Double-curved-surface perforated aluminum plate structure

The utility model relates to a double-curved-surface perforated aluminum plate structure which is in a curved surface shape, is arranged below an outer eave of a building in an overhanging mode and comprises a plurality of supporting frameworks, a first aluminum plate component and a second aluminum plate component. The cross section of the first aluminum plate component is in a V shape, and the first aluminum plate component is laid at the upper end of the supporting framework in the length direction of the outer eave of the building so that a gradually-changed hyperboloid shape can be formed at the upper end of the supporting framework. The second aluminum plate component is laid at the lower middle end of the supporting framework in the length direction of the building outer eave so as to form a curved surface shape with a gradually-changed vertical face at the lower middle end of the supporting framework. According to the utility model, the plurality of second curved-surface aluminum plates are obliquely
