Definitions
- the present invention relates to a connection system between a cable for a building structure and an element of this structure, the cable comprising at least one wire.
- the present invention relates in particular to cables made up of a certain number of strands themselves bringing together several wires, which are stressed in particular in tension in structures of construction work such as offshore platforms with taut lines, or suspension or guyed bridges.
- Connection systems are necessary to anchor cables, for example to the bottom of the sea.
- the accessibility of these systems is not always easy, which makes their installation costly.
- the object of the invention is to provide a connection system in which the wires are firmly anchored to resist in particular the tensile forces and this, by simple, effective and inexpensive means.
- connection system of the kind in question is essentially characterized in that it comprises: - a clamping device which is linked to the structural element, and
- each wire of the cable is firmly and simply retained when this wire is put in traction.
- the clamping device comprises at least two keys of a jaw which are supported on the force transmission device and means for compressing the jaw;
- the compression means comprise a sheath whose inner wall is of convergent shape in the direction of one end of the sheath, the keys of the jaw being of shape complementary to that of said inner wall and being mounted in the sheath to be tightened by wedge effect in the sheath;
- the keys are of longitudinal section substantially of triangular shape
- the transmission device comprises at least two plates, each of the plates carrying at least one channel of shape complementary to at least part of the shape of the cross section of the wire, the plates being mounted facing each other so that the channels of the plates form at least one passage in which said at least one wire is housed;
- a plurality of wires is housed in several passages themselves delimited by several plates (11) which are stacked one on the other to form at least one strand; - The keys completely cover the external surface of a section of the strand; -
- the transmission device comprises at least one cylindrical sleeve in which said at least one wire is housed;
- a plurality of sleeves are mounted adjacent to each other in the keys;
- the wires are made of composite material based on carbon fibers; and - the wires are solid wires.
- FIG. 1 is a general schematic view of an offshore platform comprising cables anchored by connection systems according to the present invention
- FIG. 2 is a perspective view of a first embodiment of one of the connection systems of Figure 1 according to the present invention
- FIG. 3 is an exploded perspective view of only plates of the system of Figure 2;
- Figure 4 is a longitudinal sectional view of the system of Figure 2;
- FIG. 5 is a perspective view of a second embodiment of one of the connection systems of Figure 1 according to the present invention.
- FIG. 6 is a view in longitudinal section of the system of FIG. 5.
- This platform conventionally comprises an upper part 2 which is generally situated above sea level and which is anchored in the sea bottom 3 by series 4, 5 of cables 6.
- Each cable is stretched between a constituent element 7 of the platform 1, for example to beams of the upper part 2, and an anchor block located at the bottom 3 of the sea by means of connection systems 10 which will be described below.
- Each cable is subjected to significant tensile forces while being very resistant to fatigue and corrosion.
- Each cable 6 consists, in a manner known per se, of a bundle of several strands which are themselves produced from a series of elementary wires 9. The reader will appreciate below that each cable can be reduced to one strand or even an elementary wire.
- each strand consists of a set of wires 9 which are, for example, mutually parallel at their ends.
- the strand thus formed can be joined to other strands to form the cable 6.
- Each wire 9 is made of metallic material or composite material composed of unidirectional fibers embedded in a resin matrix.
- the unidirectional fibers are preferably made of carbon and can be high strength fibers or high modulus fibers which are embedded in a crosslinked epoxy matrix, obtained for example by a pultrusion process.
- the wires 9 are of cylindrical shape with a circular base and are solid wires. They can also be of any other profile, such as a square or hexagonal profile.
- connection system 10 comprises a clamping device 11 which is linked to the structural element 7 and a force transmission device 12.
- This transmission device is subjected to the clamping forces exerted uniformly by the device clamp 11 and transmits these forces to the son 9 of the strand which are thus firmly clamped.
- the transmission device 12 consists, in the first embodiment, of a certain number of plates 15 between which the wires 9 are housed.
- Each of the plates 15 is substantially rectangular in shape and has an upper face 16, a substantially plane lower face 17 and longitudinal edges 18, taken along the thickness of the plate, of curved shape so that all of the plates 15, once superimposed on each other, form a cylinder with a circular base.
