  • the screeds are direct stored on the main screed. This storage of the screed on the main screed has not proven to be sufficiently stable Avoiding tilting of the screeds compared to the Main screed proven.
  • EP-A-0 367 893 describes a screed for pavers known, the working width will double leaves; the storage of the sliding screeds on the main screed but takes place via separate (tiered) management bodies and not with intermediate slide. This leads to double Working width of extended screeds to reduce stability.
  • the invention has for its object to a screed create an increase in the working width by the full Width of each shifting screed enables and stable Storage of the screeds on the main screed ensured.
  • the intermediate slide projecting governing bodies for Inner plates of the sliding screed is achieved in that to the The end of the main screed driven intermediate carriage Intermediate sled assigned guide members on the outer The ends of the main screed protrude.
  • the executive bodies provide in this way quasi “extension arms" for the inner panels of the Moving planks that allow the moving planks completely out of the area of the main screed, and so far that there is no overlap between mutually pointing End areas of the main screed and the respective shifting screed there is more.
  • the management bodies are at least opposite to the ends the main screed facing end plates of the intermediate slide in front.
  • the management bodies end by the according to the invention similar to a support arm compared to the outer end plate of the respective intermediate slide protruding management bodies an extension of the guide elements of the intermediate slide brought about, with which the sliding screed to the outer end plates of the main screed are extendable past.
  • the management bodies connected to the intermediate slide at opposite ends.
  • the full length of their governing body stands for moving the screed.
  • the management bodies are attached to the Intermediate sledges indirectly by means of supporting elements with inner and outer end plates of the intermediate slide firmly connected are. End flaps at the ends of the support members are used for Attachment of the ends of the guide elements. Through this type of Attachment it is possible to twist the guide elements to attach to the intermediate slide and the inner plates of the Sliding boards on the outer end plates of the intermediate slide to move past.
  • the figures show one from behind in the direction of production 10 seen left half of a screed 11 for the rest Paving machines, not shown.
  • the screed 11 is in the production direction 10 behind the paver attached.
  • the screed 11 is composed of a center divided main plank, of which only one on the left in the figures Half is shown. If necessary, both halves can the screed 10 may be connected to each other.
  • the main screed half 12 is provided with a shifting screed 13. Likewise, the (right) main plank half, not shown, has over a moving screed.
  • the respective screed 13 is via an intermediate slide 14 on the main screed half 12 stored.
  • the main screed half 12 and the shifting screed 13 have about the same width.
  • the shifting screed 13 is opposite the main screed half 12 transversely to the direction of production 10 displaceable, namely extendable into that in FIGS. 1 and 2 shown position and retractable into the in Fig. 3 and 4th shown position. In the extended position, the doubles Shifting screed 13 the width of the main screed half 12.
  • the main plank half 12 has at its outer end 15 via an outer end plate 16.
  • the opposite, for Longitudinal center axis of the paver pointing the end of the Main screed half 12 has an inner end plate 17.
  • the End plates 16 and 17 are rigidly connected to one another.
  • the moving screed 13 has an outer plate 18 and one Inner plate 19. Also the outer plate 18 and the inner plate 19 are rigidly connected.
  • the intermediate slide 14 has one towards the outer end 15 of the main plank half 12 facing outer end plate 20 and one towards the inner end plate 17 of the main plank half 12 facing inner end plate 21.
  • the outer end plate 20 and the inner end plate 21 of the Intermediate slides 14 are by two as opposite rails 22 trained support members connected with each other.
  • the intermediate slide 14 is on the opposite sides of its outer end plate 20 and its inner end plate 21 on firmly with the main plank half 12 connected guides 23 stored. This is the Intermediate slide 14 transverse to the production direction 10 between the inner end plate 17 and the outer end plate 16 of the Main screed half 12 movable.
  • the Distance between the outer end plate 20 and the inner end plate 21 of the intermediate slide 14 is less than the distance between the outer end plate 16 and the inner end plate 17 of the main screed half 12th
  • a Telescopic guide tube 24 On the intermediate slide 14, namely between the outer end plate 20 and the inner end plate 21 of the same is a Telescopic guide tube 24 attached. An extendable end 25 of the Telescopic guide tube 24 is firmly connected to the outer plate 18 of the shifting screed 13 Shifting screed 13 on the outer plate 18 through the telescopic guide tube 24. Furthermore, is between the inner end plate 17 of the main plank half 12 and the outer plate 18 of the Shifting screed 13 a pressure medium cylinder 32 is arranged. This serves to retract and extend the screed 13 opposite the plank half 12, with simultaneous (compulsory) Taking the intermediate slide 14. The inner plate 19 of the screed 13 is slidable as Guide rods 26 and 27 trained guide members of the Intermediate slide 14 stored.
  • the guide rods 26 and 27 project according to the invention facing the outer end plate 16 of the main screed half 12 outer end plate 20 of the intermediate slide 14 in front (FIG. 1 and 2).
  • the amount by which the guide rods 26 and 27 are opposite project the outer end plates 20 of the intermediate slide 14 is selected so that when the screed 13 is extended the Inner plate 19 of the same opposite the outer wall of the outer end plate 16 of the main plank half 12 to the outside is driven, so that the entire screed 13 laterally next to that through the outer end plate 16 of the main screed half 12 formed outer end 15 of the main plank half 12th lies (Fig. 1 and 2).
