The secondary reinforcedcontrolled crack joint formwork element for the
wall area serves for targeted crack formation along the crack
introducer.
Crack formation as a result of weakening of the concrete
cross-sections takes place due to the integrated separation layer at 1/3
of the component thickness/cross-section thickness.
The reinforcement overlap between the first and second
concreting section is ensured by the installation of the formwork
element between the lateral reinforcement layers.
