Thus, the first stops 33 and second stops 35 make it possible to identify when the rimpedement between the first floating module 3 and the second floating module 5 is sufficient, in particular in order to ensure sufficient compression of the sealing device 102 interposed between the first floating module 3 and the second floating module 5, in order to ensure the sealing of the space 106.
  • the mechanical connection step that is to say the connection of the first metal reinforcement to the second metal reinforcement by the coupler 34, as well as the connection between the first prestressing sheath and the second prestressing sheath by the sleeve 36, is facilitated if the emptying step has been carried out beforehand, in the case where the first floating module 3 and the second floating module 5 are assembled on a body of water.
  • the thickness of the hollow 104 corresponding to the first dimension 30 of the cavity of the first floating module 3 as well as to the first dimension 30 of the cavity of the second floating module 5, is equal to the second dimension 32 of the wall 2 of the first floating module 3.
  • the thickness of the hollow 104 is equal to a third dimension 32' of the wall of the second floating module 5, the third dimension 32' being measured between the external face 16 and the internal face 17 of the wall 2 of the second floating module 5.
  • this configuration makes it possible to ensure total mechanical continuity between the first floating module and a second floating module, and to obtain a modular floating structure which behaves like a monolithic structure having the same mechanical resistance as the current section of a floating module, the floating structure thus presenting a continuity of material, along the entirety of the second dimension 32 and the third dimension 32' between the first floating module 3 and the second floating module 5 through the hollow 104, the hollow being intended to be filled with concrete, the thickness of the hollow 104 being equal to the second dimension 32 and the third dimension 32'.
  • the trough is aligned along the vertical axis Z with the wall 2 of the first floating module and the wall 2 of the second floating module.
  • the external face 16 of the wall of the first floating module 3 and the external face 16 of the wall 2 of the second floating module 5 are in the same plane, said plane also being the plane of extension of the internal face 20 of the first extension 29 of the first floating module 3 and the internal face 20 of the second extension 31 of the second floating module 5.
  • the internal face 17 of the wall of the first floating module 3 and the internal face 17 of the wall 2 of the second floating module 5 are in the same plane.
  • FIGS. 9 And 10 illustrate a partial view, respectively in section and in perspective, of an exemplary embodiment of a floating structure 100 conforming to the second aspect of the invention.
  • FIG. 9 illustrates the floating structure 100 in the third plane F, the Figure 9 thus being a top view.
  • the floating structure 100 illustrated is formed of at least the first floating module 3 and the second floating module 5 visible to the figures 7 And 8 .
  • the coupler 34 and the sleeve 36 installed, as illustrated in figures 7 And 8 , thus providing the mechanical connection between the first floating module 3 and the second floating module 5, a material, in particular concrete, is poured into the hollow 104 so that the first floating module 3 and the second floating module 5 form a monolithic assembly . More particularly, the first longitudinal end 4 of the first floating module 3 is connected by the concrete poured in the hollow 104 to the second longitudinal end 6 of the second floating module 5.
  • the hollow 104 being formed by the first cavity 19 and the second cavity 21, extends along the first dimension 30.
  • the first dimension 30 being equal to the second dimension 32 corresponding to the thickness of the wall 2
  • this configuration allows the concrete present in the hollow 104 to take up forces mechanical, particularly in compression, because it ensures total mechanical continuity between the first module floating and a second floating module, and to obtain a modular floating structure which behaves like a monolithic structure having the same mechanical resistance as the current section of a floating module, unlike a known configuration in which the first dimension of the hollow does not represents only a portion of the thickness of the wall.
  • the prestressing sheath 24 opening into the hollow 104 is thus covered by the concrete present in the hollow.
  • the prestressing cable 25 inserted inside the prestressing sheath 24 extends in the longitudinal axis of the wall of the first floating module 3 and of the wall of the second floating module 5, inside said walls , thus allowing the compressive force exerted by the tensile force applied to the prestressing cable to be centered in relation to the wall of the first floating module 3 and the wall of the second floating module 5, in particular in comparison with a known configuration in which the prestressing cable extends longitudinally on the external face or on the internal face of the wall of the first floating module and of the wall of the second floating module, the compressive force exerted by the tensile force applied to the prestressing cable then being eccentric.
