Further, a flange tightening bolt of the steel frame beam is screwed into an upper horizontal part of the groove member for attachment to the flange of the steel frame beam to which the coiled hook for attaching the horizontal safety net in the jig for suspending the safety net is attached. Since the bolt is tightened and loosened, the jig of the present invention can be easily attached to and detached from the steel beam. Further, since the coiled hook is composed of an upward hook for hanging the horizontal safety net and a downward hook for preventing the safety net from coming off, the horizontal safety net can be easily attached,
After installation, the horizontal safety net can be easily removed at the same time without slipping off, and since the coiled hook is attached to the outer surface of the vertical member of the channel member, the upper flange portion of the beam steel frame is attached. For the worker who mounts the horizontal safety net by riding on the rail, the hook is located closer and easier to see as compared with the case where the hook is mounted on the lower surface of the horizontal member of the groove-shaped member. The net can be easily installed and the safety during installation work is improved. Furthermore, since the jig and the safety net according to the present invention can be used again, the cost can be reduced.
