[0035] Specifically, by embedding the limiting slot 106 of the upper wood-plastic composite flooring 1 above the lower wood-plastic composite flooring 2, and fixing the upper wood-plastic composite flooring 1 through the positioning slot 207, the upper wood-plastic composite flooring 1 and the lower wood-plastic composite flooring 2 are connected. After connection, the assembly slot 3 between the upper wood-plastic composite flooring 1 and the lower wood-plastic composite flooring 2 is used to fix adjacent upper wood-plastic composite flooring 1 and lower wood-plastic composite flooring 2, which is convenient and quick, and the positioning structure is stable. Through the inclined reinforcing plate 103 and the segmented reinforcing plate 203, the positions of the first sound insulation plate 102 and the second sound insulation plate 202 are kept stable for long-term work, improving service life and making it highly practical.
