FIRE-RESISTANT AND LIGHT-PERMEABLE WALLING STRUCTURE Russian patent published in 2000 - IPC

FIELD: construction engineering. SUBSTANCE: fire-resistant walling structure can be used for fire-resistant glazing of structures. Walling structure has metal framework with one or more cells. Each cell accommodates glass assembly. Glass assembly is made up of two or more multilayer glasses located at distance from each other by means of spacers. multilayer glasses are made of two or more thermally-strengthened glasses. Located between glasses are interlayers of polymeric material. Polymeric material is made in the form of photohardening gluing composition from methacrylic derivative of methyl ether with addition of phosphorus-containing oligoether acrylates and imide derivatives of acrylic and methacrylic acids. Glass assembly is gas-filled. Application of aforesaid embodiment of invention allows for enhancing fire-resistance of structure. EFFECT: higher efficiency. 6 cl, 2 dwg
