HSI 150-K2-Varia
Provided that no HSI-AH 40 spacers are used – due
to spatial restrictions, for example – it is essential to
take greater care when setting in concrete and later
when compacting the cable duct/conduit trenches
in order to avoid damage caused by poor concrete
compaction, as well as later damage to cable ducts/
conduits as a result of subsidence.
Fixing the cable entry
5
Nail the wall insert to the wooden formwork using the
nail holes provided for this purpose. If the formwork is
made of steel, then attach the wall insert to the reinforce-
ment with wires. Next, close the formwork.
Maintain a distance of at least 5 cm between the
three-ribbed seals and the reinforcing rods. When
doing so, however, ensure that you do not attach the
wire to the three-ribbed seals.
Setting the cable entry in concrete
6
During the process of setting in concrete, make sure
packing is carried out in layers in the vicinity of the wall
insert compacting. Cavities must be avoided. Remove the
formwork once the concrete has set.
Important information regarding setting in concrete:
•
The drop height of the concrete must not exceed
1 meter to prevent separation as reliably as possible
in the HSI 150 wall insert areas and areas at the
base of the wall.
•
If the drop height is exceeded, then it may be
necessary to set up a concrete buffer with a grain
size of 8 mm at a height of at least 30 cm (also
referred to as a connection mix).
•
The individual fill layers must be limited to a maxi-
mum of 50 cm and needled with the internal vibrator.
•
The top layer of concrete in walls must undergo
a thorough repressing process.
For concrete walls in a dual-element construction, it is
important to ensure that the middle three-ribbed seal
is positioned within the in-situ concrete layer.
