Description

  The present invention relates to a honeycomb structure that is used as a panel in a building, a vehicle, a road, or the like, or used as a core material of a panel, and in particular, a paper, a plastic, a metal plate or the like is bent to have a compressive strength. The present invention relates to an optimum honeycomb structure as an excellent panel.

  Honeycomb structures are used for various applications because they have excellent compressive strength. In particular, a paper honeycomb structure is light and has an excellent compressive strength. However, when the honeycomb structure becomes thick, there is a drawback that the honeycomb structure is easily deformed by a force in a direction parallel to the surface. For this reason, the honeycomb structure used for the core material of a thick panel needs to laminate | stack a thin honeycomb structure in a multilayer structure, and there exists a fault that a shape is complicated and manufacturing cost becomes high. In addition, since the honeycomb structure has a shape that opens on both sides, it is necessary to fix the surface plate in order to make the inside closed structure. That is, there is a drawback that it cannot be used as a panel in a state where the surface plate is not used.

  In order to eliminate such drawbacks, various panel structures have been developed. (See Patent Documents 1 to 4)

JP-A-2005-76766 JP 2006-116830 A Japanese Patent Laid-Open No. 3-93513 Japanese Patent Laid-Open No. 10-166481

  Patent Document 1 describes a three-dimensional truss structure surface plate assembly manufactured from paper or the like, and Patent Document 2 describes a paper structure. Since these structures do not open on both sides like the honeycomb structure, they can be used as a panel without fixing the surface plate. In addition, since it is supported by a triangular paper surface, the compressive strength can be increased. However, these structures cannot be supported in a line shape like the honeycomb structure in a state where the surface plate is fixed or supported by a plane, and the support becomes localized, and force is applied to the support part. There is a defect that tends to concentrate and deform easily.

  The structure of Patent Document 3 can support the surface plate and the plane to be supported in a line shape, but has a drawback that the structure is extremely complicated and the manufacturing cost is high. The structure of Patent Document 4 can be made relatively simple in shape, but has a drawback that the support is localized and the support force concentrates and is easily deformed.

  The present invention has been developed for the purpose of solving the above drawbacks. An important object of the present invention is to achieve a compressive strength that is not inferior to that of a honeycomb structure, and the supporting force does not rapidly decrease even when the pressure exceeds the limit of the compressive strength. An object of the present invention is to provide a honeycomb structure having excellent strength against a force acting in a thrust direction parallel to the surface.

  Another important object of the present invention is that the surface plate and the supporting plane can be supported in a line shape by the hexagonal opening edges constituting the honeycomb structure, and the surface plate is fixed on one side and closed inside. An object of the present invention is to provide a honeycomb structure capable of providing a space.

Means and effects for solving the problems

  The honeycomb structure of the present invention has honeycomb-shaped opening edges on both sides, and the hexagonal opening edges constituting the honeycomb shape have zigzag parallel edges 3 arranged in parallel to each other. A hexagonal honeycomb shape is formed by the parallel edges 3 and the chevron edges 4 as shapes connected by the chevron edges 4. Further, the honeycomb structure is connected with two inclined surfaces 1 extending inward from the parallel edges 3 and inclined downward toward the center inside the two parallel edges 3 facing each other. The opposite parallel edge 3 of the opening edge of the honeycomb shape in which the bottom line at the center of is opposite to the opposite surface is formed. Furthermore, the honeycomb structure is formed with a chevron edge 4 connected to the opposite parallel edge 3 by a boundary edge 2a of the tetracube 2 which is a tetrahedron formed by connecting the triangle 2X at the outer periphery, The other boundary edges 2b and 2c of the tetracube 2 are the boundary between the two inclined surfaces 1 and the tetracube 2 and the boundary between the adjacent tetracubes 2 and arranged in a plurality of rows along the chevron edge 4. doing.

