MODE FOR CARRYING OUT THE INVENTION
[0009] Hereinafter, embodiments of the connecting structure of the panel structure according to the present disclosure will be described based on the drawings. Note that the present invention is not limited by this embodiment. In addition, the constituent elements in the following embodiments include those that can be replaced by those skilled in the art and are easy to replace, or those that are substantially the same.
[0010] Figure 1 shows an example of a connecting structure 100 according to this embodiment. The connecting structure 100 shown in Figure 1 comprises a plurality of panel structures 10 and connecting members 20. The plurality of panel structures 10 are, for example, rectangular in shape and are connected with their end sides 11 facing each other. Multiple connecting members 20 are arranged in the direction D of the end sides 11.
[0011] Figure 2A is a diagram showing the configuration along the AA section in Figure 1. Figure 2A is a cross-sectional view showing an example of a connecting portion of a plurality of panel structures 10. In the example shown in Figure 2A, the connecting member 20 is, for example, cylindrical. As shown in Figure 2A, the panel structure 10 comprises a core member 12, a face plate 14, and a joint 16.
[0012] The core member 12 and the faceplate 14 are formed using a composite material. Preferably, the composite material is a thermoplastic fiber reinforced plastic (FRP) containing reinforcing fibers. Preferably, the fiber reinforced plastic is, for example, glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP). However, the fiber reinforced plastic is not limited to these.
[0013] The core member 12 is formed in a corrugated shape. The core member 12 has a plurality of protrusions 18 on both sides. On the side opposite to the direction of protrusion of the protrusions 18, the core member 12 has recesses at positions corresponding to the protrusions 18. Such a core member 12 may also be called a corrugated shape.
[0014] The faceplate 14 is positioned to sandwich the core member 12 from both sides in the height direction of the protrusion 18. The faceplate 14 is positioned on the protrusion 18 of the core member 12. The faceplate 14 is formed using a composite material. Preferably, the composite material is a thermoplastic fiber reinforced plastic (FRP) containing reinforcing fibers. Preferably, the fiber reinforced plastic is, for example, glass fiber reinforced plastic (GFRP) or carbon fiber reinforced plastic (CFRP). The fiber reinforced plastic is not limited to these. The core member 12 and the faceplate 14 may be formed from the same material or from different materials.
[0015] The joint 16 connects the core member 12 and the faceplate 14. The joint 16 is formed between the top of the protrusion 18 and the faceplate 14. The joint 16 is selectively formed between, for example, the tops of multiple protrusions 18 and the faceplate 14. The joint 16 is formed, for example, according to the rigidity and impact resistance characteristics required for the panel structure 10. The joint 16 can be formed by heating and melting the joint between the top of the protrusion 18 and the faceplate 14, then placing the faceplate 14 and cooling it. Heating can be performed using, for example, a heat source such as a heater and heating wire, ultrasonic vibration, electromagnetic induction by a magnetic field, and a laser, but is not limited to these methods. The joint 16 may also be configured such that the protrusion 18 and the faceplate 14 are joined using an adhesive (not shown).
[0016] In the panel structure 10, a space K is formed in the area enclosed by the core member 12 and the faceplate 14. In the panel structure 10, a protrusion 18 is formed on the core member 12 at the end edge 11 to be connected. Therefore, the panel structure 10 has a space K formed at the end edge 11.
[0017] The connecting member 20 is inserted into the space K at the end edge 11 of the panel structure 10. The connecting member 20 connects the panel structures 10 together. The connecting member 20 is formed, for example, in the shape of a rod extending in one direction. One end of the connecting member 20 is inserted into the space K of one panel structure 10, and the other end is inserted into the space K of the other panel structure 10.
[0018] In this embodiment, the hardness of the core member 12 and the faceplate 14 may be higher or lower than the hardness of the connecting member 20. If the hardness of the core member 12 and the faceplate 14 is higher than that of the connecting member 20, the core member 12 and the faceplate 14 can stably hold the connecting member 20. If the hardness of the core member 12 and the faceplate 14 is lower than that of the connecting member 20, the forces applied to the core member 12 and the faceplate 14 via the connecting member 20 can be flexibly received.
