Definitions

  • a marking element, a textile-reinforced concrete with marking element and a method for producing a textile-reinforced concrete with marking elements are described.
  • a reinforced concrete has reinforced steel reinforced concrete the advantage of lower weight and a lower height with the same load capacity.
  • textile mats or fabrics are covered with liquid or viscous concrete and then cured.
  • an alignment of the textile reinforcements during manufacture must be ensured.
  • spacers on a base, for example, a formwork and then attach a textile reinforcement to the spacers. This ensures that the textile reinforcement is completely surrounded by concrete.

  • Such a spacer for insertion into a manufactured with a base material component with integrated textile reinforcement is, for example DE 10 2012 025 629 A1 known.
  • An essential aspect in the production of textile-reinforced concrete is the introduction of liquid or viscous concrete during manufacture.
  • textile-reinforced concrete is distinguished from reinforced concrete in that lower heights of concrete elements can be achieved. Accordingly, less concrete is used, with the difficulty arises to realize a precise quantitative introduction.
  • the finished concrete part has a defined height.
  • a formwork can be used which has the exact height. Excess concrete can then be smoothed and removed.
  • the object is to provide a textile-reinforced concrete, a method for producing a textile reinforced concrete and an aid therefor, which allow a formation of a textile-reinforced concrete with a defined height.
  • the marking element can be used to indicate a filling level for a liquid or viscous concrete, which is introduced, for example, in a formwork.
  • the marking element can be used both in the use of liquid and viscous or conventional concrete. Conventional concrete may spread by shaking (compacting) in the surface.

  • the second planar sections of the marking elements then lie in one plane and define the maximum filling height for the concrete. Because they extend over a flat area, a simple indication for the introduction of concrete is provided. For example, in the case of punctiform elevations which indicate a maximum height, reaching the maximum fill level would be much more difficult to discern.

  • marking elements 30 can also be stacked on top of one another, wherein a third part is placed on a second part 16 of a marking element 10, the second area of which has a smaller diameter than the second section 20.
  • marking elements 10 are used, with a textile reinforcement being held.
  • the distance of the textile reinforcement to the opposite side walls of the textile-reinforced concrete 30 or other precast concrete elements, which are not shown in the figures, can be defined by the selection of the heights of the spacers 18 and the spacer elements 14.
