The utility model discloses a novel block type outer formwork cast-in-place concrete composite heat preservation system which comprises a base layer wall body and a heat preservation plate layer, an inner side anti-crack plastering mortar layer is arranged between the heat preservation plate layer and the base layer wall body, and a heat preservation mortar leveling layer, an outer side anti-crack plastering mortar layer and a facing layer are sequentially arranged on the outer side of the heat preservation plate layer. Paired partition grooves are oppositely formed in the two sides of the heat preservation plate layer, and the depth of the partition groove in at least one side between the paired partition grooves is smaller than one half of the thickness of the heat preservation plate layer. The separation grooves are filled with A-level fireproof materials. The utility model has the technical effect that by adopting the structure, the problem that the fireproof grade of the thermal insulation external templ
