  • the main support / secondary support can be determined create little work, usually by simple Put on the secondary beam.
  • the positive determination prevents a displacement of the secondary beam in the longitudinal direction of the main beam, in the longitudinal direction of the secondary beam and in all composite Directions in the storage area level.
  • the execution is preferred so that even moments that are perpendicular to the Axis standing on the bearing surface plane, positively incorporated will.
  • the platform or stage is very variable because of secondary beams a large number of selectable positions on a main beam under consideration can be stored and because also with one considered Subcarrier under a variety of places its length for that Support on a main beam can be selected. This Variability is of great importance for having the platform or Stage, especially the slab formwork, depending on the concrete Can set up the task from standard components.
  • openings is not just that Openings that are surrounded by material all around, but also openings that are open to one side, e.g. a Recess at an edge of the bearing surface of the main beam or the Secondary carrier.
  • short bolts made of plastic or metal as projecting elements, on the carrier concerned are attached.
  • the carrier concerned main carrier or secondary carrier
  • alternative versions are quite possible possible, in particular by bent from the storage area level Material areas of the carrier. It is particularly favorable if the Short bolts are attached in openings of the carrier concerned.
  • the main carrier in question and / or the subcarrier in question has smaller openings therein attached protruding elements and larger engagement openings having. With this training you can be the main carrier and First create secondary beams in the same way with openings and in one subsequent manufacturing step by attaching the short bolts Create beams with protruding elements.
  • the person concerned Main beam and / or the relevant secondary beam made of folded Sheet, preferably sheet steel, are made.
  • the openings are preferably stamped before folding. So the straps can be manufacture very efficiently. The construction is considerably cheaper than that Made from aluminum.
  • the main carrier concerned and / or preferably consists secondary beam in question from two essentially U-shaped profiles, those with their backs facing each other and at a distance from each other are connected.
  • the carriers get - in top view considered - an increased width, which is the main beam for
  • the cheap support of secondary beams is an advantage as well the secondary carrier to create increased security against Tipping over when erecting the platform or the stage.
  • the two profiles are preferably by screw connections connected to each other and by spacers, preferably made of Plastic, kept at a distance. This ensures a particularly rational Manufacturability.
  • the relevant Main carrier and / or the relevant secondary carrier openings are preferably in the vertical double web of the relevant Main carrier and / or the relevant secondary carrier openings provided, preferably in the form of one or more rows along the Carrier. Again, the provision of the openings in the Pitch particularly preferred.
  • the openings described can for a whole host of functions are used, in particular Fastening a nail bar between the two profiles, attachment of secondary structures such as parapets and attached walkways and much more.
  • the structure of the carrier from two spaced profiles has in particular also the following advantage, which is very important in practice.
  • the plates will be placed on the secondary beams that the bumps between neighboring plates - seen in plan view - approximately coincide with the longitudinal center line of the secondary beam.
  • the Concreting often runs through the plate joints and this no longer contaminates the wearer, but simply runs in between down through the two half beams.
