Definitions

  • the invention relates to a concrete molding compound according to the preamble of claim 1.
  • Constructions and structures such as buildings, bridges, tunnels, are often manufactured using prefabricated elements made of concrete and / or reinforced concrete and / or prestressed concrete, which are summarized under the term concrete preform. It happens that at least in a lot of the construction or the structure connection between two adjacent concrete moldings required or an opening is provided, to which a concrete mold part adjacent. To support an adjacent to the opening concrete molding against acting on this forces and moments, it is necessary to derive the force acting on the corresponding concrete form part forces and moments in, for example, also consisting of concrete moldings adjacent areas of the building or the structure.
  • tunnel structures which are intended to line, for example, mechanically produced tunnels by means of tunnel tubes
  • the tunnel tubes are made of tubbing rings abutting in ring joints.
  • the tubbing rings themselves are in turn each composed of individual, contiguous in longitudinal joints tubbings.
  • the segments of a tubbing ring are supported against each other against, for example, by the mountain pressure, a back pressure or the groundwater from the outside acting on the tubbing ring radial pressure forces.
  • the situation is different in a section of a tunnel structure, in which, for example, a lateral opening is provided in the tunnel tube.
  • This opening may be, for example, a branch or, for example, serve as an escape route or connecting passage, a so-called cross-pass, to an adjacent tunnel tube.
  • the one or more tubbing rings which form the section with the opening in the tunnel tube are interrupted by this opening.
  • the segments of the interrupted Tubbing ring can no longer support each other, and compared to a closed, complete tubbing ring of the power flow between the segments is no longer made, but interrupted.
  • At least the adjacent to an opening segments of a broken through the opening tubbing ring must therefore be supported by segments of adjacent tubbing rings, so that the broken tubbing ring can withstand the radial compressive forces acting on it.
  • Dowel and dowel sleeve can this game have to compensate for a small offset between the tubbing to be joined together.
  • This game can be backfilled or injected by the introduction of a mortar or adhesive.
  • the interior of the load distribution box has an opening towards the inner wall of the tunnel tube forming surface of the tubing.
