FIG. 5 is a perspective view of the reinforcing material.
As shown in FIG. 1 or FIG. 2, the particle board 1 includes a reinforcing layer 2 and two wood fiber layers 3 sandwiching the reinforcing layer 2 and is formed in a three-layer structure.

The reinforcing layer 2 includes a reinforcing material 4, a woody large chip 5, and a binder (not shown).
The reinforcing material 4 is formed by processing a plate material 7 formed of a plastically deformable material, and the processing method will be described below. Here, the plastically deformable material may be a polymer material such as plastic, PET fiber, polyester fiber, and aramid fiber, glass fiber, paper, metal, etc., especially from the ease of processing, price and strength. It is preferable to use a polymer material such as plastic or aluminum.

First, as shown in FIG. 3, in the plate material 7, a plurality of rows of intermittent cuts 8 including a plurality of cuts 10 provided at a predetermined interval b are formed at a predetermined interval c.
In this case, each cut portion 10 is linearly formed with a predetermined length a so as to penetrate the front and back surfaces of the plate material 7. In this embodiment, the discontinuous cut 8 extends in a straight line by arranging the cut 10 on a straight line. Note that the disposition of the cut portion 10 can be changed as appropriate, for example, by disposing it slightly off the straight line.

  Here, in this embodiment, each cut portion 10 is formed by a cutting hole as shown in FIG. 4A, but as shown in FIG. You may form as a hole. Moreover, in each cut | interruption part 10, as shown in FIG.4 (c), you may form and provide the substantially circular opening 9 in the both ends of the cut | interruption part 10, and the edge of the cut | interruption part 10 is obtained by this structure. It is possible to prevent the portion from being torn and to reduce the amount of waste material as compared to the case where the cut portion 10 is formed as a punched hole shown in FIG. Moreover, in each cut | interruption part 10, as shown in FIG.4 (d), you may form by providing the arc-shaped cut | interruption 12 in the both ends of the cut | interruption part 10, and also by this structure, the edge part of the cut | interruption part 10 is provided. It is possible to prevent tearing and to further reduce the amount of waste material as compared with the case where the cut portion 10 is formed as a punched hole shown in FIG. Furthermore, the cut portion 10 formed in a straight line may be formed so as to be linear as a whole by cutting the plate 7 into a fine corrugation.

Further, the predetermined length a and the predetermined interval b of the cut portion 10 in each intermittent cut 8 and the predetermined interval c of the intermittent cut 8 can be set as appropriate. Moreover, in the intermittent break part 8, you may set the predetermined length a for every break part 10 to a different value.
And the intermittent break 8 is formed so that the cut | interruption part 10 may be arrange | positioned in zigzag form in the board | plate material 7, and all the intermittent breaks 8 are formed in parallel in this embodiment. Note that the intermittent cuts 8 do not necessarily have to be formed in parallel, and can be appropriately changed such as being formed with a slight inclination.

  Next, the plate material 7 provided with a plurality of intermittent cuts 8 is stretched in a direction (left and right direction in FIG. 3) orthogonal to the direction in which the intermittent cuts 8 extend (vertical direction in FIG. 3), and the plate material 7 is plastically deformed. Let Here, the extending direction of the intermittent cuts 8 refers to the direction in which the straight lines extend when both ends of all the cuts 10 constituting the intermittent cuts 8 are in a straight line, and constitutes the intermittent cuts 8. When the both ends of the cut part 10 to be performed are not on a straight line, it refers to the extending direction of the approximate line with respect to both ends of all the cut parts 10 in each intermittent cut 8. Further, the orthogonal directions include directions in the range of about 10 ° from the direction of 90 ° to the vertical direction with respect to the direction in which the intermittent cut 8 extends.

In this case, since the cut portions 10 are continuously provided in a staggered pattern in the plate material 7, the plate material 7 is three-dimensionally deformed in the x direction, the y direction, and the z direction (see FIG. 1). .
Here, as shown in FIG. 5, the band-like portion 11 sandwiched between the two adjacent cut portions 10 in the intermittent cuts 8 rises in the z direction in proportion to the force for stretching the plate material 7. Will go. That is, by stretching the plate material 7, the belt-like portion 11 is three-dimensionally deformed so as to increase the total dimension of the plate material 7 in the plate thickness direction.

