Since the at least one plastically deformable disc of corrosion protection material as a solid disc has no through holes, in particular no through holes for passing the tension elements, they must be the plastically deformable disc during assembly pierced, whereby they are wetted on its outer surface with corrosion protection Materiai. During assembly, it is possible, for example, to proceed by initially forming the stack arrangement of support device, which forms at least one sealing disk and the at least one plastically deformable disk, and then threads the tension element through this stack arrangement.

- the value of the annular surface between about 30 mm 2 and 180 mm 2 amount.
- the modulus of elasticity of the at least one sealing disk and the resistance of the at least one plastically deformable disk to plastic deformation in each case in relation to a compressive force acting in the longitudinal direction of the tension elements are coordinated such that the boundary surfaces of the through holes of the at least one sealing disk bear sealingly against the tension elements before the at least one plastically deformable disk has been deformed by more than 5% of its measured thickness in the longitudinal direction of the tension elements.
- the at least one plastically deformable disc is assigned at least one resistance element that increases its resistance to plastic deformation.
- the at least one resistance element can be formed, for example, by an elastically and / or plastically deformable element.
- the at least one resistance element be embedded in the corrosion protection material or the at least one plastically deformable disc, for example in the form of a ring, surrounded.

- a synthetic resin coated steel wire strand For example, epoxy resin can be used as the synthetic resin, with the tension elements 14 in this case being referred to briefly in the jargon as "epoxy strands".
- the tension elements 14 are connected to an anchor plate 16, for example, made of steel in tensile force transmitting connection.
- the armature disc 16 is provided with a plurality of through holes 18, each having an inner cylindrical portion 18 a, which the side facing away from the prestressed concrete structure 12 side merges into a conical section 18b.
- Each of the conical sections 18b serves to receive a multipart ring wedge 20, which surrounds the associated tension element 14 positively and non-positively and has the task of transmitting the tensile forces from the tension element 14 to the armature disk 16.
- the armature disk 16 is supported on the outer surface 12a of the structure 12 via an abutment flange 22a of an essentially tubular anchor body 22, which is concreted into the structure 12 and can be manufactured, for example, as a cast part, in particular of cast iron.
- the anchor body 22 forms from the surface 12a of the structure 12, starting in the direction of the structure 12 into a tubular shell for the tension elements 14, which can be extended if desired in the direction of the structure 12 by means of another tube 24.

This can be achieved, for example, by matching the modulus of elasticity of the sealing disk 28 and the resistance of the plastically deformable disk 30 to each other with respect to plastic deformation with respect to a compression force acting in the longitudinal direction of the tension elements 14 in order to achieve this goal.
- FIGS. 3 and 4 show a second embodiment of a tension member according to the invention.
- the embodiment according to FIGS. 3 and 4 differs from the embodiment according to FIGS. 1 and 2 mainly in that it is not a tendon 10, as it is used in particular for prestressed concrete structures, but a stay cable, as in particular in cable-stayed structures, For example, cable-stayed bridges, extra-stretch bridges or arch bridges, is used. Therefore, in the figures 3 and 4 analogous parts are provided with the same reference numerals as in Figures 1 and 2, but increasingly to the number 100.

- the tension members 114 are connected to an armature plate 116 made of steel, for example, in traction-transmitting connection.
- the armature disk 116 as the armature disk 16 of the embodiment according to Figures 1 and 2 is provided with a plurality of through holes 118. Tapered portions 118b of the through-holes 118, which adjoin cylindrical portions 118a, serve to receive annular wedges 120 which engage around the tension members 114 in a positive and non-positive manner.
- the sheath of the tension members 114 is removed. This can be seen in FIGS.
- the armature disk 116 and the ring nut 142 together form an anchor device 144, which is supported on the outer surface 112a of the structure 112 via a bearing plate 122. More specifically, the anchor device 144 is supported on the bearing plate 122 via the ring nut 142.
- the bearing plate 122 may be made of steel, for example. Furthermore, it can be inserted into a recess provided for the structure 112 or be embedded in the structure 112. In principle, however, the anchoring device 144 can also be supported directly on the building 112.
- the tube 124 may be, for example, a smooth or a profiled plastic tube, in particular polyethylene tube, a smooth or a profiled metal tube, in particular steel tube, or the like.

- FIGS. 1 and 2 Another difference between the embodiments of FIGS. 1 and 2, on the one hand, and FIGS. 3 and 4, on the other hand, is that with the tension member or stay cable 110, the process of tensioning the tensioner 114 front operation of the activation of the sealing discs 128 and the plastic deformation of the disc 130 of anti-corrosion material! is separated, while both processes proceed according to the above description of the tension or tendon 10 of Figures 1 and 2 there simultaneously.
- the sealing washers 128 can be activated and the disc 130 of corrosion protection material can be plastically deformed by tightening the threaded nuts 151 of the threaded rods 1 52. Since the disk 130 is clamped between the armature disk 116 and the sealing disks 128, it plastically deforms, so that the corrosion protection material is automatically, i. accompanied by this second clamping operation, is pressed into the tension member 110 in its untensioned state remaining cavities, in particular in the existing between the tension members 114 and the inner walls of the through holes 118 and in the annular keys 120 cavities. Again, one can thus spare the previously required in the prior art subsequent injection of anti-corrosion material after tensioning the tension member.
