The screw solution for multiple fixings

VERSIONS

zinc-plated steel▪

BUILDING MATERIALS

Approved for:Concrete C20/25 to C50/60,cracked, for multiple fixings of non-structural applications

▪

Also suitable for:Concrete C12/15▪Natural stone with dense structure▪

APPROVALS

ADVANTAGES

The concrete screw has beenapproved for the multiple fixing ofnon-load-bearing systems, and assuch is ideal for fixing pipelines,cable conduits etc.

▪

The FBS can be set and installed inone go, thereby saving oninstallation time.

▪

A range of head shapes allows forthe fixing of wide-rangingattachments, and for the idealadaptation to suit the intended use.

▪

APPLICATIONS

Pipes▪Ventilation systems▪Sprinkler systems▪Cable conduits▪Wire hangers▪Punched tapes▪Ceilings▪Temporary internal fixings▪

FUNCTIONING

The FBS type SK and type P aresuitable for push-through installation;whilst the FBS type M8 and typeM8/M10 I are suitable for pre-positioned installation.

▪

When the concrete screw isscrewed into the drill hole, thethread taps into the concrete with apositive fit.

▪

Please note the power outputinformation to ensure that the bestresults are achieved with atangential impact wrench (incl. nutsfitting tangential impact wrenches)(see table).

1) The partial safety factors for material resistance as regulated in the approval as well as a partial safety factor for load actions of γL = 1,4 are considered. As an single anchor counts e.g. an anchor with a spacing s ≥ 3 x hef and an edge distance c ≥ 1,5 x hef. Accurate data see approval.

2) Minimum possible axial spacings resp. edge distance while reducing the permissible load.3) For combinations of tensile loads, shear loads, bending moments as well as reduced edge

distances or spacings (anchor groups) see approval.4) For higher concrete strength classes up to C50/60 higher permissible loads may be possible.
