Structural design
Preconditions for use
▪
Working wind of 0.2
kN/m
2
(64.4
km/h) is considered
▪
Separate proof must be provided, by a suitably
skilled person, regarding the foundation. Particular
attention must be paid here to the ground-bearing
pressure!
▪
Intermediate anchoring planes may be necessary
while the towers are being erected.
▪
The calculated values are in line with the type test for
'Load-bearing tower Staxo 40', the Calculation guide
'Load-bearing tower Staxo 40' and thus also with
EN
12812 and EN
1993.
▪
In all cases which differ from the stated boundary
conditions, the type-test or the Calculation Guide
must be used as the basis for the dimensioning cal-
culation, to ensure adequate stability.
Such deviations may be due to:
- variations in height
- different wind loads
- different inter-frame spacings
- additional horizontal loads
- single legs
- larger screw-jack extension lengths
- Inclined load-bearing tower
- low vertical loads on free-standing systems
▪
On multi-plane towers with different inter-frame
spaces, it is always the smallest inter-frame space
that determines the design load.
Inclination adjustment
▪
Inclination adjusted with a centering strip (e.g. hexa-
gon bolt M20x230) or Swivel bearing plate for Screw
jack U-head = Screw-jack U-head not restrained.
▪
Inclination adjusted with a wooden wedge or 'Com-
pensating plate' = no effect on the restraint situation.
- e.g. with Wedge for screw jack U-head or Staxo
wedge support
Founding with the 'Compensating plate'
Set-up configurations
Head and base zone configuration
NOTICE
▪
The 'Compensating plate' must be placed
on concrete only.
▪
For the proof against slippage between the
Compensating plate and the concrete, a
friction coefficient of 0.33 must be assumed.
As tower
Number of frame planes = 2
With multiple towerframe-planes
Number of frame planes ≥ 3
