Description

Technical Field

[0001] This utility model belongs to the technical field of aluminum alloy thermal insulation window systems, specifically relating to a window system that does not require reversing the window opening direction. Background Technology

[0002] With economic and social development, people have increasingly higher requirements for building energy conservation. Especially in recent years, the market demand for green buildings, energy conservation, carbon peaking, and carbon neutrality has placed higher demands on aluminum alloy thermally broken windows, leading to their widespread adoption. The aluminum alloy thermally broken window system consists of three parts: an interior section, the thermal break strip, and an exterior section, connected by customized aluminum alloy profiles and nylon thermal break strips. The aluminum alloy metal on both the interior and exterior sides has a high heat transfer coefficient, which is separated by nylon, a non-metallic material with a low heat transfer coefficient, thus blocking heat conduction. The composite profile possesses many excellent properties such as high strength, low heat transfer coefficient, and good weather resistance.

[0003] Currently, traditional aluminum alloy thermally broken windows suffer from a rigid and cumbersome structure, especially when both closing and outward-opening window components are present in a single window. This often results in complex frame splicing, significant material waste, a heavy visual appearance, and limited application, leading to poor performance. To ensure functionality, traditional thermally broken window systems have the frame's stop edge on the exterior side, while the glass retaining strip (fastening strip) must be installed on the interior side to secure the glass. This results in a fixed orientation of the frame's stop edge. If the opening window component is set as an inward-opening window, it aligns with the frame's stop edge direction, which is convenient. However, if an outward-opening window is used, the frame's stop edge conflicts with the opening direction, necessitating a steering frame to achieve outward opening. This increases the amount of profile used and, due to the steering frame, the window frame's footprint increases, affecting lighting performance. Therefore, this solution was developed. Utility Model Content

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. This utility model provides a window system with no reversible window opening. When an outward-opening window is required, the closing window assembly and the opening window assembly are connected by two frame stop profiles. The snap-fit ​​interface of the first extension of the outer frame stop profile engages with the closing window assembly, and the snap-fit ​​interface of the first extension of the inner frame stop profile engages with the opening window assembly. When an inward-opening window is required, the closing window assembly and the opening window assembly are connected by a frame through profile and a frame middle stop profile.

The locking interfaces of the first and second locking protrusions on both sides of the inner frame through-hole profile engage with the opening window assembly and the closing window assembly, respectively. Compared with the existing door and window systems, it is not necessary to set a turning frame between the closing window assembly and the opening window assembly to achieve outward opening windows. Moreover, the outer contours, groove shapes and positions, and cavity dimensions of the various profiles in this solution are the same, and the doors and windows can be seamlessly connected and combined, which greatly improves the versatility of the process.

[0024] 2. Due to the flexible and unified design of the profiles, inner frame, and outer frame of the operable window, flexible switching between inward and outward opening of windows can be achieved without being restricted by traditional measures that require the addition of a turning frame, which would increase material usage, reduce effectiveness, and sacrifice effective ventilation area.

[0025] 3. This system achieves uniformity in the profiles used for inward and outward opening windows, resulting in good economic benefits (saving on turn frame materials) and social benefits (because the overall door and window system has a significantly reduced cross-sectional width, thus better reducing energy consumption).

[0026] 4. Compared to the traditional combination of a closed window assembly and an inward-opening sash, this solution has a wider range of applications. The closed window assembly and the openable window assembly can be seamlessly combined with either inward-opening or outward-opening windows without adding a turning frame. Due to the reduction in the number of frames, the waterproof, windproof, and airtight functions of the doors and windows are better improved. Attached Figure Description

A handle 103 is provided on the surface of the inner frame 51 of the opening window near the locking component 102.

[0045] This embodiment also provides a method for manufacturing and installing a window and door system that does not require reversing the window orientation, as follows:

[0046] S1. The frame through profile 1 and the frame stop profile 2 are processed centrally in the factory processing area according to the dimensions in the drawings. The frame through profile 1 and the frame stop profile 2 are treated with a 45° bevel. Adjacent horizontal and vertical frame through profile 1 and frame stop profile 2 or frame stop profile 2 and frame stop profile 2 are butted at a 45° angle. When butting, at the corner of the butt joint of each type of profile, a corner core (that is, the jointing position) matching the size of the profile cavity (the butt joint position of the inner frame 51 of the opening window, the outer frame 52 of the opening window and the fastener 41) is provided.

[0047] S2. When assembling the four-part closed window assembly, a combination of a stop profile on the exterior side and a through profile on the interior side is used. This ensures that the glass can be pushed in and installed from the interior side through the through, and then the window glass 9 is connected and fixed by a fastener strip 41. During installation, a custom-made EPDM outer rubber strip 6 and glass spacers are used for sealing and limiting the gaps.

[0048] S3. When assembling the operable window assembly 5, the frame through-type profile 1 is on the exterior side, and the frame stop-type profile 2 is on the interior side. This utilizes the side frame of the closing window assembly 4, and the operable window assembly 5 is flipped outwards. Ensuring that the frame stop-type profile 2 is on the interior side guarantees that the operable window assembly 5 opens outwards. The window glass 9 of the operable window assembly 5 can be pushed in and installed from the interior side through the aluminum alloy through-type profile of the operable window assembly 5, and then secured by the fastener strip 41 of the operable window assembly 5. During installation, a custom-made EPDM outer rubber strip 6 and a glass pad are used for sealing and limiting.

[0049] S4. At the top and bottom edges of the window, the closing window assembly 4 and the opening window assembly 5 meet at the middle mullion position, and the closing window assembly 4 and the opening window assembly 5 are connected to the frame through profile 1 and the frame stop profile 2. The connection method is the same for both: internal corner core connection (insertion interface). The inner and outer sides of the frame through profile 1 and the frame stop profile 2 on both sides of the closing window assembly 4 and the opening 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 through-mouth profile 1 and frame stop profile 2 by hardware to ensure smooth opening and good sealing. The overall assembly of the door and window system is completed.

[0051] During installation, the assembled door and window system is placed into the designated opening in the civil structure, and the connection and fixation are secure, the seal is good, and the installation is completed once the inspection is passed.

In this embodiment, the opening window component 5 is an inward opening type. A window opening system that does not require reversing the direction of opening 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 by the frame through-hole profile 1 and the frame middle stop profile 3. The two second extension sections 31 of the frame middle stop profile 3 located on the outer side have their locking interfaces 101 engaged with the open window assembly 5 and the closed window assembly 4 respectively. Specifically, an EPDM outer rubber strip 6 is provided between the second extension section 31 of the frame middle stop profile 3 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 frame middle stop profile 3 and the inner frame 51 of the open window assembly 5. The locking interfaces 101 of the first locking protrusions 11 on both sides of the frame through-hole profile 1 located on the inner side are engaged with the open window assembly 5 and the closed window assembly 4 respectively. Specifically, one locking interface 101 of the first locking protrusion 11 is connected to the buckle strip 41, and the other locking interface 101 of the first locking protrusion 11 is provided with an opening rubber strip 7 between the connection of the outer frame 52 of the open window.

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

[0056] This embodiment is the same as the one in terms of manufacturing and installation methods as that in embodiment 1. The only difference is that an additional frame center stop profile 3 is manufactured and installed accordingly, which will not be described in detail here.
