Description

Technical Field

[0001] The present invention relates to a wall joint structure.

Background Art

[0002] In buildings such as houses, a skirting board is attached along the lower end of the wall, and a cornice is attached along the upper end of the wall. The skirting board is a joint material that covers the boundary between the wall and the floor, and the cornice is a joint material that covers the boundary between the wall and the ceiling.

[0003] In a building, when a wall is arranged in an L shape in plan view, a corner portion may be formed on the wall. When a skirting board is attached to such a wall, the skirting board is attached along each of the wall surfaces forming a right angle. Further, Patent Document 1 discloses a configuration in which a corner cover is provided to cover the gap between these skirting boards. This corner cover is formed in an L shape and is attached so as to straddle the surfaces of the respective skirting boards.

Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, on the wall of a building, a step may occur on the wall surface for reasons such as a part of the thickness in the wall width direction being large. In this case, the wall surface has two wall surfaces (hereinafter referred to as the first wall surface and the second wall surface) that are continuous via the step (step surface). When attaching a skirting board to such a stepped wall surface, the skirting board is individually attached to the first wall surface and the second wall surface.

[0006] However, simply attaching the skirting boards to the first wall surface and the second wall surface may result in gaps between the skirting boards, which may damage the appearance. Therefore, it is conceivable to cover the above gaps using the corner cover of Patent Document 1. However, since this corner cover has an L shape adapted to the corner portion of the wall, it is not suitable for covering the above gaps.

[0007] Also, it is conceivable to form a flat plate-shaped cover for covering the above gaps and attach the cover to the stepped surface. However, since the width of the stepped surface is extremely small, it is considered difficult to attach the cover to the stepped surface in a stable state.

[0008] Note that the above-described problem is not a problem that occurs only with skirting boards, but is a problem that can also occur at the edge trim in the same manner.

[0009] The present invention has been made in view of the above circumstances, and when attaching a partition material to each wall surface continuous through a stepped surface, while suppressing damage to the appearance, it is possible to stably attach the partition material. The main object is to provide a partition structure for a wall.

Means for Solving the Problems

[0010] To solve the above problems, a partition structure for a wall according to a first invention is a partition structure for a wall including a partition material provided along the lower end or upper end of a wall surface facing an indoor space, wherein the wall surface includes a first wall surface and a second wall surface continuous through a stepped surface, and as the partition material, a first partition material provided along the first wall surface, a second partition material provided along the second wall surface, and a third partition material provided across the first wall surface and the second wall surface and adjacent to the first partition material and the second partition material, respectively, and the third partition material has a stepped shape along the first wall surface, the stepped surface, and the second wall surface, respectively, in a plan view.

[0011] According to the first invention, among the first wall surface and the second wall surface that are continuous via the stepped surface, a first parting material is provided along the first wall surface, and a second parting material is provided along the second wall surface. Further, a third parting material is provided straddling the first wall surface and the second wall surface, and the third parting material is adjacent to the first parting material and the second parting material respectively. In this case, a continuous parting structure by the first to third parting materials can be constructed without a gap occurring between the first parting material and the second parting material. Further, the third parting material has a stepped shape along the first wall surface, the stepped surface, and the second wall surface respectively in plan view. In this case, a parting structure adapted to the steps of each wall surface can be constructed. Therefore, it is possible to suppress the appearance from being impaired.

[0012] Further, the third parting material can be attached by fixing the portion along the first wall surface to the first wall surface and the portion along the second wall surface to the second wall surface in the third parting material. Since the first wall surface and the second wall surface are wide surfaces unlike the stepped surface, in this case, the third parting material can be attached in a stable state.

[0013] The wall parting structure of the second invention includes, in the first invention, a first wall portion that forms the wall surface, the first wall portion has a first wall portion and a second wall portion adjacent in the wall width direction, the second wall portion is formed to project more toward the indoor space side than the first wall portion, the first wall surface is formed by the first wall portion, the second wall surface is formed by the second wall portion, and at the boundary between the first wall portion and the second wall portion, the stepped surface that causes a step between the first wall surface and the second wall surface is formed.

