Description

[Technical Field]

[0001] The present invention relates to a composite panel mounting structure for fixing a composite panel, which has a finishing material fixed to one surface of a honeycomb panel, to a base portion. [Background technology]

[0002] Regarding mounting structures for fixing exterior materials such as stone or ceramic to the framework wall of a building, Patent Document 1 and other publications describe composite panels in which the exterior material is adhesively fixed to one side of a honeycomb panel. Such composite panels are fixed to a substrate using various mounting structures. Patent Document 1 and other publications describe drilling holes in the honeycomb panel, inserting studs with threads on the outer periphery into the holes, and fixing the studs with a curable resin or adhesive. Then, studs are inserted into mounting holes for fastening hardware to connect the honeycomb panel to the substrate, and nuts are then tightened onto the studs. In this way, the fastening hardware is fixed to the honeycomb panel. The use of honeycomb panels allows composite panels to be both strong and lightweight. This facilitates the process of fixing the composite panel to the substrate, resulting in excellent workability. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2007-40395 Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, the mounting structure of such a composite panel to the base is as follows: There is a need to narrow the fastening space behind the composite panel. [Means for solving the problem]

[0005] The mounting structure for a composite panel that solves the above-mentioned problems is a mounting structure for fixing a composite panel, which is made of a honeycomb panel and has a finishing material fixed to one surface thereof, to a base portion, wherein the composite panel comprises an upper composite panel and a lower composite panel that are arranged vertically on the base portion, and the mounting structure comprises a first lower mounting structure provided on the upper composite panel at a position offset downward from the center in the vertical direction, and a first upper mounting structure provided on the lower composite panel at a position offset upward from the center in the vertical direction, the lower composite panel being fixed to the base portion by a mounting plate, and the mounting plate comprises a first portion positioned overlapping the upper composite panel and a second portion positioned overlapping the lower composite panel, the first portion being fixed to the base portion, and the second portion being fixed to the lower composite panel by the first upper mounting structure. In the above mounting structure for a composite panel, it is preferable that an inclined portion displaceable in an inward / outward direction is provided between the first portion and the second portion. In the mounting structure for the above-mentioned composite panels, the mounting structure further includes a second lower mounting structure provided on the upper composite panel at a position offset downward from the center in the vertical direction, and a second upper mounting structure provided on the lower composite panel at a position offset upward from the center in the vertical direction, and it is preferable that a lower connecting member fixed to the upper composite panel extends from the second lower mounting structure in the direction of the second upper mounting structure, and that an upper connecting member fixed to the lower composite panel extends from the second upper mounting structure in the direction of the second lower mounting structure, and that the lower connecting member and the upper connecting member are overlapped. In the above-mentioned composite panel mounting structure, it is preferable that a flange portion protruding from one end of a nut portion inserted into a non-through hole formed from the bottom plate side of the honeycomb panel is arranged around the hole in the bottom plate, and that at least one of the lower connecting member and the upper connecting member has a loose hole larger than the flange portion protruding onto the bottom plate. It is preferable that the above-mentioned composite panel mounting structure further includes a stopper that connects the honeycomb panel and the finishing material, the stopper being formed by bending a plate material, and the stopper having a fixing portion that overlaps the bottom plate of the honeycomb panel 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. In the above-described mounting structure for a composite panel, it is preferable that the finishing material has a groove on an end surface, and the stopper has an engaging portion that engages with the groove. The mounting structure for a composite panel that solves the above-mentioned problems is a mounting structure for fixing a composite panel, which is made 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 the top surface of the honeycomb core, and a bottom plate fixed to the bottom surface of the honeycomb core, the finishing material being fixed to the top plate, the mounting structure comprising: a hole formed 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, the nut portion being disposed in the hole and the flange portion being 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 an intervening mounting member for connecting to the base portion.

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

[0007] Because 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 to the base, making it possible to narrow the space behind the composite panel. This in turn allows for a larger living space and a larger effective floor area.

[0008] In the above-described composite panel mounting structure, the nut portion may be configured to be fixed in the hole with an adhesive. With this configuration, the fixing nut is fixed to the hole not only by welding but also by the adhesive strength of the adhesive. Therefore, the mounting strength of the fixing nut to the honeycomb panel can be further increased.

