Description

Technical Field

[0001] This utility model relates to the field of flooring technology, and in particular to a bamboo-wood composite flooring. Background Technology

[0002] Containers, train carriages, and freight cars are widely used in various industries as transport containers to facilitate the turnover and transportation of goods and improve the efficiency of resource transportation.

[0003] Transport containers consist of multiple side panels, a top panel, and a floor. The floor needs to bear the weight of goods over a long period, withstand the friction during loading and unloading, and face risks such as moisture and slippage. Therefore, the floor must be made of materials with good pressure resistance, wear resistance, slip resistance, and waterproof properties.

[0004] In related technologies, most flooring structures are simple and made of a single material, resulting in low overall structural strength and load-bearing capacity. Utility Model Content

[0005] The purpose of this application is to provide a bamboo-wood composite flooring with high structural strength and good pressure resistance.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] According to one aspect of this application, a bamboo-wood composite flooring is provided, comprising: two surface layers, a core layer, and two connecting layers; the two surface layers are arranged vertically at intervals, each surface layer being formed by laying out multiple bamboo bundles after pressing and drying, the multiple bamboo bundles being arranged horizontally and parallel to each other along the grain direction; the core layer is disposed between the two surface layers, the core layer being formed by bonding together multiple core boards arranged vertically, the grain direction of the core boards being parallel to the grain direction of the bamboo bundles; the two connecting layers are arranged one-to-one with the two surface layers, the connecting layers being disposed between the corresponding surface layer and the core layer, each connecting layer comprising multiple connecting plates arranged vertically, the multiple connecting plates being arranged horizontally along the grain direction, and any two adjacent connecting plates within the same connecting layer having their grain directions staggered.

[0008] In some embodiments, the grain direction of any two adjacent connecting plates within the same connecting layer is perpendicular to each other; and / or, in any two adjacent connecting plates, the grain direction of one connecting plate is parallel to the grain direction of the bamboo bundle sheet in the adjacent surface layer.

[0009] In some embodiments, a plurality of the bamboo bundles are laid flat to form a panel, the panel constituting the surface layer.

[0010] In some embodiments, the thickness of the panel ranges from 3mm to 8mm; and / or, the surface layer is made from natural bamboo strips.

[0011] In some embodiments, the core board is formed by laying multiple bundles of bamboo strips flat; or, the core board is particleboard.

[0012] In some embodiments, the core board is oriented bamboo particleboard or oriented poplar particleboard.

[0013] In some embodiments, the thickness of the core layer ranges from 6 mm to 16 mm.

[0014] In some embodiments, among the plurality of connecting plates, at least one connecting plate is a bamboo veneer formed by laying multiple bamboo bundles flat, and at least one connecting plate is a wood veneer; the thickness of the connecting layer ranges from 1.5mm to 5.5mm.

[0015] In some embodiments, the wood veneer is a hardwood veneer.

[0016] In some embodiments, the thickness of the bamboo bundles in the bamboo-wood composite flooring ranges from 50% to 75% in the vertical direction.

[0017] As can be seen from the above technical solution, this application has at least the following advantages and positive effects:

[0018] In this application, the bamboo-wood composite flooring consists of two surface layers, two connecting layers, and a core layer. The grain directions of the two surface layers and the core layer are parallel, while the grain directions of the multiple connecting boards within the connecting layer are interlaced. This design allows the load-bearing capacity of the surface layer to be distributed through fibers with different grain directions. Furthermore, the interlacing and lamination of multiple layers results in a tighter connection between them, effectively improving the overall structural strength and load-bearing capacity of the flooring. Additionally, the two surface layers are formed by laying flat, pressed and dried bamboo bundles, thus improving the wear resistance of the surface layer and effectively reducing the likelihood of scratches and wear.

[0023] A transport container includes a top, a floor, and multiple side panels. The top, floor, and side panels enclose a transport space for accommodating goods. During transport, the floor bears the load, and friction occurs between the floor and the goods.

[0024] In related technologies, flooring not only suffers from a single structure and material, resulting in low structural strength and poor load-bearing capacity, but also from surface materials such as engineered wood and phenolic resin impregnated paper, which make the flooring surface easily scratched and worn, leading to poor durability.

[0025] Figure 1 This is a structural schematic diagram of the bamboo-wood composite flooring of this utility model.

