[0010] (Embodiment) Below, a corner member and a wall structure according to one embodiment of the present invention will be described with reference to the drawings. The drawings described in the following embodiments are schematic, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios. The following embodiments and modifications are merely a part of various embodiments of the present invention. The following embodiments and modifications can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved. The configurations of the modifications can also be combined as appropriate.

[0011] 1. Overview The projecting corner member 1 of this embodiment is provided at a projecting corner portion 23 formed by the intersection of two wall surfaces 21, 22 of a building. The projecting corner member 1 comprises a pair of projecting corner pieces 11, 12 arranged along each of the two wall surfaces 21, 22. The pair of projecting corner pieces 11, 12 have a pair of inner surfaces 110, 120 facing the two wall surfaces. A space 13 is formed in at least one of the pair of inner surfaces 110, 120. The space 13 is formed so that one end 310 of a projection adjustment member 3 arranged between the pair of inner surfaces 110, 120 and the two wall surfaces 21, 22 can be inserted into the space 13.

[0012] In the wall structure 1A of this embodiment, a decorative surface material 4 is provided on wall surfaces 21, 22 of a wall base 2 of a building, and a corner material 1 is provided at a corner portion 23 where the two wall surfaces 21, 22 intersect. A projection adjustment material 3 is provided between one inner surface 110 of a pair of inner surfaces 110, 120 of the projection corner material 1 and a wall surface 21 facing this one inner surface 110, and another projection adjustment material 3 is provided between the other inner surface 120 of the pair of inner surfaces 110, 120 and a wall surface 22 facing this other inner surface 120, one end 310 of one projection adjustment material 31 of the two projection adjustment materials 3 is inserted into the space 13, the pair of projection corner pieces 11, 12 are arranged so as to follow along each of the two wall surfaces 21, 22 of the projection corner portion 23, the projection corner material 1 is fixed to the projection corner portion 23 by fixing means 5, and the decorative surface material 4 is arranged so that its end edges 41, 42 face the side surfaces 111, 121 of the pair of projection corner pieces 11, 12 and is fixed to the wall base 2 by fixing means 6.

[0013] In the projecting corner member 1 and wall structure 1A of this embodiment, the projection adjustment member 3 is positioned between the pair of inner surfaces 110, 120 and the two wall surfaces 21, 22, so that the projecting corner member 1 can be positioned with a projection allowance and away from the projecting corner portion 23. Therefore, even if the decorative surface member 4 is positioned away from the wall surfaces 21, 22 by the fixing means 6, the projection allowance of the projecting corner member 1 can be adjusted to match that position. Furthermore, because one end 310 of the projection adjustment member 3 is inserted into the space 13, the positioning of the projecting corner member 1 and the projection adjustment member 3 can be easily performed, making the projecting corner member 1 easy to install.

[0014] 2.Details FIG. 1 shows a wall structure 1A of this embodiment. This wall structure 1A is a structure for the interior wall (interior wall) of a building. The wall structure 1A comprises a protruding corner material 1, a wall base 2, a protrusion adjustment material 3, a decorative surface material 4, and fixing means 6. As shown in FIG. 2, the wall structure 1A may also comprise a baseboard 7, a trim material 8, etc. Note that, although this embodiment describes a case in which the protruding corner material 1 is applied to a wall, the protruding corner material 1 is not limited to this, and can also be applied to overhanging parts and corner parts of beams of a building.

[0015] (Extruded corner lumber) Figure 3 shows an outside corner material 1. The outside corner material 1 can be made of, for example, resin or wood. When the outside corner material 1 is made of wood, sandalwood or the like can be used as the wood in consideration of environmental friendliness. Furthermore, from the standpoint of durability, painted wood can also be used, and for example, persimmon tannin can be used.

[0016] The corner member 1 is formed long so as to extend in the vertical direction. When the corner member 1 is cut along an imaginary plane perpendicular to the longitudinal direction, the cross-sectional shape of the corner member 1 is constant over almost the entire length.

[0017] The projecting corner material 1 has a pair of projecting corner pieces 11, 12. The pair of projecting corner pieces 11, 12 are formed over the entire longitudinal length of the projecting corner material 1. When the projecting corner material 1 is constructed, the pair of projecting corner pieces 11, 12 are arranged so as to respectively follow the two intersecting wall surfaces 21, 22 of the wall base 2. For example, one projecting corner piece 11 is arranged along one wall surface 21, and the other projecting corner piece 12 is arranged along the other wall surface 22.

