摘要:
The invention concerns a device comprising a rigid housing (2) connected to the structural element and enclosing at least partially the cable (6), a wedging structure (3) arranged between the cable and the housing, load transmitting means (4, 13, 14) arranged to exert a longitudinal compressive stress, parallel to the cable, on the wedging structure. The wedging structure is pressed against the cable and the housing under the action of the longitudinal compressive stress, so as to provide resistance to the movement of the housing and the structural element parallel to the cable.

The invention concerns a reinforcement for a building works structure (1) comprising an assembly of solid wires (13, 14). The wires are mutually parallel to form a bundle and the reinforcement comprises a sheath (12) made of plastic material enclosing the bundle and providing it with cohesion.

The invention relates to a method of erecting a structure 0 comprising at least two prefabricated concrete elements 1, 2, the method comprising: • installing a first concrete element 1; • installing a second concrete element 2 with at least one spacer piece 4 maintaining a gap between respective end faces 104, 203 of the first element and of the second element; • tensioning at least one rod 105, 3 held on the first and second elements and passing through the gap maintained by the spacer piece; and • introducing a curable interface product 5 into said gap. The method thus makes it possible to move the need to wait for the joints between the assembled components to have cured between two assembly operations off the critical path of the construction process. Incidentally, a significant reduction in the time taken to erect such a structure is achieved.

The invention concerns an anchoring device for fixing a structural cable to a building element, said cable comprising a plurality of strands (5) each comprising metal wires (6) which are themselves enclosed together in a protective sheath, each of the protective sheaths being interrupted at a terminal edge (T) such that the strands (5) have each an exposed end section (11). The exposed sections are inserted in a sealed enclosure (20) with a packing box (25) whereof one plate (26) is fixed and the other plate (28) is compressed by threaded rods (37).
