Description

[Technical Field]

[0001] The present disclosure relates to a panel structure in which a plurality of panel bodies are joined together. [Background technology]

[0002] Conventionally, in panel structures that constitute eaves, roofs, side walls, etc., a panel body is known that is formed by joining multiple plate materials in the width direction. Also known is a panel that is formed by connecting multiple such panel bodies to form an even larger panel.

[0003] For example, Patent Document 1 discloses a configuration in which the connecting portions of individual panels, which are metal extrusion hollow moldings, are connected to form a panel. The panels are connected using first and second panel connectors, which are metal extrusion hollow moldings. Each panel connector has a connecting plate portion provided along the entire length on the side end face of the terminal panel, and the connecting plate portions protruding from adjacent panels are overlapped and connected with screws. Joint grooves created by connecting the panels are sealed with a joint sealant. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-145779 Summary of the Invention [Problem to be solved by the invention]

[0005] In such metal extrusion molded products, the brightness of the component changes depending on the relationship between the position of the light source relative to the component and the position of the viewer relative to the component, as well as the optical properties of the component. In this case, if components with significantly different optical properties are connected and arranged on the same plane, the difference in color tone between the two components is emphasized, making the viewer more likely to perceive color unevenness and reducing the design quality.

[0006] Furthermore, these extruded shapes have the problem that the optical properties of the component change depending on the shape, which can easily lead to differences in color tone between components. In other words, if the billet pulling speed or billet heating temperature differs depending on the shape of the extruded shape, these differences will affect the optical properties of the surface of the extruded shape. In addition, these extruded shapes are generally subjected to coating treatments such as anodizing, but if the coating treatment conditions differ (for example, if the shape of the extruded shape differs or if the chemical concentration or temperature differs between production lots), this will also cause unevenness in the product color tone.

[0007] As such, extruded profiles are prone to differences in optical properties due to their different shapes. Therefore, when extruded profiles of different shapes are connected and arranged on the same plane, the difference in optical properties between the components may be perceived as color unevenness. For example, in the invention described in Patent Document 1, the shapes of the panel itself and the panel connector are different, so the difference in optical properties between the two may be perceived as color unevenness. As a result, color unevenness may be seen on both sides of the joint sealant, which significantly impairs the design.

[0008] In addition, in the invention described in Patent Document 1, the width of the joint groove (clearance) is determined and fixed by the width of the connecting plate part of the panel connector. With this configuration, it is not possible to adjust for errors due to the dimensional tolerance of the individual panel, which may cause problems during construction. The present disclosure aims to provide a panel structure that can reduce the problem of color unevenness caused by differences in the shapes of components. [Means for solving the problem]

[0009] A panel structure according to one aspect of the present disclosure is a panel structure in which a plurality of panel bodies are connected together, the panel bodies comprising a plurality of plate materials joined together in the width direction and connecting members attached to the widthwise ends of the panel bodies, and an adjustment clearance can be formed between adjacent connecting members, and a decorative material is attached to at least one surface of the panel bodies so as to cover the adjacent connecting members and the clearance. [Effects of the Invention]

[0010] According to the present disclosure, a decorative material is attached to at least one surface of the panel body so as to cover adjacent connecting members and clearances, so that the connecting members and clearances where an observer may perceive color unevenness can be covered with the decorative material, thereby reducing the problem of color unevenness caused by different shapes of components.

[0012] An embodiment of the present invention will be described using an example in which a panel structure 10 is used as a building eave. In the following description, the horizontal direction in which the panel structure 10 protrudes is referred to as the front, and the side of the building skeleton (the opposite direction from the front) as viewed from the panel structure 10 is referred to as the rear. This front-to-rear direction is referred to as the depth direction D of the panel structure 10, and the horizontal direction perpendicular to the depth direction D is referred to as the width direction W. The vertical direction is referred to as the height direction H (up-down direction).

[0013] The panel structure 10 of this embodiment is attached to the eaves of a building to block direct sunlight, rainwater, etc., and as shown in Figures 1, 5, 7, etc., it comprises a plurality of panel bodies 11, a base frame 20, a base angle 21, a base cover 23, a base lid 25, a tip frame 28, a tip cover 29, a tip lid 30, a lower base cover 31, and a decorative material 17.

[0014] The panel body 11 is formed by joining multiple members in the width direction W, and the upper and lower surfaces are flush. The panel body 11 includes multiple plate members 12 joined in the width direction W and connecting members (at least one of first connecting members 15 and second connecting members 16) attached to the ends of the panel body 11 in the width direction W. The width of the panel body 11 can be adjusted by increasing or decreasing the number of plate members 12. The plate members 12 and connecting members are hollow, elongated members, such as aluminum extrusions. The plate members 12 and connecting members are all formed to the same length, and the height dimensions (thickness) of the top and bottom are also set to be approximately the same. The panel body 11 is supported by a base frame 20 (described later) so that the leading end thereof is inclined downward. The panel structure 10 according to this embodiment is formed by combining multiple panel members 11 in the width direction W.

[0015] The base frame 20 is a long member for supporting the panel body 11 and other members, and is attached to a wall surface 80 of the building skeleton as shown in FIG. 7(b). The base frame 20 according to this embodiment is fixed to the wall surface 80 of the building with mounting bolts 20a and mounting nuts 20b that are attached to the wall surface 80 in advance. The panel body 11 is attached to the front surface of this base frame 20. The mounting bolts 20a and mounting nuts 20b may be attached after the position of the base frame 20 has been determined.

[0016] The base angle 21 is a member that cooperates with the base frame 20 to support the plate material 12. Specifically, as shown in FIG. 7(b), the plate material 12, whose underside is supported by the base frame 20, is pressed down from above by the base angle 21, and the base frame 20 and the base angle 21 sandwich and support the plate material 12 from both the top and bottom. As shown in FIG. 5, the base angle 21 is shorter than the base frame 20 when viewed in the width direction W, and multiple base angles 21 are used at predetermined intervals. The base angles 21 according to this embodiment are arranged so as to straddle the joints of the plate materials 12, so that all the plate materials 12 can be held with a fewer number of base angles 21 than the plate materials 12 (for example, one for every two plate materials 12). Note that the same number of base angles 21 as the plate materials 12 may be used.

[0017] The base cover 23 is a cover member attached to cover the top surfaces of the base frame 20 and the base angle 21. As shown in FIG. 1(a), the base cover 23 covers the joints between the base frame 20 and the panel body 11 (all of the areas where they come into contact and join together) so as not to be exposed. In this embodiment, the base angle 21 is completely covered by the base cover 23. The base cover 23 prevents rainwater from falling directly onto the base frame 20 and the base angle 21. The base cover 23 is inclined so that rainwater flows toward the plate material 12 in front of it.