[0018] The pair of projecting corner pieces 11, 12 have inner surfaces 110, 120, respectively. The pair of inner surfaces 110, 120 are surfaces that face the two intersecting wall surfaces 21, 22 of the wall base 2 when the projecting corner material 1 is installed. One projecting corner piece 11 is positioned so that one inner surface 110 faces one wall surface 21. The other projecting corner piece 12 is positioned so that the other inner surface 120 faces the other wall surface 22.

[0019] The two wall surfaces 21, 22 of the wall base 2 intersect at a right angle (orthogonal). Here, "right angle" does not only mean a right angle (90°) in the strict sense, but also includes an approximately right angle that deviates slightly from 90°. The pair of inner surfaces 110, 120 intersect at approximately the same angle as the angle at which the two wall surfaces 21, 22 intersect, and when the two wall surfaces 21, 22 are orthogonal, the pair of inner surfaces 110, 120 are also orthogonal.

[0020] The pair of projected corner pieces 11, 12 have outer surfaces 112, 122, respectively. The pair of outer surfaces 112, 122 are surfaces that face away from the two wall surfaces 21, 22 when the projected corner material 1 is constructed, and constitute the outer surfaces of the projected corner material 1. One outer surface 112 is the surface that faces one inner surface 110. The other outer surface 122 is the surface that faces the other inner surface 120. Each of the pair of outer surfaces 112, 122 is formed flat. The pair of outer surfaces 112, 122 are perpendicular to each other, and a chamfered portion 14 is formed at the intersection.

[0021] The pair of projecting corner pieces 11, 12 have side surfaces 111, 121, respectively. The pair of side surfaces 111, 121 are surfaces that face the end edges (end faces) 41, 42 of the decorative facing material 4 applied to the two wall surfaces 21, 22 when the projecting corner material 1 is installed. One side surface 111 is a surface that faces the end edge 41 of the decorative facing material 4 applied to one wall surface 21. The other side surface 121 is a surface that faces the end edge 42 of the decorative facing material 4 applied to the other wall surface 22. One side surface 111 is formed between one outer surface 112 and one inner surface 110, and is positioned opposite the other outer surface 122. The other side surface 121 is formed between the other outer surface 122 and the other inner surface 120, and is positioned opposite the one outer surface 112.

[0022] The projecting corner material 1 has a space 13. The space 13 is formed at the base of the other projecting corner piece 12 (at the boundary with one projecting corner piece 11). The space 13 is recessed into the other inner surface 120 to form a groove. The space 13 is formed over the entire length of the projecting corner material 1 in the longitudinal direction. The space 13 may also be formed at the base of one projecting corner piece 11 (at the boundary with the other projecting corner piece 12). In this case, the space 13 is recessed into one inner surface 110 to form a groove. The space 13 may be formed only in one projecting corner piece 11, only in the other projecting corner piece 12, or in both projecting corner pieces 11, 12.

[0023] The projected corner material 1 has a pair of grooves 15, 16. Each of the pair of grooves 15, 16 is formed over the entire length of the projected corner material 1 in the longitudinal direction. One groove 15 is formed in one projected corner piece 11. One groove 15 is recessed into one side surface 111 to form a groove shape. The other groove 16 is formed in the other projected corner piece 12. The other groove 16 is recessed into the other side surface 121 to form a groove shape.

[0024] (wall base) The wall base 2 is a base for constructing a wall by attaching the decorative surface material 4 and other accessories. In this embodiment, the wall base 2 includes a framework 24 and surface materials 25 and 26. The framework 24 is a base for attaching the surface material 25, and can be formed, for example, from multiple steel frames such as LGS (Light Gauge Steel).

[0025] The face plates 25, 26 are members that make up the wall surfaces 21, 22 of the wall base 2, and are rectangular flat plates, and can be made of, for example, plywood or gypsum board. In this embodiment, one wall surface 21 is formed on the outer surface (the surface opposite the framework 24) of one face plate 25, and the other wall surface 22 is formed on the outer surface (the surface opposite the framework 24) of the other face plate 26. A protruding corner 23 is formed at the joint between one face plate 25 and the other face plate 26. In this embodiment, one face plate 25 is disposed so as to overhang the other face plate 26. Therefore, the protruding corner 23 is formed at the corner of one face plate 25.

