As shown, the rock fracture barrier panel 100 according to the present invention has a rectangular plate shape, the screw groove 116a is formed on the front surface.

The screw groove 116a is made of a female screw 116 made of a metal material, and the surface thereof is formed to coincide with the panel for the rock fracture barrier 100.

The rock crushing barrier panel 100 is composed of a metal frame part (110 of FIG. 2) and an engineered plastic body part (120 of FIG. 2). The metal frame part 110 is exposed to the outside. It is not embedded in the body portion 120, the upper surface of the female screw 116 is exposed only around the screw groove (116a).

The rock shredding barrier is exposed to rain, snow and dust for a long time while exposed to the outside, and can only be used after having a crossover and a crossover over a wide temperature range. When using a metal material, there is a high risk of corrosion. Painting on the surface, but there is also a problem that the paint surface is easily damaged, there is a need to repeatedly remove the rust and painting work, the wood is vulnerable to moisture and there is a fear of corruption. In particular, when the water soaked in the winter and melted in winter, the strength of the wood was weak.

In order to improve the problems of the conventional material, the panel for rock fracture wall according to the present invention is made of an engineering plastic material, the inside of the frame portion 110 of the metal material serves as a skeleton to secure the strength It provides a structure.