[0026] See Figure 1 This application discloses a bamboo-wood composite flooring, comprising: two surface layers 100, a core layer 300, and two connecting layers 200. The two surface layers 100 are vertically spaced apart and are formed by laying multiple flat, pressed, and dried bamboo bundles, with the bundles arranged horizontally and parallel to each other along their grain direction. The core layer 300 is located between the two surface layers 100 and is formed by bonding multiple vertically arranged core boards, with the grain direction of the core boards parallel to that of the bamboo bundles. The two connecting layers 200 are arranged one-to-one with the two surface layers 100, and are positioned between the corresponding surface layer 100 and core layer 300. Each connecting layer 200 includes multiple vertically arranged connecting boards, which are arranged horizontally along their grain direction, with the grain directions of any two adjacent connecting boards within the same connecting layer 200 staggered.

[0027] Bamboo-wood composite flooring consists of two surface layers 100, two connecting layers 200, and a core layer 300. The grain direction of the two surface layers 100 and the core layer 300 is parallel, while the grain direction of the multiple connecting boards within the connecting layer 200 is interlaced. This interlacing of multiple layers results in a tighter connection between them, effectively improving the overall structural strength of the flooring and avoiding weaknesses in the cross-grain direction, thus enhancing its structural stability. When the surface layer 100 bears a load, the load is dispersed through the fibers of each layer, effectively improving the flooring's load-bearing capacity.

[0028] Furthermore, both surface layers 100 are formed by laying flat bamboo bundles after pressing and drying, which improves the wear resistance of the surface layer 100 and effectively reduces the likelihood of scratches and wear. At the same time, bamboo is low-carbon and environmentally friendly, and its wide availability means that the extensive use of bamboo in flooring effectively improves the environmental performance of the flooring and reduces its production costs.

[0029] See Figure 1 In this embodiment, the bamboo-wood composite flooring includes two surface layers 100 arranged vertically at intervals. The surface layer 100 is formed by laying out multiple flattened and dried bamboo bundles.

[0030] Bamboo tubes are vertically sliced, then spread, pressed, and dried to form bamboo bundles. After being impregnated with resin and dried, the bamboo bundles are assembled into layers to form a surface layer.

[0031] After precision pressing and high-temperature drying, the bamboo bundles do not require carbonization and retain their original state. The natural bamboo bundles fully utilize their toughness, effectively improving the load-bearing capacity and compressive strength of the surface layer 100.

[0032] It is understandable that the grain direction of bamboo strips and wood veneers is the same as the length direction of the bamboo and wood fibers during their growth. That is, the grain direction of bamboo strips is the same as the height direction of the bamboo, and the grain direction of wood veneers is the same as the height direction of the wood.

[0033] In some embodiments, the bamboo bundles are bamboo strips with the outer bamboo layer removed, thereby increasing the surface friction of the bamboo strips. When the outer bamboo layer of the bamboo bundle faces the connecting layer 200, removing the outer bamboo layer effectively increases the structural strength of the connection between the surface layer 100 and the connecting layer 200. When the outer bamboo layer of the bamboo bundle faces away from the connecting layer 200, removing the outer bamboo layer improves the anti-slip performance of the surface layer 100, facilitating the support of goods and ensuring their stability, preventing goods from sliding on the floor.

[0034] In some embodiments, the thickness of the flattened and dried bamboo bundles is 3mm to 8mm.

[0035] In this embodiment, multiple bamboo bundles are laid flat to form a panel, and the panel constitutes the surface layer 100.

[0036] The surface layer 100 consists of only one panel, which can reduce the thickness of the surface layer 100 while ensuring the structural strength, anti-slip performance and wear resistance of the surface layer 100, thereby reducing the thickness of the floor and increasing the volume of the transport space.

[0037] In some embodiments, the bamboo bundles within the same panel are parallel to the grain direction to improve panel strength, avoid internal stress caused by conflicting fiber directions, and control transverse deformation.

[0038] In some embodiments, the thickness of the surface layer 100 is the thickness of a single layer of bamboo strips. That is, the thickness of the surface layer 100 is 3mm to 8mm.

[0039] See Figure 1 In this embodiment, the two-layer 100 can be divided into a top layer 110 and a bottom layer 120, with the top layer 110 disposed on the upper side of the bottom layer 120.

[0040] In some embodiments, the top layer 110 and the bottom layer 120 may be symmetrically arranged relative to the core layer 300, such that the bamboo yellow surface of the top layer 110 and the bamboo yellow surface of the bottom layer 120 face each other, or the bamboo yellow surface of the top layer 110 and the bamboo yellow surface of the bottom layer 120 face away from each other.

