The invention discloses a wall surface mounting structure based on fabricated keels. The wall surface mounting structure comprises a base, wing plates, positioning plates, a ground keel, connecting seats, connectors and vertical keels. Through holes are formed in one sides of the vertical keels, center-penetrating keels are movably connected into the through holes, inserting holes are formed in the front surfaces of the center-penetrating keels, fixing rods are movably connected into the inserting holes, connecting rods are fixedly connected to one ends of the fixing rods, lantern rings are fixedly connected to one ends of the connecting rods, inserting plates are movably connected into the lantern rings, and wall surfaces are fixedly connected to one sides of the inserting plates. The wall surface mounting structure based on the fabricated type keels has the main advantages that the time for waiting for concrete solidification in a traditional construction mode is avoided, concrete stirring operation needing to be conducted on a construction site is reduced, flying dust on the construction site is reduced, the construction environment of workers is improved, and the construction period of the building wall surface is shortened.
