Definitions

  • the invention relates to a method as described in the preamble of claims 1, 7 and 8.
  • Formwork for series prefabricated parts made of concrete are usually very stable and expensive to manufacture because of the high production numbers. This is particularly true for turnout sleepers manufactured one after the other in the fitted bed. These also place very high demands on the dimensionally accurate position of the built-in parts.
  • the built-in parts are therefore fixed in bores in the formwork, which are measured extremely precisely.
  • the built-in parts - dowels or pipe sleeves for the rail fastening screws - are on the top of the sleepers.
  • the top of the threshold lies in the formwork on the formwork floor.
  • the base plate thus serves as a template for the installation of the built-in parts.
  • a drilling grid is often used for large series.
  • the templates to be produced for each type of threshold therefore have little influence on the costs for the individual threshold. With a small number of sleepers being manufactured, the cost of the floor panels serving as templates for the built-in parts can jeopardize the economics of manufacture.
  • the invention has for its object to develop methods according to which a floor panel of a prestressed bed formwork for the production of small series of switch sleepers made of concrete with different arrangement of the built-in parts can be used repeatedly.
  • the object is achieved by the measures specified in the characterizing part of claims 1, 7 and 8.
  • Refinements of the methods are specified in subclaims 2 to 6 and 9 to 17. Claims 1, 7 and 8 describe three solutions to the problem.
  • Claim 1 describes a simple solution, according to which the floor panel is drilled on site or after removal for the production of a further threshold type with the associated hole combination. This process still requires considerable wage costs.
  • the holes not used spans the thin cover according to the invention from a tough material due to the selected thickness and strength under concrete pressure without damage. It is newly manufactured for each new type of precast element and can be manufactured with little effort.
  • the markings for the positions of the built-in parts can be drawn on it with computer help, so that the cover can already serve as a template for the holes.
  • the production of such a cover from thin sheet metal, plastic or synthetic paper is considerably less expensive than a new production of the steel floor plate for the formwork.
  • the floor panel is drilled from the outset with the bores of all types of prefabricated parts for which it is to be used, in one operation - if possible electronically program-controlled - before installation in the formwork and by grafting - for. B. temporarily closed by plastic or by filling.
  • the bores in the floor panel required for the respective production of a certain type of sleeper must be found, opened and filled with holding devices for the built-in parts - in this case the pipe sleeves.
  • This searching can be done according to claim 10 with search templates or also by electronically program-controlled devices.
  • the method according to claim 7 avoids later drilling work on the floor panel, but limits its use to the types of sleepers with whose hole combinations it is drilled.
  • a method according to claims 8 and 9 is completely independent of a prior definition of the threshold types.
  • the floor panel is bored in a fixed - grid - expediently on the central axis and / or axes parallel to it and at equal intervals - with holes or a continuous slot provided.
  • the application of the method according to claims 8 and 9 therefore requires u.
  • U. on the rib plates small deviations of the holes from the central axis, namely to the extent that during the manufacture of the threshold no grid hole of the floor panel can be directly covered by a hole arranged in the central axis of the rib plate.
  • the length of several finished parts or the entire fitted bed can be according to the method according to claims 8 or 9 be covered by formwork sheets according to claims 16 and 17, respectively.
  • the parking devices are placed on the floor panel.
  • the method according to claims 8 and 9 enables automation of the installation of the parking devices and the built-in parts in the formwork.
  • turnout sleepers 2 are produced in series between side formwork on floor panels 3. Thresholds arranged one behind the other are delimited by parking devices 9 in the formwork. Bores 4 fix the position of built-in parts 5 in the switch sleepers 2 in the floor plates 3.
  • Figures 2 and 3 show a cover 6 of the floor panel 3 according to claim 1, on which the associated new positions of the built-in parts are marked.
  • This cover 6, for example glued on, covers the bores 7 of the floor panel 3 from previous uses.
  • the holes 9 of the hole combinations for the positions of the built-in parts of the new use are made congruently in the base plate 3 through the cover 6.
  • the bottom plate 3 according to claim 7 in the example shown in Figures 4 and 5 has the holes A1-A m , B1-B n , C1-C r , etc.
  • the floor panel 3 only covers the length of a threshold in the fitted bed. Parking devices 9 are inserted between the floor plates 3.
  • the search template 10 is adjusted with the aid of alignment marks 11, which are marked both on the base plate and on the search template.
  • the holes B1-B m belonging to the threshold type B are indicated in the vicinity of the other holes A1-A m , C1 C r etc. and are particularly marked. They can thus be clearly found in the vicinity of the other bores and the plugs can be removed from these bores and the holding devices for the tube sleeves can be installed.
  • FIGS. 6 and 7 show a continuous base plate 21 provided with bores 25 in a fixed grid.
  • the bores 25 are arranged in the central axis 26 at an equal distance from one another.
  • a search template 14 is adjusted on the base plate 21 with the aid of alignment marks 15, which are marked both on the base plate 21 and on the search template 14.
  • the holes K1-K m belonging to the threshold type K are indicated in the vicinity of the other other threshold types associated holes I1-I m , L1-L r etc. and are particularly marked. They can thus be found out clearly from the other bores, freed of the sealing plug and filled with tube sleeves or holding devices for the installation of the tube sleeves. In the same way, the holes 22 required to fix the parking devices 9 are sought.
  • the outline 16 of a specially drilled rib plate 17 is entered according to claim 15.
  • the bores 23, 24 are not on the central axis 18 of the ribbed plate 17, but by the dimensions 19, 220, which differ as a rule, except for the axis, in order to come into congruence with the associated grid bores K 1, K 2.
