Code requirements for architectural design
According to the Code for Architectural Design issued on 20 17, every household needs a room with a building height of more than 54m to meet the specific requirements: the external walls and windows can be opened, and the fire resistance time of internal and external firewalls should not be less than 1 hour. The doors of the room are Class B fire doors, and the windows are fire windows with fire integrity not less than 1 hour.
The key to meet the fire integrity standard
How to ensure the fire integrity of aluminum alloy fire windows to reach 1 hour? At present, the manufacturers meeting this requirement in the market mainly use steel or composite grouting or glass materials. However, the steel frame cannot meet the air tightness requirements, and the fire resistance time of ordinary aluminum alloy fire windows is often less than 1 hour.
Patent product aluminum alloy fire-proof window
In order to solve the problem that the fire integrity of aluminum alloy fire-proof window reaches the standard, we have developed a patented product-aluminum alloy fire-proof window, which can reach 1 hour and has passed the fire detection. The window not only meets the national standards and fire detection standards, but also the product has passed the acceptance test successfully.
Professional installation method
As for the installation, we adopt a professional method: first put the cushion block on the lower wall and measure the mark, then put the window frame into the window opening for calibration. Next, we calibrate the levelness of the lower frame and plug the pad, and adjust the seam with the wall and the gap distance between the walls. Finally, fix the upper frame and check the flatness of the window frame with a level.
