[0002]
[Prior art]
Conventionally, a system scaffold as a work stage is sometimes used when various construction work such as interior decoration, painting, or electrical work is required for a high position such as an upper part of a wall or an indoor ceiling. As this system scaffold, for example, those described in Japanese Patent No. 2996385 and Japanese Patent No. 2997427 are known.
These known system scaffolds are composed of a plurality of scaffolds individually supported by supporting the top board with a plurality of support legs, and the top boards of the respective scaffolds in a state where these scaffolds are installed close to each other. It has a scaffolding connection board constructed between them.
[0003]
And as a structure for connecting the top plate of each scaffold and the scaffold connecting plate, a hook and a support shaft are provided on the scaffold connecting plate side, and a hook receiving frame and a shaft support hole are formed on the scaffold top plate side in a manner corresponding to these. It was the structure which provides.

It was necessary to provide a connecting structure such as.
However, the scaffold connecting plate and the scaffold are not necessarily sold and distributed as an inseparable set, and may be purchased according to various circumstances on the side of the contractor such as breakage or expansion.
[0005]
For this reason, for example, the connecting structure provided on the already-owned scaffold (or scaffolding connecting plate) and the connecting structure provided on the scaffolding connecting plate (or scaffolding) to be purchased are classified into the manufacturer, model number, etc. Needs to be addressed.
Therefore, it is very troublesome with respect to such a purchase, and in some cases, a corresponding product may not be found due to a difference in model year (because it is an abolished number). The same was true for the ladder used for this system scaffold.
[0006]
On the other hand, in a conventionally known system scaffold, when the scaffold and the scaffold coupling plate are coupled, when the hook and the hook receiving frame are engaged, or when the support shaft and the shaft support hole are engaged, they are engaged. The relationship is unambiguous, and there is almost no degree of freedom in the horizontal direction and the vertical direction.
For this reason, there are cases in which assembly as a system scaffolding cannot be performed at a site where there is a step or an inclination on the floor, or a site where the scaffold and the scaffold connecting plate cannot be connected in a straight line due to space. This was also true for the ladder described above.
