Description

The present invention relates to a decorative material having hollow members arranged in a longitudinal direction, and a curtain wall having a decorative material.

A decorative material having hollow members is attached to a curtain wall, for example, and installed on the wall of a building. The hollow members of the decorative material are arranged in a line in the longitudinal direction of the hollow members, and extend in the longitudinal direction of each member. Adjacent hollow members are connected to each other at their longitudinal ends. Regarding the connection between such hollow members, a connection structure for hollow members that uses a joint sleeve to connect hollow members is known in the past (see Patent Document 1).

In conventional decorative materials, adjacent hollow members are connected to each other by a joint sleeve disposed inside the hollow member, as in the hollow member connection structure described in Patent Document 1. However, depending on the design and function required of the decorative material, the structure of the end of the hollow member may be changed depending on the location, and a portion for connecting adjacent hollow members and a portion for fixing the lid material to the end of the hollow member may be provided. The lid material is fixed to, for example, a base material attached inside the hollow member. In this way, a fixing mechanism other than the joint sleeve is required to fix the lid material. This may complicate the structure of the decorative material, and may increase the effort required to manufacture the decorative material.

An embodiment of the decorative material and curtain wall of the present invention will be described with reference to the drawings.
The decorative material of the present embodiment is a decorative material for buildings, and is provided on the curtain wall of the present embodiment and installed on the wall of a building. The curtain wall is used on the exterior wall of a building and is installed between the interior (indoors) and exterior (outdoors) of the building.

Figure 1 is a front view of the curtain wall 1 of this embodiment, showing the curtain wall 1 installed on the wall portion 11 of a building 10 as viewed from the outside of the room. Figure 2 is a vertical cross-sectional view of the curtain wall 1 of this embodiment, showing a part of the building 10 and the curtain wall 1 cut along line X1-X1 in Figure 1. Figure 3 is a horizontal cross-sectional view of the curtain wall 1 of this embodiment, showing the curtain wall 1 cut along line X2-X2 in Figure 1.

As shown in the figure, the curtain wall 1 comprises a plurality of curtain wall units 2 arranged side by side on the wall 11 of the building 10, and decorative materials 3 attached to the curtain wall units 2. The curtain wall units 2 are panel units that make up the curtain wall 1, and are pre-assembled as units before installation on the wall 11. The curtain wall 1 and the curtain wall units 2 are disposed on the outdoor side of the building frame 12 of the building 10, and are attached to the frame 12 to form the wall surface (exterior wall surface) of the wall 11 of the building 10. The plurality of curtain wall units 2 are arranged side by side in the vertical and horizontal directions, and are combined with adjacent curtain wall units 2.

When the curtain wall 1 and decorative material 3 installed on the building 10 are viewed from the front (see Figure 1), the direction that is up and down is the up-down direction, and the direction that is left and right is the left-right direction. In Figure 1, the up-down direction is the vertical direction, and the left-right direction is the horizontal direction. The indoor/outdoor direction S (see Figures 2 and 3) is the indoor/outdoor direction (indoor/outdoor direction) of the curtain wall 1 and decorative material 3 installed on the building 10. In this way, the directions related to the curtain wall 1 and decorative material 3 are specified by the directions when installed on the building 10. Also, the indoor side and outdoor side of the curtain wall 1 and decorative material 3 are the indoor side and outdoor side when installed on the building 10.

The curtain wall unit 2 comprises panel bodies 2A and 2B and a frame body 4 surrounding the panel bodies 2A and 2B. The frame bodies 4 of the multiple curtain wall units 2 are each combined with the frame body 4 of the adjacent curtain wall unit 2. The frame body 4 is a rectangular opening frame that forms an opening, and is attached to the building frame 12 of the building 10. The panel bodies 2A and 2B are rectangular glass panel bodies (e.g., plate glass, double glazing, or laminated glass), and are each arranged in the opening of the frame body 4.

