Description

Technical Field

[0001] The utility model relates to the technical field of door and window profiles, in particular to a concealed aluminum structure for fastening a sash from an opening. Background Art

[0002] PVC plastic doors and windows are light in weight, have certain thermal insulation properties, and are relatively low in price. Therefore, they occupy an important position in the development of doors and windows, and even occupied a dominant position for a long time. However, due to the rapid aging of PVC plastic itself, the material is brittle under low temperature conditions, and its fire resistance is also poor. It is easy to discolor after a long time of use, affecting the decorative effect of the facade. Aluminum alloy doors and windows are also very common. They are rust-proof, non-fading, and non-shedding. They have fast heat transfer and good fire resistance. They have good facade decorative effects, but their thermal insulation properties are poor. The heat transfer coefficient K value of simple aluminum alloy doors and windows is W / m 2 ·K, which does not meet the lower limit of the national energy-saving requirements.

[0003] Since both have their own advantages and disadvantages, doors and windows made of aluminum alloy composite PVC profiles have also appeared on the market. This type of composite aluminum-plastic door and window combines the advantages of both, with good sealing, thermal insulation performance, and facade decoration effects, and is widely praised in the construction market.

[0004] Since aluminum and PVC are completely different materials, their various physical and mechanical properties are very different. The aluminum-plastic composite methods in the existing technology mostly use clips and / or screws for connection. Providing clips between the aluminum and PVC materials will increase the thickness of the window body, and there will be a gap between the aluminum and PVC materials. The use of screws for connection requires opening mounting holes in the aluminum and / or PVC materials. Both of the above connection methods will affect the sealing and thermal insulation performance of the composite aluminum-plastic doors and windows. Utility Model Content
