As shown in FIG. 4A, after the steel column 22 is erected, a lower runner 28 and an upper runner (not shown) are provided. A first angular stud 24 and a second angular stud 26 are erected with respect to a lower runner 28 and an upper runner (not shown).

On the other hand, as shown in FIG. 4B, the first fastening portion 37 is adhered to the Y direction outer end of the side surface 32B of the first finishing material 32 using double-sided tape 42 (see FIG. 3), A base metal fitting 36 is temporarily fixed to the first finishing material 32 . This tacking step is performed before the second finish 34 (see FIG. 2) is attached to the second square stud 26 (see FIG. 2).

Next, as shown in FIGS. 4C and 5A, the first finish 32 is attached in the X direction to the first corner stud 24 (side wall 24C) by tapping screws 29 (see FIG. 5A). The mounting positions in the Y direction of the first finishing material 32 and the base metal fitting 36 are determined by marking the floor in advance. As a result, the end surface 33, the side surface 38A, and the Y-direction outer side surface of the second angular stud 26 are flush with each other along the X direction. It is assumed that the inner finishing material 27 (see FIG. 5A) is attached to the first square stud 24 and the second square stud 26 in advance.

Next, as shown in FIGS. 4D and 5B, the second finishing material 34 is applied to the first finishing material 32 and the base fitting 36 (second fastening attachment) so that the side surface 32A and the end surface 35 are flush with each other. 38). In other words, the first finishing material 32 and the base metal fitting 36 are in a state of being abutted against the second finishing material 34 in the Y direction. In this state of contact, the second finish 34 is attached to the second square stud 26 by the self-tapping screw 29 in the Y direction.

Next, as shown in FIG. 5C, the second fastening portion 38 is fastened to the second finish 34 by the tapping screw 29 in the Y direction. Here, the position where the tapping screw 29 is screwed is a position separated in the X direction from the end surface 35 by a length equal to or longer than the thickness of the first finishing material 32 . Furthermore, the second finish 34 is in contact with the first finish 32 in the Y direction where the tapping screw 29 is screwed. In other words, the end surface 33 is abutted against the second finishing material 34 . Thus, when the tapping screw 29 is screwed into the X-direction outer end of the second fastening portion 38, the Y-direction displacement of the second finishing member 34 is restricted by the first finishing member 32. Therefore, deformation of the X-direction outer end of the second finishing member 34 can be suppressed.

Next, as shown in FIG. 5D, the first fastening portion 37 is fastened (mainly fastened) to the first finishing member 32 by a tapping screw 29 in the X direction. Here, the first finishing material 32 is in contact with the second finishing material 34 in the Y direction orthogonal to the X direction in which the tapping screw 29 is screwed. Therefore, when the tapping screw 29 is screwed into the Y-direction outer end of the first finishing member 32 in the X direction, the deformation of the first finishing member 32 in the Y direction is restricted by the second finishing member 34 . be done. As a result, deformation of the Y-direction outer end of the first finishing member 32 can be suppressed. The fastening position of the tapping screw 29 that fastens the first fastening portion 37 to the first finishing material 32 is the same as the fastening position of the tapping screw 29 that fastens the second fastening portion 38 to the second finishing material 34. is deviated in the Z direction with respect to Thus, the mounting structure 30, the external corner 20 and the wall 12 are constructed. Furthermore, wallpaper (not shown) is pasted on the outer sides of the first finishing material 32 and the second finishing material 34 .

As described above, in the mounting structure 30 , the first fastening portion 37 is fastened to the first finishing material 32 while the end face 33 of the first finishing material 32 abuts against the second finishing material 34 . The second fastening portion 38 is fastened to the second finishing material 34 . Also, a first finish 32 is attached to the first square stud 24 and a second finish 34 is attached to the second square stud 26 . Thereby, the wall 12 of the external corner 20 is formed.

