More particularly, the present invention relates to a fiber-reinforced concrete structural steel sheet and a method of manufacturing the same, The present invention relates to a structural fiber steel sheet which can be shortened in size and which can improve the functions of waterproof, cold weather, heat insulation, moisture proof and soundproofing by constructing the inner wall surface, ceiling and floor of the room, .
The interior and exterior materials of the building are required to be lightweight while requiring a horizontal drag (bending strength) and a vertical drag (compressive strength) to withstand the mechanical properties, especially the force applied in the horizontal direction. In addition, flame retardancy is a very important factor that must be considered from the design stage, and much efforts have been made to develop an interior and exterior material having excellent flame retardancy. However, it has been found that only one or several of horizontal drag, lightweight, It is impossible to select interior and exterior materials.
Therefore, there is still a demand for developing an interior and exterior material satisfying all of the above conditions, that is, flame retardancy, light weight, high horizontal drag, and the like. In addition to the above-mentioned conditions, economical aspects and possibility of mass production should be considered.

Especially, they are weak to high temperature and low temperature due to water, When locked, general MDF, wood, plywood and the like have a problem that the initial original shape is deformed or disturbed because its volume is blown.
For example, a flame-retardant material containing 40 to 300 kg / m 3 of a density of 40 to 300 kg / m 3 on a polyester non-woven fabric is coated on the flame retardant insulating panel of Korea Registered Utility Model No. 20-0279956, It is said that it becomes a heat-insulating panel having excellent flame retardancy when it is used as a panel for interior materials by heating and drying.
However, this method has a problem in that the cost is low due to the addition of a process in the process of producing a flame retardant by stirring the silicone with a solvent and a delay in the process time, and there is a problem in that it is difficult to obtain a high density polyester nonwoven fabric having a density of 40 to 300 kg / There is a problem in that when the flame-retardant treatment is performed, the market competitiveness is lost due to an increase in the cost burden due to limitations and high density of architectural interior and exterior materials which are required to be lightened due to an increase in self- Since the panel is made of a multilayered plate structure by arrangement, if the panel itself is made of the method disclosed in the above-mentioned 'flame-retardant insulating panel', the horizontal drag and the vertical drag are weak.
