上において楽な姿勢で行うことができ、作業の安全性に
優れるものである。Further, the connection between the wire lattice net units can be achieved only by inserting the tubular body-like insertion portion into the tubular portion having the opening in the connecting member, and does not require welding as in the prior art. Therefore, the installation of the net is simplified and can be performed quickly. Further, even when the line lattice net unit is partially replaced due to damage or the like, it can be easily performed. Also, since the attachment of the net to the wall or the like is performed via the bracket member and the hanging member, the operation of removing the net, partially replacing it, performing maintenance, etc. is easy on the ground with the entire net in a vertical state. It can be performed in a posture, and is excellent in work safety.