[0026] (Protrusion adjustment material) The projection adjustment member 3 is a member provided to space the corner member 1 away from the wall surfaces 21, 22. The projection adjustment member 3 is formed of a rectangular flat plate, for example, made of medium density fiberboard (MDF) or the like. The projection adjustment member 3 is formed to extend in the vertical direction, and has a length approximately equal to the longitudinal direction of the corner member 1. The projection adjustment member 3 is formed so that one end can be inserted into the space 13 of the corner member 1. Therefore, the projection adjustment member 3 has thickness and width dimensions that allow it to be inserted into the space 13. The thickness of the projection adjustment member 3 can adjust the projection of the corner member 1 from the wall surfaces 21, 22. When the thickness of the projection adjustment member 3 is increased, the projection of the corner member 1 increases, and when the thickness of the projection adjustment member 3 is decreased, the projection of the corner member 1 decreases.

[0027] (decorative surface material) 4, the decorative surface material 4 is a component that constitutes the exterior of the wall structure 1A and is made of, for example, a ceramic material, a metal material, or a wood material. The decorative surface material 4 is formed into a flat plate that is approximately rectangular when viewed from the front, and by providing multiple decorative surface materials 4 on the wall surfaces 21 and 22, the outer surface of the wall structure 1A can be formed.

[0028] The decorative surface material 4 has a receiving portion 43. The receiving portion 43 is formed over the entire length at one end of the decorative surface material 4. The decorative surface material 4 also has a protruding portion 44. The protruding portion 44 is formed over the entire length at the other end of the decorative surface material 4. The receiving portion 43 and the protruding portion 44 are formed in positions facing each other. Behind the protruding portion 44, a locking portion 45 is formed over the entire length at the other end of the decorative surface material 4. The two end faces 46 of the decorative surface material 4 that do not have the receiving portion 43 and the protruding portion 44 are formed flat.

[0029] The decorative surface material 4 can be used for both horizontal and vertical installation. For horizontal installation, the decorative surface material 4 is installed with the receiving portion 43 and the protruding portion 44 extending horizontally (left and right). For vertical installation, the decorative surface material 4 is installed with the receiving portion 43 and the protruding portion 44 extending vertically. Figure 1 shows the state in which the decorative surface material 4 is installed horizontally. In this case, the end face 46 of the decorative surface material 4 is formed as end edges (end faces) 41, 42 that face the pair of side faces 111, 121 of the corner material 1.

[0030] (Fixing means) The fixing means 6 is a member that fixes the decorative surface material 4 to the wall base 2. A metal fastener can be used as the fixing means 6. This fastener is provided with a locking piece that can be hooked onto the receiving portion 43 and the protruding portion 44. The locking piece is hooked onto the receiving portion 43 and the protruding portion 44, and the fastener is fixed to the wall base 2 with a fixing device 61 such as a screw or nail. In this way, the decorative surface material 4 can be fixed to the wall base 2.

[0031] (Installation method for corner members using projection adjustment materials) In the wall structure 1A of this embodiment, the projection corner member 1 can be constructed using the projection adjustment member 3 as follows. When the projection corner member 1 is constructed using the projection adjustment member 3, the step between the outer surfaces 112, 122 of the projection corner member 1 and the outer surface of the decorative facing member 4 (the surface opposite the wall base 2) can be reduced. For example, when the decorative facing member 4 is placed on the wall surfaces 21, 22 using fasteners as the fixing means 6, a gap equivalent to the thickness of the fastener fixing portion may be formed between the decorative facing member 4 and the wall surfaces 21, 22, resulting in a large step between the outer surfaces 112, 122 of the projection corner member 1 and the outer surface of the decorative facing member 4. Therefore, by adjusting the projection of the projection corner member 1 using the projection adjustment member 3, the step between the outer surfaces 112, 122 of the projection corner member 1 and the outer surface of the decorative facing member 4 can be reduced.