[0018] 1(a), the base lid 25 is a cover member attached to the side end (small edge) of the base frame 20. The base lid 25 is fixed to both ends of the base frame 20 with screws or the like.

[0019] The tip frame 28 is a member for attaching a tip cover 29, which will be described later, to the panel body 11. The tip frame 28 according to this embodiment is a long member with a substantially L-shaped cross section, as shown in Fig. 7(a). The tip frame 28 is attached to the tip of the panel body 11 with screws (not shown).

[0020] The tip cover 29 is a long cover material that covers the tip of the panel body 11. The tip cover 29 is attached to the tip frame 28 by tip cover screws 29a.

[0021] 1(a), the tip lid 30 is a cover member attached to the side end (small edge) of the tip cover 29. The tip lid 30 is fixed to both ends of the tip cover 29 with screws or the like. The lower base cover 31 is a cover member attached to cover the lower surface of the base frame 20.

[0022] The decorative material 17 is a member attached so as to cover the joints between adjacent panel bodies 11. In this embodiment, as shown in FIG. 1(b), the decorative material 17 is attached only to the underside of the panel body 11. The decorative material 17 may be attached to both sides of the panel body 11, but it is not necessary to attach the decorative material 17 to the side that is not visible. This decorative material 17 is, for example, an extruded member made of aluminum. This decorative material 17 is a long material that is approximately the same length as the panel body 11, but it may be formed slightly shorter than the panel body 11. That is, as shown in FIG. 7, the front and rear ends may be formed slightly shorter to avoid interference with the tip cover 29 and the lower base cover 31. The specific shapes of the plate material 12, the first connecting material 15, the second connecting material 16, and the decorative material 17 will be described in detail below.

[0023] As shown in Fig. 2, the plate material 12 according to this embodiment includes an upper plate portion 40 and a lower plate portion 41 that are parallel to each other, and a hollow portion is provided between the upper plate portion 40 and the lower plate portion 41. A plurality of vertical walls extending in the up-down direction are provided between the upper plate portion 40 and the lower plate portion 41. In this embodiment, these vertical walls include side wall portions 42 on both the left and right sides, and an intermediate wall portion 43 is provided between the side wall portions 42. The hollow portion is defined by these vertical walls.

[0024] Furthermore, these plates 12 have a first joint 50 and a second joint 60 on both sides. For example, in the cross-sectional view of FIG. 2(a), the first joint 50 is provided on the right side and the second joint 60 is provided on the left side. Adjacent plates 12 are joined to each other by engagement between the first joint 50 provided on one plate 12 and the second joint 60 provided on the other plate 12. Although not specifically shown in the present embodiment, plate members 12 that are joined to other members on only one side (plate members 12 arranged on the left and right ends of the panel structure 10) may have a joint only on the side that is joined to the other member.

[0025] The first joint portion 50 is a modified, generally U-shaped portion that opens to the side. The first joint portion 50 includes a first side wall portion 52 that is the side wall portion 42 that defines the first joint portion 50, a first upper protrusion 51 that protrudes laterally beyond the first side wall portion 52 by extending the upper plate portion 40, and a first lower protrusion 53 that protrudes laterally beyond the first side wall portion 52 by extending the lower plate portion 41. These protrusions are formed to engage with adjacent plate materials 12. A rotation shaft portion 51a is formed at the tip of the first upper protrusion portion 51. At least the lower surface of the rotation shaft portion 51a is formed as a curved surface (preferably a semi-cylindrical curved surface).

[0026] An arc-shaped portion 52a is provided at the upper end of the first side wall portion 52 so as to be continuous with the lower surface of the upper plate portion 40. The arc-shaped portion 52a is formed in an arc shape that follows the circumferential surface of the rotation shaft portion 51a. With this configuration, an arc-shaped guide groove 52b is formed between the rotation shaft portion 51a and the arc-shaped portion 52a, and the rotation shaft portion 51a is disposed above this guide groove 52b.

[0027] Furthermore, a straight portion 52d extending substantially vertically downward is connected to the first side wall portion 52 below the guide groove 52b (arcuate portion 52a). An inclined portion 52c is connected below this straight portion 52d. This inclined portion 52c is inclined inward (opposite the opening direction of the first joint portion 50) as it extends downward.

[0028] The first lower protrusion 53 includes a flat plate portion 53a continuous with the lower plate portion 41, a rising portion 53b extending upward from the end of the flat plate portion 53a, and an arc-shaped curved piece 53c extending diagonally upward from the upper end of the rising portion 53b. The curved piece 53c is formed in an arc shape centered on the rotation shaft 51a below the rotation shaft 51a. Note that the curved piece 53c does not have to be completely arc-shaped centered on the rotation shaft 51a, as long as it has a shape that follows the outer periphery of the rotation shaft 51a.

[0029] The space surrounded by the first side wall portion 52 and the first lower protrusion portion 53 is groove-shaped and opens upward, forming an intermediate gutter portion 54 for receiving water that seeps in through the joined joints. This intermediate gutter portion 54 allows water to flow in the longitudinal direction of the plate material 12. In this embodiment, a portion of the first side wall portion 52 is formed at an angle (having an inclined portion 52c), thereby ensuring a large volume for the intermediate gutter portion 54 (the maximum volume of water that can be received in the gutter). Furthermore, because the curved piece 53c protrudes laterally in an arc, the volume of the intermediate gutter portion 54 is further increased.

[0030] Next, the second joint 60 joined to the first joint 50 will be described. The second joint 60 is also a modified, generally U-shaped portion that opens laterally. The second joint 60 includes a second side wall 62, which is the side wall 42 that defines the second joint 60, a second upper protrusion 61 that protrudes laterally beyond the second side wall 62 (i.e., beyond the hollow portion) by extending the upper plate 40, and a second lower protrusion 63 that protrudes laterally beyond the second side wall 62 (i.e., beyond the hollow portion) by extending the lower plate 41. These protrusions are formed to engage with adjacent plate members 12.

