Abstract: A multi-ply tubular inflatable support beam structure that can readily be disassembled to become portable. When inflated the beams are covered with a fabric cover. The tubular beams are sealed on both ends mechanically with a hard plastic device by a sealant, and then clamped. A valve located at one end of the tube permits attachment of an air hose in order to inflate the tubular beams.
