Abstract (en)
Stirrup structure (1) shaped like a broken spiral, extending according to its longitudinal axis (A), constituted by a sequence of tracts substantially perpendicular (3) and substantially oblique (2) with respect to the longitudinal axis, forming winding configurations, with the oblique tracts (2) tilted two by two in directions different between them to implement the spiral pitch (D) and positioned on faced surfaces, with which implementing the method consisting in handling the single stirrup structure (1) in an axially compacted state, in positioning it in the site on a resting base or inside a form, in positioning inside thereof the reinforcement longitudinal members, in releasing the stirrup structure (1) from the ties in order to allow it extending elastically, then in fastening it with anchoring means to the reinforcement longitudinal members. <IMAGE>
