Description

New LTTL structural plywood

technical field

The utility model belongs to the technical field of decorative boards, in particular to a novel LTTL structural plywood.

Background technique

At present, plywood is mostly made of wooden veneers with criss-cross and symmetrical structures, which are bonded by adhesives. The criss-cross and adhesive bonding make people lack the feeling of thick solid wood when they see conventional plywood. Not environmentally friendly enough, the overall design is not reasonable enough.

In order to improve the existing technology, people have carried out long-term exploration and proposed various solutions. For example, Chinese patent literature discloses a new type of plywood [Application No.: CN201220224575.8], which includes laminated multilayer veneers, and is characterized in that it also includes at least one line layer, and the line layer is arranged on the corresponding Between two adjacent veneers.

Although the above-mentioned solution solves the deficiencies of the prior art to a certain extent, the plywood lacks the feeling of thick solid wood, too many glue layers in the plywood are not environmentally friendly, and the overall design is not reasonable enough.

Utility model content

The purpose of this utility model is to provide a kind of reasonable in design, the novel LTTL structural plywood of simple structure for above-mentioned problem.

In order to achieve the above object, the utility model adopts the following technical solutions: the new LTTL structural plywood comprises a core board composed of 2 or 3 middle boards, and the middle boards are glued to each other by an adhesive, and It is characterized in that panels are glued on the upper and lower sides of the core board respectively, the direction of the wood texture of the middle boards of each layer is the same, the direction of the wood grain of each panel is the same, and the direction of the wood grain of the middle board is the same as that of the middle board. The wood grain direction of the panels is not the same. The wood texture of each middle board is in the same direction, and the middle board is thicker. Although the middle board is glued by adhesive, it is not easy to see in appearance. From the senses, the core board composed of the middle boards will be regarded as a thick wooden board. In effect, it has the effect of a solid wood board, and is more environmentally friendly. The overall design is reasonable and the structure is simple.

L in LTTL is the abbreviation of English Longitudinal, L means vertical, T is the abbreviation of Transverse, T means horizontal, LTTL means vertical and horizontal staggered arrangement.

In the above-mentioned novel LTTL structural plywood, the thickness of the middle boards of each layer is 2-12mm.

In the above-mentioned novel LTTL structural plywood, the outer surface of at least one panel is pasted with impregnated film paper. The surface of the plywood with impregnated film paper is paint-free and more environmentally friendly.

In the above-mentioned novel LTTL structural plywood, at least one side of the plywood is provided with an edge strip. At least one side of the plywood is provided with an edge band, which is stronger and more durable, saves carpentry time for decoration, improves efficiency, and improves the quality of decoration products.

In the above-mentioned novel LTTL structural plywood, the wood grain direction of the middle board is perpendicular to the wood grain direction of the panel.

In the above-mentioned novel LTTL structural plywood, the wood grain direction of the middle board is longitudinal wood grain, and the wood grain direction of the panel is transverse wood grain.

In the above-mentioned novel LTTL structural plywood, the direction of the wood grain of the middle board is the transverse wood grain, and the wood grain of the panel is the longitudinal wood grain.

In the above-mentioned new LTTL structural plywood, a veneer 7 is arranged between the panel 3 and the impregnated film paper 4, and the thickness of the veneer 7 is 0.2-1.0mm.

Compared with the prior art, the utility model has the advantages of:

First, the wood textures of the middle boards are in the same direction, and the middle boards are thicker. Although the middle boards are glued together by adhesive, it is not easy to see from the outside. From the senses, the core board composed of the middle boards will be regarded as a thick wooden board. , in terms of visual effect, it has the effect of solid wood board, and is also more environmentally friendly. It has higher strength than block board, the overall design is reasonable, and the structure is simple.

Second, the surface of plywood with impregnated film paper is paint-free and more environmentally friendly.

Thirdly, at least one side of the plywood is provided with an edge band, which is stronger and more durable, and also saves carpenter's decoration time, improves efficiency, and improves the quality of decoration products.

detailed description

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

Example 1

As shown in Figure 1, the novel LTTL structural plywood comprises a core plate 6 composed of 2 or 3 layers of intermediate plates 1, and the intermediate plates 1 of each layer are glued to each other by an adhesive 2, and it is characterized in that the core plate 6 Panels 3 are glued on the upper and lower sides by adhesive 2 respectively. The direction of the wood texture of the middle board 1 of each layer is the same, the direction of the wood grain of each panel 3 is the same, and the direction of the wood grain of the middle board 1 is different from the direction of the wood grain of the panel 3. Similarly, the thickness of each intermediate plate 1 is 2-12mm. The wood textures of the middle boards 1 are in the same direction, and the middle board 1 is relatively thick. Although the middle boards are glued by the adhesive 2, it is not easy to see from the outside, and the core board 6 composed of the middle boards 1 will be regarded as a thick layer in the sensory sense. Wooden boards have more visual effects like solid wood boards and are more environmentally friendly. The overall design is reasonable and the structure is simple.

Wherein, the wood grain direction of the middle board 1 is perpendicular to the wood grain direction of the panel 3 . More specifically, the wood grain direction of the middle board 1 is the longitudinal wood grain, and the wood grain of the panel 3 is the horizontal wood grain; or the wood grain direction of the middle board 1 is the horizontal wood grain, and the wood grain of the panel 3 is the vertical wood grain.

Example 2

As shown in FIG. 2 , this embodiment is basically the same as Embodiment 1, the difference is that at least one panel 3 is pasted with an impregnated film paper 4 on the outer surface. The surface of the plywood with impregnated film paper 4 is paint-free and more environmentally friendly.

Example 3

As shown in Figure 3, this embodiment is basically the same as Embodiment 2, the difference is that at least one side of the plywood is provided with an edge strip 5, which is more firm and durable, saves carpenter's decoration time, improves efficiency, and Improve the quality of decoration products.

Example 4

As shown in Figure 4, this embodiment is basically the same as Embodiment 2, the difference is that a veneer 7 is arranged between the panel 3 and the impregnated film paper 4, and the thickness of the veneer 7 is 0.2-1.0 mm.
