Spacer for tension member

Spacer for an axially elongated tension member, such as a prestressed concrete tendon, a diagonal cable for a stayed girder bridge or the like, the tension member comprising a plurality of individual tension elements, such as steel wires, rows or strands, extending in the axial direction of said tension member and disposed in spaced parallel relation in an ordered array with certain tension elements disposed radially outwardly from other tension elements and the tension elements located within an axially extending tubular sheath having an inside surface, wherein the improvement comprises a star-shaped base comprising a central part and a number of angularly spaced arms extending radially outwardly from the central part, said central part and arms having a length in the radial direction of said tubular sheath slightly smaller than the radius of the inside surface of said sheath, said central part and said arms forming triangular shaped openings extending in the axial direction of the sheath for receiving at least one of said tension elements and said arms having radially outer ends with said outer ends being circumferentially spaced apart so that said openings are open at the radially outer ends of said arms, a plurality of said individual tension elements located within each of said triangular openings and including at least one said other tension element and at least two said certain tension elements, intermediate parts separate from said base and each located within one of said triangular openings for spacing said individual tension elements therein, said intermediate parts comprising a flange extending in the circumferential direction for spacing apart said certain and said other individual tension elements in the radial direction and at least one web extending radially outwardly from said flange for spacing said certain individual tension elements apart in the circumferential direction.
