PURPOSE: A prefabricated construction metal panel is provided to minimize the inflow of rainwater caused by wind pressure by forming two constant pressure spaces with a groove and a protrusion. CONSTITUTION: A prefabricated construction metal penal includes first and second protrusions (51,52) on the upper surface and includes first and second grooves (53,54) on the lower surface. The first groove is comprised by bending a front plate (10), and the second groove is comprised by bending a rear plate (20). When the metal penal is vertically laminated, the first protrusion is attached to the upper surface of the first groove so that a first constant pressure space (71) is formed. A second constant space (72) is formed in a connection part of the first protrusion and the first groove and in a connection part of the second protrusion and the second groove. |
