[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that each drawing is a schematic view and may differ from the actual one. In addition, the following embodiment illustrates an apparatus and method for embodying the technical idea of ​​the present invention, and does not specify the configuration as described below. In other words, the technical idea of ​​the present invention can be modified in various ways within the technical scope described in the claims.

[0009] First Embodiment "composition" In the following description, the three mutually perpendicular directions are referred to as a vertical direction, a width direction, and a thickness direction. FIG. 1 is a diagram showing a panel structure 11 of the first embodiment. (a) in the figure shows the panel structure 11 as viewed from one side in the width direction, one side in the length direction, and one side in the thickness direction. (b) in the figure shows the panel structure 11 as viewed from one side in the thickness direction. The panel structure 11 is a metal surface material along the width direction and length direction, with both ends in the width direction bent at approximately right angles toward one side in the thickness direction, forming an approximately U-shape as viewed from the length direction.

[0010] The panel structure 11 is formed with an uneven band 12 that is concave or convex in the thickness direction and extends in a band shape along the vertical direction of the surface direction. The uneven band 12 is embossed, and has a convex shape that is convex toward the front when viewed from one side in the thickness direction, and a concave shape that is concave toward the back when viewed from the other side in the thickness direction. The cross-sectional shape of the uneven band 12 is, for example, a trapezoid whose dimensions decrease toward the top surface of the convex shape or the bottom surface of the concave shape. The uneven band 12 extends along the bending direction in which the panel structure 11 is curved under a bending load, and extends from one end side in the vertical direction to the other end side at the center in the width direction. The bending load is a load that tries to bend both ends in the vertical direction in either one direction or the other direction in the thickness direction when viewed from the width direction. The panel structure 11 can achieve any rigidity by adjusting the arrangement of the uneven band 12, the width in the short side direction, the length in the long side direction, and the height in the thickness direction.

[0011] FIG. 2 is a diagram showing the electrical equipment storage facility 15. As shown in FIG. The electrical equipment storage facility 15 is an electrical board that employs the panel structure 11 and stores electrical equipment therein. For example, electrical boards such as control boards, distribution boards, and switchboards are assumed, but the panel structure 11 can also be applied to the outer box of a cubicle-type high-voltage power receiving facility. Since the panel structure 11 has an uneven shape formed on the surface material, it is desirable to use the panel structure 11 so that one side in the thickness direction faces the inside of the electrical equipment storage facility 15 to suppress outward protrusion. Alternatively, the panel structure 11 may be covered with a design panel, or the panel structure 11 may be used as an internal partition wall of the electrical equipment storage facility 15.

[0012] <Action and Effect> Next, main effects of the first embodiment will be described. The panel structure 11 is formed with uneven bands 12 that are concave or convex in the thickness direction and extend in a band shape along the surface direction. In this way, by providing the uneven bands 12 only at necessary locations rather than forming the uneven shape uniformly over the entire surface direction, it is possible to increase rigidity while reducing weight. In the panel structure 11, the uneven band 12 extends along the bending direction in which the panel curves when subjected to a bending load. This increases the rigidity in the bending direction. The uneven band 12 increases the rigidity against a load that tends to bend both ends in the vertical direction in either direction in the thickness direction when viewed from the width direction. The electrical equipment storage facility 15 employs a panel structure 11 and stores electrical equipment therein. This makes it possible to provide a product that is lightweight while increasing rigidity.

[0013] Comparative Example Here, a panel structure in which alternating concave and convex shapes are formed over the entire surface will be described as a comparative example. By uniformly forming the concave and convex shapes over the entire surface, the overall rigidity can be increased, but the concave and convex shapes cause undulations in the thickness direction, which causes a problem of increased weight. In addition, forming the concave and convex shapes over the entire surface will complicate the embossing mold and rolls, which will lead to increased costs.

[0014] <<Variation>> In the first embodiment, a configuration has been described in which the uneven bands 12 extending in a band shape along the vertical direction among the surface directions are formed, but the present invention is not limited to this. FIG. 3 is a diagram showing a modified example. (a) in the figure shows the panel structure 11 as viewed from one side in the width direction, one side in the length direction, and one side in the thickness direction. (b) in the figure shows the panel structure 11 as viewed from one side in the thickness direction. Since this is the same as the first embodiment described above, except that the direction in which the uneven bands extend is different, a detailed description of the common configuration will be omitted.

[0015] The panel structure 11 is formed with an uneven band 13 extending in a band-like shape along the width direction of the surface direction. The uneven band 13 extends along the bending direction in which the panel structure 11 is curved under a bending load, and extends from one end side to the other end side in the width direction at the center in the vertical direction. The bending load is a load that tries to bend both ends in the width direction in one direction or the other in the thickness direction when viewed from the vertical direction. In this way, since the uneven shape is not formed over the entire surface direction, it is possible to increase rigidity while reducing weight. The uneven band 13 can increase rigidity against a load that tries to bend both ends in the width direction in one direction or the other in the thickness direction when viewed from the vertical direction.

[0016] Second Embodiment "composition" In the second embodiment, multiple intersecting uneven bands are formed, but the other configurations are similar to those of the first embodiment described above, so the same symbols are used for the common configurations and detailed descriptions are omitted. FIG. 4 is a diagram showing a panel structure 11 according to the second embodiment. (a) in the figure shows the panel structure 11 as viewed from one side in the width direction, one side in the length direction, and one side in the thickness direction. (b) in the figure shows the panel structure 11 as viewed from one side in the thickness direction. The panel structure 11 is formed with one uneven band 12 extending in a band-like shape along the length direction of the surface, and one uneven band 13 extending in a band-like shape along the width direction. The uneven bands 12 and 13 cross each other in a cross shape.

