[0008] <1. First Embodiment> The honeycomb structure panel 1 according to the first embodiment of this disclosure will be described below with reference to the drawings. In this specification and in each drawing, elements similar to those already described will be denoted by the same reference numerals, and detailed descriptions will not be repeated.

[0009] (1.1. Usage status of honeycomb structure panel 1) The usage state of the honeycomb structure panel 1 according to the embodiment will be described with reference to the drawings. Figure 1 is a diagram showing an example of the usage state of the honeycomb structure panel 1 according to the first embodiment.

[0010] As shown in Figure 1, the honeycomb structure panel 1 is used by being placed on the upper surface of the roof of a house 100. In the illustrated example, the roof is made of a translucent material. In recent years, particularly in urban areas, extreme heat has persisted during the summer. One of the causes of this is the generation of radiant heat, which is emitted into the surroundings when the surface temperature of an object rises due to the heating of the material by sunlight.

[0011] When radiant heat from sunlight is transferred to the surface of the honeycomb structure panel 1, the shielding member 20, described later, promotes the reflection of infrared rays, thereby reducing the effects of radiant heat. In other words, in a house 100 equipped with the honeycomb structure panel 1, the transfer of radiant heat into the interior is suppressed by the honeycomb structure panel 1, thus suppressing the rise in temperature due to radiant heat from sunlight inside the house where people are located. The honeycomb structure panel 1 is particularly effective in the summer. In the illustrated example, the honeycomb structure panel 1 is placed on the upper surface of the roof of the house 100, but it may also be placed inside the house 100, such as in the ceiling. Furthermore, 1 is installed in a removable manner.

[0012] Figure 2 is a plan view of the honeycomb structure panel 1 shown in Figure 1. As shown in Figure 2, the honeycomb structure panel 1 has a rectangular shape with long and short sides in plan view. In the following description, the direction along the short side of the honeycomb structure panel 1 is called the vertical direction X (an example of the first direction), the direction along the long side of the honeycomb structure panel 1 is called the horizontal direction Y (an example of the second direction), and the direction along the thickness of the honeycomb structure panel 1 is called the thickness direction Z.

[0013] In the illustrated example, the honeycomb structure panel 1 is arranged in accordance with the movement of the sun. Specifically, the honeycomb structure panel 1 is preferably arranged such that the longitudinal direction X is along the north-south direction, and the lateral direction Y is along the east-west direction. Thereby, a light shielding effect can be ensured for a long period of time against the movement of the sun that travels from east to west relative to the ground surface. The specific structure of such a honeycomb structure panel 1 will be described below.

[0014] (1.2. Structure of Honeycomb Structure Panel 1 and Members) FIG. 3 is a perspective view (photograph) of a partial structure of the honeycomb structure panel 1 shown in FIG. 1. As shown in FIG. 3, the honeycomb structure panel 1 includes a rectangular frame body 10 and a shielding member 20 disposed inside the frame body 10. The frame body 10 extends in a longitudinal direction X and a lateral direction Y that are orthogonal to each other in a plan view. The shielding member 20 is disposed inside the frame body 10 and fixed to the frame body 10.

[0015] In the shielding member 20, core units 21 each having a plurality of cylindrical honeycomb shapes that are hexagonal in plan view are arranged and laid side by side in the longitudinal direction X and the lateral direction Y inside the frame body 10.

[0016] In the core unit 21, the central axis of the honeycomb shape is arranged to be inclined with respect to the thickness direction Z. In the example shown in FIG. 3, the cylindrical honeycomb shape that is hexagonal in plan view is arranged such that its central axis extends downward as it goes toward the near side in the thickness direction Z.

