Sectional external wall insulation fireproof structure

The invention discloses a sectional external wall insulation fireproof structure. The sectional external wall insulation fireproof structure is characterized in that a bottom bracket on the surface of an external wall is coated with a layer of bonding mortar, a layer of rectangular or square polystyrene molding plates are uniformly distributed on the bonding mortar, a fireproof bar is tightly clamped and fixed in the gap between every two adjacent molding plates, at least four anchor bolts are driven into and fixed with the bottom bracket on the molding plates, the molding plates and the fireproof bars are all coated with layers of fireproof mortar, the fireproof mortar is covered with a layer of gridding cloth, and a layer of finishing mortar is fixed on the gridding cloth. According to the sectional external wall insulation fireproof structure, as the polystyrene molding plates are covered with the layer of fireproof polymer dry-mixed mortar to form facing EPS plates, and then the fireproof bars are adopted
