Definitions

  • Formwork elements for cladding concrete construction using polystyrene granules are conventional foamed as a starting product in molding machines, which includes a water treatment system, a fluid bed dryer, a rotary valve, a steam generator, an energy supply system, very large raw material silos, a pre-foamer, an automatic loading system

  • metal bars as spacer
  • DE 2 349 601 A1 describes a method for producing formwork elements for the shell concrete construction method using hard foam plastic blocks is known, with prefabricated blocks, individual inner and outer walls with horizontal undercut, longitudinally displaceable, non-positive, integrated height grids positive and negative as well as slots for receiving in the final process step Plastic connecting webs are provided, which the inner and outer walls connect the formwork elements to each other stably.
  • the height grids are arranged in such a way that the joints cannot be moved during the construction process becomes.
  • Another disadvantage of this solution is the fact that the molded foam Part is not demoldable.
  • This solution uses connecting bars that run all the way to the outer edge the inner and outer walls of the formwork element are arranged. Are do not undercut the vertical grid, so that there is a risk of floating when pouring concrete consists. Another disadvantage is that the spacers are arranged on the outside are.
  • the object of the invention is to provide a method for the production of formwork elements to propose the sheath concrete way with the inexpensive optimal conditions for the connection of inner and outer formwork as well as in height and there is no need for formwork for future plaster beams.
  • the method according to the invention provides for the use of styrofoam blocks which are in a form cutting machine are inserted and fixed and then in an outside and Internal formwork of the prescribed thickness of the wall can be cut, such that the outer as well as the inner wall of the formwork element has such a rough surface have a later plaster application can be done without a plaster base, at the same time cutting slots for connecting webs in the outer and inner formwork, the connecting webs after dividing the block into individual formwork elements and their positioning into the formwork elements and after joining the inner and outer formwork a multiple point connection over the entire area of the inner and outer formwork form, and in the inner and outer formwork positive and negative vertical grid can be cut or milled with an undercut, the horizontal when installed allow later dismantling in the height of the formwork assembled, prevent floating when pouring concrete.
  • Different heights of the formwork elements for example for compensating elements.
  • Different strengths of the Formwork elements can either be changed by changing the wall thickness of the formwork elements, or by extending the connecting webs and the associated increase in the distance between the inner and outer formwork to reach.
  • a block of styrofoam is inserted into a form cutting machine and fixed. Then are the walls to the prescribed thickness of the wall using a Cutting device cut. This creates a roughness of the surfaces, which later pouring concrete onto its surface and transfers the plaster base function takes over. At the same time, the slots for the connecting webs are cut. As Cutting device come with glowing cutting wires, comparable to a saw frame for use.
  • the slot shape is preferably T-shaped.
  • height grids are milled positive and height grids negative are milled with an undercut and / or cut that a later disassembly in the formwork assembled allow, but prevent floating when pouring concrete.
  • the block is then divided into individual walls by conveyor belts and switches and these are positioned in pairs in such a way that by manual or mechanical Push the connecting webs, preferably plastic recycling webs, into the for this provided slots a multiple point connection over the entire surface of the External and internal formwork is created, which has sufficient strength as well as stability of the finished formwork element consisting of inner and outer formwork.
  • Different wall thicknesses can be used for the length of the connecting webs the concrete can be realized.

  1. Procédé de fabrication d'éléments de coffrage pour la construction en béton coulé recourant à des blocs de polystyrène introduits et fixés dans un automate de découpe avant d'être coupés en coffrage intérieur et extérieur d'épaisseur de paroi prescrite, caractérisé en ce que
    les éléments de coffrage sont coupés de telle sorte
    que les parois intérieure et extérieure des éléments de coffrage présentent une surface d'une rugosité telle qu'une application ultérieure de crépi sans support est possible ;
    qu'une découpe de fentes pour des traverses de liaison est en outre simultanément exécutée dans le coffrage intérieur et extérieur, lesdites traverses de liaison étant posées dans les éléments de coffrage après division du bloc en ses différents éléments de coffrage et positionnement de ceux-ci, pour former, après assemblage du coffrage intérieur et extérieur, une liaison ponctuelle multiple sur toute la surface du coffrage intérieur et extérieur ; et
    que des crans sur hauteur, positifs et négatifs avec contre-dépouille et disposés horizontalement, sont découpés ou fraisés dans les éléments de coffrage intérieur et extérieur à l'état monté, lesdits crans permettant un démontage ultérieur d'éléments de coffrage assemblés en hauteur, tout en empêchant leur flottement lors du coulage du béton.
