[0015] The specific embodiments of the utility model will be further described below. It should be understood that the description of the embodiments of the utility model herein is not used to limit the protection scope of the utility model.

[0016] As shown in Figure 1 The structure schematic view of the spliced floor with compactness provided by the utility model. The spliced floor with compactness comprises a core layer 10 and a decorative layer 20 laid on the upper surface of the core layer 10. It is conceivable that the spliced floor with compactness also comprises some other functional modules, such as a glue module, a shearing module and the like, which are known to those skilled in the art, and will not be described one by one here.

[0017] Please refer to Figures 2 to 4, the core layer 10 is a parallelogram in transverse section, and the included angle between the long side and the short side is 30°-60°, preferably 45°. Thus, when the floor is spliced, two adjacent floors are staggered in the same direction, so that the axial joints form staggered lines, thereby enhancing the ornamental value of the floor. The core layer 10 is provided with a short male buckle 11 and a short female groove 12 on the opposite short sides. The core layer 10 is provided with a long male buckle 13 and a long female groove 14 on the opposite long sides. The short male buckle 11 and the core layer 10 have a short connecting part 15, the long male buckle 13 and the core layer 10 have a long connecting part 16, the thickness of the short male buckle 11 is less than the thickness of the long male buckle 13, and the thickness deviation is 10%-30%, preferably 20%. The thickness of the short connecting part 15 is less than the thickness of the long connecting part 16, and the thickness deviation is 5%-10%, preferably 7.5%. The thickness of the short female groove 12 is the same as the thickness of the long female groove 14, and the width of the short female groove 12 is less than the width of the long female groove 14, and the thickness deviation is 10%-30%, preferably 20%. Thus, the two adjacent sides of the same floor form different heights. When three floors are spliced, the short male buckle 11 on the first floor 30 is clamped in the short female groove 12 on the second floor 40, and the long male buckle 13 on the first floor 30 is clamped in the long female groove 14 on the third floor 50. Thus, when the fourth floor 60 is installed between the second floor 40 and the third floor 50, the fourth floor 60 will tightly pull the second floor 40 and the third floor 50 together due to the different heights of the two adjacent sides of the same floor, thereby improving the splicing strength and connection strength between the second floor 40 and the third floor 50. Correspondingly, when all the floors are laid, any floor will tightly pull the adjacent two sides of the floor together, thereby enhancing the splicing strength and connection strength between the floors and improving the connection stability.

[0018] The long male buckle 13 is provided with a protruding part 17 on the side away from the core layer 10. Correspondingly, the long female groove 14 is recessed towards the core layer 10 to form an inner recess 18, and the protruding part 17 and the inner recess 18 are matched to enhance the connection strength between the two floors. The upper surface of the protruding part 17 is obliquely arranged to facilitate the buckling of the protruding part 17 into the inner recess 18.

[0019] The core layer 10 is a wood material treated by a supercritical drying method, and the specific preparation process is as follows: I. providing a wood composition containing 50% to 70% wood material; II. optionally delignifying the wood composition to remove at least part of the lignin, thereby forming a wood material with delignified structure; III. placing the wood material in supercritical carbon dioxide for heat drying to densify the wood material.

[0020] Supercritical carbon dioxide is a recyclable and non-toxic solvent, which is a solvent between liquid and gas. When the wood material is soaked in supercritical carbon dioxide, by adjusting the pressure and temperature, the supercritical carbon dioxide fluid can penetrate into the micropores of the wood, gradually replacing the water molecules in the wood, thereby rapidly dehydrating the wood. And by precisely controlling the temperature and pressure, the density of supercritical carbon dioxide can be adjusted to increase the density and hardness of the wood, thereby improving the densification of the wood.

[0021] The decorative layer 20 covers the surface of the core layer 10, and the surface of the decorative layer 20 is processed by a floating sculpture process, that is, the soft part of the decorative layer 20 is brushed off by a brush, and the hard part is left, thereby forming a unique texture, thereby improving the appearance of the densified spliced floor.

[0022] Compared with the prior art, the spliced floor with density provided by the present application has different heights of the male buckles on the same floor, so that after the floor is laid, any floor can tightly pull the adjacent two floors together, thereby improving the splicing strength and connection strength between the floors and improving the connection stability. The core layer 10 is treated by a supercritical drying method, so that the supercritical carbon dioxide fluid penetrates into the micropores of the wood, gradually replacing the water molecules in the wood, thereby rapidly dehydrating the wood. And after the core layer is penetrated by supercritical carbon dioxide, the densification and hardness of the core layer can be improved, the structural integrity is maintained, the wood is prevented from cracking due to surface tension, and the collapse is significantly reduced.

[0023] The above merely is the preferred embodiment of the present application, and is not used for limiting the protection scope of the present application, and any modification, equivalent replacement or improvement etc. within the spirit of the present application are all covered in the claim scope of the present application.
