2. Description of the Related Art Conventionally, when constructing a building or constructing an outer wall, scaffolds are temporarily installed around the building using logs, iron pipes, etc. to support the passages of workers and members in the frame. It is used for tensioning the fall prevention sheet. When temporarily constructing such a scaffold, a retaining material called a "wall joint" is erected at regular intervals between the scaffold and the building in order to prevent and stabilize the scaffold. The installation of wall sills is also stipulated in the Industrial Safety Standards Act from the viewpoint of ensuring safety during work. As a wall tie, it is generally known that a rod-shaped member is simply fixed to both a scaffold and a building by using a wire or a fixing metal fitting.

[0003]

The wall tie as described above was removed at the same time as the scaffolding was removed as the construction was completed. When the outer wall is a wet method such as mortar finishing, the mark left after removing the wall joint may be repaired with mortar or the like, and the repair work is relatively easy and does not deteriorate the appearance. However, in recent years, a dry method using an outer wall material such as a siding material has come to be widely used, and after removing the wall joint, it is necessary to repair the hole for mounting the wall joint provided in the outer wall material. There was a problem that not only the repair work was time-consuming, but also the repair traces became conspicuous. Further, there is a problem that the outer wall material may be damaged when the wall joint is removed.

[0004] Further, as a wall joint attachment for fixing the wall joint to the structural body, there is disclosed in JP-A-4-363467 or JP-A-4-363467.

However, according to the wall tie fixture 10 described in Japanese Patent Laid-Open No. 4-363467, the wall tie fixture 10 is screwed into the outer wall material 30 itself, so that not only when the scaffold is removed, but also during temporary construction of the scaffold. However, there is a problem that the outer wall member 30 may be damaged, and it takes a lot of time to repair the through hole 310 after removal, and the repair trace is conspicuous.

According to the wall joint attachment 10 'described in Japanese Patent Laid-Open No. 6-57943, it takes time and labor to pre-drill the hole 410', and the wall joint attachment 10 'is embedded in the hole 410'. There is a problem in that the outer wall material may be damaged when the wall joint fixture 10 'is removed. Also,
Not only is it difficult to repair the through hole of the outer wall material after removal, but there are also problems that the repair marks are conspicuous.If you leave it without removing it, you cannot adjust the protrusion amount, and you can adjust it so that it is flush with the surface of the outer wall material. There is also the problem that it cannot be done.

Therefore, an object of the present invention is to be able to reliably install a wall joint, to prevent the appearance of the scaffold from being deteriorated even after the scaffold is removed, and to use it again when repairing the outer wall in a later year.
