摘要

Reinforced polygonal drum of nested corrugated sheet material comprising: - an external tubular prismatic body (11) with an even number of sides greater than four, formed by a first band of corrugated sheet material with transverse folds parallel to each other defining said sides of the external tubular prismatic body forming a closed envelope; - an internal tubular prismatic body (12) with a number of sides equal to the number of sides of the external tubular prismatic body (11), the inner tubular prismatic body (12) being formed by a second band of corrugated sheet material with parallel transverse folds together they define said sides of the internal tubular prismatic body (12) forming a closed envelope; - a base body (20) defined by a panel of corrugated sheet material cut and folded defining a polygonal bottom (21) and a polygonal base wall (22) surrounding said polygonal bottom (21) and perpendicular thereto, both with equal number of sides that the external tubular prismatic body (11) and of complementary size with one end of the external tubular prismatic body (11); wherein the internal tubular prismatic body (12) is inserted into the external tubular prismatic body (11), the extrados being on each side of the internal tubular prismatic body (12) attached to the intrados of one of the sides of the external tubular prismatic body (11), forming a polygonal tubular body (10); wherein one end of the polygonal tubular body (10) is inserted into the base body (20), the extrados being on each side of the external tubular prismatic body (11) attached to the intrados of one of the sides of the polygonal base wall (22); characterized because the extrados of at least the alternate half of the sides of the internal tubular prismatic body (12) is attached and adhered to the intrados of the sides of the outer tubular prismatic body (11) by tail lines (30) perpendicular to the polygonal bottom (21) of the base body (20).
