The invention relates to a housing construction flooring structure, comprising main beams connected end to end, first adapting components helping connect the main beams, auxiliary beams arranged longitudinally between the main beams, and base plates transversely arranged on the auxiliary beams. The auxiliary beams divide an area enclosed by the main beams into a plurality of carrier recesses; parts of the base plates are recessed downward and are embedded in the carrier recesses, parts of the base plates are rested on the auxiliary beams and the main beams; the two ends of the adjacent base plates are provided with first and second fastening units fastened to each other, respectively; first carrier blocks distributed in top-bottom manner and allowing rebars to penetrate in the arrangementdirection of the auxiliary beams and the length direction of the auxiliary beams are fixed onto the upper surfaces of the base plates; the base plates, the main beams and the auxiliary beams are covered with a reinforced concrete layer. The housing construction flooring structure has the advantages of high structural strength, good deformation resistant strength, and good resistance to quakes andbreaking.
