Description

Technical Field

[0001] The invention belongs to the technical field of door and window production, and particularly relates to a high-performance door and window corner assembly angle code. Background Art

[0002] The reliability and performance of the corner connection of aluminum alloy door and window frames and window sashes are directly related to the physical performance and usage functions of doors and windows. At present, most aluminum alloy door and window systems on the market use aluminum alloy corner brackets as corner connectors. However, Figure 1 and Figure 2 As shown, taking a typical center-hung window as an example, the corner cavities of the center-hung window frame and sash profiles vary in shape. The corner cavity consists of the main cavity body and the protruding cavity connected to it. During use, the aluminum alloy corner brackets do not perfectly match the corner cavity of the profile, resulting in non-contact cavities. This connection method is also prone to deformation, resulting in uneven and loose corners after assembly. Especially for profiles with larger cavities, solid corner brackets waste raw materials, while hollow corner brackets lack sufficient connection strength. In addition, uneven frames and sashes and insufficient corner strength seriously affect the airtightness and watertightness of aluminum alloy doors and windows. If the metal materials are in direct contact, cold bridges will occur, which will also affect the overall thermal performance of the doors and windows. Summary of the Invention

[0003] In response to the above-mentioned technical problems, the present invention provides a high-performance door and window corner combination code, which fits tightly with the corner cavity. While ensuring the connection strength of the combination code, it also avoids the cold bridge problem caused by direct contact between the cavity and the metal material, thereby ensuring the overall thermal performance of the doors and windows.

[0004] The technical solution of the present invention is:

[0005] A high-performance door and window corner assembly angle code includes an inner component, a first outer component and a second outer component, the first outer component is provided with a first placement groove, the second outer component is provided with a second placement groove, the first outer component and the second outer component are connected by upper and lower snaps to form an L-shaped assembly, the outer contour of the assembly is adapted to the shape of the corner cavity, the first placement groove and the second placement groove are located inside the assembly, and the first placement groove and the second placement groove are used to place the inner component.

[0013] The beneficial effects of the present invention are:

[0014] The present invention forms the required corner code by assembling an inner component, a first outer component and a second outer component. The corner code is installed in the corner cavity and locked with screws. The corner code fits tightly with the corner cavity. Then, glue is injected according to the process requirements, which helps to ensure the firmness of the connection and also helps to ensure that the flatness, sealing and other properties of the corner connection meet the requirements.
