Description

[Technical Field]

[0001] The present invention relates to a wall structure constructed by providing frame members on the edges of surface material units. [Background technology]

[0002] In wall structures such as gate sleeves that use panel units, accommodation grooves are formed in the visible surfaces of frame materials such as posts and frames, and the panel units are supported by fitting the edges of the panel units into the accommodation grooves. The accommodation grooves are configured to have a width greater than the thickness of the panel units. Gaskets or sealing materials are placed in the gaps between the panel units and the accommodation grooves (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-74274 Summary of the Invention [Problem to be solved by the invention]

[0004] However, surface material units are not necessarily made of a single surface material, and some are made by bonding multiple surface materials together to meet various requirements. For example, the one described in Patent Document 1 improves its strength by bonding two glass plates together. Furthermore, as a surface material unit that takes design into consideration, there is also provided one in which a decorative surface material, such as a stone panel made by slicing natural stone, is bonded to the surface of a base metal panel.

[0005] Here, for a panel unit made by bonding two glass sheets together, the surfaces of each can be made smooth, making it easy to support it on a frame material via a receiving groove. However, for panel units using decorative panel materials such as stone panels, the relatively large irregularities on the surface often enhance the design. This inevitably results in uneven panel thickness, and even if a gasket or sealant is inserted between the panel and the frame material, it is difficult to fill the gap between the panel unit and the surface, raising concerns about unstable support of the panel unit.

[0006] In view of the above circumstances, an object of the present invention is to provide a wall structure that stably supports a surface material unit regardless of the surface condition of the decorative surface material. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the wall structure of the present invention is a wall structure in which a frame material is provided on the edge of a surface material unit, the frame material having an accommodation groove on the visible surface, the surface material unit comprising a base surface material and a decorative surface material provided to cover the surface of the base surface material except for the edge portion, and the edge portion of the decorative surface material is supported on the frame material via the base surface material with the decorative surface material accommodated in the accommodation groove. [Effects of the Invention]

[0008] According to the present invention, since the panel unit is supported on the frame material via the base panel, the panel unit can be stably supported regardless of the surface condition of the decorative panel. Moreover, since the edge of the decorative panel is accommodated in the accommodation groove, it is possible to prevent the design from being impaired or the panel unit from peeling off from the base panel.

[0010] A preferred embodiment of a wall structure according to the present invention will be described in detail below with reference to the accompanying drawings. For convenience, the terms "prospect direction" and "visibility direction" will be used below. The prospect direction is the direction along the depth of the wall structure, as indicated by arrow A in the drawings. A surface along the prospect direction will be referred to as a "visibility face." The prospect direction is the vertical direction perpendicular to the prospect direction in the case of horizontal frame members and other elements that extend horizontally. In the case of vertical frame members and other elements that extend vertically, the horizontal direction perpendicular to the prospect direction is referred to as the "visibility direction." A surface along the prospect direction will be referred to as a "visibility face."

[0011] 1 to 3 show a wall structure according to an embodiment of the present invention. The wall structure illustrated here is applied to an outdoor structure known as a gate sleeve and includes a panel unit 10 and a frame 20. The panel unit 10 is configured with a base panel 11, which is a rectangular plate with flat opposite surfaces, and decorative panel members 12 attached to both opposite surfaces of the base panel 11 with an adhesive such as double-sided tape. The decorative panel member 12 is rectangular and smaller than the base panel member 11. It is disposed in the center of the base panel member 11, with all four peripheral edge surfaces of the base panel member 11 exposed to the outside. Although not shown in the figures, the base panel member 11 is configured by laminating thin aluminum alloy plates to both opposite surfaces of a resin plate. The decorative panel members 12 are configured by laminating a reinforcing resin material such as FRP to one surface of a stone panel made by slicing natural stone, and are attached to the base panel member 11 with the stone panel exposed to the surface.

[0012] The frame body 20 is provided with an upper frame (frame material) 23 and a lower frame (frame material) 24 between left and right vertical frames (frame materials) 21, 22, and is framed on all four sides to define a rectangular opening 25 between them that is smaller than the decorative surface material 12. In this embodiment, the vertical frames 21, 22 are used, which have a length greater than the vertical dimensions of the surface material unit 10, and the lower frame 24 is provided at a portion of the vertical frames 21, 22 above the position where they are buried in the ground E. In addition, the left and right vertical frames 21, 22 are sized to protrude above the upper frame 23, and the upper end faces of each are connected by a coping 26.

