This makes it easier to fix the composite panel to the base, and the workability is also excellent. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-40395 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, there is a demand for improved reliability in the mounting structure of such a composite panel to the base portion from the viewpoint of preventing the composite panel from falling off, etc. For example, there is a demand for improved mounting strength and durability of the composite panel. [Means for solving the problem]

[0005] a mounting structure for a composite panel for solving the above-mentioned problems, which is a mounting structure for fixing a composite panel, which is formed by fixing a finishing material to one surface of a honeycomb panel, to a base portion, the honeycomb panel comprising a honeycomb core, a top plate fixed to a top surface of the honeycomb core, and a bottom plate fixed to a bottom surface of the honeycomb core, the finishing material being fixed to the top plate, the mounting structure comprising a hole provided in the honeycomb panel from the bottom plate side, a nut portion inserted into the hole, and a flange portion extending from one end of the nut portion, and a fixing nut, which is disposed in the hole and in which the flange portion is disposed around the hole in the bottom plate, the flange portion being positioned around the hole on the bottom plate and fixed to the bottom plate, the composite panel being fixed to the base portion by tightening a bolt to the nut portion via a mounting member for connecting to the base portion.

[0006] According to the above-mentioned configuration, the composite panel, which is made lighter by fixing the finishing material to the honeycomb panel, can be firmly fixed to the base. That is, the composite panel is attached to the base via the mounting member. The mounting member is fixed to the honeycomb panel by tightening the bolt into the fixing nut fixed to the honeycomb panel.

[0007] Since composite panels are lightweight, the structure of the base can be changed, for example, from a steel frame base to a lightweight steel frame base. This simplifies the mounting structure for the base, making it possible to narrow the space behind the composite panel. This in turn makes it possible to increase the effective living space and floor area.

[0008] In the above-mentioned composite panel mounting structure, the nut portion may be fixed in the hole by an adhesive. According to the above-mentioned configuration, the fixing nut is fixed to the hole by the adhesive force of the adhesive in addition to the welding. Therefore, the mounting strength of the fixing nut to the honeycomb panel can be further increased.

[0009] In the mounting structure for the composite panel, the flange may be located around the hole on the bottom plate and welded to the bottom plate. According to the above configuration, the flange of the fixing nut is fixed to the honeycomb panel by welding, and is fixed more firmly than when it is fixed only by adhesive. During construction, the composite panel is handled as a single unit with the fixing nut fixed. Therefore, at the construction site, the composite panel only needs to be fixed to the base via the mounting member. Therefore, the construction work is simplified and made easier, and work efficiency can be improved.

[0010] In the above-mentioned composite panel mounting structure, the flange may be welded to the bottom plate at a position inside the outer circumferential end of the flange. According to the above-mentioned configuration, the flange is fixed to the bottom plate at a position inside the outer circumferential end of the flange, thereby increasing the welding strength of the anchor nut to the honeycomb panel.

[0011] In the above-mentioned mounting structure for a composite panel, the fixing nut may include a crimp nut located around the hole and fixed to the bottom plate by crimping, and a double screw nut having threads on the inner and outer circumferential surfaces and fastened to the crimp nut by the outer thread, the part fixed to the bottom plate by crimping is the flange portion, and the inner thread of the double screw nut is the nut portion. According to the above-mentioned configuration, welding of the anchor nut and the bottom plate is not required. Therefore, the fixing nut can be configured by forming a hole at the construction site, attaching the anchor nut to the hole by crimping, and attaching a double screw nut having thread grooves formed on the inner and outer circumferential surfaces. The inner thread of the double screw nut constitutes the above-mentioned nut portion.

[0012] In the mounting structure for the composite panel, the composite panel may include an upper composite panel and a lower composite panel arranged vertically on the base, the upper composite panel includes a lower mounting structure as the mounting structure at a position biased downward from the center in the vertical direction, the lower composite panel includes an upper mounting structure as the mounting structure at a position biased upward from the center in the vertical direction, the lower mounting structure includes a lower connecting member as the mounting member attached to the upper composite panel by tightening the bolt to the nut portion, the lower mounting structure includes an upper connecting member as the mounting member attached to the lower composite panel by tightening the bolt to the nut portion, the lower connecting member and the upper connecting member may be configured to overlap. According to the above configuration, the upper connecting member and the lower connecting member overlap, so that the surfaces of the composite panels arranged adjacent to each other vertically can be arranged flush with each other. In addition, by shifting the relative positions of the lower and upper connecting members, the panels can follow any displacement of the building, allowing the surfaces of adjacent composite panels arranged vertically to remain flush with each other even if the building is displaced.

[0013] In the mounting structure for the composite panel, at least one of the lower connecting member and the upper connecting member may be configured to be larger than the flange protruding from the bottom plate and to have the loose hole through which the bolt is inserted. According to the above configuration, the position of the composite panel can be finely adjusted within the range of the loose hole.

[0014] In the mounting structure of the composite panel, the composite panel includes an upper composite panel and a lower composite panel arranged vertically on the base, the lower composite panel includes an upper mounting structure as the mounting structure at a position biased upward from the center in the vertical direction, the lower composite panel is fixed to the base by a mounting plate as the mounting member, the mounting plate includes a first portion positioned overlapping the upper composite panel and a second portion positioned overlapping the lower composite panel, the first portion is fixed to the base, and the second portion is attached to the lower composite panel by tightening the bolt to the nut portion in the upper mounting structure. According to the above configuration, the composite panel can be mounted to the base by suspending it through the mounting plate. This makes it possible to narrow the fastening space. In addition, the mounting plate can also be displaced following the displacement of the building. This makes it possible to maintain a flush state of the surfaces of the composite panels arranged adjacent to each other vertically even if the building is displaced.

[0015] In the mounting structure of the composite panel, the composite panel includes an upper composite panel and a lower composite panel arranged vertically on the base, the upper composite panel includes a lower mounting structure as the mounting structure at a position biased downward from the center in the vertical direction, and the lower mounting structure may be configured such that the bolt is fastened to the nut portion, so that a connecting plate as the mounting member attached to the upper composite panel extends toward the lower composite panel and contacts the bottom plate of the lower composite panel. According to the above configuration, the connecting plate contacts the bottom plate, so that the composite panels arranged adjacent to each other vertically can be arranged flush. In addition, the connecting plate can be displaced following the displacement of the building. As a result, even if the building is displaced, the surfaces of the composite panels arranged adjacent to each other vertically can be maintained flush.

