Definitions

  • the present invention relates to a device for distributing studs in an apparatus intended to drive in and position studs in freshly poured concrete slabs, apparatus comprising a lower smoothing plate possibly attached to the rear part of a compactor-finisher machine and intended to rest and slide on the surface of the already compacted concrete slab, provided with a series of openings arranged in line at determined intervals, allowing the installation of studs by pressure guides capable of sliding along columns vertical to ensure the insertion of driving studs into the concrete not yet taken from the slabs.
  • a device for driving and positioning parallel studs in concrete road slabs, on either side of the joints between these slabs, comprises a horizontal beam movable vertically at above a joint and longitudinally to this joint.
  • This known device is mounted on a lower smoothing plate having a row of openings for the passage of the studs and pressing guides ensuring the insertion of the studs into the mass of concrete.
  • the pressure guides are distributed two by two opposite one another on the horizontal beam and are directed downwards. They push the studs into the concrete not yet taken from the slabs, during the descent of the horizontal beam which also carries side clamps arranged two by two on either side of the pressure guides. These pliers grip the studs and are slidably mounted vertically and freely relative to the horizontal beam, so as to rest in the lower position against the upper faces of the slabs.
  • the manual installation of the studs is an expensive operation. It lengthens the downtime of the stud driving device, since it can in fact only be carried out during the moving times of the device from one joint to another.
  • the time available to install the studs is variable. It in fact depends on the distance separating two seals and on the speed of progress of the compactor-finisher if the smoothing plate is mounted behind it as described in European patent No. 0 051 885.
  • the present invention aims to remedy the above drawbacks. It relates to a device for distributing studs in an apparatus intended to drive and position said studs in concrete slabs not yet taken, device comprising a lower smoothing plate possibly attached to the rear part of a compacting-finishing machine and intended to rest and slide on the surface of the already compacted concrete slab, provided with a series of openings arranged in line at determined intervals, allowing the positioning of the studs by pressing guides capable of sliding along the vertical guides to ensure the insertion and driving of the studs in the concrete not yet taken from the slabs.
  • This device is essentially characterized in that it comprises a mobile loading box, partitioned into a series of vertical compartments with an open bottom, each intended to receive a stack of studs.
  • the box By traversing the smoothing plate from one side to the other, the box deposits a stud in each of the notches of a drawer frame. These notches are aligned side by side and separated from each other by determined distances. The drawer frame rests sliding on the smoothing plate.
  • the invention also relates to a method for distributing and placing studs in an apparatus for driving and positioning studs in a thixotropic concrete slab as described in European patent No. 0051 885.
  • This process is essentially characterized in that one moves from one side to the other of a smoothing plate, a bottomless carriage loaded with a sufficient number of studs in order to deposit a stud in each of the notches of a drawer-frame, placed in the waiting position, set back from the openings in the smoothing plate.
  • a device according to the invention for driving in and positioning studs 1 on either side of the expansion and withdrawal joints 2 between concrete slabs 3, comprises a lower smoothing plate 4.
  • the smoothing plate is hooked to the rear part 5 of a compacting-finishing machine for continuously casting concrete slabs.
  • the smoothing plate 4 is intended to rest and slide on the surface of the concrete slabs 3 already compacted.
  • the smoothing plate 4 is provided with a series of openings 6 arranged in line at intervals fixed by the specifications. These openings 6 allow the passage of the studs 1 and the pressure guides 7 which ensure the insertion of the studs 1 into the fresh concrete not yet taken from the slabs 3.
  • a device for automatically distributing studs capable of supplying the aforementioned apparatus, comprises a mobile loading box 8 with an open bottom partitioned into a series of vertical compartments 9. These compartments 9 are separated by vertical partitions 10 and are intended to each receive a stack of studs 1.
  • This box 8 rests by the wheels 11 on a drawer frame 12 which in turn rests on the smoothing plate 4 so as to be able to slide on the latter while being actuated by the jack 16.
  • the box 8 moves from one side to the other of the smoothing plate under the drive of the cables 13 and the winches 14.
  • the drawer frame 12 has a series of notches 15, the arrangement and spacing of which correspond exactly to the row of openings 6 provided for the passage of the studs 1 through the smoothing plate 4.
  • the series of notches 15 in the drawer frame 12 is set back with respect to the series of openings 6 in the smoothing plate 4.
  • the notches in the drawer frame 12 are in the form of recesses rectangular whose bottom is materialized by the smoothing plate 4.
  • the depth of these blind notches 15 corresponds exactly to the diameter of the studs 1.
  • the movable casing 8 By traversing from one side to the other the smoothing plate 4, transversely with respect to the direction of advance of the compacting-finishing machine, the movable casing 8 feeds studs 1 each of the blind notches 15 of the drawer frame 12.
  • the drawer frame 12 is considered to be loaded and is kept in the waiting position until the driving device is brought by the plate. trowel 4 above the joint 2.
  • the studs 1 are retained in place by fins 19 secured to the smoothing plate 4.
  • the studs 1 are pressed in when the horizontal beam 17 is just above the joint 2.
  • the horizontal beam 17 is suspended by the insulators 27 to a cross member 17 ', itself suspended by stirrups 20 and jacks 21 from a traveling crane 22.
  • the smoothing plate 4 is thus secured to a traveling crane 22 which rests by the wheels 23 on a support 5 forming part of the compactor-finisher machine not shown.
  • the vibration of the presser guides is obtained by vibrators 24 mounted on the beam 17.
  • the vertical guiding of the crosspiece 17 ' is carried out by four columns 28 provided with oblong holes 25.
  • the smoothing plate 4 is suspended from the carriage 22. Thanks to the freedom of movement of the columns provided by the oblong holes 25, the smoothing plate 4 is constantly supported on the surface of the concrete slab 3.
  • the driving of the studs 1 is controlled by the jacks. It takes place when the smoothing plate 4 is immobilized. The immobilization of the smoothing plate 4 does not, however, interrupt the continuous progression of the compactor-finisher machine, thanks to the horizontal displacement cylinders 26 which it suffices to release during the time interval necessary for the fitting of the studs. 1.
  • dampers 27 are provided.
