Description

Technical Field

[0001] The present invention belongs to the technical field of aluminum alloy thermal insulation window systems, and in particular relates to a window opening and reversing-free door and window system. Background Art

[0002] With the development of the economy and society, people have increasingly demanded higher energy efficiency in buildings. In particular, the recent market demands for green buildings, energy conservation, carbon peak, and carbon neutrality have placed higher demands on aluminum alloy thermal insulation windows and doors in buildings, leading to their increasing adoption. The aluminum alloy thermal insulation window system consists of three components: an indoor section, a thermal insulation strip, and an outdoor section, made of customized aluminum alloy profiles connected by nylon thermal insulation strips. The indoor and outdoor sections of the aluminum alloy have a high heat transfer coefficient, while the low-contagion non-metallic nylon material separates them, blocking heat conduction. The composite profiles offer excellent properties such as high strength, low heat transfer coefficient, and excellent weather resistance.

[0003] At present, traditional aluminum alloy thermal insulation windows are relatively solid and complicated due to their structure. Especially when a closed window assembly and an outward-opening window assembly are both present in one thermal insulation window, the window frame is often complicated to splice, with serious material waste and a heavy visual effect. The application has certain limitations and the performance is poor. In order to ensure the use function of the traditional thermal insulation window system, the stop of the thermal insulation window frame is on the outdoor side, and the glass pressure line (buckle) needs to be installed on the indoor side to press the glass, resulting in the stop direction of the frame around the thermal insulation window being fixed. If the opening window assembly is set as an inward-opening window, it is consistent with the direction of the window frame stop, which is more convenient to set. If an outward-opening window is used, the window frame stop conflicts with the opening direction, and a turning frame must be set to achieve outward opening, which increases the amount of profiles used. Moreover, because of the addition of the turning frame, the area occupied by the window frame increases, affecting the lighting performance. In view of this, the present solution was created. Summary of the Invention

[0042] The side of the closing window assembly 4 away from the opening window assembly 5 is engaged with the card interface 101 of the first extension section 22 of the frame through-opening profile 1 and the frame stop profile 2. Specifically, the card interface 101 of the first extension section 22 is connected to the outside of the window glass 9 via the EPDM outer rubber strip 6. The frame stop profile 2 is located on the outside. The closing window assembly 4 includes the window glass 9 and two buckle strips 41. The two buckle strips 41 are connected to both sides of the inward side of the window glass 9. The buckle strips 41 have two first locking pins facing each other. The two first locking pins are respectively engaged with the card interface 101 of the first locking protrusion 11 and the card interface 101 of the second locking protrusion 12. The two buckle strips 41 are connected to both sides of the same surface of the window glass 9 and the opening window inner frame 51. An EPDM inner rubber strip 8 is provided between the buckle strips 41 and the window glass 9.

[0043] The side of the opening window assembly 5 away from the opening window assembly 5 is snapped into engagement with the snap interface 101 of the first extension section 22 of the frame opening profile 1 and the frame stop profile 2. The frame opening profile 1 is located on the outside, the frame stop profile 2 is located on the inside, and the first extension section 22 of the frame stop profile 2 extends toward the opening window assembly 5. Specifically, the opening window assembly 5 includes two opening window inner frames 51, two opening window outer frames 52, window glass 9 and two buckle strips 41. The two opening window outer frames 52 are connected to one side of the window glass 9. On both sides, two opening window inner frames 51 are located on either side of the other side of the window glass 9; two buckle strips 41 are connected to the two sides of the window glass 9 on the same side as the opening window inner frames 51. An EPDM inner rubber strip 8 is provided between the buckle strip 41 and the window glass 9. The two opening window inner frames 51 are clamped to the two buckle strips 41 on one side facing each other. The other ends of the two opening window inner frames 51 are clamped to the first extension section 22 of the frame stop profile 2. An outer rubber strip is provided between the opening window inner frames 51 and the first extension section 22 of the frame stop profile 2. The buckle strip 41 has two first locking pins facing each other, which are clamped to the opening window inner frames 51. Specifically, the outer frame 52 of the opening window has protruding ends on both sides of one end facing outward. One protruding end of one opening window outer frame 52 is connected to the outer surface of the frame stop profile 2, and the other protruding end is connected to the window glass 9. An EPDM outer rubber strip 6 is provided between the protruding end and the window glass 9. Another protruding end of the outer frame 52 of the opening window is connected to the surface of the frame opening profile 1, and an outer rubber strip is provided between the protruding end and the frame opening profile. The other protruding end of the opening window outer frame 52 is connected to the window glass 9, and an EPDM outer rubber strip 6 is provided between the protruding end and the window glass 9. In this embodiment, thermal insulation strips 10 made of nylon are connected between adjacent frame opening profiles 1 and frame stop profiles 2, between two adjacent frame stop profiles 2, and between the opening window inner frame 51 and the opening window outer frame 52.

