■ Concrete quality (corresponding to Class C 25/30 tensile
strength): cylinder compressive strength ≥25 N/mm
2
(3700 psi).
■ Multiple span girders.
A structural analyst must be consulted under the following condi-
tions:
■ The previously named requirements for an elastically embed-
ded base plate are not met.
■ The system is to be set up on a ceiling plate/free-span base
plate.
■ The system is to be set up on fiber-reinforced concrete or
roller-compacted concrete.
■ The system is to be installed on a floor other than the one
named above.
The machine must be damped against oscillations if other sensi-
tive machines are located directly next to the machine or if the
machine is located on a free-span surface which cannot tolerate
these oscillations.
Vibration damping can be implemented by the following meas-
ures:
■ Use Sylomer mats to isolate the machine; thickness 12 mm
(0.47 in), quality SR 1200, violet color, base plate to the sub-
surface and on the side.
■ Structure of the floor (from the bottom to the top):
−
A layer of construction mat.
− At least 300 mm (11.8 in) gravel layer with compaction.
− 120 mm (4.72 in) underbody C12/15 reinforced with 1
mild steel grid layer (steel cross-section lengthwise/cross-
wise 1.96 cm²/m, mesh width lengthwise/crosswise
100 mm, wire thickness lengthwise/crosswise 5 mm).
2.3 Weight load
■ Perform a structural stress analysis of the load-bearing
capacity of the floor surface prior to installation.
■ Take into account the weights of the relevant components
and the load on the support points.
Note
If the concrete floor has the minimum thickness and quality, it
will not have to be subject to a structural check.
