Description

Technical Field

[0001] The present application relates to the technical field of door and window structures, and in particular discloses a high-sealing expansion frame for doors and windows. Background Art

[0002] Generally speaking, doors and windows are composed of an aluminum door and window frame fixed to a building, and a door and window sash slidably installed on the door and window frame. The door and window sash is composed of a door and window sash body and an aluminum door and window sash frame surrounding the door and window sash body.

[0003] Aluminum alloy system doors and windows are high-end doors and windows that have been upgraded and developed in recent years. Especially in the actual application of replacing old doors and windows with new ones in recent years, most of them are aluminum alloy system doors and windows. Different users have different openings, and one or several sides around the window frame may always encounter one of the following situations:

[0004] 1. The indoor windowsill is too high;

[0005] 2. Extra-thick indoor window covers (even decorative panel window covers with wooden keels);

[0006] 3. Different ceilings in the room block the upper part of the windows;

[0007] 4. After the curtain box is installed indoors, the window sash cannot be opened, etc.

[0008] However, according to the construction practice in the industry, after the owner replaces the window, the glass pressure line must be exposed on all sides of the window (the indoor glue must not touch the glass pressure line, otherwise it will affect the future glass maintenance). At the same time, the gap of the sealant on the outside of the window frame should not be too large, and the maximum should be controlled to no more than 15mm to prevent frequent rework due to leaks in the future! This requires: the visible surface of the frame around a certain finished window we customize for the user is not "equal width"! In view of the above situation, how to achieve "unequal width" window frames on the visible surface, the traditional existing door and window profiles are obviously unable to meet the requirements.

DETAILED DESCRIPTION

[0030] The following is combined with Figure 1 and attached Figure 2 This application is described in further detail.

[0031] The present application embodiment discloses a high-sealing expansion frame for doors and windows. Figure 1 and Figure 2A high-sealing expansion frame for doors and windows includes an expansion frame body 1, a first connecting profile 2, a sealing column 3, a sealing strip 4 and a first heat-insulating profile 5. The expansion frame body 1 is installed outside the window frame 100. The sealing column 3 and the sealing strip 4 are located between the window frame 100 and the expansion frame body 1.

[0032] Reference Figure 1 and Figure 2 , two first connecting profiles 2 are provided, and the two first connecting profiles 2 are respectively connected to the two opposite sides of the side of the expansion frame body 1 close to the window frame 100, and the first connecting profile 2 is integrally formed with the expansion frame body 1. The first connecting profile 2 is bent and formed with a card slot 21 and a sealing slot 22 on the side away from the expansion frame body 1. The sealing slot 22 is located inside the card slot 21. A sealing column 3 is installed in the sealing slot 22. The window frame 100 is integrally formed with two second connecting profiles 101 corresponding to the position of the first connecting profile 2 on the two opposite sides of the side of the expansion frame body 1. The second connecting profile 101 is integrally formed with a first card plate 102 that matches the card slot 21 on the side away from the window frame 100. After the expansion frame body 1 is installed on the window frame 100, the first card plate 102 is clamped in the card slot 21. By installing or removing the expansion frame on the outside of the window frame 100, the door and window can be more adapted to different installation or use environments. At the same time, after the first clamping plate 102 is clamped into the clamping groove 21 , the first clamping plate 102 can squeeze the sealing column 3 in the sealing groove 22 , thereby improving the connection sealing performance between the window frame 100 and the expansion frame.

[0033] Reference Figure 1 and Figure 2 The sealing strip 4 includes a sealing strip body 41 and a mounting strip 42. The sealing strip body 41 and the mounting strip 42 are integrally formed, and the sealing strip 4 is made of rubber. The first thermal insulation profile 5 is snap-fitted and fixed in the middle position of the expansion frame body 1, and two L-shaped profiles are fixed on both sides of the first thermal insulation profile 5, and the two L-shaped profiles are arranged opposite to each other to form a mounting groove. Before installing the expansion frame body 1, first insert the mounting strip 42 into the mounting groove so that the mounting strip 42 will not move laterally, thereby improving the accuracy of the installation of the sealing strip 4. The first thermal insulation profile 5 is made of nylon, which improves the thermal insulation performance of the expansion frame.

[0034] Reference Figure 1 and Figure 2 Two second heat-insulating profiles 103 are fixedly connected in the middle of the window frame 100, and the space between the two second heat-insulating profiles 103 is filled with foam. After the expansion frame is installed on the window frame 100, the sealing strip body 41 abuts against the outer side of one of the second heat-insulating profiles 103, so that the sealing strip 4 is squeezed and deformed, which improves the sealing performance of the connection between the window frame 100 and the expansion frame. The second heat-insulating profile 103 is made of nylon, which improves the heat-insulating performance of the window frame.

[0035] Reference Figure 1 and Figure 2 , a third connecting profile and a second cardboard are provided on the side of the expansion frame body 1 away from the window frame 100. The third connecting profile has the same structure as the second connecting profile 101. The second cardboard has the same structure as the first cardboard 102. Multiple expansion frames can be installed under the window frame 100, which increases the bottom height of the window frame 100 and further reduces the amount of foam glue or sealant used.

[0036] The implementation principle of a high-sealing extension frame for doors and windows in the embodiment of the present application is as follows: when the height of the indoor window sill is too high or the indoor window cover is super thick, multiple extension frames are installed at the bottom of the window frame 100, which increases the bottom height of the window frame 100, reduces the amount of foam glue and sealant used, and increases the installation speed. When different indoor ceilings block the upper part of the window or the window sash cannot be opened after the curtain box is installed indoors, the extension frame connected to the window frame 100 is disassembled to reduce the height of the doors and windows and reduce damage to the doors and windows and windowsills. At the same time, the provision of the sealing column 3 and the sealing strip 4 improves the connection sealing of the window frame 100 and the extension frame.

[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
