[0027] The plate body 1 is composed of a group of panel boards 101, core boards 102, a group of fiber layers 103 and a group of waterproof layers 104. The group of fiber layers 103 are respectively arranged on both sides of the core board 102, the group of waterproof layers 104 are respectively arranged on the group of fiber layers 103, and the group of panel boards 101 are respectively arranged on the group of waterproof layers 104. By adding the waterproof layer 104 and the fiber layer 103, the plate body 1 performs better in terms of moisture-proof, corrosion-resistant and wear-resistant.

[0028] The material of the core board 102 is oriented strand board, and the waterproof layer 104 adopts thermoplastic polyolefin waterproof coiled material. By using the oriented strand board as the material of the core board 102, the plate body 1 has higher strength and stiffness in the longitudinal direction, and can meet the use requirements under various complex working conditions.

[0029] First edge boards 2 are arranged on both sides of the plate body 1. A connecting plate 5 and a connecting rod 6 are respectively installed on one side of the two first edge boards 2. A connecting groove 12 is opened on one side of the connecting plate 5, and the connecting groove 12 is adapted to the connecting rod 6. Through the double-sided edge wrapping design and the firm connection of the connecting plate 5 and the connecting rod 6, the stability of the composite plywood plate body 1 is significantly enhanced. This structure can effectively resist external impacts and vibrations, and prevent the plate body 1 from deforming or being damaged.

[0030] Connecting grooves are opened on one side of the first edge board 2 and the connecting plate 5. The two connecting grooves are arranged oppositely. A connecting block 7 is installed in the connecting groove of the first edge board 2. The connecting block 7 is in sliding contact with the connecting groove on the connecting plate 5. A fixing bolt is installed on the connecting block 7 in a threaded manner, and the fixing bolt is threadedly connected with the connecting plate 5. By using the combination of the connecting groove, the connecting block 7 and the fixing bolt, the connection between the first edge board 2 and the connecting plate 5 becomes more stable and reliable, preventing the connection from loosening or falling off.

[0031] Second edge boards 8 are arranged on both sides of the plate body 1. Clamping plates 9 are installed on the two second edge boards 8. The two clamping plates 9 are clamped with each other. A second colloid 10 is coated on the two edge boards 8 and the two clamping plates 9. The multiple second colloids 10 are in close contact with the plate body 1, the two edge boards 8 and the two clamping plates 9 respectively. Through the design of the second edge board 8 and the clamping plate 9, the appearance of the plate body 1 becomes more neat and beautiful.

[0032] Installation grooves are opened on one side of the second edge boards 8. The two installation grooves are arranged oppositely. An installation block 11 is installed in any one of the installation grooves. A connecting bolt is installed on the installation block 11 in a threaded manner, and the connecting bolt is threadedly connected with the other installation groove. By using the combination of the installation groove, the installation block 11 and the connecting bolt, the connection between the second edge boards 8 becomes more stable and reliable.

[0033] The working principle of the composite plywood provided by the present utility model is as follows:

[0034] The first edge board 2 and the second edge board 8 wrap the side edges of the board body 1 to reduce the exposed area of the side edges and prevent the direct erosion of the internal structure of the board body by the external environment (such as moisture, humidity, corrosive substances, etc.). At the same time, the first colloid 4 and the second colloid 10 are used to install the first edge board 2 and the second edge board 8, which is relatively fast to install and also plays a sealing role, further preventing the external environment from invading the internal part of the board body through the gaps, thereby improving the overall protection performance of the board body 1. By adding the waterproof layer 104 and the fiber layer 103, the board body 1 performs better in terms of moisture resistance, corrosion resistance and wear resistance. At the same time, the multi-layer structure design enables the board body 1 to more effectively disperse stress when bearing loads, thereby improving its overall strength and stability;

[0035] The core board 102 is made of oriented strand board, so that the core board 102 has high strength and stiffness in the direction of the grain, and can effectively bear and disperse the loads from the board surface. The waterproof layer 104 is made of thermoplastic polyolefin waterproof coiled material, which has good waterproof performance, weather resistance and chemical stability, and can effectively block the intrusion of moisture and other harmful substances. At the same time, the thermoplastic polyolefin waterproof coiled material also has certain flexibility and plasticity, which is convenient for construction and installation;

[0036] Through the mutual cooperation of the connecting plate 5 and the connecting rod 6, the two first edge boards 2 are firmly connected together, and then the two board bodies 1 are spliced. This connection method is also convenient for installation and disassembly, improving the construction efficiency. By rotating the connecting bolt, it can be tightly threadedly connected with another installation groove, thereby firmly connecting the two second edge boards 8 together to assemble the two board bodies 1. This fastening method is not only simple and fast, but also has high connection strength and stability.

[0037] Compared with the related technologies, the composite plywood provided by the present utility model has the following beneficial effects:

[0038] The utility model provides a composite plywood. Through the combination of the first edge board 2 and the connecting board 3, and the sealing effect of the first colloid 4, the exposed area of the side of the board body is effectively reduced, and the erosion of the internal structure of the board body 1 by the external environment is significantly reduced, thereby prolonging the service life of the board body 1. By adding the waterproof layer 104 and the fiber layer 103, the board body 1 performs better in moisture-proof, corrosion-resistant and wear-resistant aspects. By using the oriented strand board as the core board 102 material, the board body 1 has higher strength and stiffness in the longitudinal direction, and can meet the use requirements under various complex working conditions. Through the double-sided edge wrapping design and the firm connection of the connecting board 5 and the connecting rod 6, the stability of the composite plywood board body 1 is significantly enhanced. This structure can effectively resist external impacts and vibrations, and prevent the board body 1 from deforming or being damaged;

[0039] Through the combined use of the connecting groove, the connecting block 7 and the fixing bolt, the connection between the first edge board 2 and the connecting board 5 becomes more stable and reliable, preventing the connection from loosening or falling off. Through the design of the second edge board 8 and the clamping board 9, the appearance of the board body 1 becomes neater and more beautiful. Through the combined use of the mounting groove, the mounting block 11 and the connecting bolt, the connection between the second edge boards 8 becomes more stable and reliable.
