Description

  The present invention relates to a panel used as a wall material or a component of a building, furniture, automobile, aircraft, and the method for producing the panel, and more particularly, to a lightweight and highly rigid panel represented by a honeycomb core panel and the panel. It relates to the creation method.

  2. Description of the Related Art Conventionally, a panel having a high rigidity and a light weight has been developed as a wall material or a structural member of a building, an automobile, an aircraft, or the like. As such a highly rigid and lightweight panel, a honeycomb core panel is conventionally known. 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 cylinder to the flat plate. Yes. However, there are theoretically no joints (glue allowances) on the upright hexagonal edges, and in reality, the hexagonal cylinders are joined with a glue margin equivalent to the thickness of the hexagonal cylinder. Joining over the entire surface is very difficult and costly. In particular, the honeycomb core is weak against the impact (shearing force) from the side only when the hexagonal cylinder stands upright in a space-filled state, and the bending rigidity does not appear unless a flat plate is joined from above and below to form a panel shape. For this reason, in the honeycomb core panel, it is particularly important to join the hexagonal cylinder and the flat plate. If the joining is not performed firmly, the strength becomes insufficient, and there is a problem that the honeycomb core panel cannot be used as a panel.

In addition to the honeycomb core panel, the following conventional techniques (J01) to (J05) are conventionally known as techniques relating to lightweight and highly rigid panels.
(J01) Technology described in Patent Document 1 (Japanese Patent Publication No. 47-47514) In Patent Document 1, panel pieces formed by joining (joining) a large number of quadrangular pyramids at the bottom four sides are opposed to each other. Bonded panels are described.
(J02) Technology described in Patent Document 2 (Japanese Patent Laid-Open No. 3-93513) In Patent Document 2, panel pieces having triangular pyramid-shaped protrusions formed at the tip of a hexagonal cylinder are joined to each other. Panel is described.

(J03) Technology described in Patent Document 3 (U.S. Pat. No. 2,481,046) Patent Document 3 describes a pyramid-shaped panel in which triangular or truncated pyramids having a flat tip are periodically arranged. A panel is described in which flat plates are opposed from both sides and joined to the flat plate at a flat tip portion of the frustum and a flat portion surrounded by the frustum.
(J04) Techniques described in Patent Document 4 (Japanese Patent Laid-Open No. 3-125744) and Patent Document 5 (US Pat. No. 2,986,241) Patent Documents 4 and 5 include a triangular main body and three sides of a triangle. A panel-like member is described in which a large number of triangular pyramids are combined by combining a large number of conical wall forming pieces having joint portions formed by bending.
(J05) Technology described in Patent Document 6 (Japanese Patent Application Laid-Open No. 2004-100326) Patent Document 6 is formed by joining a solid truss composed only of a ridge line portion of a quadrangular pyramid and a flat plate facing the solid truss. A panel-like structure that can be used as a molded form is described. Patent Document 6 describes that a reinforcing member (11) is provided in order to increase rigidity.

Japanese Examined Patent Publication No. 47-47514 (right column, page 1, lines 5 to 37, FIG. 1) Japanese Patent Laid-Open No. 3-93513 (FIGS. 1, 2, 4, 29) US Pat. No. 2,481,046 (FIGS. 1 to 11) Japanese Patent Laid-Open No. 3-125744 (FIGS. 1 and 2) U.S. Pat. No. 2,986,241 (FIGS. 14-16) JP 2004-100326 A

In the prior art (J02), since the outer end portion is a hexagonal cylinder and has a honeycomb shape, there is a problem that it takes time and effort to join a flat plate for use as a honeycomb core panel.
In the prior art (J03), a pyramid forming panel (corrugated panel) in which a triangular frustum and a quadrangular frustum are periodically formed is used as a core, and flat plates are joined from both sides. Since a body is required, there is a problem that the cost is increased.

In the prior art (J04), since a panel in which a large number of triangular pyramids are combined by combining triangular plates is manufactured, there is a problem that manufacturing effort, time, and cost are enormous.
In the prior art (J05), since a three-dimensional truss composed only of a ridge line portion of a quadrangular pyramid is used, there is a concern about rigidity, and it is expensive to provide a reinforcing member (11) to increase rigidity. There is a problem of becoming.
