  • the present invention seeks to develop an arrangement for the production of concrete components with a control valve, which allows with the support of a liquid concrete pump and a conveyor line connected to this continuous filling a formwork without segregation phenomena with uniform concrete quality even over large concreting heights. Another object is the advantageous use of such arrangement in the manufacture of concrete components using liquid concrete.
  • the invention is based primarily on the idea to provide in the arrangement according to claim 1, a control valve for liquid concrete, having a housing with an inlet nozzle, an outlet nozzle and a connecting piece, in which a control member for reversing a liquid concrete flow is arranged.

This ensures that the liquid concrete introduced into the housing under pressure via the inlet connection can be temporarily discharged via the outlet connection into a formwork and that the connecting piece is always supplied with liquid concrete for further transport to other control valves or exit points both with open and closed outlet nozzle.
  • a preferred embodiment of the invention provides that the control member is designed as in an aligned with the outlet nozzle cylinder between the output nozzle against the inlet port shut-off closed position and the outlet nozzle relative to the inlet nozzle releasing open position movable piston and that the connecting piece both in the open position also communicates with the input port in the closed position of the piston.
  • This can be achieved in particular by the fact that the outlet nozzle is angled relative to the inlet nozzle, that the connecting piece is aligned with the inlet nozzle, and that the piston engages sealingly in its closed position in the outlet nozzle and in its open position so pulled out of this, that he Passage from the inlet nozzle to the outlet nozzle and to the connecting piece releases.
  • the piston has a transverse to its direction of passage breakthrough, which releases the passage from the inlet nozzle to the passage in the closed position of the piston.
  • the control member can be operated either manually or by hydraulic, pneumatic or electromechanical means. Manufacturing technology, it is advantageous if the cylinder is connected to a cylinder flange of the housing. In this case, the cylinder containing the control member can be manufactured separately from the housing and then flanged or coupled by means of a pipe coupling.
  • Control fittings of the type described above are used according to the invention in an assembly for the production of concrete components using liquid concrete
  • the arrangement comprises a formwork, which is bounded by at least one vertically oriented formwork wall by the control valve with its inlet nozzle and its connecting piece to an input side with a conveyor connected to liquid concrete pump is connected, and wherein the control valve opens with its outlet nozzle in the formwork to be filled.
  • the outlet nozzle is aligned with its end face with the interior of the shuttering wall and the piston in the closed position with its bottom reaches to the front side of the outlet nozzle.
  • the end face of the outlet nozzle and the bottom of the piston forms a smooth boundary surface aligned with the interior of the shuttering wall.
  • the invention is therefore, according to claim 1, an assembly for the production of concrete components using liquid concrete, with a formwork, which is bounded by at least one vertically oriented formwork wall, and with a liquid concrete pump comprising a device for introducing liquid concrete into the formwork, wherein on the outside of the formwork wall, an inlet side connected to the liquid concrete pump conveyor line is arranged, which has at least two superimposed, interconnected via a connecting line horizontal strands, wherein in the horizontal strands in each case at least one control valve is arranged, which an inlet nozzle, an outlet nozzle and a connecting piece has, each control valve is coupled with its inlet nozzle and its connecting piece in the associated horizontal strand and hindu with its outlet nozzle through an opening of the shuttering wall rch opens into the formwork, wherein the outlet nozzle is communicated in an open position of an arranged inside the control valve control member with the inlet nozzle and shut off in a closed position of the control member relative to the inlet nozzle, and wherein the connecting piece both in
  • control valves separately controllable.
  • at least two control valves can be arranged in the horizontal strands at a lateral distance from each other.
  • several horizontal strands can also be connected to one another via connecting lines in a meandering manner.
  • a gate valve is expediently arranged, which makes it possible to continue the insertion process from bottom to top and successively incorporate the respectively arranged horizontal strands in the delivery line.
