METHOD OF FORMING A SUPPORT STRUCTURE WITH INTERLOCKING OF ADJACENT COMPARTMENTS

摘要

A method of forming a support structure on a base (18) from a framework (10) which comprises a tube (12) of a flexible material divided by dividing walls (14) of flexible material into an array of compartments (16), is disclosed. Each compartment (16) includes at least one wall (20, 22, 24, 26) including a hollow protrusion or recess (28, 30, 32, 34). In use the framework (10) is located on the base (18) and the compartments (16) are filled with the filler material so that each compartment (16) is adjacent to one or more other compartments (16) filled with the filler material and so that each hollow protrusion (28, 30) fills with the filler material so that each compartment (16) protrudes into or is protruded into by at least one adjacent compartment (16) so as to interlock adjacent compartment (16). This increases the overall strength of the support structure.
