Air Supported Structures

The Worlds Largest Air Supported Structure

The Worlds Largest Air Supported Structure

August, 2006
Southern Inflatables announced the completion of the installation of the largest span air supported structure ever constructed in the world, 215m x 215m x 45m high (705’ x 705’ x 150’ high). The structure was installed over a waste disposal site, 45m deep (150’) in South Korea.





We are offering all three types of fabric structures:
air supported, frame supported and tensile structures to provide our clients with the best solution for their specific budget and needs. Our Fabric Structures are a surprisingly inexpensive alternative to the conventional "rigid" construction, offering many advantages in terms of lower operating costs and portability to meet the rapidly changing demands.




An air-supported structure utilizes an architectural fabric skin that is inflated by internal air pressure. Because there is no internal frame, the structure consists of only a fabric skin and a blower system that creates the building and defines its shape.

These structures are an inexpensive way to create a very large building, frequently meeting the need for all-weather or around-the-clock facility for warehousing, construction site storage and light manufacturing.

CABLE STRESS RELIEF SYSTEM
Most technologically advanced cable system to reduce the stress on the fabric by 80% and increase the safety factor, thus minimizing the possibility of tear propagation and extending the life expectancy of the fabric.
Allows wind design up to 260 km/h



INFLATION SYSTEM
Primary electric blower (3 HP to 5 HP)
Secondary electric blower (3 Hp to 5 HP) automatically activated upon pressure drop within structure
Combustion engine to power secondary blower, automatically activated upon power failure

FEATURES INCLUDED IN A TYPICAL AIR STRUCTURE PACKAGE
Designed drawings stamped by PE
Double membrane
Cable stress relief system
Doors
Lighting
Heating

ANCHORAGE SYSTEM
Recommend combination of pre-cast concrete grade beam with earth anchors.
Concrete grade beam can be moved each time structure is relocated.
New earth anchors are to be driven in addition.

INFLATION SYSTEM
Primary electric blowers
Secondary electric blowers automatically activated upon pressure drop within structure
Combustion engines to power secondary blowers incase of power failure (automatically activated)
