Definitions

  • the present invention relates to elongated elements, generally prismatic or cylindrical made of prestressed concrete and, optionally, at the cost of a simple arrangement, assembled end to end.
  • a known palliative of these drawbacks consists in providing the ends of such elements, with steel plates, traversed, during manufacture, by the tensioned reinforcements and comprising, towards the interior of the element, sections of ordinary welded reinforcements. on the internal face of these plates.
  • These complementary reinforcements reinforce the non-prestressed ends of the element while the plates can facilitate an end-to-end assembly of the elements.
  • the invention provides an improved solution to this problem.
  • the two ends of the sections of adherent reinforcements corresponding to the same elongated element are made integral with two chassis, the contour of which corresponds to the section of this element, a chassis which, after tensioning the reinforcements through of these, then concreting of the element, are permanently incorporated into the ends of this element, said frames having the form of housings constituting the ends of the finished element; and the fixings of the frames are internal to these boxes; thus the concrete inside the housings is both compressed by the tension of the reinforcements and shrunk by the periphery of these housings.
  • these frames cut to exact length, are provided at their ends (by forging, welding, crimping, etc.) with a robust button and the frame has notches of width just equal to the diameter of the reinforcements which, consequently, retain the buttons.
  • the chassis externally comprise waiting assembly members, for example ears capable of receiving fixing means such as flanges , bolts, hooks etc.
  • the end boxes have flat-head mushroom-shaped extensions which applied one against the other can be assembled by a necklace.
  • the re-entrant edges of these mushroom caps are inclined so that, by wedge effect, the tightening of the collar strongly applies the flat heads against one another.
  • Fig. 1 is a middle section of an element end also showing the connection of two elements.
  • Fig. 2 is the section along II-II of FIG. l.
  • Fig. 3 partially shows a stake comprising two assembled elements.
  • Fig. 4 shows diagrammatically at one of its ends a device for manufacturing elements according to the invention.
  • the element end A is prestressed by the adherent reinforcements 1 which are provided at their ends with crimped heads 2.
  • a housing 3 provided with a re-entrant edge 3a in which are provided notches 4 of width equal to the diameter of the frames 1, so that they retain the heads 2 after the frames have been placed; ribs 3b, molded with the housing and framing each of the notches, strengthen the resistance of the edge 3a called to withstand the tension of the frames.
  • the drawing shows an embodiment of the housing 3 allowing the end-to-end assembly of two elements by means which do not extend beyond the section of the assembled elements as is the case for example for piles formed of successive elements. Otherwise the housing 3 can be provided at its periphery with ears or flanges which, as will be shown with reference to FIG. 4, are used to tension the reinforcements.
  • the housing is extended by a head 3c in the general shape of a mushroom, the external face of which is flat, so that it can be applied tightly against the analogous face of an element such as B intended to be assembled with the element A; the center of the head has a third recess for the establishment of a pin 4 which centers the heads relative to each other.
  • the internal edge 3f of the head is oblique with respect to on the 3d flat face and, in addition, the 3d head has, in plan view (fig. 2), an octagonal shape close to the square.
  • two adjoining heads can be assembled by a frame-shaped collar 7 formed by four parts 5 assembled by bolts 6 engaged in the ears 5a which terminate the parts of the frames 7.
  • Each of the parts 5 has two oblique faces 5b and 5c in look which encloses the faces 3f of the joined heads; moreover, the obtuse angle shape of the parts 5, adapted to the plan shape of the angles of the head, provides a double clamping effect on the heads 3c by radial and longitudinal sliding of the clamping faces 5b and 5c against the corresponding faces 3f, when tightening the bolts 6.
  • the concrete of each element, outside the housing, is prestressed by the reinforcements 1; that which is in the housing is hooped by this housing (and also partially prestressed by the elastic deformation of the housing during the tensioning of the reinforcements); the flat 3d faces of the heads ensure the transmission from one element to another, compressive forces; the frame 7 supports the tensile forces between elements and also due to its shape the torsional forces; finally the pin 4 resists possible shearing forces between elements.
  • the embodiment shown in FIGS. 1 and 2 lends itself particularly to the production of very long piles formed of elements such as A and B, their assembly comprising no lateral projection liable to hinder the driving of the pile.
  • the invention also makes it possible to produce, from elements prestressed by adherent reinforcements, continuous beams; in this case the housing can be terminated directly by a flat face provided with a rim similar to that of the head 3c because in this case the overflow of the assembly means can be without disadvantage.
  • Such flanges allow, as shown in FIG. 4, the tensioning of the reinforcements 1 during the manufacture of an element.
  • the housing 3 can be immobilized by passive means. After tensioning the reinforcements, the concrete is poured into the mold until hardening which allows the release of the tensioning means.
  • the trimmer 8 can be associated with a plurality of molds joined sideways, which allows the simultaneous manufacture of a large number of elements.
  • the invention applies as much to separate elements (beams, piles, railway sleepers) comprising adherent reinforcement as to complex structures formed of elements of this kind, assembled.