[0009] In the above-described mounting structure for a composite panel, the flange may be positioned 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, thereby providing a stronger fixation than when using adhesive alone. During construction, the composite panel is handled as a single unit with the fixing nut in place. Therefore, at the construction site, the only work required is to fix the composite panel to the base via the mounting member. This simplifies and facilitates the construction process, improving work efficiency.

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

[0011] In the above-described composite panel mounting structure, 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 its inner and outer peripheral surfaces and fastened to the crimp nut by the outer threads, wherein the portion fixed to the bottom plate by crimping is the flange portion, and the inner threads of the double-screw nut are the nut portion. This configuration eliminates the need for welding the anchor nut to the bottom plate. Therefore, the fixing nut can be constructed by drilling a hole at the construction site, attaching the anchor nut to the hole by crimping, and then attaching a double-screw nut with thread grooves formed on its inner and outer peripheral surfaces. The inner threads of the double-screw nut constitute the nut portion.

[0012] In the mounting structure for composite panels, the composite panels may include an upper composite panel and a lower composite panel arranged vertically on the base portion, the upper composite panel having a lower mounting structure as the mounting structure at a position offset downward from the center in the vertical direction, the lower composite panel having an upper mounting structure as the mounting structure at a position offset upward from the center in the vertical direction, the lower mounting structure having 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 having 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 overlapping each other. According to the above configuration, the overlapping of the upper connecting member and the lower connecting member allows the surfaces of the vertically adjacent composite panels to be arranged flush with each other. Furthermore, 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 lined up vertically to remain flush even if the building is displaced.

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

[0014] In the mounting structure for composite panels, the composite panels may be arranged vertically on the base, thereby comprising an upper composite panel and a lower composite panel aligned vertically. The lower composite panel may include an upper mounting structure as the mounting structure, positioned above the center in the vertical direction. The lower composite panel may be fixed to the base by a mounting plate as the mounting member. The mounting plate may include a first portion overlapping the upper composite panel and a second portion 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 attached to the base by suspending it via the mounting plate. This allows for a narrower fastening space. Furthermore, the mounting plate can also be displaced in response to the displacement of the building. This allows for the surfaces of adjacent composite panels aligned vertically to remain flush with each other, even if the building displaces.

[0015] In the above-described mounting structure for composite panels, the composite panels may be arranged vertically on the base portion, thereby comprising an upper composite panel and a lower composite panel aligned vertically, the upper composite panel including a lower mounting structure positioned downward from the vertical center, and the lower mounting structure may be configured such that, when the bolts are tightened to the nuts, a connecting plate serving 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-described configuration, the connecting plate contacts the bottom plate, thereby allowing the vertically adjacent composite panels to be positioned flush with each other. Furthermore, the connecting plate can also be displaced in response to displacement of the building. This allows the surfaces of the vertically adjacent composite panels to remain flush with each other even if the building is displaced.

[0016] The above-mentioned composite panel mounting structure may also include a stopper that connects the honeycomb panel and the finishing material, the stopper being formed 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 this configuration, the stopper is positioned so that the extension portion fits along 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-described composite panel mounting structure, the finishing material may have a groove on its end face, and the stopper may have an engaging portion that engages with the groove. According to this configuration, the engaging portion of the stopper fixed to the honeycomb panel engages with a groove provided on not only the bottom face of the finishing material but also the end face that constitutes the top face and side face, thereby integrating the honeycomb panel and the finishing material. This prevents the composite panel from peeling forward from the base. [Effects of the Invention]

[0018] According to the present invention, The fastening space behind the composite panel can be narrowed. [Brief explanation of the drawings]

[0020] A mounting structure for a composite panel to which the present invention is applied will be described below with reference to the drawings. [First embodiment] [Composite panel] 1 and 2, the composite panel 1 is 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 exterior wall such as the outer wall of a building, but is an interior panel used on an interior 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 ceramic panel. Stone panels are made of marble, granite, or other materials that are heavier and have a greater mass than ceramic tiles. In this embodiment, a stone panel is used as the finishing material 2. While stone panels typically have a stone thickness of approximately 20 mm to 30 mm, the stone panel used in this embodiment is a thin stone panel, with a stone thickness of, for example, approximately 3 mm to 17 mm, preferably approximately 6 mm. This reduces the weight of the finishing material 2. For example, the finishing material 2, which is a thin stone panel, is approximately 70% lighter than conventional stone panels.

