Fire-resistant and heat-insulating window structure

The utility model relates to a fire-resistant and heat-insulating window structure which comprises a base course wall body and an insulating layer glued or anchored to the outer surface of the wall body, wherein, a fire-resistant partition structure is fixed within an area with specified length and width on the base course wall body at the upper part or the upper part and the two sides of an exterior window body, the outer edge of the fire-resistant partition structure is tightly connected with an external insulating layer, the inner edge of the fire-resistant partition structure is abutted or aligned with the edge of the window body, and the fire-resistant partition structure includes an insulating mortar layer containing gelatine powder EPS grains. The fire-resistant and heat-insulating window structure provided by the utility model has the following advantages: the fire-resistant partition structure made of insulating mortar containing gelatine powder EPS grains is used, for easy construction or reconstruction, within specified areas at the upper part and the two sides of the exterior window for heat insulation and fire resistance; and the insulating mortar containing the gelatine powder EPS grains is confined to specified areas for fire resistance and has no influence on the overall effect of the exterior insulation of an EPS board thin-plastering exterior wall, thereby facilitating the popularization and implementation of the utility model.
