Definitions

  • the present invention relates to a structural element for concrete structures according to the preamble of
  • Concrete structures used as ceilings, walls and beams are used in all modern buildings to house media pipes for water, sewage, ventilation, electrical and communication. Because ventilation ducts usually have large diameters, these were built separately for buildings with air conditioning systems and the ventilation ducts were often rectangular in shape, so that they could be hidden in the infrastructure, eg in suspended ceilings. In the context of energy saving, which is increasingly being used, more and more pipes and ducts for forced ventilation have been installed. This entails that ventilation ducts of large cross section must be inserted. Since no one in private homes and business buildings appreciates openly laid pipes, which, in addition to aesthetic defects, are also dust collectors and dirt zones, all pipes are installed in the concrete structure. In general, as comfort needs to progress, more conduits for media lines such as electric, audio, heaters, and water are being inserted, so that in many cases there is an acute weakening of the concrete structures.
  • Previously known punching systems allow only reinforcements of the concrete structure in the range of force application areas of columns and the like. They are not suitable for solving the problems caused by media lines causing weakening in the midst of concrete structures. This is particularly because the position alignment with respect to the media lines is not taken into account by the craftsmen. Especially the shear capacity in connection with the cavities would have to be done locally at the point of weakening and not just at supports.
  • This disclosure only relates to conduits routed perpendicular to the ceiling and through the ceiling in the immediate vicinity of the support and solves the problems of puncture resistance.
  • the problem is more varied and often causes problems for the structural engineer, because it is difficult to estimate on site and at the time of acceptance and / or control of the reinforcement, how much the strength is greater due to accumulations of media lines and media lines
  • Diameter is weakened. The more perfect an installation is performed today by the sanitary, electrical and ventilation installer, the more and above all, the larger the number and diameter of the pipes, which are installed in a concrete structure for the subsequent storage of the media lines. The structural engineer is usually not reported, he is confronted with the facts on the spot and must take the reinforcement usually under time pressure.
  • the present invention now has the object a component for concrete structures of to improve the type mentioned above in such a way that in the planning phase means are made available, which can reduce the weakenings caused by media lines locally or even eliminated.
  • means can be made available that can be installed locally at the time of removal of the reinforcement, which, after the pouring of the concrete reinforcement of the concrete structure ensured by clear and for the civil engineer by means of easily recognizable force model in the field
  • the invention is based on a method which allows the civil engineer to take effective measures, both in the planning phase and on site, by means of components with clear force models, in order to reinforce the conventional reinforcement locally by suitable means in such a way that the construction is not overly damaged by media lines weakened, respectively, unnecessary unnecessary oversizing of the same must lead to uneconomical building structures.

  • any two force models and force neutral zones can be combined by the connection via an HS force model 42 in such a way that a horizontal thrust zone 35 is formed which absorbs the horizontal thrust forces 18 (FIG. 3).

  • the result is a clearly quantifiable shear resistance of the concrete structure. It allows the necessary arrangement and guidance of the media lines and the suspension of the resulting tensile forces in such a way that the necessary power flows and concrete pressure diagonals can form a straight line. This is done by arranged on the above systems and devices loops, belts, iron, etc. It is also possible to leave the media lines in place and to arrange the new systems so that the necessary pressure diagonals can form freely despite the media lines.
