It is known to assist cooling of a combustion chamber in a gas turbine by fixing an exo-skeleton tile structure to an inner annular combustion liner shell. To improve structural integrity of the exo-skeleton tile structure, each tile is formed with at least one rib extending circumferentially across the outer surface of the tile. An end of each rib projects beyond one edge of the tile, like tiles being linked at overlapping edges by the inter-engagement of a projecting rib of one tile with the rib of an adjacent tile. The inter-engaging ends of the ribs are relatively slideable circumferentially to allow thermal expansion and contraction of the exo-skeleton structure, but sockets are provided where the ribs engage so as to resist relative bending of the adjacent tiles about their linked edges and impart rigidity to the structure.
