Definitions

  • the present invention relates to a precast reinforced concrete slab used for the production of a bridge deck supported by a metal frame and more particularly of a bridge deck with one or more spans, the unit length of each span n ' not exceeding 45 meters.
  • Apron bridges supported by a metal framework whose unit span length is less than 45 meters are used for example for the crossing of a highway by a secondary road, and include pillars serving as support for two metal beams s' extending side by side between the pillars, to support a succession of slabs forming the bridge deck (see, for example, FR-A-2 622 907).
  • An object of the invention is to provide an improved prefabricated slab of slabs as well as a method of producing a bridge deck from such slabs, so as to simplify the construction of a bridge deck, and to reduce it the cost.
  • the slab has through passages in which nuts are anchored, in order to receive threaded rods capable of resting at one end on the beams to constitute screw jacks making it possible to provide sufficient space. between the slab and the beams in order to introduce a cement mortar serving as a foundation for the slabs, after adjusting the inclination of the slab on the beams.
  • the slab is produced by molding a reinforced concrete block of generally elongated parallelepiped shape, having reinforcements extending outside an opposite front edge and a rear edge of the slab , at least one of the front and rear sections of the slab having a recess providing access from above to the reinforcements of two contiguous slabs arranged front section against rear section, for their connection by pouring a concrete joint in said recess, the front and rear edges having below said recess a projecting edge and a tuck-in edge of generally complementary shapes so that the contiguous rear and front edges of two adjacent slabs constitute a formwork for pouring the concrete joint into said indentation, without the need to bring back a formwork wall from below.
  • the slabs have a shape of a non-rectangular parallelepiped such that the front and rear edges extend parallel to said line joining the supports of the two beams on the same pillar.
  • the slab has vertical stops on the underside for laterally docking at least one of the two beams with a view to centering the slab.
  • these vertical stops are received removably in sockets anchored in the slab.
  • the slab comprises on at least one of its front and rear sections two docking stops, each arranged in the vicinity of a lateral face of the slab and in front of the reinforcements, proper to avoid impacts from slabs of slabs.
  • the slab comprises connection cells in which the reinforcements extend naked, arranged so as to come opposite the beams when the slabs are laid on them, two of these cells also opening onto a edge of the slab in order to have a sufficient connection surface with the beams without weakening the slab.
  • the present invention also relates to a method of implementing the aforementioned slabs to make a bridge.
  • FIG. 1 shows a bridge referenced 1 as a whole, with two spans, the unit length 1 of each span not exceeding 45 meters, the bridge being used for example for crossing motorway lanes 2 by a road secondary 3.
  • the deck 1 comprises an apron 4 resting on a metal frame itself supported at its longitudinal ends by pillars or abutments 5a, 5b and in the middle by one or more pillars; only one pillar 6 has been shown in the figures, for the sake of clarity of the drawings.
  • the foundations of the abutments 5a, 5b and of the pillar 6 have also not been shown for the sake of clarity of the drawing.
  • the framework of the bridge rests on the abutments 5a and 5b and on the pillar 6 by means of jacks or support devices 7 constituting temporary supports allowing the compression of the bridge during manufacture, in a known manner and as will be explained below.
  • FIG. 2 is a partial schematic top view of the bridge shown in Figure 1, by A the axis of the highway and R the axis of the secondary road. It is noted on examining FIG. 2 that the axes A and R do not intersect, in the particular embodiment described, at right angles, but at an angle.
  • the deck 4 comprises a succession of slabs of slabs 8 in accordance with the invention and arranged side by side on two metal beams 9 of the framework of the bridge.
  • the beams 9 extend parallel to the axis R of the secondary road and rest by their longitudinal ends on the abutments 5a and 5b, not shown in Figure 2 and oriented parallel to the axis A of the highway, the supports respective 10a and 10b of the beams 9 on the two abutments 5a and 5b being offset axially on the axis R. More specifically, the supports 10a and 10b are respectively arranged on each abutment 5a, 5b along a line L extending parallel to the axis A of the highway.
  • the framework of the bridge also usually comprises spacers, not shown, extending between the two beams 9.
  • the beams 9 conventionally have a cross section in the shape of 1, comprising horizontal lower and upper flanges connected by a vertical core.
