Aluminum doors and windows factory for the project construction can be considered a sort of a small cost item, where there is cost, where there is cost control, today the Chinese curtain wall network ALwindoor.com Xiaobian to share and benchmark housing prices in the design, construction and cost Three aspects of the aluminum alloy doors and windows engineering technology and cost control.
1. Aluminum profiles
First is the raw material. Generally used 6063-T5, cross-sectional size of the profile of the allowable deviation is divided into ordinary level, high-precision level, ultra-high precision level, the general implementation of the general level, only the size of the assembly relationship or high-grade doors and windows, High precision level.
Second, the minimum wall thickness of the profile. Aluminum alloy doors and windows of the main section of the wall thickness should be calculated or experimentally determined, in addition to the pressure of the plate, buckle plate and other parts need to be flexible assembly of the outside, the door with the main section of the main part of the substrate (entry "substrate" provided by the industry Encyclopedia ) Minimum cross-section measured wall thickness should be ≥ 2.0mm, the main window with the main part of the main part of the cross-section of the substrate measured wall thickness should be ≥ 1.4mm.
2. Safety regulations
First of all, large mobility of public places, vulnerable to the collision of personnel and objects of aluminum alloy doors and windows should be used safety glass;
Secondly, the following parts of the building of aluminum alloy doors and windows should use safety glass:
A.7 or 7 above the building outside the window;B. The area of the window is greater than 1.5 square meters;C. Floor-to-ceiling windows with a glass bottom edge less than 500 from the final finish;D. Tilt-mounted aluminum alloy windows.
Third, aluminum alloy sliding doors, sliding window fan, there should be removed from the outdoor side of the device. Sliding window for the external walls, should be set to prevent the sash to the outdoor shedding device.
3. Lightning protection design
Aluminum alloy doors and windows company lightning protection design should be consistent with the current national standard "Building lightning protection design specifications" GB50057 the relevant provisions.
4. Design the service life
According to "Residential Performance Evaluation Technical Standard" GB / T50236-2005 Article 8, doors and windows of the design life is not less than 20 years, 25 years, 30 years, three grades.
