The honeycomb panel 6 includes a honeycomb core 9 which is a core material made of a planar aggregate of hollow columnar cells 8 partitioned and formed by cell walls 7, as shown in each drawing including (4) of FIG. A surface plate 5 is joined to both opening end faces.

[0009] These will be described in more detail. First, as shown in FIG. 5, the honeycomb core 9 as a core material is composed of a planar aggregate of a large number of hollow columnar cells 8 partitioned into independent spaces by the cell walls 7. Cell wall 7 and cell 8
The cross-sectional shape of is typically a regular hexagonal shape as shown in the figure, but trapezoidal, triangular, quadrangular, and other various shapes are also possible. As the base material of the cell wall 7, that is, the honeycomb core 9, aluminum foil or other metal foil, fiber reinforced plastic sheet (FRP sheet), kraft paper or aramid paper or other special paper, vinyl chloride sheet or other plastic sheet, or other Various metals and non-metals such as organic and inorganic composite materials are used. Honeycomb core 9
Is known to have excellent weight-specific strength, light weight, high rigidity and strength, and excellent flatness accuracy, heat retention, heat insulation, sound insulation, and the like. The surface plate 5, which is a skin material, is bonded to both open end faces of the honeycomb core 9 by heating and pressing using a bonding material such as an adhesive or a brazing material. The material of the surface plate 5 is as described above. According to the honeycomb core 9, various metals and non-metals are appropriately selected and used. The honeycomb panel 6 is widely used as a structural material including wall materials, floor materials, and other building materials for various purposes based on the various characteristics of the honeycomb core 9 described above. Such a honeycomb panel 6 is shown in FIG.
Is shown as a wall material of a box, and 10 is an edge material in the figure.

By the way, the honeycomb core 9 which is the core material of the honeycomb panel 6 is manufactured by the following spreading method or corrugating method. In the spreading method, first, a bonding material such as an adhesive is applied to the base material in the form of a strip, and the applied bonding materials are stacked on top of each other with a half pitch offset, and then bonded by heat and pressure. Then, the honeycomb core 9 is obtained by pulling in the stacking direction. In the illustrated example, the honeycomb core 9 manufactured by such a spreading method is used, and the direction in which the base materials are bonded, that is, the cell walls 7 are bonded, that is, the bonding direction is the direction in which the bonding surface exists, the ribbon Called direction L,
The stacking direction and the spreading direction W are orthogonal to the ribbon direction L. On the other hand, in the corrugated method, the base material is first bent into corrugated plates, and a plurality of corrugated plates are displaced from each other by half a pitch of the corrugations, and the valleys and tops of the corrugated plates are joined with a bonding material such as an adhesive. The honeycomb core 9 is obtained by stacking in a block shape while interposing, and then applying heat and pressure to bond them together. In the honeycomb core 9 manufactured by the corrugation method as described above, the ribbon direction L described in the case of the expansion method described above corresponds to the direction in which the bonding surface between the cell walls 7 exists, that is, the bonding direction. W corresponds to the stacking direction. The honeycomb core 9 and the honeycomb panel 6 are generally configured as described above.

In the present invention, the honeycomb panel 6 as described above is as follows. That is, the honeycomb panel 6 of the present invention has an overall shape of a flat plate such as a square, a rectangle or the like, and has a positional relationship in which the joining direction such as the ribbon direction L of the honeycomb core 9 is inclined with respect to one side B thereof. ing.

These will be described in more detail. The honeycomb panel 6 has a honeycomb core 9 as a core material, and the surface plate 5 is joined to the opening end face of the honeycomb core plate 6 to form a flat plate shape (normally, the surface plates 5 are joined to both opening end faces of the honeycomb core 9, respectively). However, a type in which the surface plate 5 is joined only to one of the opening end faces is also possible. The whole shape is typically an isometric quadrangle such as a square or a rectangle as shown in the figure, but a quadrangle such as a rhombus, a trapezoid or a parallelogram,
Other polygonal shapes are possible. Honeycomb panel 6
The honeycomb core 9 is formed in such a shape by being surrounded by the side B which is an outline. Then, in this honeycomb panel 6, for example, FIG. 1 (1) diagram, (2) diagram,
(3) As shown in the figure, the honeycomb core 9 as a core material is bonded to one side B of the honeycomb core 9 in a positional relationship in which the joining direction between the cell walls 7 such as the ribbon direction L has an inclination angle α. It will be arranged. This inclination angle α is, for example, about 30 degrees in both positive and negative directions,
It is set to 45 degrees, 60 degrees, etc.

Various aspects of such a honeycomb panel 6 will be described. First, in the first example shown in FIG. 2 (1), first, three honeycomb cores 9 obtained by cutting a standard size are prepared, and each honeycomb core 9 is shown by a solid line in the drawing. So that the ribbon direction L with respect to each horizontal line
Are arranged side by side with the inclination angle α. Then, after overlaying the surface plates 5 indicated by broken lines in the drawing prepared according to the desired shape and size of the honeycomb panel 6 and bonding the respective honeycomb cores 9 with each other, the shape of the surface plate 5 is formed. -The honeycomb panel 6 is plate-cut as shown by the broken line in the figure by cutting the honeycomb core 9 along the dimension
Is obtained. That is, the honeycomb panel 6 is manufactured in which the entire shape is a rectangular flat plate shape, and the ribbon direction L of the honeycomb core 9 is inclined with respect to one side B thereof at the inclination angle α. The inclination angle α is specifically set for each so that the ribbon direction L coincides with the load acting direction P when used as a subsequent product. Further, the honeycomb cores 9 may be left in contact with each other, but may be further bonded by adhesion or the like.

