    摘要： Double rustproof PC strand comprising
    a core wire (8) and six surrounding wires (9) twisted around said core wire (8), the wires having the following diameters:
    (A) diameter of the core wire (8): 4.42 ± 0.05 mm, diameter of the surrounding wire (9): 4.25 ± 0.05 mm; or
    (B) diameter of the core wire(8): 5.22 ± 0.05 mm, diameter of the surrounding wire (9): 5.06 ± 0.05 mm; or
    (C) diameter of the core wire (8): 5.40 ± 0.05 mm, diameter of the surrounding wire (9): 5.25 ± 0.05 mm.
    The tensile strength of the strand is 1850 N/mm 2 or higher.
    All wires were subjected to a wire drawing treatment and each wire comprises a plated layer (2). Additionally each plated wire or the strand is coated with a synthetic resin coating on an outer peripheral surface thereof.
    The PC strand has a uniform twisting pitch, durability and semi-permanent rustproof performance.

    摘要： The invention relates to a rope-like structure (10), particular a core-spun rope, a cord and a rope, wherein the individual fibers, threads, strands and/or cords are provided in the form of longitudinal fibers of a longitudinal fiber structure (40) which are joined to another fiber (50) which extends in a substantially cross-wise manner or at any particular angle in relation to the longitudinal fibers, such that the longitudinal fibers of the longitudinal fiber structure (40) are mutually non-slip and essentially cannot move backwards in relation to each other, wherein the other fibers (50) are untied, at least on one occasion, in relation to the longitudinal fibers and the latter are thus retained thereby.
