Definitions

  • the invention relates to the technical field of bridges or bridges to metal frame.
  • EP-A-501 730 FR-A-2 622,907, FR-A-2,693,491, FR-A-2,616,166, FR-A-2,698,111.
  • the metal bridges generally include a blanket, a framework and a supporting system, the roof being the part of the bridge that receives the operating costs directly and transmits them to the carrier system via possibly the metal frame conventionally formed by a network longitudinal beams (longitudinal members) and transverse beams (bridge pieces).
  • the carrier system is frequently formed by two main beams connected by spacers and provided with stiffeners.
  • Recent covers are usually formed by orthotropic slabs or mixed slabs or slabs of reinforced concrete, sometimes with transverse prestressing.
  • the orthotropic slabs are generally formed of a sheet called sheet metal decking or rolling plate more than ten millimeters thick stiffened in two perpendicular directions, by transverse bridge pieces and by equidistant longitudinal stiffeners called ribs.
  • Orthotropic slabs have some disadvantages.
  • the composite slabs comprise a continuous sheet connected to a slab of concrete, this sheet forming the lower reinforcement of the slab.
  • the connectors used are most often pistol-welded vertical studs connected at the top by steels.
  • Reinforced concrete slabs are associated with the steel by different connectors, so as to ensure the transmission efforts of the frame and a certain transverse rigidity.
  • the most common connectors are angle irons or vertical studs.
  • Bridges whose supporting system consists of metal beams and whose the cover is a slab of reinforced concrete are called mixed bridges.
  • the invention relates more particularly to such bridges or bridges.
  • the slab can sometimes rest directly on main beams braced by triangulated beams for example, the spacers that can be removed when the bridge span is small.
  • the slab of the composite bridges can in other cases be in longitudinal support on the main beams and transverse support on the bridge pieces.
  • the slab of mixed bridges may in other cases be supported on the beams main only, these beams being then bridged.
  • spans for mixed bridges ranges from 30 to 110m for continuous spans and from 25 to 90m for spans independent.
  • the invention relates more particularly to dual-girder composite bridges.
  • the beams are most often solid, the core and the soles being joined by four fillet welds.
  • the invention relates to a twin-girder composite bridge structure, in particular but not exclusively of twin-beam composite girder bridges not having the disadvantages of bridges of this type known in the art prior.
  • EP 745 740 discloses a bridge according to the preamble of claim 1.
  • the invention discloses a simple dual-girder bridge structure resistant to lateral shocks by oversized convoys for example, this structure avoiding the use of gussets and spacers, the construction said bridge does not otherwise require the stop of traffic on the tracks crossed by the bridge.
  • the bridge structure comprises two beams placed under pavement.
  • the bridge structure comprises two beams placed laterally above the roadway.
  • Each support beam may be provided with an internal reinforcement.
  • Each beam support can be developed by longitudinal welding of at least two elementary beams.
  • each support beam is produced by welding of two H-shaped beams so that the support beams have two soles substantially facing each other and parallel between them, connected by two walls of soul substantially perpendicular to the soles and facing each other.
  • each support beam is made of high-grade steel elastic and is filled with a hydraulic binder such as concrete, for example concrete high performance.
  • the support beams are assembled to the roof slab by studs placed in reservations of said slab, a support piece being placed in a reservation of the cover slab, between the upper sole of each support beam and said slab, this support piece being provided with a projecting against said upper sole.
  • a bridge deck only half of which is shown in cross-section in this figure 1 - the other half being symmetrical with the first half represented - includes a concrete slab 1, roofing, resting on two beams 2.
  • the second half of the bridge is not symmetrical to the first, and / or the concrete slab 1 rests on more than two beams 2, for example three beams 2.
  • the section plane of FIG. 1 is defined by a first direction D1 substantially horizontal said transverse and a second direction D2 substantially vertical.
  • a third direction D3 forms with the other two directions a trihedron, this third direction being said longitudinal.
  • the deck is supported by two beams 2 placed under the floor.
  • the apron is not supported only by a single longitudinal beam, or on the contrary by more than two beams longitudinal.
  • the two beams are placed laterally above the roadway.
  • the cover slab 1 is of variable thickness, in the embodiment represented: starting from a lateral longitudinal edge of this slab and going towards the center of it, the thickness increases, reaches a maximum value at the right of each beam 2 then decreases and then remains constant over a certain width of the slab.
  • a central thickness of 20cm cover slab, for a center distance E of 4.5m beams and side cantilevers 3 of about 2m can be obtained by an embodiment according to Figure 1.
  • An apron width of 8m about is thus obtained.
  • the thickness of the slab is substantially constant over its entire width.
  • the slab can be made of concrete conventional.
  • the slab is made of high performance concrete, its compressive strength at 28 days being for example greater than 80MPa.
  • the slab can be prestressed longitudinally, especially when the apron is of great width.