[0016] The mounting structure for the composite panel may include a stopper that connects the honeycomb panel and the finishing material, the stopper being configured by bending a plate material, and the stopper having a fixing portion that overlaps the bottom plate and is fixed to the honeycomb panel, and an extension portion that extends through the end face of the honeycomb panel to the end face of the finishing material. According to the above configuration, the stopper is disposed so that the extension portion is aligned with the end face (lower surface) of the composite panel. This allows the stopper to prevent the finishing material from shifting downward from the honeycomb panel.

[0017] In the above mounting structure for the composite panel, the finishing material may be configured to have a groove on its end face, and the stopper may be configured to have an engagement portion that engages with the groove. According to the above configuration, the engagement portion of the stopper fixed to the honeycomb panel engages with a groove provided not only on the bottom face of the finishing material but also on the end faces that form the top face and side faces, thereby integrating the honeycomb panel and the finishing material. In other words, it is possible to prevent the composite panel from peeling forward from the base portion. Effect of the Invention

[0018] According to the present invention, the reliability of the mounting structure for mounting a composite panel to a base portion can be improved. [Brief description of the drawings]

[0020] Hereinafter, a mounting structure for a composite panel to which the present invention is applied will be described with reference to the drawings. [First embodiment] [Composite Panel] 1 and 2, the composite panel 1 is to be attached to the wall surface of a structure such as a shopping center, a hotel, a facility entrance, a store, etc. The composite panel 1 is not used on an external wall such as the exterior wall of a building, but is an interior panel to be used on an internal wall such as indoors.

[0021] As shown in FIG. 3, the composite panel 1 includes a finishing material 2 and a honeycomb panel 3 to which the finishing material 2 is fixed. The finishing material 2 is a panel such as a stone panel or a ceramic panel. The stone panel is marble, granite, or the like, which has a higher mass and is heavier than ceramic tiles. In this embodiment, a stone panel is used for the finishing material 2. While a stone panel usually has a stone thickness of about 20 mm to 30 mm, the stone panel used in this embodiment is a thin stone panel, for example, with a stone thickness of about 3 mm to 17 mm, preferably about 6 mm. This reduces the weight of the finishing material 2. For example, the finishing material 2, which is a thin stone panel, is about 70% lighter than a conventional stone panel.

[0022] The honeycomb panel 3 includes a honeycomb core 3a, a top plate 3b, and a bottom plate 3c. The honeycomb core 3a is a structural material having a honeycomb shape, and is made of a lightweight and high-strength metal material, in this embodiment, aluminum foil. The honeycomb shape is preferably hexagonal, but may be a polygonal shape such as a triangle, a rectangle, or an octagon. The honeycomb core 3a includes a top surface, which is a first surface, and a bottom surface, which is a second surface, facing each other. The top plate 3b is fixed to the top surface. The bottom plate 3c is fixed to the bottom surface. The top plate 3b and the bottom plate 3c are made of metal plates, which are aluminum plates, which are the same material as the honeycomb core 3a, in this embodiment.

[0023] The top plate 3b is bonded to the top surface of the honeycomb core 3a by an adhesive. The finishing material 2 and the honeycomb panel 3 have different thermal expansion coefficients. As the adhesive, an adhesive that absorbs the difference in thermal expansion and contraction between the finishing material 2 and the honeycomb panel 3, such as a rubber-based adhesive, is selected. This prevents the composite panel 1 from warping or other deformation caused by the difference in thermal expansion coefficients. Note that deformation caused by the difference in thermal expansion coefficients is absorbed not only by the adhesive but also by the honeycomb panel 3 itself.

[0024] The bottom plate 3c is also bonded to the bottom surface of the honeycomb core 3a with the same adhesive as that used to bond the top plate 3b. In this embodiment, the thickness of the bottom plate 3c is greater than that of the top plate 3b. This allows the metal fittings (anchor nuts 12) constituting the mounting structure 6 to be welded to the bottom plate 3c. The top plate 3b and / or the bottom plate 3c may be integrated with the honeycomb core 3a by welding.

[0025] The composite panel 1 described above uses a thin stone panel as the finishing material 2, and the thin stone panel is fixed to the honeycomb panel 3, thereby realizing a lightweight structure while maintaining high strength. When attaching the composite panel 1 to the base part 9 (see FIG. 8, etc.), a mounting structure can be constructed using metal fittings that are smaller and lighter than conventional ones. Furthermore, because the composite panel 1 is lightweight, it can be used for the base part 9 not only with a steel frame base, but also with a lightweight steel frame base or LGS (Light Gauge Steel) construction.

[0026] As shown in Fig. 1, the composite panel 1 is, for example, a rectangular panel, and is arranged in the vertical direction from the floor to the ceiling and further in the horizontal direction on a base portion 9 provided on a wall surface. As shown in Fig. 2, each composite panel 1 is provided with mounting structures 6 for mounting to the base portion 9 at, for example, four places.

[0027] In the left-right direction of each composite panel 1, the mounting structure 6 is disposed at a position offset to the left or right with respect to a first center line 4a extending vertically through the center in the left-right direction. For example, the mounting structure 6 is disposed at a position about 1 / 4 to 1 / 34, preferably about 1 / 8, of the long side length from each of the left and right short sides.

[0028] In the vertical direction of each composite panel 1, the mounting structure 6 is disposed at a position offset vertically from the second center line 4b extending left and right through the center in the vertical direction. For example, the mounting structure 6 is disposed at a position about 1 / 8 to 1 / 40, preferably about 1 / 16 to 1 / 20 of the short side length from each of the upper and lower long sides.

[0029] In this embodiment, in each composite panel 1, the two upper mounting structures 6 are upper mounting structures 6a, and the two lower mounting structures 6 are lower mounting structures 6b. The two upper mounting structures 6a are arranged in a position that is symmetrical about the first center line 4a, and the two lower mounting structures 6b are also arranged in a position that is symmetrical about the first center line 4a. In addition, in FIG. 2, the two upper and lower mounting structures 6 on the left side and the two upper and lower mounting structures on the right side are arranged in a position that is symmetrical about the second center line 4b. In the following, the upper mounting structure 6a and the lower mounting structure 6b are collectively referred to as the mounting structures 6.

[0030] Furthermore, in each composite panel 1, two stoppers 7 for integrating the finishing material 2 and the honeycomb panel 3 are disposed on each of the upper and lower long sides, for a total of four stoppers 7. The stoppers 7 are disposed on the composite panel 1 at positions closer to the left and right short sides than to the first center line 4a on each of the upper and lower long sides. For example, the stoppers 7 are disposed between each short side and the mounting structure 6 that is positioned closest to the stoppers 7. Each stopper 7 is disposed on each of the upper and lower long sides at a position 1 / 5 to 1 / 48, preferably about 1 / 20 of the long side length from the left and right short sides.