[0013] As shown in Figure 4, the vertical frame on the right side when viewed from the front side (hereinafter referred to as the right vertical frame 21) is configured to include a right vertical frame main body (frame main body) 31 and a right vertical frame cover member 32. The right vertical frame main body 31 and the right vertical frame cover member 32 are extruded shapes formed from a metal such as an aluminum alloy, and each is configured to have a uniform cross-sectional shape along its length.

[0014] The right vertical frame body 31 has a generally rectangular cross section and a cylindrical shape. Its inner peripheral surface 31a is provided with a right cover mounting recess 31b and a groove-forming recess 31c. The right cover mounting recess 31b is for detachably mounting the right vertical frame cover member 32 (described later). The front and rear edges of the right cover mounting recess 31b are each provided with an engagement receiving portion 31d. The groove-forming recess 31c is formed in a portion of the front surface 31a of the right vertical frame body 31 that is closer to the front than the right cover mounting recess 31b. When the right vertical frame cover member 32 is mounted in the right cover mounting recess 31b, it forms a storage groove 33 that opens to the inner peripheral side between the right vertical frame body 31 and the right vertical frame body 31. The groove-forming recess 31c is provided with a bead mounting portion 31e and a bead engagement portion 31f. A pair of bead mounting portions 31e are provided on the left and right sides of the front side of the groove-forming recess 31c in the portion extending in the viewing direction, and a bead (clamping member) 40 can be mounted between them. The bead engaging portion 31f is provided in a position opposite the bead mounting portion 31e and can hold a bead (clamping member) 41 inserted from the inner periphery side. As is clear from the figure, the bead mounting portion 31e and the bead engaging portion 31f are provided in positions that are approximately in the middle of the storage groove 33 so that the beads 40, 41 are positioned at a distance from the projected surface 31a, which is the inner periphery side of the right vertical frame body 31, to the outer periphery side.

[0015] The right vertical frame cover member 32 has engagement wall portions 32b extending in the same direction on both sides of a flat, projecting wall portion 32a. Engagement claws 32c are provided on the extending edges of the engagement wall portions 32b. The right vertical frame cover member 32 can be detachably attached to the right vertical frame main body 31 by engaging the engagement claws 32c with the engagement receiving portions 31d. When the right vertical frame cover member 32 is attached to the right vertical frame main body 31, the surface of the projecting wall portion 32a is positioned on approximately the same plane as the projecting surface 31a of the right vertical frame main body 31. Furthermore, between the groove-forming recess 31c of the right vertical frame main body 31 and the right vertical frame cover member 32, a storage groove 33 is formed, the opening width of which can accommodate the base surface material 11 of the surface material unit 10 and the decorative surface materials 12 provided on both surfaces of the base surface material 11.

[0016] As shown in Figure 5, the upper frame 23 is configured to include an upper frame body (frame body) 51 and an upper frame cover member 52, and as shown in Figure 6, the lower frame 24 is configured to include a lower frame body (frame body) 61 and a lower frame cover member 62. The upper frame body 51, upper frame cover member 52, lower frame body 61, and lower frame cover member 62 are extruded shapes formed from metal such as aluminum alloy, and each is configured to have a uniform cross-sectional shape along its length.

[0017] As shown in FIG. 5, the upper frame body 51 has a groove-forming wall 51b integrally formed on the front side of the upper frame hollow 51a, which has a generally rectangular cross section. The upper frame hollow 51a is formed so that its dimensions along the projection direction are approximately the same as those of the upper frame cover member 52 (described later), and has an engagement receiving portion 51c on its inner projection surface. The groove-forming wall 51b is a thin plate that extends from an outer corner of the upper frame hollow 51a toward the front side and then bends toward the inner side at a substantially right angle, forming a groove-forming recess 51d that opens toward the inner side between the upper frame hollow 51a and the upper frame hollow 51a. The portion of the groove-forming wall 51b that extends toward the inner side protrudes beyond the projection surface of the upper frame hollow 51a, which is the inner side of the upper frame hollow 51a. The groove-forming recess 51d is provided with a bead mounting portion 51e and a bead engagement portion 51f. The bead mounting portions 51e are a pair of upper and lower bead mounting portions provided on the groove forming wall portion 51b in a portion extending inwardly, and can mount the bead 40 between them. The bead engaging portion 51f is provided in a position facing the bead mounting portion 51e, and can hold the bead 41 inserted from the inner circumferential side. As is clear from the figure, the bead mounting portion 51e and the bead engaging portion 51f are provided in positions that are approximately midway along the portion extending inwardly of the groove forming wall portion 51b, so that the beads 40, 41 are positioned at a distance from the extending edge of the groove forming wall portion 51b toward the outer circumferential side.

