Aluminum alloy doors and windows in our daily life more and more common, but there are still many people do not understand its main materials and installation methods, let's have a look at it!
1、 Aluminum alloy profile
The mechanical properties, dimensional deviation, chemical composition and supply status of profiles used for aluminum alloy doors and windows shall comply with the relevant provisions of the current national standard "aluminum alloy building profiles Part 1 - base materials" gb5237.1. The section size deviation of profiles is generally of high precision. The wall thickness of the main stressed profile shall be determined by structural calculation, but the minimum wall thickness of the stressed profile is required in the specification: the minimum measured wall thickness of the main stressed part of the profile for door shall not be less than 2.0 mm, the minimum measured wall thickness of the substrate at the main stressed part of the profile for window shall not be less than 1.4 mm, and other properties of aluminum material, such as surface treatment, shall meet the requirements of national standards.
The glass shall comply with the requirements of structure and energy saving, and meet the requirements of the current national specifications. It should be noted here that when the altitude difference between the production area and the place of use of insulating glass is more than 800 meters, stainless steel capillary suction pipe should be installed and sealed after the pressure of the installation and use area is balanced.
3、 Hardware accessories
Hardware accessories are the key accessories that affect the function of doors and windows, and play an important role in the water tightness of doors and windows.
4、 Main stress parts of profile section
In understanding the code, the main stress part refers to the web, flange or other fixed components in the main profile section of aluminum alloy doors and windows bearing vertical and horizontal load.
5、 Installation mode
There are two main ways to install doors and windows
1. Dry installation
The additional metal frame is pre installed at the door and window opening, so that the wall gap can be filled and waterproof treatment can be carried out in advance. After completion, the window frame is fixed on the steel frame. This installation method is mainly used for high-grade doors and windows such as system doors and windows.
2. Wet installation
Aluminum alloy doors and windows are directly installed in the wall openings without surface treatment. After the door and window frames are installed, the gap between the door and window frames and the wall is treated. This kind of installation method is more common at present.
The above is the introduction of the main materials and installation methods of aluminum alloy doors and windows, hope to help you!