[0019] The connecting member 20 is supported in the space K by the protrusion 18 and the faceplate 14. Furthermore, in the space K, the connecting member 20 is held by the protrusion 18, sandwiched between both sides of the end edge 11 in the end edge direction D. Thus, the connecting member 20 can be configured to be supported in at least three places by, for example, the protrusion 18 and the faceplate 14. The portion of the connecting member 20 that is supported is not limited to point support (support by a line) as shown in the example in Figure 2A, but may also be supported by a line (support by a surface) as shown in the example in Figure 2A.
[0020] Figure 2B is an enlarged view of a portion of the space K of the panel structure 10. In Figure 2B, if the spacing between the protrusions 18 is p, the height of the protrusions 18 is h, and the thickness of the core member 12 is t, then the radius r of the connecting member 20 is:

[0021] Figures 3A and 4A are cross-sectional views showing another example of a state in which a connecting member is inserted into the space K of the panel structure 10. Figures 3B and 4B are enlarged views showing a part of the space K of the panel structure 10 shown in Figures 3A and 4A. In the example shown in Figures 3A and 4A, the connecting members 20A and 20B are, for example, triangular prisms. The connecting members 20A and 20B may have rounded corners in cross-sectional view. The connecting members 20A and 20B are supported in the space K by the protrusion 18 and the faceplate 14. In addition, the connecting members 20A and 20B are held in the space K by being sandwiched between the protrusion 18 from both sides in the edge direction D of the end edge 11. The connecting members 20A and 20B are supported at least three places by the protrusion 18 and the faceplate 14.
[0022] In Figure 3B, if the spacing between the protrusions 18 is p, the height of the protrusions 18 is h, and the thickness of the core member 12 is t, then the height x and the length y of the base of the connecting member 20A are:

[0023] Furthermore, in Figure 4B, if the spacing between the protrusions 18 is p, the height of the protrusions 18 is h, and the thickness of the core member 12 is t, then the cross-sectional area S of the connecting member 20B is:
number
[0024] Figure 5A is a cross-sectional view showing an example of a state in which a connecting member 20C is inserted into the space K of the panel structure 10. Figure 5B is an enlarged view of a part of the space K of the panel structure 10 shown in Figure 5A. In the example shown in Figure 5A, the connecting member 20C is, for example, a rectangular prism shape. The connecting member 20C is supported in the space K by the protrusion 18 and the faceplate 14. In addition, the connecting member 20C is held in the space K by being sandwiched between the protrusion 18 from both sides in the edge direction D of the end edge 11. In this way, the connecting member 20C is supported in at least three places by the protrusion 18 and the faceplate 14.
[0025] In Figure 5B, if the spacing between the protrusions 18 is p, the height of the protrusions 18 is h, and the thickness of the core member 12 is t, then the height x and the length y of the base of the connecting member 20C are:
number
[0026] Figure 6 is a cross-sectional view showing another example of a state in which a connecting member is inserted into the space K of the panel structure 10. As shown in Figure 6, the connecting member 20 may be bonded to the protrusion 18 and the faceplate 14 by adhesive 30. This configuration allows the connecting member 20 to be stably fixed to the panel structure 10. In this case, the adhesive 30 can be, for example, a thermoplastic resin. With this configuration, the adhesive strength can be reduced by applying heat to the adhesive 30, so that the connecting structure 100 of the panel structure 10 can be easily disassembled, for example.
[0027] Figure 7A shows another configuration of the connecting member. Figure 7B shows the connecting member 20E shown in Figure 7A viewed in the direction of arrow E. As shown in Figures 7A and 7B, the connecting member 20E can be configured using a linear member 21 made of metal and a commingle material 22 covering the linear member 21. The commingle material 22 can be, for example, a mixed material of reinforcing fibers and thermoplastic resin fibers. The connecting member 20E can be bonded to the protrusion 18 and the faceplate 14 by, for example, applying heat to the linear member 21 to melt the thermoplastic resin and then solidifying it. The adhesive strength can also be reduced again by applying heat to the linear member 21. Plug members 23 may be provided at both ends of the commingle material 22 to prevent the outflow of the melted thermoplastic resin. The plug members 23 seal the connecting member 20E between the protrusion 18 and the faceplate 14. With this configuration, bonding and release between the connecting member 20E and the protrusion 18 and the faceplate 14 can be easily switched.
