JP3084517U - Laminated board using plant stem as core material - Google Patents

Abstract

(57) [Summary] (Modifications required) [Problem] To reduce the environmental destruction, reduce the weight, and improve the soundproofing effect by using unnecessary stalks of plants such as wheat and high beams in a girder and using it as a core material. The present invention relates to a laminated wooden board. SOLUTION: An unnecessary vegetable wood stalk girder braided layer 2 coated with an adhesive is placed on an upper part of a wooden veneer layer 1, and a wooden veneer layer 1 is further placed thereon. The three layers are compressed while regulating the thickness.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a wooden laminated board using dried vegetable wood stalks such as wheat and Takahashi for the second layer of a three-layer board.

[0002]

[Prior art]

 Conventionally, three-layer boards are generally called plywood, and all three layers are produced by cutting down woody natural resources. None of them is thicker than 30 mm. It was not a layer but a five or more layered board, which was heavy and difficult to transport, and had problems in processing and handling. All layers used forest resources that had been cut down, leading to the destruction of the global environment.

[0003]

[Problems to be solved by the invention]

 Except for its drawbacks, the present invention aims to develop a wood laminate that is less harmful to the environment and that is thicker than 30 mm despite being three layers, yet lightweight.

[0004]

[Means for Solving the Problems]

 The solution will be described with reference to the drawings as follows. (B) Collect the unnecessary and discarded stalks after harvesting wheat, takahashi, and other fruits cultivated on farmland, etc., and dry them sufficiently. (B) Cut a sufficiently dried stem into a predetermined length. (C) Pass the stems one by one through a gluing roll coater, and apply sufficient adhesive to each stem. (D) The stems coated with the adhesive are laid one by one on the first layer of wood veneer (1) having a thickness of 1 mm to 2 mm, and are spread all over the girder from end to end (2). Then, the wooden veneer (1) of the same thickness is placed again. However, it is preferable that an adhesive is applied to one side of the first and third layers of the wood veneer (1) that touches the stem. (E) The above three layers are compressed by a high-pressure hot press from above and below, but in order to regulate the thickness of the compressed laminate, a thickness regulating jig that surrounds four sides of the laminated laminate for regulating thickness is used. I need.

[0005]

[Embodiment of the invention]

 With the above structure, the use of woody natural materials is extremely reduced, the earth environment is protected, the thick boards can be cut lightly and any part can be cut, and the middle layer is shaped like a girder with stems. Since it is rare, it is a wooden laminate with a soundproofing effect due to the presence of many cavities.

[0006] In implementing the present invention, the following is possible. (A) Since it has a soundproofing effect, it can be used as a floor base material or a partition material. (B) Light weight allows easy transportation.

[0007]

[Effect of the invention]

 Therefore, it is possible to significantly reduce the use of woody natural resources, and because it is lightweight, it can be easily transported and carried in even when used in high-rise buildings, etc. is there.
