3 arranged transversely when the wood plates are assembled into a floor the transverse structure may improve buckling deformation or anti twist deformation performances when in use particularly in dry humid or terrestrial heat supply environments in addition during material selection the plurality of strip shaped solid wood cores 3 and the frames 2 are both made of fast growing timbers so the inventive concept has environmental economical stable and multiple choice material resources and is more aligned with the ecological protection requirements of the society in addition a two layer structure is employed in this embodiment compared with other three layer structures the raw materials are saved and the bending deformation of the surface layer and bottom layer of a three layer structure due to different materials and thicknesses is avoided in addition a two layer structure is employed in this embodiment so the plurality of strip shaped solid wood cores 3 and the frames 2 are completely exposed outside thereby avoiding adulteration and falsification and making users more assured in other embodiments a method of manufacturing the floor product described above is provided the method includes assembling the floor support main body layer and affixing an upper decorative surface layer to the top side of the main body layer assembling the main body layer includes positioning two solid wood frame components in parallel to one another with a space between them inserting two or more strip shaped.