[0014] According to the second invention, the first wall portion forming the wall surface has a first wall portion and a second wall portion adjacent to each other in the wall width direction. The second wall portion is formed to project toward the indoor space side more than the first wall portion. In this case, the first wall surface formed on the first wall portion and the second wall surface formed on the second wall portion are continuous via a stepped surface formed at the boundary between the first wall portion and the second wall portion. And in the present invention, the cut-off structure of the first invention is applied to the wall surface of the first wall portion having such a step. Thereby, when attaching the cut-off material to the wall surface of the first wall portion, the effects of the first invention described above can be obtained.

[0015] The cut-off structure of the wall of the third invention, in the second invention, includes the first wall portion forming the wall surface, and the first wall portion has an inner wall plate portion and an outer wall plate portion provided so as to overlap the surface of the inner wall plate portion and arranged in a part of the wall width direction of the inner wall plate portion. A region of the surface of the inner wall plate portion where the outer wall plate portion is not overlapped is the first wall surface, the surface of the outer wall plate portion is the second wall surface, and an end surface on the first wall surface side in the outer wall plate portion is the stepped surface.

[0016] According to the third invention, a step corresponding to the plate thickness of the outer wall plate portion is generated between the first wall surface and the second wall surface. And in the present invention, the cut-off structure of the first invention is applied to such a configuration. Thereby, when attaching the cut-off material to the wall surface where a small step such as a step corresponding to the plate thickness is generated, it is possible to attach the cut-off material in a stable state while suppressing the appearance from being impaired.

[0017] The partition structure of the fourth invention, in the first invention, includes a decorative column in which a plurality of or one pillar is surrounded by a square cylindrical decorative board portion. Each side surface of the decorative board portion includes a first side surface and a second side surface that are perpendicular to each other. The second wall portion that forms the first wall surface is arranged in a state where an end portion in the wall width direction is in contact with the first side surface of the decorative board portion of the decorative column, and the third wall portion that forms the second wall surface is arranged in a state where an end portion in the wall width direction is in contact with the second side surface of the decorative board portion. The corner portion between the first side surface and the second side surface in the decorative board portion protrudes toward the indoor space side from between the first wall surface and the second wall surface. Each side surface of the protruding portion at the corner portion becomes a first stepped surface and a second stepped surface as the stepped surfaces, respectively. The first wall surface and the second wall surface are continuous via the first stepped surface and the second stepped surface. The third partition material has a stepped shape along the first wall surface, the first stepped surface, the second stepped surface, and the second wall surface, respectively, in a plan view.

[0018] According to the fourth invention, a decorative column is provided in which a plurality of or one pillar is surrounded by a square cylindrical decorative board portion. The second wall portion that forms the first wall surface is arranged in a state where an end portion in the wall width direction is in contact with the first side surface of the decorative board portion of the decorative column, and the third wall portion that forms the second wall surface is arranged in a state where an end portion in the wall width direction is in contact with the second side surface of the decorative board portion. Here, in such a configuration, for reasons such as complying with the module design, the corner portion between the first side surface and the second side surface in the decorative board portion may protrude toward the indoor space side from between the first wall surface and the second wall surface. In this case, the first wall surface and the second wall surface are continuous via each side surface (the first stepped surface and the second stepped surface) of the protruding portion.

[0019] And in the present invention, the partition structure of the first invention is applied to such a configuration. Specifically, the third partition material has a stepped shape along the first wall surface, the first stepped surface, the second stepped surface, and the second wall surface, respectively, in a plan view. According to such a configuration, it is possible to suppress the appearance from being impaired when attaching the third partition material to the first wall surface and the second wall surface that are continuous via the two stepped surfaces.

[0020] The parting structure of the fifth invention is as follows. In the fourth invention, the decorative panel portion has a rectangular tubular inner decorative panel portion and a rectangular tubular outer decorative panel portion provided so as to overlap the outside of the inner decorative panel portion. The first side surface and the second side surface are formed on the outer decorative panel portion. Each outer surface of the inner decorative panel portion includes a first outer surface facing the same side as the first side surface and a second outer surface facing the same side as the second side surface. The second wall portion is arranged with the first wall surface positioned on the same plane as the second outer surface, and the third wall portion is arranged with the second wall surface positioned on the same plane as the first outer surface. The protruding portion is formed at the corner portion of the outer decorative panel portion.

