Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a schematic diagram of the results of the present invention;
fig. 2 is a cross-sectional view at a-a in fig. 1.
Detailed Description
Referring to fig. 1 and 2, the fireproof safety observation window comprises a window frame 1 and fireproof glass 2 arranged on the window frame, wherein the fireproof glass 2 is formed by clamping a plurality of silicon dioxide crystal interlayers 21 by flat glass 22, has the advantages of high temperature resistance, high hardness, large monomer area and the like, does not turn yellow or turn white for more than 10 years, has stable and reliable quality, is not afraid of sunlight, can be used in outdoor places, and has wider application range; the window frame 1 comprises a fireproof frame 3 arranged around the periphery of the fireproof glass 2, and an aluminum silicate fiber strip 4 embedded at the periphery of the fireproof glass 2 is arranged between the fireproof frame 3 and the fireproof glass 2; the fire-resistant glass 2 is provided with a fire-resistant decorative cover 5 for shielding the fire-resistant frame 3 and the aluminum silicate fiber strip 4 on the fire-facing and back fire surfaces, and a glass magnesium plate 6 with a flame-retardant effect is laid between the inner side wall of the fire-resistant decorative cover 5 and the fire-resistant frame 3 and between the inner side wall of the fire-resistant decorative cover and the aluminum silicate fiber strip 4, so that the fire-resistant glass has a compact and complete structure and a good flame-retardant effect, and meets the heat resistance requirement of the architectural design.
Specifically, the fire resistant glass 2 includes a three-layer silica crystal interlayer 21 composed of four layers of plate glass 22. Compared with the traditional composite fireproof glass, the fireproof glass 2 adopting the silicon dioxide crystal interlayer has higher heat-resistant temperature and hardness, and simultaneously can not cause the problem of whitening and yellowing caused by the internal chemical change due to the change of the environment or time.
