The installation-friendly and approved system for building renovation
Concrete-concrete shear connector FCC
The fischer concrete-concrete shear connector FCC is an officially approved system for construction renovation. Thanks to its geometry and ease-of-installation, the fischer FCC is a fast, cost-effective alternative to traditional installation using bent iron. The fischer concrete-concrete shear connector FCC is suitable for the renovation of bridges and for increasing their load capacity as well as for increasing the load-bearing capacity of ceilings and reinforcing supports. The fischer FCC can be used with the fischer injection mortars FIS V, FIS V Plus, FIS EM Plus, and FIS SB in accordance with the site conditions. In conjunction with the fischer FIS EM Plus, use in diamond-drilled holes is also permitted.
Due to its geometry and ease of installation, FCC is the rapid and economic alternative compared to the conventional installation method with bent iron.
Dimensioning of the anchorage is possible thanks to the building approval. Thus, the system offers maximum security.
Variable anchoring depths allow for ideal adaptation to the load to be applied, and ensure an optimised installation time and use of materials.
Depending on site conditions, the FCC can be anchored, in compliance with the approval, with the injection mortars FIS SB or FIS EM Plus.
In conjunction with FIS EM Plus, FCC is also approved for use in diamond-drilled drill holes.

You can find detailed information on building materials in the approval document.
Assembly instruction
Functionality
The system consists of injection mortar (FIS SB or FIS EM Plus) and the concrete-concrete shear connector FCC.
The mortar is injected bubble-free from the drill hole base.
The mortar adheres the drill hole wall to the shear connector FCC.
The shear connector is set manually, by lightly rotating it until it reaches the drill hole base.
The tensile and shear forces arising in the joints between the old and new concrete are absorbed by the FCC-H and safely redirected.