[0022] The honeycomb panel 3 comprises 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, high-strength metal material, in this embodiment, aluminum foil. The honeycomb shape is preferably hexagonal, but may be a polygonal shape such as triangular, rectangular, or octagonal. The honeycomb core 3a comprises 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 in this embodiment are aluminum plates, the same material as the honeycomb core 3a.

[0023] The top plate 3b is bonded to the top surface of the honeycomb core 3a with an adhesive. The finishing material 2 and the honeycomb panel 3 have different thermal expansion coefficients. An adhesive that can absorb 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 as the adhesive. This prevents deformation such as warping of the composite panel 1 due to the difference in thermal expansion coefficients. Note that deformation due to 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 adhered to the bottom surface of the honeycomb core 3a with the same adhesive as that used to adhere the top plate 3b. In this embodiment, the thickness of the bottom plate 3c is greater than the thickness of the top plate 3b. This makes it possible to weld the metal fittings (anchor nuts 12) that constitute the mounting structure 6 to the bottom plate 3c. The top plate 3b and / or bottom plate 3c may be integrated with the honeycomb core 3a by welding.

[0025] The composite panel 1 described above uses thin stone panels as the finishing material 2 and fixes the thin stone panels to the honeycomb panel 3, thereby achieving high strength yet lightweight construction. When attaching the composite panel 1 to the base 9 (see Figure 8, etc.), a mounting structure can be constructed using metal fittings that are smaller and lighter than conventional ones. Furthermore, the lightweight composite panel 1 makes it possible to use lightweight steel bases or LGS (Light Gauge Steel) construction for the base 9 in addition to steel bases.

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

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

[0028] The mounting structure 6 is disposed at a position offset up or down from the second center line 4b that extends left and right through the center in the up-down direction of each composite panel 1. For example, the mounting structure 6 is disposed at a position inward from each of the upper and lower long sides by about 1 / 8 to 1 / 40, preferably about 1 / 16 to 1 / 20 of the length of the short side.

[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 positions that are symmetrical about the first center line 4a, and the two lower mounting structures 6b are also arranged in positions that are 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 6 on the right side are arranged in positions that are symmetrical about the second center line 4b. Note that hereinafter, the upper mounting structures 6a and the lower mounting structures 6b are collectively referred to as the mounting structures 6.

[0030] Furthermore, each composite panel 1 has stoppers 7 for integrating the finishing material 2 and the honeycomb panel 3, two on each of the upper and lower long sides, for a total of four. The stoppers 7 are arranged 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, they are arranged between each short side and the mounting structure 6 that is closest to the stopper 7. Each stopper 7 is arranged on each of the upper and lower long sides at a distance of 1 / 5 to 1 / 48, preferably about 1 / 20, of the long side length from the left and right short side.

[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 serving as a fixing nut is placed 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, one end of which is open, and the other end of which is closed, and includes a bolt insertion hole 12c. The nut portion 12a has an outer diameter that allows it to fit into the hole 11. The bolt insertion hole 12c is the inner diameter portion of the nut portion 12a, and is a bottomed hole with an internal thread.

[0033] The flange 12b is configured to protrude outward from the periphery of the open end of the bolt insertion hole 12c, and its outer peripheral edge 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 made 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 base 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] As the adhesive 13 used in this embodiment, an adhesive capable of high-strength adhesion between metals is preferable. Further, as the adhesive 13, an acrylic adhesive or the like is used. Also, the amount of the adhesive 13 is an amount that enables adhesion between 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. It is not always necessary for the adhesive 13 to fill the entire adhesive space 13a. It is sufficient if the amount is at least such that the bottom surface 11a of the hole 11 and the insertion end surface of the nut portion 12a can be adhered. If the adhesive 13 overflows to the surface of the bottom plate 3c, the adhesive 13 will be interposed between the bottom plate 3c and the flange portion 12b, and as a result, the welding strength between the bottom plate 3c and the flange portion 12b may be reduced.

