Description

Technical Field

[0001] The utility model particularly relates to an invisible mortise and tenon floor structure. Background Art

[0002] After a large piece of wood is cut into boards, the wood tendons themselves are not broken. After long-term use, slight deformation of some parts of the wood will cause larger cracks due to the extension and traction of the wood tendons. In order to solve this problem, the authorization announcement number CN203361951U announced a new type of wooden door panel. The new type of wooden door panel includes multiple small boards, and multiple small boards are spliced ​​together to form a door panel. This new type of wooden door panel effectively breaks the wood tendons and cuts off the extension between the tendons, effectively solving the deformation phenomenon of the wood caused by thermal expansion and contraction. However, this pure straight-jointed wooden board is prone to tile deformation and bending after a period of use. Utility Model Content

In the technical solution of the application, it is preferred that the upper solid wood board 1, the lower solid wood board 2 and the core material are of the same species. The same species here refers to boards with the same or similar density and oil content. As Example 1, the thickness of the upper solid wood board 1 is 2-5mm, the thickness of the lower solid wood board 2 is 2-5mm, the thickness of the core material is 8-15mm, and the lengths of the upper solid wood board 1, the lower solid wood board 2 and the core material are all 1200-3000mm. During the assembly process, the horizontal solid wood strips 3 and the vertical solid wood strips 4 of the core material can be assembled first, and then Figure 2 The number of vertical wood strips 4 is set to 3, such as Figure 2 As shown, three vertical wood strips 4 are spaced apart along the length direction, and transverse wood strips 3 are arranged between adjacent vertical wood strips 4. The two ends of the transverse wood strips 3 can be connected to the corresponding vertical wood strips 4 through mortise and tenon joints, thus completing the core material assembly. Then one side of the core material is bonded to the lower solid wood board 2 through an adhesive layer, and then the upper solid wood board 1 is also bonded to the core material through an adhesive layer.
