摘要： A wind turbine tower wall having an orifice for accessing the interior of the tower, and an outer surface defined by generatrices; and a reinforcement frame joined to the tower in the orifice zone, and comprising least two parts joined one to each other. Each part has a mid-plane that is parallel to at least one generatrix, the mid-planes of at least one pair of adjacent parts forming an angle other than 180° therebetween. It enables the obtention of a frame more conformed to the curvature of the tower, combining savings in the material of said frame, greater optimization of the resistance of the tower and reduced stress concentration.
