Description

Technical Field

[0001] This utility model relates to the field of container technology, and more specifically to a bamboo engineered wood flooring and a container. Background Technology

[0002] Existing methods for joining bamboo engineered wood flooring have numerous problems, severely restricting its performance improvement and wider application. Currently, bamboo engineered wood flooring is mainly joined using methods such as concealed tongue and groove joints, and butt joints.

[0003] In terms of joint strength, traditional splicing methods such as concealed teeth, tenons, and butt joints often fail to produce ideal joint strength. In practical use, specialized equipment like container trucks endure significant loads and frequent vibrations, requiring floor joints to possess sufficiently high strength to ensure structural stability. However, existing splicing methods struggle to meet this requirement, leading to joint damage that negatively impacts the overall lifespan and safety of the floor.

[0004] Therefore, there is a need to provide a bamboo engineered wood flooring and container to at least partially solve the above problems. Utility Model Content

[0007] According to the first aspect of this utility model, the bamboo engineered wood flooring, during splicing, when the tenon is inserted into the mortise, the thicker part of the tenon end can better fit into the mortise, thereby effectively preventing the bamboo unit strips from sliding or separating along the length direction after splicing, greatly enhancing the overall stability of the flooring splice. Through mortise and tenon connections, continuous production is allowed during the flooring manufacturing process, ensuring the joint strength of the bamboo unit strips; during the use of the flooring, bamboo unit strips spliced ​​along the length direction can continue to be connected along the thickness or width direction, making the entire floor more solid and reliable, reducing problems such as abnormal noise and widening gaps caused by loose splicing.

[0008] Optionally, the thickness of the end of the tenon is 1 / 3 to 1 / 2 of the thickness of the floor; and / or The thickness of the tenon neck is 1 / 4 to 1 / 3 of the thickness of the floor.

[0027] Reference Figures 1 to 4 This utility model provides a bamboo engineered wood flooring, comprising bamboo strips 10, multiple bamboo strips 10 stacked along their thickness direction DT2 to form bamboo unit strips 20, at least one end of each bamboo strip 10 along its length direction DL2 having a tenon 21 or a mortise 22, multiple bamboo unit strips 20 spliced ​​along their length direction DL2, adjacent bamboo unit strips 20 being mortised and tenoned together by the tenon 21 and the mortise 22. Along the thickness direction DT1 of the flooring, the thickness T1 of the end 23 of the tenon 21 is greater than the thickness T2 of the tenon neck 24. During splicing, when the tenon 21 is inserted into the mortise 22, the thicker part of the end 23 of the tenon 21 can better fit into the mortise 22, thereby effectively preventing the bamboo unit strips 20 from sliding or detaching along the length direction DL1 after splicing, greatly enhancing the overall stability of the flooring splicing. The mortise and tenon joint allows for continuous production during the flooring manufacturing process, ensuring the extension strength of the bamboo unit strips 20. During the use of the flooring, the bamboo unit strips 20 spliced ​​along the length direction DL2 can continue to be connected along the thickness direction DT2 or the width direction DW2, making the entire flooring more solid and reliable, and reducing problems such as abnormal noise and widening gaps caused by loose splicing.

[0028] In this design, the flooring has a length direction DL1, a thickness direction DT1, and a width direction DW1. The bamboo strips 10 have a length direction DL2, a thickness direction DT2, and a width direction DW2. The bamboo unit strips 20 formed by stacking the bamboo strips 10 have the same length direction DL2, thickness direction DT2, and width direction DW2 as the bamboo strips 10.

[0029] Example 1 Reference Figures 5 to 8 The upper surface 127 and the lower surface 128 of the tenon 121 are both inclined surfaces in the thickness direction DT1. The shape of the mortise 122 is adapted to the shape of the tenon 121.

[0030] Example 2 Reference Figures 9 to 12 The upper surface 227 and lower surface 228 of the tenon 21 are inclined planes oriented in the thickness direction DT1, and the upper surface 227 of the tenon 221 is a straight plane perpendicular to the thickness direction DT1. The shape of the mortise 222 is adapted to the shape of the tenon 221.

[0031] In this design, the mortise and tenon joint allows for unlimited splicing of bamboo strips 10, thus ensuring the stability of the floor's length dimension. The wedge structure not only converts the tensile force in the length direction DL1 into compressive force in the thickness direction DT1, but also increases the friction and interlocking force between the tenon 21 and the mortise 22 in the direction perpendicular to the floor plane (thickness direction DT1); thereby further enhancing the stability of the floor splicing and reliably fixing adjacent bamboo unit strips 20 in multiple directions.