[0028] Figure 8 shows another configuration of the connecting member. As shown in Figure 8, the connecting member 20F can be formed using a foaming agent. In this case, the foaming agent 25, which has been formed into a rod shape, is inserted into the space K of the panel structure 10 before foaming, and the volume of the foaming agent 25 is expanded by foaming it immediately before or after insertion to form the connecting member 20F. Various materials can be used as the foaming agent, such as materials that foam with water or materials that foam with gas.
[0029] Figure 9 shows another configuration of the connecting member. As shown in Figure 9, the connecting member 20 inserted into at least one panel structure 10G can be formed using a magnetic member 20G. In this case, a separate magnetic force generating member 20H capable of generating a magnetic force that attracts each other with the magnetic member 20G can be inserted into the other panel structure 10H as the connecting member 20. Examples of such a magnetic force generating member 20H include a magnetic material member or a magnetic material member. The magnetic force generating member 20H may also be a magnetic powder. The magnetic member 20G and the magnetic force generating member 20H can be fixed to the panel structures 10G and 10H, for example, by an adhesive.
[0030] Figures 10A and 11A show other configurations of the connecting member. As shown in Figure 10A, the connecting member 20I may be provided in a state where multiple connecting members 40 are connected along the edge direction D of the edge 11 of the panel structure 10.
[0031] Figure 10B shows the connecting member 20I shown in Figure 10A as viewed in the direction of arrow I. In the example shown in Figure 10A, the connecting member 20I inserted into one panel structure 10 to be connected and the connecting member 20I inserted into the other panel structure 10 extend in opposite directions from the connecting member 40 when viewed from the edge direction D of the edge 11.
[0032] Figures 11A and 11B show other configurations of the connecting member when viewed from the direction corresponding to the direction of arrow I in Figure 10A. In the example shown in Figure 11A, the connecting member 20J inserted into one panel structure 10 to be connected and the connecting member 20J inserted into the other panel structure 10 extend outwards at a 90° angle with respect to the connecting member 40 when viewed from the edge direction D of the edge 11. In this way, multiple connecting members 20J may be arranged so that, when viewed from the edge direction D of the edge 11, they extend outwards from the connecting member 40 in opposite directions to each other. This configuration allows the angle between the panel structures 10 to be connected to be set to a predetermined angle. Furthermore, although the example shown in Figure 11A shows a configuration with two connecting members 20J, it is not limited to this. For example, as shown in Figure 11B, three or more connecting members 20J (three examples are shown in Figure 11B) may be provided so as to extend outwards from a single connecting member 40. In this case, three or more panel structures 10 can be connected.
[0033] In the above embodiments, the configuration in which the core member 14 is corrugated was used as an example for explanation, but the invention is not limited to this. The core member 14 is not limited to a corrugated shape as long as it is formed in a plate shape and has a plurality of protrusions on at least one surface.
[0034] Figure 12 shows another configuration of the connecting member. As shown in Figure 12, the connecting member 20K may be provided in a state where multiple connecting members 40 are connected via hook portions 26 along the end edge direction D of the end edge 11 of the panel structure 10. The hook portions 26 are rotatably provided with respect to the connecting member 40. In this configuration, the angle between the panel structures 10 can be adjusted while the panel structures 10 are connected to each other.
[0035] Figure 13 shows a connecting structure 200 according to another example. As shown in Figure 13, the connecting structure 200 comprises a plurality of panel structures 110 to be connected and a connecting member 120. In the panel structure 110, the core member 112 is formed in a wave shape such that the space K surrounded by the protrusion 118 and the face plate 114 penetrates the panel structure 110 along the edge direction D.
