The following describes an embodiment of the interior structure, building, and construction method according to the present invention with reference to the drawings. The same components in each drawing are given the same reference numerals.

Figure 1 is a diagram showing a building 100 as one embodiment of a building according to the present invention. In Figure 1, only a room 101 is shown as an example of an indoor space in the building 100. The room 101 shown in Figure 1 is partitioned by an interior wall 102, an interior floor 103, and an interior ceiling 104. The room 101 is provided with an interior structure as an example of an interior structure according to the present invention. As shown in Figure 1, the room 101 has an open ceiling section 105. In other words, the room 101 is formed across two adjacent floors in the vertical direction. The use of such a room 101 is not particularly limited, but it may be, for example, a living/dining/kitchen room in a two-story detached house.

2 is a diagram showing an interior wall portion 10 constituting at least a part of an interior wall 102, and an interior floor portion 20 constituting at least a part of an interior floor 103. The interior wall portion 10 is formed by connecting strip-shaped interior wall materials 30 in the material width direction B with the material length direction A being vertical. The position where the interior wall portion 10 is formed in the interior wall 102 is not particularly limited. As shown in FIG. 1, the interior wall portion 10 may be formed, for example, in a portion of the interior wall 102 facing the atrium portion 105. The interior floor portion 20 is formed by connecting strip-shaped interior floor materials 40 in the material width direction E. The interior ceiling 104 may include an interior ceiling portion formed by connecting strip-shaped interior ceiling materials in the material width direction.

3 is a front view of the interior wall portion 10. As shown in FIG. 3, the interior wall portion 10 is formed by connecting three types of strip-shaped interior wall materials 30 with different material widths Wm in the material width direction B, except for the strip-shaped interior wall materials 30 located at both ends. The interior wall materials 30 can be formed from, for example, wood, tile material, etc., but the material for forming them is not particularly limited. Hereinafter, for the convenience of explanation, each of the above-mentioned "strip-shaped interior wall materials 30 located at both ends" will be described as "end wall material 31". In addition, when the above-mentioned "three types of strip-shaped interior wall materials 30 with different material widths Wm" are to be distinguished from each other, they will be described as "narrow-width wall material 32", "medium-width wall material 33", and "wide-width wall material 34", and when no particular distinction is made, they will be simply described as "three types of interior wall materials 32 to 34". The narrow-width wall material 32 has the narrowest material width Wm1 among the three types of interior wall materials 32 to 34. The wide wall material 34 has the widest material width Wm3 among the three types of interior wall materials 32 to 34. The medium-width wall material 33 has a material width W2 that is wider than the material width Wm1 of the narrow wall material 32 and narrower than the material width Wm3 of the wide wall material 34.

As shown in FIG. 3, in the interior wall section 10, at least two narrow wall materials 32, medium wall materials 33, and wide wall materials 34 are connected vertically, which is the material length direction A, via joints 50. In the interior wall section 10, the three types of interior wall materials 32 to 34 are connected in the material width direction B with the vertical positions of the joints 50 of adjacent ones in the material width direction B being different. In other words, in the interior wall section 10, there are a narrow wall material row formed by connecting two or more narrow wall materials 32 via joints 50 in the vertical direction, a medium wall material row formed by connecting two or more medium wall materials 33 via joints 50 in the vertical direction, and a wide wall material row formed by connecting two or more wide wall materials 34 via joints 50 in the vertical direction. In the interior wall section 10, when any two adjacent rows in the material width direction B are focused on, the positions of the joints 50 in these two rows are different in the vertical direction.

In this way, in the interior wall section 10, three types of interior wall materials 32 to 34 with different material widths Wm are connected in the material width direction B with adjacent joints 50 in the material width direction B at different vertical positions, which makes it difficult to give a monotonous impression and improves the design.

As shown in FIG. 3, the vertical separation distance T between any two adjacent seams 50 in the material width direction B is preferably 100 mm or more, and more preferably longer than any of the material widths Wm1 to Wm3 of at least the three types of interior wall materials 32 to 34. This makes it less likely that the interior wall material will look monotonous, and improves the design. In this embodiment, the seams 50 extend horizontally in a straight line when viewed from the front of the interior wall portion 10 (see FIG. 3), but this shape is not limited to this. In the case where the seams 50 do not extend horizontally in a straight line when viewed from the front of the interior wall portion 10 (see FIG. 3), the separation distance T refers to the shortest vertical separation distance.