The frame body 4 has four interlocking frames 5 to 8 (upper frame 5, lower frame 6, and a pair of vertical frames 7, 8) and a lattice 9. The upper frame 5 and lower frame 6 are the upper and lower horizontal frames of the frame body 4, and extend in the left-right direction (horizontal direction) at the top and bottom of the frame body 4. The pair of vertical frames 7, 8 (first vertical frame 7, second vertical frame 8) are side frames located on the left and right sides of the frame body 4, and extend in the up-down direction (vertical direction) at the sides of the frame body 4. The upper frame 5, lower frame 6, and the left and right vertical frames 7, 8 are connected at their ends to form a frame for the frames 5 to 8. The lattice 9 extends in the left-right direction between the upper frame 5 and lower frame 6, and is connected to the left and right vertical frames 7, 8. The panel bodies 2A and 2B are each fitted into the frame body 4 and held by the frame body 4.

The decorative material 3 is an external decorative material provided on the outside of the building 10, and is disposed on the exterior side of the curtain wall unit 2 and attached to the curtain wall unit 2 by multiple brackets 20 (see Figures 2 and 3). The decorative material 3 is also a decorative body of the building 10 that extends in the vertical direction, and is used for decorating the building 10. The multiple decorative materials 3 are arranged parallel to each other, spaced apart in the left-right direction on the wall portion 11 of the building 10. The multiple brackets 20 are provided at intervals in the longitudinal direction (vertical direction) of the decorative material 3, and are each attached to the frame body 4 of the curtain wall unit 2. The decorative material 3 is attached to the brackets 20, and is attached to the frame body 4 of the curtain wall unit 2 by the brackets 20, which are mounting materials.

FIG. 4 is a vertical cross-sectional view of the curtain wall 1 of this embodiment, showing an enlarged portion of FIG. 2, and FIG. 5 is a horizontal cross-sectional view of the curtain wall 1 of this embodiment, showing an enlarged portion of FIG.
As shown in the figure, in two vertically adjacent curtain wall units 2 (see FIG. 4), the lower frame 6 of the upper curtain wall unit 2 and the upper frame 5 of the lower curtain wall unit 2 are arranged adjacent to each other in the vertical direction, facing each other in the vertical direction. Also, in two horizontally adjacent curtain wall units 2 (see FIG. 5), the first vertical frame 7 of one curtain wall unit 2 and the second vertical frame 8 of the other curtain wall unit 2 are arranged adjacent to each other in the horizontal direction, facing each other in the horizontal direction.

The first vertical frame 7 is one of the pair of vertical frames 7, 8 of the frame body 4 and is located on one side in the left-right direction. The second vertical frame 8 is the other of the pair of vertical frames 7, 8 of the frame body 4 and is located on the other side in the left-right direction. The bracket 20 has an attachment portion 21 to which the decorative material 3 is attached, is attached to the first vertical frame 7, and protrudes from the first vertical frame 7 to the outside of the room. The attachment portion 21 is provided at the tip of the bracket 20 on the outside of the room and protrudes on both sides in the left-right direction. The decorative material 3 is attached to the attachment portion 21 of the bracket 20 by a bolt 22 and a back plate 23, which are mounting fixtures.

The decorative material 3 includes a hollow member 30 made of a shaped material formed into a hollow shape. The hollow member 30 is a decorative material body having a hollow portion 31, and has a groove-shaped engagement portion 32 located on the indoor side (the curtain wall unit 2 side). The engagement portion 32 is an engagement groove that extends in the longitudinal direction of the hollow member 30 and is open toward the indoor side. The engagement portion 32 is positioned opposite the first vertical frame 7 of the curtain wall unit 2 in the indoor/outdoor direction S, and accommodates the mounting portion 21 of the bracket 20.

The mounting portion 21 of the bracket 20 fits inside the engaging portion 32 and engages with the engaging portion 32. The back plate 23 is disposed within the hollow portion 31 of the hollow member 30 and is provided on the outdoor side of the engaging portion 32. In this state, the bolt 22 penetrates the mounting portion 21 and the hollow member 30 from the indoor side and is attached to the screw hole of the back plate 23. The hollow member 30 is attached to the mounting portion 21 of the bracket 20 by the bolt 22 and the back plate 23, and is attached to the curtain wall unit 2 (here, the first vertical frame 7 of the frame body 4) by the bracket 20. The hollow member 30 and the decorative material 3 protrude from the bracket 20 toward the outdoor side.

