Definitions

  • Arrangement for integration into a component preferably a gradient component
  • the invention relates to an arrangement with two shaped bodies, at least one hollow body and at least one reinforcement structure.
  • the arrangement is used in particular for integration into a component, preferably made of concrete, reinforced concrete, mortar or clay.
  • the component can e.g. B. be a gradient component, in particular a mesogradient component.
  • Usual solid components from e.g. B. concrete, mortar or clay are characterized by a homogeneous materiality within the component. Although it is known that these components are very inhomogeneously loaded on the inside when subjected to static and/or dynamic stress, parts of the material in the interior of the component are only subject to low stress or are not required to absorb these stresses, there have only been a few approaches to the component interior through specifically generated Structuring cavities in such a way that a reduction in the weight of the component and, related to this, a reduction in the consumption of resources, the energy required to manufacture the component and the emissions released during the manufacture of the component can be achieved.
  • One approach is gradient components.

  • the reinforcement required to absorb the tensile forces occurring in a concrete component currently typically reinforcement made of rod-shaped structural steel or reinforcement mats made from it, is usually laid parallel to the component surfaces for reasons of simpler assembly. With the resulting geometric structure of the reinforcement, the bar axes of the reinforcement bars usually deviate from the tensile trajectories within the component.
  • Trajectories are lines with the same main stress direction. The amount and sign of a principal stress can thus change along a trajectory.
  • Tension trajectories are understood to mean in particular those lines which are lines of the same main stress direction along which the stress does not change its sign but is always under tension and along which the magnitude of the tensile stress is ideally largely constant.
