Throughout the drawings, like reference numbers indicate identical or functionally identical elements.

Fig. 1 shows a fixing section between an extremely narrow door and window and a building body, in order to improve sealing performance and reduce damage to a waterproof insulation layer 4 of the building body when the window frame 20 is installed, the window frame 20 is fixed by adopting a dry installation mode of matching the auxiliary frame 10.

The subframe 10 serves as a frame of a door opening, and is directly buried in the concrete layer 1 when the building wall is constructed and poured. The sub-frame 10 is provided with a cross member 11 extending toward one side of the concrete layer 1 to enhance the firmness of the sub-frame 10 in the concrete layer 1. This is because the difference in stress at the edge of the concrete layer 1 is large and the stress at the inner side thereof is close to the middle, and there is usually a case where the stress distribution portion is concentrated at the edge, and the middle appears more uniform than the stress distribution at the edge. Therefore, the subframe 10 provided at the edge of the wall is susceptible to stress maldistribution, resulting in a relatively fragile structure and even occurrence of fine cracks at the edge. Since the window frame 20 is fixed to the sub-frame 10 by means of a small fastener, rather than the conventional embodiment using expansion bolts for fixing in the concrete layer 1, the above-described relatively weak or minute crack condition may affect the firmness of the sub-frame 10, thereby causing instability after the window frame 20 is installed. The middle position of the auxiliary frame 10 and the concrete layer 1 is correspondingly connected and fixed through the cross beam 11, so that the firmness of the auxiliary frame 10 is improved.

In particular, the cross beam 11 is actually formed by two bars 11a parallel to each other and extending towards the portion to be treated in the concrete layer 1, each 2 bars 11a forming 1 group, this combined structure finally forming a U-shaped cross beam 11 and being connected to the subframe 10 by means of fasteners at the root, thus facilitating the flexible assembly and manufacture of the subframe 10 and the double bar structure also increasing the contact surface of the cross beam 11 with the concrete layer 1. This beam 11 structure is optimized with the rod body 11a protruding 83mm towards the concrete layer 1. The window frame 20 includes an outer frame 23 and an inner frame 22 facing the outdoor side, and the outer frame 23 and the inner frame 22 are connected by a heat insulating strip 24. For aesthetic design purposes, the thickness of the window frame 20 must be small enough, so that the thickness of the outer frame 23 is 13mm and the thickness of the inner frame 22 is 25 mm. In view of the very small thickness of the outer frame 23, a connection fixing structure between the entire window frame 20 and the sub-frame 10 is disposed on the inner frame 22, which is particularly suitable for fixing the window frame of the inward opening type. This is because the hinge fixing position of the inward opening window is also biased to the indoor side, and the weight of the window or the weight of the outer frame 23 is transmitted to the sub-frame 10 through the inner frame 22, thereby securing the stability. A self-tapping member 21 is provided on the side of the inner frame 22 adjacent to the sub-frame 10, and is connected to the sub-frame 10, and the self-tapping member 21 is an M5 screw. Thus, the subframe 10 is embedded in the wall casting stage. The outer side surface of the auxiliary frame 10 is used as a base line for constructing a waterproof heat-insulating layer 4 on the outer wall surface of a building, a cement mortar layer 2 is constructed on the inner wall surface for leveling, and the wall surface is humidified to pollute the window frame 20. In addition, since the sub-frame 10 is a modularly prefabricated plastic profile, the surface flatness thereof is high, so that the gap between the sub-frame 10 and the window frame 20 is more easily controlled to be 10mm when the window frame is installed, and the sealing and heat insulating properties can be ensured after the soft sealing layer 6 is filled.
