Definitions
- the present invention relates to anchoring devices for fixing structural cables to building elements.
- the invention is applied whenever it is necessary to fix a cable subjected to tensile stresses, to equip construction elements such as cable-stayed, suspension or other bridges, by connecting the tops of the pylons of these bridges to their decks and their anchor blocks.
- the cables usually encountered in such construction elements comprise a plurality of strands which each include metal wires themselves wrapped together in a protective sheath, each of these protective sheaths being interrupted at a terminal section so that the strands each have a stripped end section.
- the anchoring devices usually encountered, and in particular in EP-A-0 323 285, include:
- the tube transversely delimiting a chamber inside which the end sections of the strands are located and which is filled with a material ensuring the protection of the stripped end sections present in the chamber
- the cable gland which tightly closes the chamber, opposite the anchoring block, and which is tightly crossed by the sheathed strands, the cable gland comprising:
- At least two perforated plates one of which is said to be internal, is disposed on the side of the chamber and the other is said to be external, which is disposed opposite the perforated block with respect to the internal plate, and
- At least one packing cushion which is interposed between the inner and outer plates.
- the internal plate of the cable gland is fixed while the external plate is movable and is driven towards the fixed plate by means of threaded rods. crossing the perforated block and put in traction. These rods are both screwed into the outer plate and into a nut that abuts the perforated block.
- the present invention aims to remedy the aforementioned drawbacks by providing an anchoring device facilitating maintenance operations.
- an anchoring device of the kind in question is essentially characterized in that the outer plate is fixed relative to the chamber and in that the device comprises means for bearing on the inner plate .
- the support means on the inner plate comprise a compression rod, one end of which abuts on the inner plate and the other end of which passes through a hole in the perforated block and can be actuated from the side of the perforated block which is opposite the integral scope of the building element;
- the compression rod is a threaded rod and the hole is tapped, the rod being actuated by screwing;
- the compression rod is in abutment against an interposition plate mounted adjacent to the inner plate;
- the support means comprise a stop which is integral with the tube and which is located inside the tube at a distance from the outer face of the outer plate substantially equal to the thickness of the cable gland and in which said at least one gland cushion is perforated by passages of diameter less than the diameter of the sheathed strands;
- the stuffing box is placed in a groove made inside the tube and the stop is defined by the projection between the groove and the running part of the tube;
- the outer plate is in abutment against a stop sleeve added by screwing to the end of the tube; - The outer plate is in abutment against a perforated plate attached to the end of the tube; the protective material is in compression in the chamber; and
- a cover is mounted in leaktight manner on the perforated block, delimiting a chamber in which the stripped end sections of the strands project, the chamber being filled with said protective material.
- FIG. 1 is a general schematic view of a suspension bridge whose cables are immobilized with anchoring devices according to the present invention
- FIG. 2 is a cross-sectional view of a cable of Figure 1;
- - Figure 3 is an enlarged sectional view of one of the strands constituting the cable of Figure 2;
- - Figure 4 is a longitudinal sectional view of a first embodiment of the cable anchoring device of Figures 2 and 3;
- - Figure 5 is a longitudinal sectional view of a second embodiment of the anchoring device for fixing the cable of Figures 2 and 3; and
- FIG. 6 is an enlarged sectional view of the cable gland of the anchoring device of FIG. 5.
- the building element 1 shown in Figure 1 is for example a suspension bridge.
- This bridge conventionally comprises an apron 2, two pillars or pylons 3, two parallel carrying cables 4, only one being visible in the figure, and a plurality of hangers 4a which are attached to the cables 4 and which carry the apron 2.
- the carrying cables 4 are stretched between two solid anchors to the ground 9 located at the two ends of the bridge, and they are supported by the two pylons 3. As shown more particularly in FIG. 2, the cable 4 considered is composed of a plurality of individual strands 5.
- Each strand 5 is itself formed, as shown in FIG. 3, of a plurality of elementary wires 6, for example seven in number.
- These wires can be parallel or twisted and are for example made of galvanized or galfanized steel. All of these wires are surrounded by a protective sheath 7 which is able to protect them during their entire life against corrosion due to weathering or other external attack, and in particular to humidity and handling.
- This sheath is for example made of a plastic material, such as polyethylene or a polyamide, or a metal such as aluminum or stainless steel.
- the sheath is directly attached to the bundle of wires by extrusion.
- the sheath in question can also be formed by any other desirable coating of the wire bundle 6, for example by an epoxy paint coated on it.
- the intervals between the wires 6 and the sheath 7, if they exist, may or may not be filled with a protective substance 8 such as, for example, a resinous pitch of the epoxy type or a wax or polybutadiene.
- the sheathed strands 5 thus defined are all identical to each other, are autonomous and remain so throughout the life of the cable 4 which they constitute.
- the sheathed strands 5 of the cable 4 are individually tensioned, in a manner known per se, on the bridge 1.
- the assembly is ensured using spun sleeves or, as shown in FIGS. 4 and 5, by clamping the ends of the strands 5 in split jaws 10.
- each of the protective sheaths 7 of the strands 5 is interrupted at the level of an end section T so that each strand 5 has an exposed end section 11.
