TECHNICAL FIELD
[0001] The utility model relates to bamboo wood class panel technology field especially bamboo wood structure panel. BACKGROUND
[0002] For a long time, furniture class panel mostly adopts wood to make, because wood has many advantages, but wood also has the characteristic of "shrinkage and expansion with moisture", because: the wood fiber of wood can exist the phenomenon of transverse shrinkage (when drying) or expansion (when being wet), and the panel made of wood also can exist such situation, so this can bring inconvenience to the application of pure wood panel, because the "shrinkage and expansion with moisture" phenomenon of wood can make wood deform (size and shape change), cause the laid wood board to partially bulge and crack. SUMMARY
[0003] The utility model solves the technical problem that provides a bamboo wood structure panel to solve the problem proposed in the background art.
[0004] The utility model adopts the technical scheme that a bamboo wood structure panel is formed by wood strips with wood fibers in longitudinal texture and bamboo strips with bamboo fibers in longitudinal texture being spliced in an interlaced manner along the width direction of both, wherein the width H of the wood strip is 2-6cm, the width h of the bamboo strip is 0.6-1.2cm, and the thickness of both is consistent; in the length direction of both, the wood strips are spliced with the wood strips, and the bamboo strips are spliced with the bamboo strips, and the joint of the wood strips and the joint of the bamboo strips are distributed in a staggered manner.
[0005] Further, the splicing of the wood strips and the bamboo strips, the wood strips and the wood strips, and the bamboo strips and the bamboo strips all adopts the mode of gluing.
[0006] A bamboo wood structure panel with a multi-layer structure is formed by stacking and combining a plurality of the bamboo wood structure panels as described above, the length direction of each layer of the bamboo wood structure panels is consistent, and the wood strips and the bamboo strips of the adjacent two layers of the bamboo wood structure panels are stacked in a staggered manner.
[0007] Further, the stacking and combining of the above multi-layer bamboo wood structure panels all adopts the mode of gluing.
[0008] The beneficial effects of this utility model are as follows: This bamboo-wood structural board, by using bamboo strips (whose coefficient of shrinkage and expansion is much lower than that of wood) spliced with narrow (smaller width) wooden strips, effectively avoids deformation due to shrinkage and expansion, thus improving the board's application quality. Furthermore, because the board contains bamboo strips, and bamboo's fiber density and bending strength are greater than wood's, this board has better application effects and a wider range of applications compared to ordinary pure wood boards. Moreover, since the wooden strips are primarily made from thinner and shorter pieces of wood, a large amount of sawn-off scraps from round logs can be processed for secondary use, thereby saving significant amounts of wood resources, greatly reducing product costs, and improving the product's cost-effectiveness. Attached Figure Description
[0009] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0010] Figure 1 This is a schematic diagram (three-dimensional view) of the single-layer bamboo and wood structural panel of this utility model;
[0011] Figure 2 This is a schematic diagram (three-dimensional view, double-layer structure) of the multi-layer bamboo and wood structural board of this utility model.
[0012] In the picture: 1. Wooden strip; 2. Bamboo strip. Detailed Implementation
[0013] A type of bamboo and wood structural panel, such as Figure 1 As shown, it is made by alternating strips of wood (1) with longitudinal wood fiber grain and strips of bamboo (2) with longitudinal bamboo fiber grain along their width. The width H of wood strip 1 is 2-6 cm, and the width h of bamboo strip 2 is 0.6-1.2 cm. Both have the same thickness. Along their length, wood strip 1 is joined to wood strip 1, and bamboo strip 2 is joined to bamboo strip 2. The joints of wood strip 1 to wood strip 1 and bamboo strip 2 to bamboo strip 2 are staggered to avoid affecting the structural strength of the finished board. The joints of wood strip 1 to bamboo strip 2, wood strip 1 to wood strip 1, and bamboo strip 2 to bamboo strip 2 are all made by gluing.
[0014] The shrinkage and expansion coefficients of various materials are different. Wood will deform (dimension and shape change, the same below) due to "dry shrinkage and moisture expansion". The deformation degree of the board is related to the shrinkage and expansion coefficients, and is also related to the size of the single board. Generally speaking, the greater the width (lateral dimension) of the single board, the greater the deformation degree caused by shrinkage. Therefore, by reducing the width (lateral dimension) of the wood strip, the deformation of the single wood strip caused by shrinkage can be reduced to a negligible degree. According to calculation and test, the width of the wood strip is controlled to 2-6 cm to achieve this effect. The wood strip with this width is spliced with thin bamboo strips in an interlaced manner. Because the shrinkage and expansion coefficient of bamboo is much smaller than that of wood, the deformation of the bamboo-wood spliced structure board caused by dry shrinkage and moisture expansion can be reduced to a completely negligible degree, so that the board can achieve very ideal effect in use.
[0015] The bamboo-wood spliced structure of the board not only solves the problem of "dry shrinkage and moisture expansion", but also improves the overall fiber density and bending strength of the board, thereby improving the use effect, expanding the application range of the board, saving a large amount of wood resources, greatly reducing the cost of the board product, and improving the performance-price ratio of the product.
[0016] A bamboo-wood structure board with a multi-layer structure, as shown in Figure 2 , is formed by laminating a plurality of bamboo-wood structure boards as described above. The length directions of the bamboo-wood structure boards are consistent, and the wood strips 1 and the bamboo strips 2 of adjacent two bamboo-wood structure boards are laminated in a staggered manner to not affect the structural strength of the finished board. The laminated combination between the multi-layer bamboo-wood structure boards is achieved by gluing.
[0017] In actual application, if the thickness of the single-layer bamboo-wood structure board cannot meet the requirements, the multi-layer bamboo-wood structure board can be used to meet the application requirements.
[0018] In addition, the bamboo-wood structure board of the present application can also be used as the core material of solid wood composite flooring and other application boards, thereby forming a composite board with better use performance or a certain specific function.
[0019] The above embodiments are only used to explain the present application, and are not limited to the protection of the present application. Any non-substantial modification based on the essential scheme of the present application shall fall within the protection scope of the present application.