Note that the force for stretching the plate member 7 can be set as appropriate, and by increasing or decreasing the force, it is possible to adjust the amount of rising of the belt-like portion 11 in the z direction. It becomes possible to adjust the total dimension of the.
And the reinforcing material 4 is provided with the strip | belt-shaped part 11 which deform | transformed three-dimensionally over substantially the whole surface by forming the cut | interruption part 10 uniformly in the board | plate material 7. FIG.
Here, the reinforcing material 4 can be simulated from the pseudo rhombus net shape by adjusting the predetermined length a and the predetermined interval b of the cut portion 10 in the plate 7, the predetermined interval c of the intermittent cut 8, and the force for stretching the plate 7. It is possible to form a three-dimensional shape having various directions and three-dimensionality up to the honeycomb shape.

  The reinforcing material 4 is formed by subjecting the plate material 7 to the above processing. And in this reinforcing material 4, since the strip | belt-shaped part 11 stands | starts up toward the z direction of the board | plate material 7, the total dimension of the thickness direction of the reinforcing material 4 is large with respect to the board thickness of the board | plate material 7 before making it plastically deform. Become. Thereby, the board | plate material 7 will deform | transform so that it may have a surface extended in the synthetic | combination direction of an x direction, a y direction, and az direction. Therefore, according to the reinforcing material 4, even when the plate thickness is formed thin, all of the plate width direction (x direction), the vertical direction (y direction) and the plate thickness direction (z direction) of the particle board 1 are 3 It becomes possible to reinforce strongly in dimension.

The large wooden chip 5 is formed by crushing natural plant raw materials such as wood and bamboo. The binder is preferably a thermosetting adhesive such as a urea resin adhesive, a phenol resin adhesive, a melamine resin adhesive, or a urethane resin adhesive from the viewpoint of workability and cost. .
The wood fiber layer 3 is formed by mixing and forming a wood-based small chip 6 and a binder. Here, it is preferable that the wood-based small chip 6 used for the wood fiber layer 3 is finer than the wood-based large chip 5 used for the reinforcing layer 2. Note that the binder used for the wood fiber layer 3 may be the same as the binder used for the reinforcing layer 2.
In the particle board 1, first, wood chips 5 and 6 are manufactured by crushing wood waste materials or the like with a commercially available crusher or the like. In this case, the crushed wood chips 5 and 6 are sieved, fine wood pieces are used as wood wood small chips 6 for the wood fiber layer 3, and relatively large wood pieces are wood wood large for the reinforcing layer 2. Used as chip 5.

  Next, a necessary amount of a mixture obtained by mixing the wood-based small chip 6 for the wood fiber layer 3 and the binder is put into the pressure vessel, and the wood fiber layer 3 is formed by applying a predetermined pressure. Similarly, a necessary amount of a mixture of the wood-based large chip 5 for the reinforcing layer 2 and the binder is added to the upper layer of the wooden fiber layer 3 in the pressure vessel, and a predetermined pressure is applied to the reinforcing layer. Forming 2 is performed. Further, by forming the wood fiber layer 3 on the upper layer of the reinforcing layer 2, the particle board 1 is formed in three layers. When forming each layer, the pressure is applied to the pressure vessel for a predetermined time so that the wood chips 5 and 6 are uniformly impregnated with the binder, and the wood chips 5 and 6 are impregnated with the binder. The amount is adjusted by adjusting the pressurization time and pressure.

  Here, at the time of forming the reinforcing layer 2, the reinforcing material 4 is interposed at a substantially central portion in the thickness direction of the reinforcing layer 2, and the mixture of the woody large chip 5 and the binder is formed on the surface of the reinforcing material 4. It is formed by spraying and fusion bonding. In this case, in the reinforcing material 4, the band-like portions 11 protrude from the front and back surfaces of the plate material 7, and each cut portion 10 opens three-dimensionally in the plate width direction, the vertical direction, and the plate thickness direction of the plate material 7. Therefore, the mixture of the wood-based large chip 5 and the binder is easily adapted to the cut portion 10 and the strength of the reinforcing material 4 can be further increased.