[0017] Figure 4 illustrates the cross-sectional structure of a portion of the honeycomb structure panel 1 shown in Figure 1. As shown in Figure 4, the walls of the core unit 21 are inclined to extend northward as they rise. In a cross-sectional view, the angle of the straight line connecting the upper end of a certain wall and the lower end of the adjacent wall located to its north (hereinafter referred to as the reference angle) is 79 degrees or more with respect to the horizontal plane. In the illustrated example, the reference angle is 79 degrees. The magnitude of the reference angle is set based on the standard solar altitude during the summer solstice, when the sun's altitude is highest in Japan. In other words, if the reference angle of the honeycomb-shaped wall is 79 degrees or more, sunlight can be blocked by the honeycomb-shaped wall surfaces arranged in a vertical X direction, even during the summer solstice when the sun's altitude is highest.

[0018] Next, the component structure and assembly process of the honeycomb structure panel 1 will be described. Figure 5 shows an example of the structure of the core unit 21 that makes up the honeycomb structure panel 1. The names of each component are as follows. • Core unit 21: A structure in which three honeycomb shapes are formed, it is a unit unit of the shielding member 20, and is composed of two half units 21A combined together. • Half unit 21A: The material that makes up half of the core unit 21, formed by press processing of a plate. • Plate: Sheet material before press bending to become half-unit 21A, for example, aluminum material. • Core assembly 22: A structure in which multiple core units 21 are arranged and connected side by side. • Shielding member 20: A structure in which multiple core assemblies 22 are stacked inside the frame 10.

[0019] In the example shown in Figure 5, the core assembly 22 is composed of four core units 21. Each core unit 21 is composed of two half units 21A. Each half unit 21A is composed of seven units, from the first to the seventh, which have different structures from each other.

[0020] In the illustrated example, the leftmost core unit 21 is composed of a combination of the first half unit 21A and the second half unit 21A. The core unit 21 to its right is composed of a combination of the fifth half unit 21A and the seventh half unit 21A. The core unit 21 to its right is composed of a combination of the sixth half unit 21A and the seventh half unit 21A. And the rightmost core unit 21 is composed of a combination of the third half unit 21A and the fourth half unit 21A.

[0021] Figure 6 is an enlarged view of the half unit 21A shown in Figure 5. This figure shows the first half unit 21A and the second half unit 21A that constitute the leftmost core unit 21 in Figure 5. Each half unit 21A has a diameter-adjusting protrusion 41 that projects outward in the thickness direction Z and a diameter-adjusting recess 42 that is recessed inward in the thickness direction Z at both end edges in the thickness direction Z. Multiple diameter-adjusting protrusions 41 and diameter-adjusting recesses 42 are arranged with spacing in the lateral direction Y.

[0022] As shown in Figure 5, in the half-unit 21A, which is composed of multiple types, the arrangement pattern of the diameter-fitting protrusions 41 and diameter-fitting recesses 42 differs depending on the position of the half-unit 21A in the core assembly 22. Multiple types of half-units 21A are provided mainly due to the differences in the arrangement pattern of the diameter-fitting protrusions 41 and diameter-fitting recesses 42.

[0023] As shown in Figure 6, in two half-units 21A facing each other in the vertical direction X, the diameter-matching protrusion 41 and diameter-matching recess 42 located in the middle portion in the horizontal direction Y constitute a connecting crimping portion 31 (first crimping portion) that connects the two half-units 21A that are close to each other in the vertical direction X. The connecting crimping portion 31 is composed of the diameter-matching protrusion 41 and diameter-matching recess 42 that connect the two half-units 21A to each other. In the connecting crimping portion 31, the two half-units 21A are connected to each other by bending the diameter-matching protrusion 41 so that it fits inside the diameter-matching recess 42.

[0024] Specifically, as shown in the enlarged view of Figure 6, with the first half unit and the second half unit facing each other and overlapping, the diameter-fitting protrusion 41 of the second half unit is bent so that it fits inside the diameter-fitting recess 42 of the first half unit. As a result, the diameter-fitting protrusion 41 bends from the front side to the back side of the honeycomb structure panel 1 and overlaps inside the diameter-fitting recess 42. This joins the first half unit and the second half unit. By forming the joining crimping portion 31 with the diameter-fitting protrusion 41 and the diameter-fitting recess 42 in this way, lateral Y-direction displacement is prevented and the dimensions during assembly are fixed. In addition, the diameter-fitting protrusion 41 and the diameter-fitting recess 42 act as guides during assembly, making it easier to align the first half unit and the second half unit.