[0031] A pivot receiving portion 61a is formed at the tip of the second upper protrusion 61. The pivot receiving portion 61a has an arc-shaped inner peripheral surface that opens upward. This pivot receiving portion 61a can support the pivot shaft portion 51a of the first joint portion 50 from below. This pivot receiving portion 61a can rotatably support the placed pivot shaft portion 51a. Furthermore, this pivot receiving portion 61a can be inserted into the guide groove 52b of the first joint portion 50. Because the guide groove 52b has the same arc shape as the pivot receiving portion 61a, it can rotatably support the inserted pivot receiving portion 61a. With this configuration, the first joint portion 50 and the second joint portion 60 can be rotated relative to each other, making it easy to join the plate materials 12. This joining method will be described in detail later.

[0032] The second side wall 62 also includes a support groove 62a into which the tip of the curved piece 53c of the first joint 50 is inserted. When the first joint 50 and the second joint 60 are joined, the curved piece 53c is inserted into the support groove 62a, allowing it to withstand loads in the vertical and horizontal directions, thereby increasing the strength of the joint. In other words, support is provided at two points—the pivot receiver 61a inserted into the guide groove 52b and the curved piece 53c inserted into the support groove 62a—resisting loads in the vertical and horizontal directions. Furthermore, as shown in FIG. 2(c) , a labyrinth shape is formed at the tip of the intermediate trough 54, preventing water from leaking to the underside of the plate 12. The support groove 62a is formed slightly wider than the thickness of the curved piece 53c, allowing the curved piece 53c to be loosely fitted within the support groove 62a. In other words, the curved piece 53c is inserted into the support groove 62a with a gap around it. It is desirable that the support groove 62a and the curved piece 53c are formed so as not to come into contact with each other when the first joint portion 50 and the second joint portion 60 are rotated to join together. By loosely fitting the curved piece 53c into the support groove 62a in this way, no force is required when joining or separating the plate material 12, making the work easy.

[0033] Additionally, an upwardly bent erected portion 63a is formed at the tip of the second lower protrusion 63. This erected portion 63a abuts against the rising portion 53b when the first joint portion 50 and the second joint portion 60 are joined. The abutment of this erected portion 63a against the rising portion 53b supports adjacent plate materials 12 in a flat state relative to each other. Furthermore, the formation of this erected portion 63a creates a groove-shaped space surrounded by the second side wall portion 62 and the second lower protrusion 63, forming a secondary gutter portion 64. As shown in FIG. 2(c), this secondary gutter portion 64 is positioned below the intermediate gutter portion 54 so as to overlap it and can catch water that leaks outside the intermediate gutter portion 54. The provision of this secondary gutter portion 64 allows water to be caught even if it infiltrates behind the curved piece 53c.

[0034] The first and second joints 50 and 60 can be joined by inserting either one of them obliquely from above and rotating it downward. For example, as shown in FIG. 2(b), the second joint 60 is tilted obliquely and inserted into the first joint 50 from above so that the rotation receiving portion 61a fits into and catches in the guide groove 52b. Then, as shown in FIG. 2(c), the second joint 60 is rotated downward so that the erect portion 63a abuts against the rising portion 53b. This operation joins two adjacent plate materials 12 flat to each other. At this time, the curved piece 53c is automatically inserted into the support groove 62a.

[0035] The first joint portion 50 and the second joint portion 60 are formed over the entire length of the plate material 12. Therefore, after the first joint portion 50 and the second joint portion 60 are joined, the plate material 12 can be slid in the depth direction D of the panel structure 10. Therefore, after the plate material 12 is joined, it can be slid to the mounting position (towards the base frame 20) and fixed to the base frame 20, which improves workability.

[0036] An irregular wood grain pattern is formed on the underside of these boards 12. This wood grain pattern is formed along the longitudinal direction of the boards 12, and by making the spacing and height irregular, a natural wood grain can be expressed. By forming the wood grain, the design characteristics of the wood grain can be utilized, and the joints between the boards 12 become less noticeable, resulting in a good design. Furthermore, since the wood grain can be formed during extrusion molding, manufacturing is easy. In this embodiment, the wood grain is formed along the direction of extrusion molding, but this is not limited to this, and the wood grain may be formed in a direction perpendicular to the direction of extrusion molding.

[0037] As shown in Fig. 3, the first connecting member 15 and the second connecting member 16 are a pair of members attached to the ends of adjacent panel bodies 11 so as to face each other. For two adjacent panel bodies 11, the first connecting member 15 is attached to one end, and the second connecting member 16 is attached to the other end. More specifically, the first connecting member 15 is joined to the plate member 12A, of the plate members 12 constituting one panel body 11, that is closest to the other panel body 11. The second connecting member 16 is joined to the plate member 12B, of the plate members 12 constituting the other panel body 11, that is closest to the one panel body 11.

[0038] As shown in Fig. 4(a), the first connecting member 15 has a first joint portion 50 that can be joined to the second joint portion 60 of the plate material 12. That is, the first joint portion 50 is formed at one end portion as viewed in the width direction W. The other end portion has a substantially rectangular shape and has a vertical wall portion 15a that forms a surface perpendicular to the upper and lower surfaces.

[0039] The first connecting member 15 includes an upper plate portion 40 and a lower plate portion 41 that are parallel to each other, and a hollow portion between the upper plate portion 40 and the lower plate portion 41. A plurality of vertical walls extending in the vertical direction are provided between the upper plate portion 40 and the lower plate portion 41. In this embodiment, as the vertical walls, a side wall portion 42 is provided on the right side, a vertical wall portion 15a is provided on the left side, and an intermediate wall portion 43 is provided between the side wall portion 42 and the vertical wall portion 15a. The hollow portion is defined by these vertical walls.

[0040] This first connecting material 15 has a first joint portion 50 that has the same shape as the first joint portion 50 of the plate material 12. As shown in FIG. 3(b), the first connecting material 15 can be joined to an adjacent plate material 12A by using this first joint portion 50. The shape of the first joint portion 50 of this first connecting material 15 is the same as the first joint portion 50 of the plate material 12, so a description thereof will be omitted.

[0041] As shown in FIG. 4(b), the second connecting member 16 is a long member having a modified U-shaped cross section. This second connecting member 16 has a second joint 60 that can be joined to the first joint 50 of the plate material 12 described above. That is, the second joint 60 is formed at one end as viewed in the width direction W. The other end is closed. As shown in FIG. 3(b), the second connecting member 16 can be joined to an adjacent plate material 12B using this second joint 60.

[0042] The second connecting member 16 comprises a second upper protrusion 61 formed horizontally on the upper surface side, a second lower protrusion 63 formed horizontally on the lower surface side, and a vertical wall portion 16a and an arc-shaped receiving portion 16c arranged to connect the second upper protrusion 61 and the second lower protrusion 63.

