PURPOSE: A frame coupling structure for a window frame or a door frame is provided to disperse stress caused by loads applied to the window frame or the door frame due to formation of an inclined end and a horizontal end or a vertical end and to prevent distortion in a coupled part against an external force. CONSTITUTION: A frame coupling structure for a window frame or a door frame comprises a frame(100A) with a pair of horizontal frames(10) and a pair of vertical frames(20). The horizontal frame comprises a first inclined end(12) and a first vertical end(15). The vertical frame comprises a second inclined end(22) and a second extension end(23) to be combined with the horizontal frame. |
