Further, it will be appreciated that the dimensions of the various elements shown in the figures are not drawn to scale, for ease of description, and that the thickness or width of some layers may be exaggerated relative to other layers, for example.

It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined or illustrated in one of the figures, it will not need to be further discussed or illustrated in detail in the description of the figures that follows.

As shown in fig. 1-3, the utility model provides a technical solution: a silk-added reinforced plywood comprises a central veneer layer 1, wherein two central veneer layers 1 are arranged and bonded together, the upper end surface of the upper central veneer layer 1 and the lower end surface of the lower central veneer layer 1 are both bonded with a silk-added reinforcing layer 3, the upper end surface of the upper silk-added reinforcing layer 3 and the lower end surface of the lower silk-added reinforcing layer 3 are both bonded with an outer veneer layer 4, the fiber directions of the central veneer layer 1 and the outer veneer layers 4 are in cross distribution, the upper end surface of the upper outer veneer layer 4 is bonded with an anti-skid layer 5, the top of the anti-skid layer 5 is provided with anti-skid lines, the lower end surface of the lower outer veneer layer 4 is bonded with a waterproof layer 6, it is noted that the central veneer layer 1 and the outer veneer layers 4 are both made of wood single layers, the cross distribution of the fiber directions of the plywood is used for enabling the plywood to have higher strength, and the wood fibers between different layers have the function of mutual restriction, prevent its fracture, the setting of 5 top anti-skidding lines on skid resistant course for the people adds here when walking on the silk strengthens the plywood, can not take place to slide, reduces the possibility of falling down.

As a specific embodiment, the inside of the two central veneer layers 1 is respectively provided with the reinforcing glue grooves 2 distributed in a cross manner, and the two reinforcing glue grooves 2 are communicated with each other, it should be noted that after the two central veneer layers 1 are bonded by the adhesive, reticular glue is formed at the reinforcing glue grooves 2 distributed in a cross manner, and after the reticular glue is solidified, the reticular glue is acted on the reinforcing glue grooves 2 at the inside of the two central veneer layers 1, so that the adhesive force between the two central veneer layers 1 is stronger, and the separation of the two central veneer layers 1 due to degumming is avoided when the silk-added reinforced plywood is bent.

As a specific example, the reinforced ply-yarn layer 3 includes a central fixing sheet 301, the top and bottom of the central fixing sheet 301 are fixedly connected with a transverse reinforced ply-yarn 302 and a longitudinal reinforced ply-yarn 303 respectively, the top and bottom of the transverse reinforced ply-yarn 302 and the bottom of the longitudinal reinforced ply-yarn 303 are fixedly connected with an outer connecting sheet 304, the outer connecting sheet 304 is adhered with the central ply-yarn 1 and the outer ply-yarn 4, it should be noted that the central fixing sheet 301, the transverse reinforced ply-yarn 302, the longitudinal reinforced ply-yarn 303 and the outer connecting sheet 304 are glued together by adhesives, the adhesives filled between the central fixing sheet 301 and the outer connecting sheet 304 fix the transverse reinforced ply-yarn 302 and the longitudinal reinforced ply-yarn 303, when the reinforced ply-yarn veneer is bent transversely, the transverse reinforced ply-yarn 302 is pulled, and a force resisting the transverse bending is simultaneously applied to the central fixing sheet 301 and the outer connecting sheet 304, so that the bending degree of the reinforced ply-yarn veneer is reduced, when the reinforced plywood with the wire added in the same sample is longitudinally bent, the wire added 303 is dragged to provide a force for resisting the longitudinal bending for the central fixing sheet 301 and the outer side connecting sheet 304, and the fracture caused by excessive bending due to overlarge stress of the reinforced plywood with the wire added is avoided.

As a specific example, waterproof layer 6 includes adsorbed layer and water-resistant layer, the adsorbed layer is located water-resistant layer top, water-resistant layer top is provided with the drain pipe, it should be explained that water-resistant layer can keep out the moisture that comes from this adds silk and strengthen the plywood bottom, avoid ligneous center veneer layer 1 and outside veneer layer 4 to wet and be corroded, the effect of adsorbed layer is to adsorb a small amount of moisture in center veneer layer 1 and the outside veneer layer 4, and discharge through the drain pipe, the water resistance of this adds silk and strengthens plywood has been improved.

In this embodiment, when this adds silk and strengthens plywood and takes place the bending, at first under the effect of the netted colloid of crossing distribution in the middle of two center veneer layers 1, two center veneer layers 1 can not break the glue and separate, in addition, the effect of dragging of transversely adding silk 302 and vertically adding silk 303 has reduced this and has added the bending angle of strengthening plywood of silk, has reduced because of the cracked possibility of bending, has effectively improved the bending strength of plywood.

It should be noted that, through the arrangement of the wire-added reinforcing layer 3, the transverse wire 302 and the longitudinal wire 303 are distributed in a crossed manner and fixed together through the central fixing sheet 301, and are connected with the central veneer layer 1 and the outer veneer layer 4 through the outer connecting sheet 304, when the plywood is transversely bent, the transverse wire 302 is under the traction action of the longitudinal wire 303, when the plywood is longitudinally bent, the transverse wire 302 and the longitudinal wire 303 are under the traction action of the longitudinal wire 303, so that the force required for breaking the plywood is larger, and the bending resistance of the plywood is improved.

In addition, the arrangement of the crossed reinforced glue grooves 2 between the two central veneer layers 1 enables the adhesive glue filled in the grooves to form a net structure, so that the adhesive capacity is higher, the two central veneer layers are prevented from being separated due to bending, and the strength of the plywood is further improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