The hollow member 30 is a shaped member (extruded shaped member) formed by extrusion molding, and extends in the longitudinal direction (up-down direction) with the longitudinal direction facing the up-down direction. The multiple hollow members 30 are arranged in sequence in the longitudinal direction of the hollow members 30 with gaps between them. The hollow members 30 adjacent to each other in the longitudinal direction of the hollow members 30 (the longitudinal direction of the decorative material 3) are arranged at a distance in the longitudinal direction of the hollow members 30. The hollow members 30 and the decorative material 3 are arranged on the exterior side of the first vertical frame 7 of each of the multiple curtain wall units 2 arranged in the vertical direction, and extend along the first vertical frame 7. In addition, the hollow members 30 and the decorative material 3 are arranged on the exterior side of the first vertical frame 7 and the second vertical frame 8, spaced from the adjacent first vertical frame 7 and second vertical frame 8 of the curtain wall units 2 adjacent to each other in the left-right direction.

The end 33 of the hollow member 30 is a portion located at one end and the other end of the hollow member 30 in the longitudinal direction, and includes an end face 34 in the longitudinal direction of the hollow member 30. The end face 34 of the hollow member 30 is formed to intersect with the longitudinal direction of the hollow member 30. In two hollow members 30 adjacent to each other in the longitudinal direction of the hollow member 30, the end 33 of the two hollow members 30 face each other with a gap, and the end faces 34 of the two hollow members 30 face each other with a gap. In addition, the hollow portions 31 of the two hollow members 30 face each other with a gap, and each opens toward the other side. The structure (end structure) of the end 33 of the three types of hollow members 30 provided in the decorative material 3 will be described below.

Figure 6 is a perspective view showing the end structure 41 of the first hollow member 30 provided in the decorative material 3 of this embodiment, showing the portion on the end 33 side of the two hollow members 30. Figure 6A shows the end structure 41 of the first hollow member 30 in an exploded view, and Figure 6B shows the end structure 41 of the first hollow member 30 with a see-through view of the inside of the hollow member 30. Figure 7 is a side view showing the end structure 41 of the first hollow member 30 provided in the decorative material 3 of this embodiment, showing a see-through view of the inside of the hollow member 30. Figure 8 is a cross-sectional view showing the end structure 41 of the first hollow member 30 provided in the decorative material 3 of this embodiment, showing a cross-section taken along line X3-X3 in Figure 7.

As shown in the figure, the decorative material 3 includes a tubular connecting member 50 that connects two hollow members 30 together. The connecting member 50 is made of a hollow shaped member and is provided at a location where two adjacent hollow members 30 in the longitudinal direction of the hollow members 30 are connected (a connecting location between the hollow members 30). The connecting member 50 is disposed inside each of the two hollow members 30 to connect the two hollow members 30. The connecting member 50 is disposed from the inside of one of the two hollow members 30 to the inside of the other hollow member 30, and is provided in the gap between the two hollow members 30. At the connecting location between the hollow members 30, the connecting member 50 is disposed inside the hollow portion 31 of the two hollow members 30, and the end portions 33 of the two hollow members 30 are connected by the connecting member 50.

The connecting material 50 is inserted into the hollow member 30 (inside the hollow portion 31) from the opening at the end 33 of the hollow member 30, and is positioned along the inner surface of the hollow member 30. The connecting material 50 also has a number of protrusions 51 (see FIG. 8) that are distributed over the entire outer surface of the connecting material 50. The multiple protrusions 51 protrude outward from the connecting material 50 and each abut against the inner surface of the hollow member 30. The connecting material 50 is fitted into the hollow member 30 by the multiple protrusions 51, and engages with the hollow member 30.

The connecting material 50 is attached to at least one of the two hollow members 30 (either one of the hollow members 30 or both of the hollow members 30) by means of a screw 60 and a back plate 61 (see Figures 7 and 8). Here, the connecting material 50 is attached to one (upper) hollow member 30. The connecting material 50 has a plate-shaped attachment portion 52 located on the indoor side (the curtain wall unit 2 side). The attachment portion 52 of the connecting material 50 is located within the hollow member 30, on the indoor side of the engagement portion 32 of the hollow member 30.

