The technical scheme of the invention can achieve the following effects:

(1) compared with the prior art, the artificial structure wood floor provided by the invention has the advantages of high structural strength, small usage amount of adhesive, environmental friendliness, simple manufacturing process, capability of being mechanically processed and capability of saving wood resources, and warping and deformation are not easy to occur.

(2) Some artificial floors among the prior art often have empty groove structure (vertical pressure-bearing body) that link up from top to bottom for some occasion, if need pass through the fastener, like bolt, nail, pin etc. fasten corresponding part, because the plank size is cut according to the on-the-spot condition, when the position of fastening is the position of vertical pressure-bearing just in time, because vertical pressure-bearing body inside is a plurality of empty groove structures, when the fastener inserts vertical pressure-bearing body, its axial is very little with the area of contact of vertical pressure-bearing body, can lead to fastening force less, can't fixed object, damage the structure of vertical pressure-bearing body even in serious time. The core plate structure comprises the inclined pulling structure, so that no matter where the core plate is selected at the fastening position, the fastening piece can be in good contact with the inclined pulling structure in the axial direction when inserted into the plate, the fastening force is increased, and a good fastening effect can be achieved.

(3) The existence of the reinforcing ribs is beneficial to improving the strength of the core plate, has the capability of resisting warping, and reduces the deformation rate of the core plate generated when the temperature and the humidity change. The reinforcing ribs can increase the gluing area of the core strip units and the balance layer, so that the finished board is bonded more firmly and is not easy to degum.

(4) The fiber texture directions of adjacent solid wood veneers in the balance layer are mutually vertical, and the structure can enable the floor to conduct and draw layer by layer through the inside when the floor is stressed in all directions, gradually share the stress outside according to the self pressure-bearing characteristic of the inside, and finally prevent the floor from deforming to the maximum extent.

(5) When the core plate has no breathing channel, the transverse pressure-bearing bodies and the battens arranged at intervals of the inclined pulling structure form a closed space, and water vapor formed in the floor processing and using process is easy to stay in the space, which may cause local bending deformation of the floor. The structure of the breathing channel can be communicated with the closed spaces on the premise of not obviously reducing the strength of the floor, so that water vapor is uniformly dispersed in the closed spaces, and local uneven stress or damp deformation is prevented. And the breathing channel extends to the edge of the core plate, so that the internal space is communicated with the external space, internal water vapor can be discharged, the conditions of humidity, temperature, pressure and the like of the internal air and the external air are equal, the internal stress and the external stress of the floor are balanced, and the floor is not easy to warp.

(6) Two adjacent breathing passages are arranged on the upper surface and the lower surface of the core strip unit, so that the breathing passages are distributed uniformly, the whole structure has good symmetry, and the pressure resistance of the structure is more uniform. If the breathing passages are all opened on the same surface of the core strip unit, the pressure resistance of the surface of the core plate is obviously lower than that of the back surface, and the possibility of bending of the core plate is increased.

(7) When the core strip units in the core plate are in a symmetrical structure, the structure of the invention presents a mirror symmetry structure and has a frame shear structure, thereby effectively decomposing the external force applied to the artificial board and increasing the strength of the core plate.

(8) The manufacturing method of the artificial floor provided by the invention can be used for manufacturing large-block boards with higher strength, better uniformity, less adhesive and lighter weight by fully utilizing wood resources, has a simple manufacturing process and is suitable for large-scale production.
