[0002] With the aesthetic needs of consumers, currently building doors and windows are beginning to be designed towards the direction of narrow-frame minimalism. Since the doors and windows themselves have a certain weight, especially those with large cross-sectional dimensions and thick glass, how to balance the gravity distribution after reducing the frame material size and how to fix them more quickly and firmly on the window opening have become new problems faced in the industry.

The above description is for the convenience of describing the present utility model and simplifies the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] The singular forms "a", "the", and "said" used in the specification, unless clearly specified otherwise, include the plural forms.

[0019] In the specification, when it is said that an element is "on", "fixed to", "connected to", "joined to", etc. another element, the element can be directly on, fixed to, connected to, joined to, or in contact with the other element, or there may be an intermediate element.

[0020] The exemplary embodiments of the present application will be described below with reference to the drawings. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments. In all the drawings, the same reference numerals represent the same or functionally identical elements.

[0021] Figure 1 It shows the fixed section between the ultra-narrow doors and windows and the building body. In order to improve the sealing performance and reduce the damage to the waterproof and thermal insulation layer 4 of the building body during the installation of the window frame 20, the window frame 20 is fixed by a dry installation method in cooperation with the auxiliary frame 10.

[0022] The auxiliary frame 10 serves as the frame of the door opening and is directly embedded in the concrete layer 1 during the construction and pouring of the building wall. A cross beam 11 extending towards one side of the concrete layer 1 is provided on the auxiliary frame 10 to enhance the firmness of the auxiliary frame 10 in the concrete layer 1. This is because the stress difference between the edge of the concrete layer 1 and the middle position near its inner side is relatively large. Usually, there is a partial concentration of stress distribution at the edge, while the stress distribution at the middle position is more balanced compared to the edge. Therefore, the auxiliary frame 10 provided at the edge of the wall is prone to uneven stress distribution, resulting in relatively fragile structure or even slight cracks at the edge. Since the window frame 20 is fixed to the auxiliary frame 10 by short fasteners instead of being fixed in the concrete layer 1 using expansion bolts in the traditional installation method, the above-mentioned relatively fragile or slight crack situation will affect the firmness of the auxiliary frame 10, and further cause instability after the installation of the window frame 20. By means of the cross beam 11, the auxiliary frame 10 is connected and fixed to the middle position of the concrete layer 1, thus enhancing the firmness of the auxiliary frame 10.

[0023] Specifically, the cross beam 11 is actually composed of two rod bodies 11a that are parallel to each other and extend towards the middle part in the concrete layer 1. Every two rod bodies 11a form a group. This combined structure finally forms a U-shaped cross beam 11 and is connected to the auxiliary frame 10 through fasteners at the root, which is convenient for the flexible assembly and production of the auxiliary frame 10, and the double-rod structure also increases the contact surface between the cross beam 11 and the concrete layer 1. The optimal length for the rod body 11a to extend towards the concrete layer 1 is 83 mm. The window frame 20 includes an outer frame body 23 and an inner frame body 22 facing the outdoor side. The outer frame body 23 and the inner frame body 22 are connected by a heat-insulating strip 24. For the aesthetic requirements in design, the thickness dimension of the window frame 20 must be made small enough. Therefore, the optimal thickness of the outer frame body 23 is 13 mm, and the optimal thickness of the inner frame body 22 is 25 mm. Considering that the thickness of the outer frame body 23 is very small, the connection and fixing structure between the entire window frame 20 and the auxiliary frame 10 is arranged on the inner frame body 22. This fixing structure is particularly suitable for the fixing of inward-opening windows. This is because for inward-opening windows, the hinge fixing position also tends to be on the indoor side. Whether it is the weight of the window or the weight of the outer frame body 23, it is transmitted to the auxiliary frame 10 through the inner frame body 22 to ensure stability. A self-tapping part 21 is provided on the side of the inner frame body 22 adjacent to the auxiliary frame 10 to connect with the auxiliary frame 10, and the self-tapping part 21 selects an M5 screw. Thus, the auxiliary frame 10 is pre-embedded during the wall pouring stage. Using the outer surface of the auxiliary frame 10 as the baseline, a waterproof and heat-insulating layer 4 is constructed on the outer wall of the building, and a cement mortar layer 2 is constructed on the inner wall for leveling, and the wet building materials on the wall surface may pollute the window frame 20. In addition, since the auxiliary frame 10 is a modular prefabricated plastic profile with high surface flatness, when the window frame 20 is installed, the gap between it and the auxiliary frame 10 can be more easily controlled within 10 mm. After filling with a soft sealing layer 6, the sealing and heat-insulating performance can be guaranteed.