In the interior wall section 10 of this embodiment, three types of interior wall materials 32-34 with different material widths Wm are used, but this configuration is not limited to this. As will be described in detail later, the interior wall section 10 may use four types of interior wall materials with different material widths Wm (see FIG. 9). In this way, by narrowing down the interior wall materials 30 with different material widths Wm that are arranged between the end wall materials 31 to three or four types, in addition to improving the design as described above, the manufacturing efficiency of the interior wall materials 30 can be improved.

As shown in FIG. 3, the formation area FA of the interior wall portion 10 in the interior wall 102 is partitioned by various partitioning parts 110. FIG. 4 is a diagram showing details of the vertical lower end of the interior wall portion 10 of this embodiment. Also, FIG. 5 is a diagram showing details of the horizontal end of the interior wall portion 10 of this embodiment. As shown in FIGS. 4 and 5, the partitioning part 110 of this embodiment is composed of a partition material 110a attached to the interior wall 102. The partition material 110a is a frame material that surrounds the formation area FA. However, the partitioning part 110 is not limited to the partition material 110a of this embodiment. The partitioning part 110 that partitions the vertical lower side of the formation area FA may be, for example, the interior floor 103. Also, the partitioning part 110 that partitions the vertical upper side of the formation area FA may be, for example, the interior ceiling 104. Furthermore, the partitioning portion 110 that partitions both sides of the formation area FA in the horizontal direction may be, for example, a portion of the interior wall 102 that extends perpendicular to the interior wall portion 10.

In this way, the interior wall portion 10 is provided in a predetermined formation area FA in the interior wall 102. The vertical height Hp and horizontal width Wp of the formation area FA are not particularly limited. The interior wall portion 10 of this embodiment is formed by connecting three types of interior wall materials 32-34 in the material width direction B in this formation area FA. However, the horizontal width Wp of the formation area FA does not necessarily match the width that can be achieved by connecting the three types of interior wall materials 32-34 in the material width direction B. In other words, there are cases where it is not possible to fill up the entire horizontal width Wp of the formation area FA only by connecting the three types of interior wall materials 32-34 in the material width direction B. In such a case, the end wall material 31 arranged at the horizontal end of the formation area FA is an adjustment wall material having a material width Wm4 different from the material widths Wm1-Wm3 of the three types of interior wall materials 32-34. This allows the horizontal width Wp of the formation area FA to be filled with the three types of interior wall materials 32-34 and the end wall material 31 as an adjustment member. In this way, the end wall material 31 arranged at the horizontal end of the formation area FA may be composed of any of the three types of interior wall materials 32-34, or may be composed of an adjustment member that does not correspond to any of the three types of interior wall materials 32-34. Therefore, as described above, the positions at which the three types of interior wall materials 32-34 are connected in the material width direction B are specified as positions excluding the end wall material 31, "excluding the strip-shaped interior wall materials 30 located at both ends." Note that FIG. 3 shows an example in which all of the end wall materials 31 arranged at both horizontal ends of the formation area FA are composed of adjustment members.

An example of a construction method for the interior wall portion 10 in a case where at least one of the two end wall materials 31 arranged at both horizontal ends of the formation area FA is made of one of the three types of interior wall materials 32 to 34 will be described later (see Figure 9).

As shown in Figs. 4 and 5, in the interior wall section 10, three types of interior wall materials 32 to 34 may be fixed to the surface of the gypsum board 120, for example, by adhesive. The three types of interior wall materials 32 to 34 may also be fixed to a plywood serving as a wall base material 121 located on the back side of the gypsum board 120, for example, by a fastening member such as a screw. Furthermore, the end wall material 31 described above may also be fixed to the gypsum board 120 and the wall base material 121 in the same manner as the three types of interior wall materials 32 to 34. In other words, all of the strip-shaped interior wall materials 30 forming the interior wall section 10 may be fixed to the gypsum board 120 and the wall base material 121 by the above-mentioned method. However, the method of fixing the strip-shaped interior wall material 30 forming the interior wall section 10 is not limited to the above-mentioned method.

Figure 6 is a plan view showing the narrow wall material 32 alone, one of the three types of interior wall materials 32 to 34. Figure 7 is a cross-sectional view of the narrow wall material 32 at the position of line I-I in Figure 6. Although Figures 6 and 7 show the narrow wall material 32, the cross-sectional shapes shown in Figure 7 are similar for the medium wall material 33 and wide wall material 34, with only the material width Wm being different.

