Description

Technical Field

[0001] This application relates to the technical field of lumber boards, and specifically to a high-toughness laminated veneer lumber board. Background Art

[0002] Laminated veneer lumber is a material formed by laminating thick veneers along the grain direction, hot-pressing and gluing, and then sawing. It is used for structures that bear loads for a long time, such as the beams and columns of large-span building facilities, load-bearing structural components of wooden houses, vehicles, ships, bridges, etc. Such materials have good structural stability and durability.

[0003] A prior patent (publication number: CN201950874U) discloses a laminated composite reinforced board of plastic and poplar veneer chips. It has a seven-layer structure. The first, third, fifth, and seventh layers are plastic thin boards or wood-plastic thin boards with a thickness of 1-3 mm pressed from recycled waste plastics; the second and sixth layers are boards made of poplar veneer chips in a curtain shape with specified gaps, and the boards are longitudinally laid; the fourth layer is a board made of poplar veneer chips in a curtain shape with specified gaps, and its laying direction is the same as, orthogonal to, or in any direction of the first layer. Advantages: A laminated board with reinforcing ribs formed by overlapping plastic sheets and poplar veneer chips in a criss-cross manner. The poplar veneer chips are prefabricated into curtain-shaped sheets, which play a layered sandwich core structure-like layered strengthening role in the board. The gaps between the curtain-shaped veneer sheets enable the plastic sheets between the layers to be mixed and integrated up and down, tightly connecting the sheet-like layered structure of poplar veneer sheets. The product has high strength, good toughness, high impact resistance, low cost, and a wide range of applications.

[0004] However, laminated wood boards are mostly used for load-bearing structural components such as the beams and columns of large-span building facilities, wooden houses, vehicles, ships, bridges, etc., which mostly bear large loads. However, during the use of the above-mentioned boards, the toughness is poor, and after being used for a long time, deformation is likely to occur. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, this application provides a high-toughness laminated veneer lumber board, which has the advantages of high toughness and solves the problems raised in the background art.

[0006] To achieve the above purpose, this application provides the following technical solution: A high-toughness laminated veneer lumber board includes a diamond-shaped framework. Flexible boards are provided above and below the diamond-shaped framework. Fire-retardant boards are provided on the sides of the two flexible boards facing away from each other. Wear-resistant boards are provided on the sides of the two fire-retardant boards facing away from each other. Waterproof layers are provided on the sides of the two wear-resistant boards facing away from each other.

[0007] A plurality of chimeric grooves arranged in a cross pattern are formed on the sides of the two flexible boards facing each other, and the two flexible boards are adapted to the diamond-shaped framework.

[0008] Through the above solution, by setting the flexible board as a white paraffin wood board, the characteristics of its tough texture, high strength, and tight structure can be utilized to effectively improve the overall toughness strength. In cooperation with the embedded PVC diamond-shaped skeleton, it can effectively improve the overall flexibility and weather resistance. Due to the diamond-shaped setting of the diamond-shaped skeleton, it can improve the reset performance of the white paraffin wood board and effectively avoid plastic deformation caused by long-term stress. By setting the waterproof layer and wear-resistant board, the overall wear resistance and waterproofness are effectively improved, making up for the insufficient anti-permeability of the white oak wood board and further improving the overall climate resistance.

[0009] Further, the diamond-shaped skeleton is integrally formed of PVC.

[0010] Through the above solution, by setting the diamond-shaped skeleton to be integrally formed of PVC, it can have good chemical corrosion resistance and weather resistance.

[0011] Further, the two flexible plates are white wax wood boards.

[0012] Through the above solution, by setting the flexible plate as a white wax wood board, due to the tough texture, high strength, and tight structure of the white wax wood, the overall toughness can be improved.

[0013] Further, the two flame retardant boards are both set as oak wood boards, and the flame retardant boards are flame retardant treated.

[0014] Through the above solution, by setting the flame retardant board as an oak wood board and performing flame retardant treatment, the hardness of the overall surface layer can be improved and it can be flame retardant, thus improving safety.

[0015] Further, the two wear-resistant boards are both made of maple wood.

[0016] Through the above solution, by setting the overall surface layer as maple wood, its wear resistance is better and it can resist daily use and mild wear.

[0017] Further, the two waterproof layers are both waterproof oil wax.

[0018] Through the above solution, a waterproof protective film can be formed through the waterproof oil wax, effectively isolating moisture, thereby protecting the internal structure and improving the service life.

[0019] Further, the diamond-shaped skeleton is bonded to the two flexible boards, the two flexible boards are bonded to the flame retardant boards, and the two flame retardant boards are bonded to the wear-resistant boards.

[0020] Through the above solution, through the bonding of the whole, the flatness of the surface can be ensured.

[0021] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0022] This high-toughness laminated veneer lumber board has a flexible board made of paraffin wood board. By utilizing its characteristics of toughness, high strength, and compact structure, it effectively improves the overall toughness strength. In cooperation with the embedded PVC diamond-shaped skeleton, it can effectively improve the overall toughness and weather resistance. Due to the diamond-shaped setting of the diamond-shaped skeleton, it can improve the reset performance of the paraffin wood board, effectively avoiding plastic deformation caused by long-term stress. By setting the waterproof layer and wear-resistant board, it effectively improves the overall wear resistance and waterproofness, compensating for the insufficient anti-permeability of the white oak wood board and further improving the overall climate resistance.
