  • the outer shape of the displacement bodies each have a section designed in the shape of a truncated cone or a truncated pyramid.
  • the outer shape of the displacers is important, while the shape of the passage tunnel is not relevant for the beneficial effect mentioned above.

  • the invention has the very special advantage that the concrete molding insert can be manufactured in a simple manner in such a stable manner that the individual displacement bodies remain stably arranged relative to one another during construction and during the concreting process.
  • the individual displacement bodies remain stably arranged relative to each other, especially in the harsh everyday construction site environment, both during construction and during the concreting process, when construction workers walk around on the concrete molding inserts or on the concrete molding systems that contain concrete molding inserts according to the invention.
  • the displacement bodies are preferably designed as hollow bodies.
  • this has the very special advantage that the displacement bodies can be assembled from displacement body parts that can be stacked one inside the other, in particular at the location of the concrete part to be produced. This is advantageous both for the storage and for the transport of the displacement body, because less storage space and less transport space is required.
  • the section designed in the shape of a truncated cone or truncated pyramid is related to the direction of the connecting component and/or in relation to the direction of the Through tunnel has an axial height L, a narrow end with a radial width S and a wide end with a radial width B, where it applies that (BS)/L is in the range from 0.7 to 2.4, in particular in the range from 1 .1 to 2.0.
  • At least one of the displacement bodies is assembled from at least a first displacement body part and a second displacement body part.
  • the first displacement body part has the truncated cone-shaped or truncated pyramid-shaped section, with the truncated cone-shaped or truncated pyramid-shaped section extending (along the direction of the connecting component and/or in relation to the direction of the through tunnel) at least over a large part of the height of the first displacement body part extends.
  • the section designed in the shape of a truncated cone or a truncated pyramid extends to one end of the first displacement body part, at which the first displacement body part is connected to the second displacement body part.
  • the second displacement body part can in particular be designed in the shape of a bowl or pot, in particular with a circular or polygonal horizontal cross section. Such a shape also contributes to the great stability of the displacement body.

  • the second displacement body part has a height in the range from 2 cm to 30 cm, in particular in the range from 3 cm to 26 cm.
  • the first displacement body parts with a height in the range of 15 cm to 38 cm (e.g. in increments of 2 cm) and second displacer parts with a height in the range of 3 cm to 26 cm (e.g. in increments of 2 cm) concrete floors or concrete foundations with any thickness be produced advantageously in the range from 32 cm to 100 cm.
  • the displacement body parts are preferably fastened to one another, in particular without the use of tools, by means of a latching connection and/or a plug-in connection. This enables the displacement body parts to be assembled easily, quickly and therefore inexpensively, in particular at the point of use, namely on the construction site.
  • the connecting components can be elongate and have connecting elements at their ends for mechanical coupling to the first holding element and the second holding element.
  • the connecting elements can in particular be designed in such a way that they can be releasably coupled to the retaining elements without tools and/or non-destructively.
  • the connecting elements can advantageously be designed in such a way that they can be fixed to the holding elements without additional fastening means.
  • the connecting elements can be designed as latching elements, in particular as latching hooks.
  • the distances between immediately adjacent displacement bodies can advantageously be the same. This has the particular advantage that a vibrating bottle can be inserted everywhere in the same way into each of the spaces between adjacent displacement bodies in order to compact the liquid concrete there.
  • the first displacement body part can advantageously have a first passage tunnel part with a first passage tunnel wall.
  • the second displacement body part can also have a second passage tunnel part with a second passage tunnel wall.
  • the first passage tunnel part and the second passage tunnel part mutually support one another and together form the passage tunnel through which the connecting component runs.