[0032] Optionally, the thickness of the end 23 of the tenon 21 is 1 / 3 to 1 / 2 of the thickness T1 of the flooring. The thickness T1 can be, but is not limited to, 1 / 3, 5 / 12, 2 / 5, 3 / 8, or 1 / 2. This range ensures that the end 23 of the tenon 21 has sufficient thickness to better fit into the mortise 22 after insertion, forming an effective "wedge" fixing effect. This effectively prevents the bamboo unit strips 20 from sliding or detaching along the length direction DL1 after splicing, enhancing the overall stability of the flooring splicing. It also avoids problems such as material waste and splicing difficulties caused by an excessively thick end 23 of the tenon 21. Correspondingly, the mortise 22, in the portion that mates with the end 23 of the tenon 21, is designed to tightly accommodate the end 23 of the tenon 21. The width of the groove bottom 25 of the tenon 22 matches the thickness of the end 23 of the tenon 21, with the error controlled within a very small range (e.g., ±1mm, which can be adjusted according to the actual production process and precision requirements). This ensures that when the tenon 21 is inserted into the tenon 22, the thicker part of the end 23 of the tenon 21 can fit perfectly into the tenon 22, forming a stable and effective "wedge" fixing effect. This effectively prevents the bamboo unit strips 20 from sliding or detaching along the length direction DL1 after splicing, greatly enhancing the overall stability of the floor splicing.

[0033] Optionally, the thickness of the tenon 24 of the tenon 21 is 1 / 4 to 1 / 3 of the thickness T2 of the flooring. The thickness T2 can be, but is not limited to, 1 / 4, 4 / 15, 7 / 24, 5 / 18, or 1 / 3. This range ensures that the tenon 24 has sufficient strength to withstand tensile forces during splicing, guaranteeing the extension strength of the bamboo unit strips 20, while preventing excessive thickness of the tenon 24 from affecting the "wedge" fixing effect. Simultaneously, it ensures the connection strength between the tenon 21 and the mortise 22, guaranteeing the stability of the mortise and tenon connection when subjected to a force along the thickness direction DT1 (i.e., the horizontal plane perpendicular to the flooring). The dimensions of the mortise 22 that mates with the tenon 24 are designed to closely match the thickness of the tenon 24. The width of the groove 26 of the tenon 22 matches the thickness of the tenon 24, with the error controlled within a very small range (such as ±1mm). This ensures that the tenon 24 has sufficient strength to withstand the tensile force during splicing, ensuring the formation of the "wedge" fixing effect, and also ensures the splicing strength of the bamboo unit strip 20.

[0034] Optionally, the angle θ between the bevel of the tenon 21 and the thickness direction DT1 is 30°~75°. The angle θ can be, but is not limited to, 30°, 45°, 50°, 60°, and 75°. By limiting the angle to this range, when the angle is within this range, the tensile force in the length direction DL1 can be effectively converted into the compressive force in the thickness direction DT1. Simultaneously, in the direction perpendicular to the floor plane (thickness direction DT1), the friction and interlocking force between the tenon 21 and the mortise 22 can be effectively increased, further enhancing the stability of the floor splicing. If the angle is too small, the distance between the tenon 21 and the tenon shoulder will be too small, which may make it difficult for the tenon 21 to insert into the mortise 22, affecting the splicing operation. If the angle is too large, the force conversion and the effect of increasing friction and interlocking force may not be effectively achieved. The mortise 22 corresponds to the inner wall that mates with the bevel of the tenon 21, and its inclination angle is consistent with the angle of the bevel of the tenon 21. The angle error is controlled within a very small range (e.g., ±5°, which can be adjusted according to the actual production process and precision requirements). Through this precise angle adaptation, when the included angle is within this range, the tensile force in the length direction DL1 can be effectively converted into the compressive force in the thickness direction DT1. At the same time, in the direction perpendicular to the floor plane (thickness direction DT1), the friction and interlocking force between the tenon 21 and the mortise 22 can be effectively increased, further enhancing the stability of the floor splicing. If the angle adaptation is inaccurate, it may lead to the inability to effectively achieve the effect of force conversion and increase friction and interlocking force, or it may make it difficult for the tenon 21 to insert into the mortise 22, affecting the splicing operation.

[0035] Optionally, the thickness T0 of the bamboo strip 10 is 4mm to 8mm. Thickness T0 can be, but is not limited to, 4mm, 5mm, 6mm, 7mm, and 8mm. Optionally, the width W0 of the bamboo strip 10 is 12mm to 22mm. Width W0 can be, but is not limited to, 12mm, 14mm, 16mm, 18mm, 20mm, and 22mm. By limiting the aforementioned ranges, it is ensured that the bamboo unit strip 20 has sufficient thickness / width to guarantee its structural strength and meet the load-bearing requirements during flooring use; while avoiding problems such as increased material costs, increased processing difficulty, and excessively thick overall flooring after splicing due to excessively thick / wide bamboo unit strips 20.

