Definitions

  • the present invention relates to a new bridge structure consisting of an apron and means for supporting this apron, and in particular to a new cable-stayed bridge structure of large span, as well as to a method of constructing such a bridge.
  • suspension bridges In the current state of the art, the crossing of large spans uses either suspension bridges or cable-stayed bridges.
  • Suspension bridges are economically justified for exceptional spans, but their flexibility poses problems for traffic, especially rail, and for aeroelastic stability.
  • Cable-stayed bridges for their part, do not exhibit the wind sensitivity of suspension bridges, particularly if the deck is constructed of concrete, a material which gives the structure sufficient weight and great rigidity. The weight, however, limits the spans, so that beyond the field of application of concrete cable-stayed bridges, decks with a mixed steel / concrete structure or entirely metallic decks have been used.
  • guyed decks with a mixed steel / concrete structure have always consisted of an upper concrete member forming a paving slab, carried by transverse and longitudinal stiffening beams intended for transferring the loads to the guy wires. while ensuring sufficient rigidity to the deck.
  • Lattice structures can also be used, because they make it possible to economically obtain great bending and torsional rigidity, while ensuring maximum transparency with respect to the wind.
  • such trellis structures generally combine steel and concrete, but despite considerable research in this field, no truly satisfactory solution has been found to transfer the forces between the members and the diagonals at the different nodes of the trellis. The long-term behavior of such solutions is unknown and cost prices remain high.
  • the object of the invention is to overcome all the drawbacks mentioned above, by proposing a new structure which is both light, rigid, and easy to produce, therefore economical.
  • the invention provides, to obtain this result, a bridge consisting of an apron, and means for supporting this apron, the apron comprising: - an upper chord forming a circulation slab, - a lower chord forming a continuous longitudinal element, - connecting beams, called “diagonals" connecting the upper and lower members, directed obliquely both with respect to the vertical and with respect to the length of the bridge, and forming, with the members, a spatial trellis, this bridge having for the particularity that the axes of the diagonals converge on the longitudinal axis of the lower member or the median plane of the upper member.
  • spatial trellis is meant a structure made up of elements which can be assimilated to parts of a plane or to straight line segments and linked together, this structure not being included in a plane.
  • nodes the junction points of plane parts and / or line segments.
  • the parts of members which are subjected to significant tensile forces, and the diagonals which are subjected to significant tensile forces are prestressed by means which are specific to each of said members and to each diagonal or to two concurrent diagonals. .
  • the means of prestressing the diagonals comprise prestressing reinforcements anchored at their two ends at the points of junction of these diagonals with the upper member and drawing a V whose middle is at the point of junction of said diagonals with the lower member, the lower chord is formed from successive assembled sections and is provided with longitudinal prestressing reinforcements which each compress several assembled sections, -
  • the means for prestressing the upper member are constituted by prestressing frames connecting together the nodes of the space lattice formed by the junction points of the diagonals with said upper member.
  • the deck that has just been described can be integrated into bridges of various designs.
  • a cable-stayed bridge is preferred, and in this case provision is made for the means for supporting the deck to be constituted by guy wires connecting support masts to nodes of the space trellis formed by the junction points. diagonals with the upper chord.
  • the bridge comprises at least two continuous lower members, and an equal number of spatial trusses comprising diagonals whose axes converge on the axis of a lower member, said members being interconnected by a bracing, these spatial trusses each including a part of the upper chord, and advantageously, that this bridge comprises two lower chords and two spatial trusses and in that the means for supporting the deck consist of guy lines connecting the nodes of the spatial trusses which are located in the axial plane of the bridge to support masts.
  • the means for supporting the deck consist of guy wires connecting support masts to nodes of the spatial trellis formed by the points of junction of the diagonals with the lower member.
  • the invention can also be applied to bridges with much smaller spans, and not guyed.
  • the means for supporting the deck consist of transverse supports on which the upper frame rests, and additional prestressing frames are provided which follow a polygonal path connecting two successive transverse supports passing through reference points located on the lower member, and, advantageously, said additional prestressing reinforcements are not in the axial plane of the bridge.
  • folded sheet gussets comprising two wings which are each in a longitudinal plane containing the axis of diagonals which are fixed on it, the gusset being fixed on the lower chord so that the fold axis of the gusset wings coincides with the longitudinal axis of the lower chord.
  • the lower member is also made for the lower member to be formed from successive sections assembled, and at least some of the gussets are fixed to the points of assembly of successive sections.