The back plate 61 is disposed inside the connecting material 50 and is provided on the exterior side of the mounting portion 52. The screw 60 is a countersunk screw, which penetrates the hollow member 30 and the mounting portion 52 of the connecting material 50 from the interior side and is attached to the screw hole of the back plate 61. The mounting portion 52 of the connecting material 50 is sandwiched between the hollow member 30 and the back plate 61 and is attached to the hollow member 30 by the screw 60 and the back plate 61. In this way, the connecting material 50 is attached to the end 33 of the hollow member 30. The connecting material 50 is inserted into the other (lower) hollow member 30 while attached to one (upper) hollow member 30, and is disposed inside the other hollow member 30. The two hollow members 30 are connected to each other with a gap between them by the connecting material 50.

Figure 9 is a perspective view showing the end structure 42 of the second hollow member 30 provided in the decorative material 3 of this embodiment, showing the part on the end 33 side of the hollow member 30. Figure 9A shows the end structure 42 of the second hollow member 30 in an exploded view, and Figure 9B shows the end structure 42 of the second hollow member 30 with the inside of the hollow member 30 seen through. In Figure 9B, the end structure 42 of the upper hollow member 30 of the end structures 42 of the upper and lower hollow members 30 is shown by a two-dot chain line. Figure 10 is a side view showing the end structure 42 of the second hollow member 30 provided in the decorative material 3 of this embodiment, showing the inside of the hollow member 30 seen through. Figure 11 is a plan view showing the end structure 42 of the second hollow member 30 provided in the decorative material 3 of this embodiment, showing the end structure 42 of the second hollow member 30 as seen from the direction of the arrow X4 in Figure 10.

As shown in the figure, the decorative material 3 includes a plate-shaped lid material 70 that covers the opening of the end 33 of the hollow member 30 (hollow portion 31), and a cylindrical fixing material 80 held by the hollow member 30. The lid material 70 is a small end cap provided on the small end of the end 33 of the hollow member 30, and covers a part or the entire opening of the end 33 of the hollow member 30. The fixing material 80 is made of a shaped material formed into a hollow shape, and is provided at the location where the lid material 70 is fixed to the end 33 of the hollow member 30 (fixing location of the lid material 70). The fixing material 80 is disposed inside the hollow member 30, and the lid material 70 is fixed to the fixing material 80. At the fixing location of the lid material 70, the fixing material 80 is disposed inside the hollow portion 31 of the hollow member 30, and the lid material 70 is fixed to the end 33 of the hollow member 30 by the fixing material 80.

The fixing material 80 is inserted into the interior of the hollow member 30 (inside the hollow portion 31) from the opening at the end 33 of the hollow member 30, and is arranged along the inner surface of the hollow member 30. The fixing material 80 also has a number of protrusions 81 (see FIG. 11) that are distributed over the entire outer surface of the fixing material 80. The multiple protrusions 81 protrude outward from the fixing material 80 and each abut against the inner surface of the hollow member 30. The fixing material 80 is fitted into the interior of the hollow member 30 by the multiple protrusions 81, and engages with the hollow member 30.

The fixing material 80 is attached to the hollow member 30 by the screw 62 and the back plate 63, which are the mounting fixtures (see Figures 10 and 11). The fixing material 80 has a plate-shaped attachment portion 82 located on the indoor side (the curtain wall unit 2 side). The attachment portion 82 of the fixing material 80 is located inside the hollow member 30, on the indoor side of the engagement portion 32 of the hollow member 30. The back plate 63 is located inside the fixing material 80 and is provided on the indoor side of the attachment portion 82. The screw 62 is a countersunk screw, which penetrates the hollow member 30 and the attachment portion 82 of the fixing material 80 from the indoor side and is attached to the screw hole of the back plate 63. The attachment portion 82 of the fixing material 80 is sandwiched between the hollow member 30 and the back plate 63 and is attached to the hollow member 30 by the screw 62 and the back plate 63. As a result, the fixing material 80 is attached to the end portion 33 of the hollow member 30.

The connecting material 50 (see Figures 6 to 8) and the fixing material 80 (see Figures 9 to 11) are shaped members with the same cross-sectional shape and screw holes 53, 83, and are each formed from a hollow shaped member. The cross-sectional shape of a shaped member is the shape in a cross section perpendicular to the longitudinal direction of the shaped member. The shaped member of the connecting material 50 and the shaped member of the fixing material 80 are shaped members (extruded shaped members) formed by extrusion molding, and are each formed to have the same cross-sectional shape. Therefore, the connecting material 50 and the fixing material 80 are each processed, for example, by cutting the same shaped member.