[0021] In the decorative column, the decorative panel portion may have a two-layer structure of an inner decorative panel portion and an outer decorative panel portion for reasons such as suppressing the spread of fire to the column. Also, in such a configuration, for reasons such as complying with the module design, the second wall portion may be arranged with the first wall surface positioned on the same plane as the second outer surface of the inner decorative panel portion, and the third wall portion may be arranged with the second wall surface positioned on the same plane as the first outer surface of the inner decorative panel portion. Here, in such a configuration, the corner portion of the outer decorative panel portion protrudes toward the indoor space side, and the first stepped surface and the second stepped surface are formed by the protruding portion. In this case, the width of each of these stepped surfaces is the same as the thickness of the outer decorative panel portion.

[0022] In the fifth invention, the parting structure of the first invention is applied to the above configuration. Thereby, when a small step such as a step corresponding to the thickness of the plate occurs, the third parting material can be stably attached to the first wall surface and the second wall surface via each stepped surface while suppressing the deterioration of the appearance.

Mode for Carrying Out the Invention

[0024] [First Embodiment] Hereinafter, an embodiment embodying the present invention will be described with reference to the drawings. Note that FIG. 1 is a cross-sectional view showing a wall portion provided in a building. In the present embodiment, the building is an apartment building having a plurality of dwelling units.

[0025] As shown in FIG. 1, in the building 10, a plurality of adjacent dwelling units X1, X2 are provided. In FIG. 1, the boundary K between these dwelling units X1, X2 is shown by a two-dot chain line. Rooms 11 and 12 are provided in the dwelling unit X1, and a room 13 is provided in the dwelling unit X2. These rooms 11 to 13 are, for example, living rooms. However, the rooms 11 to 13 may be non-living rooms such as corridors.

[0026] In the building 10, a plurality of wall portions 15 and 16 are provided. The wall portion 15 partitions the room 11 from each of the rooms 12 and 13. The rooms 12 and 13 are arranged in the wall width direction of the wall portion 15. The wall portion 16 partitions the rooms 12 and 13. In this case, the wall portion 16 is a boundary wall portion that partitions the adjacent dwelling units X1 and X2. Note that the wall portion 15 corresponds to the "first wall portion", and the room 11 corresponds to the "indoor space".

[0027] The wall portion 15 has a first wall portion 18 and a second wall portion 19 adjacent to each other in the wall width direction. The thickness of the second wall portion 19 is larger than the thickness of the first wall portion 18. The first wall portion 18 is provided between each room 11, 12 of the dwelling unit X1 and partitions these rooms 11, 12. Further, the second wall portion 19 is provided between the room 11 of the dwelling unit X1 and the room 13 of the dwelling unit X2 and partitions the rooms 11, 13 of these dwelling units X1, X2 from each other. In this case, the first wall portion 18 can be referred to as a partition portion, and the second wall portion 19 can be referred to as a boundary wall portion. Also, in the second wall portion 19, the sound insulation performance is enhanced by the larger thickness than the first wall portion 18.

[0028] The wall portion 15 has a pair of inner wall portions 21, 22 facing each other and a wall frame 23 provided between the inner wall portions 21, 22. The inner wall portion 21 faces the room 11, and the inner wall portion 22 faces each of the rooms 12, 13. The wall frame 23 is formed by connecting vertical bars 23a and horizontal bars 23b in a rectangular frame shape. The inner wall portions 21, 22 are fixed to the wall frame 23.

[0029] Each of the inner wall portions 21, 22 has the same configuration. Specifically, each of the inner wall portions 21, 22 has a configuration that is symmetric with respect to each other in the thickness direction of the wall portion 15. Therefore, hereinafter, the configuration of the inner wall portion 21 will be described, and the description of the configuration of the inner wall portion 22 will be omitted. The inner wall portion 21 has an inner wall panel portion 25 and an outer wall panel portion 26 provided so as to overlap the surface (the plate surface on the room 11 side) of the inner wall panel portion 25. Both the inner wall panel portion 25 and the outer wall panel portion 26 are formed of gypsum boards. Also, the inner wall panel portion 25 and the outer wall panel portion 26 have the same plate thickness.

[0030] The outer wall panel portion 26 is disposed only in a part of the inner wall panel portion 25 in the wall width direction. Specifically, the outer wall panel portion 26 is disposed only in the second wall portion 19 of the wall portion 15. In this case, in the first wall portion 18, the inner wall portion 21 is formed only by the inner wall panel portion 25, and in the second wall portion 19, the inner wall portion 21 is formed by the inner wall panel portion 25 and the outer wall panel portion 26.