[0036] Optionally, each bamboo unit strip 20 contains 3 to 5 bamboo strips 10. Controlling the number of bamboo strips 10 in each bamboo unit strip 20 to 3, 4, or 5 helps to precisely control the dimensional accuracy of the bamboo unit strip 20. During the production process, the dimensions of each bamboo strip 10 undergo rigorous testing and screening to ensure that its width, thickness, and length meet standard requirements. This ensures the flatness and tightness of the flooring joints, reduces gaps and misalignments, and improves the overall aesthetics and user comfort of the flooring.

[0037] Alternatively, the tenon 21 and the mortise 22 may be either an interference fit or a clearance fit.

[0038] In this context, an interference fit refers to a tenon 21 whose actual size is slightly larger than the mortise 22. During assembly, external force (such as pressure applied by a press) is required to force the tenon 21 into the mortise 22. After assembly, a significant compressive stress is generated between the tenon 21 and the mortise 22, ensuring a tight bond between them. For example, when the thickness of the end 23 of the tenon 21 is 0.1mm to 0.5mm greater than the width of the corresponding part of the mortise 22, the tenon 21 can be firmly embedded into the mortise 22 by applying appropriate pressure. The compressive stress generated by the interference fit provides greater friction, effectively preventing the tenon 21 from coming out of the mortise 22, greatly enhancing the connection strength between the bamboo unit strips 20. This makes the joints less prone to loosening or separation when the floor is subjected to external forces (such as foot traffic or furniture placement), improving the overall stability of the floor. Simultaneously, the interference fit connection structure provides a sealing effect.

[0039] A clearance fit means that the actual size of the tenon 21 is smaller than the actual size of the mortise 22. During splicing, the tenon 21 can be easily inserted into the mortise 22, with a certain gap between them. The gap size is usually controlled within a certain range, such as 0.01mm to 0.2mm, to ensure the accuracy and stability of the splicing. Before splicing, adhesive can be applied to the tenon 21 and / or the mortise 22. The clearance fit makes the splicing operation of the bamboo unit strips 20 simpler and faster, without the need for complex tools and large external forces, thus improving production efficiency. At the same time, since bamboo has a certain degree of expansion and contraction due to moisture, the clearance fit can provide a certain buffer space for the dimensional changes of the bamboo unit strips 20 caused by changes in humidity, reducing the stress concentration caused by dimensional changes and avoiding problems such as cracking and deformation of the flooring.

[0040] Optionally, adjacent bamboo unit strips 20 are bonded together using adhesive. After the mortise and tenon joints of adjacent bamboo unit strips 20 are completed, an appropriate amount of adhesive is applied to the joint seams, ensuring the adhesive fully fills the gaps and penetrates the surface and interior of the bamboo unit strips 20. The adhesive can be, but is not limited to, phenolic resin, modified MUF, resorcinol, etc. After applying the adhesive, it is cured according to the adhesive's instructions until it is completely dry and cured, firmly bonding the adjacent bamboo unit strips 20 together. The adhesive's bonding effect further enhances the connection strength between adjacent bamboo unit strips 20, making the flooring a unified whole and improving its load-bearing capacity and impact resistance. Simultaneously, because the adhesive fills the joint seams, it forms a waterproof barrier, effectively preventing moisture from penetrating into the flooring, reducing problems such as swelling, deformation, and decay of the bamboo unit strips 20 caused by moisture, and extending the flooring's lifespan.

[0041] Optionally, when using the above-mentioned adhesive for width splicing and length extension, either high-frequency hot pressing or high-temperature hot pressing can be used. No specific limitations are specified in this solution.

[0042] Based on the above embodiments, referring to Figure 1 and Figure 2 Multiple bamboo unit strips 20 are stacked along the thickness direction DT2 of bamboo strip 10; tenons 21 extend along the thickness direction DT2 of bamboo strip 10. That is, the upper surface of the floor is the side surface of bamboo strip 10.

[0043] Based on the above embodiments, referring to Figure 3 and Figure 4 Multiple bamboo unit strips 20 are stacked along the width direction DW2 of the bamboo strip 10; tenons 21 extend along the width direction DW2 of the bamboo strip 10. That is, the upper surface of the floor is either the upper or lower surface of the bamboo strip 10.

[0044] According to the above scheme, bamboo unit strips 20 are allowed to be spliced ​​along the length direction DL1 and then connected along the thickness direction DT1 or the width direction DW1. For example, multiple bamboo unit strips 20 can be spliced ​​along the length direction DL1 to form a panel of a certain length, and then these panels can be spliced ​​along the thickness direction DT1 or the width direction DW1 to form a larger area of ​​flooring, making the entire floor more solid and reliable.

[0045] A shipping container includes a container body and the aforementioned flooring, the flooring being laid within the container body. The bamboo engineered wood flooring is designed and manufactured with full consideration of the internal dimensions of the container body. The width and length of the flooring are precisely cut and spliced ​​according to the effective space inside the container. Applying the aforementioned bamboo engineered wood flooring to shipping containers can significantly improve the overall performance of the containers. The high strength and stability of the flooring provide a reliable guarantee for the safe transportation of goods.
