fire-resistant suspended ceilings are used mainly in two specific cases.

• The first case is to isolate different fire sectors vertically. This action helps restrain fire to its starting point and avoids its propagation to other areas. This solution is highly useful in the case of high-rises since partial sector division might cause the fire to spread easily causing serious problems during evacuation.
• The second case is to protect the various objects found above the ceiling; for example, installations, structures, slabs, etc. According to our requirements, we shall use either application. Our solutions have been tested when fire strikes from below.

Description of assembly

Fix 73 × 30 × 0.5 mm runners with 10 × 100 mm plugs every 500 mm approximately around the ceiling’s perimeter. Then install TC 60/27 profi les at a distance of 610 mm between axes placing such sections crosswise through a Steel grip for TC 60/27 forming 610 × 610 mm frames. Using the steel grip, the M6 rod and the clamps, fi x the structure to the one supporting the ceiling.

Attach both Tecbor® A 12 mm board layers with 3.5 × 45 mm self-tapping screws. Then alternate the second Tecbor® A board with the fi rst one. Use Tecbor® A 12 mm to fi nish off the assembly with a 150 mm wide base-board around the perimeter.

Distance between screws will be approximately 250- 300 mm. Screw heads and inter-board joints will be covered with Tecbor® joint paste.

On top of the suspended ceiling and the IPE 160 metal profi les a 0.6 mm thick ribbed sheet was placed at 550 mm.
