Floor quality
■
The carrying capacity and deformation of the foundation are
defined by the bedding module.
The bedding module k must be at least 15,000 kN/m
3
.
■
The strength at the surface of the foundation upon which the
concrete slab rests is defined by the deformation modules
from the load plate pressure test according to DIN 18134 or
ÖNORM B4417.
■
Load plate diameter DN 300 mm.
■
Ev1 value 75 MN/m
2
, ratio Ev2/Ev1 ≤ 2.20.
■
The entire installation surface must consist of a continuous
base plate with a smooth, oil-free surface in the area of the
load-bearing points.
■
No variable loads (for example, forklift trucks, factory trans-
port units, machines, etc.) are allowed in the direct vicinity of
the machine.
A structural analyst must be consulted under the following condi-
tions:
■
The previously mentioned requirements for an elastically
embedded 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.
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.
