APPARATUS FOR DE-ICING THE CASING TUBE OF A TENDON AND PREVENTING ICE FORMING ON SAID TUBE, TENDON COMPRISING AN APPARATUS OF THIS TYPE, AND STRUCTURE COMPRISING AT LEAST ONE TENDON OF THIS TYPE

摘要

An apparatus for de-icing the surface of a casing tube of a tendon that is exposed to weather influences, or to guard against, if not completely prevent, ice forming on the tube, where the tendon is anchored to a structure by means of an anchoring device is provided. The apparatus includes a power device, one end of which is in force transmitting engagement with the anchoring device or with a part that is connected to the anchoring device in an operationally stable manner, and the other end is in force transmitting engagement with the casing tube or with a part that is connected to the tube in an operationally stable manner. The power device is configured to move the casing tube relative to the anchoring device in the circumferential, radial and/or axial direction in relation to the longitudinal extension direction of the casing tube.
