Abstract: A method of erecting a building ceiling in a structure having a floor plate and a circumferentially closed building wall erected on the floor plate, wherein a ceiling plate is manufactured on the floor plate, and wherein the circumferential contour of the ceiling plate corresponds to the inner contour of the building wall. Together with a circumferentially closed and water-tight side wall, the ceiling plate forms a floating body. Water is filled into the space defined by the inner side of the housing wall and the side wall, so that the floating body floats upwardly. When the ceiling height has been reached, the ceiling plate is connected to the building wall.

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.

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.
