Description

Technical Field

[0001] This utility model relates to the field of bamboo-based wood-based panels, specifically a bamboo-wood structural panel. Background Technology

[0002] Wood boards are panels made from whole pieces of wood. Most existing wood boards are made from a single piece, but these boards have poor compressive strength perpendicular to the board's direction and are prone to warping and breakage. Therefore, when purchasing wood boards, it's crucial to carefully examine the grain; ideally, avoid boards with broken grain, as these are more susceptible to breakage. Bamboo boards, on the other hand, are made from finely processed bamboo strips that are glued and pressed together. The process involves dozens of steps, including sawing, slicing, rough planing, high-temperature steaming, high-pressure carbonization, drying, fine planing, color sorting, assembly, pressing, and sanding. Bamboo boards have advantages such as a low water absorption and expansion coefficient, resistance to cracking, and resistance to warping. However, they also suffer from poor compressive strength perpendicular to the board's direction. Therefore, an improved technology is urgently needed to address this problem in existing technologies. Summary of the Invention

[0003] The purpose of this utility model is to provide a bamboo and wood structural board that improves structural strength and stability, whether perpendicular to the direction of the structural board or in the plane direction of the structural board, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a bamboo and wood structural board, comprising bamboo strips, long wooden blocks, and short wooden blocks. Several bamboo strips are arranged in parallel. A row of long wooden blocks is provided between adjacent bamboo strips, and the long wooden blocks in the same row are interconnected. Long wooden blocks located on both sides of the same bamboo strip are arranged alternately. A short wooden block is provided between two adjacent bamboo strips at one end. The inner side of the short wooden block is connected to the corresponding long wooden block. The wood grain of both the long and short wooden blocks is perpendicular to the arrangement direction of the bamboo strips. The sides of the long and short wooden blocks are respectively connected to the sides of two adjacent bamboo strips.

[0005] Preferably, in the bamboo and wood structural board provided by this utility model, the long wooden blocks in the same column are connected by adhesive, and the short wooden blocks are connected to the adjacent long wooden blocks by adhesive.

[0006] Preferably, the bamboo and wood structural board provided by this utility model is wherein the long wooden blocks and the short wooden blocks are respectively connected to the corresponding bamboo strips on both sides by adhesive.

[0007] Preferably, in the bamboo and wood structural board provided by this utility model, the upper and lower surfaces of the long wooden blocks, short wooden blocks and bamboo strips are flush.

[0008] Preferably, the bamboo and wood structural board provided by this utility model has the length of the bamboo strip equal to an integer multiple of the length of the long wooden block plus the sum of the lengths of the short wooden blocks, and the length of the long wooden block is twice the length of the short wooden block.

[0009] Compared with the prior art, the beneficial effects of this utility model are: The overall structure adopts an alternating splicing structure of bamboo strips and wooden blocks, and the wood grain of the long and short wooden blocks is perpendicular to the direction of the bamboo strips. Whether perpendicular to the direction of the structural board or the plane direction of the structural board, the structural strength and stability are improved. At the same time, the two rows of long wooden blocks on both sides of the same bamboo strip are arranged alternately, which further improves the structural strength and stability of the structural board in the plane direction.

[0013] Please see Figure 1-3This utility model provides a technical solution: a bamboo and wood structural board, including bamboo strips 1, long wooden blocks 2, and short wooden blocks 3. Several bamboo strips 1 are arranged in parallel. A row of long wooden blocks 2 is provided between adjacent bamboo strips 1, and the long wooden blocks 2 in the same row are connected to each other. The long wooden blocks 2 in the same row are connected by adhesive. Short wooden blocks 3 are connected to adjacent long wooden blocks 2 by adhesive, thereby achieving connections between long wooden blocks 2 and between long wooden blocks 2 and short wooden blocks 3. Long wooden blocks 2 located on both sides of the same bamboo strip 1 are arranged alternately. A short wooden block 3 is provided between two adjacent bamboo strips 1 at one end. The inner side of the short wooden block 3 is connected to the corresponding long wooden block 2. The wood grain of both the long wooden blocks 2 and the short wooden blocks 3 is the same as that of the bamboo strips 1. The arrangement directions are perpendicular to each other. The sides of the long wooden blocks 2 and the short wooden blocks 3 are connected to the sides of the two adjacent bamboo strips 1 respectively. The long wooden blocks 2 and the short wooden blocks 3 are connected to the corresponding bamboo strips 1 on both sides by adhesive to achieve the connection between the long wooden blocks 2 and the short wooden blocks 3 and the corresponding bamboo strips 1. The upper and lower surfaces of the long wooden blocks 2, the short wooden blocks 3 and the bamboo strips 1 are flush to ensure the flatness of the surface of the structural board. The length of the bamboo strip 1 is equal to an integer multiple of the length of the long wooden block 2 plus the length of the short wooden block 3 to ensure the flatness of the surfaces at both ends of the structural board. The length of the long wooden block 2 is twice the length of the short wooden block 3, so that the long wooden blocks 2 in adjacent columns are staggered and the staggered positions are located at the midpoint of the long wooden blocks 2 respectively.

[0014] Processing method and principle: First, several bamboo strips 1, long wooden blocks 2 and short wooden blocks 3 are made. The bamboo strips 1 are pressed and shaped at high temperature. One side of the bamboo strip 1 is connected to several long wooden blocks 2 with adhesive. The long wooden blocks 2 are also connected with each other with adhesive. Then, the end of the long wooden block 2 away from the first bamboo strip 1 is connected to another bamboo strip 1 with adhesive. The empty part at the end of the first row of long wooden blocks 2 is filled with a short wooden block 3. The short wooden block 3 is connected to the bamboo strip 1 and the adjacent long wooden block 2 with adhesive. Next, the second row of long wooden blocks 2 is installed, staggered with the first row of long wooden blocks 2, and connected to the corresponding bamboo strips 1 with adhesive. Then, short wooden blocks 3 are connected to the corresponding bamboo strips 1 and long wooden blocks 2 with adhesive. The short wooden blocks 3 in the second row and the short wooden blocks 3 in the first row are located at both ends of the structural board. Then, the above steps are repeated, and bamboo strips 1 and long wooden blocks 2 are installed in sequence, so that the adjacent rows of long wooden blocks 2 are staggered. The short wooden blocks 3 fill the empty parts at the ends of the corresponding rows. After bottling, the structural board is placed in the molding and pressing mold. The structural board is shaped by high temperature and pressure. After the adhesive solidifies, the bamboo and wood structural board is obtained. Finally, the surface, ends and sides are polished to complete the processing. This utility model has a reasonable structure. The whole adopts a splicing structure of bamboo strips 1 and wooden blocks in an alternating manner. The wood grain of the long wooden blocks 2 and the short wooden blocks 3 is perpendicular to the arrangement direction of the bamboo strips 1. Whether perpendicular to the direction of the structural board or the plane direction of the structural board, the structural strength and stability are improved. At the same time, the two rows of long wooden blocks 2 located on both sides of the same bamboo strip 1 are arranged in an alternating manner, thereby further improving the structural strength and stability of the structural board in the plane direction.
