Definitions
- the present invention relates to structural cables used in the construction of engineering structures. It finds in particular applications in the prestressing, bracing of sections of structure, or even in suspension bridges.
- Modern structural cables are often made up of strands unitary tension, wires or strands, arranged in quasi-parallel bundles in ducts or in the open air. Given the aggressiveness of the environment exterior and durability requirements, these cables typically have anticorrosion protection layers: oil, galvanization, lubrication, waxing, filling with elastomeric materials or cement grout, or metal or plastic outer sheathing.
- the protections made at the unit strands have several advantages by electrically and mechanically insulating the strands cables. This insulation avoids electrical bridging, generalized corrosions to a section of cable by "gangrene effect", the lateral contacts of the bending zones where the pressures between strands can create stress concentrations harmful to good static strength or dynamic. It also avoids lateral contacts in the rectilinear parts when the strands are free to move.
- the individual protections of the strands can take the form of a sheathing: sheathed-greased strand in prestressing application, strand guyed structure self-protected, or even coherent strand (EP-A-0 855 471).
- the individually sheathed strands are positioned with their sheaths in a mass of injected and hardened material, such than a cement grout, which forms a mechanical spacer (see EP-A-0 220 113, EP-A-0 437 143, EP-A-0 465 303).
- a mass of injected and hardened material such than a cement grout, which forms a mechanical spacer.
- the object of the present invention is to propose a mode of protection of strands constituting a structural cable, which is compatible with various applications and various types of strands.
- the invention thus provides a work structure cable of construction, comprising at least one bundle of strands stretched substantially parallel contained in at least one section of protective sheath in material plastic, in which the plastic of the sheath section extends between strands to form a consistent strand spacing matrix.
- the protective plastic sheath thus plays the role mechanical spacing of the strands, and constitutes an individual sheath for each strand.
- Another advantage is to allow to dispense eventually sheath injection operations after the strands have been put in place, generally expensive and delicate operations.
- Another aspect of the present invention relates to a section of structural cable sheath for construction work, which constitutes a semi-finished product before the introduction of the strands.
- This section of sheath forms a coherent spacing matrix having longitudinal holes substantially parallel adapted to each receive a stretched cable.
- the matrix can be made of plastic. It can also include a part made of injected material such as a cement grout. In this last case, it can for example include individual plastic tubes intended to receive the stretched strands, arranged in an outer tube, with the injected material filling the outer tube around the individual tubes.
- Yet another aspect relates to a method of installing a structural cable in a construction work, in which a sheath having at least one section forming a coherent spacing matrix having substantially parallel longitudinal holes, we engage respective strands in at least some of the orifices of the sheath section, and tension the strands.
- the strands can be engaged in the orifices of the sheath section by pulling on guides previously threaded in the holes, or by pushing. Their tensioning can be individual or collective. Each strand can be extracted and / or replaced separately if necessary.
- Figure 1 shows a section of sheath 1 formed by a shaped part general cylindrical plastic, pierced with longitudinal holes parallels 2.
- Each orifice 2, of cylindrical section receives a metal strand 3 of the cable.
- the example drawn in Figure 1 is a cable made up of 19 strands non-contiguous parallels arranged in hexagonal arrangement, only one of which is represented.
- the sheath section 1 has a cylindrical outer shape in the example of figure 1. This shape could still be profiled so optimize its aerodynamics. If the structural cable is exposed to the outside of the structure, this external shape can, in known manner, be provided with elements or reliefs, for example helical, making it possible to reduce the risk of deformation by rain and wind.
- the sheath consists of a single section extending over the entire length of the cable between its two anchored ends, or of several sections successively assembled mechanically, for example by means of fishplates or sleeves, or butt welded. In the latter case, we can plan indexing marks to position the sections before assembly.
- the plastic material of the sheath section 1 may be a polyolefin such as high density polyethylene (HDPE). It can also be resin base (epoxy for example).
- the sheath section 1 is for example manufactured by extrusion. Each section can be installed on a road or sea freight transport to bring it to the construction site of the work. It can also be wound on reels, allowing the transport of long lengths to the construction site of the structure.
- the plastic of the sheath section 1 can also be composite and for example manufactured by coextrusion.
- the periphery of the sheath is made of a material chosen for its properties of surface resistance (resistance to impact, climatic conditions, soiling, when the inside of the sheath is chosen material for its viscoelastic properties (it then helps to dampen vibrations individual strands), and / or for its low coefficient of friction with strands, which facilitates their installation.
- the sheath formed by section 1 or by several sections of this type put end to end preferably extends over the entire length of the part cable run between the two end anchors.
- An appreciable advantage of the invention is that each individual strand cable can be removed and replaced using a relatively small device simple, similar to that used during the initial threading, which facilitates control and maintenance operations.
- the stretched strands 3 of the cable may be metallic wires or bare steel strands, as shown.
- a product of filling such as petroleum wax or synthetic grease, protecting steel against corrosion.
- This product may be the same as that injected into the anchoring devices at the ends of the strands, which ensures uniformity and continuity of anti-corrosion protection.
- the strands 3 can also be strands individually protected, which can then simply be threaded into the sheath. Protection can be an epoxy resin coating the constituent wires of the strand, an envelope plastic material adhering to the steel of the wires, or a casing made of plastic material not adhering to steel associated with a flexible product which protects steel against corrosion and lubricates the steel-steel contact areas and steel-plastic.
- Protection can be an epoxy resin coating the constituent wires of the strand, an envelope plastic material adhering to the steel of the wires, or a casing made of plastic material not adhering to steel associated with a flexible product which protects steel against corrosion and lubricates the steel-steel contact areas and steel-plastic.
- the strand anchoring devices provide a packing type sealing system, as described in the request EP-A-0 323 285, and strip the ends of the strands beyond this sealing system to anchor them firmly to the structure.
- the transverse arrangement of the holes 2 intended to receive the strands is advantageously regular to limit the transverse size of the cable. However, it could also be irregular.
- the outer profile of the sheath is not necessarily circular.
- the Figures 2 and 3 thus show, without limitation, sheath sections 1 to polygonal exterior profile.
- the hexagonal shape in Figure 2 allows you to making bundles each comprising a sheathed set of strands, which can easily be assembled in parallel to form cables relatively large section.
- the rectangular shape of figure 3 is suitable in some prestressing applications where cables are required strip shape.
- the section of sheath in which will be strung the metal strands is achieved by arranging a set of individual tubes 4 into an outer tube 5, and by injecting a material curable 6 in the intervals remaining in the outer tube 5 around the individual tubes 4.
- the interior of the tubes 5 then forms the longitudinal orifices 2 of the matrix formed by the sheath section.
- Injection and hardening material can take place in the factory or on the construction site of the work. After hardening, the strands are threaded (before or after installation of the sheath in the place assigned to it in the structure), anchored, then tensioned.
- the tubes 4 and 5 are for example made of HDPE, and the injected material 6 may be a plastic resin preferably having properties viscoelastic after hardening. In a variant, the material injected 6 is a cement grout.
- One or more of the orifices 2 provided in the sheath may not contain strand, but serve as a vent or channel for receiving organs such as optical fibers or sensors.
- the sheath then incorporates functions usually fulfilled by attached devices.
