た。2. Description of the Related Art Conventionally, work such as installation of a TV antenna and installation of a solar water heater has been performed on a roof. At the time of such work, equipment and facilities for fall and fall prevention were rarely provided, and accidents were frequently seen. The reason for this is that, even when working on high altitudes, ordinary work on the roof is a short-time work at a relatively low position, so the tiles laid on the feet do not directly see the ground. One of the causes was that the equipment was not installed.

の場合には適用できないという問題もあった。Under the circumstances described above, as a partial measure, columns and fixing brackets are installed at both ends of the building, and a horizontal rope is installed between them to secure the safety belt. A method of locking a hook may be employed. However, this method takes a long time to install, and sometimes takes more time than the original working time. In addition, there is a problem that the owner of the building may not understand the mounting of the support itself, and there is a problem that the method cannot be applied to a case where the roof shape is a building near the building.

滑落時の距離を小さくすることができる。At this time, the loop-shaped portion 11 is narrowed so that the position of the tensioning tool 13 provided on the main rope support rope 1 is near the ridge on the surface of the roof 41 to be worked.
When this work is completed at both gable ends 42 and 43 of the roof,
The main rope 2 is stretched between the parent ropes 1a and 1b. Parent rope 2
Is hooked on the connecting ring 14 of the tensioning tool 13 of the one main rope support rope 1a, and the rope 22 is extended along the ridge. On the other hand, the tensioning tool 2 located at the other end of the rope 22
The third hook 24 is hooked on the connecting ring 14 of the tensioning tool 13 of the main rope support rope 1b. Next, the length is adjusted using the tensioning tool 23 of the master rope 2, and the tension is increased as much as possible. By doing so, it is possible to prevent the loop-shaped portion 11 of the main rope support rope 1 from coming off from both end portions 42 and 43 of the gable, and to reduce the distance of the worker when sliding down.