[0031] [Mounting structure] As shown in FIG. 3, the mounting structure 6 includes a hole 11 and an anchor nut 12. The hole 11 is a bottomed hole recessed from the bottom plate 3c side toward the top plate 3b side. For example, the hole 11 is formed by drilling the bottom plate 3c and the honeycomb core 3a with a drill or the like, and the hole 11 is a bottomed hole whose bottom is closed by the top plate 3b. An anchor nut 12 as a fixing nut is disposed in the hole 11.

[0032] The anchor nut 12 includes a nut portion 12a and a flange portion 12b. The nut portion 12a has a cylindrical shape and includes a bolt insertion hole 12c having one end as an open end and the other end closed. The nut portion 12a has an outer diameter that can be fitted into the hole 11. The bolt insertion hole 12c is a bottomed hole with an internal diameter portion of the nut portion 12a and a female thread cut therein.

[0033] The flange portion 12b is configured to project outward from around the open end of the bolt insertion hole 12c, and its outer peripheral end has a larger diameter than the hole 11. The anchor nut 12 is made of a metal material or the like that can be welded to the bottom plate 3c, and in this embodiment, it is formed of aluminum.

[0034] The length L1 from the insertion end of the nut portion 12a of the anchor nut 12 to the back surface of the flange portion 12b (the proximal end of the nut portion 12a) is shorter than the length (depth) L2 from the surface of the bottom plate 3c to the bottom surface of the hole 11 (the back surface of the top plate 3b) (L1 < L2). When the nut portion 12a of the anchor nut 12 is fitted into the hole 11, the flange portion 12b abuts against the surface of the bottom plate 3c. At this time, a gap is provided between the insertion end of the nut portion 12a and the bottom surface 11a of the hole 11, and between the side surface 11b of the hole 11 and the outer peripheral surface of the nut portion 12a. This gap becomes an adhesive space 13a for storing an adhesive 13 for adhering the nut portion 12a in the hole 11. The adhesive space 13a is filled with the adhesive 13.

[0035] The adhesive 13 used in this embodiment is preferably an adhesive capable of high-strength bonding between metals. Furthermore, an acrylic adhesive or the like is used as the adhesive 13. The amount of adhesive 13 is an amount that can bond at least the bottom surface of the hole 11 (the back surface of the top plate 3b) and the insertion end of the nut portion 12a. The amount of adhesive 13 does not necessarily need to be enough to fill the entire bonding space 13a. It is sufficient that the amount is at least enough to bond the bottom surface 11a of the hole 11 and the insertion end surface of the nut portion 12a. If the adhesive 13 overflows onto the surface of the bottom plate 3c, the adhesive 13 will be interposed between the bottom plate 3c and the flange portion 12b, which may result in a decrease in the welding strength between the bottom plate 3c and the flange portion 12b.

[0036] As shown in FIG. 4, the anchor nut 12 adhered to the hole 11 by the adhesive 13 has the outer periphery of the flange 12b welded to the bottom plate 3c. In this embodiment, laser welding is used as an example. The welding position of the welded portion 13b where the outer periphery of the flange 12b and the bottom plate 3c are welded may be the outer periphery end of the flange 12b, i.e., the boundary portion, but is preferably located inside the outer periphery end. The welding is performed inside the outer periphery end, so that the base materials melt and mix more with each other, thereby increasing the welding strength and further improving durability. In the bottom plate 3c of the honeycomb panel 3, the flange 12b protrudes from the surrounding area by the thickness of the flange 12b.

[0037] [Modifications of anchor nuts] The anchor nut 12 can be replaced by a fixing nut consisting of a crimp nut 51 and a double screw nut 52 shown in Figs. 5 to 7. That is, the crimp nut 51 is a molded part made of a metal material such as steel, stainless steel, aluminum, or copper, and includes a sleeve 51a and a flange 51b. In the crimp nut 51, the length L1 from the insertion end of the sleeve 51a to the back surface of the flange 51b (the base end of the sleeve 51a) is the length (depth) L2 from the surface of the bottom plate 3c to the bottom surface of the hole 11 (the back surface of the top plate 3b). The inner surface of the sleeve 51a is threaded to form a nut part 51c. As shown in Fig. 5, the sleeve 51a is fitted into the hole 11. Then, the back surface of the flange 51b abuts against the surface of the bottom plate 3c, and the insertion end of the sleeve 51a abuts against the bottom surface 11a.

[0038] Next, the crimp nut 51 is crimped by a tool such as a nut nut. The nut nut is a tool for attaching the crimp nut 51 to the bottom plate 3c. The crimp nut 51 is crimped around the hole 11 in the bottom plate 3c at the position of the flange 51b on the opposite side to the insertion end of the sleeve 51a. The crimped portion is a crimped portion 51d, which is a flange portion. As a result, the length L1 from the insertion end of the sleeve 51a to the back surface of the flange 51b (the base end of the sleeve 51a) in the crimp nut 51 is shortened, and the insertion end of the sleeve 51a is separated from the bottom surface 11a. The flange 51b protrudes from the bottom plate 3c of the honeycomb panel 3 by the thickness of the flange 51b.

[0039] Next, as shown in FIG. 7, the double screw nut 52 is fastened to the sleeve 51a. The double screw nut 52 includes a cylindrical nut body 52a. The nut body 52a has a cylindrical shape with a through hole on the inside. The nut body 52a has an inner thread 52b on its inner circumferential surface and an outer thread 52c on its outer circumferential surface. The nut body 52a is fastened to the nut part 51c with the adhesive 13 applied to the insertion end or after the adhesive 13 is applied to the inner periphery of the sleeve. That is, the outer thread 52c and the thread of the nut part 51c are fastened in a state in which they are prevented from loosening by the adhesive 13.

[0040] Thus, the fixing nut composed of the crimp nut 51 and the double screw nut 52 is similar to the anchor nut 12. The internal space of the nut body 52a forms the bolt insertion hole 12c. In this modified example, welding to the bottom plate 3c is not required as in the anchor nut 12. Therefore, after the hole 11 is formed at the construction site using a tool such as a drill, the crimp nut 51 is attached to the hole 11. Then, by attaching the double screw nut 52 to the crimp nut 51, it is possible to provide something equivalent to the anchor nut 12.