[0043] A rotation receiving portion 61a is formed at the tip of the second upper protrusion 61. The rotation receiving portion 61a has an arc-shaped inner peripheral surface that opens upward, and is similar to the rotation receiving portion 61a of the plate material 12 already described.

[0044] Furthermore, an upwardly bent erected portion 63a is formed at the tip of the second lower protrusion 63. This erected portion 63a abuts against the rising portion 53b when the first joint portion 50 and the second joint portion 60 are joined, and is similar to the erected portion 63a of the plate material 12 already described.

[0045] The vertical wall portion 16a extends downward at a right angle from the end of the second upper protrusion 61. This vertical wall portion 16a forms a surface perpendicular to the upper and lower surfaces. An L-shaped protrusion 16b is provided on the surface of this vertical wall portion 16a facing the opening direction of the second joint portion 60 (leftward in FIG. 4(b)). This L-shaped protrusion 16b forms a downward-facing L-shape with its tip protruding in the same direction as the second upper protrusion 61 and bent downward. The inside of this L-shaped protrusion 16b forms a roughly U-shaped groove, which forms a support groove 62a into which the tip of the curved piece 53c of the first joint portion 50 is inserted. Note that, unlike the support groove 62a of the plate material 12, the support groove 62a of the second connecting member 16 is not arc-shaped along the curved piece 53c. Therefore, it is not possible to support the curved piece 53c with a surface. However, by providing an arc-shaped receiving portion 16c, which will be described below, the curved piece 53c is supported by a surface.

[0046] The arc-shaped receiving portion 16c is a portion connected to the lower portion of the vertical wall portion 16a. This arc-shaped receiving portion 16c is formed in an arc shape so as to follow the outer peripheral surface of the curved piece 53c inserted into the support groove 62a. In this embodiment, as shown in FIG. 3(b), the arc-shaped receiving portion 16c and the curved piece 53c are overlapped, and then a fastener 19 such as a screw is attached so as to penetrate both of them. This secures the joined plate material 12B and the second connecting member 16 so that they do not come apart. At this time, the fastener 19 is inserted from diagonally below, so that the head of the fastener 19 does not protrude from the forming surface of the vertical wall portion 16a.

[0047] In this way, when the first connecting member 15 and the second connecting member 16 are attached to the plate members 12A and 12B at the ends of two adjacent panel bodies 11, respectively, the vertical wall portion 15a of the first connecting member 15 and the vertical wall portion 16a of the second connecting member 16 are parallel and face each other, as shown in FIG. 3(b). The gap between these two parallel surfaces is an adjustment clearance C for connecting the two panel bodies 11. In other words, when a large panel body 11 is constructed by connecting many plate members 12 in the width direction W, misalignment may gradually increase due to accumulation of manufacturing errors, etc. This clearance C is provided to absorb such misalignment and allows the two panel bodies 11 to be connected even with some misalignment.

[0048] The decorative material 17 is a member attached to at least one surface of the panel body 11 so as to cover the above-mentioned clearance C and the two adjacent connecting materials (the first connecting material 15 and the second connecting material 16). As shown in Fig. 4(c), the decorative material 17 has a horizontal portion 17a and a vertical portion 17c.

[0049] The horizontal portion 17a is a plate-like portion that covers the surface of the panel body 11. The horizontal portion 17a is disposed parallel to the surface of the panel body 11. As shown in FIG. 3(b), this horizontal portion 17a is attached so as to protrude from the surface (lower surface) of the panel body 11 when viewed in the thickness direction of the panel body 11. In other words, it is attached so as to appear raised to the viewer. The surface of the horizontal portion 17a in this embodiment is processed in the same way as the plate material 12. In other words, an irregular wood grain pattern is formed on the surface of the horizontal portion 17a.

[0050] Bent portions 17b are formed at both ends of the horizontal portion 17a in the width direction W, bending from the horizontal portion 17a. These bent portions 17b extend obliquely so that they approach the surface of the panel body 11 as they approach the tip. The tip of each bent portion 17b abuts against the surface of the panel body 11. When viewed in the width direction W, the decorative material 17 is attached so that the first connecting material 15 and the second connecting material 16 and the clearance C fit snugly between the two tips of the bent portions 17b.

[0051] In this embodiment, the surface finish of the bent portion 17b is intentionally different from that of the horizontal portion 17a. Specifically, the bent portion 17b has a smooth surface and does not have an irregular wood grain pattern. This intentionally gives the step formed by the bent portion 17b a different pattern, giving the observer a different impression. Note that, unlike this embodiment, the surface finish of the bent portion 17b may be the same as that of the horizontal portion 17a. Even in this case, when the panel body 11 is viewed in the thickness direction, the bent portion 17b is attached so as to protrude from the surface (lower surface) of the panel body 11 by the length of the bent portion 17b, so that even the step alone can give the observer a different impression.

[0052] The vertical portion 17c is a plate-like portion that protrudes vertically from the horizontal portion 17a. This vertical portion 17c is fixed to one of the adjacent connecting members. In this embodiment, the vertical portion 17c is overlapped with the vertical wall portion 15a of the first connecting member 15, and the two are fixed together with fasteners 19 such as screws. The vertical portion 17c has multiple protrusions 17d on the surface that is fixed to the first connecting member 15. The protrusions 17d are formed to protrude several millimeters from the surface of the vertical portion 17c along the entire longitudinal length of the vertical portion 17c. These protrusions 17d create a gap between the vertical wall portion 15a and the vertical portion 17c, allowing burrs and chips generated when the fastener 19 is attached to escape into the gap. This prevents problems during construction caused by burrs and chips.

[0053] A protruding piece 17e protrudes perpendicularly from the surface of the vertical portion 17c. The protruding piece 17e is provided near the lower end of the vertical portion 17c, and is provided below the convex portion 17d. The protruding piece 17e is connected to the vertical portion 17c in a T-shape, and a connecting member receiving portion 17f is formed at a right angle by the upper surface of the protruding piece 17e and the vertical portion 17c. The connecting member receiving portion 17f is a portion that engages with the lower tip of the first connecting member 15. That is, as shown in FIG. 3(b), the positioning of the first connecting member 15 and the connecting member receiving portion 17f is achieved by engaging the lower tip of the first connecting member 15 (the lower end of the vertical wall portion 15a) with the connecting member receiving portion 17f.

