Definitions

  • the invention relates to concrete structural elements having a very high permissible working rate, say at least 50-100 MPa (megapascals).
  • the tube and the hoop remain integral with the compressed concrete element obtained and it is therefore very important that this tube and this hoop be as inexpensive as possible.
  • a hoop consisting of a tubular sheath of crossed wires mutually blocked at least at the ends of the sheath.
  • This hoop and the tube can come together from manufacturing.
  • Two embodiments are particularly advantageous, one in which the hoop is formed by plies included in a hardened synthetic resin, all the plies and hardened resin constituting the tube, and the other in which the hoop is a product. knitted fabric which constitutes both the hoop and the tube.
  • the device shown in FIG. 1 comprises a tubular mold 1 to be filled with concrete and compression means for exerting axial compression on the concrete before the concrete is set.
  • These pressure means comprise for example two pressure plates 2,2 ′ situated at the ends of the mold and means for pushing or pulling these plates towards one another.
  • These means are for example one or two cylinders 3.3 ′.
  • one of the plates is kept fixed and the other plate is pushed or pulled towards the fixed plate. It is convenient to use a cable 4 to pull the plates towards each other under the action of the jacks.
  • one or more longitudinal tubes 5 are provided in the concrete, for example for the passage of the cable 4, for the drainage of water from the concrete or for other uses.
  • the mold 1 is constituted by crossed plies of wires coated with a hardened synthetic resin.
  • the resin constitutes a means for mutually blocking the strands of the plies.
  • Figure 2 there is shown schematically a portion of such a hoop consisting of two or more plies 6,7 crossed at about 90 ° and wound in inverted helices.
  • the wall of the tube is provided, preferably during manufacture, with small holes 8 to facilitate the dewatering of the concrete during its compression.
  • the resin constitutes a first protection of. the fret.
  • the hoop is a cylindrical braid.
  • Figure 3 there is shown schematically a portion of such a hoop consisting of two bands 9,10 braided together so as to form inverted turns crossed at about 90 ° and to form windows 8 between the ribbons.
  • the strips are mutually blocked, at least at the ends of the tube, by an adhesive agent.
  • Such a hoop has a double advantage: the braid itself constitutes the molding tube and the windows constitute the orifices for discharging the water from the concrete. This embodiment is therefore even more advantageous than that of the resin tube with plies included in the wall of the tube.
  • each strip consists of two superimposed ribbons and at each crossing of the two strips, one of the strips of a strip passes between the two strips of the other strip.
  • the invention is not limited to a particular crossing angle of the wires, nor to a particular means for blocking the wires with respect to each other at the ends of the tube or elsewhere (glue, welding, anchoring, etc.) and does not is not limited to the embodiments which have been described.
  • Figure 4 shows an alternative embodiment in which the hoop is a grid consisting of a series of annular transverse wires 11 joined by longitudinal wires 12, all of the wires being blocked by a resin (not shown in the figure 4).
  • steel or carbon wires are preferably used, for example with a diameter of approximately 0.1 to 0.5 nm or glass fibers.
  • the resin tube or the braid is filled with liquid concrete and an axial compression of at least 50 MPa is exerted on this concrete before setting of the concrete: the frets lengthen under the effect of the thrust of the concrete caused by the axial pressure and, after the setting of the concrete, the frets tend to return to their initial dimension creating a biaxial stress transverse to the axis of the tube.
  • the mold used for the manufacture of the elements is a mold which remains incorporated in the molded element, it is particularly important that the cost of manufacturing this mold is as low as possible, which is achieved by the present invention.
  • the molded products are notably characterized by the fact that the concrete constitutes a compressed mass surrounded by a hoop constituted by a sheath tubular 1 of crossed wires, in particular as described above with reference to FIGS. 2 to 4, which exerts a stress on the concrete in transverse planes.
  • the concrete elements produced according to the invention are useful as bars, beams and other rigid structural elements, but a particularly advantageous application of the invention is the manufacture of concrete cables.
  • the cable is formed ( Figure 6) by arranging in line cable sections M molded in accordance with the invention and by assembling these sections by a common prestressing cable which passes longitudinally through all of the sections.
  • the same cable is used as that used to compress the concrete in the tube before it sets and which passes through the tubes 4.
  • the common prestressing cable can advantageously be made of carbon fibers coated with hardened synthetic resin.
  • the concrete cable has a diameter of 15 to 20 cm, possibly more.
  • the invention makes it possible in particular to manufacture a concrete cable for making anchor lines, stay cables and bridge carrying cables.
  • anchor lines in particular for offshore platforms, by means of steel tubes, having a diameter of the order of 40 to 60 cm and a wall thickness of 2 to 3 cm. , which consist of sections of tubes welded or mechanically linked and wound on a reel.
  • the present invention makes it possible to replace these tubes with concrete elements which, for at least equivalent performance, can have a much smaller section, a substantially lighter weight, and no longer need to be assembled by welding or mechanically.
  • the cables of the present invention due to their smaller diameter, have a much weaker wave grip than that of steel tubes. Finally, these cables are much less susceptible to corrosion than steel cables.
  • the cable sections M can be separated by intermediate elements but while remaining assembled by the overall prestressing cable.