[0041] Such a modified example using the crimp nut 51 and the double screw nut 52 can be used in combination with the above-mentioned example using the anchor nut 12. For example, a composite panel 1 using the anchor nut 12 may be manufactured in a factory, and a mounting structure using the crimp nut 51 and the double screw nut 52 may be added to increase the mounting strength depending on the conditions at the construction site. In the following explanation, the anchor nut 12 will be used as an example.

[0042] [Installation of composite panels] In Fig. 8, the composite panel 1 located on the upper side is the upper composite panel 1a, and the composite panel 1 located adjacent to the lower side of the upper composite panel 1a is the lower composite panel 1b. In each of the composite panels 1a, 1b arranged vertically, the upper side is fixed to the base portion 9 by an upper mounting structure 6a, and the lower side is connected to the lower composite panel 1b by a lower mounting structure 6b. Fig. 8 shows the lower mounting structure 6b in the upper composite panel 1a and the upper mounting structure 6a in the lower composite panel 1b.

[0043] The upper mounting structure 6a provided on the upper portion of the lower composite panel 1b includes, as mounting members, a first fixing bracket 14 and a second fixing bracket 15. In this embodiment, the base portion 9 is a steel frame base, a light-gauge steel frame base, LGS construction, a concrete base, etc. The mounting structure 6 is a structure that allows the composite panel 1 to be mounted on a light-gauge steel frame base, LGS construction, etc.

[0044] The first fixing metal fitting 14 and the second fixing metal fitting 15 are both, for example, L-shaped metal fittings. The first fixing metal fitting 14 connects the honeycomb panel 3 of the composite panel 1b to the second fixing metal fitting 15. The second fixing metal fitting 15 connects the first fixing metal fitting 14 to the base portion 9.

[0045] The first fixing bracket 14 includes a first piece 14a and a second piece 14b. A smaller bolt 16, such as an M6 bolt, is passed through a through hole in the first piece 14a. The bolt 16 is fastened to the nut portion 12a via the first piece 14a and an upper connecting member 21 described later. The second fixing bracket 15 also includes a first piece 15a and a second piece 15b. The second piece 14b of the first fixing bracket 14 and the first piece 15a of the second fixing bracket 15 are also stacked and fastened by a bolt 17. Furthermore, the second piece 15b of the second fixing bracket 15 is fastened to the base portion 9 by a bolt 18. The bolts 17 and 18 are, for example, drilling tapping screws. As a result, the lower composite panel 1b is attached to the base portion 9 in a hanging manner through the fixing brackets 14 and 15 in the upper mounting structure 6a.

[0046] As shown in FIG. 9, an upper connecting member 21 serving as a mounting member is interposed between the bottom plate 3c and the first piece 14a. The upper connecting member 21 is a rectangular metal plate. The upper connecting member 21 includes a first portion 21a and a second portion 21b in the longitudinal direction. The first portion 21a, which is the lower portion, is interposed between the bottom plate 3c and the first piece 14a and fixed by a bolt 16. The second portion 21b, which is the upper portion of the upper connecting member 21, extends across a joint 19, which is the seam between the upper composite panel 1a and the lower composite panel 1b, and overlaps with the lower composite panel 1b.

[0047] In the lower mounting structure 6b provided in the lower portion of the upper composite panel 1a, a lower connecting member 22 as a mounting member is fastened to the nut portion 12a through the bolt 16. The lower connecting member 22 is a plate material having a rectangular shape, and includes a first portion 22a which is an upper portion, and a second portion 22b which is a lower portion. The first portion 22a is fastened to the nut portion 12a through the bolt 16. The second portion 22b extends in the direction of the lower edge of the lower composite panel 1b, that is, in the direction of the lower composite panel 1b. The second portion 22b here does not straddle the joint 19. The second portion 22b includes a bent portion 22c whose tip is separated from the bottom plate 3c. The second portion 22b sandwiches the second portion 21b of the upper connecting member 21 between the bottom plate 3c and the second portion 22b. When the bolt 16 is fastened, the lower connecting member 22 acts like a leaf spring and presses the upper connecting member 21 against the bottom plate 3c.

[0048] The second portion 21b of the upper connecting member 21 and the second portion 22b of the lower connecting member 22 overlap to adjust the ingress and egress, and the surfaces of the vertically adjacent composite panels 1a, 1b can be arranged flush. Also, the composite panel 1 can be prevented from peeling off into the living space. Furthermore, the relative position of the lower connecting member 22 and the upper connecting member 21 can be shifted to follow the displacement of the building. As a result, even if the building is displaced, the surfaces of the vertically adjacent composite panels 1a, 1b can be maintained flush.

[0049] [Stopper] As shown in FIG. 10, each composite panel 1 is provided with stoppers 7 for preventing the finishing material 2 from falling off the honeycomb panel 3. The stoppers 7 are disposed on both the top and bottom long sides of each composite panel 1. That is, each stopper 7 is disposed near a corner of the rectangular composite panel 1, with a total of four stoppers 7. Each stopper 7 is made of a metal fitting having a hook shape as a whole, and includes a fixing portion 7a, an extension portion 7b, and an engagement portion 7c. The stopper 7 is formed by bending a rectangular metal plate (for example, with a plate thickness of about 1 mm).

[0050] The fixing portion 7a is a piece extending on the bottom plate 3c of the honeycomb panel 3, and is fixed on the bottom plate 3c by fastening the fixing bolt 8a to the honeycomb panel 3. The extending portion 7b is bent at about 90° with respect to the fixing portion 7a, for example. The extending portion 7b extends from the bottom plate 3c side to the top plate 3b side on the end face of the honeycomb panel 3, and its tip extends to the end face of the finishing material 2. The engaging portion 7c is a piece bent at about 90° with respect to the extending portion 7b, and is a piece parallel to the fixing portion 7a. The end face of the finishing material 2 has a groove 8 with which the engaging portion 7c engages, approximately in the middle in the thickness direction. For example, the finishing material 2 has a thickness of 6 mm, and the groove 8 is formed at a position about 3 mm from the exterior surface so that the width is 1 mm.

[0051] The stopper 7 configured as above is arranged with the fixing portion 7a on the bottom plate 3c, the extension portion 7b along the end face of the composite panel 1, and the engagement portion 7c engaged with the groove 8. The fixing portion 7a is then fixed to the honeycomb panel 3 by fastening a fixing bolt 8a, such as a drilling tapping screw. As shown in FIG. 2, each composite panel 1 is arranged near the corners on both sides of the upper and lower long sides. Therefore, the honeycomb panel 3 and the finishing material 2 are also integrated by the stopper 7.