[0036] As shown in FIG. 4, the anchor nut 12 adhered to the hole 11 with the adhesive 13 has the outer peripheral portion of the flange portion 12b and the bottom plate 3c welded. In this embodiment, as an example, laser welding is performed. The welding position of the welded portion 13b where the outer peripheral portion of the flange portion 12b and the bottom plate 3c are welded may be the outer peripheral end of the flange portion 12b, that is, the boundary portion, but it is preferably at a position inside the outer peripheral end. Welding performed inside the outer peripheral end can increase the welding strength and further improve the durability by melting and mixing more of the base materials together. In the bottom plate 3c of the honeycomb panel 3, the flange portion 12b protrudes by the thickness of the flange portion 12b more than the surroundings.

[0037] 〔Modified Example of Anchor Nut〕 The anchor nut 12 can be replaced with a fixing nut consisting of a crimped nut 51 and a double screw nut 52 shown in FIGS. 5 to 7. Specifically, the crimped 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 crimped 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 same as 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 portion 51c. As shown in FIG. 5, the sleeve 51a is fitted into the hole 11. Then, the back surface of the flange 51b butts against the surface of the bottom plate 3c, and the insertion end of the sleeve 51a butts against the bottom surface 11a.

[0038] Next, the crimping nut 51 is crimped using a tool such as a crimping tool. The crimping tool is used to attach the crimping nut 51 to the bottom plate 3c. The crimping nut 51 is crimped around the hole 11 in the bottom plate 3c at the position of the flange 51b, opposite the insertion end of the sleeve 51a. The crimped portion is the crimped portion 51d, which is the 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) of the crimping nut 51 is shortened, and the insertion end of the sleeve 51a is spaced apart 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, a 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 portion 51c with adhesive 13 applied to the insertion end or after adhesive 13 is applied to the inner periphery of the sleeve. That is, the nut is fastened in a state in which the outer thread 52c and the thread of the nut portion 51c 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 is the case with 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, something equivalent to the anchor nut 12 can be provided.

[0041] Such a modified example using the crimp nut 51 and the double screw nut 52 can also be used in combination with the example using the anchor nut 12 described above. For example, a composite panel 1 using the anchor nut 12 may be manufactured in a factory, and then an attachment structure using the crimp nut 51 and the double screw nut 52 may be added to increase the attachment 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 on the lower side of the upper composite panel 1a is the lower composite panel 1b. In each of the composite panels 1a and 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 for the upper composite panel 1a and the upper mounting structure 6a for 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 fittings 14 and the second fixing metal fittings 15 are both, for example, L-shaped metal fittings. The first fixing metal fittings 14 connect the honeycomb panel 3 of the composite panel 1b to the second fixing metal fittings 15. The second fixing metal fittings 15 connect the first fixing metal fittings 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 inserted through a through hole in the first piece 14a. The bolt 16 is then 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 overlapped and fastened together by a bolt 17. The second piece 15b of the second fixing bracket 15 is further 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 via 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 an attachment 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, straddles a joint 19, which is the seam between the upper composite panel 1a and the lower composite panel 1b, and extends so as to overlap the lower composite panel 1b.

[0047] In the lower mounting structure 6b provided on the lower portion of the upper composite panel 1a, a lower connecting member 22 serving as a mounting member is fastened to a nut portion 12a via a bolt 16. The lower connecting member 22 is a rectangular plate material 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 via the bolt 16. The second portion 22b extends toward the lower edge of the lower composite panel 1b, i.e., toward the lower composite panel 1b. Here, the second portion 22b does not straddle the joint 19. The second portion 22b includes a bent portion 22c whose tip is spaced apart 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 bolts 16 are 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 for movement in and out, allowing the surfaces of the vertically adjacent composite panels 1a, 1b to be arranged flush. This also prevents the composite panel 1 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 accommodate displacement of the building. This allows the surfaces of the vertically adjacent composite panels 1a, 1b to remain flush, even if the building is displaced.

