Definitions

  • the present invention relates to a device for driving and positioning studs in concrete slabs during the construction of a road.
  • the studs are placed parallel to each other on either side of the joints separating the slabs and perpendicular to these joints.
  • studs designates a stud proper or a similar bar allowing the withdrawal or the expansion of the concrete from the slabs which it connects and constituting a load transfer element on either side of the joint between these slabs.
  • German device DE-A 2406925 discloses a device mounted on a compactor-finisher machine, this device being intended to drive and place steel studs in the freshly poured concrete of a concrete road slab.
  • the device comprises a horizontal beam which comprises several stud stores and pressure guides distributed two by two opposite one another and directed downwards, intended to push the studs out of support clamps holding said studs in position waiting and driving these studs down to the lower position in the concrete not yet taken from the slabs, these clamps being able to slide vertically and transversely with respect to the horizontal beam.
  • the device is mounted on a carriage suspended from rails and designed to move along the aforementioned machine.
  • the subject of the present invention is a device for placing studs at the joints of road concrete slabs which overcomes the drawbacks of known techniques.
  • the device according to the invention is of the type according to DE-A-2406925, it makes it possible to drive and position by vibration parallel to each other, studs in concrete slabs during the construction of roads, horizontally, on both sides and the other of the joints separating these slabs and perpendicular to these joints, comprising a horizontal beam which comprises at least one store of studs, pressure guides, vibrators and holding members intended to grip the studs and which is mounted on a frame independent so that it can be moved vertically by displacement means over a joint, in order to drive these studs down to the lower position in the concrete not yet taken from the slabs, the studs being separated from the holding members under the action of vibrators on the beam and pressure guides on said studs.
  • the device of the above type comprises a lower smoothing plate intended to rest and slide on the surface of the already compacted concrete slab, this lower plate comprising openings for the passage of the studs and pressure guides fixed to the above-mentioned horizontal beam sliding downward along vertical guides to ensure the insertion of the studs into the concrete not yet taken from the slabs while the holding members bear on the aforementioned lower plate so as to obstruct said orifices.
  • the bottom plate or smoothing plate of the device according to the invention prevents alterations to the surface of the slabs, due to vibrations when the studs are driven in.
  • the device according to the invention can be produced as a dowel-smoothing device independent of the compactor-finisher machine. It is then hung on a compacting-finishing machine with sliding formwork which distributes, compacts and finishes a concrete slab in continuous advance, by drive means allowing a discontinuous movement of said device relative to said machine, which avoids the stop of the latter during the stud positioning operation.
  • the device according to the invention can also be connected directly to the chassis of a compacting-finishing machine. This implies the interruption of the continuous progression of the latter, for the duration of the positioning of the studs, but unlike the known devices, this stopping does not constitute a drawback, since the forces exerted for the driving in of the studs are not transmitted to the chassis of the compacting-finishing machine, but to the bottom plate or smoothing plate of the device.
  • the device can be suspended from a horizontal beam integral with the chassis of said compacting-finishing machine by articulated or sliding means, capable of carrying part of the weight of said device by said chassis. the machine.
  • These means may in particular include a compensation mechanism, intended carry said device with a constant, adjustable weight, by the chassis of the machine.
  • the above-mentioned articulated means consist of pairs of rods each forming a parallelogram articulated with the horizontal beam of the chassis of the machine and with the lower smoothing plate of the device.
  • the compensation mechanism is advantageously constituted by rods articulated on the rods and suspended from springs. These springs can bear on a guide carried by the horizontal beam of the chassis of the compactor-finishing machine. They each carry a rod by a nut screwed to the threaded end of each rod.
  • the means for vertical displacement of the horizontal beam advantageously consist of hydraulic cylinders, suspended from supports fixed to said bottom plate of the device.
  • the stud holding members can advantageously be constituted by stud holding clamps and can be slidably arranged with the horizontal beam, on either side of the pressure guides, as in the devices known described above.
  • the device shown is used to drive in and position studs 1 in concrete slabs 2 for roads.
  • the studs 1 extend on either side of the expansion and withdrawal joints between the slabs 2.
  • the studs 1 are mutually parallel and perpendicular to the joints of the slabs 2.
  • the device shown is attached to the rear part of a compacting-finishing machine for continuously casting concrete slabs 2.
  • the device for driving and positioning the studs 1 in the concrete constituting the slabs 2 essentially comprises a smoothing plate 4 suspended from the post beams 3 forming horizontal support arms of the chassis 9 of the compactor-finisher machine and resting on the surface of the slab in concrete 2 placed by this machine, as well as a horizontal beam 5 suspended by means of vertical displacement cylinders 6, to supports 7 fixed on the smoothing plate 4.
  • the smoothing plate is attached to the chassis 9 of the compacting-finishing machine by means of jacks 8.
