The present invention relates to a clamp for supporting a drop preventing net, and more particularly, to a clamp for supporting a drop preventing net coupled to a foam hole formed in an outer wall of a building, and a method for installing a drop preventing net using the clamp and a structure thereof.

In the construction of the building, it is necessary to use various objects including work tools, and the work is often performed at a high place, and falling objects may occur. In addition, the accident that the worker falls frequently occurs because people often perform their own work. Statistically, 8.0% of the deaths occurred in the construction industry were caused by falling objects, and 57.4%, which was about seven times higher, were caused by workers' inadvertent fallouts (Korea Occupational Safety & Health Agency, 2004) 612 precision analysis results).

For this reason, Rule 456 of the Industrial Safety Standards prescribes the installation and method of the fall prevention net to prevent the risk of falling objects among various hazards. It should be inclined by maintaining the angle of 20 ~ 30 degrees, and the installation height should be 10m. It should be observed in all construction sites.

Various fall prevention networks and installation structures have been proposed to prevent falling objects and to mitigate the impact of a worker's fall in order to meet the problems of the construction site and the regulations thereof.

With reference to the drawings briefly looks at the configuration of the conventional drop prevention net.

Referring to Figure 1 it can be seen that the configuration of the prior art 1, that is, a structure in which the fall prevention net is installed in the scaffolding pipe woven into the outside of the building.

A rectangular frame is formed by using a pipe, the safety net 22 is installed inside the frame, and then the strength of the safety net 22 is reinforced with a reinforcing tape 23, and the lower end of the frame is a lateral scaffold. While fixing directly to the pipe, the end is held by the upper end of the frame by using a wire (or pipe) 10 fixed to the scaffolding pipe at a predetermined interval from the scaffolding pipe on which the bottom of the frame is fixed. The frame is configured to be installed at an inclined angle.

However, the above configuration has a problem in that it is not applicable where the scaffolding pipe is not required since the scaffolding pipe is installed and then the drop prevention net is installed. There was a problem in that there was no configuration between the building and the scaffolding pipe to prevent any fall prevention means. In other words, the falling objects falling into the space between the building and the scaffolding pipe had a fatal problem that can be left to fall or prevent the fall by installing a separate structure.

* Moreover, in order to install the fall prevention network as described above, the worker had to carry out all the work while riding on the scaffolding pipe, and thus the risk of having to work in a fairly dangerous environment caused many problems.
