Description

Technical Field

[0001] The utility model relates to the technical field of wood-based panel production, in particular to a deformation-resistant plywood. Background Art

[0002] For existing plywood products, since the wood units constituting the plywood are large, the characteristics of easy deformation of wood are retained. At the same time, since the veneer used for producing plywood is produced by rotary cutting, stress imbalance exists in the veneer itself. At the same time, due to differences in many factors such as the tree age and wood density of the materials used for the same sheet, after the plywood is produced, huge stresses exist inside, and as the moisture changes during use, the stresses are released, resulting in inevitable stress imbalance and causing the sheet to deform. Summary of the Utility Model

[0003] Based on this, in view of the problem that existing plywood releases stresses due to moisture changes during use, resulting in inevitable stress imbalance and causing the sheet to deform, it is necessary to provide a deformation-resistant plywood.

[0004] A deformation-resistant plywood includes a panel layer and a core board layer connecting the panel layer. The number of the panel layers is two, and the two panel layers are respectively arranged at both ends of the core board layer. The panel layer is a vertical wood board, and the vertical wood board is a vertically sliced veneer of engineered wood. The core board layer is formed by stacking a plurality of inner core boards.

[0005] For the above deformation-resistant plywood, by using vertically sliced veneer of engineered wood as the panel layer, the bending moment of the panel layer is relatively larger than that of the core board layer. And the panel layers are arranged at both ends of the core board layer, so that the bending moment distribution of the whole deformation-resistant plywood is in the shape of "I". In this way, the deformation resistance of the deformation-resistant plywood is effectively improved, and at the same time, the production cost is not increased, and the appearance can be no different from that of traditional ordinary plywood.

[0006] In one embodiment, the inner core boards are divided into transverse core boards and longitudinal core boards, and the transverse core boards and the longitudinal core boards are stacked in an alternating manner.

[0007] In one embodiment, the transverse core board is a horizontally laid rotary cut board.

[0008] In one embodiment, the longitudinal core board is a longitudinally laid rotary cut board.

[0009] In one embodiment, the deformation-resistant plywood further includes a decorative layer, and the decorative layer is arranged at one end of the panel layer away from the core board layer.

[0010] In one embodiment, the thickness of the panel layer is 1.2 mm.

[0011] In one embodiment, the thickness of the inner core board is 15.6 mm. Description of the Drawings

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features.

[0024] Please refer to Figure 1 , an anti-deformation plywood 100 according to an embodiment of the present utility model, comprising a panel layer 10 and a core board layer 20 connecting the panel layer 10. The number of the panel layers 10 is two, and the two panel layers 10 are respectively disposed at both ends of the core board layer 20.

[0025] Please refer to Figure 1 , the panel layer 10 is a vertical wooden board, and the vertical wooden board is a vertically sliced veneer of a vertical technology wood square. The vertically sliced veneer of the vertical technology wood square can be vividly understood as being formed by splicing a plurality of vertically arranged small wooden sticks 11 in a straight line. The thickness of the vertical wooden board is 1.2 mm, thereby effectively improving the compressive and tensile properties of the panel layer 10.

[0026] Please refer to Figure 1, the core board layer 20 is formed by laminating a plurality of inner core boards. The inner core boards are divided into transverse core boards 21 and longitudinal core boards 22, and the transverse core boards 21 and the longitudinal core boards 22 are laminated in an alternating manner. The transverse core board 21 is a horizontally laid rotary cut wood board. The longitudinal core board 22 is a vertically laid rotary cut wood board. The thickness of the inner core board is 15.6 mm. Through such a structural arrangement, the anti-deformation ability of the core board layer 20 can be effectively improved.

[0027] Please refer to Figure 1 , the anti-deformation plywood 100 further includes a decorative layer 30, and the decorative layer 30 is provided at one end of the panel layer 10 away from the core board layer 20.

[0028] The working principle of the anti-deformation plywood 100 in this embodiment: The vertical veneer cutting of the veneer increases the bending resistance of the entire plywood. The panel layers 10 are respectively provided at both ends of the core board layer 20, making the structure of the entire anti-deformation plywood 100 symmetrical. When the anti-deformation plywood 100 is compressed, the upper panel layer 10 resists compression and the lower panel layer 10 resists tension, with strong anti-deformation ability and not easily deformed.

[0029] The beneficial effects of the present utility model are as follows: By using the vertical veneer cutting of the veneer as the panel layer 10, the bending moment of the panel layer 10 is relatively larger than that of the core board layer 20. The panel layers 10 are respectively provided at both ends of the core board layer 20, and the bending moment distribution of the entire anti-deformation plywood 100 is in the shape of "I". In this way, the anti-deformation ability of the anti-deformation plywood 100 is effectively improved, while the production cost is not increased, and the appearance is no different from that of traditional ordinary plywood.

[0030] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0031] The above-described embodiments only represent several implementation manners of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
