Description

    The present invention relates to a fall-preventing safety fence composed of a storage-type ladder-supported column, a protection net, a holder, and the like that are temporarily installed when a solar power generation panel is installed.

    Conventionally, not only for solar power panel installation work, but also when working on high places related to construction, pipe materials that serve as work scaffolds are combined on the side wall surface of the house, and a net or sheet is stretched around the outer peripheral surface and dropped. Safety measures such as prevention, noise / dust prevention and scattering prevention are taken.

    However, in the case of solar power panel installation work, except for the case of new construction work, most of the additional work is done on the roof of the existing house. That was a problem in terms of construction period, cost and workability.

    Therefore, it is possible to develop and provide a fall prevention safety fence for solar power generation panel installation work that anyone can somehow easily assemble and disassemble in a short time, and the structure is simple, inexpensive and safe to work with. It is desired.

Then, the patent document regarding the fall prevention safety fence filed so far is introduced for reference (see Patent Documents 1 to 3).
