Definitions

  • the present invention relates to a bridge composed of piers having at their top horizontal bearing surfaces, on which rest successive deck elements.
  • Bridges constructed according to the technique just indicated are very widespread, generally the deck elements are prefabricated on the ground, and put in place so that they rest by their two ends on the top of a pile. Although the inherent stability of such constructions is very good, it is preferred, especially in the case of railway bridges, or bridges built in seismic zones, to secure the deck elements with the piers, while leaving the possibility of the small movements necessary, in order to prevent movements of large amplitude which could lead to the fall of the element of the deck, for example in the event of derailment or of earthquakes.
  • stabilization rods are provided which pass obliquely on the one hand all or part of the deck element, outside the pile, and on the other hand, part of the pile, which extends horizontally in a direction parallel to that of the bridge, and which constitutes a console.
  • Such an arrangement is expensive, because it requires a widening of the top of the stack, more or less long holes in the thickness of the deck, and stabilizing tie rods of a relatively large length.
  • the object of the present invention is to provide a bridge in which the problem of stabilization is resolved in a simpler and less costly manner, while having an efficiency at least equal to that of the known device.
  • the invention provides a bridge composed of masonry piers carrying at their top essentially horizontal bearing surfaces, on which rest successive deck elements via support plates designed to allow the possibility of small relative movements, stabilizing tie rods connecting the deck elements to the stacks so as to prevent an unwanted relative movement, in particular vertical, while leaving the possibility of said small movements, this bridge having the particularity that each apron element is integral with a metal retaining plate, more or less horizontal, which rests on the said plate or plates and protrudes beyond this plate or these plates in the direction of the vertical axis of the stack, and the stabilizing tie rods are substantially vertical and connect the stack to said plate.
  • the arrangement according to the invention makes it possible to reduce both the volume of the top of the pile, and the length of the anchor rods, in particular by the fact that they no longer have to cross a more or less significant portion of the height of the deck element, but only the metal plate, which, despite its robustness, is obviously less thick.
  • the invention can be applied to the case where the deck elements are metallic constructions, but of course, it applies more particularly to the case where these elements are made of concrete.
  • the deck elements rest on the top of the pile by means of rigid support plates or of elastomeric material, intended to avoid direct contact of the concrete of the deck element with the concrete of the pile.
  • the retaining plate is anchored in the concrete of the apron and constitutes the part of the lower surface of said apron which rests on the support plate or plates, and the retaining plate comprises an extension extending from the support plate or plates towards the axis of the stack, this extension carrying the means for fixing the stabilizing tie rods.
  • the anchoring of the retaining plate in the concrete of an apron element can be carried out using vertical bars welded on said plate and penetrating into the concrete of said element, it can also be carried out using at least one vertical plate, supported on a vertical surface of the deck element, and to which are welded horizontal bars penetrating the concrete of said element.
  • the stabilizing tie rods pass through the holding plate by one end provided with a thread, and bolts are screwed onto the part of the tie rod which protrudes above the holding plate.
  • the lower end of the stabilizing tie rods can be anchored in the top of the stack, but, according to a preferred method, these tie rods pass through the top of the stack to a roughly horizontal surface facing downwards, the end lower of said tie rods is threaded and carries a nut which rests on said roughly horizontal surface. In this way, replacing a stabilizer rod is an easy thing.
  • the figures show a pile 1, made of concrete, of which only the upper part has been shown.
  • This stack comprises a barrel 2, vertical and having an interior cavity 3 closed, and a head 4, massive, which has the general shape of an inverted pyramid trunk.
  • the underside of the head 4 has a horizontal surface 5 which closes the cavity 3 of the barrel of the stack.
  • the upper surface 6 of the stack is also horizontal.
  • This plate the shape of which is given in FIG. 3, comprises a rectangular part 19, and a projection 20, directed towards the opposite deck element.
  • the part of the plate 17 furthest from the vertical axis AA of the stack rests on the neoprene plate 9.
  • the opposite part, which is in the extension 20, has two holes 21 through each of which passes a tie rod stabilization 22.
  • tie rods are vertical, and pass through the head 4 of the stack by holes 23, elongated in the direction of the bridge, their width in this direction being approximately equal to that of the expansion interval 14. It should be noted that , in the transverse direction, the width of the holes 23 is quite clearly greater than that of the tie rods 22, to also allow a certain transverse play.
  • each of the tie rods 22 are threaded and carry nuts 24, 25, which are in contact with the plate 17 on one side and with the lower surface 5 of the head on the other side, by means of support plates 26, 27 and elastic elements 28, 29. It should be noted that the stabilizing tie rods do not exert an appreciable prestressing force, which would lead to a permanent bending stress on the plate 17 and would harm the good support of the latter on the neoprene plate 9.
  • the tie rods are threaded metal bars. They can also be formed by cables provided with hooking heads at their ends, but which, unlike the usual prestressing cables, are not tensioned in normal service.
  • the lower part of the tie rods can also be fixed in a non-removable manner in the head of the pile, for example by anchoring in concrete.
  • tie rods are constantly under tension.
  • the backing plates must then be reinforced accordingly.
