Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a safety fence on the roof of a unit house, and can be used when assembling a housing unit. After manufacturing the roof as a living room unit and the roof unit as a roof unit having a roof main unit and an eaves unit, these housing units are transported to a construction site, and each housing unit is lifted and assembled using a crane or the like. Increasingly, prefabricated unit houses are being constructed.

When assembling such housing units, workers perform work such as sealing between roof units while riding on scaffolding or roof units formed on the eaves unit.

[Problem to be solved by the invention 1 Conventionally, work such as sealing between roof units was carried out on narrow scaffolding formed on the eaves unit or on sloping roof units, which created a risk of workers accidentally falling. there were. Although it is possible to work with a lifeline attached, the disadvantage is that it is difficult to work.

Therefore, in Utility Application No. 1-107945, the present applicant utilized a fastener for lifting the eaves unit, installed a handrail with a fastener to be fastened to the fastener at the lower end,
We proposed a scaffolding structure for construction of unit housing that uses handrails to ensure the safety of workers.

In this type of handrail, the threaded part of the support is screwed into a nut for lifting the eaves unit, and one pipe is fixed at the top and bottom between the supports, so there is no chance of a worker falling into the pipe. There was a risk that the pipes and pillars would bend due to the impact caused by the impact.

Additionally, because the spacing between the installed supports was wide, long pipes were used or multiple short pipes were connected on site.

However, long pipes are inconvenient to transport, and the work of connecting the pipes is troublesome.

SUMMARY OF THE INVENTION An object of the present invention is to provide a safety fence for the roof of a unit house, which is free from the risk of safety members and supports being bent by impact and is easy to install.
