(57) The invention relates to the technical field of civil engineering, in particular to a novel prefabricated concrete frame structure system based on UHPC and a construction method thereof. The novel prefabricated concrete frame structure system comprises a foundation, prefabricated columns are symmetrically and fixedly arranged at the top end of the foundation, and the interiors of the prefabricated columns are hollow; cantilever beams are fixedly arranged in the middles of the opposite faces of the prefabricated columns, a prefabricated beam is arranged between the two cantilever beams, and the cantilever beams are connected with the prefabricated beam through UHPC pouring areas. The top ends of the prefabricated columns are jointly provided with a connecting beam, a first clamping block is fixedly arranged on one side of the bottom end of the connecting beam, a second clamping block is fixedly arranged on the other side of the bottom end of the connecting beam, and the first clamping block and the second clamping block are both located in the prefabricated columns. The cantilever beam and the precast beam are connected through the UHPC pouring area, the strength of the connecting face can be enhanced, and operation is easier and more convenient due to the light structure; the cantilever beam is arranged on the prefabricated column, so that the damage degree of the prefabricated column when the prefabricated beam is damaged and fractured can be reduced.
