Our mix for your wall connections: PFEIFER FS Box

The entirely newly developed PFEIFER-FS System was intended and developed primarily for the connection of precast/cast-in-situ concrete elements to semi-precast elements, so-called double walls. However, other connections with cast-in-situ concrete sections can be simply and flexibly realised.

 PFEIFER FS BoxThe PFEIFER-FS-Box combines the well-known advantages of the PFEIFER-VS® System with the requirements of cast-in-situ concrete construction.

In particular the robust box and the sturdy wire rope are designed especially for cast-in-situ concrete.

The inherent flexibility of the wire rope delivers huge advantages here in comparison with previous solutions such as rigid reinforcing steel, since the wire rope loops can neither get in the way nor cause injuries beforehand. During the assembly processes they can be bent as desired and always spring back into the nominal position afterwards.

Experience the undreamt-of increase in efficiency and implementation safety yourself – and all of that with building authority approval too!

The PFEIFER-FS system is designed for connecting precast elements and double walls. The extended loops engage into the double wall. In combination with a centrally inserted reinforcement bar and the subsequent concreting on the construction site it is a straightforward process to produce a load bearing connections. Alternatively other in-situ concrete connections can be realised. Continue reading

Advantages of JORDAHL ® Punching Shear Reinforcement

For flat slab structures and foundations, JORDAHL®punching shear reinforcement JDA is used to transfer high transverse forces with low formwork and reinforcement requirements and also to optimise the use of space.
Concrete reinforcement
The punching shear resistance can thus be increased by 50% when compared to foundations without punching shear reinforcement, even by 96% compared to ceiling slabs without punching shear reinforcement. Continue reading