Next, in the second example shown in FIG. 2 (2), first, a panel-like member in which the surface plate 5 is bonded to the honeycomb core 9 is prepared (up to this point, FIG. (This is the same as the honeycomb panel 1 of the conventional example of this kind). Then, as shown by the broken line in the figure, the panel-like thing shown by the solid line in this figure is cut so that the ribbon direction L of the honeycomb core 9 is inclined at an inclination angle α with respect to one side B. By
A honeycomb panel 6 having a planed surface is obtained. That is, by a method different from the method shown in FIG. 2 (1), the overall shape is a rectangular flat plate, and the ribbon direction L of the honeycomb core 9 is at an inclination angle α with respect to one side B thereof. The tilted honeycomb panel 6 is manufactured.

Next, in the third example shown in FIG. 2C, the overall shape is a rectangular flat plate shape, and the ribbon direction L of the honeycomb core 9 is different from the side B thereof.
A honeycomb panel 6 is shown tilted at a seed tilt angle α. That is, the honeycomb cores 9 that are inclined with respect to one side B at inclination angles α in both the positive and negative directions are collectively used. In such a honeycomb panel 6, according to the method shown in FIG. 2 (1), the honeycomb cores 9 are arranged side by side in an inclined state, and then a common surface plate 5 is joined and cut. Alternatively, it is manufactured by a method of joining the two prepared honeycomb panels 6 according to the method of FIG. 2 (2) described above.

Further, in the fourth example shown in FIG. 3A, the honeycomb panel 6 according to the present invention and the general honeycomb panel 1 of the conventional example of the type described above (see also FIG. 4). ) And are integrally mixed together. That is, the honeycomb panel 6 according to the present invention is arranged in the center, the general honeycomb panel 1 is arranged around the honeycomb panel 6, and an assembly in which these are integrated is shown. Then, the assembly shown in FIG. 3 (1) is also manufactured according to the above description while using the common surface plate 5.
Further, in a fifth example shown in FIG. 3 (2), an aggregate in which the honeycomb panel 6 according to the present invention and the general honeycomb panel 1 of the conventional example of the kind described above are mixed and integrated with each other. It is shown. That is, the overall shape is a square flat plate shape, and the four square honeycomb panels 6 and the plurality of rectangular honeycomb panels 1 are combined so that the honeycomb panels 1 are located on the three side surfaces of each honeycomb panel 6. It is used as a combination of these and is shown as an integrated one. The assembly shown in FIG. 3B is also manufactured by using the common surface plate 5 according to the above description. The fifth example shown in FIG. 3B is often used when the overall size and size are large.

The present invention is configured as described above. Then it becomes as follows. This honeycomb panel 6
In this way, in the honeycomb core 9 as the core material, the joining direction between the cell walls 7 such as the ribbon direction L, which is the direction having the highest rigidity and strength, is inclined at the inclination angle α with respect to the side B. . That is, in use as a product, the ribbon direction L and the like are inclined so as to correspond to the load acting direction P due to the acting direction of the external force and the position of the fulcrum. Therefore, the honeycomb panel 6 has excellent rigidity and strength against external force.

That is, for example, in the use example shown in FIG. 1 (5), such a honeycomb panel 6 is used as a wall material for a box. In this box, an external force is often applied obliquely from above as shown in the drawing in use, but in the main load acting direction P, the ribbon direction L of the honeycomb core 9 as the core material is used. Therefore, sufficient stress is generated in the honeycomb core 9 at this time, and thus the honeycomb panel 6 and the box are excellent in rigidity and strength. Further, FIG.
In the example shown in FIG. 3 (3), external forces are applied from diagonally upper left and right in the drawing, but both load acting directions P and ribbon directions L of both honeycomb cores 9 coincide with each other. Therefore, the honeycomb panel 6 has rigidity and strength corresponding to such an external force situation. FIG.
In the examples shown in (1) and (2), the external force from each diagonal direction is the main load acting direction P, and this is handled by each honeycomb panel 6, and the horizontal direction in the drawing. Since each honeycomb panel 1 responds to a relatively small external force in the vertical or vertical direction, rigidity and strength corresponding to the external force situation are provided.

[0019]

As described above, the honeycomb panel according to the present invention has a positional relationship in which the joining direction such as the ribbon direction of the honeycomb core, which is the core material, is inclined with respect to one side so as to match the load acting direction. By doing so, the following effects are exhibited.

First, the rigidity and strength are improved. That is, in this honeycomb panel, the rigidity and rigidity can be improved by tilting the joining direction such as the ribbon direction of the honeycomb core, which is the core material, so as to correspond to the load acting direction due to the external force at the time of use and to coincide with this. It has excellent strength and prevents twisting, bending, deformation and breakage.

Second, and yet this is easily accomplished. That is, in this honeycomb panel, the above-mentioned first point is easily realized by a simple configuration in which the positional relationship of the honeycomb core, which is the core material, is inclined. As described above, the effects exhibited by the present invention are remarkable and large, for example, all the problems existing in this type of conventional example are solved.
