Description of the invention: [Technical field to which the invention pertains] The present invention relates to a solid wood floor, in particular to avoiding deformation and lifting, and to restore the flatness of the arch after the damp, prolonging the service life of the floor, and further adding logs. Rate and reduce the amount of wood felling wood flooring. [Prior Art] Since the solid wood floor has an aesthetically pleasing surface and includes various advantages such as adjusting the indoor temperature and avoiding insects, it has been widely used in indoor laying and decorating. Please refer to the fourth figure. The unit body of the solid wood floor (2 〇) is generally cut from the logs, and the entire part of the growth texture (annual ring) is cut to form a plate or strip of a predetermined size with one side protruding. There is a male donkey (2 i ), and the other side is formed with a female donkey (22); when laying, the male (2 1) and the female (22) of the plural single body (20) are engaged with each other. Gradually piece together solid wood flooring that is joined to a certain area. In terms of the characteristics of wood, 'they will have different growth textures on the wood. When the wood is wet, the water gradient of the wood corresponds to the direction of its growth texture' and the cells of the wood will be The absorption of different amounts of water results in varying degrees of enlargement, resulting in the expansion of the size of the wood. Generally, the more the outer side of the wood accumulates, the more the expansion of the internal continuity is, and the greater the amount of deformation. Therefore, when the local surface is wet due to weather or other factors, the unit body (2〇) of the prior art solid wood floor tends to gradually absorb water and generate expansion on both sides depending on the growth texture; The relative external 胄' of the body (2 ◦) 1345020 will cause the adjacent unit body (2 〇) to withstand a certain degree of swell stress', which in turn causes the unit cells (20) to be warped and deformed on both sides. It will cause damage to the furniture doors and windows, and will greatly reduce the overall beauty of the solid wood flooring. The water in the unit body (2 〇) of the existing solid wood floor can be gradually evaporated by the heat collection. The wood itself has irreversibility, that is, the external factor changes the original moisture content of the wood. The increase or decrease causes physical changes (such as anti-warping, deformation), and this phenomenon does not return to the original moisture content before undeformed', and with the restoration of the original shape and flatness 'is' Each unit body (20) will not return to its original state due to evaporation of water, but will continue to maintain its type of lifting on both sides, which makes the prior art solid wood floor use certain troubles. In addition to the aforementioned problems, 'in addition to the above, the single 7C body (2 〇) of the prior art solid wood floor is made to be cut from the logs, and the texture is intact, and the texture is less complete. Or the appearance of the grain can not be used, can only be used to discard or burn it. This leads to a low rate of wood harvesting, which in turn increases the amount of forest felling and has a certain degree of impact on the environment and ecology. SUMMARY OF THE INVENTION The object of the present invention is to provide a solid wood floor, which can effectively solve the problem of deformation and lifting on both sides of a single body 70, further increase the rate of wood harvesting and reduce the amount of tree felling. The solid wood flooring of the present invention includes a plurality of unit bodies having a male cymbal on one side and a female raft on the other side; 6 1345020 The mother and the female are engaged with each other and joined together to form a solid wood floor of a certain area. The main unit body comprises a plurality of base materials and at least one surface material, wherein the base materials are respectively cut from the logs. a small volume body, which is arranged along a plane; and the surface is adjacently arranged, and the growth texture on each substrate is oriented in the same direction; the surface is selected from the logs, and the parts with the complete growth texture are selected for cutting. Cutting, forming a plate body having an area larger than a plurality of substrates, which is laid on the top surface of the substrate,

When the ground is wet due to the sky a or other due to t, the unit body of the solid wood floor of the present invention may be completely inconsistent due to the direction of expansion, thereby reducing the degree of expansion of the sides of each unit body, further avoiding adjacent units. The body is subjected to the swelling stress, which causes the two sides to be warped and deformed, and ensures the overall appearance of the solid wood floor and the durability. In addition, when the unit body of the solid wood floor of the present invention is produced, only the surface of the wood is selected to be cut in the intact texture of the log; the substrate may be incomplete in the texture of the log or the appearance is not The part of the pleasing part is cut and formed, which effectively improves the drawing rate of the logs, thereby reducing the amount of forest felling and achieving the purpose of environmental protection. [Embodiment] Referring to the first figure, the solid wood floor of the present invention is composed of a plurality of unit bodies (10). Each unit body (1 〇) includes a plurality of base materials (work 1) and a watch material ( 12), wherein: the substrate (1 1 ) is respectively divided by a small volume 7 1345020 cut from the log, and if the solid body of the solid wood floor of the invention (1G) 0 is wet, the swelling pressure is usually Focusing on the center, the degree is roughly twisted upwards, such as spit. Therefore, the central door is curved like this. 'The unit after the damp is = inward, reducing the damaged area, and the unit of the piece can be borrowed. From the row:: gradually reduce the water content before the damp and restore the flatness and change the irreversibility of the wood. In addition, in the unit body of the solid wood floor of the present invention, only the sub-section u' is made in the order of the eight-piece material (1 2), and the part in the log is selected for cutting'. The substrate (11) can be = The whole -3⁄4 ^ ^ fj is cut by the texture of the log which is less than the texture of the wood. This effectively improves the original 2 yield rate and thus reduces the amount of forest felling and achieves environmental protection.