[0049] [Stopper] As shown in FIG. 10, each composite panel 1 is provided with stoppers 7 that prevent the finishing material 2 from falling off the honeycomb panel 3. The stoppers 7 are arranged on both the top and bottom long sides of each composite panel 1. That is, each stopper 7 is arranged 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 extending portion 7b, and an engaging portion 7c. The stopper 7 is made by bending a rectangular metal plate (for example, with a thickness of about 1 mm).

[0050] The fixing portion 7a is a piece extending above the bottom plate 3c of the honeycomb panel 3 and is fixed to the bottom plate 3c by tightening a fixing bolt 8a to the honeycomb panel 3. The extending portion 7b is bent at an angle of approximately 90° relative to the fixing portion 7a. The extending portion 7b extends from the bottom plate 3c toward the top plate 3b on the end face of the honeycomb panel 3, with its tip extending to the end face of the finishing material 2. The engaging portion 7c is a piece bent at an angle of approximately 90° relative to the extending portion 7b and is parallel to the fixing portion 7a. The end face of the finishing material 2 has a groove 8 approximately halfway along its thickness that engages with the engaging portion 7c. For example, if the finishing material 2 is 6 mm thick, the groove 8 is formed to be 1 mm wide and located approximately 3 mm from the exterior surface.

[0051] The stopper 7 configured as described above has its fixing portion 7a placed on the bottom plate 3c, its extension portion 7b aligned with the end face of the composite panel 1, and its engagement portion 7c engaged in the groove 8. The fixing portion 7a is then fixed to the honeycomb panel 3 by tightening fixing bolts 8a, such as drilling and tapping screws, to the honeycomb panel 3. As shown in Figure 2, each composite panel 1 is placed near the corners on both the top and bottom 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 lightweight thin stone panel. Therefore, the stopper 7 can also be made of a thinner metal plate, and the groove 8 can also 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 be wide enough so that the thin stone panel will not crack.

[0053] [Installation order] The composite panel 1 configured as described above is transported with the anchor nuts 12 fixed to the honeycomb panels 3 and the stoppers 7 attached. At the construction site, the composite panel 1 is attached to the base 9 by the upper mounting structure 6a, suspended from the base 9. The lower composite panel 1b is attached to the base 9 first, followed by the upper composite panel 1a. At this time, the upper connecting member 21 is inserted between the lower connecting member 22 and the bottom plate 3c. This sandwiches the upper connecting member 21 between the lower connecting member 22 and the bottom plate 3c. This adjusts the movement of the composite panel 1 (in a direction intersecting the surface of the composite panel 1 facing the living space) and ensures that the surfaces of the upper composite panel 1a and the lower composite panel 1b are flush with each other. This also prevents the composite panel 1 from peeling off toward the living space. Furthermore, the relative positional shift between the lower connecting member 22 and the upper connecting member 21 allows the composite panel 1 to accommodate building displacement. This allows the surfaces of the composite panels 1a and 1b arranged adjacently above and below to remain flush even if the building is displaced.

[0054] [Effects of the first embodiment] The first embodiment as described above can provide the following effects. (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 make up the finishing material 2 are also made thinner, which also contributes to the lighter weight of the finishing material 2.

[0055] (1-2) The mounting structure 6 fixes the anchor nut 12 to the hole 11 of the honeycomb panel 3 by adhesive and welding. Therefore, it is stronger than, for example, a case where the anchor nut 12 is fixed to the hole 11 only by adhesive 13. Furthermore, 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 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 an intervening 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) The composite panel 1 is lightweight, which simplifies the structure of the base part 9 and the mounting members, thereby narrowing the space behind the composite panel 1. This in turn increases the effective living space and floor area.

[0059] (1-7) The composite panel 1 is also excellent in earthquake resistance because each panel is attached to the base 9 via the attachment 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 peripheral end of the flange portion 12b, thereby making it possible to further increase the welding strength.

