Our shear load connectors (both for diaphragm wall and slab-slab joints) have a DAU, Document of Assessment for fitness of Use, that is the statement of a favorable opinion on the performances of an innovative product and its intended uses within the field of building and civil engineering construction.

DOES AN INCREASE IN THE STRENGTH OF THE STEEL THAT IS USED IN THE REINFORCEMENT IMPROVE THE MECHANICAL BEHAVIOR OF THE WALL?
For control of cracking, the strength of the steel in the reinforcement has no influence on the amount of reinforcement needed, only the area of the cross section.
When the reinforcement is assigned a structural role, the fact the steel is stronger, does not mean necessarily that you reduce the amount of reinforcement in the same proportions. Because by the requirements of the minimum amount, in the vast majority of cases, steel does not display even half of the resistance.
It is the parameter of steel in the masonry reinforcement which really improves the mechanical performance in the wall is ductility, not resistance. For this reason, to prevent cracking, moving forces with the reinforcement it is preferable that the steel has a high percentage of deformation at failure (that is the parameter which determines ductility) than high resistance.

fisufor® plug has an innovative design that makes it possible to achieve the overlap between reinforcement without the need for manipulation, keeping the area of the overlap the same nominal width of the reinforcement.
The ends of the fisufor® plug pieces have a special geometric configuration in the form of a plug that allows the overlap of 250mm without having to cut any wire.
Also, the transverse wire in this area is flattened in order to guarantee the minimum coating of mortar.
- Increases resistance to bending in the wall.
- Guarantees the correct transmission of forces.
- Overlap without any manipulation.