[0025] As shown in Figure 5, a connecting crimping portion 32 (second crimping portion) is formed at the end of the core unit 21 in the lateral direction Y, connecting adjacent core units 21 in the lateral direction Y. The connecting crimping portion 32 consists of a diameter-matching projection 41 formed at one end of the core unit 21 in the lateral direction Y, and three diameter-matching recesses 42. In the connecting crimping portion 32, the diameter-matching projection 41 is fitted into the diameter-matching recesses 42 formed at the other end of the adjacent core unit 21 in the lateral direction Y, thereby connecting adjacent core units 21.

[0026] In other words, the connecting crimping portion 32 is composed of one diameter-fitting protrusion 41 formed on the half unit 21A and three diameter-fitting recesses 42 formed on the half unit 21A. In the connecting crimping portion 32, the two core units 21 are connected by bending the diameter-fitting protrusion 41 so that it fits inside the three diameter-fitting recesses 42. The core assembly 22 is then formed with the four core units 21 connected in the lateral direction Y.

[0027] Figure 7A shows the state in which the core assemblies 22 are laid out inside the frame 10, and Figure 7B is a view from arrow B in Figure 7A. In Figure 7A, the topmost core assembly 22 in the shown state is shown at a distance to help understand the units of the stacked core assemblies 22. Also, the upper and lower ends of the stacked core assemblies 22 are not shown in this figure.

[0028] As shown in Figure 7A, the core unit 21 has a laminated crimping portion 33 (third crimping portion) formed therein that joins adjacent core assemblies 22 in the vertical direction X, which is the stacking direction. The laminated crimping portion 33 is composed of the parts of the diameter-matching protrusions 41 and diameter-matching recesses 42 formed on the core unit 21 that are not used as joining crimping portions 31 and connecting crimping portions 32. Specifically, the diameter-matching protrusions 41 and diameter-matching recesses 42 formed on one side of the honeycomb shape of the core unit 21 function as the laminated crimping portion 33. In the laminated crimping portion 33, when the core assemblies 22 are stacked, the two core assemblies 22 are joined together by bending the lower diameter-matching protrusion 41 so as to fit inside the upper diameter-matching recess 42.

[0029] Furthermore, the core assembly 22 is stacked and fitted inside the frame 10. As shown in Figure 7B, multiple slits 11 are formed inside the frame 10, extending at an angle with respect to the thickness direction Z. The slits 11 are arranged at equal intervals in the vertical direction X. As shown in Figure 7A, the core assembly 22, which is composed of multiple core units 21, is fixed to the frame 10 by bending the ends E in the horizontal direction Y outwards, with the ends E of the core units 21 inserted into the slits 11 of the frame 10 (see view from arrow C).

[0030] In this way, the lateral Y end E of the core assembly 22 is bent outside the slit 11 of the frame 10, thereby firmly fixing the core assembly 22 to the frame 10 and preventing the core assembly 22 from falling out of the frame 10. Thus, the end E of the core assembly 22 and the slit 11 constitute a fourth crimping portion 34 that fixes the core assembly 22 to the frame 10.

[0031] Figure 8A shows the structure of the adjustment core units 23 positioned above and below the core assembly 22. Figure 8B is a side view of the lower adjustment core unit 23. As shown in Figure 8A, adjustment core units 23 are positioned at the upper and lower ends of the core assembly 22. The adjustment core unit 23 is composed of multiple panels. In the illustrated example, five adjustment core units 23 are arranged in a row in the lateral direction Y. As shown in Figure 8B, a portion of the adjustment core unit 23 (adjustment core unit 23a) is fixed to the lower or upper end of the frame 10 by rivets 23A. This firmly fixes the adjustment core unit 23 to the frame 10 without displacement.