  • a concrete molding insert in particular a concrete molding insert according to the invention, has different types of displacement bodies, in particular displacement bodies with different external shapes.
  • the load situation is similar, but in relation to a horizontal plane, in particular mirror-inverted, to the load situation in the case of a concrete ceiling.
  • the background is that the transverse forces within the concrete foundation, i.e. the forces in the vertical direction, increase in the direction of a wall or column foot standing on the concrete foundation, while the bending load decreases at the same time.
  • displacement bodies have only been used in an area of a concrete foundation in which mainly bending forces occur and the shear forces amount to a maximum of 50% of the maximum shear forces that can be absorbed by an otherwise identical concrete foundation without displacement bodies, i.e. mainly in the middle of the concrete foundation at a great distance wall or column feet.
  • the intermediate area between this area and the wall or column bases has so far remained free of displacement bodies.
  • An independent idea of the invention consists in arranging displacement bodies in this intermediate area as well, namely displacement bodies that each have a section designed in the shape of a truncated cone or a truncated pyramid. This is possible according to the independent idea of the invention because, as already mentioned above, these displacement bodies can be arranged particularly advantageously in relation to transverse forces. The advantage is particularly evident in the case of particularly thick concrete slabs, because displacement bodies have so far only been used in thick concrete slabs up to a line of 45% of the shear forces.
  • At least one other displacement body is arranged between the two holding elements, which displacement body has a different shape than the displacement bodies.
  • the other displacement body does not have a section designed in the shape of a truncated cone or a truncated pyramid.
  • the other displacement bodies can be arranged in the area of a concrete slab or a concrete foundation in which the shear forces amount to a maximum of 50% (45% in the case of thick concrete slabs) of the maximum shear forces that can be absorbed by the same concrete slab without displacement bodies, while the displacement bodies, which have a section in the shape of a truncated cone or a truncated pyramid, are preferably alternately aligned in opposite directions, at least in a part of the intermediate region in which the transverse forces are higher than 50% (45% in the case of thick concrete slabs) of the maximum transverse forces that can be absorbed by the same concrete slab without displacement bodies , can be arranged.

  • a concrete slab that has displacement bodies that are not truncated cone-shaped or truncated pyramid-shaped in a region spaced apart from the supports, in which the transverse forces amount to a maximum of 50%, in particular a maximum of 45%, of the maximum transverse forces that can be absorbed by the same concrete slab without displacement bodies Section, and which has displacement bodies in an intermediate area in which the transverse forces are more than 45%, in particular more than 50%, of the maximum transverse forces that can be absorbed by the same concrete surface without displacement bodies, which have a section designed in the shape of a truncated cone or a truncated pyramid.
  • the other displacement body preferably has a passage tunnel through which another connecting component connecting the holding elements runs.
  • the other displacement bodies are designed to be circular or oval in the vertical cross section (ie in a cross section that includes the direction of the passage tunnel and/or the connecting component).
  • the other displacement bodies are preferably also designed as hollow bodies.
  • this has the very special advantage that the other displacement bodies can also be assembled from displacement body parts that can be stacked one inside the other, in particular at the site where the concrete part is produced. This is advantageous both for the storage and for the transport of the other displacement bodies, because less storage space and less transport space is required.

  • first other displacement body part and the second displacement body part are of identical design and/or that the second other displacement body part and the second displacement body part are of identical design.
  • This has the very particular advantage that, overall, fewer different types of displacement body parts are required to produce the concrete molding insert. Rather, one type of displacement body parts can be used both for producing a displacement body that has a truncated cone-shaped or truncated-pyramid-shaped section and for producing a displacement body that does not have a truncated-cone-shaped or truncated-pyramid-shaped section.
  • the first displacement body part and the first other displacement body part have the same height in relation to the direction of the connecting component. This has the particular advantage that by using these displacement body parts in combination with second displacement body parts of the same height and other displacement body parts, displacement bodies of the same height and other displacement bodies can be put together as a result.
  • the other displacement body parts are preferably fastened to one another, in particular without the use of tools, by means of a latching connection and/or a plug-in connection. This enables the other displacement body parts to be assembled easily, quickly and therefore inexpensively, in particular at the point of use, namely on the construction site.