The connecting material 50 and the fixing material 80 have different dimensions in the longitudinal direction of the hollow member 30, and the dimensions of the fixing material 80 are smaller than the dimensions of the connecting material 50. The dimensions of the connecting material 50 and the fixing material 80 are the dimensions from one end to the other end of each hollow member 30 in the longitudinal direction. When two hollow members 30 are connected to each other by the connecting material 50, only a portion of the end side of the connecting material 50 is disposed inside the hollow member 30 at each of the ends on both sides of the connecting material 50. In contrast, when the lid material 70 is fixed to the end 33 of the hollow member 30 by the fixing material 80, the entire fixing material 80 is disposed inside the hollow member 30. The connecting material 50 and the fixing material 80 are attached inside the hollow member 30 at the end 33 of the hollow member 30.

The connecting material 50 and the fixing material 80 each have a plurality of screw holes 53, 83. The plurality of screw holes 53, 83 are formed in the shaped material at a distance from each other and extend in the longitudinal direction of the hollow member 30. The screw holes 53 of the connecting material 50 are provided in the inner wall portion of the connecting material 50 and are located inside the connecting material 50. The screw holes 83 of the fixing material 80 are provided in the inner wall portion of the fixing material 80 and are located inside the fixing material 80.

The lid material 70 has a plurality of insertion holes 71 that are arranged to overlap the plurality of screw holes 83 of the fixing material 80 (see FIG. 9). At the fixing points of the lid material 70, a plurality of screws 64 for fixing the lid material 70 are inserted through the insertion holes 71 of the lid material 70, screwed into the screw holes 83 of the fixing material 80, and attached to the screw holes 83. The lid material 70 is fixed to the fixing material 80 by the screws 64, and is fixed to the end portion 33 of the hollow member 30 by the screws 64 and the fixing material 80. The lid material 70 covers the fixing material 80 and at least a portion of the opening (small edge) of the end portion 33 of the hollow member 30.

In the end structure 42 of the second hollow member 30 (see Figures 10 and 11), the fixing material 80 is disposed at a position closer to the inside of the hollow member 30 than the end face 34 of the hollow member 30, and is spaced from the end face 34 of the hollow member 30 toward the inside of the hollow member 30. The lid material 70 is inserted into the inside of the hollow member 30 (inside the hollow portion 31) from the opening of the end 33 of the hollow member 30, and abuts against the fixing material 80. The lid material 70 is an inner lid material disposed inside the hollow member 30, and is fixed to the fixing material 80 inside the hollow member 30. Here, the lid material 70 is not disposed outside the hollow member 30, and the entire lid material 70 is disposed inside the hollow member 30. The end face 34 of the hollow member 30 is exposed without being covered by the lid material 70.

The ends 33 of the two hollow members 30 to which the lid material 70 is fixed are adjacent to each other in the longitudinal direction of the hollow member 30 and spaced apart in the longitudinal direction of the hollow member 30 (see FIG. 10). The ends 33 of the two hollow members 30 face each other in the longitudinal direction of the hollow member 30 with a gap between them. The lid material 70 is fixed to each of the ends 33 of the two hollow members 30 that face each other in a spaced apart state in the longitudinal direction of the hollow member 30. The dimension R of the fixing material 80 in the longitudinal direction of the hollow member 30 is greater than the distance (separation distance K) between the ends 33 of the two hollow members 30 in the longitudinal direction of the hollow member 30 (R>K). This prevents the fixing material 80 and the lid material 70 from falling.

Figure 12 is a side view showing the state in which the fixing material 80 and the lid material 70 have been removed from the decorative material 3 of this embodiment, and similar to Figure 10, shows a perspective view of the inside of the hollow member 30. Figure 13 is a perspective view showing the state before and after the fixing material 80 and the lid material 70 have been removed from the decorative material 3 of this embodiment. Figure 13A shows the state before the fixing material 80 and the lid material 70 have been removed, and Figure 13B shows the state after the fixing material 80 and the lid material 70 have been removed.

