Abstract

<P>PROBLEM TO BE SOLVED: To achieve the weight reduction of a composite board while keeping the strength necessary as a floor panel of a truck. <P>SOLUTION: This composite board for the floor panel of the truck is constituted by integrally laminating at least two hard woody veneer layers on both sides of a core material comprising an OSB (oriented strand board) obtained by orienting cut wood pieces in a definite direction so that all of the fiber directions of the veneer layers become same to the orientation direction of the OSB. By this constitution, the floor panel can be reinforced by allowing the orientation direction of the OSB to coincide with the length direction of the floor panel of the truck and the number of horizontal common joists can be reduced. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a wood composite board used as a floor board of a truck.

  Conventionally, as a floor material of a truck, a plywood obtained by bonding and integrating high-strength, high-specific gravity South Sea wood single plates such as Apiton and Capol so that the fiber directions cross each other is used. However, because timber harvesting restrictions have been implemented for the purpose of protecting the global environment, not only the circulation of southern seawood has decreased, but also the production of large-diameter trees required for veneer production has decreased. Prices continue to rise. In addition, South Sea materials such as Apiton and Capol have a high specific gravity, so that the use of South Sea wood plywood has the drawback that the truck bed weight increases. Therefore, various wood materials that can be used as substitutes for the South Sea plywood have been proposed.

For example, Japanese Utility Model Laid-Open No. 7-13669 presents a vehicle flooring material in which medium-sized fiberboard, particle board, oriented particle board, etc. are used as core materials, and cross laminates of southern hard wood are laminated and integrated on both sides. Has been. According to the present invention, waste wood flakes and wood fibers can be used as a raw material for the core material, which is excellent in economy and resource saving. Moreover, since these core materials have a smaller specific gravity than the South Sea wood plywood, the weight of the cargo bed can be reduced. Furthermore, wear resistance and strength can be increased by laminating and integrating the cross laminates of southern hard wood on both sides of the core material.
Japanese Utility Model Publication No. 7-13669

  By the way, as shown in FIG. 2, the horizontal joists 11 are passed to the truck bed A at appropriate intervals in the width direction. The larger the bending strength in the length direction of the floor board 10 is, the more the horizontal joists 11 are spaced. The number of spread joists can be reduced, and the weight of the loading platform can be reduced. However, in the prior art, a cross plywood, that is, a plywood in which the fiber directions are orthogonal to each other is used as the surface layer material, so that the bending strength in the length direction of the flooring 10, that is, the fiber direction, cannot be said to be sufficient. .

  In the present invention, the problem to be solved is to reduce the weight while maintaining the strength required as a flooring material for trucks.

  In the present invention, an OSB (Oriented Strand Board) formed by orienting wood chips in a certain direction is used as a core material, and at least two hard wood veneer layers are formed on both sides of the OSB. The most important feature is that they are laminated and integrated so that they all have the same fiber direction.

  The composite plate for a truck floor board of the present invention has excellent “bending strength in the length direction”, which is the most important performance when applied to a truck bed, so that the number of horizontal joists in the bed can be reduced. This makes it possible to reduce the weight of the loading platform.

  In addition, since OSB is adopted as the core material, softwood, small-diameter wood, waste wood, and the like can be used as the raw material for the wood chip, which is excellent in economic efficiency and resource saving. Furthermore, the surface layer is made of two or more high-strength, high-specific gravity South Sea wood veneers, such as Apiton and Capol, and the same OSB orientation and fiber direction are laminated, so water resistance, wear resistance, surface smoothness, etc. It is a material that combines the physical performance required for truck floor boards.

  Examples of the composite plate according to the present invention will be described below together with comparative examples.

(Example) As shown in FIG. 1, the composite board of this example uses two single plates (tree species: Apton) 1a and 1b having a thickness of 2 mm for the surface layer material 1, and the core material 2 is sanded on both sides. Using the OSB having a thickness of 9 mm (manufactured by KRONOPOL, Poland, tree species: Scots pine), the surface material 1 was attached to both sides of the core material. In addition, it laminates | stacks so that the fiber direction of the surface side single plate 1a and the core material side single plate 1b and the wood chip orientation direction of a core material may become substantially parallel, and adhere | attach using a phenol resin adhesive, A composite plate with a thickness of 16 mm was obtained.

(Comparative example 1) Among the single plates laminated as the surface layer material, the fiber direction of the core-side single plate 1b is orthogonal to the wood chip orientation direction of the core material, and the fiber direction of the front-side single plate 1a is the wood of the core material. A composite plate having a thickness of 16 mm was obtained in the same manner as in Example except that the layers were laminated substantially parallel to the orientation direction of the slabs.

(Comparative Example 2) Four 2.2 mm thick Apiton veneers and 3 2.4 mm thick Apiton veneers are alternately laminated so that the fiber directions are perpendicular to each other, and a phenol resin adhesive is used. Bonding gave a 16mm thick plywood.

(Comparative test) Four test pieces each having a size of 50 × 450 mm were collected from each test body so that the fiber direction of the surface was the length direction of the test piece. Next, the test piece was supported at both ends by a span of 384 mm, and a bending fracture load was measured by applying a load to the center. The bending strength was calculated from the average value of the bending fracture load and the shape of the specimen, and the bending Young's modulus was calculated from the load and strain amount at that time. The comparative test results are shown in Table 1.

  As shown in the table, in the examples of the present invention, the bending strength in the length direction was larger and the bending Young's modulus was larger than in the comparative example.

  As described above, the composite material for a truck floor according to the present invention is not only excellent in economic efficiency and resource saving, but also has improved bending strength as compared with the prior art. As a result, the weight of the truck bed can be reduced.

  When used as a floor for trucks, if necessary, the surface of the composite board of the present invention is coated or coated with a resin plate or a metal plate to further improve performance such as wear resistance and water resistance. It is also possible to improve.

It is a partially cutaway perspective view showing an embodiment of the present invention. It is a perspective view which shows the example of application of this invention.