[0031] The first wall portion 18 has a wall surface 18a facing the room 11. The wall surface 18a is formed by a region of the surface of the inner wall panel portion 25 where the outer wall panel portion 26 is not overlapped. Further, the second wall portion 19 has a wall surface 19a facing the room 11. The wall surface 19a is formed by the surface of the outer wall panel portion 26 (the plate surface on the room 11 side). In this case, each of the wall surfaces 18a, 19a serves as the wall surfaces 18a, 19a of the wall portion 15. Note that the wall surface 18a corresponds to the "first wall surface", and the wall surface 19a corresponds to the "second wall surface".

[0032] The end face of the outer wall panel portion 26 on the wall surface 18a side serves as a stepped surface 28 that creates a step between each of the wall surfaces 18a, 19a. The stepped surface 28 is located at the boundary between the first wall portion 18 and the second wall portion 19 and is continuous with the wall surfaces 18a, 19a of those respective wall portions 18, 19. In this case, each of the wall surfaces 18a, 19a is continuous via the stepped surface 28. Also, the width of the stepped surface 28 is the same as the plate thickness of the outer wall panel portion 26.

[0033] Baseboards 31 - 33 are provided along the lower ends of the wall surfaces 18a, 19a of the wall portion 15. Hereinafter, in addition to FIG. 1, the configuration of the baseboards 31 - 33 will be described based on FIG. 2. FIG. 2 is a perspective view showing the baseboards 31 - 33 attached to the wall surfaces 18a, 19a of the wall portion 15. Also, in FIG. 1, the baseboards 31 - 33 are shown in a state of being viewed from above. Note that the baseboards 31 - 33 correspond to the "molding materials".

[0034] As shown in FIGS. 1 and 2, among the baseboards 31 - 33, there are a first baseboard 31 provided along the wall surface 18a of the wall portion 15, a second baseboard 32 provided along the wall surface 19a of the wall portion 15, and a third baseboard 33 provided across each of the wall surfaces 18a, 19a of the wall portion 15. Each of the baseboards 31 - 33 is formed of a resin material or a wood material. The third baseboard 33 is disposed between the first baseboard 31 and the second baseboard 32 and is adjacent to each of those baseboards 31, 32 respectively.

[0035] In addition, for the sake of convenience, FIG. 2 shows the first crosspiece 31 and the second crosspiece 32 separated from the third crosspiece 33. Also, the first crosspiece 31 corresponds to the "first cut-off material", the second crosspiece 32 corresponds to the "second cut-off material", and the third crosspiece 33 corresponds to the "third cut-off material".

[0036] The first crosspiece 31 extends linearly along the wall surface 18a of the wall portion 15. The first crosspiece 31 is fixed to the wall surface 18a with an adhesive or the like. Also, the second crosspiece 32 extends linearly along the wall surface 19a of the wall portion 15. The second crosspiece 32 is fixed to the wall surface 19a with an adhesive or the like.

[0037] The third crosspiece 33 has a stepped shape along the wall surface 18a, the stepped surface 28, and the wall surface 19a of the wall portion 15 in a plan view. In this case, the third crosspiece 33 is substantially Z-shaped in a plan view. The first portion 35 of the third crosspiece 33 along the wall surface 18a is fixed to the wall surface 18a with an adhesive or the like. Also, the second portion 36 of the third crosspiece 33 along the wall surface 19a is fixed to the wall surface 19a with an adhesive or the like.

[0038] Both the first portion 35 and the second portion 36 have a length in the wall width direction that is twice or more the width of the stepped surface 28. The cross-sectional shape of the first portion 35 (specifically, the shape of the cross-section orthogonal to the wall width direction. The same applies hereinafter) is the same as the cross-sectional shape of the first crosspiece 31. Also, the cross-sectional shape of the second portion 36 is the same as the cross-sectional shape of the second crosspiece 32.

