Definitions

  • Such slab formwork in which the main beam and the secondary beam form a support grid arranged in two levels are from FR-A-1532639 known.
  • the structure known from this document enables an arrangement the secondary beam in certain grids.
  • the invention has for its object a platform or stage of the beginning to create the type mentioned, in which an optimal subcarrier definition is realized with high variability of the location of the carrier.
  • DE 1434365 A proposes the attachment of flat board-like supports, which in the Level of the control panels are provided by means of pin-like projection elements on stands.
  • the main beam / secondary beam can be fixed with little Create workload, usually by simply putting on the secondary beam.
  • the form-fitting determination prevents a shift 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 bearing surface plane.
  • the execution is such that even moments that are about Axis standing perpendicular to the bearing surface plane, form-fitting be included.
  • the platform or stage is very variable because of secondary beams in a variety of selectable locations on a main beam under consideration can be stored and because even with a secondary carrier considered under a variety of digits of its length for bearing on one Main carrier can be chosen. This variability is of great importance that the platform or stage, especially the ceiling formwork, adapted from standard components depending on the specific task can build.
  • 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 In addition to the carrier.
  • short bolts made of plastic or metal as projecting elements on the carrier concerned (main carrier or secondary carrier) 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.
  • the Short bolts are attached in openings of the carrier concerned.
  • the main carrier in question and / or the secondary carrier in question has smaller openings therein attached protruding elements and larger engagement openings having.
  • 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 in question and / or the secondary beam in question consisting of 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 both for 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 side beams that the bumps between adjacent panels - seen in plan view - approximately coincide with the longitudinal center line of the secondary beam. At 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.
  • At least one considerable part of the uprights / main girder support points positive determination between the relevant post and the the main beam concerned against forces in any direction in one direction Plane which is perpendicular to the longitudinal direction of the post and through which leads support point provided.
  • This positive definition can, but does not have to, according to described main girder / secondary girder definition principle take place, in particular by the engagement of protruding elements in Openings can be formed, the protruding elements from an upper The storage area of the upright in question protrudes and the Openings in a lower storage area of the main beam in question are trained or vice versa.
  • At least a significant part of the Auxiliary support / plate support points form-fitting determination between the secondary beam in question and the plate in question against forces of any direction in the support surface plane is provided.