And each layer formed in this way is hot-pressed in a state where it is laminated in a predetermined pressurizing region in the press machine, whereby the particle board 1 formed into a substantially square plate shape is obtained.
According to the particle board 1, the reinforcing material 4 reinforces the particle board 1 three-dimensionally strongly in the x direction, the y direction, and the z direction, thereby increasing the strength even when the particle board 1 is formed thin. Is possible. In addition, even when vibration is applied to the particle board 1 by inserting the reinforcing material 4 formed of a material having a density different from that of the wood-based large chip 5 and the mixture of the binder, the wood-based large chip 5 and the mixture of the binder and the reinforcing material 4 have different frequencies, so that transmission of vibration can be suppressed, and the sound insulation effect of the particle board 1 can be improved.

Next, a particle board according to a second embodiment of the present invention will be described with reference to the drawings.
FIG. 6 is a plan view showing the arrangement of cut lines in the reinforcing material plate provided in the particle board according to the second embodiment of the present invention.
Since the basic configuration of the particle board (not shown) according to the second embodiment of the present invention is the same as that of the particle board 1, the same components are denoted by the same reference numerals and description thereof is omitted.

The particle board according to the second embodiment of the present invention includes a reinforcing material 13 instead of the reinforcing material 4 in the particle board 1.
The reinforcing material 13 is formed by processing the plate material 7 in the same manner as the reinforcing material 4, and the processing method will be described below.
First, in the plate member 7, as shown in FIG. 6, a plurality of rows of intermittent cuts 15 formed of a plurality of cut portions 14 provided at a predetermined interval f are formed at a predetermined interval g.

  In this case, each cut portion 14 is formed in a square shape so as to penetrate the front and back surfaces of the plate member 7, and an inner angle is set to a predetermined angle d and a distance between both ends is set to a predetermined length e. And in this embodiment, the both ends of all the cut | interruption parts 14 are arrange | positioned on the straight line in each intermittent cut 15, and let the extending direction of this straight line be the direction where the intermittent cut 15 is extended. . In addition, the arrangement of the cut portions 14 in each intermittent cut 15 can be changed as appropriate, for example, by arranging both ends of each cut portion 14 slightly shifted from a straight line. In this case, all the cut portions 14 in each intermittent cut 15 are arranged. The direction in which the approximate line (straight line) extends from both ends is defined as the direction in which the intermittent break 15 extends. Here, in the present embodiment, each cut portion 14 is formed by a cut hole. However, similarly to the cut portion 10, it may be formed as a punched hole having a certain area, or the cut portion 14. A substantially circular opening may be formed at both ends.

Moreover, the predetermined interval f of each cut part 14 in each intermittent cut 15, the predetermined angle d of the internal angle of each cut part 14, the predetermined length e between both ends, and the predetermined gap g of the intermittent cut 8 can be set suitably. Moreover, in the intermittent cut part 15, you may set the predetermined angle d of an internal angle for every cut part 14, and the predetermined length e between both ends to a different value.

In this case, since the cut portions 14 are continuously provided in a staggered pattern in the plate material 7, the plate material 7 is three-dimensionally deformed in the x direction, the y direction, and the z direction.

  Here, the belt-like portion 16 sandwiched between the two cut portions 14 adjacent to each other in the intermittent cut 15 in the vertical direction rises in the z direction in proportion to the force for stretching the plate material 7. That is, by stretching the plate material 7, the belt-like portion 16 is three-dimensionally deformed so as to increase the total dimension of the plate material 7 in the plate thickness direction. In this case, since each cut portion 14 is formed in a square shape, each band-like portion 16 has a convex portion 17, and even when the amount of the plate material 7 stretched by the convex portion 17 is small, the plate material 7 can be formed with a large total dimension in the thickness direction.

  The reinforcing material 13 is formed by subjecting the plate material 7 to the above processing. And in this reinforcing material 13, since the strip | belt-shaped part 16 stands | starts up toward the z direction of the board | plate material 7, the total dimension of the board | plate thickness direction of the reinforcing material 13 is large with respect to the board thickness of the board | plate material 7 before making plastic deformation. Become. Thereby, the board | plate material 7 will deform | transform so that it may have a surface extended in the synthetic | combination direction of an x direction, a y direction, and az direction. Therefore, according to the reinforcing material 13, even when the plate thickness is thin, all of the plate width direction (x direction), vertical direction (y direction) and plate thickness direction (z direction) of the particle board are three-dimensional.
