By the way, when repairing such a panel wall, a scaffold is temporarily installed along the panel wall, but in view of strength, a scaffold joint for preventing the collapse of the scaffold is directly attached to the stone 5. I can't take it. For this reason, conventionally,
When the height of the joint 8 between the upholstery stones 5 is larger than the bolt diameter, the bolt is embedded in the concrete skeleton 1 and the joint 8 is inserted to extend the tip of the bolt protruding from the upholstery stone 5. The scaffold joint is directly connected to the skeleton 1 by screwing a screw-in bolt for connecting the scaffold via a nut. On the other hand, when the joint 8 is too narrow to allow the bolt to be inserted, a hole is made in the paving stone 5 at the scaffold connecting position, and then the bolt is inserted into the hole to connect the scaffold. After removing, the hole formed in the upholstery stone 5 was repaired by a filling stone or the like.

[0004]

However, in the above-mentioned conventional scaffolding connection structure, when the scaffold is temporarily installed,
There is a problem that the bolt must be driven into the concrete skeleton 1 again as an anchor, and when a hole for inserting the bolt in the stone 5 is to be drilled, additional work for repairing the hole increases. In addition, there is a problem in that the appearance of the panel wall may be impaired.

The present invention has been made to effectively solve the problems that occur when connecting scaffolds in the conventional panel wall as described above. It is not necessary to embed a new anchor, and it is easy to do without damaging the panel. An object of the present invention is to provide a scaffolding fitting for a panel wall, which can be connected to a scaffolding connection.
