Definitions

  • This invention relates to the field of concrete molds and more particularly to a method of assembling a concrete mold, particularly a concrete mold adapted to be placed in a formwork prior to a pouring operation.
  • displacement bodies are often arranged in the space surrounded by formwork in addition to reinforcement. This has the advantage that concrete can be saved and lighter concrete ceilings can be produced.
  • EP 1 568 827 A1 it is proposed to lock displacement bodies, which are designed, for example, as plastic balls, in latticework open to one side, and then press 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.
  • the module has a large number of displacement bodies arranged next to one another in a longitudinal direction, preferably plastic hollow spheres, plastic balls or plastic half-shells, the large number of displacement bodies arranged next to one another being arranged captively in a latticework of rods.
  • the module is intended to be pressed into a concrete layer, to be placed on a lower reinforcement or to be placed on a filigree slab.
  • the latticework has a channel-like shape with a narrow channel base and a wide channel opening and can be stacked to save space when displacement bodies are not used.
  • a module for the production of concrete parts, in particular semi-finished concrete products or relatively thin in-situ concrete slabs is known.
  • the module has a multiplicity of displacement bodies which can be used and are 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.
  • Each displacement body is designed as an essentially oblate ellipsoid of revolution with two at least slightly flattened pole sides.
  • a module for the production of concrete parts using the in-situ concrete method or in a precast plant which has a row of several in a horizontal longitudinal direction displacement bodies arranged next to one another, which are captively held in a latticework of at least two individual lattices running in the longitudinal direction, the lattice surfaces of which are aligned transversely to the horizontal, each of the lattices having at least one first and one second longitudinal rod, which run parallel and spaced apart from one another in the longitudinal direction, and a plurality of transverse bars spaced apart from one another and aligned transversely to the horizontal, each of which is connected to the longitudinal bars.
  • At least one of the displacement bodies has at least one first and at least one second holding device on its outside for each lattice, which are designed and arranged in relation to one another in such a way that both lattices can be fixed by receiving the first longitudinal bar in the first holding device and receiving the second longitudinal bar in the second holding device are fixed at least positively and captively between the first and second holding device and thereby hold together all displacement bodies.
  • the previously known concrete molding inserts have the particular disadvantage that their production is very complex. This is particularly so because very complex two- or three-dimensional lattices that are adapted to the size and shape of the displacement bodies to be used are required, which hold the displacement bodies and fix them in their position relative to the other displacement bodies.
  • the object is achieved by a positioning aid for use when assembling a concrete molding insert, in particular a concrete molding insert which is designed to be arranged in a formwork prior to a concreting process.
  • the concrete molding insert can be, for example, a concrete molding insert that is designed to be arranged in a formwork before a concreting process, including a first holding element and a second holding element, between which at least one displacement body is arranged, the displacement body having a passage tunnel and that the first holding member and the second holding member are connected to each other with at least one connecting member passing through the through tunnel.
  • the positioning aid is preferably designed and provided to temporarily hold at least one displacement body for an assembly process.
  • the positioning aid can advantageously be designed to hold the displacement body in such a way that it stands upright and cannot accidentally tip over.
  • the positioning aid can have recesses which have specifically for (in particular clamping) receiving, in particular protruding, parts of the displacement body and/or for receiving sections of the connecting component and/or for receiving one of the holding elements.
  • the positioning aid can be designed as a plate that has the aforementioned recesses.
  • the positioning aid can be made, for example, from a lightweight material, in particular from a foam material or a rigid foam material.
  • a plurality of positioning aids can be connected to one another, in particular by a form-fitting connection in each case.
  • the form-fitting connection can, for example, be designed in a manner similar to that of jigsaw puzzle pieces.
  • a positioning aid can be designed to hold a single displacement body upright for an assembly process. By connecting a plurality of such positioning aids, a positioning aid system can easily be produced which is individually designed for the required number of displacement bodies to be connected.
  • the assembly process of the concrete molding insert can, for example, take place in such a way that the required number of positioning aids are first connected to one another and laid out on the floor.
  • the first holding element and the required connection components are then inserted into the recesses of the positioning aids provided for this purpose.
  • the displacement bodies are positioned, with the connecting component in each case being guided through the passage tunnel and with protruding parts of the respective displacement body (e.g. protruding ribs and/or bearing elements) being inserted into the corresponding recesses of the respective positioning aid, so that the displacement body as a result is held upright by the positioning aid.
  • the connection components are coupled to the second holding element.
  • the finished concrete molding insert can then be detached from the positioning aids and brought to the place provided for a concreting process.
  • the positioning aids can then be reused for the assembly of the next concrete molding insert. Finally, the positioning aids can be separated again.
  • the positioning aids can advantageously be stacked on top of one another for transport. All positioning aids are preferably designed in the same way.
  • An advantageous method for producing a concrete molding insert which can be used flexibly and which can be carried out easily using the positioning aid according to the invention, can include that at least one displacement body, which has a through tunnel, in particular several displacement bodies, are arranged between a first holding element and a second holding element and that the first holding member and the second holding member are connected by a connecting member passing through the through tunnel.

  • first holding element and the second holding element do not need to have a size or shape specially adapted for the displacement bodies to be used.
  • the present invention advantageously makes it possible to deliver the required components to the construction site in a space-saving manner and to produce the concrete molding insert on site by simply assembling the components together, preferably without the use of tools. It is particularly advantageous here, for example, if the first holding element and the second holding element are each designed as a simple reinforcing bar. Such rebars are easily and inexpensively available and can be transported in a space-saving manner.
  • the concrete molding insert mentioned as an example has the very special advantage that the space surrounding the displacement bodies, in particular the space horizontally surrounding the displacement bodies, can remain free and there is therefore the possibility in this space (especially after a first concreting process, in which, for example, only one lower part of a concrete ceiling was concreted) to arrange additional reinforcements.
