the zigzag assembly type structure of insulation window frames as well as window and doors

摘要

The present invention relates to a bending-assembled and heat-insulating window frame and a heat-insulating window structure. More particularly, the present invention relates to a window frame bar formed by bending a stainless steel or galvanized material and a bending-assembled heat-insulating window frame assembled at the window, The heat insulating window frame lower bar 120 and the heat insulating window frame side bar 130 are formed by bending the members constituting the heat insulating window frame 100 into the room side and the outdoor side separately A heat insulating window upper bar 200a which constitutes the heat insulating windows 200A and 200B assembled in the heat insulating window frame, a heat insulating window lower bar 200b, The heat insulating window members provided on the indoor side heat insulating window side bar 200e are also bent into the indoor side and the outdoor side separately, and a heat insulating member is provided between the heat insulating window side bar 200c and the heat insulating window side bar 200e, The heat insulating window frame and the heat insulating window are assembled by a welding method to constitute a window frame and a window by a piece assembly such as an aluminum chassis member. It has a high durability and a high rate of indoor and outdoor heat distribution through a window frame and a window frame. Thus, it is a useful invention for providing heat insulation effect, providing high productivity and high productivity, and improving on-site assembly workability.;