As shown in FIG. 7, the narrow wall material 32 has a front mounting portion 32a and a back mounting portion 32b on both end faces in the material width direction B, which are attached to another adjacent interior wall material 30 in the material thickness direction C. More specifically, the narrow wall material 32 of this embodiment has a main body portion 32c, a front mounting portion 32a protruding from the main body portion 32c to one side in the material width direction B, and a back mounting portion 32b protruding from the main body portion 32c to the other side in the material width direction B. The front mounting portion 32a protrudes from a part of the front side (upper side in FIG. 7) in the material thickness direction C of the end face on one side of the main body portion 32c in the material width direction B. The back mounting portion 32b protrudes from a part of the back side (lower side in FIG. 7) in the material thickness direction C of the end face on the other side of the material width direction B of the main body portion 32c.

Although details will be described later, in this embodiment, the narrow wall material 32 is adjacent to the medium-width wall material 33 on one side in the material width direction B (see FIG. 3). Therefore, the front side mounting portion 32a provided on the end face on one side of the narrow wall material 32 in the material width direction B is stacked so as to cover the back side mounting portion of the adjacent medium-width wall material 33, which has a shape similar to the above-mentioned back side mounting portion 32b. In this way, the narrow wall material 32 and the medium-width wall material 33 are adjacent to each other with the front side mounting portion 32a of the narrow wall material 32 and the back side mounting portion of the medium-width wall material 33 stacked in the material thickness direction C.

As will be described in detail later, the narrow wall material 32 of this embodiment is adjacent to the wide wall material 34 on the other side in the material width direction B (see FIG. 3). Therefore, the back side mounting portion 32b provided on the end surface on the other side in the material width direction B of the narrow wall material 32 is stacked so as to be covered by the front side mounting portion of the adjacent wide wall material 34, which has a shape similar to that of the above-mentioned front side mounting portion 32a. In this way, the narrow wall material 32 and the wide wall material 34 are adjacent to each other with the back side mounting portion 32b of the narrow wall material 32 and the front side mounting portion of the wide wall material 34 stacked in the material thickness direction C.

As described above, the three types of interior wall materials 32-34 may be fixed to the plywood as the wall base material 121 by fastening members such as screws. When the three types of interior wall materials 32-34 are fixed to the plywood as the wall base material 121, they may be fixed by fastening members such as screws using the back side mounting portion 32b described above. In this way, the back side mounting portion 32b is covered by the front side mounting portion of the adjacent wide wall material 34, so that the fastening members are prevented from being visible from the room 101 side as the indoor space, and the design of the interior wall section 10 can be further improved. Similarly, the medium-width wall material 33 and the wide wall material 34 may also be fixed to the plywood as the wall base material 121 by fastening members such as screws using the back side mounting portion.

As shown in Figure 3, in the interior wall section 10, it is preferable that the three types of interior wall materials 32-34 are connected in the material width direction B in a predetermined repeating pattern in which adjacent interior wall materials 32-34 in the material width direction B are different types. That is, in this embodiment, the narrow wall material 32 is not adjacent to the narrow wall material 32 in the material width direction B, but is adjacent to the medium wall material 33 or the wide wall material 34. Similarly, the medium wall material 33 is not adjacent to the medium wall material 33 in the material width direction B, but is adjacent to the narrow wall material 32 or the wide wall material 34. Furthermore, the wide wall material 34 is not adjacent to the wide wall material 34 in the material width direction B, but is adjacent to the narrow wall material 32 or the medium wall material 33. In this way, in the interior wall section 10, the three types of interior wall materials 32-34 are connected in the material width direction B so that the same types of interior wall materials 32-34 are not adjacent to each other, making it less likely to give a monotonous impression and further improving the design.

The three types of interior wall materials 32 to 34 in this embodiment are a first type interior wall material with a material width of 150 mm, a second type interior wall material with a material width of 120 mm, and a third type interior wall material with a material width of 90 mm. That is, the narrow-width wall material 32 in this embodiment is made of a third type interior wall material, and the material width Wm1 is 90 mm. The medium-width wall material 33 in this embodiment is made of a second type interior wall material, and the material width Wm2 is 120 mm. Furthermore, the wide-width wall material 34 in this embodiment is made of a first type interior wall material, and the material width Wm3 is 150 mm. The first type interior wall material, the second type interior wall material, and the third type interior wall material can be easily cut by using strips with material widths of 150 mm, 120 mm, and 90 mm, which are widely distributed as interior floor materials.

