2. Description of the Related Art A silo is a facility for storing raw materials or products. The silo has an inlet and a sampling port, and can be sealed and fumigated for insect control, and has a structure for preventing dew condensation. Have. Inside the silo, powders and vapors rising from the stored matter adhere to the upper wall, especially the ceiling, and thus need to be cleaned frequently. Scaffolding must be obtained for the cleaning work, but conventionally, a method has been adopted in which the inside of the silo is filled with storage and covered with a sheet or the like to form a work place. However, there are restrictions on the amount of storage and storage time, and some cannot be filled. When the silo is full, the risk of fire and dust explosion increases.

On the other hand, Japanese Utility Model Application Laid-Open No. 51-59136 proposes a device for providing a scaffold inside a silo or the like.
The device has a radial scaffolding member that can be raised and lowered along a true bar located at the center of the silo. Thus, a scaffold is provided without filling the store, but the storage capacity is reduced by the scaffolding device. On the other hand, JP-A-6-22911
No. 5 is considered to be easily installed and removed because it is inserted into the tank from the canopy manhole, but it is not possible to clean the inside of the canopy, that is, the ceiling, because of the wire that suspends and supports the scaffold on the center column. It will be near or at least impeded. In addition, it is considered that the problem of shaking occurs due to the configuration of being suspended at the center.