Here, the first fastening portion 37 is spaced from the first square stud 24 and the second fastening portion 38 is spaced from the second square stud 26 . In other words, there is no base fitting 36 between the first finishing member 32 and the first square stud 24 and between the second finishing member 34 and the second square stud 26 . As a result, it is possible to prevent the thickness of the wall 12 of the external corner 20 from increasing by the thickness of the base metal fitting 36 .

Further, in the mounting structure 30, the absence of the base fitting 36 between the first finish 32 and the first square stud 24 and between the second finish 34 and the second square stud 26 allows the first finish 32, a second finish 34 is easily attached to the first 24 and second 26 corner studs; Thereby, the workability of the external corner portion 20 can be improved. In summary, in the mounting structure 30 , it is possible to prevent the thickness of the wall 12 of the external corner 20 from increasing and to improve the workability of the external corner 20 .

In addition, in the mounting structure 30 , the base fitting 36 is temporarily fixed to the first finishing material 32 by bonding the first fastening portion 37 to the first finishing material 32 with the double-sided tape 42 . Therefore, when the first finishing material 32 and the second finishing material 34 come into contact with each other before the base metal fitting 36 is permanently fastened to the first finishing material 32, a pressing force acts on the base metal fitting 36. Even if it happens, the base metal fitting 36 held by the adhesive force of the double-sided tape 42 resists this pressing force. As a result, misalignment of the base metal fitting 36 is suppressed.

Here, the first finishing material 32 is in contact with the second finishing material 34 when the base fitting 36 is fastened to the first finishing material 32 . Therefore, even if a force that causes deformation is applied to the end of the first finishing material 32 by the fastening operation of the base metal fitting 36, the expansion of this deformation is restricted by the second finishing material 34. be. As a result, deformation of the end portion of the first finishing material 32 can be suppressed when the base metal fitting 36 is fastened to the first finishing material 32 .

Next, in the mounting method of the wall material 31 , the first fastening portion 37 of the base metal fitting 36 is fastened to the first finishing material 32 . A first finish 32 is attached to the first square stud 24 remote from the furring 36 . A second finish 34 is attached to a second square stud 26 spaced apart from a furring 36 in spaced relation to the steel column 22 in the Y direction and in contact with the first finish 32 . Then, the second fastening portion 38 is fastened to the second finishing material 34 . Thereby, the wall 12 of the external corner 20 is formed.

Here, the first fastening portion 37 is spaced from the first square stud 24 and the second fastening portion 38 is spaced from the second square stud 26 . In other words, there is no base fitting 36 between the first finishing member 32 and the first square stud 24 and between the second finishing member 34 and the second square stud 26 . As a result, it is possible to suppress the thickness of the wall 12 of the external corner 20 from increasing.

Furthermore, in the mounting method of the wall member 31 , there is no base fitting 36 between the first finishing member 32 and the first square stud 24 and between the second finishing member 34 and the second square stud 26 . Therefore, since the first finishing material 32 and the second finishing material 34 can be easily attached to the first square stud 24 and the second square stud 26, the workability of the external corner portion 20 can be improved. In summary, in the mounting method of the wall material 31, it is possible to prevent the thickness of the wall body 12 of the external corner 20 from increasing and to improve the workability of the external corner 20.

In addition, in the mounting method of the wall member 31, the first fastening portion 37 is temporarily fixed to the first finishing member 32 by adhesion. As a result, when the first finishing member 32 and the second finishing member 34 come into contact with each other before fastening the base metal fitting 36, the position of the base metal fitting 36 is prevented from being shifted.

Here, when the base metal fitting 36 is fastened (mainly fastened) to the first finishing material 32 , the base metal fitting 36 is already fastened to the second finishing material 34 . Furthermore, the first finishing material 32 is in contact with (butting against) the second finishing material 34 . As a result, when the base metal fitting 36 is fastened to the first finishing material 32, the fastening operation of the base metal fitting 36 may exert a force that deforms the end portion of the first finishing material 32. Also, the expansion of this deformation is restricted by the second finishing material 34 . As a result, deformation of the end portion of the first finishing material 32 can be suppressed when the base metal fitting 36 is fastened to the first finishing material 32 .
