of a window frame (100); a V-shaped protrusion formation step (S30) of forming a V-shaped protrusion of a middle frame (200); a middle frame coupling step (S40) of coupling the V-shaped protrusion (210) to the V-shaped groove (110) and coupling the V-shaped protrusion (210) to the V-shaped groove (110); and a window frame installation step (S50).