[0039] According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

[0040] In the wall portion 15, since the second wall portion 19 projects toward the room 11 side more than the first wall portion 18, a stepped surface 28 is formed at the boundary between the wall portions 18 and 19, and the wall surfaces 18a and 19a of the wall portions 18 and 19 are continuous via the stepped surface 28. Then, baseboards 31 to 33 are provided along the lower end portions of the wall surfaces 18a and 19a having such a step. The baseboards 31 to 33 include a first baseboard 31 provided along the wall surface 18a, a second baseboard 32 provided along the wall surface 19a, and a third baseboard 33 provided across the wall surfaces 18a and 19a. The third baseboard 33 is adjacent to the first baseboard 31 and the second baseboard 32, respectively. In this case, a continuous baseboard structure can be constructed by the baseboards 31 to 33 without creating a gap between the first baseboard 31 and the second baseboard 32. Further, the third baseboard 33 has a stepped shape along the wall surface 18a, the stepped surface 28, and the wall surface 19a in plan view. In this case, a baseboard structure adapted to the step between the wall surfaces 18a and 19a can be constructed. Therefore, it is possible to suppress the appearance from being impaired.

[0041] Also, the third baseboard 33 can be attached by fixing a first portion 35 along the wall surface 18a of the third baseboard 33 to the wall surface 18a and fixing a second portion 36 along the wall surface 19a of the third baseboard 33 to the wall surface 19a. Since the wall surfaces 18a and 19a are wide surfaces unlike the stepped surface 28, the third baseboard 33 can be attached in a stable state in this case.

[0042] In the first wall portion 18, the inner wall portion 21 has a single-layer structure of only the inner side wall plate portion 25, and the wall surface 18a is formed by the surface of the inner side wall plate portion 25. Further, in the second wall portion 19, the inner wall portion 21 has a two-layer structure of the inner side wall plate portion 25 and the outer side wall plate portion 26, and the wall surface 19a is formed by the surface of the outer side wall plate portion 26. In this case, a stepped surface 28 is formed by the end surface on the wall surface 18a side of the outer side wall plate portion 26. With such a configuration, a step corresponding to the plate thickness of the outer side wall plate portion 26 occurs between the wall surfaces 18a and 19a. And in the above-described embodiment, the skirting structure described above is applied to such a configuration. Thereby, when attaching the skirting 31 to 33 to the wall surfaces 18a and 19a where a small step such as a step corresponding to the plate thickness occurs, it is possible to attach the skirting 31 to 33 in a stable state while suppressing the appearance from being impaired.

[0043] Regarding both the first portion 35 along the wall surface 18a and the second portion 36 along the wall surface 19a in the third skirting 33, the length in the wall width direction is larger than twice the width of the stepped surface 28. Thereby, the first portion 35 can be fixed to the wall surface 18a in a stable state, and the second portion 36 can be fixed to the wall surface 19a in a stable state. As a result, the third skirting 33 can be attached in an even more stable state.

[0044] [Second Embodiment] Next, a second embodiment will be described. In this embodiment, the building 40 is a unit-type building formed by combining a plurality of rectangular parallelepiped building units 41. Therefore, first, an overview of such a building 40 will be described based on FIGS. 3 and 4. FIG. 3 is a perspective view showing the building unit 41.

[0045] As shown in Fig. 3, the building unit 41 includes four columns 42 arranged at its four corners, and four ceiling girders 43 and four floor girders 44 that connect the upper and lower ends of each column 42 respectively. The column 42 is made of square tubular steel, and the ceiling girder 43 and the floor girder 44 are made of channel steel with a U-shaped cross-section. A plurality of ceiling joists 45 are spanned between the ceiling girders 43 on the long side, and a plurality of floor joists 46 are spanned between the floor girders 44 on the long side. The ceiling surface material 47 is supported by each ceiling joist 45, and the floor surface material 48 is supported by each floor joist 46.

[0046] As shown in Fig. 4, the building 40 is composed of a plurality of building units 41 arranged side by side in the horizontal direction. In the building 40, a column assembly part 51 where the columns 42 of the four building units 41 gather is provided. Hereinafter, the structure around the column assembly part 51 will be described based on Fig. 5. Note that Fig. 5 is a cross-sectional view showing a decorative column 53 configured to include the column assembly part 51 and each wall part 61, 62 provided adjacent to the decorative column 53.

[0047] As shown in Fig. 5, the building 40 is provided with a decorative column 53.

Also, the wall portion 62 is arranged in a state where the end portion in the wall width direction is in contact with the second outer surface 58b of the outer decorative panel portion 56. In this case, the wall portions 61, 62 are arranged so as to be perpendicular to each other. Note that the wall portion 61 corresponds to the "second wall portion", and the wall portion 62 corresponds to the "third wall portion".

