The utility model discloses a suspended spliced ceiling structure using plastic floors. The suspended spliced ceiling structure comprises the plastic floors (3), pins (1) and fasteners (2) are arranged at the edge of each plastic floor (3), and the plastic floors (3) are integrally connected with one another through the pins (1) and the fasteners (2) in a fastening mode to form a stable whole. The plastic floors (3) are of semi-hollowed-out structures. The suspended spliced ceiling structure is rapid to mount, flatness can be guaranteed, deformation and cambering can be avoided, and bearing capacity of top-surface suspenders can be reduced.