[0054] Furthermore, a support piece 17g protrudes perpendicularly from the upper surface of the horizontal portion 17a. This support piece 17g cooperates with the connecting material receiving portion 17f described above to perform positioning. That is, when the lower tip of the first connecting material 15 is engaged with the connecting material receiving portion 17f, the upper end of this support piece 17g abuts against the underside of the panel body 11. This supports the horizontal portion 17a and the surface of the panel body 11 in parallel, preventing the decorative material 17 from being attached at an angle.

[0055] The upper surface of the connecting material receiving portion 17f and the upper end of the support piece 17g are formed to be at the same height as the upper surface of the bent portion 17b. That is, the upper surface of the connecting material receiving portion 17f, the upper end of the support piece 17g, and the upper surfaces of the bent portions 17b at both ends of the horizontal portion 17a cooperate to abut against the lower surface of the panel body 11, thereby preventing the decorative material 17 from being attached in an inclined state.

[0056] When connecting the panel bodies 11 using the above-described first connecting member 15 and second connecting member 16, they can be attached to the wall surface 80, for example, using the following procedure. Note that the following procedure is only an example, and different procedures may also be used for attachment.

[0057] (1) The mounting bolt 20a is attached to the wall surface 80. For example, a base material is attached to the back side of the wall surface 80, and the mounting bolt 20a inserted from the back side is fixed to the base material. This causes the mounting bolt 20a to protrude from the wall surface 80. Note that the mounting bolt 20a does not have to be attached in advance; it can be inserted into the wall surface 80 from the side where the base frame 20 is to be attached, sandwiching the base frame 20, and fixed on the indoor side of the wall surface 80 with the mounting nut 20b.

[0058] (2) Attach the base frame 20. Specifically, the attachment bolts 20a are inserted into holes pre-formed in the base frame 20, and the attachment nuts 20b are fastened from the front.

[0059] (3) The plate material 12 is attached in order from the end. Specifically, as shown in Figure 5, the plate material 12 is placed on the horizontal piece 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, plate material 12, and base frame 20 are fixed together with the eaves fixing device 22. As shown in Figure 7(b), the eaves fixing device 22 in this embodiment is a bolt and nut that penetrates all of the base angle 21, plate material 12, and horizontal piece 27 of the base frame 20, and this eaves fixing device 22 can fix these three components together.

[0060] (4) After attaching the end plate material 12B that constitutes the panel body 11, attach the second connecting member 16 to the plate material 12B. That is, the second joint portion 60 of the second connecting member 16 is engaged with the first joint portion 50 of the plate material 12B, and the fastener 19 is attached from the outside of the arc-shaped receiving portion 16c, thereby fixing the plate material 12B and the second connecting member 16 together.

[0061] (5) The decorative material 17 is attached to the first connecting material 15. That is, the lower tip of the first connecting material 15 is engaged with the connecting material receiving portion 17f, and the fastener 19 is attached from the outside of the vertical portion 17c, thereby fixing the first connecting material 15 and the decorative material 17 together.

[0062] (6) The first connecting material 15 with the decorative material 17 attached is attached to the base frame 20. In this embodiment, the first connecting material 15 is placed on the horizontal piece 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, the first connecting material 15, and the base frame 20 are fixed together with the eave fixing device 22.

[0063] (7) The end plate material 12A is attached to the first connecting member 15. That is, the second joint portion 60 of the plate material 12A is engaged with the first joint portion 50 of the first connecting member 15, and the first connecting member 15 and the plate material 12A are fixed together. (8) Install the boards 12 in order. (9) When three or more panel bodies 11 are connected together, steps (4) to (8) are repeated. (10) After all the boards 12 have been installed, apply a joint material 18 to the top of the clearance C to fill the joint between the first connecting material 15 and the second connecting material 16. (11) Attach the base cover 23, lower base cover 31, base lid 25, tip lid 30, etc.

[0064] In this embodiment, multiple panel bodies 11 can be connected in this manner, but a clearance C is provided at the connection portion. The decorative material 17 that covers this clearance C is fixed only to one of the connecting members (first connecting member 15) and not to the other connecting member (second connecting member 16), as shown in FIG. 6(a). Therefore, the width of the clearance C can be adjusted. Specifically, as shown in FIG. 6(b), the clearance C can be minimized to a position where the first connecting member 15 and the second connecting member 16 interfere with each other. Furthermore, as shown in FIG. 6(c), the clearance C can be maximized to a position where the first connecting member 15 and the second connecting member 16 can be covered by the decorative material 17.

[0065] In the above embodiment, the plates are attached from the left side (plate 12B) to the right side (plate 12A) in the cross-sectional view shown in Fig. 3(a), but this is not limiting and the plates may be attached from the right side (plate 12A) to the left side (plate 12B). In this case, the above steps (4) to (11) are replaced with the following steps (4) to (10).

[0066] (4) After attaching the end plates 12A that make up the panel body 11, attach the first connecting material 15 to which the decorative material 17 is attached to the plate 12A. That is, engage the first joint portion 50 of the first connecting material 15 with the second joint portion 60 of the plate 12A to fix the first connecting material 15 and the plate 12A together.

[0067] (5) The first connecting material 15 is attached to the base frame 20. In this embodiment, the first connecting material 15 is placed on the horizontal piece 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, the first connecting material 15, and the base frame 20 are fixed together with the eave fixing device 22.

[0068] (6) The end plate material 12B is attached to the second connecting member 16. That is, the second joint portion 60 of the second connecting member 16 is engaged with the first joint portion 50 of the plate material 12B, and the fastener 19 is attached from the outside of the arc-shaped receiving portion 16c, thereby fixing the plate material 12B and the second connecting member 16 together. (7) Attach the plate material 12B, and then attach the plate materials 12 in order. (8) When three or more panel bodies 11 are connected together, steps (4) to (7) are repeated. (9) After all the boards 12 have been installed, apply a joint material 18 to the top of the clearance C to fill the joint between the first connecting material 15 and the second connecting material 16. (10) Attach the base cover 23, lower base cover 31, base lid 25, tip lid 30, etc.

[0069] In this way, since attachment can be made not only from the plate material 12A side but also from the plate material 12B side, it is possible to adapt to the environment and conditions of the construction site, and workability is good. In the above embodiment, the panel structure 10 is used for a building eaves whose tip end slopes downward, but the present invention is not limited to this.

[0070] For example, as shown in Figure 8, the panel structure 10 may be used for a building eave whose tip end slopes upward. In this case, a horizontal gutter 68 and a vertical gutter 69 may be provided at the end of the panel structure 10 on the wall surface 80 side.