[0018] The upper frame cover member 52 has engagement walls 52b extending in the same direction on both sides of a flat projection wall 52a so as to have the same cross-sectional shape as the right vertical frame cover member 32, and can be detachably attached to the upper frame main body 51 by engaging the engagement claws 52c of the engagement wall 52b with the engagement receiving portions 51c. When the upper frame cover member 52 is attached to the upper frame main body 51, the surface of the projection wall 52a is positioned on approximately the same plane as the extending edge of the groove-forming wall 51b, forming a projection surface 23a that forms the inner peripheral side of the upper frame 23. In addition, between the groove-forming wall 51b of the upper frame main body 51 and the upper frame cover member 52, an accommodation groove 53 having the same dimensions as the accommodation groove 33 provided in the right vertical frame 21 is formed so as to be continuous with the accommodation groove 33 provided in the right vertical frame 21.

[0019] As shown in FIG. 6, the lower frame body 61 has a groove-forming wall 61b integrally formed on the front side of a lower frame hollow 61a, which has a generally rectangular cross section. The lower frame hollow 61a is formed so that its dimensions along the projection direction are approximately the same as those of the upper frame body 51, and has an engagement receiving portion 61c on its inner projection surface. The groove-forming wall 61b has a first wall 61b1 extending from an inner corner of the lower frame hollow 61a toward the inner side, and a second wall 61b2 extending approximately horizontally toward the rear from a portion approximately midway in the height direction on the rear surface of the first wall 61b1. The first wall 61b1 also has a bead mounting portion 61d on the inner side of the second wall 61b2. The bead mounting portion 61d is a pair of upper and lower bead mounting portions provided on the first wall 61b1, and a bead 40 can be mounted between them. As can be seen from the figure, the bead mounting portion 61d is located approximately midway between the extending edge of the first wall body 61b1 and the second wall body 61b2 so that the bead 40 is positioned at a distance from the extending edge of the first wall body 61b1 toward the outer periphery.

[0020] The lower frame cover member 62 has engaging claws 62b at each of the outer corners of the lower cover hollow portion 62a, which has a trapezoidal cross section. The engaging claws 62b engage with the engaging receptacles 61c, allowing the lower frame cover member 62 to be detachably attached to the lower frame main body 61. When the lower frame cover member 62 is attached to the lower frame main body 61, the inner circumferential surface of the lower cover hollow portion 62a becomes the visible surface 24a of the lower frame 24 and is positioned approximately flush with the extended edge of the groove-forming wall portion 61b provided on the lower frame main body 61. The front surface of the lower cover hollow portion 62a is approximately parallel to the groove-forming wall portion 61b, with a gap between them, thereby forming a storage groove 63 between the groove-forming wall portion 61b and the lower cover hollow portion 62a. The storage groove 63 has the same dimensions as the storage groove 33 provided in the right vertical frame 21 and is positioned contiguous to the storage groove 33. In the lower cover hollow portion 62a, a bead mounting portion 62c having the same configuration as the bead mounting portion 61d of the lower frame main body 61 is provided in a portion facing the bead mounting portion 61d, and the bead 40 can be mounted thereon.

[0021] On the other hand, the vertical frame on the left side when viewed from the front side (hereinafter referred to as left vertical frame 22) is configured to include a left vertical frame main body (frame main body) 71 and a left vertical frame cover member 72, as well as an auxiliary vertical frame main body 73, a front plate 74, and a rear plate 75, as shown in Figure 7. The left vertical frame main body 71, left vertical frame cover member 72, auxiliary vertical frame main body 73, front plate 74, and rear plate 75 are extruded shapes formed from metal such as aluminum alloy, and each is configured to have a uniform cross-sectional shape along its length.

