Definitions

  • the present invention relates to cable-stayed bridges with a concrete deck, intended in particular to cross spans of the order of 80 to 250 m, and the construction of such bridges.
  • the deck of such cable-stayed bridges consists of a concrete box suspended at regular intervals by guy lines which themselves transmit the load to pylons located on either side of the breach. to cross.
  • the shrouds can be located in the median plane of the structure, between the traffic lanes. The stability of the apron under the influence of asymmetrical loads when only one traffic lane is loaded is then ensured by the torsional resistance of the apron.
  • the shrouds are placed on either side of the deck in two vertical planes, or oblique and also inclined on either side of the axis of the structure to allow the shrouds to converge in a single point on the pylon head.
  • the deck In the case of this double lateral suspension, recent embodiments have appeared to simplify the construction of the deck and reduce the cost thereof.
  • the deck When the main span is sufficiently small (of the order of 100 to 150 m minimum), the deck then consists of a simple solid concrete slab suspended along its two lateral edges.
  • the limits of use of this solution are given by the excessive flexibility of the deck vis-à-vis the risk of general buckling or for the operation of the structure.
  • the low transverse rigidity of the slab does not always ensure the stability of the structure vis-à-vis the wind in a satisfactory manner.
  • the deck was made up of a slab ribbed in the transverse direction and provided with longitudinal edge beams in which the shrouds are anchored.
  • Such aprons are in principle easier to produce than box aprons. However, they do not have the same longitudinal rigidity in bending and above all their torsional inertia is negligible. The effects of accidental phenomena such as exceptional wind gusts, impact of a vehicle against a shroud, therefore have much more serious consequences on these structures.
  • the decks can be formed of successive prefabricated elements assembled to each other in the longitudinal direction.
  • This less expensive method of construction does not appreciably affect the rigidity and the above remarks remain valid in this case, provided, of course, that the prefabricated elements are made rigidly secured to one another.
  • the deck is formed of prefabricated elements which can be hollowed out in the width direction of the bridge, and which bear on each other only by their upper part, whereas their lower part rests on a support cable stretched in the direction of the length of the bridge. It is clear that such an arrangement, if it were applied to a cable-stayed bridge, would in particular have insufficient resistance to forces directed upwards and resulting from the effect of the stay cables.
  • the object of the present invention is to overcome the limitations or inadequacies recalled above, authorizing the production of works whose rigidity is comparable to boxed aprons, while retaining the simplicity of form and construction of full or ribbed slab aprons.
  • the bridge is made up of a series of adjoining transverse boxes, and no longer of longitudinal boxes or of flat, simple or ribbed slabs.
  • the result, for equal weight, is a very high torsional rigidity of the apron.
  • the elements are joined together to constitute the deck is made by all conventional means, and in particular by longitudinal prestressing cables extending over several successive elements and / or over the entire length of the deck.
  • each of these is a prefabricated one-piece element formed by a lower table and an upper table which carries the floor, separated by interior voids extending over a large part of the transverse dimension of the element, the two tables being joined together by walls and, optionally, longitudinal and transverse partitions.
  • each of these comprises a prefabricated part consisting of a lower table and transverse and longitudinal vertical walls or partitions, horizontal slabs resting on said walls or partitions, and a continuous upper slab the along the deck, cast on the slabs and carrying the floor.
  • the first embodiment provides time and productivity savings thanks to further prefabrication.
  • the second embodiment allows easy replacement of the floor slabs if necessary, which is advantageous especially in countries with a harsh climate, where it is subjected to the attack of de-icing products.
  • the batteries Due to the high torsional rigidity of the deck, the corresponding forces are transmitted at a distance, in particular to the abutments and the piles. It is advantageous to give the batteries a structure which makes them capable of absorbing these forces. For this, provision can be made for the stack carrying the pylon to extend upwards to the deck and support both at least part of the deck and the pylon.
  • each stack to carry the part of the deck or decks which is closest to the longitudinal axial plane of the bridge and the part of the decks which is the most separated from the longitudinal axial plane of the bridge is supported by additional stay cables situated approximately in a transverse vertical plane and connecting the deck to the summit area of the pylon.
  • This structure is formed in a transverse plane, and is therefore perpendicular to the longitudinal triangles formed by the deck, the pylon and the conventional shrouds.
  • At least one of said additional stay cables is deflected at the top of the pylon and comes to hang on the opposite edge of the deck.
  • the fixing and tensioning of the additional shrouds is thus done at the deck, which facilitates assembly.
  • these are hinged together or are rigidly linked together in line with the pile, and at least one of said additional stay cables is diverted to the top of the pylon and clings to the opposite edge of the same deck, near the longitudinal axial plane of the bridge.
  • the head of the pylon is of increasing complexity with the number of layers of cables, in particular if it must support the additional cables mentioned above, and which are in planes perpendicular to these layers.
  • the pylon head is a metallic piece which has, in its upper part, a saddle-shaped surface and on which the deck support struts resting side by side are deflected to go to two attachment points located on the apron approximately symmetrically with respect to the pylon, the middle part of said metal part having a cavity which contains the means for anchoring or deflecting the additional stays.
  • the head of the pylon comprises, for each cable ply, a deflection assembly situated in the plane of this ply and comprising at least one part crossed by a number of deflection passages equal to the number of shrouds, these passages being superimposed on each other, and the means for anchoring or deflecting the additional stay cables being placed between the deflection assemblies.
  • the means for securing a stay cable with an element of the deck comprise a plate, flat as a whole, bearing by a first face against the deck, and bearing on the second side means for anchoring the guy, means for preventing sliding of said plate on the deck, and at least one prestressing cable, or an anchoring rod, directed approximately perpendicular to the plane of said plate, this cable passing through said plate and being retained by abutment against it, and crossing the apron to be in abutment against the opposite side of the apron.
  • the deck has a flat support surface for the plate, this flat surface being parallel to the stay and to the longitudinal axis of the bridge, with a central hollow part, the plate carries, on its face in contact with said bearing surface, a projection which penetrates into said hollow part and which contains the means for hooking said prestressing cable, and the prestressing cable enters the apron at the bottom of said hollow part and will hang on the transversely opposite edge of the deck.
  • the edges of the prefabricated elements all have parallel bearing surfaces, and making with the vertical the same angle as the corresponding cable ply.
  • the orientation of the metal anchoring part is the only difference from one prefabricated element to another, in the event that this part is put in place during casting.
  • the plate is intended to be supported on a horizontal surface of the deck and bears on the face opposite to the deck, fittings for hanging a shroud obliquely to the horizontal, and the prestressing cable or cables or anchor rods pass through the deck down.
  • This embodiment saves space in the transverse direction, it facilitates assembly, control and possible replacements.
  • the metal attachment parts must be individualized, unless a pivot system is used.
  • the bridge structure according to the invention allows a particularly advantageous construction method.
  • a temporary frame is put in place fixed on a part of the deck already built and supported by the shrouds, this frame advancing in cantilever beyond said already built part and being supported by a mounting cable. connecting the top of the pylon to the end of the provisional frame furthest from the part already built, and said provisional frame is used to put in place and fix new deck elements, the length of the mounting cable being modified when the temporary frame is moved.

The number of intermediate partitions 14 is not fixed, it may depend on the dimensions of the element 10. The intermediate partition 14 may not even exist. Between the walls 13 and the intermediate partition 14, there are voids 15, which serve to reduce the weight of the element and to improve the efficiency of its load-bearing section with respect to the longitudinal flexions of the structure. It will be observed that the section of the deck is symmetrical with respect to a horizontal plane.
