ESTRIBO IN SPIRAL PARTY AND METHOD TO PERFORM THE REINFORCEMENT OF CONCRETE STRUCTURES.

摘要

Split spiral stirrup for the reinforcement of concrete structures, comprising a spiral structure (1) with extension along its longitudinal axis (A), made with a metal bar, consisting of a sequence of substantially perpendicular sections (3) and substantially oblique (2) with respect to said longitudinal axis (A) and forming winding configurations with polygonal projection on a plane substantially perpendicular to said longitudinal axis (A), characterized in that said oblique sections (2) are inclined two by two in directions different from each other in order to perform the spiral passage and are positioned on facing surfaces.
