Definitions

  • the present invention relates to a device for planation of a fresh concrete surface by means of surface vibration and comprising a planation means, provided with a pneumatic vibrator and an attachment for a holder, the vibration effect of said vibrator is adjustable at the free end of the holder by means of a flow regulating valve, (as f.i. disclosed in FR-A-45 310).
  • the FR-A-45.310 discloses a pneumatic vibrator arranged on a planation means in the form of a trough-shaped plate.
  • a holder is attached to the planation means and on the holder there is arranged a flow regulating valve for said pneumatic vibrator.
  • the object of the present invention is to provide a device which is suitable for planation of a fresh concrete surface without leaving any marks on the way to or from the place where the planation is to take place. Furthermore, the device should be so constructed that it can prepare very small volumes, which are to be levelled over a larger or smaller area, as well as larger volumes.
  • the drawing shows in perspective a planation device according to the invention.
  • planation device comprises a planation means 11 consisting of a single-curved plate having a part circular cross-section, where a vibrator 14 is arranged on the inside of the pipe-like planation means 11, while an attachment 13 for a holder 17 is placed opposite the vibrator on the outside of the "pipe".
  • the design of the planation means admits adjustment and/or displacement of relatively large amounts of concrete.
  • a pneumatically driven ball vibrator has been chosen as vibrator, the special feature of which is that its vibration effect can be adjusted from 0 to maximum and that it has a low weight.
  • the compressed air hose is placed in the holder 17 and is connected to the vibrator 14 by a pressure regulator.
  • the holder 17 which is rotatable in the vertical plane and which can have a length of several meters, for example 4 meters, consists of a light metal pipe and is at its end facing away from the plate equipped with a quick coupling 21 for connection to a compressed-air compressor and with a flow regulating valve 22 for adjusting the vibration effect by means of a handle 23.
  • the vibration effect can be adjusted from the free end of the holder 17 and the holder can be given a considerable length it is possible to prepare very large continuous concrete surfaces without entering upon the fresh concrete. It is also possible to move the device to a place where a surface process is to take place, and without the planation device leaving any marks.
