Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present invention, "a plurality" means two or more unless specifically limited otherwise.

In the embodiments of the present invention, unless otherwise explicitly specified or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, e.g., as being fixedly connected, detachably connected, or integrated; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. Specific meanings of the above terms in the embodiments of the present invention can be understood by those of ordinary skill in the art according to specific situations.

In an embodiment of the present invention, as shown in fig. 1, a stable high performance unidirectional plywood is provided, which includes a plurality of board layers sequentially stacked from bottom to top; each of the sheet layers comprises at least two veneers 10; two single boards 10 which are arranged between adjacent layers and are in contact with each other are bonded through glue; two single boards 10 which are arranged between adjacent layers and are in contact with each other are arranged in a staggered manner.

Specifically, the single boards 10 of each layer are all laid in sequence along the length direction, the multiple single boards 10 between adjacent layers are bonded and pressed together through glue, and the two single boards 10 which are in contact between the adjacent layers are arranged in a staggered manner, that is, in the vertical direction, any single board 10 spans two single boards 10 on the upper layer and/or the lower layer to cover the gap and the splicing seam between the two single boards 10. Thus, the continuity between two adjacent single boards 10 in each layer is increased, and the overall strength is improved.

In another embodiment of the present invention, all the single boards 10 are arranged along the grain in the same direction. Particularly, the arrangement is beneficial to improving the maximum tensile strength and the maximum compressive strength of the stable high-performance equidirectional plywood; secondly, can effectively reduce the influence that timber expend with heat and contract with cold brought, reduce veneer 10 shrink limit degree promptly to avoid final finished product to scrap because of the size is not enough, be favorable to saving the resource.

In another embodiment of the utility model, the total number of the sheet layers is 13-17.

Specifically, this stable form high performance syntropy plywood adopts the 10 range upon range of formation of veneers that thickness is 1.5 ~ 2.5mm, in this embodiment, the total number of piles of layer on sheet layer is 15 layers, and all veneers 10's thickness is unanimous, and after the repeated experiment of a lot of, when sheet layer piles up to 15 layers, its bulk strength is enough to deal with most operational environment's demand. When the number of the layers is less than 15, the strength is insufficient, and when the number of the layers is more than 15, resources are wasted, so that the arrangement of 15 layer plates is beneficial to improving economic benefits and cost performance.

In another embodiment of the utility model, the total number of layers of the sheet material is an odd number; the board layer closest to the ground is taken as the 1 st layer, the board layer farthest from the ground is taken as the topmost layer, and glue is coated on the upper surface and the lower surface of the single board 10 on the even layers. The glue is applied to the even layers, and the glue is not applied to the odd layers, so that the glue consumption is reduced, the resource is saved, and the overflow caused by the contact and extrusion of the two layers of glue can be avoided. When the total number of layers of the board layers is an odd number, the board layer positioned on the highest layer is not coated with glue, so that the surface roughness and glue falling of the board layer on the uppermost layer can be avoided, and the attractiveness is improved.

In another embodiment of the present invention, the material of the veneer 10 is poplar or pine. In particular, the wood of the poplar and the pine has high toughness and strength and high bearing capacity, and in addition, the poplar and the pine have natural color and luster and clear and beautiful texture and are very suitable for manufacturing furniture.

In another embodiment of the present invention, all the single boards 10 on the outermost board layer are provided with a plurality of grooves with upward openings; all the grooves together form a predetermined pattern.

Specifically, in this embodiment, the shape of each groove is different, and all grooves are the bottom surface that runs through place veneer 10 to in avoiding glue to get into the groove, influence pleasing to the eye, in addition, also avoid setting up the bonding area reduction between the veneer 10 of notched and the adjacent level, lead to setting up the veneer 10 of notched and drop. All the grooves together form a pattern which is set according to the needs of the user. So, demonstrate the pattern through setting up a plurality of recesses, improved this stable form high performance syntropy plywood's pleasing to the eye greatly, be favorable to promoting marketing.

In another embodiment of the utility model, bosses are embedded in all the grooves; the shape of each boss is matched with the shape of the corresponding groove; the top surfaces of all the bosses protrude out of the groove.

Specifically, each boss and each recess respectively one-to-one, and inlay the adaptation each other to avoid external dust to pile up in the recess, when reducing the aesthetic feeling, be difficult to wash. In this embodiment, the grooves have the same depth, the bosses have the same height, and the bosses have a height greater than the depth of the grooves, so that the bosses protrude from the grooves after the mounting. The design is to increase the stereoscopic impression and touch feeling of the stable high-performance homodromous plywood. In addition, the accumulation of external dust in the groove can be avoided. It is worth mentioning that, compare in direct carving pattern on veneer 10, the mode is inlayed to the boss that provides in this embodiment, is favorable to improving the price/performance ratio of this stable form high performance syntropy plywood, and can also avoid the material extravagant, and its mainly embodies: when any one or more bosses are damaged, they can be removed and replaced with new ones.

In another embodiment of the present invention, all of the bosses are painted with paint. Specifically, the artistry and the ornamental value of the stable high-performance homodromous plywood can be improved by coating the pigment on the outer surface of the boss. Further, the pigment used is a fluorescent pigment, so that it can be noticed by the user even at night or in an environment where light is weak. In addition, through using fluorescent pigment, can also avoid the user to bump with this stable form high performance syntropy plywood by accident, played the effect of protection user.

In another embodiment of the utility model, the glue is a mixed glue of virgin glue and strong flour. Specifically, the high gluten flour is added into the virgin rubber, so that the bonding strength is improved, and meanwhile, the waterproof performance is improved. In addition, the stable high-performance equidirectional plywood is not easy to absorb moisture.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
