Definitions

  • the invention relates to a device for smoothing a concrete surface after the installation of fresh concrete according to the generic term of claim 1.
  • Such devices are needed to make road surfaces To produce concrete. You can set up in a slipform paver be integrated or as an attachment to one Slipform paver or other road construction machine be used with a tractor.
  • Slipform pavers provide a continuous advance concreted areas, such as roads, concrete slopes and the like.
  • front of the slipform paver is from a truck or with the help of special devices such as loading devices Fresh concrete piled up.
  • the concrete is first turned crosswise to the direction of travel equally distributed. Subsequently is moved back and forth across the direction of travel, smoothes a cross smoothing device that slight bumps in the still fresh concrete surface.
  • a longitudinal smoothing device is located behind the transverse smoothing device arranged the additional the surface of the still fresh concrete surface smoothes.
  • DE-A-30 36 234 describes a device for smoothing a Concrete surface known, which has a cross and a longitudinal smoother used to remove the unevenness of the fresh concrete.
  • the cross straightener consists of a pendulum plank, which is immediately located behind a screed.
  • the pendulum plank can be adjusted in height using two handwheels.
  • the pendulum movement of the screed is carried out with the help of an eccentric drive realized.
  • the length straightener consists of a smoothing plate, this is articulated on a carriage by means of two pairs of struts is suspended, movably mounted on a cross member, can be moved across the machine width transversely to the direction of travel.
  • This crossbeam is fixed to the machine frame via extension arms connected and, seen in the direction of travel, far behind the Cross straighteners arranged. This is done via an eccentric drive
  • the smoothing plate is moved back and forth parallel to the direction of travel.
  • the Suspension of the longitudinal plate is designed so that the movement of the longitudinal plate of the surface contour of the fresh concrete is adjusted.
  • the disadvantage here is that the space required by the arrangement of the cross smoothing and the longitudinal smoothing is very large. Thereby, that the longitudinal smoother seen in the direction of travel, very far behind enough at the back, an additional support for the longitudinal straightener be provided. Another problem is that the well-known longitudinal smoother not with a roof-shaped profile the concrete surface can be used.
  • the invention has for its object a device to create the type mentioned at a roof-shaped Profile of the concrete surface the movability of a work facility across the entire working width.
  • the invention advantageously provides that the transverse smoothing device for the production of a roof-shaped profile Concrete surface from two, in the middle of the working width there is articulated cross screed, and that a working device is movable on the transverse smoothing device is attached and over the entire working width of the machine frame is movable on the transverse smoothing device.
  • the transverse smoothing device as a guide for an additional over the Working width adjustable work equipment is used.
  • the overall length of the machine can be shortened considerably, with an additional cross member as a guide device can be omitted for the work equipment.
  • the working device of the transverse smoothing device set roof shape of the concrete surface follows. When installing extension segments up to one The guiding device also becomes a working width of approx. 16 m extended for the working direction without a further conversion would be necessary.
  • the transverse smoothing device has a movable over the entire working width of the machine frame Has carriage on which the work equipment is attached.
  • the transverse smoothing device thus serves as a guide device for a carriage, the guide device preferably made of There are rails on which the rollers of the carriage roll can.
  • the mutually facing ends of the rails a parallel to the track segment running the track is arranged, that when setting a roof-shaped concrete surface profile bridging gap between the rails, and that the carriage is provided with double rollers, the both on the tracks and on the track segment can support.
  • the career segment enables the stepless Transition from the guiding devices of a cross screed to the guide devices of the other cross screed. This makes a work facility across the working width so movable that they exactly the roof-shaped Profile of the concrete surface follows.
  • the track segment is preferably on one of the two cross screeds attached.
  • the two career segments can also slide against each other.
  • the transverse smoothing device is preferably via coupling links suspended from the machine frame. That way an oscillating transverse movement of the transverse smoothing device is possible.
  • the transverse smoothing device is preferably a parallelogram hung on the machine frame.
  • the cross smoothing device is in terms of working depth and Infinitely adjustable longitudinal pitch angle.
  • the pitch angle refers to a setting angle for the cross screed in the direction of travel .
  • the Working device from a longitudinal smoothing device.
  • the invention is particularly advantageous with a longitudinal smoothing device usable. With a longitudinal smoothing device that has a high If space is required, the reduction in overall length is particularly important Advantage.
  • the longitudinal smoothing device can be independent of the Adjust the cross smoothing device. This is important in this respect than the movements of the transverse smoothing device do not coincide with the Superimpose movements of the longitudinal smoothing device.
  • the device is preferably in a slipform paver integrated, so that its overall length can be significantly reduced can.
  • the device can also be used as an attachment to another Road construction machine can be attached or stand alone Be a machine with its own chassis.