[0032] The honeycomb structure panel 1 is manufactured through the following process. • First step: Process of forming the core unit 21 • Second step: The process of forming the core assembly 22. • Third step: Laminating the core assembly 22 inside the frame 10. • Step 4: The process of fixing the core assembly 22 inside the frame 10.

[0033] In the first step, multiple plates are first pressed and bent, and two of the resulting half units 21A are combined and joined together by a crimping joint 31. This forms a core unit 21 having multiple cylindrical honeycomb shapes.

[0034] In the second step, multiple core units 21 manufactured in the first step are arranged so that the honeycomb shape is aligned along the horizontal direction Y. Then, adjacent core units 21 are connected to each other by connecting crimping parts 32. This forms a core assembly 22 consisting of multiple core units 21.

[0035] In the third step, multiple core assemblies 22 manufactured in the second step are stacked in the vertical direction X and joined together by the stacking crimping section 33. This joins the core assemblies 22 that are aligned vertically to each other.

[0036] In the fourth step, the core assembly 22, which was stacked in the third step, is fixed to the inside of the frame 10. At this time, the end E of the core unit 21 located at the outer end in the lateral direction Y of the core assembly 22 is inserted into a slit 11 formed inside the frame 10, and the end E is bent to form a fourth crimped portion 34, thereby fixing the core assembly 22 to the frame 10. Finally, adjustment core units 23 are placed at the uppermost and lowermost ends of the core assembly 22, and a portion of the adjustment core unit 23 is fixed to the frame 10 by rivet fastening 23A. With these steps, the honeycomb structure panel 1 is completed.

[0037] (1.3.Summary) As described above, the honeycomb structure panel 1 in this disclosure comprises a frame 10 and a shielding member 20 that is arranged and fixed inside the frame 10. The shielding member 20 has core units 21 that are hexagonal in plan view, arranged and laid out inside the frame 10. Therefore, it is possible to provide a honeycomb structure panel 1 that exhibits a light-shielding effect while also having excellent design.

[0038] Furthermore, the core unit 21 is positioned so that the central axis of the honeycomb shape is inclined with respect to the thickness direction Z. Therefore, when the honeycomb structure panel 1 is positioned so that the thickness direction Z of the honeycomb structure panel 1 is aligned with the vertical direction, sunlight can be effectively shielded by the wall surface of the honeycomb-shaped cylinder.

[0039] Furthermore, the core unit 21 is fixed to the frame 10 by inserting its end E into the slit 11 and bending it to form a fourth crimped portion 34. This prevents misalignment between the core unit 21 and the frame 10.

[0040] Furthermore, a crimping portion is formed at the end of the core unit 21 in the first direction, which connects adjacent core units 21 to each other. Therefore, multiple core units 21 can be fixed together by connecting the members.

[0041] Furthermore, the crimping portion includes an engaging projection and an engaging recess, and adjacent core units 21 are connected when the engaging projection engages with the engaging recess. In this way, by engaging the pre-formed engaging projection of the core unit 21 with the engaging recess, it is possible to firmly fix it with a simple configuration without the need for other fastening parts.

[0042] Furthermore, adjustment core units 23 are positioned at the uppermost and lowermost ends of the core assembly 22, and a portion of the adjustment core unit 23 is fixed to the frame 10 by rivets 23A. In this way, the gaps at the upper and lower ends inside the frame 10 are filled, and the core assembly 22 can be more firmly fixed to the frame 10.

[0043] <2. Second Embodiment> Next, the structure of the honeycomb structure panel 1 according to the second embodiment will be described. Note that components similar to those in the first embodiment are denoted by the same reference numerals, and repeated explanations will be omitted. Figure 9 shows an example of the honeycomb structure panel 1 in use according to the second embodiment. Figure 9 is a front view of the honeycomb structure panel 1 shown in Figure 9.