[0051] The building 40 is provided with a plurality of rooms 64, 65. Each of the rooms 64, 65 is, for example, a living room. However, the rooms 64, 65 may be non-living rooms. Each of the rooms 64, 65 is partitioned by the wall portions 61, 62. The room 64 is provided on the inner corner side of each of the wall portions 61, 62, and the room 65 is provided on the side opposite to the room 64 with the wall portions 61, 62 interposed therebetween. Also, the room 65 is formed so as to straddle each of the wall portions 61, 62. Note that the room 64 corresponds to the "indoor space".

[0052] The wall portion 61 has a pair of wall plate portions 67 and 68 facing each other, and a wall frame 69 provided between the wall plate portions 67 and 68. Each of the wall plate portions 67 and 68 is formed of a gypsum board. Among the wall plate portions 67 and 68, the wall plate portion 67 faces the room 64, and the wall plate portion 68 faces the room 65. The wall frame 69 is formed by connecting a vertical rail 69a and a horizontal rail 69b in a rectangular frame shape. Each of the wall plate portions 67 and 68 is fixed to the wall frame 69.

[0053] The wall portion 62 has a pair of wall plate portions 71 and 72 facing each other, and a wall frame 73 provided between the wall plate portions 71 and 72. Each of the wall plate portions 71 and 72 is formed of a gypsum board. Among the wall plate portions 71 and 72, the wall plate portion 71 faces the room 64, and the wall plate portion 72 faces the room 65. The wall frame 73 is formed by connecting a vertical rail 73a and a horizontal rail 73b in a rectangular frame shape. Each of the wall plate portions 71 and 72 is fixed to the wall frame 73.

[0054] Here, in the building 40, a module design is adopted. Hereinafter, the positional relationship between each of the wall portions 61 and 62 with respect to the decorative column 53 due to the module design will be described.

[0055] The wall portion 61 has a wall surface 61a facing the room 64. The wall surface 61a is formed by the wall plate portion 67. The wall portion 61 is arranged in a state where the wall surface 61a is positioned on the same plane as the second outer surface 57b of the inner decorative plate portion 55. Note that the wall surface 61a corresponds to the "first wall surface". Further, the wall portion 62 has a wall surface 62a facing the room 64. The wall surface 62a is formed by the wall plate portion 71. The wall portion 62 is arranged in a state where the wall surface 62a is positioned on the same plane as the first outer surface 57a of the inner decorative plate portion 55. Note that the wall surface 62a corresponds to the "second wall surface".

[0056] Since the wall portions 61 and 62 are arranged in the above-described positional relationship with respect to the decorative column 53, the corner portion 75 between the first outer surface 58a and the second outer surface 58b of the outer decorative panel portion 56 protrudes toward the room 64 side from between the wall surfaces 61a and 62a of the wall portions 61 and 62. In this case, each side surface of the protruding portion 76 protruding at the corner portion 75 is a first stepped surface 78 and a second stepped surface 79, respectively. The first stepped surface 78 is continuous with the wall surface 61a of the wall portion 61, and the second stepped surface 79 is continuous with the wall surface 62a of the wall portion 62. In this case, the wall surfaces 61a and 62a of the wall portions 61 and 62 are continuous via the first stepped surface 78 and the second stepped surface 79.

[0057] Baseboards 81 to 83 are provided along the lower ends of the wall surfaces 61a and 62a of the wall portions 61 and 62. Hereinafter, the configuration of the baseboards 81 to 83 will be described with reference to FIG. 6 in addition to FIG. 5. FIG. 6 is a perspective view showing the baseboards 81 to 83 attached to the wall surfaces 61a and 62a of the wall portions 61 and 62. In FIG. 5, the baseboards 81 to 83 are shown in a state of being viewed from above. Note that the baseboards 81 to 83 correspond to "lumber for division".

[0058] As shown in FIGS. 5 and 6, the baseboards 81 to 83 include a first baseboard 81 provided along the wall surface 61a of the wall portion 61, a second baseboard 82 provided along the wall surface 62a of the wall portion 62, and a third baseboard 83 provided across the wall surfaces 61a and 62a of the wall portions 61 and 62. Each of the baseboards 81 to 83 is formed of a resin material or a wood material. The third baseboard 83 is disposed between the first baseboard 81 and the second baseboard 82 and is adjacent to each of the baseboards 81 and 82.

