Definitions

  • the invention relates to a formwork for the vertical production of flat precast concrete elements, with at least two scarf walls, two Soabstellem, a floor rests and a standoff and at least one provided in the lower formwork area filling connection for concrete.
  • Formwork of the type mentioned have become known from PCT / EP 2008/054484 and EP 1 923 185 A1 and EP 1 923 527 A1 (DE 10 2006 053 552 B3). They can be used to produce flat prefabricated concrete elements by placing the concrete from below. In the attempt to produce three-layer wall elements, which consist of a concrete facing layer, an insulating layer and a concrete base course, in a single operation, the previous formwork have failed. As a result of the different thicknesses of the attachment layer and the base layer, irregular filling of the interior of the formwork connected to a warp of the insulating layer occurred regularly. Moreover, segregation of the commonly used self-compacting concrete occurred, ie one concrete layer was ultimately finer grained than the other and, in addition, flow streaks were visible on the surfaces of the finished products. The reject rate was correspondingly high.
  • the aim of the invention was and is to perfect the known formwork to the extent that it can be produced without errors in a single operation in high quality multi-layered, at least two separate concrete layers having wall elements.
  • the vertical, bottom-side inflow should also be related to the fact that now no segregation of coarse and fine grain occurs.
  • the baffle plate whose width corresponds to the distance of the two concrete layers to be produced, ie the thickness of the insulating layer, prevents or minimizes buoyancy so that damage to the insulating layer is stopped from below as the formwork is filled up.
  • the recess formed by the baffle plate must be foamed at the lower edge of the insulating layer after demoulding the wall element with an insulating material, for example with polyurethane.
  • FIG. 1 shows a schematic cross-section along the line 1-1 of FIG. 2 through a formwork according to the invention with already incorporated therein set insulating and reinforcing element and Fig. 2 is a longitudinal section along the line H-II of FIG. 1st
  • the formwork according to the invention has two formwork walls 1, two toabsteller 2, a Bodenabsteller 3 and a height adjustment 4.
  • a filling connection 5 for concrete is provided on one side, from which a filling channel 6 emanates, which opens vertically into the Bodenabsteller 3.
  • the orifice 7 has a width which corresponds to the distance between the two concrete layers to be produced, ie the thickness of the insulating layer 8 of an insulating and reinforcing element inserted in the formwork in the course of the manufacturing process.
  • This insulating and reinforcing element has, for example on both sides of the insulating layer 8 still connected to this wire grid 9, which represent the reinforcement of the two concrete layers 10 and 11 to be produced.
  • the shown, thinner concrete layer 10 corresponds for example to an attachment layer, the thicker concrete layer 11, for example, a support layer. Both layers 10 and 11 are formed but only by filling and hardening of self-compacted concrete.
  • the orifice 7 is entirely covered by a baffle 12, the width of the width of the insulating layer 8 corresponds.
  • baffle 13 In Jetkanal 6 a baffle 13 is installed, which supports the deflection of the inflowing from the filling port 5 concrete in a vertically upward flow.
  • each compensation channels 14 are kept free at the Soabstellern 2.
  • risers 15 are provided.
  • both concrete layers 10 and 11 (whose reference lines are shown by dashed lines) are filled up uniformly by utilizing the physical principle of the communicating volumes.
  • the compensation channels 14 the concrete between the layers 10 and 11 can flow and thus contribute to larger differences in thickness of the two concrete layers 10 and 11 for an additional compensation of the level in the two layers.
  • excess concrete emerges through the risers 15. After a given curing time, the wall element is de-energized, and the concrete plugs created by the equalization channels 14 are removed.

Abstract

L'invention concerne un coffrage pour la fabrication verticale d'éléments préfabriqués plats en béton, comportant au moins deux parois de coffrage (5) pourvues de deux éléments support latéraux (2), d'un élément support inférieur (3) et d'un élément support supérieur (4), et au moins un raccord de remplissage (5) pour du béton, prévu dans la partie inférieure du coffrage. Pour la fabrication d'éléments préfabriqués plats en béton, un canal de remplissage (6) aboutissant verticalement dans l'élément support inférieur, s'étend à partir du raccord de remplissage (5), la largeur de l'embouchure (7) correspondant essentiellement à l'écart entre les deux couches de béton (10, 11) à fabriquer, et toute l'embouchure (7) étant recouverte par une tôle d'impact (12) de même largeur que l'embouchure, disposée à un espace prédéfini.
