Energy-saving door window made of composite material and being of two-channel structure

Abstract

The invention provides an energy-saving door window made of a composite material and being of a two-channel structure. A lock and a hinge are arranged on a door window profile frame, an installation channel of the lock and an installation channel of the hinge are located on the inner side and the outer side of the door window profile frame correspondingly, and the installation channel of the lockand the installation channel of the hinge are non-coaxially arranged. The section length of the door window profile frame, corresponding to the lock position, of the channel on one side of the hinge is smaller than the section length, on one side of the lock, of the door window profile frame, because the widths of the inner side and the outer side of the door window profile frame are consistent, the sectional area, on one side of the hinge, of the door window profile frame becomes small, further the area ratio of the window frame and the door window is decreased, and the door window is more transparent. Meanwhile, the size of the frame is decreased through a small-section profile, further the heat conductivity coefficient of the door window is decreased, and the heat preservation effect ofthe door window is improved; and in addition, compared with a door window profile made of a traditional material, the aspects of the strength, the rigidity, the size shrinkage rate, the linear expansion coefficient, the chemical resistance, fire prevention, the weight and the like of the door window profile made of the composite material are greatly improved.

Description

technical field [0001] The invention relates to a door and window structure, in particular to an energy-saving door and window with a double-channel structure composite material. Background technique [0002] The development of doors and windows in my country has mainly gone through stages such as wooden doors and windows, steel doors and windows, aluminum alloy doors and windows, and plastic steel doors and windows. During the transformation process of each stage, the transformation of door and window materials has become the key to leading the transformation of doors and windows. However, materials such as wood, steel structure, aluminum alloy and plastic steel of traditional doors and windows are not only unsatisfactory in terms of strength, stiffness, dimensional shrinkage, expansion coefficient, chemical resistance, fire resistance and weight, but also have poor thermal insulation performance. It needs to be improved. [0003] In addition, the structure of traditional ...

However, materials such as wood, steel structure, aluminum alloy and plastic steel of traditional doors and windows are not only unsatisfactory in terms of strength, stiffness, dimensional shrinkage, expansion coefficient, chemical resistance, fire resistance and weight, but also have poor thermal insulation performance. needs to be improved

[0003] In addition, the structure of traditional doors and windows such as figure 1 As shown, among them, the installation channel of lock 1 and the installation channel of hinge 2 are on the same channel A. Since the length of the lock is generally greater than 42mm, this results in that the section length of the profile at the installation position of lock 1 must be greater than 42mm to meet the requirements of the lock. Installation requirements, therefore, due to the large cross-section of traditional doors and windows, the area ratio of the door, window, window frame and window becomes larger, which makes the thermal insulation performance and permeability of the doors and windows poor.
