Abstract: A module for the production of concrete parts has a row of displacement bodies that are adjacently arranged in a horizontal longitudinal direction (L) and that are clamped captively to a grid structure made of at least two individual grids running in the longitudinal direction (L). Surfaces of the grids are oriented in a transverse or inclined manner in relation to the horizontal. Each of the grids has at least a first and a second longitudinal bar arranged at a distance in parallel to one another and running in the longitudinal direction (L) and a plurality of transverse bars being arranged at a distance from one another and oriented in a transverse or inclined manner in relation to the horizontal. The transverse bars are respectively connected with the longitudinal bars. One of the displacement bodies for each grid has a first and a second retaining device.

Abstract: The invention concerns a half shell element (10) for the production of a hollow body with an identical further half shell element (10), with at least one guide (20 . . . 20??) for the further element (10), which is constructed in the region of a first half periphery (11) of its encircling edge (12), so that the further element (10) can be pushed onto the half shell element (10) from the second half periphery (11?) of the edge (12) lying opposite this first half periphery (11) and guided on the edge (12) and held in a final position. The hollow bodies which are thus produced can be both inserted into steel cages and also connected with each other via bars and built into concrete layers.

Abstract: Module (1) for the production of concrete elements, particularly of concrete semi-finished products or of relatively “thin” in-situ concrete surfaces. The modules includes a plurality of displacement bodies (5, 5?, 5?, 5??) able to be inserted and arranged adjacent to each other in a longitudinal direction. The plurality of displacement bodies (5, 5?, 5?, 5??) is arranged respectively undetachably in a latticework (2) of bars (3, 3?, 4, 4?, 4?). The displacement body (5, 5?, 5?, 5??) is formed as a substantially oblate rotation ellipsoid with two at least slightly flattened pole sides (7, 7?, 8, 8?).
