Panel, panel piece, and panel creation method

Technical field

TECHNICAL FIELD [0001] The present invention relates to a panel used as a structural member of a building, furniture, automobile, aircraft, a panel piece capable of producing the panel, and a method for producing the panel, and more particularly, a hard cam. The present invention relates to a lightweight and highly rigid panel represented by a core panel, a panel piece, and a method for producing the panel.

Background art

[0002] Hitherto, high-rigidity and light-weight panels have been developed as building materials for automobiles, aircraft, and other wall materials. A hard core panel has been conventionally known as such a highly rigid and lightweight panel. A honeycomb core panel is formed by placing a regular hexagonal cylinder upright between a pair of flat plates in a space-filled state (a state where there is no gap in the space), and joining the edges of the hexagonal tube to the flat plate. ing. However, there is theoretically no joint (gluing allowance) on the upright hexagonal edge, so in reality, the hexagonal cylinder is joined with a gluing margin equivalent to the thickness of the hexagonal cylinder. It is very difficult to join all over the surface, and the cost is increasing. In particular, if the hexagonal cylinder is just upright in a space-filled state, the Hercam core will not have bending rigidity unless it is constructed in the form of a panel by joining flat plates from the top and bottom that are vulnerable to side impact (shearing force). For this reason, in the case of a hard cam core panel, the connection between the hexagonal cylinder and the flat plate is particularly important. If the connection is not performed firmly, the strength is insufficient, and there is a problem that the panel is not used as a panel.

[0003] In addition to the above-mentioned hard cam core panel, the following conventional techniques CF01) to CF06) are conventionally known as techniques relating to lightweight and highly rigid panels.

Disclosure of the invention Problems to be solved by the invention

[0007] In the prior art CF01), since a large number of quadrangular pyramids are concatenated on the four sides at the bottom, it takes a lot of time and labor to manufacture the panel and the manufacturing cost is high. There's a problem.

In the prior art CF02), since the outer end portion is a hexagonal cylinder and has a her cam shape, there is a problem that it takes time and effort to join a flat plate for use as a hard core panel.

In the prior art CF03), a pyramid forming panel (corrugated panel) in which a triangular frustum and a quadrangular pyramid are periodically formed is used as a core, and both side forces are joined to each other. Therefore, there is a problem that the cost becomes high.

[0008] The conventional technique CF04) has a problem that the labor, time, and cost of manufacturing are enormous because a panel in which a large number of triangular pyramids are combined by combining triangular plates is manufactured.

The prior art CF05) uses a solid truss composed only of ridges of a quadrangular pyramid, so there is anxiety about rigidity, and it is costly to provide a reinforcing member (11) to increase rigidity. There is a problem of becoming high.

In the prior art CF06), since the point of the convex portion is sharp, the contact portion with the other panel piece becomes a point and does not come into contact with the surface, so that there is a problem that adhesion is difficult. In addition, when a force is applied to the manufactured panel, stress concentrates on the sharp tip, which may cause peeling of the joint or buckling of the tip at low load. Further, when plastic processing is performed with the sharp tip sharpened, there is a problem in that it is theoretically difficult to manufacture by plastic processing because the strain is infinite and breaks at the tip.

[0009] In view of the above circumstances, the present invention has the following description (O01) as a technical problem.

BEST MODE FOR CARRYING OUT THE INVENTION

Next, specific examples (examples) of the embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to the following examples.

Example 1

FIG. 1 is an explanatory diagram of a panel according to Embodiment 1 of the present invention, and FIG. 1A is a pair of panel pieces facing each other. 1B is a perspective explanatory view of the panel with the panel piece fitted, FIG. 1C is a cross-sectional view of the main part of FIGS. 1A and 1B, and FIG. 1D is the position of the fitting convex portion of the panel It is explanatory drawing of a relationship.

In FIG. 1, the panel 1 of the first embodiment of the present invention has a pair of upper and lower panel pieces 2, 2 ′. The lower panel piece 2 includes a flat surface portion 3 and a quadrangular prism-shaped (polygonal) fitting convex portion 4 formed by being recessed upward and convex with respect to the flat surface portion 3. Each of the fitting protrusions 4 is formed in the same quadrangular prism shape, and has four rectangular wall surfaces 4a and a rectangular top surface 4b at the tip of the wall surface 4a. The fitting convex portions 4 are arranged adjacent to the periphery of the flat portion 3, and the fitting convex portions 4 are periodically arranged with the flat portion 3 interposed therebetween. Therefore, the fitting recess 6 is formed by a square columnar space surrounded by the wall surface 4 a of the fitting protrusion 4 and the flat surface 3.