  • gussets comprising a lower wing situated in a longitudinal plane containing the axis of the diagonals which are fixed on him, and an upper wing which is fixed on the upper chord, so that the fold axis of the wings of the gusset is in the median plane of the upper chord.
  • the gusset carries anchor points for diagonal prestressing reinforcements and anchor points for prestressing reinforcements of the upper member
  • the connection between the gusset and the upper chord is a concrete-steel connection
  • the upper wing of the gusset has its median plane located in a longitudinal plane containing the axis of shrouds supporting the point, these shrouds being fixed on said gusset. It can also be provided that the upper wing is split into two parallel wings between which the shroud is fixed, the fold axis being in this case formed by the intersection of the median planes of the upper and lower wings.
  • the upper chord may also be made for the upper chord to constitute a concrete slab reinforced by continuous metal sections and prestressing reinforcements arranged perpendicularly to these metal sections.
  • the upper chord of the structure forming a pavement slab or carrying railway traffic is made of reinforced or prestressed concrete; the lower chord can be either in reinforced or prestressed concrete, or in a mixed steel / concrete structure, or entirely metallic. It is advantageous to use a metal tube filled with concrete, the characteristics of which are described further on.
  • the lower and upper members are interconnected by a series of diagonals located in two oblique planes forming an isosceles triangle in the cross section.
  • the two edges of the upper slab have the anchors of the suspension shrouds at regular intervals, at the point of intersection of the diagonals mentioned above.
  • the invention further provides an original construction method, adapted to the bridge structure which has just been described.
  • This process includes the following steps: - place, on an already assembled part of the deck, two longitudinal beams with a temporary border, on either side of the upper chord, in cantilever with a length at least equal to the longitudinal dimension of a mesh of the space trellis, each beam being held by two successive nodes of the space truss already assembled, - bring a new spatial lattice mesh, this mesh comprising at least one node located on the lower member, two nodes located on the upper member, and the diagonals corresponding to these nodes, - securing this new mesh and the part of the deck already assembled, supporting the new mesh using the temporary edge beams, - repeat the operations by advancing the provisional border beams along the mesh that has just been fixed.
  • a suspension guy wire is also fixed on said new link.
  • the bridge according to the invention comprises an apron 1 consisting of a series of triangular spatial elements suspended from guy lines 2, at regularly spaced points. These shrouds are fixed towards the top of the support masts 3. For the sake of clarity, the central span is shown with only eight elements suspended by three shrouds on either side of the key. In long-span bridges, the spacing of the stays is variable from 10 to 20 m and the number of stays in the central half-span can reach 20 to 25.
  • the cross section of the deck 1 shown in Figure 3 is an isosceles triangle consisting of an upper slab (or chord) 4, a lower chord 5 and diagonals 6, without intermediate supports of the upper slab 4 between the two banks of the bridge.
  • the plan view of FIG. 4 also shows that the planes of the diagonals are cut into all identical triangles, the vertices of which are alternately located on the edges of the upper slab 4 and on the lower central member 5.
  • the lower member 5 the details of which are given in FIG. 6, is broken down, for the production of the structure, into sections of equal length separated by joints allowing rapid assembly during construction.
  • the lower chord 5 is, in the example described, a metal tube 7 whether or not filled with concrete, depending on the location along the length of the bridge and the nature of the stresses that stress it.
  • ordinary reinforcements or prestressing reinforcements - passive reinforcements embedded in concrete in areas where the compression force is important to reduce the stress in the materials, - pretensioned reinforcement put in tension before pouring the concrete and anchored on the end flanges of each section of tube, intended to place the metal tube under permanent longitudinal compression, - post-tensioned prestressing reinforcements, placed under sheath 8 inside the filling concrete and intended to put the whole of the metal tube and the filling concrete under permanent longitudinal compression, - Post-tensioned prestressing reinforcements 9 placed outside the tube and stretched in the structure over several sections after assembly of these.
  • the assembly between successive sections of the lower member is made by flanges 10 placed opposite one another and joined longitudinally by high-strength bolts 11.
  • the end flanges of each section further include a gusset 12 folded according to the plane of the oblique diagonals allowing assembly by welding of these with the lower main chord.
  • the flanges finally include and as necessary the anchors of the external prestress of the lower chord.
  • the axis of folding of the gusset 12 coincides with the axis of the tube 7.
  • At least some of the sections of the tube are filled with concrete.
