[0029] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0030] like Figures 1-6 As shown, the multi-layer composite pine plywood provided in this embodiment includes a core layer 1. Decorative layers 2 are provided on both the upper and lower surfaces of the core layer 1. Through grooves 3 are provided on all four sides of the core layer 1. Strip boxes 4 are installed inside each of the through grooves 3. Insect repellent is filled inside each strip box 4. An opening 5 is provided at one end of each strip box 4. Several slots 6 are evenly distributed on the side walls of each strip box 4, and insert plates 7 are installed inside each slot 6. By setting strip boxes 4 around the core layer 1 and placing insect repellent in them, termites and other pests can be prevented from damaging the core layer 1. Furthermore, since the strip boxes 4 are located around the core layer 1, they do not affect the structural strength of the core layer 1. The openings 5 ​​facilitate the filling of insect repellent, and the insert plates 7 divide the insect repellent, preventing it from leaking out completely if the strip boxes 4 are partially damaged. It should be noted that the insect repellent used in this application is a powder insect repellent, such as boric acid powder.

[0031] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, a waterproof layer 8 is provided on the side of the decorative layer 2 away from the core board layer 1. The waterproof layer 8 is provided to prevent the core board layer 1 from getting damp.

[0032] In this embodiment, as Figure 1 , Figure 3 and Figure 5 As shown, the core board layer 1 has vertically arranged first serrations 9 and second serrations 10 on both its upper and lower surfaces. The decorative layer 2 has a third serration 11 that cooperates with the first serration 9 and a fourth serration 12 that cooperates with the second serration 10 on its side near the core board layer 1. By setting the first serration 9, the second serration 10, the third serration 11, and the fourth serration 12, the connection efficiency between the core board layer 1 and the decorative layer 2 is improved, preventing them from falling off when subjected to force at any angle in the horizontal direction.

[0033] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the front half of one side outer wall of the core board layer 1 is provided with a tenon 13, and the rear half is provided with a mortise 14. The tenon 13 and the mortise 14 can fit together. The front half of the other side outer wall of the core board layer 1 is provided with a mortise 14, and the rear half is provided with a tenon 13. By providing the tenon 13 and the mortise 14, the connection is tighter and easier to install and remove. Moreover, the connection can only be made in one direction, so it will not fall off when subjected to a force along the connection direction, but will only fall off when subjected to the opposite force.

[0034] In this embodiment, as Figure 1 , Figure 3 and Figure 4 As shown, the tenon 13 has a mounting groove 15, and a spring 16 is installed inside the mounting groove 15. One end of the spring 16 is connected to a retaining ball 17. The tenon 13 has a retaining hole 18 that mates with the retaining ball 17. In its natural state, half of the retaining ball 17 is located inside the mounting groove 15. By setting the spring 16, retaining ball 17, and retaining hole 18, when connecting the core board layer 1, the retaining ball 17 is engaged in the retaining hole 18 under the action of the spring 16. Therefore, when subjected to a force opposite to the installation direction, it can prevent it from falling off to a certain extent.

[0035] In this embodiment, as Figures 1-6 As shown in the figure, the working process of a multi-layer composite pine plywood provided in this embodiment is as follows:

[0036] By setting strip boxes 4 around the core board layer 1 and placing insect repellent in the strip boxes 4, termites and other pests can be prevented from damaging the core board layer 1. Furthermore, since the strip boxes 4 are positioned around the core board layer 1, they do not affect the structural strength of the core board layer 1. Openings 5 ​​facilitate the filling of insect repellent, and insert plates 7 can divide the insect repellent, preventing it from leaking out completely if the strip boxes 4 are partially damaged. A waterproof layer 8 prevents the core board layer 1 from getting damp. The first sawtooth 9, the second sawtooth 10, the third sawtooth 11, and the fourth sawtooth 12 improve the appearance and finish of the core board layer 1. The connection efficiency of layer 2 prevents it from falling off when subjected to force at any angle in the horizontal direction. The tenon 13 and mortise 14 make the connection tighter and easier to install and remove. It can only be connected in one direction, so it will not fall off when subjected to force along the connection direction, but will only fall off when subjected to the opposite force. The spring 16, ball 17 and locking hole 18 are provided. When connecting core board layer 1, the ball 17 is locked into the locking hole 18 under the action of the spring 16. Therefore, when subjected to force opposite to the installation direction, it can prevent it from falling off to a certain extent.
