Definitions

  • the invention relates to a circulation formwork as described in the preamble of claim 1.
  • Such formwork for prestressed concrete sleepers is described, for example, in the magazine “Bundesbahn” No. 10/1981 p. 844, 3rd column, 2nd paragraph in the article "30 years of concrete sleepers at the Deutsche Bundesbahn". Because of their stiffness required for applying the prestressing, they are very complex and can only be used for a certain finished part - a certain threshold. The high cost of formwork renders the process uneconomical for special sleepers with small quantities, such as those that occur with industrial siding connections or with small municipal or private railway companies.
  • a two-part threshold formwork is known from French published patent application 26 44 722 A1.
  • the lower part covers the side and bottom surfaces of the formwork.
  • a frame is slipped over this, which serves as a tensioning frame and whose tensioning latches simultaneously form the end faces of the threshold formwork.
  • the invention has set itself the task of developing the known sleeper constructions so that within the limits that the tendon abutments set for the length of the finished part, any length of finished parts can be produced without incurring considerable molding costs.
  • the formwork element can be economically manufactured because it is not stressed by the high prestressing forces.
  • casting processes of shaped bodies for example made of wood, and also concrete and plastic can be used as materials, as a result of which the manufacturing process is considerably cheaper, even for relatively complicated shaped bodies.
  • the circulating formwork according to the invention is formed by the frame 1 and the formwork element 4.
  • the frame 1 comprises at the head ends the abutment bars 2 and the longitudinal posts 3, which keep the abutment bars 2 at a distance against the tensioning forces of the tensioning wires 6.
  • Each frame 1 encloses with bars 2 and posts 3 at least one field (in the examples shown there are two fields) into which a formwork element 4 can be inserted.
  • the formwork element 4 is held on the outside by the frame 1 and forms the finished part 5 with its inner contour 7.
  • 5 shows a frame 1 with bars 2 and posts 3 and devices 9 according to claim 10 designed according to claim 9 with inclined inner sides 8 and holding the formwork element 4 detachably in the frame 1.
  • an oarlock 9 is shown as a holding device.