- each plate 15 constitutes in a way a longitudinal section of a cylinder which is thin compared to its length.
- Each of the upper 16 and lower 17 faces of the plates 15 has a channel 20.
- the cross section of the channels 20 is close to the half cross section of the wires 9.
- the channels 20 of an upper face 16 of a plate 15 are opposite the channels 20 of a lower face 17 of the following plate 15.
- the channels 20 thus define two by two of the passages 21 whose cross section is complementary to that of the wires 9.
- the plates 15 are made of metallic material or of composite or organic material.
- the clamping device 11 consists of a jaw 25 and of means 26 which here take the form of a sheath for compressing the jaw 25.
- the jaw 25 has several keys 27.
- the set of keys 27 define an annular base cylinder having a proximal end 28 and a distal end 29.
- the internal diameter of this cylinder is close to the diameter of the cylindrical stack of plates 15.
- the thickness of the wall at the proximal end 28 is greater than the thickness of the wall at the distal end 29.
- the proximal end is the end on which the ends of the wires 9 protrude while that the distal end is the one from which the wires extend in the direction of the rest of the construction work.
- each key 27 has an inner face 30 bearing on the plates 15 and an outer face 31 converging in the direction of the inner face 30.
- the sheath 26 is a cylinder with an annular base whose inner wall 32 is of shape complementary to that of the outer wall of the cylinder defined by the keys 27.
- the sleeve 26 has a first end or distal end 33 whose opening is of smaller diameter than the opening of the second end or proximal end 34 of this sleeve.
- the internal wall 32 of the sheath is of frustoconical shape and is complementary to the external shape, itself frustoconical, of the cylinder defined by the set of keys 27.
- the diameter of the opening of the end 33 is slightly greater than the diameter of the cylinder defined by the stack of plates 15.
- glue is applied in each of the channels 20 of the plates 15, then the wires 9 are placed in these channels and the plates 15 are stacked on top of each other.
- the stack thus produced is then inserted into the keys 27.
- the assembly is then threaded into the sheath 26 through the proximal end 34, the opening of which is of large diameter.
- the keys 27 are placed in compression by wedge effect between their external surface and the internal face of the sleeve 26 so that a predetermined clamping force is applied to the plates 15 and is transmitted to the wires 9. It is then sufficient to proceed with the glue drying.
- the predetermined clamping force on the wires 9 is a function of the slope of each of the inclined faces of the keys and of the sleeve and of the force with which the keys 27 are inserted into the sleeve 26.
- each wire 9 of a strand is firmly anchored to resist, for example, tensile forces.
- the plates 15 of the force transmission device occupy the entire interior volume of the cylinder defined by the keys 27.
- connection system 50 differs from that previously described only in the shape of the force transmission device 52, the other constituent elements are similar and bear identical reference numbers.
- the transmission device 52 no longer occupies the entire interior volume of the cylinder defined by the keys 27 of the jaw 25.
- This device consists of a plurality of metal sleeves 55 for example made of aluminum.
- the sleeves 55 have an internal diameter substantially identical to the diameter of the wires 9 so as to force these wires into the sleeves.
- the outside diameter of the sleeves is small compared to the inside diameter of the cylinder defined by the keys 27.
- the wires 9 are also glued to the interior of the sleeves 55.
- These sleeves are made of material with a low elastic limit, having a certain plasticity.
- the mounting of the connection system 50 is substantially identical to the mounting of the system of the first embodiment.
- the sleeves 55 are tangent to each other inside the keys, each of the sleeves 55 being in contact with the adjacent sleeves or a key along three generatrices. In fact, during tightening, the sleeves are slightly flattened so that each sleeve is in contact along three surfaces. Only a part of them, the peripheral sleeves, are in contact with the keys.
- the sleeves can be glued together by filling in the gaps existing between the sleeves.
- the sleeves 55 are in cross section, of non-circular external shape but close to a rhombus or the like so as to easily juxtapose the sleeves.
