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 vibrator and an attachment for a holder rotatably mounted in the vertical plane.
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.
Fig. 1 shows a side view, partly in section of the device according to the invention
Fig 2 shows the device according to fig. 1 in a view from above.
Fig. 3 shows in perspective a modified planation device according to the invention.
the planation device consists of a planation means II in the form of a trough shaped plate 11 with gently upwards bent edges 12. Inside the trough-shaped plate 11 transversely to this there are arranged two attachments 13. partly for supporting a vibrator 14 and partly as a holder for pivots 15 about which a clamp 16 is rotatable at one end of the holder 17. In order to get enough stability the plate 11 is equipped with diagonally arranged reinforcing springs 18 integrated with the bottom plate and firmly connected with the attachments 13.
the plate 13 is preferably manufactured of a light material such as aluminium or glass fibre reinforced plastic.
the device has such a low weight as possible and for this reason 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 20.
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 mens 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. For obtaining a good vibration effect it is necessary that the vibration waves extend over the whole plate substantially regularly, which is a difficulty when there are thin plates which should have a low weight, and which is provided by equipping the plate with said reinforcing springs 18.
planation means 11 consists of a single-curved, plate having a part-circular cross-section, where the vibrator 14 is arranged on the inside of the pipe like means 11. while the attachment 13 for the holder 17 is placed opposite the vibrator on the outside of the "pipe" .
planation means admits adjustment and/or displacement of relatively large amounts of concrete. with substantially the same favourable effect as the trough-like plate.