[0022] The left vertical frame body 71 has a groove-forming wall portion 71b integrally formed in the front portion of the left vertical frame hollow portion 71a, which has an irregular cylindrical cross section. The cross-sectional shape of the left vertical frame hollow portion 71a is described in detail below. The left vertical frame hollow portion 71a has an outer peripheral wall portion 71a1, a front wall portion 71a2 extending from the front edge of the outer peripheral wall portion 71a1 toward the inner periphery, a rear wall portion 71a3 extending from the rear edge of the outer peripheral wall portion 71a1 toward the inner periphery, and an inner peripheral wall portion 71a4 extending from the inner peripheral edge of the rear wall portion 71a3 toward the front side. The front wall portion 71a2 is shorter than the rear wall portion 71a3, and the inner peripheral wall portion 71a4 is shorter than the outer peripheral wall portion 71a1. The inner peripheral edge of the front wall 71a2 is provided with a middle recessed wall 71a5 facing the rear, and the front edge of the inner recessed wall 71a4 is provided with a middle recessed wall 71a6 that extends toward the outer periphery and connects to the extended edge of the middle recessed wall 71a5. That is, by providing the middle recessed wall 71a5 and the middle recessed wall 71a6 between the front wall 71a2 and the inner recessed wall 71a4, a left cover mounting recess 71c is formed in the left vertical frame body 71. The left cover mounting recess 71c is for detachably mounting the left vertical frame cover member 72, which will be described later. The left cover mounting recess 71c is provided with engagement receiving portions 71d on the front and rear edges, respectively.

[0023] The groove-forming wall portion 71b is a thin plate-like member that extends from the outer corner of the left vertical frame hollow portion 71a toward the front surface and then bends toward the inner periphery at a substantially right angle. This thin plate defines a groove-forming recess 71e that opens toward the inner periphery between the left vertical frame hollow portion 71a and the left vertical frame hollow portion 71a. The portion of the groove-forming wall portion 71b that extends toward the inner periphery protrudes more inward than the intermediate projection wall portion 71a5 of the left vertical frame hollow portion 71a and is positioned outward from the projection surface of the inner projection wall portion 71a4 by the thickness of the front plate 74 (described later). The groove-forming recess 71e is provided with a bead mounting portion 71f and a bead engagement portion 71g. The bead mounting portions 71f are a pair of left and right bead mounting portions provided on the inner-extending portion of the groove-forming wall portion 71b, and a bead 40 can be mounted between them. The bead engaging portion 71g is provided at a position opposite the bead mounting portion 71f and is capable of holding the bead 41 inserted from the inner peripheral side. As is clear from the figure, the bead mounting portion 71f and the bead engaging portion 71g are provided at positions that are approximately midway along the inner peripheral extending portion of the groove forming wall portion 71b so that the beads 40, 41 are positioned at a distance from the extending edge of the groove forming wall portion 71b toward the outer peripheral side.

[0024] The left vertical frame cover member 72 has engagement walls 72b extending in the same direction on both sides of a flat projection wall 72a so as to have the same cross-sectional shape as the right vertical frame cover member 32. The left vertical frame cover member 72 can be detachably attached to the left vertical frame main body 71 by engaging the engagement claws 72c of the engagement wall 72b with the engagement receiving portions 71d. When the left vertical frame cover member 72 is attached to the left vertical frame main body 71, the surface of the projection wall 72a is positioned on approximately the same plane as the projection surface of the inner projection wall portion 71a4, and each forms the projection surface 22a that is on the inner periphery of the left vertical frame 22. In addition, between the groove-forming recess 71e of the left vertical frame main body 71 and the left vertical frame cover member 72, a storage groove 76 is formed that has the same dimensions as the storage grooves 33, 63 provided in the right vertical frame 21 and the bottom frame 24 so as to be continuous with each other.

[0025] The auxiliary vertical frame body 73 is a cylindrical body with a roughly rectangular cross section, configured so that its dimensions in the front and rear directions are approximately the same as those of the left vertical frame body 71. The front plate 74 and rear plate 75 connect the front and rear of the left vertical frame body 71 and the auxiliary vertical frame body 73 when they are arranged side by side with a gap between them. The front plate 74 has a flat plate-shaped plate body 74a with thin plate-like cover walls 74b bent toward the rear on both side edges of the plate body 74a. Connecting walls 74c are provided on the rear surface of the plate body 74a at positions spaced apart from the cover walls 74b. The front plate 74 is attached to the left vertical frame body 71 and the auxiliary vertical frame body 73 such that the inner peripheral cover wall 74b covers the inner peripherally extending edge of the groove-forming wall 71b on the left vertical frame body 71, and the outer peripheral cover wall 74b is substantially flush with the outer peripheral surface of the auxiliary vertical frame body 73. The front plate 74 is connected to the left vertical frame body 71 and the auxiliary vertical frame body 73 by attaching brackets 77 with L-shaped cross sections to opposing portions of the left vertical frame body 71 and the auxiliary vertical frame body 73, and then threading screws between the brackets 77 and the connecting wall 74c and between the brackets 77 and the left vertical frame body 71 and the auxiliary vertical frame body 73. The rear plate 75 is substantially flat and is attached to the rear surface of the left vertical frame body 71 and the rear surface of the auxiliary vertical frame body 73. The reference numeral 78 in the drawing denotes a rear cover for covering the screws threaded into the left vertical frame body and the auxiliary vertical frame body 73 via the rear plate 75. The front plate 74 and the rear plate 75 are provided only on the part of the gate sleeve that is above the ground E.

