Abstract

The inflatable structure acts as a moulding support when constructing hollow shells of concrete. It has a series of articulating protrusions (3) on part at least of its inner face, the protrusions being formed by inflatable envelopes. Each protrusion may have its own inflating and deflating pipework, the pressure inside the protrusions being controlled simultaneously, or alternatively this can be done independently. Where the structure has a flat wall there can be protrusions on the inside whose internal pressure is such as to keep the wall flat.