[0060] (1-9) The overlapping of the upper connecting member 21 and the lower connecting member 22 adjusts access and allows the surfaces of the adjacent composite panels 1a, 1b arranged vertically to be flush. This also prevents the composite panel 1 from peeling off into the living space. Furthermore, the shifting of the relative positions of the lower connecting member 22 and the upper connecting member 21 allows the panels to follow the displacement of the building. This allows the surfaces of the adjacent composite panels 1a, 1b arranged vertically to remain flush, even if the building is displaced.

[0061] (1-9) The engagement 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.

[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, which is 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 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 with 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 has a fixing hole whose major axis is the horizontal direction in which the duct channel 63 extends. The duct channel 63 arranged in the second fixing portion 61b is fixed with a fastening member 65, such as an M6 bolt, a nut, or the like.

[0064] The duct channel 63 has a cross-sectional recessed shape with a groove formed therein. The duct channel 63 extends, for example, horizontally so as to intersect with the corner stud 9a. The duct channel 63 is placed 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 placed in the groove of the duct channel 63, and the second metal plate 66b is placed on the groove of the duct channel 63.

[0065] The second fixing bracket 62 is, for example, an L-shaped bracket. It includes a first piece 62a and a second piece 62b. The first piece 62a extends in the vertical direction. The first piece 62a includes a loose hole 62c. In the bottom plate 3c of the honeycomb panel 3, the flange 12b protrudes from the surrounding surface of the bottom plate 3c by the thickness of the flange 12b. The loose hole 62c, formed by welding the outer periphery of the flange 12b to the bottom plate 3c, is larger than the protruding portion of the flange 12b and has a size that allows the protruding portion to escape. In other words, 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 greater than the protruding height of the flange 12b. The loose hole 62c is an elongated hole with its major axis extending in the vertical direction. A presser 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 presser plate 67 is placed thereon. These are then fixed to the nut portion 12a with 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 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 its long axis in the front-to-rear direction. The second piece 62b is then overlapped with the first metal plate 66a and the second metal plate 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 a nut portion 12a with a bolt 72. The lower connecting member 71 is a rectangular plate material and includes a first portion 71a, which is the upper portion, and a second portion 71b, which is the lower portion. The first portion 71a is fastened to the nut portion 12a with the bolt 72. The second portion 71b extends toward the lower edge of the lower composite panel 1b, i.e., toward the lower composite panel 1b. The second portion 71b has a bent portion 71c whose tip is away from the bottom plate 3c. The bent portion 71c extends over the joint 19.

[0068] A lower plate 73 is disposed on the bottom plate 3c. The lower plate 73 is a rectangular metal plate, for example, having the same thickness as the first piece 62a. The lower plate 73 has a loose hole 73a. The loose hole 73a is larger than the protruding portion of the flange 12b and is large enough to accommodate the protruding portion. The second portion 71b sandwiches the tip end 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, pressing the tip end 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 fine-tuned within the range of the loose hole 62c.

[0069] The upper portion of the first piece 62a and the second portion 71b overlap to adjust for entry and exit, allowing the surfaces of the adjacent composite panels 1a, 1b arranged vertically to be flush. This also prevents the composite panel 1 from peeling off toward the living space. Furthermore, the upper portion of the first piece 62a and the second portion 71b can follow the displacement of the building by shifting their relative positions. This allows the surfaces of the adjacent composite panels 1a, 1b arranged vertically to remain flush. In this embodiment, either the loose hole 62c or 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 so as to be suspended by the mounting plate 31. Furthermore, 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 arranged on both sides of the upper long side of the composite panel 1. The connecting plates 41 are arranged on both sides of the lower long side of the composite panel 1. For example, on the upper long side, they are arranged at a position about 1 / 4 to 1 / 34, preferably about 1 / 8, of the length of the long side from each of the left and right short sides. The connecting plates 41 are arranged 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 9 at a position overlapping the lower portion of the upper composite panel 1a.