[0026] The left and right vertical frames 21, 22, the upper frame 23 and the lower frame 24 having the above-described configuration are fitted with the beads 40, 41 in advance in the respective bead mounting portions 31e, 51e, 61d, 62c, 71f and the bead engaging portions 31f, 51f, 71g, respectively, and then fitted into the respective accommodation grooves 33, 53, 63, 76. By attaching the upper frame 23 and the lower frame 24 to the four sides of the panel unit 10 via the panels and connecting both ends of the upper frame 23 and the lower frame 24 to the vertical frames 21 and 22, respectively, a frame body 20 is formed in which the opening 25 is blocked by the panel unit 10, i.e., the wall structure of the gate sleeve.

[0027] Here, in the face material unit 10, the dimension of the base face material 11 along the left and right is set to be larger than the spacing between the beads 40 attached to the left and right vertical frames 21, 22, and the dimension of the base face material 11 along the top and bottom is set to be larger than the spacing between the beads 40 attached to the upper frame 23 and the lower frame 24. In contrast, the dimension of the decorative face material 12 along the left and right is set to be smaller than the spacing between the beads 40 attached to the left and right vertical frames 21, 22, and the dimension along the top and bottom is set to be smaller than the spacing between the beads 40 attached to the upper frame 23 and the lower frame 24. Furthermore, the dimension of the decorative face material 12 along the left and right is set to be larger than the spacing between the visible surfaces 31a, 22a on the inner periphery side of the vertical frames 21, 22, and the dimension along the top and bottom is set to be larger than the spacing between the visible surfaces 23a, 24a on the inner periphery side of the upper frame 23 and the lower frame 24.

[0028] As a result, the decorative surface material 12 of the surface material unit 10 is positioned more inward than the beads 40, 41, and the edges of the base surface material 11 protruding from the decorative surface material 12 are sandwiched between the beads 40, 41 and between the beads 40 themselves. Therefore, even when a stone panel with large irregularities is used as the decorative surface material 12, the beads 40, 41 are in full contact with the flat surface of the base surface material 11, enabling stable support of the surface material unit 10. Moreover, the edges of the decorative surface material 12 on all four sides are accommodated in the accommodation grooves 33, 53, 63, 76, so the boundary with the base surface material 11 is not exposed to the outside of the frame 20. This eliminates concerns about impairing the design of the gate sleeve and prevents the decorative surface material 12 from peeling off from the base surface material 11.

[0029] In the gate sleeve configured as described above, the opening edge located on the rear side of the storage groove 33, 76 of the vertical frames 21, 22 is formed by the vertical frame cover member 32, 72 that is detachable from the vertical frame main body 31, 71, and the opening edge located on the rear side of the storage groove 63 of the bottom frame 24 is formed by the bottom frame cover member 62 that is detachable from the bottom frame main body 61. Therefore, as shown in Figure 8, the storage groove 33, 76 can be opened by removing the vertical frame cover member 32, 72 from the vertical frame main body 31, 71 and then removing the bead 41 attached to the bead engagement portion 31f, 71g. Similarly, the storage groove 63 can be opened by removing the bottom frame cover member 62 from the bottom frame main body 61. As a result, when performing maintenance such as replacing the surface material unit 10, by removing the top board 26 and upper frame 23 and opening the storage grooves 33, 76 of the vertical frames 21, 22 and the storage groove 63 of the lower frame 24 as described above, the surface material unit 10 can be pulled out upward even when the lower ends of the vertical frames 21, 22 are buried in the ground, making it possible to easily carry out maintenance.

