Abstract

A heat shield with support structure and a number of heat shield blocks secured thereto, having a cold side facing the support structure and a hot side opposite the cold side. At least one recess is arranged in at least one heat shield block circumferential face, connecting the cold to hot side. An opening connecting the recess to the cold side runs in the circumferential face perpendicularly to the cold side. A securing bolt inserted into the opening secures the heat shield block to the support structure. A bolt head protrudes at least partly into the recess. The securing bolt passes through an angled plate having first limb extending substantially parallel to the circumferential face and second limb extending into the recess. The angled plate has a reinforcing device extending beyond the pure angular shape to increase a resistance of the angled plate against bending due to the securing bolt.