[0052] In the composite panel 1, the finishing material 2 is a thin stone panel, which is lightweight. Therefore, the stopper 7 can also be made of a thinner metal plate, and the groove 8 can be narrowed accordingly. In other words, even if a groove is formed on the end face of the thin stone panel, the groove 8 can be made to have a width that does not cause the thin stone panel to crack.

[0053] [Installation order] The composite panel 1 constructed as above is transported with the anchor nut 12 fixed to the honeycomb panel 3 and the stopper 7 attached. Then, at the construction site, the composite panel 1 is attached to the base 9 by the upper mounting structure 6a so as to be suspended. The lower composite panel 1b is attached to the base 9, and then the upper composite panel 1a is attached to the base 9. At this time, the upper connecting member 21 is inserted between the lower connecting member 22 and the bottom plate 3c. As a result, the upper connecting member 21 is sandwiched between the lower connecting member 22 and the bottom plate 3c. As a result, the inward and outward movement of the composite panel 1 (in a direction intersecting the surface of the composite panel 1 that is the living space side) is adjusted, and the surface of the upper composite panel 1a and the surface of the lower composite panel 1b are made flush with each other. In addition, the composite panel 1 is prevented from peeling off toward the living space. Furthermore, the relative positions of the lower connecting member 22 and the upper connecting member 21 are shifted, so that the composite panel 1 can follow the displacement of the building. This allows the surfaces of the composite panels 1a, 1b adjacent to each other vertically to be kept flush even if the building is displaced.

[0054] [Effects of the first embodiment] The first embodiment as described above can provide the following advantages. (1-1) The composite panel 1 can be made lighter because it is constructed by fixing the finishing material 2 to the honeycomb panel 3. Furthermore, the stone panels that constitute the finishing material 2 are also made thinner, so the finishing material 2 is also made lighter in weight in this respect.

[0055] (1-2) The mounting structure 6 fixes the anchor nut 12 to the hole 11 of the honeycomb panel 3 by bonding and welding. Therefore, for example, it is stronger than when the anchor nut 12 is fixed to the hole 11 by only the adhesive 13. Also, the durability of the relationship between the anchor nut 12 and the honeycomb panel 3 can be improved.

[0056] (1-3) When manufacturing the composite panel 1, the anchor nuts 12 are fixed in the holes 11 with the adhesive 13 before welding. Therefore, it is possible to prevent a decrease in work efficiency caused by the anchor nuts 12 falling off from the holes 11 during the welding work.

[0057] (1-4) The mounting structure 6 for fixing the composite panel 1 to the base portion 9 can also be simplified. For example, since the composite panel 1 is lighter, a bolt with a smaller nominal diameter can be used for the bolt 16 that is fastened to the nut portion 12a of the anchor nut 12 via the mounting member.

[0058] (1-5) The composite panel 1 is lightweight, which makes it easy to transport and attach to the base 9. (1-6) Since the composite panel 1 is lightweight, the structure of the base part 9 and the mounting members can be simplified, so that the space behind the composite panel 1 can be narrowed. This allows the living space and the effective floor area to be increased accordingly.

[0059] (1-7) The composite panel 1 is also excellent in earthquake resistance since each panel is attached to the base 9 via the mounting structure 6. (1-8) The anchor nut 12 is welded to the bottom plate 3c of the honeycomb panel 3 at a position inside the outer circumferential end of the flange portion 12b, thereby making it possible to further increase the welding strength.

[0060] (1-9) By overlapping the upper connecting member 21 and the lower connecting member 22, entry and exit is adjusted, and the surfaces of the vertically adjacent composite panels 1a, 1b can be arranged flush. Also, it is possible to prevent the composite panel 1 from peeling off into the living space. Furthermore, by shifting the relative position of the lower connecting member 22 and the upper connecting member 21, it is possible to follow the displacement of the building. As a result, even if the building is displaced, the surfaces of the vertically adjacent composite panels 1a, 1b can be maintained flush.

[0061] (1-9) The engaging portion 7c of the stopper 7 fixed to the honeycomb panel 3 engages with the groove 8 provided on the end face of the finishing material 2, so that the honeycomb panel 3 and the finishing material 2 can be integrated together.

[0062] [Modification of composite panel installation (Figs. 8 and 9)] As shown in FIG. 11, the base portion 9 is a square steel base material for wall construction, and is configured by inserting square studs 9a into upper and lower runners.

[0063] The upper mounting structure 6a provided on the upper portion of the lower composite panel 1b includes a first fixing bracket 61, a second fixing bracket 62, and a duct channel 63 as mounting members. The first fixing bracket 61 includes a first fixing portion 61a and a second fixing portion 61b. The first fixing portion 61a is a portion fixed to a vertically extending square stud 9a. The first fixing portion 61a has a U-shape, and the square stud 9a is fitted into the first fixing portion 61a. The first fixing portion 61a is fixed to the square stud 9a by a bolt 64 such as an M8 bolt. The second fixing portion 61b is a piece perpendicular to the square stud 9a. The second fixing portion 61b includes a fixing hole whose long axis is the horizontal direction in which the duct channel 63 extends, and the duct channel 63 arranged in the second fixing portion 61b is fixed by a fastening member 65 consisting of a bolt such as an M6 bolt, a nut, or the like.

[0064] The duct channel 63 has a cross-sectional recess shape with a groove formed therein. The duct channel 63 extends, for example, laterally so as to intersect with the corner stud 9a. The duct channel 63 is disposed on the second fixing portion 61b with the groove facing upward, and is fixed by a fastening member 65. The second fixing bracket 62 is fixed to the duct channel 63 by a first metal plate 66a and a second metal plate 66b. The first metal plate 66a is disposed in the groove of the duct channel 63, and the second metal plate 66b is disposed on the groove of the duct channel 63.

[0065] The second fixing metal fitting 62 is, for example, an L-shaped metal fitting. It has a first piece 62a and a second piece 62b. The first piece 62a extends in the vertical direction. The first piece 62a has a loose hole 62c. In the bottom plate 3c of the honeycomb panel 3, the flange 12b protrudes from the surface of the surrounding bottom plate 3c by the thickness of the flange 12b. The loose hole 62c, in which the outer periphery of the flange 12b and the bottom plate 3c are welded, is larger than the protruding part of the flange 12b and has a size that allows the part to escape. That is, the thickness of the first piece 62a is the depth of the loose hole 62c, and the depth of the loose hole 62c is the same as or larger than the protruding height of the flange 12b. The loose hole 62c is an elongated hole with the vertical direction as the long axis. A pressing plate 67 is disposed in the first piece 62a. The first piece 62a is positioned within the flange portion 12b and the loose hole 62c, and a pressing plate 67 is disposed therein. These are then fixed to the nut portion 12a by a bolt 67a such as an M6 bolt. The upper portion of the first piece 62a straddles the joint 19, which is the seam between the upper composite panel 1a and the lower composite panel 1b, and extends so as to overlap with the upper composite panel 1a. The first piece 62a is an upper connecting member.