[0032] First, as shown in FIG. 5A, a projection adjustment member 3 is attached to the projecting corner member 1. This projection adjustment member 3 is a projection adjustment member 31 that is placed between one inner surface 110 of the projecting corner member 1 and one wall surface 21 of the wall base 2. One end 310 of the projection adjustment member 31 is inserted into the space 13. The projection adjustment member 31 is fixed to one of the projecting corner pieces 11 with a fastener 51. The fastener 51 is an elongated fixing means such as a pin nail or a finish nail. The projection adjustment member 31 is also bonded to one of the inner surfaces 110 with adhesive 91. The projection adjustment member 31 protrudes outward beyond one side surface 111.

[0033] The other projection adjustment material 3, a projection adjustment material 32, is attached to the other wall surface 22 of the wall base 2. The projection adjustment material 32 is fixed with fasteners 52 such as pin nails or finish nails. The projection adjustment material 32 is also adhered to the other inner surface 120 with adhesive 92. One end face of the projection adjustment material 32 does not protrude beyond the protruding corner portion 23 and is positioned so as to be aligned with one wall surface 21.

[0034] Next, as shown in Figure 5B, one of the projection adjustment members 31 is attached to the wall base 2. One of the projection adjustment members 31 is placed along one of the wall surfaces 21. One of the projection adjustment members 31 is fixed to the face material 25 with fasteners 58 such as pin nails or finish nails. One of the projection adjustment members 31 is also adhered to one of the wall surfaces 21 with adhesive 93. The inner surface 120 of the other projection corner piece 12 of the projection corner member 1 is also adhered to the outer surface of the other projection adjustment member 32 (the surface opposite the wall surface 22) with adhesive 93.

[0035] In this way, the projecting corner member 1 is arranged so that the pair of projecting corner pieces 11, 12 are aligned along the two wall surfaces 21, 22, respectively. A projection adjustment member 31 is provided between one inner surface 110 and the wall surface 21 facing this inner surface 110. Another projection adjustment member 32 is provided between the other inner surface 120 and the wall surface 22 facing this other inner surface 120. One end 310 of the projection adjustment member 31, arranged between one inner surface 110 and one wall surface 21, is inserted into the space 13. The projecting corner member 1 is fixed to the projecting corner portion 23 via the projection adjustment member 31 by fasteners 51, 58 and adhesives 91, 93, which are fixing means 5. In this way, one end 310 of the projection adjustment member 31 can be inserted into the space 13 without interference between one projection adjustment member 31 and the other projection adjustment member 32.

[0036] Next, as shown in Figure 5C, adhesives 94, 95 are applied to side surfaces 111, 121 of the corner member 1. At this time, some of the adhesives 94, 95 also flow into grooves 15, 16. Fixing means 6 are provided on wall surfaces 21, 22. Fixing means 6 are provided at lateral positions on the end of projection adjustment member 31 opposite the corner member 1, and at lateral positions on the end of projection adjustment member 32 opposite the corner member 1. Note that although the fixing means 6 is shown simplified in Figure 5C, it is a fastener similar to the fixing means 6 shown in Figure 1.

[0037] Next, as shown in FIG. 5D , multiple decorative facing materials 4 are arranged. The decorative facing materials 4 are attached to fixing means 6 and fixed to the wall base 2. The back surfaces of the decorative facing materials 4 are arranged facing the wall surfaces 21 and 22, and the front surfaces (decorative surfaces) are exposed to the outer surface of the wall structure 1A. One decorative facing material 4 has its end portion on the side of the projected corner material 1 arranged on the front surface side of one of the projection adjustment materials 31. The edge 41 of one decorative facing material 4 is arranged facing one side surface 111 of the projected corner material 1, and the edge 41 and side surface 111 are bonded together with adhesive 94. The other decorative facing material 4 has its end portion on the side of the projected corner material 1 arranged on the front surface side of the other projection adjustment material 32. The edge 42 of the other decorative facing material 4 is arranged facing the other side surface 121 of the projected corner material 1, and the edge 42 and side surface 121 are bonded together with adhesive 95.

[0038] In this manner, the corner member 1 and the decorative surface member 4 of the wall structure 1A of this embodiment are constructed.

[0039] It is desirable to apply adhesives 94 and 95 so that they do not spill out onto the surface side from the bonding surfaces between edge 41 and side surface 111 and between edge 42 and side surface 121. Furthermore, the formation of grooves 15 and 16 makes it difficult for adhesives 94 and 95 to spill out onto the surface side.

