no. 1 approach

[0069] In the first embodiment ( Figure 4 )middle:

[0070] The bearing surface 8E comprises a portion of the surface of the first hole 8C sized to fit watertightly on the second end 6D of the tubular member 6, the watertight annular element 7 surrounding the sheath 2E of the strand 2B retaining Therein, this bearing surface 8E is located adjacent to the bearing surface 8D of the drilled element 8 intended to limit the axial insertion of said end 6D of the tubular element 6,

[0071] The annular element 7 houses a watertight bearing surface 7A surrounding the sheath 2E of the strand 2B, sized to fit in the hole 8C of the drilled element 8 in such a way that it can be placed on the one hand. Between the bearing surface 8D of the element 8 and, on the other hand, the end face 6F of this end 6D, the bearing surface 8D of the element 8 serves to limit its insertion on the end 6D of the tubular member 6 .

[0073] In the third embodiment ( Figure 6 and 7 ), that is, in the preferred embodiment, the drilled element 8:

[0074] In one aspect, at least two parts 81, 82 are included, namely,

[0075] A first part 81 comprising a first hole 8C dimensioned to fit watertightly on one end 6D of the tubular member 6 and a bearing surface 8D intended to be fitted by at least indirect pressure Axial insertion on said end 6D is restricted by resting on the end face 6F of said end 6D, and

Abstract

A device (1) is disclosed for anchoring one end (2A) of a stay (2) to a base (3), this end of the stay comprising at least two strands (2B) which diverge from its longitudinal axis (2C) in such a way as to come to be anchored in the device, these strands each being made up of a core wire (2D) and a protective sheathing (2E), the device itself being intended to be positioned and immobilised in translation in a bore (3A) provided in the base, this device comprising a first rigid unit (4), which: is delimited transversally by a cylindrical face (4A) and longitudinally by two opposite faces (4B, 4C) substantially orthogonal to the longitudinal axis (4D) of said first unit, is traversed by perforations (4E) which, made substantially parallel to its longitudinal axis, are each intended for passage of one end (2F), devoid of sheathing, of a strand of the stay, and each including a bearing surface (4F) intended to co-operate with an immobilisation piece (4G) of such an end devoid of sheathing, bears at least one tubular element (5C) to cover, over a certain distance (L1) measured from one (4C) of its opposite faces, the bundle of strands in a water-tight way at least in its part where the strands are devoid of sheathing.

Description

technical field [0001] The present invention relates to a device for anchoring one end of a retainer to a base, commonly referred to as an anchor head. [0002] Retainers refer in particular, but not exclusively, to cables used to construct suspension and retention structures such as suspension bridges, cable retention bridges, stadium roofs, buildings, telecommunication towers and the like. [0003] The holder can also be a cable for ground anchors. (A ground anchor consists of one or more steel tension members, sheaths, encapsulated and embedded within a hardenable material such as sand slurry poured into a prepared borehole in the ground.) [0004] This holder makes it possible to connect the parts of the structure respectively by the action of means designed for this purpose at the bases which have been prefabricated for anchoring the ends of the holder. [0005] The invention also relates to a method for producing a device of the type described above. [0006] More spe...