[0041] In other embodiments, the bamboo shavings surface of the top layer 110 may face the connecting layer 200. The bamboo shavings surface of the bottom layer 120 may face or face away from the connecting layer 200.

[0042] See Figure 1 In this embodiment, the bamboo-wood composite flooring further includes two connecting layers 200. The two connecting layers 200 are respectively connected to the two surface layers 100 and located on opposite sides of the two surface layers 100, for connecting the two surface layers 100 and the core layer 300. On one hand, the connecting layers 200 can fully bond the surface layers 100 and the core layer 300, thereby effectively improving the connection strength between the surface layers 100 and the core layer 300. On the other hand, the connecting layers 200 can bear the load of the surface layers 100 and evenly distribute the load to the core layer 300, effectively improving the flooring's load-bearing capacity and preventing damage to the flooring surface due to excessive local load intensity.

[0043] See Figure 1 In this embodiment, the connecting layer 200 includes a plurality of connecting plates arranged vertically in sequence. The grain directions of any two adjacent connecting plates within the same connecting layer 200 are staggered. After bearing the load, the connecting plates bonded to the surface layer 100 transfer the load to the adjacent connecting plates, and the load is further dispersed and transferred through the bamboo fibers within the adjacent connecting plates, thereby effectively improving the load-bearing capacity and load dissipation capacity of the connecting layer 200.

[0044] In some embodiments, the grain direction of any two adjacent connecting plates within the same connecting layer 200 is perpendicular to each other, so that the load borne by the surface layer 100 can be evenly distributed through multiple connecting plates, thereby improving the load-bearing capacity of the connecting layer 200.

[0045] In some embodiments, in any two adjacent connecting plates, the grain direction of one connecting plate is parallel to the grain direction of the bamboo bundles of the adjacent surface layer 100, so that the load borne by the surface layer 100 can be evenly transferred to the core layer 300 after passing through multiple connecting plates, thereby improving the load dissipation capability of the connecting plates.

[0046] See Figure 1 In this embodiment, among the multiple connecting plates of the connecting layer 200, at least one connecting plate is a bamboo veneer formed by multiple bamboo bundles laid flat, and at least one connecting plate is a wood veneer, so that the connecting layer 200 is a bamboo-wood composite structure. This ensures the structural stability of the floor while guaranteeing the pressure-bearing capacity and load-dissipation capacity of the connecting layer 200, and reduces the production cost of the floor.

[0047] See Figure 1 In this embodiment, the connecting layer 200 includes two connecting plates, one of which is a wood veneer and the other is a bamboo veneer.

[0048] The adjacent panels and bamboo veneers are glued to the vertical sides of the wood veneer, and the core layer 300 is glued to the side of the bamboo veneer away from the wood veneer. This allows the load borne by the panels to be decomposed by the wood veneer and then transferred to the bamboo veneer, and finally transferred to the core layer 300 through the bamboo veneer. This can improve the connection strength between the various structural layers in the floor and ensure the structural strength of the floor.

[0049] In other embodiments, the grain direction of the wood veneer is perpendicular to the grain direction of the adjacent panel, and the grain direction of the bamboo veneer is parallel to the grain direction of the adjacent panel, so as to ensure sufficient contact between the wood veneer and the panel facing each other and improve the connection strength between the wood veneer and the panel. Furthermore, the bamboo veneer can also improve the load-bearing capacity and load-distribution capacity between the wood veneer and the core layer 300, thereby improving the structural strength of the flooring.

[0050] In other embodiments, the grain direction of the wood veneer is parallel to the grain direction of the adjacent panel, and the grain direction of the bamboo veneer is perpendicular to the grain direction of the adjacent panel, so that the panel load carried by the wood veneer can be evenly transferred to the core layer 300 after being decomposed by the bamboo veneer, thereby effectively ensuring the load decomposition capability of the connecting layer 200.

[0051] In some embodiments, bamboo veneer can be formed by bonding together the aforementioned raw bamboo bundles.

[0052] In some embodiments, the wood veneer may be a hardwood veneer.

[0053] In some embodiments, the wood veneer can be birch veneer, rubberwood veneer, etc. In other embodiments, the wood veneer can be other hardwood veneers, etc.

[0054] In some embodiments, the thickness of the wood veneer in the vertical direction ranges from 1.5 mm to 2.2 mm.

[0055] In some embodiments, the thickness of the connecting layer 200 in the vertical direction ranges from 1.5 mm to 5.5 mm. The thickness of the connecting layer 200 is a thickness parameter obtained by measuring the floor after cold pressing and / or hot pressing.