From the viewpoint of ease of cutting, the fourth type interior wall material with a material width of 60 mm may be used in place of any of the first, second and third type interior wall materials described above. However, when the fourth type interior wall material is used, in order to suppress extreme variations in the material width Wm, it is preferable that the three types of interior wall materials 32 to 34 are composed of the second, third and fourth type interior wall materials. However, when the fourth type interior wall material is used, the number of interior wall materials required increases. Therefore, from the viewpoint of workability, etc., it is preferable that the three types of interior wall materials 32 to 34 are composed of the first, second and third type interior wall materials described above.

As described above, in this embodiment, three types of interior wall materials 32 to 34 are used, but four types of interior wall materials may be used. FIG. 8 shows an example in which four types of interior wall materials 35 to 38 are used. As shown in FIG. 8, the interior wall portion 10 may be formed by connecting four types of strip-shaped interior wall materials 30 with different material widths Wm in the material width direction B, except for the end wall materials 31 as strip-shaped interior wall materials 30 located at both ends. Hereinafter, when the above-mentioned "four types of strip-shaped interior wall materials 30 with different material widths Wm" are to be distinguished from one another, they will be described as "narrow-width wall material 35," "medium-narrow-width wall material 36," "medium-wide-width wall material 37," and "wide-width wall material 38," and when no particular distinction is made, they will be simply described as "four types of interior wall materials 35 to 38." The narrow-width wall material 35 has the narrowest material width Wm5 among the four types of interior wall materials 35 to 38. The wide-width wall material 38 has the widest material width Wm8 among the four types of interior wall materials 35 to 38. The material width Wm6 of the intermediate narrow wall material 36 and the material width Wm7 of the intermediate wide wall material 37 are wider than the material width Wm5 of the narrow wall material 35 and narrower than the material width Wm8 of the wide wall material 38. In addition, the material width Wm6 of the intermediate narrow wall material 36 is narrower than the material width Wm7 of the intermediate wide wall material 37.

As shown in Figure 8, in the interior wall section 10, at least two of the narrow wall material 35, medium narrow wall material 36, medium wide wall material 37 and wide wall material 38 are connected in the vertical direction, which is the material length direction A, via joints 50. In the interior wall section 10, the four types of interior wall materials 35 to 38 are connected in the material width direction B with the vertical positions of adjacent joints 50 in the material width direction B being different. That is, in the interior wall section 10 shown in FIG. 8, there are a narrow wall material row formed by connecting two or more narrow wall materials 35 with joints 50 in the vertical direction, a medium narrow wall material row formed by connecting two or more medium narrow wall materials 36 with joints 50 in the vertical direction, a medium wide wall material row formed by connecting two or more medium wide wall materials 37 with joints 50 in the vertical direction, and a wide wall material row formed by connecting two or more wide wall materials 38 with joints 50 in the vertical direction. In the interior wall section 10 shown in FIG. 8, when any two adjacent rows in the material width direction B are focused on, the positions of the joints 50 in these two rows are different in the vertical direction.

The narrow wall material 35 shown in FIG. 8 is made of the above-mentioned fourth-class interior wall material with a material width of 60 mm, and its material width Wm5 is 60 mm. The medium-narrow wall material 36 shown in FIG. 8 is made of the above-mentioned third-class interior wall material with a material width of 90 mm, and its material width Wm6 is 90 mm. The medium-wide wall material 37 shown in FIG. 8 is made of the above-mentioned second-class interior wall material with a material width of 120 mm, and its material width Wm7 is 120 mm. Furthermore, the wide wall material 38 shown in FIG. 8 is made of the above-mentioned first-class interior wall material with a material width of 150 mm, and its material width Wm8 is 150 mm. The dimensions of the material widths Wm of the narrow wall material 35, the medium-narrow wall material 36, the medium-wide wall material 37, and the wide wall material 38 are not limited to the above dimensions as long as the relationship Wm5<Wm6<Wm7<Wm8 is satisfied. However, from the viewpoint of ease of cutting, it is preferable that the four types of interior wall materials 35 to 38 are composed of the above-mentioned first, second, third, and fourth interior wall materials.

Furthermore, the four types of interior wall materials 35-38 shown in FIG. 8 are connected in the material width direction B in a predetermined repeating pattern in which the types of adjacent interior wall materials 35-38 in the material width direction B are different, similar to the three types of interior wall materials 32-34 shown in FIG. 3. That is, in the example shown in FIG. 8, the narrow wall material 35 is not adjacent to the narrow wall material 35 in the material width direction B. Moreover, the medium narrow wall material 36 is not adjacent to the medium narrow wall material 36 in the material width direction B. Furthermore, the medium wide wall material 37 is not adjacent to the medium wide wall material 37 in the material width direction B. Furthermore, the wide wall material 38 is not adjacent to the wide wall material 38 in the material width direction B.