[0066] The second piece 62b has a fixing hole for fixing to the duct channel 63. The fixing hole is, for example, an elongated hole with the long axis in the front-rear direction. The second piece 62b is then overlapped with the first sheet metal 66a and the second sheet metal 66b, and fixed by a fastening member 68 composed of a bolt such as an M6 bolt, a nut, a nut plate, or the like.

[0067] The lower mounting structure 6b provided on the lower portion of the upper composite panel 1a has a lower connecting member 71 as a mounting member fastened to the nut portion 12a through a bolt 72. The lower connecting member 71 is a plate material having a rectangular shape, and has a first portion 71a which is an upper portion, and a second portion 71b which is a lower portion. The first portion 71a is fastened to the nut portion 12a through the bolt 72. The second portion 71b extends in the direction of the lower edge of the lower composite panel 1b, i.e., in the direction of the lower composite panel 1b. The second portion 71b has a bent portion 71c whose tip is separated from the bottom plate 3c. The bent portion 71c extends above the joint 19.

[0068] A lower plate 73 is disposed on the bottom plate 3c. The lower plate 73 is a rectangular metal plate, and has the same thickness as the first piece 62a, for example. The lower plate 73 has a loose hole 73a. The loose hole 73a is larger than the protruding portion of the flange portion 12b, and has a size that allows the protruding portion to escape. The second portion 71b sandwiches the tip side of the first piece 62a between the bottom plate 3c and the lower plate 73. When the bolt 72 is fastened, the lower connecting member 71 acts like a leaf spring and presses the tip side of the first piece 62a against the bottom plate 3c. The first piece 62a has a loose hole 62c through which the bolt 67a is inserted. Therefore, the position of the composite panel 1 relative to the first piece 62a can be finely adjusted within the range of the loose hole 62c.

[0069] The upper part of the first piece 62a and the second part 71b overlap each other to adjust the ingress and egress, and the surfaces of the composite panels 1a, 1b adjacent to each other vertically can be arranged flush. In addition, the composite panel 1 can be prevented from peeling off toward the living space. Furthermore, the upper part of the first piece 62a and the second part 71b can follow the displacement of the building by shifting their relative positions. This allows the surfaces of the composite panels 1a, 1b adjacent to each other vertically to remain flush even if the building is displaced. In this embodiment, either one of the loose holes 62c, 73a does not have to be a loose hole.

[0070] Second Embodiment 12, in the second embodiment, the composite panel 1 is attached to the base portion 9 in a manner that the composite panel 1 is suspended by the mounting plate 31. In addition, the surface of the upper composite panel 1a and the surface of the lower composite panel 1b are made flush with each other by the connecting plate 41. Both the mounting plate 31 and the connecting plate 41 are attached to the composite panel 1 via the mounting structure 6.

[0071] The mounting plates 31 are disposed on both sides of the upper long side of the composite panel 1. The connecting plates 41 are disposed on both sides of the lower long side of the composite panel 1. For example, on the upper long side, they are disposed at a position about 1 / 4 to 1 / 34, preferably about 1 / 8, of the long side length from each of the left and right short sides. The connecting plates 41 are disposed so as to be lined up on the inside of the mounting plates 31.

[0072] 13, the second portion 31b of the mounting plate 31 is fixed to both sides of the upper long side of the lower composite panel 1b by the mounting structure 6a. The mounting plate 31 extends upward from the mounting structure 6a. The first portion 31a, which is the upper portion, is fixed to the base portion 9 at a position overlapping the lower portion of the upper composite panel 1a.

[0073] The mounting plate 31 is a metal plate having a rectangular shape. The second portion 31b, which is the lower portion, is fastened to the nut portion 12a constituting the upper mounting structure 6a of the lower composite panel 1b through a bolt 16, such as an M6 bolt, which is smaller than the conventional bolt. In the second embodiment, the mounting plate 31 is attached to the base portion 9, so that the space behind the composite panel 1 is narrower than in the first embodiment. Therefore, a low head bolt or an extremely low head bolt is used for the bolt 16. The first portion 31a of the mounting plate 31 extends to the lower portion of the upper composite panel 1a. The first portion 31a is connected to the plate of the base portion 9 through a fixing bolt 32, such as a drilling tapping screw. That is, the lower composite panel 1b is attached by the mounting plate 31 so as to be hung from a position where it overlaps with the upper composite panel 1a, straddling the joint 19. In the mounting plate 31, the first portion 31a contacts the base portion 9, and the second portion 31b contacts the bottom plate 3c of the honeycomb panel 3. Between the first portion 31a and the second portion 31b is an inclined portion 31c. The inclined portion 31c is also a displacement portion, and when a load is applied in the inward / outward direction, the second portion 31b is displaced toward the base portion 9, thereby absorbing the shock applied to the composite panel 1 together with the adhesive 42. Furthermore, the mounting plate 31 can also be displaced in response to the displacement of the building. As a result, even if the building is displaced, the surfaces of the composite panels 1a, 1b adjacent to each other vertically can be maintained in a flush state.

[0074] The connecting plate 41 is a metal plate having a rectangular shape. The connecting plate 41 is arranged side by side on the inside of the mounting plate 31. In the example of FIG. 14, the first part 41a, which is the upper part, is fastened to the nut part 12a constituting the lower mounting structure 6b of the upper composite panel 1a. The second part 41b, which is the lower part of the connecting plate 41, extends to the upper part of the lower composite panel 1b. The upper and lower composite panels 1a, 1b are fixed to the base part 9 together with the connecting plate 41 by the adhesive 42. The adhesive 42 used in this embodiment is, for example, an elastic adhesive, a rubber-based adhesive, or the like. As an example, the composite panels 1a, 1b are pasted together around the connecting plate 41.

[0075] The first portion 41a of the connecting plate 41 is attached to the lower mounting structure 6b of the upper composite panel 1a. Specifically, the first portion 41a is fastened to the nut portion 12a constituting the lower mounting structure 6b of the upper composite panel 1a. The second portion 41b is bonded and fixed to the base portion 9 and the bottom plate 3c of the upper and lower composite panels 1a and 1b by the adhesive 42. The second portion 41b is in contact with the bottom plate 3c of the lower composite panel 1b. This allows the inward and outward direction to be adjusted, and the surfaces of the composite panels 1a and 1b adjacent to each other vertically to be arranged flush. In addition, the composite panel 1 can be prevented from peeling off toward the living space. Furthermore, the adhesive 42 can absorb impacts applied to the composite panel 1. Furthermore, the connecting plate 41 can also be displaced following the displacement of the building. This allows the surfaces of the composite panels 1a and 1b adjacent to each other vertically to be kept flush even if the building is displaced.

