Wooden Ceiling - Invacare EC-Track Installation & Technical Description

• M8 threaded rods, 2 pcs.
• Locking washers, 2 pcs.
(A HKD anchor can be used as an alternative, which the
rods are fixed directly into).
1. Cut the pendle bracket pipe to a length equalling the
distance measured between the concrete ceiling and
the lower face of the suspended ceiling minus 50 mm.
This length is appropriate for a double gypsum layer in
the ceiling and an extra allowance of 12 mm.
2. Cut the threaded rod to a length equalling the distance
between the concrete ceiling and the lower face of
the suspended ceiling minus 10 mm.
3. When installing, first install the top yoke for the center
bracket of the rail Install the yoke as described in
the installation instructions for direct installation in a
concrete ceiling. In this case, however, drill both holes
for the expansion bolts at the same time.
4. When driving in the expansion bolts, leave approx.
15 mm to protruding below the nut, so that you
can screw the coupling nut onto it to its half length.
Counter-tighten the coupling nut against the expansion
bolt nut.
5. Attach a nut approx. 20 mm onto the threaded rod
and screw the threaded rod into the coupling nut, until
it touches the expansion bolt, and counter-tighten
the nut.
6. Attach the bottom yoke and secure it with nuts.
Avoid paint on the bottom section of the
threaded rods until the installation is complete.
7. Prepare the rest of the installation points after a
careful and accurate measuring.
First step of the installation is now complete and
the construction of the suspended ceiling can be
completed.
In the final installation, position the distance pipe in the
suspended ceiling. This pipe will protect the suspended
ceiling. Cut the distance pipe to a length creating a
distance of 1-5 mm between the lower face of the
suspended ceiling and the upper face of the installation
bracket; instead of pipes, nuts and washers can be used
to ensure the recommended distance.

3.2.3 Wooden Ceiling

CAUTION!
– Do not install rails to a wooden ceiling with
tension screws, such as coach screws.
– Do not install rails to a wooden ceiling with
plain wood screws, without having performed
a risk assessment.
Quick Bracket
In some cases, mounting to a ceiling timber work may be
an alternative to mounting to wall or wall support.

It is provided that the ceiling timber work is accessible
from above. When being mounted in the ceiling timber
work, exchange should be placed as reinforcement. When
reinforcing, it is important to select exchange wood that
is dimensioned to tolerate the distance between two
ceiling beams, so sufficient carrying capacity is achieved.
When having marked up to all ceiling brackets in the
ceiling, you should examine whether there is free space
above the ceiling material. When this is done, holes with
a diameter of Ø12.5 mm are drilled through the ceiling
material. The holes may now be localized from above,
they can be prepared for the exchanges, and you may
measure how long the threaded rods should be. The
exchange should cover at least two ceiling beams on each
side of the suspension point. When using exchanges,
two 45x95 mm exchanges should be placed parallel to
each other, at a distance of 14 mm, providing a passage
for an M12 threaded rod. For determining the length of
the threaded rod, determine the ceiling beam's height +
length of exchange wood + ceiling material + 60 mm for
washer and nuts.
Place the adapted threaded rod between the exchange
wood and put in a washer and nut before the threaded
rod is guided further down through the ceiling and position
it with an aluminium plate, a tightening washer and nut
over the exchange wood. The aluminium plate is screwed
into the exchange wood from the top. Let approximately
25 mm threaded rod protrude down under the ceiling
material. A quick ceiling bracket may now be screwed onto
the threaded rod beneath the ceiling material. The ceiling
bracket is fastened with an M12 low nut. The threaded
rod is to be screwed entirely through the nut, but must
protrude further down that below the fitting.
When mounting the bracket and nut, it is important to
use adhesive on bracket as well as nut. When all brackets
are mounted, lift up the rail, adjust the length and secure
it. Before the rail is fastened up to the ceiling, which is
done from above the ceiling, it should be checked that the
exchange wood is resting on both ceiling beams. If not,
something should be placed between.
The nut over the exchange wood is now secured carefully
until the bracket lies evenly with the ceiling material. It is
important not to tighten so much that the ceiling material
is pulled up between the ceiling beams. When this is
done, a steel plate is placed in around the threaded rod
below the exchange wood, and the nut is secured up into
the steel plate, thus locking the position.
Finally, a lock nut is secured against the nut on the upside
of the exchange wood. Trolleys, end stop and rail end
plugs are mounted as described in section 5.2.1.