[0040] (Installation method for baseboards and trim boards when installing corner boards using projection adjustment materials) Figures 6A and 6B show baseboard 7 used in wall structure 1A of this embodiment. Baseboard 71 shown in Figure 6A is a long member formed so as to extend in the left-right direction, and has a cross section that is approximately rectangular when cut on an imaginary plane perpendicular to the long direction. The four corners of baseboard 71 are chamfered. Baseboard 72 shown in Figure 6B is a long member formed so as to extend in the left-right direction, and has a cross section that is approximately square when cut on an imaginary plane perpendicular to the long direction. The four corners of baseboard 72 are chamfered. Both baseboards 71 ​​and 72 can be made of the same wood as the corner material 1.

[0041] Figure 7A shows the construction structure when using the baseboard 71 of Figure 6A. This decorative surface material 4 is installed vertically, with the end face 46 forming the lower end face. A spacer 47 is provided between the decorative surface material 4 and the wall surfaces 21, 22. The baseboard 71 is installed below the decorative surface material 4. The upper face of the baseboard 71 contacts the lower end face (end face 46) of the decorative surface material 4. The lower face of the baseboard 71 contacts the floor surface 27.

[0042] Spacers 73 are provided between baseboard 71 and wall surfaces 21, 22. Spacers 73 have approximately the same thickness as spacers 47, and are fixed to surface materials 25, 26 with fasteners 731 such as screws. The back surfaces of spacers 73 are bonded to wall surfaces 21, 22 with adhesive 732. The back surface of baseboard 71 is then bonded and fixed to the surface of spacer 73 with adhesive 74.

[0043] Figure 7B shows the construction structure when the baseboard 71 of Figure 6A is used. This decorative surface material 4 is constructed by laying it horizontally, and the lower end surface is formed by the protruding portion 44. A starter 48 is provided between the decorative surface material 4 and the wall surfaces 21, 22, and the hook piece 481 of the starter 48 is hooked onto the locking portion 45 of the decorative surface material 4 to attach the decorative surface material 4. The baseboard 71 is provided below the decorative surface material 4. The upper surface of the baseboard 71 is in contact with the lower end surface of the decorative surface material 4 (the lower surface of the protruding portion 44). Otherwise, the construction structure of the baseboard 71 is the same as in Figure 7A. .

[0044] Figure 8A shows the construction structure when using baseboard 72 in Figure 6B. Baseboard 72 has a smaller vertical dimension than baseboard 71, and is therefore used when it is desired to reduce the dimension between floor surface 27 and the underside of decorative surface material 4. The construction structure in Figure 8A is formed in the same way as Figure 7A, except that baseboard 72 is used and spacer 73 is fixed only with adhesive 732 without using fixing tool 731.

[0045] Figure 8B shows an installation structure when using baseboard 72 of Figure 6B. The installation structure of Figure 8B is formed in the same manner as Figure 7B, except for the structure using baseboard 72 and the structure in which spacer 73 is fixed only with adhesive 732 without using fixing tool 731.

[0046] 9A and 9B show a parting material 8 used in the wall structure 1A of this embodiment. The parting material 81 shown in FIG. 9A is a long member formed so as to extend in the left-right or up-down direction. The parting material 81 comprises a main body portion 83 and a cover portion 84. The main body portion 83 has a cross section that is approximately rectangular when cut along an imaginary plane perpendicular to the longitudinal direction. The cover portion 84 is provided so as to protrude from a position closer to the front of one surface of the main body portion 83. The parting material 82 shown in FIG. 9B is formed so that the dimension of the main body portion 83 in the front-to-back direction is smaller than that of FIG. 9A. The parting material 81 is used in the wall structure 1A when the projection adjustment material 3 is used, and the parting material 81 is used in a wall structure when the projection adjustment material 3 is not used.

[0047] FIG. 10A shows an inside corner of a wall structure 1A using a trim 81 shown in FIG. 9A. A pair of decorative panelings 29, 33 are attached to wall surfaces 21, 22 via spacers 28. An end face 291 of one decorative paneling 29 faces a surface 331 of the other decorative paneling 33, and the trim 81 is disposed between the end face 291 and the surface 331. One surface of a main body 83 of the trim 81 contacts the end face 291, and the other surface of the main body 83 of the trim 81 contacts the surface 331. The rear surface of the main body 83 is bonded to the wall surface 21 with adhesive 55. A fastener 56, such as a pin nail or a finish nail, is driven into the front surface of the main body 83, fixing the trim 81 to the panel 25 that constitutes the wall surface 21. The front corner of one decorative paneling 29 is covered by a cover portion 84 of the trim 81.

