Two-layer floor of base material structure

The invention provides a two-layer floor of a base material structure. The two-layer floor is characterized by comprising a core board, edgings, a veneer and a reinforcing strip, wherein the core board, the edgings and the reinforcing strip are mutually matched through S-shaped cambered surfaces or arc surfaces so as to constitute a floor base material. A processing technology of the two-layer floor includes the first step of connection of the core board, the second step of component shape milling, the third step of assembly of the base material, the fourth step of determining the thickness of the base material, the fifth step of covering the base material with the veneer, and the sixth step of forming the floor. The two-layer floor has the advantages that mutual matching through the S-shaped cambered surfaces or arc surfaces is adopted, so that the combining mode of the core board and the edgings is optimized, the contact area is increased, the hidden danger that combining force is not enough since the wood
