Abstract: The present disclosure provides a corrugated concrete wall panel form and a method of constructing a prefabricated concrete wall panel thereof. The method comprises the steps of placing a layer of insulation boards horizontally on a flat surface on site or in pre-cast plant; laying and attaching one layer of corrugated metal thin sheets, as the bottom concrete form, on top of the horizontally placed insulation boards; closing the sides of the corrugated metal sheets by peripheral angles as side forms; and then pouring concrete on top of the metal sheets. After concrete hardens the wall structure is ready for erection. This low cost lightweight wall panel system is self-containing and requires only one pour of concrete. It requires no complicated form structure and less labor work for form installation.
