Definitions

  • the invention relates to a new bridge structure with prefabricated segments and with external overall prestressing by cables, this means that the cables pass outside the concrete of the structure, and it also relates to a new segment to constitute such a bridge. .
  • the invention aims to provide a new bridge structure facilitating the production of deflectors and anchors for prestressing cables.
  • each segment comprises two tables, respectively upper and lower, braced by pairs of longitudinal sails oblique to a vertical plane which form dihedrons, and by the fact that some of the dihedrons are closed by a transverse eardrum, the eardrums ensuring the desired deviations of the prestressing cables, as well as the anchors of these cables.
  • the eardrums are located at the ends of the dihedrons.
  • FIG. 1 The current bridge span shown on. Figure 1 comprises, between the two supports 1, 2, a series of segments, that is to say of prefabricated cross sections, V 1 to Va.
  • Each segment V comprises an upper table H and a lower table B braced by longitudinal oblique sails.
  • certain segments V 3 , V 4 , Va and V 7 have transverse eardrums T between the tables.
  • the span is prestressed by cables C which undergo deviations only at the places of the eardrums, which are precisely provided for this purpose.
  • cables C which undergo deviations only at the places of the eardrums, which are precisely provided for this purpose.
  • the cables are also deflected in concrete blocks 3, 4 in a manner known per se.
  • Each segment ( Figures 2, 10) comprises an upper table H and a lower table B braced by concrete sails R oblique to a vertical and longitudinal plane which form a series of isosceles dihedrons whose edges are located below in the lower table. It has been assumed, for the example, that the segment comprises 6 R sails forming 3 dihedrons. In this example, the dihedrons are contiguous step by step. This provision is not compulsory. Alternatively, the ⁇ dihedrons can be spaced.
  • FIG. 18 shows three embodiments in which the dihedrons are contiguous (FIG. 18A) or non-contiguous (FIGS. 18B and 18C).
  • the number of dihedrons is chosen according to the width of the bridge and the desired resistance, generally 2 to 4 dihedrons per segment are sufficient.
  • the segments have respectively 4 dihedral ⁇ 1- ⁇ 4 (FIG. 18A), 3 dihedral ⁇ 1 - ⁇ 3 (FIG. 18B) and 2 dihedral ⁇ 1- ⁇ 2 (FIG. 18C).
  • segments include one or more transverse or vertical eardrums.
  • the process is completed by the operations consisting in prefabricating triangular plates T having the dimensions of the eardrums, these plates comprising projecting lateral frames, and placing each triangular plate T in front (that is to say at one end) of the dihedral which the eardrum must close, crossing the lateral reinforcements c of the triangular plate with the reinforcements b of the two rectangular plates which constitute the dihedral and the reinforcements d sink tables.
  • Formwork and pouring are carried out as in the first case.
  • the triangular tympanum plate is located on the side of the counter-mold formed by the segment previously manufactured and from which the new segment is produced.
  • the eardrums which are used to deflect the prestressing cables have cable passages and these passages are formed at any desired time, during the manufacture of the triangular plate or later, depending on the organization of the site.
  • Figures 11 to 17 are similar to Figures 3 to 9, but relate to the manufacture of a segment comprising eardrums. We have assumed that this is the segment V 3 which is poured using the segment V 2 as a counter-mold ( Figures 11, 14, 15, 16).
  • the prestressing cables C are located on the cylinder with a horizontal axis, the directrix of which is parallel to the axis of the structure.
  • each prestressing cable is preferably placed in a vertical plane parallel to the axis of the structure.
  • the eardrums are located where the prestressing cables should be deflected or fixed.
