ABSTRACT:
A concrete container for introducing concrete into formworks includes an upwardly open vessel with a downwardly narrowing bottom portion with an outlet opening and a flexible pipe connected to the outlet opening for distributing the concrete. Underneath the outlet opening of the concrete container, an essentially horizontally extending crossbeam is arranged, wherein the crossbeam is arranged so as to be displaceable transversely of the freely suspended flexible pipe. The two ends of the crossbeam, whose length corresponds at least to the diameter of the flexible pipe, are suspended from the concrete container by connecting members. Tension springs are attached in an articulated manner to the two ends of the crossbeam, wherein the other ends of the tension springs are fastened to the support frame, wherein the tension springs are tensioned when the crossbeam is located laterally of the outlet opening in a position releasing the flexible pipe. An adjusting member is connected in an articulated manner to the crossbeam, wherein the other end of the adjusting member is connected to the support frame of the concrete container, wherein the adjusting member serves to move the crossbeam against the force of the tension springs transversely of the flexible pipe.