[0056] See Figure 1 In this embodiment, the two connecting layers can be an upper connecting layer 210 and a lower connecting layer 220, respectively. The upper connecting layer 210 is located above the lower connecting layer 220, and the layer structure in the upper connecting layer 210 and the layer structure in the lower connecting layer 220 are symmetrically arranged with respect to the core layer 300.

[0057] In some embodiments, from bottom to top, the lower connecting layer 220 is provided with wood veneer and bamboo splice in sequence, and the upper connecting layer 210 is provided with bamboo splice and wood veneer in sequence.

[0058] See Figure 1 In this embodiment, the bamboo-wood composite flooring includes a core layer 300. The core layer 300 is disposed between two connecting layers 200 to support the two connecting layers 200. The core layer 300 includes a plurality of core boards arranged vertically in sequence, and the plurality of core boards are bonded together in sequence.

[0059] In some embodiments, the core layer 300 includes a plurality of core boards, which can all be formed by laying out a plurality of the above-mentioned bamboo bundles, thereby effectively improving the environmental performance of the flooring, reducing the production cost of the flooring, and increasing the load-bearing capacity of the flooring.

[0060] In some embodiments, the core layer 300 includes a plurality of core boards, all of which may be particleboard, thereby effectively improving the stability of the floor.

[0061] In other embodiments, the core board is oriented bamboo particleboard or oriented poplar particleboard.

[0062] See Figure 1 In this embodiment, the thickness of the core layer 300 is in the range of 6mm to 16mm to ensure the thickness of the core layer 300, thereby enabling the core layer 300 to fully bear the load transmitted by the surface layer 100 and the connecting layer 200, and to ensure the structural stability and reliability of the floor.

[0063] In some embodiments, the grain direction of the multiple core boards is parallel to the grain direction of the bamboo bundles in the surface layer.

[0064] See Figure 1 In this embodiment, the thickness ratio of bamboo bundles in the bamboo-wood composite flooring is 50% to 75% in the vertical direction, so as to increase the proportion of bamboo in the bamboo-wood composite flooring, effectively ensure the environmental performance of the flooring, and reduce the production cost of the flooring.

[0065] See Figure 1 In this embodiment, the flooring, from bottom to top, comprises a bottom layer 120, a lower connecting layer 220, a core layer 300, an upper connecting layer 210, and a top layer 110. The bottom layer 120 is constructed by neatly splicing multiple bamboo bundles horizontally to ensure no gaps between any two adjacent bamboo bundles. Next, the wood veneer of the lower connecting layer 220 is laid first, followed by the bamboo plywood of the lower connecting layer 220. Then, multiple core boards are laid. Next, the bamboo plywood and wood veneer of the upper connecting layer 210 are laid sequentially. Finally, multiple bamboo bundles are laid to form the top layer 110. After all layers of the flooring are laid, it is hot-pressed using a hot press to form the flooring.

[0066] In some embodiments, when the bamboo bundles are hot-pressed after being impregnated with adhesive, the adhesive will seep out of the bamboo bundles to bond them to the adjacent board structures, thereby forming an adhesive layer between them, which improves the connection strength and structural stability of the floor.

[0067] In other embodiments, adhesive can be used to bond the various board structures within the floor to form an adhesive layer, thereby further improving the bonding strength of the various board structures within the floor and enhancing the structural stability of the floor.

[0068] In this embodiment, the perimeter of the floor can also be trimmed and tenoned to form a prefabricated tenon and mortise structure, which facilitates the splicing and interlocking of the floor with other external structures, thereby increasing the applicability of the floor.

[0069] See Figure 1 This application provides a bamboo-wood composite board, which, from bottom to top, comprises a face panel, a wood veneer, a bamboo splice, multiple core boards, bamboo splices, wood veneers, and the face panel again. When the face panel bears a load, it distributes the load to the wood veneers intersecting in the same grain direction. After bearing pressure, the wood veneer is evenly transferred to the core boards through the bamboo splices. The load borne by the core boards is further distributed and transferred to the bottom wood veneers and the bottom face panel through the bamboo splices, thereby enabling the load of goods to be evenly distributed through multi-stage transmission, effectively improving the load-bearing capacity and pressure resistance of the floor, preventing damage to the floor due to excessive local pressure, and improving the structural strength and stability of the floor.

[0070] Furthermore, the surface layer 100 of the floor is made of bamboo strips, which has high hardness and good toughness, thereby improving the wear resistance of the floor surface and effectively reducing the possibility of the floor surface being scratched or worn.

[0071] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