[0076] In the second embodiment, each composite panel 1 is provided with a stopper 7, similarly to the first embodiment. [Effects of the second embodiment] The second embodiment as described above can achieve the effects listed below in addition to the effects (1-1) to (1-7) of the first embodiment.

[0077] (2-1) The composite panel 1 can be attached to the base portion 9 by suspending it through the mounting plate 31. This allows the fastening space to be narrowed. Also, the inclined portion 31c can absorb impacts applied to the composite panel 1. Furthermore, the mounting plate 31 can also be displaced in response to the displacement of the building. This allows the surfaces of the vertically adjacent composite panels 1a, 1b to be kept flush with each other even if the building is displaced.

[0078] (2-2) The connecting plate 41 is attached to the lower mounting structure 6b of the upper composite panel 1a with the first portion 41a, and is fixed to the base portion 9 with the adhesive 42 with the second portion 41b in contact with the bottom plate 3c. This allows the surfaces of the composite panels 1a, 1b adjacent to each other vertically to be arranged flush with each other when the connecting plate 41 is installed. This also prevents the composite panel 1 from peeling off toward the living space. Furthermore, the adhesive 42 can absorb impacts applied to the composite panel 1. Furthermore, the connecting plate 41 can also be displaced following the displacement of the building. This allows the surfaces of the composite panels 1a, 1b adjacent to each other vertically to be kept flush with each other even if the building is displaced.

[0079] [Modification of FIG. 14] As shown in Fig. 15, the upper connecting member 81 provided on the upper portion of the lower composite panel 1b has a first portion 81a and a second portion 81b in the longitudinal direction. The first portion 81a, which is the lower portion, has a through hole 82. A pressing plate 83 is disposed in the first portion 81a. The pressing plate 83 is overlapped on the first portion 81a and fixed to the nut portion 12a by a bolt 84. The second portion 81b, which is the upper portion, straddles the joint 19, which is the seam between the upper composite panel 1a and the lower composite panel 1b, and extends so as to overlap with the upper composite panel 1a.

[0080] A lower connecting member 86 provided on a lower portion of the upper composite panel 1a is fastened to the nut portion 12a through a bolt 87. The lower connecting member 86 is a plate material having a rectangular shape, and includes a first portion 86a which is an upper portion, and a second portion 86b which is a lower portion. The first portion 86a is fastened to the nut portion 12a through the bolt 87. The second portion 86b extends in the direction of the lower edge of the lower composite panel 1b, i.e., in the direction of the lower composite panel 1b. The second portion 86b includes a bent portion 86c whose tip is separated from the bottom plate 3c. The bent portion 86c extends above the joint 19.

[0081] A lower plate 88 is disposed on the bottom plate 3c. The lower plate 88 is a rectangular metal plate and has, for example, the same thickness as the upper connecting member 81. The lower connecting member 86 sandwiches the second portion 81b of the upper connecting member 81 between the bottom plate 3c and the lower plate 88. When the bolt 87 is fastened, the lower connecting member 86 acts like a leaf spring and presses the second portion 81b against the bottom plate 3c.

[0082] The second part 81b and the second part 86b overlap each other to adjust the entrance and exit, and the surfaces of the composite panels 1a and 1b adjacent to each other vertically can be arranged flush. In addition, the composite panel 1 can be prevented from peeling off toward the living space. Furthermore, the second part 81b and the second part 86b can follow the displacement of the building by shifting their relative positions. As a result, even if the building is displaced, the surfaces of the composite panels 1a and 1b adjacent to each other vertically can be maintained flush.

[0083] [Modifications of the stopper] As shown in FIG. 16, the stopper 91 includes a fixing portion 91a and an extending portion 91b. The stopper 91 is formed by bending a rectangular metal plate (for example, about 1 mm thick). The fixing portion 91a is a piece extending on the bottom plate 3c of the honeycomb panel 3, and is fixed on the bottom plate 3c by fastening a fixing bolt 8a to the honeycomb panel 3. The extending portion 91b is formed by bending, for example, about 90° with respect to the fixing portion 91a. The extending portion 91b extends from the bottom plate 3c side to the top plate 3b side on the end face (lower surface) of the honeycomb panel 3, and its tip extends to the end face of the finishing material 2. In this example, the engaging portion 7c as shown in the stopper 7 in FIG. 10 is not provided.

[0084] 17, the stopper 91 configured as above has the fixing portion 91a disposed on the bottom plate 3c, and the extending portion 91b aligned with the end face (lower surface) of the composite panel 1. The fixing portion 91a is then fixed by fastening a fixing bolt 8a, such as a drilling tapping screw, to the honeycomb panel 3. In other words, unlike the stopper 7, the stopper 91 is not disposed on the end faces that form the upper and side surfaces of the composite panel 1. The stopper 91 is a member that prevents the finishing material 2 from shifting downward from the honeycomb panel 3.

[0085] The above first and second embodiments can also be modified as necessary as follows. [Modification of the stopper (see FIG. 10)] In the first and second embodiments, the positions where the stoppers 7 are provided and the number of the stoppers 7 are not limited to the above examples. That is, in addition to or instead of the arrangement in the first and second embodiments, the stoppers 7 may be arranged as follows. For example, the stoppers 7 may be provided on both the top and bottom of the left and right short sides of the composite panel 1. Also, one stopper may be provided at the center of the top and bottom long sides, and one stopper may be provided at the center of the left and right short sides. Furthermore, the stoppers 7 may only be provided on both sides of the upper long side, or only on both sides of the lower long side.

[0086] [Modification of the second embodiment (see FIG. 14)] In the second embodiment, the adhesive 42 may be omitted. Even with such a configuration, the function of preventing the composite panel 1 from peeling off into the living space is lost, but the surfaces of the composite panels 1a, 1b adjacent to each other vertically can be arranged flush with each other.

[0087] [Modifications of the connecting plate] In the second embodiment, the adhesive 42 may be applied not only to the periphery of the connecting plate 41 but also over a wider area, for example, over the entire surface of the composite panels 1a and 1b.

