The present invention relates to a method and an apparatus for constructing a wall. The apparatus for constructing a wall comprises: Euroform frames consisting of Euroform panels which are arranged facing each other and are continuously mounted in a horizontal direction; Euroform connecters which are mounted on the Euroform panels and on connection parts of the Euroform panels in a vertical direction at intervals; and panel supporters, one side of which is coupled to the outer surface of the Euroform panels, and the opposite side of which is supported by the ground. According to an embodimentof the present invention, when constructing a wall, it is possible to conveniently configure Euroform frames without ties and fastening pins, thereby having effects of reducing labor costs and minimizing the number of components, and it is possible to exclude removing and plastering works of ties and fastening pins, thereby having an effect of reducing work time and construction costs.
