Definitions

  • the present invention relates to a pavement slab for a bridge, in particular a road bridge, which is particularly suitable for long-span bridges.
  • the pavement slab of a road bridge often consists of a reinforced or prestressed concrete slab resting on a metal framework.
  • the concrete slab can also be an integral part of the resistant section of the bridge deck and be able to support the loads resulting from the normal use of the bridge without the need to provide a support frame placed under this slab.
  • thicknesses equal to 1/30 of the free span; for example from 200 to 300 mm for spans from 6 to 9 m.
  • the capacity of these slabs is generally limited by the resistance to punching against point loads imposed by the wheels of trucks (or the axles of trains for a railway structure).
  • the weight of the floor slab quickly becomes a predominant fraction of the structure's own weight; if this weight is to be reduced, it is advisable to turn to other solutions using little or no concrete;
  • the traditionally adopted solution in suspension bridges in particular is the metal slab orthotropic; a metal plate coated with a thin layer of road surface; it is stiffened on its underside by welded troughs, generally arranged parallel to the axis of the structure. There is no support structure under the slab.
  • Tancarville bridge which has a suspended span of 600 m in span: the Robinson slab, named after its author.
  • a continuous metal sheet is used on the underside of a thin reinforced concrete slab (100 mm thick), the connection between the two materials being ensured by studs. Again, there is no support structure to provide under the slab.
  • the solution is much more economical than the orthotropic metallic slab. However, it is handicapped by the considerable number of studs to be implemented.
  • the lower sheet has no stability with respect to the buckling, and its capacity to support loads (in particular the weight of the concrete of the slab) is, at this time, very reduced. This is probably where we have to find the reason why this experience was hardly followed by other achievements.
  • the object of the present invention is to provide a pavement slab which escapes the drawbacks of the prior techniques, and in particular which, while having the advantages of lightness and resistance in the finished state of the Robinson slab, either of a lower price and can be made as part of a process comprising the construction of the bridge deck in successive stages, one of which is the pouring of concrete from the slab onto a metal plate previously put in place.
  • the present invention provides a bridge floor slab capable of supporting the loads resulting from the use of the bridge without being supported by a support structure and consisting of a continuous horizontal metal plate, forming a lost formwork.
  • a concrete slab poured on said plate anchoring fittings being fixed on the metal plate and directed upwards being at least partially embedded in the concrete to secure it to said metal plate, which has the particularity that the fittings anchor include horizontal metal beams, continuous in at least one direction, welded at their lower part to the metal plate.
  • horizontal here means parallel to the surface of the road, even if the latter is inclined.
  • the metallic structure constituted by the sheet metal and the beams is stable and resistant, which is not the case with the Robinson slab, whose studs do not cooperate with the overall resistance of the structure.
  • the weight is much lower and the length of the weld beads are two to four times less. Indeed, it is not necessary to provide a density of beams as high as that of the welded troughs, because, in the finished work, the concrete will make a very important contribution to the rigidity.
  • the metal structure alone is advantageously calculated to support by itself the self-weight of the steel and concrete assembly, so that it is not necessary, in this case, to temporarily support the deck for the pouring of the concrete .
  • the confinement of the concrete created by the presence of the beams improves both the punching resistance and the flexural strength of the slab, in comparison with the Robinson slab. It is thus possible to envisage very thin slabs, that is to say 80 to 100 mm thick on spans of 4 to 5 meters, which is the usual axis between bridge parts in a cable-stayed structure or suspended.
  • the beams can be continuous profiles, for example with an I or T section. It can also be provided that some of the beams have a structure lightened by openings in their core, or even that some of them have a lattice structure, for the purpose of greater lightness.
  • the slab will include beams arranged in two perpendicular directions.
  • essentially parallel beams for example longitudinal beams, stabilized by simple flat bars perpendicular to their direction and extending between neighboring beams. These flat bars will serve to avoid a lateral spillage of the beams when they are subjected to a significant axial compression.
  • Figure 1 is a vertical section of an orthotropic slab.
  • Figure 2 is a vertical section of a Robinson slab.
  • Figures 3 and 4 are sections perpendicular to the beams of two slab constructions according to the invention.
  • Figure 5 is a plan view of an embodiment of a slab according to the invention, before pouring the concrete.
  • Figure 6 is a plan view, similar to Figure 5, of another embodiment according to the invention.
  • Figure 7 is a section, similar to Figures 3 and 4, showing yet another embodiment of the invention.
  • Figure 1 shows in section an orthotropic metal slab, formed of a metal plate 1, covered with a thin surface layer 2, and stiffened on its underside by welded troughs 3. In general these troughs are arranged parallel to the 'axis of the book.
  • Figure 2 is a section through a Robinson slab.
  • the continuous metal plate 4 carries a series of vertical studs 5, around which a thin reinforced concrete slab 6 is poured.
  • FIG. 4 represents a variant, in which the mass of concrete 6 has been slightly reduced, so that the head 9 of the beams 7 is flush with its upper surface 10. It is obviously preferable, in this case, to provide a layer of coating (10) to protect the heads 9 of the beams against oxidation.
  • FIG. 4 there are provided, in addition to the beams 7, studs 11, similar to those of the Robinson beam, arranged between the beams 7, and intended to complete, if necessary, the joining of steel and concrete.
  • Figure 5 shows a structure in which the continuous beams 7 are connected to each other by perpendicular beams 12, so as to provide very high rigidity to this metal structure.
  • Figure 6 shows a lighter arrangement: in which a series of longitudinal beams (for example) are connected by perpendicular flat bars 13, welded both on the beams 7 and on the plate 4, so as to prevent lateral spillage beams, and therefore increase the buckling resistance of the deck.
  • the intervals between beams 7 are alternately free and provided with irons 13. Other arrangements are obviously possible.
  • Figure 7 shows a section of another embodiment, in which there is provided, in addition to the beams 7, prestressing cables 14, perpendicular to the beams, and which pass through these in holes provided for this purpose.
  • prestressing is to create a clamping force between the concrete of the slab and the lateral faces of the beams, which improves the solidarity between the concrete and the metallic structure.
  • the horizontal compression of the slab widens the punching cone created by the impact of a load, and thus makes it possible to reduce the number of beams.
  • passive reinforcements embedded in concrete. In this figure, these reinforcements are parallel to the beams 7. It is preferable to provide that they extend over a great length and cross, consequently, the transverse stiffening elements 12 or 13 that have been described above.
  • beams formed by continuous T-section profiles beams are used which are lightened by the presence of recesses in their core, the passage of the cables of prestress 14 and reinforcing bars 15 will be facilitated.
  • the panels and the main structure of the structure are then joined together by pouring joints and connectors.