[0088] The connecting plates 41 may be arranged on the outside of the mounting plate 31, or may be arranged spaced apart from the mounting plate 31, instead of being arranged side by side on the inside of the mounting plate 31.

[0089] The connecting plate 41 may be disposed not only at two positions on both sides of the lower long side of the upper composite panel 1a, but also at one or more positions between them. In this case, the mounting structure 6 is provided at the position where the connecting plate 41 is disposed.

[0090] In the second embodiment, the connecting plate 41 may be omitted. Also, the connecting plate 41 may be added to the structure of the first embodiment. In the second embodiment, the first portion 31a of the mounting plate 31 may be arranged so that the entire mounting plate 31 overlaps the lower composite panel 1b, rather than overlapping the upper composite panel 1a. In this case, the position of the upper mounting structure 6a may be lowered so that the first portion 31a also overlaps the lower composite panel 1b.

[0091] [Modifications of the mounting plate (see Figs. 12 and 13)] The mounting plate 31 may be disposed not only in two positions on both sides of the upper long side of the lower composite panel 1b, but also in one or more positions between them. In this case, the mounting structure 6 is provided at the position where the mounting plate 31 is disposed. In other words, the number of mounting plates 31 and mounting structures 6 is not particularly limited, and may be one, or three or more.

[0092] [Modification of the first embodiment] [Modifications of the upper and lower connecting members (see Figure 8)] The upper connecting member 21 may be configured to sandwich the lower connecting member 22 between the bottom plate 3c. This configuration also allows the surface of the upper composite panel 1a to be flush with the surface of the lower composite panel 1b. Also, it is possible to prevent the composite panel 1 from peeling off into the living space.

[0093] The structure for attaching the composite panel 1 to the base part 9 using the fastening metal fittings 14, 15 may be provided not only at two locations on both sides of the upper long side of the lower composite panel 1b, but also at more than two locations. For example, in addition to the two locations on both sides of the upper long side of the lower composite panel 1b, one or more fastenings may be added between them (see FIG. 2).

[0094] The upper connecting member 21 may be attached to a new upper mounting structure 6a using bolts, which is provided separately from the upper mounting structure 6a to which the fixing bracket 14 is attached. In this case, the lower mounting structure 6b of the upper composite panel 1a is provided at a position corresponding to the new mounting structure 6a.

[0095] [Modifications common to the first and second embodiments] In the first and second embodiments, the flange portion 12b and the bottom plate 3c may be welded to each other at the outer circumferential edge, that is, at the boundary portion, as long as the necessary strength is obtained (see FIG. 4).

[0096] If the required strength can be obtained at the welded portion 13b, the adhesive 13 may be omitted. Also, if the decrease in work efficiency during welding can be suppressed by other means, the adhesive 13 may be omitted (see FIG. 3).

[0097] In the first and second embodiments, the hole 11 needs to be a bottomed hole, but the bottom surface 11a may be the back surface of the finishing material 2 instead of the top plate 3b. Also, the hole 11 may extend into the finishing material 2, with the bottom surface 11a being located in the middle in the thickness direction of the finishing material 2. In other words, it is sufficient that the insertion end of the bolt 16 does not face the surface of the finishing material 2.

[0098] In the first and second embodiments, as long as the flange portion 12b of the anchor nut 12 and the bottom plate 3c of the honeycomb panel 3 can be welded to each other, there is no particular limitation on the material. For example, the honeycomb core 3a may be made of aluminum, and the top plate 3b and / or the bottom plate 3c may be made of resin plates such as FRP (Fiber Reinforced Plastics).

[0099] In the first and second embodiments, the shape of the finishing material 2 is not limited to a rectangular shape, and may be a polygonal panel such as a triangle, pentagon, or hexagon, or may be a circular or elliptical panel. Not only may composite panels 1 of the same shape be arranged on the base part 9, but composite panels 1 of various shapes may be attached to the base part 9. The shape of the composite panel 1 depends on the design of the installation location.

[0100] The composite panel 1 may be an exterior wall panel used as an exterior wall such as the exterior wall of a building. According to the above embodiment and its modified examples, the following technical ideas can be derived. (Appendix 1) A composite panel mounting structure in which a composite panel having a finishing material fixed to one surface of a honeycomb panel is fixed to a base portion, The composite panel includes an upper composite panel and a lower composite panel that are arranged vertically on the base portion, The mounting structure includes: A lower mounting structure is provided in the upper composite panel at a position offset downward from the center in the vertical direction, and an upper mounting structure is provided in the lower composite panel at a position offset upward from the center in the vertical direction, A lower connecting member extends from the lower mounting structure toward the upper mounting structure, an upper connecting member extends from the upper mounting structure toward the lower mounting structure; The lower connecting member and the upper connecting member are configured to overlap each other. Mounting structure for composite panels.

[0101] In the mounting structure of a composite panel, it is desired to improve the efficiency of mounting the composite panel to the base. According to the above-mentioned configuration, the honeycomb panel and one of the lower and upper connecting members are sandwiched between the other connecting member. This makes it possible to easily mount the composite panels arranged adjacent to each other vertically so that their surfaces are flush with each other.

[0102] (Appendix 2) A stopper structure for connecting a honeycomb panel and a finishing material fixed to one surface of the honeycomb panel by an adhesive, comprising: The finish has a groove on an end surface, a fixing portion that overlaps the other surface of the honeycomb panel and is fixed to the honeycomb panel, and an extension portion that extends through the end surface of the honeycomb panel to the end surface of the finishing material. Stopper structure.

[0103] A composite panel in which a finishing material is fixed to one surface of a honeycomb panel can achieve weight reduction while maintaining the strength of the composite panel. However, the finishing material and one surface of the honeycomb panel are often bonded and fixed with an adhesive. It is desired to prevent the finishing material from falling off the honeycomb panel and to further improve the reliability of the composite panel.

[0104] According to the above-mentioned configuration, the stopper is disposed so that the extension portion is aligned along the end face (lower face) of the composite panel, thereby making it possible for the stopper to prevent the finishing material from shifting downward from the honeycomb panel.

[0105] (Appendix 3) The finishing material has a groove on an end surface, and the stopper has an engagement portion that engages with the groove. 2. A mounting structure for a composite panel as described in (Appendix 3).

[0106] According to the above configuration, the engagement portion of the stopper fixed to the honeycomb panel engages with the grooves provided on the end faces constituting not only the lower surface of the finishing material but also the upper surface and side surfaces, thereby integrating the honeycomb panel and the finishing material. In other words, it is possible to prevent the composite panel from peeling forward from the base portion. In addition, it is possible to further improve reliability. [Explanation of symbols]