  In addition to realizing a compressive strength superior to that of the conventional honeycomb structure, the above honeycomb structure does not have a sudden decrease in the bearing capacity against pressure exceeding the limit of the compressive strength. It is also characterized by excellent strength against forces acting in the thrust direction parallel to the surface. This is because the above honeycomb structure is not composed only of vertical walls with respect to compressive strength as in the prior art, but the honeycomb-shaped parallel edges are supported by two inclined surfaces, and the chevron edges are tetracubes made of triangular tetrahedrons. It is because it supports. The tetracube realizes extremely strong compressive strength, and the parallel edges arranged therebetween support the compressive force in a state where it can be elastically deformed by two inclined surfaces. For this reason, in addition to realizing an excellent compressive strength, there is a feature that an excellent compressive strength is not lost even in a deformed state. Furthermore, the compressive strength is not supported only by the vertical wall as in the prior art, but the compressive strength is supported by the two inclined surfaces and the tetracube, so that the strength against the force in the thrust direction can be remarkably improved. This is because both the tetracube and the two inclined surfaces can firmly support the thrust force.

  22 and 23 are graphs showing the results of strength tests of the honeycomb structure of the present invention and the conventional honeycomb structure. FIG. 22 shows the compressive strength in the thickness direction of the honeycomb structure, and FIG. 23 shows the strength of the honeycomb structure in the thrust direction. Here, in the measurement of strength, the honeycomb structure of the present invention used the structure shown in FIG. 1, and the conventional honeycomb structure used the structure shown in FIG. Furthermore, in the measurement of the compressive strength in the thickness direction, the diagonal line (one side of the cell) of the hexagonal opening edge constituting the honeycomb shape is set to 15 mm, and the height (thickness) is set to 16 mm. Each honeycomb structure was compressed from both sides, and the load against the displacement in the thickness direction was measured. Further, in the measurement of the strength against the force in the thrust direction, the diagonal line (one side of the cell) of the hexagonal opening edge constituting the honeycomb shape is set to 20 mm, and the height (thickness) is set to 21 mm. A plate with a plate area of 50 mm x 110 mm is bonded to both sides of each honeycomb structure (adhesive area is 50 mm x 75 mm), and a load in the reverse direction is applied to each plate to load against displacement in the thrust direction Was measured.

  The compressive strength in the thickness direction of the honeycomb structure is as shown in FIG. 22 in the honeycomb structure of the present invention (indicated by curve A) with a maximum load of 22.8 kN (displacement in the compression direction of 2.4 mm). In the conventional honeycomb structure (indicated by curve B), the maximum load was 13.7 kN (displacement in the compression direction: 2.5 mm). Further, the load at which the displacement in the compression direction becomes 5.0 mm was about 20 kN in the honeycomb structure of the present invention, whereas it was about 12 kN in the conventional honeycomb structure. As can be seen from FIG. 22, the honeycomb structure of the present invention exhibited an excellent compressive strength 1.5 times or more that of the conventional honeycomb structure. Further, as shown in FIG. 23, in the strength against the force in the thrust direction of the honeycomb structure, the load at which the displacement in the thrust direction becomes 5.0 mm is about 0. 0 for the conventional honeycomb structure (indicated by the curve D). Whereas it was 24 kN, the honeycomb structure of the present invention (shown by curve C) had a strength of about 0.37 kN, which was 1.5 times or more superior to the conventional honeycomb structure. As can be seen from the above results, it can be seen that the honeycomb structure of the present invention has a compressive strength superior to that of the conventional honeycomb structure and can significantly improve the strength against the force in the thrust direction.

  Since the strength in the thrust direction is excellent, the above honeycomb structure has a feature that it can be thickened by one piece. When the conventional honeycomb structure is made thick, the strength in the thrust direction is particularly lowered. Therefore, what is required to have a thickness needs to have a complicated structure in which multilayer honeycomb structures are laminated. However, since the above honeycomb structure is strong in the thrust direction and hardly deforms, it is possible to realize a feature that is excellent in both compressive strength and strength in the thrust direction while making it thicker, that is, with a simple structure. .

  As shown in FIG. 2, the two inclined surfaces 1 are formed so as to extend inwardly from the parallel edges 3 inside the two opposing parallel edges 3 and to be inclined downward toward the center. The two inclined surfaces 1 in the figure have a shape formed by connecting two congruent rectangles 1X in a V shape. The bottom line at the center of the two inclined surfaces 1 forms parallel edges 3 opposite to the honeycomb-shaped opening edges on the opposite surface. The two inclined surfaces 1 made up of two rectangles 1X constitute the parallel edge 3 with the first sides of the rectangle 1X located at the upper and lower ends of the V-shape, and the rectangle 1X located on both sides of the two inclined surfaces 1 A boundary edge 2b with the tetracube 2 is formed on the second side.
