Definitions

  • the invention relates to bridges.
  • a known technique for making a bridge span consists in placing end-to-end prefabricated bridge cross sections using the cantilevered laying technique, the cantilever assembly being prestressed, the cross sections comprising a prefabricated three-dimensional lattice of prestressed concrete and the bridge span to have a slab placed on the lattice.
  • An object of the present invention is to allow the realization of a bridge by means of this technique with a length of cantilever up to 200 meters, without requiring an exorbitant launching beam.
  • the resistance of the span to longitudinal bending is ensured by the trellis, the slab participating only in the resistance to transverse bending.
  • the elementary three-dimensional lattice of prestressed concrete bars with high mechanical strength is in itself a new product which constitutes one of the aspects of the invention.
  • the bars are arranged, one in two horizontal planes superimposed with a space between the planes and the others, obliquely in this space, so as to connect the two planes, the set of bars being held in the configuration chosen by poured concrete assembly blocks.
  • the bars are placed in arrangements which one chooses at will, the most common arrangements being the arrangements along the sides of a rectangle, the arrangements along lines connecting the midpoints of the sides of a rectangle , the arrangements according to lines connecting the center of a rectangle to the vertices or in the middle of the sides of a rectangle and the arrangements according to the uprights and the bars of a ladder.
  • the most common arrangements being the arrangements along the sides of a rectangle, the arrangements along lines connecting the midpoints of the sides of a rectangle , the arrangements according to lines connecting the center of a rectangle to the vertices or in the middle of the sides of a rectangle and the arrangements according to the uprights and the bars of a ladder.
  • the bars arranged in the space between the two planes are preferably distributed one in vertical planes, the other in planes inclined to the vertical.
  • the bars connecting blocks are preferably triaxially prestressed blocks and this prestressing is preferably carried out by cables for prestressing the bars which end up at the blocks.
  • These blocks themselves can advantageously be made of prestressed concrete with high mechanical strength.
  • the slab of a bridge according to the invention can be a metal slab or a concrete slab and it is generally made up of cross sections of prefabricated slabs which are laid one after the other.
  • the cross sections are made of concrete, they are preferably combined, that is to say that the end face of a section already made is used as one of the formwork walls of the section next.
  • the blocks of two contiguous trellises are preferably conjugate blocks.
  • FIG. 1 is an example of a configuration which has been specially studied but which cannot be considered as limiting.
  • the trellis has an upper plane made up of bars P5 to P14 arranged along the sides of two contiguous rectangles, the vertices of which consist of connection blocks E to J, the common side FI and the two opposite sides EJ and GH also comprising at their middle of the connecting blocks L, M and K and, of other bars P15 to P18 connecting diagonally the block M to the blocks F and 1 and the block K to the blocks F and I.
  • the two planes are connected by rising bars starting from the lower blocks and ending at some of the upper blocks, some P21, P22, P27 and P28 located in two vertical planes determined respectively by blocks C, D, 1 and blocks A, B, F, the other P19, P20, P25 and P26 located in two inclined planes determined respectively by blocks B, C and K and A, D and M, the two planes still being connected by bars P23, P24, P29 and P30 arranged along the edges of a pyramid, the base of which is made up of blocks A, B, C and D and the top of which is made up of block L.
  • each lattice bar has been split.
  • bars are prefabricated by any suitable technique and, by way of indication, a manufacturing technique will be described below.
  • the shape and dimensions of the cross section of a bar are chosen at will. Preference is given to cylindrical bars having a diameter of the order of 25 to 35 cm.
  • the prefabricated bars are placed in the desired relative positions, forms are placed to make the connection blocks and these blocks are poured. If you want to make concrete connecting blocks with high mechanical strength, you use formwork resistant to the injection pressure of the concrete (for example 50 to 60 bars).
  • a typical trellis has a weight of 5 tonnes per linear meter for a bridge 18 meters wide. With a beam that can weigh 1,000 tonnes, we can therefore achieve a span of 200 meters.
  • Figure 2 is a vertical section of the trellis in place after a slab element V has been placed on the trellis.
  • FIG. 3 is an enlargement of one of the assembly blocks of the trellis of FIG. 2.
  • the block is triaxially prestressed by the cables 1, 2, 3 coming from the horizontal bars 4, 5 and rising bars 6 which lead to this block.
  • the prestressing cables assemble the bars and the block.
  • the prestress that existed in the bars goes into the knot and the bars create pressure constraints in the block.
  • These cables 1, 2, 3 are tensioned before, during or after the casting of the block.
  • cables such as cables 7, which are tensioned when all of the trellises of a span have been put in place.
  • cables which are overall prestressing cables, participate in the realization of a longitudinal prestressing and contribute to the overall resistance to bending.
  • Figures 4 and 5 relate to a method of manufacturing a trellis bar in which the concrete is taken from the bar in a straight tubular envelope surrounded by a hoop, compressing the concrete during the setting following the axis of the envelope with a pressure in the range 50-150 MPa, the longitudinal compression creating in the concrete transverse thrusts which put the hoop in tension around the tubular envelope.
  • FIGS. 4 and 5 there is, preferably vertically, a cylindrical tube 1 ′, for example made of thin sheet metal of the order of 2 mm or made of strong cardboard or plastic, the wall of the tube having multiple drainage perforations 4 'and this tube is surrounded by a double hoop constituted by two steel wires 2', 3 'which are wound in a helix around the tube, respectively clockwise and counterclockwise.
  • the winding 2 ' is in contact with the tube l and the winding 3' surrounds the winding 2 'but they are not tensioned.
  • Means are provided for fixing each end of a winding relative to the corresponding end of the other winding, for example by fixing the two corresponding ends on a means which also makes it possible to maintain these ends at one end of the tube 1 '.
  • An example of such a means is constituted by a circle 6 ′ which surrounds the tube 1 and which is fixed in position relative to the tube 1 ′ and to which the two corresponding ends of the hoop wires are fixed. There is such a circle at each end of the tube 1 '.
  • One or more longitudinal drains 5 ′ are placed inside the tube, which are preferably constituted by steel tubes generally thicker than the tube, when the latter is made of steel, for example a wall thickness of 4 at 6 mm.
  • the material and the thickness of the tubular casing 1 ′ are chosen so that the tube distributes the forces and resists shearing by the hoop.
  • the components are introduced into the space between the outer tube 1 'and the drain (s) 5' concrete, for example a mixture of aggregates, sand, water and cement, a mixture known per se.
  • Aggregates have, a priori, the same nature as aggregates of a conventional concrete, but are preferably chosen from the high range of aggregates of concrete: rock aggregates resistant to values between 200-300 MPa (some limestone, sandstone, etc.).
  • the binder can also be a binder such as those used for conventional concretes including resin-based binders. The percentages of aggregates and binder can be the same as those of conventional concretes.
  • the mixture is compressed at an axial pressure 7 ′ of 50-150 MPa before and during setting, until the concrete hardens, part of the water being discharged through the orifices 4 ′ of the outer tube 1 ′ and by or the 5 'drains (it should be noted that the 4' orifices can be simple pores).
  • the compression is carried out constantly or not, and continuously or not.
  • the slab will generally be made of prestressed concrete with high mechanical resistance, but it can also be metallic.