In Example 1, the flat plate 3 as a non-covered portion and the fitting convex portion 4 as a processed portion are formed by pressing the flat plate.

The upper panel piece 2 ′ is also configured in the same manner as the lower panel piece 2, and has a flat surface portion 3 ′, a fitting convex portion 4 ′, a fitting concave portion, and the like.

(Operation of Example 1)

One panel 1 of the embodiment having the above-described configuration is created by fitting one fitting convex part 4, 4 'of the upper and lower pair of panel pieces 2, 2' into the other fitting concave part 6, 6 '. Is done. At this time, as shown in FIGS. 1C and 1D, the top surfaces 4b and 41 / of the fitting convex portions 4 and 4 ′ are in close contact with the flat surface portions (bottom surfaces) 3 and 3 ′ of the fitting concave portions 6 and 6 ′. The upper and lower wall surfaces 4a and 4a 'come into contact with each other in close contact (surface contact). Therefore, the upper and lower panel pieces 2 and 2 'are constrained to each other by surface contact, so that they are deformed even when an external force is applied. In other words, the rigidity can be increased.

Therefore, the panel 1 of Example 1 created by fitting the fitting convex portions 4, 4 ′ and the fitting concave portions 6, can increase the rigidity. In particular, in the panel 1 of Example 1, since the panel pieces 2 and 2 'have the flat portions 3 and 3', the panel pieces 2 and 2 'can be used as a panel having high rigidity without applying a flat plate from the back side of the panel pieces 2 and 2'. . In addition, panel 1 of Example 1 is made by fitting panel pieces 2 and 2 ′ made by plastic processing of a single plate, so it is light. Can be quantified.

[0039] Furthermore, in the panel 1 of the first embodiment, the fitting protrusions 4, 4 'and the fitting recess 6 are arranged in a predetermined pattern by plastically deforming one plate body with a press carriage. Panel pieces 2 and 2 'can be obtained, so that panel pieces 2 and 2' can be obtained easily and at low cost.

Further, in the panel 1 of Example 1, the panel pieces 2 and 2 ′ are flexible before being fitted, and can be wound up into a cylindrical shape. Therefore, the panel pieces 2, 2 'can be easily transported and transported to the destination, and a pair of panel pieces 2, 2' can be fitted at the destination to produce a tough, high-rigidity panel 1. it can. As a result, the panel 1 of the first embodiment can be transported in a compact manner and a highly rigid structure can be created at the destination, so that it can also be used for the construction of a space structure. Also, the user purchases the wound long panel pieces 2, 2 'and cuts and uses the long panel pieces 2, 2' for the required length at the place of use. Is also possible.

[0040] Further, in the panel 1 of Example 1, since the fitting convex portions 4, 4 'and the fitting concave portion 6, are fitted in close contact with each other, the frictional force of the contact portion as a whole becomes very large, Ideally, it can be used in a mated state without using adhesive. Therefore, the work of combining the panel pieces 2 and 2 'is simplified and the work efficiency is improved. In addition, since it is not necessary to use an adhesive, the panel pieces 2 and 2 'can be separated and disassembled after use, and after disassembly, they can be wound up and cleaned as described above. Furthermore, the disassembled panel pieces 2, 2 'can be re-fitted and used repeatedly. As a result, cost can be reduced and garbage can be reduced.

In the panel 1 of the first embodiment, the panel pieces 2 and 2 ′ can be fixed to each other using an adhesive. Further, in the panel 1 of Example 1, the height of the fitting convex portion 4, that is, the distance from the flat portion 3 of the top wall 4b can be arbitrarily changed.

Example 2

FIG. 2 is an explanatory diagram of the panel of Example 2, FIG. 2A is an explanatory diagram of the lower panel piece with the panel pieces spaced apart, FIG. 2B is a plan view of FIG. 2A, and FIG. FIG. 2 is an explanatory diagram of a positional relationship of fitting convex portions corresponding to FIG. In the description of the second embodiment, constituent elements corresponding to the constituent elements of the first embodiment are denoted by the same reference numerals in the last one digit, and detailed description thereof is omitted.

The second embodiment is different from the first embodiment in the following points, but is configured in the same manner as the first embodiment in other points.

