[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 4 shown, in Embodiment 1, a narrow-edge door and window with a common frame border and middle frame 8 includes two symmetrically arranged frame borders 1. A window sash is arranged between the two frame borders 1. The window sash is one or more of an inward-opening glass sash 2, a fixed glass sash, and an outward-opening glass sash 5. The inward-opening glass sash 2, the fixed glass sash, and the outward-opening glass sash 5 are all existing window sashes. Among them, the fixed glass sash can be selected as glass. A middle frame 8 is arranged between two adjacent window sashes. The window sash is installed between the middle frame 8 and the frame border 1 and between the middle frame 8 and the middle frame 8. The window sash can be selected from one or more sash frames, which increases the practicability of the window frame. It is also possible to install any one of the inward-opening glass sash 2, the fixed glass sash, and the outward-opening glass sash 5 between the frame borders 1 and 1 according to the actual requirements of the door and window, improving the versatility of the frame border 1 and the middle frame 8. The frame border 1 and the middle frame 8 have the same structure, reducing the installation difficulty of the window frame. Both the frame border 1 and the middle frame 8 include an inner aluminum profile 101 inside the frame and an outer aluminum profile 103 outside the frame. A heat insulation strip 102 is connected between the inner aluminum profile 101 inside the frame and the outer aluminum profile 103 outside the frame. The heat insulation strip 102 is two symmetrically arranged heat insulation strips 102. One end of the heat insulation strip 102 is snap-connected to the inner aluminum profile 101 inside the frame, and the other end of the heat insulation strip 102 is snap-fitted with the outer aluminum profile 103 outside the frame. The heat insulation strip 102 is a C-shaped heat insulation strip 102. The frame border 1 and the middle frame 8 have the same structure. Furthermore, the outer aluminum profile 103 of the frame border 1 and the outer aluminum profile 103 of the middle frame 8 have the same structure. When the frame border 1 and the middle frame 8 are used in cooperation, the installation difficulty is reduced, and the installation efficiency is also improved.

[0024] In this embodiment, the outdoor side width of the outer-frame aluminum profile 103 is the same as the indoor side width of the inner-frame aluminum profile 101. Since the two side widths are the same, it can be used as an outer-frame profile or a middle mullion profile, with strong applicability. Moreover, the same profile reduces the installation difficulty and thus improves the installation efficiency. There is a cavity inside the outer-frame aluminum profile 103, and symmetrical grooves 104 are provided on the left and right sides of the outer-frame aluminum profile 103. There are two cavities on the inner-frame aluminum profile 101, and two symmetrical grooves 105 are provided on the left and right sides of the inner-frame aluminum profile 101. The grooves 104 and 105 are symmetrically arranged on both sides of the frame 1 or the middle frame 8, facilitating the installation of the corresponding inward-opening glass sash 2, fixed glass sash, and outward-opening glass sash 5, with convenient installation and increased applicability of the frame 1 and the middle frame 8. The outer-frame aluminum profile 103 and the inner-frame aluminum profile 101 have the same width, and the inner-frame aluminum profile 101 and the outer-frame aluminum profile 103 have the same side width, reducing the width of the visible surface. While the visible surface becomes narrower, it can still meet the requirements such as inward-opening sash, outward-opening sash, and adding an electric control module.

[0025] Specifically, both the frame 1 and the middle frame 8 include the inner-frame aluminum profile inside the frame 1, the heat insulation strip 102, and the outer-frame aluminum profile 103. The visible surfaces of the outer-frame aluminum profile 103 and the inner-frame aluminum profile 101 of this frame 1 are of equal width, with a symmetrical structure, and can be used as an outer-frame profile or a middle mullion profile, with stronger applicability. When in use, corresponding hardware slots can be provided on the left and right of the inner-frame aluminum profile 101 and the outer-frame aluminum profile 103 of the frame 1 and the middle frame 8, ensuring that hardware can be installed whether it is inward-opening or outward-opening.
