Definitions

  • the present invention relates to a fire protection device for a cable or the like of a civil engineering structure, of the type comprising a mat of thermally insulating material wrapped around the cable.
  • the invention applies in particular to the bridge deck maintenance cables such as guyed and extradossed cables, as well as the prestressed cables extending outside the deck deck concrete.
  • the specifications for the construction of bridges include fire protection requirements for the bridge deck maintenance cables. For example, the exposure of a cable at a temperature of 1000 ° C for one hour should not cause an increase in the temperature of the cable itself beyond 100 ° C.
  • the invention aims to provide an economical solution, reliable and easy to implement, even around cables already in place, which is capable of meeting the most stringent requirements in terms of fire safety.
  • the subject of the invention is a fire protection device of the aforementioned type, characterized by the characterizing part of claim 1.
  • the invention also relates to a civil engineering structure, of the type comprising a wired structure, characterized in that at least one cable or the like of the wired structure is provided with a fire protection device such as as defined above.
  • a fire protection device such as as defined above.
  • the invention particularly relates to a bridge, of the type comprising an apron, towers and a set of cables or similar suspension of the deck to the pylons, characterized in that at least one cable is provided with a device fire protection as defined above.
  • the pylon associated with said cable has at its upper part a deviating cable tube, and the protective device extends to the deviating tube.
  • the cable 1 shown in Figures 1 and 2 essentially consists of a large number of strands 2 contiguous to each other, for example, as shown, in a hexagonal general outline.
  • Each strand 2 itself consists of several elementary strands 3 of steel surrounded by a sheath 4.
  • a protection device 5 is used which will be described below.
  • the device 5 comprises an inner protective mat 6 made of thermally resistant material, wrapped around the cable and closed edge to edge, along a generatrix 7. This inner mat is held in place by a series of adhesive strips 8 made of glass fibers.
  • the device 5 also comprises an outer protection mat 9 also made of thermally resistant material.
  • This outer mat is wound around the inner mattress 6, with a recovery zone 10 between its two marginal regions. The whole of this zone 10 is firmly fixed by gluing by means of a layer of thermally resistant glue 11 such as the glue marketed under the trademark "MILLE”.
  • the fixing of the outer mattress 9 is completed by strapping by means of a series of steel strips 12 arranged at regular intervals.
  • similar strapping (not shown) can complete the fixing of the inner mattress 6 before the introduction of the outer mattress.
  • each mattress consists of a succession of sections placed end to end, and the junction planes 13A of the outer mattress are offset longitudinally with respect to those 13B of the sections of the inner mattress.
  • each of the two mattresses consists of a product marketed under the trademark "MICROTHERM”. It is a microporous structure consisting of silica particles, metal oxides and glass filaments, this thermally insulating structure being arranged in a stitched glass fabric envelope forming a flexible mattress.
  • Such a set of two superimposed mattresses can withstand 1000 ° C in steady state and can withstand 1200 ° C for brief exposures to a fire.
  • the device can be completed by a second inner mattress similar to the mattress 6, interposed between the mattress and the outer mattress, and provided with fixing means such as the adhesive strips 8.
  • the fire protection device is completed by an outer shell 14 made of HDPE (high density polyethylene) having on the one hand a protective function of the insulation blankets against moisture, and on the other hand an aesthetic function.
  • HDPE high density polyethylene
  • the shell 14 itself consists of two identical half-shells 14A, 14B comprising along one end generator a recess 15 and, along the other end generator, a rib 16 adapted to s' snap into the recess 15. To seal, strips 17 forming gaskets are interposed between the facing faces of the two half-shells.
  • the shell 14 consists of a succession of sections welded end to end by welding to the mirror.
  • the Figure 3 represents an end of an angled deflector tube 18 in which passes the middle portion of the cable, at the top of the associated pylon 19.
  • the tube 18 has an end portion 20 which projects out of the pylon.
  • the space remaining free in the tube 18 is filled with a grout of cement 21.
  • the combination of the two mattresses 6 and 9 penetrates into a protective tube 22 fixed to the pylon, which surrounds the projecting portion 20 and extends beyond it.
  • a similar fire protection 23 is disposed around the portion 20.
  • the continuity between this additional protection and the outer mat 9 of the current portion of the cable is obtained by means of a connector 24 made of the same MICROTHERM material.
  • the shell 14 stops at a short distance from the inlet of the protection tube 22, and the aesthetic continuity is obtained by means of a section of HDPE tube 25 fixed in the extension of the tube 22, and in which fits the end of the shell 14.
  • the fire protection is provided to the inside of the deviator tube and has no weak point at this location.
  • the insulation blankets are extended to the anchoring device provided at each end of the cable in the bridge deck.
  • the protection device described above is reliable and simple to implement, both during the construction of the bridge that during a possible maintenance or repair operation, or to improve the protection or fire initially planned during the construction of the bridge.
  • the double fastening 10-11, 12 of the outer mattress 9 provides a high degree of safety of the fire protection device.
  • each section of the shell 14 may consist of more than two sectors, for example three or four sectors.
