  • Fig. 3 It can be seen that only a textile reinforcement 24 with the composite strip 6 enters into an operative connection, whereas the further textile reinforcement 24 is disposed above the first textile reinforcement 24 completely within the precast concrete part 4 and the pure reinforcement of the concrete is used.
  • the fiber sheets 14 are guided over the projections 12 of the composite strip 6 and / or slipped on site.
  • this operative connection must be in accordance with z. B. liquid concrete are filled. This can be done, for example, by the recess 26 laterally delimiting shuttering element (not shown).
  • first precast concrete part 4 shown here it is also conceivable mirror-symmetrical to the first precast concrete part 4 shown here to arrange another precast concrete 4 on the free half of the support member 2.
  • the recesses 26 of the two arranged on impact precast concrete elements 4 are then arranged opposite each other, so that a casting can be done with liquid concrete from above through the joint and the recesses 26 are filled in accordance with self-venting with liquid concrete. As a result, the desired frictional connection is formed.