[0071] 9, the panel structure 10 may be used for a suspended roof supported by beams 70. In the example shown in FIG. 9, the panel structure 10 is supported using spacers 73, bolts 71, nuts 72, and plates 74.

[0072] The spacer 73 is a cylindrical member disposed between the beam 70 and the panel body 11. There is no particular restriction on the material of the spacer 73, but it can be made of metal, resin, or the like. A through hole is formed inside the spacer 73, through which a bolt 71 (described later) can be inserted. This spacer 73 can provide a gap between the beam 70 and the panel body 11.

[0073] Bolt 71 passes through the interior of spacer 73 and is used to secure beam 70 to panel body 11. The tip of bolt 71 is fastened to nut 72 inside panel body 11. When bolt 71 and nut 72 are fastened, the upper edge of spacer 73 abuts against the lower surface of beam 70, and the lower edge of spacer 73 abuts against the upper surface of panel body 11. This forms a space between beam 70 and panel body 11 that is equal to the length of spacer 73.

[0074] Plate 74 is a plate-like member that is inserted into the hollow portion of the connecting member or plate material 12. By attaching nuts 72 to the tips of bolts 71 that pass through plate 74, the fastening force of the nuts 72 can be received by plate 74. This makes it possible to prevent deformation due to fastening without increasing the thickness of the connecting member or plate material 12.

[0075] In the above embodiment, the panel structure 10 is used as a building canopy, but the panel structure 10 may be used for other purposes. For example, the panel structure 10 may be used on a horizontal roof or a vertical wall.

[0076] (Variation) 10 to 15 show a modified example in which a connecting member having a different shape from the connecting material described above is used. The basic aspects of this modified example are the same as those of the above embodiment, so redundant description will be avoided and only the differences will be described.

[0077] 12(a), the first connecting member 35 according to this modification has a first joint portion 50 that can be joined to the second joint portion 60 of the plate material 12. That is, the first joint portion 50 is formed at one end portion as viewed in the width direction W. The other end portion has a substantially rectangular shape and forms a vertical wall portion 35a.

[0078] The first connecting member 35 includes an upper plate portion 40 and a lower plate portion 41 that are parallel to each other, and a hollow portion between the upper plate portion 40 and the lower plate portion 41. A plurality of vertical walls extending in the up-down direction are provided between the upper plate portion 40 and the lower plate portion 41. In this embodiment, the vertical walls include a side wall portion 42 on the right side and a vertical wall portion 35a on the left side.

[0079] This first connecting member 35 has a first joint portion 50 having a shape similar to that of the first joint portion 50 of the plate material 12. As shown in FIG. 11(b), the first connecting member 35 can be joined to an adjacent plate material 12A by using this first joint portion 50.

[0080] The first connecting member 35 has a first upper protruding portion 51 that protrudes laterally beyond the first side wall portion 52 by extending the upper plate portion 40, and a first lower protruding portion 53 that protrudes laterally beyond the first side wall portion 52 by extending the lower plate portion 41. A rotation shaft portion 51a is formed at the tip of the first upper protrusion portion 51. At least the lower surface of the rotation shaft portion 51a is formed as a curved surface (preferably a semi-cylindrical curved surface).

[0081] The first lower protruding portion 53 includes a flat plate portion 53a continuous with the lower plate portion 41, a rising portion 53b extending upward from the end of the flat plate portion 53a, and an inclined protruding piece 35c extending diagonally upward from the upper end of the rising portion 53b. By providing the inclined protruding piece 35c, an intermediate gutter portion 54 is formed between the first lower protruding portion 53 and the side wall portion 42.

[0082] An L-shaped receiving piece 35d is provided below the rising portion 53b. The L-shaped receiving piece 35d is bent into an L shape, extends slightly downward, and then protrudes parallel to the first lower protrusion 53. As a result, an L-shaped receiving portion 35e is formed inside the L-shaped receiving piece 35d. As shown in FIG. 11(b), this L-shaped receiving portion 35e is shaped to receive the standing portion 63a of the plate 12A. When the L-shaped receiving portion 35e and the standing portion 63a of the plate 12A engage with each other, the lower surface of the first connecting member 35 and the lower surface of the plate 12A are set flat. When the L-shaped receiving portion 35e and the standing portion 63a of the plate 12A engage with each other in this manner, the L-shaped receiving piece 35d and the second lower protrusion 63 of the plate 12A overlap with each other. Fasteners 19 such as screws are attached so as to penetrate both of these, thereby fixing the joined first connecting member 35 and plate material 12A so that they do not come apart. At this time, fasteners 19 are inserted from below L-shaped receiving piece 35d. A flat head screw is used for fasteners 19, and the head of fastener 19 does not protrude from the underside of L-shaped receiving piece 35d.

[0083] 12(b), the second connecting member 36 has a second joint portion 60 that can be joined to the first joint portion 50 of the plate material 12. That is, the second joint portion 60 is formed at one end portion as viewed in the width direction W. The other end portion is formed in a substantially rectangular shape and serves as a vertical wall portion 36a.

[0084] The second connecting member 36 includes an upper plate portion 40 and a lower plate portion 41 that are parallel to each other, and a hollow portion between the upper plate portion 40 and the lower plate portion 41. A plurality of vertical walls extending in the up-down direction are provided between the upper plate portion 40 and the lower plate portion 41. In this embodiment, the vertical walls include a vertical wall portion 36a on the right side and a side wall portion 42 on the left side.

[0085] This second connecting member 36 has a second joint portion 60 that has the same shape as the second joint portion 60 of the plate material 12. As shown in FIG. 11(b), the second connecting member 36 can be joined to an adjacent plate material 12B by using this second joint portion 60. The shape of the second joint portion 60 of this second connecting member 36 is the same as the second joint portion 60 of the plate material 12, so a description thereof will be omitted.

[0086] When the first connecting member 35 and the second connecting member 36 are attached to the plate members 12A and 12B at the ends of two adjacent panel bodies 11, respectively, the vertical wall portion 35a of the first connecting member 35 and the vertical wall portion 36a of the second connecting member 36 are parallel and face each other, as shown in Figure 11(b). The gap between these two parallel surfaces is an adjustment clearance C for connecting the two panel bodies 11.

[0087] The decorative material 17 is a member attached to at least one surface of the panel body 11 so as to cover the above-mentioned clearance C and the two adjacent connecting materials (the first connecting material 35 and the second connecting material 36). This decorative material 17 can have the same shape as that shown in Fig. 4(c) already described, but unlike the embodiment in Fig. 3, it is attached to the second connecting material 36 rather than the first connecting material 35. For this reason, the decorative material 17 shown in Fig. 4(c) is rotated 180 degrees horizontally and is used.