[0044] As shown in Figure 9, the honeycomb structure panel 1 according to this embodiment can also be used as a screen for a house 200 or the like. In the illustrated example, the honeycomb structure panel 1 is erected on the outside of the house 200. As shown in Figure 10, the honeycomb structure panel 1 is arranged so that the vertical direction X is aligned with the vertical direction and the horizontal direction Y is aligned with the left-right direction. The honeycomb structure panel 1 may also be placed inside the house 200, as shown by the dashed line in Figure 9.

[0045] Figure 11 is a diagram illustrating the cross-sectional structure of the honeycomb structure panel 1. As shown in Figure 11, the honeycomb structure panel 1 is arranged such that the central axis of the honeycomb shape extends downward as it moves from the inside to the outside of the house. This effectively blocks the view from the outside to the inside of the house. Alternatively, as indicated by reference numeral 1B, the honeycomb structure panel 1 may be arranged so that the central axis of the honeycomb shape extends downward as it moves from the outside to the inside of the house.

[0046] <3. Third Embodiment> Next, with reference to Figures 12 and 13, the uses of the honeycomb structure panel 1 according to the third embodiment will be described. Figure 12 is a diagram showing a first example of use in the third embodiment. As shown in Figure 12, the honeycomb structure panel 1 may be used as a partition inside a house 300. In this case, because the honeycomb-shaped wall surface is inclined, it is possible to block the view from one side to the other in the thickness direction Z of the honeycomb structure panel 1, while ensuring ventilation and obtaining a rectifying effect. The honeycomb structure panel 1 may be placed inside the house 300 as shown by the dashed line in Figure 12, or it may be placed in a window or on the ceiling as a decorative panel for the interior, as indicated by reference numeral 1C.

[0047] Figure 13 shows a second example of use in the third embodiment. As shown in Figure 13, the honeycomb structure panel 1 may be used in applications similar to decorative blocks placed on a terrace. That is, by erecting the honeycomb structure panel 1 on a terrace, it is possible to block the view from the outside while allowing soft light and wind to enter. Furthermore, since the honeycomb structure panel 1 is composed of a cylindrical honeycomb shape, it has excellent ventilation and can also provide security by ensuring partial visibility from the inside of the house to the outside.

[0048] <4. Other variations> The configuration of the honeycomb structure panel 1 has been described above, but the application of the technical ideas of this disclosure is not limited to the above embodiments. For example, although an example has been shown in which one core assembly 22 is composed of four core units 21 in the honeycomb structure panel 1, this is not limited to this. The number of core units 21 that make up the core assembly 22 can be arbitrarily changed.

[0049] Furthermore, although the above embodiment shows a configuration in which the core assemblies 22 are stacked in the vertical direction X in the honeycomb structure panel 1, this is not limited to this configuration. In other words, the core assemblies 22 may be stacked in the horizontal direction Y.

[0050] Furthermore, although the core unit 21 is shown to have a configuration exhibiting three honeycomb shapes, the number of honeycomb shapes in the core unit 21 can be arbitrarily changed. Also, the core unit 21 may be a cylindrical structure with polygons other than hexagons.

[0051] Furthermore, it is also possible to realize a honeycomb structure panel that has at least two of the functions of the first to third embodiments described above. That is, it is possible to realize a honeycomb structure panel that has at least two of the following functions: the light-shielding function of the honeycomb structure panel 1 as the first embodiment, the function of privacy provided by the honeycomb structure panel 1 as the second embodiment, and the aesthetic and ventilation functions provided by the honeycomb structure panel 1 as the third embodiment.

[0052] While several embodiments of this disclosure have been illustrated above, these embodiments are provided as examples only and are not intended to limit the scope of the invention. These embodiments can be implemented in a variety of other forms, and various omissions, substitutions, combinations, and modifications are possible. These embodiments and their variations are included in the scope and essence of the invention, as well as in the claims and their equivalents. Furthermore, the embodiments described above can be implemented in combination with each other. [Explanation of Symbols]
