Definitions

  • the present invention relates to a formwork for cross-sectionally polygonal concrete supports with an outer support tube which is round in cross-section and suitably preformed molded parts inserted therein.
  • the desired polygonal cross-section is immediately limited and determined by a correspondingly shaped tube.
  • the object of the invention is in particular to provide a simple and inexpensive formwork for polygonal concrete columns. This object is achieved by a formwork with the features of claim 1.
  • the formwork according to the invention is accordingly characterized in that that the moldings mentioned consist of a foamed material, directly limit the polygonal cross section and essentially fill the entire space between the polygonal cross section and the inner wall of the support tube. An additional tube is not required.
  • the required molded parts can e.g. cut out of blocks with sufficient accuracy using modern laser cutting technology. Expensive injection molds are therefore also not required. This type of production is also very flexible with regard to the desired shapes and their size, since the shapes in modern computer-controlled laser cutting machines can be varied by simple program changes.
  • the drawing shows cross sections of or end views of formwork according to the invention.
  • the formwork shown differ on the one hand in terms of the polygonal cross section and on the other hand in the shape of the respective molded parts.
  • the outer, round, preferably made of paper or cardboard support tube is designated by 1.
  • shaped parts 2 of identical shape are inserted into the support tube 1 to achieve a square cross section for the concrete column to be concreted.
  • the shaped parts 2 essentially have the shape of circular sections in cross section and meet at the corners of the square cross section.
  • the abutting surfaces of the molded parts 2 are, at least partially, aligned radially with respect to the longitudinal axis of the support tube 1.
  • triangular strips 2.1 are still formed on one side on the molded parts 2.
  • Fig. 2 corresponds essentially to that of Fig. 1, only here to achieve chamfers at the four corners essentially double-T-shaped profile strips 3 are provided, which with their longitudinal webs between the adjacent, here completely radially aligned long sides which are again pushed with 2 designated moldings.
  • This embodiment has the advantage that the profiled strips 3 are pressed into the corners by the pressure of the concrete during concreting and close the gaps present there.
  • a square cross section is delimited by four shaped parts 4 of the same shape, which collide centrally on the flat side surfaces of the cross section.
  • Fig. 4 shows corresponding molded parts 4, which, however, are mutually engaged on their abutting surfaces by a type of toothing. Instead of the toothing, a tongue and groove connection could also be provided. Due to their mutual engagement, the molded parts are better fixed in the support tube. Furthermore, the penetration of concrete into the gap between the molded parts 4 is hindered. It goes without saying that a mutual interlocking of the molded parts with one another is possible and useful not only in the specific embodiment of FIG. 4 but also in other embodiments.
  • molded parts 5 In the embodiment of FIG. 5, only two molded parts 5 are provided.
  • the abutting surfaces of these molded parts run at an oblique angle to the flat side surfaces of the again square cross section and end in the middle on two opposite of these side surfaces.
  • the molded parts 5 could of course also be subdivided into a total of four molded parts, or that conversely, for example, two of the molded parts 2 or 4 or the molded parts described below could be combined to form uniform molded parts.
  • FIG. 6 shows a top view of one of the two end faces of the molded parts 2 from FIG. 1, on which webs 2.2 are provided. Corresponding grooves should be provided on the opposite end faces of the molded parts 2.
  • the webs and grooves serve to bring molded parts inserted in the longitudinal direction one after the other into longer support tubes 1 on their adjoining sides of the string. It goes without saying that such webs and grooves can of course also be provided for all other types of molded parts.
  • molded parts 6 are inserted into the support tube 1 to achieve a square cross section, the shape of which is selected such that the gaps between their adjoining abutting surfaces close automatically when concreting under the pressure exerted by the concrete.
  • the chamfers provided at the corners of the square profile are used here, the abutting surfaces of the molded parts being 6 extensions of these chamfers.
  • the molded parts can easily have some play against each other, which considerably facilitates insertion into the support tube 1.
  • the molded parts 6 can even be slightly removed from the circular shape in their areas designated by 6.1.
  • the game artificially generated in this way can be compensated for by excess material in the opposite areas denoted by 6.2.
  • FIGS. 8 to 10 The concept of the exemplary embodiment from FIG. 7 is transferred in FIGS. 8 to 10 to a hexagonal, an octagonal and a triangular cross section.
  • the respective molded parts are designated 7, 8 and 9.
  • FIGS. 11 and 12 a square or a rectangular cross section is delimited by two pairs of different molded parts 10, 11 or 12, 13.
  • the molded parts 11 and 13 are inserted here in the manner of wedges between the molded parts 10 and 12, respectively.
  • a square cross section is delimited by four identical shaped parts 14, which have the shape of circular sections in cross section and which do not adjoin one another in the corners of the polygonal cross section, but instead have a certain mutual distance there to achieve chamfers and the inner wall of the support tube leave uncovered.
  • At least the inner surface of the molded parts delimiting the polygonal cross section can be covered with a water-impermeable, preferably self-adhesive plastic film. If you leave the film on the long sides of the molded parts on both sides protrude, the protruding film strips can be glued to seal the gaps between the molded parts.
  • the film strips in the corners of the polygonal cross section on the inner wall of the support tube, where it is not covered by the molded parts can be glued overlapping. The latter is shown in FIG. 14, which shows an enlarged representation of the upper right corner framed by a circle in FIG. 13. The film is designated 15 in FIG. 14.
