According to an embodiment of the present invention, a prefabricated panel comprises: a first panel unit; a second panel unit; and a reinforcing unit placed in between the first panel unit and the second panel unit. The first panel unit comprises: a flat panel unit having a certain area; and a bending unit formed by bending from one end in the lengthwise direction of the flat panel unit. The bending unit comprises: a reinforcing unit bent and extended from one end in the lengthwise direction of the flat panel unit in a first direction in order for a reinforcing space to be formed between the flat panel unit and the bending unit providing a side facing the flat panel unit; and a binding unit bent and extended from the end of the reinforcing unit to a second direction in order for a binding space to be formed between the reinforcing unit and the binding unit providing a side facing the reinforcing unit. The first direction is the opposite direction to the second direction, and the binding space provides a space where the other end of the flat panel unit connected to one end in the lengthwise direction of the flat panel unit is inserted into. The reinforcing unit and the binding unit giving pressure respectively to one side and the other side of the flat panel unit connected with one end in the lengthwise direction of the flat panel unit. |
