[0021] The technical solution of the present application will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0022] The present application embodiment discloses a high-strength, compression-resistant solid wood composite door. Figure 1 and Figure 2A high-strength, compression-resistant solid wood composite door includes a door leaf, wherein the door leaf includes a frame 1 and a door core 2 installed in the frame 1. To improve the compression strength of the door core 2, according to the principle of bridge hole mechanics, a plurality of circular holes 3 are provided through the door core 2, so that the length direction of the holes 3 is consistent with the height direction of the door leaf, and the plurality of holes 3 are evenly spaced along the width direction of the door leaf, ensuring that the door core 2 has a strong compression resistance along its thickness direction. At the same time, the provision of the plurality of holes 3 also makes it difficult for cracks to occur on the surface of the door core 2 when thermal expansion and contraction occur, further ensuring the overall compression resistance of the door core 2.

[0023] Reference Figure 2 and Figure 3 , a plurality of support plates 4 are installed in the hole 3 on the door core 2, the length direction of the support plates 4 is consistent with the length direction of the hole 3, and the two sides of the support plates 4 are pressed against the inner wall of the hole 3, so that the support plates 4 can stably support the inner wall of the hole 3. In order to make the support plates 4 in the hole 3 be evenly stressed, the center of the hole 3 is located on the support plates 4, so that the support plates 4 can divide the hole 3 equally. According to the principle of triangle stability, in the embodiment of the present application, two support plates 4 are provided in a hole 3, and a notch 7 is opened in the middle of the support plates 4. The two support plates 4 are vertically plugged through the notch 7 to form a cross structure, so that the two support plates 4 can stably support the inner wall of the hole 3 in the hole 3, thereby evenly dividing the hole 3 into four sectors, and the shape of the sectors is similar to a triangle, so that the inner wall of the hole 3 can maintain a stable state under the support of the two vertically plugged support plates 4, thereby improving the compressive strength of the door core 2.

[0024] Since the two support plates 4 are connected by vertical insertion through the notch 7, in order to avoid the notch 7 on the support plate 4 from being damaged, thereby affecting the stability of the connection between the two support plates 4, refer to Figure 3 and Figure 4 , a reinforcing plate 8 is installed on the support plate 4 at the notch 7, and each notch 7 corresponds to two reinforcing plates 8; the reinforcing plate 8 includes a U-shaped portion and two extensions, the U-shaped portion is stably buckled on the side wall of the notch 7 through a sealant, and the two extensions extend from the two flanges of the U-shaped portion, respectively, so that the two extensions are located outside the notch 7, and the two extensions are tightly attached to the surfaces of both sides of the support plate 4 through the sealant. Two support plates 4 with reinforcing plates 8 are vertically plugged and connected, and the reinforcing plates 8 can improve the strength of the notch 7 of the support plate 4, so that the two support plates 4 can be stably plugged.

[0025] To further improve the stability of the connection between the two support plates 4, refer to Figure 3 and Figure 4A fastening assembly for stably locking the two support plates 4 is provided between the two support plates 4. In the embodiment of the present application, the fastening assembly includes a plurality of right-angle plates 9 and screws 10 for fixing the right-angle plates 9 to the reinforcing plates 8; the plurality of right-angle plates 9 are arranged at intervals along the length direction of the support plates 4, and the two sides of the right-angle plates 9 are respectively tightly fitted with the reinforcing plates 8 on the two vertically inserted support plates 4. The screws 10 penetrate the right-angle plates 9 and are threadedly connected with the reinforcing plates 8, so that the two support plates 4 are stably connected together under the joint action of the plurality of right-angle plates 9. In other embodiments, the fastening assembly may be a plurality of triangular ribs welded between two vertically arranged reinforcing plates 8.

[0026] Since the side edge of the support plate 4 is pressed against the inner wall of the hole 3, in order to avoid pressure loss on the inner wall of the hole 3, refer to Figure 2 , Figure 3 and Figure 5 , a buffer layer is arranged on the inner wall of the hole 3, and the buffer layer can be a sponge layer, a damping pad 5, or a rubber layer. In the embodiment of the present application, the buffer layer is arranged as a damping pad 5. A plurality of adhesive layers 6 are arranged on the inner wall of the hole 3 between the damping pad 5, and the plurality of adhesive layers 6 are spaced and distributed between the inner wall of the hole 3 and the damping pad 5, which not only enables the damping pad 5 to be stably installed on the inner wall of the hole 3, but also the damping pad 5 has a certain ductility, so that the damping pad 5 can adapt to the thermal expansion and contraction of the inner wall of the hole 3. The edge of the support plate 4 is arranged to be an arc shape that fits the inner wall of the hole 3, so that when the support plate 4 is pressed against the inner wall of the hole 3 through the damping pad 5, the support plate 4 will not cause pressure loss to the damping pad 5, thereby extending the service life of the damping pad 5.

[0027] The implementation principle of a high-strength, compression-resistant solid wood composite door in the embodiment of the present application is as follows: when manufacturing a solid wood composite door, the door core 2 is first processed to form a plurality of holes 3, and then the damping pads 5 are stably bonded to the inner walls of the holes 3 through a plurality of adhesive layers 6. Then, a plurality of support plates 4 are vertically plugged in pairs and fixedly connected through fastening components, and at the same time, a plurality of groups of assembled support plates 4 are respectively inserted into a plurality of holes 3, so that the sides of the support plates 4 are pressed against the inner walls of the holes 3 through the damping pads 5, thereby achieving stable support for the holes 3. Finally, the door core 2 is fixedly installed in the frame 1 to form a door leaf.

[0028] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
