Description

Safety railing

The present invention relates to a safety guardrail, and more particularly, to a safety guardrail which is fixedly mounted on a steel beam forming a foundation frame of a building, and can be installed with safety facilities.

In general, when a building is to be expanded or repaired, a temporary fixing unit (safety bracket or the like) is installed at the periphery thereof, and then a pedestal or the like is installed using a temporary fixing unit or a safety net is installed to secure the working space, And a work space.

The temporary fixing unit installed in this way allows the rope to be horizontally bundled or welded to the railway beams or other separately provided railing supports to prevent the operator from falling down or to maintain a safe working condition .

However, in the related art, since the temporary fixing unit is fixedly installed through a special welding process or a complicated joining process to a steel beam, it takes a lot of time and labor to install the temporary fixing unit and a considerable effort is required to separate the temporary fixing unit .

Therefore, there are many fixed units that can be installed more easily and stably, and at the same time, can be easily disassembled and reused. However, the conventional structure can not be fixed firmly. That is, there is a problem that the area fixed to the steel beam is small and the fixing in a relatively solid state can not be obtained.
