1. Opening method
2. Most local standards stipulate that external casement windows should not be used in super high-rise buildings to prevent the sash from opening. Fall. For example, Jiangsu Province stipulates that external casement windows shall not be used above the 7th floor, and Shandong Province and Tianjin City also clearly stipulate that high-rise or super high-rise buildings shall not use external casement windows.
3. Sash size
4. When using external casement windows, the size of the sash should be consistent with the sliding brace match the load-bearing capacity. For example, Fujian Province stipulates that the maximum width of window sash should not be greater than 650mm, the height should not be greater than 1500mm, and the opening angle of the window sash should not be greater than 80°.
5. Energy-saving design
6. The energy-saving design of super high-rise buildings is very important. For example, Shenzhen stipulates that transparent curtain walls need to have 10% of the opening area, and windows must be opened when they are above 100m. In Beijing, it is not mandatory to open windows above 100m, but areas without windows need to be ventilated through mechanical ventilation or natural ventilation using ventilators.

Construction technology

1. Installation accuracy
2. The installation accuracy of doors and windows is extremely demanding, and the sealing and stability of doors and windows need to be ensured. Professional measuring tools and installation equipment should be used during the installation process to ensure that the verticality, horizontality and diagonal errors of doors and windows are within the allowable range.
3. Quality control
4. Strict quality control should be carried out during the construction process, including material inspection , intermediate acceptance and final acceptance during the installation process. Each link should have detailed quality records to ensure that the construction quality meets the design requirements and specifications.

Maintenance and maintenance

1. Regular inspection
2. Doors and windows should be inspected and maintained regularly, especially sealing strips, hardware and other vulnerable parts. Regular inspections can be timelyFind and fix problems to extend the life of doors and windows.
3. Cleaning and maintenance
4. Cleaning and maintenance of doors and windows are also very important and should be done with appropriate Cleaners and tools to avoid damage to the door and window surfaces. Regular cleaning maintains the appearance and performance of your windows and doors.

Through the above technical requirements and design specifications, the stability and safety of super high-rise door and window projects can be ensured, and a comfortable and safe environment can be provided for building users. .