[0073] The mounting plate 31 is a rectangular metal plate. 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 via smaller bolts 16, such as M6 bolts, than conventional bolts. In the second embodiment, the mounting plate 31 is attached to the base portion 9, so the space behind the composite panel 1 is narrower than in the first embodiment. Therefore, low-head bolts or ultra-low-head bolts are used for the bolts 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 via fixing bolts 32, such as drilling tapping screws. In other words, the lower composite panel 1b is attached by the mounting plate 31 so as to be suspended from a position overlapping the upper composite panel 1a, spanning 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 also functions as a displacement portion, and when a load is applied in the inward / outward direction, the second portion 31b displaces toward the base portion 9, thereby absorbing the impact applied to the composite panel 1 together with the adhesive 42. Furthermore, the mounting plate 31 can also displace in response to displacement of the building. This allows the surfaces of the vertically adjacent composite panels 1a, 1b to remain flush, even if the building is displaced.

[0074] The connecting plate 41 is a rectangular metal plate. The connecting plate 41 is arranged next to the inside of the mounting plate 31. In the example of FIG. 14 , the first portion 41a, which is the upper portion, is fastened to the nut portion 12a that constitutes the lower mounting structure 6b of the upper composite panel 1a. The second portion 41b, which is the lower portion of the connecting plate 41, extends to the upper portion of the lower composite panel 1b. The upper and lower composite panels 1a, 1b are fixed to the base portion 9 together with the connecting plate 41 by an 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 attached together around the periphery of 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 adhesively fixed to the base portion 9 and the bottom plate 3c of the upper and lower composite panels 1a and 1b with an adhesive 42. The second portion 41b is in contact with the bottom plate 3c of the lower composite panel 1b. This allows for adjustment of the inward / outward direction and allows the surfaces of the adjacent composite panels 1a and 1b arranged vertically to be flush with each other. This also prevents the composite panel 1 from peeling off into the living space. Furthermore, the adhesive 42 can absorb impacts applied to the composite panel 1. Furthermore, the connecting plate 41 can also move in response to the displacement of the building. This allows the surfaces of the adjacent composite panels 1a and 1b arranged vertically to remain flush with each other, even if the building is displaced.

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

[0077] (2-1) The composite panel 1 can be attached to the base portion 9 by hanging 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 accordance with the displacement of the building. This allows the surfaces of the vertically adjacent composite panels 1a and 1b to remain flush 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 adhesively fixed to the base portion 9 with the adhesive 42 with the second portion 41b in contact with the bottom plate 3c. This allows for adjustment of the inward and outward movement during installation, and allows the surfaces of the vertically adjacent composite panels 1a, 1b to be arranged flush. This also prevents the composite panel 1 from peeling off into 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 in accordance with the displacement of the building. This allows the surfaces of the vertically adjacent composite panels 1a, 1b to remain flush even if the building is displaced.

[0079] [Modification of Figure 14] As shown in Figure 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 presser plate 83 is disposed in the first portion 81a. The presser plate 83 is placed on top of 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 the upper composite panel 1a.

[0080] A lower connecting member 86 provided on the lower portion of the upper composite panel 1a is fastened to the nut portion 12a via a bolt 87. The lower connecting member 86 is a rectangular plate material and includes a first portion 86a, which is the upper portion, and a second portion 86b, which is the lower portion. The first portion 86a is fastened to the nut portion 12a via the bolt 87. The second portion 86b extends toward the lower edge of the lower composite panel 1b, i.e., toward the lower composite panel 1b. The second portion 86b includes a bent portion 86c whose tip is away from the bottom plate 3c. The bent portion 86c extends onto 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 a 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 overlapping of the second portion 81b and the second portion 86b adjusts access and allows the surfaces of the adjacent composite panels 1a and 1b arranged vertically to be flush with each other. This also prevents the composite panel 1 from peeling off toward the living space. Furthermore, the second portion 81b and the second portion 86b can follow the displacement of the building by shifting their relative positions. This allows the surfaces of the adjacent composite panels 1a and 1b arranged vertically to remain flush with each other even if the building is displaced.

[0083] [Modification of the stopper] As shown in FIG. 16, the stopper 91 has a fixing portion 91a and an extending portion 91b. The stopper 91 is formed by bending a rectangular metal plate (for example, with a thickness of about 1 mm). The fixing portion 91a is a piece extending on the bottom plate 3c of the honeycomb panel 3, and is fixed to the bottom plate 3c by tightening a fixing bolt 8a to the honeycomb panel 3. The extending portion 91b is formed by bending, for example, at 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, with its tip extending to the end face of the finishing material 2. In this example, an engaging portion 7c like that shown in the stopper 7 in FIG. 10 is not provided.

