Definitions

  • the invention is based on a method for laying mesh fabric for reinforcing bitumen-bound ceilings from streets or the like, in which after the formation of a planum of a bituminous base layer, for example, a 200 m long web of mesh fabric is laid on the planum, the beginning of which is based on a fabric sleeve, which is wound transversely to the production device, is fixed against the formation and the fabric sheet is unwound from the support sleeve while moving the support sleeve in the production direction, and the mixed material is applied to the laid mesh fabric to form the ceiling by means of a paver, the one equipped with a trolley
  • the paver in the production direction behind the carriage has a screed that distributes and releases the mix over the production width and push rollers in front of the carriage for the trucks that bring the mix to the paver.
  • the entire length of the fabric of the lattice fabric is laid by unwinding from the support sleeve and rolling it onto the surface of a bituminous base layer. Thereafter, the fabric web is fixed at the beginning and optionally at its side edges, for example by driving in wide-headed nails, against the formation. Then the laid mesh fabric is run over by the paver as well as by the truck transporting the mix for the manufacture of the blanket to the paver. In this case, stresses on the laid mesh fabric occur that are so large that, despite the fixation of the mesh fabric along its side edges, considerable distortions and distortions of the mesh fabric occur. Also, if the truck transporting the mix too violently starts or brakes, the mesh fabric is not only shifted and discarded, but sometimes also torn.
  • nonwoven webs have also been proposed for reinforcing road surfaces. It is also conceivable that net-like structures can be used instead of lattice fabrics.
  • the present invention has for its object to avoid these disadvantages of the known method for laying in particular fabrics or other textile fabrics for reinforcing bitumen-bound road surfaces or the like and to provide a method and a device in which the laid fabric, fleece or the like no longer is exposed to the stresses described.
  • this object is achieved according to the invention in that the textile web is unwound during the production of the cover layer from the support sleeve, which is located between the push rollers and the screed of the paver and is moved together with the paver in the direction of production, whereby the fabric web is laid under pre-tension while exerting a tensile force acting in the production direction.
  • a suitable device for performing the method is specified in claim 3.
  • the support sleeve with the wound-up lattice fabric can be arranged between the screed and the undercarriage in a paver whose chassis is a chain undercarriage, or else between the undercarriage and the push rollers. In the latter case, the installed grid fabric is run over by the paver's crawler chassis, but these strains are considerably lower than the strains caused by the truck moving with mixed material to the paver and the empty truck moving away from the paver.
  • the ends of the support sleeve emerging from the fabric roll or bearing pins which can be inserted into the support sleeve can be received from open-top bearings.
  • the laying device In order to be able to align the fabric sheet, particularly when two fabric sheets overlap one another, with respect to the longitudinal axis of the paver, the laying device should be wider than the widest fabric sheet to be laid, so that the fabric roll to be picked up by the laying device can be aligned within this device with respect to the longitudinal axis of the paver.
  • the laying device it is also possible to arrange the laying device on the paver, which can be moved and locked transversely.
  • the laying device is provided with a brake roller which is adjustable in its braking action.
  • This brake roller can be provided with teeth or spikes that engage in the mesh fabric.
  • the brake roller can also work together with a counter roller, so that the fabric web is passed between these two rollers in a clamping manner.
  • a signaling device which responds to labels which are attached in the end region of each mesh fabric. These marks can be attached 10 m before the end of the fabric web and made of an electrically conductive or a magnetic material exist so that the alarm is triggered by an electrical contact caused thereby or by a magnetically responsive sensor.
  • the laying device can also be equipped with measuring wheels which engage in the web of fabric to be removed, which indicate the length of the web of web laid in each case and thus also report in good time when a new fabric roll must be used.
  • the laying device So that a crease-free laying of the mesh fabric is also possible in curves, it is further proposed to equip the laying device with a cutting device which cuts the fabric web depending on the curvature of the road surface to be reinforced from the left or also from the right side.
  • FIG. 1 and 2 show the laying of a fabric web 2 wound to form a fabric roll 3 for reinforcing a bitumen-bound ceiling 4 of a road, in which, after the formation of a planum 1 of a bituminous base layer, a 200 to 300 m long web of a mesh fabric by means of a ceiling paver 5 the level 1 is relocated.
  • the paver 5 is equipped with a carriage 6 with which it can be moved in the production direction on the subgrade 1 of the base layer. Behind the undercarriage 6 is a screed 7 which distributes and releases the mix over the production width.