More specifically, in the example shown in FIG. 8, except for the end wall materials 31 located at both ends, the wide wall material 38, the medium narrow wall material 36, the medium wide wall material 37, and the narrow wall material 35 are connected in a repeated manner from left to right. That is, in the example shown in FIG. 8, the narrow wall material 35 and the medium narrow wall material 36 are adjacent to the medium wide wall material 37 and the wide wall material 38 in the material width direction B. In other words, the medium wide wall material 37 and the wide wall material 38 are adjacent to the narrow wall material 35 and the medium narrow wall material 36 in the material width direction B.

However, the four types of interior wall materials 35-38 may be connected in the material width direction B in a repeating pattern different from the repeating pattern shown in FIG. 8. The four types of interior wall materials 35-38 may be connected in the material width direction B, for example, so that any one type of interior wall material 35-38 is sandwiched between the other three types of interior wall materials 35-38. One example of such a repeating pattern is a repeating pattern in which, from one side to the other side of the material width direction B, a wide wall material 38, a narrow wall material 35, a medium wide wall material 37, a narrow wall material 35, a medium narrow wall material 36, and a narrow wall material 35 form one cycle. However, the one type of interior wall material 35-38 interposed every other one is not limited to the narrow wall material 35 in the above example.

Next, referring again to Figures 1 to 3, further details of the interior wall portion 10 in which three types of interior wall materials 32 to 34 are connected will be described. As shown in Figures 1 and 2, the interior floor 103 of the room 101 as an indoor space has an interior floor portion 20 formed by connecting plate-shaped interior floor materials 40 in the material width direction E. As shown in Figure 2, the interior wall portion 10 of this embodiment rises from the interior floor portion 20 at least on one end side of the material length direction D of the interior floor material 40. With this configuration, the continuity of the interior wall portion 10 and the interior floor portion 20 can be emphasized, and the unity of the interior wall portion 10 and the interior floor portion 20 can be emphasized. As a result, the design of the interior wall portion 10 and the interior floor portion 20 as a whole can be improved compared to a configuration in which the interior wall portion 10 rises from the interior floor portion 20 at least on one end side of the material width direction E of the interior floor material 40.

In addition, the interior floor section 20 is preferably formed by connecting strip-shaped interior floor materials 40 of equal material width in the material width direction E, except for the strip-shaped interior floor materials 40 located at both ends. In this way, there is no need to prepare interior floor materials 40 of different material widths, and the productivity of the interior floor materials 40 and the workability of the interior floor section 20 can be improved. As the interior floor material 40, for example, a strip material for interior floor materials with a material width of 180 mm or 120 mm that is widely available can be used. The reason for specifying "excluding the strip-shaped interior floor materials 40 located at both ends" is the same as the reason for the end wall material 31 of the interior wall section 10 described above, so an explanation will be omitted here.

As shown in FIG. 2, it is preferable that at least one of the vertical lines 70 extending vertically between two adjacent interior wall materials 30 in the material width direction B in the interior wall section 10 is arranged so that the position in the material width directions B and E coincides with at least one of the horizontal lines 80 extending horizontally between two adjacent interior floor materials 40 in the material width direction E in the interior floor section 20. In this way, the continuity of the interior wall section 10 and the interior floor section 20 described above can be further emphasized. In the example shown in FIG. 2, the vertical line 70 formed between the narrow-width wall material 32 having a material width Wm1 of 90 mm and the medium-width wall material 33 having a material width Wm2 of 120 mm is aligned with the horizontal line 80 formed by the interior floor materials 40 having a material width Wm9 of 180 mm in the material width directions B and E. More specifically, in this embodiment, the total material width of the three connected interior wall materials 32-34 is 360 mm (90 mm + 120 mm + 150 mm). In other words, in this embodiment, the total material width of the three connected interior wall materials 32-34 (360 mm in this embodiment) is an integer multiple of the material width Wm9 of the interior floor material 40 (180 mm in this embodiment). In this way, the positions of the vertical line 70 and horizontal line 80 described above can be aligned for each cycle of the repeating pattern in which the three types of interior wall materials 32-34 are arranged adjacent to each other in a row in the material width direction B.

