Definitions

  • the invention relates to a displacement body which is designed to be arranged in a formwork prior to a concreting process.
  • the invention also relates to a concrete molding insert with a plurality of displacement bodies.
  • displacement bodies are often arranged in the space surrounded by formwork ⁇ . This has the advantage that concrete can be saved and lighter concrete slabs can be produced.
  • EP 1 568 827 A1 proposes enclosing displacement bodies, e.g. in the form of plastic balls, in latticework that is open on one side, and then pressing these modules into a first or second layer of concrete, which can already contain a first reinforcement mat. The semi-finished product produced in this way is then covered with concrete during later completion.

That The module has a multiplicity of replaceable displacement bodies arranged next to one another in a longitudinal direction, with the multiplicity of displacement bodies arranged next to one another being arranged in a captive manner in a lattice work of rods.

  • the previously known concrete molding inserts usually have the disadvantage that they can be used specifically for a specific size range of a concrete part to be produced. To that extent it is necessary, for example, to keep smaller displacement bodies ready for the production of thin concrete slabs, while larger displacement bodies have to be kept ready for the production of thicker concrete slabs.

Intermediate stages are also possible, which is explained in detail further below. In particular, it is possible for a large number of different effective heights to be realizable with one and the same components.
  • Each of the receiving devices is preferably arranged either above or below the closed shell of the displacement body.

  • the rebars (apart from their immediate contact with the respective fixture, which is negligible) are completely surrounded by the concrete when filled with concrete and a good bond between steel and concrete is obtained everywhere, which would not be the case if a rebar would lie directly against the closed shell.
  • complete enclosing of the rebars with concrete is also important in the event of a fire.
  • the concrete acts as a protective shell, particularly with regard to cooling the reinforcing bars.
  • the complete encapsulation of the rebars is also important as a protection against corrosion. It should be noted that cracks can form in concrete components, especially in concrete ceilings, through which moisture can penetrate. If the rebars are completely enclosed by concrete, the penetrating moisture only reaches a small section of the respective rebar. However, when the rebar rests on the hollow body ⁇ , moisture can seep between the rebar and the hollow body, reaching and damaging much larger areas of the rebar.
  • the receiving devices are each designed to hold a rebar at a distance from the closed shell that is at least half the size of the largest grain of the selected concrete granulation.

  • a stone can also move through the gap between the closed shell and the rebar, which is larger in one direction than the distance between the rebar and the closed shell, as long as the stone is smaller than the distance in another direction between the rebar and the closed shell (which is almost always the case).

Abstract

L'invention concerne un corps de déplacement qui est configuré pour être disposé dans un coffrage avant une opération de bétonnage. Le corps de déplacement a au moins un premier dispositif de réception, qui est configuré pour maintenir une barre d'armature s'étendant dans un premier plan à une certaine distance de la coque fermée et/ou d'un plan de référence, en particulier horizontal, de la coque fermée. Le corps de déplacement a également au moins un deuxième dispositif de réception, qui est configuré pour maintenir une barre d'armature s'étendant dans un deuxième plan, qui est parallèle au premier plan et espacé de celui-ci, à une certaine distance de la coque fermée et/ou du plan de référence de la coque fermée. Le corps de déplacement a également au moins un troisième dispositif de réception, qui est configuré pour maintenir une barre d'armature s'étendant dans un troisième plan, qui est parallèle au premier et au deuxième plan et espacé de ceux-ci, à une certaine distance de la coque fermée et/ou du plan de référence de la coque fermée.
