In addition, the composite material bottom plate 140 of the present invention may be configured by forming a non-slip coating film 150 on the upper surface of the bottom plate. At this time, the anti-slip coating film 150 may be formed of a silica sand coating.

Therefore, the composite material base plate 140 of the present invention has a superior moisture absorption rate compared to a conventional wooden floor plate, and thus has no member deformation and can significantly improve performance such as durability. In addition, it is possible to improve walking stability by securing sliding resistance in all directions by applying a silica coating film to the bottom plate. In addition, since it is composed of a glass fiber composite material, it can be used semi-permanently, and it can significantly reduce maintenance costs because it can extend the floor plate replacement cycle 5 to 10 times longer than conventional wood floor plates.