[0088] This decorative material 17 is attached to the second connecting material 36 by overlapping the vertical portion 17c with the vertical wall portion 36a of the second connecting material 36 and fixing them together with fasteners 19 such as screws. At this time, the lower tip of the second connecting material 36 (the lower end of the vertical wall portion 36a) engages with the connecting material receiving portion 17f.

[0089] When connecting the panel bodies 11 using the first connecting member 35 and the second connecting member 36, they can be attached to the wall surface 80, for example, in the following procedure. Note that the following procedure is only an example, and different procedures may be used for attachment.

[0090] (1) The mounting bolt 20a is attached to the wall surface 80. For example, a base material is attached to the back side of the wall surface 80, and the mounting bolt 20a inserted from the back side is fixed to the base material. This causes the mounting bolt 20a to protrude from the wall surface 80. Note that the mounting bolt 20a does not have to be attached in advance; it can be inserted into the wall surface 80 from the side where the base frame 20 is to be attached, sandwiching the base frame 20, and fixed on the indoor side of the wall surface 80 with the mounting nut 20b.

[0091] (2) Attach the base frame 20. Specifically, the attachment bolts 20a are inserted into holes pre-formed in the base frame 20, and the attachment nuts 20b are fastened from the front.

[0092] (3) The plate materials 12 are attached in order from the end. Specifically, as shown in Fig. 13, the plate materials 12 are placed on the horizontal pieces 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, plate materials 12, and base frame 20 are integrally fixed with the eaves fixing device 22. Attachment is continued up to the end plate material 12B that constitutes the panel body 11.

[0093] (4) The decorative material 17 is attached to the second connecting material 36. That is, the lower tip of the second connecting material 36 is engaged with the connecting material receiving portion 17f, and the fastener 19 is attached from the outside of the vertical portion 17c, thereby fixing the second connecting material 36 and the decorative material 17 together.

[0094] (5) The second connecting member 36 with the decorative material 17 attached thereto is attached to the plate material 12B. That is, the second joint portion 60 of the second connecting member 36 is engaged with the first joint portion 50 of the plate material 12B, and the plate material 12B and the second connecting member 36 are fixed together.

[0095] (6) The first connecting member 35 is attached to the plate material 12A and fixed with the fastener 19. That is, the first joint portion 50 of the first connecting member 35 is engaged with the second joint portion 60 of the plate material 12A, and the fastener 19 is attached from the underside of the L-shaped receiving portion 35e, thereby fixing the plate material 12A and the first connecting member 35 together. (7) The plate material 12A to which the first connecting material 35 is attached is attached to the base frame 20. (8) Install the boards 12 in order. (9) When three or more panel bodies 11 are connected together, steps (4) to (8) are repeated. (10) After all the boards 12 have been installed, apply the joint material 18 to the top of the clearance C to fill the joint between the first connecting material 35 and the second connecting material 36. (11) Attach the base cover 23, lower base cover 31, base lid 25, tip lid 30, etc.

[0096] In the above embodiment, the plates are attached from the left side (plate 12B) to the right side (plate 12A) in the cross-sectional view shown in Fig. 11(a), but this is not limiting and the plates may be attached from the right side (plate 12A) to the left side (plate 12B). In this case, the above steps (3) to (11) are replaced with the following steps (3) to (10).

[0097] (3) The plate materials 12 are attached in order from the end. Specifically, as shown in Fig. 13, the plate materials 12 are placed on the horizontal pieces 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, plate materials 12, and base frame 20 are integrally fixed with the eaves fixing device 22. Attachment is continued up to the end plate material 12A that constitutes the panel body 11.

[0098] (4) The first connecting member 35 is attached to the plate material 12A and fixed with the fastener 19. That is, the first joint portion 50 of the first connecting member 35 is engaged with the second joint portion 60 of the plate material 12A, and the fastener 19 is attached from the underside of the L-shaped receiving portion 35e, thereby fixing the plate material 12A and the first connecting member 35 together.

[0099] (5) The first connecting member 35 is attached to the base frame 20. In this embodiment, the first connecting member 35 is placed on the horizontal piece 27 of the base frame 20 and sandwiched from above by the base angle 21, and the base angle 21, the first connecting member 35, and the base frame 20 are fixed together with the eave fixing device 22.

[0100] (6) The decorative material 17 is attached to the second connecting material 36. That is, the lower tip of the second connecting material 36 is engaged with the connecting material receiving portion 17f, and the fastener 19 is attached from the outside of the vertical portion 17c, thereby fixing the second connecting material 36 and the decorative material 17 together. (7) The second connecting member 36 is attached to the base frame 20. (8) Install the boards 12 in order. (9) When three or more panel bodies 11 are connected together, steps (4) to (8) are repeated. (10) After all the boards 12 have been installed, apply the joint material 18 to the top of the clearance C to fill the joint between the first connecting material 35 and the second connecting material 36. (11) Attach the base cover 23, lower base cover 31, base lid 25, tip lid 30, etc.

[0101] In this way, since attachment can be made not only from the plate material 12A side but also from the plate material 12B side, it is possible to adapt to the environment and conditions of the construction site, and workability is good.

[0102] In this embodiment, the decorative material 17 is attached to the second connecting material 36, but the decorative material 17 may also be attached to the first connecting material 35. That is, the target for attaching the decorative material 17 needs only to have a wall portion to which the vertical portion 17c of the decorative material 17 can be fixed, so the vertical portion 17c of the decorative material 17 may be attached to the vertical wall portion 35a of the first connecting material. In this case, the decorative material 17 can be used by rotating it horizontally 180 degrees from the state shown in FIG. 11.

[0103] It is also possible to use a combination of the plate material 12A and first connecting material 15 (see FIG. 3(a)) according to the first embodiment and the plate material 12B and second connecting material 36 (see FIG. 11(a)) according to the second embodiment. In this case, the first connecting material 15 and the second connecting material 36 are arranged on either side of the clearance C. In this configuration, the first connecting material 15 and the second connecting material 36 both have vertical wall portions 15a, 36a formed thereon, so the decorative material 17 can be attached to either of the vertical wall portions 15a, 36a. Regardless of which vertical wall portion 15a, 36a the decorative material 17 is attached to, the clearance C can be covered.

