The present invention relates to a safety net installation frame that can prevent safety accidents and facilitate storage and transportation, as well as reduce production costs by a simple configuration.

In general, in the case of new / extended construction of a building structure such as a factory or an apartment, a frame work for constructing a skeleton of the building structure by using a steel frame (beam) should be preceded.

In constructing such a steel structure, the steel frame itself is formed in a lattice-like structure inside the construction structure, so it is possible to easily install a separate strut, etc. based on this, if necessary, using such a frame and temporary materials Therefore, it is possible to easily install a horizontal safety net to prepare for safety accidents such as falling of building materials and remnants that occur in the interior of the construction building and falling of the worker.

In contrast, due to the difficulty of installation due to the lack of proper infrastructure, a considerable amount of time and effort must be devoted to the exterior of the building structure, thus reducing the work efficiency or without installing the safety net. There are many cases where there is a risk of falling of building materials residues or falling of workers to the outside of the building.

This fall hazard is the same as the case of performing roof finishing work as well as the frame work as described above.
