Definitions

  • the invention relates to a reinforcement for Schalalplatten, a process for their preparation and a Abschalungsplatte with such a reinforcement according to the preamble of claims 1, 7 and 8.
  • ceiling edging is used to limit the volume to be filled with concrete.
  • These can include, for example, formwork panels or wooden boards, which are removed after concreting the ceiling.
  • lost ceiling edge shutters are, for example, prefabricated concrete slabs which are fastened to the slab formwork by suitable means. They combine with the liquid concrete of the ceiling and form the face of the ceiling tile. The concrete slabs provide the desired benefits in terms of quality and strength.
  • foam boards instead of prefabricated concrete elements foam boards as a lost ceiling edge formwork and at the same time as insulating elements to prevent cold spots.
  • Such plastic plates usually have a variety of supports with a small mutual distance be supported to prevent breaks or deformation due to the low intrinsic stability.
  • lost formwork When using lost formwork as intermediate formwork can - depending on the type of shuttering panels - the insufficient stability and / or high installation costs and / or the large plate thickness adversely affect.
  • large tensile and / or compressive forces usually act in the area of adjoining ceiling sections.
  • Lost intermediate formworks should therefore be as dimensionally stable as possible.
  • such networks must be kept because of the low intrinsic stability by a large number of stable frames and brackets or by a variety of additional bracing with small mutual distances.
  • the nets are pierced by the protruding reinforcing bars. Often this results in larger cracks that need to be repaired, for example, with special adhesive tapes.
  • the creation of such intermediate formwork is complex and expensive. Even small damages can lead to bursting or tearing of the nets when concreting.
  • Shuttering devices typically include one or more planar shuttering plates 5 for laterally limiting the volume to be filled with concrete.
  • a wall 1 made of concrete or bricks can be seen on a floor or ceiling slab 3 is to be concreted.
  • a shuttering plate 5 also referred to as a plate, placed on the wall 1 and held by means of brackets 7, which are fastened with nails 9 on the slab formwork 11.
  • the slab formwork 11 is held by supports 13 at the desired height.
  • the shuttering plate 5 is designed as a lost element, ie the shuttering plate 5 connects after filling the liquid concrete for the ceiling plate 3 with the concrete and the surface 15 forms the end face of the finished ceiling panel 3.
  • a formwork panel 5 is for example from EP-A1-0927796 known.
  • FIG. 2 shows another Abschalungsplatte 5 with reinforcements 17 to increase the dimensional stability and protection against mechanical damage.

  • flat reinforcing mesh are completely embedded in a lightweight construction material such as polystyrene or another foamed mass of plastic or sand and additives.
  • the reinforcement 17 is invisible and has no influence on the surface condition of the panel. In intervals of the reinforcement 17 may be provided with small distances vertically extending holes or channels 19, which allow insertion of the headband 7 from below and ensure the same.
  • the shuttering plate 5 may have a smaller thickness in the lower and possibly also in the upper region, so that the stirrups 7, as in FIG FIG. 1 represented, leave the shuttering plate 5 side and can be aligned exactly horizontal.
  • the reinforcement 17 is formed as a multi-folded, perforated reinforcing plate.
  • This can for example be made of sheet metal by bending operations or of an extruded plastic profile and is not or only partially, ie not completely, embedded in the interior of the plate 5.
  • two angled portions 23 overhang the inner surface 25 of the reinforcing plate. These angled portions 23 are with aligned holes 27 provided, through which the vertical legs of the headband 7 are inserted from below.
  • aligned holes 27 In parallel to the inner plate surface ( FIG. 1 ) extending areas adjacent to the sections 23 openings 29 are mounted in the reinforcing plate. These cause a close connection with the plastic compound or the lightweight building material (matrix) on both sides of the reinforcing plate.
  • shuttering panels 5 can also be designed as reusable panels which - like the ceiling formwork 11 - are treated with an anti-adhesive agent prior to concreting and are removed again after the concrete has set.
  • FIG. 4 shows an example of a cross section in the region of an intermediate formwork for creating a ceiling portion, wherein the shuttering panels 5 as in the ceiling edge Abschalung in FIG. 1 are formed as lost plates.