  • Mono strands in the voltage range of 150KN used with a step of 30cm can for example be used, the active anchors being placed alternately on one side and the other of the slab.
  • the cover slab 1 supports, in addition to the road pavement 5, longitudinal passages on the banks of cables 6 of different diameters for the telephone, electrical and other.
  • a border 7 separates the roadway 5 from the sidewalks 8 under which are placed cable passages 6.
  • only one sidewalk is provided and / or a only one of the two sidewalks is placed over cableways.
  • a railing 9 is placed at the side edge of the sidewalk (s). facing 10 is secured to the longitudinal side faces of the deck.
  • Each beam 2 is core filled with a rigid material based on binder 11, so-called “binder”, or any other material presenting mechanical characteristics comparable to those of such a binder 11.
  • This binder can be chosen from the group comprising concretes based on Portland cements, blast furnace cements, pozzolanic cements, aluminous cements, high performance concretes, concrete based on resin, fiber concretes and their equivalents.
  • binder 11 depends, among other things, on the dimensions and efforts to be taken into account for beams 2.
  • each beam 2 comprises two flanges 12 substantially opposite and horizontal, with a thickness e 12 greater than the width I 13 of the two walls 13 substantially vertical and opposite joining these two flanges 12.
  • the beams can be formed by assembling two H sections, by example HE 800A, welded together by welding beads longitudinal.
  • the beams have sections transverse polygonal, and in particular hexagonal.
  • the two walls of souls 13 are pleated regularly or not.
  • the materials used for the realization of the beams 2 can be chosen among the group comprising general purpose construction steels (and including those mentioned in standard EN-10-025), high-carbon steels elastic limit (and in particular those defined by EN-10-113), steels of structures with improved resistance to atmospheric corrosion and their equivalents.
  • the beam webs and the soles are formed by one and the same steel.
  • the cores are made of a material different from soles (eg high tensile steel for soles and general purpose construction steel for souls).
  • the beams 2 may be provided with an internal reinforcement, the fixing of the stirrups, frames and reinforcement of this reinforcement which can be at least partly internal to the beam 2 so as not to affect the visual appearance.
  • this internal reinforcement is optional, this one not being necessary for the joining of the different welded parts of the beam 2.
  • the internal reinforcement is not necessarily connected to beam 2.
  • the filling of a beam 2 by the binder 11 is generally carried out on the construction site by one of the ends of said beam 2, subsequently called end of filling.
  • a binder pump is connected by a connection to this filling end, then the binder 11 is placed in the beam 2 by pumping.
  • a vent is provided in said beam 2, this vent being preferably located in height, especially if the profile of the beam 2 is curved.
  • the beams 2 It is therefore not necessary for the beams 2 to have holes for filling on their upper surface.
  • the presence of such holes leads in general to a weakening of the metal section, especially in the provisional phase, when the beams are not yet filled with binder. Sizing of the section of the beams must take into account this weakening.
  • the invention therefore solves this problem, the absence of holes reducing otherwise the cost of manufacturing the beams.
  • filling control orifices may be made on the beams 2, these orifices being in no way used for filling said beams 2, and can therefore be of small size.
  • the filling of these beams can be partial, the role of the binder being mainly to avoid local phenomena of local buckling of the walls souls, still called blistering.
  • the width of the soles 12 was 60 cm, the height of the beams of 79cm, the beams filled with concretes being formed by assembling two sections of HE 800A welded.
  • the beams 2 are in the illustrated embodiment attached to the slab of cover 1 by studs 14 such as Nelson studs.
  • a support piece forming renformis 16 or equivalent is provided in a reservation located on the lower face of the slab 1, at the right of the sole upper of each beam 2.
  • This support piece has a bottom face 17 that is substantially horizontal, the exception of its central portion provided with a projection 18 bearing against the upper flange of the beam 2 placed opposite.
  • Two seals 19 are placed laterally between the underside 17 of the part 16 and the upper flange of each beam 2.
  • a binder, not shown, cast in the bookings 15 of the slab allows the assembly of the beams 2 to this cover slab 1.
  • Two studs or four studs may be provided depending on the loads of service provided.
  • the bridge structure obtained does not require any reinforcing spacer connecting the support beams below and away from the cover slab nor so ipso facto no reinforcement gusset between spacer and support beams, unlike twin-girder composite bridge structures known in the art prior.
  • deck widths achievable according to the described bridge structure above are quite high, nor is it necessary to bridge pieces connecting the support beams below the cover slab on which the roof slab is based longitudinally.
  • Filling steel beams with a binder greatly improves stability of these beams in large deformations, in particular during shocks by oversized convoys.
  • Prefabrication of support beams and reduction of on-site assembly makes it possible not to interrupt or modify the circulation on the paths crossed by the bridge or the bridge, which has the advantage important in the case of crossing large traffic lanes such as highways.