  • the device for driving in and positioning the studs thus placed at the rear of the compactor-finisher machine, is driven by the latter in a direction perpendicular to the joints between the slabs 2, and can be moved in a translational movement relative to to the machine by actuating the jacks 8 attached to the chassis 9 of the compactor-finisher machine and articulated at 10 to the smoothing plate 4 of the device.
  • the device as a whole is suspended from the beam or support arms 3 of the chassis 9 of the compactor-finisher machine, preferably by means of articulated means 11 capable of causing the device to be carried by the posterior beams or support arms. 3 of chassis 9 of the compacting-finishing machine with an essentially constant and adjustable force.
  • the articulated means 11 are constituted by pairs of rods 12 each forming with the horizontal beam or support arms 3 of the chassis 9 of the machine and with the smoothing plate 4 an articulated parallelogram intended to take up part of the driving forces of the studs 1 in the concrete slab 2 in order to avoid an undesirable inclination of the smoothing plate 4, which inclination would cause unacceptable unevennesses in the surface of the concrete slabs 2.
  • the articulated parallelograms are articulated with compensation mechanisms 13 constituted by rods 14 which can be suspended from springs 16, these springs 16 bearing on a guide 15 carried by the horizontal beam or arm 3 of the chassis 9 of the compactor-finisher machine.
  • the stress of the springs 16 is adjustable by modifying the position of a nut 17 screwed to the threaded end of each rod 14. It is thus possible to adjust the load of the device on each of the beams or arms 3 of the compactor-finisher machine.
  • the arrangement described above allows the driving in and positioning of the studs without interrupting the continuous progression of the compactor-finisher machine. It is sufficient, during each aforementioned operation, to release the horizontal displacement cylinders 8 to immobilize the smoothing plate 4 on the concrete slab 2 for the duration of installation of the studs 1.
  • the device When the insertion and insertion of the studs 1 are completed, the device is returned to the compactor-finisher machine by actuation of the jacks 8.
  • the insertion and the installation of the studs are carried out by displacement of the horizontal beam 5 of the device.
  • This horizontal beam 5 extends parallel to the joint separating the slabs 2, and is movable vertically above the joints.
  • the horizontal beam 5 is raised and lowered by the vertical displacement cylinders 6.
  • the horizontal beam 5 carries lateral clamps 18 arranged two by two along its longitudinal edges and placed one against the other.
  • Each clamp 18 is in fact made up of two arms articulated around an upper pivot 19 and constantly urged towards each other by a return spring 20.
  • the arms of each clamp 18 have in their lower part recesses 24 of which the widths correspond to the diameter of the studs 1.
  • Each clamp 18 is guided by an upper lateral collar 21 and by a lower lateral collar 22 fixed to the horizontal beam 5.
  • the upper pivot 19 of each clamp 18 projects on either side of the arms of this clamp and serves as a stop for the upper lateral collar 21.
  • each clamp 18 allows the horizontal beam 5 to move vertically when the studs 1 are pushed in (FIG. 3).
  • Presser guides 23, integral with the horizontal beam 5 are distributed regularly in pairs between the pairs of lateral clamps 18 and are arranged one opposite the other. These pressure guides 23 each consist of a bar, the lower end of which has a notch 27 open at the bottom, corresponding to the diameter of the studs 1. They are fixed laterally to the horizontal beam 5 and directed downwards. When lowering the horizontal beam 5, the pressure guides 23, which are also driven downward, push the studs 1 downwards and force the arms of the holding clamps 18 to open against the springs 20, so as to release these studs 1 which are then driven into the concrete by presser guides 23 through openings 26 formed in the smoothing plate 4 (FIG. 4).
  • the horizontal beam 5 is further equipped with one or more vibrators 25 mounted on its upper face and capable of transmitting appropriate vibrations to it.
  • the device described above Before driving in and positioning the studs 1 in the not yet set and practically plastic concrete of the slabs 2, the device described above is located above these slabs 2, resting on their surface by its smoothing plate 4. In the upper position ( Figure 3) of the horizontal beam 5, the studs 1 are gripped by the side clamps 18. For this purpose, the ends of the studs 1 are engaged in the recesses 24 of the clamps 18 and rest by their weight against the bottoms of these recesses 24, formed in the ends of the arms of these clamps 18.
  • the horizontal beam 5 is lowered under the action of the vertical displacement cylinders 6.
  • the lower ends of the clamps 18 meet the face upper of the smoothing plate 4.
  • the clamps 18 remain in place, but this horizontal beam 5 with the pressure guides 23, continues its descent by sliding along the clamps 18 immobilized.
  • the pressure guides 23 come into contact with the studs 1 and exert on them forces directed downwards.
  • the pressure guides 23 then push the stud 1 through the openings 26 formed in the smoothing plate 4, in the concrete of the slabs 2, to their final lower position.
  • the device described above therefore allows, without specialized labor and without difficulty of execution, to drive in and correctly and directly place a large number of studs, without seriously disturbing the upper surface of the concrete slabs. during the installation of the studs, this surface being moreover again equalized by the smoothing plate when the latter is withdrawn by the jacks 8.