[0030] While the above-described embodiment illustrates a wall structure installed in a gate sleeve, it is not limited to a gate sleeve as long as frame members are installed around the edges of the panel unit. In this case, frame members do not necessarily need to be installed around the entire periphery of the panel unit; for example, frame members may be installed only around the top and bottom edges or the left and right edges of the panel unit. Furthermore, while the left vertical frame 22 is illustrated as including an auxiliary vertical frame body 73 and front and rear plates 74, 75, these are not necessarily required. Furthermore, while the panel unit 10 is supported via beads 40, 41, these beads 40, 41 are not necessarily required. Other fixed-shaped clamping members may be used, or the panel unit may be supported by filling it with a sealant.

[0031] Furthermore, in the above-described embodiment, the base surface material 11 of the surface material unit 10 is formed by laminating thin aluminum alloy plates on both side surfaces of a flat resin plate, and the decorative surface material 12 is formed by laminating a reinforcing resin material such as FRP on the back surface of a stone panel made by slicing natural stone, but the surface material unit of the present invention is not limited to these. Furthermore, it is not necessary to provide decorative surface materials 12 on both sides of the base surface material 11; it is sufficient if a decorative surface material is provided on at least one surface of the base surface material. Note that when decorative surface materials are provided on both sides of the base surface material, different decorative surface materials may be used.

[0032] Furthermore, as described above, the opening edge portion located on the rear side of the storage groove 33, 76 of the vertical frame 21, 22 is formed by a vertical frame cover member 32, 72 that is detachable from the vertical frame main body 31, 71, and the opening edge portion located on the rear side of the storage groove 63 of the lower frame 24 is formed by a lower frame cover member 62 that is detachable from the lower frame main body 61, but the present invention does not necessarily require the frame materials 21, 22, 24 to be equipped with cover members 32, 72, 62.

[0033] As described above, the wall structure of the present invention is a wall structure in which a frame material is provided on the edge of a surface material unit, the frame material having an accommodation groove on its visible surface, the surface material unit comprising a base surface material and a decorative surface material provided to cover the surface of the base surface material except for the edge, and the edge of the decorative surface material is supported on the frame material via the base surface material with the edge accommodated in the accommodation groove. According to this invention, since the panel unit is supported by the frame material via the base panel, the panel unit can be stably supported regardless of the surface condition of the decorative panel. Moreover, since the edge of the decorative panel is accommodated in the accommodation groove, it is possible to prevent the design from being damaged or the panel unit from peeling off from the base panel.

[0034] The present invention is also characterized in that, in the above-mentioned wall structure, clamping members are provided in opposing portions of the storage grooves of the frame material, and the edge of the base surface material of the surface material unit is clamped between the clamping members. According to this invention, there is no need to perform work such as filling a sealing material between the base surface material and the frame material, so that the work of supporting the surface material unit on the frame material can be easily performed.

[0035] The present invention is also characterized in that, in the above-mentioned wall structure, the clamping member is provided inside the accommodating groove at a position spaced apart from the visible surface of the frame material toward the outer periphery. According to this invention, it is possible to cover the edge of the decorative surface material widely, which has the advantage of more reliably preventing the decorative surface material from peeling off from the base surface material.

[0036] Furthermore, the present invention is characterized in that in the wall structure described above, the surface material unit has the decorative surface material provided on each of both side surfaces of the base surface material. According to this invention, a wall structure can be constructed in which both side surfaces of the surface material unit have design surfaces.

[0037] Furthermore, the present invention is characterized in that, in the wall structure described above, the surface material unit has a quadrangular shape, and the frame material is provided on at least two edge portions that are opposite sides. According to this invention, a panel frame can be supported between two frame members. The panel unit may be rectangular, or may be any other quadrangular shape such as a square, parallelogram, or trapezoid.

[0038] The present invention is also characterized in that, in the above-mentioned wall structure, the frame material comprises a frame main body and a cover member that is detachable from the frame main body, and at least one opening edge of the storage groove is formed by the cover member. According to this invention, the accommodation groove is opened by removing the cover member from the frame body, which makes it possible to facilitate the work when performing maintenance on the surface material unit.

[0039] The present invention is also characterized in that, in the above-mentioned wall structure, the projected surface of the frame material is arranged so that the portions on both sides of the storage groove are positioned on the same plane. According to this invention, even if the surface material unit is transparent, there is no risk of the inner surface of the storage groove being visible through the surface material unit. Note that the surface material unit does not necessarily have to be perfectly aligned on the same plane, and some deviation is acceptable. [Explanation of symbols]
