Understand the main types, forms, characteristics and applications of aluminum alloy doors and windows, master the structure of window frames and sashes of aluminum alloy sliding windows, master the basic method of determining the size of aluminum alloy, understand the application of hardware and construction machines and tools of aluminum alloy doors and windows, be able to complete the correct installation operation according to the process of aluminum alloy sliding windows, control the construction quality, and correctly implement the finished product protection of aluminum alloy sliding windows,
Due to the characteristics of materials, aluminum alloy casement windows avoid the shortcomings of traditional wooden casement windows, such as easy deformation and durability, and have the characteristics of more lightweight, solid, high performance, easy to form, beautiful and so on. Therefore, their structure, installation process, construction operation and other aspects are very different from wooden casement windows. The aluminum alloy window shown in Figure 4-1 includes the upper fixed window and the lower inward opening casement window. Correctly use machines, tools, hardware, accessories and accessories to complete the installation and fixation of window frames and the assembly of window sashes.
Types and characteristics of aluminum alloycasement windows
Aluminum alloy casement windows have the advantages of large opening area, good ventilation, good sealing, sound insulation, heat preservation and impermeability. Aluminum alloy casement windows are divided into internal casement windows and external casement windows.
The advantage of the inner opening window is that it is convenient to clean the window, but the disadvantage is that the window width is small and the field of vision is not wide. It takes up part of the indoor space when opening, and it is inconvenient to use the screen window. If the sealing quality is not qualified, it may also leak rain. The advantage of the outward opening window is that it does not occupy space when it is opened, but the disadvantage is that it takes up space outside the wall when it is opened, and it is easy to be damaged when there is a strong wind.
In cold areas or rooms with special requirements, double-layer aluminum alloy casement windows are also used. Aluminum alloy double-layer casement windows have different opening methods, commonly used are inner window opening, outer window opening and double-layer both outer opening.