[0048] FIG. 10B shows the upper part of a wall structure 1A using the parting strip 81 shown in FIG. 9A. A decorative surface material 29 is attached to the wall surface 21 via a spacer 28. An upper end surface 292 of the decorative surface material 29 faces an underside 341 of the ceiling material 34, and the parting strip 81 is disposed between the upper end surface 292 and the underside 341. The underside of the main body 83 of the parting strip 81 contacts the upper end surface 292, and the upper surface of the main body 83 of the parting strip 81 contacts the underside 341. The rear surface of the main body 83 is bonded to the wall surface 21 with adhesive 55. The parting strip 81 is fixed to the ceiling material 34 by driving fasteners 56, such as pin nails or finish nails, into the front surface of the main body 83. The front corners of the decorative surface material 29 are covered by a cover portion 84 of the parting strip 81.

[0049] Figure 10C shows the upper part of a wall structure 1A using the parting material 81 shown in Figure 9A. A decorative surface material 29 is attached to the wall surface 21 via a spacer 28. The parting material 81 is disposed on an upper end surface 292 of the decorative surface material 29. The lower surface of a main body 83 of the parting material 81 is in contact with the upper end surface 292. The rear surface of the main body 83 is adhered to the wall surface 21 with adhesive 55. Fixing devices 56, such as pin nails or finish nails, are driven into the upper surface of the main body 83, fixing the parting material 81 to the surface material 25 that constitutes the wall surface 21. The front corners of the decorative surface material 29 are covered by a cover portion 84 of the parting material 81.

[0050] The parting material 81 can be installed between the wall surfaces 21, 22 and the ceiling surface (not shown).

[0051] (Installation method for corner members when not using projection adjustment members) The projecting corner material 1 of this embodiment can be installed without using the projection adjustment material 3. When the decorative surface material 4 is placed on the wall surfaces 21, 22 without using fasteners as the fixing means 6, a large step is unlikely to occur between the outer surfaces 112, 122 of the projecting corner material 1 and the outer surface of the decorative surface material 4. Therefore, the projecting corner material 1 can be installed without using the projection adjustment material 3 and adjusting the projection of the projecting corner material 1.

[0052] 11A, adhesive 96 is applied to a pair of inner surfaces 110, 120 of the corner member 1. A portion of the adhesive 96 also flows into the space 13.

[0053] Next, the projected corner member 1 is placed in the projected corner portion 23. Here, one projected corner piece 11 of the projected corner member 1 is placed along one wall surface 21, and the other projected corner piece 12 of the projected corner member 1 is placed along the other wall surface 22. One inner surface 110 of the projected corner member 1 is placed facing one wall surface 21 and bonded thereto with adhesive 96. The other inner surface 120 of the projected corner member 1 is placed facing the other wall surface 22 and bonded thereto with adhesive 96. Next, fasteners 57, which serve as fixing means 5, are driven from the inner surfaces of the grooves 15 and 16 of the projected corner member 1 into the face materials 25 and 26 that make up the wall surfaces 21 and 22, thereby fixing the pair of projected corner pieces 11 and 12 to the face materials 25 and 26. The fasteners 57 are elongated fixing means such as pin nails or finish nails.

[0054] 11C, adhesives 94 and 95 are applied to the side surfaces 111 and 121 of the corner member 1. At this time, some of the adhesives 94 and 95 also flow into the grooves 15 and 16.

[0055] Next, as shown in Figure 11D, multiple decorative facing materials 4 are arranged. The decorative facing materials 4 are fixed to the wall base 2 without using fixing means 6. The back surfaces of the decorative facing materials 4 are arranged facing the wall surfaces 21, 22, and the front surfaces (decorative surfaces) are exposed. The edge 41 of one of the decorative facing materials 4 is arranged facing one side surface 111 of the corner member 1, and the edge 41 and side surface 111 are bonded together with adhesive 94. The edge 42 of the other decorative facing material 4 is arranged facing the other side surface 121 of the corner member 1, and the edge 42 and side surface 121 are bonded together with adhesive 95.