- the stripped end sections 11 are clamped in the split jaws 10 which each have on the one hand, a tapped cylindrical hole suitable for contiguously surrounding the end of the strand to be anchored and on the other hand, a frustoconical external surface suitable for cooperating with an additional housing provided in a perforated anchor block 15.
- Each strand 5 is thus tensioned between, for example, a pillar 3 of the bridge 1 and the perforated block 15 secured, for example, to one of the anchoring blocks 9 of this bridge.
- the perforated block 15 has two opposite faces: an outer face 16 and an inner face 17.
- the outer face 16 is turned away from the strands 5.
- the ends 12 of end sections 11 project from this face.
- the inner face 17 is turned towards the strands 5 side.
- the terminal sections T of each of these strands are located inside a chamber 20 delimited:
- a rigid tube 22 which is for example of cylindrical shape with circular base and which is screwed or welded at one of its ends to be adjustable or fixed relative to the inner face 17 of the perforated block 15; - And at the axial end opposite to the block 15, by a cable gland 25 which is sealed through the sheathed strands 5 and which is pressed tightly against the inner face 23 of the tube 22 under the effect of axial compression.
- the cable gland 25 consists, in a manner known per se, of three perforated plates 26, 27 and 28 between which are interposed two cushions 29 and 30 made of elastomeric material or the like.
- the perforated plates 26 to 28 are rigid plates of plastic material and the assembly of plates and cushions extends transversely to the strands 5 so as to be crossed by them.
- the plate 26 is an outer plate located at the end of the tube 22 facing the current part of the cable, that is to say on the side from which the strands 5 extend in the direction of the pylon 3. This plate is held in a fixed position relative to the chamber 20 being in abutment against a return 32 formed at one end of the tube 22.
- the plates 26 to 28 maintain the cushions 29,30 in compression to inflate the edges of the cushions and ensure the desired seal.
- support means 35 cooperate with the plate 28 closest to the chamber 20, also called the inner plate.
- the support means 35 consist of an interposition plate 36 which is perforated and which is applied against the internal plate 28 and of threaded rods 37
- the threaded rods take the form of screws each provided with a head
- a first end of the threaded rod or screw 37 is in abutment against the interposition plate 36 while the second end of the rod 37 passes through a tapped hole formed in the perforated block 15, so that the head 38 protrudes on the outer face 16 of this block.
- the threaded rod 37 can be actuated by means of the head 38 to be screwed through the tapped hole.
- the intermediate plate 36 is pushed back by screwing the threaded rods or screws 37. During this compression, the interposition plate 36 moves the inner plate 28 by bringing it closer to the outer plate 26 which, itself, remains fixed.
- an adjustment tube 40 is mounted integral with the external face of the tube 22, in the vicinity of the end of this tube adjacent to the perforated block 15 while a ring 41 is attached by screwing onto a complementary thread formed on the adjustment tube 40.
- This ring is in axial abutment against an annular bearing surface 42 forming part of the anchoring block 9.
- the adjustment tube 40 is for example welded or screwed on the tube 22 while the perforated block 15 is screwed on the adjustment tube by means of screws 43 accessible from the outer face 16 of this block.
- a cover 45 is mounted in leaktight manner on the external face 16 of the perforated block 15 and is held thereon by means of screws 46. This cover delimits a chamber 47 in which the ends 12 of the sections of stripped end 11 of the strands 5 and which contains a flexible material for protection against corrosion of these ends.
- the chamber 47 is filled with protection against corrosion through an orifice which is then closed by a plug 48.
- the chamber 47 communicates with the chamber 20 by passages made in the perforated block 15
- each strand 5 is autonomous over its entire length and can be stretched or relaxed independently of its neighbors.
- the ends 12 of these strands are easily accessible from the outer face
- the cushions 29 and 30 can be periodically easily put back into compression to maintain a good seal thanks to the screwing of the heads 38 of the screws which are easily accessible from the external face 16 of the block 15. The operator does not have to dismantle certain constituent parts of the anchoring device described above for accessing hidden parts.
- the second embodiment shown in Figures 5 and 6 differs from the previous embodiment only by the shape of the support means 35, the diameter of the passages formed in the cushions 29 and 30, and the end of the tube opposite the block anchor.
- the strands 5 are inserted into the cushions 29 and 30 through passages 50 which have a diameter slightly smaller than that of the sheath 7 of the strands 5.
- a groove 51 is formed at the end of the tube 22 which is opposite to the anchor block 15.
- the tube 22 thus has at its end an inner diameter section which is greater than the internal diameter of the rest of the tube.
- a projection 52 is defined by this change in diameter.
- the three perforated plates 26 to 28 and the cushions 29 and 30 are inserted into this groove 51 by the end of the tube 22.
- the plates and the cushions are in abutment against the projection 52 and are held in compression against each other at by means of a stop sleeve 53.
- This sleeve is attached to the end of the tube 22 and is held by means of a thread 54 which cooperates with a thread formed inside the end portion of the tube.
- a perforated plate replaces the stop sleeve and is screwed to the end of the tube 22.
- This plate contains as many perforations as there are strands to be inserted in the cable gland.
- the perforated plate is provided with perforations in a number greater than the number of strands.
- the material of the chamber 20 is put in compression so that the inner plate 25 of the cable gland is pushed back towards the outer plate which itself remains fixed.
- the cushions 29, 30 are thus compressed more strongly, strengthening the seal.
