Description

[Technical field]

[0001] The utility model relates to the technical field of decoration boards, in particular to a full-bamboo multilayer board. [Background technology]

[0002] At present, there are many all-wood panels on the market, including wooden floors and wooden wall panels. With the strengthening of forest resource protection, the production of all-wood panels is decreasing. Bamboo grows fast and will not damage forest resources. Therefore, panels made of bamboo materials have gradually become a substitute for all-wood panels. However, bamboo floors and bamboo wall panels are mostly made of bamboo strips. This type of panel cannot fully meet the actual use requirements in terms of strength, hardness, nail holding force, and service life. Bamboo floors are easily deformed after long-term use, so their service life is short; bamboo wall panels with poor nail holding force are directly nailed to the wall, and they are easy to loosen after long-term use, which may cause the wall panels to deform, shake or make abnormal sounds, or even fall apart, thus affecting the safety and service life of the wall panels.

[0003] In view of this, the inventor of this case conducted in-depth research on the above-mentioned issues, which led to the emergence of this case. [Contents of the utility model]

[0004] The utility model aims to solve the technical problems in the prior art and provides a full bamboo multilayer board which will not deform after long-term use, has high safety and long service life and can be used to manufacture bamboo floors or bamboo wallboards.

[0005] The utility model is realized as follows: a full bamboo multilayer board comprises a heavy bamboo layer, a core layer, and a bamboo bottom layer, wherein one side of the core layer is glued to the heavy bamboo layer, and the other side is glued to the bamboo bottom layer; the core layer comprises at least two longitudinal bamboo layers and at least one transverse bamboo layer, and the longitudinal bamboo layers and the transverse bamboo layers are stacked up and down in an alternating manner.

[0006] Furthermore, the sum of the number of layers of the longitudinal bamboo layers and the transverse bamboo layers is any one of 3 layers, 5 layers, and 7 layers.

[0007] Furthermore, the longitudinal bamboo layer is formed by gluing a plurality of longitudinal bamboo strips side by side; and the transverse bamboo layer is formed by gluing a plurality of transverse bamboo strips side by side.

[0008] Furthermore, the thickness of the heavy bamboo layer, the bamboo bottom layer, the longitudinal bamboo layer and the transverse bamboo layer are all 1-3 mm.

[0009] Furthermore, the lengths of the heavy bamboo layer, the bamboo bottom layer, the longitudinal bamboo layer and the transverse bamboo layer are all 244 mm and the widths are all 122 mm.

[0010] Furthermore, the longitudinal bamboo layer is formed by 4-8 longitudinal bamboo strips glued side by side; and the transverse bamboo layer is formed by 2-4 transverse bamboo strips glued side by side.

[0011] The advantages of the utility model are: the core layer is designed to be composed of multiple longitudinal bamboo layers and transverse bamboo layers stacked and glued in an alternating manner, thereby ensuring the longitudinal and transverse tear resistance of the core layer; when used to produce bamboo wall panels, the core layer has a high nail holding force, which can increase the overall strength of the bamboo wall panels and ensure that the bamboo wall panels are not deformed or loosened; when used to produce bamboo floors, the core layer has a high compressive resistance, and the bamboo floors will not collapse after long-term use.