[0036] The connecting member 120 is inserted into the panel structure 110 so as to penetrate the space K. The connecting member 120 has a first insertion portion 121 that is inserted in one direction into one of the panel structures 110 to be connected, a second insertion portion 122 that is inserted in one direction into the other panel structure 110, and a connecting portion 123 that connects the first insertion portion 121 and the second insertion portion 122. The first insertion portion 121 and the second insertion portion 122 are provided so as to be able to rotate relative to the panel structure 110 with respect to a central axis parallel to the panel structure 110 in one direction. Therefore, when the multiple panel structures 110 are connected by the connecting member 120, their angles can be adjusted with respect to the connecting member 120. In the configuration shown in Figure 13, the angles of the multiple panel structures 110 may be adjusted to a predetermined angle, and then the adjusted angle may be fixed by attaching the cap member 124.
[0037] The connecting member 120 is provided so as to be separable in one direction for each of the first insertion portion 121, the second insertion portion 122, and the connecting portion 123. Figure 14 shows an example of the process of connecting panel structures 110 together using a connecting member 120 according to another example. In this configuration, when connecting panel structures 110 together using the connecting member 120, as shown in Figure 14, the connecting member 120 is first divided in one direction. Then, the first insertion portion 121A and the second insertion portion 122A are inserted into one of the divided pieces 120A from one side of the panel structure 110, and the first insertion portion 121A and the second insertion portion 122A are inserted into the other divided piece 120B from the other side of the panel structure 110. Subsequently, the first insertion portion 121A, the second insertion portion 122A, and the connecting portion 123A of the divided piece 120A are joined to the first insertion portion 121B, the second insertion portion 122B, and the connecting portion 123B of the divided piece 120B at the locking portions 121C, 122C, and 123C, respectively.
[0038] Figure 15A shows a connecting structure 300 according to another example. Figure 15B shows the connecting member 220 shown in Figure 15A as viewed in the direction of arrow R. As shown in Figures 15A and 15B, the connecting structure 300 comprises a plurality of panel structures 210 to be connected and a connecting member 220. In the panel structure 210, the core member 212 is formed in a wave shape such that the space K surrounded by the protrusion 218 and the face plate 214 penetrates the panel structure 210 in one direction. The plurality of panel structures 210 also have a plurality of rectangular notches 230 in the part into which the connecting member 220 is inserted. The plurality of panel structures 210 are cut out by the notches 230 to form a plurality of rectangular parts 231. The plurality of panel structures 210 are arranged such that the rectangular parts 231 of one panel structure 210 and the notches 230 of the other panel structure 210 fit together in one direction.
[0039] The connecting member 220 is positioned to penetrate the rectangular portion 231 of each panel structure 210. The connecting member 220 is provided so as to be rotatable relative to each rectangular portion 231 about a central axis parallel to one direction. Therefore, when the multiple panel structures 110 are connected by the connecting member 220, their angles can be adjusted about the connecting member 220. In the configuration shown in Figure 14, the angles of the multiple panel structures 210 may be adjusted to a predetermined angle, and then the adjusted angle may be fixed by attaching the cap member 224.
[0040] Furthermore, although the above embodiment described an example in which the shape of the portion of the connecting member inserted into the space K is columnar, the invention is not limited to this. The shape of the portion of the connecting member inserted into the space K may also be cone-shaped. In this case, the connecting member can be cone-shaped, with the tip that is inserted into the space K becoming thinner.
[0041] As described above, the panel structure connecting structure according to the first aspect of this disclosure comprises a plurality of panel structures 10, each having a core member 12 formed in a plate shape using a composite material and having a plurality of protrusions 18 on at least one surface, and a face plate 14 made of a composite material and arranged so as to sandwich the core member 12 from both sides in the height direction of the protrusions 18, and a connecting member 20 that is inserted into the space K surrounded by the protrusions 18 and the face plate 14 in the plurality of panel structures 10 and connects the panel structures 10 to each other.
[0042] With this configuration, the panel structures 10 are connected to each other by inserting the connecting member 20 into the space K surrounded by the protrusion 18 and the face plate 14 at the end edge 11 of the multiple panel structures 10, thus enabling a stable connection between the panel structures 10.
