DANGER!
Danger to life from incorrectly installed and threaded
hardware
components!
Incorrect installation and threading of hardware components can
result in dangerous circumstances and cause severe accidents,
even including death.
Therefore:
– For installation and especially for threaded components, observe
the product-specific documentation of the hardware manu-
facturer, the information from the profile manufacturer, and all
contents of the TBDK directive of the Gütegemeinschaft
Schlösser und Beschläge.
For fixing the hardware components, Ø 3.9–4.2 x ... zinc plated and
passivated steel fenestration screws are to be used. In the case of special
climatic conditions, use fenestration screws with additional sealing.
The window fabricator must ensure adequate fixing of the hardware
components , consulting the screw manufacturer if necessary. When fixing
security relevant
, supportive hardware components such as
stay
bearings
and
pivot rests
, the tearing-forces horizontal to the sash plane
surface must be reached in accordance with the following tables (the
tractive -force values depend on the sash weights from the TBDK).
Sash weight in kg
Tractive force in N
1)
60
1650
70
1900
80
2200
90
2450
100
2700
1) acceptable tolerance -10%.
The stated values refer to the stay bearing. These are also valid for the pivot
rest if the fixing is carried out in the same manner as with the stay bearing.
On sash weights up to 80
kg the table’s values are reached as a rule, if
high-quality screws are applied and the screw-fixing into the profile pene-
trates at least 2
profile-walls, whereby the first profile-chamber wall should
be at least 2.8
mm thick.
For sash weights over 80
kg, a supplementary
fi
xing into the reinforcement
pro
fi
le or pro
fi
le insertions according to the pro
fi
le system, is necessary. By
means of applying the 130
kg sash weight frame hinges, the required value
can be achieved also without supplementary measures.
Do not use any acid cross-linked sealing compounds that could lead to
corrosion of the hardware components.
The glazing spacer-block regulations for the glazing method are to be
adhered to.
