Definitions

  • Reinforced concrete component The invention relates to a reinforced concrete component and to an arrangement of reinforced concrete components.
  • connection methods are used to connect the reinforced concrete components together.
  • a known method is to equip the reinforced concrete components to be connected with a connection reinforcement, to overlap or otherwise connect them in a potting area arranged between the components and then to fill the potting area with concrete or mortar, after which a viable connection is created.
  • the disadvantage here is that it takes several days or even weeks, due to the curing process, until the connection has the required load capacity. This leads to an extension of the construction period. Under certain environmental conditions, such as heat or cold, it is even such that such compounds are possible only with the use of complex and time-consuming additional work.
  • anchor elements made of steel are integrated in the reinforced concrete components to be connected. As part of an assembly, the components can then be connected to each other by means of screw or welding lugs.
  • the disadvantage here is that only the smallest structural tolerances are allowed.
  • a reinforced concrete component according to the invention has at least one connecting portion for connecting the reinforced concrete component to a further reinforced concrete component and is characterized in that the connecting portion has a wood-like nature, so that connecting elements from the field of wood technology for connecting the reinforced concrete components in the connecting portion can be arranged.
  • the reinforced concrete component according to the invention has the advantage over the prior art that it is very insensitive in terms of construction inaccuracies and can easily and quickly connect easily and quickly with other reinforced concrete components by means of known fasteners high quality.
  • a connecting section having a wood-like nature is generally understood to mean those connecting sections which have a texture similar to that of wood or a wood-based material.
  • the nature of the connection section according to the invention does not have to correspond exactly to that of wood or a wood-based material. It is therefore sufficient according to the invention, if the connecting portion is formed so that it can receive known from wood technology connecting elements. Wood screws or nails, full-thread screws or dowels, which are incorporated as intended in the wood-like material, are among the known connecting elements of wood technology.
  • the connecting portion may be formed according to the invention of wood or a wood material.
  • wood-based material such materials are understood to be produced by crushing wood and then joining the structural elements according to the invention.
  • the connecting section need not be made of wood or a wood material. It is sufficient that its material properties are such that they can absorb known from wood technology fasteners. These include e.g. Connecting sections of resin-bonded chipboard materials or also of plastics (for example on nylon basis). The use of plastic offers the advantage that the connecting sections are weather-resistant, shatter-proof, easy to process and have a high breaking strength. Overall, such a long durability can be ensured.
  • For the connection section may advantageously be used a recycled plastic.
  • the connecting section consists of a hydrophobic or hydrophobized material.
  • the connecting portion has a layer structure.
  • the connecting section is composed of several wood or wooden material layers. It may be in the material of the connecting portion to plywood, in which the adjacent layers preferably have a divergent fiber profile.

  • the profiling is wave-shaped and / or trapezoidal.
  • the profiling can also be designed in the manner of a tongue and groove joint.
  • all sides of the connecting portion adjoining the concrete are profiled. Optimal transmission of shear forces can thus be ensured. It is conceivable that at least the surface of the connecting portion, which adjoins the concrete, is structured.
  • the connecting portion may have a recess at least partially on at least one of its outer sides.
  • the outer side is an environment facing, ie not facing the concrete surface to understand. If the connection section has a depression, then a connection element, for example a metal sheet or even a nail or screw head, can be arranged in the depression and so does not protrude beyond the reinforced concrete component. A flat surface of the reinforced concrete component can be produced in this way.
  • the connecting portion is arranged in the reinforced concrete component, that five of its six sides are surrounded by concrete. Only one surface or side of the connection section can be seen.
