tensile modulus, tensile modulus particular zero point

摘要

tensile modulus (10), in particular tensile modulus of zero, with a base body (12), with an elevation (14) of bolt type, on the side of the base body for engaging a clamping ring (16), with at least two turnbuckle runners (26), guided in the base body (12) radially relative to a central longitudinal axis (28) which can move to a position radially external to latch the clamping ring (16) on the base body (12) and at a position radially releasing inside to release the clamping ring (16), especially with a removable adjusting element (30) which drives the turnbuckle runners (26), wherein for coupling motion the turnbuckle runners (26) with the adjusting element (30), the adjusting element (30) or the sliding tensioning has (n) guide grooves (46, 48), which are located in planes (42, 44) extending in the direction of movement of the sliding tension and are ConfiguRAD symmetrically as the central longitudinal axis (28), wherein in the turnbuckle runners (26) or the adjustment element (30) there are provided guide cams (50, 52) engaging in the guide grooves (46, 48), wherein the turnbuckle runners (26) each have a radially outer functional segment and a radially inner functional segment, wherein the radially inner functional segment extending laterally along the central longitudinal axis (28) and is configured thinner on the side facing the adjusting element (30) the functional segment radially outward, and wherein the radially inner functional segment is there provided with the guide cam (50, 52) or the guide groove (46, 48).
