In the conventional protective shelf configured as described above, the safety net 8 installed in the square frame formed by the frame 5 and the upper and lower short pipes 6 and 4 installed on both sides is provided by a separate fixing device. Safety net (8) because it can be easily fastened using the binding ring (5a) or the binding ring (6a) (4a) provided in the frame (5) and the upper and lower tube pipe (6) (4) There is an advantage that can be easily performed assembly.

However, the support brackets 2 and 3 are fixed to the balcony jaw 1 by a hanger, respectively, and because the materials of the support brackets 2 and 3 are all made of metal, they are fixed with the balcony jaw 1, which is a concrete casting. A problem arises in that the coupling sensitivity is not so high.

The object of the present invention for solving the above problems, and relates to the fall prevention network fixed structure, in particular, safety accidents due to falling objects falling to the outside of the building when the construction of the building in the construction site, such as bridges or bridges When installing the safety net to prevent the fall prevention net fixing anchor to install a firmer and safer fall prevention net by increasing the coefficient of friction when the fixing member anchor installed on the outer wall of the building is fixed to the building. To provide.

A feature of the anchoring device for anchoring the drop prevention net according to the present invention for achieving the above object, as having a bent portion of the structure of the upper and lower portions of the main body having a 'c' shape as a whole, and the internal space of the main body A drop preventing net fixing anchor having a crimping portion positioned and sliding along a long hole formed on one side of the main body, and a bolt for pressing the crimping portion in one direction: A first rubber pad formed on a lower surface of the crimping portion. Wow; Any of the bent portions of the main body positioned between the first rubber pad and the second rubber pad by the pressing force of the bolt as the second rubber pad covers the bent portion of the main body facing the lower surface of the crimp portion. It is settled and fixed with high coefficient of friction in the structure.

As expected effects due to the above-described features of the present invention, since the rubber pad covers the tooth structure, any structure sandwiched between the tooth structure is primarily protected by the rubber pad. At the same time, it can be prevented from slipping or being unfixed during the process of being tightly fixed by the compression structure between different materials between the conventional metal structure and the concrete structure due to being fixed with high friction coefficient. It became.