  • a floating structure 100 advantageously having an extension 14 defining a cavity 18 on each of its walls, has high resistance to mechanical forces in compression, provided by the concrete poured in each cavity 18, which makes it possible to ensure total mechanical continuity between the first floating module and a second floating module, and to obtain a modular floating structure which behaves like a monolithic structure having the same mechanical resistance as the current section of a floating module.
  • each wall 2 of the first floating module 3 being connected to a wall 2 of the second floating module 5 by a concrete hollow 104 crossed by a metal frame 22 and/or a prestressing sheath 24 inside which there is a tensioned prestressing cable 25, the floating structure 100 has a high resistance to the shearing and bending movements which are exerted between the first floating module 3 and the second floating module 5, in particular due to the movements caused by waves at the level of the body of water on which the floating structure 100 rests.
  • THE figures 11a and 11b illustrate a first assembly mode and a second assembly mode, respectively, between a first floating module 3 and a second floating module 5 intended to be assembled to form a floating structure 100.
  • the figures 11a and 11b illustrate top views, along the third plane F, of the first floating module 3, the second floating module 5 and the floating structure 100.
  • the figure 11a illustrates a substantially rectilinear floating structure 100 formed by a first floating module 3 and a second floating module 5 similar to each other, and extending mainly in the same direction.
  • FIG 11b illustrates a floating structure 100 comprising an angle 57.
  • the angle 57 formed is a right angle, that is to say whose value is equal to 90°, the angle being measured between the main extension axis of the first floating module 3 and the main extension axis of the second floating module 5 with which the first floating module 3 is assembled to form the floating structure 100.
  • the floating structure is formed by a first floating module 3 and a second floating module 5, the first floating module 3 comprising the angle 57, the second floating module 5 being substantially rectilinear.
  • the first floating module 3 thus comprises an extension 58 extending perpendicular to the main axis of extension of the first floating module 3.
  • the second floating module 5 is connected to the extension 58 of the first floating module 3, thus allowing the formation of the floating structure 100 comprising the angle 57.
  • This configuration thus makes it possible to obtain a wide variety of floating structure conformations, the angle not being limited to the value of 90° but being able to take any value, in particular between 90° ° and 180°, an angle of 180° then forming a rectilinear floating module.
  • THE figures 12a to 12e illustrate examples of embodiment of a floating structure 100 conforming to the second aspect of the invention. More particularly, the figures 12a to 12e each illustrate a form that a floating structure conforming to the second aspect of the invention can take, according to the third plane F. In other words, the figures 12a to 12e are top views of the floating structure 100 illustrated in each of said figures, each floating structure 100 comprising in particular several floating modules 1 conforming to the first aspect of the invention.
  • the floating structures illustrated in figures 12a, 12b, 12c, 12d and 12e form, respectively, a square, a rectangle, a regular hexagon, a circle, and a floating structure taking approximately the shape of a “V”. It is understood that the floating structure 100 can take any other form without departing from the scope of the invention.
  • the floating module comprises an extension emerging from the external face of a wall, the extension extending longitudinally projecting from a longitudinal end of the wall, the extension and the wall from which the extension comes being produced by continuity of material.
  • the present invention makes it possible to connect two floating modules made of reinforced and prestressed concrete in water, so as to ensure total continuity of the concrete, reinforcements and prestressing steels between the two floating modules connected to each other with the same mechanical resistance as the current section of a floating module. It can be used to obtain a floating monolithic structure of any shape in concrete from a modular construction. The connection obtained is watertight and capable of resisting, for the different phases of the structure's life, the static and dynamic forces, the hydrodynamic forces, and the fatigue phenomena applied to it in accordance with international regulations.
  • This invention can be used in the construction of bridges, oil platforms, ports, piers, floating platforms for renewable energies, in nuclear power and in any other field.
