Multi-layer grooved and tongued floor

The utility model discloses a multi-layer floor with rabbets, which comprises a core plate that is composed of multi-layer splicing plates of solid wood, wherein, a density plate layer, a wood-grain decorative layer, and an abrasion resistant layer of aluminum oxide are arranged on the core plate in sequence. Because the density plate layer is also arranged between the core plate and the wood-grain decorative layer by the multi-layer floor with rabbets of the utility model, and because the density plate layer has the characteristics of high intensity and high density, sticking the wood-grain decorative layer on the multi-layer floor with rabbets becomes possible, and a finished product which is formed finally has the advantage of glabrous and beautiful surface. Thus, compared with traditional solid wood floors, the multi-layer floor with rabbets has the advantages of difficult deformation, favorable abrasion resistance, low cost, no color difference, and favorableness for environmental protection.
