  • the metal meshes 223 are used by way of example in a partial area of the wood-concrete composite system in that high local stresses prevail.
  • the plastic grids 221 are anchored at about one-third of their height, with one end in the wooden member 210 by gluing.
  • the plastic grids 221 have been made such that the grid openings 222 in the wood material 210 and in the intermediate layers 230 have smaller dimensions (close-meshed) than in the concrete component 240 , thereby saving on adhesive in the anchoring in the wooden component (lower adhesive volume) and on the other to increase the intrinsic stability of the plastic grids 221 in the region of the intermediate layers 230 (no frictional lateral support).
  • the undulating shape provides, on the one hand, additional inherent stability and, on the other hand, further mechanical interlocking between the wooden components and concrete components to be joined.
  • the plastic grids 221 have in the binding region of the wooden components 210 teeth (not shown here), which ensure a mechanical fixation of the connecting elements to the setting of the adhesive.
  • the metal grid 223 are glued here, for example, with two ends in corresponding openings (here slots or channels) of the timber components and thereby provide in itself a geometrically rigid shape and at the same time a very rigid connection between the timber members 210 and the concrete components 240th
  • the metal mesh 223 have in the kerf between connecting element and wood, for example, a bead (not shown here), which prevents the adhesive from exiting.
  • the intermediate layers 230 consist here by way of example of a multilayer bitumen coating with embedded plastic film 231 and a PU rigid foam layer 232 , which was created by way of example from individually cut and laid in association panels.
  • the concrete components 240 are formed here by way of example by a constant plate 241 .
  • the concrete components 240 have reinforcements 242 in the form of welded steel meshes 243 , which for example only rest on the connecting elements 220 .
  • the concrete slab 241 further includes a localized reinforcement 244 in the form of a reinforcing steel 245 which has been laterally connected (for example, wire-knurled, not shown) prior to concreting and applying the reinforcing steel mat 243 to the securing member 220 .
  • the concrete components 240 furthermore have cavities 246 and lines 247 , which serve, on the one hand, for subsequent reinforcement and, on the other hand, for the climatic supply of the concrete components 240 .
  • the cavities 246 are used to introduce appropriate prestressing steels in order to enable a non-positive subsequent reinforcement of the concrete components 240 .
  • the position of the cavities 246 is dependent on the execution requirements and can be exemplified over, between and / or performed by the connecting elements 220 and / or 223 .
  • the lines 247 serve as an example - via a coupling with a corresponding climate control center - for the climatic supply of the wood-concrete composite system and its surroundings.
  • the wood-concrete composite system 200 was here prefabricated as an example in the factory as a precast and delivered as individual components Segmented to the site and mounted. Such prefabrication allows rapid construction of the structure without introducing additional moisture (eg mixing water of the reinforced concrete) in the wood-concrete composite system or buildings.
  • the individual wood-concrete composite systems can be used immediately at the construction site Assembly or some time later with each other and / or with other construction stages be positively and / or positively connected. That way too Create disc effects with segmented wood-concrete composite systems.
