DURABILITY AND UNIT OF MEASURE THAT IMPROVE ASSEMBLY, DESCENT TYPE OF DOOR PANEL

摘要

PURPOSE: An elevating type door panel having improved durability and assemblability is provided to simplify the manufacturing process of the door panel because the door panel is composed of multiple unit members. CONSTITUTION: An elevating type door panel(100) having improved durability and assemblability is formed by extrusion-molding shaping steel members(110). A first connection assembly(101) and a support protrusion(102) are integrally formed on the top of each shaping steel member, and a second connection assembly(103) and a support groove(104) are integrally formed on the bottom thereof. The second connection assemblies and the support grooves are coupled to the first connection assemblies and the support protrusions. Left and right border members(115,116) finish both sides of the shaping steel members.
