Furthermore, the invention relates to a process for the production of precast concrete parts, in which liquid concrete is conveyed from a stationary storage or mixing container to formwork and introduced into the formwork, and the liquid concrete via a top of the concrete formwork below the surface of the instant liquid concrete mirror dipping Downpipe is introduced. Such a method is known from JP-A-09 310 496 ,
  • the present invention seeks to develop a system and a method for producing precast concrete parts, whereby a segregation of the liquid concrete can be avoided.
  • a special feature of the invention is that the conveyor carries a moving concrete buffer mixer, a concrete hopper can be charged via the concrete buffer mixer concrete container, a connected to the concrete container concrete pump and via a relative to the mobile conveyor unit rotatable around a vertical concrete distribution boom conveyor line, wherein the delivery line to their end in a down at the top of the mast down, in the formwork from above immersed downcomer opens and the concrete boom and the concrete pump via control elements of a remote control are semi-automatically actuated.
  • a computer-aided control device for the conveying operation of the mobile conveyor unit, which includes an output data of a flow counter responsive control routine for controlling joint drives of the concrete boom in dependence on the derived from the measured flow rate of the formwork, which is programmed so that the downpipe at least over a part of the formwork height performs a stroke movement in a defined distance above or below the liquid concrete level in the formwork.
  • the downpipe can either be stiff or flexible end hose.
  • the traveling concrete pump is expediently working on the peristaltic principle rotor pump. This allows a very accurate volume determination by simply counting the rotor revolutions or parts of a revolution. This volume is then used together with the dimensions of the shape for height determination in the automatic high control of the downpipe.
  • Determining the volume during the pumping process also enables a level determination in the concrete buffer mixer, so that the liquid concrete can always be topped up in time. This can ensure that the concrete pump does not stand still during the entire concreting process.
  • the conveyor has a bucket conveyor or a bucket crane running along the route so that concrete bucket for refilling liquid concrete can be moved in the concrete buffer mixer arranged on the conveyor unit in accordance with the delivered delivery rate. The concrete from the buckets is homogenized in the concrete buffer mixer.
  • a further advantageous embodiment of the invention provides that the control device has a position sensor for automatically positioning the mobile conveyor unit with respect to the formwork to be loaded.
  • the control device has a position sensor for automatically positioning the mobile conveyor unit with respect to the formwork to be loaded.
  • a special feature of the method according to the invention for the production of precast concrete parts, in which liquid concrete is conveyed from a stationary storage or mixing container to a formwork and introduced into the formwork, is that the liquid concrete from above into the concrete formwork below the surface of the instantaneous liquid concrete mirror immersed downpipe is introduced, and that the downpipe is raised in the rise of the liquid concrete level in the formwork.
  • the downpipe engages equally far below the liquid concrete level.
  • the delivery rate of the liquid concrete introduced into the formwork is measured and the downpipe is automatically raised in accordance with the amount of liquid related to the cross-sectional area of the formwork.
  • a concrete pylon designed as a kink mast is expediently used, the downpipe being exposed to liquid concrete via a concrete pump and a delivery line guided along the mast arms of the kink mast.
  • the plant shown in fragmentary detail in the drawing is intended for the production of precast concrete parts.
  • the actual concreting process takes place in a delimited production zone 10 in which upwardly open formworks 12 are arranged, the inner contour of which corresponds to the contour of the prefabricated concrete part to be produced.
  • a non-illustrated reinforcing mesh is used in the formwork.
  • concreting liquid concrete is introduced from above through the openings 14 in the formwork 12 so that the reinforcing mesh is embedded in the concrete of the finished part.
  • the liquid concrete is produced in a stationary concrete mixing plant, not shown in the drawing and spent with a conveyor 16 in the formwork.