In FIG. 2, in the panel piece 12 of Example 2, each fitting convex part 14 is formed in the shape where the fitting convex part 4 of Example 1 was chamfered. Therefore, the fitting convex portion 14 has a quadrangular wall surface 14a, a quadrangular chamfered portion 14c, and an octagonal top surface 14b formed at the tip of the wall surface 14a and the chamfered portion 14c. Therefore, the fitting convex part 14 of Example 2 is formed in an octagonal prism shape (polygonal prism shape). Since the upper panel piece W is the same as the lower panel piece 12, detailed description thereof is omitted.

[Operation of Example 2]

In the panel 11 of the second embodiment having the above-described configuration requirements, a chamfered portion 14 c is formed on the fitting convex portion 14. In the fitting convex part 4 of Example 1, the corner (corner) part of the base end part of the quadrangular prism coincides with the corner of the fitting convex part 4 arranged diagonally opposite in the plan view. Therefore, the fitting convex portion 4 of Example 1 has a very large distortion (deformation amount) at the corner portion during press working, and is difficult to process. However, since the fitting convex portion 14 of Example 2 is formed with the chamfered portion 14c, the corner does not coincide with the base end portion of the other fitting convex portion 4. Therefore, compared to the case of the first embodiment, the cleaning can be easily performed, and the processing cost and the cache time can be reduced.

In FIG. 14, in the panel piece 212 of Example 14, a plurality of polygonal pyramid-shaped fitting projections 213 formed by plastic molding of one flat plate are triangular pyramid-shaped fittings. It is configured in a hexagonal pyramid shape in which a band-like ridge line joint (wall surface) 213e is formed on the ridge line portion of the convex part. Therefore, the fitting convex portions 213 and 213 ′ have a trapezoidal cone wall (wall surface) 213a and the belt-shaped ridge line joint portion (wall surface) 213e, and the bottom surface of the polygonal pyramid shaped fitting convex portion 213 ( Hole bottom 213c is formed in a hexagonal shape close to a triangle. Then, a regular hexagonal flat plate-like joint portion (top surface) 213b is formed at the tip of the fitting convex portion 213.

In the panel piece 212, in accordance with the hexagonal pyramid-shaped fitting projection 213, the flat portion 214 surrounded by the fitting projection 213 is formed in the same hexagonal shape as the bottom surface 213c. In the panel piece 212 of the fourteenth embodiment, the joint portion (top surface) 213b is arranged at a location where two of the six bottom vertices 213d of the hexagonal bottom surface 213c are concentrated on the edge of the flat portion 214. The same hexagonal to-be-joined plane part (joined part) 216 is formed.

Therefore, the panel 211 of the fourteenth embodiment is formed by bonding the bonding portions 213b and 213b ′ forces of the pair of panel pieces 212 and 212 ′ to the bonded plane portions 216 and 21 respectively with an adhesive.

Therefore, the panel pieces 212 and 212 'can be obtained easily and at low cost.

Further, the panel of Example 14 is often used in buildings, and can form an octet truss structure that is structurally stable and has high rigidity. Therefore, since the panel 211 of Example 14 is supported by the surface (cone wall 213a) formed only by the frame portion such as the octet truss structure used in the building, the rigidity can be increased.

Further, the panel 211 of Example 14 is a combination of an approximate tetrahedron and an approximate octahedron, has pseudo-isotropic rigidity (has pseudo-isotropic properties), and has a pair of panel pieces 212, 2 By simply joining (bonding) 12 ', a panel having high rigidity against shearing force (force in the direction of shifting the upper and lower surfaces of panel 211 in the opposite direction) can be created. Further, in the panel 211 of the fourteenth embodiment, the panel pieces 212 and 212 ′ have flexibility before being joined (bonded), and can be wound up into a cylindrical shape. Therefore, the panel pieces 212 and 212 'can be easily transported and transported to the destination, and a pair of panel pieces 212 and 212' are joined at the destination to produce a tough and highly rigid panel 211. be able to. As a result, since the panel of Example 14 can be transported in a compact manner and a highly rigid structure can be created at the destination, it can be used for the construction of a space structure.

Furthermore, in the panel 211 of Example 14, the flat plate-like joint portion 213b and the joined plane portion 216 are compared with the panel (see the related art CF06) that joins the apex of the tip composed of dots and the ridge composed of the line. And ridge line joints (glue margins) 213e and 213e ' Therefore, it can be joined on the surface and plastic working is also reduced. As a result, the adhesive can be applied and the bonding operation can be performed easily.
