PURPOSE: An opening or closing type window beam supporting member installed at a window frame of a sliding door is provided to maximize thermal insulation, airtightness, and soundproof properties without damaging the drainage function by forming an indirect waterway. CONSTITUTION: An opening or closing type window beam supporting member(3) is installed at a triple rail type window frame. A water hole is individually formed on the right part and the left part of an inner rail and an outer rail, and water is discharged to the outside through a screen rail. The opening or closing type window beam supporting member is installed at the center of the window frame at a lower end of an intersecting point of an inner window and an outer window. An aluminum rail cover(1) is installed to block air flowing to an upper end of the window beam supporting member. |
