Controlled Crack Joint Formwork Element

The secondary reinforced controlled crack joint formwork element for floor/ceiling slabs 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 upper and lower reinforcement layer.