[0044] A locking assembly 102 is provided on the opening window outer frame 52 of the opening window assembly 5 away from the closing window assembly 4. The locking assembly 102 adopts the locking assembly 102 (including a lock block and a lock) commonly used in the existing door and window system, which will not be repeated here, and a handle 103 is provided on the surface of the opening window inner frame 51 close to the locking assembly 102.

[0045] This embodiment also provides a method for manufacturing and installing a window opening and reversing-free door and window system as follows:

[0046] S1, the frame through-opening profile 1 and the frame stop profile 2 are centrally processed in the factory processing area according to the drawing dimensions. The frame through-opening profile 1 and the frame stop profile 2 are beveled at 45°. The two adjacent horizontal and vertical frame through-opening profiles 1 and the frame stop profile 2 or the frame stop profile 2 and the frame stop profile 2 are docked at 45°. When docking, at the corners where each type of profile is docked, there are corner cores (that is, docking interfaces) that match the size of the profile cavity (the docking position of the open window inner frame 51, the open window outer frame 52 and the buckle strip 41).

[0047] When assembling the S2 and closed window components 4, the stop profile is placed on the exterior side and the opening profile is placed on the interior side. This ensures that the glass can be pushed in through the opening on the interior side and then secured by pressing the window glass 9 with the buckle strip 41. During installation, custom EPDM outer rubber strips 6 and glass spacers are used to seal and limit the gaps.

[0048] S3. When assembling the opening window assembly 5, the frame opening profile 1 is positioned outdoors, while the frame stop profile 2 is positioned indoors. This allows the window assembly 5 to be flipped over and used from the outside, utilizing the side frames of the closed window assembly 4. Ensuring that the frame stop profile 2 is positioned indoors ensures that the opening window assembly 5 opens outward. The window glass 9 of the opening window assembly 5 can be pushed into place from the indoor side through the aluminum alloy opening of the opening window assembly 5, where it is then secured by the buckle strip 41 of the opening window assembly 5. During installation, custom EPDM outer rubber strips 6 and glass spacers are used for caulking and positioning.

[0049] S4. At the upper and lower frame positions of the window, the closed window assembly 4 and the open window assembly 5 intersect at the middle support position, and the closed window assembly 4 and the open window assembly 5 are connected with the frame through-hole profile 1 and the frame stop profile 2. The connection method is the internal plug-in corner core connection (insertion into the docking port), and the connection method is the same. The inner and outer sides of the frame through-hole profile 1 and the frame stop profile 2 on both sides of the closed window assembly 4 and the open window assembly 5 are opposite.

[0050] Through the above combination, the door and window system is assembled in an orderly manner. The outward-opening window assembly 5 is also assembled in the factory and then connected and fixed to the frame opening profile 1 and the frame stop profile 2 using hardware to ensure smooth opening and a good seal. The overall assembly of the door and window system is completed.

[0051] During installation, the assembled door and window system will be installed in the designated opening of the civil structure, and the connections will be firmly fixed and well sealed. The installation is completed once it passes the inspection.

[0052] Example 2

[0053] like Figure 4-Figure 5 and Figure 6-Figure 8 As shown, the difference between this embodiment and embodiment 1 is that, Figure 6 As shown, Figure 6 The direction of the middle arrow is the opening direction. The opening window assembly 5 in this embodiment is an inward-opening type. A window opening and reversing-free door and window system also includes a stop profile 3 in the middle of the frame.

[0054] The closed window assembly 4 and the open window assembly 5 are connected through the frame through-hole profile 1 and the middle stop profile 3 of the frame. The card interfaces 101 of the two second extension sections 31 of the middle stop profile 3 of the frame are respectively carded with the open window assembly 5 and the closed window assembly 4. Specifically, an EPDM outer rubber strip 6 is provided between the second extension section 31 of the middle stop profile 3 of the frame and the window glass 9 of the closed window assembly 4, and an opening rubber strip 7 is provided between the second extension section 31 of the middle stop profile 3 of the frame and the opening window inner frame 51 of the opening window assembly 5. The card interfaces 101 of the first card protrusions 11 on both sides of the inner frame through-hole profile 1 are respectively carded with the open window assembly 5 and the closed window assembly 4. Specifically, the card interface 101 of one first card protrusion 11 is connected to the buckle strip 41, and the opening rubber strip 7 is provided between the card interface 101 of the other first card protrusion 11 and the opening window outer frame 52.

[0055] The frame opening profile 1 and the frame stop profile 2 connected on one side of the closed window assembly 4 and the open window assembly 5 are arranged inside and outside. The two open window inner frames 51 of the open window assembly 5 are located on the outside, and the two open window outer frames 52 are located on the inside.

[0056] The manufacturing method and installation method of this embodiment are the same as those of embodiment 1. The only difference is that an additional stop profile 3 in the middle of the frame is manufactured and installed accordingly, which will not be described in detail here.

[0057] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
