[0002]

2. Description of the Related Art Conventionally, as shown in FIGS. 25 and 26, a method of attaching a rectangular wall plate material to a wall surface is through a through hole 50.
A through hole 60 is bored in the thickness direction using a mounting member 58 in which a horizontal portion 56 having a through hole 54 is arranged in parallel at a suitable interval in the horizontal portion 52 having a hole. 6
The wall plate member 64 having the lateral hole 62 for the positioning pin perforated orthogonally to 0 was sequentially attached to the wall surface 66.

The procedure is as follows. First, the mounting bolt 70 is embedded in the through hole 60 of the wall plate member 64, and then the wall plate member 64.
In front of the mounting bracket 58, the mounting bolt 70 embedded in the wall plate 64 and the through hole 5 in the other horizontal portion 56 of the mounting bracket 58.
4 are aligned with each other, and the through hole 54 of the horizontal portion 56 is positioned.
The mounting bolt 70 is inserted into the mounting through the nut 74
After fixing to the metal fitting 58, the anchor bolt 68 is inserted into the through hole 50 of the one horizontal portion 52 of the mounting metal fitting 58 to fix the mounting metal fitting 58 to the wall surface 66, and then to the positioning pin lateral hole 62 of the wall plate material 64. The positioning pin 72 is attached.

Next, a mounting member 58 to which another wall plate member 64 is fixed by the above procedure is positioned above the wall plate member 64, and then this mounting member 58 is fixed to the wall surface 66, and at the same time, the wall plate member 64 is fixed. The pin 72 attached to the fixed wall plate member 64 is attached to the horizontal hole 62 of the.

[0006]

In the conventional method for mounting a wall plate material on a wall surface, when the through hole and the lateral hole are bored in the wall plate material, the positions of the through hole and the lateral hole of the wall plate material are orthogonal to each other. It is necessary to move the wall plate material in the vertical and horizontal directions to make both holes, and when using a stone plate for the wall plate material, it has been a problem that it is difficult to process both holes in the wall plate material.

In addition, when the wall plate material is attached to the wall surface in a grid pattern, since the wall plate material can be mounted only in each row, it is difficult to align the other adjacent rows, and thus the grid rows are likely to be misaligned. That was a problem.

When forming joints between the wall plate members to be attached to the wall surface, the wall faces are marked in advance corresponding to the dimensions of the wall plate members and the widths of the joints, and the wall plate members are sequentially attached in correspondence with the marks. Since it is necessary to fix it with metal fittings, this work is very complicated and has been a problem.

In view of such drawbacks, the present invention is a method for attaching a wall plate material to a wall surface, which facilitates the work of forming the support groove and the support hole of the wall plate material and the work of attaching the wall plate material to the wall surface. Another object of the present invention is to provide a fitting for a wall plate material.
