The invention provides a fireproof heat insulation plate with an air storage bag. The fireproof heat insulation plate includes a plate body, and the plate body is of a cube structure. The upper surface of the plate body is provided with a waterproof abrasion-resistant layer, the middle portion of the plate body is provided with a fireproof layer, and the lower portion of the plate body is providedwith a heat insulation layer. The waterproof abrasion-resistant layer, the fireproof layer and the heat insulation layer adhere through a flame-retardant adhesive. A plurality of air storage films are arranged in the fireproof layer. Inert gas is in the air storage films. The air storage films are high temperature-resistant films. The inert gas is nitrogen. The fireproof heat insulation plate hasthe advantages that the fireproof heat insulation plate is simple in structure and convenient to use, and the air storage films containing the inert gas are added in the fireproof layer, so that notonly is a fireproof effect improved, but also a heat insulation effect is also added.