As shown in the figure, for example, when the screw 62 loosens and comes off the back plate 63 and the fixing material 80, there is a concern that the fixing material 80 may come off the hollow member 30. In this way, when the fixing material 80 comes off one of the two adjacent hollow members 30 (here, the upper hollow member 30), the fixing material 80 and the lid material 70 may come off the end 33 of the hollow member 30. In this case, the fixing material 80 and the lid material 70 come out from the inside of one hollow member 30 and move toward the end 33 of the other hollow member 30 (here, the lower hollow member 30). In addition, the lid material 70 fixed to the fixing material 80 comes into contact with the lid material 70 fixed to the end 33 of the other hollow member 30.

In this case, when the dimension R of the fixing material 80 and the separation distance K satisfy the condition R>K, with a part (here, the upper part) of the fixing material 80 positioned inside the hollow member 30, the lid material 70 fixed to the fixing material 80 comes into contact with the lid material 70 fixed to the end 33 of the other hollow member 30. As a result, the fixing material 80 is held in the hollow member 30, and the fixing material 80 and the lid material 70 remain in the location (gap) between the ends 33 of the two hollow members 30. This prevents the fixing material 80 and the lid material 70 from coming off the location between the ends 33 of the two hollow members 30, and prevents the fixing material 80 and the lid material 70 from falling off.

Figure 14 is a perspective view showing the end structure 43 of the third hollow member 30 provided in the decorative material 3 of this embodiment, showing the part on the end 33 side of the hollow member 30. Figure 14A shows the end structure 43 of the third hollow member 30 in an exploded view, and Figure 14B shows the end structure 43 of the third hollow member 30 by looking through the inside of the hollow member 30. In Figure 14B, the end structure 43 of the upper hollow member 30 of the end structures 43 of the upper and lower hollow members 30 is shown by a two-dot chain line. Figure 15 is a side view showing the end structure 43 of the third hollow member 30 provided in the decorative material 3 of this embodiment, showing the inside of the hollow member 30 by looking through it. Figure 16 is a plan view showing the end structure 43 of the third hollow member 30 provided in the decorative material 3 of this embodiment, showing the end structure 43 of the third hollow member 30 as seen from the direction of the arrow X5 in Figure 15.

The end structure 43 of the third hollow member 30 is configured similarly to the end structure 42 of the second hollow member 30, except for a few details. Therefore, for the end structure 43 of the third hollow member 30, explanations of the details common to the end structure 42 of the second hollow member 30 will be omitted, and differences from the end structure 42 of the second hollow member 30 will be mainly described.

As shown in the figure, the decorative material 3 includes a lid material 75 that is fixed to a fixing material 80 by a screw 64. The lid material 75 is fixed to the end 33 of the hollow member 30 by the same fixing material 80 as the fixing material 80 of the end structure 42 of the second hollow member 30. The fixing material 80 is provided at the location where the lid material 75 is fixed to the end 33 of the hollow member 30 (the fixing location of the lid material 75). However, in the end structure 43 of the third hollow member 30, the fixing material 80 is positioned inside the hollow member 30 in accordance with the position of the end face 34 of the hollow member 30.

The lid material 75 has a plurality of through holes 76 that are arranged to overlap the plurality of screw holes 83 of the fixing material 80. At the fixing portion of the lid material 75, a plurality of screws 64 are inserted through the through holes 76 of the lid material 75, screwed into the screw holes 83 of the fixing material 80, and attached to the screw holes 83. The lid material 75 is an outer lid material arranged outside the hollow member 30, and abuts against the fixing material 80 outside the hollow member 30. The lid material 75 also abuts against the end face 34 of the hollow member 30 and is fixed to the fixing material 80. Here, the lid material 75 is not arranged inside the hollow member 30, and the entire lid material 75 is arranged outside the hollow member 30. The end face 34 of the hollow member 30 is covered and shielded by the lid material 75.

In the end structure 43 of the third hollow member 30, other features of the lid material 75 are the same as those of the lid material 70 of the end structure 42 of the second hollow member 30. The lid material 75 is fixed to each of the ends 33 of the two hollow members 30 that face each other while being spaced apart in the longitudinal direction of the hollow members 30. In the end structure 43 of the third hollow member 30, the dimension R of the fixing material 80 and the separation distance K also satisfy the condition R>K, so that the fixing material 80 and the lid material 75 are prevented from falling.

