  • the formwork 8 consists of a frame 10, which represents the outer boundary of the concrete part 9 and either individually made from the usual formwork materials for each concrete part or, in the case of series production of the concrete part 9, from a reusable, prefabricated, solid frame.
  • the height h of the frame 10 gives the Concrete thickness H of the concrete part 9 before
  • a reinforcement 12 for the concrete part 9 housed in the present embodiment consists of reinforcing bars made of structural steel or plastic, and only is indicated schematically.
  • the reinforcement can e.g. B. still lattice girder or additional Have anchoring bracket in the area of the formwork part 1.
  • the frame 10 is filled with concrete as usual and painted smooth.
  • the cavities 4a and 5a of the fastening elements 3 are filled up to the upper edge of the formwork wall 2, expediently the cavities 4a and 5a by suitable covers be closed so that these cavities are not accidentally filled with concrete become.
  • the concrete within the cavity 2a of the formwork part 1 and Concrete within the frame 10 of the formwork 8 go through the openwork Formwork wall 2 a monolithic connection, so that the formwork part 1 remains as lost formwork in the concrete of the concrete part 9 and an optimal connection to the in-situ concrete that was later brought to the construction site.
  • the finished concrete part 9 contains, as shown in FIG. 3, a base plate 9a with which by Height h of the formwork 8 conditional concrete thickness H, as they are usually called Semi-finished part for the production of ceilings industrially prefabricated and on the construction site was delivered.
  • the base plate 9a has one or more Concrete base 13 provided with a height K above the surface of the base plate 9a protrude. These concrete bases 13 were through the cavity 2a of the formwork element 1 formed and enclose the fasteners 3 in a manner that there is no fear of buckling, breaking off or other damage are. Nevertheless, the concrete part 9 can still be easily transported, for example, by stacking the components on top of one another as usual, the Base plate of the upper concrete part 9 on the concrete base 13 of the lower concrete part 9 rests.
  • the front right concrete base 13.1 was made using the formwork part 1 1 and 2 and has the upwardly open cavity 5a of the receiving sleeve 5, a holding bar of a scaffold or a support, one Post of a fall protection, for example in the form of a railing, the anchoring part for inclined support or the like.
  • the concrete base 13.1 also contains the laterally open slot 4b in the example with With the help of cap screws or similar formwork panels for connection formwork or other attachments can be inserted.
  • the right rear concrete base 13.2 was made using a formwork part 1 made in which the rail 4 replaced by a slightly modified rail 14 has been.
  • the rail 14 was on the side facing away from the cavity 2a Formwork wall 2 attached and is with its back with the cavity 2a in Connection.
  • the rail 14 also has a cavity 14a and one to the outside having slot 14b, both over the entire length of the rail 14th run through.
  • the fastening element 3 designed as a rail 14 is particularly suitable for the subsequent attachment of facade parts or the like.
  • the left, rear concrete base 13.3 was made from a formwork part 1, at which the receiving bushing by a fastener provided with a threaded bush 15 3 was replaced.
  • the threaded bush 15 is with the help of a support plate 16 fixed over the cavity 2a of the formwork wall 2 so that its axis runs perpendicular to the base plate 9a. Bolts can be inserted into the threaded bushing 15 or screws of supports or other attachments.
  • the rail 4 from FIG. 1 was by a screw block 17th replaced, in the screw holes drilled from the outside at the desired locations can be, for example for attaching a connection formwork or the like.
  • the screw block 17 is preferably made of wood or plastic and is in illustrated embodiment in an undercut indentation of the formwork wall 2 added.
  • the indentation of the formwork wall 2 can, however also have other cross-sectional shapes, for example be triangular.

  • a receptacle 18 from the top of the Concrete base 13.4 is accessible a receptacle 18, but made of concrete permeable material was made, for example the material of the formwork wall 2, so that concrete can pass through when filling the cavity 2a and forms a rough surface inside the receiving sleeve 18, on which concrete or can anchor another filling compound well if the into the re
  • component 9 can be manufactured like the usual semi-finished parts of ceiling panels 19 are used, that is, the concrete part 9 is with the base plate 9a placed on the prepared surface, if necessary, to secure the Immediately provide employees with a fall protection device, the railing posts of which in the receptacles 5 can be inserted, provided with a formwork can also be attached to the fasteners 3, optionally with additional attachments and with in-situ concrete up to the predetermined thickness D of the finished, only poured in dashed lines indicated ceiling plate 19, the concrete base 13 should normally no longer protrude above the ceiling panel 19 and if necessary are covered with concrete.
  • the most diverse fastening elements are arranged in the formwork part, more than two or only one fastening element can be provided per formwork part his. So it is also possible, for example, screw blocks in the holding rails made of wood or plastic, which then slide over the slot or openings are accessible.
  • the individual fasteners can be on the most varied Sides of the formwork part appear and any desired orientation, horizontally, vertically or obliquely, for example a holding rail with a horizontal slot also run parallel to the base plate and designed to attach a component to be embedded in the ceiling as a ceiling become.
  • Receptacles can possibly also on the sides of the concrete element or the ceiling and not only on its top be appropriate.
  • the holding rail or the receptacle can be the most varied Have cross sections, e.g. B. round, oval, rectangular or triangular his. Under certain circumstances it is also possible to make the formwork wall impermeable to concrete Manufacture material when the power transmission is reduced is not a problem.
  • the formwork part according to the invention is also not only for the described, prefabricated semi-finished parts can be used for ceiling production, but can also be used for other concrete parts that are finished in one go be useful, especially when it is necessary to the mutual position of two to make one or more fasteners precisely identifiable and when casting to be maintained exactly with concrete. This is with the invention, with a Formwork wall to protect the formwork part provided with fastening elements much better possible than with simple pouring into concrete.
