Technical Field

[0001] This invention relates to Technical Field of Improved Fire-Resistant Support Structure for Aluminum Alloy Windows In particular, a fire-resistant aluminum alloy window reinforcement structure. Background Technology

[0002] Aluminum alloy windows are currently a popular building material, characterized by their lightweight and aesthetic appeal. Their main structure consists of a window frame for installation and support, and a window sash with transparent glass. The structure of the window frame is as follows: Figure 2 As shown: The system includes an inner frame 28 and an outer frame 23, which are connected to each other by connectors 26. After the support member 13 is inserted, the glass 9 is installed, and finally, the retaining strip 1 is fastened. An outer sealing strip 12 is installed between the outer surface of the glass and the vertically upward-extending edge 18 of the outer frame. An inner sealing strip 8 is installed between the inner surface of the glass and the retaining strip. A buckle 15 is located on the inner side of the upper end face 20 of the outer frame, and a buckle 7 is located on the outer side of the upper end face of the outer frame. In actual use, during a fire, due to the low melting point of aluminum alloy, it will soften and deform after being exposed to heat for a period of time.