As described above, in the decorative material 3 and curtain wall 1 of this embodiment, the connecting material 50 that connects the two hollow members 30 and the fixing material 80 to which the lid materials 70, 75 are fixed are formed of shaped materials with the same cross-sectional shape having screw holes 53, 83. Therefore, by using shaped materials with the same cross-sectional shape, it is easy to connect the hollow members 30 of the decorative material 3 to each other and to fix the lid materials 70, 75 to the end 33 of the hollow member 30. In addition, each of the end structures 41 to 43 of the hollow member 30 can be easily provided on the decorative material 3. Since the lid materials 70, 75 can be fixed to the fixing material 80 using the screw holes 83 of the fixing material 80, there is no need to form screw holes in the hollow member 30, and the amount of material required to form the hollow member 30 can also be reduced.

The dimension R of the fixing material 80 in the longitudinal direction of the hollow member 30 is greater than the separation distance K between the ends 33 of the two hollow members 30 in the longitudinal direction of the hollow member 30. This prevents the fixing material 80 and the lid materials 70, 75 from coming off from the area between the two hollow members 30, and prevents the fixing material 80 and the lid materials 70, 75 from falling. In addition, in the end structure 42 of the second hollow member 30, the fixing material 80 can easily fix the lid material 70 arranged inside the hollow member 30 to the end 33 of the hollow member 30. In the end structure 43 of the third hollow member 30, the fixing material 80 can easily fix the lid material 75 abutting the end surface 34 of the hollow member 30 to the end 33 of the hollow member 30.

Depending on the thickness of the attachment portion 52 of the connecting material 50 (see Figures 7 and 8), a screw hole may be formed in the attachment portion 52 and the screw 60 may be attached to the screw hole of the attachment portion 52. In this way, the connecting material 50 may be attached to the hollow member 30 without using a back plate 61. Depending on the thickness of the attachment portion 82 of the fixing material 80 (see Figures 10 and 11), a screw hole may be formed in the attachment portion 82 and the screw 62 may be attached to the screw hole of the attachment portion 82. In this way, the fixing material 80 may be attached to the hollow member 30 without using a back plate 63.

Only one of the lid materials 70 and 75 may be provided on the decorative material 3, or both of the lid materials 70 and 75 may be provided on the decorative material 3. The type of curtain wall 1 on which the decorative material 3 is provided is not particularly limited. Therefore, the curtain wall 1 may be, for example, a curtain wall having an uneven shape (for example, a sawtooth shape or a zigzag shape) in the cross section in the left-right direction, or a flat shape. The curtain wall 1 may also be a curtain wall that does not have a curtain wall unit 2. The decorative material 3 is not limited to the decorative material of the curtain wall, and may be installed on the wall of a building other than the curtain wall, for example.

As mentioned above, cosmetic materials are:
A decorative material having hollow members arranged in a longitudinal direction,
a connecting member provided at a location where two adjacent hollow members are connected to each other and disposed inside the two hollow members to connect the two hollow members;
a fixing member provided at a location where a lid material is fixed to an end portion of the hollow member and disposed inside the hollow member to fix the lid material;
The connecting material and the fixing material are shaped members having the same cross-sectional shape and having screw holes,
The lid material is a decorative material that is fixed to the fixing material by screws attached to the screw holes of the fixing material.
Therefore, by using a shape having the same cross-sectional shape, it is possible to easily connect the hollow members of the decorative material to each other and to fix the lid material to the ends of the hollow members.

The lid member is fixed to two ends of the hollow member that face each other while being spaced apart in the longitudinal direction of the hollow member,
The dimension of the fixing material in the longitudinal direction of the hollow members is greater than the distance between the ends of the two hollow members in the longitudinal direction of the hollow members.
Therefore, the fixing material and the lid material can be prevented from coming off from the portion between the two hollow members, and the fixing material and the lid material can be prevented from falling off.

The lid material is disposed inside the hollow member and fixed to the fixing material.
Therefore, the lid material disposed inside the hollow member can be easily fixed to the end portion of the hollow member by the fixing material.

The lid material is fixed to the fixing material by abutting against an end face of the hollow member.
Therefore, the lid material that abuts against the end face of the hollow member can be easily fixed to the end of the hollow member by the fixing material.

A curtain wall is a curtain wall with decorative materials.
Therefore, in the decorative material of a curtain wall, it is possible to easily connect the hollow members of the decorative material to each other and to fix the lid material to the ends of the hollow members by using shaped members having the same cross-sectional shape.