  • the tube filling concrete if it exists, can be used before or after assembling the frame in the structure. In both cases, it is advantageous to compress the filling concrete inside its metallic envelope to combat the subsequent effects of shrinkage and improve the relative adhesion of the two materials. Contrary to works using a composite metal tube / concrete filling member where the variations in force and consequently the adhesion stresses occur continuously along the member, in the object of the invention, such variations in force appear only at the right of the connecting nodes with the diagonals, in an area where the arrangements used make it impossible for any relative sliding of the concrete and the tube. For this purpose, stiffeners or connectors 13 are provided in the vicinity of the flange.
  • an injection device 14 is provided in the joint between two successive sections, to ensure perfect transmission of the longitudinal forces in the filling concrete .
  • the essential element of the assembly is a gusset 15 in folded sheet, the upper part of which coincides with the suspension plane of the shrouds 2, and the lower part is located in the plane of the oblique diagonals 6.
  • the shroud is fixed there by known means such as yokes 16 and axis 17 or, depending the variant shown in Figure 13, by a splitting of the gusset allowing the fixing of the lower anchor of the stay.
  • the diagonals are easily linked to the gusset by welding along a slot made in the tube.
  • the fold edge 18 of the gusset is located in the mean plane 19 of the floor slab.
  • the gusset also carries the anchors 20, 21 of the frames 22, 23 of the diagonal 6 and of the upper slab 4. According to the invention, the transmission of all the forces is thus carried out along a direct path, eliminating any welding or any assembly working at tearing which always presents a potential risk.
  • the continuous gussets provided ensure an interpenetration of the members and the diagonals to achieve the direct path of the forces mentioned above.
  • the proposed arrangements ensure direct transfer of all the loads and complete continuity of all the efforts of the shrouds, the two members and the diagonals.
  • - intermediate posts 24 make it possible to reduce the spans of the roadway, therefore its thickness, its weight and its reinforcements, - transverse bridge parts 25 bringing together for example the two connection gussets on the banks to divide the floor slab into panels working in both longitudinal and transverse directions.
  • the shrouds 2 pass through the upper chord 4 through guides 26 designed to dampen the vibrations of the system, and are anchored in the lower chord, at the location of the nodes of the spatial trellis formed by the junction of the diagonals with the lower chord.
  • FIG. 19 there are two parallel lower members 5, and two spatial trusses each consisting of a lower member, of one half of the upper member 4 which is above this lower member, and of diagonals 6 which connect each lower member to the upper member half which corresponds to it.
  • a bracing 27 connects the two lower members 5 and stiffens the assembly by ensuring the continuity of the external contour and the stability of the cross section, and the torsional rigidity of the deck.
  • the floor slab itself is made up of a mixed structure comprising continuous metal sections and concrete placed between them, the materials being joined together by a prestress orthogonal to the direction of the sections.
  • the confinement conferred on the concrete of the slab by the metal profiles allows the minimum thickness of the slab to be reduced to 0.10 m without the risk of puncturing under the concentrated loads of the vehicles.
  • the method according to the invention can be extended to making non-guyed spans.
  • Figures 22 and 23 describe the construction of a typical span in elevation and cross-section respectively.
  • the longitudinal bending strength is imparted in the members by prestressing reinforcements such as 23 in the upper member and 9 in the lower member, supplemented as necessary by external prestressing members 30 of polygonal outline and overlapping at right supports constituted by crosspieces 31 carried by piles 32 and adjacent to diagonal junctions 6 at the upper frame 4.
  • prestressing reinforcements 30 connect points 33 located on the crosspieces 31 near their ends, this is that is to say near the nodes of the spatial lattice formed by the junction of the diagonals to the upper chord, passing through deflection points 34 which are other nodes of the spatial lattice, constituted by the junction of the diagonals to the lower chord .
  • the resistance to cutting forces is supplemented by a prestressing of the diagonals such as 22, according to an embodiment identical to that which has been described for a guyed structure.
  • the devices of the invention allow a remarkably simple embodiment, shown schematically in FIGS. 24 to 27.
  • the new frame section is transported and placed by known means (upper chord, four diagonals and two upper gussets provisionally joined by a cross beam ensuring the spatial rigidity of the element) which rests in its final position on the end of the two provisional longitudinal beams.
  • the upper gussets are then immobilized on the beams by pins (allowing at the same time the adjustment of the profile along the structure) and suspension bars, then a new stay cable is put in place.
