Definitions

  • the invention relates especially to systems for the production of precast products from concrete and similar moulding materials.
  • precast concrete products are, possibly enforced, cable troughs, cattle slats, posts, bumper blocks, manholes, lintels, preformed wall parts, building panels and many others.
  • This type of equipment can be constructed for a large number of applications in such a way that no special foundations are required and that they can easily be assembled and moved to another location.
  • Filling of the mold can be done through a charging hopper which itself can be filled in any known way, for instance by a belt conveyor or with some lever apparatus.
  • the mould may be provided when needed with a suitable reinforcement. After opening the locking members of the charging funnel the concrete mix falls down into the mould. After vibration and leveling a pallet may be positioned on top of the mould frame and clamped to it. After turning upside down the mould and releasing the clamps the shaped concrete remains on the pallet.
  • the pallet may be piled up to a predetermined height and moved to the drying space.
  • the concrete moulding apparatus is characterized by an equalizing beam which is coupled to a drive mechanism, and can be moved in a horizontal as well as in a vertical direction and has at its lower side a free horizontal surface adapted to the upper surface of the mould, the drive mechanism being provided with one or more eccentrics enabling the lower beam surface to carry out circular movements over the mould surface while the beam moves over it.
  • Supply of new concrete mix, movements of the beam and the removal system of the mould are mutually coordinated.
  • the scouring system 20 proper shows the following parts: (figures 1 and 2)
  • the eccentric axles 3 start moving.
  • the lower eccentric part 14 of axle 3 can rotate freely in casing 4 of support 1.
  • the latter starts moving and in this way exercises a scouring action with respect to frame 7 and the surface of mould 10, situated below the scouring surface 25 of scouring beam 2. All points of the scouring beam are carrying out a circular movement.
  • the diamecer of the circles corresponds to the eccentricity of driving shaft 3. It is this type of moving that smoothes efficiently the surface of the concrete filling in the mould.
  • the screed mechanism must also be movable in a horizontal direction over the surface of the concrete in the mould in order to remove the concrete excess.
  • the screed mechanism should also be movable in a vertical direction. During this vertical movement the scouring surface 25 must maintain its horizontal extension. To this effect use can be made of a certain co-ordination with the movements of the filling device 13 combined with a parallelogram type of construction for driving.
  • the filling carriage 16 is filled from filling bunker 13.
  • the carriage moves over mould 9 and fills it to the brim.
  • the dosing valve 17 moves to a predetermined height.
  • the filling carriage moves back again and in this way doses just a little bit too much.
  • the valve 17 closes on reaching the end of the mould and all excess of fill material is taken along.
  • the vibrational treatment starts.
  • the dosing valve 17 and valve 18 move upwards and filling carriage 12 moves forwards over the mould. This time the concrete is not taken along but remains on table 15.
  • the scouring system moves downward to the mould surface and starts scouring.
  • This solution has been mainly developed in order to provide existing machines with the scouring system according to the invention.
  • the scouring system 2 descends on the mould and starts scouring.
  • the upper parallelogram 23 moves the scouring system forward and backward over the mould surface. This results in closing the surface structure.
  • the scouring beam 2 may consist wholly or in part of metal, wood or plastic.
  • the scouring surface 25 There is also a wide choice for the scouring surface 25. The best results were obtained with hard wood and stainless steel.
  • the purpose is to obtain an effectively scouring surface of high stability that may be formed and/or shaped in any known way. Preferably it is a closed plane that is not interrupted by open spots or other disturbances. Satisfactory results were, however, also obtained with scouring surfaces of some other shape such as a partly open frame.
