Inflatable beam and use of this inflatable beam

An inflatable beam comprising:

• a plurality of industrial seamless hoses comprising three or more industrial seamless hoses, each industrial seamless hose comprising an inner air-tight lining and woven textile braiding extending about the inner air-tight lining, the plurality of industrial seamless hoses extending along an overall first length from a first end to a second end;
• a closure sealing at least one hose of the plurality of industrial hoses at the first end or the second end;
• a common platform mechanically connecting the plurality of industrial seamless hoses at the first end or the second end;
• and
• a plurality of stiff connections spaced along the overall length between the first end and the second end, each stiff connection mechanically connecting the plurality of industrial seamless hoses apart from the common platform and the closure,
• wherein at least one length of at least one hose between adjacent stiff connections is smaller than the length of the other hoses between these connections, and wherein the at least one hose extends beneath one or more of the other hoses to form an inflated arc.
