Detailed Description
As shown in fig. 2, the embodiment describes a fire resistant window, which includes a frame structure 2 and glass 3, wherein in the installation process of the fire resistant window, the frame structure 2 is installed in a window opening reserved in a wall body, the outer side wall of the frame structure 2 is attached to the window opening reserved in the wall body, and the glass 3 is clamped inside the inner frame of the frame structure 2.
As shown in fig. 2, the frame structure 2 includes an outer frame structure 21, an inner frame structure 22, a clamping frame 23 and first heat-insulating strips 24, the outer frame structure 21 and the inner frame structure 22 are connected through the first heat-insulating strips 24, the first heat-insulating strips 24 are clamped with the outer frame structure 21 and the inner frame structure 22, the number of the first heat-insulating strips 24 is generally two or more, the clamping frame 23 is clamped at the inner side of the inner frame structure 22, and the glass 3 is clamped between the clamping frame 23 and the outer frame structure 21. The outer frame structure 21 and the inner frame structure 22 are spaced through the first heat insulation strips 24, so that a good heat insulation effect can be provided, the heat transfer speed of indoor and outdoor is reduced, and the heat insulation performance is improved; the design of card frame 23 can promote the convenience of frame structure 2 centre gripping installation glass 3, promotes the installation effectiveness. The inner frame structure 22, the outer frame structure 21 and the clamping frame 23 are generally made of aluminum alloy materials and are convenient to form, and the first heat insulation strips 24 are generally made of nylon composite glass fibers and can reduce the heat conduction speed between the outer frame structure 21 and the inner frame structure 22 to the greatest extent.
After a fire breaks out, the temperature can be continuously raised, and the melting point of the aluminum alloy is low, so that the outer frame structure 21 and the clamping frame 23 are easily melted, the glass 3 is unstable and even falls off, and the problem that the fire cannot be isolated is caused. In this embodiment, as shown in fig. 2, an L-shaped steel fixture 26 is provided in the frame structure 2, the bottom edge of the steel fixture 26 is fixedly connected to the inner frame structure 22, the side edge of the steel fixture 26 is located between the glass 3 and the outer frame structure 21, and the bottom edge of the steel fixture 26 is located above the first heat insulating strip 24. When the conflagration breaks out, frame structure 21, the setting of inner frame structure 22 and first heat insulating strip 24, can reduce heat conduction's speed, generally be the outside of frame structure 21 to the hot side, the temperature is from frame structure 21 progressively to inner frame structure 22 transmit, after frame structure 21 melts because of the high temperature, glass 3 also can carry out the centre gripping through inner frame structure 22 and steel mounting 26, guarantee glass 3's stability, guarantee that the conflagration takes place the back window and can keep longer time stability, provide the valuable time for the rescue.
