<p>The invention concerns a tension member (5) for structures, in particular a cable stay for a cable-stayed bridge (2), in which one or more tension elements (10), such as steel rods, steel wires, or stranded steel wires, run inside a tubular sheath (8). The tension elements (10) fill only a portion of the cross-section of the tubular sheath (8), so that a remaining unoccupied area (11) is left. In order to prevent the tension elements (10) from moving in the transverse direction with respect to the tension member (5), there is arranged in the remaining unoccupied area (11) of the tubular sheath (8) a filler body (12, 12') that extends over a limited longitudinal section (L) of the tension member (5) and includes a deformable sheath (13, 13'), which tightly encloses a hollow space that is delimited on all sides and can be filled with a filler medium (27). The invention further concerns a method for producing such a tension member (5), in which, after an axially delimited longitudinal section (L) has been established, an empty filler body (12, 12') is introduced into the remaining unoccupied area (11) between the tubular sheath (8) and the tension elements (10), and, finally, the filler body (12, 12') is filled with a filler medium (27) until the remaining unoccupied area (11) isfilled in the region of the selected longitudinal section (L).</p> |
