Abstract

A device for planation of fresh concrete surface by means of surface vibration and comprising a planation means (11), equipped with a vibrator (14) and an attachment (15) for a holder (17) rotatably mounted in the vertical plane. The purpose is to provide a device which is suitable for planation of a fresh concrete surface without using screeding paths or levelling means and without leaving any marks on the way to and from the place where the planation is to take place. Furthermore it should be possible to level very small as well as large volumes of concrete over a larger or smaller surface. These objects have been attained by the fact that the vibrator regarding the vibration effect is adjustable, and that at the free end of the holder a regulating device is applied for adjusting of vibration effect.

Description

  • 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 demands for surface smoothness on e.g. concrete floor surfaces are now relatively high and there is a desire that already at the planation of the fresh concrete such a high smoothness should be provided, that no subsequent curings are needed. It is especially difficult to achieve a sufficiently level surface for large continuous surfaces, particularly if screeding paths or other levelling means may not be used or has already been removed in order not to leave any marks on the floor surface.
  • Up to now manual methods have been used for the final planation, namely planation with a float or steel grinding with a steel disk. Any remaining surface irregularities have been prepared after the hardening of the concrete.
  • It is also known to use so called vibrating screeds for working at large surfaces, which, during moulding, are divided into long strips and where the screeds rest on edge moulds during the vibration. If the edge moulds are taken away from the fresh concrete damage will occur which must be mended in some way.
  • At smaller concrete moulding works so called vibrating shovel compactors are used, but this tool only compensates the hand tamping of the concrete with vibration. This tool is not adapted for finishing e.g. providing a surface planation, as the vibrator of the shovel acts to the bottom of the concrete causing a too high, vibration effect. Besides the vibrator shovel is very labour demanding and because of its heaviness causes high strains on the back and arms.
  • 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. These objects have been attained by the fact that said vibrator is a light weight ball vibrator and that the planation means consists of a single-curved plate with a preferably part-circular cross-section and on the inside provided with said vibrator and on the outside opposite the vibrator with the attachment for the holder, which is rotatably mounted in the vertical plane.
  • The drawing shows in perspective a planation device according to the invention.
  • The planation device disclosed in the drawing 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.
  • It is very important in this connection that 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.
  • 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.
  • As 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.
  • The invention is not limited to the shown embodiment but a plurality of variants are possible within the scope of the claim.
