Bulkhead (partition)

A Schott (plural Scots, Scot rare, but not bulkhead ) is a closed partition or, in the older meaning, a fast vorschiebbarer closure. A bulkhead may both air-or liquid-tight and fire-retardant ( fire wall ) designed (see Maritime firefighters ).


In shipbuilding, a bulkhead is an opening in the deck or a bulkhead, which can be closed by lockable hatches to prevent the penetration of water into the original meaning. On merchant ship newbuildings collision bulkheads were from 1929 to duty.

A continuous wall, which divides the interior of a vessel in a water -tight or gas- tight compartments is called a bulkhead. In modern ship such bulkheads in longitudinal and transverse direction ( longitudinal bulkhead and bulkhead ) was used. Top end the so-prepared watertight compartments, the bulkhead deck. The installation of Scots in a body intended to limit flooding on delicious whipped areas to obtain the buoyancy. In the event of an accident they are to maintain the function of the vehicle until the damaged area can be secured. Other tasks include the subdivision and the structural reinforcement of the hull.

The Chinese used as the first bulkhead construction in the construction of the Armada of Admiral Zheng He in the 15th century, probably inspired by the structure of the bamboo tube. In modern times, only from about 1853 ships were created in Scotland construction again. Among the most famous early ships of this type include the Great Eastern ( maiden voyage in 1858 ).

A collision bulkhead is used to reduce water leakage in case of collisions of the vessel with another vessel or obstacle. This bulkhead ranges in altitude of the front ribs from the base line to the deck. The collision bulkhead separates the bow section of the ship from the rest The separated space is used to reduce the collision energy, so that the rest of the ship is likely to remain tight. Most is moved into this area of ​​the ship ballast water or solid ballast. When the ferry collision bulkhead is usually found in the front part of the car decks. It leaves behind the bow visor or the front hatch to separately after the loading and unloading. Collision bulkheads were prescribed for ferries after the Estonia sinking in 1994.

Especially on submarines there are fore and aft a " hatch "; it is a pressure-resistant dome.

Since ships are also threatened by fires, additional firewalls are installed, which are also used in addition to the containment of fire as a strength associations.


In architecture, the term bulkhead or bulkheads often for stabilizing or even space-enclosing design elements will be used. It involves lamellar mounted in parallel stiffeners. Most often they appear as transverse bulkheads on a ceiling constructions are also used as longitudinal bulkheads on facades to support fragile components. In the historical construction wooden beams were used consist in modern architecture Scot mostly of reinforced concrete and may be in addition to their function, style elements.

Fire protection

When you fire a bulkhead or a foreclosure is a brand protection compliant sealing of an opening or a gap in a wall or ceiling to restore the resultant through the hole reduce the fire resistance rating of the wall or ceiling. The sealing such openings is part of the work sector " WKSB " (heat, cold, noise and fire protection), so the insulator; see also: fire test.

Busbar breakthrough in concrete pavement with 2-hour fire resistance rating. The bulkhead is made of stuffed rockwool and liquid silicone, tested in accordance with ULC - S115 for 120 minutes fire resistance and 30 PSI pressure.

Reactive and intumescent sealant in the Grand Coulee Dam. Improper foreclosure in a concrete wall with a 2-hour fire resistance by a liquid sealant ( CP25 ). During a fire, sodium silicate foams containing sealant.
