Definitions

  • the invention relates to a tubular concrete structure and its application as a structure at sea.
  • the structure of the invention is, at least essentially, made up of hollow main tubes assembled by solid or hollow secondary tubes, the assembly being provided by prestressing cables of the secondary tubes which pass through the main tubes passing through the thickness of the wall of the main tubes without penetrating into the hollows of the main tubes, according to passage curves compatible with the function of these cables.
  • the prestressing cables are inside or outside the concrete of the secondary tubes.
  • the local thickening of the wall of a main tube for the passage of the prestressing cable from a secondary tube is particularly advantageous since the main tube thus offers a thickness of concrete at the arrival of the prestressing cable sufficient to avoid the punching of the main tube by the secondary tube prestressed by this cable.
  • the invention makes it possible to distribute the stresses of the assembly in the most uniform manner.
  • the passages provided in the main tubes for the prestressing cables can include sheaths facilitating the introduction of the cables.
  • the structure shown in Figure 1 consists, for example, of four main hollow tubes TP assumed to be vertical, assembled by a plurality of secondary tubes TS horizontal or oblique, in reinforced concrete, by prestressing cables C, as is see better in Figure 2.
  • the main tubes consist of sections of high-strength concrete fixed one on top of the other, which include, from place to place, N nodes for the passage or anchoring of the prestressing cables of the secondary tubes. .
  • nodes are preferably prefabricated because of their particular internal shape which is easier to make in the factory than on site.
  • Figures 3 to 12 show, by way of example, different nodes which are distinguished by their internal shape.
  • the knot in FIGS. 3 to 6 is a generally cylindrical tube, the wall of which has, in the central part of the knot, an internal bulge 1 which extends over approximately half the height of the knot and which gradually decreases towards the ends 2, 3 of the node where this wall has a constant thickness such that the hollow of the knot at these ends substantially follows the hollow of the sections (not shown) immediately below and immediately above the main tube which comprises this knot. Because of this swelling, the hollow of the knot at the location of the swelling is a cylinder D whose axis 4 is offset laterally with respect to the axis 5 of the end hollows of the knot.
  • the bulged part 1 includes, during manufacture, an internal curved passage 6 for the prestressing cable C of two secondary tubes TS and the node has external (or internal) lateral bosses 7,8 which constitute the lateral tubes bearing surfaces.
  • the bulge of a node can have any shape and any size desired depending on the number and the route of the prestressing cables in the bulge.
  • Figures 7 and 8 show an embodiment where the bulge is much smaller in height.
  • Figures 9 and 10 show an embodiment where the bulge is comparable to that of the knot of Figures 3 to 6, but is performed around the entire periphery of the node while in previous embodiments, this bulge was only carried out on a portion of the perimeter.
  • the node When the node must constitute an anchorage for a prestressing cable, it can also have any desired form of bulge but the node locally has at least one lateral surface S where the passage 6 of the prestressing cable opens and which can serve as a support for means for tensioning the cable and retaining the cable ( Figures 11,12). It is not necessary to describe these means which are well known to those skilled in the art.
  • the bulge of the wall of the main tube is on the interior side but in alternative embodiments, it is provided, according to the invention, to locate this bulge on the exterior side, if this is preferable or easier .
  • Figures 13 to 18 relate to an application of the invention to a tripod structure shown by way of example.
  • This structure comprises two long tubular posts P1, P2 and a short tubular post P3 assembled by secondary tubes TS prestressed, horizontal and oblique.