[0059] In FIG. 6, for convenience, the first baseboard 81 and the second baseboard 82 are shown in a state of being separated from the third baseboard 83. The first baseboard 81 corresponds to the "first lumber for division", the second baseboard 82 corresponds to the "second lumber for division", and the third baseboard 83 corresponds to the "third lumber for division".

[0060] The third crosspiece 83 has a stepped shape along the wall surface 61a of the wall portion 61, the first stepped surface 78, the second stepped surface 79, and the wall surface 62a of the wall portion 62, respectively, in a plan view. In this case, the third crosspiece 83 has a substantially W shape in a plan view. A first portion 85 along the wall surface 61a in the third crosspiece 83 is fixed to the wall surface 61a by an adhesive or the like. Also, a second portion 86 along the wall surface 62a in the third crosspiece 83 is fixed to the wall surface 62a by an adhesive or the like.

[0061] Both the first portion 85 and the second portion 86 have a length in the wall width direction that is twice or more the width of each of the stepped surfaces 78, 79. The cross-sectional shape of the first portion 85 (specifically, the shape of a cross-section orthogonal to the wall width direction of the wall portion 61. The same applies hereinafter.) is the same as the cross-sectional shape of the first crosspiece 81. Also, the cross-sectional shape of the second portion 86 (specifically, the shape of a cross-section orthogonal to the wall width direction of the wall portion 62. The same applies hereinafter.) is the same as the cross-sectional shape of the second crosspiece 82.

[0062] According to the configuration of the present embodiment described in detail above, the following excellent effects can be obtained.

[0063] In the building 40 of this embodiment, due to the adoption of modular design, the corner 75 between the first outer surface 58a and the second outer surface 58b of the decorative board portion 54 (specifically, the outer decorative board portion 56) of the decorative column 53 protrudes toward the room 64 side from between the wall surfaces 61a, 62a of the respective wall portions 61, 62. And the respective wall surfaces 61a, 62a are continuous through each side surface (that is, the first stepped surface 78 and the second stepped surface 79) of the protruding portion 76. Along the lower end portions of the respective wall surfaces 61a, 62a, baseboards 81 to 83 are provided. In addition to the first baseboard 81 provided along the wall surface 61a and the second baseboard 82 provided along the wall surface 62a, the baseboards 81 to 83 include a third baseboard 83 provided across the respective wall surfaces 61a, 62a. The third baseboard 83 is adjacent to the first baseboard 81 and the second baseboard 82, respectively. In this case, a continuous baseboard structure by the respective baseboards 81 to 83 can be constructed without a gap occurring between the first baseboard 81 and the second baseboard 82. Further, the third baseboard 83 has a stepped shape along the wall surface 61a, the first stepped surface 78, the second stepped surface 79, and the wall surface 62a, respectively, in plan view. In this case, a baseboard structure adapted to the step between the respective wall surfaces 61a, 62a can be constructed. Therefore, it is possible to suppress the appearance from being impaired.

[0064] Also, the third baseboard 83 can be attached by fixing the first portion 85 along the wall surface 61a of the third baseboard 83 to the wall surface 61a and fixing the second portion 86 along the wall surface 62a of the third baseboard 83 to the wall surface 62a. Since the respective wall surfaces 61a, 62a are wide surfaces, different from the respective stepped surfaces 78, 79, in this case, the third baseboard 83 can be attached in a stable state.

[0065] In the building 40 of the above-described embodiment, since module design is adopted, the wall portion 61 is arranged with the wall surface 61a positioned on the same plane as the second outer surface 57b of the inner decorative panel portion 55, and the wall portion 62 is arranged with the wall surface 62a positioned on the same plane as the first outer surface 57a of the inner decorative panel portion 55. And by such an arrangement, the corner portion 75 of the outer decorative panel portion 56 protrudes toward the room 64 side, and the first stepped surface 78 and the second stepped surface 79 are formed by the protruding portion 76. In this case, the widths of these stepped surfaces 78 and 79 are the same as the plate thickness of the outer decorative panel portion 56. And in the above-described embodiment, the skirting structure described above is applied to such a configuration. Thereby, when a small step such as a step corresponding to the plate thickness occurs, when attaching the third skirting 83 to each of the wall surfaces 61a and 62a via the stepped surfaces 78 and 79, it is possible to attach the third skirting 83 in a stable state while suppressing damage to the appearance.
