Abstract:
PURPOSE: To aim at the safety of workers by stretching main ropes between two poles respectively supported by a pole fixing device, and connecting the main ropes at appropriate positions in the ridge direction and in the gable direction, and connecting a protecting net to these main ropes.
CONSTITUTION: Poles 3 are loosely fitted in pole supporting members 13, 14 of a pole fixing device by a pipe material. A lock pin is fixed to the lower end of the pole supporting members 13, 14 in the radial direction, and the lower end of a small diameter part of the pole is formed with an axial directional notch at a predetermined length, in which the locking pin is loosely fitted. The upper end of this notch is formed with a circumferential directional notch at a predetermined length, in which the locking pin is loosely fitted. After the axial directional notch of the small diameter part of the pole is engaged with the lock pin provided in the lower end of the pole supporting members 13, 14, the small diameter part of the pole is twisted for locking in relation to both the pole supporting members. Two main rope stretch parts 3e are fixed to the upper end of the pole in the radial direction and the right-angle direction to connect a protecting net 6 to the main ropes 4 stretched in multiple directions. Safety of workers 5 on the roof is thereby secured.
