  • the subsequent transport of the prefabricated Prestressed concrete elements to the construction site forces to predetermined ones Maximum dimensions for the dimensions of the prestressed concrete elements are not too exceed. Therefore, the individual prestressed concrete elements be assembled on site.

  • the solution according to the invention leads to a direct one Continue the ones running in a first prestressed concrete element Tension wire strands, hereinafter referred to as short first strands, in a second prestressed concrete element into it, which with the first Prestressed concrete element forms a joint.
  • first strands emerging from a first prestressed concrete element into the second prestressed concrete element the power flow always within the two adjacent Prestressed concrete elements guided. This allows one achieve an even flow of force.
  • the advantageous for connecting prestressed concrete elements is characterized in that the first strands emerging from the first prestressed concrete element be inserted into openings in the second prestressed concrete element, the two prestressed concrete elements to be connected side by side be arranged and the first strands in the second Prestressed concrete element can be braced.
