Container for introducing concrete into formwork
First Claim
1. A concrete container for introducing concrete into framework, the container comprising a vessel having a top and a bottom, a support frame for supporting the vessel, the vessel being open at the top thereof and having a downwardly and inwardly tapering lower portion, the lower portion defining an outlet opening, a pipe section connected to the outlet opening, and a distributing hose for introducing concrete into formwork connected to the pipe section, further comprising a screw mounted within pipe section, a motor for driving the screw, the motor for driving the screw being mounted on the vessel, a current source for the motor mounted on the support frame, actuating members for controlling the current source, the actuating members being mounted at an opening of the distributing hose, the pipe section having a length, the screw having an axial length which corresponds to or is slightly greater than the axial length of the pipe section, the screw having an average pitch selected smaller than 45°
- for preventing concrete from flowing out of the vessel when the screw is not rotating.

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.