  • the mix is brought by truck 10 to the paver and tipped there into a receptacle 9.
  • the truck 10 is pushed in the production direction by push rollers 8 arranged on the front of the paver 5 and pressing against the rear vehicle wheels.
  • the paver 5 is provided with a laying device 11 which is provided with a bearing for the fabric roll 3 or its support sleeve 12, in which the support sleeve 12 is rotatable about an axis parallel to the longitudinal axis of the screed 7 is.
  • the laying device 11 is provided with at least one pressure roller 14 pressing the fabric web 2 onto the level 1 of the bituminous base layer.
  • This pressure roller 14 is either made of an elastic material, so that the fabric web 2 can be reliably pressed onto an arched or kinked flat surface 1, or the pressure roller is composed of several rollers which are arranged next to one another and can be pressed independently of one another.
  • the laying device 11 is further provided with a tensile force exerted on the unwound web 2 brake roller 15, the braking force is adjustable.
  • the brake roller 15 is provided with spikes or teeth which engage in the mesh fabric 2 to be installed.
  • This brake roller 15 can also be used as a measuring wheel of a length measuring device, which indicates the length of the fabric web that has been laid.
  • the braking force of this brake roller 15 is adjustable so that an adjustable tensile force can be given up between the brake roller 15 and the fabric already under the ceiling 4, which tensions the mesh fabric in the direction of manufacture. So that the tissue pressed on by the pressure roller 14 is as wide as possible, a spreading device 17 is also arranged on the laying device, which stretches the fabric web 2 transversely to the production direction.
  • This spreading device consists, in particular, of inclined rollers arranged in the edge regions, which are provided with spikes, needles, bristles or grooves for taking and spreading the fabric.
  • the spreader rolls can also be made of hard rubber or plastic and have grooves running in a helical shape.
  • the spreading device 17 is arranged directly in front of the brake roller 15 provided with spikes or teeth.
  • the laying device in the paver according to FIGS. 3 and 4 has a chassis 20 which is held transversely to the longitudinal axis of the paver 5 and can be locked on the paver.
  • This chassis 20 can be drawer-like on guide rails 24 of the paver. In this way, the fabric web to be laid can be aligned transversely to the production direction.
  • a hinged protective wall 26 is arranged on the chassis 20 of the laying device 11 and can be opened to insert a fabric roll 3.
  • the laying device 11 is connected via the strips 24 to the support arms 22, which for lifting ben the screed 7 can be raised by means of a lifting cylinder 21.
  • the laying device 11 can also be arranged between the push rollers 8 and the undercarriage 6 of the paver 5.
  • the installed grid fabric is run over by the undercarriage 6 of the paver 5, but there are fewer structural problems with the arrangement of the laying device 11 and the refilling of the laying device with a fabric roll 3 is simplified.
  • the parts of the laying device are arranged within a frame 30 which is articulated on the front of the paver 5 so as to be pivotable about an axis transverse to the production direction.
  • This frame 30 is supported by the pressure roller 14 against the subgrade 1.
  • the push rollers 8 are arranged.
  • a bridging conveyor chute 31 is provided, which bridges the increased distance between the approaching trucks and the front of the paver 5.
  • the conveyor chute 31 can be height-adjustable by means of a hydraulic cylinder 32.
  • the brake roller 15 works together with a counter roller 16. These two rollers lie against each other with a prestress. At least one of the two rollers is braked.
  • the laying device 11 is also equipped with a cutting device 18, which is composed of a cutting table 19 and a cutting knife 33 which can be moved transversely to the fabric web 2.
  • a cutting device 18 which is composed of a cutting table 19 and a cutting knife 33 which can be moved transversely to the fabric web 2.
  • the laying device 11 according to FIG. 6 has two parallel shafts 34 and 35 on which the fabric roll 3 is mounted such that it can be unrolled.
  • the paver can also be designed as a so-called repaver or reformer, provided that the laying device is arranged in front of the screed.
  • the fabric web should be guided via lateral guides and driven by spiked rollers, spreader rollers or the like so that the tissue remains in its guide after the tissue has been cut.
  • transverse stiffener is attached, which is formed by a sheet or plastic strip or a tongue, which makes it possible to pass the wide fabric web over the various rollers without difficulty. This transverse stiffening also serves to fix the beginning of the fabric sheet in relation to the level 1.
