Therefore, it is not limited to the words and phrases described in the specification, and can be appropriately replaced according to the circumstances.

[0028] The utility model discloses a method for preparing a side pressure plate 100, such as Figure 1 As shown, the method includes collecting a plurality of hollow cylindrical bamboo tubes; cutting the bamboo tubes along a longitudinal plane to form a plurality of bamboo strips; bonding the cross sections of the plurality of bamboo strips to each other and laying them on a flat plane into a roughly rectangular shape to serve as an intermediate layer; bonding the surfaces of the plurality of bamboo strips to each other and laying them on a flat plane into a roughly rectangular shape to serve as an upper layer and a lower layer; and then laminating the upper layer and the lower layer to give them a more compact structure, bonding the upper layer to the upper surface of the intermediate layer, bonding the lower layer to the lower surface of the intermediate layer, laminating the upper layer, the intermediate layer and the lower layer to finally form a compact side pressure plate 100, and sealing the side pressure plate 100 to prevent dirt from entering the cross-sectional gap of the plate, and also to prevent moisture in the air from entering the plate, thereby preventing the plate from getting damp and making the plate more beautiful.

[0029] In other embodiments (not shown in the figure), edge banding can be performed using an edge banding machine or an iron, and the edge banding strip with glue on the back is heated and pasted on the side of the board, and the excess edge banding strip is removed. In other embodiments (not shown in the figure), laser edge banding can also be used for edge banding. The laser converges the high-energy laser beam onto the laser edge banding strip through a reflector that swings back and forth. The high-energy laser quickly melts the functional layer of the edge band to achieve laser edge banding.

[0030] In this embodiment, the root and tip of the bamboo are cut off to retain the middle part, and the bamboo is cut into a plurality of hollow cylindrical bamboo tubes. Before the cross sections of the plurality of bamboo strips are bonded to each other, the plurality of bamboo strips are carbonized and dried, and then planed and polished to have a smooth surface, making the subsequent production process simpler. The upper and lower panels are subjected to side pressure treatment respectively to make the connection more firm and less prone to cracking. The placement direction of the bamboo strips of the middle panel is transverse to the placement direction of the bamboo strips of the upper and lower panels to make it have a more stable structure. The bonded bamboo panels are then pressed and the edges and corners are treated to have a tighter structure and less prone to cracking. At the same time, the appearance is more beautiful and can effectively prevent users from being injured during use.

[0031] The utility model also discloses a side pressure plate 100, such as Figure 2 As shown, the first layer board 1000 and the third layer board 2000 are included, and the second layer board 3000 is arranged between the first layer board 1000 and the third layer board 2000 .

[0032] In this embodiment, if Figure 3 As shown, the first layer board 1000, the second layer board 3000 and the third layer board 2000 are all composed of a plurality of square boards 1001, wherein Figure 4 As shown, the square plate 1001 has two cutting surfaces 1002, and the cutting surfaces 1002 of a plurality of square plates 1001 are bonded together to form the second layer of plate 3000, wherein the cutting surface 1002 is a cross section formed by cutting the hollow bamboo tube longitudinally, and has a rectangular structure.

[0033] In this embodiment, the square plate 1001 also includes two long sides 1003, and the long sides 1003 of multiple square plates 1001 are bonded to each other to form a first layer of board 1000 and a second layer of board 2000, respectively, wherein the long side 1003 has a rectangular structure, and the two long sides 1003 are arranged opposite to each other and are relatively perpendicular to the cutting surface 1002.

[0034] In wood processing and production, the side pressing process is a common way to press wood strips. The wood strips are accurately placed at the position where they need to be pressed, and the pressing plates are placed on the upper and lower sides of the wood strips respectively to ensure that the pressing plates are in close and stable contact with the wood strips to provide uniform lateral pressure. The pressing plates can also be fixed to the wood strips with clamps or bolts. Pressure is applied through clamps, bolts or other tools to allow the pressing plates to apply lateral pressure to the wood strips. The pressure needs to be maintained for a fixed period of time until the wood strips are fully cured to ensure the pressing effect. After the curing time is completed, the pressure is released, the clamps or bolts are removed, and the pressing plates are removed from the wood strips to complete the side pressing.

[0035] In this embodiment, the first layer board 1000 and the third layer board 2000 are subjected to side pressure treatment after bonding respectively. The side pressure treatment can improve the connection strength between the multiple square plates 1001 and increase the firmness of the connection, so that the first layer board 1000 and the third layer board 2000 are firmly connected and not easy to crack.

[0036] In other embodiments (not shown in the figures), the second layer board 3000 after bonding is subjected to side pressure treatment to make it have a more stable structure.

A threaded hole is provided on the long side surface 1003 of the square plate 1001, wherein the threaded hole has a diameter slightly smaller than the diameter of the screw. The diameter of the hole is slightly smaller than the diameter of the screw. A screw is inserted into another adjacent square plate 1001 and screwed into the square plate 1001 with a screwdriver, so that multiple square plates 1001 are fixedly connected to form a first layer of plate 1000 and a third layer of plate 2000. The screwing direction of the screw is perpendicular to the grain direction of the square plate 1001 to ensure the firmness of the connection. The head of the screw is flush with the surface of the square plate 1001, making the first layer of plate 1000, the second layer of plate 3000 and the third layer of plate 2000 more beautiful.