[0043] The connecting structure for a panel structure according to a second aspect of this disclosure is the same as the connecting structure for a panel structure according to a first aspect, wherein a plurality of panel structures 10 have protrusions 18 formed on their end edges 11, the end edges 11 on which the protrusions 18 are formed are arranged facing each other, and a plurality of protrusions 18 are formed so as to be aligned in the end edge direction D, which is the direction in which the opposing end edges 11 extend, and the connecting member 20 is supported by the protrusions 18 and the faceplate 14 at the opposing end edges 11 of each panel structure 10, and is held by the protrusions 18 in a state where it is sandwiched from both sides in the end edge direction D, which is the direction in which the end edges 11 extend.
[0044] In this configuration, multiple panel structures 10 are arranged so that the protrusions 18 formed on the end edges 11 face each other, and are connected by a connecting member 20. Therefore, multiple panel structures 10 can be easily connected by the connecting member 20.
[0045] The connecting structure for a panel structure according to a third aspect of this disclosure is the same as the connecting structure for a panel structure according to a second aspect, wherein the connecting member 20 is supported at least three places by the protrusion 18 and the faceplate 14.
[0046] With this configuration, the connecting member 20 can be stably held by the protrusion 18 and the faceplate 14.
[0047] The connecting structure for a panel structure according to the fourth aspect of this disclosure is the connecting structure for a panel structure according to the second aspect, wherein the connecting member 20 is bonded to the protrusion 18 and the faceplate 14 with an adhesive 30.
[0048] With this configuration, the connecting member 20 can be stably held between the protrusion 18 and the faceplate 14 using adhesive 30.
[0049] The connecting structure for a panel structure according to the fifth aspect of this disclosure is the same as the connecting structure for a panel structure according to the fourth aspect, wherein the adhesive 30 is a thermoplastic resin.
[0050] With this configuration, the adhesive strength of the connecting member 20 can be reduced by applying heat to the adhesive 30. Therefore, the panel structure 10 can be easily connected and disconnected.
[0051] The connecting structure for a panel structure according to the sixth aspect of this disclosure is the connecting structure for a panel structure according to the second aspect, wherein the connecting member 20 is formed using a linear member 21 made of metal and a commingle material 22 covering the linear member 21.
[0052] With this configuration, applying heat to the linear member 21 melts a portion of the commingling material 22, thereby reducing the adhesive strength of the connecting member 20. Therefore, the panel structure 10 can be easily connected and disconnected.
[0053] The connecting structure for a panel structure according to the seventh aspect of this disclosure is the connecting structure for a panel structure according to the second aspect, wherein the connecting member 20F is formed using a foaming agent.
[0054] With this configuration, the foaming agent is inserted into the space K beforehand, and by foaming it in this state to expand its volume, the connecting member 20F can be easily filled into the space K.
[0055] The panel structure connecting structure according to the eighth aspect of this disclosure is a panel structure connecting structure according to the second aspect, wherein a magnetic member 20G is inserted as a connecting member into one panel structure 10, and a magnetic force generating member 20H is inserted into the other panel structure 10, which generates a magnetic force with the magnetic member 20G, and the one panel structure 10 and the other panel structure 10 are connected by attracting each other with magnetic force.
[0056] With this configuration, multiple panel structures 10 can be easily connected by the magnetic force generated between the magnetic member 20G and the magnetic force generating member 20H.
[0057] The panel structure connection structure according to the ninth aspect of this disclosure is provided in which, in the panel structure connection structure according to the second aspect, the connecting members 20I and 20J are connected in a plurality of manner by connecting members 40 along the edge direction D of the edge 11.
[0058] With this configuration, since multiple connecting members 20I and 20J are connected by the connecting member 40, the number of parts can be reduced. Furthermore, by providing, for example, three or more connecting members 20 extending from a single connecting member 40, three or more panel structures 10 can be connected by a single connecting member 40.
[0059] The panel structure connecting structure according to the tenth aspect of this disclosure is a panel structure connecting structure according to the ninth aspect, wherein a connecting member 20I inserted into one panel structure 10 and a connecting member 20I inserted into the other panel structure 10 are provided so as to extend in opposite directions when viewed from the edge direction D of the edge 11.
[0060] With this configuration, the connecting member 20I inserted into one panel structure 10 and the connecting member 20I inserted into the other panel structure 10 extend in opposite directions when viewed from the edge direction D of the edge 11, so that the panel structures 10 can be properly connected along the planar direction.