[0084] As shown in FIG. 17, the stopper 91 configured as described above has the fixing portion 91a placed 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 tightening 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 placed 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 first and second embodiments can be further modified as follows. [Modification of the stopper (see Figure 10)] In the first and second embodiments, the positions where the stoppers 7 are provided and the number of stoppers 7 are not limited to the examples described above. That is, in addition to or instead of the arrangements 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 each of the top and bottom long sides, and one stopper may be provided at the center of each of the left and right short sides. Furthermore, the stoppers 7 may be provided only 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. Although this configuration also eliminates the function of preventing the composite panel 1 from peeling off into the living space, it allows the surfaces of the composite panels 1a and 1b adjacent to each other vertically to be arranged flush with each other.

[0087] [Modification of 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 outside the mounting plate 31, or 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 plates 41 may be disposed not only at two locations on both sides of the lower long side of the upper composite panel 1a, but also at one or more locations between them. In this case, the mounting structure 6 is provided at the location where the connecting plates 41 are to be 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 Figures 12 and 13)] The mounting plates 31 may be disposed not only in two locations on both sides of the upper long side of the lower composite panel 1b, but also in one or more locations between them. In this case, the mounting structure 6 is provided at the location 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 surfaces of the upper composite panel 1a and the lower composite panel 1b to be flush with each other. It also prevents the composite panel 1 from peeling off into the living space.

[0093] The structure for attaching the composite panel 1 to the base portion 9 using the fastening brackets 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 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 fastening brackets may be added between them (see Figure 2).

[0094] The upper connecting member 21 may be attached to a new upper mounting structure 6a using bolts, separate 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] [Modification 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 the outer circumferential edge, that is, the boundary portion, as long as the required 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 on the back surface of the finishing material 2 rather than on 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 of the finishing material 2 in the thickness direction. 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, there are no particular limitations on the materials used to weld the flange 12b of the anchor nut 12 and the bottom plate 3c of the honeycomb panel 3. For example, the honeycomb core 3a may be made of aluminum, and the top plate 3b and / or 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, but may be a polygonal panel such as a triangle, pentagon, or hexagon, or may be a circular or elliptical panel. Composite panels 1 of the same shape may not only be arranged on the base 9, but also composite panels 1 of various shapes may be attached to the base 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 an exterior wall of a building. According to the above embodiment and its modified examples, the following technical ideas can be further derived. (Appendix 1) A composite panel mounting structure in which a composite panel formed by fixing a finishing material to one surface of a honeycomb panel is fixed to a base part, The composite panels include 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 provided in the upper composite panel at a position offset downward from the center in the vertical direction, and an upper mounting structure provided in the lower composite panel at a position offset upward from the center in the vertical direction, a lower connecting member extending from the lower mounting structure toward the upper mounting structure; an upper connecting member extending 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 for composite panels, it is desirable to improve the work efficiency of mounting the composite panel to the substrate. According to the above-mentioned configuration, the honeycomb panel and one of the lower connecting member and the upper connecting member are sandwiched between the other connecting member. This makes it possible to easily mount adjacent composite panels arranged vertically so that their surfaces are flush with each other.

[0102] (Appendix 2) A composite panel is formed by fixing a finishing material to one surface of a honeycomb panel with an adhesive. The stopper structure connects the honeycomb panel and the finishing material, 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 be made lighter while maintaining the strength of the composite panel. However, the finishing material is often bonded to one surface of the honeycomb panel with an adhesive. Therefore, it is desirable to further improve the reliability of composite panels by preventing the finishing material from falling off the honeycomb panel.

[0104] 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, thereby preventing 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 engaging portion that engages with the groove. (Appendix 3) Mounting structure for a composite panel.

[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 that make up not only the bottom surface of the finishing material but also the top 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. Furthermore, it is possible to further improve reliability. [Explanation of symbols]