[0104] In this embodiment, multiple panel bodies 11 can be connected together in this manner, with a clearance C provided at the connection. The decorative material 17 that covers this clearance C is fixed only to one of the connecting members (the second connecting member 36) as shown in FIG. 14(a), and is not fixed to the other connecting member (the first connecting member 35). This allows the width of the clearance C to be adjusted. Specifically, as shown in FIG. 14(b), the clearance C can be minimized to a position where the first connecting member 35 and the second connecting member 36 interfere with each other. Furthermore, as shown in FIG. 14(c), the clearance C can be maximized to a position where the decorative material 17 can cover the first connecting member 35 and the second connecting member 36. In the above embodiment, the panel structure 10 is used for a building eaves whose tip end slopes downward, but the present invention is not limited to this.

[0105] For example, the panel structure 10 may be used for a building eave whose tip end slopes upward. In this case, a horizontal gutter 68 and a vertical gutter 69 may be provided at the end of the panel structure 10 on the wall surface 80 side. Also, as shown in FIG. 15, the panel structure 10 may be used for a suspended roof supported by beams 70.

[0106] In the above embodiment, the panel structure 10 is used as a building canopy, but the panel structure 10 may be used for other purposes. For example, the panel structure 10 may be used on a horizontal roof or a vertical wall.

[0107] (summary) As described above, according to this embodiment, the panel body 11 comprises a plurality of plate materials 12 joined in the width direction W and connecting materials attached to the ends of the panel body 11 in the width direction W, and an adjustment clearance C can be formed between adjacent connecting materials, and a decorative material 17 is attached to at least one surface of the panel body 11 so as to cover the adjacent connecting materials and the clearance C.

[0108] With this configuration, the connecting material and clearance C, where an observer may notice color unevenness, can be covered with decorative material 17. This reduces the problem of color unevenness caused by differences in the shapes of the components.

[0109] Furthermore, the decorative material 17 has a horizontal portion 17a that covers the surface of the panel body 11 and a vertical portion 17c that protrudes perpendicularly from the horizontal portion 17a, and the vertical portion 17c is fixed to one of the adjacent connecting materials. With this configuration, the fasteners 19 for attaching the decorative material 17 are not exposed on the surface, resulting in good design. Furthermore, because the decorative material 17 is fixed only to one of the adjacent connecting materials, the width of the clearance C can be adjusted.

[0110] Furthermore, when the panel body 11 is viewed in the thickness direction, the horizontal portion 17a protrudes from the surface of the panel body 11. This configuration makes the difference in color tone between the panel body 11 and the decorative material 17 less noticeable, since the difference in color tone is unlikely to be perceived as color unevenness. Specifically, because the board material 12 and the decorative material 17 have different shapes, differences in the optical properties (different color tones) between the two may occur. In this regard, by intentionally not arranging the decorative material 17 and the panel body 11 on the same plane, even if there is a difference in color tone between the two, the difference is difficult for the observer to perceive because the difference in color tone is caused by differences in the light source and the observer's position relative to the components (it is impossible to determine whether the difference is due to the color tone of the components themselves or the observation position, etc.). Therefore, even if there is a difference in color tone, the observer does not perceive it as unnatural color unevenness, thereby minimizing the impact on the design.

[0111] Furthermore, the decorative material 17 has bent portions 17b at both ends of the horizontal portion 17a, and the bent portions 17b extend so as to approach the surface of the panel body 11 as they approach their tips. This configuration allows the panel body 11 and the horizontal portion 17a to be connected by the bent portions 17b, resulting in a good design. In particular, in this embodiment, the stepped portions formed by the bent portions 17b are intentionally made with different patterns to give different impressions to the viewer. This allows the bent portions 17b to form a "switching pattern," making it possible to utilize the difference in color tone as part of the design. Furthermore, by not connecting the panel body 11 and the horizontal portion 17a, any difference in color tone between the two is less likely to be perceived as an unnatural color unevenness, improving the design.

[0112] Furthermore, by providing the bent portions 17b, a gutter shape is formed between the bent portions 17b. Therefore, when the decorative material 17 is placed below the panel body 11, water that has entered through the clearance C or the like can be received in the gutter shape.

[0113] Furthermore, vertical portion 17c has a plurality of protrusions 17d formed on the surface that is fixed to the connecting material. Providing these protrusions 17d allows burrs and chips that are generated when fastener 19 is attached to escape into the gaps. This prevents problems during installation caused by burrs and chips.

[0114] Furthermore, the panel body 11 is placed with the surface to which the decorative material 17 is attached facing downward, and the plate material 12 and the connecting material are joined either without using fasteners 19 or with fasteners 19 attached from the underside. That is, in the example shown in FIG. 3, the plate material 12A and the first connecting material 15 are joined without using fasteners 19, and the plate material 12B and the second connecting material 16 are joined with fasteners 19 attached from the underside. In the example shown in FIG. 11, the plate material 12A and the first connecting material 35 are joined with fasteners 19 attached from the underside, and the plate material 12B and the second connecting material 36 are joined without using fasteners 19. With this configuration, since fasteners 19 are not used on the upper side, water is prevented from entering through holes in the fasteners 19 and water is prevented from draining from unexpected locations.

[0115] Furthermore, at least one of the adjacent connecting members has an inclined portion 52c extending obliquely downward from the boundary with the plate 12 on the upper surface, and the inclined portion 52c is inclined in a direction away from the plate 12. That is, in the example shown in FIG. 3, the first connecting member 15 has an inclined portion 52c extending obliquely downward from the boundary 15b with the plate 12 on the upper surface, and the inclined portion 52c is inclined in a direction away from the plate 12. In the example shown in FIG. 11, the first connecting member 35 has an inclined portion 52c extending obliquely downward from the boundary 35b with the plate 12 on the upper surface, and the inclined portion 52c is inclined in a direction away from the plate 12. With this configuration, water that seeps in from the boundaries 15b, 35b can be guided obliquely downward along the inclined portion 52c, thereby increasing the capacity to receive rainwater and the like that has seeped in. In addition, in the example shown in FIG. 11, water can be prevented from entering in the direction of the fastener 19 that fixes the first connecting material 35.

[0116] The connecting member is covered with the decorative material 17 and is therefore not visible to the observer, but the surface of this connecting member may be given the same processing (for example, an irregular wood grain pattern) as the board material 12. With this configuration, even if the connecting member becomes visible due to an excessively large clearance C, the same pattern as the panel body 11 will reduce the sense of incongruity in appearance.

[0117] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. For example, embodiments obtained by appropriately combining the technical means disclosed in different embodiments and modifications are also included in the technical scope of the present invention.
