Definitions

  • the present invention relates to a machine for striking off poured concrete composed of frame parts which carry the elements for striking off the concrete and the control members thereof, which frame parts are equipped with wheels, at least some of which are drive wheels.
  • the concrete surface Upon construction of monolithic concrete floors, the concrete surface is mostly struck off manually with vibration beams or struck off strokes. If it concerns larger surfaces, it is already possible to strike off the concrete surface by means of machines which are provided with vibration beams and instruments pertaining thereto. To enable to strike off an as large as possible surface, these machines are provided with a telescopic arm to which the striking off means are applied. This was realised for always enabling to strike off a distance as large as possible. These machines are always set up out off the poured concrete and operate from a stationary position.
  • a second clear drawback is the pressure which is exerted by the weight of the machine through the intermediary of the rods of the cage wheels onto a plastic foil or a clay cloth.
  • the often used plastic foils or clay cloths onto which the liquid concrete is poured, are in the widths used therefor, never resistant to the pressure exerted by the cage wheels, while the rotation of these cage wheels over these foils or cloths regularly tears the foil material.
  • An object of the invention is therefore to provide a machine which enables to achieve striking off concrete floor surfaces under all circumstances on a very flexible manner, without damaging the foil materials described hereinabove.
  • said wheels are equipped with tires having a tire width of substantially 18 cm.
  • Figure 1 is a schematic side view of the machine according to the invention.
  • Figure 2 is a schematic top view of the machine in a position wherein both frame parts and the arm connected to the first frame part are directed according to one and the same centre line.
  • Figures 3 and 4 are, on a smaller scale, two schematic views of different arrangements of the arm with respect to the first frame part and of the support beam with a striking off unit connected to the arm.
  • Figure 5 is, on an enlarged scale, a schematic side view of the first frame part and of the support and transverse beams mounted thereon.
  • Figure 6 is a schematic front view of the support beam with the striking off unit mounted thereto.
  • Figure 7 is a view similar to the view according to Figure 6, but with respect to an alternative.
  • Figures 8 and 9 are, on a smaller scale, two schematic views of the machine such as represented in Figures 3 and 4, but with respect to an alternative.
  • the machine illustrated by these figures, consists in the embodiment described herein by way of example, of a first frame part 1 and a second frame part 2 which are hingedly connected to each other at the vertical hinge axis 3.
  • the first frame part 1 carries the required instruments for striking off the poured concrete while the second frame part is equipped with the different mechanic and hydraulic control members of the machines.
  • Very characterising for this embodiment of the invention is the presence of each time two narrow wheels 4 as well on the first as on the second frame part.
  • the diameter of the wheels 4 and the thickness of the tires 5 which equip these wheels are calculated in such a manner that the machine can be moved without problems through the poured concrete.
  • without problems it is meant :
  • Handling the machine occurs on a technically very reliable manner by mounting a hydraulic cylinder 6 between the first frame part 1 and the second frame part 2.
  • This hydraulic cylinder with hinge point 7 on the first frame part and 8 on the second frame part is illustrated with a dotted/dashed line in Figures 1, 3 and 4.
  • a hydraulic cylinder 6 By using a hydraulic cylinder 6, a simple and light control of the machine is rendered possible and the first frame part 1 and the second frame part 2 can be set up under very different angles with respect to each other. This is illustrated i.a. in Figures 3 and 4.
  • an arm 9 is mounted with the possibility to turn.
  • the arm 9 is mounted with respect to the first frame part through the intermediary of a rotary ring 10.
  • a hydraulic cylinder This cylinder 11 has its first hinge point 12 on the rotary ring 10 and a second rotation point 17 on the first frame part.
  • This second hydraulic cylinder 11 permits to set up the arm with respect to the frame part under a plurality of angles with respect to each other. Also this is very clearly illustrated in Figures 3 and 4.
  • the arm 9 which can be turned on itself with respect to the first frame part in the horizontal plane is, approximately at free end height thereof, provided with a second rotary ring, which is illustrated Figures 2, 3 and 4 with reference 13.
  • the transverse beam 14 is fixed.
  • the support beam 24 is fixed and this through the intermediary of a number of parts which will be explained further in detail.
  • the turning of the transverse beam 14 with respect to the arm 9 is realised here by a hydraulic cylinder 15, with a first hinge point 16 on the transverse beam and a second hinge point 17 on the rotary ring 13.
  • a hollow column 18 is mounted each time on its extremity. This hollow columns serve to guide tubes in up- and downwards direction.
  • hydraulic cylinders 20 are mounted parallel to these tubes, on the one hand to the tubes and, on the other hand, to the transverse beam.
  • the sensors 21 act on a laser beacon, as known, which has not been illustrated in the figures.
  • the support beam 24 is suspended to the tubes 19 by means of a knee joint 23.
  • a scraper 25 is fixed to this support beam 24.
  • a roller 26 is also fixed to the support beam, the rotation direction of which is opposite to the direction wherein the machine moves.
  • the support beam 24 serves also as suspension point of a vibration beam 27 which is driven by vibration motor 28.
  • Small hydraulic cylinders 29 are hingedly connected, on the one hand with the support beam 24 and are connected, on the other hand, with an arm 30 at the bottom of the tubes 19.
  • the object is to be allowed to modify the horizontal position of the support beam and thus to adapt it to the local or temporary requirements.
  • the machine shows, as it appears from the description and the figures annexed hereto, a very compact and light structure.
  • the required means for striking off the concrete can be set up and used under very different angles, as it appears from these figures.
  • the machine can be provided with wheels equipped with tires, which solves hitherto very inconvenient problems.
