<p>Individual chambers between limiting elements (2) are made as steel plates with braces to take insulating materials. Double bulkhead connected to adjacent area and at least one side end area of bulkhead is made as a bank area (6) into which piping, cables, and similar can be fed through. Bank area is reinforced using a knee plate (10) and is equipped with a reinforced outer plate (8) at one side, which connects an outlet bend (10) at the side and has a further outer limit in form of covering plate (9). Outer surfaces have a fire-proof coating made of an expandable insulating layer. The fire-proof coating is multi-layered and consists of an insulating coat former which swells to 100mm in event of fire. Insulating material is multi-layered in the formed chambers.</p> |
