The invention discloses a modular unit combined prefabricated wallboard comprising an outer surface, a base body and an inner surface. The base body is arranged between the outer surface and the innersurface; reinforcing bars are arranged between outer surface and the inner surface; through holes in the vertical direction are formed in the base body; connecting steel bars are arranged on the twosides of the through hole; a groove is formed in one ends of the connecting steel bars; connecting holes matched with the connecting steel bars are formed in the lower portion of the base body; a heat-preservation core material layer is arranged in the middle of the base body; a cement layer is arranged on the outer side of the heat-preservation core material layer; the connecting steel bars are on the cement layer; fiberglass gridding cloths are arranged between the cement layer and the outer surface; symmetrical convex blocks are arranged on the two sides of the base body; and markers in thevertical direction are arranged on the inner surface and correspond to the through holes in position. The design is novel, the structure is simple, mounting is rapid, heat preservation and fire prevention are achieved, an electric plate is mounted in a normalized mode, and safety and convenience are achieved.
