[0002] Plywood is a three-layer or multi-layer board material made by peeling wood segments into veneers or planing wood blocks into thin wood, and then gluing them with adhesives. It is usually made of an odd number of veneers, with the fibers of adjacent veneers glued perpendicular to each other. As a common building material, plywood has been widely used in construction projects. However, traditional plywood often deforms and cracks when subjected to greater pressure, which seriously affects its service life and safety.

[0008] Preferably, the support layer is formed by connecting multiple layers of board materials by bonding, and two adjacent board materials are arranged in a crisscross pattern according to the wood grain direction of the board materials themselves.

[0009] Preferably, each layer of plate material in the support layer is made of high-strength and high-toughness material.

[0010] Preferably, the compression-resistant buffer component comprises two buffer layers, the top side and the bottom side of the core plate are both bonded with buffer layers, and the sides of the two buffer layers that are away from each other are respectively bonded and connected to the corresponding support layers.

The selection of high-strength and high-toughness materials further enhances its compression resistance effect. The settings of the compression-resistant buffer assembly and the support and buffer assembly not only provide a buffering effect but also maintain the relative stability of the structure, preventing the occurrence of situations such as damage to the plywood caused by relative side-sliding between the two support layers. Finally, the addition of the protective coating enhances the anti-corrosion and wear-resistant properties of the plywood and extends its service life.

[0022] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Referring to Figures 1-3 , a compression-resistant plywood includes a core board 1 and two support layers 2. The two support layers 2 are respectively arranged on the upper and lower sides of the core board 1. Buffer layers 3 are bonded to both the top side and the bottom side of the core board 1. The mutually remote sides of the two buffer layers 3 are respectively adhesively connected to the corresponding support layers 2, which can provide a certain buffering effect when the support layers 2 are under pressure. A plurality of limit blocks 4 are fixedly installed on the mutually close sides of the two support layers 2. A plurality of limit holes 5 are formed in the core board 1. The plurality of limit blocks 4 all penetrate through the buffer layers 3 and are respectively inserted and installed in the corresponding limit holes 5, which can keep the two support layers 2 in good relative stability, thereby avoiding situations such as side slip during actual use. Buffer blocks 8 are filled in the limit holes 5. The buffer blocks 8 are abutted against the corresponding limit blocks 4 and buffer layers 3, and the side of the buffer block 8 away from the limit block 4 is fixedly connected to the corresponding buffer layer 3 by adhesion, which can further improve the compression resistance. Anti-corrosion layers 6 are painted on the mutually remote sides of the two support layers 2. Wear-resistant layers 7 are painted on the sides of the anti-corrosion layers 6 away from the support layers 2, which can not only extend the service life of the plywood but also effectively prevent damage caused by friction during use.

[0024] In this embodiment, in order to improve the overall strength of the support layer 2, the support layer 2 is formed by bonding multiple layers of boards, and adjacent two boards are arranged vertically and horizontally in the direction of the wood grain of the board itself.

[0025] In this embodiment, in order to effectively disperse the external force and thus improve the compression resistance of the plywood, each layer of the board in the support layer 2 is made of a material with high strength and high toughness.

[0026] Working principle: During actual use, when the compressive plywood is subjected to an external force, the two support layers 2 are the first to bear the force. Since the support layer 2 is formed by bonding multiple layers of high-strength and high-toughness plates, and the adjacent two plates are arranged vertically and horizontally according to the grain direction of the plates themselves, it can effectively disperse the external force, thereby improving the compressive performance of the plywood. At the same time, the buffer layer 3 can provide a certain buffering effect, further increasing the compressive performance of the plywood. In addition, the setting of the limit block 4 and the limit hole 5 can keep the two support layers 2 in good relative stability, avoiding situations such as side slip during actual use that may cause damage to the plywood. The setting of the buffer block 8 can cooperate with the limit block 4 to further enhance the compressive effect of the plywood. The setting of the anti-corrosion layer 6 and the wear-resistant layer 7 can not only extend the service life of the plywood but also effectively prevent damage caused by friction during use.

[0027] The above has introduced in detail a compressive plywood provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
