ABSTRACT:
A concrete container for introducing concrete into formwork, particularly into sliding formwork. The container includes an upwardly open container with a downwardly tapering lower portion having an outlet opening. A distributing hose is connected to the outlet opening. The vessel is provided with a support frame. The support frame can be connected to a lifting unit for lifting the concrete container. A pipe section is provided between the outlet opening of the container and the distributing hose. A motor-driven screw is mounted in the pipe section. The motor serving for driving the screw is mounted on the vessel or on the support frame. The axial length of the screw is slightly greater than the axial length of the pipe section. A support beam extending across the vessel is mounted on the upper rim of the vessel. The motor is flanged to the middle portion of the support beam. The drive shaft extends concentrically through the vessel. The pipe section is in alignment with the vertical center axis of the container.
