The present invention relates to a project window system with a reinforced chamfered part. A frame fixing screw is coupled to a window frame insulating part to which a pair of frames are connected, and a chamfered coupling screw is coupled to a window supporting part, to which a pair of frames are connected, in the perpendicular direction to the frame fixing screw. Therefore, the frame fixing screw and the chamfered coupling screw are coupled to a joint part of the window frame at right angles to each other, and especially, because the joint part of the window supporting part to which a load of the window is transferred is firmly fixed by the chamfered coupling screw, the joint part of the frame is not widened. |
