Drawings

The high-strength plywood of the invention is further described with reference to the accompanying drawings and the specific embodiments.

Fig. 1 is a schematic view of a splicing structure of each layer of the high strength plywood of the present invention.

Detailed Description

As shown in figure 1, the high-strength plywood of the invention is formed by bonding nine layers of thin plates by glue, the surface layer 1 and the bottom layer 9 are integral single thin plates, namely the surface layer 1 and the bottom layer 9 are integral plates and do not need to be spliced, the smoothness of the surface and the integrity of each layer can be ensured by adopting the integral single thin plates, no splicing gap exists, the surface matching requirement of a template is met, and the high-strength plywood is beneficial to the working procedures of painting, polishing and the like.

As shown in figure 1, the second layer 2, the fourth layer 4, the seventh layer 7 and the ninth layer 9 are spliced by three identical thin plates in a transverse side-by-side mode, and splicing seams of the three thin plates are two vertical lines, so that the tensile strength in the longitudinal direction can be effectively increased.

As shown in fig. 1, the third layer 3 is formed by splicing five thin plates, the lower half part of the third layer 3 is formed by splicing two identical strip-shaped thin plates transversely side by side, the upper half part is formed by splicing three thin plates transversely side by side, the leftmost thin plate is the smallest plate of the three thin plates, and the other two thin plates are identical in size and are connected together side by side. Can effectually increase horizontal ascending tensile strength like this, adopt rectangular shape board and short slab to join in marriage each other moreover, can rationally and effectively utilize not unidimensional panel, reduce the waste material and produce, improve resource utilization.