[0017] <Action and Effect> Next, the main effects of the second embodiment will be described. The panel structure 11 is formed with intersecting uneven bands 12 and 13. This makes it possible to increase rigidity against a plurality of bending directions. The uneven band 12 can increase rigidity against a load that bends both ends in the vertical direction in either one direction or the other in the thickness direction when viewed from the width direction. The uneven band 13 can increase rigidity against a load that bends both ends in the width direction in either one direction or the other in the thickness direction when viewed from the vertical direction. Other effects brought about by the common configuration are similar to those of the first embodiment described above.

[0018] <<Variation>> In the second embodiment, the uneven bands 12 extending in the vertical direction and the uneven bands 13 extending in the width direction cross each other in a cross shape, but the present invention is not limited to this. FIG. 5 is a diagram showing a modified example. (a) in the figure shows the panel structure 11 as viewed from one side in the width direction, one side in the length direction, and one side in the thickness direction. (b) in the figure shows the panel structure 11 as viewed from one side in the thickness direction. Except for the fact that one of the uneven bands 12 extends preferentially and the other uneven band 13 is cut off, this is the same as the first embodiment described above, so detailed explanations of the common configurations will be omitted.

[0019] In the panel structure 11, intersecting uneven bands 12 and 13 are formed, with one uneven band 12 extending preferentially and the other uneven band 13 being separated. That is, one uneven band 12 extending vertically is formed in the center in the width direction, and one uneven band 13 extending widthwise is formed on each side of the uneven band 12 in the width direction. In this way, by prioritizing one side and separating the other, the embossing mold can be simplified and an increase in costs can be suppressed. In the modified example, a configuration in which one of the uneven bands 12 extends preferentially and the other uneven band 13 is divided has been described, but the present invention is not limited to this. That is, a configuration in which one of the uneven bands 13 extends preferentially and the other uneven band 12 is divided may also be used.

[0020] Third Embodiment "composition" In the third embodiment, an uneven band is formed around the opening, and the other configurations are similar to those of the second embodiment described above. Therefore, the common configurations are given the same symbols and detailed descriptions are omitted. FIG. 6 is a diagram showing a panel structure 11 according to the third embodiment. FIG. 1A shows the panel structure 11 as viewed from one side in the width direction, one side in the length direction, and one side in the thickness direction. FIG. 1B shows the panel structure 11 as viewed from one side in the thickness direction. The panel structure 11 has an opening 14 formed therethrough in the thickness direction. The opening 14 is rectangular as viewed from the thickness direction, and is formed in the center in the width direction and the center in the length direction. On each side of the opening 14 in the width direction, an uneven band 12 extending in the length direction is formed, and on each side of the opening 14 in the length direction, an uneven band 13 extending in the width direction is formed. The uneven bands 12 and the uneven bands 13 are formed in a crisscross pattern.

[0021] <Action and Effect> Next, main effects of the third embodiment will be described. The panel structure 11 has an opening 14 penetrating in the thickness direction, and an uneven band 12 and an uneven band 13 are formed around the opening 14. This makes it possible to reinforce the periphery of the opening 14 and suppress a decrease in rigidity. Other advantageous effects brought about by the common configuration are similar to those of the second embodiment described above.

[0022] Fourth Embodiment "composition" In the fourth embodiment, multiple uneven bands are arranged in a band-like shape, and the other configurations are similar to those of the first embodiment described above, so the same symbols are used for the common configurations and detailed descriptions are omitted. FIG. 7 is a diagram showing a panel structure 11 according to the fourth embodiment. (a) in the figure shows multiple uneven bands 12 as viewed from the thickness direction. Multiple uneven bands 12 are arranged in strips along the vertical direction, and are staggered at equal intervals. (b) in the figure shows multiple uneven bands 13 as viewed from the thickness direction. Multiple uneven bands 13 are arranged in strips along the width direction, and are staggered at equal intervals.

[0023] <Action and Effect> Next, main effects of the fourth embodiment will be described. A plurality of uneven bands 12 (or uneven bands 13) are arranged in a band shape. This allows each uneven band 12 (or uneven band 13) to be small, making it easy to manufacture embossing dies and rolls. The plurality of uneven bands 12 (or uneven bands 13) are arranged in a staggered manner, so that any one of the uneven bands 12 (or uneven bands 13) can bear the bending load, thereby increasing rigidity. A plurality of uneven bands 12 (or uneven bands 13) are arranged at equal intervals. This ensures that one of the uneven bands 12 (or uneven bands 13) can withstand bending load, increasing rigidity. In addition, because it can be patterned, it is possible to suppress increases in costs. Other advantageous effects brought about by the common configuration are similar to those of the first embodiment described above.

[0024] <<Variation>> In the fourth embodiment, the configuration has been described in which the uneven bands 12 extending in the vertical direction and the uneven bands 13 extending in the width direction are formed separately, but the present invention is not limited to this. FIG. 8 is a diagram showing a modified example. (a) in the figure shows the multiple uneven bands 12 and the multiple uneven bands 13 as viewed from the thickness direction. The multiple uneven bands 12 and the multiple uneven bands 13 cross each other. In this way, the cross shape can be achieved by adjusting the width in the short direction, the length in the long direction, and the spacing. (b) in the figure shows the multiple uneven bands 12 and the multiple uneven bands 13 as viewed from the thickness direction. The multiple uneven bands 12 and the multiple uneven bands 13 cross each other, with one of the multiple uneven bands 12 extending preferentially and the other multiple uneven bands 13 being cut off. In this way, by giving priority to one and cutting off the other, embossing can be easily performed.

[0025] Although the above description has been given with reference to a limited number of embodiments, the scope of the invention is not limited thereto, and modifications of the embodiments based on the above disclosure will be obvious to those skilled in the art. [Explanation of symbols]
