Sliding ceiling connections are required where a ceiling drop
of f ≥ 10 mm is expected.
The designs of the expansion joints are described in
DIN 4102-4 for a drop of f ≤ 20 mm. Designs for a drop of
f ≤ 40 mm, for instance, include general building authority test
certificates (AbP). Conventional installation of fire dampers
is only possible in a wall area that is far below the ceiling
connections of up to 200 mm in height.
•
FK90K fire dampers with installation subframes ER5, on the
other hand, can be fitted directly below rigid ceilings, or with a
clearance of 30 mm to 80 mm. They guide the sliding ceiling
connection around the FK90K fire damper. This is fastened
in such a way that it lowers together with the ceiling and the
ventilation ducts. As shear forces can also be absorbed, the
ventilation ducts do not have to be flexibly connected with the
elastic supports.
