20 17 The newly issued Code for Architectural Design (gb500 16-20 17) clearly requires additional shelter for houses over 54m: for houses with a building height of over 54m, every household should have a room that meets the following requirements: external walls should be set and windows should be set; The internal and external firewalls shall not be less than 1.00 hours, the room doors shall be Class B fire doors, and the windows shall be fire windows with fire integrity not less than 1.00 hours. ..
At present, the manufacturers of aluminum alloy fire windows that meet the fire resistance limit of 1 hour are basically steel or composite grouting or glass. Because the steel frame is not formed by extrusion, it can't meet the requirements of air tightness. At present, the fire protection time of ordinary aluminum alloy fire windows is less than 1 hour. Therefore, in this case, our company's patented products were developed in aluminum alloy fire windows, mainly combining the original materials with the fire characteristics of steel fire windows. Through special websites, the fire integrity of aluminum alloy fire windows 1 hour can be eliminated, and it has passed the fire detection. This kind of aluminum alloy fire window meets the national standards and fire detection standards, and the product passed the acceptance test smoothly.
Installation of aluminum alloy fire-proof window: put the pad on the lower wall and pay attention to the measurement marks. Place the window frame in the window and move the calibrated position in the window to both sides; Correcting the levelness of the lower frame, inserting the lower frame, and adjusting the seam with the wall and the average gap distance of the wall; Pay attention to the gap in the upper frame, and pin the frame at the upper end of the mullion. Check and adjust the contact between the mullion and the edge, use a level, and the outline of the window frame should be straight. Don't deform the profile when using the pin.
