Module for the production of concrete parts, displacement body, use of a grid for the production of a module and concrete part

A module for production of concrete parts, comprising:

• a plurality of stacked rows of displacement bodies adjacently arranged in a horizontal longitudinal direction (L), which are clamped captively to a grid structure made of first and second at least two individual grids extending running in the longitudinal direction (L),
• wherein the first and second grids have grid surfaces oriented in a transverse or inclined manner relative in relation to the horizontal direction (L) and comprise 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 arranged at a distance from one another and oriented in a transverse or inclined manner relative the horizontal direction (L) and respectively connected with the longitudinal bars,
• wherein at least one of the displacement bodies in a bottom row of the stacked rows, on its outer side for each of the first and second grids comprises a first retaining device and at least one of the displacement bodies in a top row of the stacked rows, on its outer side comprises a retaining device,
• wherein the first and the second retaining devices are formed and arranged relative to one another so that both of the first and second grids are interlockingly and captively secured between the first and the second retaining devices by accommodating the first longitudinal bar in the first retaining device and accommodating the second longitudinal bar in the second retaining device thereby holding together all of the displacement bodies.
