Definitions

  • My invention relates to a slip-form paver. It has to do, more particularly, with a paver of this general type which is adapted to move over road forming material deposited on the surface to be covered in front of the paver and to form therefrom a monolith or slab of desired thickness and surface contour. More specifically, it is designed for acting on concrete material.
  • the ditiiculty of these rough edges occurring on the pavement slab is overcome by having vibrating means carried by the side forms which will vibrate them as they are carried along by the machine.
  • the vibrating means will produce a percussive or hammerlike vibration on each form which will be directed inwardly towards the edge of the concrete in a direction preferably substantially at right angles to the form and the associated edge of the concrete.
  • This hammering action will cause compaction of the edge of the concrete to cause it to more quickly set sufficiently so that the side form can slip aiong without adhering to the concrete and producing a rough edge thereon.
  • the hammerlike vibration therefore, not only aids in separating the form from the edge of the concrete but compacts the material adjacent it to produce an edge which is not only more desirable in appearance but is more rugged to resist deterioration under load and adverse weather conditions.
  • FIGURE 1 is a plan view of a paver embodying my invention.
  • FIGURE 2 is an enlarged, transverse, sectional view through a form carried at one side of the payer and illustrating how it forms the edge of the concrete slab.
  • FIGURE 3 is a similar view but illustrating the action of the vibrating means carried by the form on the associated edge of the concrete slab.
  • a slip-form paver which includes a pair of parallel, laterally spaced forms it which are of considerable length and extend longitudinally of the paver. These forms are connected to move along the surface to be covered by suitable traction means such as the crawler tracks 11 which are disposed outside the forms It and which may be driven by a suitable driving unit 12.
  • the machine preferably includes a forward, transversely extending strike-off member 13 which will strike-01f the 3,015,269 Patented Jan. 2, 1962 concrete material dumped in front thereof between the forward extensions of the for-ms I0. This strike-off will roughly strike-elf the pile of concrete material to the desired level and contour.
  • the machine also includes a following surfacing member of screed 14 which will produce the final surface on the struck-off concrete material.
  • a following surfacing member of screed 14 which will produce the final surface on the struck-off concrete material.
  • any suitable surface finishing member may be employed, such as a surfacing belt or the like.
  • the rearward extensions of the forms 10 are relatively short, it will be understood that in actual practice, in a machine of this type, the forms 10 will extend rearwardly behind the final surfacing member 14 a long distance which will be suflicient to permit the setting of the edges of the con crete slab before the forms leave such edges unsupported.
  • This means comprises vibrating units 15 which are mounted on the forms. These vibrating units may be of various well-known types but are preferably of the electromagnetic type. As indicated best in FIGURES 2 and 3, each unit 15 is bolted or otherwise rigidly fastened at 16 to the outer vertical surface of the vertical wall of the form. Each unit is so disposed on the form that, as indicated by the arrow in FIGURE 3, a vibratory force will be exerted inwardly and outwardly substantially at right angles to the vertical wall of the form and to the associated edge of the concrete slab S. The units 15 preferably apply hammerlike blows to the forms.
  • each form carry one of the units directly behind the strike-off 13 and directly behind the surfacing member 14.
  • the vibratory means will function to compact the edges of the concrete and loosen the slip form from the concrete. it is especially important to have the vibrating units behind the final material leveling or surfacing member.
  • this paver will move into engagement with the concrete material dumped on the surface and will form therefrom a slab of concrete, the slip forms carried by the pa er forming the edges of the slab.
  • the forms will progressively slip along the slab edges and by the time the forms leave the edges, they will be set sufficiently to retain their shape and this setting will be accelerated by the vibrating action on the forms. Furthermore, the vibrating action will prevent adherence of the concrete to the slip forms and, consequently, the formation of rough edges on the concrete.
  • the method of forming a pavement of concrete or similar material which comprises providing concrete material along the surface to be covered, moving side forms along the surface together with a leveling member which will level the material against the side forms, and vibrating the side forms with hammerlike blows transversely of the forms as they are moved along to compact the edges of the material and to prevent sticking of the side forms to the material.
  • a slip-form paver comprising longitudinally extending, laterally spaced forms adapted to form the edges of material and having vertical edge-forming walls, a leveling member carried by the forms for leveling the material therebetween against the Walls of the forms, vibrating means carried by the forms, said vibrating means comprising a vibrating unit carried by each form behind the leveling member, said vibrating units being carried outside the associated forms and exerting hammerlike blows on the forms substantially at right angles to the vertical Walls of the forms.
