The Integrated Floor Beam (IFB) and the Slim Floor Beam (SFB) stand out for their thoughtful system and remarkable characteristics. The variable design of IFB and SFB profiles offers flexibility in designing facades and roofs. This form of support is particularly applied in places where open spaces without support are needed, such as parking garages or office spaces. They offer installation advantages when placing prefabricated panels, as this can be done relatively efficiently and quickly. Both profile variants offer many additional installation possibilities for cables, pipes, or other components due to their open construction.
Efficient production process
The available rolled H- or I-beams with a welded bottom plate are referred to as SFB (Slim Floor Beam). In contrast to the SFB, an IFB (Integrated Floor Beam) requires an additional production step, namely, distribution in the longitudinal direction. This allows for reducing the height and material usage. An IFB profile can be produced with a wider bottom plate or a narrower top plate. From a production perspective, an SFB beam is more cost-effective.
Adhesion between steel and concrete
To increase the adhesion between floor beam and concrete, boreholes can be distributed along the length of the beam, and during assembly, studbolts or reinforcement steel can be welded to the profile. It is possible to weld bolts to the bearing surface flange, reducing the prefabricated concrete thickness and making the construction material-saving, durable, and economical. Edge beams can be protected against torsion by attaching tie rods or stiffeners to the outside of the profiles.
Torsionally stiff alternative
Because IFB and SFB beams are relatively torsionally weak due to their construction, it is advisable to consider top hat beams (THQ) or plate girders, as these are more torsionally stiff.