Note that, here, the relationship between the interior floor section 20 and the interior wall section 10 (see Figures 2 and 3) in which three types of interior wall materials 32-34 are connected has been described, but even in the case of an interior wall section 10 (see Figure 8) in which four types of interior wall materials 35-38 are connected, the relationship with the interior floor section 20 may be similar to that described above.

Next, an example of a construction method for the interior wall portion 10 will be described with reference to FIG. 9. FIG. 9 is a diagram for explaining an example of a construction method for the interior wall portion 10 shown in FIG. 3, in which three types of interior wall materials 32-34 are connected in the material width direction B. However, a similar construction method can also be applied to the interior wall portion 10 shown in FIG. 8, in which four types of interior wall materials 35-38 are connected in the material width direction B. Therefore, only the construction method for the interior wall portion 10 shown in FIG. 3 will be described here.

The construction method of the interior wall section 10 includes a connecting process in which the interior wall section 10 is formed by connecting the strip-shaped interior wall material 30 in the material width direction B with the material length direction A in the vertical direction. In the connecting process, the strip-shaped interior wall material 30 is connected from the position of the partitioning portion 110 that partitions one horizontal end side (left side in FIG. 9) of the formation area FA in which the interior wall section 10 is formed, toward the position of the partitioning portion 110 that partitions the other horizontal end side (left side in FIG. 9) of the formation area FA.

Figure 9 shows a construction method for constructing the end wall material 31 that constitutes one horizontal end of the interior wall section 10 from three types of narrow-width wall materials 32 of interior wall materials 32 to 34, without using an adjustment wall material. Specifically, in the example shown in Figure 9, in the connecting process, the narrow-width wall material 32 as one type of interior wall material 30 with the smallest material width Wm among the three types of band-shaped interior wall materials 32 to 34 with different material widths Wm is placed at a position that will be one horizontal end of the interior wall section 10 (the left end in Figure 9). Then, the three types of interior wall materials 32 to 34 are connected sequentially in the material width direction B from the position that will be one horizontal end of the interior wall section 10 to the position that will be the other end (the right end in Figure 9).

In this way, at least one of the two end wall materials 31 constituting both horizontal ends of the interior wall section 10 can be made of the narrow-width wall material 32. Therefore, it is possible to prevent both end wall materials 31 from becoming adjustment members, and to reduce the effort required to prepare adjustment members having a material width Wm4 different from the three types of interior wall materials 32 to 34. This improves the workability of the interior wall section 10. In addition, the material width Wm4 of the adjustment member is often narrower than the material width Wm1 of the narrow-width wall material 32, which has the smallest material width Wm among the three types of interior wall materials 32 to 34, or is approximately the same as the material width Wm1 of the narrow-width wall material 32. Therefore, by arranging the narrow-width wall material 32 at a position that is one horizontal end of the interior wall section 10 (the left end in FIG. 9), it is possible to reduce the possibility that the interior wall section 10 will have a different impression at both horizontal end positions, even if an adjustment member is arranged at a position that is the other horizontal end of the interior wall section 10 (the right end in FIG. 9). In other words, deterioration of the design of the interior wall portion 10 can be suppressed.

In addition, FIG. 9 shows an example in which a narrow-width wall material 32 with a material width Wm1 of 90 mm, a medium-width wall material 33 with a material width Wm2 of 120 mm, and a wide-width wall material 34 with a material width Wm3 of 150 mm are used. Also, FIG. 9 shows an adjustment member with a material width Wm4 of 70 mm as the end wall material 31 arranged at the other horizontal end (the right end in FIG. 9) of the interior wall portion 10. However, the dimensions of the material widths Wm1 to Wm4 of the narrow-width wall material 32, medium-width wall material 33, wide-width wall material 34, and adjustment member are not limited to the above dimensions. Also, FIG. 9 shows an example in which the end wall material 31 arranged at the other horizontal end (the right end in FIG. 9) of the interior wall portion 10 is composed of an adjustment member, but depending on the horizontal width Wp of the formation area FA, it may be composed of one of the three types of interior wall materials 32 to 34.

In the example shown in Figure 9, the three types of interior wall materials 32 to 34 are formed as is or by cutting a strip of plate material with a length in the material length direction A of 1800 mm. Strip of plate material with a length in the material length direction A of 1600 mm to 2000 mm, and particularly strip of plate material with a length in the material length direction A of 1800 mm, are widely distributed and therefore are advantageous in that they are easy to obtain at low cost.
