Each of the inner wall frames 2a and 2b is made of wood or metal, and each of the inner wall boards 4a and 4b is made of gypsum. However, other materials may be used. The splint 3 is used to secure the right angle of the protruding corner, but the protruding corner may be formed only by the inner wall frames 2a and 2b without using the splint 3. .

As shown in FIG. 3, the joint member 5 is a plate-like body bent so as to have a shape extending to a side intersecting two adjacent sides of a regular square prism. The length a of the side coincides with the vertical dimension of each inner wall board to be attached to the protruding corner. On the other hand, the lengths b1 and b2 are equal to the thickness of each inner wall board to be attached to the protruding corner. Usually, since the inner wall boards having the same thickness are used, the length b1 and the length b
2, and the joint member 5 has a shape similar to a square prism. However, when the thickness of each of the inner wall boards used at the protruding corners is different, the lengths b1 and b2 are respectively set to the inner wall to be in contact with each other. Match the board thickness. Therefore, in such a case, the joint member does not have a shape similar to a square prism.

The lengths b3 and b4 may be any lengths as long as they are long enough to determine the position of the joint member 5 at the protruding corner by contacting the splint 3. Considering the convenience and the like of the attaching work, it is desirable that the length is approximately the same as the lengths b1 and b2.

The thickness of the plate member of the joint member 5 varies depending on the material used and the structural strength required for the protruding corner. Examples of the material of the joint member 5 include metal such as steel, reinforced plastic, and carbon.
When the joint member 5 has a certain thickness,
As shown in FIG. 2, a gap corresponding to the thickness of the joint member 5 is generated between each of the inner wall frames 2a and 2b and each of the inner wall boards 4a and 4b. In order to eliminate the gap, as shown in FIG. 4, a taper is provided at the joining edge on the protruding corner side of the inner wall board in contact with the joint member 5. The taper to be provided is set in consideration of the lengths b3 and b4. When the thickness of the joint member 5 is small, for example, when a thin iron plate of about 0.4 mm to 0.5 mm is used, the taper need not be provided.

Further, according to the lengths b3 and b4, FIG.
As shown in FIG.
1 is provided. FIG. 6 shows a part of the cross section taken along the line AA in FIG. 4. As shown in FIG. 6, the nail 6 driven to attach the inner wall board 4 a to the splint 3 is