[0056] In this way, the corner material 1 and the decorative surface material 4 are installed.

[0057] (Installation method for baseboards and trimmings when installing corner boards without using projection adjustment materials) When a corner material is installed without using a projection adjustment material, in Figures 7A and 7B and Figures 8A and 8B, the decorative surface material 4 is installed without using spacers 47 or starters 48, and the baseboard 7 is installed without using spacers 73.

[0058] Figure 12A shows the construction structure when the baseboard 71 of Figure 6A is used. This decorative surface material 4 is installed vertically, with the end face 46 forming the lower end face. The decorative surface material 4 is in contact with and directly fixed to the wall faces 21 and 22. The baseboard 71 is provided below the decorative surface material 4. The upper face of the baseboard 71 is in contact with the lower end face (end face 46) of the decorative surface material 4. The lower face of the baseboard 71 is in contact with the floor surface 27. The baseboard 71 is in contact with and fixed to the wall faces 21 and 22. The back side of the baseboard 71 is bonded and fixed to the wall faces 21 and 22 with adhesive 75.

[0059] Figure 12B shows the construction structure when the baseboard 71 of Figure 6A is used. This decorative surface material 4 is constructed horizontally, with the lower end surface formed by the protruding portion 44. The decorative surface material 4 is in contact with and directly fixed to the wall surfaces 21 and 22. The baseboard 71 is provided below the decorative surface material 4. The upper surface of the baseboard 71 is in contact with the lower end surface of the decorative surface material 4 (the lower surface of the protruding portion 44). Otherwise, the construction structure of the baseboard 71 is the same as in Figure 12A.

[0060] Fig. 13A shows a construction structure using baseboard 72 of Fig. 6B. Baseboard 72 is formed in the same manner as in Fig. 12A, except that it is smaller in size in the vertical direction than baseboard 71.

[0061] Fig. 8B shows a construction structure in which the baseboard 72 in Fig. 6B is used. The construction structure in Fig. 8B is formed in the same manner as Fig. 12B, except that the baseboard 72 is used.

[0062] Figure 14A shows an inside corner portion of a wall structure using the trim 82 shown in Figure 9B. A pair of decorative surface materials 29, 33 are directly fixed to wall surfaces 21, 22. Except for the fact that the pair of decorative surface materials 29, 33 are directly fixed to wall surfaces 21, 22 without spacers 28, and the fact that the trim 82 is used, the construction structure of Figure 14A is formed in the same manner as the construction structure of Figure 10A.

[0063] Figure 14B shows the upper part of a wall structure using the parting material 82 shown in Figure 9B. A decorative surface material 29 is directly fixed to the wall surface 21. Except for the fact that the decorative surface material 29 is directly fixed to the wall surface 21 without the intermediary of a spacer 28 and that a parting material 82 is used, the construction structure of Figure 14B is formed in the same manner as the construction structure of Figure 10B.

[0064] Figure 14C shows the upper part of a wall structure using the trim material 82 shown in Figure 9B. A decorative surface material 29 is directly fixed to the wall surface 21. Except for the fact that the decorative surface material 29 is directly fixed to the wall surface 21 without the intermediary of a spacer 28 and that a trim material 82 is used, the construction structure of Figure 14C is formed in the same manner as the construction structure of Figure 10C.

[0065] (Variation 1) In the above description, the projected corner material 1 is formed from a solid member, but this is not limiting. The projected corner material 100 of Modification 1 shown in FIGS. 15A and 15B can be formed from a hollow member. In this case, the projected corner material 100 can be formed from, for example, metal or resin. The projected corner material 100 has a pair of front pieces 101. One end of each of the pair of front pieces 101 is connected to each other at a substantially right angle. Projected corner pieces 11 and 12 are provided at the other end of each of the pair of front pieces 101. The pair of projected corner pieces 11 and 12 each have side surfaces 111 and 121. The pair of side surfaces 111 and 121 are surfaces that face the end edges (end faces) 41 and 42 of the decorative surface material 4 applied to the two wall surfaces 21 and 22 when the projected corner material 100 is installed. The pair of projected corner pieces 11 and 12 also have inner surfaces 110 and 120, respectively. The pair of inner surfaces 110, 120 are surfaces that face the two intersecting wall surfaces 21, 22 of the wall base 2 when the corner member 100 is installed. The space surrounded by the pair of front pieces 101 and the pair of corner pieces 11, 12 forms a space 13, which communicates with the outside through an opening 130 formed between the pair of corner pieces 11, 12.

