Concrete frame structure with protective layer and construction method thereof

The invention relates to a concrete frame structure with a protective layer and a construction method of the concrete frame structure, belongs to the technical field of structural engineering, and solves the problems that cracks are easily generated at the joint of a beam plate of a large-span concrete frame structure and a stand column, and the crack resistance and durability of the concrete frame structure cannot meet the use requirements. The concrete frame structure with the protective layer comprises a reinforced concrete part and a protective layer assembly. The protective layer assembly is adhered to the reinforced concrete part; the reinforced concrete part comprises a stand column assembly and a beam plate assembly. Concrete frame settlement parts are arranged on the outer surfaces of the stand column assembly and the beam plate assembly; the protective layer assembly comprises a high-ductility material, and the concrete frame settlement part is filled with the high-ductility material.
