Definitions

  • the invention relates to steel-concrete composite structures comprising a trellis of metal tubes diagonally arranged between two concrete slabs or beams, in particular for producing a bridge deck, the roof of a building or an area, pontoon or platform.
  • connection device has been described in the publication FR 2,723,424 which comprises at each end of a trellis tube a metal plate welded to the end of the tube perpendicular to the axis of the tube, said plate being in abutment with the beam or slab and having a plurality of holes with which cooperate fastening means by screwing the plate to bars embedded in the concrete of the beam or slab.
  • An object of the present invention is to provide embodiments of such a device, advantageous in terms of their ease of maintenance and particularly effective.
  • the device is completed by removable cables which pass inside the tube, which pass through the plates located at both ends of the tube and the beams or slabs and which are put in tension as prestressing cables.
  • These cables significantly increase the resistance of the system vis-à-vis the tensile forces without having to substantially increase the dimensions of the device.
  • FIG. 1 shows a straight cylindrical metal tube (1) to which is welded peripherally (s welds), at each end, a metal plate (2) which has in plan the polygonal shape shown in FIG. 2 and which has holes (3 ), for example four holes, located outside the tube and evenly distributed around the axis (4) of the tube.
  • the tube with its two plates is supported on two parallel faces (5) of two concrete beams (P) partially visible in Figure 1: the tube is perpendicular to these faces (4) but in reality it is oblique to the planes of the beams, as illustrated for the example in Figure 6.
  • a seal is interposed between the plate and the concrete surface.
  • the device for connecting a tube to a beam is constituted, at each end of the tube, by a plurality of bars (6) which have been embedded in the concrete of the beam during the casting thereof and which have been attached by any suitable means, fittings (7) which are accessible in housing (8) formed in the concrete.
  • These connectors have a threaded bore in which is screwed a rod (9) which passes through a hole (3) of the plate and a nut (10) is screwed onto the rod until it comes into pressure on the plate, possibly with interposition of a washer (11).
  • a removable cap (12) is provided to protect the bolt.
  • connection between a tube and a beam or slab is completed by removable cables which pass inside the tube, which pass through the plates and the beams and which are stretched in a manner known per se as prestressing.
  • the plates (2) in addition to the holes (3) provided around the grip of the tube for fixing the plates to the bars embedded in the concrete, present inside the tube holes (3 ') for the passage of the cables, for example two diagonally opposite holes (Figure 5).
  • the holes (3) located outside the tube for fastening the tube to the bars (6) anchored in the concrete are regularly distributed around the tube either individually ( Figure 2) or in pairs ( Figure 5) and the holes (3 ') located inside the tube for the passage of the prestressing cables are regularly distributed between the holes (3) or between the pairs of holes (3) ( Figure 5).
  • Each prestressing cable passes into a sheath (13) which comprises a section of sheath (13a) placed inside the tube and sheath sections (13b) placed in place in the beams and nested at their ends in hollow metal parts (14) taken in the concrete beams.
  • the cables themselves pass through these parts and are removably retained by conventional means, for example jaws (15) accessible outside the beams.
  • FIG. 7 shows the end of a duct section (13b) fitted into a hollow metal piece (14), and the strands of a cable (16) are seen in this figure. coming out of the room and stuck in a bit (15).
  • the bars and their removable connections ensure resistance to the ultimate limit states and also removable cables ensure non-decompression under stress of fatigue.