[0066] 15A, when no projection adjustment material is used, the projection corner portion 23 of the wall base 2 is inserted into the space 13 through the opening 130, and the projection corner material 100 is installed. When projection adjustment materials 31, 32 are used, as shown in FIG. 15B, the projection adjustment materials 31, 32 are provided between the inner surfaces 110, 120 and the wall surfaces 21, 22, and one end 310 of the projection adjustment material 31 is inserted into the space 13 through the opening 130. In this manner, the projection corner material 100 can be installed.

[0067] (Variation 2) The outside corner member 200 of modified example 2 shown in Figures 16A, 16B, and 16C is formed from a substantially solid member and can be formed from, for example, wood or resin. The outside corner member 200 has a substantially square cross-sectional shape when cut along an imaginary plane perpendicular to the longitudinal direction, and has a space 13 inside. The space 13 is a space with a substantially square cross-section, and is formed over the entire length of the outside corner member 200 in the longitudinal direction. The space 13 opens as an opening 130 at one corner of the outside corner member 200.

[0068] 16A, when no projection adjustment material is used, the projection corner portion 23 of the wall base 2 is inserted into the space 13 through the opening 130, and the projection corner material 200 is installed. At this time, the inner surface 110 of one projection corner piece 11 faces and contacts the wall surface 21. The inner surface 120 of the other projection corner piece 12 faces and contacts the wall surface 22.

[0069] 16B and 16C, a pair of projection adjustment members 31, 32 are used to construct a projection corner member 200. In this case, one projection adjustment member 31 is arranged between one wall surface 21 and one inner surface 110. The other projection adjustment member 32 is arranged between the other wall surface 22 and the other inner surface 120. In FIG. 16B, one end 310 of one projection adjustment member 31 is inserted into the space portion 13 from the opening 130. In FIG. 16C, one end 320 of the other projection adjustment member 32 is inserted into the space portion 13 from the opening 130. In this way, either one or the other of the pair of projection adjustment members 31, 32 can be inserted into the space portion 13.

[0070] (Variation 3) The outside corner member 300 of Modification 3 shown in Figures 17A and 17B comprises an outside corner body 301 and an auxiliary member 302. The outside corner body 301 is formed from a substantially solid member and can be formed from, for example, wood or resin. The outside corner member 300 has a substantially square cross-sectional shape when cut along an imaginary plane perpendicular to the longitudinal direction, and has a space 13 inside. The space 13 is a space with a substantially square cross-section, and is formed over the entire length of the outside corner member 300 in the longitudinal direction. The space 13 opens as an opening 130 at one corner of the outside corner member 300.

[0071] The auxiliary member 302 has an insertion portion 303 with a generally U-shaped cross section and attachment pieces 304, 305 protruding from both ends of the insertion portion 303. The auxiliary member 302 can be made of metal or resin. The pair of projection corner pieces 11, 12 of the projection corner member 300 include attachment pieces 304, 305. The insertion portion 303 is inserted into the space 13 of the projection corner body 301, and the attachment pieces 304, 305 protrude perpendicularly from the opening 130.

[0072] 17A, when a projection adjustment material is not used, the projection corner portion 23 of the wall base 2 is inserted into the insertion portion 303 and the space 13 through the opening 130, and the projection corner material 300 is installed. At this time, the inner surface 110 of one projection corner piece 11 (the inner surface of the mounting piece 304) faces and contacts the wall surface 21. The inner surface 120 of the other projection corner piece 12 (the inner surface of the mounting piece 305) faces and contacts the wall surface 22.

[0073] 17B, ​​a pair of projection adjustment members 31, 32 are used to construct a projection corner member 300. In this case, one projection adjustment member 31 is arranged between one wall surface 21 and one inner surface 110. The other projection adjustment member 32 is arranged between the other wall surface 22 and the other inner surface 120. One end 310 of one projection adjustment member 31 is inserted into the space 13 through the opening 130.
