Definitions

  • the invention relates to a screed according to the preamble of claim 1.
  • a screed according to EP-A-493 889 (Fig. 1 and 2) is used as one of the guide devices the extending screed is the base section of a telescopic tube arrangement which is fixed to the base board used, the extendable end section on the outer cheek the screed is attached.
  • Second from the first across to the direction of extension spaced guide device is used on the support structure for the extending screed Attached guide bar, which is attached to an outer screed cheek Torque support engages.
  • the torque arm takes on torsional moments the screed around the first guide on the base portion of the first Guide device is in the outer base screed and in a near the Longitudinal center of the basic screed integrated inner basic screed cheek attached.
  • the sliding guide engages around the base section, such that they are between the insides of the two basic screed cheeks can move.
  • the sliding guide is connected to the support structure of the extending screed and even protrudes over the end facing the center of the base pile.
  • the screed is driven by a hydraulic cylinder on the inner screed beam is supported and attacks the outer extending screed cheek.
  • the distance from the central screed longitudinal center positioned inner base screed and the thickness of the sliding guide the available extension stroke is shorter than half the screed length.
  • known screed serves as a guide device for the extending screed a telescopic tube arrangement fastened in the base screed, the free, extendable end coupled to the outer cheek of a support structure of the extending screed is.
  • a second guide device is provided by a on the back of the support structure arranged guide bar and one on the outer base screed attached torque arm acting on the guide bar.
  • On the inside is the supporting structure of the screed supported with a sliding guide, which as further guide device uses the base section of the telescopic tube arrangement and can be moved back and forth between the basic screed cheeks. Because the usable The travel stroke is shorter than half the base screed or transport width Do not completely double the basic width when extending screeds.
  • Screeds are also known, in which either the basic screed or the Extending screed has an additional telescopic section which enables double the basic or working width of the basic screed and the required transport width adjust.
  • the invention has for its object to a screed of the type mentioned create that allows the basic or other in a structurally simple manner Double the transport width of the basic screed as far as possible with the extending screeds or even exceed. It is also important in this regard, the proven stable inside The screed is supported as in the screed concepts mentioned at the beginning with a limited extension stroke.
  • the sliding guide of the support structure of the extending screed when retracted Extending screed across the longitudinal center of the base screed into the opposite can be clearly shifted by shifting the base plank half extend.
  • the supporting structure remains and thus the extending screed inside the base screed in a proven manner stably supported. Because the sliding guide is far enough when extending the screed If it remains behind the extending screed, the extending screed can be extended further the sliding guide into one through the inside of the outer base beam defined end position. Then the basic width is doubled or have the screeds extended even further.
  • the guide devices and the sliding guides are offset, so that the two sliding guides can pass each other.
  • the guide device for the sliding guide extends to into the opposite base screed half, so that the sliding guide over the entire travel stroke remains properly supported.
  • the base section of the telescopic tube arrangement serves which forms a guide device for the screed, at the same time also as a guide device for the sliding guide, which therefore does not have its own guide device needed.
  • the two telescopic tube arrangements are transverse offset from each other to the pull-out direction to the sliding guides during adjustment to pass each other in the fully retracted position.
  • a guide rod fixed in the base screed preferably between its cheeks or a guide tube is provided.
  • the telescopic tube arrangement leads and mainly supports the screed over its outer cheek.
  • the guide rod guides and supports the screed over the sliding guide. Because these two Guide devices are spaced, so are also tilting or twisting moments the extending screed.
  • the drive can be a hydraulic cylinder with a long stroke be, or a pneumatic cylinder, a rack and pinion drive or the like.
  • the guide devices for the sliding guide in the vertical direction offset to each other, so with both screeds in approximately the same support conditions available.
  • the distance between the guide rod and the torque arm larger than the distance between the guide rod and the telescopic tube arrangement, torque of the screed with the largest possible lever arm to be able to record.
  • the drive is integrated in one of the guide devices, to save space and possibly reduce the number of components.
  • the support structures of the extending screeds have open ends Entry recesses for the other sliding guide.
  • a continuously movable additional screed on each screed removably attached is a continuously movable additional screed on each screed removably attached.
  • Working widths can be achieved with the additional extending screeds set that much more than twice the basic or transport width the base screed. In the event that there are no such large working widths the additional screeds can be easily removed.
  • This concept has independent inventive meaning and is not in the concept of one Screed bound, with the extendable screeds almost twice the basic width can be adjusted.
