Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the scope of protection of the present utility model.

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] A lightweight plywood with a wooden assembly structure includes a bottom panel 1 and a top panel 2. An edge banding strip 3 is provided between the bottom panel 1 and the top panel 2. Two sets of vertical strips 4 and two sets of horizontal strips 5 are provided on the inner side of the edge banding strip 3, connected end-to-end to form a square frame. Wood adhesive is applied to the top and bottom surfaces of the square frame to bond the top panel 2 and the bottom panel 1 to both sides of the frame. The square frame fits inside the edge banding strip 3. Three sets of geometric panels 6 are provided on the bottom panel 1, inside the edge banding strip 3. Both sides of the plate 2 are provided with insertion holes 7. Fixing members 8 are provided on the upper plate 2 at the two sets of insertion holes 7. Positioning holes 9 are also provided on both sides of the upper plate 2. Positioning members 10 are provided on the upper plate 2 at the two sets of positioning holes 9. An injection hole 11 is provided in the middle of a set of horizontal strips 5. After the layer board bonding process is completed, foaming material can be filled into the interior of the layer board through the injection hole 11 to improve the support strength of the layer board. A detachable plug is provided at the corresponding position of the sealing strip 3 to seal the injection hole 11.

[0028] Furthermore, positioning grooves 12 adapted to positioning members 10 are provided on the inner side of both sets of horizontal bars 5 to improve the positioning effect. Fixing grooves 13 adapted to fixing members 8 are also provided on the inner side of both sets of horizontal bars 5 to further improve the shelf positioning effect.

[0029] Furthermore, the type 6 includes a strip-shaped plate body 61, which is hollow and has a lightweight function. Positioning strips 62 are provided on both sides of the top of the plate body 61, which can make stable contact with the upper panel 2 and improve the connection effect. Through holes 63 are provided on both sides of the plate body 61, so that the filling material can be transferred in the internal space of the plate and can fill more positions inside the plate.

[0030] Furthermore, an identification card 14 is provided on the top panel 2 to identify the information of the shelf.

[0031] The implementation principle of this embodiment is as follows:

[0032] First, assemble the frame: vertical strip 4 and horizontal strip 5 are joined together with mortise and tenon to form a rectangular frame, and wood glue is applied to both sides of the frame;

[0033] Then the panel is encapsulated: the lower panel 1 is pre-installed with a type plate 6, the upper panel 2 is coarsely positioned by inserting the positioning piece 10 into the positioning groove 12, and the fixing piece 8 is embedded in the fixing groove 13 to achieve final locking.

[0034] Finally, the foaming process is carried out: foaming material (expansion ratio 1:8) is injected through injection hole 11 and a three-dimensional support network is formed through the through hole 63 of the shaped plate.

[0035] After the shelf is formed, its functions can be expanded: identification cards 14 are hot-pressed in to record data such as production batch and load-bearing level.
