Description

The present invention relates to a cylindrical body fixing jig that prevents a cylindrical body such as a pipe or a round bar from rolling and can also be used as an auxiliary tool for tightening a connecting portion of the cylindrical body.

Pipes such as steel pipes, stainless steel pipes and polyethylene pipes, and cylindrical bodies such as round bars are used in various situations such as being used for supplying gas and water in buildings and being used as scaffolding. Therefore, there are many situations where cylindrical materials are placed in material storage areas at construction sites. Since a plurality of cylindrical materials are usually stacked and placed, it has been pointed out that there is a risk of accidents due to collapsing or rolling at a construction site.

Therefore, a technique for preventing pipes such as pipes and pipes from rolling has been proposed. For example, Patent Document 1 describes a rolling prevention device for columnar objects placed in a row, which is suitable for use when columnar objects (long circular cross-section members) such as logs and columns are arranged in a row and further stacked. Describes techniques for rolling prevention methods.
